Technical considerations and problems associated with long-term storage of low-level waste  

SciTech Connect (OSTI)

If a state or regional compact does not have adequate disposal capacity for low-level radioactive waste (LLRW), then extended storage of certain LLRW may be necessary. The Nuclear Regulatory Commission (NRC) contracted with Brookhaven National Laboratory (BNL) several years ago (1984--86) to address the technical issues of extended storage. The dual objectives of this study were (1) to provide practical technical assessments for NRC to consider in evaluating specific proposals for extended storage and (2) to help ensure adequate consideration by NRC, Agreement States, and licensees of potential problems that may arise from existing or proposed extended storage practices. In this summary of that study, the circumstances under which extended storage of LLRW would most likely result in problems during or after the extended storage period are considered and possible mitigative measures to minimize these problems are discussed. These potential problem areas include: (1) the degradation of carbon steel and polyethylene containers during storage and the subsequent need for repackaging (resulting in increased occupational exposure), (2) the generation of hazardous gases during storage, and (3) biodegradative processes in LLRW.

Long-Term Stewardship Program Science and Technology Requirements  

SciTech Connect (OSTI)

Many of the United States hazardous and radioactively contaminated waste sites will not be sufficiently remediated to allow unrestricted land use because funding and technology limitations preclude cleanup to pristine conditions. This means that after cleanup is completed, the Department of Energy will have long-term stewardship responsibilities to monitor and safeguard more than 100 sites that still contain residual contamination. Long-term stewardship encompasses all physical and institutional controls, institutions, information, and other mechanisms required to protect human health and the environment from the hazards remaining. The Department of Energy Long-Term Stewardship National Program is in the early stages of development, so considerable planning is still required to identify all the specific roles and responsibilities, policies, and activities needed over the next few years to support the programs mission. The Idaho National Engineering and Environmental Laboratory was tasked with leading the development of Science and Technology within the Long-Term Stewardship National Program. As part of that role, a task was undertaken to identify the existing science and technology related requirements, identify gaps and conflicts that exist, and make recommendations to the Department of Energy for future requirements related to science and technology requirements for long-term stewardship. This work is summarized in this document.

Long-term corrosion testing pan.  

SciTech Connect (OSTI)

This document describes the testing and facility requirements to support the Yucca Mountain Project long-term corrosion testing needs. The purpose of this document is to describe a corrosion testing program that will (a) reduce model uncertainty and variability, (b) reduce the reliance upon overly conservative assumptions, and (c) improve model defensibility. Test matrices were developed for 17 topical areas (tasks): each matrix corresponds to a specific test activity that is a subset of the total work performed in a task. A future document will identify which of these activities are considered to be performance confirmation activities. Detailed matrices are provided for FY08, FY09 and FY10 and rough order estimates are provided for FY11-17. Criteria for the selection of appropriate test facilities were developed through a meeting of Lead Lab and DOE personnel on October 16-17, 2007. These criteria were applied to the testing activities and recommendations were made for the facility types appropriate to carry out each activity. The facility requirements for each activity were assessed and activities were identified that can not be performed with currently available facilities. Based on this assessment, a total of approximately 10,000 square feet of facility space is recommended to meet all future testing needs, given that all testing is consolidated to a single location. This report is a revision to SAND2007-7027 to address DOE comments and add a series of tests to address NWTRB recommendations.

Transuranic waste: long-term planning  

SciTech Connect (OSTI)

Societal concerns for the safe handling and disposal of toxic waste are behind many of the regulations and the control measures in effect today. Transuranic waste, a specific category of toxic (radioactive) waste, serves as a good example of how regulations and controls impact changes in waste processing - and vice versa. As problems would arise with waste processing, changes would be instituted. These changes improved techniques for handling and disposal of transuranic waste, reduced the risk of breached containment, and were usually linked with regulatory changes. Today, however, we face a greater public awareness of and concern for toxic waste control; thus, we must anticipate potential problems and work on resolving them before they can become real problems. System safety analyses are valuable aids in long-term planning for operations involving transuranic as well as other toxic materials. Examples of specific system safety analytical methods demonstrate how problems can be anticipated and resolution initiated in a timely manner having minimal impacts upon allocation of resource and operational goals. 7 refs., 1 fig.

Long-term Repository Benefits of Using Cermet Waste Packages  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Long-Term Benefits Long-Term Benefits Long-term Repository Benefits of Using Cermet Waste Packages A cermet waste package may improve the long-term performance of the YM repository by two mechanisms: reducing (1) the potential for nuclear criticality in the repository and (2) the long-term release rate of radionuclides from the waste package. In the natural environment, the centers of uranium ore deposits have remained intact for very long time periods while the outer edges of the ore deposit have degraded. A cermet waste package may operate in the same way. The sacrificial, slow degradation of the waste package and the DU oxide protects the SNF uranium dioxide in the interior of the package long after the package has failed.

Site transition framework for long-term surveillance and maintenance  

SciTech Connect (OSTI)

This document provides a framework for all U.S. Department of Energy (DOE) facilities and sites where DOE may have anticipated long-term surveillance and maintenance (LTSM) responsibilities. It is a tool to help facilitate a smooth transition from remediation to LTSM, providing a systematic process for affected parties to utilize in analyzing the baseline to understand and manage the actions from EM mission completion through a sites transition into LTSM. The framework is not meant to provide an exhaustive list of the specific requirement and information that are needed. Sites will have unique considerations that may not be adequately addressed by this tool, and it is anticipated that a team comprised of the transferring and receiving organization will use judgment in utilizing this augmenting with other DOE guidance. However the framework should be followed to the extent possible at each site; and adapted to accommodate unique site-specific requirements, needs, and documents. Since the objective of the tool is facilitate better understanding of the conditions of the site and the actions required for transfer, the transition team utilizing the checklist is expected to consult with management of both the receiving and transferring organization to verify that major concerns are addressed. Ideally, this framework should be used as early in the remediation process as possible. Subsequent applications of the Site Transition Framework (STF) to the site should be conducted periodically and used to verify that all appropriate steps have been or will be taken to close-out the site and that actions by both organization are identified to transfer the site to LTSM. The requirements are provided herein.

Long-term serviceability of elastomers in modern engine coolants  

SciTech Connect (OSTI)

The aging of elastomers in engine coolants after extended periods of service can be both a physical process (stress/strain relaxation) and/or a chemical change. Engine coolants are essentially aqueous and non-aqueous electrolytes coupled with inorganic inhibitor systems, as well as new organic acid systems. The long-term effects of this environment are reviewed. Chemical and functional tests are utilized to model these aging processes. This review will offer a better understanding of the long-term suitability of typical candidate elastomers.

Long-Term Carbon Injection Field Test for > 90% Long-Term Carbon Injection Field Test for > 90% Mercury Removal for a PRB Unit with a Spray Drier and Fabric Filter The intent of DOE's Phase I and II field tests was to work with industry to evaluate the most promising mercury control technologies at full-scale in a variety of configurations. Although longer-term tests were conducted, the test period was not sufficient to answer many fundamental questions about long-term consistency of mercury removal and reliability of the system when integrated with plant processes. As the technologies move towards commercial implementation, it is critical to accurately define the mercury removal performance and costs so that power companies and policy makers can make informed decisions. Therefore, the overall objective of this Phase III project is to determine the mercury removal performance, long-term emissions variability, and associated O&M costs of activated carbon injection for >90% mercury control over a 10 to 12 month period on a unit that represents the combination of coal and emission control equipment that will be used for many new and existing power plants.

Long-Term Assessment of Critical Radionuclides and Associated Environmental Media at the Savannah River Site  

SciTech Connect (OSTI)

During the operational history of the Savannah River Site (SRS), many different radionuclides have been released from site facilities. However, only a relatively small number of the released radionuclides have been significant contributors to doses and risks to the public. At SRS dose and risk assessments indicate tritium oxide in air and surface water, and Cs-137 in fish and deer have been, and continue to be, the critical radionuclides and pathways. In this assessment, indepth statistical analyses of the long-term trends of tritium oxide in atmospheric and surface water releases and Cs-137 concentrations in fish and deer are provided. Correlations also are provided with 1) operational changes and improvements, 2) geopolitical events (Cold War cessation), and 3) recent environmental remediation projects and decommissioning of excess facilities. For example, environmental remediation of the F- and H-Area Seepage Basins and the Solid Waste Disposal Facility have resulted in a measurable impact on the tritium oxide flux to the onsite Fourmile Branch stream. Airborne releases of tritium oxide have been greatly affected by operational improvements and the end of the Cold War in 1991. However, the effects of SRS environmental remediation activities and ongoing tritium operations on tritium concentrations in the environment are measurable and documented in this assessment. Controlled hunts of deer and feral hogs are conducted at SRS for approximately six weeks each year. Before any harvested animal is released to a hunter, SRS personnel perform a field analysis for Cs-137 concentrations to ensure the hunter's dose does not exceed the SRS administrative game limit of 0.22 millisievert (22 mrem). However, most of the Cs-137 found in SRS onsite deer is not from site operations but is from nuclear weapons testing fallout from the 1950's and early 1960's. This legacy source term is trended in the SRS deer, and an assessment of the ''effective'' half-life of Cs-137 in deer (including the physical decay half-life and the environmental dispersion half-life) is provided. The ''creek mouth'' fisherman is the next most critical pathway at SRS. On an annual basis, three species of fish (panfish, catfish, and bass) are sampled from the mouths of the five SRS streams. Three composites of up to five fish of each species are analyzed from each sampling location. Long-term trending of the Cs-137 concentrations in fish and the subsequent doses from consumption of SRS fish is provided.

Long-term planetary integration with individual time steps  

E-Print Network [OSTI]

We describe an algorithm for long-term planetary orbit integrations, including the dominant post-Newtonian effects, that employs individual timesteps for each planet. The algorithm is symplectic and exhibits short-term errors that are $O(\\epsilon\\Omega^2\\tau^2)$ where $\\tau$ is the timestep, $\\Omega$ is a typical orbital frequency, and $\\epsilon\\ll1$ is a typical planetary mass in solar units. By a special starting procedure long-term errors over an integration interval $T$ can be reduced to $O(\\epsilon^2\\Omega^3\\tau^2T)$. A sample 0.8 Myr integration of the nine planets illustrates that Pluto can have a timestep more than 100 times Mercury's, without dominating the positional error. Our algorithm is applicable to other $N$-body systems.

EU in the struggle for global governance: geopolitical ethics  

Science Journals Connector (OSTI)

This article argues in favour of a coherent and active European Union foreign policy based on the idea of 'geopolitical ethics'. In the first part of the article, the situation of the international system since 1990 is outlined. It seems that after the financial crisis of 2008 the world has lost its global governor - the USA - and thus plunged into a non-polar structure. The second part of the article will present the concept of 'geopolitical ethics'. Namely, analogical to the personalistic 'ethics of responsibility', in which an individual is the primary focus, 'geopolitical ethics' considers the nation as the constituent unit in the international system. In the final section, two case studies, both involving the internal (policy making) and external (policy implementation) dimensions of the EU's grand strategy - 'geopolitical ethics', are presented.

World oil and geopolitics to the year 2010  

SciTech Connect (OSTI)

This paper focuses on the interplay of market forces and politics in the world oil market projected to the year 2010. It argues that world oil demand will increase considerably, with Asian demand growing the fastest. Given that the growth of oil supply of producers outside the Organization of the Petroleum Exporting Countries (OPEC) will be trivial, the call on OPEC oil will increase substantially. Yet, given their declining per-capita oil revenues, OPEC members may not be able to make timely investments in required upstream projects. If this happens, the supply constraint will lead to higher prices and intensified international competition for Arabian/Persian Gulf oil. Thus, foreign investment will be needed increasingly in OPEC states if prices are to remain stable. But geopolitical and institutional barriers to foreign investment in many OPEC members hinder foreign investment. It is imperative that major players in the world oil market cooperate to reduce such barriers in time to ensure that supply corresponds to rising demand. 22 refs., 8 figs., 10 tabs.

2003 Long-Term Surveillance and Maintenance Program Report  

SciTech Connect (OSTI)

Radioactive waste was created by the Federal Government and private industry at locations around the country in support of national defense, research, and civilian power-generation programs. If not controlled, much of this legacy waste would remain hazardous to human health and the environment indefinitely. Current technology does not allow us to render this waste harmless, so the available methods to control risk rely on consolidation, isolation, and long-term management of the waste. The U.S. Department of Energy (DOE) has an obligation to safely control the radioactive waste and to inform and train future generations to maintain and, perhaps, improve established protections. DOE is custodian for much of the radioactive and other hazardous waste under control of the Federal Government. DOE established the Formerly Utilized Sites Remedial Action Program (FUSRAP) in 1974 and the Defense Decontamination and Decommissioning (D&D) Program and the Surplus Facilities Management Program in the 1980s. Congress passed the Uranium Mill Tailings Radiation Control Act (UMTRCA) in 1978. These federal programs and legislation were established to identify, remediate, and manage legacy waste. Remedial action is considered complete at a radioactive waste site when the identified hazardous material is isolated and the selected remedial action remedy is in place and functioning. Radioactive or other hazardous materials remain in place as part of the remedy at many DOE sites. Long-term management of radioactive waste sites incorporates a set of actions necessary to maintain protection of human health and the environment. These actions include maintaining physical impoundment structures in good repair to ensure that they perform as designed, preventing exposure to the wastes by maintaining access restrictions and warnings, and recording site conditions and activities for future custodians. Any actions, therefore, that will prevent exposure to the radioactive waste now or in the future are part of long-term site management. In response to post-closure care requirements set forth in UMTRCA, DOE Headquarters established the Long-Term Surveillance and Maintenance (LTS&M) Program in 1988 at the DOE office in Grand Junction, Colorado. The program assumed long-term management responsibility for sites remediated under UMTRCA and other programs. Since its inception, the LTS&M Program has evolved in response to changing stakeholder needs, improvements in technology, and the addition of more DOE sites as remediation is completed. The mission of the LTS&M Program was to fulfill DOEs responsibility to implement all activities necessary to ensure regulatory compliance and to protect the public and the environment from long-lived wastes associated with the nations nuclear energy, weapons, and research activities. Key components of the LTS&M Program included stakeholder participation, site monitoring and maintenance, records and information management, and research and technology transfer. This report presents summaries of activities conducted in 2003 in fulfillment of the LTS&M Program mission. On December 15, 2003, DOE established the Office of Legacy Management (LM) to allow for optimum management of DOEs legacy responsibilities. Offices are located in Washington, DC, Grand Junction, Colorado, Morgantown, West Virginia, and Pittsburgh, Pennsylvania, to perform long-term site management, land management, site transition support, records management, and other related tasks. All activities formerly conducted under the LTS&M Program have been incorporated into the Office of Land and Site Management (LM50), as well as management of remedies involving ground water and surface water contaminated by former processing activities.

Long-Term Damped Dynamics of the Extensible Suspension Bridge  

E-Print Network [OSTI]

This work is focused on the doubly nonlinear equation, whose solutions represent the bending motion of an extensible, elastic bridge suspended by continuously distributed cables which are flexible and elastic with stiffness k^2. When the ends are pinned, long-term dynamics is scrutinized for arbitrary values of axial load p and stiffness k^2. For a general external source f, we prove the existence of bounded absorbing sets.When f is timeindependent, the related semigroup of solutions is shown to possess the global attractor of optimal regularity and its characterization is given in terms of the steady states of the problem.

Corrosion of Spent Nuclear Fuel: The Long-Term Assessment  

SciTech Connect (OSTI)

Spent nuclear fuel, essentially U{sub 2}, accounts for over 95% of the total radioactivity of all of the radioactive wastes in the United States that require disposal, disposition or remediation. The UO{sub 2} in SNF is not stable under oxiding conditions and may also be altered under reducing conditions. The alteration of SNF results in the formation of new uranium phases that can cause the release or retardation of actinide and fission product radionuclides. Over the long term, and depending on the extent to which the secondary uranium phases incorporate fission products and actinides, these alteration phases become the near-field source term.

Regulating for the long term: SMCRA and acid mine drainage  

SciTech Connect (OSTI)

With the passage of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), regulators and industry representatives expected to solve the problem of pollution of the Nation`s waterways caused by acidic discharges from coal mines. Eighteen years after the passage of SMCRA, hard issues of predicting, regulating and treating acid mine drainage remain. Acid mine drainage is most common in the coal seams of the Midwest and Appalachia: Pennsylvania, West Virginia, Maryland, Ohio, Illinois, and Tennessee. This article discusses regulation of coal mines and acid mine drainage for the long term.

Adapting Advances in Remediation Science to Long-Term Surveillance  

SciTech Connect (OSTI)

Several facets of groundwater remediation stand to gain from the advances made during recent years in disciplines that contribute to remediation science. Engineered remedies designed to aggressively remove subsurface contamination should benefit from this progress, and more passive cleanup methods and the long-term monitoring of such passive approaches may benefit equally well if not more. The U.S. Department of Energy Office of Legacy Management (LM) has adopted a strategic plan that is designed to take advantage of technological improvements in the monitoring and assessment of both active and passive groundwater remedies. Flexible adaptation of new technologies, as they become available, to long-term surveillance at LM sites is expected to reduce site stewardship costs while ensuring the future protection of human health and the environment. Some of the technologies are expected to come from government initiatives that focus on the needs of subsurface monitoring. Additional progress in monitoring science will likely result from continual improvements in our understanding of contaminant fate-and-transport processes in the groundwater and the vadose zone.

A model for Long-term Industrial Energy Forecasting (LIEF)  

SciTech Connect (OSTI)

The purpose of this report is to establish the content and structural validity of the Long-term Industrial Energy Forecasting (LIEF) model, and to provide estimates for the model's parameters. The model is intended to provide decision makers with a relatively simple, yet credible tool to forecast the impacts of policies which affect long-term energy demand in the manufacturing sector. Particular strengths of this model are its relative simplicity which facilitates both ease of use and understanding of results, and the inclusion of relevant causal relationships which provide useful policy handles. The modeling approach of LIEF is intermediate between top-down econometric modeling and bottom-up technology models. It relies on the following simple concept, that trends in aggregate energy demand are dependent upon the factors: (1) trends in total production; (2) sectoral or structural shift, that is, changes in the mix of industrial output from energy-intensive to energy non-intensive sectors; and (3) changes in real energy intensity due to technical change and energy-price effects as measured by the amount of energy used per unit of manufacturing output (KBtu per constant $ of output). The manufacturing sector is first disaggregated according to their historic output growth rates, energy intensities and recycling opportunities. Exogenous, macroeconomic forecasts of individual subsector growth rates and energy prices can then be combined with endogenous forecasts of real energy intensity trends to yield forecasts of overall energy demand. 75 refs.

Long-term Monitoring Plan for the Central Nevada Test Area  

SciTech Connect (OSTI)

The groundwater flow and transport model of the Faultless underground nuclear test conducted at the Central Nevada Test Area (CNTA) was accepted by the state regulator and the environmental remediation efforts at the site have progressed to the stages of model validation and long-term monitoring design. This report discusses the long-term monitoring strategy developed for CNTA. Subsurface monitoring is an expensive and time-consuming process, and the design approach should be based on a solid foundation. As such, a thorough literature review of monitoring network design is first presented. Monitoring well networks can be designed for a number of objectives including aquifer characterization, parameter estimation, compliance monitoring, detection monitoring, ambient monitoring, and research monitoring, to name a few. Design methodologies also range from simple hydrogeologic intuition-based tools to sophisticated statistical- and optimization-based tools. When designing the long-term monitoring well network for CNTA, a number of issues are carefully considered. These are the uncertainty associated with the subsurface environment and its implication for monitoring design, the cost associated with monitoring well installation and operation, the design criteria that should be used to select well locations, and the potential conflict between different objectives such as early detection versus impracticality of placing wells in the vicinity of the test cavity. Given these considerations and the literature review of monitoring design studies, a multi-staged approach for development of the long-term monitoring well network for CNTA is proposed. This multi-staged approach will proceed in parallel with the validation efforts for the groundwater flow and transport model of CNTA. Two main stages are identified as necessary for the development of the final long-term monitoring well network for the site. The first stage is to use hydrogeologic expertise combined with model simulations and probability based approaches to select the first set of monitoring wells that will serve two purposes. The first is to place the wells in areas likely to encounter migration pathways thereby enhancing the probability of detecting radionuclide migration in the long run. The second objective is crucial in the short run and is aimed at using this set of wells to collect validation data for the model. The selection criteria should thus balance these two objectives. Based on the results of the validation process that progresses concurrently with the first monitoring stage, either more wells will be needed in this first stage or the second stage will be initiated. The second monitoring design stage will be based on an optimum design methodology that uses a suitable statistical approach, combined with an optimization approach, to augment the initial set of wells and develop the final long-term monitoring network. The first-stage probabilistic analysis conducted using the CNTA model indicates that the likelihood of migration away from the test cavity is very low and the probability of detecting radionuclides in the next 100 years is extremely low. Therefore, it is recommended to place one well in the downstream direction along the model longitudinal centerline (i.e., directly north of the working point), which is the location with the highest probability of encountering the plume. Lack of significant plume spreading, coupled with the extremely low velocities, suggests that this one well is sufficient for the first stage. Data from this well, and from additional wells located with validation as the prime objective, will benefit the model validation process. In the long run, this first monitoring well is going to be crucial for the long-term monitoring of the site (assuming that the flow model is validated), as it will be the most likely place to detect any plume migration away from the cavity.

Long term distribution network planning considering urbanity uncertainties  

Science Journals Connector (OSTI)

This paper addresses the problem of long term distribution network planning under urbanity uncertainties. Unpredictable urbanity plans are expected facts in developing/under developed countries. This type of uncertainties make it difficult to implement designed network in the future and leads to increasing operational costs including loss and outage costs. In this paper we presented a novel approach for distribution network planning which in addition of eliminating harmful effects of urbanity uncertainties, leads to easy management and operation of resulted network. In this approach several points of study region with high accessibility are selected as candidate embranchment points and optimal connection configuration of load points to the embranchment points is determined by genetic algorithm considering investment, loss and also customer interruption costs. Afterward, final structure of network is designed by branch exchange method considering the embranchment points as representative to load points in their service area. The performance of the proposed approach is assessed on a test distribution network.

Long-term behavior of municipal solid waste landfills  

Science Journals Connector (OSTI)

A method is presented to predict the long-term behavior of element concentrations (non-metals and metals) in the leachate of a municipal solid waste (MSW) landfill. It is based on water flux and concentration measurements in leachates over one year, analysis of drilled cores from MSW landfills and leaching experiments with these samples. A mathematical model is developed to predict the further evolution of annual flux-weighted mean element concentrations in leachates after the intensive reactor phase, i.e. after the gas production has dropped to a very low level. The results show that the organic components are the most important substances to control until the leachate is compatible with the environment. This state of low emissions, the so-called final storage quality, will take many centuries to be achieved in a moderate climate.

Differential maps, difference maps, interpolated maps, and long term prediction  

SciTech Connect (OSTI)

Mapping techniques may be thought to be attractive for the long term prediction of motion in accelerators, especially because a simple map can approximately represent an arbitrarily complicated lattice. The intention of this paper is to develop prejudices as to the validity of such methods by applying them to a simple, exactly solveable, example. It is shown that a numerical interpolation map, such as can be generated in the accelerator tracking program TEAPOT, predicts the evolution more accurately than an analytically derived differential map of the same order. Even so, in the presence of appreciable'' nonlinearity, it is shown to be impractical to achieve accurate'' prediction beyond some hundreds of cycles of oscillation. This suggests that the value of nonlinear maps is restricted to the parameterization of only the leading'' deviation from linearity. 41 refs., 6 figs.

Demonstrating the Safety of Long-Term Dry Storage - 13468  

SciTech Connect (OSTI)

Commercial nuclear plants in the United States were originally designed with the expectation that used nuclear fuel would be moved directly from the reactor pools and transported off site for either reprocessing or direct geologic disposal. However, Federal programs intended to meet this expectation were never able to develop the capability to remove used fuel from reactor sites - and these programs remain stalled to this day. Therefore, in the 1980's, with reactor pools reaching capacity limits, industry began developing dry cask storage technology to provide for additional on-site storage. Use of this technology has expanded significantly since then, and has today become a standard part of plant operations at most US nuclear sites. As this expansion was underway, Federal programs remained stalled, and it became evident that dry cask systems would be in use longer than originally envisioned. In response to this challenge, a strong technical basis supporting the long term dry storage safety has been developed. However, this is not a static situation. The technical basis must be able to address future challenges. Industry is responding to one such challenge - the increasing prevalence of high burnup (HBU) used fuel and the need to provide long term storage assurance for these fuels equivalent to that which has existed for lower burnup fuels over the past 25 years. This response includes a confirmatory demonstration program designed to address the aging characteristics of HBU fuel and set a precedent for a learning approach to aging management that will have broad applicability across the used fuel storage landscape.

SULFURIC ACID REMOVAL PROCESS EVALUATION: LONG-TERM RESULTS  

SciTech Connect (OSTI)

The objective of this project is to demonstrate the use of alkaline reagents injected into the furnace of coal-fired boilers as a means of controlling sulfuric acid emissions. The project is being co-funded by the U.S. DOE National Energy Technology Laboratory, under Cooperative Agreement DE-FC26-99FT40718, along with EPRI, the American Electric Power Company (AEP), FirstEnergy Corp., the Tennessee Valley Authority, and Dravo Lime, Inc. Sulfuric acid controls are becoming of increasing interest to power generators with coal-fired units for a number of reasons. Sulfuric acid is a Toxic Release Inventory species and can cause a variety of plant operation problems such as air heater plugging and fouling, back-end corrosion, and plume opacity. These issues will likely be exacerbated with the retrofit of selective catalytic reduction (SCR) for NO{sub x} control on many coal-fired plants, as SCR catalysts are known to further oxidize a portion of the flue gas SO{sub 2} to SO{sub 3}. The project previously tested the effectiveness of furnace injection of four different calcium-and/or magnesium-based alkaline sorbents on full-scale utility boilers. These reagents were tested during four one- to two-week tests conducted on two FirstEnergy Bruce Mansfield Plant (BMP) units. One of the sorbents tested was a magnesium hydroxide byproduct slurry produced from a modified Thiosorbic{reg_sign} Lime wet flue gas desulfurization system. The other three sorbents are available commercially and include dolomite, pressure-hydrated dolomitic lime, and commercial magnesium hydroxide. The dolomite reagent was injected as a dry powder through out-of-service burners, while the other three reagents were injected as slurries through air-atomizing nozzles inserted through the front wall of the upper furnace, either across from the nose of the furnace or across from the pendant superheater tubes. After completing the four one- to two-week tests, the most promising sorbents were selected for longer-term (approximately 25-day) full-scale tests on two different units. The longer-term tests were conducted to confirm the effectiveness of the sorbents tested over extended operation on two different boilers, and to determine balance-of-plant impacts. The first long-term test was conducted on FirstEnergy's BMP, Unit 3, and the second test was conducted on AEP's Gavin Plant, Unit 1. The Gavin Plant testing provided an opportunity to evaluate the effects of sorbent injected into the furnace on SO{sub 3} formed across an operating SCR reactor. This report presents the results from those long-term tests. The tests determined the effectiveness of injecting commercially available magnesium hydroxide slurry (Gavin Plant) and byproduct magnesium hydroxide slurry (both Gavin Plant and BMP) for sulfuric acid control. The results show that injecting either slurry could achieve up to 70 to 75% overall sulfuric acid removal. At BMP, this overall removal was limited by the need to maintain acceptable electrostatic precipitator (ESP) particulate control performance. At Gavin Plant, the overall sulfuric acid removal was limited because the furnace injected sorbent was less effective at removing SO{sub 3} formed across the SCR system installed on the unit for NOX control than at removing SO{sub 3} formed in the furnace. The long-term tests also determined balance-of-plant impacts from slurry injection during the two tests. These include impacts on boiler back-end temperatures and pressure drops, SCR catalyst properties, ESP performance, removal of other flue gas species, and flue gas opacity. For the most part the balance-of-plant impacts were neutral to positive, although adverse effects on ESP performance became an issue during the BMP test.

Collaboration in long-term stewardship at DOE Hanford Site  

SciTech Connect (OSTI)

The U.S. Department of Energy's (DOE) Hanford Site comprises approximately 1,517 km{sup 2} (586 mi{sup 2}) of land in southeastern Washington. The site was established in 1943 as part of the Manhattan Project to produce plutonium for the nation's nuclear weapons program. As the Cold War era came to an end, the mission of the site transitioned from weapons production to environmental cleanup. As the River Corridor area of the site cleanup is completed, the mission for that portion of the site will transition from active cleanup to continued protection of environment through the Long-Term Stewardship (LTS) Program. The key to successful transition from cleanup to LTS is the unique collaboration among three (3) different DOE Programs and three (3) different prime contractors with each contractor having different contracts. The LTS Program at the site is a successful model of collaboration resulting in efficient resolution of issues and accelerated progress that supports DOE's Richland Office 2015 Vision for the Hanford Site. The 2015 Vision for the Hanford Site involves shrinking the active cleanup footprint of the surface area of the site to approximately 20 mi{sup 2} on the Central Plateau. Hanford's LTS Program is defined in DOE's planning document, Hanford Long-Term Stewardship Program Plan, DOE/RL-2010-35 Rev 1. The Plan defines the relationship and respective responsibilities between the federal cleanup projects and the LTS Program along with their respective contractors. The LTS Program involves these different parties (cleanup program and contractors) who must work together to achieve the objective for transition of land parcels. Through the collaborative efforts with the prime contractors on site over the past two years, 253.8 km{sup 2} (98 mi{sup 2}) of property has been successfully transitioned from the cleanup program to the LTS Program upon completion of active surface cleanup. Upcoming efforts in the near term will include transitioning another large parcel that includes one of the six (6) cocooned reactors on site. These accomplishments relied upon the transparency between DOE cleanup programs and their contractors working together to successfully transition the land while addressing the challenges that arise. All parties, the three different DOE Programs and their respective prime contractors are dedicated to working together and continuing the progress of transitioning land to LTS, in alignment with the Program Plan and compliant with contractual requirements. This paper highlights the accomplishments and collaborative efforts to address the challenges faced as work progresses from the cleanup to transitioning of land parcels to LTS Program.

LONG-TERM STEWARDSHIP AT DOE HANFORD SITE - 12575  

SciTech Connect (OSTI)

The U.S. Department of Energy's (DOE) Hanford Site is located in southeast Washington and consists of 1,518 square kilometers (586 square miles) of land. Established in 1943 as part of the Manhattan Project, Hanford workers produced plutonium for our nation's nuclear defense program until the mid 1980's. Since then, the site has been in cleanup mode that is being accomplished in phases. As we achieve remedial objectives and complete active cleanup, DOE will manage Hanford land under the Long-Term Stewardship (LTS) Program until completion of cleanup and the site becomes ready for transfer to the post cleanup landlord - currently planned for DOE's Office of Legacy Management (LM). We define Hanford's LTS Program in the ''Hanford Long-Term Stewardship Program Plan,'' (DOE/RL-201 0-35)[1], which describes the scope including the relationship between the cleanup projects and the LTS Program. DOE designed the LTS Program to manage and provide surveillance and maintenance (S&M) of institutional controls and associated monitoring of closed waste sites to ensure the protection of human health and the environment. DOE's Richland Operations Office (DOE-RL) and Hanford cleanup and operations contractors collaboratively developed this program over several years. The program's scope also includes 15 key activities that are identified in the DOE Program Plan (DOE/RL-2010-35). The LTS Program will transition 14 land segments through 2016. The combined land mass is approximately 570 square kilometers (220 square miles), with over 1,300 active and inactive waste sites and 3,363 wells. Land segments vary from buffer zone property with no known contamination to cocooned reactor buildings, demolished support facilities, and remediated cribs and trenches. DOE-RL will transition land management responsibilities from cleanup contractors to the Mission Support Contract (MSC), who will then administer the LTS Program for DOE-RL. This process requires an environment of cooperation between the contractors and DOE-RL. Information Management (IM) is a key part of the LTS program. The IM Program identifies, locates, stores, protects and makes accessible Hanford LTS records and data to support the transfer of property ultimately to LM. As such, DOE-RL manages the Hanford LTS Program in a manner consistent with LM's goals, policies, and procedures.

System - Gasifier Optimization and Plant Supporting Systems System - Gasifier Optimization and Plant Supporting Systems Long-Term Refractory Durability Tests National Carbon Capture Center at the Power Systems Development Facility Southern Company Services, Inc. Project Number: NT0000749 Project Description The National Carbon Capture Center Transport Gasifier consists of an assembly of refractory-lined pipe that includes a mixing zone, a riser, a solids separation and collection unit, and a solids recycle section. By combining the use of strategically placed, precision instrumentation and monitoring controlled solids inventory and solids circulation with the ability to operate across a wide range of flow rates and adjustable process conditions, the facility is monitoring and measuring slag/refractory interactions and testing various materials for durability. New materials research and development results, provided to manufacturers, aims to improve gasifier availability and reduce costs associated with plant shut-downs for repairs. In the most severe slagging gasifiers, refractories can require replacement every three months, where the gasifier system is shut down for one to two weeks, costing millions of dollars.

Long-term proliferation and safeguards issues in future technologies  

SciTech Connect (OSTI)

The purpose of the task was to assess the effect of potential new technologies, nuclear and non-nuclear, on safeguards needs and non-proliferation policies, and to explore possible solutions to some of the problems envisaged. Eight subdivisions were considered: New Enrichment Technologies; Non-Aqueous Reprocessing Technologies; Fusion; Accelerator-Driven Reactor Systems; New Reactor Types; Heavy Water and Deuterium; Long-Term Storage of Spent Fuel; and Other Future Technologies (Non-Nuclear). For each of these subdivisions, a careful review of the current world-wide effort in the field provided a means of subjectively estimating the viability and qualitative probability of fruition of promising technologies. Technologies for which safeguards and non-proliferation requirements have been thoroughly considered by others were not restudied here (e.g., the Fast Breeder Reactor). The time scale considered was 5 to 40 years for possible initial demonstration although, in some cases, a somewhat optimistic viewpoint was embraced. Conventional nuclear-material safeguards are only part of the overall non-proliferation regime. Other aspects are international agreements, export controls on sensitive technologies, classification of information, intelligence gathering, and diplomatic initiatives. The focus here is on safeguards, export controls, and classification.

Science Journals Connector (OSTI)

Most of the energy produced in Quebec comes from renewable sources. The concept of wind energy emerged in the late 1990s and has since become a complementary source of energy alongside hydroelectricity. Wind farms are generally seen as a good sustainable way to produce energy. However they are not implemented without some impact on the environment. SNC-Lavalin Environment has performed many surveys in recent years for wind farm projects including noise measurements both before and after their commissioning. This presentation will give an overview of one such project where long term noise and vibration measurements where conducted. Vibration measurements as well as outdoor indoor and low frequencies noise measurements were completed both with and without the wind turbines in operation. Data will be presented showing different problems encountered in the analysis phase. For example multiple intermittent and non-steady noise sources were present during measurement (wind turbines car pass-bys wind in the trees human activities). Methods used to overcome these obstacles will be discussed (use of statistical parameters linear regression) and the effect of the wind turbine operation on the noise level (including low frequencies) and vibration level will be presented.

Long-term behaviour of baled household waste  

Science Journals Connector (OSTI)

This study was carried out at the laboratory scale (approximately 15 l) and using real baled waste of industrial dimensions (about 1 m3), in order to assess the long-term behaviour of baled household waste. The laboratory assays were carried out with real household waste which was fractioned on site, reconstituted in the laboratory and then compacted into 15 l airtight containers (unless stated otherwise). These containers were incubated under different experimental conditions at a constant temperature (28C). Three assays were conducted over 34 months and two others over 27 months. For the assays incubated in conditions simulating those of real baled waste (confined medium, with no aeration or water flow), a very low microbial activity was observed. The assay incubated in the same conditions but with slight aeration during the first three months in order to simulate imperfectly airtight wrapping, revealed biodegradation which started in a significant manner after 800 days of incubation. The evolution of two real wrapped bales each containing 900 kg of household waste was monitored over 8 months. These bales were produced industrially, one in July 97 and the other in July 98 at the incinerator plant at Agde (France). The bales were then stored outside at the laboratory location and their evolution was monitored mainly by biogas analysis and temperature measurement. No methane formation was observed, revealing the absence of anaerobic biodegradation, thus confirming the laboratory assays.

Long?term variations of ice breaking noise in Antarctica  

Science Journals Connector (OSTI)

Numerous low frequency transient signals arriving from Antarctica have been detected in five?year sea noise recordings in 2002?2006 at the hydroacoustic listening station deployed off Cape Leeuwin in Western Australia as part of the International Monitoring System of the Comprehensive Nuclear?Test?Ban Treaty. The majority of these signals consist of a single arrival of mode 1 which dominates the higher modes and undergoes strong frequency dispersion due to long?range propagation in the polar ocean environment. These signals are believed to be emitted primarily by ice rifting and breaking events on the Antarctic shelf. Several regions along the Antarctic coast associated with certain glaciers and ice tongues were found to persistently be much more active in generatingicenoise than other parts of the Antarctic shelf. An analysis of long?term changes in the frequency of occurrence of ice events showed noticeable seasonal cycles but did not reveal any significant interannual variations against the background of short?term fluctuations. Some of the ice events detected at the Cape Leeuwin station were also identified in sea noise recordings made on autonomous acoustic loggers deployed on the Antarctic shelf which allowed us to investigate characteristics of the acoustic signals from ice events near their origins.

Long-Term Assessment of Critical Radionuclides and Associated Environmental Media at the Savannah River Site - 13038  

SciTech Connect (OSTI)

During the operational history of the Savannah River Site (SRS), many different radionuclides have been released from site facilities. However, only a relatively small number of the released radionuclides have been significant contributors to doses and risks to the public. At SRS dose and risk assessments indicate tritium oxide in air and surface water, and Cs-137 in fish and deer have been, and continue to be, the critical radionuclides and pathways. In this assessment, statistical analyses of the long-term trends of tritium oxide in atmospheric and surface water releases and Cs-137 concentrations in fish and deer are provided. Correlations also are provided with 1) operational changes and improvements, 2) geopolitical events (Cold War cessation), and 3) recent environmental remediation projects and decommissioning of excess facilities. For example, environmental remediation of the F- and H-Area Seepage Basins and the Solid Waste Disposal Facility have resulted in a measurable impact on the tritium oxide flux to the onsite Fourmile Branch stream. Airborne releases of tritium oxide have been greatly affected by operational improvements and the end of the Cold War in 1991. However, the effects of SRS environmental remediation activities and ongoing tritium operations on tritium concentrations in the environment are measurable and documented in this assessment. Controlled hunts of deer and feral hogs are conducted at SRS for approximately six weeks each year. Before any harvested animal is released to a hunter, SRS personnel perform a field analysis for Cs-137 concentrations to ensure the Hunter's dose does not exceed the SRS administrative game limit of 0.22 milli-sievert (22 mrem). However, most of the Cs-137 found in SRS onsite deer is not from site operations but is from nuclear weapons testing fallout from the 1950's and early 1960's. This legacy source term is trended in the SRS deer, and an assessment of the 'effective' half-life of Cs-137 in deer (including the physical decay half-life and the environmental dispersion half-life) is provided. The 'creek mouth' fisherman is the next most critical pathway at SRS. On an annual basis, three species of fish (panfish, catfish, and bass) are sampled from the mouths of the five SRS streams. Three composites of up to five fish of each species are analyzed from each sampling location. Long-term trending of the Cs-137 concentrations in fish and the subsequent doses from consumption of SRS fish is provided. (authors)

Identification and correction of systematic error in NOAA AVHRR long-term satellite data record  

Science Journals Connector (OSTI)

Systematic error in long-term satellite data records resulting from inter-sensor differences or other persistent influences such as satellite orbital drift can greatly affect the use of these data to monitor land surface dynamics and trends. In this research an identification and correction procedure for systematic error is developed and used to evaluate the NOAA AVHRR long-term satellite data record produced by the Canada Center for Remote Sensing (CCRS). The record is composed of observations acquired by seven AVHRR sensors during the period 19852011. It includes two types of AVHRR sensor: AVHHR-2 flown onboard NOAA-9, -11, and ?14, and AVHRR-3 onboard NOAA-16, -17, -18 and ?19. Systematic error between sensors was identified through evaluation of synchronized nadir overpass (SNO) observations. The first order systematic error correction was derived from SNO comparison and then further optimized using a reference calibration target. Examination showed considerable difference between AVHRR-2 and AVHRR-3 measurements, which are largely attributed to differences in sensor design characteristics, uncertainty in sensor radiometric calibration, and imperfections in data processing. The results also show overall higher consistency between data from missions with AVHRR-3 than with AVHRR-2 sensors. The developed approach for correction of systematic error in time series was validated based on statistical analysis of eight independent pseudo-invariant targets not used for the initial correction development. Trends in these targets largely caused by the difference between AVHRR-2 and ?3 sensors are shown to be removed or reduced after the correction was applied.

PROTEC TM TEAR-OFFS: RESULTS OF LONG TERM TESTING  

SciTech Connect (OSTI)

The Savannah River National Laboratory (SRNL) has completed a series of tests (Phases 1 and 2) to assess the potential use of a Mylar{reg_sign} tear-off system as a primary or secondary protective barrier to minimize acid etching ('frosting'), accidental scratching, and/or radiation damage for shielded cells, glovebox, and/or chemical hood windows. Conceptually, thin, multi-layered sheets of Mylar (referred to throughout this report as the ProTec{trademark} tear-off system) can be directly applied to the shielded cell, glovebox, or hood sash window to serve as a secondary (or primary) barrier. Upon degradation of visual clarity due to accidental scratching, spills/splatters, and/or radiation damage, the outer layer (or sheet) of Mylar could be removed refreshing or restoring the view. Due to the multilayer aspect, the remaining Mylar layers would provide continued protection for the window from potential reoccurrences. Although the concept of using a tear-off system as a protective barrier is conceptually enticing, potential technical issues were identified and addressed as part of this phased study to support implementation of this type of system in the Defense Waste Processing Facility (DWPF). Specific test conditions of interest to the DWPF included the performance of the tear-off system exposed to or under the following conditions: (1) acid(s) (concentrated (28.9 M) HF, concentrated (15.9M) HNO{sub 3}, 6M HCl, and 0.6M H{sub 3}BO{sub 3}); (2) base (based on handling of radioactive sludges with pH of {approx}12-13); (3) gamma radiation (due to radioactive sources or materials being used in the analytical cells); (4) scratch resistance (simulating accidental scratching with the manipulators); and (5) in-situ testing (sample coupons exposed to actual field conditions in DWPF). The results of the Phase 1 study indicated that the ProTec tear-off concept (as a primary or secondary protective barrier) is a potential technical solution to prevent or retard excessive damage that would result from acid etching, base damage (as a result of a sludge spill or splatter), gamma radiation damage, and/or accidental scratching (due to manipulator/tool contact). Although identified as a potential solution, the Phase 1 testing was relatively short-term with exposure times up to 1-2 months for the acid and gamma radiation tests. Phase 2 testing included longer exposure times for the acid resistance (up to 456 days) and gamma radiation exposure (700 days with a cumulative gamma dose of {approx}3.1 x 10{sup 5} rad) assessments. The tear-off system continued to perform well in these longer-term acid resistance testing and gamma exposure conditions. Complete removal of the tear-offs after these long-term exposure times indicate that not only could visual clarity be restored but the mechanical integrity could be retained. The results also provided insight into the ability of the ProTec tear-off system to withstand the chemical and physical abuses expected in off-normal shielded cells operations. The conceptual erasing of scratches or marks by excessive manipulator abuse was demonstrated in the SRNL Shielded Cells mock-up facility through the removal of the outer layer tear-off with manipulators. In addition, the Phase 2 testing included an in-situ assessment of a prototype tear-off system in the DWPF Sampling Cells where the system was exposed to actual field conditions including radioactive sources, acidic and basic environments, dusting, and chemical cleaning solutions over a 5-6 month period. DWPF personnel were extremely satisfied with the performance (including the successful removal of 3 layers with manipulators) of the ProTec tear-off system under actual field conditions. The successful removal of the outer layer tear-offs with the manipulator, using tabs not specifically designed for remote operations, demonstrates that the system is 'manipulator-friendly' and could be implemented in a remote environment. The ability to remove the outer layer tear-off not only regains visual clarity but also reduces waste disposal volumes (i.e., dispo

Long-term surveillance plan for the Mexican Hat Disposal Site, Mexican Hat, Utah  

SciTech Connect (OSTI)

This plan describes the long-term surveillance activities for the Uranium Mill Tailings Remedial Action (UMTRA) Project disposal site at Mexican Hat, Utah. The U.S. Department of Energy (DOE) will carry out these activities to ensure that the disposal site continues to function as designed. This long-term surveillance plan (LTSP) was prepared as a requirement for acceptance under the U.S. Nuclear Regulatory Commission (NRC) general license for custody and long-term care of residual radioactive material (RRM). This LTSP (based on the DOE`s Guidance for Implementing the UMTRA Project Long-term Surveillance Program), documents the land ownership interests and details how the long-term care of the disposal site will be accomplished.

Long-term decontamination engineering study. Volume 1  

SciTech Connect (OSTI)

This report was prepared by Westinghouse Hanford Company (WHC) with technical and cost estimating support from Pacific Northwest Laboratories (PNL) and Parsons Environmental Services, Inc. (Parsons). This engineering study evaluates the requirements and alternatives for decontamination/treatment of contaminated equipment at the Hanford Site. The purpose of this study is to determine the decontamination/treatment strategy that best supports the Hanford Site environmental restoration mission. It describes the potential waste streams requiring treatment or decontamination, develops the alternatives under consideration establishes the criteria for comparison, evaluates the alternatives, and draws conclusions (i.e., the optimum strategy for decontamination). Although two primary alternatives are discussed, this study does identify other alternatives that may warrant additional study. hanford Site solid waste management program activities include storage, special processing, decontamination/treatment, and disposal facilities. This study focuses on the decontamination/treatment processes (e.g., waste decontamination, size reduction, immobilization, and packaging) that support the environmental restoration mission at the Hanford Site.

Long-term Industrial Energy Forecasting (LIEF) model (18-sector version)  

SciTech Connect (OSTI)

The new 18-sector Long-term Industrial Energy Forecasting (LIEF) model is designed for convenient study of future industrial energy consumption, taking into account the composition of production, energy prices, and certain kinds of policy initiatives. Electricity and aggregate fossil fuels are modeled. Changes in energy intensity in each sector are driven by autonomous technological improvement (price-independent trend), the opportunity for energy-price-sensitive improvements, energy price expectations, and investment behavior. Although this decision-making framework involves more variables than the simplest econometric models, it enables direct comparison of an econometric approach with conservation supply curves from detailed engineering analysis. It also permits explicit consideration of a variety of policy approaches other than price manipulation. The model is tested in terms of historical data for nine manufacturing sectors, and parameters are determined for forecasting purposes. Relatively uniform and satisfactory parameters are obtained from this analysis. In this report, LIEF is also applied to create base-case and demand-side management scenarios to briefly illustrate modeling procedures and outputs.

A Perspective on Long-Term Recovery Following the Fukushima Nuclear Accident - 12075  

SciTech Connect (OSTI)

The tragic events at the Fukushima Daiichi Nuclear Power Station began occurring on March 11, 2011, following Japan's unprecedented earthquake and tsunami. The subsequent loss of external power and on-site cooling capacity severely compromised the plant's safety systems, and subsequently, led to core melt in the affected reactors and damage to spent nuclear fuel in the storage pools. Together with hydrogen explosions, this resulted in a substantial release of radioactive material to the environment (mostly Iodine-131 and Cesium- 137), prompting an extensive evacuation effort. The latest release estimate places the event at the highest severity level (Level 7) on the International Nuclear Event Scale, the same as the Chernobyl accident of 1986. As the utility owner endeavored to stabilize the damaged facility, environmental contamination continued to propagate and affect every aspect of daily life in the affected region of Japan. Elevated levels of radioactivity (mostly dominated by Cs-137 with the passage of time) were found in soil, drinking water, vegetation, produce, seafood, and other foodstuffs. An estimated 80,000 to 90,000 people were evacuated; more evacuations are being contemplated months after the accident, and a vast amount of land has become contaminated. Early actions were taken to ban the shipment and sale of contaminated food and drinking water, followed by later actions to ban the shipment and sale of contaminated beef, mushrooms, and seafood. As the event continues to evolve toward stabilization, the long-term recovery effort needs to commence - a process that doubtless will involve rather complex decision-making interactions between various stakeholders. Key issues that may be encountered and considered in such a process include (1) socio-political factors, (2) local economic considerations, (3) land use options, (4) remediation approaches, (5) decontamination methods, (6) radioactive waste management, (7) cleanup levels and options, and (8) government policies, among others. This paper offers a perspective on this likely long and arduous journey toward establishing a 'new normal' that will ultimately take shape. Toward this end, it is important to evaluate the 'optimization' process advocated by the international community in achieving long-term recovery from this particularly fateful event in Fukushima. In the process, experience and lessons learned from past events will be fully evaluated and considered. (author)

Application of Improved Grey Model in Long-term Load Forecasting of Power Engineering  

Science Journals Connector (OSTI)

Grey model is usually been used for long-term load forecasting in power engineering, but it has significant limitations. If the moving average method and Markov model are connected with grey model, the accuracy of this improved grey model used for long-term load forecasting in power engineering can be effectively increased. In this paper, ordinary grey model and improved grey model are all chosen and used for long-term power load forecasting in power engineering, and the power load data of Qingdao in the past decade is selected for the analysis. The result of the analysis shows that the accuracy of improved grey model is significant higher than ordinary model, so the improved grey model can be used for long-term load forecasting in power engineering.

SciTech Connect (OSTI)

This long-term surveillance plan (LTSP) describes the U.S. Department of Energy`s (DOE) long-term care program for the Uranium Mill Tailings Remedial Action (UMTRA) Project Maybell disposal site in Moffat County, Colorado. The U.S. Nuclear Regulatory Commission (NRC) has developed regulations for the issuance of a general license for the custody and long-term care of UMTRA Project disposal sites in 10 CFR Part 40. The purpose of this general license is to ensure that the UMTRA Project disposal sites are cared for in a manner that protects the public health and safety and the environment. Before each disposal site is licensed, the NRC requires the DOE to submit a site-specific LTSP. The DOE prepared this LTSP to meet this requirement for the Maybell disposal site. The general license becomes effective when the NRC concurs with the DOE`s determination that remedial action is complete for the Maybell site and the NRC formally accepts this LTSP. This document describes the long-term surveillance program the DOE will implement to ensure the Maybell disposal site performs as designed. The program is based on site inspections to identify threats to disposal cell integrity. The LTSP is based on the UMTRA Project long-term surveillance program guidance document and meets the requirements of 10 CFR {section}40.27(b) and 40 CFR {section}192.03.

Long-term Analysis of Gear Loads in Fixed Offshore Wind Turbines Considering Ultimate Operational Loadings  

Science Journals Connector (OSTI)

Abstract The long-term extreme value analysis of gear transmitted load due to the main shaft torque is presented. Two methods, the multibody simulations (MBS) and a simplified method, are demonstrated for the gear transmitted load calculation. The simplified method is verified by the MBS results. The long-term extreme value of the gear transmitted load for wind speeds from the cut-in to the cut-out values is calculated by the simplified method from the long-term distribution of the main shaft torque. Three statistical methods for long-term extreme value analysis of the main shaft torque in the offshore wind turbines are presented. They are then used to predict the extreme value of the gear transmitted load. An alternative approach, the design state or the environmental contour method is proposed and verified by the full long-term results. The methods are exemplified by a 5 MW gearbox case study. The results of this paper are the basis for further work in Ultimate Limit State (ULS) gear design.

High Temperature Steam Electrolysis: Demonstration of Improved Long-Term Performance  

SciTech Connect (OSTI)

Long-term performance is an ongoing issue for hydrogen production based on high-temperature steam electrolysis (HTSE). For commercial deployment, solid-oxide electrolysis stacks must achieve high performance with long-term degradation rates of {approx}0.5%/1000 hours or lower. Significant progress has been achieved toward this goal over the past few years. This paper will provide details of progress achieved under the Idaho National Laboratory high temperature electrolysis research program. Recent long-term stack tests have achieved high initial performance with degradation rates less than 5%/khr. These tests utilize internally manifolded stacks with electrode-supported cells. The cell material sets are optimized for the electrolysis mode of operation. Details of the cells and stacks will be provided along with details of the test apparatus, procedures, and results.

Forward period analysis and the long term simulation of a periodic Hamiltonian system  

E-Print Network [OSTI]

The period of a Morse oscillator and mathematical pendulum system are obtained, accurate to 100 significant digits, by forward period analysis (FPA). From these results, the long-term [0, 10^60] (time unit) solutions, which overlap from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT) scheme. The application of FPA to periodic systems can reduce the computation loops of long-term reliable simulation from O(t^(1+1/M)) to O(lnt+t/h0) where T is the period, M the order and h0 a constant step-size. This scheme provides a way to generate reference solutions to test other schemes' long-term simulations.

Long-Term SOFC Stability with Coated Ferritic Stainless Steel Interconnect  

SciTech Connect (OSTI)

This study details long-term performance data for anode-supported thin-film YSZ-based SOFCs utilizing a ferritic stainless steel cathode current collector (Crofer22 APU) coated with a protective (Mn,Co)3O4 spinel to prevent Cr volatilization. Two standard cathode compositions, La(Sr)FeO3 and La(Sr)MnO3, were considered. The coating proved effective in blocking Cr migration, which resulted in long-term stability of the manganite cathode. In contrast the ferrite cathode indicated degradation that could not be attributed to Cr poisoning.

GPU-optimized Code for Long-term Simulations of Beam-beam Effects in Colliders  

SciTech Connect (OSTI)

We report on the development of the new code for long-term simulation of beam-beam effects in particle colliders. The underlying physical model relies on a matrix-based arbitrary-order symplectic particle tracking for beam transport and the Bassetti-Erskine approximation for beam-beam interaction. The computations are accelerated through a parallel implementation on a hybrid GPU/CPU platform. With the new code, a previously computationally prohibitive long-term simulations become tractable. We use the new code to model the proposed medium-energy electron-ion collider (MEIC) at Jefferson Lab.

Development of long-term performance models for radioactive waste forms  

SciTech Connect (OSTI)

The long-term performance of solid radioactive waste is measured by the release rate of radionuclides into the environment, which depends on corrosion or weathering rates of the solid waste form. The reactions involved depend on the characteristics of the solid matrix containing the radioactive waste, the radionuclides of interest, and their interaction with surrounding geologic materials. This chapter describes thermo-hydro-mechanical and reactive transport models related to the long-term performance of solid radioactive waste forms, including metal, ceramic, glass, steam reformer and cement. Future trends involving Monte-Carlo simulations and coupled/multi-scale process modeling are also discussed.

The Environment, Geopolitics and Artificial Islands of Dubai in the Persian Gulf  

Science Journals Connector (OSTI)

Abstract In recent decades, environmental degradation and its consequences as well as the importance of its safeguarding have resulted in the emergence of many researches in different scientific fields. However, the environmental geopolitics, as O Tuathail states, deals with the relationship between the earth and human in geopolitical tradition. Accordingly, in this paper, by adopting critical geopolitics perspective and through descriptive-analytical method, the environmental geopolitics in the Persian Gulf is studied. In this regard, the artificial islands of Dubai are considered the study cases. The facts suggest that these islands which are created as the result of developmental policies of Dubai, have threatened the environmental security of Persian Gulf and have caused alarming environmental consequences for other coastal states.

This LTSP documents that the land and interests are owned by the United States and details how long-term care of the disposal site will be carried out. It is based on the DOE`s Guidance for Implementing the UMTRA Project Long-term Surveillance Program (DOE, 1992a). Following the introduction, contents of this report include the following: site final condition; site drawings and photographs; permanent site surveillance features; ground water monitoring; annual site inspections; unscheduled inspections; custodial maintenance; corrective action; record keeping and reporting requirements; emergency notification and reporting; quality assurance; personal health and safety; list of contributions; and references.

SciTech Connect (OSTI)

This long-term surveillance plan (LTSP) describes the US Department of Energy`s (DOE) long-term care program for the Uranium Mill Tailings Remedial Action (UMTRA) Project South Clive disposal site in Clive, Utah. The US Nuclear Regulatory Commission (NRC) has developed regulations for the issuance of a general license for the custody and long-term care of UMTRA Project disposal sites in 10 CRF Part 40. The purpose of this general license is to ensure that the UMTRA Project disposal sites will be cared for in a manner that protects the public health and safety and the environment. For each disposal site to be licensed, the NRC requires the DOE to submit a site-specific LTSP. The DOE prepared this LTSP to meet this requirement for the South Clive disposal site. The general license becomes effective when the NRC concurs with the DOE`s determination of completion of remedial action for the South Clive site and the NRC formally accepts this LTSP. This LTSP describes the long-term surveillance program the DOE will implement to ensure that the South Clive disposal site performs as designed. The program`s primary activity is site inspections to identify threats to disposal cell integrity.

Abstract In a context of resource scarcity and political instability, new energy sources and technologies are being explored in many parts of the world and exploited in some. One of these new energy sources is shale gas and one of the countries seeking to decrease its energy dependence and increase its energy security is Poland which is largely dependent on gas and oil imports from Russia. This article presents the results of a thematic content analysis of articles reporting on shale gas/fracking published in Gazeta Wyborcza and Rzeczpospolita, two leading Polish newspapers, from 1 January 2010 to 31 December 2012. Findings suggest that in media reporting the geopolitical dimension of fracking overrides the technological/scientific dimension and that representations are overwhelmingly positive. Positive representations are bolstered through particular linguistic framings. It is argued that the Polish press has polarized the debate on fracking in a particular (positive) direction, which has silenced an open and constructive debate concerning energy policy in Poland and constructed criticism of fracking as counter-normative and un-Polish. The potential socio-political and policy implications of these media representations are discussed.

Innovative Strategy For Long Term Monitoring Of Metal And Radionuclide Plumes  

SciTech Connect (OSTI)

Many government and private industry sites that were once contaminated with radioactive and chemical wastes cannot be cleaned up enough to permit unrestricted human access. The sites will require long term management, in some cases indefinitely, leaving site owners with the challenge of protecting human health and environmental quality at these "legacy" sites. Long-term monitoring of groundwater contamination is one of the largest projected costs in the life cycle of environmental management at the Savannah River Site, the larger DOE complex, and many large federal and private sites. There is a need to optimize the performance and manage the cost of long term surveillance and monitoring at their sites. Currently, SRNL is initiating a pilot field test using alternative protocols for long term monitoring of metals and radionuclides. A key component of the approach is that monitoring efforts are focused on measurement of low cost metrics related to hydrologic and chemical conditions that control contaminant migration. The strategy combines careful monitoring of hydrologic boundary conditions with measurement of master variables such as chemical surrogates along with a smaller number of standard well analyses. In plumes contaminated with metals, master variables control the chemistry of the groundwater system, and include redox variables (ORP, DO, chemicals), pH, specific conductivity, biological community (breakdown/decay products), and temperature. Significant changes in these variables will result in conditions whereby the plume may not be stable and therefore can be used to predict possible plume migration. Conversely, concentration measurements for all types of contaminants in groundwater are a lagging indicator plume movement - major changes contaminant concentrations indicate that contamination has migrated. An approach based on measurement of master variables and explicit monitoring of hydrologic boundary conditions combined with traditional metrics should lead to improved monitoring while simultaneously reducing costs. This paradigm is being tested at the SRS F-Area where an innovative passive remedial system is being monitored and evaluated over the long term prior to traditional regulatory closure. Contaminants being addressed at this site are uranium, strontium-90, iodine-129, and tritium. We believe that the proposed strategies will be more effective in early identification of potential risks; these strategies will also be cost effective because controlling variables are relatively simple to measure. These variables also directly reflect the evolution of the plume through time, so that the monitoring strategy can be modified as the plume 'ages'. This transformational long-term monitoring paradigm will generate large cost savings to DOE, other federal agencies and industry and will provide improved performance and leading indicators of environmental management performance.

Long-Term DemonsTraTion of sorbenT Long-Term DemonsTraTion of sorbenT enhancemenT aDDiTive TechnoLogy for mercury conTroL Background The 2005 Clean Air Mercury Rule will require significant reductions in mercury emissions from coal-fired power plants. The combustion of subbituminous coals typically results in higher fractions of elemental mercury emissions than the combustion of bituminous coals. This complicates mercury capture efforts, particularly for technologies using powdered activated carbon (PAC) injection, because elemental mercury is not readily captured by PAC injection alone. In short, unmodified PACs are better suited for bituminous coals than for subbituminous coals. Various proprietary sorbent enhancement additives (SEA) have been developed to increase the mercury reactivity of PACs, and perhaps fly

Automobile technology, hydrogen and climate change: a long term modelling analysis  

Science Journals Connector (OSTI)

The transitions in the global automobile sector in the 21st century are uncertain both in terms of technologies and energy carriers. A key driving force of technological change in the long term could be the need to mitigate GHG emissions. This paper examines the role of the passenger car sector in a GHG mitigation strategy and presents a scenario of the automobile technology choices when a price on greenhouse gas emissions is imposed on the global energy system. The analysis has been conducted with ERIS, a multiregional energy systems, 'bottom up' optimisation model that endogenises technology learning and allows a detailed technology representation, in addition to capturing competing demands for transportation fuels, including hydrogen. Our results provide some policy insights by illustrating the potential for hydrogen to contribute to climate change mitigation, but show that fuel cell cars are an option for climate policy only over the very long term.

Summary of the engineering analysis report for the long-term management of depleted uranium hexafluoride  

SciTech Connect (OSTI)

The Department of Energy (DOE) is reviewing ideas for the long-term management and use of its depleted uranium hexafluoride. DOE owns about 560,000 metric tons (over a billion pounds) of depleted uranium hexafluoride. This material is contained in steel cylinders located in storage yards near Paducah, Kentucky; Portsmouth, Ohio; and at the East Tennessee Technology Park (formerly the K-25 Site) in Oak Ridge, Tennessee. On November 10, 1994, DOE announced its new Depleted Uranium Hexafluoride Management Program by issuing a Request for Recommendations and an Advance Notice of Intent in the Federal Register (59 FR 56324 and 56325). The first part of this program consists of engineering, costs and environmental impact studies. Part one will conclude with the selection of a long-term management plan or strategy. Part two will carry out the selected strategy.

The liquid and solid residues continue to be a concern at Rocky Flats, primarily due to safety aspects of long-term storage and of the need for processing them into a form for ultimate disposal. Currently, Rocky Flats is processing the low-level solutions from bottles and tanks by direct cementation for storage and disposal. Plans for actinide precipitation of the high-level solutions are being finalized with an anticipated completion date of 2 to 3 yr. The solid residues present a more difficult challenge because of the numerous forms that these exist. Rocky Flats is developing several strategies to handle these materials for safe long-term storage and eventual disposal.

Long-term Kinetics of Uranyl Desorption from Sediments Under Advective Conditions  

SciTech Connect (OSTI)

Long-term (> 4 months) column experiments were performed to investigate the kinetics of uranyl (U(VI)) desorption in sediments collected from the Integrated Field Research Challenge (IFRC) site at the US Department of Energy (DOE) Hanford 300 Area. The experimental results were used to evaluate alternative multi-rate surface complexation reaction (SCR) approaches to describe the short- and long-term kinetics of U(VI) desorption under flow conditions. The SCR stoichiometry, equilibrium constants, and multi-rate parameters were independently characterized in batch and stirred flow-cell reactors. Multi-rate SCR models that were either additively constructed using the SCRs for individual size fractions (e.g., Shang et al., 2011), or composite in nature could effectively describe short-term U(VI) desorption under flow conditions. The long-term desorption results, however, revealed that using a labile U concentration measured by carbonate extraction under-estimated desorbable U(VI) and the long-term rate of U(VI) desorption. An alternative modeling approach using total U as the desorbable U(VI) concentration was proposed to overcome this difficulty. This study also found that the gravel size fraction (2-8 mm), which is typically treated as non-reactive in modeling U(VI) reactive transport because of low external surface area, can have an important effect on the U(VI) desorption in the sediment. This study demonstrates an approach to effectively extrapolate U(VI) desorption kinetics for field-scale application, and identifies important parameters and uncertainties affecting model predictions.

SNAP-25 is expressed not only in the CA1 region, but also in the CA3 region, and the SNAP-25 mRNA level in the CA3 region is higher than in the CA1 region. Here, we provide evidence that SNAP-25 in the CA3 region is also involved in learning/memory. Intra-CA3 infusion of SNAP-25 antisense oligonucleotide impaired both long-term contextual fear memory and water-maze spatial memory, with short-term memory intact. Furthermore, the SNAP-25 antisense oligonucleotide suppressed the long-term potentiation (LTP) of field excitatory post-synaptic potential (fEPSP) in the mossy-fiber pathway (DG-CA3 pathway), with no effect on paired-pulse facilitation of the fEPSP. These results are consistent with the notion that SNAP-25 in the hippocampal CA3 region is required for long-term memory formation.

Local Government Implementation of Long-Term Stewardship at Two DOE Facilities  

SciTech Connect (OSTI)

The Department of Energy (DOE) is responsible for cleaning up the radioactive and chemical contamination that resulted from the production of nuclear weapons. At more than one hundred sites throughout the country DOE will leave some contamination in place after the cleanup is complete. In order to protect human health and the environment from the remaining contamination DOE, U.S. Environmental Protection Agency (EPA), state environmental regulatory agencies, local governments, citizens and other entities will need to undertake long-term stewardship of such sites. Long-term stewardship includes a wide range of actions needed to protect human health in the environment for as long as the risk from the contamination remains above acceptable levels, such as barriers, caps, and other engineering controls and land use controls, signs, notices, records, and other institutional controls. In this report the Environmental Law Institute (ELI) and the Energy Communities Alliance (ECA) examine how local governments, state environmental agencies, and real property professionals implement long-term stewardship at two DOE facilities, Losa Alamos National Laboratory and Oak Ridge Reservation.

Long-term spectroscopic monitoring of the Luminous Blue Variable HD160529  

E-Print Network [OSTI]

We have spectroscopically monitored the galactic Luminous Blue Variable HD 160529 and obtained an extensive high-resolution data set that covers the years 1991 to 2002. During this period, the star evolved from an extended photometric minimum phase towards a new visual maximum. In several observing seasons, we covered up to four months with almost daily spectra. Our spectra typically cover most of the visual spectral range with a high spectral resolution (about 20,000 or more). This allows us to investigate the variability in many lines and on many time scales from days to years. We find a correlation between the photospheric HeI lines and the brightness of the star, both on a time scale of months and on a time scale of years. The short-term variations are smaller and do not follow the long-term trend, strongly suggesting different physical mechanisms. Metal lines also show both short-term and long-term variations in strength and also a long-term trend in radial velocity. Most of the line-profile variations can be attributed to changing strengths of lines. Propagating features in the line profiles are rarely observed. We find that the mass-loss rate of HD 160529 is almost independent of temperature, i.e. visual brightness.

Shifting the Paradigm for Long Term Monitoring at Legacy Sites to Improve Performance while Reducing Cost  

SciTech Connect (OSTI)

A major issue facing many government and private industry sites that were previously contaminated with radioactive and chemical wastes is that often the sites cannot be cleaned up enough to permit unrestricted human access. These sites will require long-term management, in some cases indefinitely, leaving site owners with the challenge of protecting human health and environmental quality in a cost effective manner. Long-term monitoring of groundwater contamination is one of the largest projected costs in the life cycle of environmental management at the Savannah River Site (SRS), the larger DOE complex, and many large federal and private sites. Currently, most monitoring strategies are focused on laboratory measurements of contaminants measured in groundwater samples collected from wells. This approach is expensive, and provides limited and lagging information about the effectiveness of cleanup activities and the behavior of the residual contamination. Over the last twenty years, DOE and other federal agencies have made significant investments in the development of various types of sensors and strategies that would allow for remote analysis of contaminants in groundwater, but these approaches do not promise significant reductions in risk or cost. Scientists at SRS have developed a new paradigm to simultaneously improve the performance of long term monitoring systems while lowering the overall cost of monitoring. This alternative approach incorporates traditional point measurements of contaminant concentration with measurements of controlling variables including boundary conditions, master variables, and traditional plume/contaminant variables. Boundary conditions are the overall driving forces that control plume movement and therefore provide leading indication to changes in plume stability. These variables include metrics associated with meteorology, hydrology, hydrogeology, and land use. Master variables are the key variables that control the chemistry of the groundwater system, and include redox variables (ORP, DO, chemicals), pH, specific conductivity, biological community (breakdown/decay products), and temperature. A robust suite of relatively inexpensive tools is commercially available to measure these variables. Traditional plume/contaminant variables are various measures of contaminant concentration including traditional analysis of chemicals in groundwater samples. An innovative long term monitoring strategy has been developed for acidic or caustic groundwater plumes contaminated with metals and/or radionuclides. Not only should the proposed strategy be more effective at early identification of potential risks, this strategy should be significantly more cost effective because measurement of controlling boundary conditions and master variables is relatively simple. These variables also directly reflect the evolution of the plume through time, so that the monitoring strategy can be modified as the plume 'ages'. This transformational long-term monitoring paradigm will generate significant cost savings to DOE, other federal agencies and industry and will provide improved performance and leading indicators of environmental management performance.

2009 DOE-EM LONG-TERM MONITORING TECHNICAL FORUM SUMMARY REPORT  

SciTech Connect (OSTI)

The U. S. Department of Energy's (DOE) Office of Environmental Management (EM) has the responsibility for cleaning up 60 sites in 22 states that were associated with the legacy of the nation's nuclear weapons program and other research and development activities. These sites are unique and many of the technologies needed to successfully disposition the associated wastes have yet to be developed or would require significant re-engineering to be adapted for future EM cleanup efforts. In 2008, the DOE-EM Engineering and Technology Program (EM-22) released the Engineering and Technology Roadmap in response to Congressional direction and the need to focus on longer term activities required for the completion of the aforementioned cleanup program. One of the strategic initiatives included in the Roadmap was to enhance long term performance monitoring as defined by 'Develop and deploy cost effective long-term strategies and technologies to monitor closure sites (including soil, groundwater, and surface water) with multiple contaminants (organics, metals and radionuclides) to verify integrated long-term cleanup performance'. To support this long-term monitoring (LTM) strategic initiative, EM 22 and the Savannah River National Laboratory (SRNL) organized and held an interactive symposia, known as the 2009 DOE-EM Long-Term Monitoring Technical Forum, to define and prioritize LTM improvement strategies and products that could be realized within a 3 to 5 year investment time frame. This near-term focus on fundamental research would then be used as a foundation for development of applied programs to improve the closure and long-term performance of EM's legacy waste sites. The Technical Forum was held in Atlanta, GA on February 11-12, 2009, and attended by 57 professionals with a focus on identifying those areas of opportunity that would most effectively advance the transition of the current practices to a more effective strategy for the LTM paradigm. The meeting format encompassed three break-out sessions, which focused on needs and opportunities associated with the following LTM technical areas: (1) Performance Monitoring Tools, (2) Systems, and (3) Information Management. The specific objectives of the Technical Forum were to identify: (1) technical targets for reducing EM costs for life-cycle monitoring; (2) cost-effective approaches and tools to support the transition from active to passive remedies at EM waste sites; and (3) specific goals and objectives associated with the lifecycle monitoring initiatives outlined within the Roadmap. The first Breakout Session on LTM performance measurement tools focused on the integration and improvement of LTM performance measurement and monitoring tools that deal with parameters such as ecosystems, boundary conditions, geophysics, remote sensing, biomarkers, ecological indicators and other types of data used in LTM configurations. Although specific tools were discussed, it was recognized that the Breakout Session could not comprehensively discuss all monitoring technologies in the time provided. Attendees provided key references where other organizations have assessed monitoring tools. Three investment sectors were developed in this Breakout Session. The second Breakout Session was on LTM systems. The focus of this session was to identify new and inventive LTM systems addressing the framework for interactive parameters such as infrastructure, sensors, diagnostic features, field screening tools, state of the art characterization monitoring systems/concepts, and ecosystem approaches to site conditions and evolution. LTM systems consist of the combination of data acquisition and management efforts, data processing and analysis efforts and reporting tools. The objective of the LTM systems workgroup was to provide a vision and path towards novel and innovative LTM systems, which should be able to provide relevant, actionable information on system performance in a cost-effective manner. Two investment sectors were developed in this Breakout Session. The last Breakout Session of the Technical Forum

Long-term Results of Endovascular Stent Graft Placement of Ureteroarterial Fistula  

SciTech Connect (OSTI)

PurposeTo evaluate the safety, efficacy, and long-term results of endovascular stent graft placement for ureteroarterial fistula (UAF).MethodsWe retrospectively analyzed stent graft placement for UAF performed at our institution from 2004 to 2012. Fistula location was assessed by contrast-enhanced computed tomography (CT) and angiography, and freedom from hematuria recurrence and mortality rates were estimated.ResultsStent graft placement for 11 UAFs was performed (4 men, mean age 72.8 {+-} 11.6 years). Some risk factors were present, including long-term ureteral stenting in 10 (91 %), pelvic surgery in 8 (73 %), and pelvic radiation in 5 (45 %). Contrast-enhanced CT and/or angiography revealed fistula or encasement of the artery in 6 cases (55 %). In the remaining 5 (45 %), angiography revealed no abnormality, and the suspected fistula site was at the crossing area between urinary tract and artery. All procedures were successful. However, one patient died of urosepsis 37 days after the procedure. At a mean follow-up of 548 (range 35-1,386) days, 4 patients (36 %) had recurrent hematuria, and two of them underwent additional treatment with secondary stent graft placement and surgical reconstruction. The hematuria recurrence-free rates at 1 and 2 years were 76.2 and 40.6 %, respectively. The freedom from UAF-related and overall mortality rates at 2 years were 85.7 and 54.9 %, respectively.ConclusionEndovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.

GOLDSIM models of long-term radiation impact of conditionally cleared radioactive material  

Science Journals Connector (OSTI)

Abstract Management of waste materials from the decommissioning of nuclear installations offers opportunities for optimization. Large amounts of waste materials with low contents of various radionuclides could be recycled to save financial resources or repository capacity. The increase of the share of recycled materials compared to the current practice could be accomplished by applying the conditional clearance concept. Conditional clearance, as up to now is an unproven theoretical concept, demands utilization of the cleared material for the previously defined purpose (e.g., building construction). Safety studies needed for realization of this practice have to prove that conditionally cleared material will not cause radiation impact exceeding levels prescribed in health and safety regulations. Safety studies assess radiation impact during all manipulations with low level radioactive material (e.g., melting, component manufacturing, building of construction, etc.) as well as its impact on inhabitants living near the construction built using conditionally cleared material. The article is focused on modeling and calculation of long-term radiation impact on inhabitants living near the constructions. Models (scenarios) of various building applications were simulated using GOLDSIM software with Radionuclide Transport Module. Scenarios were selected according to information from the civil engineering business to cover the types of buildings most suitable for application of conditionally cleared material. The results of the calculations showed that conditional clearance represents no significant safety issue in the long-term. Calculated individual effective doses received by inhabitants did not exceed the given dose constraint (10?Sv/year) in case of any scenario evaluated. Detailed and transparent studies of the long-term impact of conditionally cleared materials are important especially for winning of public acceptance.

SHORT AND LONG-TERM FIRE IMPACTS ON HANFORD BARRIER PERFORMANCE  

SciTech Connect (OSTI)

A critical unknown in long-term engineered barrier use is the post-fire hydrologic function where institutional controls are in-tact but there are no resources to implement maintenance activities such as re-planting. This objective of this study was to simulate wild fire on an engineered barrier at the Hanford Site and document the post-fire changes in barrier performance. Soil physical, chemical, and hydrologic conditions; plant floristics and density; and animal use were characterized pre- and post-burn. Fuel load on the surface ranged from 4.7 to 5.71 tons/acre. Fire was initiated by drip torch and measurements of flame height and temperature were made at nine locations on the barrier surface. Flame heights exceeded 30 ft and temperatures ranged from 250 C at 1.5 cm below the surface to over 700 C at 1 m above the surface. Soil organic matter, soil wettability, and hydraulic conductivity all decreased significantly relative to pre-fire conditions. Post-fire samples showed an increase in major soil nutrients, pH, and electrical conductivity measured in 1:1 extracts whereas organic matter decreased. Decreases in wettabilty and organic matter are indicative of conditions more conducive to runoff and soil loss. The results of this study will contribute to a better understanding of post-fire recovery in a post-institutional control environment. This should lead to enhanced stakeholder acceptance regarding the long-term efficacy of ET barriers. This study will also support improvements in the design of ET barriers and performance monitoring systems. Such improvements are needed to best meet the long-term commitment to the safe in-place isolation of waste for hundreds if not thousands of years.

Analytical frameworks to incorporate demand response in long-term resource planning  

Science Journals Connector (OSTI)

Abstract Many utilities are obligated by state regulatory or legislative requirements to consider demand response (DR) as part of their resource planning process. There are several ways to incorporate DR into resource planning modeling and each has its advantages and disadvantages. We explore the current analytical frameworks for incorporating DR into long-term resource planning. We also consider whether current approaches accurately and realistically model DR resources in capacity expansion and production cost models and whether barriers exist to incorporating DR into resource planning models in a more robust fashion. We identify 10 specific recommendations for enhancing and expanding the current approaches.

A hybrid measure-correlate-predict method for long-term wind condition assessment  

Science Journals Connector (OSTI)

Abstract This paper develops a hybrid measure-correlate-predict (MCP) strategy to assess long-term wind resource variations at a farm site. The hybrid MCP method uses recorded data from multiple reference stations to estimate long-term wind conditions at a target wind plant site with greater accuracy than is possible with data from a single reference station. The weight of each reference station in the hybrid strategy is determined by the (i) distance and (ii) elevation differences between the target farm site and each reference station. In this case, the wind data is divided into sectors according to the wind direction, and the MCP strategy is implemented for each wind direction sector separately. The applicability of the proposed hybrid strategy is investigated using five MCP methods: (i) the linear regression; (ii) the variance ratio; (iii) the Weibull scale; (iv) the artificial neural networks; and (v) the support vector regression. To implement the hybrid MCP methodology, we use hourly averaged wind data recorded at five stations in the state of Minnesota between 07-01-1996 and 06-30-2004. Three sets of performance metrics are used to evaluate the hybrid MCP method. The first set of metrics analyze the statistical performance, including the mean wind speed, wind speed variance, root mean square error, and mean absolute error. The second set of metrics evaluate the distribution of long-term wind speed; to this end, the Weibull distribution and the Multivariate and Multimodal Wind Distribution models are adopted. The third set of metrics analyze the energy production of a wind farm. The best hybrid MCP strategy from 256 different combinations of MCP algorithms and reference stations is investigated and selected. The results illustrate that the many-to-one correlation in such a hybrid approach can provide a more reliable prediction of long-term on-site wind variations than that provided by the one-to-one correlations. The accuracy of the hybrid MCP method is found to be highly sensitive to the combination of individual MCP algorithms and reference stations used. It is also observed that the best combination of MCP algorithms is influenced by the length of the concurrent short-term correlation period.

Semi-passive, Chemical Oxidation Schemes for the Long-term Treatment of Contaminants  

SciTech Connect (OSTI)

This research involves a combined experimental and modeling study that builds on our previous DOE-sponsored work in investigating how KMnO{sub 4} can be better used with in situ remediation of groundwater contaminated by chlorinated ethylenes (e.g., PCE, TCE, DCE). This study aims to provide scientific basis for developing a new long-term, semi-passive ISCO scheme that uses controlled release KMnO{sub 4} as a reactive barrier component. Specific objectives of the study are (1) to construct controlled release KMnO{sub 4} as a new reactive barrier component that could deliver permanganate at a controlled rate over long time periods of years, (2) to quantitatively describe release mechanisms associated with the controlled release KMnO{sub 4}, (3) to demonstrate efficacy of the new remediation scheme using proof-of-concept experiments, and (4) to design advanced forms of controlled release systems through numerical optimization. The new scheme operates in a long-term, semi-passive manner to control spreading of a dissolved contaminant plume with periodic replacement of the controlled release KMnO{sub 4} installed in the subsurface. As a first step in developing this remedial concept, we manufactured various prototype controlled release KMnO{sub 4} forms. Then we demonstrated using column experiments that the controlled release KMnO{sub 4} could deliver small amount of permanganate into flowing water at controlled rates over long time periods of years. An analytical model was also used to estimate the diffusivities and durations of the controlled release KMnO{sub 4}. Finally, proof-of-concept flow-tank experiments were performed to demonstrate the efficacy of the controlled release KMnO{sub 4} scheme in controlling dissolved TCE plume in a long-term, semi-passive manner. Another important thrust of our research effort involved numerical optimization of controlled release systems. This study used a numerical model that is capable of describing release patterns of active agent from controlled release systems of varied forms and applications. We manufactured prototype single- and double-layered matrix-type controlled release systems and tested their release patterns using numerical simulations and column experiments. In a series of simulations, we demonstrated that an encapsulated, dispersed-agent polymeric matrix-type controlled release system could deliver active agent at a predetermined constant rate for long time periods of years and decades. Such long-term, constant release system is useful in the construction of fertilizers, herbicides, or implantable drug delivery devices as well as in subsurface treatment. Construction of more advanced forms of controlled release systems is currently under way.

Very long term communication intelligence: The case of markers for nuclear waste sites  

Science Journals Connector (OSTI)

Warning markers for long-term nuclear waste storage sites are required to prevent inadvertent human intrusion in the distant future. Two interdisciplinary teams have addressed the issues of physical durability and cognitive intelligibility of such markers for a U.S. government site in New Mexico. Preliminary design criteria have determined which materials are best suited to constitute markers of different sizes and shapes. A variety of linguistic, symbolic, and pictographic approaches to content have been suggested. Additional study and testing of both materials and messages is required. International standardization of marker strategies is extremely desirable.

The long-term problems of contaminated land: Sources, impacts and countermeasures  

SciTech Connect (OSTI)

This report examines the various sources of radiological land contamination; its extent; its impacts on man, agriculture, and the environment; countermeasures for mitigating exposures; radiological standards; alternatives for achieving land decontamination and cleanup; and possible alternatives for utilizing the land. The major potential sources of extensive long-term land contamination with radionuclides, in order of decreasing extent, are nuclear war, detonation of a single nuclear weapon (e.g., a terrorist act), serious reactor accidents, and nonfission nuclear weapons accidents that disperse the nuclear fuels (termed ''broken arrows'').

A PASSIVE SOLAR HEATING SYSTEM COMBINED WITH A HEATPUMP AND A LONG TERM HEAT STORAGE  

Science Journals Connector (OSTI)

ABSTRACT This paper describes the design and the first preliminary performance results of a sunspace attached to an existent building, combined with a heatpump and a long term heat storage. The aim of the project is to study the possibility of storing the excess heat of the passive system in a low temperature storage, which is used as cold source for a heatpump. The advantages of the presented system are that the energy flows in the passive solar system can be controlled and that a rather high solar fraction can be obtained (around .7 to .8 in the climate of Ispra).

CANE FIBERBOARD DEGRADATION WITHIN THE 9975 SHIPPING PACKAGE DURING LONG-TERM STORAGE APPLICATION  

SciTech Connect (OSTI)

The 9975 shipping package is used as part of the configuration for long-term storage of special nuclear materials in the K Area Complex at the Savannah River Site. The cane fiberboard overpack in the 9975 package provides thermal insulation, impact absorption and criticality control functions relevant to this application. The Savannah River National Laboratory has conducted physical, mechanical and thermal tests on aged fiberboard samples to identify degradation rates and support the development of aging models and service life predictions in a storage environment. This paper reviews the data generated to date, and preliminary models describing degradation rates of cane fiberboard in elevated temperature elevated humidity environments.

Long-term surveillance plan for the Canonsburg, Pennsylvania, disposal site  

SciTech Connect (OSTI)

This document establishes elements of the US Department of Energy`s (DOE) Long-Term Surveillance Plan for the Canonsburg, Pennsylvania, disposal site. The US Nuclear Regulatory Commission (NRC) will use this plan in support of license issuance for the long-term surveillance of the Canonsburg site. The Canonsburg (CAN) site is located within the borough of Canonsburg, Washington County, in southwestern Pennsylvania. The Canonsburg site covers approximately 30 acres (74 hectares). The disposal cell contains approximately 226,000 tons (241,000 tons) of residual radioactive material (RRM). Area C is southeast of the Canonsburg site, between Strabane Avenue and Chartiers Creek. Contaminated soils were removed from Area C during the remedial action, and the area was restored with uncontaminated fill material.After this cleanup, residual quantities of thorium-230 were detected at several Area C locations. The remedial action plan did not consider the ingrowth of radium-226 from thorium-230 as part of the Area C cleanup, and only two locations contained sufficient thorium-230 concentrations to result in radium-226 concentrations slightly above the US Environmental Protection Agency (EPA) standards.

Long-term corrosion measurements in condensing heat exchangers. Topical report, September 1989-January 1993  

SciTech Connect (OSTI)

Corrosion of metals used in condensing heat exchangers for gas appliances has been correlated most strongly with the chloride content of the condensate. This study presents results of an experimental examination of the long-term corrosion in metals used in condensing heat exchangers. The objective of this work is to develop a rationale for predicting the performance and expected service life of metals in condensing heat exchangers. Long-term exposure tests were conducted using finned-tube condensing heat exchangers containing tubes of 304L, 3161L, 3171L, Sea-Cure, and 29-4C steel, and aluminum. The natural gas was spiked with R-11 to generate chloride ion levels in the condensate of 3 ppm, 26 ppm, and 225 ppm. The aluminum tubes experienced through-the-wall pitting after 1.5 months at 225 ppm chloride, and after 6 months at 26 ppm chloride. At 3 ppm, most of the tubes exhibited no corrosion. At 225 ppm and 26 ppm, the 300-series stainless steels experienced through-the-wall corrosion within 3 months, but at 3 ppm virtually no corrosion was found. Sea-Cure and 29-4C exhibited the best corrosion resistance with some pitting at 225 ppm but none at 26 ppm and 3 ppm.

Effect of interconnect creep on long-term performance of SOFC of one cell stacks  

SciTech Connect (OSTI)

Creep deformation becomes relevant for a material when the operating temperature is near or exceeds half of its melting temperature (in degrees of Kelvin). The operating temperatures for most of the solid oxide fuel cells (SOFC) under development in the SECA program are around 1073oK. High temperature ferritic alloys are potential candidates as interconnect (IC) materials and spacers due to their low cost and CTE compatibility with other SOFC components. Since the melting temperature of most stainless steel is around 1800oK, possible creep deformation of IC under the typical cell operating temperature should not be neglected. In this paper, the effects of interconnect creep behavior on stack geometry change and stress redistribution of different cell components are predicted and summarized. The goal of the study is to investigate the performance of the fuel cell stack by obtaining the fuel and air channel geometry changes due to creep of the ferritic stainless steel interconnect, therefore indicating possible SOFC performance change under long term operations. IC creep models were incorporated into SOFC-MP and Mentat FC, and finite element analyses were performed to quantify the deformed configuration of the SOFC stack under the long term steady state operating temperature. It is found that creep behavior of the ferritic stainless steel IC contributes to narrowing of both the fuel and the air flow channels. In addition, stress re-distribution of the cell components suggests the need for a compliant sealing material that also relaxes at operating temperature.

National Nuclear Security Administration Service Center Environmental Programs Long-Term Environmental Stewardship Baseline Handbook  

SciTech Connect (OSTI)

As environmental restoration (ER) projects move toward completion, the planning, integration, and documentation of long-term environmental stewardship (LTES) activities is increasingly important for ensuring smooth transition to LTES. The Long-Term Environmental Stewardship Baseline Handbook (Handbook) prepared by the National Nuclear Security Administration (NNSA) Service Center Environmental Programs Department (EPD) outlines approaches for integrating site-specific LTES planning and implementation into site ER baseline documentation. Since LTES will vary greatly from site to site, the Handbook also provides for flexibility in addressing LTES in ER Project life-cycle baselines, while clearly identifying Environmental Management (EM) requirements. It provides suggestions for enacting LTES principles and objectives through operational activities described in site-specific LTES plans and life cycle ER Project baseline scope, cost, and schedule documentation and tools for more thorough planning, better quantification, broader understanding of risk and risk management factors, and more comprehensive documentation. LTES planning applied to baselines in a phased approach will facilitate seamlessly integrating LTES into site operational activities, thereby minimizing the use of resources.

Long-term persistence of pioneer species in tropical forest soil seed banks  

SciTech Connect (OSTI)

In tropical forests, pioneer species regenerate from seeds dispersed directly into canopy gaps, and from seeds that persisted in soil seed banks before gap formation. However, life-history models suggest that selection for long-term persistence of seeds in soil should be weak, as persistence incurs a fitness cost resulting from prolonged generation time. We use a carbon dating technique to provide the first direct measurements of seed persistence in undisturbed tropical forest seed banks. We show that seeds germinate successfully from surface soil microsites up to 38 years after dispersal. Decades-long persistence may be common in pioneers with relatively large mass, and appears to be unrelated to specific regeneration requirements. In Croton billbergianus, a sub-canopy tree that recruits in abundant small gaps, long-term persistence is associated with short-distance ballistic seed dispersal. In Trema micrantha, a canopy tree with widespread dispersal, persistence is associated with a requirement for large gaps that form infrequently in old-growth forest.

Long-Term Global Trade-Offs Related to Nuclear Energy  

SciTech Connect (OSTI)

An overall comparative assessment of different energy systems and their potential long-term role in contributing to a sustainable energy mix is examined through the use of a global, long-term Energy, Economics, Environment (E{sup 3}) model. This model is used to generate a set of surprise-free futures that encompass a range of economic potentialities. The focus of this study is nuclear energy (NE), and the range of possible futures embodies extrema of NE growth [a Basic Option (BO)] to an NE Phase Out (PO). These NE scenario extrema are expressed against a background that reflects E{sup 3} circumstances ranging from a Business-As-Usual (BAU) to one that is Ecologically Driven (ED), with the latter emphasizing price-induced reductions in greenhouse-gas (GHG) emissions associate with a mix of fossil energy sources. Hence, four ''views-of-the-future'' scenarios emerge to form the framework of this study: BAU/BO, BAU/PO, ED/BO, and ED/PO. Model results ranging from (regional and temporal) primary- and nuclear-energy demands, carbon-dioxide emissions, nuclear-material (plutonium) accumulations and attendant proliferation-risk implications, Gross National Product (GNP) impacts, and a range of technology requirements provide essential input to the subject assessment.

Ultrahigh Sensitivity Heavy Noble Gas Detectors for Long-Term Monitoring and for Monitoring Air  

SciTech Connect (OSTI)

The primary objective of this research project is to develop heavy noble gas (krypton, xenon, and radon) detectors for (1) long-term monitoring of transuranic waste, spent fuel, and other uranium and thorium bearing wastes and (2) alpha particle air monitors that discriminate between radon emissions and other alpha emitters. A University of Cincinnati/Argonne National Laboratory (UC/ANL) Team was assembled to complete this detector development project. Effective 1/4/99, the UC PI (John Valentine) became an Associate Professor in the Nuclear and Radiological Engineering Program of the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. Consequently, this project was transferred to Georgia Tech (GT) with the PI. UC funding extended to 1/31/99 and GT funding became active 4/26/99. Due to this transfer, we will refer to the research team as the GT/UC/ANL Team for this Annual Report. Subsequently, we will use GT/ANL Team. DOE needs that are ad dressed by this project include improved long-term monitoring capability and improved air monitoring capability during remedial activities. Successful development and implementation of the proposed detection systems could significantly improve current capabilities with relatively simple and inexpensive equipment.

Effects of long-term elevated atmospheric CO{sub 2} concentrations on Pinus ponderosa  

SciTech Connect (OSTI)

This report details the results from an experiment of the effects of long-term elevated atmospheric CO{sub 2} concentrations on ponderosa pine (Pinus ponderosa Laws.) saplings and seedlings. The study began in 1983 as a pilot study designed to explore the feasibility of using open-top chambers for continuous multi-year exposures on sapling-sized trees and to examine possible CO{sub 2} responses so that future research could be adequately designed. however, following the first year of exposure, preliminary results from the study indicated that measurements of CO{sub 2} responses should be intensified. Open-top chambers proved suitable for use in multiyear exposures of mature trees. With respect to the preliminary examination of CO{sub 2} responses, many interesting observations were made. The nature of the preliminary results suggests that future long-term field CO{sub 2} exposures on perennial species may be critical to the understanding and preparation for future environments. Other research reported here attempted to adapt an existing western coniferous forest growth and succession model for use in elevated CO{sub 2} scenarios using differential species responses, and assessed the usefulness of the model in that regard. Seven papers have been processed separately for inclusion in the appropriate data bases.

Test Plan for Long-Term Operation of a Ten-Cell High Temperature Electrolysis Stack  

SciTech Connect (OSTI)

This document defines a test plan for a long-term (2500 Hour) test of a ten-cell high-temperature electrolysis stack to be performed at INL during FY09 under the Nuclear Hydrogen Initiative. This test was originally planned for FY08, but was removed from our work scope as a result of the severe budget cuts in the FY08 NHI Program. The purpose of this test is to evaluate stack performance degradation over a relatively long time period and to attempt to identify some of the degradation mechanisms via post-test examination. This test will be performed using a planar ten-cell Ceramatec stack, with each cell having dimensions of 10 cm 10 cm. The specific makeup of the stack will be based on the results of a series of shorter duration ten-cell stack tests being performed during FY08, funded by NGNP. This series of tests was aimed at evaluating stack performance with different interconnect materials and coatings and with or without brazed edge rails. The best performing stack from the FY08 series, in which five different interconnect/coating/edge rail combinations were tested, will be selected for the FY09 long-term test described herein.

Aim: To assess long-term outcome of silastic joint replacement of the first metatarsophalangeal joint. Methods: Thirty-two patients (42 feet) with double-stem silicone implant arthroplasty of the first metatarsophalangeal joint were reviewed at an average of 8 years (range 419 years). Surgery was for hallux rigidus in 25 cases and for hallux valgus with degenerative osteoarthritis in 17 cases. Patients with rheumatoid arthritis were excluded. Mean patient age was 64 years. Results: Twenty-eight of the 32 patients were very satisfied with the procedure. No patients were dissatisfied. Pain relief was subjectively excellent or good in 28 patients. Three of the four patients with fair or poor relief of pain had surgery for hallux valgus with degenerative osteoarthritis. Radiographs showed sclerosis around all prostheses having cysts with bony erosions in 17 cases. Twelve had clinical features of silicone synovitis in the early postoperative period but this was not present at final review despite radiological findings of new bone formation (57%) and localised osteolysis (40%). Two patients had transfer metatarsalgia with a stress fracture. No patient required revision surgery. Conclusion: Our long-term study shows patients to have very good subjective and objective results despite poor radiological results. There is a role for double-stemmed silicone implant arthroplasty in low demand patients.

Long-term stabilisation of grid connected wind farms with FACTS controllers  

Science Journals Connector (OSTI)

The increasing power demand has led to the growth of new technologies that play an integral role in shaping the future energy market. Keeping in view of the environmental constraints, grid connected wind turbines are promising in increasing system reliability. This paper presents the impact of FACTS controllers on the long-term dynamic stability of power systems connected with wind farms based on doubly fed induction generator systems. The stability assessment is made first for a three-phase short circuit without the FACTS controllers in the power network and then with the FACTS controllers. The long-term dynamic simulation results yield information on: 1) the impact of faults and slow wind speed changes on the performance of wind driven induction generators; 2) the change in controllable parameters of the FACTS controllers following the faults and wind speed changes; 3) transient reactive power ratings of FACTS controllers for enhancement of rotor speed stability of induction generators and angle stability of synchronous generators.

Long Term Stewardship Challenges at the St. Louis District FUSRAP Sites  

SciTech Connect (OSTI)

Non-Federally owned radioactively contaminated sites in St. Louis, Missouri are currently being remediated by the St. Louis District Corps of Engineers under the Formerly Utilized Sites Remedial Action Program (FUSRAP). When FUSRAP remediation is complete, inaccessible soils which have levels of contamination greater than unrestricted use standards, will remain. The purpose of this paper is to document the initial challenges facing the project team during its development of the Long Term Stewardship plan for the management of these soils. These soils are located under buildings, roads, railroads and bridges. The Long Term Stewardship plan for the majority of the sites is being developed simultaneously with the remedy selection process. A living document, it will ultimately document the remedial action end state and location of inaccessible soils and implement the plan for ensuring these soils are not a threat to human health and the environment. Although these soils are protective in their current configuration, at some point in time, when activities such as maintenance, utility or property improvement occur, the soils will become accessible and need to be addressed by the federal government. Up until that point in time they will need to be effectively managed to ensure they remain protective. The St. Louis District is in the process of collaboratively developing this plan with its regulators, affected stakeholders and interested parties.

Gasbuggy, New Mexico Long-Term Hydrologic Monitoring Program Evaluation Report  

SciTech Connect (OSTI)

This report summarizes an evaluation of the Long-Term Hydrologic Monitoring Program (LTHMP) that has been conducted since 1972 at the Gasbuggy, New Mexico underground nuclear detonation site. The nuclear testing was conducted by the U.S. Atomic Energy Commission under the Plowshare program, which is discussed in greater detail in Appendix A. The detonation at Gasbuggy took place in 1967, 4,240 feet below ground surface, and was designed to fracture the host rock of a low-permeability natural gas-bearing formation in an effort to improve gas production. The site has historically been managed under the Nevada Offsites Project. These underground nuclear detonation sites are within the United States but outside of the Nevada Test Site where most of the experimental nuclear detonations conducted by the U.S. Government took place. Gasbuggy is managed by the U.S. Department of Energy (DOE) Office of Legacy Management (LM ).

Long-Term Monitoring of Mini-Split Ductless Heat Pumps in the Northeast  

SciTech Connect (OSTI)

Transformations, Inc. has extensive experience building their high performance housing at a variety of Massachusetts locations, in both a production and custom home setting. The majority of their construction uses mini-split heat pumps (MSHPs) for space conditioning. This research covered the long-term performance of MSHPs in Zone 5A; it is the culmination of up to three years' worth of monitoring in a set of eight houses. This research examined electricity use of MSHPs, distributions of interior temperatures and humidity when using simplified (two-point) heating systems in high performance housing, and the impact of door open/closed status on temperature distributions. The use of simplified space conditioning distribution (MSHPs) provides significant first cost savings, which are used to offset the increased investment in the building enclosure.

Two Cases of Loss of Consciousness After Long-Term Memantine Treatment  

Science Journals Connector (OSTI)

Memantine is approved for treatment of moderate to severe Alzheimer disease (AD) but is also investigated as a treatment option for a number of different conditions, and even though there are reports of a number of adverse effects, including new-onset seizures and psychosis, it is considered to be generally well tolerated. We report two cases of repeated loss of consciousness after long-term memantine treatment in patients with AD, which resolved after its discontinuation. The possible changes in the central nervous system after prolonged memantine use for AD are briefly discussed, as well as its capacity to facilitate and/or change the expression of seizure activities. Presented cases indicate the need for increased caution and careful weighing of benefits and risks of prolonged treatment with memantine in patients with AD, as well as for careful evaluation of risks of combining memantine with other medications.

Biogeochemical Cycling and Environmental Stability of Pu Relevant to Long-Term Stewardship of DOE Sites  

SciTech Connect (OSTI)

The overall objective of this research is to understand the biogeochemical cycling of Pu in environments of interest to long-term DOE stewardship issues. Central to Pu cycling (transport initiation and immobilization) is the role of microorganisms. The hypothesis underlying this work is that microbial activity is the causative agent in initiating the mobilization of Pu in near-surface environments: through the transformation of Pu associated with solid phases, production of extracellular polymeric substances (EPS) carrier phases and the creation of microenvironments. Also, microbial processes are central to the immobilization of Pu species, through the metabolism of organically complexed Pu species and Pu associated with extracellular carrier phases and the creation of environments favorable for Pu transport retardation.

Long-term desorption behavior of uranium and neptunium in heterogeneous volcanic tuff materials /  

SciTech Connect (OSTI)

Uranium and neptunium desorption were studied in long-term laboratory experiments using four well-characterized volcanic tuff cores collected from southeast of Yucca Mountain, Nevada. The objectives of the experiments were to 1. Demonstrate a methodology aimed at characterizing distributions of sorption parameters (attributes of multiple sorption sites) that can be applied to moderately-sorbing species in heterogeneous systems to provide more realistic reactive transport parameters and a more realistic approach to modeling transport in heterogeneous systems. 2. Focus on uranium and neptunium because of their high solubility, relatively weak sorption, and high contributions to predicted dose in Yucca Mountain performance assessments. Also, uranium is a contaminant of concern at many DOE legacy sites and uranium mining sites.

Parametric Analysis of PWR Spent Fuel Depletion Parameters for Long-Term-Disposal Criticality Safety  

SciTech Connect (OSTI)

Utilization of burnup credit in criticality safety analysis for long-term disposal of spent nuclear fuel allows improved design efficiency and reduced cost due to the large mass of fissile material that will be present in the repository. Burnup-credit calculations are based on depletion calculations that provide a conservative estimate of spent fuel contents (in terms of criticality potential), followed by criticality calculations to assess the value of the effective neutron multiplication factor (k(sub)eff) for the a spent fuel cask or a fuel configuration under a variety of probabilistically derived events. In order to ensure that the depletion calculation is conservative, it is necessary to both qualify and quantify assumptions that can be made in depletion models.

In utero and early life arsenic exposure in relation to long-term health and disease  

SciTech Connect (OSTI)

Background: There is a growing body of evidence that prenatal and early childhood exposure to arsenic from drinking water can have serious long-term health implications. Objectives: Our goal was to understand the potential long-term health and disease risks associated with in utero and early life exposure to arsenic, as well as to examine parallels between findings from epidemiological studies with those from experimental animal models. Methods: We examined the current literature and identified relevant studies through PubMed by using combinations of the search terms arsenic, in utero, transplacental, prenatal and fetal. Discussion: Ecological studies have indicated associations between in utero and/or early life exposure to arsenic at high levels and increases in mortality from cancer, cardiovascular disease and respiratory disease. Additional data from epidemiologic studies suggest intermediate effects in early life that are related to risk of these and other outcomes in adulthood. Experimental animal studies largely support studies in humans, with strong evidence of transplacental carcinogenesis, atherosclerosis and respiratory disease, as well as insight into potential underlying mechanisms of arsenic's health effects. Conclusions: As millions worldwide are exposed to arsenic and evidence continues to support a role for in utero arsenic exposure in the development of a range of later life diseases, there is a need for more prospective studies examining arsenic's relation to early indicators of disease and at lower exposure levels. - Highlights: We review in utero and early-life As exposure impacts on lifelong disease risks. Evidence indicates that early-life As increases risks of lung disease, cancer and CVD. Animal work largely parallels human studies and may lead to new research directions. Prospective studies and individual exposure assessments with biomarkers are needed. Assessing intermediary endpoints may aid early intervention and establish causality.

Posterior chamber phakic intraocular lens to correct myopia: Long-term follow-up  

Science Journals Connector (OSTI)

Purpose To evaluate the long-term safety and efficacy of a refractive phakic intraocular lens (pIOL) (PRL) to correct moderate to high myopia. Setting Department of Ophthalmology, University Medicine Charit Berlin, Berlin, Germany. Design Retrospective cohort study. Methods Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, intraocular pressure, endothelial cell loss, and adverse events were evaluated. Results The study enrolled 53 eyes (mean spherical equivalent [SE] ?12.17 diopters [D] 4.12 [SD]) of 29 patients. The mean age was 34.6 9.2 years and the mean follow-up, 86 21.2 months. The mean UDVA improved from 1.37 0.28 logMAR preoperatively to 0.14 0.19 logMAR at the last postoperative visit (P<.05). The mean CDVA improved from 0.10 0.18 logMAR to ?0.01 0.09 logMAR (P<.05). The overall mean efficacy index and mean safety index were 0.9 and 1.21, respectively, at the last follow-up visit. The mean endothelial cell loss at the last follow-up was 6.4%. The complications were slight posterior chamber (PC) pIOL decentration (5 eyes, 9.4%), severe PC pIOL decentration resulting in pIOL removal (1 eye, 1.8%), glaucoma (4 eyes, 7.5%), clinically significant cortical lens opacification resulting in cataract surgery (4 eyes, 7.5%), clinically asymptomatic anterior subcapsular cataract formation (6 eyes, 11.3%), and retinal detachment (2 eyes, 3.8%). Conclusions Posterior chamber phakic pIOL implantation to correct moderate to high myopia provided predictable and stable refractive results but with a high rate of serious complications over the long term.

Long-Term Instrumental and Reconstructed Temperature Records Contradict Anthropogenic Global Warming  

E-Print Network [OSTI]

Monthly instrumental temperature records from 5 stations in the northern hemisphere are analyzed, each of which is local and over 200 years in length, as well as two reconstructed long-range yearly records - from a stalagmite and from tree rings that are about 2000 years long. In the instrumental records, the steepest 100-year temperature fall happened in the 19th century and the steepest rise in the 20th century, both events being of about the same magnitude. Evaluation by the detrended fluctuation analysis (DFA) yields Hurst exponents that are in good agreement with the literature. DFA, Monte Carlo simulations, and synthetic records reveal that both 100-year events were caused by external trends. In contrast to this, the reconstructed records show stronger 100-year rises and falls as quite common during the last 2000 years. These results contradict the hypothesis of an unusual (anthropogenic) global warming during the 20th century. As a hypothesis, the sun's magnetic field, which is correlated with sunspot numbers, is put forward as an explanation. The long-term low-frequency fluctuations in sunspot numbers are not detectable by the DFA in the monthly instrumental records, resulting in the common low Hurst exponents. The same does not hold true for the 2000-year-long reconstructed records, which explains both their higher Hurst exponents and the higher probabilities of strong 100-year temperature fluctuations. A long-term synthetic record that embodies the reconstructed sunspot number fluctuations includes the different Hurst exponents of both the instrumental and the reconstructed records and, therefore, corroborates the conjecture.

Endovenous Laser Treatment of Saphenous Vein Reflux: Long-Term Results  

E-Print Network [OSTI]

PURPOSE: To report long-term follow-up results of endovenous laser treatment for great saphenous vein (GSV) reflux caused by saphenofemoral junction (SFJ) incompetence. MATERIALS AND METHODS: Four hundred ninety-nine GSVs in 423 subjects with varicose veins were treated over a 3-year period with 810-nm diode laser energy delivered percutaneously into the GSV via a 600-m fiber. Tumescent anesthesia (100200 mL of 0.2 % lidocaine) was delivered perivenously under ultrasound (US) guidance. Patients were evaluated clinically and with duplex US at 1 week, 1 month, 3 months, 6 months, 1 year, and yearly thereafter to assess treatment efficacy and adverse reactions. Compression sclerotherapy was performed in nearly all patients at follow-up for treatment of associated tributary varicose veins and secondary telangiectasia. RESULTS: Successful occlusion of the GSV, defined as absence of flow on color Doppler imaging, was noted in 490 of 499 GSVs (98.2%) after initial treatment. One hundred thirteen of 121 limbs (93.4%) followed for 2 years have remained closed, with the treated portions of the GSVs not visible on duplex imaging. Of note, all recurrences have occurred before 9 months, with the majority noted before 3 months. Bruising was noted in 24 % of patients and tightness along the course of the treated vein was present in 90 % of limbs. There have been no skin burns, paresthesias, or cases of deep vein thrombosis. CONCLUSIONS: Long-term results available in 499 limbs treated with endovenous laser demonstrate a recurrence

Three-dimensional general relativistic hydrodynamics II: long-term dynamics of single relativistic stars  

E-Print Network [OSTI]

This is the second in a series of papers on the construction and validation of a three-dimensional code for the solution of the coupled system of the Einstein equations and of the general relativistic hydrodynamic equations, and on the application of this code to problems in general relativistic astrophysics. In particular, we report on the accuracy of our code in the long-term dynamical evolution of relativistic stars and on some new physics results obtained in the process of code testing. The tests involve single non-rotating stars in stable equilibrium, non-rotating stars undergoing radial and quadrupolar oscillations, non-rotating stars on the unstable branch of the equilibrium configurations migrating to the stable branch, non-rotating stars undergoing gravitational collapse to a black hole, and rapidly rotating stars in stable equilibrium and undergoing quasi-radial oscillations. The numerical evolutions have been carried out in full general relativity using different types of polytropic equations of state using either the rest-mass density only, or the rest-mass density and the internal energy as independent variables. New variants of the spacetime evolution and new high resolution shock capturing (HRSC) treatments based on Riemann solvers and slope limiters have been implemented and the results compared with those obtained from previous methods. Finally, we have obtained the first eigenfrequencies of rotating stars in full general relativity and rapid rotation. A long standing problem, such frequencies have not been obtained by other methods. Overall, and to the best of our knowledge, the results presented in this paper represent the most accurate long-term three-dimensional evolutions of relativistic stars available to date.

ANOMALOUS LOW STATES AND LONG-TERM VARIABILITY IN THE BLACK HOLE BINARY LMC X-3  

SciTech Connect (OSTI)

Rossi X-ray Timing Explorer observations of the black hole binary LMC X-3 reveal an extended very low X-ray state lasting from 2003 December 13 until 2004 March 18, unprecedented both in terms of its low luminosity (>15 times fainter than ever before seen in this source) and long duration ({approx}3 times longer than a typical low/hard state excursion). During this event little to no source variability is observed on timescales of {approx}hours-weeks, and the X-ray spectrum implies an upper limit of 1.2 Multiplication-Sign 10{sup 35} erg s{sup -1}. Five years later another extended low state occurs, lasting from 2008 December 11 until 2009 June 17. This event lasts nearly twice as long as the first, and while significant variability is observed, the source remains reliably in the low/hard spectral state for the {approx}188 day duration. These episodes share some characteristics with the 'anomalous low states' in the neutron star binary Her X-1. The average period and amplitude of the variability of LMC X-3 have different values between these episodes. We characterize the long-term variability of LMC X-3 before and after the two events using conventional and nonlinear time series analysis methods, and show that, as is the case in Her X-1, the characteristic amplitude of the variability is related to its characteristic timescale. Furthermore, the relation is in the same direction in both systems. This suggests that a similar mechanism gives rise to the long-term variability, which in the case of Her X-1 is reliably modeled with a tilted, warped precessing accretion disk.

Two long-term instrumental climatic data bases of the People`s Republic of China  

SciTech Connect (OSTI)

Two long-term instrumental data bases containing meteorological observations from the People`s Republic of China (PRC) are described. These data sets were compiled in accordance with a joint research agreement signed by the United States Department of Energy (DOE) and the PRC Chinese Academy of Sciences (CAS) on August 19, 1987. CAS has provided records from 265 stations, partitioned into networks of 60 and 205 stations which each provide good geographical coverage of the PRC. The 60-station network data contain monthly measurements of barometric pressure, air temperature, precipitation amount, relative humidity, sunshine duration, cloud amount, wind direction and speed, and number of days with snow cover. Detailed station histories are presented for all 60 stations. The 205-station network data contain monthly mean temperatures and monthly precipitation totals; however, station histories are not currently available. Sixteen stations from these data sets (13 from the 60-station, 3 from the 205-station) have temperature and/or precipitation records which begin prior to 1900, whereas the remaining stations began observing in the early to mid 1900s. Records from the 262 stations extend through 1988; the remaining three station records extend through the early 1980s. These data can be used in defining regional climate changes, establishing relationships between regional and large-scale climates, and in studying the climatic impacts of urbanization and increased concentrations of greenhouse gases. Additional uses could include examining impacts of periodic events such as volcanic eruptions or the El Nino/Southern Oscillation (ENSO). These data sets represent the most comprehensive, long-term instrumental Chinese climate data presently available.

Deriving long term snow cover extent dataset from AVHRR and MODIS data: Central Asia case study  

Science Journals Connector (OSTI)

Abstract We computed the daily AVHRR snow cover from all available AVHRR level1b raw data over central Asia (CA) with an aggregated rating based snow identification scheme. The daily AVHRR snow cover was further processed into an 8-day maximum-snow-extent data, and then went through a set of spatial and temporal filters to fill cloud or gap pixels. A correction method based on known long term snow probability in small sub-regions has been developed for computing corrected 8-day AVHRR snow cover, which is comparable to 8-day MODIS snow data. Validation of the daily AVHRR snow product against ground snow survey suggested a high accuracy of the snow identification scheme. Comparison of the daily AVHRR snow cover with the daily MODIS snow cover in Amu Dar'ya River basin within CA showed high accuracy of daily AVHRR snow, with a general accuracy of 99.60% and Kappa Coefficient of 0.92 in the basin. Comparison of the corrected 8-day AVHRR snow cover with 8-day MODIS cloud/gap free snow cover in the same basin also showed high comparability between both data, with a general accuracy of 95.61% and Kappa Coefficient of 0.84. Seasonal snow cover analysis in Amu Dar'ya River basin revealed the spatial and temporal patterns of snow distribution and negative trends in snow cover duration in 1986 to 2008 due to earlier snow melting dates. The newly developed long-term snow dataset from AVHRR and MODIS data over CA, with its high accuracy and internal comparability, is suitable for seasonal snow cover studies in mountainous regions over CA.

Long-term passive CANDU containment response after a design-basis accident  

SciTech Connect (OSTI)

A {open_quotes}passive{close_quotes} CANDU{reg_sign} containment system, currently being developed, is aimed at limiting the consequences of a postulated accident, by ensuring the structural integrity of the containment building and limiting fission-product release to within siting dose limits, without operator action or reliance on ac power for up to 3 d. All main functions of the containment system, i.e. energy removal, hydrogen mitigation, and fission-product retention, are to be accomplished passively. The passive CANDU containment relies on the passive emergency water system (PEWS) for energy removal after an accident and on passive autocatalytic recombiners (PAR) for hydrogen removal. The key feature of this concept, is a recirculating, buoyancy-driven flow through the recombiners and the tube banks of the PEWS. This paper presents preliminary design calculations for the PEWS tank and tube banks and a simulation of the long-term passive containment response, based on the current CANDU-6 containment, to a large loss-of-coolant/loss-of- emergency coolant injection (LOCA/LOECI) using the GOTHIC code. It is shown that a 1500-M{sup 3} PEWS tank, connected to tube banks with a total surface area of 1800 m{sup 2}, can limit the second pressure peak to about 300 kPa(a) if a recirculating flow is established in the containment building. The PEWS tank water is boiling in the long term, and the peak containment temperature is 114{degrees}C. 6 refs., 4 figs.

Differentiated long term projections of the hourly electricity consumption in local areas. The case of Denmark West  

Science Journals Connector (OSTI)

Abstract Assessing grid developments the spatial distribution of the electricity consumption is important. In Denmark the electricity grid consists of transmission and local distribution grids with different voltages that are connected via transformer stations each covering a local area with between 10.000 and 100.000 customers. Data for the hourly electricity consumption at transformer stations shows that the profile of consumption differs considerably between local areas, and this is partly due to a different weight of categories of customers in the different areas. Categories of customers have quite distinct consumption profiles and contribute quite differently to the aggregated load profile. In forecasts, demand by categories of customers is expected to develop differently implying that both the level and the profile of consumption at each transformer stations are expected to change differently. Still, in the previous planning of the transmission grid in Denmark specific local conditions have not been considered. As a first step towards differentiated local load forecasts, the paper presents a new model for long term projections of consumption in local areas and illustrates a first use of the model related to the transmission grid planning by the Danish TSO Energinet.dk. The model is a distribution system that distributes hourly consumption in an aggregated area to hourly consumption at each transformer station. Using econometrics, the model is estimated on national statistics for the hourly consumption by categories of customers and data for the hourly consumption at each transformer station for the years 20092011. Applying the model for load forecasts, a major conclusion is that different transformer stations will experience different changes both in the level - and in the hourly profile of load.

Coal investment and long-term supply and demand outlook for coal in the Asia-Pacific Region  

SciTech Connect (OSTI)

The theme of this symposium to look ahead almost a quarter century to 2020 gives one the freedom to speculate more than usual in projections for coal. It is important to attempt to take a long term look into the future of coal and energy, so that one can begin to prepare for major changes on the horizon. However, it would be a mistake to believe that the crystal ball for making long term projections is accurate for 2020. Hopefully it can suggest plausible changes that have long term strategic importance to Asia`s coal sector. This paper presents the medium scenario of long term projects of coal production, consumption, imports and exports in Asia. The second part of the paper examines the two major changes in Asia that could be most important to the long term role of coal. These include: (1) the impact of strict environmental legislation on energy and technology choices in Asia, and (2) the increased role of the private sector in all aspects of coal in Asia.

Novel effects of demand side management data on accuracy of electrical energy consumption modeling and long-term forecasting  

Science Journals Connector (OSTI)

Abstract Worldwide implementation of demand side management (DSM) programs has had positive impacts on electrical energy consumption (EEC) and the examination of their effects on long-term forecasting is warranted. The objective of this study is to investigate the effects of historical DSM data on accuracy of EEC modeling and long-term forecasting. To achieve the objective, optimal artificial neural network (ANN) models based on improved particle swarm optimization (IPSO) and shuffled frog-leaping (SFL) algorithms are developed for EEC forecasting. For long-term EEC modeling and forecasting for the U.S. for 20102030, two historical data types used in conjunction with developed models include (i) EEC and (ii) socio-economic indicators, namely, gross domestic product, energy imports, energy exports, and population for 19672009 period. Simulation results from IPSO-ANN and SFL-ANN models show that using socio-economic indicators as input data achieves lower mean absolute percentage error (MAPE) for long-term EEC forecasting, as compared with EEC data. Based on IPSO-ANN, it is found that, for the U.S. EEC long-term forecasting, the addition of DSM data to socio-economic indicators data reduces MAPE by 36% and results in the estimated difference of 3592.8 MBOE (5849.9TWh) in EEC for 20102030.

On the consumption insurance effects of long-term care insurance in Japan: Evidence from micro-level household data  

Science Journals Connector (OSTI)

Using micro-level household data in the 2001 Comprehensive Survey of the Living Conditions of the People on Health and Welfare compiled by the Japanese Ministry of Health, Labor and Welfare, this paper examines how having a household member in need of long-term nursing care can result in welfare losses measured in terms of consumption. In so doing, this study evaluates the role of the public long-term care insurance scheme implemented in Japan in April 2000. The results indicate that when households include a disabled family member, household consumption net of long-term care costs do not decrease as much as before the introduction of long-term care insurance. Further, when compared with the surveys conducted in 1998, the adverse effects on consumption net of long-term care costs have become much weaker. These findings suggest that the introduction of social insurance in 2000 helped Japanese households to reduce the welfare losses associated with a disabled family member.

Long-Term Surveillance and Maintenance at Rocky Flats: Early Experiences and Lessons Learned  

SciTech Connect (OSTI)

The U.S. Department of Energy's (DOE's) Rocky Flats Site was established in 1951 as part of the United States' nationwide nuclear weapons complex to manufacture nuclear weapons components. In 1992 weapons production halted, and the Rocky Flats mission changed to include environmental investigations, cleanup, and site closure. In October 2005, DOE and its contractor completed an accelerated 10-year, $7 billion cleanup of chemical and radiological contamination left from nearly 50 years of production. The cleanup required the decommissioning, decontamination, demolition, and removal of more than 800 structures; removal of more than 500,000 cubic meters of low-level radioactive waste; and remediation of more than 360 potentially contaminated environmental sites. The final remedy for the site was selected in September 2006 and included institutional controls, physical controls, and continued monitoring for the former industrial portion of the site. The remainder of the site, which served as a buffer zone surrounding the former industrial area, was transferred to the U.S. Fish and Wildlife Service in July 2007 for a national wildlife refuge. DOE's Office of Legacy Management is responsible for the long-term surveillance and maintenance of Rocky Flats, which includes remedy implementation activities and general site maintenance. Several factors have complicated the transition from closure to post-closure at Rocky Flats. The early experiences associated with the two years since the physical cleanup and closure work were completed have led to several valuable lessons learned. (authors)

The U.S. regulatory framework for long-term management of uranium mill tailings  

SciTech Connect (OSTI)

The US established the regulatory structure for the management, disposal, and long-term care of uranium mill tailings in 1978 with the passage of the Uranium Mill Tailings Radiation Control Act (UMTRCA) (Pub. L. 95-604). This legislation has governed the cleanup and disposal of uranium tailings at both inactive and active sites. The passage of the UMTRCA established a federal regulatory program for the cleanup and disposal of uranium mill tailings in the US. This program involves the DOE, the NRC, the EPA, various states and tribal governments, private licensees, and the general public. The DOE has completed surface remediation at 14 sites, with the remaining sites either under construction or in planning. The DOE`s UMTRA Project has been very successful in dealing with public and agency demands, particularly regarding disposal site selection and transportation issues. The active sites are also being cleaned up, but at a slower pace than the inactive sites, with the first site tentatively scheduled for completion in 1996.

Long-term effects of prenatal x-ray of human females: mortality and morbidity  

SciTech Connect (OSTI)

Experimental studies and long-term studies of humans exposed to ionizing radiation in utero and after birth show that these exposures increase the risk of cancer in childhood and in later life. A possible life-shortening effect has also been reported. This study followed to their mid-twenties 1458 women exposed in utero to diagnostic x-rays and 1458 matched, unexposed controls in Baltimore, Maryland, and obtained responses from over 100 women in each group. Information about general health and specific diseases was obtained from questionnaires. Deaths were ascertained through family members and death certificates. Mortality rates were slightly higher among exposure. Exposed women reported poor general health significantly more often than controls. Specific diseases occurred similarly in the two groups, although exposed women reported more epilepsy or fits, more ovarian tumors, and more high blood pressure. These strong correlation between weight and high blood pressure and the heavier weights of exposed women seemed to account for this difference. In summary, these matched exposed and control women, followed to their mid-twenties, experienced similar rates of morbidity and mortality. Radiation-induced cancers and life-shortening effects, if any, might not become evident until older ages.

Heat extracted from the long term flow test in the Fenton Hill HDR reservoir  

SciTech Connect (OSTI)

A long-term flow test was carried out in the Fenton Hill HDR Phase-2 reservoir for 14 months during 1992-1993 to examine the potential for supplying thermal energy at a sustained rate as a commercial demonstration of HDR technology. The test was accomplished in several segments with changes in mean flowrate due to pumping conditions. Re-test estimates of the extractable heat content above a minimum useful temperature were based on physical evidence of the size of the Fenton Hill reservoir. A numerical model was used to estimate the extent of heat extracted during the individual flow segments from the database of measured production data during the test. For a reservoir volume of 6.5x10{sup 6}m{sup 3}, the total heat content above a minimum temperature of 150{degree} C was 1.5x10{sup 15}J. For the total test period at the three sustained mean flowrates, the integrated heat extracted was 0.088x10{sup 15}J, with no discernable temperature decline of the produced fluid. The fraction of energy extracted above the abandonment temperature was 5.9%. On the basis of a constant thermal energy extraction rate, the lifetime of the reservoir (without reservoir growth) to the abandonment temperature would be 13.3 years, in good agreement with the pre-test estimate of 15.0 years for the given reservoir volume.

Long-term sealing analyses for US Strategic Petroleum Reserve (SPR) caverns  

SciTech Connect (OSTI)

It is inevitable that sealing and abandonment will someday occur in a SPR cavern or caverns. To gain insight into the long-term behavior of a typical SPR cavern following sealing and abandonment, a suite of mechanical finite-element calculations was performed. The initial analyses predict how quickly and to what extent a cavern pressurizes after it is plugged. The analyses also examine the stability of the cavern as it changes shape due to the excessive pressures generated as the salt creeps and the brine in the cavern thermally expands. These large-scale analyses do not include the details of the plug but assume a good seal is established in the cavern wells. In another series of analyses, the potential for forming a leak at the plug is evaluated. A cement plug, emplaced in the casing seat of a cavern well, is loaded using the predicted brine pressures from the cavern analyses. The plugged casing analyses examine the potential for forming a leak path in and along the interfaces of salt, casing, and cement plug. In the last set of analysis, the dimensional scale of the problem is further reduced to examine a preexisting crack along a casing/salt interface. The cracked interface is assumed to be fluid filled and fully pressurized by the cavern fluids. The analyses address the potential for the fluid path to extend upwards along a plugged casing should an open microannulus surround the casing after it is plugged.

The significant role of energy calculations in the success of long-term energy guarantees  

SciTech Connect (OSTI)

Situations can arise in long-term energy-savings guarantees in which changes, beyond those caused by the energy conservation measures, will happen to the building or its usage and affect building energy usage and demand. These changes typically occur after the time period that is used to establish a historical usage baseline for the guarantee. When this occurs, a calculated baseline adjustment can provide an effective method of accommodating the change while still retaining the basic tenants of the original energy guarantee. To fill their intended function, baseline adjustments must be accepted as being fair and equitable by both the owner and the performance contractor who is providing the energy guarantee. This is best achieved through energy calculations that logically and objectively apply the physical laws of HVAC to the specific characteristics of the situation. This paper presents examples of the types of situations encountered in four years of extensive performance contracting experience and the calculation approaches that are proving to be the most successful.

Long-Term Surveillance and Maintenance Records: Maintaining Access to the Knowledge - 13122  

SciTech Connect (OSTI)

The U.S. Department of Energy (DOE) Office of Legacy Management (LM) is an integral part of DOE's strategy to ensure that legacy liabilities of former nuclear weapons production sites are properly managed following the completion of environmental cleanup activities. In the area of environmental legacy management, records management is crucial to the protection of health, environmental, and legal interests of the Department and the public. LM is responsible for maintaining long-term surveillance and maintenance (LTS and M) records in performance of its mission. Maintaining access to the knowledge contained in these record collections is one of LM's primary responsibilities. To fulfill this responsibility, LM established a consolidated records management facility, the LM Business Center (LMBC), to house physical media records and electronic records. A new electronic record keeping system (ERKS) was needed to replace an obsolete system while helping to ensure LM is able to meet ongoing responsibilities to maintain access to knowledge and control the life cycle management of records.

Strategic Program Planning Lessons Learned In Developing The Long-Term Stewardship Science and Technology Roadmap  

SciTech Connect (OSTI)

Technology roadmapping is a strategic planning method used by companies to identify and plan the development of technologies necessary for new products. The U.S. Department of Energy's Office of Environmental Management has used this same method to refine requirements and identify knowledge and tools needed for completion of defined missions. This paper describes the process of applying roadmapping to clarify mission requirements and identify enhancing technologies for the Long-Term Stewardship (LTS) of polluted sites after site cleanup has been completed. The nature of some contamination problems is such that full cleanup is not achievable with current technologies and some residual hazards remain. LTS maintains engineered contaminant barriers and land use restriction controls, and monitors residual contaminants until they no longer pose a risk to the public or the environment. Roadmapping was used to clarify the breadth of the LTS mission, to identify capability enhancements needed to improve mission effectiveness and efficiency, and to chart out the research and development efforts to provide those enhancements. This paper is a case study of the application of roadmapping for program planning and technical risk management. Differences between the planned and actual application of the roadmapping process are presented along with lessons learned. Both the process used and lessons learned should be of interest for anyone contemplating a similar technology based planning effort.

Long term black hole evolution with the BSSN system by pseudospectral methods  

SciTech Connect (OSTI)

We present long term evolutions of a single black hole of mass M with the Baumgarte-Shapiro-Shibata-Nakamura (BSSN) system using pseudospectral methods. For our simulations we use the SGRID code where the BSSN system is implemented in its standard second order in space form. Previously we found that such simulations are quite unstable. The main goal of this paper is to present two improvements which now allow us to evolve for longer times. The first improvement is related to the boundary conditions at the excised black hole interior. We now use a gauge condition that ensures that all modes are going into the black hole, so that no boundary conditions are needed at the excision surface. The second more significant improvement has to do with our particular numerical method and involves filters based on projecting the double Fourier expansions used for the angular dependence onto spherical harmonics. With these two improvements it is now easily possible to evolve for several thousand M. The only remaining limitation seems to be the radiative outer boundary conditions used here. Yet this problem can be ameliorated by pushing out the location of the outer boundary, which leads to even longer run times.

SAGE II long-term measurements of stratospheric and upper tropospheric aerosols  

SciTech Connect (OSTI)

The Stratospheric Aerosol and Gas Experiment (SAGE) II solar occultation instrument has been making measurements on stratospheric aerosols and gases continually since October 1984. Observations from the SAGE II instrument provide a valuable long-term data set for study of the aerosol in the stratosphere and aerosol and cloud in the upper troposphere. The period of observation covers the decay phase of material injected by the El Chichon volcanic eruption in 1982, the years 1988--1990 when stratospheric aerosol levels approached background levels, and the period after the eruption of Mount Pinatubo in 1991. The Mount Pinatubo eruption caused the largest perturbation in stratospheric aerosol loading in this century, with effects on stratospheric dynamics and chemistry. The SAGE II data sequence shows the global dispersion of aerosols following the Mount Pinatubo eruption, as well as the changes occurring in stratospheric aerosol mass and surface area. The downward transfer of stratospheric aerosols into the upper troposphere following the earlier eruption of El Chichon is clearly visible. Estimates have been made of the amount of volcanic material lying in the upper troposphere and the way in which this varies with latitude and season.

Data Archive of the Harvard Forest, a Long Term Ecological Research (LTER) Site  

DOE Data Explorer [Office of Scientific and Technical Information (OSTI)]

Since 1907 research and education have been the mission of the Harvard Forest is one of the oldest and most intensively studied forests in North America. Located in Petersham, Massachusetts, its 3000 acres of land have been a center of research and education since 1907. The Long Term Ecological Research (LTER) program, established in 1988 and funded by the National Science Foundation, provides a framework for much of this activity. An understanding of forest responses to natural and human disturbance and environmental change over broad spatial and temporal scales pulls together research topics including biodiversity studies, the effects of invasive organisms, large experiments and permanent plot studies, historical and retrospective studies, soil nutrient dynamics, and plant population and community ecological interactions. Major research in forest-atmosphere exchange, hydrology, and regional studies places the work in regional and global context, aided by modeling tools. Conservation and management research and linkages to policy have been part of the Forest since its beginning, and the approaches used in New England can often apply to international studies.

Uncertainties in Air Exchange using Continuous-Injection, Long-Term Sampling Tracer-Gas Methods  

SciTech Connect (OSTI)

The PerFluorocarbon Tracer (PFT) method is a low-cost approach commonly used for measuring air exchange in buildings using tracer gases. It is a specific application of the more general Continuous-Injection, Long-Term Sampling (CILTS) method. The technique is widely used but there has been little work on understanding the uncertainties (both precision and bias) associated with its use, particularly given that it is typically deployed by untrained or lightly trained people to minimize experimental costs. In this article we will conduct a first-principles error analysis to estimate the uncertainties and then compare that analysis to CILTS measurements that were over-sampled, through the use of multiple tracers and emitter and sampler distribution patterns, in three houses. We find that the CILTS method can have an overall uncertainty of 10-15percent in ideal circumstances, but that even in highly controlled field experiments done by trained experimenters expected uncertainties are about 20percent. In addition, there are many field conditions (such as open windows) where CILTS is not likely to provide any quantitative data. Even avoiding the worst situations of assumption violations CILTS should be considered as having a something like a ?factor of two? uncertainty for the broad field trials that it is typically used in. We provide guidance on how to deploy CILTS and design the experiment to minimize uncertainties.

China's Building Energy Use: A Long-Term Perspective based on a Detailed Assessment  

SciTech Connect (OSTI)

We present here a detailed, service-based model of China's building energy use, nested in the GCAM (Global Change Assessment Model) integrated assessment framework. Using the model, we explore long-term pathways of China's building energy use and identify opportunities of reducing greenhouse gas emissions. The inclusion of a structural model of building energy demands within an integrated assessment framework represents a major methodological advance. It allows for a structural understanding of the drivers of building energy consumption while simultaneously considering the other human and natural system interactions that influence changes in the global energy system and climate. We also explore a range of different scenarios to gain insights into how China's building sector might evolve and what the implications might be for improved building energy technology and carbon policies. The analysis suggests that China's building energy growth will not wane anytime soon, although technology improvement will put downward pressure on this growth. Also, regardless of the scenarios represented, the growth will involve the continued, rapid electrification of the buildings sector throughout the century, and this transition will be accelerated by the implementation of carbon policy.

Use of non evaporable getter pumps to ensure long term performances of high quantum efficiency photocathodes  

SciTech Connect (OSTI)

High quantum efficiency photocathodes are routinely used as laser triggered emitters in the advanced high brightness electron sources based on radio frequency guns. The sensitivity of semiconductor type photocathodes to vacuum levels and gas composition requires special care during preparation and handling. This paper will discuss the results obtained using a novel pumping approach based on coupling a 20?l s{sup ?1} sputter ion getter pump with a CapaciTorr D100 non evaporable getter (NEG) pump. A pressure of 8?10{sup ?8}?Pa was achieved using only a sputter ion pump after a 6?day bake-out. With the addition of a NEG pump, a pressure of 2?10{sup ?9}?Pa was achieved after a 2?day bake-out. These pressure values were maintained without power due to the ability of the NEG to pump gases by chemical reaction. Long term monitoring of cathodes quantum efficiencies was also carried out at different photon wavelengths for more than two years, showing no degradation of the photoemissive film properties.

Long-term changes in the extractability and bioavailability of zinc and cadmium after sludge application  

SciTech Connect (OSTI)

Changes in the extractability and uptake by crops of sludge metals in a long-term field experiment, started in 1942, were measured to assess whether Zn and Cd are either fixed by the sludge/soil constituents or are released as the sludge organic matter (OM) decomposes. Total and 0.1 M CaCl{sub 2}-extractable concentrations of Zn and Cd in soil and total concentrations in crops were measured on archived crop and soil samples. Extractability of Zn as a proportion of the total ranged from 0.5 to 3% and that of Cd from 4 to 18%, and were higher in sludge-amended than farmyard manure or fertilizer-amended soils. Over a 23-yr period after 1961, when sludge was last applied, the extractability of both metals fluctuated, but neither decreased nor increased consistently. The relationships between total soil and crop metal concentrations were linear, with no evidence of a plateau across the range of soil metal concentrations achieved. The slopes of the soil-plant relationships depended on the type of crop or crop part examined, but were generally in the order red beet (Beta vulgaris L.) > sugar beet (Beta vulgaris L.) > carrot (Daucus carota L.) > barley (Hordeum vulgare L.). However, there also were large seasonal differences in metal concentrations in the crops. It is concluded from the available evidence that up to 23 yr after sludge applications cease, Zn and Cd extractability and bioavailability do not decrease.

Ion implantation effects in insulators and the long-term stability of radioactive waste storage materials  

Science Journals Connector (OSTI)

Most insulator materials so far proposed for storing high-level radioactive wastes, such as glass and and the constituent minerals of ceramics are nuclear track detectors. Lead ion implantation experiments show that such materials should be transformed into giant nuclear tracks, when the internal fluence of heavy recoils emitted during the ?-decay of actinide elements stored in them exceeds a critical value, which corresponds to an equivalent storage period of a few thousand years for the wastes expected from a pressurized water reactor. In contrast, actinide bearing minerals are much more stable against ?-recoil damage. As nuclear tracks are extremely chemical reactive, ?-recoil damage is expected to shorten the lifetime of storage materials such as glass and ceramics against dissolution in ground waters. Fortunately new nuclear track concepts are already yielding guidelines for predicting and improving the long-term stability of storage materials. The results of the present studies also bear on the physics of ion implantation phenomena an insulator targets exposed to high fluences of low energy ions.

Long-term electricity demand forecasting for power system planning using economic, demographic and climatic variables  

Science Journals Connector (OSTI)

The stochastic planning of power production overcomes the drawback of deterministic models by accounting for uncertainties in the parameters. Such planning accounts for demand uncertainties by using scenario sets and probability distributions. However, in previous literature, different scenarios were developed by either assigning arbitrary values or assuming certain percentages above or below a deterministic demand. Using forecasting techniques, reliable demand data can be obtained and inputted to the scenario set. This article focuses on the long-term forecasting of electricity demand using autoregressive, simple linear and multiple linear regression models. The resulting models using different forecasting techniques are compared through a number of statistical measures and the most accurate model was selected. Using Ontario's electricity demand as a case study, the annual energy, peak load and base load demand were forecasted up to the year 2025. In order to generate different scenarios, different ranges in the economic, demographic and climatic variables were used.

Long-term criticality control in radioactive waste disposal facilities using depleted uranium  

SciTech Connect (OSTI)

Plant photosynthesis has created a unique planetary-wide geochemistry - an oxidizing atmosphere with oxidizing surface waters on a planetary body with chemically reducing conditions near or at some distance below the surface. Uranium is four orders of magnitude more soluble under chemically oxidizing conditions than it is under chemically reducing conditions. Thus, uranium tends to leach from surface rock and disposal sites, move with groundwater, and concentrate where chemically reducing conditions appear. Earth`s geochemistry concentrates uranium and can separate uranium from all other elements except oxygen, hydrogen (in water), and silicon (silicates, etc). Fissile isotopes include {sup 235}U, {sup 233}U, and many higher actinides that eventually decay to one of these two uranium isotopes. The potential for nuclear criticality exists if the precipitated uranium from disposal sites has a significant fissile enrichment, mass, and volume. The earth`s geochemistry suggests that isotopic dilution of fissile materials in waste with {sup 238}U is a preferred strategy to prevent long-term nuclear criticality in and beyond the boundaries of waste disposal facilities because the {sup 238}U does not separate from the fissile uranium isotopes. Geological, laboratory, and theoretical data indicate that the potential for nuclear criticality can be minimized by diluting fissile materials with-{sup 238}U to 1 wt % {sup 235}U equivalent.

Chaotic mean wind in turbulent thermal convection and long-term correlations in solar activity  

E-Print Network [OSTI]

It is shown that correlation function of the mean wind velocity in a turbulent thermal convection (Rayleigh number $Ra \\sim 10^{11}$) exhibits exponential decay with a very long correlation time, while corresponding largest Lyapunov exponent is certainly positive. These results together with the reconstructed phase portrait indicate presence of a chaotic component in the examined mean wind. Telegraph approximation is also used to study relative contribution of the chaotic and stochastic components to the mean wind fluctuations and an equilibrium between these components has been studied. Since solar activity is based on the thermal convection processes, it is reasoned that the observed solar activity long-term correlations can be an imprint of the mean wind chaotic properties. In particular, correlation function of the daily sunspots number exhibits exponential decay with a very long correlation time and corresponding largest Lyapunov exponent is certainly positive, also relative contribution of the chaotic and stochastic components follows the same pattern as for the convection mean wind.

Long-term in vivo regeneration of peripheral nerves through bioengineered nerve grafts  

Science Journals Connector (OSTI)

Although autologous nerve graft is still the first choice strategy in nerve reconstruction, it has the severe disadvantage of the sacrifice of a functional nerve. Cell transplantation in a bioartificial conduit is an alternative strategy to improve nerve regeneration. Nerve fibrin conduits were seeded with various cell types: primary Schwann cells (SC), SC-like differentiated bone marrow-derived mesenchymal stem cells (dMSC), SC-like differentiated adipose-derived stem cells (dASC). Two further control groups were fibrin conduits without cells and autografts. Conduits were used to bridge a 1 cm rat sciatic nerve gap in a long term experiment (16 weeks). Functional and morphological properties of regenerated nerves were investigated. A reduction in muscle atrophy was observed in the autograft and in all cell-seeded groups, when compared with the empty fibrin conduits. SC showed significant improvement in axon myelination and average fiber diameter of the regenerated nerves. dASC were the most effective cell population in terms of improvement of axonal and fiber diameter, evoked potentials at the level of the gastrocnemius muscle and regeneration of motoneurons, similar to the autografts. Given these results and other advantages of adipose derived stem cells such as ease of harvest and relative abundance, dASC could be a clinically translatable route towards new methods to enhance peripheral nerve repair.

Current Understanding and Remaining Challenges in Modeling Long-Term Degradation of Borosilicate Nuclear Waste Glasses  

SciTech Connect (OSTI)

Chemical durability is not a single material property that can be uniquely measured. Instead it is the response to a host of coupled material and environmental processes whose rates are estimated by a combination of theory, experiment, and modeling. High-level nuclear waste (HLW) glass is perhaps the most studied of any material yet there remain significant technical gaps regarding their chemical durability. The phenomena affecting the long-term performance of HLW glasses in their disposal environment include surface reactions, transport properties to and from the reacting glass surface, and ion exchange between the solid glass and the surrounding solution and alteration products. The rates of these processes are strongly influenced and are coupled through the solution chemistry, which is in turn influenced by the reacting glass and also by reaction with the near-field materials and precipitation of alteration products. Therefore, those processes must be understood sufficiently well to estimate or bound the performance of HLW glass in its disposal environment over geologic time-scales. This article summarizes the current state of understanding of surface reactions, transport properties, and ion exchange along with the near-field materials and alteration products influences on solution chemistry and glass reaction rates. Also summarized are the remaining technical gaps along with recommended approaches to fill those technical gaps.

Hanford Site Long-term Surface Barrier Development Program: Fiscal year 1994 highlights  

SciTech Connect (OSTI)

The Hanford Site Surface Barrier Development Program was organized in 1985 to test the effectiveness of various barrier designs in minimizing the effects of water infiltration; plant, animal and human intrusion; and wind and water erosion on buried wastes, plus preventing or minimizing the emanation of noxious gases. A team of scientists from the Pacific Northwest Laboratory (PNL) and engineers from Westinghouse Hanford Company (WHC) direct the barrier development effort. ICF Kaiser Hanford Company, in conjunction with WHC and PNL, developed design drawings and construction specifications for a 5-acre prototype barrier. The highlight of efforts in FY 1994 was the construction of the prototype barrier. The prototype barrier was constructed on the Hanford Site at the 200 BP-1 Operable Unit of the 200 East Area. Construction was completed in August 1994 and monitoring instruments are being installed so experiments on the prototype barrier can begin in FY 1995. The purpose of the prototype barrier is to provide insights and experience with issues regarding barrier design, construction, and performance that have not been possible with individual tests and experiments conducted to date. Additional knowledge and experience was gained in FY 1994 on erosion control, physical stability, water infiltration control, model testing, Resource Conservation and Recovery Act (RCRA) comparisons, biointrusion control, long-term performance, and technology transfer.

Long-term surveillance plan for the Falls City Disposal Site, Falls City, Texas. Revision 2  

SciTech Connect (OSTI)

The need for ground water monitoring at the Falls City disposal site was evaluated in accordance with NRC regulations and guidelines established by the DOE in Guidance for Implementing the Long-term Surveillance Program for UMTRA Project Title 1 Disposal Sites (DOE, 1996). Based on evaluation of site characterization data, it has been determined that a program to monitor ground water for demonstration of disposal cell performance based on a set of concentration limits is not appropriate because ground water in the uppermost aquifer is of limited use, and a narrative supplemental standard has been applied to the site that does not include numerical concentration limits or a point of compliance. The limited use designation is based on the fact that ground water in the uppermost aquifer is not currently or potentially a source of drinking water in the area because it contains widespread ambient contamination that cannot be cleaned up using methods reasonably employed by public water supply systems. Background ground water quality varies by orders of magnitude since the aquifer is in an area of redistribution of uranium mineralization derived from ore bodies. The DOE plans to perform post-closure ground water monitoring in the uppermost aquifer as a best management practice (BMP) as requested by the state of Texas.

The challenges measuring the effectiveness of a statewide Medicaid long-term care managed care programme: the Florida experience  

Science Journals Connector (OSTI)

Recent passage of legislation in Florida mandating the development of a statewide Medicaid managed care long-term care plan was initiated to facilitate the utilisation of home- and community-based long-term care services in place of high cost, non-skilled nursing home care. However, programme savings will be limited if the care needs of nursing home residents exceed that currently provided by community-based programmes. This article reports on the challenges that arose from our efforts to compare the care burden of nursing home residents and nursing home-eligible Medicaid waiver programme enrolees. Our experience will better enable policy researchers and managed care plans to design comparative effective studies that address the rebalancing of long-term care resources.

Long-term trends in temperature of the Arctic atmosphere and their relation to variations of solar activity  

Science Journals Connector (OSTI)

The solar activity expressed in its various forms (the total solar irradiance (TSI) and a permanent injection of the solar charged particles called as the solar wind) is considered in this study as a possible candidate capable to influence on the long-term variations of the atmospheric temperature. The data of atmospheric balloon sounding at four polar and subpolar stations were chosen for the study of long-term variations of atmospheric temperature as functions of the solar activity. The experimentally observed long-term trends in variations of the tropospheric and stratospheric temperatures could be related to some extent to the variability of the solar activity. The impact of the solar wind energy on thermal regime of the stratosphere and troposphere in the Arctic could be different due to non-uniformity of electric conductivity of the ground surface as well as to different relations between conductivity of the atmospheric layers and ground surface.

7 - Assessing and modelling the performance of nuclear waste and associated packages for long-term management  

Science Journals Connector (OSTI)

Abstract: Examples of analytical approaches and methodologies for modelling the behaviour of waste forms and waste package metals in long-term management of spent nuclear fuel (SNF) and high level waste (HLW) are presented. Two cases, long-term geological disposal and interim extended dry storage, are considered. The integrity of the waste package (or canister) that serves as a barrier is dependent upon the performance of construction metals. Corrosion degradation modes of the construction metals are evaluated. The waste behaviour during SNF degradation is also evaluated. In each mode of corrosion or degradation, the associated risk insights are discussed in the system performance of disposal or storage.

Long-Term Instrumentation, Information, and Control Systems (II&C) Modernization Future Vision and Strategy  

SciTech Connect (OSTI)

Life extension beyond 60 years for the U.S operating nuclear fleet requires that instrumentation and control (I&C) systems be upgraded to address aging and reliability concerns. It is impractical for the legacy systems based on 1970's vintage technology operate over this extended time period. Indeed, utilities have successfully engaged in such replacements when dictated by these operational concerns. However, the replacements have been approached in a like-for-like manner, meaning that they do not take advantage of the inherent capabilities of digital technology to improve business functions. And so, the improvement in I&C system performance has not translated to bottom-line performance improvement for the fleet. Therefore, wide-scale modernization of the legacy I&C systems could prove to be cost-prohibitive unless the technology is implemented in a manner to enable significant business innovation as a means of off-setting the cost of upgrades. A Future Vision of a transformed nuclear plant operating model based on an integrated digital environment has been developed as part of the Advanced Instrumentation, Information, and Control (II&C) research pathway, under the Light Water Reactor (LWR) Sustainability Program. This is a research and development program sponsored by the U.S. Department of Energy (DOE), performed in close collaboration with the nuclear utility industry, to provide the technical foundations for licensing and managing the long-term, safe and economical operation of current nuclear power plants. DOE's program focus is on longer-term and higher-risk/reward research that contributes to the national policy objectives of energy security and environmental security . The Advanced II&C research pathway is being conducted by the Idaho National Laboratory (INL). The Future Vision is based on a digital architecture that encompasses all aspects of plant operations and support, integrating plant systems, plant work processes, and plant workers in a seamless digital environment to enhance nuclear safety, increase productivity, and improve overall plant performance. The long-term goal is to transform the operating model of the nuclear power plants (NPP)s from one that is highly reliant on a large staff performing mostly manual activities to an operating model based on highly integrated technology with a smaller staff. This digital transformation is critical to addressing an array of issues facing the plants, including aging of legacy analog systems, potential shortage of technical workers, ever-increasing expectations for nuclear safety improvement, and relentless pressure to reduce cost. The Future Vision is based on research is being conducted in the following major areas of plant function: (1) Highly integrated control rooms; (2) Highly automated plant; (3) Integrated operations; (4) Human performance improvement for field workers; and (5) Outage safety and efficiency. Pilot projects will be conducted in each of these areas as the means for industry to collectively integrate these new technologies into nuclear plant work activities. The pilot projects introduce new digital technologies into the nuclear plant operating environment at host operating plants to demonstrate and validate them for production usage. In turn, the pilot project technologies serve as the stepping stones to the eventual seamless digital environment as described in the Future Vision.

Final Technical Progress Report Long term risk from actinides in the environment: Modes of mobility  

SciTech Connect (OSTI)

The key source of uncertainty in assessing actinide mobility is the relative importance of transport by: (1) wind erosion, (2) water erosion, and (3) vertical migration. Each of these three processes depends on several environmental factors and they compete with one another. A scientific assessment of the long-term risks associated with actinides in surface soils depends on better quantifying each of these three modes of mobility. The objective from our EMSP study was to quantify the mobility of soil actinides by wind erosion, water erosion, and vertical migration at three semiarid sites where actinide mobility is a key technical, social and legal issue. This EMSP project was the first to evaluate all three factors at a site. The approach has been to investigate both short- and long-term issues based on field and lab studies and model comparisons. Our results demonstrate the importance of incorporating threshold responses into a modeling framework that accounts for environmental factors and natural disturbances that trigger large changes in actinide mobility. The study measured erosional losses of sediment and fallout cesium (an actinide analogue) from field plots located near WIPP in 1998. The results highlight the large effect of burning as a disturbance on contaminant transport and mobility via runoff and erosion. The results show that runoff, erosion, and actinide transport are (1) strongly site specific-differences in radionuclide transport between WIPP and Rocky Flats differed by a factor of twelve because of soil and vegetation differences, and (2) are strongly impacted by disturbances such as fire, which can increase runoff, erosion, and actinide transport by more than an order of magnitude. In addition, a laboratory experiment using soil columns was conducted to investigate the vertical transport of contaminants in sandy soils. Nine columns of soil collected from the vicinity of the WIPP site were prepared. The column consisted of a piece of PVC pipe 20 cm in diameter and approximately 22 cm long. A thin ''marker layer'' of white soil was added to the top of each column followed by a thin layer of soil that had been spiked with 137Cs, cerium and lanthanum was applied to the surface. Approximately 900 cm of water (the equivalent of about 30 years of rainfall) was then applied at a rate of 3.2 L d-1. All of the activity contained in the soil core appeared to be in the top few mm of soil, i.e. there was virtually no movement of the 134Cs labeled particles. Finally, a library of object-oriented model components was created using Visual Basic to support the construction of contaminant transport models. These components greatly simplify the task of building 1- to 3- dimensional simulation models for risk assessment. The model components created under this funding were subsequently applied to help answer questions regarding risks from irrigation associated with potential releases from the Yucca Mountain waste repository.

Grand Challenges for Biological and Environmental Research: A Long-Term Vision  

SciTech Connect (OSTI)

The interactions and feedbacks among plants, animals, microbes, humans, and the environment ultimately form the world in which we live. This world is now facing challenges from a growing and increasingly affluent human population whose numbers and lifestyles are driving ever greater energy demand and impacting climate. These and other contributing factors will make energy and climate sustainability extremely difficult to achieve over the 20-year time horizon that is the focus of this report. Despite these severe challenges, there is optimism that deeper understanding of our environment will enable us to mitigate detrimental effects, while also harnessing biological and climate systems to ensure a sustainable energy future. This effort is advanced by scientific inquiries in the fields of atmospheric chemistry and physics, biology, ecology, and subsurface science - all made possible by computing. The Office of Biological and Environmental Research (BER) within the Department of Energy's (DOE) Office of Science has a long history of bringing together researchers from different disciplines to address critical national needs in determining the biological and environmental impacts of energy production and use, characterizing the interplay of climate and energy, and collaborating with other agencies and DOE programs to improve the world's most powerful climate models. BER science focuses on three distinct areas: (1) What are the roles of Earth system components (atmosphere, land, oceans, sea ice, and the biosphere) in determining climate? (2) How is the information stored in a genome translated into microbial, plant, and ecosystem processes that influence biofuel production, climate feedbacks, and the natural cycling of carbon? (3) What are the biological, geochemical, and physical forces that govern the behavior of Earth's subsurface environment? Ultimately, the goal of BER science is to support experimentation and modeling that can reliably predict the outcomes and behaviors of complex biological and environmental systems, leading to robust solutions for DOE missions and strategic goals. In March 2010, the Biological and Environmental Research Advisory Committee held the Grand Challenges for Biological and Environmental Research: A Long-Term Vision workshop to identify scientific opportunities and grand challenges for BER science in the coming decades and to develop an overall strategy for drafting a long-term vision for BER. Key workshop goals included: (1) Identifying the greatest scientific challenges in biology, climate, and the environment that DOE will face over a 20-year time horizon. (2) Describing how BER should be positioned to address those challenges. (3) Determining the new and innovative tools needed to advance BER science. (4) Suggesting how the workforce of the future should be trained in integrative system science. This report lays out grand research challenges for BER - in biological systems, climate, energy sustainability, computing, and education and workforce training - that can put society on a path to achieve the scientific evidence and predictive understanding needed to inform decision making and planning to address future energy needs, climate change, water availability, and land use.

Long Term Storage with Surveillance of Canadian Prototype Nuclear Power Reactors  

SciTech Connect (OSTI)

Atomic Energy of Canada (AECL) was originally formed by the government of Canada in 1952 to perform research in radiation and nuclear areas. In the mid 1950's Canada decided to limit itself to peaceful uses of nuclear energy and AECL embarked on several research and development programs, one of them being the development of nuclear power plants. This led to the development of the CANDU{sup TM} design of heavy water power reactors, of which there are now 29 operating around the world. This presentation discusses the present state of the first two CANDU{sup TM} prototype reactors and a prototype boiling light water reactor and lessons learnt after being in a long-term storage with surveillance state for more than 20 years. AECL facilities undergo decommissioning by either a prompt or a deferred removal approach. Both approaches are initiated after an operating facility has been declared redundant and gone through final operational shutdown. For the deferred approach, initial decommissioning activities are performed to put the facility into a sustainable, safe, shutdown state to minimize the hazards and costs of the ensuing extended storage with surveillance (SWS) or Safestor phase. At the appropriate time, the facility is dismantled and removed, or put into a suitable condition for re-use. AECL has a number of facilities that were built during its history, and some of these are now redundant or will become redundant in the near future. The deferred removal approach is part of AECL's decommissioning strategy for several reasons: 1. Reduction in radiation doses to workers during the final dismantling, 2. No facilities are available yet in Canada for the management of quantity of wastes arising from decommissioning, 3. Financial constraints presented by the number of facilities that will undergo decommissioning, compared to the availability of funds to carry out the work. This has led to the development of a comprehensive decommissioning plan that includes all of AECL's redundant and presently operating facilities. Several significant issues have arisen over the decades these reactors have been in the SWS phase. With the long time frames encompassed by this approach to decommissioning, the storage and maintenance of facility information for future decommissioning, and the knowledge and training of successive generations of staff to perform facility inspections and maintenance are major issues. Complacency of both staff and management is a potential issue. The problem arises primarily because these facilities have been put into a comparatively low hazard state, are remotely located, and not much changes over time and changes are slow. During the period that these facilities have been in this state, regulatory scrutiny and expectations have increased. This along with continuing changes in regulatory staff requires a continuous education and communication activity with the regulator. Because of the long time frames involved, the building structures continue to deteriorate slowly, and repairs and maintenance are required upon occasion. The costs can be significant, for example, to replace a roof. When these occasions arise, the balance of cost and benefit is always questioned, i.e., 'Wouldn't it be better to spend the money on dismantling rather than fixing?'. One positive note is that ancillary buildings that either have very low radiation hazards or were decontaminated during the initial decommissioning activities have been used for several alternate uses. This has helped to defray costs, and also keeps an interest in maintaining the building structures and systems in good condition during the SWS phase. Over the past few years, the lessons learnt from these and other facilities in SWS, have been addressed in a holistic manner by moving from a short-term, project-oriented approach to a comprehensive, long term stewardship approach. Key to this approach was the development of an integrated plan to decommission all of AECL's facilities. One of the prime results of the implementation of this plan was the development of an organiza

Long-term Cardiac Mortality After Hypofractionated Radiation Therapy in Breast Cancer  

SciTech Connect (OSTI)

Purpose: To explore very-long-term mortality from ischemic heart disease (IHD) after locoregional radiation therapy of breast cancer (BC) in relation to degree of hypofractionation and other treatment variables. Methods and Materials: Two hypofractionated regimens used for locoregional radiation therapy for BC from 1975 to 1991 were considered. Patients received 4.3 Gy 2/week (10 fractions; target dose 43 Gy; n=1107) or 2.5 Gy 5/week (20 fractions; target dose 50 Gy; n=459). To estimate cardiac doses, radiation fields were reconstructed in a planning system. Time to death from IHD was the endpoint, comparing the groups with each other and with age-matched, cancer-free control individuals, modeled with the Cox proportional hazards model. Results: Patients given 4.3 Gy 10 had an increased risk of dying of IHD compared with both the 2.5 Gy group (hazard ratio [HR] = 2.37; 95% confidence interval [CI]: 1.06-5.32; P=.036) and the control group (HR = 1.59; 95% CI: 1.13-2.23; P=.008). Photon beams for parasternal fields gave an increased risk of dying of IHD compared with electron beams (HR = 2.56; 95% CI: 1.12-5.84; P=.025). Multivariate analysis gave an increased risk for the 4.3-Gy versus 2.5-Gy regimen with borderline significance (HR = 2.90; 95% CI: 0.97-8.79; P=.057) but not for parasternal irradiation. Conclusions: The degree of hypofractionation and parasternal photon beams contributed to increased cardiac mortality in this patient cohort. Differences emerged after 12 to 15 years, indicating the need of more studies with observation time of 2 decades.

Supercement for Annular Seal and Long-Term Integrity in Deep, Hot Wells "DeepTrek"  

SciTech Connect (OSTI)

The purpose of this project is to formulate a 'Supercement' designed for improving the long-term sealing integrity in HPHT wells. Phase I concentrated on chemistry studies and screening tests to design and evaluate Portland-based, hybrid Portland, and non-Portland-based cement systems suitable for further scale-up testing. Phase II work concentrated on additional lab and field testing to reduce the candidate materials list to two systems, as well as scaleup activities aimed at verifying performance at the field scale. Phase II was extended thorough a proposal to develop additional testing capabilities aimed at quantifying cementing material properties and performance that were previously not possible. Phase III focused on bringing the material(s) developed in previous Phases to commercialization, through Field Trials, Cost/Benefit Analysis, and Technology Transfer. Extensive development and testing work throughout the project led to Phase III commercialization of two very different materials: (1) Highly-expansive cement (Portland-based), patent pending as 'PRESTRESSED CEMENT'; and (2) Epoxy Resin (non-Portland-based), patent pending. Trade name is Ultra Seal-R. In Phase III, work concentrated on application of the Supercement materials in various increasingly-challenging wells. Previous testing revealed that PRESTRESSED CEMENT, when applied in weak or unconsolidated formations, tends to expand away from the central pipe, restricting the applicability of this material to competent formations. Tests were devised to quantify this effect so the material could be applied in appropriate wells. Additionally, the testing was needed because of industry resistance to expansive cements, due to previous marketing attempts with other materials that were less than successful. Field trials with the Epoxy Resin currently numbers in the hundreds of jobs at up to 295 deg F, with a large percentage being completely successful. Both the PRESTRESSED CEMENT as well as the Ultra Seal-R represent materials fulfilling the objectives of the DeepTrek project.

PROJECTED IMPACT OF SULFATE ATTACK ON THE LONG-TERM PERFORMANCE OF A CONCRETE REPOSITORY  

SciTech Connect (OSTI)

Saltstone is a cementitious waste form made by mixing salt solution originating from liquid waste storage tanks at the DOE Savannah River Site with a dry mix containing blast furnace slag, fly ash, and cement or lime. The wet mix is poured into a concrete repository for on-site disposal. Solidified Saltstone is a dense, alkaline, reducing, micro-porous, monolithic, cementitious matrix, containing a solution of salts within its pore structure. Sodium sulfate concentrations in the pore fluid are around 0.15 mol/L, and external sulfate attack on concrete barriers is expected to occur over time. To predict the long-term performance of concrete repositories, the STADIUM{reg_sign} code was used to simulate the reactive transport processes leading to formation of ettringite, an expansive mineral phase often associated with spalling or cracking. STADIUM{reg_sign} is a multi-ionic transport model based on a split operator approach that separates ionic movement and chemical reactions. Ionic transport is described by the extended Nernst-Planck equation for unsaturated media, and accounts for electrical coupling between ionic species, chemical activity, transport due to water content gradient, and temperature effects. STADIUM{reg_sign} does not predict whether physical damage will occur, or the impact on transport properties should fracturing occur. Thus the presence of ettringite was assumed to coincide with physical damage for the purpose of estimating effective transport properties. Effective properties for concrete barriers were estimated assuming complete hydraulic failure behind the ettringite front and unaltered properties ahead of the front. The ettringite front advances at a rate dependent on the diffusion coefficient assumed for the failed zone. A sensitivity study indicates a service life ranging from thousands to tens of thousands of years, depending on the barrier thickness and sulfate exposure conditions among other factors.

Lipidomic changes in rat liver after long-term exposure to ethanol  

SciTech Connect (OSTI)

Alcoholic liver disease (ALD) is a serious health problem with significant morbidity and mortality. In this study we examined the progression of ALD along with lipidomic changes in rats fed ethanol for 2 and 3 months to understand the mechanism, and identify possible biomarkers. Male Fischer 344 rats were fed 5% ethanol or caloric equivalent of maltose-dextrin in a Lieber-DeCarli diet. Animals were killed at the end of 2 and 3 months and plasma and livers were collected. Portions of the liver were fixed for histological and immunohistological studies. Plasma and the liver lipids were extracted and analyzed by nuclear magnetic resonance (NMR) spectroscopy. A time dependent fatty infiltration was observed in the livers of ethanol-fed rats. Mild inflammation and oxidative stress were observed in some ethanol-fed rats at 3 months. The multivariate and principal component analysis of proton and phosphorus NMR spectroscopy data of extracted lipids from the plasma and livers showed segregation of ethanol-fed groups from the pair-fed controls. Significant hepatic lipids that were increased by ethanol exposure included fatty acids and triglycerides, whereas phosphatidylcholine (PC) decreased. However, both free fatty acids and PC decreased in the plasma. In liver lipids unsaturation of fatty acyl chains increased, contrary to plasma, where it decreased. Our studies confirm that over-accumulation of lipids in ethanol-induced liver steatosis accompanied by mild inflammation on long duration of ethanol exposure. Identified metabolic profile using NMR lipidomics could be further explored to establish biomarker signatures representing the etiopathogenesis, progression and/or severity of ALD. - Highlights: > Long term exposure to ethanol was studied. > A nuclear magnetic resonance (NMR) spectroscopy based lipidomic approach was used. > We examined the clustering pattern of the NMR data with principal component analysis. > NMR data were compared with histology and immunohistochemistry data. > Biochemical parameters were compared with the observed NMR lipid data.

Evaluation of the long-term environmental performance of Greek lignite-fired power stations  

Science Journals Connector (OSTI)

Abstract At national, regional and global level, there is no doubt that the electric generation from fossil fuel-fired power plants is one of the greatest causes of air pollution and climate change. However, fossil fuels contribute more than 70% in the planet electricity generation during the last 30 years. In Greece, lignite is the only proved significant indigenous fossil fuel source, currently representing about 50% of the national electricity generation (a situation which is not expected to change dramatically in the near future). As a result, owed to the use of local lignite reserves (poor quality lignite), the Greek Lignite Thermal Power Stations (LTPSs) are responsible for the production of significant airborne emissions and particle releases (e.g. CO2, SO2, NOX, PM). At the same time, Greece, on top of the Kyoto Protocol, has accepted specific obligations and incorporated into its national legislation several air quality Directives concerning the reduction of various harmful gases and particle releases attributed to fossil fuel combustion. Thus, wide scrutiny of concentration time series of all these airborne emissions constitutes an important indicator of the current technology used, considering at the same time that any violation noted should be the object of serious national concern. Under this argument, the current work presents and evaluates the long-term environmental performance of the Greek lignite-based electricity generation system as far as CO2, NOX, SO2 and PM are concerned up to the year 2011. According to the results obtained, one may rank the operating \\{LTPSs\\} according to their environmental performance giving to the Greek society the necessary tools to determine their utilisation factor on top of the techno-economic criteria used up to now.

Long-term Clinical Outcomes of Whole-Breast Irradiation Delivered in the Prone Position  

SciTech Connect (OSTI)

Purpose: The aim of this study was to evaluate retrospectively the effectiveness and toxicity of post-lumpectomy whole-breast radiation therapy delivered with prone positioning. Methods and Materials: Between September 1992 and August 2004, 245 women with 248 early-stage invasive or in situ breast cancers were treated using a prone breast board. Photon fields treated the whole breast to 46 to 50.4 Gy with standard fractionation. The target volume was clinically palpable breast tissue; no attempt was made to irradiate chest wall lymphatics. Tumor bed boosts were delivered in 85% of cases. Adjuvant chemotherapy and hormonal therapy were administered to 42% and 62% of patients, respectively. Results: After a median follow-up of 4.9 years, the 5 year actuarial true local and elsewhere ipsilateral breast tumor recurrence rates were 4.8% and 1.3%, respectively. The 5-year actuarial rates of regional nodal recurrence and distant metastases were 1.6% and 7.4%. Actuarial disease-free, disease-specific, and overall survival rates at 5 years were 89.4%, 97.3%, and 93%, respectively. Treatment breaks were required by 2.4% of patients. Grade 3 acute dermatitis and edema were each limited to 2% of patients. Only 4.9% of patients complained of acute chest wall discomfort. Chronic Grade 2 to 3 skin and subcutaneous tissue toxicities were reported in 4.4% and 13.7% of patients, respectively. Conclusions: Prone position breast radiation results in similar long-term disease control with a favorable toxicity profile compared with standard supine tangents. The anatomic advantages of prone positioning may contribute to improving the therapeutic ratio of post-lumpectomy radiation by improving dose homogeneity and minimizing incidental cardiac and lung dose.

Low-level waste management in the South. Task 4. 2 - long-term care requirements. [Shallow land burial  

SciTech Connect (OSTI)

This paper provides an analysis of the long-term care requirements of low-level radioactive waste disposal facilities. Among the topics considered are the technical requirements for long-term care, the experiences of the three inactive and three active commercial disposal facilities concerning perpetual care and maintenance, and the financial management of a perpetual care fund. In addition, certain recommendations for the establishment of a perpetual care fund are provided. The predominant method of disposing of low-level radioactive wastes is shallow land burial. After studying alternative methods of disposal, the U.S Nuclear Regulatory Commission (NRC) concluded that there are no compelling reasons for abandoning this disposal method. Of the 22 shallow land burial facilities in the U.S., the federal government maintains 14 active and two inactive disposal sites. There are three active (Barnwell, South Carolina; Hanford, Washington; and Beatty, Nevada) and three inactive commercial disposal facilities (Maxey Flats, Kentucky; Sheffield, Illinois; and West Valley, New York). The life of a typical facility can be broken into five phases: preoperational, operational, closure, postclosure observation and maintenance, and institutional control. Long-term care of a shallow land burial facility will begin with the disposal site closure phase and continue through the postclosure observation and maintenance and institutional control phases. Since the postclosure observation and maintenance phase will last about five years and the institutional control phase 100 years, the importance of a well planned long-term care program is apparent. 26 references, 1 table.

A hierarchical approach for online temporal lobe seizure detection in long-term intracranial EEG recordings  

Science Journals Connector (OSTI)

Objective. Around 1% of the world's population is affected by epilepsy, and nearly 25% of patients cannot be treated effectively by available therapies. The presence of closed-loop seizure-triggered stimulation provides a promising solution for these patients. Realization of fast, accurate, and energy-efficient seizure detection is the key to such implants. In this study, we propose a two-stage on-line seizure detection algorithm with low-energy consumption for temporal lobe epilepsy (TLE). Approach. Multi-channel signals are processed through independent component analysis and the most representative independent component (IC) is automatically selected to eliminate artifacts. Seizure-like intracranial electroencephalogram (iEEG) segments are fast detected in the first stage of the proposed method and these seizures are confirmed in the second stage. The conditional activation of the second-stage signal processing reduces the computational effort, and hence energy, since most of the non-seizure events are filtered out in the first stage. Main results. Long-term iEEG recordings of 11 patients who suffered from TLE were analyzed via leave-one-out cross validation. The proposed method has a detection accuracy of 95.24%, a false alarm rate of 0.09/h, and an average detection delay time of 9.2s. For the six patients with mesial TLE, a detection accuracy of 100.0%, a false alarm rate of0.06/h, and an average detection delay time of 4.8s can be achieved. The hierarchical approach provides a 90% energy reduction, yielding effective and energy-efficient implementation for real-time epileptic seizure detection. Significance. An on-line seizure detection method that can be applied to monitor continuous iEEG signals of patients who suffered from TLE was developed. An IC selection strategy to automatically determine the most seizure-related IC for seizure detection was also proposed. The system has advantages of (1) high detection accuracy, (2) low false alarm, (3) short detection latency, and (4) energy-efficient design for hardware implementation.

MICROSTRUCTURE OF LONG-TERM AGED IN617 NI-BASE SUPERALLOY  

SciTech Connect (OSTI)

The microstructure of the Ni-base superalloy IN617 that had undergone prolonged aging (approximately 65,000 hours) at a series of temperatures from 482 C to 871 C has been characterized by microhardness measurements, optical microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Cr23C6, Mo-rich eta-M6C, and Ti(C,N) constitute the major primary coarse precipitates both within the grains and along the grain boundaries. The secondary carbides were mostly fine Cr23C6, which had a cube-on-cube orientation relationship (OR) with the fcc matrix, and at long times were present in cuboidal and plate-shape forms within the grains and as films along the grain boundaries. Fine, eta-M6C carbides were also observed at low to intermediate temperatures with an OR given by [011] carbide//[011] matrix, carbide// matrix. The coarse eta-M6C carbides increased in extent at 871 C, whereas the counterpart fine carbides were absent. The phase was found to be present at all aging temperatures up to 871 C, with a volume fraction ranging from very low to approximately 5 pct at 593 C, where the peak in microhardness occurs. The observations have also suggested that the presence of a very small amount of at temperatures as high as 871 C at long times may be associated with a reaction between the fine eta-carbides and the matrix. Ultrafine precipitates of the intermetallic phase Ni2(Cr,Mo) with the Pt2Mo-type structure was observed in addition to in samples aged for 28,300 hours at the lowest aging temperature of 482 C. These precipitates were absent in samples aged at higher temperatures. The various observations made have suggested that the long-term thermal stability of the IN617 alloy is reasonably good over a wide temperature range of 538 C to 704 C, whereas at higher temperatures (871 C), the substantial decrease in the volume fraction of and coarsening and clustering of the carbides lead to a large drop in the microhardness. A modified time-temperature-transformation (TTT) diagram was constructed based on the results of this study and comparison with previous reports.

Nuclear Waste Disposal and Strategies for Predicting Long-Term Performance of Material  

SciTech Connect (OSTI)

Ceramics have been an important part of the nuclear community for many years. On December 2, 1942, an historic event occurred under the West Stands of Stagg Field, at the University of Chicago. Man initiated his first self-sustaining nuclear chain reaction and controlled it. The impact of this event on civilization is considered by many as monumental and compared by some to other significant events in history, such as the invention of the steam engine and the manufacturing of the first automobile. Making this event possible and the successful operation of this first man-made nuclear reactor, was the use of forty tons of UO2. The use of natural or enriched UO2 is still used today as a nuclear fuel in many nuclear power plants operating world-wide. Other ceramic materials, such as 238Pu, are used for other important purposes, such as ceramic fuels for space exploration to provide electrical power to operate instruments on board spacecrafts. Radioisotopic Thermoelectric Generators (RTGs) are used to supply electrical power and consist of a nuclear heat source and converter to transform heat energy from radioactive decay into electrical power, thus providing reliable and relatively uniform power over the very long lifetime of a mission. These sources have been used in the Galileo spacecraft orbiting Jupiter and for scientific investigations of Saturn with the Cassini spacecraft. Still another very important series of applications using the unique properties of ceramics in the nuclear field, are as immobilization matrices for management of some of the most hazardous wastes known to man. For example, in long-term management of radioactive and hazardous wastes, glass matrices are currently in production immobilizing high-level radioactive materials, and cementious forms have also been produced to incorporate low level wastes. Also, as part of nuclear disarmament activities, assemblages of crystalline phases are being developed for immobilizing weapons grade plutonium, to not only produce environmentally friendly products, but also forms that are proliferation resistant. All of these waste forms as well as others, are designed to take advantage of the unique properties of the ceramic systems.

Evaluation of a deposit in the vicinity of the PBU L-106 Site, North Slope, Alaska, for a potential long-term test of gas production from hydrates  

SciTech Connect (OSTI)

As part of the effort to investigate the technical feasibility of gas production from hydrate deposits, a long-term field test (lasting 18-24 months) is under consideration in a project led by the U.S. Department of Energy. We evaluate a candidate deposit involving the C-Unit in the vicinity of the PBU-L106 site in North Slope, Alaska. This deposit is stratigraphically bounded by impermeable shale top and bottom boundaries (Class 3), and is characterized by high intrinsic permeabilities, high porosity, high hydrate saturation, and a hydrostatic pressure distribution. The C-unit deposit is composed of two hydrate-bearing strata separated by a 30-ft-thick shale interlayer, and its temperatrure across its boundaries ranges between 5 and 6.5 C. We investigate by means of numerical simulation involving very fine grids the production potential of these two deposits using both vertical and horizontal wells. We also explore the sensitivity of production to key parameters such as the hydrate saturation, the formation permeability, and the permeability of the bounding shale layers. Finally, we compare the production performance of the C-Unit at the PBU-L106 site to that of the D-Unit accumulation at the Mount Elbert site, a thinner, single-layer Class 3 deposit on the North Slope of Alaska that is shallower, less-pressurized and colder (2.3-2.6 C). The results indicate that production from horizontal wells may be orders of magnitude larger than that from vertical ones. Additionally, production increases with the formation permeability, and with a decreasing permeability of the boundaries. The effect of the hydrate saturation on production is complex and depends on the time frame of production. Because of higher production, the PBU-L106 deposit appears to have an advantage as a candidate for the long-term test.

Designing Program Roadmaps to Catalyze Community Formation: A Case Study of the Long-Term Stewardship Science and Technology Roadmapword  

SciTech Connect (OSTI)

A number of broad perspective technology roadmaps have been developed in the last few years as tools for coordinating nation-wide research in targeted areas. These roadmaps share a common characteristic of coalescing the associated stakeholder groups into a special-interest community that is willing to work cooperatively in achieving the roadmap goals. These communities are key to roadmap implementation as they provide the collaborative energy necessary to obtain the political support and funding required for identified science and technology development efforts. This paper discusses the relationship between roadmaps and special-interest communities, using the recently drafted Department of Energy's Long-Term Stewardship Science and Technology Roadmap as a case study. Specific aspects this roadmap's design facilitated the development of a long-term stewardship community while specific realities during roadmap development impacted the realization of the design.
