    This preliminary edition was prepared at the Board's request to help it establish a standardized terminology. It was produced by scanning the 99 French and English documents listed at the end of this Vocabulary. The documents include legislation concerning atomic energy and the transportation of radioactive materials, as well as the Board's publications, such as the Consultative Documents, Regulatory Documents and Notices. The terms included from the following areas are: radiation protection, reactor technology, nuclear fuel cycle, radioactive material packaging and transportation, radioactive waste management, uranium mines, and medical and industrial applications of radioelements. Also included are the titles of publications and the names of organizations and units. The vocabulary contains 2,589 concepts, sometimes accompanied by definitions, contexts or usage examples. Where terms have been standardized by the Canadian Committee for the Standardization of Nuclear Terminology, this has been indicated. Where possible, we have verified the terms using the TERMIUM, the Government of Canada Linguistic Data Bank. (author)

  3. The Atomic Energy Control Board and the uranium mining industry

    International Nuclear Information System (INIS)

    The Atomic Energy Control Board controls prescribed substances and nuclear facilities through a licensing system. It is only recently that this system has been applied to the uranium industry. There are four stages in the licensing procedure before a Mine-Mill Facility Operating Licence is issued: exploration requires an underground exploration permit; site approval is needed before the start of the development stage; development approval is required before the construction of the mill and waste management facilities and depends on the information in a preliminary safety report; the granting of a final operating licence occurs after the Board is satisfied with the final safety report, operating policies and principles, tailings management, and decommissioning plans. The Board has resource management policies designed to ensure that uranium reserves are available to meet Canada's needs. The administration of safeguards is also the Board's responsibility. (LL)

  17. Atomic Energy of Canada Limited annual report 1989-1990

    International Nuclear Information System (INIS)

    In 1990, after a comprehensive industry review, the Canadian government announced that steps would be taken to revitalize the nuclear industry. Canada's nuclear utilities made a commitment to bear a large share of the cost of nuclear research and development. Atomic Energy of Canada Limited (AECL) reported its first financial loss in twelve years, as anticipated at the start of the year. Four of the 20 CANDU reactors operating worldwide were in the top ten based on lifetime performance. By year-end one foreign and two domestic utilities had announced their intention to build more CANDU units. The federal government has agreed to stabilize AECL's research funding at 1989-90 levels ($31.5 million above levels planned in 1985), has authorized AECL to negotiate with New Brunswick to build Point Lepreau-2 as the prototype for the CANDU-3 reactor, and has allowed the restructuring of AECL so utility and private sector investors can become equity partners in AECL CANDU

  18. The Atomic Energy of Canada Limited (AECL) employee health study

    International Nuclear Information System (INIS)

    A preliminary examination of records relating to past Chalk River employees provides some reassurance that large numbers of cancer deaths that might be related to occupational radiation exposure do not exist in the groups of employees studied to the end of 1982. The lack of reliable information on deaths of ex-employees who left AECL for other employment prevented the inclusion of this group in this preliminary study. This information will presumably be obtained during the course of the more comprehensive Atomic Energy of Canada Ltd. employee health study. 6 refs

    Canada has been a leader in tritium handling technologies as a result of the successful CANDU reactor technology used for power production. Over the last 50 to 60 years, capabilities have been established in tritium handling and tritium management in CANDU stations, tritium removal processes for heavy and light water, tritium measurement and monitoring, and understanding the effects of tritium on the environment. This paper outlines details of tritium-related work currently being carried out at Atomic Energy of Canada Limited (AECL). It concerns the CECE (Combined Electrolysis and Catalytic Exchange) process for detritiation, tritium-compatible electrolysers, tritium permeation studies, and tritium powered batteries. It is worth noting that AECL offers a Tritium Safe-Handling Course to national and international participants, the course is a mixture of classroom sessions and hands-on practical exercises. The expertise and facilities available at AECL is ready to address technological needs of nuclear fusion and next-generation nuclear fission reactors related to tritium handling and related issues.

  9. The safety of Ontario's nuclear power reactors. A scientific and technical review. A submission to the Ontario Nuclear Safety Review by Atomic Energy Canada Limited

    International Nuclear Information System (INIS)

    This submission comments on the evolution of the Canadian nuclear program, the management of safety, and the reactor design, analysis, operation and research programs that contribute to the safety of the CANDU reactor and provide assurance of safety to the regulatory agency and to the public. The CANDU reactor system has been designed and developed with close cooperation between Atomic Energy of Canada Ltd. (AECL), utilities, manufacturers, and the Atomic Energy Control Board (AECB). The AECB has the responsibility, on behalf of the public, for establishing acceptable standards with respect to public risk and for establishing through independent review that these standards are satisfied. The plant designer has responsibility for defining how those standards will be met. The plant operator has responsibility for operating within the framework of those standards. The Canadian approach to safety design is based on the philosophy of defence in depth. Defence in depth is achieved through a high level of equipment quality, system redundancy and fail-safe design; regulating and process systems designed to maintain all process systems within acceptable operating parameters; and, independent safety systems to shut down the reactor, provide long-term cooling, and contain potential release of radioactivity in the event of an accident. The resulting design meets regulatory requirements not only in Canada but also in other countries. Probabilistic safety and risk evaluations show that the CANDU design offers a level of safety and least as good as other commercially available reactor designs

  11. A study of the health of the employees of Atomic Energy of Canada Limited. 1

    International Nuclear Information System (INIS)

    This report summarizes the status of Atomic Energy of Canada Ltd.'s health study of its present and past employees, and is a description of the steps which have been taken up to the time of writing. During the design phase there was a shift in the emphasis of the study. What was originally proposed as a study of mortality in a population of radiation workers, related spacifically to radiation exposure, has become a study of mortality data for all AECL employees. The interest in mortality as a function of occupational radiation expksure remains, but it is recognized that the data available to the study will probably be inadequate for the definition of a dose-effect relationship, although it will be useful in conjuction with other similar studies. The importance of cancer incidence is recognized, and the possibility of linking the AECL data to that contained in the National Cancer Incidence Reporting System is being pursued

    The dose management system (DMS) is a computer software developed by the International Atomic Energy Agency for managing data on occupational exposure to radiation sources and intake of radionuclides. It is an integrated system for the user-friendly storage, processing and control of all existing internal and external dosimetry data. The Radiation Protection Board (RPB) of the Ghana Atomic Energy Commission has installed, customised, tested and using the DMS as a comprehensive DMS to improve personnel and area monitoring in the country. Personnel dose records from the RPBs database from 2000 to 2009 are grouped into medical, industrial and education/research sectors. The medical sector dominated the list of monitored institutions in the country over the 10-y period representing ∼87 %, while the industrial and education/research sectors represent ∼9 and ∼4 %, respectively. The number of monitored personnel in the same period follows a similar trend with medical, industrial and education/research sectors representing ∼74, ∼17 and ∼9 %, respectively. Analysis of dose data for 2009 showed that there was no instance of a dose above the annual dose limit of 20 mSv, however, 2.7 % of the exposed workers received individual annual doses >1 mSv. The highest recorded individual annual dose and total collective dose in all sectors were 4.73 mSv and 159.84 man Sv, respectively. Workers in the medical sector received higher individual doses than in the other two sectors, and average dose per exposed worker in all sectors is 0.25 mSv.

  13. The bungling giant: Atomic Energy Canada Limited and next-generation nuclear technology, 1980--1994

    Science.gov (United States)

    Slater, Ian James

    From 1980--1994 Atomic Energy Canada Limited (AECL), the Crown Corporation responsible for the development of nuclear technology in Canada, ventured into the market for small-scale, decentralized power systems with the Slowpoke Energy System (SES), a 10MW nuclear reactor for space heating in urban and remote areas. The SES was designed to be "passively" or "inherently" safe, such that even the most catastrophic failure of the system would not result in a serious accident (e.g. a meltdown or an explosion). This Canadian initiative, a beneficiary of the National Energy Program, was the first and by far the most successful attempt at a passively safe, decentralized nuclear power system anywhere in the world. Part one uses archival documentation and interviews with project leaders to reconstruct the history of the SES. The standard explanations for the failure of the project, cheap oil, public resistance to the technology, and lack of commercial expertise, are rejected. Part two presents an alternative explanation for the failure of AECL to commercialize the SES. In short, technological momentum towards large-scale nuclear designs led to structural restrictions for the SES project. These restrictions manifested themselves internally to the company (e.g., marginalization of the SES) and externally to the company (e.g., licensing). In part three, the historical lessons of the SES are used to refine one of the central tenets of Popper's political philosophy, "piecemeal social engineering." Popper's presentation of the idea is lacking in detail; the analysis of the SES provides some empirical grounding for the concept. I argue that the institutions surrounding traditional nuclear power represent a form utopian social engineering, leading to consequences such as the suspension of civil liberties to guarantee security of the technology. The SES project was an example of a move from the utopian social engineering of large-scale centralized nuclear technology to the piecemeal

  16. Waste Management Improvement Initiatives at Atomic Energy of Canada Limited - 13091

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Limited's (AECL) Chalk River Laboratories (CRL) has been in operation for over 60 years. Radioactive, mixed, hazardous and non-hazardous wastes have been and continue to be generated at CRL as a result of research and development, radioisotope production, reactor operation and facility decommissioning activities. AECL has implemented several improvement initiatives at CRL to simplify the interface between waste generators and waste receivers: - Introduction of trained Waste Officers representing their facilities or activities at CRL; - Establishment of a Waste Management Customer Support Service as a Single-Point of Contact to provide guidance to waste generators for all waste management processes; and - Implementation of a streamlined approach for waste identification with emphasis on early identification of waste types and potential disposition paths. As a result of implementing these improvement initiatives, improvements in waste management and waste transfer efficiencies have been realized at CRL. These included: 1) waste generators contacting the Customer Support Service for information or guidance instead of various waste receivers; 2) more clear and consistent guidance provided to waste generators for waste management through the Customer Support Service; 3) more consistent and correct waste information provided to waste receivers through Waste Officers, resulting in reduced time and resources required for waste management (i.e., overall cost); 4) improved waste minimization and segregation approaches, as identified by in-house Waste Officers; and 5) enhanced communication between waste generators and waste management groups.

  18. Canada's radiation scandal?

    International Nuclear Information System (INIS)

    In July 1990, Greenpeace distributed a 16-page treatise entitled 'Canada's Radiation Scandal' to a wide audience. The bottom line of the Greenpeace critique was that 'Canada's radiation limits are among the worst in the developed world'. This is a commentary on the Greenpeace pamphlet from the Atomic Energy Control Board (AECB), the body that sets and enforces radiation standards covering the use of nuclear energy in Canadian industry, science and medicine

  19. Proposed Atomic Energy of Canada Ltd. 99Mo waste calcination process

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Limited (AECL), at its Chalk River Laboratory, generates from 3000 to 5000 L/year of high-level fissile waste solution from the production of 99Mo. In this Mo process, highly enriched uranium (93 wt % 235U, total uranium basis) contained in uranium-aluminum alloy target rods is irradiated to produce the 99Mo product. The targets are removed from the reactor and dissolved in a mercury nitrate-catalyzed reaction with nitric acid. The 99Mo product is then recovered by passing the solution through an alumina (Al2O3) column. During discussions with personnel from the Oak Ridge National Laboratory (ORNL) on September 10, 1992, the ORNL-developed technology formerly applied to the solidification of aqueous uranium waste (Consolidated Edison Uranium Solidification Program or CEUSP) was judged potentially applicable to the AECL 99Mo waste. Under a Work-for-Others contract (no. ERD-92-1132), which began May 24, 1993, ORNL was tasked to determine the feasibility of applying the CEUSP (or a similar) calcination process to solidify AECL's 99Mo waste for > 30 years of safe dry storage. This study was to provide sufficient detailed information on the applicability of a CEUSP-type waste solidification process to allow AECL to select the process which best suited its needs. As with the CEUSP process, evaporation of the waste and a simultaneously partial destruction of acid by reaction with formaldehyde followed by in situ waste can thermal denitration waste was chosen as the best means of solidification. Unlike the CEUSP material, the 99Mo waste has a considerable number of problem volatile and semivolatile constituents which must be recovered in the off-gas treatment system. Mercury removal before calcination was seen as the best option

    International Nuclear Information System (INIS)

    Through the Atomic Energy Act, Congress made is possible for the public to get a full and fair hearing on civilian nuclear matters. Individuals who are directly affected by any licensing action involving a facility producing or utilizing nuclear materials may participate in a formal hearing, on the record, before independent judges on the Atomic Safety and Licensing Board Panel (ASLBP or Panel). Frequently, in deciding whether a license, permit, amendment, or extension should be granted to a particular applicant, the Panel members must be more than mere umpires. If appropriate, they are authorized to go beyond the issues the parties place before them in order to identify, explore, and resolve significant questions involving threats to the public health and safety that come to a board's attention during the proceedings. This brochure explains the purpose of the panel. Also addressed are: type of hearing handled; method of public participation; formality of hearings; high-level waste; other panel responsibilities and litigation technology

  5. Energy in Canada

    International Nuclear Information System (INIS)

    Canada's historical energy consumption, its current consumption and its likely requirements by the turn of the century are reviewed. It is estimated that at least 50% more energy will be required in the year 2000 than is consumed now, assuming a minimum 2% growth rate in primary energy consumption. Both non-renewable and renewable energy resources are examined in the light of these future energy requirements and the need to substitute alternative energy sources for conventional oil in various end uses. The comparative risks involved in energy production are also reviewed. Most of the increase in energy consumption and the substitution of oil over the next 20 years is likely to be met by conventional energy sources, since indigenous reserves are extensive and the relevant technologies well-established. Coal, nuclear and hydro reserves could cover the increase in energy demand until well into the next century, and natural gas reserves are sufficient to bridge the gap during conversion from oil to other energy sources. Nuclear power using advanced fuel cycles and oil from tar sands offer Canada long-term security. The penetration of unconventional energy sources is likely to be relatively small during the next 20 years. However, the most promising may become significant in the next century. (author)

  6. An assessment of the Atomic Energy Control Board consultation process

    International Nuclear Information System (INIS)

    This report analyzes the consultation process followed by the AECB in discharging its responsibility for regulation development. It shows how the process could be improved by better targeting of the consultation towards groups that can be expected to provide valuable input. It also addresses the question of how best to convey to members of those groups the information they need before making comments on proposed regulatory changes. The study also looks at how effective the process is and at possible procedural improvements that might facilitate the preparation of comments by outside groups and improve the understanding among the public of the role played by the AECB and of the issues surrounding nuclear facilities and the use and handling of prescribed substances

    International Nuclear Information System (INIS)

    The National Energy Board hosted this Energy Futures Workshop as a follow-up to its report entitled Canada's Energy Future: Reference Case and Scenarios to 2030, which focused on emerging trends in energy supply and demand. Various energy futures that may be available to Canadians up to the year 2030 were examined. This workshop addressed issues regarding the growing demand for energy, the adequacy of future energy supplies, and related issues of greenhouse gas emissions, emerging technologies, energy infrastructure and energy exports. The workshop was attended by 18 experts who presented their diverse views on long-term energy issues. The sessions of the workshop focused on external and key geopolitical issues that will influence Canadian energy markets; the adoption of alternative and emerging sources of energy; outlook for Canadian oil supply, including oil sands development, reservoir quality, and financial, environmental and technological issues; issues in electricity generation and transmission; gas market dynamics; and carbon dioxide capture and storage and the associated benefits and challenges. There was general consensus that global and Canadian energy markets will remain in a state of flux. Crude oil prices are likely to remain high and volatile. The combination of maturing energy resource basins and geopolitical tensions has created uncertainty about future availability and access to global energy resources. 2 figs., 3 appendices

    This paper addresses several aspects of implementing a control system for electronics boards in order to perform remote Field Programmable Gate Array (FPGA) programming, hardware configuration, register control, and monitoring, as well as interfacing it to an expert system. The paper presents an implementation, using the Distributed Information Management (DIM) package and the industrial SCADA system PVSS II from ETM, in which the access mechanisms to the board resources are completely generic and in which the device prescription and the handling of mapping between functional parameters and physical registers follow a common structure independent of the board type. The control system also incorporates mechanisms by which it may be controlled from a finite state machine based expert system. Finally the paper suggests an improvement in which the mapping between logical parameters and physical registers is represented by descriptors in the device description such that the translation can be handled by a common m...

  18. CONTROL ENGINEERING ON BOARD

    Directory of Open Access Journals (Sweden)

    Serghei RADU

    2012-11-01

    Full Text Available Control engineering embraces instrumentation, alarm systems, control of machinery and plant previously known under the misnomer of automation. Control engineering can be applied not only to propelling and auxiliary machinery but also to electrical installations, refrigeration, cargo handling (especially in tankers and deck machinery, e.g. Windlass control. Opinion still vary on such matters as the relative merits of pneumatic versus electronic system and whether the control center should be in the engine room or adjacent to the navigating bridge. Arguments against the exclusion of the engineer officer from close contact with the machinery are countered by the fact that electronic systems are based on changes other than those of human response. Automated ships (UMS operate closer to prescribed standards and therefore operate with greater efficiency. The closer control of machinery operating conditions, e.g. cooling water temperatures and pressures, permits machinery to be run at its optimum design conditions, making for fuel economy and reduced maintenance. Automation can carry out some tasks far more effectively than men. In other areas it is less effective. For example, the monitoring of machinery operating conditions such as the temperatures and pressures can be carried out by a solid state alarm scanning system at the rate of 400 channels/sec., giving a degree of surveillance which would be impossible by human observation. Conversely, the detection of noisy bearing, a leaky gland or cracked pipe is scarcely possible by automatic means. The balance between the possible and the necessary would be achieved in this case by combining automatic monitoring of all the likely fault conditions, with routine machinery space inspection say twice a day.

    Petrone, Richard M.; Rouse, Wayne R.

    2000-08-01

    An objective hybrid classification of daily surface weather maps for central and western Canadian sub-arctic locations was used to determine their dominant synoptic conditions during the snow free period. This classification yielded seven dominant synoptic types for each location during the snowmelt and snow-free periods (20 April-7 September), accounting for 90% of the days in period. The effects of source regions were used to explain the observed air mass characteristics, and their influence on the respective study locations. Cooler, drier air masses were the most frequent at both study locations. Arctic high pressure cells to the northeast brought the coolest air to the western sub-arctic site, Trail Valley Creek (TVC), Northwest Territories, while high pressure systems approaching from the northwest brought the coolest conditions to the central sub-arctic site, Churchill, Manitoba. Sub-tropical high pressure approaching from the west-southwest brought warm air to TVC, whereas stationary high pressure to the south warmed Churchill. These synoptic regimes exerted strong controls on the precipitation and evaporation components of the water balance as observed in terms of cloud cover, radiation and precipitation and evaporation efficiencies.

  2. Canada

    International Nuclear Information System (INIS)

    Nuclear research and development in Canada started in the 1940s as a responsibility of the federal government. An engineering design team was established at Chalk River, Ontario, to carry out research on heavy water moderated lattices. A zero-energy heavy water moderated research reactor, ZEEP, was built and achieved criticality in September 1945; it was in fact the first human-made operating reactor outside the USA. In 1947, the 20 MW heavy water moderated national research experimental reactor (NRX) started up. It served as one of the most valuable research reactors in the world, and provided the basis for Canada's development of the very successful CANDU series of pressurised heavy water reactors (PHWR) for power generation. Atomic Energy of Canada Limited (AECL) was established in 1952 as a federal Crown Corporation. It has both a public and a commercial mandate. AECL has overall responsibility for Canada's nuclear research and development programme (its public mandate) as well as for the Canadian reactor design (CANDU), engineering and marketing programme (its commercial mandate). Nuclear energy in Canada is a $5 billion per-year industry, representing about 150 firms, 21 000 direct jobs and 10 000 indirect jobs, and ∼$1.2 billion in exports - the value to the country's economy is much higher than the research and development funding provided by the federal government. The CANDU nuclear reactor system was developed by AECL in close collaboration with the Canadian nuclear industry, and in particular with Ontario Hydro (now Ontario Power Generation). Currently, Canada operates 17 CANDU reactors, which contribute 16% of the country's current electricity consumption. There are also 12 CANDU reactors operating abroad (in Argentina, China, India, the Republic of Korea, Pakistan and Romania). AECL is now developing the 'third generation plus' Advanced CANDU Reactor (ACR-1000), and also has the leading role internationally in developing the Generation IV

  3. Judicial control power and technico-scientific expert opinion in the atomic energy lawsuit

    International Nuclear Information System (INIS)

    Czajka, judge in the atomic energy law senate of a Higher Administrative Court, underlines the judicial control function and independence. In lawsuits on nuclear power plant issues many technical questions cannot be adequately judged by lawyers as laymen so that they must use the help of experts. If possible, Czajka wants to hear in a discussion in court experts of different opinions. The appreciation of controversial expert opinions requires of the judge a judging decision which in the end cannot be logically stated. Though this subjective element of the evaluation of evidence is inevitable, Czajka defends himself by referring to the legal protection mandate of the courts against attempts of both sides to limit the judicial inquiry into facts by legal-dogmatic considerations.

    1994-12-31

    A new standard issued by the Canadian Standards Association, CSA C802, imposes maximum losses on transformers 10 MVA and below. Included are Distribution Transformers, small Power Transformers, and Dry Types. Implementation will start though the publishing in mid 1994 of the Gazette by Ontario`s Ministry of Energy. The Gazette will call for conformance to C802 after a lead time of one year to eighteen months, depending on the type of transformer. Other provincial energy ministries have been awaiting this development and are expected to follow suit shortly thereafter. The federal department, Natural Resources Canada, is also attuned to these actions and is expected to issue supportive legislation which will control movement of transformers across provincial and national borders.

    International Nuclear Information System (INIS)

    The nuclear regulatory process as it applies to uranium refineries and conversion facilities in Canada is reviewed. In the early 1980s, Eldorado Resources Limited proposed to construct and operate new facilities for refining yellowcake and for the production of uranium hexafluoride (UF6). These projects were subject to regulation by the Atomic Energy Control Board. A description of the Atomic Energy Control Board's comprehensive licensing process covering all stages of siting, construction, operation and eventual decommissioning of nuclear facilities is traced as it was applied to the Eldorado projects. The Atomic Energy Control Board's concern with occupational health and safety, with public health and safety and with protection of the environment so far as it affects public health and safety is emphasized. Some regulatory difficulties encountered during the project's development which led to opening up of the licensing process to public input and closer coordination of regulatory activities with other provincial and federal regulatory agencies are described. The Board's regulatory operational compliance program for U refineries and conversion facilities is summarized. (author)

    International Nuclear Information System (INIS)

    In 2001 Canada's energy industry accounted for about 6 per cent of Canada's Gross Domestic product and employed 293,000 people. The National Energy Board informs Canadians about energy market trends. This annual report provides a summary of Canadian energy supply, consumption, production, prices and trade with an emphasis on developments in 2001. The National Energy Board dealt with applications for new pipeline facilities, new international power lines, tolls and tariff filings as well as approvals for exploration and development activity north of sixty. The year 2001 began with record high natural gas prices throughout North America, a crisis in the electricity market in California, and the highest oil prices since the 1991 Gulf war. Normal levels in oil and gas prices returned by the spring of 2001. In 2001, the Canadian pipeline infrastructure responded well to the market demands, delivering approximately $85 billion of natural gas, crude oil and petroleum products. The notable change was that the Alliance Pipeline and Vector Pipeline systems were in their first year of full operation, providing alternatives to TransCanada PipeLines system to deliver western Canadian natural gas to central Canadian markets. These new pipelines have created more competition between pipeline systems. There has also been significant consolidation within the industry. The events of September 11, 2001 emphasized the need to ensure security of Canada's natural gas and oil pipeline infrastructure. Most pipelines have been pro-active in protecting the overall security of the pipeline network in Canada. The Board also ensures that pipelines are operated in a manner that protects the environment, conducting audits of the environmental programs of regulated companies. There were no incidents in 2001 that resulted in severe degradation of the environment in which Canadian pipelines operate. tabs., figs

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2008-07-15

    The Keystone Pipeline Project consists of a 1,235 km pipeline extending from Hardisty, Alberta to Haskett, Manitoba. It involves the construction of 2 new pipeline segments and the conversion of 1 segment of the TransCanada Pipelines Limited Mainline Line 100-1 from oil to gas service. The Canadian portion of the pipeline will connect, through a new line to be built in the United States to markets in Wood River and Patoka Illinois, providing access to western Canada crude oil producers to the southern Petroleum Administration Defence District (PADD) 2 region of the United states. In November 2007, TransCanada Keystone Pipeline GP Ltd. applied to the National Energy Board for approval of variances to some previously approved facilities which would in effect permit the construction of additional transmission facilities. Keystone planned to add 473 km of pipeline from the Nebraska/Kansas border to Cushing, Oklahoma (Cushing Extension). The company also applied for variance in the associated tolling methodologies. In particular, Keystone requested to increase the motor sizes of 20 pumping units at 7 pump stations forming part of the facilities approved in the OH-1-2007 proceedings, and requested for the relocation of 3 pumping stations. Keystone also requested that the Board exempt it from the provisions of section 30 through 32 as required of the National Energy Board Act in respect of the proposed new facilities. The company also endeavored to obtain toll methodology, pursuant to Part 4 of the Act, for the Cushing Expansion shipper. This document presented the Board's view in terms of economics of the project; traffic tolls and tariffs; engineering; land matters; public and Aboriginal consultation; and environmental and socio-economic matters. Having considered all the evidence before it, the Board was satisfied that it is in the public interest to approve the Cushing Expansion Project. The Board also considered the proposed toll methodology and found it to be

  15. Energy in Canada: An overview

    International Nuclear Information System (INIS)

    Recent changes in the North American natural gas industry are discussed, with a focus on how these changes will affect the ability of Alberta and Canadian natural gas supply to meet market growth. These changes include a decline in the merchant role of many of the major interstate pipelines, resulting in a larger number of smaller-sized purchasers for natural gas marketers to deal with; a greater extent of direct purchasing by local distribution companies and large industrial users, combined with a preference for spot sales rather than long-term commitments; direct marketing of uncontracted gas by many producers and brokers; a bidding type of sales process rather than a negotiated process; and price deregulation. It is foreseen that long term security of supply will again become an important factor to North American buyers, and Canada can offer substantial supplies under secure long term contracts. Marketers will have to seek new market targets such as cogeneration plants and the transportation sector. Access to pipeline transport will be one of the major factors in obtaining new markets. The Canada-USA free trade agreement is viewed as a positive development which should help Canadian gas marketers to gain and retain U.S. customers

    International Nuclear Information System (INIS)

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and

    De Beers Canada Inc. plans to open the Victor Mine, a new diamond mine located 90 km west of the First Nations community of Attawapiskat in Northern Ontario. Both Hydro One and Five Nations Energy Inc. (FNEI) are the licensed power transmitters in the area. As such, these 3 stakeholders jointly applied to the Ontario Energy Board in late December 2004 to construct certain power transmission facilities. This application refers to the construction of transmission facilities that will connect De Beers' proposed Victor Mine to FNEI's transmission system. The joint application was revised in April 2005 to propose the construction of a 100 km single circuit 115 kV transmission line with 477 kilo-circular-mil (kcmil) conductor between the Victor Mine and FNEI's transformer station at Attawapiskat. It also proposed a 170 km single circuit 115 kV transmission line with 477 kcmil conductor between the transmission station at Kashechewan and Hydro One's Moosonee Switching Station and a 144 km of single circuit 115 kV transmission line with 795 kcmil conductor between Hydro One's Moosonee switching station and Hydro One's facilities at Otter Rapids generating station. The project also includes a new transmission station and associated facilities at the Victor Mine, modifications to FNEI's transmission stations at Attawapiskat and Kashechewan, and modifications to Hydro One's Moosonee switching station and facilities at Otter Rapids generating station. The estimated cost of the proposed facilities is $93.6 million. The Board noted that the project is needed to provide electrical supply to the Mine in 2007. The Board also examined whether the capital costs and operating, maintenance and administrative costs for the project were reasonable. It questioned what impact the project will have on transmission rates, and on reliability of supply. It also questioned whether the joint applicants have taken measures to mitigate power losses on the

  19. Atomic energy utilization

    International Nuclear Information System (INIS)

    As observed worldwide, sufficient consensus has not been obtained on the peaceful utilization of atomic energy, but why has only France showed the relatively smooth advance ? Is it the result of the PR activities by enterprises ? The author visited two French nuclear facilities in June-July, 1990, and experienced the way of acceptance of the peaceful utilization of atomic energy and the action of enterprises in France. The French Electric Power Corp. (EDF) already clarified the guideline to the society about 'How to obtain the trust of public for atomic energy'. The gist of the contents of this EDF guideline is shown. The investigation by the authors can be judged as illustrating concretely the posture of enterprises to endeavor for the realization of this EDF guideline. The serious consideration on communication and community, the opening of information to public and sincere response, the fostering of the expression techniques of those in charge of PR, the immediate notice at the time of accidents, the maintenance of information transmission systems and so on carried out for 30 years contributed to the fostering of trust. The points of social psychology for national consensus and the investigation in the La Hague reprocessing plant and the Super Phenix in Creys Malville are reported. (K.I.)

    2003-07-01

    A major international experiment, demonstrating technologies for tunnel sealing at full-scale, is being conducted at Canada's Underground Research Laboratory (URL) with participation by organizations from Canada, Japan, France and the U.S.A. Two bulkheads, one composed of high performance concrete and the other of highly compacted sand-bentonite material, have been constructed in a tunnel in unfractured granitic rock at the URL. The results from the Tunnel Sealing Experiment (TSX) are being used to characterize the performance of the two bulkheads under applied hydraulic pressures. The chamber between the two bulkheads has been pressurized to 4 MPa, a value representative of the natural hydrostatic heads at the 420 m depth below the ground surface. Instrumentation has been installed throughout the clay bulkhead to monitor stress development, bulkhead strain, moisture conditions, temperature, and water transport through this clay-based barrier. Construction was completed in 1998 October, and the sand-filled chamber between the clay and concrete bulkheads was filled and pressurized with water. Full pressure of 4 MPa was achieved in 2001 September and by 2002 June nearly complete saturation of the clay bulkhead was indicated. The rapid rate of saturation of the bulkhead (<5 years) is attributed initial large-flow events that caused a full perimeter water supply and allowed input of a considerable volume of water into the core of the bulkhead. Seepage through the clay bulkhead has been measured to be approximately 1.1 L/day under a 4 MPa pressure gradient across the 3.5 x 4.4 x 2.7 m length bulkhead. The majority of the seepage appears to be via the lower density outer perimeter of the bulkhead. Tracer tests have been completed which allow for assessment of flow times and pathways within the clay bulkhead. On achieving essentially full saturation, Phase 1 of the TSX was completed. A second phase of this experiment has recently (2002 June) begun with the

  2. Canada, Atomic Energy of Canada Limited (AECL), Chalk River Labs: Reuse and Licence Termination of a Number of Facilities at the Chalk River Labs to Allow for Refurbishment of the Site. Annex A. I-1

    International Nuclear Information System (INIS)

    Chalk River Labs is located along the Ottawa River in Ontario, Canada, approximately 200 km north-west of Ottawa. The site began construction in 1944 following the expropriation of approximately 1 500 ha of land. A number of research reactors were constructed at the site along with numerous nuclear labs, hot cells and administrative facilities in support of the research and development work planned for the site. The principal occupants of the Chalk River site are AECL employees with a strong presence from National Resources Canada (NRC) and other small research groups. The site is undergoing substantial changes with an emphasis on minimizing the impact of increasing the builtup area footprint in conjunction with site upgrades and new build projects. To accomplish this task, a number of refurbishment and decommissioning projects were planned. Decommissioning projects were initiated to make room for new development through a number of initiatives. The decommissioning mandate includes the removal of a select group of original deteriorating facilities to make room for new construction and to decommission other facilities to facilitate redevelopment and reuse of the available space. In Canada, the Canadian Nuclear Safety Commission (CNSC) issues nuclear licences. The licensees must demonstrate that it is safe to continue operations of the nuclear site and request a renewal of their licence. CNSC will issue a new operating licence for a specific period of time at which the licensee must demonstrate that it is safe to proceed with a licence renewal. A request to terminate a licensable activity must be submitted to the CNSC. Upon approval to proceed, it must be demonstrated that the licensable activities have ceased and the facility has been appropriately decommissioned. Licence termination requires a demonstration that the land or previous activities presents a low risk and that the process can be used to support redevelopment because it results in a scrutinized

    International Nuclear Information System (INIS)

    The Standing Committee on Energy, Mines and Resources of the House of Commons of Canada undertook a study of the economics of nuclear power in Canada. This is its report on the evidence it heard. It found that maintaining the nuclear power option is vital to Canada's interests. The Committee recommended that: the schedule for establishing a commercial high-level radioactive waste repository be advanced; the basic insurance coverage on nuclear facilities be raised; the federal government increase its financial support of Atomic Energy of Canada Ltd. (AECL); AECL expand its research and development activities, including non-nuclear R and D; AECL be allowed to hold a minority interest in any component of AECL that is privatized; any new entity created by privatization from AECL be required to remain under Canadian control; the Atomic Energy Control Act be altered to allow the Atomic Energy Control Board (AECB) to recover costs through licensing fees and user charges, while the AECB's parliamentary appropriation is increased to offset remaining costs of operations; membership on the AECB be increased from one to five full-time members, retaining the present four part-time members; the AECB hold its hearings in public; the name of the AECB be changed so it is more readily distinguishable from AECL; the AECB establish an office of public information; and that federal and provincial governments cooperate more closely to identify opportunities where more efficient use of electricity could be achieved and to promote those measures that can attain the greatest economic efficiency

    International Nuclear Information System (INIS)

    Hazards associated with surface sports, aquatic sports and exposure to radiation were considered at a meeting of the Canada Safety Council in late 1979. The session on radiation noted that 6 of 20000 radiation workers wearing dosimeters were exposed to a dose in excess of 5 rem, the annual limit set by the Atomic Energy Control Board. Radiographers were in the job classification receiving the highest doses of ionizing radiation. Concern was expressed for the emission of damaging radiation from broken mercury vapour lamps. Increased regulation rather than training was seen as the most effective solution. (T.I.)

    2016-08-01

    We propose a simple diatomic system trapped inside an optical cavity to control the energy flow between two thermal baths. Through the action of the baths the system is driven to a non-equilibrium steady state. Using the Large Deviation theory we show that the number of photons flowing between the two baths is dramatically different depending on the symmetry of the atomic states. Here we present a deterministic scheme to prepare symmetric and antisymmetric atomic states with the use of external driving fields, thus implementing an atomic control switch for the energy flow.

    Carey, S. K.; Knox, S.; Humphreys, E.

    2012-12-01

    The objectives of this study were to measure and evaluate the energy balance of a snowpack in a northern peatland, with a particular emphasis on the ground heat flux (G), and to evaluate the performance of a point energy and mass balance snowmelt model (SNOBAL) in peatland ecosystems. G is typically considered a small component of the snowpack energy balance (EB) when compared with radiative and turbulent fluxes. However, in environments where the soil temperature remains above freezing throughout the winter, G may be an important energy input to the snowpack. For direct assessment of the role of G in the snow energy budget of such an environment, the EB components of the snowpack at the Mer Bleue bog, a northern peatland, were directly measured and modelled using SNOBAL during the 2009-2010 winter. An 8 m tower mounted with a net radiometer, closed-path eddy covariance system, and supporting hydrometeorological instruments were used to quantify each form of energy transfer to the snowpack. In addition, snow surveys were conducted to determine snow depth, density, and snow water equivalent. When integrated over the pre-melt period, simulated and measured G proved to be a large contributor to the EB (25%). Net radiation and G were somewhat under-predicted by SNOBAL, whereas turbulent fluxes (especially latent heat fluxes, LE) were considerably over-predicted. G calculated by SNOBAL was found to be sensitive to the temperature gradient between the soil and the lower layer of the snowpack, whereas simulated turbulent fluxes were sensitive to the parameterization chosen to estimate roughness lengths for heat and water vapour.

    Financial information from TransCanada PipeLines Limited and a review of the company's 1998 operations was made available for the benefit of shareholders. TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

  18. Basic principles of radiation protection in Canada

    International Nuclear Information System (INIS)

    The major goal of radiation protection in Canada is to ensure that individuals are adequately protected against the harm that might arise from unwarranted exposure to ionizing radiation. This report deals with the basic principles and organizations involved in protection against ionizing radiation. Three basic principles of radiation protection are: 1) that no practice shall be adopted unless its introduction produces a positive net benefit for society, 2) that all exposures shall be kept as low as reasonably achievable, relevant economic and social factors being taken into account, and 3) that doses to individuals should not exceed specified annual limits. The limit for radiation workers is currently 50 mSv per year, and exposures of the general public should not exceed a small fraction of that of radiation workers. Other specific areas in radiation protection which have received considerable attention in Canada include limitations on collective dose (the sum of the individual doses for all exposed individuals), exemption rules for extremely small radiation doses or amounts of radioactive materials, occupational hazards in uranium mining, and special rules for protection of the foetus in pregnant female radiation workers. Implementation of radiation protection principles in Canada devolves upon the Atomic Energy Control Board, the Department of National Health and Welfare, provincial authorities, licensees and radiation workers. A brief description is given of the roles of each of these groups

    CERN Document Server

    Drukarev, Evgeny G

    2016-01-01

    This self-contained text introduces readers to the field of high-energy atomic physics - a new regime of photon-atom interactions in which the photon energies significantly exceed the atomic or molecular binding energies, and which opened up with the recent advent of new synchrotron sources. From a theoretical point of view, a small-parameter characteristic of the bound system emerged, making it possible to perform analytic perturbative calculations that can in turn serve as benchmarks for more powerful numerical computations. The first part of the book introduces readers to the foundations of this new regime and its theoretical treatment. In particular, the validity of the small-parameter perturbation expansion and of the lowest-order approximation is critically reviewed. The following chapters then apply these insights to various atomic processes, such as photoionization as a many-body problem, dominant mechanisms for the production of ions at higher energies, Compton scattering and ionization accompanied b...

  5. Radioactive Waste Control at the United Kingdom Atomic Energy Research Establishment, Harwell

    International Nuclear Information System (INIS)

    The paper outlines the present practices in the control and treatment of radioactive wastes at Harwell. The large-volume, low-level active liquid effluent is treated by phosphate coagulation methods and, eventually, discharged to the River Thames. The medium-level wastes are segregated and undergo a two-stage chemical treatment followed by passage through columns of Vermiculite. The latter process has been found to be effective in removing radoicaesium, which is not dealt with efficiently by the precipitation methods used. Liquid wastes with a high- activity content are stored and a new plant, incorporating chemical treatment, ion exchange and evaporation, is being installed. The chemical sludges formed in the treatment processes are dumped at sea after de-watering by filtration. The contaminated solid waste is either stored or disposed of at sea. It is important to reduce the volume as much as possible and the methods employed include pressure baling, melting and incineration of combustible matter. Small quantities of activity are discharged to the atmosphere through exhaust stacks. The cleaning of this discharge air is commonly achieved by the use of high-efficiency filters or liquid scrubbing systems. Regular stack monitoring is carried out and this is backed up by a comprehensive district sampling programme. (author)

  6. Energy Policies of IEA Countries - Canada -- 2009 Review

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2010-04-12

    Canada, with its diverse and balanced portfolio of energy resources, is one of the largest producers and exporters of energy among IEA member countries. The energy sector plays an increasingly important role for the Canadian economy and for global energy security, as its abundant resource base has the potential to deliver even greater volumes of energy. The federal, provincial and territorial governments of Canada are all strongly committed to the sustainable development of the country's natural resources and have a long-standing and informed awareness of the need for each to contribute to the development of the energy sector. Furthermore, the government of Canada seeks to achieve a balance between the environmentally responsible production and use of energy, the growth and competitiveness of the economy, and secure and competitively priced energy and infrastructure. Nonetheless, the long-term sustainability of the sector remains a challenge. Due to climatic, geographic and other factors, Canada is one of the highest per-capita CO2 emitters in the OECD and has higher energy intensity than any IEA member country. A comprehensive national energy efficiency strategy, coupled with a coordinated climate change policy targeted at the key emitting sectors, is needed. Carbon capture and storage (CCS) is a priority for the federal government and presents Canada with an opportunity to develop a new technology that can reduce greenhouse gas emissions on a large scale. The IEA recommends that Canada provide international leadership in the development of CCS technology. This review analyses the energy challenges facing Canada and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Canada towards a more sustainable energy future.

  11. Preemption - atomic energy

    International Nuclear Information System (INIS)

    While waiting for the federal government to develop a nuclear waste disposal strategy, California enacted legislation that bans the construction of nuclear reactors until permanent disposal technology for high-level wastes is demonstrated and approved. The US Supreme Court upheld this prohibition in Pacific Gas and Electric Co. v. State Energy Resources Conservation and Development Commission. The Court found that the California law did not attempt to regulate the construction or operation of a nuclear plant nor to infringe on federal regulation of radiation safety and nuclear wastes. The moratorium is a legitimate move by the state to avoid economic uncertainties. Federal preemption of the law would empower utilities to determine state energy needs and programs. 131 references

    Only three nuclear weapons produced by the Manhattan Project (MP) were used during World War II: Trinity Test, New Mexico on 16 July 1945, Hiroshima, Japan, on 6 August 1945, and Nagasaki, Japan, on 9 August 1945. Several sources and authors, including EM and RL (1967), Stacey (1970), Sanger (1981), and Buckley (2000), have written that it is unlikely that any Canadian uranium was used in the atomic weapons that ended WW II. These sources offer no detailed justification for their conclusion, nevertheless, after analysis of data contained in numerous sources, this article reaches a similar conclusion. (author)

  18. Atomic energy in Latin America

    International Nuclear Information System (INIS)

    Most countries in Latin America, including all those on the mainland, are Members of the Agency. Interest in the possibilities of nuclear energy has led to considerable activity, much of it in direct collaboration with the IAEA. Member States in the region are: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela. Of these, Argentina, Brazil, Colombia and Venezuela are operating, and Mexico and Uruguay are constructing, research reactors, while Chile and Peru are studying proposals. Argentina, Brazil, Mexico and Uruguay have all agreed to accept Agency safeguards for reactors. The possibility of future needs for nuclear power is under examination by several countries, in some cases being related to desalination of water. All atomic work in Latin America is devoted to peaceful uses, and note-worthy progress has been made with proposals for a treaty which would make the whole region a militarily de-nuclearized zone. It is proposed that when this comes into effect the Agency will be asked to apply the controls developed in its safeguards system, and to carry out the inspections necessary to establish that work in progress is solely for peaceful purposes

  19. Not Just the Facts: Adjudicator Bias and Decisions of the Immigration and Refugee Board of Canada (2006-2011

    Directory of Open Access Journals (Sweden)

    Innessa Colaiacovo

    2013-12-01

    Full Text Available The Immigration and Refugee Board of Canada (IRB is Canada’s largest administrative tribunal. The Refugee Protection Division (RPD of the IRB is responsible for the adjudication of refugee claims made from within Canada.  In accordance with its obligations under international law, Canada grants protection to persons who have a well-founded fear of persecution because of race, nationality, religion, political opinion, or membership in a particular social group. In addition, a person may request protection in Canada on the basis of his or her fear of torture, risk to life or risk of cruel and unusual treatment or punishment. Acceptance (approval rates of claims vary widely across members of the IRB, with some granting asylum in less than 10 percent of cases, and others granting asylum in more than 90 percent of cases. Despite this fact, there is a lack of analysis exploring whether grant rates vary systematically in relationship to observed characteristics of adjudicators. This paper presents statistical analysis of over 68,000 refugee claims adjudicated by 264 members of the board from 2006 to 2011. It finds that the probability of acceptance is associated with individual members’ characteristics including education, gender, and professional experience, when holding constant the claimant’s country of origin, gender, and the year and regional office of adjudication. The findings suggest that the identity of the adjudicator affects whether or not an individual receives asylum.

  2. Nitrogen-atom endohedral fullerene synthesis with high efficiency by controlling plasma-ion irradiation energy and C{sub 60} internal energy

    Energy Technology Data Exchange (ETDEWEB)

    Cho, Soon Cheon; Kaneko, Toshiro, E-mail: kaneko@ecei.tohoku.ac.jp; Ishida, Hiroyasu; Hatakeyama, Rikizo [Department of Electronic Engineering, Tohoku University, 6-6-05 Aoba, Aramaki, Aoba-ku, Sendai 980-8579 (Japan)

    2015-03-28

    The nitrogen-atom endohedral fullerene (N@C{sub 60}) has been synthesized by controlling the plasma ion irradiation energy (E{sub i}) and fullerene (C{sub 60}) behavior in the sublimation phase. We examined the relationship between the synthesis purity of N@C{sub 60} [molar concentration ratio of N@C{sub 60} to pristine fullerene (C{sub 60})] and E{sub i}, which was controlled by changing the substrate bias voltages (V{sub sub}) and gas pressure (P{sub N2}) during the plasma irradiation process. High-density nitrogen-molecular ions (N{sub 2}{sup +}) with a suitable E{sub i} near 80 eV are confirmed to be the optimum condition of the nitrogen plasma for the synthesis of high-purity N@C{sub 60}. In addition, high sublimation of C{sub 60} contributes to a higher yield due to the high internal energy of C{sub 60} and the related cage defects that are present under these conditions. As a result, a purity of 0.83% is realized for the first time, which is almost two orders of magnitude higher than that using other methods.

  3. The new Board of Governors

    International Nuclear Information System (INIS)

    Full text: Miss Blanche Margaret Meagher was elected chairman of the IAEA Board of Governors for 1964-65, after the new Board had been constituted at the Eighth Session of the General Conference in September. Since 1962 Miss Meagher has been Canadian Ambassador to Austria, and Canadian Governor of the Agency. Miss Meagher joined the Canadian Department of External Affairs in 1942, and has held a number of foreign diplomatic appointments; she has also served on Canadian delegations to the UN Educational, Scientific and Cultural Organization, the International Telecommunication Union, the Economic and Social Council of UN and the UN Disarmament Sub-Committee.

  4. Canada

    International Nuclear Information System (INIS)

    This paper reports that the Canadian oil and natural gas sector is in for another grim year in 1992. Further streamlining to enhance operating efficiencies and control costs is the first order of the day. About $4 billion worth of producing properties remains on the market, as corporate focus continues to shift to core properties. New management structures put in place in the last two years will be severely tested to improve the sector's financial performance. Massive write-downs in 1990 and 1991 have put balance sheets in much better shape for improved financial performance in the future. Although new long-term debt exceeded redemptions in 1991, largely because of debt- financing of major capital projects, individually most companies are in better shape through significant debt repayment or restructuring. The substantial reductions in interest rates will also help to enhance discretionary cash flow. At this stage, everything appears to be in place to expect that 1992 will represent the bottom of the down-cycle for Canada

  7. Nuclear energy's continuing benefits to Canada

    International Nuclear Information System (INIS)

    The goal of the Canadian nuclear power program when it began twenty years ago was to reduce Canadian dependence on imported coal. This goal has been met, with 35 percent of Ontario's electricity being produced by CANDU reactors. These reactors have been proven reliable and safe, and provide a considerable cost advantage over coal. The CANDU reactor was developed with the strengths and limitations of Canadian industry in mind, the newest stations have over 85 percent Canadian-manufactured components. A similar benefit should be found in many countries with manufacturing capabilities comparable to Canada's. The use of natural uranium as a fuel has been a wise choice both technically and economically. A new industry was created in Canada in order to gain an assured supply of heavy water. The personnel brought to or trained in Canada to work in all parts of the nuclear industry represent a valuable asset in themselves. Radioisotope exports are making a significant contribution. Nuclear power is likely to make its greatest impact in the next century, when it will be a necessity

  9. A survey of research programs in radiation protection in Canada

    International Nuclear Information System (INIS)

    A survey of research programs in Canada concerned with radiation protection was conducted in 1991-92 by the Joint Subcommittee on Regulatory Research (JSCRR) of the Atomic Energy Control Board (AECB) Advisory Committees on Radiological Protection and on Nuclear Safety. The purpose of this survey was to determine the current state of funding for this type of research in Canada. Funding for health-related radiation research in Canada is critical to establishing and maintaining a supply of trained professionals who can provide competent advice on health-related problems in radiation protection. The present report is an analysis of the information received in this survey. This survey concludes with the recommendation that the organization and definition of subprograms for the AECB Regulatory Research and Support Program should be completed as soon as possible. In this report the JSCRR should assist AECB staff in preparing a report in which priorities for research related to radiation protection are indicated. The sources of information noted at the end of the Discussion section of this report should be considered for this purpose. (author). 15 refs., 3 tabs

    2008-08-15

    This pamphlet described an energy efficiency program used by Banff National Park in Canada. The park spans 6641 square kilometres and is one of the world's largest protected domains. Banff National Park was the first park in Canada to sign an energy performance contract aimed at improving the energy efficiency of 88 of its buildings over a period of 10 years. Natural Resources Canada's Federal Buildings Initiative program worked with Parks Canada to assess energy efficiency opportunities and identify preliminary work needed to improve the buildings. The energy performance contract was designed to reduce energy consumption, water consumption and reduce greenhouse gas (GHG) emissions. Efficiency measures included the installation of high-efficiency refrigerators; improvements in building envelopes; the installation of front-loading washing machines and gas dryers; the installation of high-efficiency condensing boilers; the retrofitting of heating, ventilation, and air-conditioning (HVAC) controls; and the use of solar hot water collectors. An employee awareness program was used to educate and motivate building occupants. Information displays were also mounted at major centres throughout the park to inform visitors of the program and develop a sense of environmental awareness. It was concluded that the program will serve as a model for the entire parks system and help Parks Canada to develop a long-term plan for managing energy efficiency. 4 figs.

    International Nuclear Information System (INIS)

    One of the objectives of the reorganization process of Argentina's public sector was to transfer to the private sector some of the Nation's productive activities, including those concerning the nuclear field. As a consequence, by Decree No. 1540 of August 30, 1994, (B.O. 2-Dec-94), CNEA's functions were partially reorganized. According to Decree No. 1540, the National Atomic Energy Commission (CNEA) maintained the missions and functions established by Decree-Law No. 22.498/56, with the exception of the regulation and surveillance of nuclear activities and the nuclear power generation activities. For the fulfillment of these activities, both the National Board of Nuclear Regulation (Ente Nacional Regulador Nuclear - ENREN) and Nucleoelectrica Argentina S.A. (NASA), were created. The National Board of Nuclear Regulation (ENREN), as an autarchical entity reporting to the Presidency of the Nation, shall be administered by a Board of Directors and shall be responsible for surveying and controlling all nuclear activities, shall suggest regulations and standards to ensure radiological and nuclear safety, personal protection, a controlled use of nuclear materials, licensing and surveillance of nuclear installations, and compliance with international safeguards. Nucleoelectrica Argentina S.A. (NASA) shall be organised as a corporation, reporting to the Ministry of Economy and Public Works and Services (Ministerio de Economia y Obras y Servicios Publicos) who will approve its statures. NASA shall take care of nuclear power generation at the Atucha I and Embalse nuclear power plants, as well as the construction, start-up and operation of the Atucha II nuclear power plant. As far as royalties are concerned, the Decree obliges Nucleoelectrica Argentina S.A. to pay CNEA for the performance of research and development activities, and to the ENREN an yearly regulatory tax per megawatt of installed nuclear power generation capacity. Also, Nucleoelectrica Argentina S.A. is declared

    Lithography based on scanning probe microscopic techniques has considerable potential for accurate & localized deposition of material on the nanometer scale. Controlled deposition of metallic features with high purity and spatial accuracy is of great interest for circuit edit applications in the semiconductor industry, for plasmonics & nanophotonics and for basic research in surface enhanced Raman scattering & nanobiophysics. Within the context of metal deposition we will review the development of fountain pen nanochemistry and its most recent emulation Atomic Force Controlled Capillary Electrophoresis (ACCE). Using this latter development we will demonstrate achievement of unprecedented control of nanoparticle deposition using a three-electrode geometry. Three electrodes are attached: one on the outside of a metal coated glass probe, one on the inside of a hollow probe in a solution containing Au nanoparticles in the capillary, and a third on the surface where the writing takes place. The three electrodes provide electrical pulses for accurate control of deposition and retraction of the liquid from the surface overcoming the lack of control seen in both dip pen lithography & fountain pen nanochemistry when the tip contacts the surface. With this development, we demonstrate depositing a single 1.3 nm Au nanoparticle onto surfaces such as semiconductors.

  19. Toward an energy security strategy for Canada : a discussion paper

    International Nuclear Information System (INIS)

    Energy security strategies for Canada were presented in this paper. Article 6.05 of North American Free Trade Agreement (NAFTA) prohibits Canada from reducing the proportion of energy exported to the United States or Mexico. Between 1982 and 2002, natural gas consumption in Canada rose by 96 per cent while exports increased by 396 per cent. Crude oil consumption increased by 29 per cent, while exports rose by 595 per cent. Government practices have tended towards extracting and exporting resources as quickly as possible with no consideration to resource availability for future generations. In addition, much of the value of Canadian resources has been given to private corporations. The environment has been damaged in order to enable faster extraction, and First Nations, employees, and communities have been placed at the mercy of corporations and international markets. Canada's unique cultural and societal arrangements have not been protected. Four principles to address these concerns were presented: (1) managing non-renewable resources as responsible stewards and conserving their economic availability for future generations; (2) ensuring that the benefits from fossil fuels are invested in other forms of capital that will ensure the future prosperity and energy security of Canada; (3) ensuring that the extraction and use of resources has minimal impacts on the planet and (4) a re-direction of the proceeds from resource exploitation towards education, social and health services, land claims and land use settlements, and the elimination of poverty among First Nations people. It was suggested that energy-related jobs and workers should be protected through the development of an industrial strategy which includes investment in renewable energy development and re-training programs for workers. Consistent depoliticized policies are needed to reduce the impact on low-income Canadians of free-market price swings and the unavoidable costs of environmental protection. It was

  20. Falling behind - Canada's lost clean energy jobs

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2010-05-15

    With the depletion of conventional resources and the increasing concerns about the environment, emphasis has been put on developing clean energy. Clean energy is expected to become one of the main industrial sectors within the next decade, thus creating numerous jobs. While significant investments have been made by several countries to shift to clean energy, Canada is investing in highly polluting resources such as the tar sands. It is shown that if Canada were to match U.S. efforts in terms of clean energy on a per person basis, they would need to invest 11 billion additional dollars and this would result in the creation of 66,000 clean energy jobs. This paper showed that Canada is falling behind in terms of clean energy and the authors recommend that the Canadian government match U.S. investments and design policies in support of clean energy and put a price on carbon so as to favor the development of the clean energy sector and its consequent job creation.

    As the 21st century is expected to induce a Knowledge based society, responding to this kind of change on our own initiative could be achieved by establishing networks among atomic energy agencies with the Atomic Energy Portal Site in a pivotal role. Thus, enabling the knowledge information from each agency to be easily shared and utilized. Furthermore, it can contribute to further researches by providing accumulated knowledge in the atomic energy, such as research output and past achievements, and by avoiding the repetition of researches on the same subjects. It could also provide remote educational data to researchers and industrial experts in atomic energy, as well as atomic energy information for general public consistently, so that we can promote our confidence in atomic energy

    Gibbons, J.; Bjorkquist, S. [Ontario Clean Air Alliance, Toronto, ON (Canada)

    1999-06-29

    The Ontario Clean Air Alliance (OCAA), a coalition of 67 organizations, takes issue with the Ontario Energy Board`s draft document `Standard Supply Service Code`, particularly sections 2.2.2. and 2.5.2 which they claim are not in the public interest unless the Ontario government implements the OCAA`s recommended emission caps. The alliance is of the view that without strict new environmental regulations the proposed Code would encourage the use of coal for electricity generation. Public health, the environment, consumer interests, job creation and promotion of a competitive electricity market would all be jeopardized by this development, the alliance states. The argument is supported by extensive reference to the Final Report of the Ontario Market Design Committee (MDC) which also emphasized the importance of combining the introduction of competition with appropriate environmental regulations, singling out the emission cap and trade program, and recommending that it be launched concurrently with the electricity market opening for competition. The view of the MDC was that public support for restructuring would not be forthcoming in the absence of regulatory measures to control power plant emissions. 25 refs.

  8. FPGA based VME boards for Indus-2 timing control system

    International Nuclear Information System (INIS)

    FPGA based two VME boards are developed and deployed recently for Indus-2 timing control system at RRCAT Indore. New FPGA based 5-channel programmable (Coarse-Fine) delay generator board has replaced three 2-channel coarse and one 4-channel fine existing delay generator boards. Introduction of this board has improved the fine delay resolution (to 0.5ns) as well as channel to channel jitter (to 0.8ns) of the system. It has also improved the coarse delay resolution from previous 33ns to 8ns with the possibility to work at divided Indus-2 RF clock. These improved parameters have resulted in better injection rate of beam. Old coincidence generator board is also replaced with FPGA based newly developed Coincidence clock generator VME board, which has resulted in successful controlled filling of beam (single, multi and 3-symmetrical bucket filling) in Indus-2. Three more existing boards will be replaced by single FPGA based delay generator card in near future. This paper presents the design, test results and features of new boards. (author)

  13. Atomic energy indemnification system in Japan

    International Nuclear Information System (INIS)

    The Japanese legislation on the indemnification by atomic energy enterprisers for atomic energy damages, published in 1961 and enforced in 1962, includes the law concerning indemnification for atomic energy damages and the law concerning atomic energy damage indemnification contracts (hereafter referred to as ''the law concerning indemnification contracts''). While the Japanese laws are same as the foreign legislation in the provisions of the responsibility of atomic energy damages without the error of atomic energy enterprisers, exemption reasons are more important in this respect. When damages are due to exceptionally grave natural disasters or social disturbances, atomic energy enterprisers are exempted from the responsibility. Indemnification amounts are determined, but the Japanese laws do not limit then, different from the foreign regulations. The periods for demanding indemnification are not defined particularly in the law concerning indemnification contracts, and the general basic rules of the civil law are applied. As a result, the demand right terminates in 3 years after the injured persons find damage and offenders, and in 20 years since the unlawful act (Article 724, Civil law). The indemnification liability for atomic energy damages is focused on atomic energy enterprisers concerned in the same way as the foreign laws. The measures for assuring the execution of indemnification responsibility consist in principle of the firm conbination of the liability insurance contracts with private insurance companies and the indemnification contracts for atomic energy damages with the state. The damages of employes suffered in works are excluded from indemnification, which has been the main issue of discussion since the enactment of atomic energy laws. (Okada, K.)

  15. The state of energy efficiency in Canada : Office of Energy Efficiency Report 2003

    International Nuclear Information System (INIS)

    This report describes the progress of Canada's economic sectors in improving energy efficiency. It also demonstrates the contribution made by energy efficiency initiatives administered by Natural Resources Canada through its Office of Energy Efficiency (OEE). Since 1990, Canada's energy efficiency has improved by 10 per cent, for a saving of $10.7 billion in energy costs. Energy efficiency programs carry new significance with Canada's ratification of the Kyoto Protocol in 2002. Energy conservation reduces greenhouse gas (GHG) emissions that contribute to climate change. The OEE introduced the One-Tonne Challenge to encourage individuals to reduce personal GHG emissions by an average of one tonne per year by 2008-2012. The programs help Canadian use energy more wisely at home, work and travel. The OEE collects and analyzes energy efficiency data and trends from major energy-using sectors of the economy and publishes the results on an annual basis to compare changes in how Canadians use energy. Between 1990 and 2001, energy use in Canada increased by 14 per cent compared to the 25 per cent that would have taken place without energy efficiency measures. Energy-related GHG emissions were 44 megatonnes lower than they would have been without energy efficiency measures. As of March 2002, GHG emissions related to government operations were reduced by 24 per cent from 1990 levels

  17. Energy policies of IEA countries. Canada 1996 review

    International Nuclear Information System (INIS)

    This IEA report provides a comprehensive, in-depth assessment of the energy policies of Canada, including recommendations on future policy developments. The report acknowledges the marked shift of federal energy policy in the last decade away from heavy intervention to a more market-based approach. This has increased the strength and competitive position of Canada's energy producers, especially in oil and gas, and has provided more choice for consumers. Electricity, however, is an area that could benefit from a more market-based policy orientation. Federal provincial co-ordination is of fundamental importance. Other key issues highlighted in the review include the opportunities and challenges of international agreements on the environment, which increasingly drive energy policy decision-making; the adequacy and effectiveness of programmes to promote energy efficiency; and the balance and direction of energy research and development efforts. This report forms part of a series of periodic in-depth reviews conducted and discussed by the IEA Member countries on a four-year cycle. Short reviews of energy policy developments in all twenty-three Member countries are published annually in Energy Policies of IEA Countries. (author)

    Concerning with the relation of vection induced by the optokinetic stimulation and the body movement, especially we attended to the neck joint movement, which counteracted to the shoulder movement. Then, we analyzed the mechanisms of the sitting postural control by using the seesaw board. By the optokinetic stimulation through the head mounted display (H.M.D.), the vection was leaded, and it affected to the sway of the body on the seesaw board. In this experiment, we found that the movement of upper part of body except for the head was the same direction to the seesaw board but the head moved out of phase to the seesaw board. This phenomenon will be suggested that the unstable condition of sway is balanced by the counter swing of head and the neck muscle tonus is controlled by acting of the vestiburo-collic reflex.

  1. Small wind in Canada's energy future : fostering domestic manufacturers

    International Nuclear Information System (INIS)

    While large-scale wind power projects are sustaining a 30 per cent annual growth rate, residential-scale wind power is increasingly being adopted in Germany, Japan, and the United States. This presentation discussed the benefits associated with fostering strong domestic wind turbine markets in Canada. Small wind turbine markets typically consist of grid-connected, net-metered turbines of less than 1 kW, off-grid micro-turbines used for battery charging, and net-metered, grid-connected, mid-sized turbines larger than 10 kW used in farming and small business applications. Continued energy price hikes are expected to cause the rapid growth of distributed generation, and nearly half of the world's 10 to 300 kW wind turbine generator manufacturers are located in Canada. However, federal support for small-scale distributed wind systems is lacking, and financial incentives are needed to mature the technology in Canada and leverage private investment. The use of decentralized energy will help to prevent line losses and reduce peak demands on the electricity grid. Use of the technology offers farms and small businesses a revenue stream and can reduce energy costs and demands. It is also expected that small wind jobs in Canada will grow from 50 to 640 by 2025. It was concluded that in order to ensure small wind development, capital cost incentive levels must be coupled with good interconnection and permitting policies. In addition, minimum safety and performance standards must be developed, along with rebate policies and siting analysis methods. tabs., figs

    Despite the rapid advances in optical frequency standards, caesium fountain clocks retain a critical role as the most accurate primary frequency standards available. At the National Research Council Canada, we are working to develop a second generation caesium fountain clock. Work is currently underway to improve several systems of FCs1, such as the laser system and microwave local oscillator, which will be incorporated into its refurbished version, FCs2. In addition, we have added an optical pumping stage which has increased the detected atom number by over a factor of six. In collaboration with the National Physical Laboratory (NPL), we are planning on replacing the physics package of FCs1. We will report on several recent improvements to FCs1, along with our progress in the development of FCs2.

  5. International Atomic Energy Agency activities in decommissioning

    International Nuclear Information System (INIS)

    Full text: The International Atomic Energy Agency (IAEA) has been addressing the safety and technical issues of decommissioning for over 20 years, but their focus has been primarily on planning. Up to know, the activities have been on an ad hoc basis and sometimes, important issues have been missed. A new Action Plan on the Decommissioning of Nuclear Facilities has recently been approved by the Agency's board of Governors which will focus the Agency's efforts and ensure that our Member States' concerns are addressed. The new initiatives associated with this Action Plan will help ensure that decommissioning activities in the future are performed in a safe and coherent manner. The International Atomic Energy Agency (IAEA) has been preparing safety and technical documents concerning decommissioning since the mid-1980's. There have been over 30 documents prepared that provide safety requirements, guidance and supporting technical information. Many of these documents are over 10 years old and need updating. The main focus in the past has been on planning for decommissioning. During the past five years, a set of Safety Standards have been prepared and issued to provide safety requirements and guidance to Member States. However, decommissioning was never a real priority with the Agency, but was something that had to be addressed. To illustrate this point, the first requirements documents on decommissioning were issued as part of a Safety Requirements [1] on pre-disposal management of radioactive waste. It was felt that decommissioning did not deserve its own document because it was just part of the normal waste management process. The focus was mostly on waste management. The Agency has assisted Member States with the planning process for decommissioning. Most of these activities have been focused on nuclear power plants and research reactors. Now, support for the decommissioning of other types of facilities is being requested. The Agency is currently providing technical

  9. Health system regionalization in Canada's provincial and territorial health systems: do citizen governance boards represent, engage, and empower?

    Science.gov (United States)

    Chessie, Kelly

    2009-01-01

    Regionalization of the health care system, through the creation of sub-provincial service-delivery regions and governance authorities (i.e., regional health authorities, RHAs), has been a key part of Canadian health reform initiatives of the past two decades. Increased public participation in health care planning and service delivery is one of the explicit goals of regionalization. Based on a reanalysis of data from a 2001 survey of health system governors from 134 RHAs throughout Canada, this study explores the overall demographic composition of the citizen governance boards, as well as their responses to various opinion and attitude questions. To enable consideration of the extent to which these sites may support public deliberation and community development, overall responses are examined, as are responses within two subtypes of governors: system-experienced citizen governors and lay citizen governors--governors with or without previous health-system employment experience, respectively. The findings suggest that attention needs to be paid to these citizen governance boards if they are truly meant to be sites of citizen engagement in health policy and governance. PMID:19927411

A Train-the-trainer seminar has helped to create a foundation for a national renewable energy training strategy. Future goals include new training partners and more funding

  12. Semi-adaptive modal control of on-board electronic boards using an identification method

    International Nuclear Information System (INIS)

    Modal active control, based on a state model, is an efficient method of increasing the lifetime of electronic boards by using piezoelectric components. In the case of industrial mass production, dispersions lead to changes in mechanical and electromechanical properties. Moreover, initial operating conditions such as boundary conditions can change during the lifetime of the control and modify its efficiency and stability. Therefore, a semi-adaptive modal control strategy in deferred time is proposed to attenuate these problems. Firstly modal control gains are calculated by using a classical linear quadratic Gaussian algorithm with the nominal model including mode shapes. Then control I/O data are collected by an identification system that uses on-board piezoelectric components. A subspace method is implemented to estimate modal matrices in order to update the controller. The sensitivity of control performance to modal parameter variation is presented. Estimated control frequencies and modal damping are finally used to update modal control gains. The effectiveness of the proposed method is examined through numerical simulation and experimental tests in the case of boundary condition modifications. This adaptive modal control/identification design greatly increases the nominal robustness of the controller in the case of frequency shifts

    Tinto, Massimo; Prestage, John D; Armstrong, J W

    2008-01-01

    Recent advances in space-qualified atomic clocks (low-mass, low power-consumption, frequency stability comparable to that of ground-based clocks) can enable interplanetary spacecraft radio science experiments at unprecedented Doppler sensitivities. The addition of an on-board digital receiver would allow the up- and down-link Doppler frequencies to be measured separately. Such separate, high-quality measurements allow optimal data combinations that suppress the currently-leading noise sources: phase scintillation noise from the Earth's atmosphere and Doppler noise caused by mechanical vibrations of the ground antenna. Here we provide a general expression for the optimal combination of ground and on-board Doppler data and compute the sensitivity such a system would have to low-frequency gravitational waves (GWs). Assuming a plasma scintillation noise calibration comparable to that already demonstrated with the multi-link CASSINI radio system, the space-clock/digital-receiver instrumentation enhancements would ...

  17. Regulatory challenges of historic uranium mines in Canada

    International Nuclear Information System (INIS)

    The radium and uranium mining industry began in Canada in 1930 with the discovery of the Port Radium deposit in the Northwest Territories. During the 1950s more uranium mines opened across Canada. Most of these mines ceased operation by the end of the 1960s. Some were remediated by their owners, while others were abandoned. The Atomic Energy Control Board (AECB), predecessor to the Canadian Nuclear Safety Commission (CNSC), was created in 1946. However, it was not until the mid-1970s that the AECB took an active role in regulating health, safety and environmental aspects of uranium mining; so many of the older mines have never been licensed. With the coming into force of the Nuclear Safety and Control Act (NSCA) in May 2000, this situation has been reviewed. The NSCA requires a licence for the possession of nuclear substances (including uranium mine tailings), or the decommissioning of nuclear facilities (including uranium mines and mills). Furthermore, governments (federal and provincial) are also subject to the NSCA, a change from the previous legislation. The CNSC has an obligation to assess these sites, regardless of ownership, and to proceed with licensing or other appropriate regulatory action. The CNSC has reviewed the status of the twenty sites in Canada where uranium milling took place historically. Eight are already licensed. Licensing actions are being pursued at the other sites. A review of nearly 100 small uranium mining or exploration sites is also underway to determine the most appropriate regulatory approach. This paper focuses on regulatory issues surrounding the historic mining and milling sites, and the regulatory approach being taken, including licensing provincial and federal government bodies who own some of the sites, and ensuring the safe management of sites that were abandoned.

  19. The regulation of uranium refineries and conversion facilities in Canada

    International Nuclear Information System (INIS)

    The nuclear regulatory process as it applies to uranium refineries and conversion facilities in Canada is reviewed. In the early 1980s, Eldorado Resources Limited proposed to construct and operate new facilities for refining yellowcake and for the production of uranium hexafluoride (UF6). These projects were subject to regulation by the Atomic Energy Control Board (AECB). A description of the AECB's comprehensive licensing process covering all stages of siting, construction, operation and eventual decommissioning of nuclear facilities is traced as it was applied to the Eldorado projects. The AECB's concern with occupational health and safety, with public health and safety and with the protection of the environment in so far as it affects public health and safety is emphasized. Some regulatory difficulties encountered during the project's development which led to opening up the licensing process to public input and closer coordination of regulatory activities with other provincial and federal regulatory agencies are described. The Board's regulatory operational compliance program for uranium refineries and conversion facilities is summarized

    As one of the channels by which board directors build important relationships,board networks can affect the governance role of independent directors. Defining director board networks as their connections based on direct ties they establish when serving on at least one common board, this paper explores the role of the network centrality of independent directors in restraining tunneling behavior by controlling shareholders in the Chinese capital market.Our empirical evidence shows that tunneling behavior by controlling shareholders is negatively related to the network centrality of independent directors and that this relationship is stronger when non-operating fund occupation is used as the measure of tunneling. The results of our study show that board networks can help independent directors to restrain tunneling behavior by large shareholders, which plays a positive role in corporate governance.ó 2013 Production and hosting by Elsevier B.V. on behalf of China Journal of Accounting Research.

    Feedback Control of MEMS to Atoms illustrates the use of control and control systems as an essential part of functioning integrated miniaturized systems. The book is organized according to the dimensional scale of the problem, starting with microscale systems and ending with atomic-scale systems. Similar to macroscale machines and processes, control systems can play a major role in improving the performance of micro- and nanoscale systems and in enabling new capabilities that would otherwise not be possible. The majority of problems at these scales present many new challenges that go beyond the current state-of-the-art in control theory and engineering. This is a result of the multidisciplinary nature of micro/nanotechnology, which requires the merging of control engineering with physics, biology and chemistry.

  2. The Future of Atomic Energy

    Science.gov (United States)

    Fermi, E.

    1946-05-27

    There is definitely a technical possibility that atomic power may gradually develop into one of the principal sources of useful power. If this expectation will prove correct, great advantages can be expected to come from the fact that the weight of the fuel is almost negligible. This feature may be particularly valuable for making power available to regions of difficult access and far from deposits of coal. It also may prove a great asset in mobile power units for example in a power plant for ship propulsion. On the negative side there are some technical limitations to be applicability of atomic power of which perhaps the most serious is the impossibility of constructing light power units; also there will be some peculiar difficulties in operating atomic plants, as for example the necessity of handling highly radioactive substances which will necessitate, at least for some considerable period, the use of specially skilled personnel for the operation. But the chief obstacle in the way of developing atomic power will be the difficulty of organizing a large scale industrial development in an internationally safe way. This presents actually problems much more difficult to solve than any of the technical developments that are necessary, It will require an unusual amount of statesmanship to balance properly the necessity of allaying the international suspicion that arises from withholding technical secrets against the obvious danger of dumping the details of the procedures for an extremely dangerous new method of warfare on a world that may not yet be prepared to renounce war. Furthermore, the proper balance should be found in the relatively short time that will elapse before the 'secrets' will naturally become open knowledge by rediscovery on part of the scientists and engineers of other countries.

    International Nuclear Information System (INIS)

    This new publication informs readers about what the Alberta Energy and Utilities Board (EUB) did in the past year, including important regulatory issues, trends and initiatives. The EUB is an agency of the provincial government, established to regulate Alberta's energy resource and utility sectors. It is part of the Alberta Ministry of Energy. The four main functions of the Board are regulatory initiatives, license applications, enforcement and information. This publication summarized the EUB's position regarding flaring (both solution gas flaring and well test flaring), and Board activities in the areas of animal health concerns, the gas over bitumen controversy, the deregulation of the electric industry and what it means to the EUB, improvements in data quality as a result of improved industry compliance in reporting, and a variety of issues related to the oil sands and the negotiated settlement process. Also, the Board has been proactive in the area of oilfield waste management guidelines, proliferation policies for gas processing facilities, sulphur recovery guidelines, and the expansion of the orphan well program to include facilities and pipelines. As a measure of the success of the EUB, a recent survey of 19 randomly selected focus groups praised EUB for its impartiality, fair and equitable enforcement and independence. It was also praised for its technically competent and experienced staff, its access to quality information and the clarity of its mandate, regulatory requirements and processes. The Board's efforts in the area of timely stakeholder consultation was highlighted. tabs., figs

  9. Ps-atom scattering at low energies

    Fabrikant, I I

    2015-01-01

    A pseudopotential for positronium-atom interaction, based on electron-atom and positron-atom phase shifts, is constructed, and the phase shifts for Ps-Kr and Ps-Ar scattering are calculated. This approach allows us to extend the Ps-atom cross sections, obtained previously in the impulse approximation [Phys. Rev. Lett. 112, 243201 (2014)], to energies below the Ps ionization threshold. Although experimental data are not available in this low-energy region, our results describe well the tendency of the measured cross sections to drop with decreasing velocity at $v<1$ a.u. Our results show that the effect of the Ps-atom van der Waals interaction is weak compared to the polarization interaction in electron-atom and positron-atom scattering. As a result, the Ps scattering length for both Ar and Kr is positive, and the Ramsauer-Townsend minimum is not observed for Ps scattering from these targets. This makes Ps scattering quite different from electron scattering in the low-energy region, in contrast to the inter...

  11. Exploration fuel : new computer modelling system allows exploration of Canada's potential energy future

    International Nuclear Information System (INIS)

    Without significant development of Canada's unconventional gas supplies and a reduction in Canada's natural gas use, Canada will become a net importer of natural gas by 2023, a fact which will have a major impact on oil sands production. This article described a computer model designed to consider Canada's potential energy future in relation to both natural gas supply and demand without considering price. The modelling study showed that new technologies are needed to reduce the amounts of energy used to produce Canada's oil sands resources. Methods such as toe-to-heel air injection (THAI) will provide a more efficient alternative to steam assisted gravity drainage (SAGD). The Canadian energy systems simulator (CanESS) was designed to interconnect up to 800 variables, and incorporates data points from Statistics Canada. The model is comprised of quantitative data and a physical economy model. It was concluded that the model can be used to explore the implications of energy policy options. 2 fig

    Predki, Pawel

    2011-01-01

    High availability and reliability are among the most desirable features of control systems in modern High-Energy Physics (HEP) and other big-scale scientific experiments. One of the recent developments that has influenced this field was the emergence of the Advanced Telecommunications Computing Architecture (ATCA). Designed for the telecommunications industry it has been successfully applied in other domains such as accelerator control systems. A good example is the application of ATCA stan- dard for the design of Low Level RF (LLRF) control system for the X-Ray Free Electron Laser (XFEL) being developed in Deutsches Elektronen Synchrotron (DESY). Reliability and availability requirements for such a device play a crucial role among other parameters. Thus, the ATCA standard, with five- nines availability, is considered one of the best candidates for this system. This article focuses on the central management unit of every ATCA board, namely the Intelligent Platform Management Controller (IPMC), developed for t...

  2. Does nuclear energy have a role in the development of Canada's oil sands?

    International Nuclear Information System (INIS)

    The Canadian Energy Research Institute (CERI) completed a study for Atomic Energy of Canada Limited (AECL) that compares the economics of a modified ACR-700 Advanced CANDU Reactor with the economics of a natural gas-fired facility to supply steam to a hypothetical Steam Assisted Gravity Drainage (SAGD) project located in northeastern Alberta. The results were initially presented at the Petroleum Society's Canadian International Petroleum Conference 2003, Calgary, Alberta, Canada, June 10-12, 2003. The comparison was made by using discounted cash-flow methodology to estimate the levelized unit cost of steam that could be supplied to the SAGD project from either a nuclear or a gas-fired facility. The unit cost of steam was determined by treating the steam supply facility as a standalone business; it would ensure that all costs are recovered including capital costs, operating costs, fuel costs, and a return on investment. The study indicated that steam supply form an ACR-700 nuclear facility is economically competitive with stea supply from a gas-fired facility. An examination of key variables indicated that the cost of steam form the nuclear facility is very sensitive to the capital cost of the facility, while the cost of steam from the gas-fired facility is very sensitive to the price of natural gas and possible Kyoto Protocol compliance costs.

    In this work, atomic calculations were performed within the local-density and generalized-gradient approximations of exchange and correlation density functionals within density-functional theory to provide accurate periodic trends of first ionization energies and electron affinities of the atomic series from hydrogen to xenon. Electronegativities were determined directly from Mulliken's formula and were shown to be equivalently calculated rather by using Slater-Janak's transition state or by calculating the electrostatic self-energies of the orbitals involved in the transition to ions. Finally, comparisons were made with other theoretical and experimental results, including Mulliken-Jaff\\'e's electronegativity scale.

  7. Peaceful uses of atomic energy

    International Nuclear Information System (INIS)

    The IAEA's statutory mandate is to promote all applications of nuclear energy for peaceful purposes. While non-power applications - in agriculture, medicine, industry, etc. - have become widely used and mostly accepted, nuclear power has become more controversial and is facing serious public acceptance problems. Public concern centres on three issues - radioactive wastes, nuclear accidents and the risk of nuclear weapons proliferation. Any discussion of the acceptability or desirability of nuclear power is meaningful only if the alternatives are considered in parallel. The role of nuclear power and other energy sources in electricity generation is discussed and the factors in favour of nuclear energy outlined. Although the Chernobyl accident had strong impact on public opinion in many countries, it has until now had small direct impact on the prospects of nuclear power in the world as a whole. The IAEA's nuclear safety activities and the post-Chernobyl strengthening of international cooperation to minimise nuclear accident consequences are described. The IAEA's safeguards system and its application to Australia's uranium are reviewed. Through this system with its on-site inspections, the IAEA continuously verifies that nuclear materials and nuclear installations submitted to it (some 95% of all fissionable material and of all installations in non-nuclear weapon states) remain in exclusively peaceful use

    Quantum technologies will ultimately require manipulating many-body quantum systems with high precision. Cold atom experiments represent a stepping stone in that direction: a high degree of control has been achieved on systems of increasing complexity. However, this control is still sub-optimal. In many scenarios, achieving a fast transformation is crucial to fight against decoherence and imperfection effects. Optimal control theory is believed to be the ideal candidate to bridge the gap between early stage proof-of-principle demonstrations and experimental protocols suitable for practical applications. Indeed, it can engineer protocols at the quantum speed limit – the fastest achievable timescale of the transformation. Here, we demonstrate such potential by computing theoretically and verifying experimentally the optimal transformations in two very different interacting systems: the coherent manipulation of motional states of an atomic Bose-Einstein condensate and the crossing of a quantum phase transition in small systems of cold atoms in optical lattices. We also show that such processes are robust with respect to perturbations, including temperature and atom number fluctuations.

    Neutral Holmium with its large number of hyperfine ground states provides a promising approach for collective encoding of a multi-qubit register. A prerequisite for collective encoding is the ability to prepare different states in the 128 state hyperfine ground manifold. We report progress towards optical pumping and control of the hyperfine Zeeman state of trapped Ho atoms. Atoms are transferred from a 410.5 nm MOT into a 455 nm optical dipole trap. The atoms can be optically pumped using light driving the ground 6s2 , F = 11 to 6 s 6 p ,F' = 11 transition together with a F = 10 to F' = 11 repumper.

  11. Three Essays on Energy Efficiency and Environmental Policies in Canada

    Science.gov (United States)

    Gamtessa, Samuel

    2011-09-01

    This thesis is organized into five Chapters. In Chapter 1, we provide an introduction. In Chapter 2, we present a study on residential energy-efficiency retrofits in Canada. We describe the EnerGuide for Houses data and model household decisions to invest in energy-efficiency retrofits. Our results show that government financial incentives have important positive effects. The decision to invest in energy-efficiency retrofits is positively related to potential energy cost savings and negatively related to the costs of the retrofits. We find that household characteristics such as the age composition of household members are important factors. All else remaining constant, low income households are more likely to undertake energy-efficiency retrofits. In the third Chapter, we present our study on price-induced energy efficiency improvements in Canadian manufacturing. Our study employs a new approach to the estimation of price-induced energy efficiency improvements and the results have important empirical and policy implications. In the fourth chapter, we present our study on the implications of the "shale gas revolution" on Alberta greenhouse gas emission abatement strategy. Given that the strategy is centered on deployment of CCS technologies, we analyze the effects of the declines in natural gas price on CCS deployment in the electricity sector. We use the CIMS simulation model to simulate various policy scenarios under high and low natural gas price assumptions. Comparison of the results shows that CCS market penetration in the electricity sector is very minimal in the low natural gas price scenario even when a 50% cost subsidy is applied. Accordingly, there is little gain from subsidizing CCS given the "shale gas revolution." We provide a few concluding remarks in Chapter 5.

    Since the 1970s, Canada has formulated various strategy measures to accelerate the development of energy efficiency systems and renewable energy technologies and has made significant progress. ''From 1990 to 2003, Canada's energy efficiency improved by an estimated 13%, or 883.3 petajoules, saving Canadians almost $13.4 billion in 2003 alone and reducing annual greenhouse gas emissions by 52.3 megatonnes''. In 2000, about 17% of Canadian primary energy supply came from renewable sources (with hydroelectric, combustible renewables and waste). Canada is a leader in devising and implementing energy options for sustainable development. However, the nation still has great scope for furthering energy efficiency and more use of renewable energy. Canada has a higher aggregate intensity - absolute energy use per capita or per unit of GDP - than most International Energy Agency (IEA) countries, ranking second and fourth, respectively. In 2000, Canada used only a small amount of renewable energy (without hydroelectric, combustible renewables and waste), accounting for 1.3% of its primary energy supply. Canada has made little use of wind power compared to other industrialized countries. By June 2004, Canada's installed capacity was 341 megawatts (MW), compared to 13,407 MW installed by late 2003 in Germany, the country with the largest installed capacity. Canada's current small-scale hydroelectric capacity is about 2000 MW. Canada also has a few grid-connected wood-waste-fired power plants operational or under construction, with a maximum capacity of 60 MW. By 1999, Canada was generating 85.3 MW of electricity from captured municipal landfill gas. It is also worth noting that solar power is now finding niche applications in Canada, despite the fact that its cost remains relatively high (although falling). Canada is a signatory to the Kyoto Protocol. It has committed to reducing its emissions to 6% below 1990 levels by 2008-2012. But Canada

  13. Safety precautions in atomic pile control (1962)

    International Nuclear Information System (INIS)

    We have been led to study the problem of safety in atomic pile control as a result of our participation on the one hand in the planning of C.E.A. atomic piles, and on the other hand in the pile safety sub omission considering atomic pile safety of operational or planned C.E.A. piles. We have thus had to consider the wishes occurring in piles during their operation and also their behaviour in the dynamic state The present work deals mainly with the importance of intrinsic safety devices, with the influence of reactivity variations on the power fluctuations during accidental operation, and with the development of robust and reliable safety appliances. The starting p accident has been especially studied both for low-flux piles where a compromise is necessary between the response time of the safety appliances and the statistical fluctuations and for high lux piles where xenon poisoning has an effect on the lower limit of the velocity of reactivity liberation. The desirability has been stressed of automation as a safety factor in atomic pile control. The details required for an understanding of the diagrams of the apparatus are given. (author)

    Salasnich, Luca; Toigo, Flavio

    2016-06-01

    We analyze the divergent zero-point energy of a dilute and ultracold gas of atoms in D spatial dimensions. For bosonic atoms we explicitly show how to regularize this divergent contribution, which appears in the Gaussian fluctuations of the functional integration, by using three different regularization approaches: dimensional regularization, momentum-cutoff regularization and convergence-factor regularization. In the case of the ideal Bose gas the divergent zero-point fluctuations are completely removed, while in the case of the interacting Bose gas these zero-point fluctuations give rise to a finite correction to the equation of state. The final convergent equation of state is independent of the regularization procedure but depends on the dimensionality of the system and the two-dimensional case is highly nontrivial. We also discuss very recent theoretical results on the divergent zero-point energy of the D-dimensional superfluid Fermi gas in the BCS-BEC crossover. In this case the zero-point energy is due to both fermionic single-particle excitations and bosonic collective excitations, and its regularization gives remarkable analytical results in the BEC regime of composite bosons. We compare the beyond-mean-field equations of state of both bosons and fermions with relevant experimental data on dilute and ultracold atoms quantitatively confirming the contribution of zero-point-energy quantum fluctuations to the thermodynamics of ultracold atoms at very low temperatures.

    Full Text Available Abstract For more than two decades, the International Narcotic Control Board (INCB has tried to stop harm reduction and its HIV prevention programs. This posture is based on a fundamental misunderstanding of their responsibilities and of drug addiction itself – i.e. as a public health and clinical care matter made criminal by decree. A recent focal point for the Board's action has been rejecting the use of supervised injection facilities to reduce morbidity and mortality of drug injectors. They single out individual countries and attempt to bully them into rejecting such programs under the banner of the United Nations (falsely and in the name of international treaties. Their unrelenting and unjustified badgering of signatories to the international treaties that established the INCB is not only unjustified; it is an affront to one of the core purposes of the Board itself: to ensure adequate medical supplies and safe use of controlled substances. The INCB's ill-conceived obsession with intravenousaddiction as a crime flies in the face of the medical view and policies of the World Health Organization and the universally endorsed principles of the General Assembly of the United Nations. The latest target of the INCB is North America's only supervised injection facility, Insite, located in the inner city of Vancouver, Canada. Using the power of their office to meddle in matters of public health for individual nations is without medical, scientific or legal justification. But, most importantly, it is a matter of lifeand death for these most marginalized of citizens. The empirical evidence remains that a significant portion of the continued growth of the AIDS pandemic is due to injecting drug use, and the INCB's intrusion will inevitably result in additional deaths due to preventable HIV infections and drug overdoses. So we are very pleased to call to our readers' attention to a recent report produced by the Canadian HIV/AIDS Legal Network and the

  11. Probing Dark Energy with Atom Interferometry

    Burrage, Clare; Hinds, E A

    2015-01-01

    Theories of dark energy require a screening mechanism to explain why the associated scalar fields do not mediate observable long range fifth forces. The archetype of this is the chameleon field. Here we show that individual atoms are too small to screen the chameleon field inside a large high-vacuum chamber, and therefore can detect the field with high sensitivity. We derive new limits on the chameleon parameters from existing experiments, and show that most of the remaining chameleon parameter space is readily accessible using atom interferometry.

    On-board real time flight control is studied in order to develop algorithms which are simple enough to be used in practice, for a variety of missions involving three dimensional flight. The intercept mission in symmetric flight is emphasized. Extensive computation is required on the ground prior to the mission but the ensuing on-board exploitation is extremely simple. The scheme takes advantage of the boundary layer structure common in singular perturbations, arising with the multiple time scales appropriate to aircraft dynamics. Energy modelling of aircraft is used as the starting point for the analysis. In the symmetric case, a nominal path is generated which fairs into the dash or cruise state. Feedback coefficients are found as functions of the remaining energy to go (dash energy less current energy) along the nominal path.

  17. Proposed quantitative approach to safety for nuclear power plants in Canada

    International Nuclear Information System (INIS)

    A set of quantitative risk and frequency limits plus required processes is proposed to help ensure that a nuclear power plant in Canada meets the qualitative safety objectives defined in ACNS-2 and in IAEA 75-INSAG-3. As emphasized in this report, risks and hence doses are to be reduced below the limits using ALARA (As Low as Reasonably Achievable, economic and social factors being taken into account) or VIA (value-impact analysis) processes unless, in general, calculated risks and hence doses are below recommended de minimis levels. An updated version of ACNS-4, which will be issued as ACNS-21, will incorporate a statement of these limits and objectives as well as assessment criteria and procedures that will facilitate their application. The quantitative approach proposed here is consistent with a growing consensus on the need for, and the elements of, a quantitative approach to risk management of all major activities in an advanced industrial society. The ACNS recommends that the Atomic Energy Control Board adopt the proposed approach as a rational and coherent basis for nuclear power plant safety policy and requirements in Canada.

  1. Atom-Role-Based Access Control Model

    Cai, Weihong; Huang, Richeng; Hou, Xiaoli; Wei, Gang; Xiao, Shui; Chen, Yindong

    Role-based access control (RBAC) model has been widely recognized as an efficient access control model and becomes a hot research topic of information security at present. However, in the large-scale enterprise application environments, the traditional RBAC model based on the role hierarchy has the following deficiencies: Firstly, it is unable to reflect the role relationships in complicated cases effectively, which does not accord with practical applications. Secondly, the senior role unconditionally inherits all permissions of the junior role, thus if a user is under the supervisor role, he may accumulate all permissions, and this easily causes the abuse of permission and violates the least privilege principle, which is one of the main security principles. To deal with these problems, we, after analyzing permission types and role relationships, proposed the concept of atom role and built an atom-role-based access control model, called ATRBAC, by dividing the permission set of each regular role based on inheritance path relationships. Through the application-specific analysis, this model can well meet the access control requirements.

  3. Using atom interferometry to detect dark energy

    Burrage, Clare; Copeland, Edmund J.

    2016-04-01

    We review the tantalising prospect that the first evidence for the dark energy driving the observed acceleration of the universe on giga-parsec scales may be found through metre scale laboratory-based atom interferometry experiments. To do that, we first introduce the idea that scalar fields could be responsible for dark energy and show that in order to be compatible with fifth force constraints, these fields must have a screening mechanism which hides their effects from us within the solar system. Particular emphasis is placed on one such screening mechanism known as the chameleon effect where the field's mass becomes dependent on the environment. The way the field behaves in the presence of a spherical source is determined and we then go on to show how in the presence of the kind of high vacuum associated with atom interferometry experiments, and when the test particle is an atom, it is possible to use the associated interference pattern to place constraints on the acceleration due to the fifth force of the chameleon field - this has already been used to rule out large regions of the chameleon parameter space and maybe one day will be able to detect the force due to the dark energy field in the laboratory.

  4. BP Canada Energy Company : climate change action plan update 1999-2000

    International Nuclear Information System (INIS)

    An aggressive, world-wide target for a 10 per cent reduction of greenhouse gas emissions was set by BP p.l.c. and BP Canada Energy Company has supported this endeavour. Six major areas have been identified as offering potential solutions to the problem of climate change: the control of greenhouse gases, the conservation of energy, the introduction of new technologies, the promotion of flexible market instruments, the participation in the policy process, and an investment in research. This document reviewed the efforts expanded to date in those areas. It was noted that a deliberate shift was made by BP leadership from oil to natural gas production, releasing much less carbon dioxide in the atmosphere when burned. A brief overview of the operations of BP Canada Energy Company was provided in chapter 1, followed by the philosophy concerning greenhouse gases in chapter 2. In chapter 3, the topic of BP's global emissions trading system was discussed. The current and projected greenhouse gas emissions were looked at in chapter 4, while chapter 5 dealt with setting global targets, with specific emphasis on Canadian targets. In chapter 6 , the emphasis was placed on BP's emission reduction initiatives. In chapter 7, the question of raising awareness was examined. 7 tabs., 7 figs

    Atomic interferometry can be used to probe dark energy models coupled to matter. We consider the constraints coming from recent experimental results on models generalising the inverse power law chameleons such as $f(R)$ gravity in the large curvature regime, the environmentally dependent dilaton and symmetrons. Using the tomographic description of these models, we find that only symmetrons with masses smaller than the dark energy scale can be efficiently tested. In this regime, the resulting constraints complement the bounds from the E\\"otwash experiment and exclude small values of the symmetron self-coupling.

    Canada is blessed with a variety of natural resources in significant quantities; the country has important reserves of oil, natural gas, uranium and coal as well as a significant potential for renewable energies such as hydroelectricity, biofuels, wind and tidal power. This abundance of natural resources combined with a strategic location from which to access both the United States and Chinese markets play a significant part in contributing to Canada's prosperity. The aim of this paper is to show that Canada can be an energy and resource powerhouse and a leader in energy and environmental innovation. The Canadian Council of Chief Executives believes that government, industry and Canadians need to pull in the same direction in order to achieve it. This document points out that Canada can have an important role in the development of new energy and environmental technologies and 5 recommendations are made on how to achieve this goal.

  11. Landfill gas management in Canada

    International Nuclear Information System (INIS)

    Landfill gas produced from solid waste landfills is one of the most significant sources of anthropogenic methane in Canada. Methane, a potent greenhouse gas, is 24.5 times more powerful than carbon dioxide by weight in terms of global climate change. Landfill gas recovery plays an important role in Canada's commitment to stabilize greenhouse gas emissions at 1990 levels by the year 2000 under the United Nations Framework Convention on Climate Change. Landfill gas is a potentially harmful emission that can be converted into a reliable environmentally-sustainable energy source used to generate electricity, fuel industries and heat buildings. The recovery and utilization of landfill gas is a win-win situation which makes good sense from local, regional and global perspectives. It provides the benefits of (1) reducing the release of greenhouse gases that contribute to global warming; (2) limiting odors; (3) controlling damage to vegetation; (4) reducing risks from explosions, fires and asphyxiation; (5) converting a harmful emission into a reliable energy source; and (6) creating a potential source of revenue and profit. Canadian landfills generate about 1 million tons of methane every year; the equivalent energy of 9 million barrels of oil (eight oil super tankers), or enough energy to meet the annual heating needs of more than half a million Canadian homes. Currently, twenty-seven facilities recover and combust roughly 25% of the methane generated by Canadian landfills producing about 3.2 PJ (1015 Joules) of energy including 80 MW of electricity and direct fuel for nearby facilities (e.g., cement plants, gypsum board manufacturers, recycling facilities, greenhouses). This paper reviews landfill gas characteristics; environmental, health and safety impacts; landfill gas management in Canada; the costs of landfill gas recovery and utilization systems; and on-going projects on landfill gas utilization and flaring

    International Nuclear Information System (INIS)

    Countries with large stock of fissile material and producing large quantity of nuclear pure 235U and 239Pu are able to allocate part of the stock to non military research. For countries with low stock of fissile material, all the stock is allocated to military research. An economical and technical solution has to be find to dedicate a part of fissile material to non military research and develop the atomic energy industry. It stated the industrial and economical problems and in particular the choice between the use of enriched fuel with high refining cost or depleted fuel with low production cost. It discusses of four possible utilizations of the natural resources: reactors functioning with pure fissile material (235U or 239Pu) or concentrated material (235U mixed with small quantities of 238U after an incomplete isotopic separation), breeder reactors functioning with enriched material mixed with 238U or Thorium placed in an appropriate spatial distribution to allow neutrons beam to activate 238U or Thorium with the regeneration of fissile material in 239Pu, reactors using natural uranium or low enriched uranium can also produce Plutonium with less efficiency than breeder reactors and the last solution being the use of natural uranium with the only scope of energy production and no production of secondary fissile material. The first class using pure fissile material has a low energy efficiency and is used only by large fissile material stock countries to accumulate energy in small size fuel for nuclear engines researches for submarines and warships. The advantage of the second class of reactors, breeder reactors, is that they produce energy and plutonium. Two type of breeder reactor are considered: breeder reactor using pure fissile material and 238U or breeder reactor using the promising mixture of pure fissile material and Thorium. Different projects are in phase of development in United States, England and Scotland. The third class of reactor using natural

  18. Atom-interferometry constraints on dark energy

    CERN Document Server

    Hamilton, Paul; Haslinger, Philipp; Simmons, Quinn; Müller, Holger; Khoury, Justin

    2015-01-01

    If dark energy---which drives the accelerated expansion of the universe---consists of a new light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. There has, however, been much theoretical progress in developing theories with screening mechanisms, which can evade detection by suppressing forces in regions of high density, such as the laboratory. One prominent example is the chameleon field. We reduce the effect of this screening mechanism by probing the chameleon with individual atoms rather than bulk matter. Using a cesium matter-wave interferometer near a spherical mass in an ultra-high vacuum chamber, we constrain a wide class of dynamical dark energy theories. Our experiment excludes a range of chameleon theories that reproduce the observed cosmic acceleration.

  19. Constitutionality of the Atomic Energy Act

The Federal Constitutional Court declared in its decree of 8 August 1978 the peaceful uses of nuclear energy (Paragraph 7 sub-section 1 and 2 Atomic Energy Act) in NPPs of the so-called fast breeder type as constitutional for the time being. The excellent simplicity of the explanations, namely about the anavoidability and social adequancy of the so-called residual risk in a highly technical society and about the determining influence of practical ratio as a measure for the estimation of the residual risk which must be born by all citizens, creates a good clarification on the level of constitutional law. However, it remains, to be seen whether the decree can give the administrative courts any orientation help in the future and whether it will lead to an improved legal protection of all participants and a more effective handling of administrative processes.

This initiative led to the development of an action plan by joint Canada-U.S. working groups that comprise activities in three defined areas: the development of clean energy technology, the construction of a more efficient energy grid, and the expansion of research and development (R&D). The objective is to improve available modes of environmentally responsible energy production, minimize waste in energy transportation and delivery, and set up new alternatives. This document is a study used as a source of information by the working group. It will allow a better understanding of the scientific production, give an overview of the various collaboration and trends around the world in the field of clean energy R&D and in three subfields of interest: future generation biofuels, clean engines/vehicles and energy efficiency homes and buildings. This scientometric study shows that, in clean energy R&D, the U.S. and Canada are among the 15 leading countries. In clean energy R&D and in the three subfields, Canada's strongest affinities are generally with the U.S., Turkey and China. Sweden and Turkey stand out as having levels of impact and specialization that are above the world level. Clean energy R&D is examined as a whole before focusing on scientific activity in future generation biofuels, clean energy vehicles and green buildings. An insight of the relative strengths and weaknesses of Canada and the U.S. in these areas appears within the presented data. Leading Canadian and U.S. research institutions are also considered for a better understanding of their involvement in these fields and to determine those that were the most active in terms of Canada/U.S. cross-border collaborations. 19 tabs., 15 figs.

  3. Atomic Structure of Benzene Which Accounts for Resonance Energy

    OpenAIRE

    Heyrovska, Raji

    2008-01-01

    Benzene is a hexagonal molecule of six carbon atoms, each of which is bound to six hydrogen atoms. The equality of all six CC bond lengths, despite the alternating double and single bonds, and the surplus (resonance) energy, led to the suggestion of two resonanting structures. Here, the new atomic structure shows that the bond length equality is due to three carbon atoms with double bond radii bound to three other carbon atoms with resonance bond radii (as in graphene). Consequently, there ar...

  4. Replacing coal power in Canada with renewable energy. Paper no. IGEC-1-114

    International Nuclear Information System (INIS)

    There are those who believe that global warming is a natural phenomenon that does not require any immediate action. However, current evidence indicates that record setting CO2, CH4 and N2O levels have contributed to a record number of asthma related illnesses, especially amongst children. Furthermore, the number and severity of natural disasters has risen dramatically over the last 50 years while the rate of geophysical disasters like earthquakes has remained constant. Currently, just under 30% of Canada's energy production comes from non-renewable thermal sources: coal, oil, and natural gas. As an attempt to reduce CO2 levels, certain Canadian provinces have stated intentions to increase the proportion of energy produced by natural gas. However, at current production rates, Canada will have exhausted its natural gas reserves in less than nine years. At present, coal represents 19% of Canada's energy production but emits 80% of the sectors green house gases. Green house gas emission levels can be reduced by 14% if coal power is replaced with a cleaner energy source. Due to the depleting natural gas reserves, renewable energy sources should be strongly considered as an economically feasible replacement of coal. This possibility will be discussed in the paper. It was found that through wind, geothermal, tidal and biomass energy sources, coal power plants can be completely eliminated from Canada. The additional cost to Canada for such an endeavour would be $3.5 billion CAN. (author)

  5. Quickening nature's pulse: atomic agriculture at the International Atomic Energy Agency.

    2015-01-01

    Mutation breeders in the 1960s seemed poised to use atomic energy to speed up mutation rates in plants in order to develop new crop varieties, for the benefit of all people. Although skepticism had slowed this work in the United States, the International Atomic Energy Agency (IAEA) nurtured the scientific field, its community of experts, and an imagined version of the future that put humans in control of their destiny. The IAEA acted as a center of dissemination and support for experts and ideas even when they had fallen from favor elsewhere. Through the lens of the IAEA, plant breeding bore the appearance of a socially progressive, ultra-modern science destined to alleviate population pressures. Administrators at the IAEA also were desperate for success stories, hoping to highlight mutation plant breeding as a potential solution to the world's ills. The community of mutation plant breeders gained a lifeline from the consistent clarion call from the Vienna-based agency to use atomic energy to understand the natural world and quicken its pulse with radioisotopes.

  6. Evaluation Logic of Main Control Board Fire Risk

    International Nuclear Information System (INIS)

    The main control board (MCB) is defined as the collection of control panels inside the main control room (MCR) of a nuclear power plant (NPP). As the MCB has the control and instrumentation circuits of redundant trains for almost all plant systems, small fires within the control panels may be detrimental to the safe shutdown capability. A big fire affecting many panels in the MCB can cause a forced MCR abandonment of the operators as well as function failures or spurious operations of the control and instrumentation-related components. If the MCR cannot be habitable, a safe shutdown from outside the MCR can be achieved and maintained at an alternate shutdown panel electrically and physically independent from the MCR. Because the MCB consist of many electrical panels, it may have internal barriers between them to prevent a fire from spreading from its origin to neighboring locations. However, most MCBs of domestic NPPs do not have internal barriers within them. If the MCB cabinets are not separated by a double wall with an air gap, the fire propagation of an MCB panel fire cannot be ruled out. Recently, Joglar et al. proposed a new evaluation logic for the MCB panel fires and mentioned that an MCB fire can be divided into propagation and non-propagating fires for abandonment and non-abandonment fire scenarios. However, they did not present the details on the fire modeling approaches and probability formulas for the fire scenarios. In this paper, a decision tree for evaluating the risk of an MCB fire is proposed to systematically determine the fire scenarios in terms of the fire modeling approaches.

    The time-dependent multilevel approach (TDMA) and B-spline expansion technique are used to study the coherent population transfer between the quantum states of a potassium atom by a single frequency-chirped microwave pulse.The Rydberg potassium atom energy levels of n =6-15,l =0-5 states in zero field are calculated and the results are in good agreement with other theoretical values.The time evolutions of the population transfer of the six states from n =70 to n =75 in different microwave fields are obtained.The results show that the coherent control of the population transfer from the lower states to the higher ones can be accomplished by optimizing the microwave pulse parameters.

  9. Atomic Structure of Benzene Which Accounts for Resonance Energy

    2008-01-01

    Benzene is a hexagonal molecule of six carbon atoms, each of which is bound to six hydrogen atoms. The equality of all six CC bond lengths, despite the alternating double and single bonds, and the surplus (resonance) energy, led to the suggestion of two resonanting structures. Here, the new atomic structure shows that the bond length equality is due to three carbon atoms with double bond radii bound to three other carbon atoms with resonance bond radii (as in graphene). Consequently, there are two kinds of CH bonds of slightly different lengths. The bond energies account for the resonance energy.

  11. On-board near-optimal climb-dash energy management

    Science.gov (United States)

    Weston, A. R.; Cliff, E. M.; Kelley, H. J.

    1983-01-01

    On-board real time flight control is studied in order to develop algorithms which are simple enough to be used in practice, for a variety of missions involving three dimensional flight. The intercept mission in symmetric flight is emphasized. Extensive computation is required on the ground prior to the mission but the ensuing on-board exploitation is extremely simple. The scheme takes advantage of the boundary layer structure common in singular perturbations, arising with the multiple time scales appropriate to aircraft dynamics. Energy modelling of aircraft is used as the starting point for the analysis. In the symmetric case, a nominal path is generated which fairs into the dash or cruise state.

  14. Atomic coherence control on the entanglement of two atoms in two-photon processes

    Institute of Scientific and Technical Information of China (English)

    Hu Yao-Hua; Fang Mao-Fa; Wu Qin

    2007-01-01

    Considering two identical two-level atoms interacting with a single-mode thermal field through two-photon processes, this paper studies the atomic coherence control on the entanglement between two two-level atoms, and finds that the entanglement is greatly enhanced due to the initial atomic coherence. The results show that the entanglement can be manipulated by changing the initial parameters of the system, such as the superposition coefficients and the relative phases of the initial atomic coherent state and the mean photon number of the cavity field.

  18. Israel Atomic Energy Commission 1996 Annual Report

    International Nuclear Information System (INIS)

    Selecting the research efforts to be highlighted in the Israel Atomic Energy Commission's Annual Report from the large body and broad spectrum of ongoing work is not an easy task. The extensive bibliography of published results attached to the report attests to the scope of this difficulty. Of the many worthwhile projects, four were chosen to represent best the current trends in the continuing R and D program at the research centers of the Israel Atomic Energy Commission. One of these trends is the growing cooperation with private industry, in an attempt to gear our R and D programs to respond to market demands. Another feature, noted already several years ago, is the extensive collaboration of our scientists and engineers with colleagues at other institutions, in Israel and abroad. some of the work reported is part of evolving international industrial cooperation projects, illustrating both these trends. Following a trend common to many nuclear research centers around the world, a substantial part of our research effort is non-nuclear in nature. This is illustrated in the first article, which deals with advances in the application of non-linear optics in diverse fields of science and technology. These include state-of-the-art solid-state lasers, rapid modulation of light signals, development and generation of tunable sources of coherent light, optical data storage and the microscopic probing of biological and inorganic samples. The present work reports on a range of R and D, from the fundamentals of non-linear optical materials to proof-of-principle demonstrations of non-linear subwavelength resolution microscopy, to fabrication of prototype commercial tunable laser systems The second report considers the microstrain characteristics in some alloys using X-ray diffraction (XRD). The research utilizes XRD line broadening effects to study the characteristics of alloys from especially prepared surfaces. These characteristics include the homogeneity of alloying

  19. Atomic energy policy in fiscal year 1985

    International Nuclear Information System (INIS)

    The international demand and supply of petroleum advance in relaxed condition at present, but tend to get stringent in long term. Nuclear power is the most promising substitute energy for petroleum, and in Japan, 28 nuclear power plants with 20.56 million kW output are in operation, generating 20.4% of the total generated power in 1983. According to the perspective of long term power supply, the installed capacity of nuclear power plants will reach 62 million kW and 27% of the total installed capacity by 2000. It is important to positively deal with the industrialization of nuclear fuel cycle, the upgrading of nuclear power generation, the development of the reactors of new types and so on, preparing for the age that nuclear power generation will become the center of power supply. The atomic energy policy of the Ministry of International Trade and Industry in fiscal year 1985 is reflected to the budget, financial investment and funding and other measures based on the above viewpoint. The outline of the budget and financial investment and funding for fiscal year 1985 is explained. The points are the promotion of industrialization of nuclear fuel cycle, the promotion of nuclear power generation and the promotion of understanding and cooperation of nation on the location of electric power sources.

  5. Analysis of 44 Cases before the Landlord and Tenant Board Involving Bed Bug Infestations in Ontario, Canada: Focus on Adjudicator Decisions Based on Entomological/Pest Management Evidence and Accountability under the Residential Tenancy Act and Other Applicable Legislation

    Directory of Open Access Journals (Sweden)

    Sam Bryks

    2011-07-01

    Full Text Available The resurgence of bed bugs in major urban centres in North America has resulted in conflict between landlords and tenants. This is commonly focused on attribution of blame for source of infestation, on responsibility, on costs for preparation, treatment and losses, and for compensation as rent abatement and/or alternative temporary housing. In Ontario, Canada, these issues are often decided by adjudicators at the Landlord and Tenant Board hearing claims, counter-claims and defense by legal representation (lawyers and paralegals as well as through mediation. Evidence in these hearings may include photographs, invoices for costs as well as testimony by tenants, landlords and “expert witnesses” who are most often pest control firms representing their landlord clients. A total of 44 Landlord and Tenant Board adjudicated cases available online were analyzed. The analysis included elements of the decisions such as adjudicator, claimant (landlord or tenant, basis of claim, review of evidence, amount of claim, amount awarded, and evaluation of the quality of the evidence. The results of the analysis of these findings are discussed. Recommendations for improvement of adjudicator decisions on the basis of knowledge of bed bug biology and Integrated Pest Management best practices are presented as well as the importance of education of tenants and landlords to a process of mutual trust, support and accountability.

    2006-01-01

    We monitored populations of Canada thistle biocontrol agents Cassida rubiginosa, Ceutorhynchus litura, Larinus (= Hadroplantus) planus, Urophora cardui, Orellia (= Terellia) ruficauda, and Rhinocyllus conicus on Canada thistle (Cirsium arvense) at two national wildlife refuges in South Dakota from 1999 through 2003. C. litura, U. cardui, O. ruficauda, and R. conicus were present on both refuges. Agent populations were low except for C. litura, which was present in up to 90% of stems in some plots. C. litura infestation did not reduce thistle flowering, stem length, or over-winter survival. There was no change in thistle stem numbers over the study period and no difference in stem numbers in areas of high C. litura populations compared to areas of low C. litura populations. Our results suggest that insect biological control agents are inadequate for reduction of Canada thistle in southern South Dakota.

    Science.gov (United States)

    Bariani, F.; Otterbach, J.; Tan, Huatang; Meystre, P.

    2014-01-01

    We investigate a hybrid electromechanical system consisting of a pair of charged macroscopic mechanical oscillators coupled to a small ensemble of Rydberg atoms. The resonant dipole-dipole coupling between an internal atomic Rydberg transition and the mechanics allows cooling to its motional ground state with a single atom despite the considerable mass imbalance between the two subsystems. We show that the rich electronic spectrum of Rydberg atoms, combined with their high degree of optical control, paves the way towards implementing various quantum-control protocols for the mechanical oscillators.

  13. Canada's power play : the case for a Canadian energy strategy for a carbon-constrained world

    International Nuclear Information System (INIS)

    This paper presented the results of a series of energy sector consultations conducted across western Canada to determine expert opinions related to the subject of energy policy in Canada. The consultations indicated that many sector experts and stakeholders feel that climate change must be addressed when designing an energy policy for Canada, and that a fair balance must be obtained between the need for economic and environmental sustainability. The economy should not be compromised by action on climate change, and regional differences should be considered. Results of the study suggested that a Canadian energy strategy should coordinate federal, provincial, territorial, and municipal energy policy initiatives. Energy production targets for a range of renewable and non-renewable energy sources should be established. The strategy should inform and be compatible with a national climate change strategy, and move beyond regulation and singular initiatives such as carbon capture and storage. The strategy should stress energy conservation, send appropriate price signals as financial incentives for change, and recognize the need for public investment in research and technology. The document stated that an effective energy strategy may take many years to establish.

  14. The regulation of radioactive waste management in Canada

    International Nuclear Information System (INIS)

    Radioactive waste management facilities are subject to the Atomic Energy Control Regulations under jurisdiction of the Atomic Energy Control Board. Before such a facility can be constructed and permitted to operate, the applicant must obtain from the AECB in turn, site approval, a construction approval, and an operating licence, different considerations (e.g. geological, security) being given priority at each stage. Operating licences are normally valid for one year only, their renewal being dependent on observance, by the applicant, of the procedures and conditions laid down by the Board. Licensing document No.23 offers guidance on the requirements involved both generally and in relation to specific methods of waste storage and disposal. A copy of this document is attached to the present paper. (NEA)

  15. Impact of disinfecting nesting boards on chalkbrood control in the alfalfa leafcutting bee.

    Science.gov (United States)

    James, R R

    2005-08-01

    The alfalfa leafcutting bee, Megachile rotundata (F.), is a solitary, cavity-nesting bee that has been managed in large numbers to pollinate alfalfa, Medicago spp., seed crops since the 1960s. Propagation of these bees from 1 yr to the next has been seriously hampered by chalkbrood, a larval disease caused by the fungus Ascosphaera aggregata Skou. In the United States, attempts to control the disease have been fairly unsuccessful, but include removing nests from the nesting boards and then disinfecting the boards with heat treatments or a fumigant. The problem is that many boards are made of polystyrene (so heat cannot be used), and very few fumigants are registered for this use. In this study, ozone was tested as a fumigant and compared with heat treatments and methyl bromide fumigation. Ozone was found to be inadequate for killing A. aggregata spores and for reducing chalkbrood levels in the field. Methyl bromide and heat treatments did greatly reduce spore viability in the boards, but did not reduce chalkbrood levels in the field. Surprisingly, larvae in new nesting boards (boards free of contamination) and chalkbrood infection levels were similar to those from nests in contaminated, used boards. Disinfecting nesting boards may be necessary for controlling chalkbrood, but the results reported here indicate that it is not sufficient in and of itself. Some other source of spores was present in the field that was greater than the effect of contamination from the boards, but the source still needs to be determined. PMID:16156558

    2014-11-12

    The local atomic bonding of carbon atoms around the edge of graphene is examined by aberration-corrected scanning transmission electron microscopy (STEM) combined with electron energy loss spectroscopy (EELS). High-resolution 2D maps of the EELS combined with atomic resolution annular dark field STEM images enables correlations between the carbon K-edge EELS and the atomic structure. We show that energy states of graphene edges vary across individual atoms along the edge according to their specific C-C bonding, as well as perpendicular to the edge. Unique spectroscopic peaks from the EELS are assigned to specific C atoms, which enables unambiguous spectroscopic fingerprint identification for the atomic structure of graphene edges with unprecedented detail.

    1998-01-01

    The basic research on the control of atoms using the coherent interaction, such as the development of the generator of the thermal atomic beam with high directionality, the photodeflection of atomic beam and the coherent excitation of atoms, has been performed. Yb atomic beam with small divergence was generated and the deflection mechanism of the atomic beam was studied by using a broad band dye laser and a narrow band laser. It has been proved that the single mode dye laser with narrow bandwidth was suitable for deflection of atoms but the frequency locking system was indispensable. And the apparatus for intermodulated optogalvanic (IMOG) experiment was developed and the high resolution optogalvanic spectroscopy was studied for laser frequency stabilization.

    Energy status was analyzed in glass eels captured during two early waves of arrival at the mouths of the Mersey River, Nova Scotia, Canada (MR), and Grande-Rivière-Blanche, Québec, Canada (GRB), and according to their salinity preference (freshwater, brackish, or saltwater). Glass eels captured in the GRB estuary were larger, more pigmented, and exhibited higher whole-body glycogen, phospholipid, and sterol and wax ester contents. Those from MR had a higher condition index and a higher whole-body triacylglycerol content, suggesting different patterns of storage and/or use of energy reserves. Within a river, a delay of two weeks in estuarine arrival was characterized by significantly lower energy reserves. No differences in energy storage were observed according to salinity preference. Thus, the results revealed the occurrence of different energy storage strategies according to glass eel migration distance and duration, but not according to salinity preference.

  1. Operation and profits of energy boards. A study of the basis of municipal business activities and the equitableness of the profits of municipal energy boards

    International Nuclear Information System (INIS)

    The objective of the empirical part of the study (Chapter 6) is to evaluate the equitableness of profits on capital invested of the 16 municipal energy boards selected for this study and, at the same time, to create a general evaluation basis for equity decisions made by the authorities case by case. In this part of the study, answers are sought for the following questions: (1) how has the economic situation of the energy boards studied been recently developing based on various economic parameters? (2) have there been differences in the returns and profitability of energy boards operating as public utilities or energy boards operating in company form? (3) what kind of a price level the energy boards studied have maintained in relation to the national averages of this field? (4) is a city in a weaker economic position more tempted to require higher profits on capital invested than a city with a sound economic basis? (5) how high profits on capital invested can be considered reasonable for the whole energy board and particularly for a network business holding a monopoly? The structure of the study is as follows. Chapter 2 contains a brief description of the energy boards selected for this study and of the economic situation of the cities owning them. The theoretical part of the study is included in Chapter 3 'Municipal Self-Government and Business'. It analyses rather deeply the terminology of the municipal business, norm basis, steering of actions, restructuring of companies into business profit centres and privatisation, as well as application of the Act on Restrictions on Competition from the standpoint of a municipal self-government. Chapter 4 deals with the establishment of energy board activity, the legal basis and the criteria for pricing electricity, network services and district heat. Chapter 5 examines the Act on Restrictions on Competition as a regulator of the energy board activities. After this, there are the presentations of the research results of the

  2. Young students's opinion about atomic energy

    International Nuclear Information System (INIS)

    The present research work was performed in answer to a requirement that the CNEA-RC made to students of the Public and Institutional Relations Degree of the UES21, as a part of activities carried out in the framework of the Academic Cooperation Agreement between both institutions. In this case the students had to attend the Professional Practical course during the first semester of 2006, which included a short period in some company or organization. The Degree of Knowledge and the Opinion of the students from the Cycle of Specialization of the Province of Cordoba Educational System (ages between 15 and 17 years old), on the activities that are made in the site of CNEA-RC and DIOXITEK SA at Alta Cordoba neighborhood in Cordoba city has been analyzed. The same aspects were analyzed for Dioxitek's activities (equipment, raw materials, risk performance, etc.). Although the activities made at CNEA-RC involved during 2005/6 about 4000 students, due to the short time available for the practical part only the data of two schools located near the facilities were processed. Three aspects of the space conformed between the public and the general opinion were analyzed: the customs, the stereotypes and the attitudes of the people. These aspects were taken as the characteristics to describe to the opinions, their direction and intensity. The analysis was based on an exploratory investigation of type, characterized by its flexibility. The field work was of quantitative character. The surveys were structured with closed questions (categories of answers delimited previously on which the students must answer). For its design we used diverse sources of intelligence, such as pages of Internet, pamphlets, magazines, annual balances of the organizations, etc. The main results were the following: 1) The greater percentage of students declared to have little information on Atomic Energy. Only 4% declared to have abundant knowledge on the subject. 2) A 38% of the students indicated that

    2006-07-01

    This conference was attended by experts from across Canada specializing in decentralized energy (DE) research, sales, marketing and technical design. The presentations outlined provincial and territorial perspectives on DE and its role in energy security. DE refers to the production, management and storage of power, irrespective of generator size, fuel or technology that is located close to a customer's load and point of consumption. DE complements traditional, centralized, large-scale power generation and can be either grid-connected or off-grid. The barriers to widespread use of DE were also discussed. Representatives from provinces and territories reported on experiences with DE applications and the effectiveness of some of Canada's emerging energy policies. Topical issues included DE markets; business opportunities; overcoming industry challenges; leadership in industry; and, existing technology markets. The need for technology diversification for developing a sustainable energy infrastructure was emphasized along with the need for updating policies to meet changing energy demands. DE offers advantages in terms of economics, security, transmission and distribution, fuel use, emissions reductions and power quality. Examples of DE technologies include gas fired cogeneration, biomass combustion, small-scale hydro development, reciprocating engine cogeneration and, fuel cells. The conference featured 25 presentations, of which 4 have been catalogued separately for inclusion in this database. refs., tabs., figs.

    2003-01-01

    Suicide is a multiply determined behavior, calling for diverse prevention efforts. Gun control has been proposed as an important component of society's response, and an opportunity for studying the effects of legislative gun control laws on suicide rates was provided by Canada's Criminal Law Amendment Act of 1977 (Bill C-51). This article reviews previous studies of the impact of this act on the total population of Canada and subpopulations by age and gender and, in addition, presents the results of 2 new studies: a different method of analysis, an interrupted time-series analysis, and the results of a multiple regression analysis that controls for some social variables. It appears that Bill C-51 may have had an impact on suicide rates, even after controls for social variables. PMID:12675070

  11. Atomic energy and science disclosure in Cordoba

    International Nuclear Information System (INIS)

    In September 2009, considering the existing interest in public communication of scientific activities that are developed locally, a group of researchers and communicators from Córdoba, decided to form the Network of Outreach of Córdoba. Its stated objectives of the Constitutive Act are presented in this paper along with the main activities undertaken to date and plans for the future. Since that time, the Management of Institutional Relations of the CNEA in Córdoba became involved in public circulation of scientific knowledge, in what has proven to be a framework that ensures an adequate level of debate to present nuclear national activities. This will involve collaborative efforts with professional institutions involved in research, teaching and communicating science. The main objective was to encourage the transfer of knowledge to optimize available resources, improving the methodological approaches and generating creative products tailored to regional needs, in order to promote the democratization of science and nuclear technology. This paper consists of two parts. On the one hand describes the activities of the Network during the year 2011 shows results with particular emphasis on topics related to atomic energy, and secondly, shows the desirability of promoting such activities in the CNEA. Among the main actions considered, highlighting the institutional participation in the official Ministry of Science and Technology Fair participation in Science and Technology Provincial Cordoba 2011, issue of the radio program 'Green Light: Science and technology everyday life' by National Technological University Radio and a network of forty provincial stations, and active participation in the Course of Specialization in Public Communication of Science and Scientific Journalism, organized by the School of Information Sciences and the Faculty of Mathematics, Physics and Astronomy, National University of Cordoba, among others.

  12. When do energy-efficient appliances generate energy savings? Some evidence from Canada

    International Nuclear Information System (INIS)

    Improvements in the energy efficiency of household appliances have the potential to decrease residential energy use, but these reductions accrue gradually over time as newer appliances replace older models. SHEU-2003 data are used to examine appliance replacement patterns in Canada for refrigerators, freezers, dishwashers, clothes washers and clothes dryers. The data indicate that the ages at which appliances are replaced tend to be lowest for dishwashers and highest for freezers, with over 40% of freezers in use for more than 20 years before being retired. The life spans of Canadian appliances are compared to the underlying assumptions regarding appliance lifetimes used in models of residential energy demand. We find that Canadian appliance retirement patterns differ from those assumed in the previous literature. Socioeconomic factors related to appliance replacement are also examined. We find that replacement patterns can be sensitive to household characteristics such as income, providing evidence that there may be scope for targeted policies aimed at inducing earlier replacements of older household appliances with new energy-efficient models

    Justification for a board committee's existence is its ability to devote time to issues judged to be important by the full board. This seems to have happened. Multiple committees pursue more functions than the other committee structures. Boards lacking an FA/IC committee pursue significantly fewer functions than their counterparts with committees. Substantial respondent agreement exists on those functions most and least frequently pursued, those perceived to be most and least important, and those perceived to be most and least effectively undertaken. Distinctions between committee structures and the full board, noted in the previous paragraph, hold true with respect to the importance of functions. All board structures identified reviewing the budget and comparing it to actual results as important. Committee structures are generally more inclined to address functions related to the work of the independent auditor and the effectiveness of the hospital's system and controls than are full board structures. Functions related to the internal auditor are pursued least frequently by all FA/IC board structures. The following suggestions are made to help boards pay adequate attention to and obtain objective information about the financial affairs of their hospitals. Those boards that do not have some form of an FA/IC committee should consider starting one. Evidence shows chief financial officers have been a moving force in establishing and strengthening such committees. Boards having a joint or single committee structure should consider upgrading their structure to either a single committee or multiple committees respectively. The complexity of the healthcare environment requires that more FA/IC functions be addressed by the board. The board or its FA/IC committee(s) should meet with their independent CPA's, fiscal intermediary auditors, and internal auditors. Where the hospital lacks an internal audit function a study should be undertaken to determine the feasibility of

    Canada’s increasing reliance on the oil sands is not the best strategy for the economy or our environment. This report shows if the $1.3 billion in government subsidies, now given to the oil and gas sector, were instead invested in renewable energy and energy efficiency, Canada would create more jobs: 18,000 more. We also discuss in detail the economic risks of relying increasingly on the volatile oil market.

    Nearly 400 years after Galileo Galilei of Florence was arraigned and convicted of suspected heresy by the ten member Congregation of the Holy Office (Inquisition), the International Narcotic Control Board (INCB) is similarly inserting itself into matters pertaining to innovations in healthcare and the public health response to addiction throughout the world. Like that earlier Inquisition of 1633 that convicted Galileo of heresy for holding that the sun is the centre of the universe with the earth revolving around it (in contradiction to church doctrine of the time) the INCB and its thirteen-member panel, now rails against any evidence out of sync with the established doctrine of the war on drugs--particularly those innovations in public health called harm reduction. The latest healthcare and harm reduction practices to attract the ire of the INCB Inquisition are elements of Canada's most effective and innovative measures to minimize the harms of drugs in Vancouver--supervised injection facilities and, recently, the potential establishment of supervised inhalation rooms--along with the long established practice of providing safer mouthpieces for pulmonary inhalation in British Columbia. This is particularly significant as it comes in the midst of a crucial battle between municipal and provincial authorities in BC with the federal government in Ottawa, which seems determined to undermine all the most effective HR programs that are the result of years of steady local and governmental support in Vancouver and now threatens to derail all these programs and spread doubt about their usefulness despite the overwhelmingly positive findings of serous research.

    2013-01-01

    We introduce an easily implementable method for non-destructive measurements of ultracold atomic clouds based on dark field imaging of spatially resolved Faraday rotation. The dependence on laser detuning, atomic density and temperature is characterized in a detailed comparison with theory. Due to low destructiveness, the same cloud can be imaged up to 2000 times. The technique is applied to avoid the effect of shot-to-shot fluctuations in atom number calibration, to demonstrate single-run vector magnetic field imaging and single-run spatial imaging of the system's dynamic behavior. This paves the way towards quantum state engineering using feedback control of ultracold atoms.

    We study three-body recombination of Ba++Rb +Rb in the mK regime where a single 138Ba+ ion in a Paul trap is immersed into a cloud of ultracold 87Rb atoms. We measure the energy dependence of the three-body rate coefficient k3 and compare the results to the theoretical prediction, k3∝Ecol-3 /4, where Ecol is the collision energy. We find agreement if we assume that the nonthermal ion energy distribution is determined by at least two different micromotion induced energy scales. Furthermore, using classical trajectory calculations we predict how the median binding energy of the formed molecules scales with the collision energy. Our studies give new insights into the kinetics of an ion immersed in an ultracold atom cloud and yield important prospects for atom-ion experiments targeting the s -wave regime.

  1. Wind energy development as a tool of economic growth in Canada

    International Nuclear Information System (INIS)

    An overview is presented of the prospects for wind energy development in Canada and the economic benefits that could result from such development. The cost of installed capacity has dropped from $3,000 US/kW in the early 1980's to around $1,200/kW, and continues to decline. The cost of energy varies with the resource, but has typically declined from 14 cents/kW to better than 6 cents/kW. A 10 MW project is currently estimated to cost from $15-18 million Cdn, while a 30 MW project should cost ca $40 million. The wind industry could easily employ 5,000 people directly and 15,000 indirectly; shows substantial environmental benefits over conventional energy sources; and could provide 10% or 10,000 MW of Canada's required capacity. Barriers to wind energy development include utilities, which are uncomfortable with private generation, government policies which do not favour the development of alternative energy sources, and perceptual barriers. These perceptual barriers include: beliefs that wind energy is uneconomical; wind turbines do not work; power cannot be stored; reliability is poor; and that immense areas of turbines will be required. It is shown that these beliefs are either false or else are not relevant to Canada. 8 refs

    LHCb is one of the four experiments at the Large Hadron Collider. Before final reconstruction of the data in PC farms, high speed preprocessing is performed on a set of a few hundred custom electronics boards employing large modern field programmable gate array (FPGA) driven electronics. The local control of these boards is achieved via an embedded microcontroller which is connected to a large Local Area Network. After a brief introduction to the hardware we summarize the implementation of the entire layered software architecture for the readout boards and its integration into the Experiment Control System, which is built upon a common control framework based on an industrial SCADA system. Abstraction of different access modes and separation from the modeling of the components in the control system allow the reuse of various components on different hardware types. Each board has several hundreds of registers and memory blocks, so the optimization of write and read accesses is crucial for the s...

    @@ We propose a new lens scheme to focus cold atoms by using a controllable inhomogeneous magnetic field from a square current-carrying wire fabricated on a chip. The spatial distributions of the magnetic field are calculated, and the results show that the generated magnetic field is a two-dimensional (2D) quadrupole one and can be used to focus cold atoms or a cold atomic beam. The dynamic processes of cold atoms passing through our square wire layout and its focusing properties are studied by using Monte Carlo simulations. Our study shows that the atomic clouds can be focused effectively by our magnetic lens scheme, and the focal lengthof the atomic lens and its radius of focused spot can be continuously changed by adjusting the current in the wires.

    Study on one dimensional atom cooling and trapping process which is basic to the development of atom manipulation technology has been performed. A Zeeman slower has been designed and manufactured for efficient cooling of atoms. The speed of atoms finally achieved is as slow as 15 m/s with proper cooling conditions. By six circularly-polarized laser beams and quadrupole magnetic field, the atoms which have been slowed down by zeeman slower have been trapped in a small spatial region inside MOT. The higher the intensity of the slowing laser is the more is the number of atoms slowed and the maximum number of atoms trapped has been 10{sup 8}. The atoms of several tens of {mu}K degree have been trapped by controlling the intensity of trapping laser and intensity gradient of magnetic field. EIT phenomena caused by atomic coherent interaction has been studied for the development of atom optical elements.

It was noted that no market leader in ocean renewable energy has emerged, but that the industry has the potential for a more rapid adoption curve than the wind power industry. The integration of ocean renewable energy with offshore wind power production was discussed, as well as hydrogen production, remote electrification, and the production of potable water through desalination. Various incentives and international demonstration projects were reviewed and the goals of OREG were outlined. The forming of strategic alliances with other global organizations was discussed, as well as OREG's plans to contribute to the education of sources of capital to facilitate the commercialization of Canadian technologies. It was noted that pilot plants are planned with BC Hydro in 2007. Issues concerning environmental assessments were discussed. It was suggested that as the cost of traditional generation rises, investment in ocean energy development may reduce risks to investors and ratepayers. Issues concerning funding were examined and the OREG strategy and action plan was reviewed. Research and development themes were outlined. It was suggested that British Columbia's ocean energy regime provides a unique competitive advantage, as did natural winds for Denmark in the early 1980s. Pioneer sites and the creation of a supportive climate were discussed, as well as issues concerning regulators and grid connection investment. A supply chain was outlined and details of various companies involved in ocean energy development were presented. refs., tabs., figs

  12. The International Atomic Energy Agency Nuclear Security Education Strategies

    International Nuclear Information System (INIS)

    The threat of nuclear terrorism has not diminished. In response to the concerns of States, an international nuclear security framework has emerged through the establishment of a number of legally binding and non-binding international instruments which obligates or commits States to carry out a number of actions to protect against nuclear terrorism. In this context, the need for human resource development programmes in nuclear security was underscored at several International Atomic Energy Agency (IAEA) General Conferences and Board of Governors' Meetings. In the pursuit of this need, the IAEA provides a comprehensive nuclear security training programme to States on a regular basis, and has developed a concept that seeks to effectively pass ownership of nuclear security knowledge and skills to States through the establishment of a Nuclear Security Support Centre. In addition, the IAEA has developed a technical guidance titled IAEA Nuclear Security Series No. 12 - Educational Programme in Nuclear Security that consists of a model of a Master of Science (M.Sc.) and assists educational institutions to provide nuclear security education. The article sets out IAEA efforts in the area of nuclear security training and education, including the assistance to States for establishing a Nuclear Security Support Centre. It underlines the objective and content of the IAEA Nuclear Security Series No. 12, discusses different concepts on how to establish nuclear security at universities and, emphasizes on the IAEA efforts to assist educational and research institutions, and other stake holders to enhance global nuclear security by developing, sharing and promoting excellence in nuclear security education.

  14. Quantum Control nd Measurement of Spins in Cold Atomic Gases

    Science.gov (United States)

    Deutsch, Ivan

    2014-03-01

    Spins are natural carriers of quantum information given their long coherence time and our ability to precisely control and measure them with magneto-optical fields. Spins in cold atomic gases provide a pristine environment for such quantum control and measurement, and thus this system can act as a test-bed for the development of quantum simulators. I will discuss the progress my group has made in collaboration with Prof. Jessen, University of Arizona, to develop the toolbox for this test-bed. Through its interactions with rf and microwave magnetic fields, whose waveforms are designed through optimal control techniques, we can implement arbitrary unitary control on the internal hyperfine spins of cesium atoms, a 16 dimensional Hilbert space (isomorphic to 4 qubits). Control of the collective spin of the ensemble of many atoms is performed via the mutual coupling of the atomic ensemble to a mode of the electromagnetic field that acts as a quantum data bus for entangling atoms with one another. Internal spin control can be used to enhance the entangling power of the atom-photon interface. Finally, both projective and weak-continuous measurements can be performed to tomograhically reconstruct quantum states and processes.

    Increased blood pressure is a leading risk for premature death and disability. The causes of increased blood pressure are intuitive and well known. However, the fundamental basis and means for improving blood pressure control are highly integrated into our complex societal structure both inside and outside our health system and hence require a comprehensive discussion of the pathway forward. A group of Canadian experts was appointed by Hypertension Canada with funding from Public Health Agency of Canada and the Heart and Stroke Foundation of Canada, Canadian Institute for Health Research (HSFC-CIHR) Chair in Hypertension Prevention and Control to draft a discussion Framework for prevention and control of hypertension. The report includes an environmental scan of past and current activities, proposals for key indicators, and targets to be achieved by 2020, and what changes are likely to be required in Canada to achieve the proposed targets. The key targets are to reduce the prevalence of hypertension to 13% of adults and improve control to 78% of those with hypertension. Broad changes in government policy, research, and health services delivery are required for these changes to occur. The Hypertension Framework process is designed to have 3 phases. The first includes the experts' report which is summarized in this report. The second phase is to gather input and priorities for action from individuals and organizations for revision of the Framework. It is hoped the Framework will stimulate discussion and input for its full intended lifespan 2011-2020. The third phase is to work with individuals and organizations on the priorities set in phase 2.

    Quantum interference effects in inter-conversion between cold atoms and diatomic molecules are analysed. Within the framework of Fano's theory, continuum-bound anisotropic dressed state formalism of atom-molecule quantum dynamics is presented. This formalism is applicable in photo- and magneto-associative strong-coupling regimes. The significance of Fano effect in ultracold atom-molecule transitions is discussed. Quantum effects at low energy atom-molecule interface are important for exploring coherent phenomena in hither-to unexplored parameter regimes.

  18. Application of On-Board Evolutionary Algorithms to Underwater Robots to Optimally Replan Missions with Energy Constraints

    Full Text Available The objective is to show that on-board mission replanning for an AUV sensor coverage mission, based on available energy, enhances mission success. Autonomous underwater vehicles (AUVs are tasked to increasingly long deployments, consequently energy management issues are timely and relevant. Energy shortages can occur if the AUV unexpectedly travels against stronger currents, is not trimmed for the local water salinity has to get back on course, and so forth. An on-board knowledge-based agent, based on a genetic algorithm, was designed and validated to replan a near-optimal AUV survey mission. It considers the measured AUV energy consumption, attitudes, speed over ground, and known response to proposed missions through on-line dynamics and control predictions. For the case studied, the replanned mission improves the survey area coverage by a factor of 2 for an energy budget, that is, a factor of 2 less than planned. The contribution is a novel on-board cognitive capability in the form of an agent that monitors the energy and intelligently replans missions based on energy considerations with evolutionary methods.

    Experiments in atomic physics have exceptional sensitivity to small shifts in energy in an atom, ion, or bound particle. They are particularly well suited to search for unique low-energy signatures of new physics, including effects that could originate from the Planck scale. A number of recent experiments have used CPT and Lorentz violation as a candidate signal of new physics originating from the Planck scale. A discussion of these experiments and their theoretical implications is presented.

  9. Determination of Surface Exciton Energies by Velocity Resolved Atomic Desorption

    Energy Technology Data Exchange (ETDEWEB)

    Hess, Wayne P.; Joly, Alan G.; Beck, Kenneth M.; Sushko, Petr V.; Shluger, Alexander L.

    2004-08-20

    We have developed a new method for determining surface exciton band energies in alkali halides based on velocity-resolved atomic desorption (VRAD). Using this new method, we predict the surface exciton energies for K1, KBr, KC1, and NaC1 within +0.15 eV. Our data, combined with the available EELS data for alkali fluorides, demonstrate a universal linear correlation with the inverse inter-atomic distance in these materials. The results suggest that surface excitons exist in all alkali halides and their excitation energies can be predicted from the known bulk exciton energies and the obtained correlation plot.

  13. Atomic Physics in the Quest for Fusion Energy and ITER

    Energy Technology Data Exchange (ETDEWEB)

    2008-02-27

    The urgent quest for new energy sources has led developed countries, representing over half of the world population, to collaborate on demonstrating the scientific and technological feasibility of magnetic fusion through the construction and operation of ITER. Data on high-Z ions will be important in this quest. Tungsten plasma facing components have the necessary low erosion rates and low tritium retention but the high radiative efficiency of tungsten ions leads to stringent restrictions on the concentration of tungsten ions in the burning plasma. The influx of tungsten to the burning plasma will need to be diagnosed, understood and stringently controlled. Expanded knowledge of the atomic physics of neutral and ionized tungsten will be important to monitor impurity influxes and derive tungsten concentrations. Also, inert gases such as argon and xenon will be used to dissipate the heat flux flowing to the divertor. This article will summarize the spectroscopic diagnostics planned for ITER and outline areas where additional data is needed.

  14. Two atoms scattering at low and cold energies

    Indian Academy of Sciences (India)

    Hasi Ray

    2014-12-01

    A modified static-exchange model is developed to study the collision of an atom with another atom. It includes the effect of long-range dipole–dipole van der Waals interaction between two atoms in addition to the exact effect of short-range force due to Coulomb exchange between two system electrons. Both these interactions dominate at colder energies. The system is treated as a four-centre problem in the centre-of-mass frame. The present ab-initio model is useful to study the two-atomic collisions at low energies, as well as cold energies. The new code is applied to study the scattering of positronium (Ps) by hydrogen (H), both in their ground states.

    In previous work we showed that bright atomic solitons can arise in spinor Bose-Einstein condensates in the form of gap solitons even for repulsive many-body interactions. Here we further explore the properties of atomic gap solitons and show that their internal structure can be used to both excite them and control their center-of-mass motion using applied laser and magnetic fields. As an illustration we demonstrate a nonlinear atom-optical Mach-Zehnder interferometer based on gap solitons.

  16. Adiabatic control of atomic dressed states for transport and sensing

    Cooper, N. R.; Rey, A. M.

    2015-08-01

    We describe forms of adiabatic transport that arise for dressed-state atoms in optical lattices. Focusing on the limit of weak tunnel-coupling between nearest-neighbor lattice sites, we explain how adiabatic variation of optical dressing allows control of atomic motion between lattice sites: allowing adiabatic particle transport in a direction that depends on the internal state, and force measurements via spectroscopic preparation and readout. For uniformly filled bands these systems display topologically quantized particle transport. An implementation of the dressing scheme using optical transitions in alkaline-earth atoms is discussed as well as its favorable features for precise force sensing.

  18. Challenges of atomic energy regulation in Indian context

    International Nuclear Information System (INIS)

    Over the years, India has mastered all the stages of the nuclear fuel cycle, which include mining, processing and fabrication of nuclear fuel; design, construction, and operation of nuclear power reactors and research reactors; reprocessing of spent fuel and management of radioactive wastes. Ionising radiation is also used widely in medical, industrial and research areas. Since its inception, Department of Atomic Energy (DAE) was enforcing radiological safety in the country through in-house or ad-hoc committees, till a dedicated regulatory body (AERB) was set up 25 years ago. Today India is operating 19 nuclear power plants with different vintages (2 BWRs and 17 PHWRs) and another 8 (1 PFBR, 5 PHWRs and 2 PWRs) are in various stages of construction. Recently there are new evolutionary reactors (AHWRs) for which design has been completed and are on the threshold for consideration for construction. To match the rapid growth in the need for power India is also about to take up construction of large evolutionary PWRs of foreign design. This variety in the Indian nuclear power programme has come up due to a systematic evaluation and optimisation of the resources and technology available within the country. Added to this is the growing use of radiation in non-power applications. As the safety supervision of this huge programme is the responsibility of AERB, it faces various challenges, like, - Strategies for regulating wide variety of nuclear and radiation facilities with wide dispersal; - Meeting present day expectations with regard to nuclear and radiation safety and nuclear security; - The safety and security of large number of radioactive sources spread over such a vast country and of the associated import/export guidance; - Ensuring safety of old plants by periodic reviews and by prescribing adequate safety upgradation and ageing management programme; -Adaptation of the regulatory system and of regulations to new and foreign design nuclear technologies and

  20. Controlling interaction of ultracold atoms in an optical superlattice

    Duan, Luming

    2008-05-01

    First, I will briefly review the methods to control spin- exchange interaction for ultracold atoms in an optical lattice [1], and the recent experimental techniques to demonstrate the second-order tunneling responsible for the spin exchange interaction with a superlattice [2]. Then, I will discuss the interaction for strongly interacting atoms in a lattice near a wide Feshbach resonance. The strong interaction brings in a number of new features such as multi-band populations and direct neighboring interaction. Under certain circumstances, this complicated system can be described by an effective single- band model (the general Hubbard model) which has particle assisted tunneling for the atoms [3]. The particle assisted tunneling means that the effective atomic tunneling rate from the site i to j depends on whether there is another atom on these two sites. The particle assisted tunneling brings in new feature for quantum many-body physics. I will describe an experimental scheme to test the prediction of the particle assisted tunneling for strongly interacting atoms based on the use of the optical superlattice technique [4]. [1] L.-M.

  1. Seeking to Improve Low Energy Neutral Atom Detection in Space

    The detection of energetic neutral atoms allows for the remote examination of the interactions between plasmas and neutral populations in space. Before these neutral atoms can be measured, they must first be converted to ions. For the low energy end of this spectrum, interaction with a conversion surface is often the most efficient method to convert neutrals into ions. It is generally thought that the most efficient surfaces are low work functions materials. However, by their very nature, these surfaces are highly reactive and unstable, and therefore are not suitable for space missions where conditions cannot be controlled as they are in a laboratory. We therefore are looking to optimize a stable surface for conversion efficiency. Conversion efficiency can be increased either by changing the incident angle of the neutral particles to be grazing incidence and using stable surfaces with high conversion efficiencies. We have examined how to increase the angle of incidence from -80 degrees to -89 degrees, while maintaining or improving the total active conversion surface area without increasing the overall volume of the instrument. We are developing a method to micro-machine silicon, which will reduce the volume to surface area ratio by a factor of 60. We have also examined the material properties that affect the conversion efficiency of the surface for stable surfaces. Some of the parameters we have examined are work function, smoothness, and bond structure. We find that for stable surfaces, the most important property is the smoothness of the surface.

  2. Chameleon dark energy and atom interferometry

    2016-08-01

    Atom interferometry experiments are searching for evidence of chameleon scalar fields with ever-increasing precision. As experiments become more precise, so too must theoretical predictions. Previous work has made numerous approximations to simplify the calculation, which in general requires solving a three-dimensional nonlinear partial differential equation. This paper calculates the chameleonic force using a numerical relaxation scheme on a uniform grid. This technique is more general than previous work, which assumed spherical symmetry to reduce the partial differential equation to a one-dimensional ordinary differential equation. We examine the effects of approximations made in previous efforts on this subject and calculate the chameleonic force in a setup that closely mimics the recent experiment of Hamilton et al. Specifically, we simulate the vacuum chamber as a cylinder with dimensions matching those of the experiment, taking into account the backreaction of the source mass, its offset from the center, and the effects of the chamber walls. Remarkably, the acceleration on a test atomic particle is found to differ by only 20% from the approximate analytical treatment. These results allow us to place rigorous constraints on the parameter space of chameleon field theories, although ultimately the constraint we find is the same as the one we reported in Hamilton et al. because we had slightly underestimated the size of the vacuum chamber. This computational technique will continue to be useful as experiments become even more precise and will also be a valuable tool in optimizing future searches for chameleon fields and related theories.

    2016-07-01

    We theoretically investigate trapped ions interacting with atoms that are coupled to Rydberg states. The strong polarizabilities of the Rydberg levels increase the interaction strength between atoms and ions by many orders of magnitude, as compared to the case of ground-state atoms, and may be mediated over micrometers. We calculate that such interactions can be used to generate entanglement between an atom and the motion or internal state of an ion. Furthermore, the ion could be used as a bus for mediating spin-spin interactions between atomic spins in analogy to much employed techniques in ion-trap quantum simulation. The proposed scheme comes with attractive features as it maps the benefits of the trapped-ion quantum system onto the atomic one without obviously impeding its intrinsic scalability. No ground-state cooling of the ion or atom is required and the setup allows for full dynamical control. Moreover, the scheme is to a large extent immune to the micromotion of the ion. Our findings are of interest for developing hybrid quantum information platforms and for implementing quantum simulations of solid-state physics.

    We theoretically investigate trapped ions interacting with atoms that are coupled to Rydberg states. The strong polarizabilities of the Rydberg levels increases the interaction strength between atoms and ions by many orders of magnitude, as compared to the case of ground state atoms, and may be mediated over micrometers. We calculate that such interactions can be used to generate entanglement between an atom and the motion or internal state of an ion. Furthermore, the ion could be used as a bus for mediating spin-spin interactions between atomic spins in analogy to much employed techniques in ion trap quantum simulation. The proposed scheme comes with attractive features as it maps the benefits of the trapped ion quantum system onto the atomic one without obviously impeding its intrinsic scalability. No ground state cooling of the ion or atom is required and the setup allows for full dynamical control. Moreover, the scheme is to a large extent immune to the micromotion of the ion.

    Wondrak, Michael F.; Nicolini, Piero; Bleicher, Marcus

    2016-08-01

    In the present work we study the effect of unparticle modified static potentials on the energy levels of the hydrogen atom. By using Rayleigh-Schrödinger perturbation theory, we obtain the energy shift of the ground state and compare it with experimental data. Bounds on the unparticle energy scale ΛU as a function of the scaling dimension dU and the coupling constant λ are derived. We show that there exists a parameter region where bounds on ΛU are stringent, signaling that unparticles could be tested in atomic physics experiments.

    2006-01-01

    The energy and decay width of the pi-K atom are evaluated in the framework of the quasipotential-constraint theory approach. The main electromagnetic and isospin symmetry breaking corrections to the lowest-order formulas for the energy shift from the Coulomb binding energy and for the decay width are calculated. They are estimated to be of the order of a few per cent. We display formulas to extract the strong interaction S-wave pi-K scattering lengths from future experimental data concerning the pi-K atom.

  8. Development of small reactor safety criteria in Canada

    International Nuclear Information System (INIS)

    A number of new small reactor designs have been proposed in Canada over the last several years and some have reached the stage where licensing discussions have been initiated with the Atomic Energy Control Board (AECB). An inter-organizational Small Reactor Criteria (SRC) working group was formed in 1988 to propose safety and licensing criteria for these small reactors. Two levels of criteria are proposed. The first level forms a safety philosophy and the second is a set of criteria for specific reactor applications. The safety philosophy consists of three basic safety objectives together with evaluation criteria, and fourteen fundamental principles measured by specific criteria, which must be implemented to meet the safety objectives. Two of the fourteen principles are prime: defence in depth, and safety culture; the other twelve principles can be seen as deriving from them. A benefit of this approach is that the concepts of defence in depth and safety culture become well-defined. The objectives and principles are presented in the paper and their criteria are summarized. The second level of criteria, under development, will form a safety application set and will provide small reactor criteria in a number of general areas, such as regulatory process and safety assessment, as well as for specific reactor life-cycle activities, from siting through to decommissioning. The criteria are largely deterministic. However, the frequencies and consequences of postulated accidents are assessed against numerical criteria to assist in judging the acceptability of plant design, operation, and proposed siting. All criteria proposed are designed to be testable in some evidentiary fashion, readily enabling an assessment of compliance for a given proposal

  9. Particle beam technology for control of atomic-bonding state in materials

    1997-03-01

    The atomic-bonding state in materials can be controlled through `kinetic bonding` process by energetic particle beams which have a sufficient atomic kinetic energy. In order to clarify the `kinetic bonding` process the negative-ion beam deposition is considered as an ideal method because the negative ion has no additional active energies. Sputter type heavy negative-ion sources can be used for this purpose. Carbon films prepared by carbon negative-ion beam deposition have a strong dependency of the film properties on ion beam kinetic energy and have a quite high thermal conductivity which is comparable to that of the IIb diamond at a kinetic energy of 50-100 eV/atom. It suggests that new or metastable materials could be formed through the `kinetic bonding` process. Negative-ion beams can also be used for ion implantation, in which charging problems are perfectly reduced. (author)

  10. Basic plan of development and utilization of atomic energy, 1980

    International Nuclear Information System (INIS)

    The stable acquisition of energy is indispensable for the maintenance and improvement of national living standard and the development of social economy. The supply of oil tends to be tight in medium and long term perspective. Japan must acquire oil stably, save oil consumption as far as possible, and develop substitute energy. The development and utilization of atomic energy must be promoted as the most important subject in the energy policy because it is the most promising substitute energy. The nuclear power stations in operation in Japan are 21 plants with 15 million kW capacity, and it is equivalent to 12% of the total power generation. Adding the plants under construction and in preparation, the total becomes 35 plants and 28 million kW, but the construction is behind schedule due to the difficulty in the location of new power stations. As for the research and development on atomic energy, the establishment of nuclear fuel cycle such as the enrichment of uranium, the reprocessing of fuel and the treatment and disposal of radioactive wastes, the development of power reactors of new types, the research on nuclear fusion and so on have been endeavored. The maintenance of health of people and the preservation of environment are the prerequisities to the promotion of atomic energy. Japan contributes to form the new order on the basis of the results of INFCE. The development and utilization of atomic energy in 1980 are forwarded based on the basic policy described. (Kako, I.)

  12. An atomic clockwork using phase dependent energy shifts

    De Munshi, D; Mukherjee, M

    2011-01-01

    A frequency stabilized laser referenced to an unperturbed atomic two level system acts as the most accurate clock with femtosecond clock ticks. For any meaningful use, a Femtosecond Laser Frequency Comb (FLFC) is used to transfer the atomic clock accuracy to electronically countable nanosecond clock ticks. Here we propose an alternative clockwork based on the phenomenon that when an atomic system is slowly evolved in a cyclic path, the atomic energy levels gather some phase called the geometric phase. This geometric phase dependent energy shift has been used here to couple the two frequency regimes in a phase coherent manner. It has also been shown that such a technique can be implemented experimentally, bypassing the highly involved setup of a FLFC.

  13. Non—conservation of energy arising from atomic dipole interactions and its effects on light field and coupled atoms

    DongChuan-Hua

    2003-01-01

    The interactions between coulpled atoms and a single mode of a quantized electromagnetic field, which involve the terms originating from the dipole interactions, are discussed. In the usual Jaynes-Cummings model for coupled atoms, the terms of non-conservation of energy originating from dipole interactions are neglected, however, we take them into consideration in this paper. The effects of these terms on the evolutions of quantum statistic properties and squeezing of the field, the squeezing of atomic dipole moments and atomic population inversion are investigated. It has been shown that the coupling between atoms modulates these evolutions of fields and atoms. The terms of non-conservation of energy affect these evolutions of field and atoms slightly. They also have effects on the squeezing of the field, the squeezing of atomic dipole and atomic population inversions. The initial states of atoms also affect these properties.

  1. Chameleon Dark Energy and Atom Interferometry

    CERN Document Server

    Elder, Benjamin; Haslinger, Philipp; Jaffe, Matt; Müller, Holger; Hamilton, Paul

    2016-01-01

    Atom interferometry experiments are searching for evidence of chameleon scalar fields with ever-increasing precision. As experiments become more precise, so too must theoretical predictions. Previous work has made numerous approximations to simplify the calculation, which in general requires solving a 3-dimensional nonlinear partial differential equation (PDE). In this paper, we introduce a new technique for calculating the chameleonic force, using a numerical relaxation scheme on a uniform grid. This technique is more general than previous work, which assumed spherical symmetry to reduce the PDE to a 1-dimensional ordinary differential equation (ODE). We examine the effects of approximations made in previous efforts on this subject, and calculate the chameleonic force in a set-up that closely mimics the recent experiment of Hamilton et al. Specifically, we simulate the vacuum chamber as a cylinder with dimensions matching those of the experiment, taking into account the backreaction of the source mass, its o...

  2. Controlling the Multiport Nature of Bragg Diffraction in Atom Interferometry

    CERN Document Server

    Parker, Richard H; Estey, Brian; Zhong, Weicheng; Huang, Eric; Müller, Holger

    2016-01-01

    Bragg diffraction has been used in atom interferometers because it allows signal enhancement through multiphoton momentum transfer and suppression of systematics by not changing the internal state of atoms. Its multi-port nature, however, can lead to parasitic interferometers, allows for intensity-dependent phase shifts in the primary interferometers, and distorts the ellipses used for phase extraction. We study and suppress these unwanted effects. Specifically, phase extraction by ellipse fitting and the resulting systematic phase shifts are calculated by Monte Carlo simulations. Phase shifts arising from the thermal motion of the atoms are controlled by spatial selection of atoms and an appropriate choice of Bragg intensity. In these simulations, we found that Gaussian Bragg pulse shapes yield the smallest systematic shifts. Parasitic interferometers are suppressed by a "magic" Bragg pulse duration. The sensitivity of the apparatus was improved by the addition of AC Stark shift compensation, which permits d...

  6. Control of decisions in proceedings at administrative courts relating to the Federal Act for Protection Against Nuisances and to the Atomic Energy Law

    International Nuclear Information System (INIS)

    The author examines especially those lawsuits where the judicial decision depends - among other things - on the prior settling of most difficult technological questions. The decision on Kalkar given by the Federal Court of Justice is so important because it confirms that largely unclear legal terms are unobjectionable from the point of view of constitutional law. Using other findings, the author discusses the extension of legal protection as to include earlier stages of licensing procedures, foreclosure, the tightness of controls in case of review and subsequent assessment of difficult scientific or technological issues, risk assessment and its evaluation by the executive and judiciary. Law leaves final decision and assessment up to the executive power, the review of the framework up to the court. The problems mentioned can be solved without having to set up a science court or to install a judge who is an expert in technologies. (HSCH)

    The procedures for nuclear material control are reviewed, based on the experiences at the Japan Atomic Energy Research Institute. Nuclear materials to be discussed here include: - Both natural and enriched uranium for research; - Imported enriched nuclear fuel elements for JRR-2 (10-MW CP-5), JRR-4 (1-MW swimming pool), JPDR (12.5-MW(e) BWR), and the critical assemblies for JMTR (50-MW light-water moderated) and for the propulsion reactor; - Domestically-fabricated natural uranium fuel elements for JRR-3 (10-MW heavy-water moderated); - Domestically-fabricated fuels for the critical assemblies manufactured from imported enriched uranium oxides; - Domestically-fabricated enriched fuel elements for JPDR and for the propulsion reactor manufactured from imported enriched uranium hexafluoride. Both thorium and plutonium are also under control, but excluded from the present paper. Entire administrative pattern for nuclear material control is first presented. The emphasis is placed on the domestic fabrication of enriched fuel elements from imported enriched uranium, and the details of the control procedures during and after the fabrication process are discussed. The control procedures include the chemical analysis for purity check, isotopic assay by mass spectrometry, physical and mechanical tests of fabricated products, and the careful prevention in the diversion of nuclear materials. Administrative problems being attributed to Japanese domestic situation are presented; for example, the segregation, collection and efficient recovery and practical uses of residual uranium from the fabrication process. Methods for keeping records on the storage and uses of nuclear materials are also discussed. More satisfactory control procedures for other nuclear materials such as thorium and heavy water are under progress. (author)

    This post-doctoral thesis of 1981 has been updated to include developments in this field up to the year 1983. The author discusses in detail all questions relating to the peaceful uses of nuclear energy in the Federal Republic of Germany, predominantly from the point of view of administrative law. He investigates nuclear energy and its contribution to electricity supplies with a view to other energy sources, renewable energy sources, alternative energy policies, nuclear fuel and the fuel cycle, development of the nuclear industry, nuclear power stations in operation, under construction, or in development. Following a survey of the nuclear controversy, both on the national and the international level, the author reviews the legal system and arising controversies in the Federal Republic of Germany, defining the purpose of this thesis to be the systematic analysis of the available legal instruments, in order to show structural deficiencies in the planning law relating to nuclear power stations, and thus reasons of ambiguities within the licensing procedure. The author studies the following terms and requirements: licensing requirements and licensability, the licensing method and scenario, the legal character of licences, their contents and effects within the stepwise procedure, and due publication.

  11. Controlling the dynamics of a single atom in lateral atom manipulation.

    Science.gov (United States)

    Stroscio, Joseph A; Celotta, Robert J

    2004-10-01

    We studied the dynamics of a single cobalt (Co) atom during lateral manipulation on a copper (111) surface in a low-temperature scanning tunneling microscope. The Co binding site locations were revealed in a detailed image that resulted from lateral Co atom motion within the trapping potential of the scanning tip. Random telegraph noise, corresponding to the Co atom switching between hexagonal close-packed (hcp) and face-centered cubic (fcc) sites, was seen when the tip was used to try to position the Co atom over the higher energy hcp site. Varying the probe tip height modified the normal copper (111) potential landscape and allowed the residence time of the Co atom in these sites to be varied. At low tunneling voltages (less than approximately 5 millielectron volts), the transfer rate between sites was independent of tunneling voltage, current, and temperature. At higher voltages, the transfer rate exhibited a strong dependence on tunneling voltage, indicative of vibrational heating by inelastic electron scattering.

  16. Bremsstrahlung spectra from atoms and ions at low relativistic energies

    International Nuclear Information System (INIS)

    Analytic expressions for bremsstrahlung spectra from neutral atoms and ions, including the polarizational bremsstrahlung contribution in a stripped atom approximation, are developed for electron scattering at energies of 10-2000 keV. A modified Elwert factor and a simple higher Born correction are used for the Coulomb spectrum, with ordinary bremsstrahlung screening effects in ions and atoms adequately characterized in the non-relativistic Born approximation. In parallel with the development of this analytic description, new numerical results are obtained for ordinary bremsstrahlung from ions and from bare nuclei, appreciably extending the available data set which can be used to study dependences on element, ionicity, energy and the fraction of incident energy radiated. The accuracy of predictions with the analytic expressions is then determined by comparison with the full numerical relativistic partial-wave results for ordinary bremsstrahlung and with non-relativistic numerical results in the Born approximation or in partial waves for the polarizational amplitude.

    1999-08-01

    The factors, by which the modern engineering ethics has been profoundly affected, were classified to three categories, namely mental blow, the destruction of human function and environment damage. The role of atomic energy engineering in the ethic field has been shown in the first place. It is pointed out that it has brought about the mental blow by the elucidation of universal truth and discipline and the functional disorder by the power supply. However, the direct effect of radiation to the human kinds is only a part of the stresses comparing to the accumulation of the social stress which should be taken into account of by the possibility of disaster and the suspicion of the atomic energy politics. An increase in the multiple stresses as well as the restriction of criticism will place obstacles on the promotion of atomic energy. (author)

    Two nonlinear control techniques are proposed for an atomic force microscope system.Initially,a learning-based control algorithm is developed for the microcantilever-sample system that achieves asymptotic cantilever tip tracking for periodic trajectories.Specifically,the control approach utilizes a learning-based feedforward term to compensate for periodic dynamics and high-gain terms to account for non-periodic dynamics.An adaptive control algorithm is then developed to achieve asymptotic cantilever tip tracking for bounded tip trajectories despite uncertainty throughout the system parameters.Simulation results are provided to illustrate the efficacy and performance of the control strategies.

  2. Distributed wind generation : another path for wind energy development in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Pynn, P. [Eon Windelectric, Upper Tantallon, NS (Canada)

    2008-07-01

    This presentation examined methods of promoting distributed wind energy (DWE) in Canada. Distributed wind generation is locally generated, under 10 MW, and typically connected at distribution voltages or lower. Distributed wind generation is often used by commercial enterprises to generate their own power, as well as by governments, institutions, and communities. DWE avoids the necessity for transmission and generation upgrades and provides reductions in peak demand. Although DWE can contribute to the economic development of rural areas, the capital costs are often high. Financial incentives needed to promote DWE in rural areas of Canada include request for proposals (RFPs); feed-in tariffs; renewable energy credits (RECs); net metering; and tax incentives. As a means of promoting DWE, Germany is now providing priority grid access for renewable energy. Germany is also providing guaranteed grid access and fixed price tariffs. DWE programs are seen as a popular method of addressing climatic change. Under the German system, developers are required to pay up to the point of interconnection, while the utility pays for grid upgrades. The federal bank provides lower interest loans for renewable energy. It was concluded that while smaller turbines are often used for DWE, the high costs and complex installation procedures remain a challenge to many communities. Case studies of DWE projects in Colorado, the Dominican Republic, and Nova Scotia were included. tabs., figs.

    Full Text Available Accurate and stable high frequency pulse power supply is studied to improve high-speed wedm machine tool's efficiency. Regarding to the shortcomings of traditional digital circuit high frequency oscillator board, we design a high frequency power oscillator board based on rotary encoder control, control accuracy and high-frequency waveform by programming, adjusting the frequency and display. It has six brakes of processing function, it also includes feedback function of emulsification oil. The high frequency will be shutdown and the emulsification oil will be changed if there is too much metal dust in emulsification. It has been proved by practice that high-frequency circuit board is simple and reliable and can greatly increase efficiency of wire cutting.

    If dark energy --- which drives the accelerated expansion of the universe --- consists of a light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. Chameleon fields and other theories with screening mechanisms, however, can evade these tests by suppressing the forces in regions of high density, such as the laboratory. Using a cesium matter-wave interferometer near a spherical mass in an ultra-high vacu...

    2011-01-01

    In response to the dominance of green capitalist discourses in Canada's environmental movement, in this paper, we argue that strategies to improve energy policy must also provide mechanisms to address social conflicts and social disparities. Environmental justice is proposed as an alternative to mainstream environmentalism, one that seeks to address systemic social and spatial exclusion encountered by many racialized immigrants in Toronto as a result of neo-liberal and green capitalist municipal policy and that seeks to position marginalized communities as valued contributors to energy solutions. We examine Toronto-based municipal state initiatives aimed at reducing energy use while concurrently stimulating growth (specifically, green economy/green jobs and 'smart growth'). By treating these as instruments of green capitalism, we illustrate the utility of environmental justice applied to energy-related problems and as a means to analyze stakeholders' positions in the context of neo-liberalism and green capitalism, and as opening possibilities for resistance.

  9. Fueling the dragon : China's quest for energy security and Canada's opportunities

    Energy Technology Data Exchange (ETDEWEB)

    2005-04-01

    Potential opportunities for Canada were discussed in relation to China's growing economy. China's current dependency on foreign oil is approximately 40 per cent, and is expected to be over 60 per cent in less than 2 decades. With less than 4 per cent of global Gross Domestic Product (GDP), China consumes 31 per cent of the world's coal, 30 per cent of its iron, 27 per cent of steel and 40 per cent of cement. China is also currently building one of the most extensive highway infrastructures on earth so it can replace its 1 billion bicycles with cars. As a developing country, China is not subject to the emission reduction standards of the Kyoto Protocol. China has signed billions of dollars in agreements to buy energy and build pipelines, as well as opened doors for multinational corporations to enter China's domestic energy market. Canada is now competing for the pending award of contracts to build 4 nuclear reactors in China. Chinese interest in Canada is largely due to its huge oil reserves, particularly now that Alberta's oil sands have been classified as economically recoverable. A background of Chinese and Canadian relations was presented. In 2003, The Common Paper of the Canada-China Strategic Working Group was developed, in which both countries agreed to strengthen their bilateral dialogue on energy, research and development and sustainable development. Official endorsements have been followed by real business movement, with Chinese interest in buying stakes in the oil sands industry. However, unlike other resource rich countries, Canada has yet to strike a major deal with China, and any major energy cooperation between China and Canada will be closely watched by the United States. Canada is the largest source of imported oil for the United States. It was concluded that the broader strategic implications of Canada's relationship with China must be carefully considered. 5 figs.

    2013-02-01

    Atomic Force Microscopes (AFM) are used for generating surface topography of samples at micro to atomic resolutions. Many commercial AFMs use piezoelectric tube nanopositioners for scanning. Scanning rates of these microscopes are hampered by the presence of low frequency resonant modes. When inadvertently excited, these modes lead to high amplitude mechanical vibrations causing the loss of accuracy, while scanning, and eventually to break down of the tube. Feedback control has been used to damp these resonant modes. Thereby, enabling higher scanning rates. Here, a multivariable controller is designed to damp the first resonant mode along both the x and y axis. Exploiting the inherent symmetry in the piezoelectric tube, the multivariable control design problem is recast as independent single-input single-output (SISO) designs. This in conjunction with integral resonant control is used for damping the first resonant mode. PMID:23464216

  12. Energy management systems on board of electric vehicles, based on power electronics

    Energy Technology Data Exchange (ETDEWEB)

    Guidi, Giuseppe

    2009-03-15

    The core of any electric vehicle (EV) is the electric drive train, intended as the energy conversion chain from the energy tank (typically some kind of rechargeable battery) to the electric motor that converts the electrical energy into the mechanical energy needed for the vehicle motion. The need for on-board electrical energy storage is the factor that has so far prevented pure electric vehicles from conquering significant market share. In fact electrochemical batteries, which are currently the most suitable device for electrical energy storage, have serious limitations in terms of energy and/or power density, cost and safety. All those characteristics reflect in pure electric vehicles being outperformed by standard internal combustion engine (ICE) based vehicles in terms of driving range, time needed to refuel and purchase cost. Electric vehicles do have their distinctive advantages, being intrinsically much more efficient, operating at zero emissions at the pipe, and offering a higher degree of controllability that can potentially enhance driving safety. No wonder then, that electric energy storage technology has attracted considerable R&D investments, resulting in new traction battery packs that are getting closer and closer to the industrial targets. In this scenario of EV technology gaining momentum, power electronics engineers have to come up with newer solutions allowing for more efficient and more reliable utilization of the precious on-board energy that comes in a form that cannot be directly utilized by the motor. At present, most of the research in the area of power electronics for automotive is focused in volume and cost reduction techniques. The increase in power density is pursued by developing components that can be operated at higher temperature, thus relieving the requirements on cooling. In this thesis, the focus is on the development of alternative topologies for the power electronics converters that make use of some peculiarities of the energy

  4. Advancing district energy development in Canada : a process for site selection, review and community participation

    International Nuclear Information System (INIS)

    Municipalities are giving greater consideration to the role of energy in the design, development, and operation of communities. Organizations and governments around the world are beginning to assess various energy risks beyond just the generation or delivery of energy. Municipalities planning for population growth no longer include only the potential increases in revenue from property taxes or the requirement to expand urban growth boundaries to accommodate new development. Energy planning requires an understanding of how communities can reduce greenhouse gas (GHG) emissions and local energy consumption. This report presented the development of a process in order to assist decision makers, business leaders and local citizens in reviewing the role of energy in urban regions and how district energy (DE) can be part of the solution. The report presented an overview of the approach developed to identify 10 communities across Canada for the application of DE to assist with urban revitalization, brownfield remediation, community economic development, and sustainable energy conservation. The report outlined the development of an energy selection framework and how the framework could be replicated in urban regions to identify the interest in a community for DE. It was concluded that development of a DE system is complex and requires consideration for the interaction of land use policies and energy supply goals, the support of senior decision makers at the public and private level, an open dialogue between planners, engineers, utility operators and developers, as well as an informed and involved citizens. 3 tabs., 1 fig., 8 appendices

    2008-05-01

    By loading spinor atoms in optical lattices it is now possible to experimentally implement quantum spin models in a controlled environment, and to investigate quantum magnetism in strongly correlated systems. In this talk we will describe a novel approach to prepare, detect and control super-exchange interactions in ultracold spinor atoms loaded in optical superlattices [1]. Recently this approach was used for the first experimental observation of super-exchange interactions in ultra-cold atoms [2]. The many-body dynamics arising from the coherent coupling between singlet-triplet pairs in adjacent double-wells will be also discussed, in particular how it can lead to the formation of spin states with a high degree of multi-particle entanglement. Finally, we will present an extension of this approach to prepare and detect in a controllable way d-wave superfluidity in an array of weakly coupled plaquettes loaded with fermionic atoms. [1] A. M.

  7. Correlated energy transfer between two ultracold atomic species

    Science.gov (United States)

    Krönke, Sven; Knörzer, Johannes; Schmelcher, Peter

    2015-05-01

    We study a single atom as an open quantum system, which is initially prepared in a coherent state of low energy and oscillates in a one-dimensional harmonic trap through an interacting ensemble of NA bosons, held in a displaced trap [arXiv:1410.8676]. The non-equilibrium quantum dynamics of the total system is simulated by means of an ab-initio method, giving us access to all properties of the open system and its finite environment. In this talk, we focus on unraveling the interplay of energy exchange and correlations between the subsystems, which are coupled in such a spatio-temporally localized manner. We show that an inter-species interaction-induced level splitting accelerates the energy transfer between the atomic species for larger NA, which becomes less complete at the same time. System-environment correlations prove to be significant except for times when the excess energy distribution among the subsystems is highly imbalanced. These correlations result in incoherent energy transfer processes, which accelerate the early energy donation of the single atom. By analyzing correlations between intra-subsystem excitations, certain energy transfer channels are shown to be (dis-)favored depending on the instantaneous direction of transfer.

    The atomic energy power generation is recognized to be important to solve the problems of the competitive relations among the Asian developing countries due to the increasing dependency on the crude oil produced in the Middle East and the insecurity of transport route of the oil. The reorganization and inauguration of JNC(former PNC) has been carried out for the development of liquid metal reactor and related fuel cycle technology as the national development project to prevent the global green house effect and to continue the economic development. The construction of light water reactor, the utilization of plutonium in light water reactor and the enrichment and reprocessing of spent fuel of light water reactor are classified as proven technologies which will be covered by the industry. The government will lead to the environment favorable for introduction of the atomic energy and will monitor the situation. The specifics of atomic energy development project and the development system for the 21th century will be contained in the long term atomic energy development plan which will be completed by 2000 and the reorganization operation has been initiated.

  19. International Atomic Energy Agency Annual Report 2014

    International Nuclear Information System (INIS)

    Along with an examination of the state of worldwide nuclear-related developments last year, the IAEA Annual Report 2014 provides a comprehensive look at the Agency’s activities over the course of the year. From coordinating 125 research projects to conducting 2114 nuclear verification inspections worldwide, the IAEA’s 2560 employees continued to work on a wide range of areas to meet the evolving needs of Member States. The Annual Report, published in August, will be discussed and endorsed at the IAEA’s General Conference in September. Serving 162 Member States, two more than the year before, the IAEA’s activities in 2014 focused on the following areas, in line with its mandate: • Nuclear Energy: The IAEA assisted Member States in the introduction of nuclear power programmes and in the efficient and safe use of nuclear energy, fostering innovation and building capability in energy planning, analysis, and nuclear information and knowledge management. • Nuclear Sciences and Applications: The IAEA continued to assist Member States in building, strengthening and maintaining capacities in the safe, peaceful and secure use of nuclear technology. • Nuclear Safety and Security: The IAEA and its Member States continued to strengthen nuclear safety worldwide, including through the implementation of the Action Plan on Nuclear Safety, which had been endorsed by the General Conference in 2011 after the accident at the Fukushima Daiichi nuclear power plant earlier that year. The IAEA also supported States, upon request, in their efforts to achieve effective security wherever nuclear and other radioactive materials are in use. • Nuclear Verification: The IAEA implemented safeguards in 180 States and as at the end of every year, it drew conclusions for each State for which safeguards were applied. • Technical Cooperation: The IAEA assisted Member States in their efforts to achieve the Millennium Development Goals and in preparation for the post-2015 Sustainable

  20. The World Power Conference and atomic energy

    International Nuclear Information System (INIS)

    The possibility that emerged after the last World War that useful power could be produced from nuclear fission led to optimistic estimates that nuclear power would prove to be the solution to the world's energy problems. The possible advantages of nuclear methods of power production compared with conventional means are discussed at the World Power Conference. The 1962 Conference with its theme 'The Changing Pattern of Power' will undoubtedly attract great interest in a world where the change-over from conventional to nuclear fuels for power production has started in some countries and is being actively examined in others. It is generally being realized that even though a country may possess indigenous supplies of uranium or thorium minerals, the building up of a nuclear industry i s a long and expensive process and the alternative of depending on countries more advanced in nuclear technology for the supply of materials, skill and know-how is costly in foreign exchange and international prestige. Many of the industrialized countries, still possessing supplies of conventional fuels, are preparing for the day when their reserves will become depleted and are embarking on training schemes to ensure a continuing supply of engineers and scientists skilled in nuclear arts

    Considering the nuclear motion, we present the nonrelativistic ground energy of a helium atom by using a simple effective variational wavefunction with a flexible parameter k. Based on the result, the relativistic and radiative corrections to the nonrelativistic Hamiltonian are discussed. The high precision value of the helium ground energy is evaluated to be -2.90338 a.u. With the relative error 0.00034%.

    1999-01-01

    The NASA Langley Research Center's Wind Tunnel Reinvestment project plans to shrink the existing data acquisition electronics to fit inside a wind tunnel model. Space limitations within a model necessitate a distributed system of Application Specific Integrated Circuits (ASICs) rather than a centralized system based on PC boards. This thesis will focus on the design of the prototype of the communication Controller board. A portion of the communication Controller board is to be used as the basis of an ASIC design. The communication Controller board will communicate between the internal model modules and the external data acquisition computer. This board is based around an Field Programmable Gate Array (FPGA), to allow for reconfigurability. In addition to the FPGA, this board contains buffer Random Access Memory (RAM), configuration memory (EEPROM), drivers for the communications ports, and passive components.

    This work is the result of a collaboration between INESC and LIP in the CMS experiment being conducted at CERN. The collaboration addresses the application of boundary scan test at system level namely the development of a VME boundary scan controller (BSC) board prototype and the corresponding software. This prototype uses the MTM bus existing in the VME64* backplane to apply the 1149.1 test vectors to a system composed of nineteen boards, called here units under test (UUTs). A top-down approach is used to describe our work. The paper begins with some insights about the experiment being conducted at CERN, proceed with system level considerations concerning our work and with some details about the BSC board. The results obtained so far and the proposed work is reviewed in the end of this contribution. (11 refs).

    1991-01-01

    Approximately 200 Canada geese (Branta canadensis) died at a playa lake in the Texas Panhandle shortly after a winter wheat field in the basin adjacent to the lake was treated with parathion to control newly invading Russian wheat aphids (Diuraphis noxia). No evidence of infectious disease was diagnosed during necropsies of geese. Brain ChE activities were depressed up to 77% below normal. Parathion residues in GI tract contents of geese ranged from 4 to 34 ppm. Based on this evidence, parathion was responsible for the goose mortalities. Parathion applications to winter wheat will undoubtedly increase if parathion is applied for control of both Russian wheat aphids and greenbugs (Schizaphis graminum). Geese may potentially be exposed to widespread applications of parathion from fall to spring, essentially their entire wintering period.

    1987-01-01

    The market for telecommunications services needs to be segmented into user classes having similar transmission requirements and hence similar network architectures. Use of the following transmission architecture was considered: satellite switched TDMA; TDMA up, TDM down; scanning (hopping) beam TDMA; FDMA up, TDM down; satellite switched MF/TDMA; and switching Hub earth stations with double hop transmission. A candidate network architecture will be selected that: comprises multiple access subnetworks optimized for each user; interconnects the subnetworks by means of a baseband processor; and optimizes the marriage of interconnection and access techniques. An overall network control architecture will be provided that will serve the needs of the baseband and satellite switched RF interconnected subnetworks. The results of the studies shall be used to identify elements of network architecture and control that require the greatest degree of technology development to realize an operational system. This will be specified in terms of: requirements of the enabling technology; difference from the current available technology; and estimate of the development requirements needed to achieve an operational system. The results obtained for each of these tasks are presented.

  9. Nuclear fuel cycles as reflected in the atomic energy laws

    International Nuclear Information System (INIS)

    The author measures the stations of the nuclear fuel cycles against the requirements laid down by the constitution and the Atomic Energy Act. All safety-relevant installations of the nuclear fuel cycles for LWR-type and FBR-type reactor stations are explained and defined in the first section of the book, stating facts and technical aspects including the capacity problems in connection with spent fuel management and the resulting need for interim storage facilities. The following sections on the legal aspects discuss the various installations in comparison to the legal requirements and definitions of the Atomic Energy Act. The author emphasizes the separation of competences for the determination of safety-relevant facts (natural sciences and engineering), and for weighting decisions on the required prevention of damage (state powers). The licensing requirements given in section 7, sub-sec. (2) Atomic Energy Act and their respective relationships are examined in detail. The lines of concretization emanating from section 7, sub-sec. (2), no. 3 Atomic Energy Act are followed up down to the lowest level of legislative powers, and essential deficits in the light of constitutional law are pointed out, together with suggestions for improvement. Within the frame of a constitutional interpretation of section 7, sub-sec. (2), no. 3 Atomic Energy Act, the author analyses the decisions of the Federal Constitutional Court concerning the protective obligations of the state and their validity with regard to future generations, showing that the Federal Constitutional Court applies higher safety standards than those currently used by the administrative bodies. On this basis, the author develops a national, arithmetical average of natural radiation burden to serve as a substantive criterion for determining the borderline between damage prevention and risk to be accepted.

    In this report we demonstrate a general method for affecting chemical reactions with a high degree of spatial control that has potentially wide applicability in science and technology. Our technique is based on complexing the delivery of liquid or gaseous materials through a cantilevered micropipette with an atomic force microscope that is totally integrated into a conventional optical microscope. Controlled etching of chrome is demonstrated without detectable effects on the underlying glass substrate. This simple combination allows for the nanometric spatial control of the whole world of chemical reactions in defined regions of surfaces. Applications of the technique in critical areas such as mask repair are likely.

    While prohibition has been the dominant regime of cannabis control in most countries for decades, an increasing number of countries have been implementing cannabis control reforms recently, including decriminalization or even legalization frameworks. Canada has held out from this trend, although it has among the highest cannabis use rates in the world. Cannabis use is universally criminalized, and the current (conservative) federal government has vowed not to implement any softening reforms to cannabis control. As a result of several higher court decisions, the then federal government was forced to implement a 'medical marijuana access regulations' program in 2001 to allow severely ill patients therapeutic use and access to therapeutic cannabis while shielding them from prosecution. The program's regulations and approval processes were complex and subject to extensive criticism; initial uptake was low and most medical marijuana users continued their use and supply outside the program's auspices. This year, the government introduced new 'marijuana for medical purposes regulations', which allow physicians to 'authorize' medical marijuana use for virtually any health condition for which this is considered beneficial; supply is facilitated by licensed commercial producers. It is expected that some 500,000 users, and dozens of commercial producers will soon be approved under the program, arguably constituting - as with medical marijuana schemes elsewhere, e.g. in California--de facto 'legalization'. We discuss the question whether the evolving scope and realities of 'medical cannabis' provisions in Canada offer a 'sneaky side door' or a 'better third way' to cannabis control reform, and what the potential wider implications are of these developments.

    MicroChannel plates (MCP) detectors are frequently used in space instrumentation for detecting a wide range of radiation and particles. In particular, the capability to detect non-thermal low energy neutral species is crucial for the sensor ELENA (Emitted Low-Energy Neutral Atoms), part of the package SERENA (Search for Exospheric Refilling and Emitted Natural Abundances) on board the BepiColombo mission to Mercury to be launched in 2014. ELENA is a TOF sensor, based on a novel concept ultra-sonic oscillating shutter (Start section)which is operated at frequencies up to 50 kHz; a MCP detector is used as a Stop section. It is aimed to detect neutral atoms in the range 10 eV - 5 keV, within 70° FOV, perpendicular to the S/C orbital plane. ELENA will monitor the emission of neutral atoms from the whole surface of Mercury thanks to the spacecraft motion. The major scientific objectives are the interaction between the environment and the planet, the global particle loss-rate and the remote sensing of the surface properties. In particular, surface release processes are investigated by identifying particles release from the surface, via solar wind-induced ion sputtering (100 eV) as well as Hydrogen back-scattered at hundreds eV. MCP absolute detection efficiency for very low energy neutral atoms (EMEFISTO facility of the Physical Institute of University of Bern (CH), measurements on three different type of MCPs coating have been performed providing the behaviors of MCP detection efficiency in the range 10eV-1keV. Outcomes from such measurements are here discussed.

  16. Arbitrary excitation of atomic hydrogen at high energies

    International Nuclear Information System (INIS)

    Because of the growing need of excitation cross-section data of atomic hydrogen by fully stripped heavy ions for the preparation of an atomic database for neutral-beam penetration in large tokamaks, we have calculated these data in the framework of the first-order Born approximation for n≤20 in the energy range of 0.1 to 1.5 MeV/amu. The present computed results are found to be in agreement with the existing observed results. From the present calculation it also appears that the contribution from subshells characterized by l>3 is always less than 2%

    The fabrication of porous nanocomposites is key to the advancement of energy conversion and storage devices that interface with electrolytes. Bismuth vanadate, BiVO4 , is a promising oxide for solar water splitting where the controlled fabrication of BiVO4 layers within porous, conducting scaffolds has remained a challenge. Here, the atomic layer deposition of bismuth vanadates is reported from BiPh3 , vanadium(V) oxytriisopropoxide, and water. The resulting films have tunable stoichiometry and may be crystallized to form the photoactive scheelite structure of BiVO4 . A selective etching process was used with vanadium-rich depositions to enable the synthesis of phase-pure BiVO4 after spinodal decomposition. BiVO4 thin films were measured for photoelectrochemical performance under AM 1.5 illumination. The average photocurrents were 1.17 mA cm(-2) at 1.23 V versus the reversible hydrogen electrode using a hole-scavenging sulfite electrolyte. The capability to deposit conformal bismuth vanadates will enable a new generation of nanocomposite architectures for solar water splitting. PMID:27246652

    1987-01-01

    For satellites to remain a vital part of future national and international communications, system concepts that use their inherent advantages to the fullest must be created. Network architectures that take maximum advantage of satellites equipped with onboard processing are explored. Satellite generations must accommodate various services for which satellites constitute the preferred vehicle of delivery. Such services tend to be those that are widely dispersed and present thin to medium loads to the system. Typical systems considered are thin and medium route telephony, maritime, land and aeronautical radio, VSAT data, low bit rate video teleconferencing, and high bit rate broadcast of high definition video. Delivery of services by TDMA and FDMA multiplexing techniques and combinations of the two for individual and mixed service types are studied. The possibilities offered by onboard circuit switched and packet switched architectures are examined and the results strongly support a preference for the latter. A detailed design architecture encompassing the onboard packet switch and its control, the related demand assigned TDMA burst structures, and destination packet protocols for routing traffic are presented. Fundamental onboard hardware requirements comprising speed, memory size, chip count, and power are estimated. The study concludes with identification of key enabling technologies and identifies a plan to develop a POC model.

    Mixing of discretized states in quantum magnets has a radical impact on their properties. Managing this effect is key for spintronics in the quantum limit. Magnetic fields can modify state mixing and, for example, mitigate destabilizing effects in single-molecule magnets. The exchange bias field has been proposed as a mechanism for localized control of individual nanomagnets. Here, we demonstrate that exchange coupling with the magnetic tip of a scanning tunnelling microscope provides continuous tuning of spin state mixing in an individual nanomagnet. By directly measuring spin relaxation time with electronic pump-probe spectroscopy, we find that the exchange interaction acts analogously to a local magnetic field that can be applied to a specific atom. It can be tuned in strength by up to several tesla and cancel external magnetic fields, thereby demonstrating the feasibility of complete control over individual quantum magnets with atomically localized exchange coupling.

    Atomic-vapor density change due to light induced atomic desorption (LIAD) is studied in paraffin-coated rubidium, cesium, sodium and potassium cells. In the present experiment, low-intensity probe light is used to obtain an absorption spectrum and measure the vapor density, while light from an argon-ion laser or discharge lamp is used for desorption. Potassium is found to exhibit significantly weaker LIAD from paraffin compared to Rb and Cs, and we were unable to observe LIAD with sodium. A simple LIAD model is applied to describe the observed vapor-density dynamics, and the role of the cell's stem is explored through the use of cells with lockable stems. The results of this work could be used to assess the use of LIAD for vapor-density control in magnetometers, clocks, and gyroscopes utilizing coated cells.

    2008-01-01

    An assumptive theoretical relationship is suggested to describe the property of molecular atomization energy and energy transfer rate in the initiation of explosions. To investigate the relationship between atomization energy and energy transfer rate, the number of doorway modes of explosives is estimated by the theory of Dlott and Fayer in which the rate is proportional to the number of normal mode vibrations. It was evaluated frequencies of normal mode vibrations of eight molecules by means of density functional theory (DFT) at the b3p86/6-31G(d,p) level. It is found that the number of doorway modes shows a linear correlation to the atomization energies of the molecules, which were also calculated by means of the same method. A mechanism of this correlation is discussed. It is also noted that in those explosives with similar molecular structure and molecular weight, the correlation between the atomization energy and the number of doorway modes is higher.

    The energy and decay width of the pi-K atom are evaluated in the framework of the quasipotential-constraint theory approach. The main electromagnetic and isospin symmetry breaking corrections to the lowest-order formulas for the energy shift from the Coulomb binding energy and for the decay width are calculated. They are estimated to be of the order of a few per cent. We display formulas to extract the strong interaction S-wave pi-K scattering lengths from future experimental data concerning ...

    When there is high information asymmetry between directors and managers,independent directors do not have enough information to perform their functions. Only when faced with a good internal information environment can such directors acquire enough information to provide advice and monitor managers,and only under these conditions can increasing their proportion on the board effectively reduce agency problems, such as driving managers to disclose information to investors. Using a sample of Chinese listed firms that voluntarily disclose their auditors’ reports on internal controls from 2007 to 2009, this study explores how the information acquisition costs of independent directors affect their monitoring effectiveness by investigating the disclosure decisions of their internal control audits. We find that when the information asymmetry between insiders and outside directors is low and the proportion of independent directors on a board is high, a firm is more likely to voluntarily disclose its internal control audit report.

    Tobacco use remains the leading cause of death and disability in Canada. Insufficient research capacity can inhibit evidence-informed decision making for tobacco control. This paper outlines a Canadian project to build research capacity, defined as a community's ability to produce research that adequately informs practice, policy, and future research in a timely, practical manner. A key component is that individuals and teams within the community must mutually engage around common, collectively negotiated goals to address specific practices, policies or programs of research. An organizing framework, a set of activities to build strategic recruitment, productivity tools, and procedures for enhancing social capital are described. Actions are intended to facilitate better alignment between research and the priorities of policy developers and service providers, enhance the external validity of the work performed, and reduce the time required to inform policy and practice.

The manufacturing process, similar to Scanning Tunneling Microscopy, takes place within an Ultra High Vacuum (UHV) chamber at a pressure of 10-10 torr. In order to create vibration isolation, and to keep internal noise to a minimum, a wireless link inside the UHV chamber becomes essential. We present a MATLAB simulation of the problem, and then demonstrate a hardware scheme between a Gumstix computer and a Linux based laptop for controlling nano-manipulators with three degrees of freedom. © 2011 IEEE.

    International Nuclear Information System (INIS)

    The annual report of the Department of Atomic Energy (DAE) of the Government of India for the period of the fiscal year 1980-81 surveys the work of DAE, its various constituent units and aided institutions. The main thrust of the DAE's programme in the country is directed towards peaceful uses of atomic energy - primarily for generation of electric power and also for application of radioisotopes and radiation in medicine, agriculture, and industry. The research and development (R and D) activities of the Bhabha Atomic Research Centre (BARC) at Bombay, the major R and D establishment of DAE, in the fields of nuclear physics, solid state physics, chemistry and materials science, isotope and radiation applications, reactor technology and radioactive waste management are described in detail. The R and D activities of the Reactor Research Centre at Kalpakkam and the aided institutions such as the Tata Institute of Fundamental Research and the Tata Memorial Centre, both at Bombay, and the Saha Institute of Nuclear Physics at Calcutta are reviewed in brief. Progress of the MHD project, the heavy water plant projects, the thermal research reactor R-5 project at BARC and nuclear power plant projects at Narora and Kalpakkam is surveyed. Performance of industrial production units such as nuclear power stations at Tarapur and Kota, the Nuclear Fuel Complex at Hyderabad, Atomic Minerals Division, ISOMED - the radiation sterilisation plant for medical products, the Indian Rare Earths Ltd., the Electronics Corporation of India Ltd., and the Uranium Corporation of India Ltd., is reported.

  9. Uranium tailings research at the Canada Centre for Mineral and Energy Technology (CANMET)

    International Nuclear Information System (INIS)

    There are over 100 million metric tons of uranium tailings on the surface of Canada, an amount that is expected to increase threefold by the end of the century. Because of their potential hazard to the environment and man, the Canada Centre for Mineral and Energy Technology (CANMET) began a major program ten years ago to examine the problem of uranium tailings management. Vegetation of uranium tailings has been successful using seed mixtures planted on the tailings surface pretreated by lime and fertilizer. Lysimeter tests on uranium tailings have demonstrated that surface treatment and the presence or absence of bacteria have a marked effect on the flow and chemistry of seepage water. Hydrogeochemical studies of the tailings have shown that acid conditions prevail in the upper zone of the tailings (i.e., above the water table) and that both radioactive and other toxic chemicals are concentrated near the bottom of the tailings. Work has been done in cooperation with others on the precipitation and removal of 226Ra from tailings water effluent by BaCl2. Investigation into pre-concentrating the ore prior to acid leaching has demonstrated that virtually all the radionuclides and sulphides can be concentrated into a fraction amounting to from 30 to 40 percent of the original feed, leaving a relatively clean tailing. We are still far from our objective of demonstrating, with reasonable assurance, effective methods for the long-term management of uranium tailings. An accelerated program is outlined

    Decamp (Dark Energy Survey Camera) is a new instrument designed to explore the universe aiming to reveal the nature of Dark Energy. The camera consists of 72 CCDs and 520 Mpixels. The readout electronics of DECam is based on the Monsoon system. Monsoon is a new image acquisition system developed by the NOAO (National Optical Astronomical Observatory) for the new generation of astronomical cameras. The Monsoon system uses three types of boards inserted in a Eurocard format based crate: master control board, acquisition board and clock board. The direct use of the Monsoon system for DECam readout electronics requires nine crates mainly due to the high number of clock boards needed. Unfortunately, the available space for DECam electronics is constrained to four crates at maximum. The major drawback to achieve such desired compaction degree resides in the clock board signal density. This document describes the changes performed at CIEMAT on the programmable logic of the Monsoon clock board aiming to meet such restricted space constraints. (Author) 5 refs.

  14. Controlled Reactions between Ultracold Alkali and Metastable Helium Atoms

    Flores, Adonis Silva; Knoop, Steven

    2016-01-01

    In an ultracold, optically trapped mixture of $^{87}$Rb and metastable triplet $^4$He atoms we have studied trap loss for different spin-state combinations, for which interspecies Penning ionization is the main two-body loss process. We observe long trapping lifetimes for the purely quartet spin-state combination, indicating strong suppression of Penning ionization loss by at least two orders of magnitude. For the other spin-mixtures we observe short lifetimes that depend linearly on the doublet character of the entrance channel. We compare the extracted loss rate coefficient with recent predictions of multichannel quantum-defect theory for reactive collisions involving a strong exothermic loss channel and find near-universal loss for doublet scattering. Our work demonstrates control of reactive collisions by internal atomic state preparation, which also implies magnetic field tunability.

  15. Coherently controlling Raman-induced grating in atomic media

    CERN Document Server

    Arkhipkin, V G; Timofeev, I V

    2015-01-01

    We consider dynamically controllable periodic structures, called Raman induced gratings, in three- and four-level atomic media, resulting from Raman interaction in a standing-wave pump. These gratings are due to periodic spatial modulation of the Raman nonlinearity and fundamentally differ from the ones based on electromagnetically induced transparency. The transmission and reflection spectra of such gratings can be simultaneously amplified and controlled by varying the pump field intensity. It is shown that a transparent medium with periodic spatial modulation of the Raman gain can be opaque near the Raman resonance and yet at the same time it can be a non-linear amplifying mirror. We also show that spectral properties of the Raman induced grating can be controlled with the help of an additional weak control field.

    Electromagnetic isotope separation at the China Institute of Atomic Energy (CIAE) is described. Calutron, Nier-Bernas and Freeman ion sources were constructed for ion implantation systems. It was found that some enriched isotope samples were contaminated more by lighter than by heavier neighbors. This phenomenon may be explained if the sputtered particles consist of a considerable percentage of ions. A computer inspection system for recording and processing operation data has been designed.

    1998-01-01

    We present a study of parity (P) violating contributions to the eigenenergies of stationary systems containing atoms in spatially inhomogeneous external electric fields. In this context the subtle interplay of P-violation and time reversal (T) invariance plays an important role. If the entire field configuration is chosen to exhibit chirality the energies are in general shifted by pseudoscalar contributions which change sign under a planar reflection of the field. To calculate the effects we ...

    1993-02-01

    Algorithms for on-board attitude determination and control of the Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX) have been expanded to include a constant gain Kalman filter for the spacecraft angular momentum, pulse width modulation for the reaction wheel command, an algorithm to avoid pointing the Heavy Ion Large Telescope (HILT) instrument boresight along the spacecraft velocity vector, and the addition of digital sun sensor (DSS) failure detection logic. These improved algorithms were tested in a closed-loop environment for three orbit geometries, one with the sun perpendicular to the orbit plane, and two with the sun near the orbit plane - at Autumnal Equinox and at Winter Solstice. The closed-loop simulator was enhanced and used as a truth model for the control systems' performance evaluation and sensor/actuator contingency analysis. The simulations were performed on a VAX 8830 using a prototype version of the on-board software.

  8. World situation of atomic energy and nuclear fuel cycle

    International Nuclear Information System (INIS)

    At the International Conference organized by the IAEA in May 1976, several sections dealt with problems of the production of atomic energy and of the nuclear fuel cycle. However, the whole spectrum of these problems was discussed including problems of economic policy, politics and ethical problems, too. Reports were presented on trends of the development of atomic energy in developed and developing countries. Besides the systems of nuclear power plants and the trends of their development, the Conference attached prominent importance to the supply of nuclear fuels and to the fuel cycle, respectively. Owing to important factors, the reprocessing of the spent nuclear fuel was emphasized. The problem area of the treatment of radioactive wastes, the protection of workers in immediate contact and of environment against radiations, the possibilities of ensuring nuclear safety, the degrees of hazards and the methods of protection of fast breeder reactors and up-to-date equipments were discussed. In contrast to earlier conferences the complex problem of the correlation of atomic energy to public opinion played an important role, too. (P.J.)

    The atomic energy power generation is recognized to be important to solve the problems of the competitive relations among the Asian developing countries due to the increasing dependency on the crude oil produced in the Middle East and the insecurity of transport route of the oil. The reorganization and inauguration of JNC(former PNC) has been carried out for the development of liquid metal reactor and related fuel cycle technology as the national development project to prevent the global green house effect and to continue the economic development. The construction of light water reactor, the utilization of plutonium in light water reactor and the enrichment and reprocessing of spent fuel of light water reactor are classified as proven technologies which will be covered by the industry. The government will lead to the environment favorable for introduction of the atomicenergy and will monitor the situation. The specifics of atomic energy development project and the development system for the 21th century will be contained in the long term atomic energy development plan which will be completed by 2000 and the reorganization operation has been initiated.

  10. Instrumentation and control aging management: A focus on electronic parts and boards

    International Nuclear Information System (INIS)

    Full text: The nuclear power industry is currently facing increasing aging and obsolescence issues with original equipment installed for instrumentation, control, and safety system applications. One area that needs attention is the aging of electronic boards and components used in instrumentation and control (I and C) systems in nuclear power plants (NPPs). In this context, EPRI has launched a project dedicated to NPP electronic component and board aging management. The goals of this project are: 1) to better understand the degradation mechanisms of I and C electronic systems; 2) to develop new methods to monitor prevalent mechanisms and forecast generic aging cases; and 3) to give guidelines for the aging management of I and C electronic systems. The ultimate objectives are: 1) to reduce the likelihood of losing plant availability due to a board or component failure; and 2) to reduce the global cost of maintenance by optimizing preventive maintenance tasks and the schedule for refurbishment or renewal. Degradation mechanisms of electronic boards in NPP - Aging mechanisms of electronic parts depend on technologies, manufacturing quality, and conditions of environment and operation. Aging of electronic parts is well documented in harsh environments (e.g., aerospace, military, or automotive industries data). However, only a small amount of data on electronic part failures in NPPs is available because the conditions are benign and the failure rates are supposed to be low. It is thus difficult to identify what will predominantly cause the aging of electronic systems after 20 or 30 years of operation. Usual causes are temperature, corrosion, temperature cycles, or extrinsic aggressions (Electrical Over Stress (EOS), Electro Static Discharges (ESD)). From field data and bibliographic analyses, we found that electrolytic capacitors, relays, potentiometers, power devices (thyristors, power transistors, etc.), optocouplers, on-board connectors, printed boards, integrated

  11. Hope over fear. The establishment of the International Atomic Energy Agency

    International Nuclear Information System (INIS)

    President Eisenhower's ''Atoms for Peace'' speech in 1953 started a process that led to the establishment of the International Atomic Energy Agency (IAEA). This study analyses the negotiations of the Statute of the Agency. It focuses on how the Agency's scope of action regarding safeguards was negotiated. The Statute is seen as a reflection of the dual purpose of the new Agency to promote peaceful uses of nuclear energy, and to control that peaceful nuclear activities receiving IAEA assistance are not diverted to military purposes. On one hand, the countries receiving assistance from the Agency accepted a degree of international control that represented a breakthrough in international relations. On the other hand, many countries strongly resented controls. Consequently, compromises had to be made in the course of the negotiations in order to reach a consensus. Thus, although the IAEA was established as a competent and technical body, the underlying compromises meant that its scope of actions was restricted. 6 refs

    This paper overviews the design of three sustainable low or net-zero energy solar homes in Canada. The major features of the houses are: 1. direct gain passive solar design that emphasizes utilization of distributed thermal mass in the equatorial-facing part of the ground floor; 2. a building-integrated photovoltaic-thermal system (BIPV/T); 3. a two-stage ground-source heat pump used to heat/cool air in the house or an air source heat pump using BIPV/T air as the source to heat a storage tank; 4. a floor heating system integrated in the floor mass of the direct gain zone; 5. a multizone programmable thermostat.

  13. Scattering of low-energy neutrinos on atomic shells

    International Nuclear Information System (INIS)

    We present a derivation of the total cross section for inelastic scattering of low-energy solar neutrinos and reactor antineutrinos on bound electrons, resulting in a transition of the electron to an excited state. The atomic-shell structure of various chemical elements is treated in terms of a nonrelativistic approximation. We estimate the interaction rates for modern neutrino detectors, in particular the Borexino and GEMMA experiments. We establish that in these experiments the effect can be safely neglected, but it could be accessible to future large-volume neutrino detectors with low energy threshold

  14. Assessment of renewable energy technologies for charging electric vehicles in Canada

    International Nuclear Information System (INIS)

    Electric vehicle charging by renewable energy can help reduce greenhouse gas emissions. This paper presents a data-intensive techno-economic model to estimate the cost of charging an electric vehicle with a battery capacity of 16 kW h for an average travel distance of 65 km from small-scale renewable electricity in various jurisdictions in Canada. Six scenarios were developed that encompass scale of operation, charging time, and type of renewable energy system. The costs of charging an electric vehicle from an off-grid wind energy system at a charging time of 8 h is 56.8–58.5 cents/km in Montreal, Quebec, and 58.5–60.0 cents/km in Ottawa, Ontario. However, on integration with a small-scale hydro, the charging costs are 9.4–11.2 cents/km in Montreal, 9.5–11.1 cents/km in Ottawa and 10.2–12.2 cents/km in Vancouver, British Columbia. The results show that electric vehicle charging from small-scale hydro energy integration is cost competitive compared charging from conventional grid electricity in all the chosen jurisdictions. Furthermore, when the electric vehicle charging time decreases from 8 to 4 h, the cost of charging increases by 83% and 11% from wind and hydro energy systems, respectively. - Highlights: • Techno-economic analysis conducted for EV charging from wind and hydro. • EV charging from hydro energy is cost competitive than from wind energy. • GHG mitigation estimated from operation of EV charged from renewable energy. • Sensitivity of key parameters on cost of charging considered

    Microchannel Plates (MCP) detectors are frequently used in space instrumentation for detecting a wide range of radiation and particles. In particular, the capability to detect non-thermal low energy neutral species is crucial for the sensor ELENA (Emitted Low-Energy Neutral Atoms), part of the package SERENA (Search for Exospheric Refilling and Emitted Natural Abundances) on board the BepiColombo mission of ESA to Mercury to be launched in 2015. ELENA is a Time of Flight (TOF) sensor, based on a novel concept using an ultra-sonic oscillating shutter (Start section), which is operated at frequencies up to 50 kHz; a MCP detector is used as a Stop detector. The scientific objective of ELENA is to detect energetic neutral atoms in the range 10 eV - 5 keV, within 76° FOV, perpendicular to the S/C orbital plane. ELENA will monitor the emission of neutral atoms from the whole surface of Mercury thanks to the spacecraft motion. The major scientific objectives are the interaction between the plasma environment and the planet’s surface, the global particle loss-rate and the remote sensing of the surface properties. In particular, surface release processes are investigated by identifying particles released from the surface, via solar wind-induced ion sputtering (MEFISTO facility of the Physical Institute of the University of Bern (CH), measurements on three different types of MCP (with and without coating) have been performed providing the detection efficiencies in the energy range 10eV - 1keV. Outcomes from such measurements are discussed here.

    Considering that three two-level atoms are initially in the GHZ single state and two of the atoms are simultaneously put into a cavity initially in the coherent state, we investigate the dipole squeezing properties of the two atoms inside the cavity under the condition of resonant interaction. It is shown that dipole squeezing properties of the two atoms inside the cavity are strongly affected by rotation manipulating of the atom outside the cavity.

    The KEK positron generator is controlled by means of a distributed microprocessor network. The control system is composed of three kinds of equipment: device controllers for the linac equipment, operation management stations and a communication network. Individual linac equipment has its own microprocessor-based controller. A multiple single board computer (SBC) system is used for communication control and for equipment surveillance; it has a database containing communication and linac equipment status information. The linac operation management that should be the most soft part in the control system, is separated from the multiple SBC system and is carried out by work-stations. The principle that every processor executes only one task is maintained throughout the control system. This made the software architecture very simple.

  20. Regulating outdoor advertisement boards; employing spatial decision support system to control urban visual pollution

    Unmanaged placement, size, location, structure and contents of outdoor advertisement boards have resulted in severe urban visual pollution and deterioration of the socio-physical living environment in urban centres of Pakistan. As per the regulatory instruments, the approval decision for a new advertisement installation is supposed to be based on the locational density of existing boards and their proximity or remoteness to certain land- uses. In cities, where regulatory tools for the control of advertisement boards exist, responsible authorities are handicapped in effective implementation due to the absence of geospatial analysis capacity. This study presents the development of a spatial decision support system (SDSS) for regularization of advertisement boards in terms of their location and placement. The knowledge module of the proposed SDSS is based on provisions and restrictions prescribed in regulatory documents. While the user interface allows visualization and scenario evaluation to understand if the new board will affect existing linear density on a particular road and if it violates any buffer restrictions around a particular land use. Technically the structure of the proposed SDSS is a web-based solution which includes open geospatial tools such as OpenGeo Suite, GeoExt, PostgreSQL, and PHP. It uses three key data sets including road network, locations of existing billboards and building parcels with land use information to perform the analysis. Locational suitability has been calculated using pairwise comparison through analytical hierarchy process (AHP) and weighted linear combination (WLC). Our results indicate that open geospatial tools can be helpful in developing an SDSS which can assist solving space related iterative decision challenges on outdoor advertisements. Employing such a system will result in effective implementation of regulations resulting in visual harmony and aesthetic improvement in urban communities.
