    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

    The document gives general statistical information (by country) about electricity produced by nuclear power plants in the world in 1998, and in a table the number of nuclear reactors in operation, under construction, nuclear electricity supplied in 1998, and total operating experience as of 31 December 1998

  7. World status: nuclear power

    International Nuclear Information System (INIS)

    The nuclear power situation in 1988 in briefly reviewed. The prospects for the 1990s are then considered. Apart from the use of nuclear power to fuel spacecraft the prospects are not that bright. The European fast breeder programme is coming to a premature end with the winding down of the fast breeder research centre at Dounreay and the delay with the French programme because of the sodium leak at Superphenix. If plutonium is no longer needed to fuel the fast breeder reactors, the reprocessing of spent fuels is less attractive. However, seven new reprocessing plants are due to be commissioned in the next six years. The THORP plant in Britain may be affected by the privatization plans for the electricity supply industry. Decommissioning and waste storage/disposal are issues which will have to be resolved in the 1990s. The risk of accidents especially from aircraft crashes is discussed. Altogether the prospects for nuclear power are not very good. The keynote of the decade will be cleaning up rather than expansion. (U.K.)

  8. Status of fission power

    International Nuclear Information System (INIS)

    Fission energy is reviewed from the viewpoints of technology, economics, politics, manufacturers, consumers, and foreign countries. Technically, the reactor program is operating and the light water reactor industry shows signs of maturing, although recent business has been disappointing. Marketing of gas-cooled reactors depends, not on technical, but economic and political issues. Liquid metal fast breeder reactors have been demonstrated worldwide, while the gas-cooled fast breeder remains an undemonstrated option. Nuclear plants, currently costing the same as coal plants with scrubbers, are the cheapest option for utilities because most of the cost is imbedded. The defeat of nuclear initiatives in seven states indicates that public feeling is not as anti-nuclear as opponents to nuclear power claim. The harshness of last winter demonstrated the advantages of a power source that is not so sensitive to the weather for reliable operation and transport, as well as low cost energy. Other nations are proceeding to build a nuclear capability, which the U.S. may jeopardize because of concerns about the fuel cycle, nuclear waste disposal, uranium reserves, and nuclear proliferation

  16. Current status of nuclear power

    International Nuclear Information System (INIS)

    The public is aware of nuclear plants that are in serious financial trouble, but hears little about the 84 plants that operate quietly to reduce US dependence on oil. There are 25 countries producing nuclear power and nine more will join them in this decade, with the US producing about one-third of the 180 million kW generated worldwide. Public opposition and economic recession over the past 10 years have caused utilities to cancel or postpone some plant construction, but the overall financial condition of utilities is improving even though electric rates must go up to recover the capital and other fixed costs of new plants. Other countries proceeded with their nuclear programs, and will benefit from the inflation-resistance and potential for cost improvement that nuclear power offers. Utilities are concerned that underestimating the growth in demand could cause a shortfall in supply unless regulatory and legislative uncertainty can be eased

  17. The new Australian after-hours general practice incentive payment mechanism: equity for rural general practice?

    Science.gov (United States)

    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. PMID:27237945

    International Nuclear Information System (INIS)

    The SP-100 ground engineering system development project objectives, approach and status are described. The SP-100 GES development project is phase II of a three-phase program funded and directed by three United States Federal Agencies (NASA, DOD and DOE) to develop space reactor power systems for space applications in the 10 to 1000 KWe power range. The first phase of the program lasted three years, and this was completed at the end of FY 1985. SP-100 Phase I analytically and experimentally reviewed all near-term space reactor power system candidates and selected one system that best met the project mission requirements for future civilian and military space applications. The SP-100 Phase II started in fiscal year 1986 to develop the Phase I selected space reactor power system to be technically ready for space applications in the mid-to late 1990s. (author)

    1999-01-01

    BACKGROUND AND OBJECTIVES: A governmental reorganization of the after-hours general practice service in Denmark was launched in January 1992. The biggest change was the introduction of mandatory county-wide telephone triage systems staffed by general practitioners. This study assesses the effect of...... 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...

  1. After hours availability of general practitioners in Canterbury/Westland: a survey.

    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.

  3. Nuclear power in Russia: status, problems, prospects

    International Nuclear Information System (INIS)

    To solve the problem of atomic bomb, a powerful nuclear industrial complex has been established in the Soviet Union. This complex has developed a high scientific and engineering potential and enlisted the best science and engineering experts. Strict administration, rigid discipline in execution and operation, to secrecy limiting both internal and external interactions were typical of the complex which presented a state within the state with the inside divide by rigid barriers and protected from the outside by iron curtain. When the atomic bomb was designed and tested the search for a field of application for the nuclear potential available was started: nuclear power plants, nuclear power facilities for submarines and ships, nuclear aircraft and rocket engines, space nuclear facilities. Such were the conditions of forming the nuclear power in USSR. But this nuclear military complex has failed to prevent the Chelyabinsk accident which involved considerable radiological effects. The national industry could not adopt quickly the work style established in a nuclear complex and relative high technologies because of low educational and technical level and poor technological discipline. The results are known: the Chernobyl accident coincided in time with the beginning of the reconstruction of the System, the result of which was this accident. This paper describes the current status of the nuclear park, shows the problems of safety, maintenance, retrofitting, reconstruction or decommissioning. Statistical data on nuclear power in the power production program are also given

    International Nuclear Information System (INIS)

    In the context of the world-wide energy situation and the key position energy plays and will play for the economic and social development of any country, the energy demand situation up to the year 2000 is analysed. As a result, the world-wide energy demand will continue to increase, however, mainly in the developing world. Nuclear power is one of the important component in the energy mix of today and in the future. Status of nuclear power application in developing countries up to the end of the century. Any further growth of the peaceful use of nuclear power in developing countries is closely linked with the following requirements: - qualified manpower, - industrial infrastructure, - energy demand and supply assessments, - high investments, - assurance of supply of nuclear fuel and fuel cycle services, - availability of small and medium power reactors. The possible role of the IAEA in developing countries and international measures to remove some of the limitations for the peaceful use of nuclear energy in developing countries are discussed.

  5. Nuclear power worldwide: Status and outlook

    International Nuclear Information System (INIS)

    environmental constraints such as entry-into-force of the Kyoto Protocol and the European carbon trading scheme mean there is now a real financial benefit to avoiding greenhouse gas emissions, adding to the appeal of low-carbon electricity generation, including nuclear power and renewables. The complete nuclear power chain - including uranium mining, reactor construction and waste disposal - emits only 3 - 24 grams of carbon dioxide per kilowatt-hour, about the same as wind and hydro power, and well below coal, oil and natural gas, Mr. Rogner added. The IAEA provides energy planning assistance to its 145 member states. When a state considers launching a nuclear energy programme for the first time, the IAEA has established a set of milestones for it to follow. Audio Q and A with IAEA, is available here.

    Kutscher, Charles F. [National Renewable Energy Lab. (NREL), Golden, CO (United States)

    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.

    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.

The APU includes a hydrazine-powered turbine that drives a hydraulic pump and various accessories through a high-speed gearbox. The APU also features a sophisticated thermal management system designed to ensure safe and reliable operation in the various launch, orbit, reentry, and landing environments.

  12. World and domestic status nuclear power development

    International Nuclear Information System (INIS)

    Worldwide, reflecting the current recession, the demand of electric power is stagnant. Nevertheless, nuclear power development has advanced steadily mainly with LWRs, and now it is at the level of 170 million kW. In FBR development, due to the delay of technology advance and the rise of construction costs, the stage of its practical utilization appears to be postponed farther in the future. In Japan, since the first commercial nuclear power generation in July, 1966, the aggregate capacity is now 17,177,000 kW with a total of 24 power plants. Of the total 43 nuclear power plants including those for the future, 22 are BWRs and 20 are PWRs. The plant factor has increased to the level of 60 % on the average. The following matters are described: the world situation, the trend in overseas countries, and the trend in Japan. (Mori, K.)

  13. SMES based power modulator - status August 2001

    International Nuclear Information System (INIS)

    Based on a superconducting magnetic energy storage (SMES) a long-pulse klystron modulator has been designed for use in the TESLA test facility (TTF) at DESY, Hamburg. A proto-type with an output power of 25 MW is under development at Forschungszentrum Karlsruhe in cooperation with the office of engineering lbK at Karlsruhe. Including a pulse transformer (1:13/11.5), the system will deliver pulses of 130 kV or 115 kV, 1.7 ms pulse length with a flat top of ± 0.5%, at a repetition rate up to 10 Hz. This new system's main features are a highly dynamic SMES (> 100 T/s), a high current power supply (rated 27 V/2.6 kA), a switched-mode high voltage power supply (rated 14 kV/45 A), a fast thyristor power switch for 2.6 kA approx. continuous current/ 2 ms break, an IGCT power switch rated 2.6 kA/14 kV, a protection switch unit and a system control unit. This demonstration system is to serve alternatively two klystrons of 5 MW RF output or one multibeam klystron of 10 MW RF output. A significant part of the components of the system has been built. A first set of the system components had been arranged to form a model of the modulator and 1 MW pulses were generated. The next large step in the area of the power electronic part is to increase the power of this test arrangement up to 10 MW. The SMES and its cryostat have undergone initial testing. The data acquisition and control system under development at DESY has been taken over and adjusted to our computer and experimental environment. (orig.)

  19. 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

  20. 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

    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.

  5. Status and Trends of Nuclear Power World-wide

    International Nuclear Information System (INIS)

    The reliable and adequate supply of energy, especially electricity, is necessary not only for economic development but to enhance the quality of life. Nuclear power is a proven technology which already supplies about 17% of the world''s electricity generation. In 1995, seven countries produce more than 40% of their electricity from nuclear power plants: Lithuanian, France, Belgium, Sweden, Bulgaria, Slovak and Hungary. It is quite clear that many countries are heavily reliant on nuclear power and are well beyond the point where nuclear power could be replaced by some other source, so, nuclear power remains one of the few technologically proven, economically promising and environmentally benign energy sources. An important factor in the continued development of nuclear power is the extent to which nuclear generated electricity remains economically competitive. Factors such as plant availability, standardisation of systems, components and equipment, as well as the cost of equipment to meet safety and environmental regulations play also an important role in determining the relative competitiveness of nuclear power plants. Many operating organizations have already impressive results in the reduction of plant unavailability. The number of nuclear power plants currently operating with annual availability factor exceeding 85% is increasing. Good performance of some operators should establish performance targets for operators everywhere. The International Atomic Energy Agency (IAEA) has the only international and almost complete information system, the Power Reactor Information System (PRIS) with nuclear power plant status and performance data. This paper presents the current status of nuclear power plants, according to information contained in the IAEA. It discusses the plant performance indicators available in PRIS and the improvement trend in the performance of nuclear power plants based on these indicators. It also presents the future trends of nuclear power focusing

    The purpose of maximum demand power control system is to not exceed the limit of the maximum demand pre defined. To limit the maximum demand, non critical loads are controlled or disconnected when the limit is about to be exceeded. Maximum demand power generally occurs during summer; especially cooling period in each building (from 10 am to 4 pm). At this period, possible electric load should be controlled or disconnected to save electric energy while not affect the main processes. In this paper, we described maximum demand power control system designed status of PEFP.

  8. Current status of Chinese nuclear power industry and technology

    International Nuclear Information System (INIS)

    China has been carrying out active international cooperation aiming to be a country where is to be an economical super power and an advanced country in nuclear power technology by the year early 2000, and China also has begun to be recognized as the largest potential market for the construction of nuclear power plants(NPPs) expecting to construct more than thirty nuclear power units by the year 2020. China has advanced technology in the basic nuclear science including liquid metal breeder reactor technology, nuclear material, medium and small size power plants, and isotope production technology, and also China has complete nuclear fuel cycle technology. However, China still has low NPP technology. Therefore, it is expected that China may have complementary cooperative relationship with China, it is expected that Korea may have an access to the advanced Chinese nuclear science technology, and may have a good opportunity to explore the Chinese market actively exporting excellent Korean NPP technology, and further may have a good position to the neighboring Asian countries' NPP markets. From this perspective, general Chinese social status, major nuclear R and D activity status, and correct NPP and technology status have been analyzed in this report, and this report is expected to be a useful resource for cooperating with China in future. 10 tabs., 6 figs., 16 refs.

  14. 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 Earned Value Management System (EVMS) method integrates three critical elements of project management scope, cost and time management. It requires the periodic monitoring of actual expenditures and physical scope accomplishments and allows calculation of cost and schedule variances along with performance indices. It allows for casting of project cost and schedule at completion and highlights the possible need for corrective action. It is anticipated that there will be intense competition in the nuclear industry as the cost and time for nuclear power plant construction. In order to attain competitive advantages, utilizing advanced project control systems by integrating cost and time management is of great concern for practitioners. This paper is to review the status of EVMS and its effective implementation to nuclear power plant construction.

    1997-12-31

    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.

  19. 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

    International Nuclear Information System (INIS)

    The study was designed to assess the quality of out sourced after-hours computed tomography teleradiology service reports. We evaluated 1028 patients over a time period of five month in 2009/2010 (437 female, 591 male, mean age: 51 years, range: 0–97 years) who were referred either by the A and E or other in house departments from 7 pm to 8 am for different reasons. Reporting was done by a teleradiology service provider located in the UK and Australia. Reports were assessed during the routinely performed morning meeting by a panel of in house radiologists. Assessment was done by a five point agreement scale (5 = “No disagreement”, 1 = “…unequivocal potential for serious morbidity or threat to life”). In 811 (79%) patients no disagreement was found, 164 (16%) were rated as category 4, 40 (4%) as category 3 (“…likelihood of harm is low”). In 13 (1.3%) patients a decision of category 2 was made (“…strong likelihood of moderate morbidity but not threat to life”). No category 1 decision was made. As this was just a discrepancy decision, a follow up of the category 2 patients was done over a period of a maximum of 6 months. In 8 (0.8%) patients the in house reports were correct, in 2 (0.2%) patients the teleradiology service provider was right and in 3 (0.3%) patients the final diagnoses remained unclear. In conclusion there was a small rate (0.8%) of proven serious misinterpretations by the teleradiology service provider, but these were less than in comparable studies with preliminary in house staff reports (1.6–24.6%).

  1. Preliminary study on psychosomatic status of nuclear power plant operators

    International Nuclear Information System (INIS)

    Objective: To understand the operators' psychosomatic health status in nuclear power plant; and provide the scientific basis of measures for preventing and reducing mental disorders in operators. Methods: The Psychosomatic Health Battery (PSHB) was used to assess the psychosomatic health status in 109 operators who were random selected from Qinshan nuclear power plant, etc. They were tested from lie, emotional stability, liveliness, tension, apprehension, mental health, such as psychopathic deviatesuch 7 personality traits. Results: Lie < 8, all inspected groups were normal. Psychopathic deviate: 98.2% for normal group 0.9% for both of groups occurred possible mental health problems and confirmed mental health problems; Mental health: 80.7% (88/109) for fine mental health ones, 29.4% (32/109) for those with excellent mental health, 51.4% (56/109) for good mental health ones, 13.8% (15/109) for general mental health ones, 5.5% (6/109) for poor mental health ones. Age factor could influence the mean values of the factors of apprehension, tension, mental health and psychopathic deviate. Correlation analysis showed that there was a correlation between tension and psychopathic deviate (r=0.664, P<0.01), and the other correlation coefficient was between apprehension and mental health (r=-0.789, P<0.01). Conclusions: There is an excellent condition of psychosomatic health in most of the operators, however, there are still a very small percentage of psychosomatic disorders among these operators, to improve the quality of their psychosomatic health, psychological counseling should be particularly strengthened to those with problems of psychosomatic health.

  2. U.S. commercial nuclear power: a status report

    International Nuclear Information System (INIS)

    The current and forecasted status of the domestic nuclear power program is discussed in the context of the proposed National Energy Plan. Nuclear power is expected to increase its contribution to the Nation's electricity generation from 9.4 percent in 1976 to 13 percent in 1980 and 18 percent in 1985. Indigenous uranium reserves and resources appear adequate to allow a continued expansion of the national reactor system, but the annual production capacity of the domestic uranium industry must be significantly expanded to support this generating forecast. U.S. uranium enrichment capacity will also be adequate if ongoing expansion programs and the planned Portsmouth centrifuge addition are realized. However, domestic uranium demand and price, and the Administration's desire to accept new orders for enrichment services, are sensitive to Energy Research and Development Administration's enrichment contract stipulations and plant operating modes. Current U.S. policy has resulted in the deferral of the plutonium and uranium recycle option for the intermediate future, and a shift in post-reactor attention from reprocessing-recycle to unresolved programs for spent fuel storage and radioactive waste management. The comparative economics of nuclear-fueled and coal-fired generating systems vary among geographical regions, but generally, costs are so similar that modest changes in fuel or operating parameters could reverse the relative advantage of one option over the other

  3. Status of fusion power reactor design activity in JAERI

    International Nuclear Information System (INIS)

    A number of fusion power reactor design studies conducted in JAERI over the past 22 years are reviewed and the present status of reactor studies is introduced. A helium gas cooled power reactor which has a blanket with solid lithium ceramics such as Li2O for the breeding material and incolloy-800 for the structural material was proposed in 1973. This is one of the first reactor design using a lithium ceramics blanket concept. Another power reactor design called the Swimming Pool-type Tokamak Reactor (SPTR-P) was completed in 1983. In SPTR-P, the tokamak reactor is submerged in a water pool to utilize water as the shield to reduce long term radioactive waste and to achieve easy repair and maintenance. In 1990, the Steady State Tokamak Reactor (SSTR) concept was proposed as a realistic fusion reactor to be built in the near future. The major feature of SSTR is the maximum utilization of a bootstrap current in order to reduce the power required to maintain steady state operation. It is cooled by pressurized water and uses low activation ferritic steel as the structural material. A study of SSTR-2 to improve the safety and economic aspects of SSTR by replacing the water coolant by a mixture of helium gas and fine solid particles was carried out in 1992. Light yet highly heat resistant material, titanium aluminide intermetallic compound (TiAl), is used as the structural material. The net thermal efficiency larger than 40 % can be achieved with the gas-particulate mixture at 5 MPa and the outlet coolant temperature of 700degC. A concept of a Drastically Easy Maintenance (DREAM) tokamak reactor has recently been proposed. For easy replacement of blanket and divertor, a plasma configuration with high aspect ratio around 6 and a small number of torus sectoring of 12 are selected. A 1/12 torus sector is horizontally pulled out between the TF coils with a straight radial motion. It is estimated that the availability of 85 % can be achieved. (author)

    2009-09-01

    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

  7. Status of safety issues at licensed power plants

    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 has been established whereby an annual NUREG report will be published on the status of licensee implementation and NRC verification of safety issues in major NRC requirement areas. This report, the third volume of a three-volume series, addresses the status of generic safety issues (GSIs) at licensed plants. Volume 1 addressed the status of Three Mile Island Action Plan requirements and was published in March 1991. Volume 2 addressed the status of implementation and verification of unresolved safety issues and was published in May 1991. The annual NUREG report will combine these three areas in a single volume to be published in late 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. The purpose of this report is to provide a comprehensive description of the status of implementation and verification of the 34 GSIs and sub-issues that have been resolved by the NRC and involve implementation of an action or actions by licensees. This NUREG report also serves as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues up until a request for action by licensees is issued by NRC. 3 figs., 6 tabs

  10. Current Status and Future Prospects for Nuclear Power

    International Nuclear Information System (INIS)

    In the past 50 years, nuclear power has grown from a new scientific development to become a major part of the energy mix in over 30 countries. In 1998, 434 power reactors worldwide produced 2294 billion kWh of electricity, slightly up on 1997 output. Sixteen countries relied on nuclear power for 25 percent or more of their electricity. Accumulated operating experience for nuclear power plants reached over 9,000 reactor-years. In 1998, 36 nuclear power plants were under construction: 14 in Eastern Europe, 12 in the Fat East; 7 in the Middle East and South Asia, 2 in Latin America, 1 in stern Europe (France)

  11. 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

  20. 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

  2. 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

  8. Economic impacts of electricity liberalization on the status of nuclear power generation in the United States

    International Nuclear Information System (INIS)

    This paper discusses the economic impact of electricity liberalization on the status of nuclear power generation in the United States. Nuclear power plants have been treated equally with other types of power plants in the liberalized electricity market. The existing nuclear power plants were thought to be competitive in liberalized wholesale electricity market. Competitive pressure from the market also facilitated efficiency improvement among the existing nuclear power plants. Although it was difficult to build new reactor, the U.S. nuclear power generators expanded capacity through up rates. In recent years, however, nuclear power plants suffer from the decline in wholesale power prices and some of them are forced to retire early. Although there are some market design issues that could be improved to maintain the efficient nuclear power plants in competitive environment, it is now argued that some additional arrangements to mitigate the investment risks of the nuclear power plants are necessary.

  11. Status of development of robots for nuclear power generation

    International Nuclear Information System (INIS)

    In the field of checkup, inspection, maintenance and repair in nuclear power plants, remotely operated automatic devices, that is, the robots for nuclear power generation, have been adopted from the past as one of the measures to improve the reliability of equipment, to shorten the period of regular inspection and to reduce the radiation exposure dose of workers. As the proportion of nuclear power generation in electric power supply has increased, the reduction of the period and man-hour of the repair works in radioactive environment and the qualitative improvement of works have become important problems. So far, several tens of the remotely operated automatic devices for repair works have been developed and applied to PWR plants. As the range of robotization expands, the inside of existing power stations becomes overcrowded with such special devices and their control boards, therefore, it is desirable to advance the mechanization toward high performance, versatility and autonomous systems. The remotely operated automatic devices for the repair of steam generators, nuclear reactors and fuel, the automatic ultrasonic flaw detectors for pipings, the storage systems for radioactive solid wastes, unmanned forklift trucks, the submerged robots for cleaning water intake and discharge channels and so on are described.

  1. 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

  2. Nuclear power use in China. Status and development perspectives

    International Nuclear Information System (INIS)

    Over the past 10 years, the People's Republic of China has made tremendous progress in development. This is expressed, above all, in the high growth rates of the country's gross domestic product, which has more than doubled since 2000. This development was associated with a pronounced increase in energy consumption. In 2005, China, consuming 2245 million TCE, was the world's second largest energy consumer after the United States of America. China began early to develop a nuclear industry, though first especially for military purposes. Only in the seventies did China start to use nuclear power for non-military purposes and prepare nuclear power plant projects. In late 2005, nine reactors with an installed capacity of 6,934 MW were in operation. Two reactors in a 4th nuclear power plant are in an advanced state of construction. The 50.5 TWh of electricity generated (2004) amount to 2.3% of the country's electricity production. Under the leadership of Prime Minister Wen Jiabao, the Governing Council on March 22, 2006 deliberated the 'Medium and Long Term Development Plan for Nuclear Power 2005-2020'. Under the heading of 'Safety First and Quality First', the plan incorporates an ambitious program of development of advanced reactor concepts for the next 14 years. The development program is based on these premises: - Mainly pressurized water reactors will be used. - Fuel elements will be produced by industries in the country. - Maximum use is to be made of national capacities in designing and building the plants. - At the same time, international cooperation is to be promoted. In connection with its far-reaching plans about nuclear power, China is steadily pursuing the complete establishment of all technologies and facilities needed for supply, waste management, and operation as well as of research and development capacities.

  3. Design validation and BN-800 power unit construction status

    International Nuclear Information System (INIS)

    In 2006, the Government of the Russian Federation has approved the Federal target program 'Development of nuclear power generation complex in Russia up to 2015'. Along with accelerated construction of large VVER-1000 power units, the program envisages the development of nuclear power innovative technologies. They include the activities in fast neutron reactors, which are involved in the perspective to change nuclear power over to closed fuel cycle, which provides the most efficient use of uranium resources and solution of highly actual political and ecological issues of SNF and RW handling. The central stage of the innovation component of target program deals with construction of fast sodium reactor BN-800 that shall take the important stage in development of fast breeder reactor technology and in generation of closed fuel cycle of nuclear power industry. BN-800 design has been developed on the basis of BN-600 reactor, which operates successfully at Beloyarsk NPP starting from 1980. During this period, the reactor plant shows high and stable indices of reliability, safety and efficiency. Average annual plant capacity factor of power unit from the moment of reaching of design rate (from 1982) is 75.7%. In addition, unscheduled loss of plant capacity factor value due to process equipment failures is small (∼ 2%). The final technical decisions on BN-800 were made in 1990th after Chernobyl NPP accident and following strengthening of requirements for nuclear-power safety. For qualitative safety enhancement, BN-800 design implements some predominantly passive systems (additional emergency protection rods hydraulically suspended in sodium coolant, emergency cooling air HX, tray for confining of core melt under hypothetic accident). During design upgrading, the improvements aimed at enhancement of technical-economic indices were also introduced. The main fact that allows sufficient decrease (by 34%) of RP specific metal consumption is BN-800 power increase by ∼45% at

  4. 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)

  8. 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

  9. Status of X-band power source development for JLC

    International Nuclear Information System (INIS)

    The main X-band linac consists of klystrons, modulators, DLDS pulse compression/delivery systems, and RF accelerating structures. The periodic permanent magnet (PPM) klystrons are under development in the two-year/two-stage project with Toshiba. The goal is to produce 50 MW output power at 1.5 μs pulse length at the first klystron and then to advance to 75 MW at the second one. The first PPM klystron has been tested, and it achieved 56 MW power with 50% efficiency at 1.5 μs pulse length. The second PPM klystron is currently under testing, and the efficiency already reached 56% at the specified cathode voltage. As for the modulator, KEK is now developing a new IGBT (Insulated Gate Bipolar Transistor) modulator as a two-year project. Two prototypes, with three and ten stages of modules for 6 kV and for 20 kV output pulse each, were built and tested successfully. KEK is developing the multi-mode 2x2 DLDS (Delay Line Distribution System) power distribution system. For the study the stability of possible propagation modes and for the measurement of their transmission losses on a delay line, joint experiments with SLAC and BINP were performed at KEK on a 55 m long waveguide assembled in the ATF linac. The experiments showed the best combination of two modes to be TE01 and TE02 modes. The design of all RF components for the TE01/TE02 dual DLDS was completed and their cold models will be tested soon. Details of these developments and measurement results are presented. (author)

    International Nuclear Information System (INIS)

    As reported at the 1996 CNS Annual Conference, in mid-1995 the CANDU industry began to develop validation matrices for CANDU power plants. Of the eight matrices required to address all physical phenomena that could occur in all relevant accident categories, two have been prepared and tabled with the Atomic Energy Control Board, and the remaining six are targeted for submission during 1997. The matrices provide the generic, code-independent knowledge base that will be used to validate major safety analysis codes over the next four years. The unique achievement reported in this paper is the identification and listing of all physical phenomena in all relevant accident categories. (author)

  12. Worldwide Geothermal Power Plants: Status as of June 1980

    Energy Technology Data Exchange (ETDEWEB)

    DiPippo, Ronald

    1980-12-01

    There are 100 geothermal power units now in operation throughout 12 countries, with a total installed capacity of just over 2110 MW. The average unit thus is rated at 21.1 MW. Newer units may be broadly classified as follows: (a) wellhead units of less than 5 MW; (b) small plants of about 10 MW; (c) medium plants of 30-35 MW; (d) large plants of about 55 MW; and (e) complexes typically consisting of several 55 MW units in a large geothermal field. There is a trend toward turbine units of the double-flow type with a 55 MW rating, used either alone or in a tandem-compound arrangement giving 110 MW in a single power house. This is particularly evident at The Geysers field in California. Double-flash units (separated-steam followed by a surface flash) are suited to high quality reservoirs having high temperature, high steam fractions at the wellhead, and low scaling potential. Single-flash units (separated steam) may be called for where scaling by the spent brine is a potential problem for the liquid disposal system. Binary plants are being used for some very low temperature reservoirs, particularly in the People's Republic of China, albeit in extremely small units. A large-scale pilot plant of the binary type is being planned for the Imperial Valley of California.

    This paper summarizes the progress that has been made in the development of the Fission Power System Technology Demonstration Unit (TDU). The reactor simulator core and Annular Linear Induction Pump have been fabricated and assembled into a test loop at the NASA Marshall Space Flight Center. A 12 kWe Power Conversion Unit (PCU) is being developed consisting of two 6 kWe free-piston Stirling engines. The two 6 kWe engines have been fabricated by Sunpower Inc. and are currently being tested separately prior to integration into the PCU. The Facility Cooling System (FCS) used to reject convertor waste heat has been assembled and tested at the NASA Glenn Research Center (GRC). The structural elements, including a Buildup Assembly Platform (BAP) and Upper Truss Structure (UTS) have been fabricated, and will be used to test cold-end components in thermal vacuum prior to TDU testing. Once all components have been fully tested at the subsystem level, they will be assembled into an end-to-end system and tested in thermal vacuum at GRC.

  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.

  1. Seismic design of nuclear power plant components. Status and trends

    International Nuclear Information System (INIS)

    The report presents an overview about the present state of seismic design of plant components in Germany and in accordance with the German KTA 2201.4 rules, respectively. A discussion of the design objectives as part of the entire chain of nuclear power plant design is followed by an explanation of the systematic approach along the lines of KTA rule 2201.4, which is currently undergoing revision. The impacts on site or at the place of installation are determined, and special reference is made to possible methods of design and demonstration: computational and experimental approaches as well as analogy and plausibility procedures. The processes are explained and attention is drawn to inherent conservative factors. Knowledge of these factors in particular is of immense importance within the framework of a seismic PSA as part of a PSR. Reserves are apparent also from considering seismic design in the light of plant behaviour in real-life earthquakes. The report shows how revision of KTA 2201.4 re-establishes the connection to the international state of the art by opening the concept to more realistic procedures. (orig.)

  2. Technology status of tantalum alloys for space nuclear power applications

    International Nuclear Information System (INIS)

    Tantalum alloys have a variety of properties which make them attractive candidates for application in nuclear power systems required to operate in space at elevated temperatures (1200 to 16000K) for extended time periods. Most of the technology development on this class of alloys which is pertinent to space system application occurred during the 1960 to 1972 time period under NASA sponsorship. The most extensive data bases resulting from this earlier work were obtained on the alloys T-111 (Ta-8W-2Hf) and ASTAR 811C (Ta-8W-1Re-0.7Hf-0.025C). Emphasis in this paper is directed at the following technical factors: producibility, creep strength, weldability and compatibility. These factors are considered to be the most important elements in the selection of alloys for this application. Review of the available information indicates that alloys of this type are appropriate for application in many systems, particularly those utilizing alkali metals as the working fluid. 43 refs

    There are a number of theoretical frameworks which aim to provide a language for understanding and discussing the nature of power and influence in organisational decision making. One of the most recent and comprehensive frameworks is that developed by Mintzberg. Following a resumé of the most pertinent sections of Mintzberg's framework, this paper uses it to investigate the power relationships in an NHS Mental Health Unit (MHU) considering NHS Trust status. This investigation reveals some important conclusions about the nature of power in the NHS but also explores some of the limitations of the framework as a descriptive and predictive tool.

    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.

  13. 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.

    2012-10-15

    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.

  15. Development and future perspective of nuclear power plants. Current status and future prospect of world nuclear power plants

    International Nuclear Information System (INIS)

    Fukushima Daiichi NPS accidents occurred on 11 March 2011 brought about great effects on nuclear development not only in Japan but also in the world. In Japan restart of operation of periodically inspected nuclear power plants (NPPs) could not be allowed except Oi NPPs two units and most parties except Liberal Democratic Party (LDP) pledged to possibly phasing out nuclear power at House of Councillors election in July and public opinion was mostly against nuclear power after the accident. LDP clearly stated that, with the inauguration of new government last December, Japan would not pursuing the policy of the prior government of possibly phasing out nuclear power by the 2030s, but would instead make a 'zero-base' review of energy policy. Germany decided to close eight reactors immediately and remaining nine by the end of 2022. For many countries, nuclear power would play an important role in achieving energy security and sustainable development goals. In 2011 NPPs 6 units started operation with 2 units under construction, and in 2012 NPPs 3 units started operation with 7 units under construction. At present there are now over 400 NPPs operating in 31 countries and world trend seemed nuclear development was continued and number of countries newly deploying NPPs was increasing as much as eighteen. This article presented current status and future prospect of world NPPs in details. Japan would like to share its experiences and information obtained from the accident with the world and also promote NPPs overseas to meet the world's expectations. (T. Tanaka)

  16. Design status of the HTR 500 power plant and the HTR module power plant

    International Nuclear Information System (INIS)

    The HTR 500 nuclear power station is a dual-cycle plant with high-temperature reactor and steam power plant for electrical power generation, with the additional possibility of process steam and district heat extraction. The design of the HTR 500 makes considerable use of the technology embodied in the THTR 300. The simplifications and optimizations reflected in the HTR 500 design are based on practical experience with the THTR 300. Thus the transition to commercial high-temperature nuclear power plants means little risk for utilities and manufacturers. Its main features are: integrated design of the primary system components in a single-cavity concrete pressure vessel; use of standardized components and proven materials from the THTR 300 wherever possible; separation of operating and safety systems, leading to simple design; accident control making use of the slow transient characteristics of the high temperature reactor. Summing up, we can say that the HTR 500 and the HTR Module are good candidates for nuclear energy production and for chemical processes. The development of the HTR reactor allows to start the construction in the 90s. It is, therefore, a special challenge to convince the decision-makers to use the advantages which the high-temperature reactor system can offer. The research and development work has been sponsored by the BMFT, MWMT and the Swiss Government. Major contributions are made by KFA and the Paul Scherrer Institute

Data were collected from 165 male soccer coaches (n=71 technical director-manager and A license, n=46 B license, n=48 amateur license. An adapted Turkish version of Power in Soccer Questionnaire-Self (PSQ-S for coaches and an information form were used for the data collection [21]. Cronbach reliability alphas of PSQ-S range between 0.65 and 0.84. Coaches’ data were analysed by Kruskal-Wallis and Mann-Whitney tests. Kruskal-Wallis analysis of PSQ-S revealed significant differences between leadership power perception of amateur and professional soccer coaches according to their marital status related to Referent Power (RP [χ[sup]2[/sup] (3 = 9.61, p0.05. The results indicated that married coaches have higher perception of RP than single coaches, irrespective of being an amateur or a professional. Comparison of professional and amateur coaches suggests that while single professional coaches have higher perception of EP than married professional coaches, the results are the reverse for amateur coaches; in other words, amateur married coaches have higher perception of EP than amateur single coaches. There is a lack of research to draw more certain conclusions. Future researchers should also take into consideration personality, psychological skills, sport experience, age, taking responsibility, attributions, expectations, emotions, perception of achievement, etc.

  18. Review of the design status of the SP-100 Space Nuclear Power System

    International Nuclear Information System (INIS)

    The Heat Pipe Space Nuclear Reactor (HPSNR) System is one of the advanced designs for space nuclear power applications presently being considered. However, a number of design features will continue to require substantial technology and development before considering the system for deployment. This paper reviews the design status of the HPSNR system, as of October 1982, discusses the limitations of the current design and emphasizes those technical areas requiring additional research needed to support continual system development. The topics and design limitations discussed are common to most space nuclear power systems that are currently being developed under the SP-100 program to produce 100 kWe of continuous power in a space environment

  19. The status of nuclear power plants in the People's Republic of China

    International Nuclear Information System (INIS)

    China's main energy source is coal, but transportation and environmental problems make that fuel less than desirable. Therefore, the Chinese, as part of an effort toward alternative energy sources, are developing nuclear power plants. In addition to providing a cleaner power source, development of nuclear energy would improve the Chinese economic condition and give the nation greater world status. China's first plants, at Qinshan and Daya Bay, are still incomplete. However, China is working toward completion of those reactors and planning the training and operating procedures needed to operate them. At the same time, it is improving its nuclear fuel exports. As they develop the capability for generating nuclear power, the Chinese seem to be aware of the accompanying quality and safety considerations, which they have declared to be first priorities. 50 refs., 7 figs

  2. 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

  3. Status of an induction accelerator driven, high-power microwave generator at Livermore

    International Nuclear Information System (INIS)

    The authors are testing an enhanced version of the Choppertron, a high-power rf generator which shows great promise of achieving greater than 400 MW of output power at 11.4 GHz with stable phase and amplitude. This version of the Choppertron is driven by a 5-MeV, 1-kA induction accelerator beam. Modifications to the original Choppertron included aggressive suppression of high order modes in the two output structures, lengthening of the modulation section to match for higher beam energy, and improved efficiency. Final results of the original Choppertron experiment, status of the ongoing experiment and planned experiments for the next year are presented. The motivation of the research program at the LLNL Microwave Source Facility is to develop microwave sources which could be suitable drivers for a future TeV linear e+e- collider

  5. 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

  6. 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.

  7. 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

    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

  9. 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. All experimental and prototype high temperature reactor plants in Germany and USA had already been under decommissioning processes, with various safestore conditions depending on the specific project circumstances. The German AVR is being prepared for step-by-step dismantling the reactor structure. The Beloyarsk NPP based on ex-Soviet Union graphite reactor concept is still in preparatory phase in

  10. The current status of Chinese nuclear power industry and its future

    International Nuclear Information System (INIS)

    During the past 30 years, economy of China has being grown strongly. Even in the year 2009, when the world was hit by the financial crisis, China still kept the 8.7% growth rate. GDP of China has reached 4222G USD. This figure makes China to become the third economic giant in the world. All of the world are focusing on the high-speed development of economy in China; meanwhile they also pay much attention on the energy consumption in China. In addition, as one of the policy to keep the stable supply of the energy and to cut off the drain of CO2, China now are building more and more nuclear power stations. Many developed countries are very interested in the big market. Some have already joined in the construction of nuclear power stations in China, while some may concern about the supply of the nuclear fuel, as well as nuclear safety in China. The present paper will give a close-up view on China status of the energy, especially the nuclear power industry. It is expected that the international community could have deeper and more complete understanding on the nuclear industry in China, moreover cooperate with China to improve the peace and safe utilization of nuclear energy for the sustainable development of the world.

  11. 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

  13. Current status of steam dryer performance under power uprate in Boiling Water Reactors

    International Nuclear Information System (INIS)

    Highlights: • Steam dryer performance after extended power uprate is considered. • Effects of Acoustic Side Branches (ASB) on steam dryers is analyzed. • The ABS represents a reduction in the acoustic loads to the steam dryer. • Spectrograms of signals were obtained for frequency analysis. - Abstract: This work is a compilation of the current status of the steam dryer performance after the implementation of power uprates in Boiling Water Reactors (BWR). Some Nuclear Power Plants (NPPs) have reported failures and cracking in the steam dryer by acoustic resonances that cause excessive vibration due to the increase of steam flow. The replacement of the steam dryer, structural reinforcement and the connection of Acoustic Side Branches (ASB) are the main solutions adopted in order to avoid mechanical failures. The signal analysis of the vibration of the main steam lines in a typical BWR5, was performed using the Short-Time Fourier Transform (STFT). Signals were collected by the strain gauges located around the main steam lines (MSL). Two scenarios are analyzed; the first, is the signal obtained before the installation of the ASB, and the second, the signal obtained after installation. The results show the effectiveness of the ASB to damp the strong resonances when the steam flow increases, which represents an important reduction in the acoustic loads to the steam dryer

  14. 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

  15. 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

  17. Implementation of an automated status analysis system in an operating nuclear power plant

    International Nuclear Information System (INIS)

    A description is presented of a computer system designed to perform real-time, automatic analysis of the implications of arbitrary degraded states of a reactor's safety systems. In such states, one or more elements of one or more systems is inoperable, and the analysis problem is to determine the implications of this status with respect to reactor operations and the technical specifications stipulated by the regulatory authorities. The computer system is programmed to accomplish this analysis and to communicate the results to the reactor operator. The system has been designed for use by the reactor operating staff both for making real-time decisions when any of the reactor's systems are in an unanticipated state and also for planning maintenance and test activities. To verify the efficacy of the design concept an experimental version of the system (RGB-F) has been implemented at the Swedish Forsmark 1 nuclear power plant. (orig.)

  18. Present status of the waste management at Laguna Verde nuclear power plant

    International Nuclear Information System (INIS)

    Since July 1990, the Mexican Nuclear Power Station - Laguna Verde, unit I - is commercially in operation, unit II is under construction and is expected to start commercial operation in 1994.Both units have the necessary provisional installations for disposal of spent fuel and for law-level wastes. Special attention has been given to reach an integral waste management for the interim storage time as well as for long term storage, with emphasis on final disposal. This article summarizes the status of the waste management at Comision Federal de Eletricidad for disposal of spent fuel and high level wastes. In the first part the high-level waste, composed essentially by spent fuel and highly irradiated components (neutron detectors and control rods) is discussed. Comments about the low-level wastes, composed of dry actives (paper, gloves, clothing) and solid wastes (chemical concentrates, mud and resumes are in the second part.

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

    International Nuclear Information System (INIS)

    The present Canadian nuclear power program based on the CANDU-PHW reactor, future commitments, and the status of heavy water production, are discussed, together with short term prospects over the next 20 years. The longer term favours fuels with higher fissile content than natural uranium. Possible future strategies are discussed, which include consideration of a number of different fuel cycles for the different types of CANDU reactor, i.e. CANDU-PHW, CANDU-BLW, CANDU-PLW and CANDU-OCR. It is concluded that: CANDU-PHW reactor is fully reliable and competative; organic and boiling water cooled variations promise savings of 15 to 20% in both capital and unit energy costs; the CANDU concept offers the opportunity for large improvements in uranium conservation whilst remaining economically competitive, by use of plutonium recycle and/or thorium; using the CANDU concept with thorium it is possible to limit the total uranium requirement for a given nuclear power capacity; and finally a system based on CANDU-PHW reactors could introduce FBR reactors more quickly and efficiently than one based on LWR reactors.

    2000-12-01

    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.

    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.

The fourth section gives a thorough comparison and discussion of the two main fuel cell technologies used in FC-CHP (PEMFC and SOFC), characterising their technical performance and recent developments from the major manufacturers. The fifth section describes all the main components of FC-CHP systems and explains the issues connected with their practical application. The last part summarises the above, and reflects on micro FC-CHP system technology and its future prospects.

  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.

  9. Bruce and Darlington power pulse and pressure tube integrity programs -status 1995

    International Nuclear Information System (INIS)

    The optimum solution to pressure tube fretting at the inlet of the Bruce and Darlington channels, a concern which became very serious following inspections in early 1992, is to remove the inlet bundle and operate with a 12 fuel bundle channel. During analysis of this operating mode a 'power pulse' was identified which could occur during an inlet header break where all the fuel in the channel moved rapidly to the inlet of the channel. The pulse was unacceptable and the units were derated until solutions could be implemented. A number of solutions were identified and each station has begun implementation of their specific solution. Implementation has not been without problems and this paper provides a status report on the progress to date of the long bundle implementation solution for Bruce B and Darlington and the fuelling with the flow solution being implemented at Bruce A. Both types of solution have a significant impact on the original concern, fretting of the pressure tube. (author). 1 ref., 6 figs

  10. Current status of nuclear power plant I and C systems (2000)

    International Nuclear Information System (INIS)

    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

  11. Development of technical standard for inspection and review of Nuclear Power Plant's physical protection status

    International Nuclear Information System (INIS)

    All the nuclear power plants (NPP) should take a regular inspection on their physical protection status. The law for Physical Protection of Nuclear Material and Facility and Radiological Emergency Preparedness (LPPREP) which entered into force on Feb. 16, 2004 makes the NPP to take inspection every two years. The inspection has been carried out based on the order. The orders provide the guideline to prepare the security plan and contingency plan of the licensee. The items that should be included in the plan are well explained. Both review and inspection are conducted based on these items in a qualitative manner. However, the items designated in the orders are not so specific that more detailed standards including quantitative data are needed. In order to cope with increasing demand from both industries and competent authorities, KINAC (Korea Institute of Non-proliferation And Control) that has been performed review and inspection entrusted from the MOST has launched the program to develop more detailed technical standards in both quantitative and qualitative manner. This paper is written to introduce the activities of KINAC for developing the technical standards for review and inspection of the NPP. The results obtained from the study and future plan are explained

  12. The health status of Chernobyl nuclear power plant accident liquidators in Latvia

    International Nuclear Information System (INIS)

    The accident at the Chernobyl Nuclear Power Plant (NPP) in 1986 is so far the largest nuclear accident, and has created a new problem for nuclear medicine. This accident has also become a problem for Latvia due to the more than 6000 residents who participated in the clean-up works at Chernobyl. The aim of our study was to assess the health status of Chernobyl NPP accident liquidators, in comparison with a male control group in Latvia. We have examined the health of 2512 Chernobyl clean-up workers (males between age of 35-55 with documented and biologically estimated doses of received ionising radiation). For comparison of morbidity, we used a control group consisting of 3887 employees of the Ministry of Internal Affairs (males of the same age groups). The morbidity of Chernobyl NPP accident clean-up workers was generally higher than of control group. The highest contribution to morbidity in each age group of liquidators was from digestive, musculosceletal, nervous system and circulatory system diseases, as well as from mental disorders. (author)

  13. 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

    Sit-to-stand (STS) movements are essential for daily activities. Failure to perform STS movements efficiently and smoothly may lead to falls. In this study, we developed a forceplate to analyze vertical ground reaction force (VGRF), STS duration and generated muscle power to investigate which parameters were fall status predictors. A total of 105 participants were included in this study and were grouped into those (1) aged between 20 and 30 years (Young), (2) aged above 65 years without a history of falling (Non-fallers) and (3) aged above 65 with a history of falling in the past 12 months (Fallers). The results indicated a significantly higher maximal lower limb muscle power (MP) for the Young (9.05 ± 3.66 W/kg), followed by Non-fallers (5.50 ± 2.02W/kg) and Fallers (3.66 ± 1.45 W/kg) as well as higher modified falls efficacy scale (MFES) scores for the Young (Young: 9.88 ± 0.10; Non-fallers: 6.27 ± 1.40; Fallers: 4.83 ± 0.89) and shorter times for the five times sit-to-stand test (FSTST) for the young (Young: 6.09 ± 2.20 s; Non-fallers: 15.65 ± 3.30s; Fallers: 19.82 ± 4.46 s). There was a significant difference between the Young group and the Non-fallers in the maximal vertical ground reaction force (VGRF) (138.79 ± 24.20 N/BW in Young, 117.51 ± 8.57 N/BW in old Non-fallers, p < 0.01), and there was a significant difference between the Non-fallers and the Fallers in the duration of the STS movement (2.74 ± 0.87 s for the Non-fallers, 4.27 ± 2.56 s for the Fallers, p < 0.01). The regression analysis results further indicated that only MP and the STS stabilization phase could differentiate individuals who had past fall events. Therefore, the equipment we developed could potentially be useful in the assessment and monitoring of balance and the risk of falling in older people. PMID:24974126

    Work in the field of local power peaking performed during the past years comprises experimental and theoretical studies. Extensive theoretical work was performed by the Kurchatov Institute in Moscow, KFKI, and the Institute for Nuclear Research and Nuclear Energy in Sofia (in collaboration with the Kozloduy NPP). Computer codes used in this work included PERMAK3D, SPPSHB, KARATE-440, MCNP, BIPR-7 and PERMAK-A. The results of the calculations were compared either with observed values (Kurchatov Institute, PERMAK-3D) or with a reference solution (Bulgaria, SPPSHB). The BIPR-7 code was used by the Kurchatov Institute for a realistic full-core WWER-440 computation. Experimental work was performed by the Kurchatov Institute in 2000 and by the Nuclear Research Institute Rez (Czech Republic) in 1993 and 2001. Experimental work performed by the Nuclear Research Institute focused mainly on the radial power distribution, although some results of the axial power distribution were also available. The experiment performed by the Nuclear Research Institute in 2001 focused on the axial power distribution in the vicinity of the CA. The experimental results were compared to the MCNP calculation and a good agreement in the power distribution levels was generally observed. The experiments performed so far cover high boron concentrations in the presence or absence of hafnium inserts and zero boron concentration without hafnium inserts. The fuel pins selected for measurement were different in each experiment

  9. Improve the accuracy of the power distribution reconstruction using power distributions of different status as the fundamental harmonic

    International Nuclear Information System (INIS)

    Modular high temperature gas cooled reactor HTR-PM demonstration plant, designed by INET, Tsinghua University, is being built in Shidaowan, Shandong province, China. HTR-PM adopts pebble bed concept. Like other HTR, to measure or monitor the core power distribution is very important but challenging for HTR-PM, as there is no in-core neutron detectors. There are some proposals to reconstruct the power distribution from the readings of ex-core neutron detectors. One method is harmonic synthesis method. In this paper, improved harmonic synthesis method is proposed and tested to increase the accuracy of the power distribution reconstruction, by using better fundamental harmonic according to different reactor operation conditions. The numerical result shows the improvement in the reconstruction accuracy, contrasting to harmonics' coefficients polynomial expansion method. (author)

    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.

  18. Reports of status and prospects of fuel-power sector in Konin province

    International Nuclear Information System (INIS)

    In Konin province (Central Poland) 2 brown coal quarries ''Konin'' and ''Adamow'' as well as 3 thermal power plants ''Patnow'', ''Adamow'' and ''Konin'' are located. The brown coal reserves used for fuelling the local power plants should not be scooped before 2040. The power plants require modernization. ''Konin'' quarry has bought about 10000 hectares. Revegetation was already made on about 4000 hectares. The old dumps are covered with clays and therefore these areas have better soils as in the past. Due to fuel-power sector development the number of Konin town residents changed from about 12000 in 1950 to about 83000 in 1997

  19. Development and present status of new horizontal shift bump power supply for injection bump at the J-PARC RCS

    International Nuclear Information System (INIS)

    The new horizontal shift bump (SB) power supply for injection bump has been developed and manufactured according to the energy upgrade of the LINAC (Linear accelerator) in J-PARC (Japan Proton Accelerator Research Complex) 3-GeV RCS (Rapid-Cycling Synchrotron). The injection energy was increased from 181MeV to 400MeV, and the power capacity of the new power supply was doubled. The power supply adopted a capacitor commutation method to form the trapezoid waveform pattern (bump waveform) by the IGBT (Insulated Gate Bipolar Transistor) switch. The test operation was started in January, 2014. However, the diodes of the DC charger in the FT-unit (Flat top unit) were frequently damaged and then the user operation was started without using the FT-unit. As a result, the flat-top part of the bump waveform had a slight inclination. Both the horizontal paint bump magnets in the ring and the pulse steering magnets at the injection line were used to make up for the inclination and to correct the orbit errors at the injection point. This paper reports characteristic, the trouble and the user operation status about the new shift bump power supply. (author)

    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.

  5. 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

  6. 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.

    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 utilities and in states that have introduced competition into their retail electricity markets. Today, more than 50% of all U.S. consumers have an option to purchase some type of green power product from a retail electricity provider. This report provides an overview of green power marketing activity in the United States. The first section provides an overview of green power markets, consumer response, and recent industry trends. The second section provides brief descriptions of utility green pricing programs. The third section describes companies that actively market green power in competitive markets and those that market renewable energy certificates nationally or regionally. The final section provides information on a select number of large, nonresidential green power purchasers, including businesses, universities, and government agencies.

    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.)

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.

  15. Status of the horizontal paint bump power supply of the J-PARC RCS

    International Nuclear Information System (INIS)

    In 3-GeV RCS (Rapid-Cycling Synchrotron) of J-PARC (Japan Proton Accelerator Research Complex), the beam commissioning test with 400 MeV beam injection energy from LINAC (Linear Accelerator) was started in January, 2014, and the J-PARC user operation was started in February of the year. The performance of the paint bump power supply was upgraded, which is 1.6 times output current and 2 times output voltage. The new power supply operation was started without a trouble on schedule. However, after the test operation of the new shift bump (SB) power supply, the trouble of the circuit part was frequent. Therefore the excitation wave pattern of the horizontal paint bump (PBH) power supply, which was combined the function of the horizontal shift bump power supply pattern and the painting injection pattern, was demanded. In this paper, the contents of the upgraded power supply of the horizontal paint bump and the method of the any output wave pattern formation is reported. (author)

  16. Status of the Romanian nuclear power program and the strategy related to the public information

    International Nuclear Information System (INIS)

    The year 1997 represented for the Romanian nuclear power sector the year of the performances and capabilities proved Cernavoda NPP s unit operation, after one year of successful operation. Good performances of this unit could represent a positive impact on further development of nuclear power in Romania, considering first the completion of Unit 2 and for National Heavy Water Reactor Program. On the other hand, 'The years of 1997 and 1998 marked for the Romanian Electricity Authority a new and completely different perception of the Romanian power sector'. Recently, the first step of the restructuring of power sector has been accomplished. The Romanian Government approved the creation of the National Power Grid Company and the moving-out of the nuclear activities. The present Nuclear Power Group from RENEL was transformed in a separate entity, the National 'Nuclear Ellectrica' Company, including three subsidiaries, no legal persons, one for nuclear power production CNE-PROD (Cernavoda Unit 1), one for nuclear power development CNE-INVEST (Cernavoda Unit 2 to 5) and one for nuclear fuel fabrication FCN (Pitesti Nuclear Fuel Plant). The other Units from Nuclear Power Group, such as the Heavy Water Plant - ROMAG, Center of Technology and Engineering for Nuclear Projects - CTON and the Institute for Nuclear Research-Pitesti - ICN have been transformed in a state owned company for nuclear activities. To better understand the aspects related to the nuclear power in Romania and the necessity of the continuation and development of a public information strategy based on the new look of the nuclear power sector, please, allow me to present you a few things with regard the Romanian nuclear program. The main targets of Public Information Program Strategy considered when assessing the strategy related to the public information were: education and built-up of a credibility on the construction of a nuclear power plant in general, and of the Cernavoda NPP, in particular; and once

  17. The status quo and future of nuclear power in Germany and worldwide

    International Nuclear Information System (INIS)

    In the context of predicted energy demand growth, concerns regarding the security of fossil fuel supplies and the need to curb greenhouse gas emissions, a reappraisal of nuclear power has taken place on national, European and international levels. While the Geman government concedes nuclear power only a ''bridging function'' to a world where energy demand is fully covered by renewable energies, international institutions like the International Energy Agency (IEA), the International Atomic Energy Agency (IAEA) and the International Panel on Climate Change (IPCC) see nuclear power as a key element of any sustainable long-term energy strategy compatible with climate protection. They call for a multiplication of nuclear power generation by 2050. In agreement with the international organizations mentioned, nuclear power and renewable energies are seen by AREVA as complementary, not as alternatives and represent today AREVA's core businesses. Over the last two decades, construction of new nuclear power plants has been centering mainly on Asia while in Europe and North America the focus was on lifetime extension of existing plants. In Germany, the government has announced to revise the lifetime restrictions imposed by a former government in 2002. But an upswing in the new-build market can be observed also in Europe, and major new-build programs are being prepared in the US and the UK. Several countries in Europe and abroad are planning new plants, and a growing number of countries, in particular in the Middle and Far East, plan to embark on nuclear power. The IEA scenario consistent with limiting global warming by the year 2100 to 2 C is highly challenging for utilities and the vendor industry, but feasible provided there is a stable political and regulatory environment. Several global vendors offer state-of-the-art designs for generation III+ reactors. (orig.)

  18. Status of the safeguards system developed for the LMFBR prototype power plant SNR-300 (KKW Kalkar)

    International Nuclear Information System (INIS)

    In this report the features of the safeguards system developed for the LMFBR Prototype Power Plant SNR-300 (KKW Kalkar) are described. Due to the fact that LMFBR fuel assemblies are mostly handled in a sodium or inert gas environment, visual control and counting of the assemblies containing nuclear material, as routinely used in a LWR power plant, cannot be applied for LMFBRs. Consequently, for safeguarding the Kalkar Nuclear Power Station, an automatic and continuous monitoring of the fissile material inventory is the main objective of special instrumentation, the ''Inaccessible Inventory Instrumentation System'' (IIIS). For a qualitative distinction between the various types of assembly the detection of the emitted neutron and gamma radiation turned out to be most adequate. Based upon this conclusion and taking into account its tasks, the IIIS is composed of an activity measurement system, a position-sensing system and a micro-computer system (MCS). The high reliability, high fraud resistance and low maintenance requirements have had an important influence on the IIIS design. Access to IIIS data is protected by special hardware and software measures. To protect the system against the results of power failures the IIIS possesses an automatic restart facility and a battery-buffered power supply for the RAM-unit of the microprocessor system used for data acquisition and evaluation.

  19. Demolition of the Rheinsberg nuclear power station. Current status, special occurrences, experience

    International Nuclear Information System (INIS)

    The Rheinsberg nuclear power station (KKR), like the Greifswald nuclear power station (KGR), is part of Energiewerke Nord GmbH (EWN). Consequently, the demolition strategy, the licensing strategy, the waste management strategy, and project management of both demolition projects follow the principles valid at EWN. As KKR and KGR are located in different federal states, 2 nuclear supervisory authorities in the respective federal states are competent. One licensing procedure applying to both locations was out of the question. In addition to the administrative setup and the technical parameters, there are also differences and special features in the technical equipment of the 2 nuclear power plants and the conditions applying at the locations of KGR and KKR, which must be taken into account. The article refers to some key items of decommissioning the Rheinsberg nuclear power station in the period between 2002 and 2007. On the whole, demolition of the Rheinsberg nuclear power station has progressed well. By late 2007, approx. 76% of the equipment to be demolished has been dismantled. Demolition of the equipment of KKR is to be completed probably by 2012. Since the closure of the Morsleben repository for radioactive waste (ERAM) in September 1998, the solid radioactive waste arising has been disposed of in the Nord interim store (ZLN) near Lubmin.

  20. Development of Resonant Diplexers for high-power ECRH – Status, Applications, Plans

    Directory of Open Access Journals (Sweden)

    Kasparek W.

    2015-01-01

    Full Text Available The development of diplexers for ECRH has been pursued at a number of institutes because of their attractive variety of applications: Power combination, non-mechanical, electrically controlled switching (of combined beams between launchers with tens of kHz, and discrimination of low-power ECE signals from high-power ECRH is feasible. In a first part, this paper reports on plasma experiments with a ring resonator (Mk IIa at ASDEX Upgrade. Commissioning experiments on fast switching between two launchers for synchronous stabilization of neoclassical tearing modes, as well as in-line ECE measurements have been performed, and experimental issues and first results are discussed. A clear influence of the switching phase on the amplitude of the 3/2 NTM mode was measured, complete stabilization could, however, not be demonstrated yet mainly due to imperfect resonator control. Concepts for improved tracking of the diplexers to the gyrotron frequency are presented. In a second part, the design of diplexers with ring resonators matched to HE11 fields is briefly discussed; these devices can be connected to corrugated waveguides without any mode converters. A compact version (MQ IV is under investigation, which is compatible with the ITER ECRH system (170 GHz, 63.5 mm waveguide, vacuum tight casing, with the final goal of high-power tests at the 170 GHz gyrotron facility at JAEA in Naka, Japan. First low-power test results are presented.

    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)

    Scarpa, F; Facco, A

    The development of high power, unconditionally stable solid-state amplifiers for superconducting low-beta cavities, performed at Laboratori Nazionali di Legnaro in the framework of the EURISOL Design Study and in collaboration with Synchrotron Soleil [1], has led to the construction and testing of two newly designed 10 kW units that can be used both individually or coupled together to obtain a 20 kW source. This family of amplifiers, based on parallel assemblies of 300 W modules equipped with mosfets and individual circulators, gives the possibility of operating in any matching conditions and also, at a reduced power, in case of failure of one mosfet. Characteristics of amplifiers and high power combiner will be described, and their performance and test results will be reported.

  3. Current status and strategy of safety regulation of nuclear power plants in China [Keynote address

    International Nuclear Information System (INIS)

    The National Nuclear Safety Administration (NNSA) of China, which insists on the policy of 'safety first, quality first', regulates nuclear power plants by means of a licensing system according to international standards and experiences, and performs nuclear safety reviews and inspections strictly since its foundation 20 years ago. The nuclear safety regulation in China, starting from zero and developing gradually, has established its elementary system and has greatly contributed to ensure the safety of nuclear power plants. Nuclear power will be developed on a larger scale in the future in China, so there would be more challenges in the field of safety administration. NNSA will take positive measures to face the challenges in order to ensure nuclear safety

  4. 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.

  9. 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

    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.)

  13. Status of CEA reactor studies for a 200 kWe turboelectric Space Power System

    International Nuclear Information System (INIS)

    A reference design for a 200 kWe Space Nuclear Power System has been developed by the CNES and CEA Agencies of the French Government in order to assess within a first study phase running from mid 1984 to mid 1986, the key feasibility issues and the development cost of a Space Power System compatible with the version of the European launcher (ARIANE V), that will be available after 1995, and with adequate power range and lifetime performances for the missions considered at that time. The heat from a fast spectrum lithium cooled reactor is converted by a turboelectric system, selected for its technological readiness and for its advantage over thermionics and thermoelectricity, of minimizing the total mass of 100 to 300 kWe power systems, considering the available radiator area afforded by the specific ARIANE V geometrical features. A heat pipe radiator is preferred to an equivalent gas cooled system, for the increased reliability brought by the large number of independent cooling elements. The successive topics addressed in the paper, include a description of the system main components and steady state operating conditions, and the present views about the start up procedure and the reactor control

  14. Combined Heat and Power from Municipal Solid Waste: Current Status and Issues in South Korea

    Directory of Open Access Journals (Sweden)

    Changkook Ryu

    2012-12-01

    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.

  15. Status of CEA reactor studies for a 200 kWe turbo electric space power system

    International Nuclear Information System (INIS)

    The present European ARIANE space program will expand after 1995 in the development of the large ARIANE 5 launch vehicle. Considering, that the range of power needs (50 to 400 kWe) and operation times required for the space missions planned after the year 2000, are relevant to a nuclear power system, the French Centre National d'Etudes Spatiales (CNES) invited in 1983 the Commissariat a l'Energie Atomique (CEA) to undertake preliminary studies on space power systems. The purpose of the present two year phase (mid 1984-mid 1986) is to identify key technologies for a space generator within the power range of interest and to estimate the development cost of such a project to be examined for commitment in 1986. This work mainly consists in the feasibility and cost assessment of a reference 200 kWe turboelectric space generator, selected for the maturity and availability of the conversion system and for its attractive specific mass compared to thermionics and thermoelectricity, considering the available radiator area afforded by the specific ARIANE 5 geometrical features. The system is basically composed of a fast neutron spectrum lithium cooled reactor, of a Brayton conversion loop and of a heat pipe radiator

    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.

    1996-12-31

    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?

  19. 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.

  3. Status of subjects related to lifetime extension of nuclear power plants in Argentina

    International Nuclear Information System (INIS)

    The possibility of lifetime extension in nuclear power plants depends on maintenance, safety assessment, corrective actions and continuous improvement during plants life. Atucha I nuclear power plant has a backfitting program ongoing, all the coolant channels have been replaced, the Emergency Power Supply System has been modified, a Second Heat Sink is under construction, and all the tube guide control rods were replaced, as well as the In core Neutron Flux Sensors guide tubes. Moreover, several safety assessments have been made, among which a plant specific Probabilistic Safety Assessment, which includes fire risk analysis, addressing radioactive releases different from reactor core ones, and a PSA during shutdown. Last of all, an analysis of the introduction of slightly enriched fuel elements into the core, and a pressure vessel integrity analysis were made. With respect to the pressure vessel integrity analysis, the Responsible Organization is working with the purpose of reducing the uncertainties associated to thermohydraulic, neutronic and fractomechanics calculus, looking for higher safety margins that will allow them to ask the Regulatory Body for a life extension. At Embalse nuclear power plant there exists an In Service Inspection Program to examine and verify the state of components and/or systems, to enable the prediction of any eventual damage and determine the corresponding corrective actions to preserve safety functions. The Responsible Organization also created the Technical Committee of Channels Subprogram for CNE to co-ordinate the task related to the pressure tube inspection program. A set of (ultrasonic and eddy current) measurement techniques of the pertinent parameters, as well as the 'Spacer Location and Repositioning' program, has been applied in CNE since the late eighties. The Regulatory Body required the Responsible Organization the elaboration of a Level 1 probabilistic safety assessment, aiming at evaluating CNE safety level, in order to

  7. Status of maintenance in the US nuclear power industry 1985. Volume 1. Findings and conclusions

    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.

  9. The present status of nuclear power and prospects for fast reactors - the IAEA outlook

    International Nuclear Information System (INIS)

    Nuclear power continues to provide a significant amount of the world's electricity supply. Based on the experience gained from about 6000 reactor years of operation, improvements are continuing to be made in the design of nuclear power plants of all types including liquid metal cooled fast reactors. Five demonstration, prototypical or semi-commercial nuclear plants with liquid metal-cooled reactors (LMR) are in operation in the world. Although the commercial deployment of fast reactors has not been seen as urgent due to the availability of adequate low-cost uranium resources there is an awareness in many countries that breeder reactors will be needed in the early decades of the next century. Adequate energy supply for all countries of the world is vital. The exploitation of all non-polluting forms of energy, of which nuclear energy is the most abundant, must be planned now to meet the growing worldwide energy demand. (author)

Crystal Rive NPS has the trouble on the cracks in the reactor building. In another hand Fort Calhoun NPS got the River flooding condition on June, 2011 same year of Fukushima Accident. This year we visited to survey the situation of Fort Calhoun NPS. Nevertheless, 5 Nuclear Plants are under construction right now. Watts Bar NPS restarted the construction. Amazing new plants are Vogtle Unit 3 and 4 and DC Summer Unit 3 and 4 which are all AP1000 designed by Toshiba And Westing House. These new plants have 1117 Mw with the passive features to prevent the Severe Accident and the human error. We visited Vogtle NPS this Febrary. On 1 the other hand, 4. plants declared to discontinued the operation. One is Oyster Creek NPS which is suffering from the concrete cracks in the reactor building. And also this plant has only one plant in their job site and the Power rate is 654 MW which is rather small this day and the company decided not to continue the operation. The similar situation is Kewaunee NPS which has only one plant and 560MW PWR. The rlatest topics are San Onofre Unit 2 and 3 which started the operation in 1983 and 1984 respectively. Last year they got the trouble on the Steam Generators which was CE design. They ordered Mitsubishi for the total Replacement. The new Steam Generators made the severe vibration and the steam leaked from the pipings which caused a lot of troubles and the costs. They decided not to continue the plants. By the way, the popularity of the nuke in US is that the pro-nuke is 65% and the anti-nuke is 30 and. US is still healthy on the nuclear power plant operation. (author)

  13. Status and prospects of nuclear power from fusion and from fission

    International Nuclear Information System (INIS)

    Full text: The advantages of nuclear power from fusion are inexhaustible fuel resources, ecological attractiveness, inherent safety, significantly lower level of radioactive wastes, and absence of the materials which could be used for weapons. Since the 1950s the intensive work resulted in a unique scientific and technological database. In 1985 M. Gorbachev, F. Mitterand and R. Reagan suggested to create the first experimental fusion reactor on an international basis. In 1988 an international team comprising specialists of the USSR, USA, EC and Japan started activities on the design of a reactor, which was named ITER, with active support from the IAEA. An engineering design of the 500 MW reactor was completed in 2001. The negotiations concerning ITER construction have been started. Canada, Japan, France and Spain proposed options for site selection. Canada, China and the Republic of Korea have joined the countries that had pioneered the project. The ITER would have important socio-economical and political implications for the world community. The time for creating such a reactor is ripe. The nuclear power from fission is an advanced technology providing for 16% of electricity in the world. The IAEA project INPRO was started after the Russian Federation President Vladimir V. Putin stated his Initiative at the UN General Assembly in 2000. This project addresses the strategic issues of development of future nuclear energy for the world from nuclear fission. INPRO has made a conclusion that Nuclear Fuel Cycle (NFC) is a system-creating factor. Prospects of such power depend on the solution of NFC back-end problem. It is necessary to begin the formation of NFC international structures, as a major component of the world fission power system. The establishment of an international research centre on spent fuel treatment technology and on radioactive waste storage is a practical step in this direction. (author)

    Energy Technology Data Exchange (ETDEWEB)

    Alimov, Yu.N.; Sushko, V.A.

    1985-08-01

    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.

    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.

  1. 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.

  2. Current status and analysis of renewable promotional policies in Indian restructured power sector - A review

    International Nuclear Information System (INIS)

    Restructuring has changed the traditional mission and mandates of power utilities in complex ways, and had large impacts on environmental, social, and political conditions for any particular country. At the same time, new regulatory approaches are being found for reducing environmental impacts in restructured power sectors. India has a vast supply of renewable energy resources, and it has one of the largest programs in the world for deploying renewable energy based products and systems. So this paper attempts to review the various policies and measures undertaken by Indian government for promotion of renewable energy. The aim of this paper is also to review the current policy mechanisms, especially investment- or generation-based price-driven and capacity-driven mechanisms, ranging from investment incentives for the development of renewable energy projects, feed-in tariffs, production tax incentives, tradable green certificates, and their effects upon the prospects of encouraging as well as expanding the development of renewable energy in Indian restructured power sector. This will make renewable more attractive in the Indian future electricity market. (author)

    Increasing emissions of nitrogen oxides (NOx) over the Chinese mainland have been of great concern due to their adverse impacts on regional air quality and public health. To explore and obtain the temporal and spatial characteristics of NOx emissions from thermal power plants in China, a unit-based method is developed. The method assesses NOx emissions based on detailed information on unit capacity, boiler and burner patterns, feed fuel types, emission control technologies, and geographical locations. The national total NOx emissions in 2010 are estimated at 7801.6 kt, of which 5495.8 kt is released from coal-fired power plant units of considerable size between 300 and 1000 MW. The top provincial emitter is Shandong where plants are densely concentrated. The average NOx-intensity is estimated at 2.28 g/kWh, markedly higher than that of developed countries, mainly owing to the inadequate application of high-efficiency denitrification devices such as selective catalytic reduction (SCR). Future NOx emissions are predicted by applying scenario analysis, indicating that a reduction of about 40% by the year 2020 can be achieved compared with emissions in 2010. These results suggest that NOx emissions from Chinese thermal power plants could be substantially mitigated within 10 years if reasonable control measures were implemented effectively. PMID:24010996

  5. What is the nuclear fusion power generation using laser? What is the current status of this technology?

    International Nuclear Information System (INIS)

    This paper reports the principle of laser fusion, the current status of nuclear fusion development in the world, and the world's first repeated nuclear fusion development project that the authors aim at. In February this year, at National Ignition Facilities (NIF) operated by US Lawrence Livermore National Laboratory, fuel gain reportedly exceeded the figure of 1 in the inertia confinement nuclear fusion, and self-heating by means of α particles have been demonstrated this time. In the nuclear fusion development project of the authors, the possibility that semiconductor kilojoule laser would become a reality in a few years has come out. As the midpoint of the roadmap, the authors are planning the construction of 'mini experimental reactor CANDY' that includes necessary elements for power generation reactor as much as possible, such as reactor core, feeding of the target, recovery of generated heat, and recovery of tritium.

  8. 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.

  16. 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.

  19. Present status of micro and mini-hydel power plants and biogas plants in Pakistan

    International Nuclear Information System (INIS)

    The Government of Pakistan has high priority to develop indigenous energy resources and announced a policy framework and package of incentives to private sector in hydro electric power generation. Hydro electric power in Pakistan has been estimated to be nearly 35,000 MW, whereas only 3330 MW have so far been exploited which constitutes only 15.11% share of the total commercial energy fuel consumption in 1994-95 and 42.7% of total electricity generation. The Government Agency in Pakistan i.e. WAPDA which produced 85.4% electricity generation had found it difficult to implement and run small hydro projects. There are 200 MHP plants were installed with a total capacity of 3,000 KW (3 MW), out of which 160 plants are working with 80% success rate. The selling price is Rs. 3.00 against cost of production is Rs. 0.11 per unit. Biogas is a clean and cheap fuel in the form of gas. The total dung available per day in the rural areas of Pakistan works out between 250-300 million Kg and 1804 million cubic m. of biogas can be produced having economic value of 6.711 billions. During 70's several biogas plants were installed but they have some problems. As regards biogas the production has remained stagnant for the last 5 years or more. There is need for clear governmental priorities and effective use of form biogas. (A.B.)

  20. 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

  1. 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)

  2. Operational status of the AGS Booster Main Ring Magnet Power Supply

    International Nuclear Information System (INIS)

    The Booster is a multipurpose accelerator interposed between a 200 MeV linac, a pair of 15 MV Tandem Van deGraaf accelerators, and the AGS. It can operate on slow cycles of 0.3 Hertz pulse repetition frequency up to a maximum of 7.5 Hertz. The different cycles, from long front porches for long injection or accumulation periods or flattops for slow extraction, to normal fast extraction cycles, accommodate protons, heavy ions (h.i.) and polarized protons. One of the systems enabling the flexible Booster operation is the Main Ring Magnet Power Supply (MRPS) system. It consist of a series connection of six, 1000 volt, multiphase rectifiers together with by pass switches. Two of the six operate at currents up to 6 kA and the rest up to 3 kA. All bypass switches are rated for 6 kA. The system is equipped with passive, damped LCRC filters as well as an active transformer coupled correction system. The MRPS is connected directly to the Long Island 69 Kv bus via a dedicated 20 MVA transformer. The choice of a series of modules enables the very flexible cycle generation and at the same time minimizes the deleterious effects of power factor and harmonics on the ac lines

  3. The current status and future prospects of the Korean nuclear power industry

    International Nuclear Information System (INIS)

    Recently, countries all over the world are becoming aware of the values and importance of nuclear energy which can help respond to energy crises caused by a sharp rise in oil prices and protect the earth from global warming. Since 1978, when Kori Unit 1(587MW), opened the nuclear generation era as a semi-domestic energy resource in Korea which is absolutely in short supply of energy, nuclear power generation in Korea has developed continuously for the past 28 years. Four new units including the Yonggwang 5 and 6 and Ulchin 5 and 6 have been successfully completed, raising the total nuclear installed capacity to 17,716MW from 20 units. At present, the nuclear generation in Korea is stably supplying about 40% of total electric generation, which is the fundamental energy of the nation, supporting the dynamic economic growth of Korea. In particular, Korean nuclear industry has been achieving excellent performance in nuclear power plant operation. The average capacity factor in 2005 hit the record of 95.5%, surpassing the previous record of 94.2% in 2003 in two years. Kori Unit 4 and another four units were listed at the top five in the capacity factor rating list of 2005 released by Nucleonics Week. In 2005, the site for radioactive waste disposal, which had been a long-cherished hope and the largest pending issue of the nuclear industry, was successfully selected in Korea through resident ballot as the first case of a national policy project, and as such, a national agenda was solved after 19 long years. Such a method in site selection has a significant meaning and establishes an excellent precedence; a large national policy project was decided upon by the residents themselves. As one of the model countries of building and operating nuclear power plants and technological independence, Korea is willing to contribute to the common goals of the world nuclear circle which can be summarized into energy security and environment preservation, by sharing accumulated

Within HiLASE we explore two major concepts: thin-disk and cryogenically cooled multislab amplifiers capable of delivering average output powers above 1 kW level in picosecond-to-nanosecond pulsed regime. In particular, we have started a programme of technology development to demonstrate the scalability of multislab concept up to the kJ level at repetition rate of 1-10 Hz.

  5. 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.

  6. A status report on the development of a high power UV and IR FEL at CEBAF

    International Nuclear Information System (INIS)

    Previously the authors presented a design for a kilowatt demonstration industrial UVFEL. Progress has been made in resolving several design issues identified in that work. More exact simulations of the injector have resulted in a better estimate of the injector performance. A more compact lattice has been designed meeting the design requirements for the UV FEL, and a new design point has been studied which greatly increases the threshold for longitudinal instabilities. A stability analysis of the RF control system has found that only minor modifications from the existing CEBAF controls will be necessary to allow them to be used with a high current, energy-recovery accelerator. Designs for the optical cavity length and figure control systems have been conceptualized and a model of the corner-cube resonator is being built and tested. Finally, three-dimensional simulations of the FEL have been carried out which show that the laser should exceed its minimum design goals for average power

  11. 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

  12. Status of seismic design requirements for nuclear power plants in Japan

    International Nuclear Information System (INIS)

    The paper describes the classification criteria, parameters and testing of aseismic designs for nuclear power plants. All buildings, structures, systems and components are classified according to their degree of importance for plant safety, and are designed to meet the requirements specified for each class. The magnitude and epicentre of the design basis earthquake are determined based upon seismological and geological investigations and observation of ground motion at the site, and the maximum ground acceleration that could be expected can be calculated empirically. More than three time history waves are selected referring to the dynamic characteristics of the base rock of the site, observed ground motion records at the site or other strong motion seismographs. The buildings and structures are treated as an elastic column system with masses, and the bottom mass is supported by elastic springs representing the soil-foundation interaction characteristics. The Design Earthquake Ground Motion is used as the input disturbance in the dynamic response analysis, and the modal analysis or time history method is worked out. The systems and components are modelled as elastic bars with lumped masses with a 3-dimensional degree of freedom, and the response analysis is carried out using floor response spectra. Real vibration tests have been carried out on some important items. Seismic trip devices with redundancy for the scram shut down of the reactor should some intense earthquake occur are connected with the safety protection system. (author)

  13. Status of High Power Tests of Normal Conducting Single-Cell Standing Wave Structures

    International Nuclear Information System (INIS)

    Our experiments are directed toward the understanding of the physics of rf breakdown in systems that can be used to accelerate electron beams at ∼11.4 GHz. The structure geometries have apertures, stored energy per cell, and rf pulse duration close to that of the NLC or CLIC. The breakdown rate is the main parameter that we use to compare rf breakdown behavior for different structures at a given set of rf pulse parameters (pulse shape and peak power) at 60 Hz repetition rate. In our experiments, the typical range of the breakdown rate is from one per few hours to ∼100 per hour. To date we have tested 29 structures. We consistently found that after the initial conditioning, the behavior of the breakdown rate is reproducible for structures of the same geometry and material, and the breakdown rate dependence on peak magnetic fields is stronger than on peak surface electric fields for structures of different geometries. Below we report the main results from tests of seven structures made from hard copper, soft copper alloys and hard-copper alloys. Additional details on these and other structures will be discussed in future publications.

  14. BWR manual control and status monitoring system for nuclear power plant

    International Nuclear Information System (INIS)

    As the unit capacity of nuclear power plants increases, the reduction of cost for construction and the improvement of operation availability have been strongly desired. The control and monitoring system with all solid-state equipments, in which the number of cables is greatly reduced by employing series transmission system as signal transmission, has been developed. The new system consists of the control rod drive control system and the control rod monitoring system. The former is composed of the control rod selector module, the control rod drive control panel, distributor module and the transponder. The latter comprises the position sensing probe, the control rod position information panel, whole core display, four control rods display and display memory module. The system operates in 3 modes of time-sharing control, scan, and automatic test. Compared with conventional systems, the new system is improved in three points. (1) The number of cables has been reduced to about 45% of that of conventional system, (2) system availability has been improved by adopting duplex circuits and on-line automatic test function, and (3) dimensions of the control panel has been reduced to about 35% of that of conventional system. In the control rod drive control system, failure diagnosing system is provided, which indicates the diagnosed results or failure positions on a plasma display by utilizing a micro-computer, and almost eliminates the necessity of searching failure positions in the complicated interior of equipments.

  15. Management of spent fuel from power and research reactors: International status and trends

    International Nuclear Information System (INIS)

    Spent fuel management has always been one of the most important stages in the nuclear fuel cycle, and stands among the most vital problems common to all countries with nuclear reactors. It begins with the discharge of spent fuel from a power or a research reactor and ends with its ultimate disposition, either by direct disposal or by reprocessing. Two options exist at present - an open, once-through cycle with direct disposal of the spent fuel and a closed cycle with reprocessing of the spent fuel and recycling of plutonium and uranium in new mixed oxide fuels. The selection of a spent fuel strategy is a complex procedure in which many factors have to be weighed. They include political, economical, and safeguards issues as well as protection of the environment. Because of the current low uranium prices, recycled uranium and plutonium cost more than newly mined uranium. Delays in the implementation of the fuel reprocessing option in some countries, the complete abandonment of this option in other countries, and delays in the availability of final spent fuel disposal in almost all counties have led to increasingly long periods of interim spent fuel storage

  16. Present status of expert system development at Power Reactor and Nuclear Fuel Development Corporation

    International Nuclear Information System (INIS)

    The use of an expert system is expected to permit labor saving, decreased exposure, reduced costs and improved safety. The Power Reactor and Nuclear Fuel Development Corporation has developed and introduced expert systems in various areas of nuclear fuel cycle technical development. The present report outlines four of these systems: the uranium resources exploration expert system, plutonium conversion facilities operation support expert system, experimental fast reactor 'Joyo' operation support system and experimental fast reactor 'Joyo' maintenance support system. Geological information on uranium deposit is incorporated in the uranium resources exploration expert system, which consists of a knowledge base, inference mechanism and knowledge acquisition editor. The plutonium conversion facilities operation support expert system can perform such functions as acquisition and processing of knowledge; abnormality diagnosis and operation guidance; and processing of abnormality diagnosis results. The system detects an accident, diagnoses the abnormalities, infers the cause of the abnormalities, finds the required countermeasures, and displays the conditions, cause of the abnormalities and countermeasures. The 'Joyo' operation support system is used for displaying countermeasures against an accident, sequence minitoring, prediction of plant conditions, etc. The 'Joyo' maintenance support system has the functions of abnormality detection, inference of the cause of abnormality, and print-out of required countermeasures, influence of the accident, etc. (Nogami, K.)

    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

  20. Status and issues on storage and disposal of radioactive waste from non-power applications

    International Nuclear Information System (INIS)

    Full text: The first part of the paper will outline and interpret the main legal provisions in the EU applying to the management of radioactive waste from non-power station applications including waste containing natural radioactivity from oil and gas production. It will include issues relating to transport, storage and disposal of the waste. Important Directives include: Council Directive 96/29/Euratom - which lays down basic safety standards for the health protection of the general public and workers against the dangers of ionising radiation; Council Directive 92/3/Euratom - which addresses the supervision and control of radioactive waste between Member States and of shipments into and out of the community; Council Directive 97/1 I/EC - which requires an environmental impact assessment to be undertaken for facilities for disposal or long-term storage of radioactive waste. The second part of the paper will discuss management schemes for non-power station waste in key EU member states, particularly the UK, Germany and the Netherlands, including a review of the facilities for waste storage and disposal. There is a wide diversity of approaches between different member states, reflecting different rules applying to the fate of waste materials. For example, in the Netherlands, waste for which the total activity concentration is less than 100 Bq/g dry weight can be unconditionally released, whereas, if the activity exceeds that level, it must be transferred to an authorised facility for treatment and storage. In Germany, material from oil and gas exploration with activity concentrations in the range 0.5 to 500 Bq/g has to be backfilled into abandoned wells. Wastes with activity concentrations of greater than 500Bq/g have to be treated and stored. Different rules also apply to the disposal of liquid waste. There are centralised facilities for treatment and long-term storage of waste, including disused sources, in Austria, Belgium, Denmark, Finland, France, Italy, the

  1. India's nuclear power programme present status, future prospects and related issues

    International Nuclear Information System (INIS)

    India is poorly placed in terms of world energy resources, while 16% of world's population lives in India, only 6% of coal and 0.6% of oil and gas reserves exist in the country. Moreover, the distribution of primary commercial energy resources is quite skewed. However, India is endowed with vast reserves of thorium. The energy potential of our modest uranium resources and sizeable thorium resources has been estimated to be six times that of our total coal reserves. Though during last fifty years since independence, India has made tremendous progress in the energy sector where the use of commercial energy has increased by ten folds. Electricity used during the same period has increased by eighty times. In spite of such an impressive growth the country, due to population growth, finds itself in the almost lowest bracket with regard to per capita consumption which is many fold lower than the world average. India as of today is a net energy importing country. The demand for energy, in particular electricity that has established to be the most efficient and convenient source, is projected to grow at 7-8% per annum for coming two decades. In such a demand scenario it is imperative that all the resources of energy must be judiciously utilised. However, with the depletion of fossil fuels and resulting possible price shocks a long-term energy security is required for the country. The paper deals with the role nuclear power can play in meeting the country's short term and long term demands, progress made and related issues. (author)

  2. Environmental radiation status in Bunkyo-ku, Tokyo, after the TEPCO Fukushima Dai-ichi Nuclear Power Plant disaster

    International Nuclear Information System (INIS)

    Bunkyo-ku is located in the eastern part of the metropolitan area of Tokyo, Japan, and is roughly 220 km south of the TEPCO Fukushima Dai-ichi Nuclear Power Plant. The population of the city was 201,079 as of August 1, 2012, and its area is 11.31 km2. The local government has officially been surveying the environmental radiation status after the disaster in response to numerous requests from its citizens. The radiation surveillance in this area has been technically guided by radiation protection specialists. The two main targets for surveillance are (1) the ambient radiation dose (microsieverts per hour) at all the school yards, public parks, and representative measurement points selected by the local government, and (2) the specific radioactivity (becquerels per kilogram) present in school lunch. These data have been reported to the citizens through the city website as well as in a bi-monthly report in the public relations magazine of the local government. This report presents the background status and technical information of the related activities, as well as the measured environmental radiation data. The ambient radiation dose in the city has been surveyed since July 2011. In the 1st period of surveillance (from July to August, 2012), over a total of 304 measurement points, the highest recorded value of the ambient radiation dose was 0.22 μSv h-1 at the height of 1 m from the ground, the lowest was 0.05 μSv h-1, and the average was around 0.09 μSv h-1. These values include the natural background dose rate detected by the energy compensation type surveymeters. In the most recent surveillance records, the maximum value recorded was 0.10, the minimum was 0.05, and 0.07 μSv h-1 was the average value. The specific radioactivity of drinking water has been monitored at local purification plants since the accident occurred. No water sample supplied to the city has exceeded the national limits for intake dose. The specific radioactivity of school lunch was also

  3. 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.

  10. 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

  11. 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

  12. 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)

    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. It...

    The ability of personality traits to predict important life outcomes has traditionally been questioned because of the putative small effects of personality. In this article, we compare the predictive validity of personality traits with that of socioeconomic status (SES) and cognitive ability to test the relative contribution of personality traits to predictions of three critical outcomes: mortality, divorce, and occupational attainment. Only evidence from prospective longitudinal studies was ...

    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.

    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.

    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.

    2004-01-01

    We have produced 400 ns rf pulses of greater than 500 MW at 11.424 GHz with an rf system designed to demonstrate technology capable of powering a TeV scale electron-positron linear collider. Power is produced by four 50 MW X-band klystrons run off a common 400 kV solid-state modulator. We present the layout of our system, which includes a dual-moded transmission waveguide system and a dual-moded resonant-line (SLED-II) pulse compression system. Dual-moding of the transmission lines allows power to be directed through a pulse compression path or a bypass path; dual-moding in the pulse compressor allows the delay lines to be about half as long as they otherwise would need to be. We describe the design and performance of various components, including hybrids, directional couplers, power dividers, tapers, mode converters, and loads. These components are mostly overmoded to allow for greater power handling. We also present data on the processing and operation of this system. The power from that system is transport...

  20. Characterization of the Water Quality Status on a Stretch of River Lérez around a Small Hydroelectric Power Station

    2012-10-01

    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.

  1. Large-area self-powered neutron-detectors for neutron-flux measurements in HTRs. Status of developmental work

    International Nuclear Information System (INIS)

    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

  2. Outlook on energy and electricity demand growth in developing countries, and status and perspectives for nuclear power

    International Nuclear Information System (INIS)

    The demand for energy in developing countries has been increasing at 5.7% annually in average since 1986, in comparison with the world average growth rate of 3.3%. Electricity is a preferred and use energy form for both developing and industrialized countries. Increasing demand of electricity is thus the logical future development, and it is clear that it will assume growing importance in the future especially in developing countries. Based on the long-term prospects of world energy and environmental evolution, nuclear power will remain an important element both in the world energy supply mix and in global environmental protection. Concerning financing, considerations should be given to the principal characteristics specific to nuclear power projects and how these complexities affect nuclear power financing. 5 refs, 3 figs, 9 tabs

  3. Status and development of instrumented fuel rod testing simulating the power reactor operating conditions in the research reactor MIR

    International Nuclear Information System (INIS)

    The paper includes the analysis of parameters for instrumented refabricated fuel rods having high burnup under power cycling as an example. The SSC RF RIAR carries out all activities, which are required for testing. The whole cycle of such activities, with the experiment with irradiated fuel rods of WWER fuel assembly has been carried out in the MIR reactor, is shown. The zero power reactor MIR (critical assembly) is used for experimental support and safety analysis. The main characteristics of the loop facilities, which are used for testing and the designs of several devices are presented. The location of fuel rods and sensors throughout the height and over the cross-section of the experimental device is shown. The changes of fuel rod (A) length and diameter as a function of average linear power throughout the fuel rod height and the relation between the length and diameter changes are given. The experiments with WWER-440 and WWER-1000 refabricated fuel rods having a burnup of 50 to 60 MWd/kgU approximately were carried out under repetitive power cycling conditions. The curves of linear power change in these experiments are represented schematically. Some results of the data processing, which are logged under the transient conditions during the first experiment with WWER instrumented refabricated fuel rods having a burnup of 50 MWd/kgU approximately are given. The change of the logged data on fuel temperature and neutron flux and changes in the length of fuel rods in the course of power change after different number of cycles are demonstrated. The experimental capabilities improvements like: 1) Development of the technique and experimental device for testing of WWER fuel rods under conditions simulating some design-basis accidents accompanied with pulse power change; 2) Improvement of dynamic techniques used for analysis of thermal and physical parameters of the WWER fuel rods, calculation of local power and heat-transfer factor with the help of correlation and

    International Nuclear Information System (INIS)

    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.

  5. Role of state supervision in quality assurance for nuclear power in the USSR (status and development prospects)

    International Nuclear Information System (INIS)

    The present activities in the field of surveillance include particularly inspection and prophylactic work which includes the following: issuance of licences permitting activities associated with the construction of nuclear power plants, revision of safety standards, inspection of nuclear power plant components supplied by the manufacturers, recording and licensing equipment and tube systems important from the safety aspects such as facilities for refuelling and for reactor unit start-up, and personnel training and education. Many institutes and organizations of various ministries and companies are currently engaged in the quality assurance of nuclear power plants while their responsibilities have not been clearly defined. Thus it appears necessary to create and implement a quality assurance programme for all stages of the nuclear power plant lifetime. A standards-type document of this kind has been prepared and should be implemented; this document respects IAEA recommendations as defined in documents Nos. 50-G-QA and 50-SG-QA1-QA11 and is not inconsistent with the ISO 9001 to 9004 standards.

    Xiong, Tianqi; Jiang, Wei; Gao, Weidong

    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.

  9. Evaluation of the reports on the status of quality assurance systems in the power plants. Pt. 1, annex, pt. 2

    International Nuclear Information System (INIS)

    The problem required the development of a presentation and evaluation of the overall results based on the results of the systems analysis with regard to: - further development of control equipment, - discovery of overlapping points, gaps and weak points, especially at the boundaries between the systems, - standardized application of the principles of efficient quality assurance systems for all participants. The results of the systems analyses for the status of quality assurance in producers and suppliers of systems can be summarized as follows: 1. Both systems analyses show that the quality assurance systems introduced are operable but that there are also some weak points. 2. Basically, the results of the systems analyses coincide; there are differences in the assessment of single issues or in a more detailed treatment. The weak points identified by the systems analysis can be summarized under the following catchwords: - structural organization; here, a greater formalization of the descriptions of positions and qualifications of personnel as well as the presentation of the structural organization in organization charts are required. - Procedural organization resp. operational modulei; here, improvements of the interfaces between the QA systems, information feedback, information and documentation are dealt with and the revision and improvement of invalid documents (withdrawal/exchange) as well as the qualification mode for auditors are pointed out separately.

  10. 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.

    Briggs, Maxwell H.; Geng, Steven M.; Robbie, Malcolm G.

    2010-01-01

    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.

  12. 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

  14. 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

  15. 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.)

  16. Data base on operator support systems (OSSDB) in nuclear power plants: Status evaluation. Technical report. Working material

    International Nuclear Information System (INIS)

    In 1991 the IAEA Committee for Contractual Scientific Services approved the Co-ordinated Research Programme on Operator Support Systems in Nuclear Power Plants in the framework of the Project ''Man-Machine Interface Studies''. The major goal of the co-ordinated research programmes was to supply guidance and technology transfer in the development and implementation of computerized support systems. Several sub-gals were identified to accomplish the first steps necessary to achieve this overall goal. Among others, creation of a databased containing the most pertinent characteristics of the OSSs operating in NPPs was recommended. The database is assumed to be of use to several groups of organizations. It therefore contains a large set of data on each specific OSS record. In this report an attempt was made to analyse the available data from the point of view of different user groups in order to guide the use as directly as possible into a practical use of the database. It is assumed that the reader on beforehand has made himself familiar with the main features of the database by reading the Users Guide, which is included in the Appendix 2 of the report. Figs, tabs

  6. Safety system status monitoring

    International Nuclear Information System (INIS)

    The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide

    Full Text Available The study performs an empirical survey to measure the impact of stress among people with various gender and marital status in a hydropower unit located in city of Esfahan, Iran. The study performs the survey among all 81 people who were working for customer service section of this company and consists of two parts, in the first part; we gather all private information such as age, gender, education, job experience, etc. through seven important questions. In the second part of the survey, there were 66 questions, which included all the relevant factors impacting employees' stress. We implement two Levin and t-student tests to see whether gender or marital status has any meaningful influences on creating stress among people. The results indicate that gender has no meaningful impact on creating stress among employees who worked for this hydro plant except difficulty of job conditions. The other findings of this paper is that stress posed from management team had different impacts on employees with various marital status but there were no meaningful differences between married and single couples in terms of other factors posing stress such as unsuitable working conditions, fear of job stability or difficulty of job conditions.

    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.

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.

    Although the majority of seizures are brief and cause no long-term consequences, a subset is sufficiently prolonged that long-term consequences can result. These very prolonged seizures are termed "status epilepticus" (SE) and are considered a neurological emergency. The clinical presentation of SE can be diverse. SE can occur at any age but most commonly occurs in the very young and the very old. There are numerous studies on SE in animals in which the pathophysiology, medication responses, and pathology can be rigorously studied in a controlled fashion. Human data are consistent with the animal data. In particular, febrile status epilepticus (FSE), a form of SE common in young children, is associated with injury to the hippocampus and subsequent temporal lobe epilepsy (TLE) in both animals and humans.

  7. Applicable technology. Chapter 3. Status report on the safety of operating US nuclear power plants (why experts believe that today's operating nuclear power reactors are much safer than they were 20 years ago)

    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.

    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

    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)

    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

  2. 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 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

Korea has one of the world's most vigorous nuclear power programs. Korea has been an active promoter of nuclear power generation since 1978, when the country introduced nuclear power as a source of electricity. Korea now takes pride in the outstanding performance of its nuclear power plants, and has established a grand nuclear power scheme. This paper is aimed at introducing the nuclear power program of Korea, including technological development, international cooperation, and CANDU status in Korea. (author). 2 tabs

  13. LIL laser performance status

    International Nuclear Information System (INIS)

    The Laser Integration Line (LIL) was first designed as a prototype to validate the concepts and the laser architecture of the Laser MegaJoule (LMJ). The LIL facility is a 4-beam laser representing a quad structure of the LMJ. A set of test campaigns were conducted to safely ramp up laser performance. The main goal was to measure quad-specific features such as beam synchronization and focal spot (size, smoothing contrast ratio or irradiation nonuniformity) versus the LMJ requirements. Following the laser commissioning, the LIL has become a major instrument dedicated to the achievement of plasma physics experiments for the French Simulation Program and was also opened to the academic scientific community. One of the attributes of the LIL facility is to be very flexible to accommodate the requests of plasma physicists during campaigns. The LIL is constantly evolving to best meet the needs of target physicists. Changes made or planned are either to improve the quality of laser beams, or to increase the LIL Energy-Power operating space. To optimize preparation and design of shot campaigns, the LIL performance status has been elaborated. It gives information about the characteristics of the laser in terms of near field and far field, defines the steps to maintain performance, explains how the facility responds to the request, details settings (smoothing, shaping of the focal spot, energy, temporal pulse shaping, beam pointing) and gives the limits in energy and power. In this paper, an overview of the LIL performance is presented. (authors)

  16. Turkey in Cyprus: Changing the Status Quo

    Directory of Open Access Journals (Sweden)

    Azuolas Bagdonas

    2016-04-01

    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.

  8. 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

    2001-01-01

    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.

  18. Squeezed in the middle: The middle status trade creativity for focus.

    Science.gov (United States)

    Duguid, Michelle M; Goncalo, Jack A

    2015-10-01

    Classical research on social influence suggested that people are the most conforming in the middle of a status hierarchy as opposed to the top or bottom. Yet this promising line of research was abandoned before the psychological mechanism behind middle-status conformity had been identified. Moving beyond the early focus on conformity, we propose that the threat of status loss may make those with middle status more wary of advancing creative solutions in fear that they will be evaluated negatively. Using different manipulations of status and measures of creativity, we found that when being evaluated, middle-status individuals were less creative than either high-status or low-status individuals (Studies 1 and 2). In addition, we found that anxiety at the prospect of status loss also caused individuals with middle status to narrow their focus of attention and to think more convergently (Study 3). We delineate the consequences of power and status both theoretically and empirically by showing that, unlike status, the relationship between power and creativity is positive and linear (Study 4). By both measuring status (Studies 2 and 3) and by manipulating it directly (Study 5), we demonstrate that the threat of status loss explains the consequences of middle status. Finally, we discuss the theoretical implications of our results for future research on status and problem solving on tasks that require either focus or flexibility. PMID:26302435

  20. 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

    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.

    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. For indirect co-firing it is a fact that lime kiln gasifiers and the gasifiers in Lahti, Ruien and Getruidenberg, without extensive gas cleaning, are in a commercial scale and that years of operation experiences already have been earned, also with waste fuels. The energy conversion to electricity uses existing infrastructure and therefore the adoption requirements are very limited. What

  6. 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.

    1997-12-01

    There is a need for a universal power module for microsystems. This module should provide power conditioning, energy storage, and load matching for a variety of energy sources and loads such as microelectromechanical systems (MEMS) and wireless sensors and micro-robots. There are a variety of potential ambient and human powered energy sources, which can supply some of the power needs of the military. The challenge is to capture these available sources of electrical energy and condition them to meet the voltage, current, and overall power demands of field-deployable microelectronics and MEMs-based devices such as wireless sensors and micro-robots. Most natural and man-made energy sources found in the environment have a low specific power and are not generally available on a continuous basis. Likewise, human-based energy sources must be optimally managed to meet the power needs in the field. Therefore, a power supply must have the ability to capture the available energy and store it in such a manner to be useful to meet the mission requirements of the device that is connected to the source. It must continuously monitor the status of energy stored and determine the expected demands of the device. A microelectronics-based power management chip can be developed to meet these objectives. The major challenge in realizing this concept will be the design of an intelligent power-conditioning chip that consumes a minimum of power to perform the functions of power conditioning, storage, load matching, and status monitoring. The prototype power conditioning integrated circuit would be capable of delivering a peak power of 100 mW at 5 V. The nominal operating condition would be a very low duty cycle for a relatively high power load, and a low-power source available for long periods of time, or a moderate-power source available intermittently.

    In the new report, Energy Status NVE provides a unified presentation of statistics and facts about the Norwegian energy system. 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)

    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.

    Full Text Available Refractory status epilepticus is a potentially life-threatening medical emergency. It requires early diagnosis and treatment. There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED, i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits.

    Background A possible increase in thyroid cancer in the young represents the most critical health problem to be considered after the nuclear accident in Fukushima, Japan (March 2011), which is an important lesson from the Chernobyl disaster (April 1986). Although it was reported that childhood thyroid cancer had started to increase 3–5 yr after the Chernobyl accident, we speculate that the actual period of latency might have been shorter than reported, considering the delay in initiating thyroid surveillance in the then Soviet Union and also the lower quality of ultrasonographic testing in the 1980s. Our primary objectives in the present study were to identify any possible thyroid abnormality in young Fukushima citizens at a relatively early timepoint (20–30 months) after the accident, and also to strive to find a possible relationship among thyroid ultrasonographic findings, thyroid-relevant biochemical markers, and iodine-131 ground deposition in the locations of residence where they stayed during very early days after the accident. Methods and Findings This is a cross-sectional study. We targeted the Fukushima residents who were 18 yr old or younger (including fetuses) at the time of the accident. Our examinations comprised a questionnaire, thyroid ultrasonography, thyroid-related blood tests, and urinary iodine measurement. We analyzed a possible relationship among thyroid ultrasonographic findings (1,137 subjects), serum hormonal data (731 subjects), urinary iodine concentrations (770 subjects), and iodine-131 ground deposition (1,137 subjects). We did not find any significant relationship among these indicators, and no participant was diagnosed to contract thyroid cancer. Conclusions At the timepoint of 20–30 months after the accident, we did not confirm any discernible deleterious effects of the emitted radioactivity on the thyroid of young Fukushima residents. This is the first report in English detailing the thyroid status of young Fukushima

    International Nuclear Information System (INIS)

    The increase of power plant efficiency has always been the aim of power plant manufacturers and operators. Today, after the re-orientation of the worldwide market situation, it is necessary to newly assess the power plant efficiency in the field of competition and environment. The average efficiency of power plants presently ranges worldwide at about 30%, yet the status of available technology in the year 2000 permits efficiencies between 45 an 58% depending on the fuels used. VGB PowerTech has been monitoring the technical development of power generation for 80 years up to now. From our point of view, power plant technology still has a great development potential at its disposal. (orig.)

    Full Text Available Les habitants du village tseltal d’Aguacatenango se trouvent confrontés aujourd’hui à différents bouleversements, dont les plus importants sont la prochaine réorganisation administrative et politique et, depuis une vingtaine d’années, la diversification des référents religieux. Ces transformations les obligent à adapter ou à reformuler ce qui pour eux constitue « la tradition » et, par là même, leur identité. L’une de leur principale préoccupation concernant ces changements est la mise en danger de leur conception de la bonne administration des affaires publiques. Les questions de distribution des pouvoirs sont ainsi au cœur des discours sur les processus actuels de « modernisation » de la communauté. Cet article se propose de revenir sur leur approche particulière de la notion de pouvoir par l’analyse de la forme d’organisation actuelle de leur administration, le système de charges. L’outil conceptuel de « frontières épaisses » permet de faire apparaître, à la marge du système, d’autres espaces de pouvoir, moins visibles mais tout aussi effectifs pour la population. Cette réflexion nous donnera une vision plus générale des différentes sphères de pouvoir et de leurs frontières, permettant pour la suite une lecture plus simple des véritables enjeux des changements actuels et des possibles stratégies d’adaptation qui en découleront.The inhabitants of the Tzeltal village of Aguacatenango currently find themselves confronted with various upheavals, the most serious of which are the upcoming administrative and political reorganisation and, over the past twenty years, the diversification of religious tenets.

    Accelerator Test Facility (ATF) has already achieved the vertical emittance of GLC specification. In order to make the multi-bunch emittance achievement, high quality multi-bunch beam from photo-cathode rf gun was employed. The maximum allowable current was raised to 3 times more. From the study, it was found that the vacuum level of damping ring is related to the achieved vertical emittance. The ring scrubbing with high current accumulation made tail bunch emittance growth lower. We describe the status of multi-bunch emittance study together with the development status of the various emittance monitors and beam position monitors. (author)

    Full Text Available Status epilepticus (SE can be divided into two subgroups, convulsive status epilepticus (CSE and nonconvulsive status epilepticus (NCSE. NCSE is clinically characterized by recurrence or persistence of absence or complex partial seizures which unconsciousness persists. Seizures are lasted more than 30 minutes, and accompanied by mental and behavioral changes. Although the main feature is the change of level of consciousness, affective, memory, cognitive, speech, motor systems, behavioral and psychiatric disorders can be also seen. Electroencephalography (EEG is the single diagnostic method in this situation. NCSE constitutes approximately 25% of all SE, however it is thought that sometimes it is misdiagnosed and the incidence of NCSE may be higher. The causes are disorders of central nervous system (stroke, infection, trauma, tumor, and metabolic factors (hypoxia, renal diseases, drugs, failure to use antiepileptic drug. The treatment contains the standard therapy of SE. Short-acting benzodiazepines are preferred in initial treatment. For more resistant cases, loading of phenytoin is applied. If there is no response to treatment, midazolam and propofol additionally to barbiturates can be used. We aimed to present a case admitted to our ED with altered mental status and diagnosed as NCSE that is under-diagnosed.

  6. Wind Power Meteorology

    DEFF Research Database (Denmark)

    Lundtang Petersen, Erik; Mortensen, Niels Gylling; Landberg, Lars;

    Wind power meteorology has evolved as an applied science, firmly founded on boundary-layer meteorology, but with strong links to climatology and geography. It concerns itself with three main areas: siting of wind turbines, regional wind resource assessment, and short-term prediction of the wind...... resource. The history, status and perspectives of wind power meteorology are presented, with emphasis on physical considerations and on its practical application. Following a global view of the wind resource, the elements of boundary layer meteorology which are most important for wind energy are reviewed......: wind profiles and shear, turbulence and gust, and extreme winds. The data used in wind power meteorology stem mainly from three sources: onsite wind measurements, the synoptic networks, and the re-analysis projects. Wind climate analysis, wind resource estimation and siting further require a detailed...

  8. 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.

  10. Atomic power's powered atomiser

    International Nuclear Information System (INIS)

    As an extension of its traditional activities the United Kingdom Atomic Energy Authority (UKAEA) has developed a range of products and services. So far one of its most successful ventures has been the licensing of power fluidics technology in the hvac (heating, ventilation and air conditioning) market. Power Fluidics is the control of liquid or gas flows without the use of any moving parts. The UKAEA has developed the vortex amplifier, a control device, which has many potential applications, in which the process flow is throttled and turned down as the control flow is increased. The bistable flow diverter in which a coanda effect diverts the flow down one of two outlets has possible uses in the water industry as well. Another development is a device for controlling fluid droplet size in which a bistable converter has a feedback loop which ensures continuous switching of the flow. By opposing the nozzle outlets, the alternating flows collide in a controlled manner and droplet size can be controlled. (U.K.)

    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.

    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.

  14. 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.
