Electric Bike Sharing--System Requirements and Operational Concepts  

DOE Green Energy (OSTI)

Bike sharing is an exciting new model of public-private transportation provision that has quickly emerged in the past five years. Technological advances have overcome hurdles of early systems and cities throughout the globe are adopting this model of transportation service. Electric bikes have simultaneously gained popularity in many regions of the world and some have suggested that shared electric bikes could provide an even higher level of service compared to existing systems. There are several challenges that are unique to shared electric bikes: electric-assisted range, recharging protocol, and bike and battery checkout procedures. This paper outlines system requirements to successfully develop and deploy an electric bike sharing system, focusing on system architecture, operational concepts, and battery management. Although there is little empirical evidence, electric bike sharing could be feasible, depending on demand and battery management, and can potentially improve the utility of existing bike sharing systems. Under most documented bike sharing use scenarios, electric bike battery capacity is insufficient for a full day of operation, depending on recharging protocol. Off-board battery management is a promising solution to address this problem. Off-board battery management can also support solar recharging. Future pilot tests will be important and allow empirical evaluation of electric bikesharing system performance. (auth)

Equipment Operational Requirements  

SciTech Connect

The Iraq Department of Border Enforcement is rich in personnel, but poor in equipment. An effective border control system must include detection, discrimination, decision, tracking and interdiction, capture, identification, and disposition. An equipment solution that addresses only a part of this will not succeed, likewise equipment by itself is not the answer without considering the personnel and how they would employ the equipment. The solution should take advantage of the existing in-place system and address all of the critical functions. The solutions are envisioned as being implemented in a phased manner, where Solution 1 is followed by Solution 2 and eventually by Solution 3. This allows adequate time for training and gaining operational experience for successively more complex equipment. Detailed descriptions of the components follow the solution descriptions. Solution 1 - This solution is based on changes to CONOPs, and does not have a technology component. It consists of observers at the forts and annexes, forward patrols along the swamp edge, in depth patrols approximately 10 kilometers inland from the swamp, and checkpoints on major roads. Solution 2 - This solution adds a ground sensor array to the Solution 1 system. Solution 3 - This solution is based around installing a radar/video camera system on each fort. It employs the CONOPS from Solution 1, but uses minimal ground sensors deployed only in areas with poor radar/video camera coverage (such as canals and streams shielded by vegetation), or by roads covered by radar but outside the range of the radar associated cameras. This document provides broad operational requirements for major equipment components along with sufficient operational details to allow the technical community to identify potential hardware candidates. Continuing analysis will develop quantities required and more detailed tactics, techniques, and procedures.

Systems Modeling, Simulation and Material Operating Requirements for Chemical Hydride Based Hydrogen Storage  

Science Conference Proceedings (OSTI)

Research on ammonia borane (AB, NH3BH3) has shown it to be a promising material for chemical hydride based hydrogen storage. AB was selected by DOE's Hydrogen Storage Engineering Center of Excellence (HSECoE) as the initial chemical hydride of study because of its high hydrogen storage capacity (up to 19.6% by weight for the release of {approx}2.5 molar equivalents of hydrogen gas) and its stability under typical ambient conditions. A new systems concept based on augers, ballast tank, hydrogen heat exchanger and H2 burner was designed and implemented in simulation. In this design, the chemical hydride material was assumed to produce H2 on the augers itself, thus minimizing the size of ballast tank and reactor. One dimensional models based on conservation of mass, species and energy were used to predict important state variables such as reactant and product concentrations, temperatures of various components, flow rates, along with pressure, in various components of the storage system. Various subsystem components in the models were coded as C language S-functions and implemented in Matlab/Simulink environment. The control variable AB (or alane) flow rate was determined through a simple expression based on the ballast tank pressure, H2 demand from the fuel cell and hydrogen production from AB (or alane) in the reactor. System simulation results for solid AB, liquid AB and alane for both steady state and transient drive cycle cases indicate the usefulness of the model for further analysis and prototype development.

Performance Optimization of a Fan System- Overcoming Impacts of Modified Design Criteria Due to Regulatory Requirements and Changed Operating Conditions  

E-Print Network (OSTI)

The Louisiana Pacific mill in Tomahawk Wisconsin manufactures oriented-strand board. Several large induced-draft fans and combustion-air blowers were operating inefficiently at this mill. This case study highlights a systems approach that was applied to address fan inefficiency. Energy savings from optimizing the system are estimated to be 338 kW, nearly half of the original measured input power of 678 kW. The project is currently being implemented and will have a payback period of less than 8 months. The opportunities here are typical of opportunities thought to exist in most industrial plants. In this case, process needs changed due to environmental regulations and change of location, but the system did not, leading to low overall system efficiency.

Transportation System Concept of Operations  

Science Conference Proceedings (OSTI)

The Nuclear Waste Policy Act of 1982 (NWPA), as amended, authorized the DOE to develop and manage a Federal system for the disposal of SNF and HLW. OCRWM was created to manage acceptance and disposal of SNF and HLW in a manner that protects public health, safety, and the environment; enhances national and energy security; and merits public confidence. This responsibility includes managing the transportation of SNF and HLW from origin sites to the Repository for disposal. The Transportation System Concept of Operations is the core high-level OCRWM document written to describe the Transportation System integrated design and present the vision, mission, and goals for Transportation System operations. By defining the functions, processes, and critical interfaces of this system early in the system development phase, programmatic risks are minimized, system costs are contained, and system operations are better managed, safer, and more secure. This document also facilitates discussions and understanding among parties responsible for the design, development, and operation of the Transportation System. Such understanding is important for the timely development of system requirements and identification of system interfaces. Information provided in the Transportation System Concept of Operations includes: the functions and key components of the Transportation System; system component interactions; flows of information within the system; the general operating sequences; and the internal and external factors affecting transportation operations. The Transportation System Concept of Operations reflects OCRWM's overall waste management system policies and mission objectives, and as such provides a description of the preferred state of system operation. The description of general Transportation System operating functions in the Transportation System Concept of Operations is the first step in the OCRWM systems engineering process, establishing the starting point for the lower level descriptions. of subsystems and components, and the Transportation System Requirements Document. Other program and system documents, plans, instructions, and detailed designs will be consistent with and informed by the Transportation System Concept of Operations. The Transportation System Concept of Operations is a living document, enduring throughout the OCRWM systems engineering lifecycle. It will undergo formal approval and controlled revisions as appropriate while the Transportation System matures. Revisions will take into account new policy decisions, new information available through system modeling, engineering investigations, technical analyses and tests, and the introduction of new technologies that can demonstrably improve system performance.

Managing System of Systems Requirements with a Requirements Screening Group  

SciTech Connect

Figuring out an effective and efficient way to manage not only your Requirement’s Baseline, but also the development of all your individual requirements during a Program’s/Project’s Conceptual and Development Life Cycle Stages can be both daunting and difficult. This is especially so when you are dealing with a complex and large System of Systems (SoS) Program with potentially thousands and thousands of Top Level Requirements as well as an equal number of lower level System, Subsystem and Configuration Item requirements that need to be managed. This task is made even more overwhelming when you have to add in integration with multiple requirements’ development teams (e.g., Integrated Product Development Teams (IPTs)) and/or numerous System/Subsystem Design Teams. One solution for tackling this difficult activity on a recent large System of Systems Program was to develop and make use of a Requirements Screening Group (RSG). This group is essentially a Team made up of co-chairs from the various Stakeholders with an interest in the Program of record that are enabled and accountable for Requirements Development on the Program/Project. The RSG co-chairs, often with the help of individual support team, work together as a Program Board to monitor, make decisions on, and provide guidance on all Requirements Development activities during the Conceptual and Development Life Cycle Stages of a Program/Project. In addition, the RSG can establish and maintain the Requirements Baseline, monitor and enforce requirements traceability across the entire Program, and work with other elements of the Program/Project to ensure integration and coordination.

Operational Experience with the CEBAF Control System  

SciTech Connect

This paper describes our operational experience with the CEBAF control system. CEBAF is operated using a variety of software packages and custom applications. In the spirit of collaboration and software sharing, the current system utilizes code developed at four major laboratories as well as commercial packages and custom applications. The basis of the CEBAF control system is EPICS (Experimental Physics and Industrial Control System), originally developed at LANL and ANL. The CEBAF accelerator is operated primarily using the common EPICS tools such as the archiver, alarm handler and display manager. In order to supplement the features of EPICS, custom applications have been developed and incorporated into the control system using C, C++, and TCL. Additionally, the CEBAF helium plant is controlled using the CEBAF TACL system which requires communications between the two control systems. CATER, a problem tracking program developed at SLAC, has also been integrated into the operational software. Current plans call for the integration of an on-line logbook developed at APS and the internal development of a down-time logger program. We discuss how these various tools and applications are used operationally, the advantages and disadvantages of the systems and the challenges related to integrating this diverse array of software.

Evaluating Utility System Operations Using APLUS  

E-Print Network (OSTI)

The steam system at a recycled paper fiberboard plant in Texas was evaluated using APLUS. These simulations identified inefficiencies in the current operation and so suggested more efficient alternatives. The information provided by the client was used to develop heat and mass balances for the base case. The marginal cost analysis in APLUS was used to identify the high cost areas in operating the steam system. This analysis highlighted that the cost of power from the 200 psig steam driven back pressure turbine was a prohibitive $270/MWh. The 600 psig boiler and extraction turbine were found to be large enough to meet all the steam and power requirements of the plant. This required that a new 600 HP motor be bought to drive the paper machine currently driven by the back pressure turbine. Shifting the load in this manner resulted in annual savings of $590,000.

Nuclear Power - System Simulations and Operation  

E-Print Network (OSTI)

At the onset of the 21st century, we are searching for reliable and sustainable energy sources that have a potential to support growing economies developing at accelerated growth rates, technology advances improving quality of life and becoming available to larger and larger populations. The quest for robust sustainable energy supplies meeting the above constraints leads us to the nuclear power technology. Today's nuclear reactors are safe and highly efficient energy systems that offer electricity and a multitude of co-generation energy products ranging from potable water to heat for industrial applications. Catastrophic earthquake and tsunami events in Japan resulted in the nuclear accident that forced us to rethink our approach to nuclear safety, requirements and facilitated growing interests in designs, which can withstand natural disasters and avoid catastrophic consequences. This book is one in a series of books on nuclear power published by InTech. It consists of ten chapters on system simulations and operational aspects. Our book does not aim at a complete coverage or a broad range. Instead, the included chapters shine light at existing challenges, solutions and approaches. Authors hope to share ideas and findings so that new ideas and directions can potentially be developed focusing on operational characteristics of nuclear power plants. The consistent thread throughout all chapters is the system-thinking approach synthesizing provided information and ideas. The book targets everyone with interests in system simulations and nuclear power operational aspects as its potential readership groups - students, researchers and practitioners.

Prediction of Power System Balancing Requirement and Tail Event  

Science Conference Proceedings (OSTI)

This paper presents a methodology for the prediction of power system balancing requirement and the probability of tail event (large imbalance between generation and load). Maintaining sufficient balancing reserves to match the difference between hourly generation schedule and real-time variable load and intermittent resources, becomes more and more challenging with the increasing penetration of intermittent energy sources. The presented methodology uses a yearly distribution and an hourly distribution of balancing requirement and tail events to provide a high level look at the issue and warn system operators of those hours when problems are most likely to occur. For real-time prediction, a Bayes Net model is constructed to model the statistical relationships between system imbalance and forecast errors, generation schedule control errors and other influential factors. The methodology will be able to provide reference information to system operators in determining the sufficiency of system balancing reserve and taking appropriate control actions.

Smart Grid - Transforming Power System Operations  

SciTech Connect

Abstract—Electric power systems are entering a new realm of operations. Large amounts of variable generation tax our ability to reliably operate the system. Couple this with a greater reliance on the electricity network to serve consumer demand that is likely to rise significantly even as we drive for greater efficiency. Trade-offs between energy and environmental needs will be constantly negotiated, while a reliable supply of electricity needs even greater assurance in a world where threats of disruption have risen. Smart grid capabilities are being proposed to help address the challenges confronting system operations. This paper reviews the impact of smart grid functionality on transforming power system operations. It explores models for distributed energy resources (DER – generation, storage, and load) that are appearing on the system. It reviews the evolving nature of electricity markets to deal with this complexity and a change of emphasis on signals from these markets to affect power system control. Smart grid capabilities will also impact reliable operations, while cyber security issues must be addressed as a culture change that influences all system design, implementation, and maintenance. Lastly, the paper explores significant questions for further research and the need for a simulation environment that supports such investigation and informs deployments to mitigate operational issues as they arise.

Methodology for assessing systems materials requirements  

SciTech Connect

A potential stumbling block to new system planning and design is imprecise, confusing, or contradictory data regarding materials - their availability and costs. A methodology is now available that removes this barrier by minimizing uncertainties regarding materials availability. Using this methodology, a planner can assess materials requirements more quickly, at lower cost, and with much greater confidence in the results. Developed specifically for energy systems, its potential application is much broader. This methodology and examples of its use are discussed.

Naturalistic Decision Making for Power System Operators  

Science Conference Proceedings (OSTI)

Motivation – Investigations of large-scale outages in the North American interconnected electric system often attribute the causes to three T’s: Trees, Training and Tools. To document and understand the mental processes used by expert operators when making critical decisions, a naturalistic decision making (NDM) model was developed. Transcripts of conversations were analyzed to reveal and assess NDM-based performance criteria. Findings/Design – An item analysis indicated that the operators’ Situation Awareness Levels, mental models, and mental simulations can be mapped at different points in the training scenario. This may identify improved training methods or analytical/ visualization tools. Originality/Value – This study applies for the first time, the concepts of Recognition Primed Decision Making, Situation Awareness Levels and Cognitive Task Analysis to training of electric power system operators. Take away message – The NDM approach provides a viable framework for systematic training management to accelerate learning in simulator-based training scenarios for power system operators and teams.

Naturalistic Decision Making For Power System Operators  

Science Conference Proceedings (OSTI)

Abstract: Motivation -- As indicated by the Blackout of 2003, the North American interconnected electric system is vulnerable to cascading outages and widespread blackouts. Investigations of large scale outages often attribute the causes to the three T’s: Trees, Training and Tools. A systematic approach has been developed to document and understand the mental processes that an expert power system operator uses when making critical decisions. The approach has been developed and refined as part of a capability demonstration of a high-fidelity real-time power system simulator under normal and emergency conditions. To examine naturalistic decision making (NDM) processes, transcripts of operator-to-operator conversations are analyzed to reveal and assess NDM-based performance criteria. Findings/Design -- The results of the study indicate that we can map the Situation Awareness Level of the operators at each point in the scenario. We can also identify clearly what mental models and mental simulations are being performed at different points in the scenario. As a result of this research we expect that we can identify improved training methods and improved analytical and visualization tools for power system operators. Originality/Value -- The research applies for the first time, the concepts of Recognition Primed Decision Making, Situation Awareness Levels and Cognitive Task Analysis to training of electric power system operators. Take away message -- The NDM approach provides an ideal framework for systematic training management and mitigation to accelerate learning in team-based training scenarios with high-fidelity power grid simulators.

Operational experience with the CEBAF control system  

SciTech Connect

The CEBAF accelerator at Thomas Jefferson National Accelerator Facility (Jefferson Lab) successfully began its experimental nuclear physics program in November of 1995 and has since surpassed predicted machine availability. Part of this success can be attributed to using the EPICS (Experimental Physics and Industrial Control System) control system toolkit. The CEBAF control system is one of the largest accelerator control system now operating. It controls approximately 338 SRF cavities, 2,300 magnets, 500 beam position monitors and other accelerator devices, such as gun hardware and other beam monitoring devices. All told, the system must be able to access over 125,000 database records. The system has been well received by both operators and the hardware designers. The EPICS utilities have made the task of troubleshooting systems easier. The graphical and test-based creation tools have allowed operators to custom build control screens. In addition, the ability to integrate EPICS with other software packages, such as Tcl/Tk, has allowed physicists to quickly prototype high-level application programs, and to provide GUI front ends for command line driven tools. Specific examples of the control system applications are presented in the areas of energy and orbit control, cavity tuning and accelerator tune up diagnostics.

Utility market and requirements for a solar thermophotovoltaic system  

Science Conference Proceedings (OSTI)

There is a growing need for clean affordable electric power generation in both the U.S. and internationally and solar thermophotovoltaic (STPV) can meet the needs of this market. This paper investigates the utility grid market applicable to a solar thermophotovoltaic power generating system. It finds that a large international electrical market and a smaller U.S. electrical market exist today but the U.S. market will grow by the year 2005 to a level that would easily support the high production level required for solar systems to be cost effective. Factors which could influence this market and the system characteristics considered by utilities in selecting future power systems such as levelized energy cost, dispatchability, environmental, etc., for both the grid and remote market are discussed. The main competition for this market and the operating performance of this competition are described. A conceptual design of a STPV power system is presented, the operation is described, and how the performance meets the utility requirements is discussed. The relationship between the cost of the TPV conversion unit and the system efficiency of the STPV system is given for both the grid and remote markets that it must meet in order to be competitive. {copyright} {ital 1996 American Institute of Physics.}

Optimizing the design and operation of aquifer thermal energy systems  

DOE Green Energy (OSTI)

The design of Aquifer Thermal Energy Storage (ATES) systems is complicated by significant uncertainties in ones ability to reliably predict the response of the aquifer to fluid and thermal fluxes. Overdesigning the system, to compensate for these uncertainties, reduces the potential economic and energy benefits of an ATES system. Underdesigning the system results in systems that fail to meet design targets. Unfortunately, standard aquifer characterization methods and hydrologic models do not provide adequate information to overcome these uncertainties. Thus, expensive full-scale tests are generally recommended to develop an adequate-understanding of the systems response. However, the standard engineering {open_quotes}design-build-operate{close_quotes} process is not. appropriate for ATES systems because an optimal design cannot be completed without some operational experience, i.e., field tests. A more adaptive engineering process is required. This engineering process should be flexible enough to allow the design to be adjusted during the operation, as monitoring data become available and as an understanding of the system response increases. Engineering approaches being developed for environmental restoration of contaminated soil and groundwater can be adapted to optimally design and operate ATES systems.

Utility interface requirements for a solar power system  

DOE Green Energy (OSTI)

This study specifies that the southern tier of the US (south of the 36th parallel) should be examined to see what problems might develop with the installation of a Satellite Power System (SPS) in the year 2000. One or more 5-GW SPS units could be installed in the utility systems of the southern states in the year 2000. The 345- and 500-kV transmission systems that will probably exist at that time could be readily extended to accommodate the SPS units. The operation of the units will present the utilities with new and difficult problems in system stability and frequency control. The problems will arise because a somewhat variable 5-GW output will be produced by a generator having no mechanical inertia. The unavoidable time lag in controlling the position of the energy beam at the receiving station may have a very critical effect on the stability of the utility systems. The maintenance problems associated with the energy-receiving device, a continuous structure covering more than 40 mi/sup 2/, must be given careful consideration. Repair of lightning damage while maintaining SPS operation may be the most critical requirement. Acquisition and preparation of the 90 mi/sup 2/ land required for the receiving antenna (rectenna) will create many new and difficult environmental problems.

Solar power system requiring no active control device  

SciTech Connect

A solar power system has a photovoltaic array having a locus of peak power points for various insolation levels, a voltage-dependent variable resistance load such as a water electrolysis unit electrically connected to the array, and a demand-dependent variable resistance load such as a dc to ac inverter connected in parallel with the electrolysis unit. The electrolysis unit or other voltage-dependent variable resistance load has a voltage-current characteristic in which the operating point is displaced from the array's peak power point for most insolation levels. The characteristic is displaced towards higher voltage-lower current operating points. The inverter may move the operating point of the photovoltaic array toward its peak power point when the load requires power. The system may be designed so that the array operates within about 5 percent of its peak power point over a wide range of inverter power demands. A fuel cell may be connected in parallel with the array to provide power to the inverter at low insolation levels, at night or in low sunlight. The fuel cell may use the hydrogen produced by the electrolysis unit for fuel. The total photovoltaic power made available by the system of this invention is generally greater than 95 percent and often greater than 98 percent of the maximum power which the photovoltaic array may produce for many insolation levels.

Control System Data Management from an Operational Point of View  

SciTech Connect

Day-to-day operation of the Continuous Electron Beam Accelerator Facility (CEBAF) requires the management of over 25,000 signals on the EPICS control system. Operators need to carry out tasks such as saving the present state of the machine, restoring old machine states and rebooting IOCs. Several tools for performing data management tasks are described in this paper. The saving and restoring of signals from a user friendly GUI using the Tcl/Tk programming language is presented, along with a method for recovering from IOC reboots, both intentional and unintentional.

Photovoltaics as an operating energy system  

DOE Green Energy (OSTI)

In the short time since the discovery of the modern solar cell in 1954, terrestrial photovoltaic power system technology has matured in all areas, from collector reliability to system and subsystem design and operations. Today's PV systems are finding widespread use in powering loads where conventional sources are either unavailable, unreliable, or too costly. A broad range of applications is possible because of the modularity of the technology---it can be used to power loads ranging from less than a watt to several megawatts. This inherent modularity makes PV an excellent choice to play a major role in rural electrification in the developing world. The future for grid-connected photovoltaic systems is also very promising. Indications are that several of today's technologies, at higher production rates and in megawatt-sized installations, will generate electricity in the vicinity of $0.12/kWh in the near future. 12 refs., 3 figs.

Operation of Energy Efficient Residential Buildings Under Indoor Environmental Quality Requirements  

E-Print Network (OSTI)

This paper is devoted to the influence of Indoor Environmental Quality, [IEQ] requirements associated with occupation regimes on the criterion of energy demand s for HVAC (Heating, Ventilating and Air-Conditioning) central systems that were constructed for student hostels as a residential building in Cairo, Egypt. The paper focuses on the effects of occupation rate profiles with IEQ thermal parameters; (those are air dry-bulb temperatures, relative humidity, fresh air requirements, and local air velocities), on yearly energy demands. It is applied on, in-service, real project as a case study "10-Stories Hostel of 6000 m2 built-up area" that is utilized by Non-Local students as a transferred Egyptian citizens [ EC ] from different governorates. It was concluded that. during energy simulation, occupation rate schedules and operation profiles for each source of heat inside space shall simulate the reality. These profiles and schedules should be added to the local energy code as a guideline for designers. Although in this case study results from simulation task reach the real bills, but sometimes, with multi-use apartments there is another required schedule for the Pre-Action days. Those days before holidays and feasts on which the air conditioning system shall operate in a certain procedure for cleaning or scavenging. Another important issue is the effect of Effective Temperatures [ET] (Temperature for constant thermal sensations) that could implement to reduce the cooling capacity by increasing the room temperature against indoor relative humidity for the same comfort sensation. These two concepts will save 17% to 22% of the project total energy demand, In addition to introducing new design criteria for acceptable indoor conditions in the new rural developed zones in Egypt and similar regions.

"Overview: The article addresses the growing trend in outsourcing boiler equipment, installation, operation, maintenance and ownership by large corporations, colleges and universities. Issues: To remain competitive and provide for growth, corporations and not-for-profit (NFP) organizations have changed the way they look at their energy systems: • They are only allocating capital to ""core"" assets. In most cases, thennal, electric and air energy systems are not considered ""core"" assets resulting in the need to find ""other"" solutions to providing the needed energy. • Reduced staffing has resulted in fewer experienced and knowledgeable boiler operating and maintenance personnel. • Fluctuating energy costs make it difficult to accurately plan and budget. • Constantly changing emissions standards and regulations add operational cost burdens. Objective: Find a solution to these pressures that does not require capital investment."

Wind Speed Forecasting for Power System Operation  

E-Print Network (OSTI)

In order to support large-scale integration of wind power into current electric energy system, accurate wind speed forecasting is essential, because the high variation and limited predictability of wind pose profound challenges to the power system operation in terms of the efficiency of the system. The goal of this dissertation is to develop advanced statistical wind speed predictive models to reduce the uncertainties in wind, especially the short-term future wind speed. Moreover, a criterion is proposed to evaluate the performance of models. Cost reduction in power system operation, as proposed, is more realistic than prevalent criteria, such as, root mean square error (RMSE) and absolute mean error (MAE). Two advanced space-time statistical models are introduced for short-term wind speed forecasting. One is a modified regime-switching, space-time wind speed fore- casting model, which allows the forecast regimes to vary according to the dominant wind direction and seasons. Thus, it avoids a subjective choice of regimes. The other one is a novel model that incorporates a new variable, geostrophic wind, which has strong influence on the surface wind, into one of the advanced space-time statistical forecasting models. This model is motivated by the lack of improvement in forecast accuracy when using air pressure and temperature directly. Using geostrophic wind in the model is not only critical, it also has a meaningful geophysical interpretation. The importance of model evaluation is emphasized in the dissertation as well. Rather than using RMSE or MAE, the performance of both wind forecasting models mentioned above are assessed by economic benefits with real wind farm data from Pacific Northwest of the U.S and West Texas. Wind forecasts are incorporated into power system economic dispatch models, and the power system operation cost is used as a loss measure for the performance of the forecasting models. From another perspective, the new criterion leads to cost-effective scheduling of system-wide wind generation with potential economic benefits arising from the system-wide generation of cost savings and ancillary services cost savings. As an illustration, the integrated forecasts and economic dispatch framework are applied to the Electric Reliability Council of Texas (ERCOT) equivalent 24- bus system. Compared with persistence and autoregressive models, the first model suggests that cost savings from integration of wind power could be on the scale of tens of millions of dollars. For the second model, numerical simulations suggest that the overall generation cost can be reduced by up to 6.6% using look-ahead dispatch coupled with spatio-temporal wind forecast as compared with dispatch with persistent wind forecast model.

Independent System Operators and Biomass Power  

DOE Green Energy (OSTI)

Since the Federal Energy Regulatory Commission issued its landmark open access transmission rule in 1996, the idea of creating and establishing independent system operators (ISOs) has gained momentum. ISOs may help combine individual utility transmission systems into more regional transmission networks, which ultimately will allow biomass companies to transmit power over longer distances while paying a single transmission rate. To the extent that ISOs are combined or operated with power exchanges, however, biomass companies will likely face even more competitive market pressures. Few operators have experience with ISOs and power exchanges, but preliminary results show that short-term electricity market prices are probably too low for most biomass companies to compete against. Without policy measures, biomass companies may have to pursue strategic opportunities with short-term, spot-market sales; direct bilateral sales to customers; alternative power exchanges; and perhaps a ''green'' pow er market and sales to ancillary service markets. In addition, prices will likely be more volatile in a restructured market so biomass generators should be selling during those times.

Modeling Power System Operation with Intermittent Resources  

Science Conference Proceedings (OSTI)

Electricity generating companies and power system operators face the need to minimize total fuel cost or maximize total profit over a given time period. These issues become optimization problems subject to a large number of constraints that must be satisfied simultaneously. The grid updates due to smart-grid technologies plus the penetration of intermittent re- sources in electrical grid introduce additional complexity to the optimization problem. The Renewable Integration Model (RIM) is a computer model of interconnected power system. It is intended to provide insight and advice on complex power systems management, as well as answers to integration of renewable energy questions. This paper describes RIM basic design concept, solution method, and the initial suite of modules that it supports.

Optimal monitoring and visualization of steady state power system operation  

E-Print Network (OSTI)

Power system operation requires accurate monitoring of electrical quantities and a reliable database of the power system. As the power system operation becomes more competitive, the secure operation becomes highly important and the role of state estimation becomes more critical. Recently, due to the development of new technology in high power electronics, new control and monitoring devices are becoming more popular in power systems. It is therefore necessary to investigate their models and integrate them into the existing state estimation applications. This dissertation is dedicated to exploiting the newly appeared controlling and monitoring devices, such as Flexible AC Transmission System (FACTS) devices and (Phasor Measurement Units) PMUs, and developing new algorithms to include them into power system analysis applications. Another goal is to develop a 3D visualization tool to help power system operators gain an in-depth image of the system operation state and to identify limit violations in a quick and intuitive manner. An algorithm of state estimation of a power system with embedded FACTS devices is developed first. This estimator can be used to estimate the system state quantities and Unified Power Flow Controller (UPFC) controller parameters. Furthermore, it can also to be used to determine the required controller setting to maintain a desired power flow through a given line. In the second part of this dissertation, two methods to determine the optimal locations of PMUs are derived. One is numerical and the other one is topological. The numerical method is more effective when there are very few existing measurements while the topology-based method is more applicable for a system, which has lots of measurements forming several observable islands. To guard against unexpected failures of PMUs, the numerical method is extended to account for single PMU loss. In the last part of this dissertation, a 3D graphic user interface for power system analysis is developed. It supports two basic application functions, power flow analysis and state estimation. Different visualization techniques are used to represent different kinds of system information.

Feasibility study for a transportation operations system cask maintenance facility  

SciTech Connect

The US Department of Energy (DOE), Office of Civilian Radioactive Waste Management (OCRWM) is responsible for the development of a waste management program for the disposition of spent nuclear fuel (SNF) and high-level waste (HLW). The program will include a transportation system for moving the nuclear waste from the sources to a geologic repository for permanent disposal. Specially designed casks will be used to safely transport the waste. The cask systems must be operated within limits imposed by DOE, the Nuclear Regulatory Commission (NRC), and the Department of Transportation (DOT). A dedicated facility for inspecting, testing, and maintaining the cask systems was recommended by the General Accounting Office (in 1979) as the best means of assuring their operational effectiveness and safety, as well as regulatory compliance. In November of 1987, OCRWM requested a feasibility study be made of a Cask Maintenance Facility (CMF) that would perform the required functions. 46 refs., 16 figs., 13 tabs.

SciTech Connect

A joint-service effort is under way to develop, evaluate, and field-test a Computerized Adaptive Testing version of the Armed Services Vocational Aptitude Battery (CAT-ASVAB). The CAT-ASVAB is being evaluated as a replacement for the Paper and Pencil ASVAB (P P-ASVAB), which is currently used for military personnel selection and classification. During the Score Equating Development (SED) phase of the evaluation, the CAT-ASVAB is being administered at a limited number of Military Entrance Processing Stations (MEPS). At these stations all examinees are given an operational P P-ASVAB; in addition, approximately one-third are given a nonoperational P P-ASVAB and two-thirds are given the CAT-ASVAB. Data are being transmitted from the MEPS to the Navy Personnel Research and Development Center (NPRDC) for analysis and storage in the Testing Systems Database. The Testing Systems Database (TSD) and its supporting programs reside on a minicomputer at the NPRDC's CAT-ASVAB Maintenance and Psychometric (CAMP) Facility in San Diego, California. The CAMP Facility supports the development, maintenance, and continuing improvement of the CAT-ASVAB testing program. The purpose of this Interface Operation Manual is to provide operating instructions for the TSD ''Interface,'' a system of menus and interactive screen displays that integrate the use of the TSD and its supporting programs. It is not the purpose of this manual to document in detail the general use of commercial or NPRDC-produced programs that are documented elsewhere. 34 figs.

Ufo: A Personal Global File System Based on User-Level Extensions to the Operating System  

E-Print Network (OSTI)

In this article we show how to extend a wide range of functionality of standard operating systems completely at the user level. Our approach works by intercepting selected system calls at the user level, using tracing facilities such as the /proc file system provided by many Unix operating systems. The behavior of some intercepted system calls is then modified to implement new functionality. This approach does not require any relinking or recompilation of existing applications. In fact, the extensions can even be dynamically "installed" into already running processes. The extensions work completely at the user level and install without system administrator assistance. Individual users can choose what extensions to run, in effect creating a personalized operating system view for themselves. We used this approach to implement a global file system, called Ufo, which allows users to treat remote files exactly as if they were local. Currently, Ufo supports file access through the FTP and HTTP protocols and allows new protocols to be plugged in. While several other projects have implemented global file system abstractions, they all require either changes to the operating system or modifications to standard libraries. The article gives a detailed performance analysis of our approach to extending the OS and establishes that Ufo introduces acceptable overhead for common applications even though intercepting individual system calls incurs a high cost.

Management of Power Demand through Operations of Building Systems  

E-Print Network (OSTI)

In hot summers, the demand for electrical power is dominated by the requirements of the air-conditioning and lighting systems. Such systems account for more than 80% of the peak electrical demand in Kuwait. A study was conducted to explore the potential for managing the peak electrical demand through improved operation strategies for building systems. Two buildings with partial occupancy patterns and typical peak loads of 1 and 2.2 MW were investigated. Changes to the operation of building systems included utilizing the thermal mass to reduce cooling production and distribution during the last hour of occupancy, time-of-day control of chillers and auxiliaries, and de-lamping. The implemented operational changes led to significant reductions in building loads during the hours of national peak demand. The achieved savings reached 31% during the critical hour, and up to 47% afterwards. Daily energy savings of 13% represented an added benefit. Additional operational changes could lead to further savings in peak power when implemented.

. OPUS is the platform on which the telemetry pipeline at the Hubble Space Telescope Science Institute is running currently. OPUS was developed both to repair the mistakes of the past, and to build a system which could meet the challenges of the future. The production pipeline inherited at the Space Telescope Science Institute was designed a decade earlier, and made assumptions about the environment which were unsustainable. While OPUS was developed in an environment that required a great deal of attention to throughput, speed, e#ciency, flexibility, robustness and extensibility, it is not just a "big science" machine. The OPUS platform, our baseline product, is a small compact system designed to solve a specific problem in a robust way. The OPUS platform handles communication with the OPUS blackboard; individual processes within this pipeline need have no knowledge of OPUS, of the blackboard, or of the pipeline itself.

REAL TIME SYSTEM OPERATIONS 2006-2007

The Real Time System Operations (RTSO) 2006-2007 project focused on two parallel technical tasks: (1) Real-Time Applications of Phasors for Monitoring, Alarming and Control; and (2) Real-Time Voltage Security Assessment (RTVSA) Prototype Tool. The overall goal of the phasor applications project was to accelerate adoption and foster greater use of new, more accurate, time-synchronized phasor measurements by conducting research and prototyping applications on California ISO's phasor platform - Real-Time Dynamics Monitoring System (RTDMS) -- that provide previously unavailable information on the dynamic stability of the grid. Feasibility assessment studies were conducted on potential application of this technology for small-signal stability monitoring, validating/improving existing stability nomograms, conducting frequency response analysis, and obtaining real-time sensitivity information on key metrics to assess grid stress. Based on study findings, prototype applications for real-time visualization and alarming, small-signal stability monitoring, measurement based sensitivity analysis and frequency response assessment were developed, factory- and field-tested at the California ISO and at BPA. The goal of the RTVSA project was to provide California ISO with a prototype voltage security assessment tool that runs in real time within California ISO?s new reliability and congestion management system. CERTS conducted a technical assessment of appropriate algorithms, developed a prototype incorporating state-of-art algorithms (such as the continuation power flow, direct method, boundary orbiting method, and hyperplanes) into a framework most suitable for an operations environment. Based on study findings, a functional specification was prepared, which the California ISO has since used to procure a production-quality tool that is now a part of a suite of advanced computational tools that is used by California ISO for reliability and congestion management.

The Conditions Database of the LHCb experiment (CondDB) provides versioned, time dependent geometry and conditions data for all LHCb data processing applications (simulation, high level trigger, reconstruction, analysis) in a heterogeneous computing environment ranging from user laptops to the HLT farm and the Grid. These different use cases impose front-end support for multiple database technologies (Oracle and SQLite are used). Sophisticated distribution tools are required to ensure timely and robust delivery of updates to all environments. The content of the database has to be managed to ensure that updates are internally consistent and externally compatible with multiple versions of the physics application software. In this paper we describe three systems that we have developed to address these issues: - an extension to the automatic content validation done by the “Oracle Streams” replication technology, to trap cases when the replication was unsuccessful; - an automated distribution process for the S...

An augmented reality system for military operations in urban terrain  

E-Print Network (OSTI)

Many future military operations are expected to occur in urban environments. These complex, 3D battlefields introduce many challenges to the dismounted warfighter. Better situational awareness is required for effective operation in urban environments. However, delivering this information to the dismounted warfighter is extremely difficult. For example, maps draw a user's attention away from the environment and cannot directly represent the three-dimensional nature of the terrain. To overcome these difficulties, we are developing the Battlefield Augmented Reality System (BARS). The system consists of a wearable computer, a wireless network system, and a tracked see-through head-mounted display (HMD). The computer generates graphics that, from the user's perspective, appear to be aligned with the actual environment. For example, a building could be augmented to show its name, a plan of its interior, icons to represent reported sniper locations, and the names of adjacent streets. This paper surveys the current state of development of BARS and describes ongoing research efforts. We describe four major research areas. The first is the development of an effective, efficient user interface for displaying data and processing user inputs. The second is the capability for collaboration between multiple BARS users and other systems. Third, we describe the current hardware for both a mobile and indoor prototype system. Finally, we

Dynamic model of power system operation incorporating load control  

SciTech Connect

Load management has been proposed as a means whereby an electric utility can reduce its requirements for additional generation, transmission, and distribution investments, shift fuel dependency from limited to more abundant energy resources, and improve the efficiency of the electric energy system. There exist, however, serious technological and economic questions which must be answered to define the cost trade-offs between initiating a load management strategy or adding additional capacity to meet the load. One aspect of this complex problem is to determine how the load profile might be modified by the load management option being considered. Towards this end, a model has been developed to determine how a power system with an active load control system should be operated to make the best use of its available resources. The model is capable of handling all types of conventional generating sources including thermal, hydro, and pumped storage units, and most appliances being considered for direct control including those with inherent or designed storage characteristics. The model uses a dynamic programming technique to determine the optimal operating strategy for a given set of conditions. The use of the model is demonstrated. Case study results indicate that the production cost savings that can be achieved through the use of direct load control are highly dependent on utility characteristics, load characteristics, storage capacity, and penetration. The load characteristics that produce the greatest savings are: large storage capacity; high coincidence with the system peak; large connected load per point; and moderately high diversity fraction.

Power-Aware Operating Systems for Interactive Systems  

E-Print Network (OSTI)

Many portable systems deploy operating systems (OS) to support versatile functionality and to manage resources, including power. This paper presents a new approach for using OS to reduce the power consumption of IO devices in interactive systems. Low-power OS observes the relationship between hardware devices and processes. The OS kernel estimates the utilization of a device from each process. If a device is not used by any running process, the OS puts it into a low-power state. This paper also explains how scheduling can facilitate power management. When processes are properly scheduled, power reduction can be achieved without degrading performance. We implemented a prototype on Linux to control two devices; experimental results showed nearly 70% power saving on a network card and a hard disk drive.

Improved accounting of emissions from utility energy storage system operation  

Science Conference Proceedings (OSTI)

Several proposed utility-scale energy storage systems in the U.S. will use the spare output capacity of existing electric power systems to create the equivalent of new load-following plants that can rapidly respond to fluctuations in electricity demand and increase the flexibility of baseload generators. New energy storage systems using additional generation from existing plants can directly compete with new traditional sources of load-following and peaking electricity, yet this application of energy storage is not required to meet many of the Clean Air Act standards required of new electricity generators (e.g., coal- or gas-fired power plants). This study evaluates the total emissions that will likely result from the operation of a new energy storage facility when coupled with an average existing U.S. coal-fired power plant and estimates that the emission rates of SO{sub 2} and NOx will be considerably higher than the rate of a new plant meeting Clean Air Act standards, even accounting for the efficiency benefits of energy storage. This study suggests that improved emissions 'accounting' might be necessary to provide accurate environmental comparisons between energy storage and more traditional sources of electricity generation. 35 refs., 5 figs., 2 tabs.

Motor-operated valve reliability programs: Lessons learned to meet new NRC (Nuclear Regulatory Commission) requirements  

Science Conference Proceedings (OSTI)

In recent years, reliability problems have surfaced with power plant motor-operated valves (MOVs) that (a) fail to perform as designed, and/or (b) require excessive maintenance to perform their intended function. As a result, the US Nuclear Regulatory Commission (NRC) mandated certain testing and reporting requirements in inspection and enforcement bulletin 85-03 (85-03). The NRC's generic letter 89-10 (89-10) significantly expands these requirements, to include all safety-related and position-changeable MOVs. The MOV program experience at the Sacramento Municipal Utility District (SMUD) Rancho Seco plant is particularly valuable since the NRC, to a large extent, utilized this program as the prototype for 89-10's requirements. The MOV inspection, overhaul, and testing began in September 1986, with completion scheduled for December 1986. The paper discusses problems encountered, recovery plant, results of recovery planning, and lessons learned. Experience at Rancho Seco has shown that comprehensive valve programs incorporating appropriate design practices, preventive maintenance practices, and operational constraints can improve plant availability.

The Impact of Solar Photovoltaic Generation on Balancing Requirements in the Southern Nevada System  

Science Conference Proceedings (OSTI)

Abstract—The impact of integrating large-scale solar photovoltaic (PV) generation on the balancing requirements in terms of regulation and load-following requirements in the southern Nevada balancing area is evaluated. The “swinging door” algorithm and the “probability box” method developed by Pacific Northwest National Laboratory (PNNL) were used to quantify the impact of large PV generation on the balancing requirements of the system operations. The system’s actual scheduling, real-time dispatch and regulation processes were simulated. Different levels of distributed generation were also considered in the study. The impact of hourly solar PV generation forecast errors on regulation and load-following requirements was assessed. The sensitivity of balancing requirements with respect to real-time forecast errors of large PV generation was analyzed. Index Terms—Ancillary services, balancing requirements, load following, regulation, renewables integration, swinging door

Energy Efficient Operation of Ammonia Refrigeration Systems  

SciTech Connect

Ammonia refrigeration systems typically offer many energy efficiency opportunities because of their size and complexity. This paper develops a model for simulating single-stage ammonia refrigeration systems, describes common energy saving opportunities, and uses the model to quantify those opportunities. The simulation model uses data that are typically available during site visits to ammonia refrigeration plants and can be calibrated to actual consumption and performance data if available. Annual electricity consumption for a base-case ammonia refrigeration system is simulated. The model is then used to quantify energy savings for six specific energy efficiency opportunities; reduce refrigeration load, increase suction pressure, employ dual suction, decrease minimum head pressure set-point, increase evaporative condenser capacity, and reclaim heat. Methods and considerations for achieving each saving opportunity are discussed. The model captures synergistic effects that result when more than one component or parameter is changed. This methodology represents an effective method to model and quantify common energy saving opportunities in ammonia refrigeration systems. The results indicate the range of savings that might be expected from common energy efficiency opportunities.

Optimizing the Day to Day Operation of Utility Systems  

E-Print Network (OSTI)

At the 2002 IETC, Linnhoff March presented an overview of spreadsheet-based software packages to rigorously model site utility systems. Such models allow the user to plan future scenarios that might impact upon the system operation (energy saving projects, production changes, new equipment, future energy tariffs, etc). Indeed, since last year, the DOE has made utility system template models freely available to industrial users as reported elsewhere at the 2003 IETC. Until last year, most industrial applications of this utility system software were set up for planning purposes, largely off-line. More recently, these applications have become more sophisticated and can operate on-line in real time. They include complex optimization routines to ensure that the utility system is always being operated in the best possible way under any prevailing conditions of production, energy tariffs and other variables. These optimizer models typically reduce day-to-day utility system operating costs by between 2 and 5%.

Operational Flexibility Guidelines for Gas Turbine Low NOx Combustion Systems

Gas turbine low-NOx combustion systems can differ in hardware from manufacturer to manufacturer, but the principle is the same. Low-NOx combustors reduce peak flame temperatures by mixing fuel and air before combustion and by keeping the fuel-to-air ratio as low (lean) as possible, while still maintaining combustion stability over the broadest possible operating range. Low-NOx combustion systems are inherently more complex than diffusion combustion systems, a fact that impacts operational flexibility, re...

Ventilation Systems Operating Experience Review for Fusion Applications  

SciTech Connect

This report is a collection and review of system operation and failure experiences for air ventilation systems in nuclear facilities. These experiences are applicable for magnetic and inertial fusion facilities since air ventilation systems are support systems that can be considered generic to nuclear facilities. The report contains descriptions of ventilation system components, operating experiences with these systems, component failure rates, and component repair times. Since ventilation systems have a role in mitigating accident releases in nuclear facilities, these data are useful in safety analysis and risk assessment of public safety. An effort has also been given to identifying any safety issues with personnel operating or maintaining ventilation systems. Finally, the recommended failure data were compared to an independent data set to determine the accuracy of individual values. This comparison is useful for the International Energy Agency task on fusion component failure rate data collection.

NEUTRONIC REACTOR OPERATIONAL METHOD AND CORE SYSTEM  

DOE Patents (OSTI)

Homogeneous neutronic reactor systems are described wherein an aqueous fuel solution is continuously circulated through a spherical core tank. The pumped fuel solution-is injected tangentially into the hollow spherical interior, thereby maintaining vigorous rotation of the solution within the tank in the form of a vortex; gaseous radiolytic decomposition products concentrate within the axial vortex cavity. The evolved gas is continuously discharged through a gas- outlet port registering with an extremity of the vortex cavity. and the solution stream is discharged through an annular liquid outlet port concentrically encircling the gas outlet by virtue of which the vortex and its cavity are maintained precisely axially aligned with the gas outlet. A primary heat exchanger extracts useful heat from the hot effluent fuel solution before its recirculation into the core tank. Hollow cylinders and other alternative core- tank configurations defining geometric volumes of revolution about a principal axis are also covered. AEC's Homogeneous Reactor Experiment No. 1 is a preferred embodiment.

Engineering Task Plan for Standard Hydrogen Monitoring System Operation  

DOE Green Energy (OSTI)

Tanks that are known or suspected to retain and occasionally release flammable gases are equipped with Standard Hydrogen Monitoring System (SHMS) cabinets. These cabinets contain Whittaker{trademark} electrochemical cells and may also have a gas chromatograph (GC) and/or a Bruel and Kjaer infrared photo-acoustic multi-gas monitor (B&K). The GC and B&K will be referred to collectively as ''analytical instruments'' in this document. Using these instruments, a tank can be monitored for hydrogen, helium, ammonia, methane, and nitrous oxide. Air from the tank vent header (for actively ventilated tanks) or dome space (for passively ventilated tanks) is drawn continuously through the monitoring instruments via a sample pump. This monitoring is performed to track the gas release behavior of selected waste storage tanks and to help identify any potentially serious gas release behavior. Vapor grab samples may be obtained from the SHMS as well and analyzed with a mass spectrometer to obtain concentration data about hydrogen and other gases. This document describes the requirements for the operation, maintenance, calibration, and data collection for the Standard Hydrogen Monitoring System. Additionally, this document defines who is responsible for the various tasks.

Software requirements definition Shipping Cask Analysis System (SCANS)  

SciTech Connect

The US Nuclear Regulatory Commission (NRC) staff reviews the technical adequacy of applications for certification of designs of shipping casks for spent nuclear fuel. In order to confirm an acceptable design, the NRC staff may perform independent calculations. The current NRC procedure for confirming cask design analyses is laborious and tedious. Most of the work is currently done by hand or through the use of a remote computer network. The time required to certify a cask can be long. The review process may vary somewhat with the engineer doing the reviewing. Similarly, the documentation on the results of the review can also vary with the reviewer. To increase the efficiency of this certification process, LLNL was requested to design and write an integrated set of user-oriented, interactive computer programs for a personal microcomputer. The system is known as the NRC Shipping Cask Analysis System (SCANS). The computer codes and the software system supporting these codes are being developed and maintained for the NRC by LLNL. The objective of this system is generally to lessen the time and effort needed to review an application. Additionally, an objective of the system is to assure standardized methods and documentation of the confirmatory analyses used in the review of these cask designs. A software system should be designed based on NRC-defined requirements contained in a requirements document. The requirements document is a statement of a project's wants and needs as the users and implementers jointly understand them. The requirements document states the desired end products (i.e. WHAT's) of the project, not HOW the project provides them. This document describes the wants and needs for the SCANS system. 1 fig., 3 tabs.

Identifying Challenging Operating Hours for Solar Intergration in the NV Energy System  

Science Conference Proceedings (OSTI)

Abstract-- In this paper, the ability of the Nevada (NV) Energy generation fleet to meet its system balancing requirements under different solar energy penetration scenarios is studied. System balancing requirements include capacity, ramp rate, and ramp duration requirements for load following and regulation. If, during some operating hours, system capability is insufficient to meet these requirements, there is certain probability that the balancing authority’s control and reliability performance can be compromised. These operating hours are considered as “challenging” hours. Five different solar energy integration scenarios have been studied. Simulations have shown that the NV Energy system will be potentially able to accommodate up to 942 MW of solar photovoltaic (PV) generation. However, the existing generation scheduling procedure should be adjusted to make it happen. Fast-responsive peaker units need to be used more frequently to meet the increasing ramping requirements. Thus, the NV Energy system operational cost can increase. Index Terms—Solar Generation, Renewables Integration, Balancing Process, Load Following, Regulation.

Operational test report -- Project W-320 cathodic protection systems  

Science Conference Proceedings (OSTI)

Washington Administrative Code (WAC) 173-303-640 specifies that corrosion protection must be designed into tank systems that treat or store dangerous wastes. Project W-320, Waste Retrieval Sluicing System (WRSS), utilizes underground encased waste transfer piping between tanks 241-C-106 and 241-AY-102. Corrosion protection is afforded to the encasements of the WRSS waste transfer piping through the application of earthen ionic currents onto the surface of the piping encasements. Cathodic protection is used in conjunction with the protective coatings that are applied upon the WRSS encasement piping. WRSS installed two new two rectifier systems (46 and 47) and modified one rectifier system (31). WAC 173-303-640 specifies that the proper operation of cathodic protection systems must be confirmed within six months after initial installation. The WRSS cathodic protection systems were energized to begin continuous operation on 5/5/98. Sixteen days after the initial steady-state start-up of the WRSS rectifier systems, the operational testing was accomplished with procedure OTP-320-006 Rev/Mod A-0. This operational test report documents the OTP-320-006 results and documents the results of configuration testing of integrated piping and rectifier systems associated with the W-320 cathodic protection systems.

Integrated Chiller System Reduce Building Operation and Maintenance Costs in Cold Climates  

E-Print Network (OSTI)

Although water-cooled chillers are more energy efficient than air-cooled chillers, a majority of chilled water systems use air-cooled chillers. In cold weather climates, air-cooled chillers are capable of functioning in low ambient temperatures with few operational concerns, where as water-cooled chiller systems must be equipped to prevent cooling tower freezing. The integrated chiller system attempts to take advantage of each chiller's strengths and eliminate any cold weather operational concerns. An integrated chiller system includes a cooling tower and air-cooled condenser. During the summer, both the cooling tower and air condenser can be operated. In cold weather, the cooling tower is drained and the air condenser is used to dissipate the heat of the cooling system. The integrated chiller system eliminates the water storage tank and frequent charging and discharging of the cooling tower system. It reduces the size of the mechanical room and simplifies the operation of the system. The integrated chiller system is most suitable in climates where the mechanical cooling is required on a short-term basis during cold weather periods. This paper presents the system configuration, system design, optimal control, and energy impact. An example is used to demonstrate the design concepts of the integrated chiller systems.

Hourly steam load demands can swing by as much as 500% in some plants, making responsive water treatment of the boiler system difficult. This challenging production environment is made even more so by volatile economic forces in today's world. New technologies have been developed that help steam operations staff achieve more consistent, proactive boiler feedwater treatment by detecting system variability, determining the correct chemical or operational action, and delivering measurable environmental return on investment (ROI). These new technologies will be described and several case histories presented. The steam boiler system is a critical component of most manufacturing processes.

NGSI: FUNCTION REQUIREMENTS FOR A CYLINDER TRACKING SYSTEM  

SciTech Connect

While nuclear suppliers currently track uranium hexafluoride (UF{sub 6}) cylinders in various ways, for their own purposes, industry practices vary significantly. The NNSA Office of Nonproliferation and International Security's Next Generation Safeguards Initiative (NGSI) has begun a 5-year program to investigate the concept of a global monitoring scheme that uniquely identifies and tracks UF{sub 6} cylinders. As part of this effort, NGSI's multi-laboratory team has documented the 'life of a UF{sub 6} cylinder' and reviewed IAEA practices related to UF{sub 6} cylinders. Based on this foundation, this paper examines the functional requirements of a system that would uniquely identify and track UF{sub 6} cylinders. There are many considerations for establishing a potential tracking system. Some of these factors include the environmental conditions a cylinder may be expected to be exposed to, where cylinders may be particularly vulnerable to diversion, how such a system may be integrated into the existing flow of commerce, how proprietary data generated in the process may be protected, what a system may require in terms of the existing standard for UF{sub 6} cylinder manufacture or modifications to it and what the limiting technology factors may be. It is desirable that a tracking system should provide benefit to industry while imposing as few additional constraints as possible and still meeting IAEA safeguards objectives. This paper includes recommendations for this system and the analysis that generated them.

Integration of Uncertainty Information into Power System Operations  

Science Conference Proceedings (OSTI)

Contemporary power systems face uncertainties coming from multiple sources, including forecast errors of load, wind and solar generation, uninstructed deviation and forced outage of traditional generators, loss of transmission lines, and others. With increasing amounts of wind and solar generation being integrated into the system, these uncertainties have been growing significantly. It is critical important to build knowledge of major sources of uncertainty, learn how to simulate them, and then incorporate this information into the decision-making processes and power system operations, for better reliability and efficiency. This paper gives a comprehensive view on the sources of uncertainty in power systems, important characteristics, available models, and ways of their integration into system operations. It is primarily based on previous works conducted at the Pacific Northwest National Laboratory (PNNL).

Load Response Fundamentally Matches Power System Reliability Requirements  

Science Conference Proceedings (OSTI)

Responsive load is the most underutilized reliability resource available to the power system. Loads are frequently barred from providing the highest value and most critical reliability services; regulation and spinning reserve. Advances in communications and control technology now make it possible for some loads to provide both of these services. The limited storage incorporated in some loads better matches their response capabilities to the fast reliability-service markets than to the hourly energy markets. Responsive loads are frequently significantly faster and more accurate than generators, increasing power system reliability. Incorporating fast load response into microgrids further extends the reliability response capabilities that can be offered to the interconnected power system. The paper discusses the desired reliability responses, why this matches some loads' capabilities, what the advantages are for the power system, implications for communications and monitoring requirements, and how this resource can be exploited.

Power system requirements and selection for the space exploration initiative  

Science Conference Proceedings (OSTI)

The Space Exploration Initiative (SEI) seeks to reestablish a US program of manned and unmanned space exploration. The President has called for a program which includes a space station element, a manned habitation of the moon, and a human exploration of Mars. The NASA Synthesis Group has developed four significantly different architectures for the SEI program. One key element of a space exploration effort is the power required to support the missions. The Power Speciality Team of the Synthesis Group was tasked with assessing and evaluating the power requirements and candidate power technologies for such missions. Inputs to the effort came from existing NASA studies as well as other governments agency inputs such as those from DOD and DOE. In addition, there were industry and university briefings and results of solicitations from the AIAA and the general public as part of the NASA outreach effort. Because of the variety of power needs in the SEI program, there will be a need for multiple power system technologies including solar, nuclear and electrochemical. Due to the high rocket masses required to propel payloads to the moon and beyond to Mars, there is great emphasis placed on the need for high power density and high energy density systems. Power system technology development work is needed results will determine the ultimate technology selections. 23 refs., 10 figs.

SYSTEM PLANNING WITH THE HANFORD WASTE OPERATIONS SIMULATOR  

SciTech Connect

At the U. S. Department of Energy's Hanford Site in southeastern Washington State, 216 million liters (57 million gallons) of nuclear waste is currently stored in aging underground tanks, threatening the Columbia River. The River Protection Project (RPP), a fully integrated system of waste storage, retrieval, treatment, and disposal facilities, is in varying stages of design, construction, operation, and future planning. These facilities face many overlapping technical, regulatory, and financial hurdles to achieve site cleanup and closure. Program execution is ongoing, but completion is currently expected to take approximately 40 more years. Strategic planning for the treatment of Hanford tank waste is by nature a multi-faceted, complex and iterative process. To help manage the planning, a report referred to as the RPP System Plan is prepared to provide a basis for aligning the program scope with the cost and schedule, from upper-tier contracts to individual facility operating plans. The Hanford Tank Waste Operations Simulator (HTWOS), a dynamic flowsheet simulation and mass balance computer model, is used to simulate the current planned RPP mission, evaluate the impacts of changes to the mission, and assist in planning near-term facility operations. Development of additional modeling tools, including an operations research model and a cost model, will further improve long-term planning confidence. The most recent RPP System Plan, Revision 4, was published in September 2009.

Improving Building Control and System Operation Through the Continuous Commissioning® Process: A Case Study  

E-Print Network (OSTI)

Utilization of the Continuous Commissioning® process is presented in the case of the Consolidated Mission Support Center office building at Travis Air Force Base in Travis, California. The CC® process was applied to the building in early 2003. The examination of the heating, ventilating, and airconditioning (HVAC) and control systems revealed several areas where considerable improvement could be made, including air handling unit (AHU) operational parameters, terminal box and water loop operation, and Energy Management and Control System (EMCS) functionality. It also aided in the identification of mechanical systems needing repair. The optimization of the HVAC systems and advanced utilization of the EMCS reduced the combined heating and cooling energy consumption by 26% without capital intensive upgrades. Cooling energy decreased by 10%, heating energy was cut by over 40%, and fan power decreased by 28%. A hidden benefit to the implementation of the CC® process is the reduction in the human capital required to operate the building. Prior to commissioning, significant time was spent changing system operating setpoints in an attempt to save energy. These efforts are no longer required.

HEMP emergency planning and operating procedures for electric power systems  

SciTech Connect

Investigations of the impact of high-altitude electromagnetic pulse (HEMP) on electric power systems and electrical equipment have revealed that HEMP creates both misoperation and failures. These events result from both the early time E[sub 1] (steep-front pulse) component and the late time E[sub 3] (geomagnetic perturbations) component of HEMP. In this report a HEMP event is viewed in terms of its marginal impact over classical power system disturbances by considering the unique properties and consequences of HEMP. This report focuses on system-wide electrical component failures and their potential consequences from HEMP. In particular, the effectiveness of planning and operating procedures for electric systems is evaluated while under the influence of HEMP. This assessment relies on published data and characterizes utilities using the North American Electric Reliability Council's regions and guidelines to model electric power system planning and operations. Key issues addressed by the report include how electric power systems are affected by HEMP and what actions electric utilities can initiate to reduce the consequences of HEMP. The report also reviews the salient features of earlier HEMP studies and projects, examines technology trends in the electric power industry which are affected by HEMP, characterizes the vulnerability of power systems to HEMP, and explores the capability of electric systems to recover from a HEMP event.

Performances of Induction System for Nanosecond Mode Operation  

SciTech Connect

An induction system comprises an array of single turn pulse transformers. Ferromagnetic cores of transformers are toroids that are stacked along the longitudinal core axis. Another name for this array is a fraction transformer or an adder. The primary and secondary windings of such a design have one turn. The step up mode is based on the number of primary pulse sources. The secondary windings are connected in series. Performances of such a system for the nanosecond range mode operation are different in comparison to the performances of traditional multi-turn pulse transformers, which are working on a 100+ nanosecond mode operation. In this paper, the author discusses which aspects are necessary to take into account for the high power nanosecond fractional transformer designs. The engineering method of the nanosecond induction system design is presented.

Impact of dispersed solar and wind systems on electric distribution planning and operation  

DOE Green Energy (OSTI)

Small-scale dispersed solar photovoltaic and wind generation (DSW) will affect the generation, transmission, and distribution systems of an electric utility. This study examines the technical and economic impacts of dispersing DSW devices within the distribution system. Dispersed intermittent generation is included. Effects of DSW devices on capital investments, reliability, operating and maintenance costs, protection requirements, and communication and control requirements are examined. A DSW operation model is developed to help determine the dependable capacity of fluctuating solar photovoltaic and wind generation as part of the distribution planning process. Specific case studies using distribution system data and renewable resource data for Southern California Edison Company and Consumers Power Company are analyzed to gain insights into the effects of interconnecting DSW devices. The DSW devices were found to offer some distribution investment savings, depending on their availability during peak loads. For a summer-peaking utility, for example, dispersing photovoltaic systems is more likely to defer distribution capital investments than dispersing wind systems. Dispersing storage devices to increase DSW's dependable capacity for distribution systems needs is not economically attractive. Substation placement of DSW and storage devices is found to be more cost effective than feeder or customer placement. Examination of the effects of DSW on distribution system operation showed that small customer-owned DSW devices are not likely to disrupt present time-current distribution protection coordination. Present maintenance work procedures, are adequate to ensure workmen's safety. Regulating voltages within appropriate limits will become more complex with intermittent generation along the distribution feeders.

SciTech Connect

The Emergency, Safety, & Quality (ESQ) Services organization of Westinghouse Hanford Company (WHC) is experiencing changes related to new programs. The programs include Corrective Actions Management Systems, Self-Assessment, Trend Analysis, and Lessons Learned analysis. The programs are pushing up organizational costs while funding and manpower levels are projected to be dropping. A large cost involved in implementing the new programs is the cost for people to locate unstructured information required to make decisions or write documentation. But, most resources for retrieving information are found in structured database systems. This means that unstructured information that must be located has to be found by one of these methods: (1) searching manually through documents, (2) searching individual documents one at a time with word processing programs, (3) searching through text fields with query systems primarily designed for structured database information, or (4) develop a text search and retrieval system designed for unstructured information. One example of this is using Occurrence Reporting Processing System (ORPS) and Quality, Environmental, and Safety Tracking (QUEST) documents. An explanation of this is in the following textual box.

Applications of Optimal Building Energy System Selection and Operation  

DOE Green Energy (OSTI)

Berkeley Lab has been developing the Distributed Energy Resources Customer Adoption Model (DER-CAM) for several years. Given load curves for energy services requirements in a building microgrid (u grid), fuel costs and other economic inputs, and a menu of available technologies, DER-CAM finds the optimum equipment fleet and its optimum operating schedule using a mixed integer linear programming approach. This capability is being applied using a software as a service (SaaS) model. Optimisation problems are set up on a Berkeley Lab server and clients can execute their jobs as needed, typically daily. The evolution of this approach is demonstrated by description of three ongoing projects. The first is a public access web site focused on solar photovoltaic generation and battery viability at large commercial and industrial customer sites. The second is a building CO2 emissions reduction operations problem for a University of California, Davis student dining hall for which potential investments are also considered. And the third, is both a battery selection problem and a rolling operating schedule problem for a large County Jail. Together these examples show that optimization of building u grid design and operation can be effectively achieved using SaaS.

OPERATIONAL EXPERIENCE OF THE UPGRADED CRYOGENIC SYSTEMS AT THE NSCL  

Science Conference Proceedings (OSTI)

The National Superconducting Cyclotron Laboratory (NSCL) is a NSF-supported facility, with additional support from Michigan State University (MSU) for conducting research in nuclear and accelerator science. The facility consists of two superconducting cyclotrons and over fifty individual cryostats, each containing several superconducting magnets that are used in the beam transport system. Beginning in 1999 a major facility upgrade was started. New, larger magnets were added, increasing the total 4.5 K loads, necessitating an increase of the cryogenic capacity. A helium plant (nominal 1750-Watt at 4.5 K) was acquired from the United States Bureau of Mines where it had been operating as a pure liquefier since the early 1980's. It was refurbished for the NSCL with extensive support from the cryogenics group at Thomas Jefferson National Laboratory. The new cryogenic system came online early in 2001. The cold-mass is relatively high in relation to the installed capacity, presenting challenges during cool downs. Reliability over the last five years has been greater than 99%. An overview of the last seven years of operations of our cryogenic systems is presented that includes normal operations, testing of new equipment, noteworthy breakdowns, routine maintenance, and system reliability.

Method and apparatus to predict the remaining service life of an operating system  

DOE Patents (OSTI)

A method and computer-based apparatus for monitoring the degradation of, predicting the remaining service life of, and/or planning maintenance for, an operating system are disclosed. Diagnostic information on degradation of the operating system is obtained through measurement of one or more performance characteristics by one or more sensors onboard and/or proximate the operating system. Though not required, it is preferred that the sensor data are validated to improve the accuracy and reliability of the service life predictions. The condition or degree of degradation of the operating system is presented to a user by way of one or more calculated, numeric degradation figures of merit that are trended against one or more independent variables using one or more mathematical techniques. Furthermore, more than one trendline and uncertainty interval may be generated for a given degradation figure of merit/independent variable data set. The trendline(s) and uncertainty interval(s) are subsequently compared to one or more degradation figure of merit thresholds to predict the remaining service life of the operating system. The present invention enables multiple mathematical approaches in determining which trendline(s) to use to provide the best estimate of the remaining service life.

Use of Frequency Response Metrics to Assess the Planning and Operating Requirements for Reliable Integration of Variable Renewable Generation  

SciTech Connect

An interconnected electric power system is a complex system that must be operated within a safe frequency range in order to reliably maintain the instantaneous balance between generation and load. This is accomplished by ensuring that adequate resources are available to respond to expected and unexpected imbalances and restoring frequency to its scheduled value in order to ensure uninterrupted electric service to customers. Electrical systems must be flexible enough to reliably operate under a variety of"change" scenarios. System planners and operators must understand how other parts of the system change in response to the initial change, and need tools to manage such changes to ensure reliable operation within the scheduled frequency range. This report presents a systematic approach to identifying metrics that are useful for operating and planning a reliable system with increased amounts of variable renewable generation which builds on existing industry practices for frequency control after unexpected loss of a large amount of generation. The report introduces a set of metrics or tools for measuring the adequacy of frequency response within an interconnection. Based on the concept of the frequency nadir, these metrics take advantage of new information gathering and processing capabilities that system operators are developing for wide-area situational awareness. Primary frequency response is the leading metric that will be used by this report to assess the adequacy of primary frequency control reserves necessary to ensure reliable operation. It measures what is needed to arrest frequency decline (i.e., to establish frequency nadir) at a frequency higher than the highest set point for under-frequency load shedding within an interconnection. These metrics can be used to guide the reliable operation of an interconnection under changing circumstances.

DOE Green Energy (OSTI)

This document reports on a computer code, SOLSTOR W/D, that determines --- for a site's wind energy resources, load requirements, and economic constraints --- the components and sizes for a wind/diesel system that result in the lowest cost of energy. Wind diesel systems are defined here as electricity generation stations in the 50-kW to 1-MW range that (1) are not connected to another electricity network, (2) use wind energy as the first source of supply to meet demand, and (3) contain sufficient energy storage and/or backup diesel electric generators to compensate for lapses in wind energy. The computer code also determines, for the same input load, the requirements and economics that are the best number and size for an isolated diesel(s) system so that comparisons for wind/diesel systems and diesel-only systems can be made. SOLSTOR W/D provides a systematic method to show whether wind-diesel systems can be an attractive means of saving fossil fuel without significantly affecting electricity quality or production cost. 12 refs., 66 figs., 5 tabs.

Analyses of Wind Energy Impact on WFEC System Operations  

SciTech Connect

Western Farmers Electric Cooperative (WFEC) is a generation and transmission Cooperative in Oklahoma. At the end of 2003 it added 74 megawatts (MW) of wind energy to its energy portfolio by purchasing the output of the Blue Canyon Wind Power Project located north of Lawton, Oklahoma. The wind energy has the potential to provide about 6% of WFEC's peak summer energy demand. During periods of high winds and low loads, wind energy may represent 14% of the control area load. Conversely during periods of calm wind, wind energy cannot be counted upon to provide any energy to WFEC's system. This report analyzes system and wind energy data recorded by the WFEC control area energy management system (EMS) and evaluates the effects of wind energy on system operations.

Fuzzy logic based operated device identification in power distribution systems  

E-Print Network (OSTI)

Fault location in distribution systems is a challenging task because of the lack of homogeneity in the system and due to uncertainity in the data used for estimating the faulted sections. Fuzzy logic has widely been applied for handling uncertainities in the input data and its processing. Fuzzy logic has also been used to model human expertise and decision making capabilites and to determine the possibility of a fault on a particular section. This thesis presents the design and implementation of an operated device identification algorithm to be used as one of four modules in an automated modular scheme for fault section estimation on radial distribution systems. This algorithm will be executed in tandem with the other fault location modules that form the second stage of a three stage scheme. The operated device identification algorithm can assign section fault possibilities representing the possibility of involvement of each section of a distribution feeder in an event. The operated device algorithm uses the recorded current waveform of an abnormal event, the time-current characteristics and settings of various protective devices on a feeder, and feeder topology information as inputs. The algorithm then assigns a fault possibility value to each section of a feeder using fuzzy rules and fuzzy membership functions to compare a fault event with protective device settings and characteristics. The section fault possibility values can be superimposed on the feeder map by color coding the sections of a feeder according to their fault possibility values. This helps in easy visualization of possibly faulted sections. A detailed illustration of the results obtained from running the algorithm is presented in this thesis. They prove the effectiveness of the algorithm in locating faults in a distribution feeder. The operated device identification module was tested using real data measured at feeder substations. The results obtained by the algorithm were verified with feedback given by the utilities that owned the feeders. The results obtained from the tests were encouraging.

Operational characteristics of a parallel jet MILD combustion burner system  

SciTech Connect

This study describes the performance and stability characteristics of a parallel jet MILD (Moderate or Intense Low-oxygen Dilution) combustion burner system in a laboratory-scale furnace, in which the reactants and exhaust ports are all mounted on the same wall. Thermal field measurements are presented for cases with and without combustion air preheat, in addition to global temperature and emission measurements for a range of equivalence ratio, heat extraction, air preheat and fuel dilution levels. The present furnace/burner configuration proved to operate without the need for external air preheating, and achieved a high degree of temperature uniformity. Based on an analysis of the temperature distribution and emissions, PSR model predictions, and equilibrium calculations, the CO formation was found to be related to the mixing patterns and furnace temperature rather than reaction quenching by the heat exchanger. The critical equivalence ratio, or excess air level, which maintains low CO emissions is reported for different heat exchanger positions, and an optimum operating condition is identified. Results of CO and NO{sub x} emissions, together with visual observations and a simplified two-dimensional analysis of the furnace aerodynamics, demonstrate that fuel jet momentum controls the stability of this multiple jet system. A stability diagram showing the threshold for stable operation is reported, which is not explained by previous stability criteria. (author)

Incorporating Wind Generation Forecast Uncertainty into Power System Operation, Dispatch, and Unit Commitment Procedures  

DOE Green Energy (OSTI)

In this paper, an approach to evaluate the uncertainties of the balancing capacity, ramping capability, and ramp duration requirements is proposed. The approach includes three steps: forecast data acquisition, statistical analysis of retrospective information, and prediction of grid balancing requirements for a specified time horizon and a given confidence level. Assessment of the capacity and ramping requirements is performed using a specially developed probabilistic algorithm based on histogram analysis, incorporating sources of uncertainty of both continuous (wind and load forecast errors) and discrete (forced generator outages and start-up failures) nature.

Operating experience review - Ventilation systems at Department of Energy Facilities  

Science Conference Proceedings (OSTI)

The Office of Special Projects (DP-35), formerly Office of Self-Assessment (DP-9), analyzed occurrences caused by problems with equipment and material and recommended the following systems for an in-depth study: (1) Selective Alpha Air Monitor (SAAM), (2) Emergency Diesel Generator, (3) Ventilation System, (4) Fire Alarm System. Further, DP-35 conducted an in-depth review of the problems associated with SAAM and with diesel generators, and made several recommendations. This study focusses on ventilation system. The intent was to determine the causes for the events related to these system that were reported in the Occurrence Reporting and Processing System (ORPS), to identify components that failed, and to provide technical information from the commercial and nuclear industries on the design, operation, maintenance, and surveillance related to the system and its components. From these data, sites can develop a comprehensive program of maintenance management, including surveillance, to avoid similar occurrences, and to be in compliance with the following DOE orders.

Requirements for Computer Based-Procedures for Nuclear Power Plant Field Operators Results from a Qualitative Study  

SciTech Connect

Although computer-based procedures (CBPs) have been investigated as a way to enhance operator performance on procedural tasks in the nuclear industry for almost thirty years, they are not currently widely deployed at United States utilities. One of the barriers to the wide scale deployment of CBPs is the lack of operational experience with CBPs that could serve as a sound basis for justifying the use of CBPs for nuclear utilities. Utilities are hesitant to adopt CBPs because of concern over potential costs of implementation, and concern over regulatory approval. Regulators require a sound technical basis for the use of any procedure at the utilities; without operating experience to support the use CBPs, it is difficult to establish such a technical basis. In an effort to begin the process of developing a technical basis for CBPs, researchers at Idaho National Laboratory are partnering with industry to explore CBPs with the objective of defining requirements for CBPs and developing an industry-wide vision and path forward for the use of CBPs. This paper describes the results from a qualitative study aimed at defining requirements for CBPs to be used by field operators and maintenance technicians.

MACHINE PROTECTION SYSTEM FOR CONCURRENT OPERATION OF RHIC AND BLIP.  

SciTech Connect

The Brookhaven 200MeV linac is a multipurpose machine used to inject low intensity polarized protons for RHIC (Relativistic Heavy Ion Collider), as well as to inject high intensity protons to BLIP (Brookhaven Linac Isotope Producer), a medical isotope production facility. If high intensity protons were injected to RHIC by mistake, administrative radiation limits could be exceeded or sensitive electronics could be damaged. In the past, the changeover from polarized proton to high intensity proton operation has been a lengthy process, thereby never allowing the two programs to run simultaneously. To remedy this situation and allow concurrent operation of RHIC and BLIP, an active interlock system has been designed to monitor current levels in the AGS using two current transformers with fail safe circuitry and associated electronics to inhibit beam to RHIC if high intensity currents are detected.

Operational and Regulatory Performance of Waste Crate Assay Systems at RFETS  

SciTech Connect

As Rocky Flats Environmental Technology Site (RFETS) approaches its closure target of 2006 emphasis for Non-Destructive Assay (NDA) has shifted from small waste package assay systems towards larger systems that are designed to accommodate Standard Waste Boxes (SWB) and larger Low Level Waste (LLW) containers. To this end, Kaiser Hill, with the support of BNFL Instruments, Inc. (BII) and Los Alamos National Laboratory (LANL), has recently deployed two new crate assay systems. These systems provide the capacity to meet the assay requirements associated with the Deactivation and Decommissioning (D&D) at RFETS. The Super High Efficiency Neutron Coincidence Counting System (SuperHENC) was designed and fabricated as a collaborative effort between RFETS, LANL and BII. The purpose of this counter is to provide a WIPP certified assay capability for SWBs with a sensitivity that allows for TRU/LLW sorting. The SuperHENC has been in operation since early 2001. The BII Multi-Purpose Crate Counter (MPCC) is based on the Imaging Passive Active Neutron (IPAN) technology. This counter was designed to provide diverse capacity for WIPP certified assay of SWBs and to provide assay capability for larger LLW crates that are generated at RFETS. The MPCC has been in operation since early 2002. In order to meet the requirement for measurement of the WIPP tracked radionuclides, both systems incorporate a BII Gamma Energy Analysis sub-system. The unique Energy Times Attenuation (ETA) method is used to provide isotopic mass fractions for diverse waste streams. These systems were the first, and at this time the only, waste crate assay systems that have achieved WIPP certification. This represents a significant achievement given that the performance criteria applied to the measurements of large crates is identical to the criteria for 55-gallon (208 liter) drums. They are now both fully operational at RFETS and continue to successfully support the site closure mission.

Technical Specification action statements requiring shutdown. A risk perspective with application to the RHR/SSW systems of a BWR  

SciTech Connect

When safety systems fail during power operation, the limiting conditions for operation (LCOs) and associated action statements of technical specifications typically require that the plant be shut down within the limits of allowed outage time (AOT). However, when a system needed to remove decay heat, such as the residual heat removal (RHR) system, is inoperable or degraded, shutting down the plant may not necessarily be preferable, from a risk perspective, to continuing power operation over a usual repair time, giving priority to the repairs. The risk impact of the basic operational alternatives, i.e., continued operation or shutdown, was evaluated for failures in the RHR and standby service water (SSW) systems of a boiling-water reactor (BWR) nuclear power plant. A complete or partial failure of the SSW system fails or degrades not only the RHR system but other front-line safety systems supported by the SSW system. This report presents the methodology to evaluate the risk impact of LCOs and associated AOT; the results of risk evaluation from its application to the RHR and SSW systems of a BWR; the findings from the risk-sensitivity analyses to identify alternative operational policies; and the major insights and recommendations to improve the technical specifications action statements.

Design, operation, and evaluation of the transportable vitrification system  

SciTech Connect

The Transportable Vitrification System (TVS) is a transportable melter system designed to demonstrate the treatment of low-level and mixed hazardous and radioactive wastes such as wastewater treatment sludges, contaminated soils and incinerator ash. The TVS is a large-scale, fully integrated vitrification system consisting of melter feed preparation, melter, offgas, service, and control modules. The TVS was tested with surrogate waste at the Clemson University Environmental Systems Engineering Department`s (ESED) DOE/Industry Center for Vitrification Research prior to being shipped to the DOE Oak Ridge Reservation (ORR) K-25 site for treatment of mixed waste. This testing, along with additional testing at ORR, proved that the TVS would be able to successfully treat mixed waste. These surrogate tests consistently produced glass that met the EPA Toxicity Characteristic Leaching Procedure (TCLP). Performance of the system resulted in acceptable emissions of regulated metals from the offgas system. The TVS is scheduled to begin mixed waste operations at ORR in June 1997.

Standard Hydrogen Monitoring System-C operation and maintenance manual  

DOE Green Energy (OSTI)

The primary function of the SHMS-C is to monitor specifically for hydrogen in the waste tank vapor space which may also contain (but not be limited to) unknown quantities of air, nitrous oxide (N{sub 2}O), ammonia (NH{sub 3}), water vapor, carbon dioxide (CO{sub 2}), carbon monoxide (CO) and other gaseous constituents. An electronically controlled grab sampler has replaced the manually operated sample system that was used in the original SHMS enclosure. Samples can now be operator or automatically initiated. Automatic initiation occurs based on the high hydrogen alarm level. Once a sample is obtained it is removed from the sampler and transported to a laboratory for analysis. This system is used to identify other gaseous constituents which are not measured by the hydrogen monitor. The design does not include any remote data acquisition or remote data logging equipment but provides a 4--20 mA dc process signals, and discrete alarm contacts, that can be utilized for remote data logging and alarming when desired. The SHMS-C arrangement consists of design modifications (piping, valves, filters, supports) to the SHMS-B arrangement necessary for the installation of a dual column gas chromatograph and associated sample and calibration gas lines. The gas chromatograph will provide real time, analytical quality, specific hydrogen measurements in low and medium range concentrations. The system is designed to sample process gases that are classified by NEC code as Class 1, Division 1, Group B.

A COMPUTER-ASSIST MATERIAL TRACKING SYSTEM AS A CRITICALITY SAFETY AID TO OPERATORS  

SciTech Connect

In today's compliant-driven environment, fissionable material handlers are inundated with work control rules and procedures in carrying out nuclear operations. Historically, human errors are one of the key contributors of various criticality accidents. Since moving and handling fissionable materials are key components of their job functions, any means that can be provided to assist operators in facilitating fissionable material moves will help improve operational efficiency and enhance criticality safety implementation. From the criticality safety perspective, operational issues have been encountered in Lawrence Livermore National Laboratory (LLNL) plutonium operations. Those issues included lack of adequate historical record keeping for the fissionable material stored in containers, a need for a better way of accommodating operations in a research and development setting, and better means of helping material handlers in carrying out various criticality safety controls. Through the years, effective means were implemented including better work control process, standardized criticality control conditions (SCCC) and relocation of criticality safety engineers to the plutonium facility. Another important measure taken was to develop a computer data acquisition system for criticality safety assessment, which is the subject of this paper. The purpose of the Criticality Special Support System (CSSS) is to integrate many of the proven operational support protocols into a software system to assist operators with assessing compliance to procedures during the handling and movement of fissionable materials. Many nuclear facilities utilize mass cards or a computer program to track fissionable material mass data in operations. Additional item specific data such as, the presence of moderators or close fitting reflectors, could be helpful to fissionable material handlers in assessing compliance to SCCC's. Computer-assist checking of a workstation material inventory against the designated SCCC to enhance the material movement was also recognized. The following three additional functions of the CSSS were requested by operational personnel: additional record keeping, assisting room inventory Material at Risk (MAR) calculations and generating the material label to be placed on a storage can. In 1998, a preliminary CSSS concept was presented to all key stakeholders for the feasibility of such an application. Subsequently, the CSSS was developed with full participation of all stakeholders including fissionable material handlers. In 2003, five CSSS workstations were deployed in the plutonium facility for beta testing and resolving any issues from the field uses. Currently, the CSSS is deployed in all laboratories in the LLNL Plutonium Facility. Initial deployment consists of only a few of the full system functions described in this paper. Final deployment of all functions will take a few more years to assure the system meets quality assurance requirements of a safety significant system.

Effects of construction and operation of a satellite power system upon the magnetosphere  

DOE Green Energy (OSTI)

This is the final report of an initial assessment of magnetospheric effects of the construction and operation of a satellite power system. This assessment effort is based on application of present scientific knowledge rather than on original scientific research. As such, it appears that mass and energy injections of the system are sufficient to modify the magnetosphere substantially, to the extent of possibly requiring mitigation measures for space systems but not to the extent of causing major redirection of efforts and concepts. The scale of the SPS is so unprecedentedly large, however, that these impressions require verification (or rejection) by in-depth assessment based on scientific treatment of the principal issues. Indeed, it is perhaps appropriate to state that present ignorance far exceeds present knowledge in regard to SPS magnetospheric effects, even though we only seek to define the approximate limits of magnetospheric modifications here.

Hydraulically-activated operating system for an electric circuit breaker  

DOE Patents (OSTI)

This operating system comprises a fluid motor having a piston, a breaker-opening space at one side of the piston, and a breaker-closing space at its opposite side. An accumulator freely communicates with the breaker-opening space for supplying pressurized fluid thereto during a circuit-breaker opening operation. A normally-closed valve located on the breaker-closing-side of the piston is openable to release liquid from the breaker-closing space so that pressurized liquid in the breaker-opening space can drive the piston in an opening direction. Means is provided for restoring the valve to its closed position following the circuit-breaker opening operation. An impeded passage affords communication between the accumulator and the breaker-closing space to allow pressurized liquid to flow from the accumulator to the breaker-closing space and develop a pressure therein substantially equal to accumulator pressure when the valve is restored to closed position following breaker-opening. This passage is so impeded that the flow therethrough from the accumulator into the breaker-closing space is sufficiently low during initial opening motion of the piston through a substantial portion of its opening stroke as to avoid interference with said initial opening motion of the piston.

Improve Boiler System Operations- Application of Statistical Process Control  

E-Print Network (OSTI)

The Utilities Department provides utility services to Monsanto and Cain Chemical Company production units at Chocolate Bayou. Over two years ago the department recognized that a significant reduction in waste and rework could be achieved by improving steam boiler and boiler feedwater system operations. The processes were experiencing high maintenance cost due to metering pump and analyzer failures, equipment failures and fouling due to poor control of chemical treatment, and steam vent losses due to unproven system reliability. The team used statistical process control to prevent overadjustment of the process, identified special causes, interviewed customers and applied the ten steps to quality improvement. Results include a six-fold reduction in process variability, $2.3 million/year cost reduction, and improved reliability and customer relations.

Fermilab Main Injector Collimation Systems: Design, Commissioning and Operation  

Science Conference Proceedings (OSTI)

The Fermilab Main Injector is moving toward providing 400 kW of 120 GeV proton beams using slip stacking injection of eleven Booster batches. Loss of 5% of the beam at or near injection energy results in 1.5 kW of beam loss. A collimation system has been implemented to localize this loss with the design emphasis on beam not captured in the accelerating RF buckets. More than 95% of these losses are captured in the collimation region. We will report on the construction, commissioning and operation of this collimation system. Commissioning studies and loss measurement tools will be discussed. Residual radiation monitoring of the Main Injector machine components will be used to demonstrate the effectiveness of these efforts.

Incorporating Uncertainty of Wind Power Generation Forecast into Power System Operation, Dispatch, and Unit Commitment Procedures  

Science Conference Proceedings (OSTI)

An approach to evaluate the uncertainties of the balancing capacity, ramping capability, and ramp duration requirements is proposed. The approach includes three steps: forecast data acquisition, statistical analysis of retrospective information, and prediction of grid balancing requirements for a specified time horizon and a given confidence level. An assessment of the capacity and ramping requirements is performed using a specially developed probabilistic algorithm based on histogram analysis, incorporating sources of uncertainty - both continuous (wind and load forecast errors) and discrete (forced generator outages and start-up failures). A new method called the 'flying-brick' technique is developed to evaluate the look-ahead required generation performance envelope for the worst case scenario within a user-specified confidence level. A self-validation process is used to validate the accuracy of the confidence intervals. To demonstrate the validity of the developed uncertainty assessment methods and its impact on grid operation, a framework for integrating the proposed methods with an EMS system is developed. Demonstration through EMS integration illustrates the applicability of the proposed methodology and the developed tool for actual grid operation and paves the road for integration with EMS systems in control rooms.

Smart Infrared Inspection System Field Operational Test Final Report  

SciTech Connect

The Smart InfraRed Inspection System (SIRIS) is a tool designed to assist inspectors in determining which vehicles passing through the SIRIS system are in need of further inspection by measuring the thermal data from the wheel components. As a vehicle enters the system, infrared cameras on the road measure temperatures of the brakes, tires, and wheel bearings on both wheel ends of commercial motor vehicles (CMVs) in motion. This thermal data is then presented to enforcement personal inside of the inspection station on a user friendly interface. Vehicles that are suspected to have a violation are automatically alerted to the enforcement staff. The main goal of the SIRIS field operational test (FOT) was to collect data to evaluate the performance of the prototype system and determine the viability of such a system being used for commercial motor vehicle enforcement. From March 2010 to September 2010, ORNL facilitated the SIRIS FOT at the Greene County Inspection Station (IS) in Greeneville, Tennessee. During the course of the FOT, 413 CMVs were given a North American Standard (NAS) Level-1 inspection. Of those 413 CMVs, 384 were subjected to a SIRIS screening. A total of 36 (9.38%) of the vehicles were flagged by SIRIS as having one or more thermal issues; with brakes issues making up 33 (91.67%) of those. Of the 36 vehicles flagged as having thermal issues, 31 (86.11%) were found to have a violation and 30 (83.33%) of those vehicles were placed out-of-service (OOS). Overall the enforcement personnel who have used SIRIS for screening purposes have had positive feedback on the potential of SIRIS. With improvements in detection algorithms and stability, the system will be beneficial to the CMV enforcement community and increase overall trooper productivity by accurately identifying a higher percentage of CMVs to be placed OOS with minimal error. No future evaluation of SIRIS has been deemed necessary and specifications for a production system will soon be drafted.

A Systems Engineering Framework for Design, Construction and Operation of the Next Generation Nuclear Plant  

DOE Green Energy (OSTI)

Not since the International Space Station has a project of such wide participation been proposed for the United States. Ten countries, the European Union, universities, Department of Energy (DOE) laboratories, and industry will participate in the research and development, design, construction and/or operation of the fourth generation of nuclear power plants with a demonstration reactor to be built at a DOE site and operational by the middle of the next decade. This reactor will be like no other. The Next Generation Nuclear Plant (NGNP) will be passively safe, economical, highly efficient, modular, proliferation resistant, and sustainable. In addition to electrical generation, the NGNP will demonstrate efficient and cost effective generation of hydrogen to support the President’s Hydrogen Initiative. To effectively manage this multi-organizational and technologically complex project, systems engineering techniques and processes will be used extensively to ensure delivery of the final product. The technological and organizational challenges are complex. Research and development activities are required, material standards require development, hydrogen production, storage and infrastructure requirements are not well developed, and the Nuclear Regulatory Commission may further define risk-informed/performance-based approach to licensing. Detailed design and development will be challenged by the vast cultural and institutional differences across the participants. Systems engineering processes must bring the technological and organizational complexity together to ensure successful product delivery. This paper will define the framework for application of systems engineering to this $1.5B - $1.9B project.

Impact of dispersed solar and wind systems on electric distribution planning and operation  

SciTech Connect

Small-scale dispersed solar photovoltaic and wind generation (DSW) will affect the generation, transmission, and distribution systems of an electric utility. This study examines the technical and economic impacts of dispersing DSW devices within the distribution system. Dispersed intermittent generation is included. Effects of DSW devices on capital investments, reliability, operating and maintenance costs, protection requirements, and communication and control requirements are examined. A DSW operation model is developed to help determine the dependable capacity of fluctuating solar photovoltaic and wind generation as part of the distribution planning process. Specific case studies using distribution system data and renewable resource data for Southern California Edison Company and Consumers Power Company are analyzed to gain insights into the effects of interconnecting DSW devices. The DSW devices were found to offer some distribution investment savings, depending on their availability during peak loads. For a summer-peaking utility, for example, dispersing photovoltaic systems is more likely to defer distribution capital investments than dispersing wind systems. Dispersing storage devices to increase DSW's dependable capacity for distribution systems needs is not economically attractive. Substation placement of DSW and storage devices is found to be more cost effective than feeder or customer placement. Examination of the effects of DSW on distribution system operation showed that small customer-owned DSW devices are not likely to disrupt present time-current distribution protection coordination. Present maintenance work procedures, are adequate to ensure workmen's safety. Regulating voltages within appropriate limits will become more complex with intermittent generation along the distribution feeders.

SciTech Connect

The MTL`s function is to test prototype and industrially manufactured magnets for the Superconducting Super Collider Laboratory (SSCL). The cryogenic system of the MTL has a main refrigeration system consisting of a two-stage compression system, a refrigerator/liquefier coldbox, a liquid helium dewar, warm gas storage, and a regeneration skid. The MTL cryogenic system also includes the following auxiliary equipment: two cleaning, cooling, warmup and purification (CCWP) coldbox modules with a regeneration skid for the charcoal beds, two CCWP compressors, a dehydration skid with its own regeneration system, a pump box, a refrigeration recovery unit, and five distribution boxes. At any given time, the refrigeration system has the capacity to simultaneously test at least six magnets under normally required testing conditions. Every magnet will undergo cleaning, cooldown, and filling prior to general testing, conditioning, quench testing, and other experiments. At the completion of general testing, etc., the magnet must be emptied prior to warming it up to ambient temperature. Furthermore, conditioning, training, and testing of the magnets can be carried out at different temperatures between 4.5 K and 2.5 K. The cryogenic system is designed to test multiple magnets, not all of which are necessarily in the same preparational or operational stage. This paper describes the different operational modes and the behavior and control of the total cryogenic system during multiple magnet tests.

Incorporation of system operation strategies in water rights modeling and analysis  

E-Print Network (OSTI)

of the state of Texas. Effective management of this stochastic resource requires that the availability of water for various uses be estimated to a high degree of confidence. The availability of water is constrained by a variety of hydrologic, physical, environmental, and institutional factors. The adoption of the doctrine of prior appropriation by the state of Texas and the administration of the associated system of water rights places a significant institutional constraint upon the availability of water in the state. This thesis describes a generalized river basin simulation model (TAMUWRAP) capable of analyzing the hydrologic and institutional availability of water to specific users under a prior appropriative system of water rights. The model analyzes the availability of water to individual water rights considering system reservoir operations, return flows, hydroelectric power generation, negative incremental inflows between basin locations, and buffer zone operations. The model can also determine the availability of water to groups of water rights with multiple dates of priority and storage in multiple reservoirs. A case study applying TAMUWRAP to the Brazos River Basin in Texas is presented. The effects of various model options upon simulation results are demonstrated, concentrating on the system of reservoirs and water right permits owned by the Brazos River Authority. The effects of the incorporation of a system reservoir operating permit into the Texas water rights permit structure is investigated. Study results indicate that the Bmws River Authority benefits from conjunctive operation of its system of reservoir and might be able to increase its annual permitted diversion amount with a system permit.

Reactor technology: power conversion systems and reactor operation and maintenance  

SciTech Connect

The use of advanced fuels permits the use of coolants (organic, high pressure helium) that result in power conversion systems with good thermal efficiency and relatively low cost. Water coolant would significantly reduce thermal efficiency, while lithium and salt coolants, which have been proposed for DT reactors, will have comparable power conversion efficiencies, but will probably be significantly more expensive. Helium cooled blankets with direct gas turbine power conversion cycles can also be used with DT reactors, but activation problems will be more severe, and the portion of blanket power in the metallic structure will probably not be available for the direct cycle, because of temperature limitations. A very important potential advantage of advanced fuel reactors over DT fusion reactors is the possibility of easier blanket maintenance and reduced down time for replacement. If unexpected leaks occur, in most cases the leaking circuit can be shut off and a redundant cooling curcuit will take over the thermal load. With the D-He/sup 3/ reactor, it appears practical to do this while the reactor is operating, as long as the leak is small enough not to shut down the reactor. Redundancy for Cat-D reactors has not been explored in detail, but appears feasible in principle. The idea of mobile units operating in the reactor chamber for service and maintenance of radioactive elements is explored.

Review of the IEEE Standard for Computerized Operating Procedure Systems  

SciTech Connect

Increasingly nuclear power plant procedures, such as emergency operating procedures, are being presented in computer form with functionality to support operator use and management of the procedures. The U.S. Nuclear Regulatory Commission (NRC) currently has guidance for the review of computer-based procedures (CBPs); however, there remain CBP functions and human performance issues for which up-to-date guidance is lacking. The Institute of Electrical and Electronics Engineers (IEEE) has initiated a standard development effort to address the human factors engineering (HFE) aspects of CBP systems. When completed, it may provide guidance to supplement the NRC staff's review criteria. The purpose of our study was to evaluate the suitability of the IEEE Standard for use in the NRC's HFE safety reviews of CBP systems and to ensure that the guidance meets the NRC's standard for scientific and engineering rigor used in its own guidance development efforts. We established the following criteria with which to evaluate the Standard: (1) it should meet an existing need of NRC reviewers, (2) it should be based in sound HFE principles, (3) it should be thoroughly peer-reviewed, and (4) it should address CBP-related human performance issues identified in the literature. This report describes the methodology we used to evaluate each criterion. Our evaluation concluded that the Standard generally does meet these criteria, however several areas were identified for which additional clarifications are needed. Thus consideration of the Standard's use by the NRC is supported. The standard evaluation methodology developed in this study can be generally applied to the review of other HFE standards being considered for possible use or endorsement by the NRC.

Hazards and operability study for the surface moisture monitoring system  

SciTech Connect

The Hanford Nuclear Reservation Tank Farms` underground waste tanks have been used to store liquid radioactive waste from defense materials production since the 1940`s. Waste in certain of the tanks may contain material in the form of ferrocyanide or various organic compounds which could potentially be susceptible to condensed phase chemical reactions. Because of the presence of oxidizing materials (nitrate compounds) and heat sources (radioactive decay and chemical reactions), the ferrocyanide or organic material could potentially fuel a propagating exothermic reaction with undesirable consequences. Analysis and experiments indicate that the reaction propagation and/or initiation may be prevented by the presence of sufficient moisture in the waste. Because the reaction would probably be initiated at the surface of the waste, evidence of sufficient moisture concentration would help provide evidence that the tank waste can continue to be safely stored. The Surface Moisture Measurement System (SMMS) was developed to collect data on the surface moisture in the waste by inserting two types of probes (singly) into a waste tank-a neutron probe and an electromagnetic inductance (EMI) probe. The sensor probes will be placed on the surface of the waste utilizing a moveable deployment arm to lower them through an available riser. The movement of the SMMS within the tank will be monitored by a camera lowered through an adjacent riser. The SMMS equipment is the subject of this study. Hazards and Operability Analysis (HAZOP) is a systematic technique for assessing potential hazards and/or operability problems for a new activity. It utilizes a multidiscipline team of knowledgeable individuals in a systematic brainstorming effort. The results of this study will be used as input to an Unreviewed Safety Question determination.

Columbia River System Operation Review : Final Environmental Impact Statement, Appendix R: Pacific Northwest Coordination agreement (PNCA).  

DOE Green Energy (OSTI)

Currently, the Federal government coordinates the planning and operation of the Federal Columbia River Power System (FCRPS) with projects owned and operated by the region`s non-Federal hydrogenerating utilities pursuant to the Pacific North-west Coordination Agreement (PNCA). The Bureau of Reclamation (Reclamation), the Corps of Engineers (Corps), and the Bonneville Power Administration (BPA) are parties to the PNCA on behalf of the government of the United States. The PNCA is a complex agreement that provides an opportunity for the region`s power producers to maximize the power system`s reliability and economy while meeting their multiple-use objectives. The PNCA does not dictate the operation of the resources it coordinates. It is essentially an accounting mechanism that exchanges the power produced among the parties in order to improve the reliability of the system and reduce regional power costs. Project owners retain complete autonomy to operate as needed to meet their multiple-use requirements. The PNCA was executed in 1964 as an important component of regional plans to maximize the Northwest`s hydro resource capability. Maximization also included the development of storage projects on the Columbia River in Canada pursuant to the terms of the 1964 Columbia River Treaty. Because of the link between power coordination and Treaty issues, the current parties to the PNCA, currently are contemplating entering into a replacement or renewed power coordination agreement. Because the power coordination agreement is a consensual arrangement, its ultimate provisions must be acceptable to all of its signatories. This Appendix R to the Final Environmental Impact Statement of the Columbia River System is a presentation of the Pacific North-west Coordination Agreement.

Hydrogen and Oxygen Gas Monitoring System Design and Operation  

DOE Green Energy (OSTI)

This paper describes pertinent design practices of selecting types of monitors, monitor unit placement, setpoint selection, and maintenance considerations for gas monitors. While hydrogen gas monitors and enriched oxygen atmosphere monitors as they would be needed for hydrogen production experiments are the primary focus of this paper, monitors for carbon monoxide and carbon dioxide are also discussed. The experiences of designing, installing, and calibrating gas monitors for a laboratory where experiments in support of the DOE Nuclear Hydrogen Initiative (NHI) are described along with codes, standards, and regulations for these monitors. Information from the literature about best operating practices is also presented. The NHI program has two types of activities. The first, near-term activity is laboratory and pilot-plant experimentation with different processes in the kilogram per day scale to select the most promising types of processes for future applications of hydrogen production. Prudent design calls for indoor gas monitors to sense any hydrogen leaks within these laboratory rooms. The second, longer-term activity is the prototype, or large-scale plants to produce tons of hydrogen per day. These large, outdoor production plants will require area (or “fencepost”) monitoring of hydrogen gas leaks. Some processes will have oxygen production with hydrogen production, and any oxygen releases are also safety concerns since oxygen gas is the strongest oxidizer. Monitoring of these gases is important for personnel safety of both indoor and outdoor experiments. There is some guidance available about proper placement of monitors. The fixed point, stationary monitor can only function if the intruding gas contacts the monitor. Therefore, monitor placement is vital to proper monitoring of the room or area. Factors in sensor location selection include: indoor or outdoor site, the location and nature of potential vapor/gas sources, chemical and physical data of the gases or vapors, liquids with volatility need sensors near the potential sources of release, nature and concentration of gas releases, natural and mechanical ventilation, detector installation locations not vulnerable to mechanical or water damage from normal operations, and locations that lend themselves to convenient maintenance and calibration. The guidance also states that sensors should be located in all areas where hazardous accumulations of gas may occur. Such areas might not be close to release points but might be areas with restricted air movement. Heavier than air gases are likely to accumulate in pits, trenches, drains, and other low areas. Lighter than air gases are more likely to accumulate in overhead spaces, above drop ceilings, etc. In general, sensors should be located close to any potential sources of major release of gas. The paper gives data on monitor sensitivity and expected lifetimes to support the monitor selection process. Proper selection of indoor and outdoor locations for monitors is described, accounting for the vapor densities of hydrogen and oxygen. The latest information on monitor alarm setpoint selection is presented. Typically, monitors require recalibration at least every six months, or more frequently for inhospitable locations, so ready access to the monitors is an important issue to consider in monitor siting. Gas monitors, depending on their type, can be susceptible to blockages of the detector element (i.e., dus

Beyond climate-smart agriculture: toward safe operating spaces for global food systems  

SciTech Connect

Agriculture is considered to be climate-smart when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development because of its capacity to unite the agendas of the agriculture, development and climate change communities under one brand. In this opinion piece authored by scientists from a variety of international agricultural and climate research communities, we argue that the concept needs to be evaluated critically because the relationship between the three dimensions is poorly understood, such that practically any improved agricultural practice can be considered climate-smart. This lack of clarity may have contributed to the broad appeal of the concept. From the understanding that we must hold ourselves accountable to demonstrably better meet human needs in the short and long term within foreseeable local and planetary limits, we develop a conceptualization of climate-smart agriculture as agriculture that can be shown to bring us closer to safe operating spaces for agricultural and food systems across spatial and temporal scales. Improvements in the management of agricultural systems that bring us significantly closer to safe operating spaces will require transformations in governance and use of our natural resources, underpinned by enabling political, social and economic conditions beyond incremental changes. Establishing scientifically credible indicators and metrics of long-term safe operating spaces in the context of a changing climate and growing social-ecological challenges is critical to creating the societal demand and political will required to motivate deep transformations. Answering questions on how the needed transformational change can be achieved will require actively setting and testing hypotheses to refine and characterize our concepts of safer spaces for social-ecological systems across scales. This effort will demand prioritizing key areas of innovation, such as (1) improved adaptive management and governance of social-ecological systems; (2) development of meaningful and relevant integrated indicators of social-ecological systems; (3) gathering of quality integrated data, information, knowledge and analytical tools for improved models and scenarios in time frames and at scales relevant for decision-making; and (4) establishment of legitimate and empowered science policy dialogues on local to international scales to facilitate decision making informed by metrics and indicators of safe operating spaces.

Unmanned Aerial Vehicle (UAV) Dynamic-Tracking Directional Wireless Antennas for Low Powered Applications that Require Reliable Extended Range Operations in Time Critical Scenarios  

Science Conference Proceedings (OSTI)

The proven value of DOD Unmanned Aerial Vehicles (UAVs) will ultimately transition to National and Homeland Security missions that require real-time aerial surveillance, situation awareness, force protection, and sensor placement. Public services first responders who routinely risk personal safety to assess and report a situation for emergency actions will likely be the first to benefit from these new unmanned technologies. ‘Packable’ or ‘Portable’ small class UAVs will be particularly useful to the first responder. They require the least amount of training, no fixed infrastructure, and are capable of being launched and recovered from the point of emergency. All UAVs require wireless communication technologies for real- time applications. Typically on a small UAV, a low bandwidth telemetry link is required for command and control (C2), and systems health monitoring. If the UAV is equipped with a real-time Electro-Optical or Infrared (EO/Ir) video camera payload, a dedicated high bandwidth analog/digital link is usually required for reliable high-resolution imagery. In most cases, both the wireless telemetry and real-time video links will be integrated into the UAV with unity gain omni-directional antennas. With limited on-board power and payload capacity, a small UAV will be limited with the amount of radio-frequency (RF) energy it transmits to the users. Therefore, ‘packable’ and ‘portable’ UAVs will have limited useful operational ranges for first responders. This paper will discuss the limitations of small UAV wireless communications. The discussion will present an approach of utilizing a dynamic ground based real-time tracking high gain directional antenna to provide extend range stand-off operation, potential RF channel reuse, and assured telemetry and data communications from low-powered UAV deployed wireless assets.

Hydraulically-actuated operating system for an electric circuit breaker  

DOE Patents (OSTI)

This hydraulically-actuated operating system comprises a cylinder, a piston movable therein in an opening direction to open a circuit breaker, and an accumulator for supplying pressurized liquid to a piston-actuating space within the cylinder. A normally-closed valve between the accumulator and the actuating space is openable to allow pressurized liquid from the accumulator to flow through the valve into the actuating space to drive the piston in an opening direction. A vent is located hydraulically between the actuating space and the valve for affording communication between said actuating space and a low pressure region. Flow control means is provided for restricting leakage through said vent to a rate that prevents said leakage from substantially detracting from the development of pressure within said actuatng space during the period from initial opening of the valve to the time when said piston has moved through most of its opening stroke. Following such period and while the valve is still open, said flow control means allows effective leakage through said vent. The accumulator has a limited capacity that results in the pressure within said actuating space decaying promptly to a low value as a result of effective leakage through said vent after the piston has moved through a circuit-breaker opening stroke and while the valve is in its open state. Means is provided for resetting the valve to its closed state in response to said pressure decay in the actuating space.

Pressurized reactor system and a method of operating the same  

DOE Patents (OSTI)

A method and apparatus are provided for operating a pressurized reactor system in order to precisely control the temperature within a pressure vessel in order to minimize condensation of corrosive materials from gases on the surfaces of the pressure vessel or contained circulating fluidized bed reactor, and to prevent the temperature of the components from reaching a detrimentally high level, while at the same time allowing quick heating of the pressure vessel interior volume during start-up. Superatmospheric pressure gas is introduced from the first conduit into the fluidized bed reactor and heat derived reactions such as combustion and gassification are maintained in the reactor. Gas is exhausted from the reactor and pressure vessel through a second conduit. Gas is circulated from one part of the inside volume to another to control the temperature of the inside volume, such as by passing the gas through an exterior conduit which has a heat exchanger, control valve, blower and compressor associated therewith, or by causing natural convection flow of circulating gas within one or more generally vertically extending gas passages entirely within the pressure vessel (and containing heat exchangers, flow rate control valves, or the like therein). Preferably, inert gas is provided as a circulating gas, and the inert gas may also be used in emergency shut-down situations. In emergency shut-down reaction gas being supplied to the reactor is cut off, while inert gas from the interior gas volume of the pressure vessel is introduced into the reactor.

Preferably, inert gas is provided as a circulating gas, and the inert gas may also be used in emergency shut-down situations. In emergency shut-down reaction gas being supplied to the reactor is cut off, while inert gas from the interior gas volume of the pressure vessel is introduced into the reactor. 2 figs.

Alternatives generation and analysis for the Phase I intermediate waste feed staging system design requirements  

SciTech Connect

This alternatives generation and analysis (AGA) addresses the question: What is the design basis for the facilities required to stage low-level waste (LLW) feed to the Phase I private contractors? Alternative designs for the intermediate waste feed staging system were developed, analyzed, and compared. Based on these analyses, this document recommends installing mixer pumps in the central pump pit of double-shell tanks 241-AP-102 and 241-AP-104. Also recommended is installing decant/transfer pumps at these tanks. These recommendations have clear advantages in that they provide a low shedule impact/risk and the highest operability of all the alternatives investigated. This revision incorporates comments from the decision board.

HEMP emergency planning and operating procedures for electric power systems. Power Systems Technology Program  

SciTech Connect

Investigations of the impact of high-altitude electromagnetic pulse (HEMP) on electric power systems and electrical equipment have revealed that HEMP creates both misoperation and failures. These events result from both the early time E{sub 1} (steep-front pulse) component and the late time E{sub 3} (geomagnetic perturbations) component of HEMP. In this report a HEMP event is viewed in terms of its marginal impact over classical power system disturbances by considering the unique properties and consequences of HEMP. This report focuses on system-wide electrical component failures and their potential consequences from HEMP. In particular, the effectiveness of planning and operating procedures for electric systems is evaluated while under the influence of HEMP. This assessment relies on published data and characterizes utilities using the North American Electric Reliability Council`s regions and guidelines to model electric power system planning and operations. Key issues addressed by the report include how electric power systems are affected by HEMP and what actions electric utilities can initiate to reduce the consequences of HEMP. The report also reviews the salient features of earlier HEMP studies and projects, examines technology trends in the electric power industry which are affected by HEMP, characterizes the vulnerability of power systems to HEMP, and explores the capability of electric systems to recover from a HEMP event.

CGI-844: 100-K coolant back-up system scope requirements  

SciTech Connect

Several decisions regarding basic project philosophy must be made in order to proceed with scope design and the preparation of equipment procurement specifcations. The purpose of this document is to present as much pertinent data as possible to allow the project representatives to become familiar with the problems involved. A meeting of Representatives is planned for the near future after receipt of project authorization to discuss the scope of this project and its relationship to CG-775. Emergency flow requirements of the K reactors for planned future power levels is approximately 32,000 gpm within 68 sec. A detailed study of the existing high-pressure cross-tie line reveals that a duplicate cross-tie line and five low lift pump operation would be required to provide this flow. The existing emergency generation capacity is not adequate to supply five low lift pumps and all other necessary emergency electrical loads. A possible solution to adequate emergency flows is to connect the proposed steam turbine pump directly to the risers and to consider the turbine pump as the last ditch system. If it is determined that this does not meet the criteria of separate systems, then an alternate solution must be found.

The electrical system for the Phase 1 privatization facilities will support the TWRS mission by providing the electrical power to the Phase 1 privatized facilities. This system will receive power from the Department of Energy-Richland Operations (RL) A4-8 230 kV transmission system powered from Bonneville Power Administration (BPA) Ashe and Midway 230 kV Substations. The existing RL 230 kV transmission line will be modified and looped 1021 into the new 230 kV substation bus. The new substation will be located in the vicinity of the privatized facilities, approximately 3.2 km (2 mi) south of the existing RL A4-8 230 kV transmission line. The substation will be capable of providing up to 40 MW of electrical power to support the Phase 1 privatization facilities and has space for accommodating future expansions. The substation will require at least two 230-13.8 kV transformers, 13.8 kV split bus switchgear, switchgear building, grounding transformers, instrument transformers, control and monitoring equipment, associated protection and isolation devices, lightning protection, yard lighting, cable and raceways, and infrastructure needed to provide desired availability and reliability. The power from the 13.8 kV switchgear located in the switchgear building will be delivered at the privatization facilities site boundaries. The 13.8 kV distribution system inside the privatization facilities site boundaries is the responsibility of the privatization contract.

The effect of operating temperature on open, multimegawatt space power systems  

Science Conference Proceedings (OSTI)

This study addresses reactor powered and combustion powered multimegawatt, burst mode, space power systems to evaluate the effect turbine inlet temperature will have on their performance and mass. Both systems will provide power to space based antiballistic missile weapons that require hydrogen for cooling, and both use this hydrogen coolant as a working fluid or as a fuel for power generation. The quantity of hydrogen needed for weapon cooling increases as the weapon's cooling load increases and as weapon coolant outlet temperature decreases. Also, the hydrogen needed by the turbines in both power systems increases as turbine inlet temperature decreases. When weapon cooling loads are above 40% to 50% of weapon power and weapon coolant outlet temperature is below 300 K to 400 K, the weapon needs more hydrogen than the turbine in either the reactor or combustion powered systems using turbine inlet temperatures consistent with current material technology. There is therefore very little system mass reduction to be gained by operating a burst mode power system at a turbine inlet temperature above present material temperature limits unless the weapon's cooling load is below 40% to 50% or coolant outlet temperature is above 300 K to 400 K. Furthermore, the combustion system's mass increases as turbine inlet temperature increases because oxygen inventory increases with increased turbine inlet temperature.

GTRI Remote Monitoring System: Training and Operational Needs Assessment Analysis Report  

SciTech Connect

The mission of the United States Department of Energy (DOE) National Nuclear Security Administrations (NNSA's) Global Threat Reduction Initiative (GTRI) is to identify, secure, recover and facilitate the disposition of vulnerable nuclear and high-risk radioactive materials around the world that pose a threat to the United States and the international community. The GTRI's unique mission to reduce and protect vulnerable nuclear and radiological materials located at civilian sites worldwide directly addresses recommendations of the 9/11 Commission1, and is a vital part of the President's National Security Strategy and the Global Initiative. The GTRI Remote Monitoring System (RMS) is a standalone security system that includes radiation and tamper alarms, and CCTV; which can be transmitted securely over the Internet to multiple on-site and off-site locations. Through our experiences during installation of the system at 162 sites, plus feedback received from Alarm Response Training course participants, site input to project teams and analysis of trouble calls; indications were that current system training was lacking and inconsistent. A survey was undertaken to gather information from RMS users across the nation, to evaluate the current level of training and determine what if any improvements needed to be made. Additional questions were focused on the operation of the RMS software. The training survey was initially sent electronically to 245 users at the RMS sites and achieved a 37.6% return rate. Analysis of the resulting data revealed that 34.6% of the respondents had not received training or were unsure if they had, despite the fact that vendor engineers provide training at installation of the system. Any training received was referred to as minimal, and brief, not documented, and nothing in writing. 63.7% of respondents said they were either not at all prepared or only somewhat prepared to use the RMS software required to effectively operate the system. As a result of this analysis, a formal training curriculum will be designed and implemented to include several blended learning delivery options. This training will be piloted at RMS sites; initial training will become a required element of RMS installation and refresher training will be considered for sustainability of operations.

Method for including operation and maintenance costs in the economic analysis of active solar energy systems  

DOE Green Energy (OSTI)

For a developing technology such as solar energy, the costs for operation and maintenance (O and M) can be substantial. In the past, most economic analyses included these costs by simply assuming that an annual cost will be incurred that is proportional to the initial cost of the system. However, in assessing the economics of new systems proposed for further research and development, such a simplification can obscure the issues. For example, when the typical method for including O and M costs in an economic analysis is used, the O and M costs associated with a newly developed, more reliable, and slightly more expensive controller will be assumed to increase - an obvious inconsistency. The method presented in this report replaces this simplistic approach with a representation of the O and M costs that explicitly accounts for the uncertainties and risks inherent in the operation of any equipment. A detailed description of the data inputs required by the method is included as well as a summary of data sources and an example of the method as applied to an active solar heating system.

On the Development of Object-Oriented Operating Systems for Deeply Embedded Systems - The PURE Project  

E-Print Network (OSTI)

Introduction Embedded systems are becoming more and more important --- and they are becoming more and more complex. Getting through daily life without being faced with electronically controlled devices is almost unthinkable. This holds not only for the general consumer market regarding cameras, HIFI, kitchen aids, washing machines etc., but also for other markets such as aircraft or automotive industries. Today's limousines, for example, can be considered (large scale) distributed systems on wheels. There are cars in daily operation consisting of over 60 networked processors (i. e. Ż-controllers). Although these systems are quite large with respect to the number of Ż-controllers, they are still small with respect to memory size. In the above mentioned case, 1--2 MB of global memory (for the entire embedded distributed system) is not uncommon --- and this would already be more than luxurious. Typically, a single Ż-controller-based

Architecture and operation of the Z Pulsed Power Facility vacuum system.  

SciTech Connect

The Z Pulsed Power Facility at Sandia National Laboratories in Albuquerque, New Mexico, USA is one of the world's premier high energy density physics facilities. The Z Facility derives its name from the z-pinch phenomena which is a type of plasma confinement system that uses the electrical current in the plasma to generate a magnetic field that compresses it. Z refers to the direction of current flow, the z axis in a three dimensional Cartesian coordinate system. The multiterawatt, multimegajoule electrical pulse the Facility produces is 100-400 nanoseconds in time. Research and development programs currently being conducted on the Z Facility include inertial confinement fusion, dynamic material properties, laboratory astrophysics and radiation effects. The Z Facility vacuum system consists of two subsystems, center section and load diagnostics. Dry roughing pumps and cryogenic high vacuum pumps are used to evacuate the 40,000 liter, 200 square meter center section of the facility where the experimental load is located. Pumping times on the order of two hours are required to reduce the pressure from atmospheric to 10{sup -5} Torr. The center section is cycled from atmosphere to high vacuum for each experiment. The facility is capable of conducting one to two experiments per day. Numerous smaller vacuum pumping systems are used to evacuate load diagnostics. The megajoules of energy released during an experiment causes damage to the Facility that presents numerous challenges for reliable operation of the vacuum system.

An Operator Perspective from a Facility Evaluation of an RFID-Based UF6 Cylinder Accounting and Tracking System  

SciTech Connect

An operational field test of a Radio-Frequency Identification (RFID) system for tracking and accounting UF6 cylinders was conducted at the Global Nuclear Fuel Americas (GNF) fuel fabrication plant in 2009. The Cylinder Accountability and Tracking System (CATS) was designed and deployed by Oak Ridge National Laboratory (ORNL) and evaluated in cooperation with GNF. The system required that passive RFID be attached to several UF6 30B cylinders as they were received at the site; then the cylinders were tracked as they proceeded to interim storage, to processing in an autoclave, and eventually to disposition from the site. This CATS deployment also provided a direct integration of scale data from the site accountability scales. The integration of this information into the tracking data provided an attribute for additional safeguards for evaluation. The field test provided insight into the advantages and challenges of using RFID at an operating nuclear facility. The RFID system allowed operators to interact with the technology and demonstrated the survivability of the tags and reader equipment in the process environment. This paper will provide the operator perspective on utilizing RFID technology for locating cylinders within the facility, thereby tracking the cylinders for process and for Material Control & Accounting functions. The paper also will present the operator viewpoint on RFID implemented as an independent safeguards system.

Operational Challenges in Gas-To-Liquid (GTL) Transportation Through Trans Alaska Pipeline System (TAPS)  

Science Conference Proceedings (OSTI)

Oil production from Alaskan North Slope oil fields has steadily declined. In the near future, ANS crude oil production will decline to such a level (200,000 to 400,000 bbl/day) that maintaining economic operation of the Trans-Alaska Pipeline System (TAPS) will require pumping alternative products through the system. Heavy oil deposits in the West Sak and Ugnu formations are a potential resource, although transporting these products involves addressing important sedimentation issues. One possibility is the use of Gas-to-Liquid (GTL) technology. Estimated recoverable gas reserves of 38 trillion cubic feet (TCF) on the North Slope of Alaska can be converted to liquid with GTL technology and combined with the heavy oils for a product suitable for pipeline transport. Issues that could affect transport of this such products through TAPS include pumpability of GTL and crude oil blends, cold restart of the pipeline following a prolonged winter shutdown, and solids deposition inside the pipeline. This study examined several key fluid properties of GTL, crude oil and four selected blends under TAPS operating conditions. Key measurements included Reid Vapor Pressure, density and viscosity, PVT properties, and solids deposition. Results showed that gel strength is not a significant factor for the ratios of GTL-crude oil blend mixtures (1:1; 1:2; 1:3; 1:4) tested under TAPS cold re-start conditions at temperatures above - 20 F, although Bingham fluid flow characteristics exhibited by the blends at low temperatures indicate high pumping power requirements following prolonged shutdown. Solids deposition is a major concern for all studied blends. For the commingled flow profile studied, decreased throughput can result in increased and more rapid solid deposition along the pipe wall, resulting in more frequent pigging of the pipeline or, if left unchecked, pipeline corrosion.

The Effect of Degraded Digital Instrumentation and Control systems on Human-system Interfaces and Operator Performance  

SciTech Connect

Integrated digital instrumentation and control (I&C) systems in new and advanced nuclear power plants (NPPs) will support operators in monitoring and controlling the plants. Even though digital systems typically are expected to be reliable, their potential for degradation or failure significantly could affect the operators performance and, consequently, jeopardize plant safety. This U.S. Nuclear Regulatory Commission (NRC) research investigated the effects of degraded I&C systems on human performance and on plant operations. The objective was to develop technical basis and guidance for human factors engineering (HFE) reviews addressing the operator's ability to detect and manage degraded digital I&C conditions. We reviewed pertinent standards and guidelines, empirical studies, and plant operating experience. In addition, we evaluated the potential effects of selected failure modes of the digital feedwater control system of a currently operating pressurized water reactor (PWR) on human-system interfaces (HSIs) and the operators performance. Our findings indicated that I&C degradations are prevalent in plants employing digital systems, and the overall effects on the plant's behavior can be significant, such as causing a reactor trip or equipment to operate unexpectedly. I&C degradations may affect the HSIs used by operators to monitor and control the plant. For example, deterioration of the sensors can complicate the operators interpretation of displays, and sometimes may mislead them by making it appear that a process disturbance has occurred. We used the findings as the technical basis upon which to develop HFE review guidance.

Understanding the Impact of Interconnect Failures on System Operation  

Science Conference Proceedings (OSTI)

Hardware failures are inevitable on large high performance computing systems. Faults or performance degradations in the high-speed network can reduce the entire system s performance. Since the introduction of the Gemini interconnect, Cray systems have become resilient to many networking faults that were fatal in their previous generation systems. These new network reliability and resiliency features have enabled higher uptimes on Cray systems by allowing them to continue running with reduced network performance. Oak Ridge National Laboratory has developed a set of user-level diagnostics that stresses the high-speed network and searches for components that are not performing as expected. Nearest-neighbor bandwidth tests check every network chip and network link in the system. Additionally, performance counters stored on the network ASIC s memory mapped registers (MMRs) are used to better understand the state of the network. Applications have also been characterized under various suboptimal network conditions to better understand what impact network problems have on user codes.

High Gradient Operation with the CEBAF Upgrade RF Control System  

SciTech Connect

The CEBAF Accelerator at Jefferson Lab is presently a 6 GeV five pass electron accelerator consisting of two superconducting linacs joined by independent magnetic transport arcs. Energy will be upgraded to 12 GeV with the addition of 10 new high gradient cryomodules (17+ MV/m). The higher gradients pose significant challenges beyond what the present analog low level RF (LLRF) control systems can handle reliably; therefore, a new LLRF control system is needed. A prototype system has been developed incorporating a large FPGA and using digital down and up conversion to minimize the need for analog components. The new system is more flexible and less susceptible to drifts and component nonlinearities. Because resonance control is critical to reach high gradients quickly, the new cryomodules will include a piezoelectric tuner for each cavity, and the LLRF controls must incorporate both feedback and feed-forward methods to achieve optimal resonance control performance. This paper discusses development of the new RF system, system performance for phase and amplitude stability and resonance control under Lorentz detuning measured during recent tests on a prototype cryomodule.

Applying the Systems Engineering Process for Establishing Requirements for the Safety and Health Monitoring System of the Waste Solidification Building at the Savannah River Site  

Science Conference Proceedings (OSTI)

The Safety and Health Monitoring (SHM) System technical basis document for the Waste Solidification Building (WSB) was developed by the Westinghouse Savannah River Company design team. The WSB is being designed and built to support the waste disposal needs of the Pit Disassembly and Conversion Facility (PDCF) and the Mixed Oxide Fuel Fabrication Facility (MFFF) at the Savannah River Site (SRS) in South Carolina. The main mission of the WSB is to process the radiological liquid waste streams from the PDCF and the MFFF into a solid waste form. The solid waste form, concrete encased waste, is acceptable for shipment and disposal as transuranic (TRU) waste at the Waste Isolation Pilot Plant (WIPP) and as Low Level Waste (LLW) at on-site disposal areas. The SHM System will also handle the job control waste from the PDCF, the MFFF, and the WSB. The SHM System will serve the WSB by monitoring personnel radiation exposure and environmental releases. The WSB design used HPT design support in determining the air monitoring equipment required for the WSB. The Systems Engineering (SE) process was applied to define the functions and requirements necessary to design and operate the SHM System. The SE process is a proven disciplined approach that supports management in clearly defining the mission or problem, managing system functions and requirements, identifying and managing risk, establishing bases for informed decision making, and verifying that products and services meet customer needs. This SE process applied to the SHM System was a major effort encompassing requirements analysis and interface control. Use of the SE process combined with HPT design input resulted in well-defined requirements to support the procurement of a safe-mission essential SHM System.

Wind Power Plants and System Operation in the Hourly Time Domain: Preprint  

DOE Green Energy (OSTI)

Because wind is an intermittent power source, the variability may have significant impacts on system operation. Part of the difficulty of analyzing the load following impact of wind is the inadequacy of most modeling frameworks to accurately treat wind plants and the difficulty of untangling causal impacts of wind plants from other dynamic phenomena. This paper presents a simple analysis of an hourly load-following requirement that can be performed without extensive computer modeling. The approach is therefore useful as a first step to quantifying these impacts when extensive modeling and data sets are not available. The variability that wind plants add to the electricity supply must be analyzed in the context of overall system variability. The approach used in this paper does just that. The results show that wind plants do have an impact on load following, but when calculated as a percentage of the installed wind plant capacity, this impact is not large. Another issue is the extent to which wind forecast errors add to imbalance. The relative statistical independence of wind forecast errors and load forecast errors can be used to help quantify the extent to which wind forecast errors impact overall system imbalances.

Extending and automating a Systems-Theoretic hazard analysis for requirements generation and analysis.  

SciTech Connect

Systems Theoretic Process Analysis (STPA) is a powerful new hazard analysis method designed to go beyond traditional safety techniques - such as Fault Tree Analysis (FTA) - that overlook important causes of accidents like flawed requirements, dysfunctional component interactions, and software errors. While proving to be very effective on real systems, no formal structure has been defined for STPA and its application has been ad-hoc with no rigorous procedures or model-based design tools. This report defines a formal mathematical structure underlying STPA and describes a procedure for systematically performing an STPA analysis based on that structure. A method for using the results of the hazard analysis to generate formal safety-critical, model-based system and software requirements is also presented. Techniques to automate both the analysis and the requirements generation are introduced, as well as a method to detect conflicts between the safety and other functional model-based requirements during early development of the system.

Daily/Hourly Hydrosystem Operation : How the Columbia River System Responds to Short-Term Needs.  

SciTech Connect

The System Operation Review, being conducted by the Bonneville Power Administration, the US Army Corps of Engineers, and the US Bureau of Reclamation, is analyzing current and potential future operations of the Columbia River System. One goal of the System Operations Review is to develop a new System Operation Strategy. The strategy will be designed to balance the many regionally and nationally important uses of the Columbia River system. Short-term operations address the dynamics that affect the Northwest hydro system and its multiple uses. Demands for electrical power and natural streamflows change constantly and thus are not precisely predictable. Other uses of the hydro system have constantly changing needs, too, many of which can interfere with other uses. Project operators must address various river needs, physical limitations, weather, and streamflow conditions while maintaining the stability of the electric system and keeping your lights on. It takes staffing around the clock to manage the hour-to-hour changes that occur and the challenges that face project operators all the time.

SystemBurn: Principles of Design and Operation Release 3.0  

SciTech Connect

As high performance computing technology progresses toward the progressively more extreme scales required to address critical computational problems of both national and global interest, power and cooling for these extreme scale systems is becoming a growing concern. A standardized methodology for testing system requirements under maximal system load and validating system environmental capability to meet those requirements is critical to maintaining system stability and minimizing power and cooling risks for high end data centers. Moreover, accurate testing permits the high end data center to avoid issues of under- or over-provisioning power and cooling capacity saving resources and mitigating hazards. Previous approaches to such testing have employed an ad hoc collection of tools, which have been anecdotally perceived to produce a heavy system load. In this report, we present SystemBurn, a software tool engineered to allow a system user to methodically create a maximal system load on large scale systems for the purposes of testing and validation.

An evaluation of the energy systems in a plant can be accomplished by different techniques which require different levels of effort. Three alternatives are described: Rational Analysis, Energy Audits and Energy Management by Utility Systems Metering. A progressively greater investment in time and funding is required; however, the results yield more information and greater accuracy about energy usage. It is recommended that the step beyond Energy Audits, an Energy Management System, be taken. The Energy Management System approach is worthwhile, and the additional time and funding will be returned in energy cost reductions.

Light Emitting Diode (LED) fiducial system: Setup and operation  

SciTech Connect

Streak cameras, either electronic or rotating mirror, are common diagnostic tools used to explore very fast phenomena. Often they are used to precisely time events or durations, and in most cases, it is important to have quality time marks on the film record. Many methods have been used to introduce time marks onto the film. Exploding bridge wires are frequently used, but they light up slowly and are difficult to read with consistent accuracy. It is also difficult to put more than a few bridge wires in the view of a camera slit, so there are only a few timing marks written to the film. In some cases the time scale on the film must be interpolated over long distances, creating a significant loss of accuracy. Interpolation is especially troublesome with those cameras that have a nonlinear sweep rate. Spark gaps located on the camera slit turn on a bit faster, but suffer from the same interpolation induced errors. A series of short duration laser pulses, accurately timed and introduced along the edges of the film, is a very fine solution. The problem with such a laser fiducial system is that the lasers are very expensive and difficult to maintain. There has been a need for many years for an inexpensive, very bright light source that can be repetitively pulsed accurately and with short duration. Various technologies have sufficiently developed over the past few years, allowing us to build a fiducial system based on light emitting diodes (LED) for the Cordin rotating mirror streak cameras.

Operation of a bushing melter system designed for actinide vitrification  

SciTech Connect

The Westinghouse Savannah River Company is developing a melter system to vitrify actinide materials. The melter system will used to vitrify the americium and curium solution which is currently stored in one of the Savannah River Site`s (SRS) processing canyons. This solution is one of the materials designated by the Defense Nuclear Facilities Safety Board (DNFSB) to be dispositioned as part of the DNFSB recommendation 94-1. The Am/Cm solution contains an extremely large fraction (>2 kilograms of Cm and 10 kilograms of Am) of t he United States`s total inventory of both elements. They have an estimated value on the order of one billion dollars - if they are processed through the DOE Isotope Sales program at the Oak Ridge National Laboratory. It is therefore deemed highly desirable to transfer the material to Oak Ridge in a form which can allow for recovery of the material. A commercial glass composition has been demonstrated to be compatible with up to 40 weight percent of the Am/Cm solution contents. This glass is also selectively attacked by nitric acid. This allows the actinide to be recovered by common separation processes.

Investigating Operating System Noise in Extreme-Scale High-Performance Computing Systems using Simulation  

SciTech Connect

Hardware/software co-design for future-generation high-performance computing (HPC) systems aims at closing the gap between the peak capabilities of the hardware and the performance realized by applications (application-architecture performance gap). Performance profiling of architectures and applications is a crucial part of this iterative process. The work in this paper focuses on operating system (OS) noise as an additional factor to be considered for co-design. It represents the first step in including OS noise in HPC hardware/software co-design by adding a noise injection feature to an existing simulation-based co-design toolkit. It reuses an existing abstraction for OS noise with frequency (periodic recurrence) and period (duration of each occurrence) to enhance the processor model of the Extreme-scale Simulator (xSim) with synchronized and random OS noise simulation. The results demonstrate this capability by evaluating the impact of OS noise on MPI_Bcast() and MPI_Reduce() in a simulated future-generation HPC system with 2,097,152 compute nodes.

Engineering task plan for standard hydrogen monitoring system operation  

DOE Green Energy (OSTI)

Tanks that are known or suspected to retain and occasionally release flammable gases are equipped with Standard Hydrogen Monitoring System (SHMS) cabinets. These cabinets contain Whittaker{trademark} electrochemical cells and may also have a gas chromatograph (GC) and/or a Bruel and Kjaer infrared photo-acoustic multi-gas monitor (B and K). The GC and B and K will be referred to collectively as ''analytical instruments'' in this document. Using these instruments, a tank can be monitored for hydrogen, ammonia, methane, and nitrous oxide. Air from the tank vent header (for actively ventilated tanks) or dome space (for passively ventilated tanks) is drawn continuously through the monitoring instruments via a sample pump. This monitoring is performed to track the gas release behavior of selected waste storage tanks and to help identify any potentially serious gas release behavior. Vapor grab samples are obtained from the SHMS as well and are analyzed with a mass spectrometer to obtain concentration data about hydrogen and other gases.
