  3. Are utilities obsolete: a troubled system faces radical change

    SciTech Connect (OSTI)

    Fowley D.

    1984-05-21

    The once-placid electric utility industry has never seen anything like it. As the money tied up in unfinished nuclear power plants has mounted to alarming levels, banks have turned skittish and investors have fled, raising the threat of bankruptcy for some. But the web of troubles enveloping the utility industry reaches far beyond the nuclear basket cases and the hubbub over atomic power. More plant cancellations - coal as well as nuclear - less access to capital markets, and dwindling sympathy from regulators seem in the cards. Most disconcerting of all, the time-honored system of supplying, pricing, regulating, and financing electricity - a system that was not good enough to avert the present crisis - may be outmoded. If the industry cannot be kept viable, some foresee investor-owned utilities going the way of the private urban mass-transit systems, becoming municipal, state, or even federal entities. Defaults or bankruptcies could also lead to greater concentration, with the stronger utilities picking off the weak. Some analysts, in fact, believe that the main threat posed by the current crisis is that no utility, investor, or lender will be willing to risk money to build capacity required in the future - if only to replace retiring plants. Without strong incentives - running counter to today's market forces - rescue mission is unlikely. The modest prospects for demand growth and the poor economics of new plants are relentlessly bringing the era of big central stations to an end.

  11. Is recycling worth the trouble

    SciTech Connect (OSTI)

    Boltz, C.M.

    1995-03-01

    A panel of waste industry experts met recently at a Washington, DC, conference to discuss and debate the costs, benefits, and economics of recycling solid waste. The nearly unanimous conclusion from some of the speakers--that recycling, as it is implemented today, has costs that far outweigh its benefits--is evidence of a growing backlash among solid waste officials against a recycling movement they feel has been grossly over-inflated by environmental groups as a solution to a non-existent problem known as the garbage crisis. The public should not place such a strong emphasis on recycling as a cure-all for environmental problems, according to the panel of four waste management policy analysts at The State of Garbage'' session held in mid-January at the 1995 US/Canadian Federation Solid Waste Management Conference. Moreover, some panel members said, recycling should take place only if it makes economic sense.

  15. Seeking to calm troubled waters: The Missisquoi River Keepers Project and the development of a community-based river protection program

    SciTech Connect (OSTI)

    Peterson, D.M.; Delaney, M.; Dickens, S.P.

    1995-12-01

    The Missisquoi River, in northwestern Vermont and southern Quebec, has become the focus of efforts to develop local community-based means to address environmental and cultural concerns affecting the region`s Native and non-Native peoples. The River flows through historical Abenaki territory, and is relied upon by tribal members for subsistence, cultural, and spiritual purposes. The River has been in a controversy involving aboriginal fishing and sovereignty rights, hydroelectric development, transboundary pollution problems, protection of Native cultural and historical sites, state resource management practices, and formal federal/state recognition of the Abenaki nation. The Missisquoi River Keepers Project is a cooperative program initiated by the Abenaki in 1993 to protect the River and its watershed by uniting often adversarial Native and non-Native communities in the region. This paper discusses how ecological monitoring, environmental and cultural education, community organizing, and outreach to federal, state and local officials are being utilized to identify the watershed`s problems and to resolve conflicts. The Project is working with different interest groups to develop consensus and to find creative means to reverse the degradation of the watershed. The Project has also provided legal and technical support in reviewing environmental permits, rule-making, and enforcement of federal, state and local statutes and regulations. The Project may serve as a useful model forlocal management of watershed protection programs.

  11. Geothermal drilling problems and their impact on cost

    SciTech Connect (OSTI)

    Carson, C.C.

    1982-01-01

    Historical data are presented that demonstrate the significance of unexpected problems. In extreme cases, trouble costs are the largest component of well costs or severe troubles can lead to abandonment of a hole. Drilling experiences from US geothermal areas are used to analyze the frequency and severity of various problems. In addition, average trouble costs are estimated based on this analysis and the relationship between trouble and depth is discussed. The most frequent drilling and completion problem in geothermal wells is lost circulation. This is especially true for resources in underpressured, fractured formations. Serious loss of circulation can occur during drilling - because of this, the producing portions of many wells are drilled with air or aerated drilling fluid and the resulting corrosion/erosion problems are tolerated - but it can also affect the cementing of well casing. Problems in bonding the casing to the formation result from many other causes as well, and are common in geothermal wells. Good bonds are essential because of the possibility of casing collapse due to thermal cycling during the life of the well. Several other problems are identified and their impacts are quantified and discussed.

    2015-10-21

    The City of Detroit is undertaking a comprehensive restoration of its street lighting system that includes transitioning the existing high-pressure sodium (HPS) sources to light-emitting diode (LED). Detroit’s well-publicized financial troubles over the last several years have added many hurdles and constraints to this process. Strategies to overcome these issues have largely been successful, but have also brought some mixed results. This document provides an objective review of the circumstances surrounding the system restoration, the processes undertaken and decisions made, and the results so far.

    SciTech Connect (OSTI)

    Mastromatteo, E.

    1986-10-01

    Nickel was first isolated in impure form in 1751 by Cronstedt from an ore containing niccolite (NiAs). An ore of this type had earlier caused trouble in the smelting of copper and silver in Saxony, yielding an unusually brittle product. This interfering substance was referred to as kupfernick after Old Nick and his mischievous gnomes and Cronstedt applied the name nickel to this new element. The pure metal was first prepared by Richter in 1804 and he described some of the useful properties of nickel. This paper discusses the properties, sources, and toxicity of nickel.

  15. GUIDE FOR POLARIZED NEUTRONS

    DOE Patents [OSTI]

    Sailor, V.L.; Aichroth, R.W.

    1962-12-01

    The plane of polarization of a beam of polarized neutrons is changed by this invention, and the plane can be flipped back and forth quicitly in two directions in a trouble-free manner. The invention comprises a guide having a plurality of oppositely directed magnets forming a gap for the neutron beam and the gaps are spaced longitudinally in a spiral along the beam at small stepped angles. When it is desired to flip the plane of polarization the magnets are suitably rotated to change the direction of the spiral of the gaps. (AEC)

    This report is an analysis of the issues confronting US energy policymakers and the US geothermal industry as the result of the implementation and interpretation of the 1978 Public Utility Regulatory Policies Act, commonly known as PURPA. It seeks to answer four sets of questions about PURPA: (1) What has the existence of PURPA meant to the US geothermal industry. (2) How has the interpretation of PURPA evolved over the past decade. (3) What particular portions of PURPA rule making have been most crucial to the growth and development of the geothermal industry. (4) What aspects of PURPA have been most troubling to utilities purchasing or developing geothermal energy.

    SciTech Connect (OSTI)

    Patel, S.

    2008-11-15

    State-owned Eskom has a near-monopoly on power generation in South Africa. Though one might think government control would make the business of managing power supplies easier, the story of Eskom's recent troubles shows that state ownership, in and of itself, is neither the problem nor the solution. More important than ownership structure are policy and planning decisions that take the long view. Eskom's cautionary tale should remind those involved in the power industry anywhere in the world that, to vary a disclosure from the financial sector that too few have paid attention to, past performance is not a guarantee of future success. 8 figs.

    SciTech Connect (OSTI)

    Hume, M.

    1984-11-12

    Antitrust may be the approach natural gas end users need to gain access to gas transmission when pipelines or utilities allegedly resist carriage. Two pending suits could help ease the way for those who have trouble negotiating contract carriage of their self-help gas, and could help set precedents in similar antitrust suits. The cases involve a Colorade brick company's suit against Colorado Interstate Gas Co. and the State of Illinois' suit against Panhandle Eaton Pipeline Co. The issue is whether pipeline companies violate antitrust laws by refusing to carry fuel in competition with their own sales.

    From tall skyscrapers and flashing neon signs to Buddhist temples and pagodas, South Korea is a mixture of the new and old Asia. Doing its part to help modernise this country, the Boryeong thermal power complex operates six coal-fired 500-MW units that provide electricity to power South Korea's economic growth. One of the important reasons for this facility's overall success is its operational reliability. An example of this is Boryeong Unit 3's outstanding achievement of 3,000 days of trouble-free operation. The Complex also has a dozen 150 MW combined cycle units burning imported liquefied natural gas for electrical system peaking. 4 photos.

    The architecture of the GTA control system, the nature of a typical GTA commissioning activity, and the varied interests of those analyzing the data make it challenging to develop a general-purpose scheme for archiving data and making the data available to those who will use it. Addressing the needs of those who develop and trouble-shoot hardware and software increases the challenge. This paper describes the aspects of GTA that affect archiving operations and discusses how the features of the EPICS archiving module meet a variety of needs for storing and accessing data.

    Everyone tangles, from time to time, with stress- or depression-causing influences, such as grief or divorce. Usually people can cope with such feelings and recapture a general sense of well-being. At other times, someone may want to seek expert advice and counseling when a problem becomes particularly troubling or long-lasting. In such instances, counseling is a good course of action to take. In fact, delaying or failing to seek assistance may cause feelings of despair or stress to get worse.

    1993-09-01

    The goal of this project is to investigate the conditions in which volatiles will burn within both the dense and freeboard regions of fluidized beds. Experiments using a fluidized bed operated at incipient fluidization will be performed to characterize the effect of particle surface area, initial fuel concentration, and particle type on the inhibition of volatiles within a fluidized bed. The work conducted during the period 4 March, 1993 through 3 June, 1993 is reported in this technical progress report. The work during this time period consists primarily of the startup and trouble shooting of the fluidized bed reactor and gas phase modeling of methane and propane.

    A magnetic sludge is partly produced around the tube sheet outside a steam generator due to stress and heat. The sludge with magnetite is one of the important factors affecting eddy current signals. It causes trouble for the safety of the steam generator tubes and is difficult to detect by conventional eddy current methods. A new type of probe is needed to detect the signals for the magnetic sludge. We designed a new U-type yoke which has two kinds of coils--a magnetizing coil and the other a detecting coil--and we simulated the signal induced by the ferromagnetic sludge in the Inconel 600 tube.

    1993-08-30

    Managing thermal stresses in subsea pipelines carrying heated petroleum requires extensive thermal-stress analysis to predict trouble spots and to ensure a design flexible enough to anticipate stresses and expansions. Explored here are various methods for resolving predicaments posed by thermal loads and resulting deformations by keeping the stresses and deformations in the pipeline system within allowable limits. The problems posed by thermal stresses are not unique; the solutions proposed here are. These methods are based on recent work performed for a major Asian subsea pipeline project currently under construction.

  3. Radioactive and other environmental threats to the United States and the Arctic resulting from past Soviet activities

    SciTech Connect (OSTI)

    1993-12-31

    Earlier this year the Senate Intelligence Committee began to receive reports from environmental and nuclear scientists in Russia detailing the reckless nuclear waste disposal practices, nuclear accidents and the use of nuclear detonations. We found that information disturbing to say the least. Also troubling is the fact that 15 Chernobyl style RBMK nuclear power reactors continue to operate in the former Soviet Union today. These reactors lack a containment structure and they`re designed in such a way that nuclear reaction can actually increase when the reactor overheats. As scientists here at the University of Alaska have documented, polar air masses and prevailing weather patterns provide a pathway for radioactive contaminants from Eastern Europe and Western Russia, where many of these reactors are located. The threats presented by those potential radioactive risks are just a part of a larger Arctic pollution problem. Every day, industrial activities of the former Soviet Union continue to create pollutants. I think we should face up to the reality that in a country struggling for economic survival, environment protection isn`t necessarily the high priority. And that could be very troubling news for the Arctic in the future.

    This Acceptance Test Report for the PUREX Surveillance and Monitoring and Control System (SAMCONS) Uninterruptible Power Supply (UPS) Acceptance Test Procedure validates the operation of the UPS, all alarming and display functions and the ability of the UPS to supply power to the SAMCONS as designed. The proper installation of the PUREX SAMCONS Trailer UPS components and wiring will be systematically evaluated by performance of this procedure. Proper operation of the SAMCONS computer UPS will be verified by performance of a timed functional load test, and verification of associated alarms and trouble indications. This test procedure will be performed in the SAMCONS Trailer and will include verification of receipt of alarms at the SAMCONS computer stations. This test may be performed at any time after the completion of HNF-SD-CP-ATP-083, PUREX Surveillance and Monitoring and Control System (SAMCONS) Acceptance Test Procedure, when computer display and alarm functions have been proven to operate correctly.

  5. Australian liquids-handling system cuts surges to LPG plant

    SciTech Connect (OSTI)

    McKee, G.; Stenner, T.D. )

    1990-08-06

    This paper reports how a pipeline liquids-handling facility recently commissioned allows gas production to be quickly ramped up to meet customer demand. Its design eliminates trouble-some liquid surges which had hampered plant operations. The pipeline-loop system, located at the Wallumbilla LPG processing plant, Queensland, was built for 60 of the cost of an equivalently sized conventional slug catcher. Its control system enables automatic, unattended handling of liquid surges and pigging slugs from the 102-km Silver Springs to Wallumbilla two-phase pipeline. Because of this system's simple hydraulics, normal slug-catcher piping design problems are eliminated. Safety is improved because the potentially hazardous condensate liquid is contained in a buried pipeline.

    Since the beginning of the Year 2001, the Saint-Agnes-Hospital in Bocholt, Germany, operates a phosphoric acid fuel cell (PAFC) to provide the base load of electrical power as well as heat in Winter and air conditioning in Summer. The project was made possible by federal funding from the U.S. Department of Energy as well as by a strategic alliance with the local utility company, the Bocholter Energie- und Wasserversorgung GmbH (BEW), and with the gas supplier of BEW, the Thyssengas GmbH. The fuel cell power plant is combined with an absorption chiller. It is highly efficient and has an excellent power to heat ratio. The operation during the first Year went smoothly and nearly free of trouble.

  7. HANFORD POSITION PAPER ON ACCURACY & CALIBRATION OF 3013 BALANCE & 9975 DRUM SCALE

    SciTech Connect (OSTI)

    PRITCHETT, B.D.

    2007-06-28

    Shipping of materials between different locations requires methods for confirming that the correct quantities and materials are shipped and received intact. The quickest method for confirming the correct quantity of material is to weigh the material on a balance. In order for the shipper's and receiver's balances to agree, the balances must use a traceable method of periodic calibration. Once calibrated, the balances must be rechecked periodically with accepted standards to confirm that the balances remain within the allowable tolerances. This letter affirms that the balances used for weighing 3013 containers and 9975 shipping packages are staying within allowable accepted tolerances and that there is no discernable ''drift'' in the weighings that might indicate future trouble with the balance.

  8. Evaluation of aftermarket LPG conversion kits in light-duty vehicle applications. Final report

    SciTech Connect (OSTI)

    Bass, E.A.

    1993-06-01

    SwRI was contracted by NREL to evaluate three LPG conversion kits on a Chevrolet Lumina. The objective of the project was to measure the Federal Test Procedure (FTP) emissions and fuel economy of these kits, and compare their performance to gasoline-fueled operation and to each other. Varying LPG fuel blends allowed a preliminary look at the potential for fuel system disturbance. The project required kit installation and adjustment according to manufacturer`s instructions. A limited amount of trouble diagnosis was also performed on the fuel systems. A simultaneous contract from the Texas Railroad Commission, in cooperation with NREL, provided funds for additional testing with market fuels (HD5 propane and industry average gasoline) and hydrocarbon (HC) emissions speciation to determine the ozone-forming potential of LPG HC emissions. This report documents the procurement, installation, and testing of these LPG conversion kits.

  9. A proposed interim improvement to the Tevatron beam position monitors with narrow band crystal filters

    SciTech Connect (OSTI)

    Cheng-Yang Tan

    2003-08-25

    Since the start of Run II, we have found that we are unable to reliably and accurately measure the beam position with the present BPM system during high energy physics (HEP). This problem can be traced back to the analogue frontend called the AM/PM module which has trouble handling coalesced beam, but works well with uncoalesced beam. In this paper, we propose a simple fix to the AM/PM module so that we can measure the beam position during HEP. The idea is to use narrow band crystal filters which ring when pinged by coalesced beam so that the AM/PM module is tricked into thinking that it is measuring uncoalesced beam.

  10. Residual Monte Carlo high-order solver for Moment-Based Accelerated Thermal Radiative Transfer equations

    SciTech Connect (OSTI)

    Willert, Jeffrey Park, H.

    2014-11-01

    In this article we explore the possibility of replacing Standard Monte Carlo (SMC) transport sweeps within a Moment-Based Accelerated Thermal Radiative Transfer (TRT) algorithm with a Residual Monte Carlo (RMC) formulation. Previous Moment-Based Accelerated TRT implementations have encountered trouble when stochastic noise from SMC transport sweeps accumulates over several iterations and pollutes the low-order system. With RMC we hope to significantly lower the build-up of statistical error at a much lower cost. First, we display encouraging results for a zero-dimensional test problem. Then, we demonstrate that we can achieve a lower degree of error in two one-dimensional test problems by employing an RMC transport sweep with multiple orders of magnitude fewer particles per sweep. We find that by reformulating the high-order problem, we can compute more accurate solutions at a fraction of the cost.

    Wendt, M.; /Fermilab

    2011-08-01

    Beam position monitoring (BPM) systems are the workhorse of beam diagnostics for almost any kind of charged particle accelerator: linear, circular or transport-lines, operating with leptons, hadrons or heavy ions. BPMs are essential for beam commissioning, accelerator fault analysis and trouble shooting, machine optics, as well as lattice measurements, and finally, for accelerator optimization, in order to achieve the ultimate beam quality. This presentation summarizes the efforts of the beam instrumentation community on recent developments and advances on BPM technologies, i.e. BPM pickup monitors and front-end electronics (analog and digital). Principles, examples, and state-of-the-art status on various BPM techniques, serving hadron and heavy ion machines, sync light synchrotron's, as well as electron linacs for FEL or HEP applications are outlined.

    2008-12-08

    Over the last number of years researchers at ISU have been developing protein based plastics from soybeans, funded by Soy Works Corporation. These materials have been characterized and the processing of these materials into prototype products has been demonstrated. A wide range of net-shape forming processes, including but not limited to extrusion, injection molding and compression molding have been studied. Issues, including technology transfer, re-formulation and product consistency, have been addressed partially during this contract. Also, commercial-scale processing parameters for protein based plastic products were designed, but not yet applicable in the industry. Support in the trouble shooting processing and the manufacturing of protein based plastic products was provided by Iowa State University during the one year contract.

  14. H. R. 4564: a bill to amend the Internal Revenue Code of 1954 to provide a deduction and special net operating loss rules with respect to certain losses on domestic crude oil, to increase tariffs on petroleum and petroleum products, to require the Strategic Petroleum Reserve to be filled with stripper well oil, and to eliminate certain restrictions on the sale of natural gas and on the use of natural gas and oil.

    The Secure Energy Supply Act of 1986 amends the Internal Revenue Code of 1954. Title I provides a deduction and special net operating loss treatment for certain losses on crude oil. Title II increases tariffs on petroleum and petroleum products, the revenues of which will cover authorized refunds. Title III provides that only stripper well oil or oil exchanged for stripper well oil will be used to fill the Strategic Petroleum Reserve. Title IV removes wellhead price controls and repeals Natural Gas Act jurisdiction over certain first sales of natural gas. Later titles repeal certain restrictions on the use of natural gas and petroleum, repeal incremental pricing requirements, and promote flexibility in rescheduling or marking down troubled loans. The bill was referred to the House Committees on Ways and Means, Energy and Commerce, and Banking, Finance, and Urban Affairs.

    Longwall shearer operators have to walk with their machines along the face to mine coal, but some must endure more respirable dust than others. The Bureau of Mines is willing to help any mine having trouble keeping dust levels below the Federal standard of 2.0 mg/m/sup 3/. Recently, Robert A. Jankowski and others at the Bureau of Mines (BoM) completed a survey of twelve US longwall mines. With the cooperation of mine operators and Mine Safety and Health Administration (MSHA) officials, they gathered information on longwall double-drum shearer installations from compliance records. Six of the operations examined were ''clean'' or regularly in compliance with the dust standard, while the other six had great difficulty in complying. Subsequently, BoM conducted an investigation into the reasons for the non-compliance and a search for possible solutions to the problems.

    1984-08-31

    A 12-member commission appointed by the Interior Department could decide to stop or change the Garrison Diversion Unit irrigation project in North Dakota. Under attack since the early 1970s by environmentalists and farmers whose land was disrupted, the project would store and divert water from the Missouri River in a series of canals and reservoirs. The project also ran into trouble with the Canadian government over concerns about pollution from irrigation runoff. Promoted heavily by the Reagan administration as a way to provide irrigation to dry areas and stabilize the economy, the project conflicts with other government payments to farmers to limit production. Little evidence supports the need to supplement municipal water supplies. Controversy over these issues, the value of free drainage to farmers, the impact of fish screens and other environmental impacts underscroes the need to develop a workable plan agreeable to both sides.

    Disparities in utility rates - observably the result of poor supply-side resource planning - have been small before and will be small once again. Retail wheeling`s promise of short-run gains for a few would, ironically, destroy integrated resource processes in place today that guard against a repeat of yesterday`s planning mistakes. The authors argue that retail wheeling is a troubling answer to a mis-diagnosis of yesterday`s problem. They believe that a variety of other policies offer most of the benefits and few of the risks that retail wheeling poses. These include aggressive wholesale competition, judicious pruning of uneconomic capacity, and serious incorporation of environmental risks into utility planning and regulation.

    1988-07-01

    A front-page article in The Wall Street Journal (June 16, 1988) reports on the rising troubles of waste-to-energy projects. The garbage crisis has promoted the construction of 73 waste-to-energy plants around the country, with hundreds more planned at a combined cost of more than $18 billion, writes Bill Richards. Critics profess to feel an eerie sense of deja vu in the trend toward burning. In the 1990s, they say, this could become for municipalities what the nuclear plant building binge was to electric utilities in the 1970s. It plunged many into an economic and environmental swamp in which a few are still mired, their huge cost over-runs unrecoverable from customers, their shareholder dividends shrunken or ended.

    The operations of carbonization facilities for municipal solid waste treatment in Japan were examined. Input waste, system processes, material flows, quality of char and its utilization, fuel and chemical consumption, control of facility emissions, and trouble areas in facility operation were investigated and analyzed. Although carbonization is a technically available thermochemical conversion method for municipal solid waste treatment, problems of energy efficiency and char utilization must be solved for carbonization to be competitive. Possible solutions include (1) optimizing the composition of input waste, treatment scale, organization of unit processes, operational methods, and quality and yield of char on the basis of analysis and feedback of long-term operating data of present operating facilities and (2) securing stable char demands by linking with local industries such as thermal electric power companies, iron manufacturing plants, and cement production plants.

    1985-07-01

    Trash racks are one of the important parts of the mechanical equipment of hydroelectric stations since their breakage causes shutdown of the turbines until they are repaired. Therefore, the provision of trouble-free operation of racks is of importance. The author states that the most vulnerable part of the rack structure is the bars, which can be damaged both from the static load as a result of clogging and from the stresses occurring during vibration of the bars under the effect of the water passing through them. Used for explaining the processes in the case reported here is the Milovich theory, which does not however touch on all the causes and conditions of increase of oscillation amplitude as it is observed in the laboratory.

    This report presents the results of a study of the lessons learned during the design, testing, and operation of gas-cooled reactor coolant circulators. The intent of this study is to identify failure modes and problem areas of the existing circulators so this information can be incorporated into the design of the circulators for the New Production Reactor (NPR)-Modular High-Temperature Gas Cooled Reactor (MHTGR). The information for this study was obtained primarily from open literature and includes data on high-pressure, high-temperature helium test loop circulators as well as the existing gas cooled reactors worldwide. This investigation indicates that trouble free circulator performance can only be expected when the design program includes a comprehensive prototypical test program, with the results of this test program factored into the final circulator design. 43 refs., 7 tabs.

    2012-02-24

    GENI Project: Sandia National Laboratories is working with several commercial and university partners to develop software for market management systems (MMSs) that enable greater use of renewable energy sources throughout the grid. MMSs are used to securely and optimally determine which energy resources should be used to service energy demand across the country. Contributions of electricity to the grid from renewable energy sources such as wind and solar are intermittent, introducing complications for MMSs, which have trouble accommodating the multiple sources of price and supply uncertainties associated with bringing these new types of energy into the grid. Sandia’s software will bring a new, probability-based formulation to account for these uncertainties. By factoring in various probability scenarios for electricity production from renewable energy sources in real time, Sandia’s formula can reduce the risk of inefficient electricity transmission, save ratepayers money, conserve power, and support the future use of renewable energy.

    Internet Protocol version 4 (IPv4) has been a mainstay of the both the Internet and corporate networks for delivering network packets to the desired destination. However, rapid proliferation of network appliances, evolution of corporate networks, and the expanding Internet has begun to stress the limitations of the protocol. Internet Protocol version 6 (IPv6) is the replacement protocol that overcomes the constraints of IPv4. IPv6 deployment in government network backbones has been mandated to occur by 2008. This paper explores the readiness of the Sandia National Laboratories' network backbone to support IPv6, the issues that must be addressed before a deployment begins, and recommends the next steps to take to comply with government mandates. The paper describes a joint, work effort of the Sandia National Laboratories ASC WAN project team and members of the System Analysis & Trouble Resolution and Network System Design & Implementation Departments.

    Pressure maintenance by waterflooding in some reservoirs may be considered essential for satisfactory oil recovery. The main objective of waterflooding is to place water into a rock formation at both the desired rate and pressure with minimal expense and trouble. This objective, however, cannot be achieved unless this water has certain characteristics. The water, therefore, should be treated and conditioned before injection. This study addresses the treatment phases adopted to improve seawater quality before injection, and to control problems associated with untreated seawater. Also discussed are GUPCO'S (Gulf of Suez Petroleum Co.) experience in seawaterfloods, problems encountered, and corrective actions taken to overcome these problems. The chemical treatment programs adopted are presented along with final conclusions and recommendations that can be applied to similar floods in Egypt with (Gulf of Suez) GOS. 47 refs.

    2012-03-14

    The paucity of High mass X-Ray binaries (HMXB) consisting of a neutron star (NS) accretor and Wolf-Rayet (WR) donor has long been at odds with expectations from population synthesis studies indicating that these systems should survive as the evolved offspring of the observed HMXB population. This tension is particularly troubling in light of recent observations uncovering a preponderance of HMXBs containing loosely bound Be donors which would be expected to naturally evolve into WR-HMXBs. Reconciling the unexpectedly large population of Be-HMXBs with the lack of observed WR-HMXB sources thus serves to isolate the dynamics of CE physics from other binary evolution parameters. We find that binary mergers during CE events must be common in order to resolve tension between these observed populations. Furthermore, future observations which better constrain the background population of loosely bound O/B-NS binaries are likely to place significant constraints on the efficiency of CE removal.

    A well documented, publicly available, global data set for surface ocean carbon dioxide (CO2) parameters has been called for by international groups for nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) project was initiated by the international marine carbon science community in 2007 with the aim of providing a comprehensive, publicly available, regularly updated, global data set of marine surface CO2, which had been subject to quality control (QC). SOCAT version 1.5 was made public in September 2011 and holds 6.3 million quality controlled surface CO2 data from the global oceans and coastal seas, spanning four decades (1968 2007). The SOCAT gridded data is the second data product to come from the SOCAT project. Recognizing that some groups may have trouble working with millions of measurements, the SOCAT gridded product was generated to provide a robust regularly spaced fCO2 product with minimal spatial and temporal interpolation which should be easier to work with for many applications. Gridded SOCAT is rich with information that has not been fully explored yet, but also contains biases and limitations that the user needs to recognize and address.

    To evaluate the results of stent placement for obstructive atherosclerotic aortic disease with or without involvement of the common iliac artery. Forty patients had self-expanding stents primarily or after balloon dilatation in the abdominal aorta between January 2005 and May 2011. All patients had trouble walking. Follow-up examinations were performed with clinical visits; these included color Doppler ultrasonography and computed tomographic angiography. Technical, clinical, and hemodynamic success was achieved in all patients. None of the patients underwent reintervention during the follow-up period, which ranged from 3 months to 6 years (median 24 months). Nine complications occurred in six patients. Of the nine complications, four were distal thromboembolisms, which were successfully treated with catheter-directed thrombolysis or anticoagulation therapy. Endovascular treatment of the obstructive aortic disease using self-expanding stents was safe and effective, with high technical success and long-term patency. Thromboembolic complications were high even though direct stenting was considered protective for thromboembolism formation. Particularly for infrarenal aortic stenosis, it can be recommended as the first-line treatment option for patients with obstructive atherosclerotic aortic disease.

    1995-08-01

    This paper describes a potential role for arms control monitoring technology in peace-keeping operations. The basic idea is to utilize monitoring technology developed or suggested for treaty verification (primarily Conventional Forces Europe (CFE), but other treaties as well) to minimize the exposure of humans as part of ``peace-keeping`` forces in various trouble spots throughout the world. The impetus comes from the dangers and high costs of stationing peace-keeping of forces in areas such as Bosnia-Herzegovina. Aside from the costs associated with such efforts the loss of life has escalated recently from 743 peace keepers lost from 1948 to 1988, to 180 lives lost in 1993 alone. Some potential advantages to using technology for certain monitoring roles are discussed in the paper and include: minimizing exposure/risk to peace-keeping personnel from hostile fire, hostage taking, etc.; sharable technology will allow all parties to view results, assess violations or transgressions, etc.; can be applied to equipment, railways, roads, etc., to confirm human and other monitoring capabilities; and provides data to settle disputes on which side initiated hostilities.

    2015-08-27

    A specific feature of RF linacs based on the pulsed traveling wave (TW) mode of operation is that only a portion of the RF energy is used for the beam acceleration. The residual RF energy has to be terminated into an RF load. Higher accelerating gradients require higher RF sources and RF loads, which can stably terminate the residual RF power. RF feeders (from the RF source though the accelerating section to the load) are vacuumed to transmit multi-megawatt high power RF. This overview will outline vacuumed RF loads only. A common method to terminate multi-MW RF power is to use circulated water (or other liquid) as an absorbing medium. A solid dielectric interface (a high quality ceramic) is required to separate vacuum and liquid RF absorber mediums. Using such RF load approaches in TW linacs is troubling because there is a fragile ceramic window barrier and a failure could become catastrophic for linac vacuum and RF systems. Traditional loads comprising of a ceramic disk have limited peak and average power handling capability and are therefore not suitable for high gradient TW linacs. This overview will focus on ''vacuum dry'' or ''all-metal'' loads that do not employ any dielectric interface between vacuum and absorber. The first prototype is an original design of RF loads for the Stanford Two-Mile Accelerator.

    Two of the US Department of Energy's (DOE) nuclear waste management-related goals are to ensure that waste management is not an obstacle to the further development of light-water reactors and the closure of the nuclear fuel cycle and to fulfill its institutional responsibility for providing safe storage and disposal of existing and future nuclear wastes. As part of its approach to achieving these goals, the Office of Remedial Action and Waste Technology of DOE established what is now called the Nuclear Waste Treatment Program (NWTP) at the Pacific Northwest Laboratory during the second half of FY 1982. To support DOE's attainment of its goals, the NWTP is to provide technology necessary for the design and operation of nuclear waste treatment facilities by commercial enterprises as part of a licensed waste management system and problem-specific treatment approaches, waste form and treatment process adaptations, equipment designs, and trouble-shooting assistance, as required to treat existing wastes. This annual report describes progress during FY 1987 towards meeting these two objectives. 24 refs., 59 figs., 24 tabs.

    Domingos, P.

    1996-12-31

    Two of the most popular approaches to induction are instance-based learning (IBL) and rule generation. Their strengths and weaknesses are largely complementary. IBL methods are able to identify small details in the instance space, but have trouble with attributes that are relevant in some parts of the space but not others. Conversely, rule induction methods may overlook small exception regions, but are able to select different attributes in different parts of the instance space. The two methods have been unified in the RISE algorithm. RISE views instances as maximally specific rules, forms more general rules by gradually clustering instances of the same class, and classifies a test example by letting the nearest rule win. This approach potentially combines the advantages of rule induction and IBL, and has indeed been observed to be more accurate than each on a large number of bench-mark datasets. However, it is important to determine if this performance is indeed due to the hypothesized advantages, and to define the situations in which RISE`s bias will and will not be preferable to those of the individual approaches. This abstract reports experiments to this end in artificial domains.

    1996-12-31

    In the past, utility companies that operate coal-fired boilers entered into long-term contracts with their coal suppliers to secure a steady supply of similar fuels for smooth, trouble-free, day-to- day operations. In today`s environment long-term contracts might seem unappealing because utility strategists would rather be free to switch to different coals to lower costs or meet emissions regulations. Coal switching is often an important part of compliance strategies that seek an optimal balance among technology upgrades, bubble-based emissions averages across several boilers, and open-market trading allowances. Although switching is now motivated by SO{sub 2} compliance, a new coal can affect many other operating characteristics, including pulverizer performance, heat rate, stagging and fouling, unburned carbon in ash, NO{sub x} emissions, and certainly cost. In light of the push for tighter NO{sub x} regulations before the turn of the century under Title I of the Clear Air Act Amendments, it is prudent for utilities to factor in the impact of a coal switch on NO{sub x} and unburned carbon emissions into their coal selection decisions.

    The National Synchrotron Light Source II (NSLS-II) is a state of the art 3-GeV third generation light source currently under construction at Brookhaven National Laboratory. The NSLS-II injection system consists of a 200 MeV linac, a 3-GeV booster synchrotron and associated transfer lines. The transfer lines not only provide a means to deliver the beam from one machine to another, they also provide a suite of diagnostics and utilities to measure the properties of the beam to be delivered. In this paper we discuss the suite of diagnostics that will be used to commission the NSLS-II linac and measure the beam properties. The linac to booster transfer line can measure the linac emittance with a three screens measurement or a quadrupole scan. Energy and energy spread are measured in a dispersive section. Total charge and charge uniformity are measured with wall current monitors in the linac and transformers in the transfer line. We show that the performance of the diagnostics in the transfer line will be sufficient to ensure the linac meets its specifications and provides a means of trouble shooting and studying the linac in future operation.

    California oil producers face a loss of production this year because of constraints on pipeline and tanker transportation to Los Angeles area refineries. The potential bottleneck is occurring at a time when Outer Continental Shelf production is near capacity from Chevron Corp.'s Point Arguello project at the same time production is increasing from Exxon Corp.'s nearby Santa Ynex Unit (SYU) expansion. Both megaprojects must compete for pipeline space with onshore crude producers, notably in California's San Joaquin Valley (SJV). Recent development limiting transportation options include: An indefinite shutdown of Four Corners Pipe Line Co.'s 50,000 b/d Line No. 1, damaged by the Jan. 17 earthquake; Loss of a tanker permit by Chevron and partners for offshore Point Arguello production; Permanent shutdown of Exxon's offshore storage and treatment (OST) facility, which since 1981 has used tankers to transport about 20,000 b/d of SYU production from the Santa Barbara Channel to Los Angeles. The OST, the first commercial floating production system in the US -- placed in the Santa Barbara Channel in 1981 after a decade of precedent setting legal and political battles -- was shut down Apr. 4. The paper discusses these production concerns, available options, the OST shutdown, and the troubled history of the OST.

    A cesium-free H{sup ?} ion source driven with a LaB{sub 6} filament is being operated at the Japan Proton Accelerator Research Complex (J-PARC) without any serious trouble since the restoration from the March 2011 earthquake. The H{sup ?} ion current from the ion source is routinely restricted approximately 19 mA for the lifetime of the filament. In order to increase the beam power at the linac beam operation (January to February 2013), the beam current from the ion source was increased to 22 mA. At this operation, the lifetime of the filament was estimated by the reduction in the filament current. According to the steep reduction in the filament current, the break of the filament was predicted. Although the filament has broken after approximately 10 h from the steep current reduction, the beam operation was restarted approximately 8 h later by the preparation for the exchange of new filament. At the study time for the 3 GeV rapid cycling synchrotron (April 2013), the ion source was operated at approximately 30 mA for 8 days. As a part of the beam current upgrade plan for the J-PARC, the front end test stand consisting of the ion source and the radio frequency quadrupole is under preparation. The RF-driven H{sup ?} ion source developed for the J-PARC 2nd stage requirements will be tested at this test stand.

    Synchronization of colliding beams is one of the major issues of an electron-ion collider (EIC) design because of sensitivity of ion revolution frequency to beam energy. A conventional solution for this trouble is insertion of bent chicanes in the arcs space. In our report we consider a method to provide space coincidence of encountering bunches in the crab-crossing orbits Interaction Region (IR) while repetition rates of two beams do not coincide. The method utilizes pair of fast kickers realizing a bypass for the electron bunches as the way to equalize positions of the colliding bunches at the Interaction Point (IP). A dipole-mode warm or SRF cavities fed by the magnetron transmitters are used as fast kickers, allowing a broad-band phase and amplitude control. The proposed scanning synchronization method implies stabilization of luminosity at a maximum via a feedback loop. This synchronization method is evaluated as perspective for the Medium Energy Electron-Ion collider (MEIC) project of JLab with its very high bunch repetition rate.

    In support of closing the nuclear fuel cycle using non-aqueous separations technology, this project aims to develop computational models of electrorefiners based on fundamental chemical and physical processes. Spent driver fuel from Experimental Breeder Reactor-II (EBR-II) is currently being electrorefined in the Fuel Conditioning Facility (FCF) at Idaho National Laboratory (INL). And Korea Atomic Energy Research Institute (KAERI) is developing electrorefining technology for future application to spent fuel treatment and management in the Republic of Korea (ROK). Electrorefining is a critical component of pyroprocessing, a non-aqueous chemical process which separates spent fuel into four streams: (1) uranium metal, (2) U/TRU metal, (3) metallic high-level waste containing cladding hulls and noble metal fission products, and (4) ceramic high-level waste containing sodium and active metal fission products. Having rigorous yet flexible electrorefiner models will facilitate process optimization and assist in trouble-shooting as necessary. To attain such models, INL/UI has focused on approaches to develop a computationally-light and portable two-dimensional (2D) model, while KAERI/SNU has investigated approaches to develop a computationally intensive three-dimensional (3D) model for detailed and fine-tuned simulation.

    The main objective of the Northwest Clean Energy Application Center (NW CEAC) is to promote and support implementation of clean energy technologies. These technologies include combined heat and power (CHP), district energy, waste heat recovery with a primary focus on waste heat to power, and other related clean energy systems such as stationary fuel cell CHP systems. The northwest states include AK, ID, MT, OR, and WA. The key aim/outcome of the Center is to promote and support implementation of clean energy projects. Implemented projects result in a number of benefits including increased energy efficiency, renewable energy development (when using opportunity fuels), reduced carbon emissions, improved facility economics helping to preserve jobs, and reduced criteria pollutants calculated on an output-based emissions basis. Specific objectives performed by the NW CEAC fall within the following five broad promotion and support categories: 1) Center management and planning including database support; 2) Education and Outreach including plan development, website, target market workshops, and education/outreach materials development 3) Identification and provision of screening assessments & feasibility studies as funded by the facility or occasionally further support of Potential High Impact Projects; 4) Project implementation assistance/trouble shooting; and 5) Development of a supportive clean energy policy and initiative/financing framework.

    Amoco Production Co. has used large-diameter coiled tubing strings to avoid damaging gas wells with kill fluids. The coiled tubing is stripped in the gas well under pressure. In Amoco's case, the gas flows up the tubing/casing annulus. The coiled tubing string provides a way to blow down the well whenever the well loads up with liquids from completion, workover, or naturally produced fluids. This paper reports that to date, Amoco has installed coiled tubing in four wells. The oldest has 18 months of service. Although some turbine longevity questions must be answered, the first four completions have proven fast and trouble free. The basic equipment for handling coil tubing is shown. The transport trailer and tubing injector head are similar to standard servicing equipment and not considered experimental. The production tubing reel is capable of carrying 14,000 ft of 2-in tubing or 18,000 ft of 1 3/4-in. tubing. For shallower wells, multiple tubing strings can be would on the same spool. Because of handling difficulties of large tubing, spools must be wound at the factory. Most of the largest sizes are made to order, making lead time a necessary consideration.

    Face haulage equipment used in conjunction with continuous miners (shuttle cars, diesel haulers, battery scoops, and bridge conveyors) was investigated by recording section delay reports for computer analysis to determine the effect of haulage equipment failures and downtime on productivity, pinpoint the causes of machine failures and downtime, and develop the possible design and operational changes required to reduce machine failures and downtime and increase section productivity. For the mobile vehicle type of haulage (shuttle car, diesel hauler, and battery scoop) failure of one unit in multiple unit haulage operations would not normally stop section production. Bridge conveyors as a haulage system provide continuous haulage of section production but when any part of the bridge system fails, the section production is stopped. In the course of this program, it was determined through the use of daily section shift reports on 200 machines that face haulage equipment is responsible for about 40 to 56 minutes of lost section production time per shift. The most prevalent failure for shuttle cars was found to be the trailing cable umbilical. Bridge conveyors had the most trouble with the conveyor subsystem. Discussions of these and other recorded failures are developed with possible solutions outlined for future implementation. This report only covers the face haulage element of the continuous miner system. Companion reports were developed for the continuous miner and roof bolter elements under separate task orders.

    Arrangements might be created for siting nuclear installations on land ceded by a host State for administration by an international or multinational organization. Such arrangements might prove useful in terms of resolving suspicions of proliferation in troubled areas of the world, or as a means to introduce nuclear activities into areas where political, financial or technical capabilities might otherwise make such activities unsound, or as a means to enable global solutions to be instituted for major nuclear concerns (e.g., spent fuel management). The paper examines practical matters associated with the legal and programmatic aspects of siting nuclear installations, including diplomatic/political frameworks, engaging competent industrial bodies, protection against seizure, regulation to ensure safety and security, waste management, and conditions related to the dissolution of the extra-territorial provisions as may be agreed as the host State(s) achieve the capabilities to own and operate the installations. The paper considers the potential for using such a mechanism across the spectrum of nuclear power activities, from mining to geological repositories for nuclear waste. The paper considers the non-proliferation dimensions associated with such arrangements, and the pros and cons affecting potential host States, technology vendor States, regional neighbors and the international community. It considers in brief potential applications in several locations today.

    The CAPER facility of the Tritium Laboratory Karlsruhe has demonstrated the technology for the tokamak exhaust processing. CAPER has been significantly upgraded to pursue research/development programs towards highly tritiated water (HTW) handling and processing. The preliminary tests using a metal oxide reactor producing HTW afterward de-tritiated with PERMCAT were successful. In a later stage, a micro-channel catalytic reactor was installed in view of long term research program on HTW. The integration of this new system in CAPER was carried out along with a careful safety analysis due to high risk associated with such experiments. First experiments using the μ-CCR were performed trouble free, and HTW up to 360 kCi/kg was produced at a rate of 0.5 g/h. Such HTW was collected into a platinum zeolite bed (2 g of HTW for 20 g of Pt-zeolite), and in-situ detritiation was performed via isotopic exchange with deuterium. These first experimental results with tritium confirmed the potential for the capture and exchange method to be used for HTW in ITER. (authors)

    The behavior of nuclear fuel in the reactor environment is affected by multiple physics, most notably heat conduction and solid mechanics, which can have a strong influence on each other. To provide credible solutions, a fuel performance simulation code must have the ability to obtain solutions for each of the physics, including coupling between them. Solution strategies for solving systems of coupled equations can be categorized as loosely-coupled, where the individual physics are solved separately, keeping the solutions for the other physics fixed at each iteration, or tightly coupled, where the nonlinear solver simultaneously drives down the residual for each physics, taking into account the coupling between the physics in each nonlinear iteration. In this paper, we compare the performance of loosely and tightly coupled solution algorithms for thermomechanical problems involving coupled thermal and mechanical contact, which is a primary source of interdependence between thermal and mechanical solutions in fuel performance models. The results indicate that loosely-coupled simulations require significantly more nonlinear iterations, and may lead to convergence trouble when the thermal conductivity of the gap is too small. We also apply the tightly coupled solution strategy to a nuclear fuel simulation of an experiment in a test reactor. Studying the results from these simulations indicates that perhaps convergence for either approach may be problem dependent, i.e., there may be problems for which a loose coupled approach converges, where tightly coupled wont converge and vice versa.

    The comprehensive planning required for a well drilled on a national seashore resulted in a trouble-free operation that minimized effects on a very sensitive environmental area. The procedure for obtaining approval from the National Park Service for this exploration well was very detailed and time consuming. Bright and Co., San Antonio, drilled the Dunn-McCampbell No. 1 on the Padre Island National Seashore in Kleberg County in South Texas earlier this year. Although the federal government owns all surface lands in the National Seashore, the majority of the subsurface oil and gas rights are owned by the Dunn-McCampbell heirs. Development of the private oil and gas rights may occur in the National Seashore area as long as operators comply with National Park Service regulations of Title 36, Code of federal Regulations Part 9, Subpart B. Precautions to contain and collect any discharge of liquids were required because Padre Island has a shallow freshwater aquifer approximately 4 ft below the ground surface. The water from the aquifer collects in shallow ponds on the island and is the main source of drinking water for wildlife there. Therefore, the National Park Service requires groundwater monitoring wells at the production facility site to determine if any contaminants enter the groundwater.

    Patch-based structured adaptive mesh refinement (SAMR) is widely used for high-resolution simu- lations. Combined with modern supercomputers, it could provide simulations of unprecedented size and resolution. A persistent challenge for this com- bination has been managing dynamically adaptive meshes on more and more MPI tasks. The dis- tributed mesh management scheme in SAMRAI has made some progress SAMR scalability, but early al- gorithms still had trouble scaling past the regime of 105 MPI tasks. This work provides two critical SAMR regridding algorithms, which are integrated into that scheme to ensure efficiency of the whole. The clustering algorithm is an extensionmore » of the tile- clustering approach, making it more flexible and efficient in both clustering and parallelism. The partitioner is a new algorithm designed to prevent the network congestion experienced by its prede- cessor.

    Despite growth in revenues during 1979, electric utilities are greatly troubled by high inflation, restricted capital, and the lack of rate relief from utility commissions. The growth, although smaller than normal, will likely convince commissions to respond to rate increase requests by authorizing only the smallest possible increases. With inflationary pressures eroding utility companies' financial base, the benefits of rate increases are wiped out after a year or so, necessitating a return to the commissions for futher adjustments. This up-down cycling is reflected in the report of the performances of the top one hundred utility companies. Earning growth statistics, sales data, financial statistics, and company performances (electric sales, customers served, revenues, and after-tax net income) of top one hundred electric utilities are given in separate tables for 1979. Overall, kWh sales were up 2.9%; revenues were up 13.4%; net income was up 8.1%; and overall earnings performance was a weak increase of 9.4%. (SAC)

    Internet Protocol version 4 (IPv4) has been a mainstay of the both the Internet and corporate networks for delivering network packets to the desired destination. However, rapid proliferation of network appliances, evolution of corporate networks, and the expanding Internet has begun to stress the limitations of the protocol. Internet Protocol version 6 (IPv6) is the replacement protocol that overcomes the constraints of IPv4. As the emerging Internet network protocol, SNL needs to prepare for its eventual deployment in international, national, customer, and local networks. Additionally, the United States Office of Management and Budget has mandated that IPv6 deployment in government network backbones occurs by 2008. This paper explores the readiness of the Sandia National Laboratories network backbone to support IPv6, the issues that must be addressed before a deployment begins, and recommends the next steps to take to comply with government mandates. The paper describes a joint work effort of the Sandia National Laboratories ASC WAN project team and members of the System Analysis & Trouble Resolution, the Communication & Network Systems, and Network System Design & Implementation Departments.

    Two areas of medium and high voltage protective relaying for industry applications are addressed: (1) generator backup protection and (2) protection of transformers with relatively high values of available fault currents. The presentation is a series of cases that were studied on electrical power systems at different industry facilities. The first part of this paper discusses the use of voltage controlled or voltage restraint time-overcurrent (51V) relays and distance (21) relays applied as generator backup protection. Actual applications on bus-connected and unit-connected generators are presented with a discussion of the protective relay settings and problems encountered. The second part of this paper discusses the application of proper protective devices, including protective relays and instrument transformers to protect transformers installed on buses with relatively high available primary fault currents. Problems encountered with the instrument transformer and protective relay selection are addressed, including saturation, burden, and protection from failure. Emphasis is placed on routine and special applications, lessons learned on real projects, and trouble spots to avoid.

    The 1994 Nuclear Industry Conference, held in London United Kingdom, September 14--15, 1994, was the first serious nuclear energy conference to take place for more than 12 years. It had a challenging agenda, no less than whether the industry would sustain its role into the twenty-fist century. The conference focused on the world`s nuclear industry, which is in a crucial period of development, with few new reactors being built in Western Europe and none in the US. Attention in the industry is moving eastward to the troubled legacy of eastern Europe and to the dynamic new markets of the Far East. The immediate future of the reactor builders lies in these regions, for without new orders, the industry will decline. At the same time, the industry faces challenges at home. The end of the Cold War has brought a new appraisal of the fuel cycle, the ever-present dangers of proliferation, and the problems of long-term waste-disposal and decommissioning remain. New challenges include the role for nuclear energy as privatization of power utilities and liberalization of electricity markets takes place. Whether short-term market trends will dominate new orders for power plants or whether supply security considerations count was also discussed.

  14. Low mass dark matter and invisible Higgs width in darkon models

    The Standard Model (SM) plus a real gauge-singlet scalar field dubbed darkon (SM+D) is the simplest model possessing a weakly interacting massive particle (WIMP) dark matter candidate. In this model, the parameters are constrained from dark matter relic density and direct searches. The fact that interaction between darkon and SM particles is only mediated by a Higgs boson exchange may lead to significant modifications to the Higgs boson properties. If the dark matter mass is smaller than half of the Higgs boson mass, then a Higgs boson can decay into a pair of darkons resulting in a large invisible branching ratio. The Higgs boson will be searched for at the LHC and may well be discovered in the near future. If a Higgs boson with a small invisible decay width will be found, the SM+D model with small dark matter mass will be in trouble. We find that by extending the SM+D to a two Higgs doublet model plus a darkon (THDM+D) it is possible to have a Higgs boson with a small invisible branching ratio and at the same time the dark matter can have a low mass. We also comment on other implications of this model.

    A 24-year-old oil well tester was rendered semiconscious by hydrogen sulfide (H2S). He received oxygen and was hospitalized but released in 30 minutes. The next day, nausea, vomiting, diarrhea, and incontinence of urine and stool led to rehospitalization. These problems and leg shaking, dizziness, sweating, trouble sleeping, and nightmares prevented his return to work. A physical examination, chest x-ray, and pulmonary function tests were normal 39 months after the episode but vibration sense was diminished. Two choice visual reaction times were delayed. Balance was highly abnormal (5 to 6 cm/sec) with eyes closed. Blink reflex latency was slow (R-1 17.5 msec versus normal 14.3 msec). Numbers written on finger tips were not recognized. Verbal and visual recall were impaired but overlearned memory was intact. Cognitive functions measured by Culture Fair, block design, and digit symbol were impaired. Perceptual motor was slow. Scores for confusion, tension-anxiety, depression, and fatigue were elevated and vigor was reduced. Forty-nine months after exposure his reaction time, sway speed, and color vision had not improved. His recall and his cognitive, constructional, and psychomotor speeds had improved but remained abnormal. These deficits are most likely due to H2S. Similar testing of other survivors is recommended.

    The FILL component in TRAC-P defines a phasic-velocities boundary condition or total-mass-flow boundary condition. FILL option IFTY = 10 defines the total-mass flow and its composition for flow donoring from the FILL to its adjacent component by signal variables and/or control blocks. For flow from the adjacent component to the FILL component, the phasic densities of the adjacent-component cell need to be upstream donored by the IFTY = 10 option total-mass flow. Instead, the FILL-cell phasic densities are being downstream donored incorrectly by the IFTY = 10 option total-mass flow in determining the FILL-junction phasic velocities. Using the wrong donored phasic densities caused the phasic velocities determined from the total-mass flow to be evaluated incorrectly. Five errors related to phasic-density donoring into a FILL- or BREAK-component cell are corrected by update FXFILL. Seven versions of a new test problem test these corrections and show that the errors of trouble reports 189 and 190 no longer exist in TRAC-P.

    The paucity of High mass X-Ray binaries (HMXB) consisting of a neutron star (NS) accretor and Wolf-Rayet (WR) donor has long been at odds with expectations from population synthesis studies indicating that these systems should survive as the evolved offspring of the observed HMXB population. This tension is particularly troubling in light of recent observations uncovering a preponderance of HMXBs containing loosely bound Be donors which would be expected to naturally evolve into WR-HMXBs. Reconciling the unexpectedly large population of Be-HMXBs with the lack of observed WR-HMXB sources thus serves to isolate the dynamics of CE physics from other binarymoreevolution parameters. We find that binary mergers during CE events must be common in order to resolve tension between these observed populations. Furthermore, future observations which better constrain the background population of loosely bound O/B-NS binaries are likely to place significant constraints on the efficiency of CE removal.less

    The 500-keV negative-ion based neutral beam injector for JT-60U started operation in 1996. The beam power has been increased gradually through optimizing operation parameters of the ion sources and conquering many troubles in the ion source and power supplies caused by a high voltage break-down in the accelerator. However, some issues remain to be solved concerning the ion source for increasing further the beam power and the beam energy. The most serious issue of them is non-uniformity of source plasma in the arc chamber. Various countermeasures have been implemented to improve the non-uniformity. Some of those countermeasures have been found to be partially effective in reducing the non-uniformity of the source plasma, and as the result the ion source, so far, has accelerated negative-ion beams of 17.4A at 403keV with deuterium and 20A at 360keV with hydrogen against the goal of 22A at 500keV. The neutral beam injection power into the plasma has reached 5.8MW at 400keV with deuterium. Further efforts to reach the target of 10MW at 500keV have been continued.

  19. Biofuels Fuels Technology Pathway Options for Advanced Drop-in Biofuels Production

    2011-09-01

    Advanced drop-in hydrocarbon biofuels require biofuel alternatives for refinery products other than gasoline. Candidate biofuels must have performance characteristics equivalent to conventional petroleum-based fuels. The technology pathways for biofuel alternatives also must be plausible, sustainable (e.g., positive energy balance, environmentally benign, etc.), and demonstrate a reasonable pathway to economic viability and end-user affordability. Viable biofuels technology pathways must address feedstock production and environmental issues through to the fuel or chemical end products. Potential end products include compatible replacement fuel products (e.g., gasoline, diesel, and JP8 and JP5 jet fuel) and other petroleum products or chemicals typically produced from a barrel of crude. Considering the complexity and technology diversity of a complete biofuels supply chain, no single entity or technology provider is capable of addressing in depth all aspects of any given pathway; however, all the necessary expert entities exist. As such, we propose the assembly of a team capable of conducting an in-depth technology pathway options analysis (including sustainability indicators and complete LCA) to identify and define the domestic biofuel pathways for a Green Fleet. This team is not only capable of conducting in-depth analyses on technology pathways, but collectively they are able to trouble shoot and/or engineer solutions that would give industrial technology providers the highest potential for success. Such a team would provide the greatest possible down-side protection for high-risk advanced drop-in biofuels procurement(s).

    In the context of retail electric competition, various mechanisms have been proposed to address threats to low-income energy affordability. Most proposals include the use of ratepayer for (a) low-income bill payment support (e.g., rate discounts) and/or (b) energy efficiency programs specifically designated for low-income customers. An integrated approach to both energy efficiency and low-income bill payment is being tested in New Jersey. The program specifically targets payment-troubled customers and those with the lowest incomes. It combines a three-part approach to energy affordability: (1) deep and comprehensive gas and electric efficiency measures; (2) extensive customer energy education, with the goals of both (a) empowering participants with the skills and knowledge to gain control of their energy situation and (b) securing action commitment that the customer carries out as a partner to save energy and lower their utility bills; and (3) an affordable payment plan which includes extended payment of arrearages, partial arrearage forgiveness, and a bill discount for those in the lowest income tier who maintain their partnership obligations. This paper describes the E-Team Partners program design, presents preliminary impact evaluation results for the first 7,000 participants, and discusses the attributes of this model in a restructured environment.

    Interest appears to be at an all-time high for riparian conservation programs in Gilliam County. With the recently added Herbaceous Buffer and the already established CREP program interest is booming. However, more and more people are turning towards the herbaceous buffer because of expense. The riparian forest buffer is becoming too expensive. Even with the excellent cost share and incentives landowners are having trouble with Farm Service Agency's payment limitation. Because of this payment limitation landowners are not receiving their full rental and incentive payments, usually in year one. This has cooled the installation of riparian forest buffers and peaked interest in the CP-29 (Herbaceous Buffer for Wildlife). Either way, riparian lands are being enhanced and water quality is being improved. Year three should be very similar to the accomplishments of year 2. There has already been several projects proposed that may or may not be approved during year 3. I am currently working on three projects that are all over 2.5 miles long on each side and total anywhere from 60 to 250 acres in size. Along with these three projects there at least seven small projects being proposed. Four of those projects are riparian forest buffers and the remaining are herbaceous buffers.

    The meltdown of the Cold War was a shock to the systems built to cope with it. At the DOE`s Hanford Site in Washington State, a world-class safeguards and security system was suddenly out of step with the times. The level of protection for nuclear and classified materials was exceptional. But the cost was high and the defense facilities that funded security were closing down. The defense mission had created an umbrella of security over the sprawling Hanford Site. Helicopters designed to ferry special response teams to any trouble spot on the 1,456 square-kilometer site made the umbrella analogy almost literally true. Facilities were grouped into areas, fenced off like a military base, and entrance required a badge check for everyone. Within the fence, additional rings of protection were set up around security interests or targets. The security was effective, but costly to operate and inconvenient for employees and visitors alike. Moreover, the umbrella meant that virtually all employees needed a security clearance just to get to work, whether they worked on classified or unclassified projects. Clearly, some fundamental rethinking of safeguards and security was needed. The effort to meet that challenge is the story of transition at Hanford and documented here.

    1994-12-01

    Significant quantities of hydrocarbon reserves are contained in North Sea high-temperature, high-pressure (HTHP) reservoirs. Development of these reserves will require deviated wells. This paper outlines the planning, drilling, and testing of the first deviated HTHP well in the UK Sector of the North Sea. The high temperature requires mud systems, downhole equipment, and tools designed to work at elevated temperatures. The convergence of pore and fracture pressures leads to problems owing to the narrow band of mud weight between inducing losses and inducing a kick. This aspect of these wells probably causes the most trouble. The high mud weights required for well control leads to a situation where, owing to the large difference between formation-fluid and mud pressure gradients, mud overbalance becomes so high at the bottom of long permeable hole sections that differential sticking becomes likely. These problems are magnified when drilling small-diameter directional holes. The most important single factor in controlling these problems is the mud system design.

    A traditional view of incidents is that they are caused by shortcomings in human competence, attention, or attitude. It may be under the label of “loss of situational awareness,” procedure “violation,” or “poor” management. A different view is that human error is not the cause of failure, but a symptom of failure – trouble deeper inside the system. In this perspective, human error is not the conclusion, but rather the starting point of investigations. During an investigation, three types of information are gathered: physical, documentary, and human (recall/experience). Through the causal analysis process, apparent cause or apparent causes are identifiedmore » as the most probable cause or causes of an incident or condition that management has the control to fix and for which effective recommendations for corrective actions can be generated. A causal analysis identifies relevant human performance factors. In the following presentation, the anatomy of a radiological incident is discussed, and one case study is presented. We analyzed the contributing factors that caused a radiological incident. When underlying conditions, decisions, actions, and inactions that contribute to the incident are identified. This includes weaknesses that may warrant improvements that tolerate error. Measures that reduce consequences or likelihood of recurrence are discussed.« less

    My first encounter with a quality assurance auditor is reminiscent of an old Dodge commercial. You remember? The old sheriff, masked in mirrored sunglasses, paunch hanging over his gun belt, prophesying, ``You`re in a heap o` trouble boy!`` Well, my auditor could have been kin to the sheriff; they had the same posture, attitude, and mirrored sunglasses. Plus, my auditor wore a black leather vest and sported a ``Buffalo Bill`` goatee. While certainly memorable, both gentlemen were far from pleasant. I`m fairly certain that the compliance auditor of old deserved this perceived association with his law enforcement counterpart. Both believed in enforcing the letter of the law, or their interpretations of it.

  8. Control design deficiencies in HUD solar demonstration projects

    1985-01-01

    The Department of Housing and Urban Devlopment (HUD) residential solar heating and cooling demonstration program provided funding support for over 600 solar projects. These projects provide the largest single data base of solar heating and cooling experience now available. These data suggest that controls were problematic in many of the active and passive heating and domestic and domestic hot water systems in the program. This paper will assess the active system modes of operation and the control components as to their ability to perform as intended. A large number of systems in the demonstration program experienced control problems during testing, checkout, and operation (there were 238 reported control problems involving 192 systems). Frequently, trouble-shooting site visitors found control problems had disabled the whole system or caused a portion of the system to malfunction. The consequences are not as significant on the more carefully designed systems (i.e., the auxiliary still functions) but, on systems with inappropriately designed solar-auxiliary interfaces, the homeowners often were without adequate heat. The most common control problems involved excessive modes in system and, therefore, control design; errors in sensor set points, location, or installation; and poorly engineered or installed wiring to and from controller panels.

  9. Ionized cluster beam technology for material science

    The most suitable kinetic energy range of ionized materials in film formation and epitaxial growth is from a few eV to a few hundreds eV, especially, less than about 100eV, when ions are used as a host. The main roles of ions in film formation are the effects due to their kinetic energy and the electronic charge effects which involve the effect to active film formation and the effect acceleration of chemical reactions. Therefore, it is important to develope the technology to transport large volume of a flux of ionized particles with an extremely low incident energy without any troubles due to the space charge effects and charge up problems on the surface. This is the exact motivation for us to have been developing the Ionized Cluster Beam (ICB) technology since 1972. By ICB technology materials (actually wide varieties of materials such as metal, semiconductor, magnetic material, insulator, organic material, etc.) are vaporized and ejected through a small hole nozzle into a high vacuum, where the vaporized material condenses into clusters with loosely coupled atoms with the sizes about from 100 to a few 1000 atoms (mainly 100-2000 atoms) by supercondensation phenomena due to the adiabatic expansion in this evaporation process through a small hole nozzle. In the ICB technology an atom in each cluster is ionized by irradiated by electron shower, and the ionized clusters are accelerated by electric field onto a substrate. The ionized clusters with neutral clusters impinged onto a substrate are spreaded separately into atoms migrating over the substrate, so that the surface migration energy of the impinged atoms, that is, surface diffusion energy are controlled by an incident energy of a cluster. In this report the theoretical and also experimental results of ICB technology are summarized.

  10. A primer on incentive regulation for electric utilities

    SciTech Connect (OSTI)

    Hill, L.J.

    1995-10-01

    In contemplating a regulatory approach, the challenge for regulators is to develop a model that provides incentives for utilities to engage in socially desirable behavior. In this primer, we provide guidance on this process by discussing (1) various models of economic regulation, (2) problems implementing these models, and (3) the types of incentives that various models of regulation provide electric utilities. We address five regulatory models in depth. They include cost-of-service regulation in which prudently incurred costs are reflected dollar-for-dollar in rates and four performance-based models: (1) price-cap regulation, in which ceilings are placed on the average price that a utility can charge its customers; (2) revenue-cap regulation, in which a ceiling is placed on revenues; (3) rate-of-return bandwidth regulation, in which a utility`s rates are adjusted if earnings fall outside a {open_quotes}band{close_quotes} around equity returns; and (4) targeted incentives, in which a utility is given incentives to improve specific components of its operations. The primary difference between cost-of-service and performance-based approaches is the latter sever the tie between costs and prices. A sixth, {open_quotes}mixed approach{close_quotes} combines two or more of the five basic ones. In the recent past, a common mixed approach has been to combine targeted incentives with cost-of-service regulation. A common example is utilities that are subject to cost-of-service regulation are given added incentives to increase the efficiency of troubled electric-generating units.

  11. Risks of LNG and LPG. [Review

    Since the use of liquefied natural gas (LNG) and liquefied petroleum gases (LPG) as fuels is likely to increase and will certainly persist for some time to come, assessment of the safety of LNG/LPG systems will continue to draw attention and is quite likely to force continuing review of operating and design standards for LNG/LPG facilities. Scientific investigations to date appear to have identified the major hazards. Except for the dispersive behavior of vapor clouds - a not-insignificant factor in risk evaluation - the consequences of spills are well circumscribed by current analyses. The physically significant effects accompanying nonexplosive combustion of spilled material are fairly well documented; yet, potentially substantial uncertainties remain. Catastrophic spills of 10/sup 4/-10/sup 5/ m/sup 3/ on land or water are possible, given the current size of storage vessels. Almost all experimental spills have used less than 10 m/sup 3/ of liquid. There is thus some uncertainty regarding the accuracy and validity of extrapolation of current empirical information and physical models to spills of catastrophic size. The less-likely but still-possible explosive or fireball combustion modes are not well understood in respect to their inception. The troubling experience with such violent combustion of similar combustible vapors suggests that this possibility will need further definition. Extant LNG and LPG risk analyses illustrate the difficulties of substantiating the numerous event probabilities and the determination of all event sequences that can lead to hazardous consequences. Their disparate results show that significant improvements are needed. Most importantly, a detailed critique of past efforts and a determination of an exhaustive set of criteria for evaluating the adequacy of a risk analysis should precede any further attempts to improve on existing studies. 44 references, 1 table.

  12. Reliability Estimates for Power Supplies

    2005-09-01

    Failure rates for large power supplies at a fusion facility are critical knowledge needed to estimate availability of the facility or to set priorties for repairs and spare components. A study of the "failure to operate on demand" and "failure to continue to operate" failure rates has been performed for the large power supplies at DIII-D, which provide power to the magnet coils, the neutral beam injectors, the electron cyclotron heating systems, and the fast wave systems. When one of the power supplies fails to operate, the research program has to be either temporarily changed or halted. If one of the power supplies for the toroidal or ohmic heating coils fails, the operations have to be suspended or the research is continued at de-rated parameters until a repair is completed. If one of the power supplies used in the auxiliary plasma heating systems fails the research is often temporarily changed until a repair is completed. The power supplies are operated remotely and repairs are only performed when the power supplies are off line, so that failure of a power supply does not cause any risk to personnel. The DIII-D Trouble Report database was used to determine the number of power supply faults (over 1,700 reports), and tokamak annual operations data supplied the number of shots, operating times, and power supply usage for the DIII-D operating campaigns between mid-1987 and 2004. Where possible, these power supply failure rates from DIII-D will be compared to similar work that has been performed for the Joint European Torus equipment. These independent data sets support validation of the fusion-specific failure rate values.

  13. Grout pump selection process for the Transportable Grout Facility

    McCarthy, D.; Treat, R.L.

    1985-01-01

    Selected low-level radioactive liquid wastes at Hanford will be disposed by grouting. Grout is formed by mixing the liquid wastes with solid materials, including Portland cement, fly ash, and clay. The mixed grouts will be pumped to disposal sites (e.g., trenches and buried structures) where the grout will be allowed to harden and, thereby, immobilize the wastes. A Transportable Grout Facility (TGF) will be constructed and operated by Rockwell Hanford Operations to perform the grouting function. A critical component of the TGF is the grout pump. A preliminary review of pumping requirements identified reciprocating pumps and progressive cavity pumps as the two classes of pumps best suited for the application. The advantages and disadvantages of specific types of pumps within these two classes were subsequently investigated. As a result of this study, the single-screw, rotary positive displacement pump was identified as the best choice for the TGF application. This pump has a simple design, is easy to operate, is rugged, and is suitable for a radioactive environment. It produces a steady, uniform flow that simplifies suction and discharge piping requirements. This pump will likely require less maintenance than reciprocating pumps and can be disassembled rapidly and decontaminated easily. If the TGF should eventually require discharge pressures in excess of 500 psi, a double-acting duplex piston pump is recommended because it can operate at low speed, with only moderate flow rate fluctuations. However, the check valves, stuffing box, piston, suction, and discharge piping must be designed carefully to allow trouble-free operations.

    Solar hot water (SHW) systems have been installed commercially for over 30 years, yet few quantitative details are known about their reliability. This report describes a comprehensive analysis of all of the known major previous research and data regarding the reliability of SHW systems and components. Some important conclusions emerged. First, based on a detailed inspection of ten-year-old systems in Florida, about half of active systems can be expected to fail within a ten-year period. Second, valves were identified as the probable cause of a majority of active SHW failures. Third, passive integral and thermosiphon SHW systems have much lower failure rates than active ones, probably due to their simple design that employs few mechanical parts. Fourth, it is probable that the existing data about reliability do not reveal the full extent of fielded system failures because most of the data were based on trouble calls. Often an SHW system owner is not aware of a failure because the backup system silently continues to produce hot water. Thus, a repair event may not be generated in a timely manner, if at all. This final report for the project provides all of the pertinent details about this study, including the source of the data, the techniques to assure their quality before analysis, the organization of the data into perhaps the most comprehensive reliability database in existence, a detailed statistical analysis, and a list of recommendations for additional critical work. Important recommendations include the inclusion of an alarm on SHW systems to identify a failed system, the need for a scientifically designed study to collect high-quality reliability data that will lead to design improvements and lower costs, and accelerated testing of components that are identified as highly problematic.

    Liberal economic and political reforms in Latin America, a declining oil market in the US, and world events such as last year's Persian Gulf Crisis are making foreign investment in Latin America's energy sector increasingly attractive. The Persian Gulf crisis indicated the US must diversify oil sources; increased competition and deregulation in electric power generation and gas production are providing more opportunities for independent power producers at home and abroad; and Latin America's need for foreign financial and technical assistance are providing an important pull'' factor. Electricity needs in the developing world wig be huge in the years to come. In Latin America and the Caribbean, 66,500 mg of new capacity will be required by 1999. The developing world will require US $100 billion in energy investment a year. But Latin American countries will have trouble obtaining funds. The region will need to rely heavily on private international sources to finance future energy requirements. Multilateral development bank participation win remain critical, however, serving as a catalyst for government reform and private investment in the sector. In particular, World Bank lending will be focused on countries with a clear commitment to pricing reform, regulatory reform, competitive markets, non-market barriers, and technology transfer. Opportunities for foreign participation in the Latin American oil sector are particularly large in Ecuador, Peru, Argentina, and Venezuela. Mexico's plans for reform in the oil sector, a delicate issue in that country, appear to be less defined and likely to occur farther into the future. The conference made clear that a regulatory entity is needed even when the sector is owned by the government. Regulatory processes must be fair and transparent in order to ensure adequate financial and technical performance.

  17. SAFETY AT FLUOR HANFORD (A) CASE STUDY - PREPARED BY THUNDERBIRD SCHOOL OF GLOBAL MANAGEMENT

    By November of 1997, Fluor Hanford (Fluor) had been the site manager of the Hanford nuclear reservation for a year. The Hanford site had been established as part of the Manhattan Project in the 1940s that gave birth to the atomic bomb. Hanford produced two thirds of U.S. plutonium during the Cold War period. The Hanford site was half the size of Rhode Island and occupied 586 square miles in southeastern Washington State. The production of plutonium for more than 40 years left a huge legacy of chemical and radiological contamination: 80 square miles of contaminated groundwater; 2,300 tons of spent nuclear fuel stored in underwater basins; 20 tons of plutonium-laced contaminated materials; and 500 contaminated facilities. The cleanup involved a challenging combination of radioactive material handling within an infrastructure constructed in the 1940s and 1950s. The cleanup that began in 1988 was expected to take 30 years or more. Improving safety at Hanford had already proven to be a significant challenge. As the new site manager at Hanford, Fluor Hanford inherited lower- and mid-level managers and thousands of unionized employees, many of whom were second or third generation Hanford employees. These employees had seen many contractors come and go over the years. Some of the managers who had worked with the previous contractor saw Fluor's emphasis on safety as getting in the way of operations. Union-management relations were fractious. Hanford's culture was described as 'production driven-management told everyone what to do, and, if you didn't do it, there were consequences'. Worker involvement in designing and implementing safety programs was negligible. Fluor Hanford also was having trouble satisfying its client, the Department of Energy (DOE). The DOE did not see a clear path forward for performance improvements at Hanford. Clearly, major change was necessary, but how and where should it be implemented?

    This project provides critical innovations and fundamental understandings that enable development of an economically-viable process for catalytic conversion of biomass (sugar) to 5-hydroxymethylfurfural (HMF). A low-cost ionic liquid (Cyphos 106) is discovered for fast conversion of fructose into HMF under moderate reaction conditions without any catalyst. HMF yield from fructose is almost 100% on the carbon molar basis. Adsorbent materials and adsorption process are invented and demonstrated for separation of 99% pure HMF product and recovery of the ionic liquid from the reaction mixtures. The adsorbent material appears very stable in repeated adsorption/regeneration cycles. Novel membrane-coated adsorbent particles are made and demonstrated to achieve excellent adsorption separation performances at low pressure drops. This is very important for a practical adsorption process because ionic liquids are known of high viscosity. Nearly 100% conversion (or dissolution) of cellulose in the catalytic ionic liquid into small molecules was observed. It is promising to produce HMF, sugars and other fermentable species directly from cellulose feedstock. However, several gaps were identified and could not be resolved in this project. Reaction and separation tests at larger scales are needed to minimize impacts of incidental errors on the mass balance and to show 99.9% ionic liquid recovery. The cellulose reaction tests were troubled with poor reproducibility. Further studies on cellulose conversion in ionic liquids under better controlled conditions are necessary to delineate reaction products, dissolution kinetics, effects of mass and heat transfer in the reactor on conversion, and separation of final reaction mixtures.

    The University of Minnesota aquifer thermal energy storage (ATES) system has been operated as a field test facility (FTF) since 1982. The objectives were to design, construct, and operate the facility to study the feasibility of high-temperature ATES in a confined aquifer. Four short-term and two long-term cycles were previously conducted, which provided a greatly increased understanding of the efficiency and geochemical effects of high-temperature aquifer thermal energy storage. The third long-term cycle (LT3) was conducted to operate the ATES system in conjunction with a real heating load and to further study the geochemical impact that heated water storage had on the aquifer. For LT3, the source and storage wells were modified so that only the most permeable portion, the Ironton-Galesville part, of the Franconia-Ironton-Galesville aquifer was used for storage. This was expected to improve storage efficiency by reducing the surface area of the heated volume and simplify analysis of water chemistry results by reducing the number of aquifer-related variables which need to be considered. During LT3, a total volume of 63.2 {times} 10{sup 3} m {sup 3} of water was injected at a rate of 54.95 m{sup 3}/hr into the storage well at a mean temperature of 104.7{degrees}C. Tie-in to the reheat system of the nearby Animal Sciences Veterinary Medicine (ASVM) building was completed after injection was completed. Approximately 66 percent (4.13 GWh) of the energy added to the aquifer was recovered. Approximately 15 percent (0.64 GWh) of the usable (10 building. Operations during heat recovery with the ASVM building`s reheat system were trouble-free. Integration into more of the ASVM (or other) building`s mechanical systems would have resulted in significantly increasing the proportion of energy used during heat recovery.

    The aim of this study was to evaluate the efficacy of intra-arterial infusion chemotherapy for head and neck cancers using a coaxial catheter technique: the superficial temporal artery (STA)-coaxial catheter method. Thirty-one patients (21 males and 10 females; 37-83 years of age) with squamous cell carcinoma of the head and neck (maxilla, 2; epipharynx, 4; mesopharynx, 8; oral floor, 4; tongue, 10; lower gingiva, 1; buccal mucosa, 2) were treated by intra-arterial infusion chemotherapy. Four patients were excluded from the tumor-response evaluation because of a previous operation or impossibility of treatment due to catheter trouble. Forty-eight sessions of catheterization were performed. A guiding catheter was inserted into the STA and a microcatheter was advanced into the tumor-feeding artery via the guiding catheter under angiographic guidance. When the location of the tumor or its feeding artery was uncertain on angiography, computed tomographic angiography was performed. The anticancer agent carboplatin (CBDCA) was continuously injected for 24 h through the microcatheter from a portable infusion pump attached to the patient's waist. The total administration dose was 300-1300 mg per body. External radiotherapy was administered during intra-arterial chemotherapy at a total dose of 21-70.5 Gy.The initial response was complete response in 15 patients, partial response in 7 patients, and no change in 5 patients; the overall response rate was 81.5% (22/27). Complication-related catheter maintenance was observed in 15 of 48 sessions of catheterization. Injury and dislocation of the microcatheter occurred 10 times in 7 patients. Catheter infection was observed three times in each of two patients, and catheter occlusion and vasculitis occurred in two patients. Intra-arterial infusion chemotherapy via the STA-coaxial catheter method could have potential as a favorable treatment for head and neck tumors.

    We have developed two case studies to review and analyze energy performance of thermal energy storage CMS systems in commercial buildings. Our case studies considered two partial ice storage systems in Northern California. For each case, we compiled historical data on TES design, installation, and operation. This information was further enhanced by data obtained through interviews with the building owners and operators. The performance and historical data of the TES systems and their components were grouped into issues related to design, installation, operation, and maintenance of the systems. Our analysis indicated that (1) almost all problems related to the operation of TES and non-TES systems could be traced back to the design of the system, and (2) the identified problems were not unique to the TES systems. There were as many original problems with conventional'' HVAC systems and components as with TES systems. Judging from the problems related to non-TES components identified in these two case studies, it is reasonable to conclude that conventional systems have as many problems as TES systems, but a failure, in a TES system may have a more dramatic impact on thermal comfort and electricity charges. The objective of the designers of the TES systems in the case-study buildings was to design just-the-right-size systems so that both the initial investment and operating costs would be minimized. Given such criteria, a system is typically designed only for normal and steady-state operating conditions-which often precludes due consideration to factors such as maintenance, growth in the needed capacity, ease of the operation, and modularity of the systems. Therefore, it is not surprising to find that these systems, at least initially, did not perform to the design intent and expectation and that they had to go through extended periods of trouble-shooting.

    The contribution is focused to present results of study grinded gears made of 18CrNiMo7-6 steel used in the wind power plant for support (service) purposes. These gears were case-hardened due to standard hard case and soft core formation. This heat treatment increases wear resistance and fatigue strength of machine parts. During serial production some troubles with surface integrity have occurred. When solving complex problems lots of samples were prepared. For grinding of gears were used different parameters of cutting speed, number of material removal and lots from different subsuppliers. Material characterization was carried out using Barkhausen noise analysis (BNA) device; X-ray diffraction (XRD) measurement of surface residual stresses was done as well. Depth profile of measured characteristics, e.g. magnetoelastic parameter and residual stress was obtained by step by step layers' removing using electrolytic etching. BNA software Viewscan was used to measure magnetizing frequency sweep (MFS) and magnetizing voltage sweep (MVS). Scanning of Magnetoelastic parameter (MP) endwise individual teeth were also carried out with Viewscan. These measurements were done to find problematic surface areas after grinding such as thermal damaged locations. Plots of the hardness and thickness of case-hardened layer on cross sections were measurered as well. Evaluation of structure of subsurface case-hardened layer and core was made on etched metallographic patterns. The aim of performed measurements was to find correlation between conditions of grinding, residual stresses and structural and magnetoelastic parameters. Based on correlation of measured values and technological parameters optimizing the production of gears will be done.

    In cases where surgery is not possible for lung cancer treatment, stereotactic body radiation therapy (SBRT) may be an option. One problem when treating this type of cancer is the motion of the lungs caused by the patient's respiration. It is possible to reduce the impact of this movement with the use of respiratory gating. By combining respiratory gating with a flattening filter free (FFF) photon beam linac, the increased treatment time caused by a reduced beam-on time of respiratory gating methods can be compensated by the inherent increased dose rate of FFF beams. This project's aim is to create hardware and software interfaces allowing free respiration gating on an Elekta Synergy-S linac specially modified to deliver 6 MV FFF photon beams. First, a printed circuit board was created for reading the signal from a Bellows Belt from Philips (a respiration monitor belt) and transmitting an On/Off signal to the accelerator. A software was also developed to visualize patient respiration. Secondly, a FFF model was created with the Pinnacle treatment planning system from Philips. Gamma (Γ) analysis (2%, 2 mm) was used to evaluate model. For fields going from 5.6 × 5.6 to 12 × 12 cm{sup 2}, central axis depth dose model fitting shows an average gamma value of 0.2 and 100% of gamma values remain under the Γ = 1 limit. For smaller fields (0.8 × 0.8 and 1.6 × 1.6 cm{sup 2}), Pinnacle has more trouble trying to fit the measurements, overestimating dose in penumbra and buildup regions.

    This paper describes an 'Annex', or task, that is part of the International Energy Agency's Geothermal Implementing Agreement. Annex 7 is aimed at improving the state of the art in geothermal drilling, and has three subtasks: an international database on drilling cost and performance, a 'best practices' drilling handbook, and collaborative testing among participating countries. Drilling is an essential and expensive part of geothermal exploration, production, and maintenance. High temperature, corrosive fluids, and hard, fractured formations increase the cost of drilling, logging, and completing geothermal wells, compared to oil and gas. Cost reductions are critical because drilling and completing the production and injection well field can account for approximately half the capital cost for a geothermal power project. Geothermal drilling cost reduction can take many forms, e.g., faster drilling rates, increased bit or tool life, less trouble (twist-offs, stuck pipe, etc.), higher per-well production through multilaterals, and others. Annex 7 addresses all aspects of geothermal well construction, including developing a detailed understanding of worldwide geothermal drilling costs, understanding geothermal drilling practices and how they vary across the globe, and development of improved drilling technology. Objectives for Annex 7 include: (1) Quantitatively understand geothermal drilling costs and performance from around the world and identify ways to improve costs, performance, and productivity. (2) Identify and develop new and improved technologies for significantly reducing the cost of geothermal well construction. (3) Inform the international geothermal community about these drilling technologies. (4) Provide a vehicle for international cooperation, collaborative field tests, and data sharing toward the development and demonstration of improved geothermal drilling technology.

  6. Overview of steam generator tube degradation and integrity issues

    The degradation of steam generator tubes in pressurized water nuclear reactors continues to be a serious problem. Primary water stress corrosion cracking is commonly observed at the roll transition zone at U-bends, at tube denting locations, and occasionally in plugs and sleeves. Outer-diameter stress corrosion cracking and intergranular attack commonly occur near the tube support plate crevice, near the tube sheet in crevices or under sludge piles, and occasionally in the free span. A particularly troubling recent trend has been the increasing occurrence of circumferential cracking at the RTZ on both the primary and secondary sides. Segmented axial cracking at the tubes support plate crevices is also becoming more common. Despite recent advances in in-service inspection technology, a clear need still exists for quantifying and improving the reliability of in- service inspection methods with respect to the probability of detection of the various types of flaws and their accurate sizing. Improved inspection technology and the increasing occurrence of such degradation modes as circumferential cracking, intergranular attack, and discontinuous axial cracking have led to the formulation of a new performance-based steam generator rule. This new rule would require the development and implementation of a steam generator management program that monitors tube condition against accepted performance criteria to ensure that the tubes perform the required safety function over the next operating cycle. The new steam generator rule will also be applied to severe accident conditions to determine the continued serviceability of a steam generator with degraded tubes in the event of a severe accident. Preliminary analyses are being performed for a hypothetical severe accident scenario to determine whether failure will occur first in the steam generator tubes, which would lead to containment bypass, or instead in the hot leg nozzle or surge line, which would not.

    1995-01-01

    Based on several key design criteria and site visits, we developed a Robot design and built a system which automatically strips the lagging and insulation from the pipes, and encapsulates them under complete vacuum operation. The system can operate on straight runs of piping in horizontal or vertical orientations. Currently we are limited to four-inch diameter piping without obstacles as well as a somewhat laborious emplacement and removal procedure. Experimental results indicated that the current robotic abatement process is sound yet needs to be further expanded and modified. One of the main discoveries was that a longitudinal cut to fully allow the paddles to dig in and compress the insulation off the pipe is essential. Furthermore, a different cutting method might be explored to alleviate the need for a deeper cut and to enable a combination of certain functions such as compression and cutting. Unfortunately due to a damaged mechanism caused by extensive testing, we were unable to perform vertical piping abatement experiments, but foresee no trouble in implementing them in the next proposed Phase. Other encouraging results have BOA removing asbestos at a rate of 4-5 ft./h compared to 3 ft./h for manual removal of asbestos with a 3-person crew. However, we feel confident that we can double the asbestos removal rate by improving cutting speed, and increasing the length of the BOA robot. The containment and vacuum system on BOA is able to achieve the regulatory requirement for airborne fiber emissions of 0.01 fibers/ccm/8-hr. shift. Currently, BOA weighs about 117 pounds which is more than a human is permitted to lift overhead under OSHA requirements (i.e., 25 pounds). We are considering designing the robot into two components (i.e., locomotor section and cutter/removal section) to aid human installation as well as incorporating composite materials. A more detailed list of all the technical modifications is given in this topical report.

  8. QER- Comment of Katherine Keenum 1

    Broader source: Energy.gov [DOE]

    As a resident of the town of Richmond, Massachusetts, through which a natural gas pipeline already runs, I am troubled that Kinder Morgan plans to build an additional pipeline through our town to carry fracked gas from Pennsylvania to Dracut, Massachusetts, where it will be used for electrical generation and quite possibly exported. My objections are twofold: (1) On a local level, I object to running a line that has siting problems (e.g., wetlands and ledge), would endanger the town in the event of a rupture, and might require noisy compressors all for no benefit to the area or even the Commonwealth. (2) On a national level, I object to investing further in fossil fuels and new infrastructure to carry them to market. Fracking is a particularly noxious technology, dangerous to regions in which it occurs. The United States needs immediately to begin to reduce our use of fossil fuels by as much as 80% if we are to avoid an irreversible rise of CO2 in the atmosphere to levels that will raise the average global temperature by more than 2ºC. Coal, oil, and natural gas must be phased out, not promoted. The future is with wind and solar power, the immense savings available through increased efficiency in use, and new clean technologies. I hope the Department of Energy will focus its policies on sustainable energy sources and use. Most certainly, it should protect citizens and ratepayers from policies that direct monies from taxes or tariffs toward infrastructure to further fossil fuel industries. Thank you, Katherine Keenum

    This talk is about fishing and the friendships that have resulted in its pursuit. It is also about theoretical physics, and the relationship of imagination and fantasy to the establishment of ideas about nature. Fishermen, like theoretical physicists, are well known for their inventive imaginations. Perhaps neither are as clever as sailors, who conceived of the mermaid. If one doubts the power of this fantasy, one should remember the ghosts of the many sailors who drowned pursuing these young nymphs. An extraordinary painting by J. Waterhouse is shown as Fig. 1. The enchantment of a mermaid must reflect an extraordinary excess of imagination on the part of the sailor, perhaps together with an impractical turn of mind. A consummated relationship with a mermaid is after all, by its very nature a fantasy incapable of realization. To a theoretical physicist, she is symbolic of many ideas we develop. There are many truths known to fisherman in which one might also find parallels to the goals of scientists: (1) A fish is the only animal that keeps growing after its death; (2) Nothing makes a fish bigger than almost being caught; (3) ''...of all the liars among mankind, the fisherman is the most trustworthy.'' (William Sherwood Fox, in Silken Lines and Silver Hooks); and (4) Men and fish are alike. They both get into trouble when they open their mouths. These quotes may be interpreted as reflecting skepticism regarding the honesty of fisherman, and probably do not reflect adequate admiration for a creative imagination. Is it fair to criticize a person for believing a falsehood that he or she sincerely believes to be true? The fisherman simultaneously invents the lie, and believes in it himself. The parallel with theoretical physics is perhaps only approximate, although we physicists may invent stories that we come to believe, on some rare occasions our ideas actually correspond to a more or less true descriptions of nature. These minor philosophical differences are not

In 1998, four Red Valve pressure sensors (with Sensotech Model AE-213 pressure transducers) were installed before and after the booster pumps of the 4-in. slurry (SL-200) and supernatant (SN-200) transfer lines between Tank 241-C-106 and Tank 241-AY-1 02. These pressure sensors have been in operation for over 1 year, and to date, the sensors have been trouble-flee according to the operators involved with slurry and supernatant transfer operations. Based on these observations, it is apparent that the Red Valve pressure sensors could be installed at the end of the slurry transfer lines and used to measure the pressure drop in the system.

  11. ANAEROBIC BIOLOGICAL TREATMENT OF PRODUCED WATER

    During the production of oil and gas, large amounts of water are brought to the surface and must be disposed of in an environmentally sensitive manner. This is an especially difficult problem in offshore production facilities where space is a major constraint. The chief regulatory criterion for produced water is oil and grease. Most facilities have little trouble meeting this criterion using conventional oil-water separation technologies. However, some operations have significant amounts of naphthenic acids in the water that behave as oil and grease but are not well removed by conventional technologies. Aerobic biological treatment of naphthenic acids in simulated-produced water has been demonstrated by others; however, the system was easily overloaded by the large amounts of low-molecular-weight organic acids often found in produced waters. The objective of this research was to determine the ability of an anaerobic biological system to treat these organic acids in a simulated produced water and to examine the potential for biodegradation of the naphthenic acids in the anaerobic environment. A small fixed-film anaerobic biological reactor was constructed and adapted to treat a simulated produced water. The bioreactor was tubular, with a low-density porous glass packing material. The inocula to the reactor was sediment from a produced-water holding pond from a municipal anaerobic digester and two salt-loving methanogenic bacteria. During start-up, the feed to the reactor contained glucose as well as typical produced-water components. When glucose was used, rapid gas production was observed. However, when glucose was eliminated and the major organic component was acetate, little gas was generated. Methane production from acetate may have been inhibited by the high salt concentrations, by sulfide, or because of the lack, despite seeding, of microbes capable of converting acetate to methane. Toluene, a minor component of the produced water (0.1 g/L) was removed in the

    The US Department of Energy has launched the Zero-Net-Energy (ZNE) Commercial Building Initiative (CBI) in order to develop commercial buildings that produce as much energy as they use. Its objective is to make these buildings marketable by 2025 such that they minimize their energy use through cutting-edge energy-efficient technologies and meet their remaining energy needs through on-site renewable energy generation. We examine how such buildings may be implemented within the context of a cost- or carbon-minimizing microgrid that is able to adopt and operate various technologies, such as photovoltaic (PV) on-site generation, heat exchangers, solar thermal collectors, absorption chillers, and passive / demand-response technologies. We use a mixed-integer linear program (MILP) that has a multi-criteria objective function: the minimization of a weighted average of the building's annual energy costs and carbon / CO2 emissions. The MILP's constraints ensure energy balance and capacity limits. In addition, constraining the building's energy consumed to equal its energy exports enables us to explore how energy sales and demand-response measures may enable compliance with the CBI. Using a nursing home in northern California and New York with existing tariff rates and technology data, we find that a ZNE building requires ample PV capacity installed to ensure electricity sales during the day. This is complemented by investment in energy-efficient combined heat and power equipment, while occasional demand response shaves energy consumption. A large amount of storage is also adopted, which may be impractical. Nevertheless, it shows the nature of the solutions and costs necessary to achieve ZNE. For comparison, we analyze a nursing home facility in New York to examine the effects of a flatter tariff structure and different load profiles. It has trouble reaching ZNE status and its load reductions as well as efficiency measures need to be more effective than those in the CA case

    Energy-Saving Melting and Revert Reduction Technology (E-SMARRT) is a balanced portfolio of R&D tasks that address energy-saving opportunities in the metalcasting industry. E-SMARRT was created to: • Improve important capabilities of castings • Reduce carbon footprint of the foundry industry • Develop new job opportunities in manufacturing • Significantly reduce metalcasting process energy consumption and includes R&D in the areas of: • Improvements in Melting Efficiency • Innovative Casting Processes for Yield Improvement/Revert Reduction • Instrumentation and Control Improvement • Material properties for Casting or Tooling Design Improvement The energy savings and process improvements developed under E-SMARRT have been made possible through the unique collaborative structure of the E-SMARRT partnership. The E-SMARRT team consisted of DOE’s Office of Industrial Technology, the three leading metalcasting technical associations in the U.S: the American Foundry Society; the North American Die Casting Association; and the Steel Founders’ Society of America; and SCRA Applied R&D, doing business as the Advanced Technology Institute (ATI), a recognized leader in distributed technology management. This team provided collaborative leadership to a complex industry composed of approximately 2,000 companies, 80% of which employ less than 100 people, and only 4% of which employ more than 250 people. Without collaboration, these new processes and technologies that enable energy efficiencies and environment-friendly improvements would have been slow to develop and had trouble obtaining a broad application. The E-SMARRT R&D tasks featured low-threshold energy efficiency improvements that are attractive to the domestic industry because they do not require major capital investment. The results of this portfolio of projects are significantly reducing metalcasting process energy consumption while improving the important capabilities of metalcastings. Through June

    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.

  16. An Economic Analysis of the Kilauea Geothermal Development and Inter-Island Cable Project

    1990-03-01

    A study by NEA completed in April 1987 shows that a large scale (500 MW) geothermal development on the big island of Hawaii and the inter-island power transmission cable is economically infeasible. This updated report, utilizing additional information available since 1987, reaches the same conclusion: (1) The state estimate of $1.7 billion for development cost of the geothermal project is low and extremely optimistic. more realistic development costs are shown to be in the range of $3.4 to $4.3 billion and could go as high as $4.6 billion. (2) Compared to alternative sources of power generation, geothermal can be 1.7 to 2.4 times as costly as oil, and 1.2 to 1.7 times as costly as a solar/oil generating system. (3) yearly operation and maintenance costs for the large scale geothermal project are estimated to be 44.7 million, 72% greater than a solar/oil generating system. (4) Over a 40-year period ratepayers could pay, on average, between 1.3 (17.2%) and 2.4 cents (33%) per kWh per year more for electricity produced by geothermal than they are currently paying (even with oil prices stabilizing at $45 per barrel in 2010). (5) A comparable solar/oil thermal energy development project is technologically feasible, could be island specific, and would cost 20% to 40% less than the proposed geothermal development. (6) Conservation is the cheapest alternative of all, can significantly reduce demand, and provides the greatest return to ratepayers. There are better options than geothermal. Before the State commits the people of Hawaii to future indebtedness and unnecessary electricity rate increases, more specific study should be conducted on the economic feasibility, timing, and magnitude of the geothermal project. The California experience at The Geyers points up the fact that it can be a very risky and disappointing proposition. The state should demand that proponents and developers provide specific answers to geothermals troubling questions before they make an

    This literature study investigated methods and areas to deduce climate change and climate patterns, looking for short-term cycle phenomena and the means to interpret them. Many groups are actively engaged in intensive climate-related research. Ongoing research might be (overly) simplified into three categories: (1) historic data on weather that can be used for trend analysis and modeling; (2) detailed geological, biological (subfossil), and analytical (geochemical, radiocarbon, etc.) studies covering the last 10,000 years (about since last glaciation); and (3) geological, paleontological, and analytical (geochemical, radiometric, etc.) studies over millions of years. Of importance is our ultimate ability to join these various lines of inquiry into an effective means of interpretation. At this point, the process of integration is fraught with methodological troubles and misconceptions about what each group can contribute. This project has met its goals to the extent that it provided an opportunity to study resource materials and consider options for future effort toward the goal of understanding the natural climate variation that has shaped our current civilization. A further outcome of this project is a proposed methodology based on ''climate sections'' that provides spatial and temporal correlation within a region. The method would integrate cultural and climate data to establish the climate history of a region with increasing accuracy with progressive study and scientific advancement (e. g., better integration of regional and global models). The goal of this project is to better understand natural climatic variations in the recent past (last 5000 years). The information generated by this work is intended to provide better context within which to examine global climate change. The ongoing project will help to establish a basis upon which to interpret late Holocene short-term climate variability as evidenced in various studies in the northern Great Plains, northern

    McClaine, A.W.; Breault, R.W.

    1998-12-31

    A large number of coal preparation plants in the United States are troubled with coal fines and associated plant operation problems. As part of their process, these plants use thermal dryers for producing product coal, cyclones for first-stage recovery of coal fines, and wet scrubbers for the second-stage removal of coal fines carry-over from the dryer exhaust gas. The first challenge for these plants is to recover the clean ultra-fine coal captured in the scrubbers rather than to dispose of it in settling ponds. The second challenge is to mitigate the over-dry fine coal dusting problems in the dryer product. Prior to the completion of this program, the difficulties of the first challenge involving the recovery and use of fine clean coal from the thermal dryer scrubber effluent had not been solved. The second challenge, controlling fine coal dusting, was previously met by applying a solution of surfactants and process water to the over-dry coal fraction. As a result of the demonstration provided by the performance of this program, the implementation of a simple process improvement, involving the use of a thickener in combination with a belt press, simultaneously solved both challenges: the de-dusting and the dryer scrubber effluent recovery issues. The objective of this project was to: (1) Use a clean coal thickener with a squeeze belt press to recover the ultra-fine coal in dryer scrubber effluent; (2) Demonstrate that the coal-water mixture (CWM) produced from scrubber sludge of a thermal dryer can be used as a dust suppressant. The thickener/belt press system has increased the production of JWRI Mine Number 4 by approximately 0.7%. This production increase was accomplished by recovering and re-using 3 metric tons/hr (3.3 tons/hr) of coal fines that were previously sent to holding ponds, returning this as a 50% CWM to de-dust the 430 metric tons/hr (470 tons/hr) of existing dryer production.

    2009-01-01

    The Integrated Gasification Combined Cycle (IGCC) systems are considered as a promising technology for power generation. However, they are not yet in widespread commercial use and opportunities remain to improve system feasibility and profitability via improved process integration. This work focuses on the integrated design of gasification system, air separation unit (ASU) and the gas turbine (GT) block. The ASU supplies oxygen to the gasification system and it can also supply nitrogen (if required as a diluent) to the gas turbine block with minimal incremental cost. Since both GT and the ASU require a source of compressed air, integrating the air requirement of these units is a logical starting point for facility optimization (Smith et al., 1997). Air extraction from the GT can reduce or avoid the compression cost in the ASU and the nitrogen injection can reduce NOx emissions and promote trouble-free operation of the GT block (Wimer et al., 2006). There are several possible degrees of integration between the ASU and the GT (Smith and Klosek, 2001). In the case of 'total' integration, where all the air required for the ASU is supplied by the GT compressor and the ASU is expected to be an elevated-pressure (EP) type. Alternatively, the ASU can be 'stand alone' without any integration with the GT. In this case, the ASU operates at low pressure (LP), with its own air compressor delivering air to the cryogenic process at the minimum energy cost. Here, nitrogen may or may not be injected because of the energy penalty issue and instead, syngas humidification may be preferred. A design, which is intermediate between these two cases, involves partial supply of air by the gas turbine and the remainder by a separate air compressor. These integration schemes have been utilized in some IGCC projects. Examples include Nuon Power Plant at Buggenum, Netherlands (both air and nitrogen integration), Polk Power Station at Tampa, US (nitrogen-only integration) and LGTI at Plaquemine

    2006-12-15

    The Office of Energy Efficiency and Renewable Energy (EERE) has had a longstanding goal of introducing uncertainty into the analysis it routinely conducts in compliance with the Government Performance and Results Act (GPRA) and for strategic management purposes. The need to introduce some treatment of uncertainty arises both because it would be good general management practice, and because intuitively many of the technologies under development by EERE have a considerable advantage in an uncertain world. For example, an expected kWh output from a wind generator in a future year, which is not exposed to volatile and unpredictable fuel prices, should be truly worth more than an equivalent kWh from an alternative fossil fuel fired technology. Indeed, analysts have attempted to measure this value by comparing the prices observed in fixed-price natural gas contracts compared to ones in which buyers are exposed to market prices (see Bolinger, Wiser, and Golove and (2004)). In addition to the routine reasons for exploring uncertainty given above, the history of energy markets appears to have exhibited infrequent, but troubling, regime shifts, i.e., historic turning points at which the center of gravity or fundamental nature of the system appears to have abruptly shifted. Figure 1 below shows an estimate of how the history of natural gas fired generating costs has evolved over the last three decades. The costs shown incorporate both the well-head gas price and an estimate of how improving generation technology has gradually tended to lower costs. The purpose of this paper is to explore scenario analysis as a method for introducing uncertainty into EERE's forecasting in a manner consistent with the preceding observation. The two questions are how could it be done, and what is its academic basis, if any. Despite the interest in uncertainty methods, applying them poses some major hurdles because of the heavy reliance of EERE on forecasting tools that are deterministic in

    The following paper conducts a regional analysis of the U.S. and Chinese buildings? potential for adopting Distributed Energy Resources (DER). The expected economics of DER in 2020-2025 is modeled for a commercial and a multi-family residential building in different climate zones. The optimal building energy economic performance is calculated using the Distributed Energy Resources Customer Adoption Model (DER CAM) which minimizes building energy costs for a typical reference year of operation. Several DER such as combined heat and power (CHP) units, photovoltaics, and battery storage are considered. The results indicate DER have economic and environmental competitiveness potential, especially for commercial buildings in hot and cold climates of both countries. In the U.S., the average expected energy cost savings in commercial buildings from DER CAM?s suggested investments is 17percent, while in Chinese buildings is 12percent. The electricity tariffs structure and prices along with the cost of natural gas, represent important factors in determining adoption of DER, more so than climate. High energy pricing spark spreads lead to increased economic attractiveness of DER. The average emissions reduction in commercial buildings is 19percent in the U.S. as a result of significant investments in PV, whereas in China, it is 20percent and driven by investments in CHP.

Introduction The transition from a centralized and fossil-based energy paradigm towards the decentralization of energy supply and distribution has been a major subject of research over the past two decades. Various concerns have brought the traditional model into question; namely its environmental footprint, its structural inflexibility and inefficiency, and more recently, its inability to maintain acceptable reliability of supply. Under such a troubled setting

    , new technologies enabling energy efficiencies and environment-friendly improvements are slow to develop, and have trouble obtaining a broad application. The CMC team was able to effectively and efficiently transfer the results of DOE's metalcasting R&D projects to industry by utilizing and delivering the numerous communication vehicles identified in the proposal. The three metalcasting technical associations achieved significant technology transition results under this program. In addition to reaching over 23,000 people per year through Modern Casting and 28,000 through Engineered Casting Solutions, AFS had 84 national publications and reached over 1,200 people annually through Cast Metals Institute (CMI) education courses. NADCA's education department reached over 1,000 people each year through their courses, in addition to reaching over 6,000 people annually through Die Casting Engineer, and publishing 58 papers. The SFSA also published 99 research papers and reached over 1,000 people annually through their member newsletters. In addition to these communication vehicles, the CMC team conducted numerous technical committee meetings, project reviews, and onsite visits. All of these efforts to distribute the latest metalcasting technologies contributed to the successful deployment of DOE's R&D projects into industry. The DOE/CMC partnership demonstrated significant success in the identification and review of relevant and easy-to-implement metalcasting energy-saving processes and technologies so that the results are quickly implemented and become general practice. The results achieved in this program demonstrate that sustained technology transfer efforts are a critical step in the deployment of R&D projects to industry.

    . In most cases, sellers do not find legitimate buyers; however, there have been specific cases where sellers did find actual terrorist group representatives. There appears to be a connection between terrorist groups engaged in trafficking conventional arms and explosives components that are also looking for both nuclear materials and radioisotopes. Sale opportunities may create additional demand for such materials. As we can observe from Figure 1, many cases in the mid-90s involved kilogram quantities of material. There were smaller amounts of material moved in 2001, 2003 and 2006. While we have seen less trafficking cases involving PujHEU in recent years, the fact that it continues at all is troubling. The trafficking cases can be presented through their life cycle: Diversion of materials leads to Trafficker and then to Terrorist/Proliferator. Most of the information we have in trafficking cases is on the Trafficker. In 16 cases reported by the IAEA, there are 10 prosecutions of the involved trafficker. However, there are no confirmed diversions of material recorded in any of the 18 seizures. Most seizures were sting operations performed by law enforcement or security agents with no actual illicit end-user involved.

    previously a leakage on inner source housing. Thus, during manufacturing the filled-lead for shielding passed through this small hole and fixed the deformed spring together with the source. The circular surface of inner hole was measured and slowly drilled at a diameter 2.2 cm behind shielding, till the spring and the fixed lead sheet were cut, therefore the source could be finally hammered out. The surface dose rate of coal level gauges before weld cutting was 10-15 mR/hr and the highest dose rate at the position of the weld cutter was 2.5 mR/hr. The total time for each weld cutting and automatic sawing was 2-3 minutes and 1 minute, respectively. The source was individually and safely transferred to store in lead safe box using a 1-meter length tong and a light container with 1 meter length handle. The total time for Ra-226 (70 pieces) dismantling, including the encountered problems and their troubles shooting took 4 days operation in which the total dose obtained by 18 operators were ranged from 1-38 {mu}Sv. The dismantling team safely completed the activities within the effective dose limit for occupational exposure of 20 mSv/year (80 {mu}Sv/day). (authors)

    trutta) had low densities, and limited distribution throughout the basin. A large return of adult spring chinook to the Touchet River drainage in 2001 produced higher densities of juvenile chinook in 2002 than have been seen in recent years, especially in the Wolf Fork. The adult return in 2002 was substantially less than what was seen in 2001. Due to poor water conditions and trouble getting personnel hired, spawning surveys were limited in 2002. Surveyors found only one redd in four Walla Walla River tributaries (Cottonwood Ck., East Little Walla Walla, West Little Walla Walla, and Mill Ck.), and 59 redds in Touchet River tributaries (10 in the North Fork Touchet, 30 in the South Fork Touchet, and 19 in the Wolf Fork). Bull trout spawning surveys in the upper Touchet River tributaries found a total of 125 redds and 150 live fish (92 redds and 75 fish in the Wolf Fork, 2 redds and 1 fish in the Burnt Fork, 0 redds and 1 fish in the South Fork Touchet, 29 redds and 71 fish in the North Fork Touchet, and 2 redds and 2 fish in Lewis Ck.). A preliminary steelhead genetics analysis was completed as part of this project. Results indicate differences between naturally produced steelhead and those produced in the hatchery. There were also apparent genetic differences among the naturally produced fish from different areas of the basin. Detailed results are reported in Bumgarner et al. 2003. Recommendations for assessment activities in 2003 included: (1) continue to monitor the Walla Walla River (focusing from the stateline to McDonald Rd.), the Mill Ck system, and the Little Walla Walla System. (2) reevaluate Whiskey Ck. for abundance and distribution of salmonids, and Lewis Ck. for bull trout density and distribution. (3) select or develop a habitat survey protocol and begin to conduct habitat inventory and assessment surveys. (4) summarize bull trout data for Mill Ck, South Fork Touchet, and Lewis Ck. (5) begin to evaluate temperature and flow data to assess if the habitat

    the 2-bed configuration with recirculation in both beds was 65-70% with a high flue gas CO₂ loading (~7%) and up to 85% with a low flue gas CO₂ loading (~4%). A sorbent regenerator system consisting of a pre-heater, desorber, and cooler is used to heat the CO₂-rich sorbent with direct and indirect steam producing a nearly 100% pure stream of CO₂. Parametric testing of the regenerator system demonstrated the impact of process conditions on both desorption rate and the heat of regeneration. Clear evidence of the use of specific process conditions that lower the overall energy of desorption was identified. This observation validates measurements made at the laboratory-scale. Several longer-term continuous tests were conducted to evaluate the performance of the sorbent/process as a function of time. Using a 2-bed configuration, sustained capture efficiency of 40-60% with a high flue gas CO₂ loading (~8%) and 70-80% with a low flue gas CO₂ loading (~4%) were achieved. However, sorbent working capacity was found to be considerably lower than laboratory-scale measurements. The low working capacity is attributed to insufficient sorbent/gas contact time in the adsorber. Sorbent properties that had a significant impact on CO₂ capture performance were identified. The results show that controlling these sorbent properties substantially improves CO₂ capture performance, with preliminary estimates indicating that relative improvement of ~30% is possible. Testing culminated with an operationally trouble-free test of 15 hours with sustainable performance. Overall, several practical strategies to increase performance of the sorbent and process were identified. The initial technical and economic assessment of the CACHYS™ process estimated the cost of CO2 capture was $36.19/ton with a 48.6% increase in levelized cost of electricity (LCOE) for the 550 MWe net plant. Using additional data gathered over the course of the project, and with revised technical and economic
