    Office equipment is expected to be the fastest-growingsegment of commercial energy use over the next 20 years, yet many aspectsof office equipment energy use are poorly understood. User behavior, suchas turning off devices at night or enabling power management, influencesenergy use to a great extent. The computing environment also plays a roleboth in influencing user behavior and in the success of power management.Information about turn-off rates and power management rates for officeequipment was collected through a series of after-hours audits incommercial buildings. Sixteen businesses were recruited, includingoffices (small, medium and large offices in a variety of industries),schools, and medical buildings in California, Georgia, and Pennsylvania.The types and power states of office equipment found in these buildingswere recorded and analyzed. This article presents these data forcomputers, monitors, printers, copiers, fax machines, scanners andmulti-function devices. These data can be used to improve estimates ofboth energy consumption for these devices and savings from energyconservation efforts.

    This research was conducted in support of two branches of the EPA ENERGY STAR program, whose overall goal is to reduce, through voluntary market-based means, the amount of carbon dioxide emitted in the U.S. The primary objective was to collect data for the ENERGY STAR Office Equipment program on the after-hours power state of computers, monitors, printers, copiers, scanners, fax machines, and multi-function devices. We also collected data for the ENERGY STAR Commercial Buildings branch on the types and amounts of ''miscellaneous'' plug-load equipment, a significant and growing end use that is not usually accounted for by building energy managers. This data set is the first of its kind that we know of, and is an important first step in characterizing miscellaneous plug loads in commercial buildings. The main purpose of this study is to supplement and update previous data we collected on the extent to which electronic office equipment is turned off or automatically enters a low power state when not in active use. In addition, it provides data on numbers and types of office equipment, and helps identify trends in office equipment usage patterns. These data improve our estimates of typical unit energy consumption and savings for each equipment type, and enables the ENERGY STAR Office Equipment program to focus future effort on products with the highest energy savings potential. This study expands our previous sample of office buildings in California and Washington DC to include education and health care facilities, and buildings in other states. We report data from twelve commercial buildings in California, Georgia, and Pennsylvania: two health care buildings, two large offices (> 500 employees each), three medium offices (50-500 employees), four education buildings, and one ''small office'' that is actually an aggregate of five small businesses. Two buildings are in the San Francisco Bay area of California, five are in

    Neil, Amanda L; Nelson, Mark; Palmer, Andrew J

    2016-07-01

    In July 2015, a national scheme for after-hours incentive funding for general practices was re-introduced in Australia, 2-years after funding was transferred to regional primary health care organisations (Medicare Locals). The re-introduction was recommended in a 2014 review of after-hours primary care reflecting the "overwhelming desire" among general practice. Given the centrality of after-hours care provision in rural and remote practices identified in the review, we compare and contrast the current and historical after-hours incentive funding mechanisms focussing on fairness towards rural general practices. While there are similarities between the current and historical mechanisms, significant differences exist. The comparison is not straightforward. The major consistency is utilisation of practice standardised whole patient equivalents (SWPE) as the basis of funding, inherently favouring large urban general practices. This bias is expected to increase given a shift in focus from practices with no option but to provide 24/7 care to any practice providing 24/7 care; and an associated increased funding per SWPE. Differences primarily pertain to classification processes, in which the realities of rural service provision and recognition of regional support mechanisms are given minimal consideration. Rapid introduction of the new general practice after-hours incentive funding mechanism has led to inconsistencies and has exacerbated inherent biases, particularly inequity towards rural providers. Impact on morale and service provision in non-urban areas should be monitored.

    A strong primary healthcare system that is effective and efficient is a priority for health reform in Australia. Commissioning to support primary healthcare delivery has received increasing attention as part of healthcare reform in Australia and beyond. The aim of this paper is to present a case study of transitioning to an activity-based model for the provision of GP after-hours services in Australia. The GP After-Hours Program utilised a commissioning model that comprised of needs assessment, service development, provider engagement and evaluation. Evaluation of the new model showed a 17% increase in after-hours services, with service providers indicating that they were satisfied with the new process. Examination of the experience of implementation suggests that the commissioning model provided a useful framework for guiding activity-based funding for after-hours services. However, relational factors, such as engagement with the community, knowledge of the wider context and legitimacy of the commissioning body, can affect the implementation process. PMID:27469050

    1996-03-01

    Development of the superconducting transformer is arguably the most difficult of the ac power applications of superconductivity - this is because of the need for very low ac losses, adequate fault and surge performance, and the rigors of the application environment. This paper briefly summarizes the history of superconducting transformer projects, reviews the key issues for superconducting transformers, and examines the status of HTS transformer development. Both 630-kVA, three-phase and 1-MVA single phase demonstration units are expected to operate in late 1996. Both efforts will further progress toward the development of economical and performance competitive superconducting transformers.

    2014-04-01

    This study reviews the clinical and workforce impact of a suggested protocol designed for the management of suspected acute deep venous thrombosis (DVT) in patients seen after standard vascular laboratory business hours. The protocol included the use of Wells score, D-dimer and a single dose of therapeutic anticoagulant to defer venous duplex ultrasound (VDU) testing until routine business hours unless contraindicated. Information was collected on medical history, physical exam and the timing of any diagnostic studies and treatment provided. Over 15% of studies done after-hours were deemed unnecessary by our protocol and in every individual the results were negative for an acute DVT. There were no adverse events from a one-time dose of anticoagulant. Limiting emergency VDU coverage to evaluate for acute DVT based on a management protocol can eliminate unnecessary after-hours VDU testing without having a negative impact on patient care.

    Musgrove, J P; Waghorne, M S

    1977-04-27

    The results of a postal questionnaire to 185 general practitioners in the Canterbury-Westland agea are discussed. The intention was to describe the after hours provision for patients made by general practitioners. The study indicates that about one half of doctors are on call on weekdays evenings and about a third on weekends. Only a handful of doctors provide no cover. The kind of cover provided is discussed and the patient load during such hours is analysed. Figures are presented which suggest that Canterbury practitioners are marginally younger than the national average; that most doctors (100 out of 106 responding) have formal cover arrangements; that 82% are on duty no more than one weekend a month (less often for group practitioners); that about two-thirds have a regular half-day free during the week; that about two-thirds of after hours call are judged to be justified.

    Full Text Available Medical records of equine after-hours admissions from 1998 to 2007 are reviewed. Data extracted from the medical records included signalment, reason for admission, pre-admission treatment, clinical presentation, procedures performed, final diagnoses, complications occurring in hospital, length of stay and outcome. Eight hundred and twenty after-hours admissions were available of which 75 % were classified as emergencies. Most horses originated from Gauteng province (82 %, with Thoroughbred, Arabian, and Warmbloods representing 46 %, 10 % and 7 % of horses. Horses had a median age of 7 years and were predominantly male (60 %. Gastrointestinal (64 % and musculoskeletal (19 % disorders were the primary reasons for admission. Anti-inflammatories, sedation and antibiotics were given in 51 %, 20 % and 15 % of cases respectively prior to referral. On admission, 23 % of horses had surgical intervention. Intravenous catheterisation (64 %, rectal examination (61 %, nasogastric intubation (56 %, abdominocentesis (33 % and ultrasonography (19 % were the procedures performed most frequently. Surgical and medical colics constituted 28 % and 27 % respectively of the overall diagnoses, while piroplasmosis was diagnosed in 5 % of horses. Post-admission complications occurred in <2 % of horses. The median length of stay was 4 days (95 % CI: 1 to 21 days. Overall survival to discharge was 74 %. This study demonstrates that the majority of after-hours equine admissions to a university referral hospital required medical intervention and were mostly due to gastrointestinal disorders. Information obtained from this study can be used in emergency referral planning.

  19. The status and future of geothermal power

    2000-08-01

    Geothermal electricity production in the United States began in 1960. Today there are over 20 plants in the western United States providing a total of about 2,200 MW of clean and reliable electricity. Currently identified resources could provide over 20,000 MW of power in the U.S., and undiscovered resources might provide 5 times that amount. In the 1990s industry growth slowed due to the loss of market incentives and competition from natural gas. However, increased interest in clean energy sources, ongoing technological improvements, and renewed opportunities abroad hold promise for a resurgence in the industry. This review paper covers the status of the technology, the issues faced, and the latest research. While the focus is on geothermal in the U.S., a brief description of the large international market is included.

    of this reorganization on the use of services by frequent attenders (FAs). METHODS: From 1990 to 1994, methods of contact and annual costs per attender were analyzed in an ecological time-trend study based on aggregated administrative data collected from the database of the Public Health Insurance, Aarhus County......, Denmark (600,000 inhabitants). The study only included attenders ages 18 and over. FAs were defined as the group that, within each calendar year (12 months), had 4 or more contacts with the after-hours family practice service. RESULTS: FAs made up 9.5% of the attenders and accounted for more than 40......% of the contacts and the aggregate costs. The effect of the reorganization was a 12% decrease in the number of attenders, a 16% decrease in the number of contacts, and a 29% decrease in the costs. Reorganization had a significantly bigger effect on FA attendance than on non-FA attendance, and more than half...

    The 24-hour support for palliative patients is the gold standard of health care in Australia. However, in the state of Tasmania after-hours telephone support was spatially fragmented and inequitable. In 2014, hospice@HOME, a pilot programme introduced in Tasmania in that year, implemented a state-wide after-hours palliative care support service--1800HOSPICE--offering 24-hour support, 7 days a week for palliative patients, caregivers and the public. Six months of after-hours call logs in combination with additional patient data, were analysed to evaluate the use and wider implications of a state-wide after-hours palliative care support number. Family and caregivers mainly used the after-hours support to request changes to support services (25.1%), report changes in patients' overall condition (23.6%) and request acute medical assistance (16.2%). Through the use of the after-hours services by all individuals involved in the care, end-of-life patients were able to reduce ambulance contact and emergency department admission, and thereby increase their likelihood of dying at home (for patients whose preference was to die at home). Overall, 24-hour palliative care telephone support was found to be a valuable tool for all individuals involved in the care of end-of-life patients.

  2. Current status of nuclear power development

    International Nuclear Information System (INIS)

    Nuclear power is not a viable energy source for Sri Lanka at present because of a number of reasons, the main reason being the non-availability of small and economically viable nuclear power plants. However several suppliers of nuclear power plants are in the process of developing small and medium power plants (SMPRs) which could be economically competitive with coal. The paper deals with past and future trends of nuclear power plants, their economics and safety. It also deals with environmental effects and public acceptance of nuclear power plants

    2010-01-01

    Power is a critical consideration in planning exploration of the surfaces of the Moon, Mars, and beyond. Nuclear power is an important option, especially for locations in the solar system where sunlight is limited in availability or intensity. NASA is maintaining the option for fission surface power for the Moon and Mars by developing and demonstrating technology for an affordable fission surface power system. Because affordability drove the determination of the system concept that this technology will make possible, low development and recurring costs result, while required safety standards are maintained. However, an affordable approach to fission surface power also provides the benefits of simplicity, robustness, and conservatism in design. This paper will illuminate the multiplicity of benefits to an affordable approach to fission surface power, and will describe how the foundation for these benefits is being developed and demonstrated in the Exploration Technology Development Program s Fission Surface Power Project.

  9. Status of power sector restructuring in Lithuania

    International Nuclear Information System (INIS)

    Lithuanian electricity sector comprises joint stock company Lietuvos Energija, which is responsible for supplying the country with electric energy, the Ignalina NPP state enterprise, which generates more then three fourth of the entire electricity of Lithuania, CHPs run By municipalities of Kaunas and Vilnius, and a few power plants, owned by industrial enterprises, as well as private small hydro power plants. Joint stock company Lietuvos Energija is a vertically integrated monopoly, which has inherited drawbacks inherent in planned - administrational economy and is therefore now being restructured into a modern and effective structure capable of operating within market economy conditions. The main goals of restructuring would meet electricity economy requirements: clearly un bundle electricity generation costs from electricity transmission and distribution costs; create internal and external electricity market conditions by gradual transition to wholesale and retail electricity trade; create conditions for third party access; create favourable conditions for competition; provide a possibility to integrate with Baltic electricity market in progress

  10. International status and prospects of nuclear power

    International Nuclear Information System (INIS)

    Nuclear power plants are primarily used for electricity production. Currently, 439 reactors are operating in 30 countries and are contributing approximately 14% to global electricity generation. The share of nuclear in global electricity generation has declined slightly in recent years. However, the total amount of nuclear electricity generation is increasing as plant availability, power uprating, and new plants offset the loss from older plants that are being shut down. Due to the economic benefits of continuing operation of a plant after the capital cost has been repaid, and with careful plant life management assessments, a number of reactors have had their operating licences extended for an additional 20 years. Light water reactors (LWRs) are by far the most prevalent reactors in use today, followed by pressurized heavy water reactors, gas cooled reactors and, currently, two fast reactors. The safety and reliability of nuclear facilities have been steadily improving. Strong networks among countries with operating nuclear power plants have enabled operators to learn from each other and to address common issues. Ongoing efforts have continuously strengthened safety culture and regulatory oversight. The current available supply of uranium meets the demand. Current enrichment and fuel fabrication capacities are adequate to meet the expected demand for the next decade. There is also substantial experience in the storage and reprocessing of spent fuel and the treatment of high level waste. Existing reprocessing capacity is adequate to meet present demand. Most spent fuel continues, however, to be stored awaiting a decision on future policy, i.e. whether to reprocess and recycle it or to dispose of it as waste. To date, no ultimate disposal facilities are available. Only a few countries currently use civil nuclear energy for purposes other than electricity production - mainly for seawater desalination and district heating - and even then only to a limited extent

    1996-12-31

    Fuel cell technologies for stationary power are set to play a role in power generation applications worldwide. The worldwide fuel cell vision is to provide powerplants for the emerging distributed generation and on-site markets. Progress towards commercialization has occurred in all fuel cell development areas. Around 100 ONSI phosphoric acid fuel cell (PAFC) units have been sold, with significant foreign sales in Europe and Japan. Fuji has apparently overcome its PAFC decay problems. Industry-driven molten carbonate fuel cell (MCFC) programs in Japan and the U.S. are conducting megawatt (MW)-class demonstrations, which are bringing the MCFC to the verge of commercialization. Westinghouse Electric, the acknowledged world leader in tubular solid oxide fuel cell (SOFC) technology, continues to set performance records and has completed construction of a 4-MW/year manufacturing facility in the U.S. Fuel cells have also taken a major step forward with the conceptual development of ultra-high efficiency fuel cell/gas turbine plants. Many SOFC developers in Japan, Europe, and North America continue to make significant advances.

  15. Status of magnetically-insulated power transmission theory

    International Nuclear Information System (INIS)

    The theory of magnetically-insulated power flow has improved dramatically over the last two decades. Theoretical improvements included a complete general kinetic theory that involved distributions of electrons based on quasi-conserved canonical variables and was used to study flow stability and to analyze simulations and pulsers with voltage adders. The status of theory at this time allowed us to understand many features of these flows, but did not allow detailed analysis for design and data interpretation. Recent theoretical advances have drastically changed this situation. Two recent static models based on layered flows have allowed us to understand and to improve power coupling in voltage adders, current adders, plasma opening switches and in systems where the vacuum impedance varies along the flow. A dynamic model based upon electrons flowing in one or more thin layers has permitted detailed self-consistent time-dependent calculations which include electron flow. This model accurately predicts experimental and simulation data. (author). 3 figs

    The Tampa Electric Company Polk Power Station is a nominal 250 MW (net) Integrated Gasification Combined Cycle (IGCC) power plant located to the southeast of Tampa, Florida in Polk County, Florida. This project is being partially funded under the Department of Energy`s Clean Coal Technology Program pursuant to a Round II award. The Polk Power Station uses oxygen-blown, entrained-flow IGCC technology licensed from Texaco Development Corporation to demonstrate significant reductions of SO{sub 2} and NO{sub x} emissions when compared to existing and future conventional coal-fired power plants. In addition, this project demonstrates the technical feasibility of commercial scale IGCC and Hot Gas Clean Up (HGCU) technology. The Polk Power Station achieved ``first fire`` of the gasification system on schedule in mid-July, 1996. Since that time, significant advances have occurred in the operation of the entire IGCC train. This paper addresses the operating experiences which occurred in the start-up and shakedown phase of the plant. Also, with the plant being declared in commercial operation as of September 30, 1996, the paper discusses the challenges encountered in the early phases of commercial operation. Finally, the future plans for improving the reliability and efficiency of the Unit in the first quarter of 1997 and beyond, as well as plans for future alternate fuel test burns, are detailed. The presentation features an up-to-the-minute update on actual performance parameters achieved by the Polk Power Station. These parameters include overall Unit capacity, heat rate, and availability. In addition, the current status of the start-up activities for the HGCU portion of the plant is discussed.

  18. 700 C power plant technology. Status and challenge

    Energy Technology Data Exchange (ETDEWEB)

    Tschaffon, Helmut [E.ON Energie AG, Muenchen (Germany)

    2010-07-01

    Coal will remain an indispensable major source of energy for power generation in the world in the coming decades, because there are resources for hundreds of years. Coal fired power plants can be operated very flexible which gets increasing importance due to the stochastic input from regenerative energies like wind and solar energy. Sustainable technologies for cool-fired power plants have to be developed to optimise environmental protection and to save valuable resources and reduce CO{sub 2}-emissions. Future coal fired steam power plants aim an elevated steam temperature of about 700 C to reach a net efficiency of about 50%. This paper will give an overview over the status of the development of the 700 C technology and will highlight the challenges to be overcome before their commercial use. The European way to a 700 C Power plant started with the project AD700 in the year 1998. In this project the basic design of a 400 MW demo plant was done and some material tests and component qualifications for nickel-based alloys and new austenitic steels were started and terminated. AD700 delivered the basis of the design of the Component Test Facility COMTES700 (RFCS funded project with European manufacturers and utilities). COMTES 700 was operated between 2005 and 2009. It was integrated into the E.ON power plant Scholven in Germany to test mainly nickel based materials and power plant components. In the project NRWPP700 (2006-2010, funded by NRW and financed by European utilities) the detail design of the steam generator, piping system and turbine of a 500 MW power plant was done. In 7 material projects the qualification of components and materials was supported. At the same time of lot of national and international R and D projects (e.g. MARCKO and COORETEC) were performed. Due to the high amount of these projects they cannot be mentioned here in a detailed way. In 2007 the E.ON project 50plus was started. The aim was to plan and build a 700 C demo plant in

  20. Power in group contexts: the influence of group status on promotion and prevention decision making.

    Science.gov (United States)

    Scheepers, Daan; Ellemers, Naomi; Sassenberg, Kai

    2013-06-01

    This research examines how group status affects the impact of individual power positions on promotion versus prevention choices in group decision making. We consider that high power not only implies control, but also indicates responsibility for the achievement of group goals. We argue that the nature of these goals depends on the current status of the group. In Experiment 1, individuals who were accorded high power showed more promotion-oriented decisions in the low group status condition while decisions were more prevention oriented under high group status. Experiment 2 replicated these effects, and further demonstrated that they only emerge when those in power are explicitly made accountable for the achievement of group goals. These results are discussed in relation to regulatory focus theory, power theories, and the role of social identities and group goals in group dynamics.

    The voluntary green power market refers to the sale and procurement of renewable energy for voluntary purposes by residential and commercial customers. This report reviews seven green power procurement mechanisms: utility green pricing programs, utility green tariffs, voluntary unbundled renewable energy certificates, competitive supplier green power, community choice aggregations, voluntary power purchase agreements (PPAs), and community solar. This report details the status of trends of those seven green power procurement mechanisms in 2015. Three trends -- significant growth of the voluntary PPA project pipeline, innovative green power mechanisms developed by utilities, and geographic expansion of green power mechanisms -- suggest that the green power market is likely to continue to grow in coming years.

    Full Text Available Abstract Background Primary health care providers play a dominant role in the provision of palliative care (PC in Australia but many gaps in after hours service remain. In some rural areas only 19% of people receiving palliative care achieve their goal of dying at home. This study, which builds on an earlier qualitative phase of the project, investigates the gaps in care from the perspective of general practitioners (GPs and PC nurses. Methods Questionnaires, developed from the outcomes of the earlier phase, and containing both structured and open ended questions, were distributed through Divisions of General Practice (1 urban, 1 rural, 1 mixed to GPs (n = 524 and through a special interest group to palliative care nurses (n = 122 in both rural and urban areas. Results Questionnaires were returned by 114 GPs (22% and 52 nurses (43%. The majority of GPs were associated with a practice which provided some after hours services but PC was not a strong focus for most. This was reflected in low levels of PC training, limited awareness of the existence of after hours triage services in their area, and of the availability of Enhanced Primary Care (EPC Medicare items for care planning for palliative patients. However, more than half of both nurses and GPs were aware of accessible PC resources. Factors such as poor communication and limited availability of after hours services were identified the as most likely to impact negatively on service provision. Strategies considered most likely to improve after hours services were individual patient protocols, palliative care trained respite carers and regular multidisciplinary meetings that included the GP. Conclusion While some of the identified gaps can only be met by long term funding and policy change, educational tools for use in training programs in PC for health professionals, which focus on the utilisation of EPC Medicare items in palliative care planning, the development of advance care plans and good

  3. Nuclear power: status, outlook, guarantees of sustainable development

    International Nuclear Information System (INIS)

    Full text: The principal advantages of nuclear power - almost unlimited fuel resources, its high energy capacity, ecological compatibility with a possibility of high wastes concentration - determine the large-scale nuclear power development. The signs of large-scale power - a large rate (dozens of percent) in electricity production, diverse areas (electricity, heat supply, technologies, transport) and media of application (land, ocean, space), extension of number of user countries, diversified power systems (centralized, autonomous), obligatory reproduction and reuse of produced fuel - create various requirements to nuclear power installations of the future. Economic efficiency and competitiveness, safety (of reactors and fuel cycle with waste), proper characteristics of nuclear fuel reproduction, guarantees of nuclear arm's non-proliferation and, particularly, public acceptance are the conditions of such nuclear power development. The up-to-date situation is the following: the 441 nuclear power-generation units with total installed power of 377.36 GW el. (in 31 countries) supply by 1/6 part of the world electric-power consumptions. The 32 units are in stage of the construction. To the present mid-century the level of the nuclear power production, as supposed, must be increased 4-5 times at the following scenario of a regional distribution of nuclear electric powers, GW: USA, Europe and developed countries of Eastern Asia - 1000, FSU-countries - 100 and developing countries - 400

  10. Technological implications of fusion power: requirements and status

    International Nuclear Information System (INIS)

    The major technological requirements for fusion power, as implied by current conceptual designs of fusion power plants, are identified and assessed relative to the goals of existing technology programs. The focus of the discussion is on the tokamak magnetic confinement concept; however, key technological requirements of mirror magnetic confinement systems and of inertial confinement concepts will also be addressed. The required technology is examined on the basis of three general areas of concern: (a) the power balance, that is, the unique power handling requirements associated with the production of electrical power by fusion; (b) reactor design, focusing primarily on the requirements imposed by a tritium-based fuel cycle, thermal hydraulic considerations, and magnet systems; and (c) materials considerations, including radiation damage effects, neutron-induced activation, and resource limitations

  11. Current status of SMPRs and manpower development for nuclear power

    International Nuclear Information System (INIS)

    The development of SMPRs could make it possible for countries with small electrical grids to use nuclear power. SMPRs are still in the developing stages and none of them have the capability of good plant performance. Most of the SMPRs are in the 300 MWe range and a grid capacity of at least 2000 MWe would be required before such a power plant can be connected to the grid. There is a possibility that SMPRs could generate electricity cheaper coal plants requiring desulphurization. An unexpected increase in coal price and adverse environmental effects could make it necessary to use nuclear power in the future. Qualified manpower is required to plan, build and properly operate a nuclear power plant; and the availability of qualified manpower is a pre-condition for deciding to use nuclear power. There is a possibility that Sri Lanka would be able to use nuclear power in the next 15-20 years and a total dependence upon foreign expertise is neither possible nor desirable. Therefore pre-project activities should be considering such things as teaching nuclear science and engineering in the universities and retraining existing professionals, say from the coal power industry. Adequate emphasis must be given to manpower development and to the need to scheduling this development

  7. Nuclear Power in the USSR: Status and prospects

    International Nuclear Information System (INIS)

    The USSR has the great nuclear history: investigations on nuclear physics, nuclear weapon and submarines, the first reactor, fundamentals of controlled thermonuclear fusion, the first NPP, the first commercial fast reactor, nuclear ice-breakers. At present the total capacity of Veer - and RBMK - based NPPs is about 38 GW: nuclear share in overall electricity production is about 13%. The Chernobyl accident hindered implementation of the nuclear program in the USSR. Measures on enhancement of the safety of NPPs in operation: development of enhanced-safety NPPs. The anti-nuclear opposition in the society, the economic crisis and switch - over to market economy with unavoidable correction of the economic strategy represent the factors of uncertainty for nuclear power development in the near future. The primary tasks are: - to ensure safe operation of NPPs, to rehabilitate nuclear power in the public opinion: - to develop enhanced-safety NPPs and to launch the program to their limited construction instead of out dated conventional NPPs: - to develop and demonstrate to the society a new large-scale nuclear power technology capable to solve radically the fuel and power problems of the country in the next century. The main criteria of the new nuclear technology are the drastic enhancement of safety, breeding, preservation of economic advantages of nuclear power through Systematically following the principle of inherent safety. The conceptual development of an NPP with a liquid-lead cooled fast reactor with the use of experience gained in the USSR is the example of such an approach. The same approach is considered as a basis of solving the problem of rad waste management: burning of actinides in fast reactors, long-term controlled storage of residuary rad waste followed by final disposal without violation of natural radiation balance

    As photovoltaic (PV) electrical power systems gain increasing acceptance for both off-grid and utility-interactive applications, the safety, durability, and performance of these systems gains in importance. Local and state jurisdictions in many areas of the country require that all electrical power systems be installed in compliance with the requirements of the National Electrical Code{reg_sign} (NEC{reg_sign}). Utilities and governmental agencies are now requiring that PV installations and components also meet a number of Institute of Electrical and Electronic Engineers (IEEE) standards. PV installers are working more closely with licensed electricians and electrical contractors who are familiar with existing local codes and installation practices. PV manufacturers, utilities, balance of systems manufacturers, and standards representatives have come together to address safety and code related issues for future PV installations. This paper addresses why compliance with the accepted codes and standards is needed and how it is being achieved.

  9. Present status and prospects of nuclear power development in China

    International Nuclear Information System (INIS)

    Energy resource is an essential prerequisite for realizing the strategic objectives of the national economic development in China. By the end of this century the objectives of the national economic development are as follows: the national annual gross value of industrial and agricultural output will be quadrupled as that in 1980; the annual average revenue per capita is expected to be 800-1000 U.S. dollars. For realizing these objectives, a significant discrepancy is anticipated between the energy demand and energy supplied. It is concluded, therefore, that the utilization of nuclear power should be regarded as one of the components constituting China's energy resources. From a longterm point of view, nuclear power will play an even more important role with each passing day. (author)

  10. China's nuclear power policy and the present development status

    International Nuclear Information System (INIS)

    Experience acquired in China 's nuclear power development has proven that it is very important to strengthen exchange in nuclear science and technology, and further to share and to introduce techniques, funds, management experience and experts from abroad. China will continue to keep and to extend international cooperation in the nuclear field on basis of equality and mutual benefit to make a great contribution to the world's peace and economic prosperity.

  11. Chernobyl and status of nuclear power development in the USSR

    International Nuclear Information System (INIS)

    The Chernobyl accident has seriously affected development of the USSR nuclear power program. But it has not eliminated the basic prerequisites for nuclear power development in the USSR which are: - resources and consumption territorial disproportions; - large share of oil and gas in electricity generation; - negative ecological aspects of coal plants; - high power industry development rate. At the same time it has aggravated the old problems and has given rise to some new-ones of which the most important are: - increased safety requirements; rise in costs; longer construction schedules; public opinion. On the whole for further safe development of nuclear power a detailed analysis of the Chernobyl accident is required, including studies of long-term accident consequences and measures of their mitigation and elimination. A necessary condition for NPP operation to be continued would also be development and rapid implementation of technical approaches which would permit to eliminate the design shortcomings in the RBMK NPPs both operating and those under construction. At the same time we have to ensure their competitiveness with other energy sources and possibility of expansion of their applications. The problem of public opinion should be emphasised. After the Chernobyl accident we have faced a social phenomenon which is quite new in this country. There is almost no site where the population was not opposed to NPP construction. For us these problems are especially difficult as we have had no experience of this kind of interactions with the public. We are planning and begin to realize a program basing on the current world experience. This program includes primarily a wide series of publications on the problems of nuclear energy its ecologic and economic advantages as compared with conventional and alternative energy sources,, using all cur-rent media. Centers of public information discussion clubs, exhibitions etc are being organized. In particular, our Institute has

  14. The legal status of nuclear power in Germany

    International Nuclear Information System (INIS)

    Over the past 15 years, political attitudes in Germany towards the nuclear industry have been characterised less by consistency than by some major policy shifts, and the same can be said for the legislation born of these attitudes. Although a number of these about-turns were predictable, others were less so because of their dependence on external factors. What now looks likely to be the final decision to phase out the civil use of nuclear power in Germany by 31 December 2022 raises a whole host of legal questions. In particular, the procedure followed to implement this phase-out provides ample material for debates on questions of constitutionality. Further matters of jurisprudential interest include the agreements concluded with the nuclear industry before the final phase-out decision was taken and the chronologically close political about-faces themselves. Finally, a degree of legal uncertainty still surrounds not only the as yet still unresolved issue of final repositories but also the resurgent debate over the source of funding for the dismantling of nuclear power plants. After providing an overview of the initial situation and the problems arising in connection with Germany's phasing out of the civil use of nuclear energy, this paper will place these issues in their proper legal context before evaluating them and highlighting the connection between these points of nuclear law and the current upheaval in German energy policy.

  17. Reviewing the Great Power Attributes and the Status of the Ottoman Turkey and the Mughal India as Great Powers

    Directory of Open Access Journals (Sweden)

    Ziaul Haque Sheikh

    2016-04-01

    Full Text Available Some intellectuals and scholars in International Relations (IR and the History in their writings about the rise and fall of great powers in the international system, generally exclude Asiatic powers, like the Ottoman Empire in West Asia and Eastern Europe, Safavid Empire in Persia, Mughal Empire in India and Ming Empire in China from the status of great power. Their main arguments are that these Empires were very traditional in political and cultural attitudes and orthodox towards initiatives, military and economic reforms, did not show much prospective in strategic culture, and increasingly suffered from the defects of being despotic and centralized form of government. Therefore, they hardly contribute in the development of international system. Another group of scholars believes that such arguments express their Western-centric approach and these intellectuals view that by any absolute measure of great power attributes, the Ottoman Turkey, Ming China, Mughal India and Safavid Persia were great powers for all or most of the period 1500 -1750 AD. However, the aim of this paper is to explore such dichotomy and to find out the answers to the two underlined questions that are still been unsettled – were the Ottoman Turkey and Mughal India great powers? If so, why did they fail to maintain their status in the 19th and 20th centuries?

    2015-10-16

    NREL's annual report on green power markets summarizes status and trends in the voluntary demand for renewable energy. U.S. green power markets have become more complex over time as state-level policies have enabled more avenues for green power purchases. In recent years, community solar, community choice aggregation (CCA), and voluntary power purchase agreements (PPAs) have significantly increased the number of U.S. voluntary green power customers. The community solar model has grown rapidly with 90 projects in 25 states by 2015. Renewable energy sales in CCAs declined slightly in 2014 in response to less favorable economic conditions in Illinois. At the same time, several California CCAs continued to grow, and many more communities are planning to pursue green power through aggregation. Voluntary green power purchasing through bi-lateral PPAs took off in 2014 due to several large-scale agreements signed by information and communication technology firms. Traditional green power options, such as utility green pricing programs and voluntary RECs markets, also grew in 2014. Current trends suggest strong continued growth in U.S. voluntary green power markets.

    Remote power controllers (RPCs) are solid state devices that combine in one unit the capability to perform all the needed functions of load switching, overload protection, and a direct indication of whether the load is on or off. They provide total system protection of equipment and wires. RPCs are designed to be located near the load and communicate control and status information remotely via low level signals of a few milliwatts. The design and operation of the RPC are considered, taking into account the operation of an RPC, the RPC power switch and drive circuits, control and trip circuits, fail-safe devices, and RPC overcurrent protection. Attention is given to the RPC development status, RPC applications, and RPC perspectives.

    Facing the pressure of fossil energy exhaustion and environment pollution, people begin to search for clean and renewable energy to partly substitute fossil energy and realize sustainable development. As the fourth type of ener-gy, biomass energy has many advantages: wide distribution, large quantity, being renewable, clean, storable and trans-portable and so on. By adopting thermo-chemical and biochemical technologies, biomass energy can be converted to high quality solid, liquid and gaseous energy products, and provide convenient heat and power energy for human being's production and daily life. This paper presented the status quo of biomass power generation industry in China and also introduced briefly the future development models.

  7. Estimated status of the power supply and demand balance in France

    International Nuclear Information System (INIS)

    The aim of the estimated status made by the energy transportation network (RTE) is to quantify the additional power generation means to put into service in the forthcoming years according to 3 reference scenarios of power consumption. These scenarios take into consideration different factors like: the growth of consumption, the energy conservation, the development of renewable energy sources, the building of the EPR reactor, the implementation of new fossil-fuel power plants, the decommissioning of old coal-fired power plants etc.. In all cases, the power generation means to be developed must be both peak-type means (combustion turbines for instance) and semi-base means (gas combined cycles for instance). These estimated needs are based on a system failure risk of 3 hours/year as an average. Finally, this status stresses on the need for specific reinforcement means of the supply security in the Provence-Alpes-Cote d'Azur (PACA) and Bretagne (Brittany) regions and also in island systems.

    At present, 232 research reactors in the world are in operation and two thirds of them have a power less than 1 MW. Many countries have used research reactors as the tools for educating and training students or engineers and for scientific service such as neutron activation analysis. As the introduction of a research reactor is considered a stepping stone for a nuclear power development program, many newcomers are considering having a low power research reactor. The IAEA has continued to provide forums for the exchange of information and experiences regarding low power research reactors. Considering these, the Agency is recently working on the preparation of a guide for the preparation of technical specification possibly for a member state to use when wanting to purchase a low power research reactor. In addition, ANS has stated that special consideration should be given to the continued national support to maintain and expand research and test reactor programs and to the efforts in identifying and addressing the future needs by working toward the development and deployment of next generation nuclear research and training facilities. Thus, more interest will be given to low power research reactors and its role as a facility for education and training. Considering these, the status of low power research reactors was reviewed, and some aspects to be considered in developing a low power research reactor were studied.

  11. Competence and the Evolutionary Origins of Status and Power in Humans.

    Science.gov (United States)

    Chapais, Bernard

    2015-06-01

    In this paper I propose an evolutionary model of human status that expands upon an earlier model proposed by Henrich and Gil-White Evolution and Human Behavior, 22,165-196 (2001). According to their model, there are two systems of status attainment in humans-"two ways to the top": the dominance route, which involves physical intimidation, a psychology of fear and hubristic pride, and provides coercive power, and the prestige route, which involves skills and knowledge (competence), a psychology of attraction to experts and authentic pride, and translates mainly into influence. The two systems would have evolved in response to different selective pressures, with attraction to experts serving a social learning function and coinciding with the evolution of cumulative culture. In this paper I argue that (1) the only one way to the top is competence because dominance itself involves competence and confers prestige, so there is no such thing as pure dominance status; (2) dominance in primates has two components: a competitive one involving physical coercion and a cooperative one involving competence-based attraction to high-ranking individuals (proto-prestige); (3) competence grants the same general type of power (dependence-based) in humans and other primates; (4) the attractiveness of high rank in primates is homologous with the admiration of experts in humans; (5) upon the evolution of cumulative culture, the attractiveness of high rank was co-opted to generate status differentials in a vast number of culturally generated domains of activity. I also discuss, in this perspective, the origins of hubristic pride, authentic pride, and nonauthoritarian leadership. PMID:25947621

  13. The status quo of China's nuclear power and the uranium gap solution

    International Nuclear Information System (INIS)

    Mainland China has eleven nuclear power reactors in commercial operation; six are under construction, and several more are slated for development in the near future. Additional reactors are planned, including some of the world's most advanced, to give a fivefold increase in nuclear capacity up to 40 GWe by 2020, and then a further three to fourfold increase to 120-160 GWe by 2030. The natural uranium supply, however, does not correspond to the speed of nuclear power development because of low production and poor deposits. After examining the existing nuclear power status quo in China, this paper provides an experimental model and a calculation method for the natural uranium needed that is based on the nuclear capacity to be installed in 2014. The natural uranium gap is further discussed through an analysis of the uranium resource distribution, reserves, and production in China, together with approaches to fill the gap. To meet the imminent uranium peak that will be required for fuel demands, China should diversify natural uranium sources and develop advanced nuclear power systems to save fuel. We kindly thank Mr. Graham Andrew, DGO, IAEA, for handing the manuscript to Mr. Chaitanyamoy Ganguly and Mr. Jan Slezak for review. We also thank Mr. Chaitanyamoy Ganguly and Mr. Jan Slezak of the IAEA for their careful reviewing of the paper and for offering very valuable comments. Many thanks also goes to Ms. Du Qingfeng for polishing the manuscript.

  14. Health status and follow-up of the Chernobyl Nuclear Power Plant accident liquidators in Latvia

    International Nuclear Information System (INIS)

    The accident at the Nuclear Power Plant in Chernobyl create a new problem for health professionals in Latvia due to the fact that 6475 inhabitants (mainly healthy and men of reproductive age) of Latvia took part in clear-up works in Chernobyl within the period 1986-1991. Chernobyl clear-up workers were exposed γ-radiation and they also incorporated radionuclides. The doses documented for the clear-up workers are variable; they are estimated to be between 0.01-0.5 Gy although the specialists working on the precision of received doses think that they could be even 2 or 3 times higher. The aim of this work is to evaluate the health status of liquidators investigating them on a long-term basis: to create the correct system of health status evaluation of Chernobyl clear-up workers, to improve the register of Chernobyl clear-up workers and of their children, to analyze the data about the incidence of different diseases and mortality gained from follow-ups, to evaluate health status and clinical picture within the period of time, to work out and use adequate methods of treatment. Chernobyl clear-up workers more often than the control group suffer from diseases of the nervous, the endocrine and the metabolic and immune system. They also have higher rate of incidence for diseases of digestive and respiratory system and for diseases of bones, muscles and connective tissue higher rates of accidents and suicides. Now, ten years after the accident there are Chernobyl clear-up workers who are chronically ill and their health status is expected to be worse in the next few years. Regular follow-up and medical examination of Chernobyl clear-up workers and their children should be carried out every year. Regular rehabilitation of Chernobyl clear-up workers should be provided by the government

  15. Nuclear power plant status diagnostics using simulated condensation: An auto-adaptive computer learning technique

    International Nuclear Information System (INIS)

    The application of artificial neural network concepts to engineering analysis involves training networks, and therefore computers, to perform pattern classification or function mapping tasks. This training process requires the near optimization of network inter-neural connections. A new method for the stochastic optimization of these interconnections is presented in this dissertation. The new approach, called simulated condensation, is applied to networks of generalized, fully interconnected, continuous preceptrons. Simulated condensation optimizes the nodal bias, gain, and output activation constants as well as the usual interconnection weights. In this work, the simulated condensation network paradigm is applied to nuclear power plant operating status recognition. A set of standard problems such as the exclusive-or problem and others are also analyzed as benchmarks for the new methodology. The objective of the nuclear power plant accidient condition diagnosis effort is to train a network to identify both safe and potentially unsafe power plant conditions based on real time plant data. The data is obtained from computer generated accident scenarios. A simulated condensation network is trained to recognize seven nuclear power plant accident conditions as well as the normal full power operating condition. These accidents include, hot and cold leg loss of coolant, control rod ejection and steam generator tube leak accidents. Twenty-seven plant process variables are used as input to the neural network. Results show the feasibility of using simulated condensation as a method for diagnosing nuclear power plant conditions. The method is general and can easily be applied to other types of plants and plant processes

  16. Present status of graphite-moderated power reactor decommissioning in foreign countries

    International Nuclear Information System (INIS)

    From 1960's on, graphite-moderated power reactors, being either of CO2 gas cooled or light water cooled type, had opened the nuclear electricity generation worldwide. Such pioneering reactors as UK Magnoxes, French GCRs, Russian AMBs had been operated for more than 20 years up to 40 years. Some of these pioneering power reactors have already been brought into permanent shutdowns, followed by decommissioning activities or preparation of decommissioning projects. On the occasion of the recent start of the decommissioning work at the Tokai Power Station, an overview on progress status in shutdown graphite-moderated power plants in several countries is given. In this report are described strategic aspects and some specific dismantling and waste management methods to be notified in individual decommissioning projects, as in the following. A few UK Magnox power stations have been in preparation for 'Safestore Construction', which will be reserved for more than 100 years after shutdown. The UKAEA's WAGR has been long undertaken as one of the big EC's reactor decommissioning projects, with extensive R and D work carried out for immediate dismantling of the graphite-moderated reactor. The recent successful progresses have revealed safe and commercial-scale dismantling procedures and technologies, which may facilitate an early dismantling shutdown nuclear facilities. The French GCR plants have been in plant-by-plant preparation for safestore for 30-40 years. The Spanish Vandellos-1 and Italian Latina plants are also under decommissioning operations similarly as in UK and France.

    Full Text Available Aim. To study psychological status and influence of antihypertensive therapy (AHT on it in Chernobyl nuclear power plant (NPP accident consequences liquidators, who suffer arterial hyper-tension (AH, with controlled treatment compared to the standard treatment in out-patient clinic. Material and methods. 81 liquidators with AH (all men were included into open compara-tive randomized study. Study duration was 12 months. Patients were randomized into main group (MG and control group (CG. Patients of MG received strictly regulated stepped AHT based on ACE inhibitor spirapril 6 mg daily (Quadropril®, Pliva-AVD, hypothiazide was added if necessary (12.5-25 mg daily and afterwards – atenolol (12.5-100 mg daily. In CG AHT and its correction was set by physician in polyclinic. Brief multifactor questionnaire for personality analysis was used to study psychological status. Results. 57 patients completed the study, 28 in MG and 29 in CG. In MG target blood pres-sure (BP levels were reached in 22 (78.6% patients, in CG – in 11 (38% patients (p<0.01. The main feature of psychological status of liquidators with AH was hypochondriac, depressive and anxious disorders. Controlled AHT made it possible to reach improvement in psychological status, i.e. growth of optimism and activity of patients, more often, than standard treatment in out-patient clinics. Increase in number of patients with pronounced anxious changes was observed in CG. Effi-ciency of AHT in liquidators with AH is connected with severity of depressive disturbances: in subgroups with inefficient treatment patients had the highest level of depression. In liquidators with AH, possessing neurotic disturbances, spirapril was efficient both as monotherapy, and in combina-tion with diuretic hydrochlorothiazide and beta-blocker atenolol. Conclusion. Controlled AHT in liquidators with AH has advantages over standard treatment in out-patient clinic and results in more frequent target BP level

  18. Reactivation of nuclear power plant construction projects. Plant status, policy issues and regulatory options

    International Nuclear Information System (INIS)

    Prior to the TMI-2 accident on March 28, 1979, four nuclear power plant units that had previously been issued a construction permit were cancelled, principally because of reduced projections of regional power demand. Since that time, an additional 31 units with CPs have been cancelled and eight units deferred. On December 23, 1985 one of the deferred units (Limerick-2) was reactivated and construction resumed. The primary objective of this policy study is to identify the principal issues requiring office-level consideration in the event of reactivation of the construction of one or more of the nuclear power plants falling into two categories: (1) LWR units issued a construction permit whose construction has been cancelled, and (2) LWR units whose construction has been deferred. The study scope is limited to identifying regulatory issues or questions deserving analysis rather than providing, at this time, answers or recommended actions. Five tasks are addressed: a tabulation and discussion of the status of all cancelled and deferred LWR units; and identification of potential safety and environmental issues; an identification of regulatory or policy issues and needed information to determine the desirability of revising certain rules and policies; and identification of regulatory options and decision criteria; and an identification of decision considerations in determining staff requirements and organizational coordination of LWR reactivation policy and implementation efforts. 41 refs

  19. Status of experiments at LLNL on high-power X-band microwave generators

    International Nuclear Information System (INIS)

    The Microwave Source Facility at the Lawrence Livermore National Laboratory (LLNL) is studying the application of induction accelerator technology to high-power microwave generators suitable for linear collider power sources. The authors report on the results of two experiments, both using the Choppertron's 11.4 GHz modulator and a 5-MeV, 1-kA induction beam. The first experimental configuration has a single traveling wave output structure designed to produce in excess of 300 MW in a single fundamental waveguide. This output structure consists of 12 individual cells, the first two incorporating de-Q-ing circuits to dampen higher order resonant modes. The second experiment studies the feasibility of enhancing beam to microwave power conversion by accelerating a modulated beam with induction cells. Referred to as the ''Reacceleration Experiment,'' this experiment consists of three traveling-wave output structures designed to produce about 125 MW per output and two induction cells located between the outputs. Status of current and planned experiments are presented

  1. Predicting the outcomes of performance error indicators on accreditation status in the nuclear power industry

    International Nuclear Information System (INIS)

    The null hypothesis for this study suggested that there was no significant difference in the types of performance error indicators between accredited and non-accredited programs on the following types of indicators: (1) number of significant event reports per unit, (2) number of forced outages per unit, (3) number of unplanned automatic scrams per unit, and (4) amount of equivalent availability per unit. A sample of 90 nuclear power plants was selected for this study. Data were summarized from two data bases maintained by the Institute of Nuclear Power Operations. Results of this study did not support the research hypothesis. There was no significant difference between the accredited and non-accredited programs on any of the four performance error indicators. The primary conclusions of this include the following: (1) The four selected performance error indicators cannot be used individually or collectively to predict accreditation status in the nuclear power industry. (2) Annual performance error indicator ratings cannot be used to determine the effects of performance-based training on plant performance. (3) The four selected performance error indicators cannot be used to measure the effect of operator job performance on plant effectiveness

    Status and future outlook of III-V compound semiconductor visible-spectrum light-emitting diodes (LEDs) are presented. Light extraction techniques are reviewed and extraction efficiencies are quantified in the 60%+ (AlGaInP) and ~80% (InGaN) regimes for state-of-the-art devices. The phosphor-based white LED concept is reviewed and recent performance discussed, showing that high-power white LEDs now approach the 100-lm/W regime. Devices employing multiple phosphors for “warm” white color temperatures (~3000 4000 K) and high color rendering (CRI > 80), which provide properties critical for many illumination applications, are discussed. Recent developments in chip design, packaging, and high current performance lead to very high luminance devices (~50 Mcd/m2 white at 1 A forward current in 1 x 1 mm2 chip) that are suitable for application to automotive forward lighting. A prognosis for future LED performance levels is considered given further improvements in internal quantum efficiency, which to date lag achievements in light extraction efficiency for InGaN LEDs.

  8. An Evaluation System for Checking the Status of I and C Systems in Nuclear Power Plants

    International Nuclear Information System (INIS)

    I and C upgrade has been hot issue around the world as progresses of degradation, aging and obsolescence have been getting worse with the continual I and C system operation, it is very difficult to develop I and C evaluation system for the real application to nuclear power plants due to complexity or reliability aspects of the methodology. Thus, to improve these problems related to evaluation and application of I and C systems, we have been developing an evaluation system which embarks an objective evaluation methodology and works on internet for convenience. This Evaluation system has been established based on the evaluation factors including system importance, performance, maintenance, aging, economic efficiency and the continuance of equipment supply, and each evaluation factor has some questionnaires which are composed of questions requiring quantitative and qualitative answers. The applied evaluation algorithm consists of scoring process among evaluation factors and weighting factor allocation process. The Evaluation system has a structure based on web environment. With this system, staffs from plant sites can directly conduct the evaluation of each I and C system status of the plant, survey of results, survey of upgrade information, and upgrade/maintenance plan. Also head office utilizes this system for the survey of the evaluation results, upgrade or maintenance plan of each site and especially acquires some useful information for making finance plans.

    Analog type I and C Systems of Nuclear Power Plants are being replaced by digital type systems because of the aging problems of the I and C systems. New NPPs have adopted computer-based digital I and C systems because the economical efficiency and the usability of the systems become higher than the analog I and C systems. However, the digital I and C systems have not been applied to NPPs because the reliability of computer systems and software has not been validated. The research works for reliability of the systems have been performed in many institutions. In this study, we reviewed the current status of I and C systems for advanced NPPs that have developed in Korea as well as in other countries until this year. We hope to use the result of this study to plan for a localization of NPP I and C systems. In this study, the I and C systems of advanced reactors such as AP600 and NUPLEX 80+ of U.S.A, CANDU 9 of Canada, APWRs and ABWRs of Japan, N4 of France, and KNGR, KALIMER, and SMART of Korea were reviewed. We reviewed the nuclear policy of U.S.A and Europe, and the NPP digital I and C systems developed in many international research institutes. Using this result, we extracted items to be researched and classified those by types of reactors. Then, we established the localization method of NPP digital I and C systems.

  10. Achieving Reduced Area and Power with Multi Bit Flip-Flop When Implemented In UART with Status Register

    Directory of Open Access Journals (Sweden)

    P.Rajeepriyanka

    2014-08-01

    Full Text Available A UART (Universal Asynchronous Receiver and Transmitter is a device allowing the reception and transmission of information, in a serial and asynchronous way. This project focuses on the implementation of UART with status register using multi bit flip-flop and comparing it with UART with status register using single bit flip-flops. During the reception of data, status register indicates parity error, framing error, overrun error and break error. The multi bit flip-flop is indicated in this status register. In modern very large scale integrated circuits, Power reduction and area reduction has become a vital design goal for sophisticated design applications. So in this project the power consumed and area occupied by both multi-bit flip-flop and single bit flip is compared. The underlying idea behind multi-bit flip-flop method is to eliminate total inverter number by sharing the inverters in the flip-flops. Based on the elimination feature of redundant inverters in merging single bit flip-flops into multi bit flip-flops, gives reduction of wired length and this result in reduction of power consumption and area.

  11. Kozloduy nuclear power plant. Units 1-4. Status of safety assessment activities. Rev. 2

    International Nuclear Information System (INIS)

    This paper presents the results of the status of safety assessment activities carried out by the Kozloduy Nuclear Power Plant (KNPP) in order to evaluate the current status of the safety of its reactor units 1-4. The steam supply system of this units is based of the reactor WWER-440/ B-230, which is a PWR of Russian design developed according to the safety standards in force in USSR in late 60-s. Now a days 10 reactor units of this type are in operation in four NPPs. Despite of efforts of the different plants to implement safety improvements measures during first 10-15 years of operation of this type of reactor its major safety problems were not eliminated and were a subject of international concern. The systematic evaluation of the deficiencies of the original design of this type of reactors have been initiated by IAEA in the beginning of 1990 and brought to developing a comprehensive list of safety problems which required urgent implementation of safety measures in all plants. To solve this problems in 1991 KNPP initiated implementation of so called 'short term' safety improvement program, developed with the help of WANO under agreement with Bulgarian Nuclear Safety Authority (BNSA) and consortium RISKAUDIT. The program was based on a stage approach and was foreseen to be implemented by tree stages in very tight time schedule in order to achieve significant and rapid improvements of the level of safety in operation of the units. The Short Tenn Program was implemented between the years 1991 and 1997 thanks of the strong safety commitment of NEK and KNPP staff and the broad international cooperation and financial support. Important part of resources were supplied under PHARE program of CEC, EBRD grant agreement and EDF support. The plant current safety level analysis has been performed using IAEA analytical methodology according to 50-SG-O12 standard 'Periodic safety review of operational nuclear power plants'. The approach and criteria for acceptable safety level

    The present situation was introduced of the geothermal power generation in Kyushu. In Kyushu, where there are lots of volcanos and abundant geothermal resources, the geothermal exploration has been made since long ago. Three non-utility use units at three geothermal power generation points and six commercial use units at five points are now in operation in Kyushu. The total output is approximately 210 MW, about 40% of the domestic geothermal power generation. At Otake and Hacchobaru geothermal power plants, the Kyushu Electric Power Company made the geothermal resource exploration through the installation/operation of power generation facilities. At the Otake power plant, a geothermal water type single flashing system was adopted first in the country because of its steam mixed with geothermal water. At the Hacchobaru power plant, adopted were a two-phase flow transportation system and a double flashing system in which the geothermal water separated from primary steam by separator is more reduced in pressure to take out secondary steam. Yamakawa, Ogiri and Takigami power plants are all for the joint exploration. Geothermal developers drill steam wells and generate steam, and the Kyushu Electric Power Company buys the steam and uses it for power generation. 5 figs., 1 tab.

    The paper reports the situation of geothermal power plants in Japan, future plans, and the research status of geothermal development technology. As for the present situation, explanations were made of each place of development covering Hokkaido to Kyushu and of each developmental organization. Since 1966 when the geothermal power plant started its commercial run, eleven plants and twelve units are presently in operation with a total approved capacity of 298,705 MW. Further, in two years six plants of 230 MW capacity are planning to start operation one by one, and a capacity of 529 MW are expected for 1996. From a viewpoint of developing domestic energy, the government set a target of geothermal supply at 600 MW in 2000 and at 2800 MW in 2010, conducting surveys for geothermal power generation, improving the subsidy system, and promoting the research development. The present target, 530 MW, is equivalent to only 0.27 % of the power generated from power plants in Japan. Geothermal energy is a valuable domestic energy, and therefore, both governmental and private efforts are being exerted for the development. 3 refs., 2 figs., 7 tabs.

  14. Status of maintenance in the US nuclear power industry 1985. Volume 2. Description of programs and practices

    International Nuclear Information System (INIS)

    This report documents a review of the status of maintenance programs and practices in the US commercial nuclear power industry. The purpose of this review is to establish a baselines reference for evaluating the effectiveness of future industry activities in maintenance. Two methods used to collect progammatic data. First, a Maintenance Review Protocol was used during site visits to eight selected power plants to collect in-depth maintenance program information. Second, a Maintenance Questionnaire was filled out by NRC Resident Inspectors regarding maintenance programs at their plant. The protocol and questionnaire contained items regarding five broad categories of maintenance: (1) organization and administration, (2) facilities and equipment, (3) procedures, (4) personnel, and (5) work control. The study found that there is wide variability in industry maintenance programs. However, the industry is currently undergoing changes in maintenance practices, and adherence to INPO and NUMARC guidance in maintenance may bring about more systematically developed program practices

    The authors examined the effect of ambivalent sexism on others' perceptions of alleged-rape incidents, in which there are socioeconomic status differences between the victims and their perpetrators. The dependent variables included measures of minimizing rape, blaming the victim, excusing the perpetrator, and determining the length of the recommended sentence. The results indicated 4 noteworthy findings: First, individuals who scored high on the hostile power relation (HPR) measure tended to minimize the seriousness of rape incidents. Second, the HPR measure moderated victim blame only in the powerful-man scenario. Third, participants who scored high on the HPR measure tended to believe that the alleged rapist held less responsibility. Fourth, female participants tended to give longer sentences.

  16. Development status of nuclear power in China and fundamental research progress on PWR primary water chemistry in China

    International Nuclear Information System (INIS)

    China's non-fossil fuels are expected to reach 20% in primary energy ratio by 2030. It is urgent for China to speed up the development of nuclear power to increase energy supply, reduce gas emissions and optimize resource allocation. Chinese government slowed down the approval of new nuclear power plant (NPP) projects after Fukushima accident in 2011. At the end of 2012, the State Council approved the nuclear safety program and adjusted long-term nuclear power development plan (2011-2020), the new NPP's projects have been restarted. In June 2015, there are 23 operating units in mainland in China with total installed capacity of about 21.386 GWe; another 26 units are under construction with total installed capacity of 28.5 GWe. The main type of reactors in operation and under construction in China is pressurized water reactor (PWR), including the first AP1000 NPPs in the world (units 1 in Sanmen) and China self-developed Hualong one NPPs (units 5 and 6 in Fuqing). Currently, China's nuclear power development is facing historic opportunities and also a series of challenges. One of the most important is the safety and economy of nuclear power. The optimization of primary water chemistry is one of the most effective ways to minimize radiation field, mitigate material degradation and maintain fuel performance in PWR NPPs, which is also a preferred path to achieve both safety and economy for operating NPPs. In recent years, an increased attention has been paid to fundamental research and engineering application of PWR primary water chemistry in China. The present talk mainly consists of four parts: (1) development status of China's nuclear power industry; (2) safety of nuclear power and operating water chemistry; (3) fundamental research progress on Zn-injected water chemistry in China; (4) summary and future.

    The security of electricity supply in Europe can only be assured by a well-balanced energy mix. To ensure the increasing amount of stochastic renewable sources like e.g. wind and solar power, economically competitive coal- and gas-fired power stations are needed. Nevertheless, currently more and more projects are stopped and postponed. In that context questions like: What is the background? What is the current situation? What should be? What are the causes? What is needed? are discussed. (orig.)

    Voluntary consumer decisions to purchase electricity supplied by renewable energy sources represent a powerful market support mechanism for renewable energy development. Beginning in the early 1990s, a small number of U.S. utilities began offering ''green power'' options to their customers. Since then, these products have become more prevalent, both from traditional utilities and from marketers operating in states that have introduced competition into their retail electricity markets. Today, more than half of all U.S. consumers have an option to purchase some type of green power product from a retail electricity provider. Currently, more than 600 utilities, or about 20% of utilities nationally, offer green power programs to customers. These programs allow customers to purchase some portion of their power supply as renewable energy--almost always at a higher price--or to contribute funds for the utility to invest in renewable energy development. The term ''green pricing'' is typically used to refer to these utility programs offered in regulated or noncompetitive electricity markets. This report documents green power marketing activities and trends in the United States.

    1999-08-01

    Nuclear power plants in Japan have been fabricated and constructed in compliance with the standards developed by MITI in 1980. These standards were developed as design standards taking aging phenomena during service lifetime into consideration. But these standards do not specify the requirements for flaw evaluation and repair methods, though they include some maintenance requirements. Therefore, MITI decided to develop Maintenance Standards which commensurate with plant age, and entrusted Japan Power Engineering and Inspection Corporation (JAPEIC) with survey of ASME Sec. XI. Draft of Maintenance Standards was developed in March, 1996, and will be legislated by 1999. Structural materials of nuclear power plants would sustain damage owing to cyclic stress, high temperature or neutron irradiation etc. during operation. And damage would change mechanical properties of materials, such as tensile strength, charpy absorption energy, fracture toughness and so on. As integrity of nuclear power station depends on these mechanical properties of materials, it will become very important to be able to evaluate mechanical properties of materials nondestructively especially for older nuclear power plants. These circumstances made MITI entrust JAPEC with verification test to develop nondestructive characterization methods. This verification test started in the 1990 fiscal year and was completed in 1997 fiscal year. (orig./DGE)

  5. Status and potential of small and medium power reactors in Pakistan

    International Nuclear Information System (INIS)

    Pakistan's interest in nuclear technology dates back to the late 1950s, when Pakistan Atomic Energy Commission (PAEC) was established with the responsibility of promoting peaceful uses of nuclear technology for the development of national economy. A beginning was made in the field of nuclear power generation by commissioning the 137 MW Karachi Nuclear Power Plant (KANUPP) in 1971. In addition to KANUPP, the other activities during this period included studies for nuclear power and sea water desalination in the coastal areas. This was followed by a series of feasibility and long term planning studies (1969-1981) to study and firm up the prospects of nuclear power in the country, using the ever-improving analytical tools and data base. An Energy and Nuclear Power Planning Study for Pakistan has just been completed as a technical cooperation project of the IAEA to provide a sound basis for the formulation of the strategy for future development of nuclear power. The successful functioning of KANUPP and the 300 MW NPP (CHASNUPP) presently being built by China have given the country great confidence and a sense of direction to plan more nuclear units in future, in the S and MR range, in a manner that would progressively lead to a high degree of self-reliance. A large number of studies have been carried out in the past all over the world to investigate the possibility of using nuclear generated heat for the purpose of desalting seawater. It is now proposed that IAEA may initiate a programme to install an International Demonstration Nuclear Desalination Plant (IDNDP) in some developing country to provide hands on experience in this field.

  6. Status of the upgraded version of the NRL GAMBLE II pulse power generator

    International Nuclear Information System (INIS)

    The GAMBLE II water dielectric pulse power generator, in 1970, was the forerunner of the high energy (> 50 kJ) class of water dielectric generators. It has been redesigned internally to make maximum use of its original outer conductor shell and to optimize it for the positive polarity mode of operation for positive ion beam experimentation. The new design also initiates the use of an oil dielectric multi-channel switch at the output of the pulse forming line. This switch, because of its low capacitance, eliminates the need for an extra prepulse switch. The upgraded version has been tested up to power and energy levels which are nearly twice the original

  7. Present status of geological and geophysical work at selected nuclear power plant sites in Czechoslovakia

    International Nuclear Information System (INIS)

    In the last three years geological methods were used in Czechoslovakia to study several potential and approved sites for the construction of nuclear power plants. In the Blahutovice locality (northern Moravia) large-scale geophysical measurements have been carried out since 1982 whose objective is to identify microbumps and to determine their foci in the surrounds of the future nuclear power plant construction site. Similar measurements are being prepared for other localities, namely in eastern Bohemia and in Kecerovce in eastern Slovakia. In other localities changes in the intensity of earthquakes are studied caused by the detailed geological and hydrogeological situation. (Z.M.)

    Full Text Available Municipal solid waste (MSW is an important energy resource for combined heat and power (CHP production. This study summarized an overview of CHP by MSW to energy (WtE plants in South Korea and discussed the issues related to energy efficiency improvement. Given the dominant housing culture of apartment living in South Korea, the primary energy output of WtE plants has been for district heating. In 2010, approximately half of the 51 large WtE plants were CHP, while the rest produced heat. Power generation in the WtE CHP plants was estimated to be only 3.65% of the thermal input, while heat production was 60.79%. The R1 efficiency when compared to that in Europe was similar for the CHP plants and higher for heat-only plants. Improving power generation efficiency is required for new power plants producing steam at pressures higher than the current level of 20–30 bar. Over ten of the existing plants needed to increase their energy efficiency by installing new equipment such as steam turbines for excess steam. Finally, transboundary centralization of WtE plants between neighboring local authorities is essential for heat utilization since many existing small-scale plants (<50 t/day capacity do not recover heat.

    Institute for Unmanned Space Experiment Free Flyer (USEF) and Mitsubishi Electric Corporation (MELCO) are developing the next generation ion engine system under the sponsorship of Ministry of Economy, Trade and Industry (METI) within six years. The system requirement specifications are a thrust level of over 250mN and specific impulse of over 1500 sec with a less than 5kW electric power supply, and a lifetime of over 3,000 hours. These target specifications required the development of both a Hall Thruster and a Power Processing Unit (PPU). In the 2007 fiscal year, the PPU called Second Engineering Model (EM2) consist of all power supplies was a model for the Hall Thruster system. The EM2 PPU showed the discharge efficiency was over 96.2% for 250V and 350V at output power between 1.8kW to 4.5kW. And also the Hall Thruster could start up quickly and smoothly to control the discharge voltage, the inner magnet current, the outer magnet current and the xenon flow rate.

    Six years ago, M-C Power (MCP) developed a comprehensive business plan to commercialize molten carbonate fuel cell (MCFC) power plants. On an annual basis the plan has been reviewed and modified to adapt to identified end user needs and technological advancements. As a result, product definition kept abreast with marketing requirements. Over the last five years, there was order and reason for subtle shifts in supply, demand, competition and pricing policies. Today, however, traditional market assessment assumptions must be challenged. There is a revolution taking place. The revolution can be summed up in one word ... deregulation. Deregulation of the airline industry led to consideration of the natural gas industry. Now that natural gas deregulation is behind us, it is electric power and telecommunications that are receiving attention. Increased emphasis is being placed on achieving market-priced power. The net result will be thinner margins for the seller and the end user. What does this mean for the commercialization of molten carbonate fuel cells?

  14. Nuclear power in the world. Its present status and development trends

    International Nuclear Information System (INIS)

    A summary of the most important data about the nuclear power reactors in operation and under construction as of the end of 1993 is given: their capacity, share of world capacity, growth of nuclear electricity generation since 1970 and its distribution by country. Nuclear prospects in the medium (2015) and long term (2025) are connected with a broad range of factors: development of advanced reactors ensuring high level of safety, implementation of high level waste repositories, enhancing the public acceptance of nuclear power. The issue of the cost of electricity generation is also discussed. Nuclear capacity projections to 2015 by region are given with 'low' and 'high' estimates. The low case reflects the continuation of the present trend of stagnation in nuclear power development due to public opposition and low economic growth in OECD countries, uncertainties in Eastern Europe and lack of finding in developing countries. The high case reflects a moderate revival of nuclear power development in the light of a more comprehensive assessment of the macro-economic and environmental aspects of the different options available for electricity generation. 7 figs., 5 tabs.

    2011-12-01

    Electroactive polymer artificial muscle (EPAM), known collectively as dielectric elastomers in the literature, has been shown to offer unique capabilities as an actuator and is now being developed for a wide variety of generator applications. EPAM has several characteristics that make it potentially well suited for wave, water current, wind, human motion, and other environmental energy harvesting systems including a high energy density allowing for minimal EPAM material quantities, high energy conversion efficiency independent of frequency of operation and non-toxic and low-cost materials not susceptible to corrosion. Experiments have been performed on push-button and heel-mounted generator devices powered by human motion, ocean wave power harvesters mounted on buoys and water turbines. While the power output levels of such demonstration devices is small, the performance of these devices has supported the potential benefits of EPAM. For example, an electrical energy conversion efficiency of over 70% was achieved with small wave heights. The ability of EPAM to produce hydrogen fuel for energy storage was also demonstrated. Because the energy conversion principle of EPAM is capacitive in nature, the performance is largely independent of size and it should eventually be possible to scale up EPAM generators to the megawatt level to address a variety of electrical power needs.

    International Nuclear Information System (INIS)

    This report presents the findings, conclusions and recommendations derived from activities performed under Phase I of the NRC Maintenance and Surveillance Program (MSP). Findings are based on trends and patterns derived from operational data compiled by the NRC for the period 1980 through 1985, site surveys conducted at eight plants, and questionnaires administered to NRC Resident Inspectors to characterize nuclear power plant maintenance programs and practices. These activities have shown that plant maintenance programs and practices are highly variable from plant-to-plant and are currently undergoing major changes. While measured plant performance has improved overall since 1980, the maintenance-related contribution to reportable events and challenges to safety systems remains high and is increasing by some measures. The findings of Phase I of the MSP confirmed a number of problems in nuclear power plant maintenance which warrant further NRC and industry attention

    A present Japanese national project for SMES development focuses on the development of cost reduction technologies for a small-scale SMES for power system control. Optimal SMES system concepts were developed for power system stabilization and for load fluctuation compensation or frequency regulation. Performance of the designed superconductors was analyzed through fabrication and tests of short sample superconductors. Then, two kinds of model coil systems were manufactured and tested for evaluation of the design concepts and cost reduction technology developments. A multi-pole solenoid coil set as a model coil system for load fluctuation compensation SMES was successfully tested, for example, in 10 000-pulse iterative charge-discharge operations. In addition, application of high-T{sub C} superconductors to SMES has been studied for further cost reduction, more reliable operation, etc.

    NASA-Lewis and other U.S. Government agencies have supported experimental and analytical programs for the characterization of Stirling cycle engines' thermodynamic losses, with a view to the improvement of Stirling engine design capabilities. The Space Power Demonstrator Engine is noted to have benefited from these efforts; test data and model predictions suggest that even greater performance improvements would be obtainable through additional modifications of engine regenerator and heater hardware.

    Coated particle fuel has been proposed recently for use in Radioisotope Power Systems (RPSs) and Radioisotope Heater Units (RHUs) for a variety of space missions requiring power levels from mWs to 10's or even hundreds of Watts. It can be made into different shapes and sizes of solid compacts, heating tapes, or paints. Using a conservative design approach, this fuel form could increase by 2.3-2.4 times the thermal power output of a LWRHU, while offering promise of enhanced safety. These performance figures are based on using single-size (500 μm) compacts of ZrC coated 238PuO2 kernels and assuming 10% and 5% He release, respectively, at 1723 K, following 10 years of storage. Using binary-size (300 and 1200 μm) fuel kernels in the compact increases the thermal power output by an additional 15%. 238PuO2 fuel kernels are intentionally sized (>=300 μm in diameter) to prevent any adverse radiological effects. They are non-respirable and non-inhalable and, if ingested, would simply be excreted with no radiological effects. The 238PuO2 fuel kernels are contained within a strong ZrC coating, which is designed to fully retain the fuel and the helium gas. Helium retention in large grain (>=300 μm) granular and polycrystalline fuel kernels is possible even at high temperatures (>1700 K). The former could be fabricated using binderless agglomeration or similar processes, while the latter could be fabricated using Sol-Gel or thermal plasma processes, with potentially less radioactive waste and fabrication contamination. In addition to summarizing the results of a recent effort investigating the performance of coated fuel particle compact (CPFC) and helium gas release, this paper identifies and discusses future research and testing needs. .

    The major trends in development of protective relaying and automatic control devices for electric power systems are toward more intricate algorithms of operation, higher response speed and higher reliability, the latter achieved by means of build-in monitoring devices and by automatic checking, all this being aimed at reducing the cost of maintenance of station and distribution equipment. The need for more intricate algorithms of control and relaying arises from the fact that the difference between anomalous and normal conditions is becoming smaller, while at the same time the power ratings and the costs of electrical power equipment are increasing. Plans for the coming 12th five-year-plan period include a new generation of automatic protective relays with extensive use of integrated microcircuits, to serve overhead transmission lines of 500 kV and higher voltage classes, with inclusion of microcomputers and microprocessors for solving diverse problems of automatic control, with inclusion of self-checking means, with the possibility of incorporation into hierarchical dispatch and fault anticipation systems, with better performance characteristics such as speed and precision, also with simpler means of fault analysis and fault data transmission. Replacement of analog relaying techniques with digital ones will greatly contribute to the realization of these goals.

  7. Status report on the conceivable outside pressure exerted on nuclear power stations by gaseous explosions

    International Nuclear Information System (INIS)

    The following incidents to be taken into account in the whole process beginning with gas release and ending with a possible stress exerted on the power plant building are discussed in detail: Conditions leading to the release of large amounts of gas; formation of an explorable gas mixture cloud; ignition and course of explosion; pressure wave propagation in the surrounding air; construction dynamics and damaging effects. Experimental results obtainable so far and analyses of large explosions are discussed with a view to their consequences. Special emphasis is placed on the question as to whether extremely unfavourable conditions may lead to a detonation of the cloud instead of a deflagration. Considering the physical laws of cloud formation and the special initiation conditions governing free gas-air-mixtures as a result of gas dynamics and reaction kinetics it can be concluded that a detonation seems to be very unlikely. It is examined what kind of studies are still to be canied out in order to clarity the question of a possible detonation. On the other hand, it is not yet possible to give a decisive answer to the question of whether and to what extent nuclear power plants are endangered by gas cloud deflagration. Due to the complex wave field resulting from diffraction and reflexion of the incoming pressure wave by the buildings of the nuclear power station, a variety of stress functions are possible that may, under certain circumstances, lead to a selective excitation of single vibration modes of the structure.

    2015-06-01

    Full Text Available The depletion of the conventional energy sources, as well as the degradation and pollution of the environment by the exploitation of fossil fuels caused the development of renewable energy sources (RES, including biomass. In Poland, biomass is the most popular renewable energy source, which is closely related to the obligations associated with the membership in the EU. Biomass is the oldest renewable energy source, and its potential, diversity and polymorphism place it over other sources. Besides, the improvement in its parameters, including an increase in its calorific value, resulted in increasing use of biomass as energy source. In the electric power industry biomass is applied in the process of co-combustion with coal. This process may contribute, inter alia, to the reduction in the emissions of carbon, nitrogen and sulfur oxides. The article presents the characteristics of the biomass burned in power boilers of one of the largest Polish power plants, located in Opole Province (Southern Poland. Besides, the impact of biomass on the installation of co-combustion, as well as the advantages and disadvantages of the co-combustion process not only in technological, but also environmental, economic and social aspects were described.

  9. Long-term and hopeful power source development and nuclear power generation in Japan. A survey on future status of the nuclear power generation

    International Nuclear Information System (INIS)

    As an evaluation point of introduction of the nuclear power generation, not only its economics but only its earth-warming problem, energy security and so forth can be thought as its plus side. In this report, for a side of 'Energy security' and 'Uncertain cost effectiveness in future' with a particularly less chance of quantitative evaluation among these diverse evaluation points till now, a consideration of positioning of the nuclear power generation was executed from a viewpoint of what source construction was subjectively preferable on considering the cost in a broad sense in future (AD 2030) of Japan. As a result, when considering of 'Supply cessation of LNG and the earth warming' and 'Uncertainty of electric power demand in future', the significance of existence of the nuclear power could be evaluated by about 10% higher share from its point of economics than that of without its consideration. And, 'Security' could also be discussed on a meaning of 'Quantitative evaluation of a specified factor' acting as a model, from a different standpoint of 'Supply cessation of LNG' and 'Response to the future certainty' given an attention to factor of 'Supply security' given only little quantitative evaluation till now.

    Full Text Available The aim of this study was to investigate maximum aerobic power (VO2 max and anaerobic threshold (AT as determinants of training status among professional soccer players. Twelve professional 1st team British male soccer players (age: 26.2 ± 3.3 years, height: 1.77 ± 0.05 m, body mass: 79.3 ± 9.4 kg agreed to participate in the study and provided informed consent. All subjects completed a combined test of anaerobic threshold (AT and maximum aerobic power on two occasions: Test 1 following 5 weeks of low level activity at the end of the off-season and Test 2 immediately following conclusion of the competitive season. AT was assessed as both lactate threshold (LT and ventilatory threshold (VT. There was no change in VO2 max between Test 1 and Test 2 (63.3 ± 5.8 ml·kg-1·min-1 vs. 62.1 ± 4.9 ml·kg-1·min-1 respectively, however, the duration of exercise tolerance (ET at VO2 max was significantly extended from Test 1 to Test 2 (204 ± 54 vs. 228 ± 68 s respectively (P<0.01. LT oxygen consumption was significantly improved in Test 2 versus Test 1 (P<0.01 VT was also improved (P<0.05. There was no significant difference in VO2 (ml·kg-1·min-1 corresponding to LT and VT. The results of this study show that VO2 max is a less sensitive indicator to changes in training status in professional soccer players than either LT or VT.

  11. Current status of life management policies for nuclear power plants in Japan

    International Nuclear Information System (INIS)

    Because of growing public interest and concern on increasing aged nuclear plants in near future, the importance of measures against the aging nuclear plants was pointed out. In April 1996, the Ministry of International Trade and Industry (MITI) published the first report regarding the measures to cope with the aged nuclear power plants. The report summarizes the results of studies of technical evaluation of the aged nuclear power plants and the measures to address the aged plants. The power plants evaluated are two BWR units and one PWR unit. The first phase evaluations were focused on the major components and structures such as the reactor pressure vessels and core internals which are important for safety and are not easily repaired or replaced (Part 1 Evaluation). In the second phase, utility companies have carried out the technical evaluations not only for the major components and structures but also for all the components and structures of the plants, and the results are now under review by the government (Part 2 Evaluation). In the report, the technical evaluation concluded that with correct and adequate maintenance, safe operation is possible despite operation having exceeded 30 years. Regarding the measures, the direction to enhancement of periodical inspections and establishment of structural standards in response to the plant aging was indicated. Focused on the maintenance activities by the utilities, the report also indicates that it is important for the utilities to establish the appropriate long-term maintenance program. The report also indicated the technology development items toward attaining further highly reliable management. (author)

    Degradation of the cable jacket, electrical insulation, and other cable components of installed cables within nuclear power plants (NPPs) is known to occur as a function of age, temperature, radiation, and other environmental factors. System tests verify cable function under normal loads; however, the concern is over cable performance under exceptional loads associated with design-basis events (DBEs). The cable's ability to perform safely over the initial 40-year planned and licensed life has generally been demonstrated and there have been very few age-related cable failures. With greater than 1000 km of power, control, instrumentation, and other cables typically found in an NPP, replacing all the cables would be a severe cost burden. Justification for life extension to 60 and 80 years requires a cable aging management program to justify cable performance under normal operation as well as accident conditions. Currently the gold standard for determining cable insulation degradation is the elongation-at-break (EAB). This, however, is an ex-situ measurement and requires removal of a sample for laboratory investigation. A reliable nondestructive examination (NDE) in-situ approach is desirable to objectively determine the suitability of the cable for service. A variety of tests are available to assess various aspects of electrical and mechanical cable performance, but none of these tests are suitable for all cable configurations nor does any single test confirm all features of interest. Nevertheless, the complete collection of test possibilities offers a powerful range of tools to assure the integrity of critical cables. Licensees and regulators have settled on a practical program to justify continued operation based on condition monitoring of a lead sample set of cables where test data is tracked in a database and the required test data are continually adjusted based on plant and fleet-wide experience.

  17. Analysis of the Concept and Implementation Status of Performance Based Regulation for Nuclear Power Plants

    International Nuclear Information System (INIS)

    To have better understanding of performance based regulation, the concept of performance based regulation, its advantages and disadvantages, and implementation status have been analyzed. The results are described herein. Also, the success conditions to implement the approach are presented. Performance based regulation is one of useful regulatory approaches. It will contribute to the enhancement of nuclear regulatory system's effectiveness and efficiency. Examples include improving the objectivity and transparency of regulatory decision-making, promoting licensee flexibility in response to regulatory requirements that can reduce licensee burden, and promoting safety by focusing achievement of performance goal. To implement it successfully, there are some conditions to be satisfied as follows; · sufficient understanding of the concept of performance based regulation, · combination with risk-informed regulation to create synergy effect, · sufficient communication between regulators and regulated entities prior to implement it, · production and maintenance of reliable performance data by the regulated entities, and · social consensus on performance based regulation. Also, expanding use of performance based regulation will be helpful to the effective regulatory source management and the promotion of voluntary safety activities

  18. Present status of research activities in severe accident evaluation for nuclear power plants

    International Nuclear Information System (INIS)

    The basis for securing nuclear safety is to prevent occurrence of accidents and to mitigate propagation of abnormal events or accidents to severe accidents. In practice, a nuclear power plant is designed and constructed so that abnormal events can be detected at the early phase to cope with the events and safety features and facilities are installed to mitigate and reduce the consequences in the case of such accidents. However it is important to prepare preventive measures as well as mitigative measures to cope with severe accidents to further improve the level of safety. Research on the evaluation of severe accidents is needed to develop such measures. Severe accident research is performed in many countries including Japan and a lot of findings have been made. At JAERI, experiments are being conducted to clarify severe accident phenomena and to make quantitative evaluation of safety margin of a nuclear power plant against severe accidents. A lot of findings on the fuel damage process in the early phase of severe accidents have been obtained in the past years. However there are still large uncertainties on the fuel damage process in the late phase of accidents. In the area of accident management, there exists need for experiments and analyses. (author)

  19. Radiological environmental monitoring programs at nuclear power plants: A status report

    International Nuclear Information System (INIS)

    This paper addresses the content and conduct of radiological environmental monitoring programs (REMPs) conducted at nuclear power plants. Such programs have, since their inception, played a key role in assessing the open-quotes bottom lineclose quotes of a plant's impact on its environment. They are the principal means by which the actual impact of monitored and unmonitored effluent pathways can be integrated in the form of a bounding dose to the human population in the plant's environs. NRC regulations generally prescribe only that effluent and environmental monitoring programs appropriate to the licensed activity be established and conducted. Detailed guidance for such programs is contained in Regulatory Guides, Branch Technical Positions, and staff reports (NUREGs). Agency guidance, which is summarized in the paper, has continued to focus on principal radiation exposure pathways to the general public associated with effluents arising from normal operation, as well as anticipated operational occurrences. Through the Technical Specifications Improvement Program, licensees are now allowed some flexibility with respect to modification of certain program details, provided that certain regulatory constraints continue to be met, Sample results for six environmental media for 15 U.S. commercial nuclear power plants for the period 1986-94 are summarized in the paper. Based on a comparison of indicator and control locations, no significant impacts were noted in the form of radionuclide concentrations of plant origin

    Today Spain is still the worldwide leader in the use of Concentrating Solar Power (CSP) technology with more than 2300 MW installed solar thermal power rated in 2015, compared to the 4600 MW installed worldwide. In order to improve the quality of current plants and require the best quality for future plants, the subcommittee SC 117 "Thermoelectric Solar Energy Systems", which is part of the committee AEN/CTN 206 for electricity production, works on different aspects of the plants since 2010. This paper gives an overview of the state of the publications in draft to qualify the performance and the durability of the main components of the solar field (receiver tubes, solar tracking systems, reflectors, heat transfer fluids, collectors and specific sensors). A summary of the main tests set for each component in the future Spanish standards is presented. The first complete standard drafts will be ready by the end of the current year 2015 and most are expected to be published within the following years.

  1. Local status and power in area-based health improvement partnerships.

    Powell, Katie; Thurston, Miranda; Bloyce, Daniel

    2014-11-01

    Area-based initiatives have formed an important part of public policy towards more socio-economically deprived areas in many countries. Co-ordinating service provision within and across sectors has been a common feature of these initiatives. Despite sustained policy interest in area-based initiatives, little empirical work has explored relations between area-based initiative providers, and partnership development within this context remains under-theorised. This article addresses both of these gaps by exploring partnerships as a social and developmental process, drawing on concepts from figurational sociology to explain how provider relations develop within an area-based initiative. Qualitative methods were used to explore, prospectively, the development of an area-based initiative targeted at a town in the north west of England. A central finding was that although effective delivery of area-based initiatives is premised on a high level of co-ordination between service providers, the pattern of interdependencies between providers limits the frequency and effectiveness of co-operation. In particular, the interdependency of area-based initiative providers with others in their organisation (what is termed here as 'organisational pull') constrained the ways in which they worked with providers outside of their own organisations. 'Local' status, which could be earned over time, enabled some providers to exert greater control over the way in which provider relations developed during the course of the initiative. These findings demonstrate how historically constituted social networks, within which all providers are embedded, shape partnership development. The theoretical insight developed here suggests a need for more realistic expectations among policymakers about how and to what extent provider partnerships can be managed. PMID:24695385

  2. Status of GT-MHR with emphasis on the power conversion system

    International Nuclear Information System (INIS)

    The conceptual design of the Gas Turbine-Modular Helium Reactor (GT-MHR) has made significant progress in the past year. Evaluation of an external versus internal (submerged) generator and modifications as a result of an internal seal task force were completed. Significant progress was also made on the design of the generator utilizing existing technology. Conceptual design of the turbocompressor was confirmed, including extensive evaluation of the entire turbomachine (turbocompressor and generator) rotor dynamics. Results concluded in a revised configuration for the location of magnetic bearings supporting the entire machine. Integration of the turbomachine with the recuperator, precooler, intercooler and internal ducts and seals progressed to improved maintenance and operation. This resulted in some changes and improvements in the overall arrangement of the power conversion module. The paper also provides a summary of the fuel and safety assessment progress.

    Morris, Lynnae Carol

    The purpose of this research has been to determine the influence of verbal and nonverbal behavior on power and status within small groups. The interactions which took place within five small groups of students in a middle school spatial reasoning elective were analyzed. Verbal responses to requests for help were analyzed using sequential analysis techniques. Results indicated that the identity of the student asking a question or requesting help in some form or another is a better predictor of whether he/she will receive help than the type of questions he/she asks. Nonverbal behavior was analyzed for social gestures, body language, and shifts in possession of tools. Each nonverbal act was coded as either "positive" (encouraging participation) or "negative" (discouraging participation); and, the researchers found that in groups in which there was unequal participation and less "help" provided among peers (according to the verbal analysis results) there tended to be more "negative" nonverbal behavior demonstrated than in groups in which "shared talk time" and "helping behavior" were common characteristics of the norm. The combined results from the analyses of the verbal and nonverbal behavior of students within small groups were then reviewed through the conflict, power, status perspective of small group interactions in order to determine some common characteristics of high functioning (collaborative) and low functioning (non-collaborative) groups. Some common characteristics of the higher functioning groups include: few instances of conflict, shared "talk time" and decision making, inclusive leadership, frequent use of encouraging social gestures and body language, and more sharing of tools than seizing. Some shared traits among the lower functioning groups include: frequent occurrences of interpersonal conflict, a focus on process (rather than content), persuasive or alienating leadership, unequal participation and power, frequent use of discouraging social gestures

    In Asia, there are many institutes for the R&D of high power laser science and applications. They are 5 major institutes in Japan, 4 major institutes in China, 2 institutes in Korea, and 3 institutes in India. The recent achievements and future prospects of those institutes will be over viewed. In the laser fusion research, the FIREX-I project in Japan has been progressing. The 10kJ short pulse LFEX laser has completed and started the experiments with a single beam. About 1kJ pulse energy will be injected into a cone target. The experimental results of the FIREX experiments will be presented. As the target design for the experiments, a new target, namely, a double cone target was proposed, in which the high energy electrons are well confined and the heating efficiency is significantly improved. Together with the fusion experiments, Osaka University has carried out laboratory astrophysics experiments on photo ionizing plasmas to observe a unique X-ray spectrum from non-LTE plasmas. In 2008, Osaka university has started a new Photon research center in relation with the new program: Consortium for Photon Science and Technology: C-PhoST, in which ultra intense laser plasmas research and related education will be carried out for 10 years. At APRI, JAEA, the fundamental science on the relativistic laser plasmas and the applications of laser particle acceleration has been developed. The application of laser ion acceleration has been investigated on the beam cancer therapy since 2007. In China, The high power glass laser: Shenguan-II and a peta watt beam have been operated to work on radiation hydro dynamics at SIOFM Shanghai. The laser material and optics are developed at SIOFM and LFRC. The IAPCM and the IOP continued the studies on radiation hydrodynamics and on relativistic laser plasmas interactions. At LFRC in China, the construction of Shenguan III glass laser of 200kJ in blue has progressed and will be completed in 2012. Together with the Korean program, I will

    2016-01-01

    NASA Glenn Research Center (GRC) is developing fission power system technology for future Lunar and Martian surface power applications. The systems are envisioned in the 10 to 100kWe range and have an anticipated design life of 8 to 15 years with no maintenance. NASA GRC is currently setting up a 55 kWe non-nuclear system ground test in thermal-vacuum to validate technologies required to transfer reactor heat, convert the heat into electricity, reject waste heat, process the electrical output, and demonstrate overall system performance. The paper reports on the development of the heat pipe radiator to reject the waste heat from the Stirling convertors. Reducing the radiator mass, size, and cost is essential to the success of the program. To meet these goals, Advanced Cooling Technologies, Inc. (ACT) and Vanguard Space Technologies, Inc. (VST) are developing a single facesheet radiator with heat pipes directly bonded to the facesheet. The facesheet material is a graphite fiber reinforced composite (GFRC) and the heat pipes are titanium/water Variable Conductance Heat Pipes (VCHPs). By directly bonding a single facesheet to the heat pipes, several heavy and expensive components can be eliminated from the traditional radiator design such as, POCO"TM" foam saddles, aluminum honeycomb, and a second facesheet. As mentioned in previous papers by the authors, the final design of the waste heat radiator is described as being modular with independent GFRC panels for each heat pipe. The present paper reports on test results for a single radiator module as well as a radiator cluster consisting of eight integral modules. These tests were carried out in both ambient and vacuum conditions. While the vacuum testing of the single radiator module was performed in the ACT's vacuum chamber, the vacuum testing of the eight heat pipe radiator cluster took place in NASA GRC's vacuum chamber to accommodate the larger size of the cluster. The results for both articles show good agreement

  6. The status of the Canadian nuclear power program and possible future strategies

    International Nuclear Information System (INIS)

    Canada is fortunate in having developed a versatile and flexible power reactor concept-one which can be kept economically competitive into the distant future, while at the same time offering opportunities for large reductions in uranium requirements. The one CANDU concept provides a range of alternatives, at least as extensive in terms of adaptation to changing economic and uranium supply conditions as that of most other nuclear power programs consisting of two or more distinct reactor types. The range includes reduced capital costs through use of boiling light water and organic cooled options, better thermal efficiency through use of the organic cooled option, and the ability to minimize the impact of changing economic parameters and improve uranium utilization through use of Pu recycle and/or thorium fuel with uranium recycle. AECL has devoted considerable effort over the last few years to study of advanced fuel cycles in the various CANDU reactor types. Very few feasibility questions have been uncovered. A detailed conceptual study of our currently favoured vehicle for Pu recycle, CANDU-BLW (PB), a plutonium burning, boiling light water cooled CANDU, has indicated that it could be initiated with no major problems. Development would be required in a number of areas-notably, fuel design and computational methods for fuel management. The results indicate a savings of some 15-20% in plant capital costs over the natural uranium CANDU-PHW and a reduction of almost a factor of two in uranium requirements. More general studies of thorium fuelled concepts are also encouraging. The reactor designs are almost identical to those for uranium CANDU reactors and so no new feasibility problems are introduced. We recognize feasibility problems associated with specific fuels in specific CANDU types, but there appear to be none in the areas of reactor physics, control, safety and fuel management. These concepts are competitive with CANDU-PHWs even for current economic conditions

  7. The Status of Research Regarding Magnetic Mirrors as a Fusion Neutron Source or Power Plant

    Energy Technology Data Exchange (ETDEWEB)

    Simonen, T

    2008-12-23

    Experimental results, theory and innovative ideas now point with increased confidence to the possibility of a Gas Dynamic Trap (GDT) neutron source which would be on the path to an attractively simple Axisymmetric Tandem Mirror (ATM) power plant. Although magnetic mirror research was terminated in the US 20 years ago, experiments continued in Japan (Gamma 10) and Russia (GDT), with a very small US effort. This research has now yielded data, increased understanding, and generated ideas resulting in the new concepts described here. Early mirror research was carried out with circular axisymmetric magnets. These plasmas were MHD unstable due to the unfavorable magnetic curvature near the mid-plane. Then the minimum-B concept emerged in which the field line curvature was everywhere favorable and the plasma was situated in a MHD stable magnetic well (70% average beta in 2XII-B). The Ioffe-bar or baseball-coil became the standard for over 40 years. In the 1980's, driven by success with minimum-B stabilization and the control of ion cyclotron instabilities in PR6 and 2XII-B, mirrors were viewed as a potentially attractive concept with near-term advantages as a lower Q neutron source for applications such as a hybrid fission fuel factory or toxic waste burner. However there are down sides to the minimum-B geometry: coil construction is complex; restraining magnetic forces limit field strength and mirror ratios. Furthermore, the magnetic field lines have geodesic curvature which introduces resonant and neoclassical radial transport as observed in early tandem mirror experiments. So what now leads us to think that simple axisymmetric mirror plasmas can be stable? The Russian GDT experiment achieves on-axis 60% beta by peaking of the kinetic plasma pressure near the mirror throat (where the curvature is favorable) to counter-balance the average unfavorable mid-plane curvature.

  8. The Status of Research Regarding Magnetic Mirrors as a Fusion Neutron Source or Power Plant

    International Nuclear Information System (INIS)

    Experimental results, theory and innovative ideas now point with increased confidence to the possibility of a Gas Dynamic Trap (GDT) neutron source which would be on the path to an attractively simple Axisymmetric Tandem Mirror (ATM) power plant. Although magnetic mirror research was terminated in the US 20 years ago, experiments continued in Japan (Gamma 10) and Russia (GDT), with a very small US effort. This research has now yielded data, increased understanding, and generated ideas resulting in the new concepts described here. Early mirror research was carried out with circular axisymmetric magnets. These plasmas were MHD unstable due to the unfavorable magnetic curvature near the mid-plane. Then the minimum-B concept emerged in which the field line curvature was everywhere favorable and the plasma was situated in a MHD stable magnetic well (70% average beta in 2XII-B). The Ioffe-bar or baseball-coil became the standard for over 40 years. In the 1980's, driven by success with minimum-B stabilization and the control of ion cyclotron instabilities in PR6 and 2XII-B, mirrors were viewed as a potentially attractive concept with near-term advantages as a lower Q neutron source for applications such as a hybrid fission fuel factory or toxic waste burner. However there are down sides to the minimum-B geometry: coil construction is complex; restraining magnetic forces limit field strength and mirror ratios. Furthermore, the magnetic field lines have geodesic curvature which introduces resonant and neoclassical radial transport as observed in early tandem mirror experiments. So what now leads us to think that simple axisymmetric mirror plasmas can be stable? The Russian GDT experiment achieves on-axis 60% beta by peaking of the kinetic plasma pressure near the mirror throat (where the curvature is favorable) to counter-balance the average unfavorable mid-plane curvature. Then a modest augmentation of plasma pressure in the expander results in stability. The GDT

  10. Ergonomic design of an overview display in a nuclear power plant control room. Integrated process status overview

    International Nuclear Information System (INIS)

    A major modification of the Borssele Nuclear Power Plant (NPP), scheduled in 1997, includes the installation of a new Integrated Process Status Overview (IPSO) display in the extensively modified control room. The IPSO display is to promote effective communications among all individuals present in the control room with a clear overview of the main process systems. The flexible LCD rear-projection technique is selected for the replacement of the existing IPSO display with engraved process symbols and hard-wired LEDs. The relation between the IPSO display and the CRT based Process Presentation System (PPS) is described after an elaborate introduction to the nuclear technology and the modification project. The followed IPSO design methodology includes interviews with all IPSO user groups to acquire their experience and comment on the current IPSO in order to enhance the functionality and the acceptance of the new IPSO graphics. The ergonomic design requirements for the new IPSO display concern both generic aspects of information presentation on human-machine interfaces, as well as specific issues related to the selected LCD rear-projection technique. Intermediate stages in the design of the IPSO graphics are outlined as well as the results of the concept evaluation by the user groups. For special interest the functionality of a three dimensional (3-D) display was explored. The design study concludes with a 'final' IPSO graphics design to be used for evaluations on the control room simulator. The presentation of one graphic was found to be most appropriate with adjustment of colour (grey) of components and systems which do not need to operate during the current process conditions or plant mode.

  11. Institutional framework of the Chinese power sector. Background and overview paper on the status quo and reforms of the Chinese power sector

    International Nuclear Information System (INIS)

    The Chinese power sector is currently undergoing significant structural changes. This report describes the current developments of the institutional framework of the Chinese power sector and the emerging Chinese electricity market. It is intended as a background information paper for foreign consultants and others that grapple with the complicated and fast changing structure of the Chinese power sector. The scope of this report is limited to grid-connected power. The paper starts with a brief introduction to the structure of the Chinese Government and then describes the main changes that have occurred in the Chinese power sector since 1978. Early power sector reforms consisted of decentralisation of decision making power to lower government levels, deregulation of investment and price control, and corporatization of the operational and business parts of the state electricity activities. The increasing inefficiencies of an ever more complicated and bureaucratic government, the non-transparency of policies, regulations and pricing, and the confused ownership and management structure of utility assets called for further reforms. In 1997 an episode of further institutional and market reforms was initiated aiming to achieve a fully competitive wholesale power market by 2010. The reforms started with the further separation of government and business functions that were previously combined in the same government units. Most notably the State Power Corporation (SP) was established while the former Ministry Of Electric Power (MOEP) was dissolved. The government responsibilities of MOEP were turned over to the State Economic and Trade Commission (SETC). Near-term power sector reforms will concentrate on consolidating network functions in State Power Corporation or its branches and subsidiary corporations, while separating generation from transmission and distribution activities. A competitive power generation market will be established based on the single buyer concept. The

    In this chapter, we will explore the dynamics of power in processes of creativity, and show its paradoxical nature as both a bridge and a barrier to creativity in organisations. Recent social psychological experimental research (Slighte, de Dreu & Nijstad, 2011) on the relation between power...... and creativity suggests that when managers give people the opportunity to gain power and explicate that there is reason to be more creative, people will show a boost in creative behaviour. Moreover, this process works best in unstable power hierarchies, which implies that power is treated as a negotiable...... and floating source for empowering people in the organisation. We will explore and discuss here the potentials, challenges and pitfalls of power in relation to creativity in the life of organisations today. The aim is to demonstrate that power struggles may be utilised as constructive sources of creativity...

    The purpose of this study is to compile what is known about larger cast components primarly in older BWR nuclear power plants with external circulation pumps. The work includes metallurgical data and a compilation on the material that the owner of Oskarshamn 1, OKG AB, has delivered to The Swedish Nuclear Power Inspectorate as a result of the investigation of these components. An overview of the investigations performed on the other Swedish plants of similar design during the annual outage 1995 is also described in this report. International experinece is also reported. The results from OKG AB show that there has been extensive cracking in both valves and pump casings and that they are probably resulting defects from the manufacturing process, but an environmental factor cannot be excluded. In order to get a complete picture of the situation in Swedish nuclear power plants a more extensive survey needs to be performed. Internationally the phenomenon of hot cracking in cast stainless steel is well known, but not as severe as in Oskarshamn 1. One question however that is discussed is the recommended amount of ferrite in these steels in order to avoid hot cracking without risking embrittlement of the ferrite phase. The Swedish utilities specify 3%, some European countries recommend 8%. Japan suggests ferrite contents up to 30%. 25 refs.

  16. Status of safety issues at licensed power plants: TMI action plan requirements, unresolved safety issues, generic safety issues

    International Nuclear Information System (INIS)

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, a program was established whereby an annual NUREG report would be published on the status of licensee implementation and NRC verification of safety issues in major NRC requirements areas. This information was compiled and reported in three NUREG volumes. Volume 1, published in March 1991, addressed the status of of Three Mile Island (TMI) Action Plan Requirements. Volume 2, published in May 1991, addressed the status of unresolved safety issues (USIs). Volume 3, published in June 1991, addressed the implementation and verification status of generic safety issues (GSIs). This annual NUREG report combines these volumes into a single report and provides updated information as of September 30, 1991. The data contained in these NUREG reports are a product of the NRC's Safety Issues Management System (SIMS) database, which is maintained by the Project Management Staff in the Office of Nuclear Reactor Regulation and by NRC regional personnel. This report is to provide a comprehensive description of the implementation and verification status of TMI Action Plan Requirements, safety issues designated as USIs, and GSIs that have been resolved and involve implementation of an action or actions by licensees. This report makes the information available to other interested parties, including the public. An additional purpose of this NUREG report is to serve as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues up until requirements are approved for imposition at licensed plants or until the NRC issues a request for action by licensees

  17. Current status and scope of gallium nitride-based vertical transistors for high-power electronics application

    International Nuclear Information System (INIS)

    Gallium nitride (GaN) is becoming the material of choice for power electronics to enable the roadmap of increasing power density by simultaneously enabling high-power conversion efficiency and reduced form factor. This is because the low switching losses of GaN enable high-frequency operation which reduces bulky passive components with negligible change in efficiency. Commercialization of GaN-on-Si materials for power electronics has led to the entry of GaN devices into the medium-power market since the performance-over-cost of even first-generation products looks very attractive compared to today's mature Si-based solutions. On the other hand, the high-power market still remains unaddressed by lateral GaN devices. The current and voltage demand for high-power conversion application makes the chip area in a lateral topology so large that it becomes difficult to manufacture. Vertical GaN devices would play a big role alongside silicon carbide (SiC) to address the high-power conversion needs. In this paper vertical GaN devices are discussed with emphasis on current aperture vertical electron transistors (CAVETs) which have shown promising performance. The fabrication-related challenges and the future possibilities enabled by the availability of good-quality, cost-competitive bulk GaN material are also evaluated for CAVETs. (invited review)

    The technical, economic, and environmental aspects of low-Btu gasification/combined-cycle power-generation (LBG/CCPG) plants are assessed, using available published data. Six base-case plants, based on three different gasifiers and two different coals, are investigated. A representative combined power cycle is selected for analysis, and material and energy balances for the six systems are developed. Emissions of various air pollutants, including sulfur dioxide and nitrogen oxides, and discharge rates of aqueous effluents are also calculated. The costs of electricity produced are derived for the six systems, using estimated plant-investment and operating costs. These costs and the emissions of various pollutants are compared with those for a conventional 500-MWe coal-based power plant using flue-gas cleaning and in compliance with the federal New Source Performance Standards. Finally, the commercialization potential of coal-based combined-cycle plants, based on the technical feasibility of building a first plant in the 1985 period and on economic viability, is evaluated. This evaluation is based on the current status of research and development programs for various components of the combined-cycle plant, such as gas turbines and fuel-gas-cleaning systems, and on the status of the demonstration plant.

    Taking as an example the Takigami geothermal power plant under construction for the scheduled operation inauguration in November 1996, this paper describes the current status and problems in environmental assessment. The current circumstances were investigated to estimate effects of the location and construction works on the surrounding environment. Then, in order to predict discharge data, a wind tunnel experiment was performed using a model of the Takigami power plant. Estimations were made on concentrations of hydrogen sulfide that falls on the ground and degrees of odor from weather data and hydrogen sulfide discharge amount. The scenery with as-built power plant was assessed visually by using computer graphics. The investigation report that compiles the result of the environmental influence investigations is used for disclosure and notification procedures for local residents and the environmental examinations by the Ministry of International Trade and Industry. The Ministry uses the investigation report and the notification report to local residents to implement examinations based on the relevant laws and regulations as well as the examination guidelines while coordinating with related local governments. Upon making final adjustments at the liaison meeting with other governmental agencies held in association with the power supply development adjustment council, the report is incorporated into the basic plan. 9 refs., 8 figs., 6 tabs.

    In rheumatology, sufficient disease control is a central part of the treatment concept. However, modern treatment strategies are associated with a substantial economic burden for health care systems. Ecological studies offer the unique opportunity to analyse differences between groups as well as group level effects. In the present analytical multi-site ecological study, we investigated whether more powerful national economies as measured by the gross domestic product per capita (GDPpc) are associated with better disease control in RA patients as measured by the disease activity score 28 (DAS28). We used aggregated data on RA patients from the recently published COMORA study as well as the World Health Organization database. There was a strong negative correlation between DAS28 and GDPpc (r = -0.815; p = 0.0002). Adjustment for sex, smoking status, disease duration or current employment status did not significantly change this association. There was a strong, negative correlation between DAS28 and age (r = -0.870; p < 0.001) and a strong, positive correlation between GDPpc and age (r = 0.737; p = 0.002). Adjustment for age reduced the regression coefficient (DAS28/GDPpc) to -0.000018 (p = 0.054). There was a negative correlation between DAS28 and current employment status (r = -0.642; p = 0.008) and a positive correlation between GDPpc and employment status (r = 0.722; p = 0.002). In conclusion, there is evidence of an association between disease control and GDPpc. This association is alleviated after adjustment for age. Of note, in countries with higher GDPpc, a higher proportion of RA patients are currently employed. This is true despite the fact that RA patients in countries with higher GDPpc are also older.

    The development is described of the large-area SPN-detector as an out of core power monitoring system. Gadolinium or cobalt was used as the emitter. Response functions of the gadolinium SPN-detector were found with regard to the reactor power, the effect of the gamma field, its short-term behaviour following reactor shutdown and long-term behaviour during reactor operation. It was shown that a detector of 0.1 mm emitter thickness can withstand an integral thermal neutron flux of 2.1020 nvt almost without efficiency loss thus indicating that the large-area gadolinium SPN-detector is a suitable means for power monitoring in large HTGR's

    Full Text Available The renewable energy emerged as a solution to the environmental problems caused by the conventional sources of energy. Small hydropower (SHP is claimed to cause negligible effects on the ecosystem, although some environmental values are threatened and maintenance of an adequate water quality should be ensured. This work provides a characterization of the water quality status in a river stretch around a SHP plant on river Lérez, northwest Spain, for four years after its construction. The ecological and chemical status of the water as well as the ecological quality of the riparian habitat, were used as measures of quality. Data were compared with the water quality requirements. The variations in the quality parameters were analyzed over time and over the river sections with respect to the SHP plant elements. Two years after construction, the temperature and dissolved oxygen values achieved conditions for salmonid water and close to the reference condition, while pH values were low. The Iberian Biological Monitoring Working Party (IBMWP index showed a positive trend from two years after the construction and stabilized at “unpolluted or not considerably altered water”. Quality parameters did not present significant differences between sampling points. The SHP plant construction momentarily altered the quality characteristics of the water.

    Japan situation has not significantly changed since 2012, almost all its nuclear power plants are still stopped. The process for restarting 48 of them is under way but expected to take some years. As last year no order was registered, but 2013 met an important number of building starts concerning 10 new PWR (11.3 GWe): 1 - Belarus: First building site in eastern Europe (excluded Russia) for more than 25 years. 2 - USA: Four PWR units (4.5 GWe) that represent the first new buildings in this country since 1977. 3 - China: Three new PWR, that leads to a total of 27 plants under construction in this country. 4 - United Arab Emirates and South Korea: The sister-ships of Barakah-2 and Shin-Hanul-2 started right after the No.1 units in 2012. These 10 new plants are all PWR units, which is coherent with the worldwide situation of 58 PWR constructions for only 4 PHWR in India (and 4 BWR - 2 in Japan and 2 in Taiwan - all delayed for different reasons). Worldwide capacity balance Despite the commercial start of 3 GWe (2 PWR in China, 1 in Iran), the planned shutdown of 6 units (5.4 GWe: Fukushima-Daishi 5 and 6 in Japan and 4 PWR in USA) leads to a decrease of -2.4 GWe of the nuclear capacity. Thanks to a better average load factor the overall nuclear electricity production still increases of 13 TWh. But as 4.1 GWe (3 PWR in China, 1 in India) were connected to the grid and the constructions represent more than 50 units with about 10 annual commercial operations for the next four years, this loss of capacity should be exceptional.

    2016-01-01

    Shandong is considered to be the top provincial emitter of air pollutants in China due to its large consumption of coal in the power sector and its dense distribution of coal-fired plants. To explore the atmospheric emissions of the coal-fired power sector in Shandong, an updated emission inventory of coal-fired power plants for the year 2012 in Shandong was developed. The inventory is based on the following parameters: coal quality, unit capacity and unit starting year, plant location, boiler type and control technologies. The total SO2, NOx, fine particulate matter (PM2.5) and mercury (Hg) emissions are estimated at 705.93 kt, 754.30 kt, 63.99 kt and 10.19 kt, respectively. Larger units have cleaner emissions than smaller ones. The coal-fired units (≥300 MW) are estimated to account for 35.87% of SO2, 43.24% of NOx, 47.74% of PM2.5 and 49.83% of Hg emissions, which is attributed primarily to the improved penetration of desulfurization, LNBs, denitration and dust-removing devices in larger units. The major regional contributors are southwestern cities, such as Jining, Liaocheng, Zibo and Linyi, and eastern cities, such as Yantai and Qindao. Under the high-efficiency control technology (HECT) scenario analysis, emission reductions of approximately 58.61% SO2, 80.63% NOx, 34.20% PM2.5 and 50.08% Hg could be achieved by 2030 compared with a 2012 baseline. This inventory demonstrates why it is important for policymakers and researchers to assess control measure effectiveness and to supply necessary input for regional policymaking and the management of the coal-fired power sector in Shandong.

    Concentration of selenium in whole blood and plasma, lipid peroxides in plasma, and glutathione peroxidase activities in red blood cell hemolysates and plasma were determined in 49 coal power plant workers and in 50 rubber factory workers. The results were compared with those obtained for 58 nonindustrial controls. Whole blood selenium was significantly lower and plasma lipid peroxides were significantly higher in power plant workers when compared to the nonindustrial group. In the rubber factory workers, whole blood selenium and red blood cells and plasma glutathione peroxidase activities were significantly lower than in the control group. Urinary output of selenium was also significantly decreased in rubber factory workers. Slightly elevated lipid peroxides were also observed in that group. It seems reasonable to conclude that the lower blood selenium and decreased urinary output of this element may result from increased loss of selenium with perspiration. No correlation has been observed between selenium concentration and glutathione peroxidase activity and between enzyme activity and lipid peroxides concentration in the industrial group.

    Free-piston Stirling power conversion has been identified as a viable option for potential Fission Surface Power (FSP) systems on the Moon and Mars. Proposed systems consist of two or more Stirling convertors, in a dual-opposed configuration, coupled to a low-temperature uranium-dioxide-fueled, liquid-metal-cooled reactor. To reduce developmental risks associated with liquid-metal loop integration, a test rig has been built to evaluate the performance of a pair of 1-kW free-piston Stirling convertors using a pumped sodium-potassium (NaK) loop for thermal energy input. Baseline performance maps have been generated at the Glenn Research Center (GRC) for these 1-kW convertors operating with an electric heat source. Each convertor was then retrofitted with a custom-made NaK heater head and integrated into a pumped NaK system at the Marshall Space Flight Center (MSFC). This paper documents baseline testing at GRC as well as the progress made in integrating the Stirling convertors into the pumped NaK loop.

  15. Status of high power solid state laser for laser fusion experiments and the prospect of future reactor drivers

    International Nuclear Information System (INIS)

    The progress in development of high-power glass laser systems during the past 30 years is remarkable. NIF (National Ignition Facility), which will deliver 1.8 MJ at 0.35 μm is now under construction in the United States. Recently, technology that smoothes out the focal pattern has been developed to a great extent. RPP (Random Phase Plate) and PCL (Partially Coherent Laser) both gave an excellent focal pattern with standard deviation of 3% in the Gekko XII laser system. In the US, Japan, and Europe, several ultra-short pulse lasers were developed for research on 'fast ignition'. 'Fast ignition' is a method which will reduce the total required laser energy for ignition. Because a diode-pumped solid state laser can operate at a repetition rate of over 10 Hz with an efficiency of about 10%, research area of high-power systems at the 1 kW level started to focus on the development of a driver for a commercial laser fusion reactor.

  16. Development status of metallic, dispersion and non-oxide advanced and alternative fuels for power and research reactors

    International Nuclear Information System (INIS)

    The current thermal power reactors use less than 1% of the energy contained in uranium. Long term perspectives aiming at a better economical extraction of the potential supplied by uranium motivated the development of new reactor types and, of course, new fuel concepts. Most of them dated from the sixties including liquid metal cooled fast (FR) and high temperature gas cooled (HTGR) reactors. Unfortunately, these impulses slowed down during the last twenty years; nuclear energy had to face political and consensus problems, in particular in the United States of America and in Europe, resulting from the consequences of the TMI and Chernobyl accidents. Good economical results obtained by the thermal power reactors also contributed to this process. During the last twenty years mainly France, India, Japan and the Russian Federation have maintained a relatively high level of technological development with appropriate financial items, in particular, in fuel research for the above mentioned reactor types. China and South Africa are now progressing in development of FR/HTGR and HTGR technologies, respectively. The purpose of this report is not only to summarise knowledge accumulated in the fuel research since the beginning of the sixties. This subject has been well covered in literature up to the end of the eighties. This report rather concentrates on the 'advanced fuels 'for the current different types of reactors including metallic, carbide and nitride fuels for fast reactors, so-called 'cold' fuels and fuels to burn excessive ex-weapons plutonium in thermal power reactors, alternative fuels for small size and research reactors. Emphasis has been put on the aspects of fabrication and irradiation behaviour of these fuels; available basic data concerning essential properties that help to understand the phenomena have been mentioned as well. This report brings complementary information to the earlier published monographs and concerns developments carried out after the early

    The steam generators in Hanbit Unit 3 and 4 are scheduled to be replaced in 2018 and 2019, respectively. Nevertheless, the wastes from the dismantled steam generators are currently just on-site stored in the NPP because there are no disposal measures for the waste and lack of the decontamination techniques for large-sized metallic equipment. In contrast, in the oversea NPPs, there are many practical cases of chemical decontamination not only for oversized components in the NPPs such as reactor pressure vessel and steam generator, but also for major pipes. Chemical decontamination technique is more effective in decontaminating the components with complicated shape compared with mechanical one. Moreover, a high decontamination factor can be obtained by using strong solvent, and thereby most of radionuclides can be removed. Due to these advantages, the chemical decontamination has been used most frequently for operation of decontaminating the large-sized equipment. In this study, an analysis on the current status of chemical decontamination technique used for the steam generators of the foreign commercial NPPs was performed. In this study, the three major chemical decontamination processes were reviewed, which are applied to the decommissioning process of the steam generators in the commercial NPPs of the United States, Germany, and Belgium. The three processes have the different features in aspect of solvent, while those are based in common on the oxidation and reduction between the target metal surface and solvents. In addition, they have the same goals for improving the decontamination efficiency and decreasing the amount of the secondary waste generation. Based on the analysis results on component sub-processes and major advantages and disadvantages of each process, Table 2 shows the key fundamental technologies for decontamination of the steam generator in Korea and the major considerations in the development process of each technology. It is necessary to prepare

  19. Comprehensive evaluation of new probabilistic safety analyses (PSA) for nuclear power stations outside Germany and status report on safety engineering

    International Nuclear Information System (INIS)

    This report was prepared on behalf of the Minister of Environment, Nature Conservation and Nuclear Safety. It summarizes the results of an analysis of the state of the art of foreign Probabilistic Safety Assessments (PSA) for nuclear power plants. Main features of selected PSA documents, characterizing methods and their application within the framework of operational safety assessment, are presented as well as insights gained from discussions with utilities and an authority. German examples of PSA were compared to the foreign analyses using experiences of the TUeV Nord e.V. from reviewing PSA. This comparison covers PSA of level 1. It was found that German PSA methods are generally comparable to the foreign approaches. Nevertheless differences were found with respect to the scope of operational states covered by the analyses, the details down to which human error analyses were performed as well as some special issues. The foreign examples demonstrate an extended application of PSA within the operational safety management. Experiences that were gained within this process over years form an appropriate basis for the establishment of probabilistic safety criteria as well as procedures for incorporating PSA into the operational safety evaluation process. A procedure is proposed for further performing and evaluating PSA and their results in Germany. (orig.)

  20. Mechanistic understanding of irradiation-induced corrosion of zirconium alloys in nuclear power plants: Stimuli, status, and outlook

    International Nuclear Information System (INIS)

    Failures in the basic materials used in nuclear power plants continue to be costly and insidious, despite increasing industry vigilance to catch failures before they degrade safety. For instance, the overall costs to the US industry from materials problems could amount to as much as $10 billion annually. Moreover, estimates indicate that the cost of a pipe failure in a nuclear plant is one hundred times greater than the cost of a similar failure in a coal-fired plant. There are important practical stimuli and much scope for further understanding of the effects of irradiation on Zr-alloys (and other materials used in nuclear installations) by careful experimentation. Moreover, these studies need to address the effect of irradiation on all components of heterogeneous systems: the metal, the oxide and the environment, and especially those processes recurring at the interphases between these components. The present paper is aimed at providing specialists with some systematic information on the subject and with important considerations on the key items for further experimentation

    The Nováky Power Station (NPS) has been using since 1953 as fuel coal with a high content of As and with a low content of other metals. This involves a constant risk for the workers as well as pollution of the surroundings. The authors described 16 cases of chronic As intoxication in NPS workers after 22.3 +/- 8.4 years of exposure (especially stokers, maintenance workers, boiler cleaners). Among clinical symptoms prevailed sensory and motor polyneuropathy (13 cases), pseudoneurasthenic syndrome (10 cases), toxic encephalopathy (6 cases) and nasal septum perforation (2 cases). After 1989 the intoxications with As did not occur any more due to technical measures and health protection of the workers. The authors present a review of actual results of clinical, haematological and biochemical investigations and tests for metals (AAS methods) in biological materials of workers at risk in NPS (n = 70), exposed on average for 11.9 +/- 0.5 years, of average age 35.91 +/- 1.7 years (mean +/- SE) and compared the results to a matched control group of blood donors not exposed to metals (n = 29). In NPS workers significantly lower Hb values, higher serum creatinine, higher serum beta 2-microglobulin, higher As content in hair as well as higher serum Mn and Pb concentrations compared with the C-group were found. The exposed group had significantly lower serum Se concentrations (0.64 +/- 0.025 mumol/l (mean +/- SE) compared to Se levels of persons from an adjacent district. The authors stress the necessity of individual evaluation of the metal concentrations in relation to clinical findings. With prolonged exposure the situation can become more urgent not only because of chronic poisoning but also because of the cancerogenic effects of these elements on the human organism. PMID:9524739

    International Nuclear Information System (INIS)

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, the NRC established a program for publishing an annual report on the status of licensee implementation and NRC verification of safety issues in major NRC requirements areas. This information was initially compiled and reported in three NUREG-series volumes. Volume 1, published in March 1991, addressed the status of Three Mile Island (TMI) Action Plan Requirements. Volume 2, published in May 1991, addressed the status of unresolved safety issues (USIs). Volume 3, published in June 1991, addressed the implementation and verification status of generic safety issues (GSIs). The first annual supplement, which combined these volumes into a single report and presented updated information as of September 30, 1991, was published in December 1991. The second annual supplement, which provided updated information as of September 30, 1992, was published in December 1992. Supplement 2 also provided the status of licensee implementation and NRC verification of other multiplant action (MPA) issues not related to TMI Action Plan requirements, USIs, or GSIs. Supplement 3 gives status as of September 30, 1993. This annual report, Supplement 4, presents updated information as of September 30, 1994.

    International Nuclear Information System (INIS)

    The situation in Japan has not evolved significantly since 2012: all its nuclear power plants are idle and safety improvements are being carried out. Several plants, however, are going through the regulatory process required to restart - the first to be implemented are expected in 2015. Few projects have been reported to be in the building phase (programs in the United Arab Emirates and in Belarus proceed), but the CAREM25 project is significant as it is the first SMR (Small Modular Reactor) to be built in the world. There is still a considerable number of ongoing building programs - i.e. more than 60 units. The commercial start of 7 reactors in China and 1 reactor in India - all of which are PWR -, offsets the decrease in installed capacity which began in 2011. This capacity increase (up 6.3 GWe) leads to an increase in nuclear electricity production (up 60 TWh). Considering the ongoing programs this trend should persist, as more than 5 commercial starts are expected each year for the next 3 years.

The study results on the economic benefits of the wind power integration in China's present stage indicate that the wind power industry is in good profit condition. The profit levels are higher in areas with the richer wind resources. Expanding the margin of the power purchase prices in different resource areas is beneficial to the nationwide proportionate development of wind power. At last, the present and future benefits for the energy conservation and emission reduction from the wind power integration were estimated. The forecast result indicates that the environmental benefits of "wind-thermal exchange" will be increased along with the expansion of the using scale of wind power.

    People are working around the clock communicating with one another on the electronic platform even after work. We examined the outcomes of Working through Information and Communication Technologies after Hours (W_ICTs), and attempted to delineate the mechanism of W_ICTs. Findings of previous researches on W_ICTs’ were inconsistent in terms of their impacts on people’s work and life, with some being positive while others being negative. This obscured people’s general perceptions of the possible effects of W_ICTs’, thus challenging our recommendation on the management of W_ICTs. Furthermore, previous studies on the mechanism of W_ICTs focused more on the impact on the individuals or the organizations, without considering the effect on individuals’ spouses. Most previous studies were also limited in the sense that they had been conducted in the western cultural context, with a lack of localized research in the Chinese culture. The present study based on the Spillover-Crossover Effect among dual-earner Chinese couples, therefore, is intended to fill the gap by investigating the positive and negative effects of W_ICTs on the well-being of both husbands and wives in China. The study surveyed 278 Chinese dual-earner couples who had fixed working hours. They completed the W_ICTs scale, the work-to-family conflict scale, the work-to-family facilitation scale, the social undermining scale, the work satisfaction scale and the marital satisfaction scale. In the study, ‘whether the couples have children under the age of 18’ and ‘whether the couples’ parents help with the children’s housework’ were treated as control variables. The structural equation model, the dyadic data analysis method, and the bias corrected bootstrap method were used to examine the research hypotheses. The results showed that: (1) W_ICTs was positively related to work-to-family conflict and work-to-family facilitation; (2) work-to-family conflict was positively related to spouses

    员工建言对于组织运营和发展的作用是不言而喻的,然而在中国情境下往往事与愿违,员工常常会选择知而不言.采用问卷调查方式收集81名团队领导与其467名下属的配对样本,运用多层线性模型方法,从文化价值观的视角探讨中国情境下不同层级个体的权力距离导向对员工建言的效应以及领导组织地位感知和员工组织地位感知在其中的调节效应.统计分析结果表明,领导权力距离导向和员工权力距离导向对员工建言行为都具有显著的负向预测作用,领导组织地位感知显著调节领导权力距离导向与员工建言间的关系,员工组织地位感知显著调节员工权力距离导向与员工建言间的关系.研究结果有助于理解中国情境下员工建言的影响因素和边界条件,对于改变这种现状、实现组织的有效管理具有重要的现实意义.%Employee voice plays an important role in organization operation and development. However, employees in Chinese context usually avoid voice. In a survey-based study of 467 employees nested within 81 workgroups, using hierarchical linear model, this study examined the cross-level effects of power distance orientation on employee voice and the moderating effect of perceived organizational status of leader and employee in China context based on culture value theories. We found that leader and employee power distance orientation both have significantly negative effects on employee voice, and leader perceived organizational status and employee perceived organizational status respectively moderate the relationships between power distance orientation and employee voice in different levels. Results are useful to understand the antecedents and boundary condition of employee voice, which is meaningful to change employee voice behaviors and improve managerial effectiveness.

    This report evaluates the state of the art and effectiveness of physical coal cleaning as a potential strategy for controlling SO/sub x/ emissions in coal fired power generation. Coal properties which are significantly altered by physical coal cleaning were determined. The effects of the changes in properties as they relate to pulverized coal firing, fluidized bed combustion and low Btu gasification for combined cycle powered generation were studied. Available coal washability data were integrated by computer with U.S. coal reserve data. Approximately 18% of the demonstrated coal reserve were matched with washability data. Integrated data appear in the Appendix. Current coal preparation practices were reviewed. Future trends were determined. Five process flow sheets representing increasing levels of cleaning sophistication were prepared. The clean product from each flow sheet will meet U.S. EPA New Source Performance Standards. Capital and operating costs for each case were estimated. Environmental control technology and environmental impact associated with current coal preparation and cleaning operations were assessed. Physical coal cleaning is widely practiced today. Where applicable it represents the least expensive method of coal sulfur reduction. Developmental physical and chemical coal cleaning processes were studied. The chemical methods have the advantage of being able to remove both pyritic sulfur and organic sulfur present in the coal matrix. Further R and D efforts will be required before commercialization of these processes.

    International Nuclear Information System (INIS)

    The main emphasis of this presentation and paper is to address why experts believe that today's operating nuclear power reactors are much safer than they were 10 or 20 years ago. There is strong evidence to support this belief for the power reactors now operating in all of the advanced countries, and in many of the less developed countries too, although in a few of these latter countries there are continuing safety concerns. The paper will present recent and historical data from the U.S., a discussion of what the data mean and why, and a perspective about what events and trends have been the causes for the major safety improvements that have occurred. The extension of the conclusion to other countries will also be discussed. Finally, the reasons why safety-improvement programs must continue in some of the less-developed countries are described

    An investigation of whether body water changes during the Giro d'Italia affected average maximal mean power (MMP) of different time durations and to establish whether phase-angle and body cell mass (BCM) are related to MMP in elite cyclists. Approximately 2 h after each stage of the race, a bioelectrical impedance analysis was performed on 8 cyclists and analysed according to bioelectrical impedance vector analyses. Additionally, MMP of different time durations were recorded during each stage. Body mass increased (p<0.001), vector-length shortened (p<0.001) and MMP15 (maximal mean power for 15 s; p=0.043) decreased in the course of the Giro d'Italia. The shortening of the vector was negatively related to MMP10 (r=- 0.749, p=0.032) and MMP15 (r=- 0.735, p=0.038) during stage 16 (heavy mountain-stage) and MMP60 (r=- 0.751, p=0.032), MMP300 (r=- 0.739, p=0.036) and MMP1800 (r=- 0.769, p=0.026) during stage 19 (time-trial). Additionally, the baseline phase-angle and BCM were associated to MMP15 best (r=0.781, p=0.022 and 0.756, p=0.030, respectively). In the course of the Giro d'Italia, MMP15 decreased, indicating progressive fatigue. The vector-length shortening and to some extent the body mass increase indicate that cyclists gained body water during the race. This gain was positively associated with performance during the last stages, possibly due to improved thermoregulation. Furthermore, phase-angle and BCM, shown to be linked to cellular function and to represent metabolic active tissue, reflect individual MMP of short duration in professional road cyclists.

  16. 18F-FDG PET/CT following chemoradiation of uterine cervix cancer provides powerful prognostic stratification independent of HPV status: a prospective cohort of 105 women with mature survival data

    International Nuclear Information System (INIS)

    To report 5-year outcomes of a prospective registry study investigating posttherapy FDG PET/CT in women with locally advanced cervical cancer. A secondary analysis assessing the prognostic significance of HPV infection was performed. Patients underwent definitive chemoradiation followed by a single FDG PET/CT scan for response assessment. A complete metabolic response (CMR) was defined as no evidence of FDG-avid disease. Patients were dichotomized according to HPV infection status into a 'higher-risk' group and a 'lower-risk' group, with the higher-risk group comprising those with alpha-7 strain HPV (subtypes 18, 39 and 45) and those who were HPV-negative and the lower-risk group comprising those with alpha-9 strain HPV (subtypes 16, 31, 33, 52 and 58) and those with mixed strains. Survival outcomes, patterns of failure and salvage therapy outcomes were investigated for their association with metabolic response and HPV status. In 105 patients the median prospective follow-up was 5.2 years. The 5-year cancer-specific, overall and progression-free survival rates in patients with a CMR were 97 %, 93 % and 86 %, respectively. In patients without a CMR, the corresponding 5-year survival rates were 36 %, 22 % and 0 % respectively (p < 0.01). PET response was associated with patterns of failure (p < 0.01), with the 5-year freedom from local, nodal and distant failure in patients with a CMR being 94 %, 90 % and 94 %, respectively. Of 16 patients who underwent salvage therapy, 12 had disease detected on the surveillance PET scan, and 8 achieved a post-salvage CMR of whom all were alive at a median of 4.9 years. DNA adequate for HPV analysis was extracted in 68 patients. The likelihood of a PET metabolic response was not influenced by HPV infection status, with 71 % and 75 % of higher-risk and lower-risk patients, respectively, achieving CMR (p = 0.83). Higher-risk patients had a poorer OS (HR 2.6, range 1.0 - 6.6, p = 0.05) in univariable analysis but

    It is a very important and fundamental work to monitor soil water status in real time for irrigation management in modern irrigation district. This paper presented a system with low cost and low power dissipation to monitor soil water status for areal irrigation management. The instrument of soil water monitoring contains a microcontroller-based system and is powered by 1# dry cell. All of the measurement data would be sent to web server through GPRS (general packet radio services) chipset assembled in it, for analysis and use in irrigation management based on each point of distributed framework. There were 4 sets of soil water content and temperature sensors and 1 set of water potential sensor designed, which could be installed at different depth in the crop root zone to meet the demand of irrigation management. However, it could be configured with less or more sensors in the system according to the channel values of the data acquisition unit, if there was a demand in the field investigation. This process had an advantage to assess the soil moisture more accurately. The microcontroller-based system and designed circuit had the responsibility to collect/log/transfer/control the data of soil water content, temperature and water potential once every 1 h. It was a very low-power dissipation system because the center processor supported energy to each unit when it needed. The interval of data collecting could be scheduled from 30 min to 24 h if necessary. All of the daily data would be transferred to the web server and the user's E-mailbox to check out or analyze. Users could receive the alarm information if the monitoring system had errors or was out of gear. They could configure the data logger near the monitoring system in wireless network, or through the internet server using GPRS technology. The designed system was installed in the whole crop growth season in 2014 in Jiefangzha Irrigation Area, Hetao Irrigation District, Inner Mongolia. The 10 sets of real

    The co-combustion of wastes in power stations is an additional option for the thermal treatment of certain waste materials and thus for complying with the specifications of the German TA-Siedlungsabfall (technical directive on disposal of municipal solid waste). The present investigation compiles the status of knowledge about co-combustion of sewage sludge, biomass and selected waste materials in coal-fired power stations. The results are meant to provide extensive assistance to evaluate the processes and thus to contribute to sort out uncertainties, both on the part of power plant operators and of the authorities. Based on the information acquired, the report shall point out the gaps in knowledge, the further need for research and development and the need for action conerning the authorities. By enquiries at disposal enterprises, power station operators as well as authorities, the literature work was completed and a comprehensive view of the current situation in Germany elaborated. The report points out the legal conditions of co-combustion and supplementary fuel potentials, presents the process engineering of co-combustion, and examines the obstacles encountered during the technical conversion, the environmental questions, and the potential for co-combustion of the above materials in existing power stations. The electrical power sector is subject to strong changes due to the liberalisation of the energy market. The pressure on costs has increased and the periods available for planning are shorter. On the one hand, this arouses an increased interest in co-combustion of waste materials because of possible additional payments for the wastes. On the other hand, however, initiatives in this respect are counteracted by high investments costs necessary for the introduction of co-combustion with the existing high environmental standards. What is more, the competitive situation reduces the exchange of experience between the power station operators. Co-combustion of sewage

    Rising expectations best characterize the current prospects of nuclear power in a world that is confronted with a burgeoning demand for energy, higher energy prices, energy supply security concerns and growing environmental pressures. It appears that the inherent economic and environmental benefits of the technology and its excellent performance record over the last twenty years are beginning to tilt the balance of political opinion and public acceptance in favour of nuclear power. Nuclear power is a cost-effective supply-side technology for mitigating climate change and can make a substantial contribution to climate protection. This paper reviews the current status of nuclear power and its fuel cycle and provides an outlook on where nuclear power may be headed in the short-to-medium run (20 to 40 years from now). (auth)

  9. Estimated status 2006-2015

    International Nuclear Information System (INIS)

    According to article 6 of the French law from February 10, 2000 relative to the modernization and development of the electric public utility, the manager of the public power transportation grid (RTE) has to produce, at least every two years and under the control of the French government, a pluri-annual estimated status. Then, the energy ministry uses this status to prepare the pluri-annual planning of power production investments. The estimated status aims at establishing a medium- and long-term diagnosis of the balance between power supply and demand and at evaluating the new production capacity needs to ensure a durable security of power supplies. The hypotheses relative to the power consumption and to the evolution of the power production means and trades are presented in chapters 2 to 4. Chapter 5 details the methodology and modeling principles retained for the supply-demand balance simulations. Chapter 6 presents the probabilistic simulation results at the 2006, 2010 and 2015 prospects and indicates the volumes of reinforcement of the production parks which would warrant an acceptable level of security. Chapter 7 develops the critical problem of winter demand peaks and evokes the possibilities linked with demand reduction, market resources and use of the existing park. Finally, chapter 8 makes a synthesis of the technical conclusions and recalls the determining hypotheses that have been retained. The particular situations of western France, of the Mediterranean and Paris region, and of Corsica and overseas territories are examined in chapter 9. The simulation results for all consumption-production scenarios and the wind-power production data are presented in appendixes. (J.S.)

    A home care Hospice programme was set up to provide care to the patients with advanced diseases and their families in Singapore. After office-hour, the service is managed by a doctor on weekdays, with the assistance of a nurse during daytime on Saturdays, Sundays and public holidays. The doctor on-call made an average of 3.1 phone calls and 1.3 visits each weekday evening. Over the weekends and public holidays, there were a mean of 16.7 phone calls and 6 visits each day. More than half of the visits (50.3%) were made for certification of death. The commonest symptoms that prompted visits were dyspnoea (20%) and pain (12.2%). The busiest period during weekdays was between 6.00 pm and 11.00 pm, when our doctors did most of their visits. The workload of the hospice home care service is likely to increase and resources such as family health physicians can be explored to help to meet this increasing demand. This can be achieved through the provision of comprehensive training and easy accessibility to medical records which are kept with patients. PMID:14569717

    The results of the determination of radionuclide and chemical (multielement analysis) soil pollution are presented. The data on antioxidant status of plantain (Plantago major L.) in conjunction with the data on radionuclide and chemical pollution are analyzed. The most significant decrease in antioxidant activity of plant seeds was observed in areas situated along the most frequent wind direction in the region in summer 1998. It is suggested that lower antioxidant status is caused by the chronic radionuclide release on the chemically polluted territories.

    Full Text Available With few prospects for the resolution of the Cyprus dispute, the costs of the status quo are rising for Turkey. This article argues that Turkey could regain initiative without sacrificing its national interests by withdrawing its military forces stationed on the island and organizing a referendum on the future of the TRNC. The removal of the military would terminate Turkey's status as an occupying power, while a referendum could add legitimacy to the TRNC and put pressure on Cyprus.

    Nomura, Shuhei; Blangiardo, Marta; Hodgson, Susan

    2016-01-01

    Objective Radiation fears following Japan's 2011 Fukushima nuclear disaster affected levels of physical activity in local children. We assessed the postdisaster versus predisaster weight status in school children and evaluated to what extent school restrictions on outdoor activities that were intended to reduce radiation exposure risk affected child weight. Participants We considered children aged 13–15 years from 4 of the 5 secondary schools in Soma City (n=1030, 99.1% of all children in the city), located in 35–50 km from the Fukushima nuclear plant, postdisaster (2012 and 2015) and predisaster (2010). Methods Weight status, in terms of body mass index (BMI), percentage of overweight (POW) and incidence of obesity and underweight (defined as a POW ≥20% and ≤−20%, respectively) were examined and compared predisaster and postdisaster using regression models. We also constructed models to assess the impact of school restrictions on outdoor activity on weight status. Results After adjustment for covariates, a slight decrease in mean BMI and POW was detected in females in 2012 (−0.37, 95% CI −0.68 to −0.06; and −1.97, 95% CI −3.57 to −0.36, respectively). For male children, obesity incidence increased in 2012 (OR for obesity: 1.45, 95% CI 1.02 to 2.08). Compared with predisaster weight status, no significant weight change was identified in 2015 in either males or females. School restrictions on outdoor activities were not significantly associated with weight status. Conclusions 4 years following the disaster, weight status has recovered to the predisaster levels for males and females; however, a slight decrease in weight in females and a slight increase in risk of obesity were observed in males 1 year following the disaster. Our findings could be used to guide actions taken during the early phase of a radiological disaster to manage the postdisaster health risks in adolescent children. PMID:27683520

    The KamLAND experiment can explore world lowest mass difference region of neutrino oscillation parameter with an artificial neutrino source. It observes anti-neutrinos from various power plants spread in Japan with about 175 km baseline. This baseline is two order of magnitude longer than those of previously performed reactor experiments 1,2. This challenging measurement requires very low background environment as low as 10-13 g/g Uranium and Thorium impurities. In order to achieve this very low impurity level, various techniques (detector design, material selection, construction scheme etc) have been invested. These efforts have been rewarded rather quickly and current achievement doesn't hinder even the 7Be solar neutrino observation requiring 10-16 g/g U and Th impurities. Various background sources relevant to the reactor and solar neutrino observation are considered and description of efforts to eliminate those backgrounds are the main issue of this manuscript. Physics goal and current successful construction status are also highlighted.

    The TESLA Test Facility (TTF), under construction at DESY by an international collaboration, is an R and D test bed for the superconducting option for future linear e+/e-colliders. It consists of an infrastructure to process and test the cavities and of a 500 MeV linac. The infrastructure has been installed and is fully operational. It includes a complex of clean rooms, an ultra-clean water plant, a chemical etching installation and an ultra-high vacuum furnace. The linac will consist of four cryo-modules, each containing eight 1 meter long nine-cell cavities operated at 1.3 GHz. The base accelerating field is 15 MV/m. A first injector will deliver a low charge per bunch beam, with the full average current (8 mA in pulses of 800 {mu}s). A more powerful injector based on RF gun technology will ultimately deliver a beam with high charge and low emittance to allow measurements necessary to qualify the TESLA option and to demonstrate the possibility of operating a free electron laser based on the Self-Amplified-Spontaneous-Emission principle. Overview and status of the facility will be given. Plans for the future use of the linac are presented. (R.P.). 19 refs.

  11. Status of NESTOR

    International Nuclear Information System (INIS)

    NSC KIPT proposed to construct a new X-ray and soft ultraviolet source NESTOR with a 40 - 225 MeV electron storage ring in Kharkov. NESTOR is a new type radiation source on the base of Compton scattering and a storage ring. Electrons are injected in the storage ring at 100 MeV and ramped up to final energy of 225 MeV. So, using interaction angle 10 deg. and 150 deg., the facility covers operation energy range of radiation from soft ultraviolet trough synchrotron radiation from bending magnets up to hard X-ray radiation through Compton scattering (∼1 eV ∼1 MeV). It is supposed that stored electron beam current will be of about 200 mA. Along with use of Nd:Yag laser of 10 W average power which was developed by High-Q laser firm and optical resonator with accumulation gain of about 1000 it allows to provide X-ray radiation flux up to 1011 phot/s. NESTOR is the cooperative facility and its development is supported by Ukrainian government and NATO SfP project number 977982. It is supposed that NESTOR will be in operation by mid-2007 year. The status of the project and main facility systems are described in the report

  19. renewables 2011 - Global status report

    International Nuclear Information System (INIS)

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2011. The report covers both current status and key trends; by design, it does not provide analysis or forecast the future. Global energy consumption rebounded in 2010 after an overall downturn in 2009. Renewable energy, which experienced no downturn in 2009, continued to grow strongly in all end-use sectors - power, heat and transport - and supplied an estimated 16% of global final energy consumption. Renewable energy accounted for approximately half of the estimated 194 gigawatts (GW) of new electric capacity added globally during the year. Renewables delivered close to 20% of global electricity supply in 2010, and by early 2011 they comprised one quarter of global power capacity from all sources. In several countries, renewables represent a rapidly growing share of total energy supply, including heat and transport

    operation because of contract problems and a number of projects in Holland, Italy and Brazil never got to a construction phase. Indirect co-firing has been realised in a few plants where a CFB gasifier is combined with some cooling and cyclone particle removal. If gas cleaning before firing can be achieved, the technology is believed to have a bigger potential. That would mean that waste fuel or other fuels with high chlorine content can be used, and also that the treated gas can be used in an incineration plant without limiting the superheater temperature to the low levels, in relation to power plant boilers, that is used in waste boilers. This means that both the efficiency to electricity and the ratio between electricity and heat production can be increased, in relation to waste incineration. Improvements in performance during the time period in question require that initiatives are taken and that e.g. gas turbine manufacturers participate actively. The probability for this development is more difficult to assess. For BIG-ICE, the technology is assessed to reach 35-40 % electricity efficiency at the end of the period, i.e. 2025-2030, and the investment cost for bigger plants can be just below that of comparable conventional steam plants, perhaps 3 000 Euro/kWe for a complete plant.

    In electric power systems, overcome the stage of the remote system (SCADA) implementation, the current tendency is the automation and use of open architectures. That tendency is reflected in the use of standardized local area networks of industrial use and adoption of data transmission protocols which are based in international standards. The result is the connectivity and operationalization among the local devices and terminals usually called IED. In this document it is presented a summary of the standardized data transmission protocols, which have been used in electric power substations currently, based on a architecture which defines three layers of the OSI/ISO reference pattern. Based on the tendency increase of automation in substations, some ways of communication have been analyzed, they mean: local area networks such as the Ethernet pattern and some industrial ones and others such as Profibus and its respective implementation in electric power systems. It also is analyzed the tasks which have supported IEC and EPRI for defining a standardization and a model for the open communications in electric power substations.

  5. Analysis on The Status of National Industries Following The 1997 Multi Dimensional Crisis in Relation to the Planning of National Participation Program in the Construction of Nuclear Power Plant

    International Nuclear Information System (INIS)

    Various issues (fundamental problems) related to the recant status of national manufacturing industries following the 1997 multi-dimensional crisis have been identified, analyzed, and the recommended solution has been proposed. The most recent status of national industries is deemed important to be considered in the planning of national participation for the incoming NPP Project. Information on the condition of national industries is acquired from literatures, media, seminar, as well as from discussion during technical visitation to relevant institutions and companies. The identified issues are classified into 5 aspects, i.e. structural, operational, technical, financial, and cultural. To each aspect, solution concept have been promoted by involving the stake holder in order to achieve the highest level of synergy. Cultural aspects is perceived to be the most fundamental aspect inducing the other aspects. Therefore, for the certainty of direction of industrial development, it deemed necessary to introduce the appropriate Values System for controlling the behavior of the stake holder. An alternative Value System has been recommended, i.e. good corporate governance and total quality management. Furthermore, it is identified that following the 1997 crisis, during 1998 the output national industries decreased -11.4% , but during 1999-2003 has been steadily increasing by 3.9%, 6.0%, 3.1%. This shows that globally, after 2003 national industries can be perceived to be well recovered from the crisis. Consequently, all the previous results of study on national participation can still be used as reference in planning national participation program, provided that an ever-ending updating study still need to be done.

    operation because of contract problems and a number of projects in Holland, Italy and Brazil never got to a construction phase. Indirect co-firing has been realised in a few plants where a CFB gasifier is combined with some cooling and cyclone particle removal. If gas cleaning before firing can be achieved, the technology is believed to have a bigger potential. That would mean that waste fuel or other fuels with high chlorine content can be used, and also that the treated gas can be used in an incineration plant without limiting the superheater temperature to the low levels, in relation to power plant boilers, that is used in waste boilers. This means that both the efficiency to electricity and the ratio between electricity and heat production can be increased, in relation to waste incineration. Improvements in performance during the time period in question require that initiatives are taken and that e.g. gas turbine manufacturers participate actively. The probability for this development is more difficult to assess. For BIG-ICE, the technology is assessed to reach 35-40 % electricity efficiency at the end of the period, i.e. 2025-2030, and the investment cost for bigger plants can be just below that of comparable conventional steam plants, perhaps 3 000 Euro/kWe for a complete plant. Completely commercial technology can be expected at the beginning of the 2020's. For BIG-CC the corresponding assessment is 45-50 % and 2500-3000 Euro/kWe. The route to commercial technology is longer in this case and plants on near commercial conditions cannot be expected until the end of the 2020's.

    2015-06-01

    Status epilepticus is a common neurological emergency with considerable associated health-care costs, morbidity, and mortality. The definition of status epilepticus as a prolonged seizure or a series of seizures with incomplete return to baseline is under reconsideration in an effort to establish a more practical definition to guide management. Clinical research has focused on early seizure termination in the prehospital setting. The approach of early escalation to anaesthetic agents for refractory generalised convulsive status epilepticus, rather than additional trials of second-line anti-epileptic drugs, to avoid neuronal injury and pharmaco-resistance associated with prolonged seizures is gaining momentum. Status epilepticus is also increasingly identified in the inpatient setting as the use of extended electroencephalography monitoring becomes more commonplace. Substantial further research to enable early identification of status epilepticus and efficacy of anti-epileptic drugs will be important to improve outcomes.

    1977-12-01

    A state-of-the-art review of the processes currently being developed for the removal of nitrogen oxides (NO/sub x/) and sulfur oxides (SO/sub x/) from flue gases, and which may be applicable to coal-fired flue gas, was executed. A list of 21 promising flue gas treatment processes was assembled using information available during the first half of 1977. A detailed technical assessment of 18 of these NO/sub x/-SO/sub x/ removal processes resulted from communications with the process developers. Each detailed technical evaluation contained a process description and simplified block flow diagram, the history and status of development, the published economics, the raw material and utility requirements, the technical and environmental considerations, and the favorable and adverse characteristics for the process. The NO/sub x/-SO/sub x/ removal processes were classified based on the type of NO/sub x/ removal employed. The most advanced types of FGT for NO/sub x/-SO/sub x/ removal are now dry selective catalytic reduction (SCR) and wet oxidation-absorption-reduction. However, all of the processes require further development on larger scale tests and with coal-fired flue gas. Also, the economics included in this report are subject to revision as the processes are examined at larger facilities in the future.

It gives an overview of the production, transmission and consumption of electricity in the Norwegian society, and shows energy use for various purposes and the relationship between energy and the environment. Norway is the sixth largest hydropower producer in the world and, together with Iceland the highest portion of renewable electricity production of all countries in Europe. In comparison, is about 17 percent of all electricity in the EU based on renewable resources. In Sweden, renewable energy resources account for about half of all electricity production, while the corresponding share in Denmark is about 29 percent. The good supply of water power has contributed to the fact that Norway has a consumption pattern that differs from the countries around us. (AG)

    The electrostatic precipitators (EP) in service of coal-firing power plants commonly have problem of failing to reach the standard set for smoke emission. It is believed from analysis that the most fundamental cause leading to said problems is unreasonable design of EP's parameters,especially the small specific dust collection area (SDCA). Regarding to commonly used coal sort for power gener-ation,under condition of reasonably choised SDCA,the concentration of smoke emission at exit of EP can satisfy the requirement of the new emission standard , being lower than 5 0 mg / m3. The range of SDCA is recommended as follows:l, if the concentration of smoke emission to be less than 100 mg/m3 ,under condition of conventional coal sort, the SDCA should≥110 m2 (m3/s) ; under condition of diffi-cultly collecting coal sort, the SDCA should≥150 m2 (m3/s);2. If the concentration of smoke emission to be less than 50 mg/m3 ,under condition of conventional coal sort,the SDCA must≥125 m2 (m3/s);under condition of special coal sorts,the SDCA must≥180 m2 (m3/s).%燃煤电厂现役电除尘器普遍存在烟尘排放不达标的问题,分析认为电除尘器关键参数设计不合理,尤其比集尘面积小是造成这种问题的最根本原因.在比集尘面积选择合理的情况下,电除尘器出口烟尘排放浓度达到低于50 mg/m3的新排放标准时,要求推荐的比集尘面积范围如下:(1)烟尘排放浓度小于100 mg/m3、常规煤种情况下,比集尘面积≥110 m3/(m3/s);难收集煤种情况下,比集尘面积≥150 m2/(m3/s).(2)烟尘排放浓度小于50 mg/m3、常规煤种情况下,比集尘面积≥125 m2/(m3/s);特殊煤种情况下,比集尘面积≥180 m2/(m3/s).

  19. Normative Power

    DEFF Research Database (Denmark)

    The social sciences have many different understandings of ‘normative power', but in European Union (EU) studies normative power has three particular meanings. The first meaning of normative power is its emphasis on normative theory, that is, how we judge and justify truth claims in social science....... The second meaning of normative power is as a form of power that is ideational rather than material or physical. The third meaning of normative power is as a characterisation of an ideal type of international actor. Empirical studies of normative forms of power have analysed both the causal and constitutive...... effects of EU relations with the world in areas ranging from inter-regional relations, through traditional diplomacy, to environmental politics. Research areas of particular interest include the study of the interplay between physical, material and normative forms of power, as well as the constitutive...

    The global electrical energy consumption is still rising and there is an urgent demand to increase the power capacity. It is expected that the power capacity has to be doubled within 20 years. The production, distribution and use of energy should be as efficient as possible and incentives to save...... energy at the end-user should also be set up. Deregulation of energy has in the past lowered the investment in larger power plants, which means the need for new electrical power sources will be high in the near future. Two major technologies will play important roles to solve the future problems. One...... is to change the electrical power production sources from the conventional, fossil (and short term) based energy sources to renewable energy resources. The other is to use high efficient power electronics in power generation, power transmission/distribution and end-user application. This paper discuss the most...

    汞的累积性及高毒性使其成为了未来主要的污染物控制对象之一,目前较为成熟的活性炭喷射技术平均汞脱除率能够达到80%~98%,但极高的运行成本仍然难于达到大范围商业推广的要求。飞灰作为燃煤电站的废弃物,成本极低,且同样具备汞捕集能力,某些飞灰的汞脱除能力甚至能够达到商业活性炭级别。本文对目前影响飞灰汞脱除率的研究进行了综述。综合讨论了烟气气氛、煤炭类型、飞灰含碳量、飞灰岩相结构等多种因素对飞灰汞脱除率的影响。明确了飞灰脱汞技术的可行性,以及未来亟待解决的问题。%Mercury is toxic and easy to enrichment,it is one of the main pollutants control object in the future. Al-though,as a relatively mature technique, the activated carbon injection technologycan make the average mercury removal rate reach to 80%~98%, but high operating costs becamethe restrictionfor large-scale business development. Fly ash, as the waste of coal-fired power plant,not only is low cost, butalso with mercury capture capability. The mercury removal capacityof certain fly ashes can even reach commercial activated carbon levels. Currentlyresearcheson mercury removal rate of fly ash were reviewed in this paper. Theinfluence of gas atmosphere, coal type, the carbon content of fly ash, fly limestone phase structure and other factors on the fly ash mercury removal rate was discussed in this article. Results showed that fly ash as ab-sorbent is feasible, but still some difficulties should be solved.

    Status inequalities seem to play a fairly big role in creating inequalities in health. This article assumes that there can be good reasons to fight status inequalities in order to reduce inequalities in health. It examines whether the neorepublican ideal of non-dominance does a better job...... as a theoretical foil for this as compared to a liberal notion of non-interference. The article concludes that there is a prima facie case for incorporating non-dominance into our thinking about public health, but that it needs to go hand in hand with a more traditional liberal ideal of non-interference....

    In order to lengthen service life of denitration catalyst in thermal power plant,the use and life management state of deniration catalyst was introduced combining with the whole catalyst use process. The cause of catalyst poisoning was analyzed. In order to maximize catalyst effects,the choose of catalyst should take full account of actual operating parameters which were provided by manufacturer. The ammonia could clog air preheater,so the spraying value of ammonia,operating temperature,soot blower system should be controlled strict-ly. The clogging,poisoning,physical deterioration and sintering were the main reasons of catalyst deactivation. The catalyst efficiency,am-monia escape and SO2/SO3 conversion ratio could be used to check if the catalyst still had activity. There were some useful component in waste catalyst,so the waste catalyst recycling and regeneration technologies development should be strengthened.%为了延长火电厂脱硝催化剂的使用寿命,介绍了脱硝催化剂使用及寿命管理现状,结合催化剂使用全过程论述了投运前、运行中及后续维护过程中催化剂的寿命管理方法,总结了催化剂中毒原因并提出寿命管理建议。催化剂选择设计时应充分考虑催化剂厂家提供的催化剂实际运行参数,最大限度满足催化剂运行工况;催化剂运行、检修、维护过程中,要严格控制喷氨量、运行温度、吹灰系统,避免为了提高脱硝效率而增加氨逃逸,引起空气预热器堵塞等问题。堵塞、中毒、机械磨损、烧结是造成催化剂失活的主要原因,通过检测脱硝催化剂的效率、氨逃逸和SO2/SO3转化率等指标,判断催化剂是否失活,并定期进行催化剂单体的检测和脱硝系统性能测试。最后提出应加强废旧催化剂的回收处理技术,如催化剂的二次再生技术以及从废旧催化剂中提取微量元素、回收有效成分等。

    Full Text Available Figurative language, the built environment, and our perceptuo-motor experiences frequently associate social status with physical space. Linguistic references such as high status or climbing the corporate ladder, and built places such as the U.S. Capitol building link social and physical hierarchies. In three experiments we examine the source and extent of these associations by testing whether people implicitly associate abstract social status indicators with concrete representations of spatial topography (level versus mountainous land and relatively abstract representations of cardinal direction (south and north. Experiment 1 demonstrates speeded performance during an Implicit Association Test (IAT; Greenwald et al., 1998 when average social status is paired with level topography and high status with mountainous topography. Experiments 2 and 3 demonstrate a similar effect but with relatively abstract representations of cardinal direction (south and north, with speeded performance when average and powerful social status are paired with south and north coordinate space, respectively. Abstract concepts of social status are perceived and understood in an inherently spatial world, resulting in powerful associations between abstract social concepts and concrete and abstract notions of physical axes. These associations may prove influential in guiding daily judgments and actions.

  1. Lithium batteries: Status, prospects and future

    Science.gov (United States)

    Scrosati, Bruno; Garche, Jürgen

    Lithium batteries are characterized by high specific energy, high efficiency and long life. These unique properties have made lithium batteries the power sources of choice for the consumer electronics market with a production of the order of billions of units per year. These batteries are also expected to find a prominent role as ideal electrochemical storage systems in renewable energy plants, as well as power systems for sustainable vehicles, such as hybrid and electric vehicles. However, scaling up the lithium battery technology for these applications is still problematic since issues such as safety, costs, wide operational temperature and materials availability, are still to be resolved. This review focuses first on the present status of lithium battery technology, then on its near future development and finally it examines important new directions aimed at achieving quantum jumps in energy and power content.

  13. Status of the NASA Stirling Radioisotope Project

    Science.gov (United States)

    Schreiber, Jeffrey G.

    2007-01-01

    Free-piston Stirling power conversion has been considered a candidate for radioisotope power systems for space for more than a decade. Prior to the free-piston Stirling architecture, systems were designed with kinematic Stirling engines that used linkages and rotary alternators to convert heat to electricity. These systems were able to achieve long life by lightly loading the linkages; however, the live was nonetheless limited. When the free-piston configuration was initially proposed, it was thought to be attractive due to the relatively high conversion efficiency, acceptable mass, and the potential for long life and high reliability based on wear-free operation. These features have consistently been recognized by teams that have studied technology options for radioisotope space power systems. Since free-piston Stirling power conversion was first considered for space power applications, there have been major advances in three general areas of development: hardware that has demonstrated long-life and reliability, the success achieved by Stirling cryocoolers in space, and the overall developmental maturity of the technology for both space and terrestrial applications. Based on these advances, free-piston Stirling convertors are currently being developed for space power, and for a number of terrestrial applications. They commonly operate with the power, efficiency, life, and reliability as intended, and much of the development now centers on system integration. This paper will summarize the accomplishments of free-piston Stirling power conversion technology over the past decade, review the status of development with regard to space power, and discuss the challenges that remain.

  14. Renewables 2010 - Global status report

    International Nuclear Information System (INIS)

    Changes in renewable energy markets, investments, industries, and policies have been so rapid in recent years that perceptions of the status of renewable energy can lag years behind the reality. This report captures that reality and provides a unique overview of renewable energy worldwide as of early 2010. The report covers both current status and key trends. By design, the report does not provide analysis, discuss current issues, or forecast the future. Many of the trends reflect the increasing significance of renewable energy relative to conventional energy sources (including coal, gas, oil, and nuclear). By 2010, renewable energy had reached a clear tipping point in the context of global energy supply. Renewables comprised fully one quarter of global power capacity from all sources and delivered 18 percent of global electricity supply in 2009. In a number of countries, renewables represent a rapidly growing share of total energy supply-including heat and transport. The share of households worldwide employing solar hot water heating continues to increase and is now estimated at 70 million households. And investment in new renewable power capacity in both 2008 and 2009 represented over half of total global investment in new power generation. Trends reflect strong growth and investment across all market sectors-power generation, heating and cooling, and transport fuels. Grid-connected solar PV has grown by an average of 60 percent every year for the past decade, increasing 100-fold since 2000. During the past five years from 2005 to 2009, consistent high growth year-after-year marked virtually every other renewable technology. During those five years, wind power capacity grew an average of 27 percent annually, solar hot water by 19 percent annually, and ethanol production by 20 percent annually. Biomass and geothermal for power and heat also grew strongly. Much more active policy development during the past several years culminated in a significant policy milestone

    This section includes some historical background of the rise and fall and subsequent rebirth of the electric vehicle; and a brief discussion of current transportation needs, and environmental and energy utilization issues that resulted in the renewed interest in applying electrochemical energy conversion technology to electric vehicle applications. Although energy utilization has evolved to be the most significant and important issue, the environmental issue will be discussed first in this section only because of its chronological occurrence. The next part of the chapter is a review of passenger and commercial electric vehicle technology with emphasis on vehicle design and demonstrated performance of vehicles with candidate power sources being developed. This is followed by a discussion of electrochemical power source requirements associated with future electric vehicles that can play a role in meeting modern transportation needs. The last part of the chapter includes first a discussion of how to identify candidate electrochemical systems that might be of interest in meeting electric vehicle power source requirements. This is then followed by a review of the current technological status of these systems and a discussion of the most significant problems that must be resolved before each candidate system can be a viable power source.

    2004-01-01

    In addition to its medical importance as parasitic pathogen, Entamoeba has aroused people's interest in its evolutionary status for a long time. Lacking mitochondrion and other intracellular organelles common to typical eukaryotes, Entamoeba and several other amitochondrial protozoans have been recognized as ancient pre-mitochondriate eukaryotes and named "archezoa", the most primitive extant eukaryotes. It was suggested that they might be living fossils that remained in a primitive stage of evolution before acquisition of organelles, lying close to the transition between prokaryotes and eukaryotes. However, recent studies revealed that Entamoeba contained an organelle, "crypton" or "mitosome", which was regarded as specialized or reductive mitochondrion. Relative molecular phylogenetic analyses also indicated the existence or the probable existence of mitochondrion in Entamoeba. Our phylogenetic analysis based on DNA topoisomerase II strongly suggested its divergence after some mitchondriate eukaryotes. Here, all these recent researches are reviewed and the evolutionary status of Entamoeba is discussed.

  20. Health status of newcomers.

    Science.gov (United States)

    Matuk, L C

    1996-01-01

    This article presents and discusses findings on the health status of newcomers residing in Windsor, Ontario. The data are part of a larger study, which was based on the Ontario Health Survey's questionnaire. Data were collected from 548 newcomers through home visits, focus groups, mail surveys, and telephone interviews. Descriptive multivariate analyses focused on main areas in newcomers' physical and mental health status and their access to health services. The findings identified that most newcomers do not have acute, life-threatening physical problems or chronic illness. They do not experience major problems with access to health care or activity limitations. Men are happier, more satisfied with their health, and less stressed than women. This study has implications for adoption of sensitive transcultural approaches to promote newcomers' health. Special challenges lie in women's health and mental health.

  1. Status of memory loss.

    LENUS (Irish Health Repository)

    Iyer, Parameswaran Mahadeva

    2012-01-01

    A 72-year-old woman presented with first onset of seizure with no prior history of cognitive dysfunction. EEG revealed focal non-convulsive status epilepticus. MRI brain showed a left temporal non-enhancing lesion. Temporal pole biopsy showed acute neuronal necrosis and astrocyte hyperplasia together with extensive amyloid plaques and neurofibrillary tangles. Perivascular oligodendroglial hyperplasia was present. Postmortem examination revealed extensive plaque and tangle disease. Perivascular oligodendroglial hyperplasia was limited to the left temporal area. The presence of focal perivascular oligodendroglial hyperplasia in the left temporal cortex, combined with extensive plaque and tangle disease may have contributed to the focal status epilepticus in this patient. Although the presence of focal perivascular oligodendroglial hyperplasia has been reported in cases of temporal lobe epilepsy, it has not been reported as a cause of seizure in patients with Alzheimer\\'s disease previously. Further studies for clinical-pathologic correlation would be required to confirm this hypothesis.

  10. Nuclear power for tomorrow

    International Nuclear Information System (INIS)

    The evolution of nuclear power has established this energy source as a viable mature technology, producing at comparative costs more than 16% of the electricity generated world-wide. After outlining the current status of nuclear power, extreme future scenarios are presented, corresponding respectively to maximum penetration limited by technical-economic characteristics, and nuclear phase-out at medium term. The situation is complex and country specific. The relative perception of the importance of different factors and the compensation of advantages vs. disadvantages, or risk vs. benefits, has predominant influence. In order to proceed with an objective and realistic estimate of the future role of nuclear power worldwide, the fundamental factors indicated below pro nuclear power and against are assessed, including expected trends regarding their evolution: Nuclear safety risk; reduction to levels of high improbability but not zero risk. Reliable source of energy; improvements towards uniform standards of excellence. Economic competitiveness vs. alternatives; stabilization and possible reduction of costs. Financing needs and constraints; availability according to requirements. Environmental effects; comparative analysis with alternatives. Public and political acceptance; emphasis on reason and facts over emotions. Conservation of fossil energy resources; gradual deterioration but no dramatic crisis. Energy supply assurance; continuing concerns. Infrastructure requirements and availability; improvements in many countries due to overall development. Non-proliferation in military uses; separation of issues from nuclear power. IAEA forecasts to the year 2005 are based on current projects, national plans and policies and on prevailing trends. Nuclear electricity generation is expected to reach about 18% of total worldwide electricity generation, with 500 to 580 GW(e) installed capacity. On a longer term, to 2030, a stabilized role and place among available viable

    Orlando, D. A.; Camper, L.; Buckley, J.; Pogue, E.; Banovac, K.

    2003-02-24

    On July 21, 1997, the U.S. Nuclear Regulatory Commission (NRC) published the final rule on Radiological Criteria for License Termination (the License Termination Rule or LTR) as Subpart E to 10 CFR Part 20. NRC regulations require that materials licensees submit Decommissioning Plans to support the decommissioning of its facility if it is required by license condition, or if the procedures and activities necessary to carry out the decommissioning have not been approved by NRC and these procedures could increase the potential health and safety impacts to the workers or the public. NRC regulations also require that reactor licensees submit Post-shutdown Decommissioning Activities Reports and License Termination Plans to support the decommissioning of nuclear power facilities. This paper provides an update on the status of the NRC's decommissioning program that was presented during WM'02. It discusses the staff's current efforts to streamline the decommissioning process, current issues being faced in the decommissioning program, such as partial site release and restricted release of sites, as well as the status of the decommissioning of complex sites and those listed in the Site Decommissioning Management Plan. The paper discusses the status of permanently shut-down commercial power reactors and the transfer of complex decommissioning sites and sites listed on the SDMP to Agreement States. Finally the paper provides an update of the status of various tools and guidance the NRC is developing to assist licensees during decommissioning, including an effort to consolidate and risk-inform decommissioning guidance.

  15. NRC quarterly [status] report

    International Nuclear Information System (INIS)

    This report covers the third quarter of calendar year 1987. The NRC licensing activity during the period of this report included the issuance of a full-power license for Beaver Valley 2 on August 14, 1987, and operating license restricted to five percent power for South Texas Unit 1 on August 21, 1987. Additional licensing delay for Shoreham is projected due to complex litigation. Also, licensing delay may occur for Comanche Peak Unit 1, because the duration of the hearing is uncertain. Although a license authorizing fuel loading and precriticality testing for Seabrook Unit 1 has been issued, there is a projected delay for low-power licensing. Full-power licensing for Seabrook Unit 1 will be delayed due to offsite emergency preparedness issues. The length of the delay is not known at this time. With the exception of Seabrook and Shoreham, regulatory delays in this report are not impacted by the schedules for resolving off-site emergency preparedness issues

    A power system includes a prime mover, a transmission, and a fluid coupler having a selectively engageable lockup clutch. The fluid coupler may be drivingly connected between the prime mover and the transmission. Additionally, the power system may include a motor/generator drivingly connected to at least one of the prime mover and the transmission. The power-system may also include power-system controls configured to execute a control method. The control method may include selecting one of a plurality of modes of operation of the power system. Additionally, the control method may include controlling the operating state of the lockup clutch dependent upon the mode of operation selected. The control method may also include controlling the operating state of the motor/generator dependent upon the mode of operation selected.

    Defective blood coagulation resulting from excessive procoagulant activity often leads to thrombotic disorders such as stroke and myocardial infarction. A variety of oral and injectable anticoagulant drugs are prescribed to prevent or treat life-threatening thrombosis. However, due to bleeding complications often associated with anticoagulant treatment, routine monitoring and accurate dosing of anticoagulant therapy is imperative. We have developed Optical thromboelastography (OTEG), a non-contact approach that utilizes a drop of whole blood to measure blood coagulation status in patients. Here, we demonstrate the capability of OTEG for rapidly monitoring anticoagulation in whole blood samples. OTEG monitors coagulation status by assessing changes in blood viscosity from temporal intensity fluctuations of laser speckle patterns during clotting. In OTEG a blood drop is illuminated with coherent light and the blood viscosity is measured from the speckle intensity autocorrelation curve, g2 (t). The metrics, clotting time (R+k), clot progression (angle) and maximum clot stiffness (MA) are then extracted. The aim of the current study was to evaluate the accuracy of OTEG in assessing anticoagulation status of common anticoagulants including heparin, argatroban and rivaroxaban status. A dose-dependent prolongation of R+k was observed in anticoagulated blood, which closely corresponded with standard-reference Thromboelastography (TEG) (r 0.87-0.99, P>0.01 for all cases). OTEG angle was unaltered by anticoagulation whereas TEG angle presented a dose-dependent diminution probably linked to clot rupture. In both OTEG and TEG, MA was unaffected by heparin, argatroban or rivaroxaban. We conclude that OTEG can accurately monitor anticoagulation status following treatment, potentially providing a powerful tool for routine monitoring of patients in the doctor's office or in the home setting.

  1. Current Status of RENO Experiment

    International Nuclear Information System (INIS)

    The RENO (Reactor Experiment for Neutrino Oscillation) is under construction to measure the value of the smallest and unknown neutrino mixing angle θ13. The experiment will compare the measured fluxes of electron antineutrinos at two detectors located at 290 m and 1.4 km distances from the center of the Yonggwang nuclear reactors in Korea, with world-second largest thermal power output of 16.4 GW. Construction of experimental halls and access tunnels for both near and far detector sites was completed in early 2009. The detectors are near completion, and data-taking is planned to start in mid 2010. An expected number of observed antineutrino is roughly 510 and 80 per day in the near detector and far detector, respectively. An estimated systematic uncertainty associated with the measurement is less than 0.6%, and an expected statistical error is about 0.3%. With three years of data, the experiment will search for the mixing angle values of sin2(2θ13) down to 0.02 in 90% C.L. limit. In this talk, the construction status will be presented. (author)

    2010-01-01

    Full Text Available Introduction. Convulsive status epilepticus is the most urgent neurological medical emergency in children. Generalized convulsive status epilepticus is the most common and life-threatening type of status epilepticus. It is not a syndrome in the same sense as febrile convulsions, benign rolandic epilepsy, and infantile polymorphic epilepsy. These latter disorders have a tight age frame, seizure semiology, and a reasonably predictable outcome. Episodes of convulsive status epilepticus can occur in each: occasionally in symptomatic and febrile convulsions, and Lennox Gastaut syndrome, rarely in benign rolandic epilepsy, and West syndrome. Etiology of convulsive status epilepticus. Status epilepticus has many causes, which vary depending on the age and patient population. Convulsive status epileptucus continues to be associated with significant neurological morbidity and mortality, with different hazards and outcome. Although the outcome is dependent on etiology, it is known that appropriate early management may reduce mortality and some of the morbidity associated with convulsive status epilepticus. Discussion. Status epilepticus is a disorder in which the mechanisms attempting at terminating the seizure fail. Continued convulsive activity in convulsive status epilepticus results in decompensation of all organs and systems, thus being life threatening. Seizure activity in convulsive status epilepticus is associated with neuronal damage. The aim should be to halt this activity urgently, using, ideally, a 100% effective drug, administered quickly, without compromising the consciousness level or producing other negative effects on cardiovascular, respiratory function or other unexpected effects.

    We introduce a novel communication strategy for DC Micro Grids (MGs), termed power talk, in which the devices communicate by modulating the power levels in the DC bus. The information is transmitted by varying the parameters that the MG units use to control the level of the common bus voltage......, while it is received by processing the bus measurements that units perform. This implies that the communication does not require a dedicated modem, but instead it is piggybacked on top of the power electronics. The communication is challenged by the random fluctuations of the voltage level due...

Each VSC transmits information by changing the control parameters, and receives information by observing the local...... output power. By using common coding schemes, which transform the DC MGs in some familiar communication channels, some important communication challenges can be addressed, such as random load variations and VSCs switching, as it do not need a separate communication channel.

    International Nuclear Information System (INIS)

    This article expresses the view that nuclear power is the only logical alternative to dwindling oil supplies, and that blame for failure to implement the nuclear power programme can be placed on the environmentalists, the media and political leaders who have been frightened by anti-nuclear demonstrations and anticipated media reaction to their decisions. President Carter and others have looked upon nuclear power as a last resort, but it is shown here to be more abundant, cheaper, cleaner, and safer than all other currently available sources of energy.

    All 115 kindergarteners in a suburban school district were evaluated with an extensive battery of intellectual, academic, social, and adaptive behavior measures to determine the predictive significance of single-parent status on school-entry competencies. Divorce was found to add significant amounts of independent variance to the socioeconomic status predictions of several criteria, specifically those relating to social and academic competence. Both single-parent status and SES were more powerful predictors than other family background, developmental history, and health variables.

    Scleromyxedema is a rare dermatologic disorder, characterized by erythematous or yelowish lichenoid waxy papules. Neurological manifestations are rare but wel-recognized. A 51-year-old woman, diagnosed with scleromyxedema, was admitted to the hospital with status epilepticus, caused by brain lesions, as disclosed in a brain magnetic resonance imaging (MRI). The patient was treated with anticonvulsants and corticosteroids and gradualy recovered fuly. A complete remission of the lesions was shown in a folow-up brain MRI. In cases with scleromyxedema and the presence of neurological manifestations, we need to pay attention to central nervous system involvement, especialy when combined with brain MRI lesions, and treat the patient appropriately.

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings.

    Power Preservation (Abstract) In the 17th century, just as today, coalitions needed ‘lead nations’. This was assumed to be a power with great military and economic potentials, and Denmark endeavoured to act as such a leader in the Thirty Years War from 1626 to 28. The results were not encouraging...... in the military field and they were disastrous as far as fiscal matters were concerned. Sweden took over the leadership of the protestant side and she took over Denmark’s place amongst the great powers of the Baltic Region. From that time onwards, Danish influence and options on the international stage gradually...... declined. Thus, Denmark of the 17th century is not to be counted amongst the great powers, but since Christian V’s accession to the throne in 1670 Denmark-Norway has developed into one of Europe’s most highly militarised states. Apart from a permanently combat ready navy, the country maintains a standing...

    Energy Technology Data Exchange (ETDEWEB)

    Singh, Prabhakar; Minh, Nguyen Q.

    2004-08-01

    In its most common configuration, solid oxide fuel cell (SOFC) uses an oxygen ion conducting ceramic electrolyte membrane, perovskite cathode and nickel cermet anode electrode. Cells operate in the 600-1000 C temperature range and utilize metallic or ceramic current collectors for cell-to-cell interconnection. Recent development in engineered electrode architectures, component materials chemistry, cell and stack designs and fabrication processes have led to significant improvement in the electrical performance and performance stability as well as reduction in the operating temperature of such cells. Large kW-size power generation systems have been designed and field demonstrated. This paper reviews the status of SOFC power generation systems with emphasis on cell and stack component materials, electrode reactions, materials reactions and corrosion processes

    Describes the organisation of the Malaysian electric power industry and the role of natural gas and coal in power generation in the country. At present, electricity is produced by three utilities: Tenaga Nasional Berhad (TNB) which was fully privatised in May 1992 with the Government holding about 73% of the equity, Sarawak Electricity Supply Corporation (SESCO) which the Government plans to privatise soon, and Sabah Electricity Board (SEB). These have installed capacities of 7000 MW, 400 MW and 350 MW, respectively. Five independent power producers have been given licences to build, own and operate power plants with a total installed capacity of 4000 MW. Natural gas is expected to account for about 72% of Malaysia's power generating fuel by the year 2010, compared to about 50% at present. Malaysia currently has only one coal-fired plant, but its expansion is in the final stage of contract awards. A number of small capacity coal-fired plants are being planned for Sabah and Sarawak where the bulk of Malaysia's coal resources are located. 3 figs., 1 photo.

  19. Status of advanced light water reactor designs 2004

    International Nuclear Information System (INIS)

    The report is intended to be a source of reference information for interested organizations and individuals. Among them are decision makers of countries considering implementation of nuclear power programmes. Further, the report is addressed to government officials with an appropriate technical background and to research institutes of countries with existing nuclear programmes that wish to be informed on the global status in order to plan their nuclear power programmes including both research and development efforts and means for meeting future. The future utilization of nuclear power worldwide depends primarily on the ability of the nuclear community to further improve the economic competitiveness of nuclear power plants while meeting stringent safety requirements. The IAEA's activities in nuclear power technology development include the preparation of status reports on advanced reactor designs to provide all interested IAEA Member States with balanced and objective information on advances in nuclear plant technology. In the field of light water reactors, the last status report published by the IAEA was 'Status of Advanced Light Water Cooled Reactor Designs: 1996' (IAEA-TECDOC-968). Since its publication, quite a lot has happened: some designs have been taken into commercial operation, others have achieved significant steps toward becoming commercial products, including certification from regulatory authorities, some are in a design optimization phase to reduce capital costs, development for other designs began after 1996, and a few designs are no longer pursued by their promoters. With this general progress in mind, on the advice and with the support of the IAEA Department of Nuclear Energy's Technical Working Group on Advanced Technologies for Light Water Reactors (LWRs), the IAEA has prepared this new status report on advanced LWR designs that updates IAEA-TECDOC-968, presenting the various advanced LWR designs in a balanced way according to a common outline

    Inspired by the growing attention to the politics of comedy in the United States and elsewhere, this article asks what it would mean to think critically about relations of power mobilized through cheerfulness, humor, and laughter. The article shows that existing answers to this question are tainted...... by skepticism about the enduring contributions of comic acts, and it then goes on to suggest that we turn to an alternative trajectory in democratic theory, one that encourages us to focus on the empowering and pluralizing potential embedded in what I name “comic power.” The wager is that attention...... to the potential embedded in this power can give us new traction on the conditions of democracy more broadly understood. To show this, the article draws on two rarely paired resources—Spinoza’s philosophy of immanence and Dave Chappelle’s critique of racial discrimination—placing both of them in conversation...

    The status of French reactors is reviewed. The ORPHEE and RHF reactors can not be operated with a LEU fuel which would be limited to 4.8 g U/cm{sup 3}. The OSIRIS reactor has already been converted to LEU. It will use U{sub 3}Si{sub 2} as soon as its present stock of UO{sub 2} fuel is used up, at the end of 1994. The decision to close down the SILOE reactor in the near future is not propitious for the start of a conversion process. The REX 2000 reactor, which is expected to be commissioned in 2005, will use LEU (except if the fast neutrons core option is selected). Concerning the end of the HEU fuel cycle, the best option is reprocessing followed by conversion of the reprocessed uranium to LEU.

    The development of the Advanced Life Support (ALS) Sizing Analysis Tool (ALSSAT) using Microsoft(Registered TradeMark) Excel was initiated by the Crew and Thermal Systems Division (CTSD) of Johnson Space Center (JSC) in 1997 to support the ALS and Exploration Offices in Environmental Control and Life Support System (ECLSS) design and studies. It aids the user in performing detailed sizing of the ECLSS for different combinations of the Exploration Life support (ELS) regenerative system technologies. This analysis tool will assist the user in performing ECLSS preliminary design and trade studies as well as system optimization efficiently and economically. The latest ALSSAT related publication in ICES 2004 detailed ALSSAT s development status including the completion of all six ELS Subsystems (ELSS), namely, the Air Management Subsystem, the Biomass Subsystem, the Food Management Subsystem, the Solid Waste Management Subsystem, the Water Management Subsystem, and the Thermal Control Subsystem and two external interfaces, including the Extravehicular Activity and the Human Accommodations. Since 2004, many more regenerative technologies in the ELSS were implemented into ALSSAT. ALSSAT has also been used for the ELS Research and Technology Development Metric Calculation for FY02 thru FY06. It was also used to conduct the Lunar Outpost Metric calculation for FY08 and was integrated as part of a Habitat Model developed at Langley Research Center to support the Constellation program. This paper will give an update on the analysis tool s current development status as well as present the analytical results of one of the trade studies that was performed.

    As we approach the 22nm half-pitch (hp) technology node, the industry is rapidly running out of patterning options. Of the several lithography techniques highlighted in the International Technology Roadmap for Semiconductors (ITRS), the leading contender for the 22nm hp insertion is extreme ultraviolet lithography (EUVL). Despite recent advances with EUV resist and improvements in source power, achieving defect free EUV mask blank and enabling the EUV mask infrastructure still remain critical issues. To meet the desired EUV high volume manufacturing (HVM) insertion target date of 2013, these obstacles must be resolved on a timely bases. Many of the EUV mask related challenges remain in the pre-competitive stage and a collaborative industry based consortia, such as SEMATECH can play an important role to enable the EUVL landscape. SEMATECH based in Albany, NY is an international consortium representing several of the largest manufacturers in the semiconductor market. Full members include Intel, Samsung, AMD, IBM, Panasonic, HP, TI, UMC, CNSE (College of Nanoscience and Engineering), and Fuller Road Management. Within the SEMATECH lithography division a major thrust is centered on enabling the EUVL ecosystem from mask development, EUV resist development and addressing EUV manufacturability concerns. An important area of focus for the SEMATECH mask program has been the Mask Blank Development Center (MBDC). At the MBDC key issues in EUV blank development such as defect reduction and inspection capabilities are actively pursued together with research partners, key suppliers and member companies. In addition the mask program continues a successful track record of working with the mask community to manage and fund critical mask tools programs. This paper will highlight recent status of mask projects and longer term strategic direction at the MBDC. It is important that mask technology be ready to support pilot line development HVM by 2013.

    The Mars 2020 (M2020) flight system consists of a cruise stage; an entry, descent and landing system (EDL); and a Radioisotope Thermoelectric Generator (RTG) powered roving science vehicle that will land on the surface of Mars. The M2020 Mission is designed to investigate key question related to the habitability of Mars and will conduct assessments that set the stage for potential future human exploration of Mars. Per its Program Level Requirements, the project will also acquire and cache samples of rock, regolith, and/or procedural "blank" samples for possible return to Earth by a subsequent mission. NASA has assigned the M2020 Mission as a Category V Restricted Earth Return due to the possible future return of collected samples. As indicated in NPR8020.12D, Section 5.3.3.2, the outbound leg of a Category V mission that could potentially return samples to Earth, Mars 2020 would be expected to meet the requirements of a Category IVb mission. The entire flight system is subject to microbial reduction requirements, with additional specific emphasis on the sample acquisition and caching. A bioburden accounting tool is being used to track the microbial population on the surfaces to ensure that the biological cleanliness requirements are met. Initial bioburden estimates based on MSL heritage allows M2020 to gauge more precisely how the bioburden is allocated throughout each hardware element. Mars 2020 has completed a Planetary Protection Plan with Planetary Implementation Plans at a mature draft form. Planetary protection sampling activities have commenced with the start of flight system fabrication and assembly. The status of the Planetary Protection activities will be reported.

    The technology advancement to high-power beams has also given birth to new technologies. That class of Free Electron Lasers that employs rf linacs, synchrotrons, and storage rings - although the use the tools of High Energy Physics (HEP) - was developed well behind the kinetic energy frontier. The induction linac, however, is something of an exception; it was born directly from the needs of the magnetic fusion program, and was not motivated by a high-energy physics application. The heavy-ion approach to inertial fusion starts with picking from the rich menu of accelerator technologies those that have, ab initio, the essential ingredients needed for a power plant driver: multigap acceleration - which leads to reliability/lifetime; electrical efficiency; repetition rate; and beams that can be reliably focused over a suitably long distance.

    1998-12-31

    For most of its century-long history, electricity was a natural monopoly, due in part to the excessive cost of the necessary infrastructure. In the past decade, however, politics have pushed the industry toward competition and consumer choice. At the same time, technology has been developed that allows consumers to choose their electricity supplier and to track the flow of power through the various grids and lines. In her new book, Power Branding, author and industry expert Ann Chambers examines marketing and branding of electricity -- what it is, how it`s done, what its benefits are for electric utilities, marketers, and even natural gas companies allied with the utilities. She surveys industry leaders who have already taken a dive into the ocean of marketing and offers lessons drawn from their experiences. She also takes a look at other formerly regulated industries -- airlines, telephone, natural gas -- and describes how their rebirth as free-market industries may affect the course of the electric utility industry`s experience. The contents include: Introduction; Basics of branding: Brand image; Value-added services; Southern Company; Duke Energy; UtiliCorp/EnergyOne/Aquila--big and brand; Engage energy; Florida Power and Light Co.; Enron; Convergence; Lessons from the natural gas industry; Lessons from other industries; Conclusion; Resources; Glossary of branding, marketing and Btu convergence; and Major federal legislation affecting the electric power industry.

    Link, Bruce G; Phelan, Jo

    2014-02-01

    When people have an interest in keeping other people down, in or away, stigma is a resource that allows them to obtain ends they desire. We call this resource "stigma power" and use the term to refer to instances in which stigma processes achieve the aims of stigmatizers with respect to the exploitation, control or exclusion of others. We draw on Bourdieu (1987, 1990) who notes that power is often most effectively deployed when it is hidden or "misrecognized." To explore the utility of the stigma-power concept we examine ways in which the goals of stigmatizers are achieved but hidden in the stigma coping efforts of people with mental illnesses. We developed new self-report measures and administered them to a sample of individuals who have experienced mental illness to test whether results are consistent with the possibility that, in response to negative societal conceptions, the attitudes, beliefs and behaviors of people with psychosis lead them to be concerned with staying in, propelled to stay away and induced to feel downwardly placed - precisely the outcomes stigmatizers might desire. Our introduction of the stigma-power concept carries the possibility of seeing stigmatizing circumstances in a new light. PMID:24507908

Attempts are made to systematize the didactic knowledge and identify its components and structure. Didactic concepts are classified in accordance with its objects: teaching process by the whole, its individual components or educative process aspects that enable to form definite teaching views, studying it from the specific positions. The author singles out holistic-didactic, component and aspect concepts; and specifies the concept of didactic systems and models with its hierarchy. The author highlights the didactic knowledge increment.

    Full Text Available European societies are undergoing deep changes as a result of globalization and the international financial crisis that began in 2007. These changes affect the class structure to the extent that these societies suffer an impact on the occupational structure and consume pattern. From the data of Eurobarometer we studied the state of social mobility in the European Union. Comparing the subjective status between 2009 and 2012, we observed divergent movements in European societies. Some societies experimented upward mobility while others just the opposite. We conclude that exists an increasing gap between European societies. To consider the effects of these changes on the status structures a structural model has been tested, exploring the relationship between social class, status and power in European societies. We conclude a statistically significant effect of social class and status on the consciousness perceived to possess more or less power. Two dimensions measure power: “political alienation” and “economic alienation”.

Possible applications for high-power nuclear electric propulsion include orbit raising and maneuvering of large space platforms, lunar and Mars cargo transport, asteroid rendezvous and sample return, and robotic and piloted planetary missions, while lower power radioisotope electric propulsion could significantly enhance or enable some future robotic deep space science missions. This paper provides an overview of recent US high-power electric thruster research programs, describing the operating principles, challenges, and status of each technology. Mission analysis is presented that compares the benefits and performance of each thruster type for high priority NASA missions. The status of space nuclear power systems for high-power electric propulsion is presented. The paper concludes with a discussion of power and thruster development strategies for future radioisotope electric propulsion systems.

    ANAIS experiment will look for dark matter annual modulation with large mass of ultra-pure NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC), aiming to confirm the DAMA/LIBRA positive signal in a model-independent way. Two 12.5 kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. Present status of ANAIS detectors background and general performance is summarized; in particular, thanks to the high light collection efficiency prospects of lowering the threshold down to 1 keVee are reachable. Crystal radiopurity goals are fulfilled for 232Th and 238U chains and 40K activity, although higher than original goal, could be accepted; however, high 210Pb contamination out-of-equilibrium has been identified. More radiopure detectors are being built by Alpha Spectra. The ongoing high quantum efficiency PMT tests and muon veto characterization are also presented. Finally, the sensitivity of the experiment for the annual modulation in the WIMP signal, assuming the already achieved threshold and background in ANAIS-25 is shown. Further improvement should be achieved by reducing both threshold and background, as expected.

    The Status of Glueballs is presented considering that most popular candidates from among the isoscalars in the J{sup PC} = 0{sup ++}, 0{sup {minus}+} and 2{sup ++} channels. It is shown that in the 0{sup ++} channel the f{sub 0}(1720) which was discovered earlier (the S*{prime}(1720)) at BNL is highly likely the same state as the SLAC {theta}(1720) now that its spin has been found to be 0 instead of the 2 claimed for a long period. In the {sup ++} channel there is likely a complex of 2-3 states {zeta}/{eta}(1280), {lambda}/{eta}(1420) and {iota}/{eta}(1520) involving at least one extra isosclar. In the 2{sup ++}, the g{sub T}(2010), g{sub T}{prime}(2300) and g{sub T}{double_prime}(2340) {phi}{phi} states found in {pi}{sup {minus}} p {yields} {phi}{phi}n (OZI forbidden glueball filter channel) strikingly, approximately, completely break the OZI suppression and comprise within the errors all the {phi}{phi} cross-section. The only viable explanation of these states in the context of QCD is that they are produced by 1-3 primary 2{sup ++} glueballs. All alternate explanations in the past 15 years have failed.

  15. Biosimilar drugs: Current status.

    Biologic products are being developed over the past three decades. The expiry of patent protection for many biological medicines has led to the development of biosimilars in UK or follow on biologics in USA. This article reviews the literature on biosimilar drugs that covers the therapeutic status and regulatory guidelines. Appraisal of published articles from peer reviewed journals for English language publications, search from PubMed, and guidelines from European Medicines Agency, US Food Drug Administration (FDA) and India were used to identify data for review. Literature suggest that biosimilars are similar biological products, i.e., comparable but not identical to the reference product, are not generic version of innovator product and do not ensure therapeutic equivalence. Biosimilars present more challenges than conventional generics and marketing approval is also more complicated. To improve access, US Congress passed the Biologics Price Competition and Innovation act 2009 and US FDA allowed "abbreviated pathway" for their approval. U.S law has defined new standards and terms and EMA scientific guidelines have also set detailed approval standards. India being one of the most preferred manufacturing destinations of biosimilars, there is a need for stringent safety and regulatory guidelines. The New India Guidelines "Draft Guidelines on Similar Biologics were announced in June 2012, by Department of Biotechnology at Boston bio and available online. PMID:25143877

    According to article 6 of the French law from February 10, 2000 relative to the modernization and development of the electric public utility, the manager of the public power transportation grid (RTE) has to produce, at least every two years and under the control of the French government, a pluri-annual estimated status. Then, the energy ministry uses this status to prepare the pluri-annual planning of power production investments. The estimated status aims at establishing a medium- and long-term diagnosis of the balance between power supply and demand and at evaluating the new production capacity needs to ensure a durable security of power supplies. The hypotheses relative to the power consumption and to the evolution of the power production means and trades are presented in chapters 2 to 4. Chapter 5 details the methodology and modeling principles retained for the supply-demand balance simulations. Chapter 6 presents the probabilistic simulation results at the 2006, 2010 and 2015 prospects and indicates the volumes of reinforcement of the production parks which would warrant an acceptable level of security. Chapter 7 develops the critical problem of winter demand peaks and evokes the possibilities linked with demand reduction, market resources and use of the existing park. Finally, chapter 8 makes a synthesis of the technical conclusions and recalls the determining hypotheses that have been retained. The particular situations of western France, of the Mediterranean and Paris region, and of Corsica and overseas territories are examined in chapter 9. The simulation results for all consumption-production scenarios and the wind-power production data are presented in appendixes. (J.S.)

  17. Pulsed power

    International Nuclear Information System (INIS)

    Options for EBFA-I were narrowed as data became available from Proto II, MITE and power flow research. The solid dielectric capacitors proposed for intermediate stores have been eliminated for EBFA because of low reliability. Water capacitors based on data from Proto II and Hydra will be used on EBFA. Improved SF-6 switching data from Proto II shows that present parameters are adequate for EBFA. A switch jitter of 3 ns with reliability exceeding 0.986 was demonstrated. Proto II has achieved the design output and is now a user oriented accelerator. Several desirable features of the disc accelerator were proven. Initial magnetic insulation experiments on a 1.5 m-long-triplate show small energy and power losses. Theoretical understanding of magnetic insulation was greatly enhanced and agreement between projections and experiment were obtained

    The question 'Do we really need nuclear power' is tackled within the context of Christian beliefs. First, an estimate is made of the energy requirements in the future and whether it can be got in conventional ways. The dangers of all the ways of supplying energy (eg coal mining, oil and gas production) are considered scientifically. Also the cost of each source and its environmental effects are debated. The consequences of developing a new energy source, as well as the consequences of not developing it, are considered. Decisions must also take into account a belief about the ultimate purpose of life, the relation of men to each other and to nature. Each issue is raised and questions for discussion are posed. On the whole the book comes down in favour of nuclear power.

    We use cooperative game theory to analyze the impact of three controversial pipeline projects on the power structure in the Eurasian trade of natural gas. Two of them, Nord Stream and South Stream, allow Russian gas to bypass transit countries, Ukraine and Belarus. Nord Stream's strategic value turns out to be huge, justifying the high investment cost for Germany and Russia. The additional leverage obtained through South Stream, in contrast, appears small. The third project, Nabucco, aims at ...
