  1. 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

  3. 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

  8. 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

    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.

  14. 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

  15. Epp names new interim execs to head Atomic Energy Canada

  19. 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

  20. 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.

  5. 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

    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

    TransCanada Pipelines Limited and its fully owned subsidiary TransCanada Keystone Pipeline GP Ltd. applied to the National Energy Board in June 2006 for leave to transfer certain pipeline facilities comprising part of TransCanada's mainline natural gas transmission system from TransCanada to Keystone for use in Keystone's proposed new oil pipeline. The transfer would involve the conversion of the facilities from gas service to oil service for use in the Keystone Project. The new oil pipeline would extend from Hardisty Alberta to Wood River and Patoka, Illinois. It would initially provide access for western Canada crude oil producers to the southern Petroleum Administration Defence District (PADD) 2 region of the United states. This is a major refining area which presently has minimal access for western Canada crude oil because of the limited pipeline capacity into the region. The Board held a hearing process to seek the views of interested parties regarding the list of issues that should be considered in dealing with the application. The list of issues included arguments of the Communications, Energy and Paperworkers Union of Canada (CEP) regarding the Board's jurisdiction; regulatory standards; energy supply markets and pipelines; potential impacts of the transfer such as potential costs to gas shippers and the impact of the transfer on mainline operations; and, the transfer at net book value (NBV). This document presented the Board's views on the transfer and the public interest. After considering all factors, the Board approved the sale and purchase of the Facilities from TransCanada to Keystone. The Board further ordered that TransCanada may reduce the mainline rate base by the NBV of the facilities upon their transfer to Keystone, and that Keystone may include the NBV in its pipeline oil plant upon the transfer of the facilities. 5 tabs., 14 figs., 6 appendices.

    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.

    2005-07-01

    Syncrude Canada Ltd., the world's largest producer of crude oil from oil sands, has made upgrades over a seven-year period to its water recycling process, resulting in more heat recovered at the preheaters in its oil sands operations. The preheaters are the key to the recycling process water system. The incentive to optimize heat recovery at the preheaters was to reduce the amount of natural gas required to heat the water used to extract bitumen from the oil sands. The second objective was to lower costs spent on new equipment to heat the water. Syncrude operators attended workshops offered by the Office of Energy Efficiency at Natural Resources Canada to learn the value of monitoring and cleaning the process-water system to recover as much lost heat as possible. This paper presented a project profile and the approach used to optimize the system, beginning with the installation of twisted-tube heat exchangers in 1997, followed by the installation of a larger pump impeller in 1998 which increased the pumping capacity. In 2003, the target outlet temperature for the preheaters was set at 20 degrees C. This paper also described the challenges regarding water temperature, water pressure and maintenance issues. The innovative solutions used to overcome them have lead to energy costs savings of about $60,000 per month. Syncrude is currently exploring whether water can be preheated higher than 20 degrees C. 2 figs.

  15. 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

    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

  1. 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. 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

  8. 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)

  10. 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)

    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

  5. 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

The ultimate choice of methods, materials, and designs will depend on the site chosen, availability, cost, and practicality. AECL has submitted the Environmental Impact Statement (EIS) on the concept for review by the Environmental Assessment Panel appointed by the federal Minister of the Environment. Three reasons for implementing the concept if accepted are as follows: to show environmental leadership by reducing the burden on future generation, to foster public confidence in nuclear energy, and to forestall 'inaction by default'. 19 refs

  13. Zero-point energy of ultracold atoms

    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.

  20. Atomic Interferometry Test of Dark Energy

    CERN Document Server

    Brax, Philippe

    2016-01-01

    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.

  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.

  3. The industrial development of atomic energy

    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

  4. Constitutionality of the Atomic Energy Act

    International Nuclear Information System (INIS)

    Roma locuta, causa finita. 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.

    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).

    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.

Consequently, there are two kinds of CH bonds of slightly different lengths. The bond energies account for the resonance energy.

  13. 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

    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.

    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.

  6. The geochemistry, age, and origin of groundwater in a mafic pluton, East Bull Lake, Ontario, Canada

    International Nuclear Information System (INIS)

    Atomic Energy of Canada Ltd. (AECL) is conducting geoscience investigations of several plutons in Canada's Precambrian Shield as part of the Canadian Nuclear Fuel Waste Management Program, to determine whether such rock masses are suitable for the safe disposal of nuclear fuel waste. The East Bull Lake (EBL) gabbro-anorthosite layered complex is unique in this program as it is the only mafic pluton in which hydrogeological and hydrogeochemical studies have been conducted. These results can be compared with those of similar studies of granitic rocks which have been investigated more extensively. During the period, 1983-85, hydrogeological testing and hydrochemical sampling were conducted by the National Hydrology Research Institute of Environment Canada and AECL in boreholes drilled to depths of up to 850 m into the EBL pluton (Raven et al., 1987). This paper discusses the hydrogeochemistry of the pluton and identifies the major rock-water interactions controlling the chemistry. The spatial variability in chemistry will be shown to be related to the nature of the groundwater flow systems present at this site. The ages and origins of the groundwaters and their solutes are inferred from isotopic analyses

    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.

    We study three-body recombination of Ba$^+$ + Rb + Rb in the mK regime where a single $^{138}$Ba$^{+}$ ion in a Paul trap is immersed into a cloud of ultracold $^{87}$Rb atoms. We measure the energy dependence of the three-body rate coefficient $k_3$ and compare the results to the theoretical prediction, $k_3 \\propto E_{\\textrm{col}}^{-3/4}$ where $E_{\\textrm{col}}$ is the collision energy. We find agreement if we assume that the non-thermal ion energy distribution is determined by at least two different micro-motion induced energy scales.

  10. 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

  11. Opportunities in Canada's growing wind energy industry

    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

  15. 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.)

    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)

    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.

  11. 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)

    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.)

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

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

    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.

  13. Canada's disposal concept

    International Nuclear Information System (INIS)

    A concept for the safe and permanent disposal of nuclear fuel wastes from Canada's CANDU reactors has been developed by Atomic Energy of Canada Ltd. (AECL). The waste would be placed in an engineered disposal vault 500 to 1000 m below the surface in plutonic rock of the Canadian Shield. The multiple barriers to retain the waste and retard the release of radioactivity would be the waste form, the containers, buffer and backfill, and the rock overlying the vault. Numerous research programmes have been carried out to develop the technology for the concept. These include work on materials corrosion and failure mechanisms to assess the performance of the used fuel containers. Predictive modelling has shown that more than 97% of ASTM Grade 2 titanium containers will retain their integrity, even under pessimistic assumptions, for 1200-6000 years after emplacement, and even longer times may be achieved with other grades of titanium or copper. Other research has been aimed at vault sealing, at site characterization for an underground research laboratory and at the development of a methodology for assessing radiological and environmental effects after closure of the facility. A review of the safety and environmental impacts of the concept is now being carried out by an independent panel appointed by the government. (2 figures, 3 references) (UK)

  15. 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.)

    1999-01-01

    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.

  20. 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

  3. Atomic energy law in the Federal Republic of Germany

    International Nuclear Information System (INIS)

    Atomic Energy Law, presenting itself 18 years after the Atomic Law (AtG) having taken effect in the Federal Republic of Germany, has developed considerably during the past three years which was also due to the controversy between supporters and opponents of nuclear energy becoming more intensive. In order to gain their ends both parties refer to the AtG and expect both the executive and legislative power to follow their interpretation of the laws. The reason for this lies mainly in the latitude of evaluating and judging the criteria which the law has granted its users, especially the administrative authorities and the courts. Thus political and juridicial fundamental decisions in favour of the peaceful use of nuclear energy might be jeopardized. Therefore all ambignous passages of the law which can be detected by critically evaluating numerous and partly inconsistent decisions of courts, should be eliminated, in particular for reasons of its validity. Also, administration and court should be given concrete standards for rating the application of the law, especially for the assessment and acceptance of the risks rising from the peaceful use of nuclear energy.

  6. 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

  7. High-energy atomic physics

    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...

  10. Change of Energy of the Cubic Subnanocluster of Iron Under Influence of Interstitial and Substitutional Atoms.

    Nedolya, Anatoliy V; Bondarenko, Natalya V

    2016-12-01

    Energy change of an iron face-centred cubic subnanocluster was evaluated using molecular mechanics method depending on the position of a carbon interstitial atom and substitutional atoms of nickel. Calculations of all possible positions of impurity atoms show that the energy change of the system are discrete and at certain positions of the atoms are close to continuous.In terms of energy, when all impurity atoms are on the same edge of an atomic cluster, their positions are more advantageous. The presence of nickel atoms on the edge of a cubic cluster resulted in decrease of potential barrier for a carbon atom and decrease in energy in the whole cluster. A similar drift of a carbon atom from central octahedral interstitial site to the surface in the direction occurred under the influence of surface factors.Such configuration corresponds to decreasing symmetry and increasing the number of possible energy states of a subnanocluster, and it corresponds to the condition of spontaneous crystallization process in an isolated system.Taking into account accidental positions of the nickel atom in the iron cluster, such behaviour of the carbon atom can explain the mechanism of growth of a new phase and formation of new clusters in the presence of other kind of atoms because of surface influence.

  12. 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. Low-energy scattering of electrons by atomic oxygen

    International Nuclear Information System (INIS)

    The method of polarized pseudostates has been used to calculate cross sections for the elastic scattering of electrons by atomic oxygen. These pseudostates are added to the close-coupling expansion to give a polarization potential in agreement with experimental values of polarizability. The resulting elastic cross sections are in good agreement with other theoretical calculations as well as with experiment for energies up to 10 eV. The reactance matrices obtained in this calculation have been used to calculate collision strengths for fine-structure transitions in the ground-state 3P term for electron temperatures above 5000 degree K

    Britain was the first country to exploit atomic energy on a large scale, and at its peak in the mid-1960s, it had generated more electricity from nuclear power than the rest of the world combined.The civil atomic energy programme grew out of the military programme which produced plutonium for atomic weapons. In 1956, Calder Hall power station was opened by the Queen. The very next year, one of the early Windscale reactors caught fire and the world's first major nuclear accident occurred.The civil programme ran into further difficulty in the mid-1960s and as a consequence of procrastination in

  19. Butterfly Species Richness Patterns in Canada: Energy, Heterogeneity, and the Potential Consequences of Climate Change

    Directory of Open Access Journals (Sweden)

    Jeremy T. Kerr

    2001-06-01

    Full Text Available The distributions of most pollinator species are poorly documented despite their importance in providing ecosystem services. While these and other organisms are threatened by many aspects of the human enterprise, anthropogenic climate change is potentially the most severe threat to pollinator biodiversity. Mounting evidence demonstrates that there have already been biotic responses to the relatively small climate changes that have occurred this century. These include wholesale shifts of relatively well-documented butterfly and bird species in Europe and North America. Although studies of such phenomena are supported by circumstantial evidence, their findings are also consistent with predictions derived from current models of spatial patterns of species richness. Using new GIS methods that are highly precise and accurate, I document spatial patterns of Canadian butterfly diversity. These are strongly related to contemporary climate and particularly to potential evapotranspiration. An even more noteworthy finding is the fact that, for the first time, habitat heterogeneity, measured as the number of land cover types in each study unit, is proven to be an equally strong predictor of butterfly richness in a region where energy alone was thought to be the best predictor of diversity. Although previous studies reveal similar relationships between energy and diversity, they fail to detect the powerful link between richness and habitat heterogeneity. The butterflies of Canada provide a superb baseline for studying the effects of climate on contemporary patterns of species richness and comprise the only complete pollinator taxon for which this sort of analysis is currently possible.

  4. 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

    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

Discussions were arranged by the Canadian Fusion-Fuels Technology Project near Toronto and covered all aspects of tritium technology but especially radiological protection. Visits included the CFFTP Centre, Pickering Nuclear Generating Section, Ontario Hydro's Head Office, Safety Services Department and Research Division, Scintrex Ltd (tritium instrument manufacturers) and the Atomic Energy of Canada (AECL) Chalk River Nuclear laboratories (CRNL). There are clearly many areas for the use of Canadian Technology in Europe, particularly with CRNL and Scintrex on the development of 3H2/3H2O discriminating monitors. There is some doubt whether these development will be in time for applications at the JET laboratory and the JRC at ISPRA but this collaboration will be pursued. (author)

    We performed embedded atom method calculations on surface energies and unstable stacking fault energies for a series of intermetallics for which interatomic potentials of the embedded atom type have recently been developed. These results were analyzed and applied to the prediction of relative ductility of these materials using the various current theories. Series of alloys with the B2 ordered structure were studied, and the results were compared to those in pure body-centered cubic (bcc) Fe. Ordered compounds with L1{sub 2} and L1{sub 0} structures based on the face-centered cubic (fcc) lattice were also studied. It was found that there is a correlation between the values of the antiphase boundary (APB) energies in B2 alloys and their unstackable stacking fault energies. Materials with higher APB energies tend to have higher unstable stacking fault energies, leading to an increased tendency to brittle fracture. {copyright} {ital 1997 Materials Research Society.}

  8. Atomic Energy Law and the right of life and health

    International Nuclear Information System (INIS)

    The paper is a review of the dissertation submitted for the certificate of habilitation by Professor Degenhardt belonging to the series of publications 'Law-Technology-Economy'. Beneath the somewhat- summary title Kernenergierecht (atomic energy law) there is hidden the first systematic treatment of all the fundamental questions of constitutional law, of general law and naturally of the special nuclear administrative law and of the law of administrative proceedings which occurred in decisions of different administrative courts concerning several nuclear power plants in the Federal Republic of Germany. Despite the plainness of his own viewpoint this impressive, sophisticated and balanced inventory is certainly welcome to all interested people and it is very useful for the further treatment of these problems.

    2016-03-01

    The theories developed by Bohr and Mottelson have inspired much of the world-wide experimental investigation into the structure of the atomic nucleus. On the occasion of the 40th anniversary of the awarding of their Nobel prize, we reflect on some of the experimental developments made in understanding the structure of nuclei. We have chosen to focus on experiments performed in Canada, or having strong ties to Canada, and the work included here spans virtually the whole of the second half of the 20th century. The 8π Spectrometer, which figures prominently in this story, was a novel departure for funding science in Canada that involved an intimate collaboration between a Crown Corporation (Atomic Energy of Canada Ltd) and University research, and enabled many of the insights discussed here.

  11. Higher Ionization Energies of Atoms in Density Functional Theory

    CERN Document Server

    Argaman, Uri; Kraisler, Eli

    2014-01-01

    Density functional theory (DFT) is an exact alternative formulation of quantum mechanics, in which it is possible to calculate the total energy, the spin and the charge density of many-electron systems in the ground state. In practice, it is necessary to use uncontrolled approximations that can mainly be verified against experimental data. Atoms and ions are simple systems, where the approximations of DFT can be easily tested. We have calculated within DFT the total energies, spin and higher ionization energies of all the ions of elements with 1 $\\leq$ Z $\\leq$ 29. We find the calculations in close agreement with experiment, with an error of typically less than ca. 1% for 1 $\\leq$ Z $\\leq$ 29. Surprisingly, the error depends on the electronic configuration of the ion in both local spin density approximation (LSDA) and Perdew-Burke-Ernzerhof general gradient approximation (PBE-GGA) and independent of both self-interaction correction (SIC) and relativistic corrections. Larger errors are found for systems in whi...

    The Atomic Energy Corporation of South Africa Ltd (AEC) owns and operates the 20 MW research reactor, SAFARI-1. Utilisation of the reactor has in recent years changed from research and materials testing to the production of isotopes. The most important breakthrough achieved in recent years is the production of high quality fission 99Mo. This has been produced routinely since April 1993 and supplied to clients across the world. A capability for the reliable production of 1000 Ci of 99Mo per week (calibrated for six days after production) has been proven. The AEC has also established facilities to produce its own 99mTc generators together with a most of radiopharmaceutical kits for diagnostic nuclear medicine purposes. The production of {sup 153}Sm and {sup 131}I (tellurium oxide route) has been operational for many years. Applications include therapeutic radiopharmaceuticals such as {sup 153}Sm-EDTMP for bone cancer pain palliation, {sup 13`}I-Lipiodol for liver cancer and {sup 131}I capsules for thyroid treatment. Facilities for the production of other isotopes such as {sup 131}I (from fission), {sup 32}P and {sup 35}S are in various stages of completion. Extensive analytical methods and equipment have been developed and are routinely used to certify the quality of exported isotopes. Irradiation and encapsulation of {sup 192}Ir is also performed routinely at the AEC. Modern facilities allow for the production of isotopes such as {sup 131}Ba and {sup 140}La on an ad hoc basis. Quality assurance procedures based on ISO9000 were developed for all aspects of the production of the various isotopes. Documentation, such as Drug Master Files, required by authorities in various countries has also been submitted and accepted 15 refs., 1 tab., 2 figs.

  17. The effect of deposition energy of energetic atoms on the growth and structure of ultrathin amorphous carbon films studied by molecular dynamics simulations

    KAUST Repository

    Wang, N

    2014-05-16

    The growth and structure of ultrathin amorphous carbon films was investigated by molecular dynamics simulations. The second-generation reactive-empirical-bond-order potential was used to model atomic interactions. Films with different structures were simulated by varying the deposition energy of carbon atoms in the range of 1-120 eV. Intrinsic film characteristics (e.g. density and internal stress) were determined after the system reached equilibrium. Short- and intermediate-range carbon atom ordering is examined in the context of atomic hybridization and ring connectivity simulation results. It is shown that relatively high deposition energy (i.e., 80 eV) yields a multilayer film structure consisting of an intermixing layer, bulk film and surface layer, consistent with the classical subplantation model. The highest film density (3.3 g cm-3), sp3 fraction (∼43%), and intermediate-range carbon atom ordering correspond to a deposition energy of ∼80 eV, which is in good agreement with experimental findings. © 2014 IOP Publishing Ltd.

    1990-01-01

    The reaction efficiency of several polymeric materials with thermal-energy (0.04 eV translational energy), ground-state (O3P) oxygen atoms was determined by exposing the materials to a room temperature gas containing a known concentration of atomic oxygen. The reaction efficiency measurements were conducted in two flowing afterglow systems of different configuration. Atomic oxygen concentration measurements, flow, transport and surface dose analysis is presented in this paper. The measured reaction efficiencies of Kapton, Mylar, polyethylene, D4-polyethylene and Tedlar are .001 to .0001 those determined with high-energy ground-state oxygen atoms in low earth orbit or in a high-velocity atom beam. D4-polyethylene exhibits a large kinetic isotope effect with atomic oxygen at thermal but not hyperthermal atom energies.

    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

    We introduce a machine learning model to predict atomization energies of a diverse set of organic molecules, based on nuclear charges and atomic positions only. The problem of solving the molecular Schr\\"odinger equation is mapped onto a non-linear statistical regression problem of reduced complexity. Regression models are trained on and compared to atomization energies computed with hybrid density-functional theory. Cross-validation over more than seven thousand small organic molecules yields a mean absolute error of ~10 kcal/mol. Applicability is demonstrated for the prediction of molecular atomization potential energy curves.

    Visible emission spectra were acquired from neutral atoms sputtered by 35–60 keV Kr{sup +} ions from a polycrystalline tungsten surface. Mean velocities of excited tungsten atoms in seven different 6p states were also obtained via the dependence of photon intensities on the distance from the surface. The average velocities parallel to the surface normal varied by factors of 2–4 for atoms in the different 6p energy levels. However, they were almost independent of the incident ion kinetic energy. The 6p-level energy dependence indicated that the velocities of the excited atoms were determined by inelastic processes that involve resonant charge exchange.

  20. 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

    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.

  2. Report on the use of programmable digital computers in the shutdown systems of the Darlington G.S

    International Nuclear Information System (INIS)

    This report by the Advisory Committee on Nuclear Safety (ACNS) considers the use of large, programmable computers in the shutdown system at the planned Darlington Generating Station. After a review of the documents submitted to the Atomic Energy Control Board (AECB) by Atomic Energy of Canada Ltd. Engineering Company in support of gaining AECB's agreement in principle to such a system, the ACNS concludes that no fundamental principle will be challenged by the introduction of computer technology into safety systems. It cautions, however, that the AECB should ensure that existing principles, particularly those of independence and redundancy, will not be compromised in the application

  3. 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

    2016-09-01

    The structure of the rate of variation of the atomic energy for an arbitrary stationary motion of the atom in interaction with a quantum electromagnetic field is investigated. Our main purpose is to rewrite the formalism in Zhu et al. (Phys Rev D 73:107501, 2006) and to deduce the general expressions of the Einstein A coefficients of an atom on an arbitrary stationary trajectory. The total rate of change of the energy and Einstein coefficients of the atom near a plate with finite temperature or acceleration are also investigated.

    2001-01-01

    We have calculated the energy spectra of one- and two-electron atoms (ions) centered in an impenetrable spherical box by variational method with B-splines as basis functions. Accurate results are obtained for both large and small radii of confinement. The critical box radius of confined hydrogen atom is also calculated to show the usefulness of our method. A partial energy degeneracy in confined hydrogen atom is found when the radius of spherical box is equal to the distance at which a node of single-node wavefunctions of free hydrogen atom is located.

  7. Theoretical study of atoms by the electronic kinetic energy density and stress tensor density

    CERN Document Server

    Nozaki, Hiroo; Tachibana, Akitomo

    2016-01-01

    We analyze the electronic structure of atoms in the first, second and third periods using the electronic kinetic energy density and stress tensor density, which are local quantities motivated by quantum field theoretic consideration, specifically the rigged quantum electrodynamics. We compute the zero surfaces of the electronic kinetic energy density, which we call the electronic interfaces, of the atoms. We find that their sizes exhibit clear periodicity and are comparable to the conventional atomic and ionic radii. We also compute the electronic stress tensor density and its divergence, tension density, of the atoms, and discuss how their electronic structures are characterized by them.

  13. 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

  16. The Russian Federation's Ministry of Atomic Energy: Programs and Developments

    International Nuclear Information System (INIS)

    This paper reviews select programs driving the Ministry of Atomic Energy of the Russian Federation's (Minatom) efforts to raise funds, comments on their potential viability, and highlights areas likely to be of particular concern for the US over the next three to five years. The paper's findings are: (1) Despite numerous cabinet displacements throughout the Yeltsin administration, Yevgeny Adamov was reappointed Minister on four occasions. With Boris Yeltsin's January 1, 2000 resignation, Adamov's long-term position as the head of the Ministry is more tenuous, but he will likely retain his position until at least the March 2000 elections. Acting President Vladimir Putin is unlikely to reorganize his cabinet prior to that date and there are no signs that Putin is dissatisfied with Adamov's leadership of Minatom. (2) Adamov's chief priorities are downsizing Minatom's defense sector, increasing the oversight of subsidiary bodies by the central bureaucracy and consolidating commercial elements of the Ministry within an umbrella organization called Atomprom. (3) Viktor Mikhaylov, Adamov's predecessor and critic of his reform efforts, has been relieved of his duties as First Deputy Minister. While he retains his positions as Chief of the Science Councils and Chief Scientist at Arzamas-16, his influence on Minatom's direction is greatly diminished. Adamov will likely continue his efforts to further marginalize Mikhaylov in the coming year. (4) Securing extra-budgetary sources of income continues to be the major factor guiding Minatom's international business dealings. The Ministry will continue to aggressively promote the sale of nuclear technology abroad, often to countries with questionable nonproliferation commitments. (5) Given the financial difficulties in Russia and Minatom's client states, however, few nuclear development programs will come to fruition for a number of years, if ever. Nevertheless, certain peaceful nuclear cooperation agreements should be carefully

  17. Theory of ion-atom collisions at high energy, I

    International Nuclear Information System (INIS)

    Electron capture process by an ion from a neutral atom is one of the fundamental problems in the theory of atomic collision physics. Here a brief review is given mainly on the processes of non-radiative and radiative electron capture (charge transfer and REC). The main mechanism which govern the charge transfer process is introduced and the characteristic feature which is predicted by the theory is explained. As for the radiative electron capture process, after introducting the present theories, the full-quantum mechanical theoretical treatment is introduced. The theory leads a result which includes some inconsistency with formulae obtained by guage transformation. The relativistic quantum mechanical treatment is being tried in order to remove this inconsistency. The some results including mass and velocity dependence are reported and discussed. (author)

Many technical details of recent work were reported and the results of work already published were confirmed and amplified. It became quite clear at the Conference that atomic energy has now reached the industrial stage in various countries. The Conference can thus be seen as a sort of landmark marking the beginning of the era of nuclear power

  19. ''Further precaution'' in Atomic Energy Law? On unconstitutionality of paragraph 7d AtG

    International Nuclear Information System (INIS)

    On 1st January 2011 the new paragraph 7d of the Atomic Energy Act became operative with the 12th Modification Law according to the Atomic Energy Law. This new paragraph introduces a new category of the nuclear-legal prevention of damage. The contribution under consideration examines how this new regulation for further precautionary actions against risks is to be understood within the existing regulations for permission and retrofitting of nuclear power plants and within the acknowledged dogmatics of the Atomic Energy Act. In addition it is examined whether this understanding of the regulations agrees with the jurisdiction of the constitutional court according to the nuclear legal protection obligations.

    Matveev, V. I.; Sidorov, D. B.

    2007-07-01

    A nonperturbatve theory of energy losses of fast heavy multiply charged structural ions in collisions with neutral complex atoms is elaborated with allowance for simultaneous excitations of ionic and atomic electron shells. Formulas for the effective deceleration that are similar to the well-known Bethe-Bloch formulas are derived. By way of example, the energy lost by partially stripped U q+ ions (10 ≤ q ≤ 70) colliding with argon atoms and also the energy lost by Au, Pb, and Bi ions colliding with various targets are calculated. The results of calculation are compared with experimental data.

  1. 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.)

    Using the "Pseudo-invariant eigen-operator" method we find the energy-gap of the Jaynes-Cummings Hamiltonian model of an atom-cavity system. This model takes the atomic centre-of-mass motion into account. The supersymmetric structure is involved in the Hamiltonian of an atom-cavity system. By selecting suitable supersymmetric generators and using supersymmetric transformation the Hamiltonian is diagonalized and energy eigenvectors are obtained.

    International Nuclear Information System (INIS)

    The perception of the nuclear energy of journalist of the Cordoba city and of the member of the legislative body of the Province was investigated. In general a high degree of ignorance on nuclear energy and its uses was found. The majority of them considers nuclear energy a great danger for the society and describes it as a potential damage for health and environment. Little is known about medical applications, food irradiation, etc. As a consequence nuclear energy has no priority in journalist and lawmakers agendas. (author)

The results are of interest for future hadronic atom experiments.

  5. Present state of research and development of atomic energy in five Asian countries

    International Nuclear Information System (INIS)

    The survey group for Asian atomic energy cooperation was dispatched by the Japanese government, and toured Philippines, Indonesia, Malaysia, Thailand and Bangladesh from September 7 to 19, 1980. The present state of atomic energy development and the energy situation in respective countries were surveyed through the exchange of opinion and the inspection of related facilities. The Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology was concluded in June, 1972, and 12 countries have participated in it. It was impressive that respective countries have the peculiar energy policies corresponding to their objective conditions. They regard atomic energy as the important substitute energy for petroleum, but the fear about the safety of atomic energy and the movement against nuclear power generation have been growing considerably. The research and development on atomic energy are carried out very actively in respective countries, and the construction of large-scale research centers was commenced in Indonesia, Malaysia and Bangladesh. Research reactors have been operated in Philippines, Indonesia and Thailand since about 20 years ago, and the utilization of radioisotopes and radiation has been studied. The cooperation of Japan with these countries is far behind that of other advanced countries. (Kako, I.)

    A new approach for computing the atom-in-molecule [quantum theory of atoms in molecule (QTAIM)] energies in Kohn-Sham density-functional theory is presented and tested by computing QTAIM energies for a set of representative molecules. In the new approach, the contribution for the correlation-kinetic energy (T(c)) is computed using the density-functional theory virial relation. Based on our calculations, it is shown that the conventional approach where atomic energies are computed using only the noninteracting part of the kinetic energy might be in error by hundreds of kJ/mol.

  8. Manhattan Project redux: Canada and the first atomic weapons

    International Nuclear Information System (INIS)

    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)

  13. 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

  16. Canada's constitutional separation of (wind) power

    International Nuclear Information System (INIS)

    This paper investigates the impact that a federal government structure has on strategic selection of renewable energy policy instruments. The context for this study centers on wind power development in Canada. Canada is a nation that is blessed by all the attributes necessary to catalyze global leadership in installed wind power capacity. Unfortunately, the constitutional separation of powers that underpins Canada's federal system impedes the creation of a national wind power development strategy because Canada's provinces have constitutional authority over electricity governance. The insights gleaned from the case study are used to develop a conceptual framework for understanding the impact that federal structure has on policy instrument selection and efficacy under areas of federal, regional and concurrent policy jurisdiction. Finally, this framework is re-applied to identify specific approaches the Canadian federal government could take to resolve what currently amounts to be a fragmented, ineffective approach to wind power development planning.

  17. Self-energy and interaction energy of stacking fault in fcc metals calculated by embedded-atom method

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The stacking fault energies of five fcc metals (Cu, Ag, Au, Ni and Al) with various quantivalences have been calculated by embedded-atom method (EAM). It indicated that the stacking fault energy is mainly determined by the metallic bond-energy and the lattice constant. Thus, monovalent fcc metals should have different stacking fault energies, contrary to Attree's conclusion. The interaction energy between stacking faults one {111} layer apart in a fcc metal is found to be 1/40-1/250 of its self-energy, while it becomes zero when the two stacking faults are two layers apart. The twin energy is just half of the energy of intrinsic stacking fault energy without the consideration of lattice relax-ation and the energy of a single intrinsic stacking fault is almost the same as that of extrinsic stacking fault, which are consistent with the results from the calculation of Lennard-Jones force between atoms, but differ from Attree's result.

  18. On the energy levels of the hydrogen atom

    CERN Document Server

    Fewster, C J

    1993-01-01

    We re-examine the justification for the imposition of regular boundary conditions on the wavefunction at the Coulomb singularity in the treatment of the hydrogen atom in non-relativistic quantum mechanics. We show that the issue of the correct boundary conditions is not independent of the physical structure of the proton. Under the physically reasonable assumption that the finite size and structure of the proton can be represented as a positive correction to the Coulomb potential, we give a justification for the regular boundary condition, which, in contrast to the usual treatments, is physically motivated and mathematically rigorous. We also describe how irregular boundary conditions can be used to model non-positive corrections to the Coulomb potential.

    Banks, Bruce A.; Rutledge, Sharon K.; Degroh, Kim K.; Stidham, Curtis R.; Gebauer, Linda; Lamoreaux, Cynthia M.

    1995-01-01

    The durability evaluation of protected polymers intended for use in low Earth orbit (LEO) has necessitated the use of large-area, high-fluence, atomic oxygen exposure systems. Two thermal energy atomic oxygen exposure systems which are frequently used for such evaluations are radio frequency (RF) plasma ashers and electron cyclotron resonance plasma sources. Plasma source testing practices such as ample preparation, effective fluence prediction, atomic oxygen flux determination, erosion measurement, operational considerations, and erosion yield measurements are presented. Issues which influence the prediction of in-space durability based on ground laboratory thermal energy plasma system testing are also addressed.

  20. Effective atomic numbers for photon energy absorption of some low-Z substances of dosimetric interest

    International Nuclear Information System (INIS)

    Effective atomic numbers for photon energy absorption (ZPEAeff) and effective atomic numbers for photon interaction (ZPIeff) of some low-Z substances of dosimetric interest such as A-150 tissue-equivalent plastic (A150TEP), alanine, bakelite, Gafchromic sensor (GS), plastic scintillator (PS), polyethylene, mylar, polystyrene, perspex, radiochromic dye film nylon base (RDF : NB), tissue-equivalent gas-methane based (TEG : MB) and tissue-equivalent gas-propane based (TEG : PB) have been calculated by a direct method in the energy region of 1 keV-20 MeV. Experimental mass attenuation coefficients and ZPIeff of some of these substances at selected photon energies of 26.34, 33.2, and 59.54 keV have been obtained and compared with theoretical values. The ZPEAeff and ZPIeff values steadily increases up to 6-15 keV, and then they steadily decrease up to 600-1500 keV for all the substances studied. From 1.5 MeV, the values increases with increase in energy up to 20 MeV. Significant differences up to 33.68% exist between ZPIeff and the ZPEAeff in the energy region of 10-150 keV. The single effective atomic numbers obtained using the program XMuDat (ZXMUDATeff ) are found to be significantly higher compared to those of ZPEAeff and ZPIeff values in the entire energy of interest for all the substances studied. The directly calculated ZPEAeff and ZPIeff values vary with energy compared to the energy-independent effective atomic numbers predicted by various theoretical expressions. The effects of absorption edges on effective atomic numbers and their variation with photon energy and the possibility of defining two set values of effective atomic numbers below the absorption edges of elements present in the composite substances are discussed

    Reflection electron energy loss spectra from some insulating materials (CaCO{sub 3}, Li{sub 2}CO{sub 3}, and SiO{sub 2}) taken at relatively high incoming electron energies (5–40 keV) are analyzed. Here, one is bulk sensitive and a well-defined onset of inelastic excitations is observed from which one can infer the value of the band gap. An estimate of the band gap was obtained by fitting the spectra with a procedure that includes the recoil shift and recoil broadening affecting these measurements. The width of the elastic peak is directly connected to the mean kinetic energy of the atom in the material (Doppler broadening). The experimentally obtained mean kinetic energies of the O, C, Li, Ca, and Si atoms are compared with the calculated ones, and good agreement is found, especially if the effect of multiple scattering is taken into account. It is demonstrated experimentally that the onset of the inelastic excitation is also affected by Doppler broadening. Aided by this understanding, we can obtain a good fit of the elastic peak and the onset of inelastic excitations. For SiO{sub 2}, good agreement is obtained with the well-established value of the band gap (8.9 eV) only if it is assumed that the intensity near the edge scales as (E − E{sub gap}){sup 1.5}. For CaCO{sub 3}, the band gap obtained here (7 eV) is about 1 eV larger than the previous experimental value, whereas the value for Li{sub 2}CO{sub 3} (7.5 eV) is the first experimental estimate.

    2008-01-15

    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

  4. Atom probe tomography simulations and density functional theory calculations of bonding energies in Cu3Au

    KAUST Repository

    Boll, Torben

    2012-10-01

    In this article the Cu-Au binding energy in Cu3Au is determined by comparing experimental atom probe tomography (APT) results to simulations. The resulting bonding energy is supported by density functional theory calculations. The APT simulations are based on the Müller-Schottky equation, which is modified to include different atomic neighborhoods and their characteristic bonds. The local environment is considered up to the fifth next nearest neighbors. To compare the experimental with simulated APT data, the AtomVicinity algorithm, which provides statistical information about the positions of the neighboring atoms, is applied. The quality of this information is influenced by the field evaporation behavior of the different species, which is connected to the bonding energies. © Microscopy Society of America 2012.

  5. Submission to the Government of Canada, in the national interest : a Canadian oil and natural gas strategy for a North American energy market

    International Nuclear Information System (INIS)

    The Canadian Association of Petroleum Producers (CAPP) sees a need for more federal emphasis on six main principles regarding an energy strategy that will ensure that Canada's economy and citizens benefit from free access to North American markets. The development of energy resources must be done in a manner that meets North American demand for energy supplies, addresses high prices by increasing supply and enhances Canada's role as a reliable energy supplier. CAPP has proposed the following six main principles for an energy strategy: (1) development of market oriented policies, (2) ensure regulatory effectiveness, (3) promote greater industry competitiveness, (4) create more jobs for stronger communities, (5) foster the development of technological innovation, and (6) use energy wisely and efficiently. The key components of each principle were described in detail, along with their benefits to the Canadian economy

    We observe strong energy-dependent quantum defects in the scaled-energy Stark spectra for |M|=1 Rydberg states of barium atoms at three scaled energies: ε= -2.000, ε= -2.500 and ε=-3.000. In an attempt to explain the observations, theoretical calculations of closed orbit theory based on a model potential including core effect are performed for non-hydrogenic atoms. While such a potential has been uniformly successful for alkali atoms with a single valence electron, it fails to match experimental results for barium atoms in the 6snp Rydberg states with two valence electrons. Our study points out that this discrepancy is due to the strong perturbation from the 5d8p state, which voids the simple approximation for constant quantum defects of principle quantum number n.

  7. 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

  8. Direct measurement of desorption and diffusion energies of O and N atoms physisorbed on amorphous surfaces

    Minissale, Marco; Dulieu, François

    2016-01-01

    Physisorbed atoms on the surface of interstellar dust grains play a central role in solid state astrochemistry. Their surface reactivity is one source of the observed molecular complexity in space. In experimental astrophysics, the high reactivity of atoms also constitutes an obstacle to measuring two of the fundamental properties in surface physics, namely desorption and diffusion energies, and so far direct measurements are non-existent for O and N atoms. We investigated the diffusion and desorption processes of O and N atoms on cold surfaces in order to give boundary conditions to astrochemical models. Here we propose a new technique for directly measuring the N- and O-atom mass signals. Including the experimental results in a simple model allows us to almost directly derive the desorption and diffusion barriers of N atoms on amorphous solid water ice (ASW) and O atoms on ASW and oxidized graphite. We find a strong constraint on the values of desorption and thermal diffusion energy barriers. The measured b...

    In order to understand the AEC in its present form and its strategic positioning for the next century, it is essential that cognisance be taken of its evolution over the past 40 years and, in particular, also the external forces which triggered major strategic re-orientation actions in the past. These resulted in a fundamentally downsized organization (by about 80%) which will in the new millennium be judged on its ability to make nuclear technology available for the needs of a developing country, discharge the nuclear liabilities of the past and commercially exploit its technology base to contribute to national economic growth. The Corporation has a strong programme in isotope applications and nuclear waste management. For the future it is looking forward to develop a Pebble Bed Modular Reactor for safe nuclear energy production. (author)

    Grantz, A.; Hart, P.E.

    2012-01-01

    Reconnaissance seismic reflection data indicate that Canada Basin is a >700,000 sq. km. remnant of the Amerasia Basin of the Arctic Ocean that lies south of the Alpha-Mendeleev Large Igneous Province, which was constructed across the northern part of the Amerasia Basin between about 127 and 89-83.5 Ma. Canada Basin was filled by Early Jurassic to Holocene detritus from the Beaufort-Mackenzie Deltaic System, which drains the northern third of interior North America, with sizable contributions from Alaska and Northwest Canada. The basin contains roughly 5 or 6 million cubic km of sediment. Three fourths or more of this volume generates low amplitude seismic reflections, interpreted to represent hemipelagic deposits, which contain lenses to extensive interbeds of moderate amplitude reflections interpreted to represent unconfined turbidite and amalgamated channel deposits.Extrapolation from Arctic Alaska and Northwest Canada suggests that three fourths of the section in Canada Basin is correlative with stratigraphic sequences in these areas that contain intervals of hydrocarbon source rocks. In addition, worldwide heat flow averages suggest that about two thirds of Canada Basin lies in the oil or gas windows. Structural, stratigraphic and combined structural and stratigraphic features of local to regional occurrence offer exploration targets in Canada Basin, and at least one of these contains bright spots. However, deep water (to almost 4000 m), remoteness from harbors and markets, and thick accumulations of seasonal to permanent sea ice (until its possible removal by global warming later this century) will require the discovery of very large deposits for commercial success in most parts of Canada Basin. ?? 2011 Elsevier Ltd.

    International Nuclear Information System (INIS)

    The information processing using computers has been carried out in the field of atomic energy science internationally since early period, and CINDA and NEUDADA, which are the accumulation of the nuclear data on neutrons, and INIS for the search of literatures are the examples. In Japan, the Japan Atomic Energy Research Institute has functioned as the center for collecting, evaluating and distributing the international informations on atomic energy. In universities, various researcher groups have endeavored to make and utilize the data bases with the advance of functions of large computer centers. In the future plan of the Kyoto University Reactor Research Institute, the establishment of Atomic Energy Science Information Center is planned. In order to discuss the concept for this and refer to the state of activities in other fields, the short period study meeting was helt in 1979, and the special study meeting on the on-line processing of searching the scientific informations and literatures on atomic energy was established in 1980. This report summarizes the results of studies and investigations published in this special study meeting. The abstracts of five papers on various data bases are given. (Kako, I.)

    2011-01-01

    Full Text Available The sustainability of a large-scale hydrogen production system is assessed qualitatively. The system uses solid fuels and aims to increase the sustainability of the energy system in Canada through the use of alternative energy forms. The system involves significant technology integration, with various energy conversion processes (e.g., gasification, chemical looping combustion, anaerobic digestion, combustion power cycles-electrolysis and solar-thermal convertors interconnected to increase the utilization of solid fuels as much as feasible in a sustainable manner within cost, environmental and other constraints. The qualitative analysis involves ten different indicators for each of the three dimensions of sustainability: ecology, sociology and technology, applied to each process in the system and assessed based on a ten-point quality scale. The results indicate that biomasses have better sustainability than coals while newer secondary processes are essential for primary conversion to be sustainable, especially when using coals. Also, new developments in CO2 use (for algae-to-oil and commercial applications and storage will in time help improve sustainability.

  4. Energy considerations in spraying process of a spill-return pressure-swirl atomizer

    International Nuclear Information System (INIS)

    Graphical abstract: - Highlights: • We analyse energy conversion in simplex and spill-return pressure-swirl atomizer. • Inlet (pressure) energy converts into liquid motion with nozzle efficiency ∼58%. • Kinetic energy of developed spray at closed spill line is ∼33% of the inlet energy. • It consists of energy of droplets (∼2/3) and entrained air (1/3). • Atomization efficiency is <0.3%; it declines with inlet pressure and spill opening. - Abstract: The work focuses on energy conversion during the internal flow, discharge and formation of the spray from a pressure-swirl (PS) atomizer in the simplex as well as spill-return mode. Individual energy forms are described in general and assessed experimentally for a particular PS atomizer and light heating oil as a medium. The PS spray was observed at various loads to investigate the liquid breakup process and the spray characteristics. Spatially resolved diameters and droplet velocities, measured by means of phase-Doppler anemometry, served for estimation of the energy characteristics in the PS spray. The input energy given by the potential energy of the supplied liquid partially converts into the kinetic energy (KE) in the swirling ports with hydraulic loss in per cent scale. Most of the pressure drop is associated with rotational motion in the swirl chamber with total conversion efficiency at the exit orifice ∼58%. The rest of the input energy ends up as friction loss, leaving room for improvement. The overall value (ID32) of the Sauter mean diameter of droplets in the spray, D32, varies with pressure drop Δpl powered to −0.1. The radial profiles of D32 widen with the increase in spill/feed ratio (SFR), but the ID32 remain almost constant within the studied SFR range. The spray KE at closed spill line covers the droplet KE (21–26%) and that of entrained air (10–13%), both moderately varying with Δpl. The specific KEs of both the liquid and air markedly drop down with the spill line opening

    2004-01-01

    The surface energies for 38 surfaces of fcc metals Cu, Ag, Au, Ni, Pd, Pt, Al, Pb, Rh and Ir have been calculated by using the modified embedded-atom method. The results show that, for Cu, Ag, Ni, Al, Pb and Ir, the average values of the surface energies are very close to the polycrystalline experimental data. For all fcc metals, as predicted, the close-packed (111) surface has the lowest surface energy. The surface energies for the other surfaces increase linearly with increasing angle between the surfaces (hkl) and (111). This can be used to estimate the relative values of the surface energy.

    2003-08-26

    The effect of heat-island reduction (HIR) strategies on annual energy savings and peak-power avoidance of the building sector of the Greater Toronto Area is calculated, using an hourly building energy simulation model. Results show that ratepayers could realize potential annual energy savings of over $11M from the effects of HIR strategies. The residential sector accounts for over half (59%) of the total savings, offices 13% and retail stores 28%. Savings from cool roofs are about 20%, shade trees 30%, wind shielding of trees 37%, and ambient cooling by trees and reflective surfaces 12%. These results are preliminary and highly sensitive to the relative price of gas and electricity. Potential annual electricity savings are estimated at about 150GWh and potential peak-power avoidance at 250MW.

  1. Efficiency enhancement of stationary solar energy based power conversion systems in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Sharan, Anand M. [Faculty of Engineering, Memorial University of Newfoundland, St. John' s, Newfoundland (Canada)

    2009-09-15

    This paper presents the optimum energy conversion conditions of stationary photovoltaic panels used for electrical power generation. The results are arrived at after performing calculations for 180 days in a given year at the latitude of St. John's, Newfoundland. The latitude of this city is close to other Canadian major population centers. Various angular orientations of sun's rays on the earth are considered. On a given day, the incident energy flux of sun is resolved into three components, and the conversion efficiency is based on the flux normal to the panels. The efficiency of conversion of the incident energy is measured with respect to a solar tracking process. The numbers of days in a given year are divided into two groups - one between the winter solstice and the spring equinox, and another between the spring equinox and the summer solstice. The results show the existence of two maxima, one for each of the two periods. By setting the panels at each of these maxima, very significant improvement in energy conversion can be achieved.

    2005-03-01

    Details of Syncrude's Effective Reading in Context (ERIC) workplace literacy program were presented as part of a series of case studies addressing best practices in the development of essential skills in the workplace. ERIC was designed to enhance supervisors' key essential skills, including reading comprehension, writing and the ability to deal with organizational changes and technological advances. Due to its success, Syncrude now offers ERIC to all of its employees and has made it available to a variety of businesses and institutions across Canada. ERIC was implemented due to a shortage of skilled workers, and concerns that a lack of essential skills in the workforce was affecting productivity. ERIC is delivered in 2 phases: a curriculum adaptation phase and a pilot workshop phase where the skills of all participants are assessed individually. Participants are given samples of printed materials they regularly encounter in their jobs. They are then assessed on how well they can generalize, synthesize and analyze the material. Program evaluations are reviewed to ensure that participants can transfer learned skills into new areas, including work tasks. It costs between $6000 and $12,000 to adapt ERIC for a specific workplace. Details of instructor training methods and course manuals were presented. Over the past 16 years, 6 large industry partners and 9 educational partners have been involved in the delivery of ERIC, which has been adapted to a variety of settings, including an Aboriginal pre-trades program at Keyano College. It was concluded that the implementation of ERIC in organizations has led to increased productivity and a decrease in work-related incidents. The Syncrude Essential Skills training program has now been expanded to include a math and writing component.

  4. Inquiries about awareness and knowledge of children and pupils on the concept related with atomic energy

    International Nuclear Information System (INIS)

    There is almost no chance to learn about the words (atomic energy), (radioactivity) and (radiation) in the middle and/or high school educations in Japan, because physics is one of the options in the high school curriculum, and 80-90% of students do not like to choose physics. This inquires aim to know the level of their knowledge on energy resources, atomic energy, radioactivity, radiation, and information sources on their related knowledge. Inquiries are made for the middle and high school students in Tokushima and Tsuruga. There are coal power plants in Tokushima, while atomic power plants in Tsuruga. Fossils energy gets the highest points in Tokushima, while Atomic energy gets the highest points in Tsuruga for a present-day energy source. Solar energy sources get the highest point as a promising 21st century energy source in both prefectures, especially for female students. Radioactivity reminds them of words atomic bomb, disease, injury, and harmful, those give very negative images. Radiation reminds them of words roentgen, radiation therapy, x-ray, and hospital use, those designate a sort of plus-image. More than 50 to 60% of them obtained their knowledge from mass media, particularly, television. In addition, less than a few % of them can give any scientific description about these words. As a whole, authors can say that the students have got a certain concept for these words from information of mass media. Meanwhile the school education has approximately no effect on the formation of their concept. Authors are giving some advises and recommendations for the school education and mass media in Japan. (Y.

    2015-05-01

    Full Text Available Corn stover is an abundant agricultural residue that could be used on the farm for heating and crop drying. Ash content and calorific energy of corn grain and six stover components were measured from standing plants during the grain maturing period, between mid-September and mid-November. Ash of stover in standing corn averaged 4.8% in a cool crop heat unit zone (2300–2500 crop heat units (CHU and 7.3% in a warmer zone (2900–3100 CHU. The corn cob had the lowest ash content (average of 2.2% while leaves had the highest content (from 7.7% to 12.6%. In the fall, ash content of mowed and raked stover varied between 5.5% and 11.7%. In the following spring, ash content of stover mowed, raked and baled in May averaged 3.6%. The cob and stalk located below the first ear contained the highest calorific energy with 17.72 MJ·kg−1. Leaves and grain had the lowest energy with an average of 16.99 MJ·kg−1. The stover heat of combustion was estimated at 17.47 MJ·kg−1 in the cool zone and 17.26 MJ·kg−1 in the warm zone. Based on presented results, a partial “cob and husk” harvest system would collect less energy per unit area than total stover harvest (44 vs. 156 GJ·ha−1 and less biomass (2.51 vs. 9.13 t·dry matter (DM·ha−1 but the fuel quality would be considerably higher with a low ash-to-energy ratio (1.45 vs. 4.27 g·MJ−1.

  12. Potential and impacts of renewable energy production from agricultural biomass in Canada

    International Nuclear Information System (INIS)

    Highlights: • This study quantifies the bioenergy production potential in the Canadian agricultural sector. • Two presented scenarios included the mix of market and non-market policy targets and the market-only drivers. • The scenario that used mix of market and policy drivers had the largest impact on the production of bioenergy. • The production of biomass-based ethanol and electricity could cause moderate land use changes up to 0.32 Mha. • Overall, agricultural sector has a considerable potential to generate renewable energy from biomass. - Abstract: Agriculture has the potential to supply considerable amounts of biomass for renewable energy production from dedicated energy crops as well as from crop residues of existing production. Bioenergy production can contribute to the reduction of greenhouse gas (GHG) emissions by using ethanol and biodiesel to displace petroleum-based fuels and through direct burning of biomass to offset coal use for generating electricity. We used the Canadian Economic and Emissions Model for Agriculture to estimate the potential for renewable energy production from biomass, the impacts on agricultural production, land use change and greenhouse gas emissions. We explored two scenarios: the first considers a combination of market incentives and policy mandates (crude oil price of $120 bbl−1; carbon offset price of $50 Mg−1 CO2 equivalent and policy targets of a substitution of 20% of gasoline by biomass-based ethanol; 8% of petroleum diesel by biodiesel and 20% of coal-based electricity by direct biomass combustion), and a second scenario considers only carbon offset market incentives priced at $50 Mg−1 CO2 equivalent. The results show that under the combination of market incentives and policy mandates scenario, the production of biomass-based ethanol and electricity increases considerably and could potentially cause substantial changes in land use practices. Overall, agriculture has considerable potential to generate

  14. Computational model for noncontact atomic force microscopy: energy dissipation of cantilever

    Science.gov (United States)

    2016-09-01

    We propose a computational model for noncontact atomic force microscopy (AFM) in which the atomic force between the cantilever tip and the surface is calculated using a molecular dynamics method, and the macroscopic motion of the cantilever is modeled by an oscillating spring. The movement of atoms in the tip and surface is connected with the oscillating spring using a recently developed coupling method. In this computational model, the oscillation energy is dissipated, as observed in AFM experiments. We attribute this dissipation to the hysteresis and nonconservative properties of the interatomic force that acts between the atoms in the tip and sample surface. The dissipation rate strongly depends on the parameters used in the computational model.

    2009-10-01

    Next to atoms and molecules the powders are the smallest state of matter available in high purities and large quantities. The effect of any external energy on the shape, morphology and structure can thus be studied with relative ease. The present investigation deals with the effect of a non-contact external energy on the powders of antimony and bismuth. The characteristics of powders treated by external energy are compared with the as received powders (control). The average particle sizes, 50 and 99, the sizes below which 99% of the particles are present showed significant increase and decrease indicating that the energy had caused deformation and fracture as if the powders have been subjected to high energy milling. To be able to understand the reasons for these changes the powders are characterized by techniques such as X-ray diffraction (XRD), surface area determination (BET), thermal analytical techniques such as DTA–DTG, DSC–TGA and SDTA and scanning electron microscopy (SEM). The treated powder samples exhibited remarkable changes in the powder characteristics at all structural levels starting from polycrystalline particles, through single crystal to atoms. The external energy had changed the lattice parameters of the unit cell which in turn changed the crystallite size and density. The lattice parameters are then used to compute the weight and effective nuclear charge of the atom which showed significant variation. It is speculated that the external energy is acting on the nucleus through some reversible weak interaction of larger cross section causing changes in the proton to neutron ratios. Thus the effect is felt by all the atoms, and hence the unit cell, single crystal grain and grain boundaries. The stresses generated in turn may have caused deformation or fracture of the weak interfaces such as the crystallite and grain boundaries.

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.

  19. 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)

    2001-11-30

    In 2000, the Toronto Atmospheric Fund (TAF) embarked on an initiative to quantify the potential benefits of Heat Island Reduction (HIR) strategies (shade trees, reflective roofs and pavements) in reducing cooling energy use in buildings, lowering the ambient air temperature and improve air quality. This report summarizes the efforts of Lawrence Berkeley National Laboratory (LBNL) to assess the impacts of HIR measures on building cooling- and heating-energy use. We discuss our efforts to calculate annual energy savings and peak-power avoidance of HIR strategies in the building sector of the Greater Toronto Area. The analysis is focused on three major building types that offer most saving potentials: residence, office and retail store. Using an hourly building energy simulation model, we quantify the energy saving potentials of (1) using cool roofs on individual buildings [direct effect], (2) planting deciduous shade trees near south and west walls of building [direct effect], (3) planting coniferous wind-shielding vegetation near building [direct effect], (4) ambient cooling by a large-scale program of urban reforestation with reflective building roofs and pavements [indirect effect], (5) and the combined direct and indirect effects. Results show potential annual energy savings of over $11M (with uniform residential and commercial electricity and gas prices of $0.084/kWh and $5.54/GJ) could be realized by ratepayers from the combined direct and indirect effects of HIR strategies. Of that total, about 88 percent was from the direct impact roughly divided equally among reflective roofs, shade trees and wind-shielding, and the remainder (12 percent) from the indirect impact of the cooler ambient air temperature. The residential sector accounts for over half (59 percent) of the total, offices 13 percent and retail stores 28 percent. Savings from cool roofs were about 20 percent, shade trees 30 percent, wind shielding of tree 37 percent, and indirect effect 12 percent

    In the Bay of Fundy, Atlantic sturgeon from endangered and threatened populations in the USA and Canada migrate through Minas Passage to enter and leave Minas Basin. A total of 132 sub-adult and adult Atlantic sturgeon were tagged in Minas Basin during the summers of 2010-2014 using pressure measuring, uniquely coded, acoustic transmitters with a four or eight year life span. The aim of this study was to examine spatial and seasonal distribution of sturgeon in Minas Passage during 2010-2014 and test the hypothesis that, when present, Atlantic sturgeon were evenly distributed from north to south across Minas Passage. This information is important as tidal energy extraction using in-stream, hydrokinetic turbines is planned for only the northern portion of Minas Passage. Electronic tracking data from a total of 740 sturgeon days over four years demonstrated that Atlantic sturgeon used the southern portion of Minas Passage significantly more than the northern portion. Sturgeon moved through Minas Passage at depths mostly between 15 and 45 m (n = 10,116; mean = 31.47 m; SD = 14.88). Sturgeon mean swimming depth was not significantly related to bottom depth and in deeper regions they swam pelagically. Sturgeon predominately migrated inward through Minas Passage during spring, and outward during late summer-autumn. Sturgeon were not observed in Minas Passage during winter 2012-2013 when monitoring receivers were present. This information will enable the estimation of encounters of Atlantic sturgeon with in-stream hydrokinetic turbines. PMID:27383274

    This paper reported on a study that was conducted in 2003 to 2005 at beef and diary cattle farms in Canada, where cattle manure was anaerobically digested for biogas production. The biogas was used for electrical and thermal energy cogeneration. Manure from about 7500 beef cattle at a feedlot was digested at a thermophilic temperature of 55 degrees C in two 1800 m{sup 3} above-ground digesters with a hydraulic retention time (HRT) of 14 days. The biogas had an average 58 per cent methane content and was combusted in a General Electric Jenbacher 999 kW cogeneration system. At the second farm, manure from about 165 lactating cows, 110 heifers and 40 calves was digested at a mesophilic temperature of 40 degrees C in a 500 m{sup 3} below-ground digester with a HRT of 28 days. The unique feature of this digester was that it was retrofitted in a pre-existing larger slurry storage tank. The biogas had an average 65 per cent methane content and was combusted in a 75 kW Perkins dual fuel diesel engine connected to a 65 kW Schnell generator. In 2007, when fats, oils and grease (FOG) from restaurant waste residue was added to the manure, biogas production increased by about 300 per cent and electrical energy generation increased by 180 per cent. Both systems have operated year-round from December to February at average ambient temperatures that ranged from -9 to -12 degrees Celsius. This paper addressed the long-term sustainability options for animal farm operations in terms of biogas production for electricity and thermal energy cogeneration.

  15. Ps-atom scattering at low energies

    CERN Document Server

    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...

    2012-06-15

    The driving force behind the Integrated Energy Mapping and Analysis project was the identification and analysis of a suite of pathways that the Cowichan Valley Regional District (CVRD) can utilise to increase its energy resilience, as well as reduce energy consumption and GHG emissions, with a primary focus on the residential sector. Mapping and analysis undertaken will support provincial energy and GHG reduction targets, and the suite of pathways outlined will address a CVRD internal target that calls for 75% of the region's energy within the residential sector to come from locally sourced renewables by 2050. The target has been developed as a mechanism to meet resilience and climate action target. The maps and findings produced are to be integrated as part of a regional policy framework currently under development. The third task built upon the findings of the previous two and undertook an analysis of potentially applicable distributed energy opportunities. These opportunities were analysed given a number of different parameters, which were decided upon in consultation with the CVRD. The primary output of this task was a series of cost figures for the various technologies, thus allowing comparison on a cents/kWh basis. All of the cost figures from this task have been entered into a tailor made Excel model. This 'technology cost' model is linked to the Excel scenario model utilised in task 4. As a result, as technology costs change, they can be updated accordingly and be reflected in the scenarios. Please note, that the technologies considered at present in the technology cost model are well-proven technologies, available in the market today, even though the output is being used for an analysis of development until 2050. Task 3 results are detailed in this report and both presents an initial screening for various local renewable energies, and provides the CVRD with the means of evaluating the costs and benefits of local energy productions versus

  20. Snowpack and snowmelt modeling of a subarctic catchment in northern Quebec, Canada, using an energy and mass balance approach

    2012-12-01

    There is a growing interest in modeling snowpack evolution and spring runoff in northern Quebec, Canada, where there are several large-scale hydropower complexes. This region (49th to 55th degree north), characterized by boreal forest, lakes and wetlands, is highly remote and snowpack observations are very sparse. The objective of this study is to improve the snow module of HYDROTEL, a distributed continuous hydrological model currently used to predict inflows to large hydropower reservoirs of the region, with the help of continuous in-situ measurements of snow water equivalent. Up to now HYDROTEL has relied on a mixed degree-day/energy balance method to simulate accumulation and depletion of the snow cover. This approach has the advantage of requiring a small number of input data, but under changing climate conditions such as those recently experienced unusually high temperature in late winter or rain-on-snow events it has a tendency to generate unreliable results. We thus implemented a completely physically-based snow module, CROCUS, and try to determine whether HYDROTEL could benefit from an energy and mass balance approach. CROCUS, originally developed for snowpack simulations in the French Alps, has been adapted to the specific environmental characteristics of the boreal region. The simulation can now be validated with snow water equivalent collected by a GMON sensor, which evaluates absorption of the natural ground gamma radiation by the snowpack. The number of input data required by CROCUS is more important (seven meteorological variables on an hourly basis instead of two on a daily basis for the current version of HYDROTEL's snow module) which makes it more complex to use and at this points too complex to be implemented directly as a subroutine in HYDROTEL. However, this study shows that HYDROTEL is much more effective at predicting winter and spring runoff when using CROCUS as the snow module.

  4. 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. 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)

  5. Strong field atomic ionization: Origin of high-energy structures in photoelectron spectra

    International Nuclear Information System (INIS)

    Two distinct interpretations have been proposed to account for conspicuous enhancements of the ionization peaks in the high energy part of above-threshold ionization spectra. One of them ascribes the enhancement to a multiphoton resonance involving an excited state, while other analysis performed for zero-range model potential link it to 'channel closings', i.e., to the change in the number of photons needed to ionize the atom when the laser intensity increases. We report the results of model calculations that confirm the existence of a resonant process in atoms and shed light on why short-range potential models can mimic the experimental observations

  6. Energy, cost, and emission end-use profiles of homes: An Ontario (Canada) case study

    International Nuclear Information System (INIS)

    Highlights: • Hourly electricity consumption data of seven end-uses from 25 homes are analyzed. • Hourly load, cost, and emission profiles of end-uses are developed and categorized. • Side-by-side analysis of energy, cost, and environmental effects is conducted. • Behaviour and outdoor temperature based end-uses are determined. • Share of each end-use in the total daily load, cost, and emission is determined. - Abstract: Providing information on the temporal distributions of residential electricity end-uses plays a major role in determining the potential savings in residential electricity demand, cost, and associated emissions. While the majority of the studies on disaggregated residential electricity end-use data provided hourly usage profiles of major appliances, only a few of them presented analysis on the effect of hourly electricity consumption of some specific end-uses on household costs and emissions. This study presents side-by-side analysis of energy, cost, and environment effects of hourly electricity consumption of the main electricity end-uses in a sample of homes in the Canadian province of Ontario. The data used in this study are drawn from a larger multi-stakeholder project in which electricity consumption of major end-uses at 25 homes in Milton, Ontario, was monitored in five-minute intervals for six-month to two-year periods. In addition to determining the hourly price of electricity during the monitoring period, the hourly carbon intensity is determined using fuel type hourly generation and the life cycle greenhouse gas intensities specifically determined for Ontario’s electricity fuel mix. The hourly load, cost, and emissions profiles are developed for the central air conditioner, furnace, clothes dryer, clothes washer, dishwasher, refrigerator, and stove and then grouped into eight day type categories. The side-by-side analysis of categorized load, cost, and emission profiles of the seven electricity end-uses provided information on

  9. Visualizing the large-$Z$ scaling of the kinetic energy density of atoms

    CERN Document Server

    Cancio, Antonio C

    2016-01-01

    The scaling of neutral atoms to large $Z$, combining periodicity with a gradual trend to homogeneity, is a fundamental probe of density functional theory, one that has driven recent advances in understanding both the kinetic and exchange-correlation energies. Although research focus is normally upon the scaling of energies, insights can also be gained from energy densities. We visualize the scaling of the positive-definite kinetic energy density (KED) in closed-shell atoms, in comparison to invariant quantities based upon the gradient and Laplacian of the density. We notice a striking fit of the KED within the core of any atom to a gradient expansion using both the gradient and the Laplacian, appearing as an asymptotic limit around which the KED oscillates. The gradient expansion is qualitatively different from that derived from first principles for a slowly-varying electron gas and is correlated with a nonzero Pauli contribution to the KED near the nucleus. We propose and explore orbital-free meta-GGA models...

  10. Self-energy and interaction energy of stacking fault in fcc metals calculated by embedded-atom method

    Institute of Scientific and Technical Information of China (English)

    何刚; 戎咏华; 徐祖耀

    2000-01-01

    The stacking fault energies of five fcc metals (Cu, Ag, Au, Ni and Al) with various quan-tivalences have been calculated by embedded-atom method (EAM). It indicated that the stacking fault energy is mainly determined by the metallic bond-energy and the lattice constant. Thus, monovalent fcc metals should have different stacking fault energies, contrary to Attree’s conclusion. The interaction energy between stacking faults one I 111 I layer apart in a fcc metal is found to be 1/40-1/250 of its self-energy, while it becomes zero when the two stacking faults are two layers apart. The twin energy is just half of the energy of intrinsic stacking fault energy without the consideration of lattice relaxation and the energy of a single intrinsic stacking fault is almost the same as that of extrinsic stacking fault, which are consistent with the results from the calculation of Lennard-Jones force between atoms, but differ from Attree’s result.

    We consider high energy electron scattering by hydrogen atoms in the presence of a laser field of moderate power and higher frequencies. If the field is a superposition of a linearly and a circularly polarized laser beam in a particular configuration, then we can show that circular dichroism in two photon transitions can be observed not only for the differential but also for the integrated cross sections, provided the laser-dressing of the atomic target is treated in second order perturbation theory and the coupling between hydrogenic bound and continuum states is involved.

  14. 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

    Full Text Available In this paper considering the authors previously proposed SUSY concept - ‘fermion and boson mass ratio is close to 2.26’ and considering the electroweak neutral boson, an attempt is made to understand the total energy of revolving electron in the Hydrogen atom. Thus in this paper authors succeeded in extending the basic applications of SUSY and Electroweak theory to atomic level. With further research and analysis, the hidden secrets of electroweak unification can be understood very easily.

  19. Formation of nanostructures on HOPG surface in presence of surfactant atom during low energy ion irradiation

    Science.gov (United States)

    Ranjan, M.; Joshi, P.; Mukherjee, S.

    2016-07-01

    Low energy ions beam often develop periodic patterns on surfaces under normal or off-normal incidence. Formation of such periodic patterns depends on the substrate material, the ion beam parameters, and the processing conditions. Processing conditions introduce unwanted contaminant atoms, which also play strong role in pattern formation by changing the effective sputtering yield of the material. In this work we have analysed the effect of Cu, Fe and Al impurities introduced during low energy Ar+ ion irradiation on HOPG substrate. It is observed that by changing the species of foreign atoms the surface topography changes drastically. The observed surface topography is co-related with the modified sputtering yield of HOPG. Presence of Cu and Fe amplify the effective sputtering yield of HOPG, so that the required threshold for the pattern formation is achieved with the given fluence, whereas Al does not lead to any significant change in the effective yield and hence no pattern formation occurs.

  2. 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

  3. Optical meta-atom for localization of light with quantized energy

    CERN Document Server

    Lannebère, Sylvain

    2015-01-01

    The capacity to confine light into a small region of space is of paramount importance in many areas of modern science. Here, we suggest a mechanism to store a quantized "bit" of light - with a very precise amount of energy - in an open core-shell plasmonic structure ("meta-atom") with a nonlinear optical response. Notwithstanding the trapped light state is embedded in the radiation continuum, its lifetime is not limited by the radiation loss. Interestingly, it is shown that the interplay between the nonlinear response and volume plasmons enables breaking fundamental reciprocity restrictions, and coupling very efficiently an external light source to the meta-atom. The collision of an incident optical pulse with the meta-atom may be used to release the trapped radiation "bit".

    In the exotic atoms where one atomic $1s$ electron is replaced by a $K^{-}$, the strong interaction between the $K^{-}$ and the nucleus introduces an energy shift and broadening of the low-lying kaonic atomic levels which are determined by only the electromagnetic interaction. By performing X-ray spectroscopy for Z=1,2 kaonic atoms, the SIDDHARTA experiment determined with high precision the shift and width for the $1s$ state of $K^{-}p$ and the $2p$ state of kaonic helium-3 and kaonic helium-4. These results provided unique information of the kaon-nucleus interaction in the low energy limit.

    2016-07-01

    We examined the combined effect of atomic under- and hetero-coordination on the bond relaxation and electronic binding energy of Sc, Zr, and ScZr alloying using a combination of the bond-order-length-strength (BOLS) correlation and density functional theory (DFT) calculations. Observations strongly emphasize the relevance of core-level shifts as reliable X-ray photoelectron spectroscopy experimental descriptors of core-shell catalysis reactivity, along with under-coordinated atoms in bimetallic transition metal systems. The BOLS-DFT method provides enhanced catalysis reactivity and detects surface and alloy configurations, opening up the possibility to investigate more complex systems with irregularly under- and hetero-coordinated atoms.

  6. Accreditation of testing laboratories in CNEA (National Atomic Energy Commission)

    International Nuclear Information System (INIS)

    The recognition of the technical capability of a testing laboratory is carried out by Laboratory Accreditation Bodies as the result of a satisfactory evaluation and the systematic follow up of the certified qualification. In Argentina the creation of a National Center for the Accreditation of Testing Laboratories, as a first step to assess a National Accreditation System is currently projected. CNEA, as an institution involved in technological projects and in the development and production of goods and services, has adopted since a long time ago quality assurance criteria. One of their requirements is the qualification of laboratories. Due to the lack of a national system, a Committee for the Qualification of Laboratories was created jointly by the Research and Development and Nuclear Fuel Cycle Areas with the responsibility of planning and management of the system evaluation and the certification of the quality of laboratories. The experience in the above mentioned topics is described in this paper. (author)

  7. Japan Returns to Atom. Current Status and Prospects of the Japanese Nuclear Energy

    Directory of Open Access Journals (Sweden)

    Łukasz Tolak

    2015-12-01

    Full Text Available In a year and a half after the events of March 2011, Japan excluded all their nuclear reactors, returning to fossil fuels as a basis in the energy field. The shock associated with nuclear disaster seemed to indicate an ultimate end of Japanese adventure with the atom. The situation has, however, significantly changed during the last several months, and the first nuclear reactor connected again to the electric network, is a proof of the change of the energy policy. The article aims to identify the current state of knowledge on the future of nuclear energy in the Japanese energy sector and adjustments proposed in the future energy mix. At the same time, it is an attempt to analyze the reasons that led the current Government of Prime Minister Abe to take very unpopular decisions to return to nuclear energy.

  8. Nuclear energy in the service of biomedicine: the U.S. Atomic Energy Commission's radioisotope program, 1946-1950.

    Science.gov (United States)

    Creager, Angela N H

    2006-01-01

    The widespread adoption of radioisotopes as tools in biomedical research and therapy became one of the major consequences of the "physicists' war" for postwar life science. Scientists in the Manhattan Project, as part of their efforts to advocate for civilian uses of atomic energy after the war, proposed using infrastructure from the wartime bomb project to develop a government-run radioisotope distribution program. After the Atomic Energy Bill was passed and before the Atomic Energy Commission (AEC) was formally established, the Manhattan Project began shipping isotopes from Oak Ridge. Scientists and physicians put these reactor-produced isotopes to many of the same uses that had been pioneered with cyclotron-generated radioisotopes in the 1930s and early 1940s. The majority of early AEC shipments were radioiodine and radiophosphorus, employed to evaluate thyroid function, diagnose medical disorders, and irradiate tumors. Both researchers and politicians lauded radioisotopes publicly for their potential in curing diseases, particularly cancer. However, isotopes proved less successful than anticipated in treating cancer and more successful in medical diagnostics. On the research side, reactor-generated radioisotopes equipped biologists with new tools to trace molecular transformations from metabolic pathways to ecosystems. The U.S. government's production and promotion of isotopes stimulated their consumption by scientists and physicians (both domestic and abroad), such that in the postwar period isotopes became routine elements of laboratory and clinical use. In the early postwar years, radioisotopes signified the government's commitment to harness the atom for peace, particularly through contributions to biology, medicine, and agriculture.

  11. Proceedings of the DAE-BRNS theme meeting on chemistry in atomic energy programme

    International Nuclear Information System (INIS)

    The pivotal role played by chemistry in all the stages of atomic energy programme, right from mineral exploration, materials processing, fuel fabrication, coolant, control and structural materials, reactor chemistry, fuel recycling and actinide partitioning to radioactive waste management, has been explicitly demonstrated in the last few decades. The discoveries and developments in chemical sciences that have contributed to the formulation and successful implementation of our nuclear programme are enormous. It is to the credit of all our colleagues of Department of Atomic Energy to reckon the chronology of mile stones in our programme and how they place our nation on the global map of nuclear energy. The theme meeting on Chemistry in Atomic Energy Programme is an outcome of the thinking of some of our colleagues in BARC to take stock of the accomplishments made hitherto and to prepare a roadmap to meet the challenges of future advanced reactor regimes, while safeguarding the strategic interests of mankind. It is not out-of-context to record here that India, with its rich experience, is poised to play a major role in the global nuclear power programme, through bilateral international collaborations as well as on the platform of IAEA.

  13. New approaches to the disclosure of atomic energy activities

    International Nuclear Information System (INIS)

    Nuclear activities that take place in Córdoba City are a long series of misunderstandings and confrontations with neighbors, environmental organizations, local authorities and even some sectors of the local academic community. From the analysis of conflict situations that have occurred, communication actions observed, meetings with neighbors organizations and surveys , it can be said that the low level of trust in public opinion is now a problem communicational not satisfactorily resolved. Within this framework, in 2012 there was an inflexion point when the municipality proceeded to the closure of the plant Dioxitek SA owned by CNEA and operates in Barrio Alta Córdoba of the provincial Capital. Unlike previous occasions, when negotiations between the parties allowed continuation without resolving the underlying issue, this time an agreement was reached for the final normalization of the urban space. However, the lack of compliance with the agreements reached in the past manifests itself in a high degree of mistrust of commitment. This paper presents a communication strategy aimed at increasing confidence in the fulfillment of the agreement to the satisfaction of all parties involved. By analyzing different possible communication approaches, we conclude on the appropriateness of using strategic planning as defined M. Rovere, while taking as a field of study and intervention, an scenario socially produced by the interaction of different social forces and actors, which are present mechanisms of competition, cooperation, coercion, influence and conflict. Also, for the specific application scenario, arose the need to complement the strategic with other looks, as of N. Abatedaga to plan by seeking consensus, which is thought communication actions as practices of power that enable collective subjects, achieving linkage valid rules in certain circumstances; or that of M. Chahab with regard to the need to make alternative spaces in the minds of people , broadening the

  14. Biodiversity assessment at Department of Atomic Energy (DAE) campus, Kalpakkam

    International Nuclear Information System (INIS)

    A rapid assessment of biodiversity in the DAE campus, Kalpakkam was carried out. The entire DAE campus of 3000 acres, at Kalpakkam was divided into four representative plots comprising of different landscapes namely (1) undisturbed area with dense vegetation, (2) building area, (3) water bodies with riparian cover and (4) sandy area with meager vegetation for inventorying of charismatic terrestrial/semi-aquatic fauna viz., Mammals, Birds, Reptiles, Amphibians and Butterflies. For birds, early morning surveys were made whereas for mammals evening and night surveys were followed. Midday sampling was followed for butterflies and other animals. Each plot was surveyed twice in a week over a period of one year (April 07' to March 08'). Totally 128 species of animals were identified during the survey and it has highlighted the potential of biodiversity in the campus. The diversity of butterflies is remarkable. Twenty-two butterfly species were encountered. Frogs, toads, lizards and snakes are also diverse. Five species of frogs and one species of toad were recorded. Lizards are more diverse than snakes. Nine species of lizards were encountered. Calotus versicolor is abundant followed by common skink. Totally five species of snakes were recorded. Among them Common bronzedback and Green Vine Snake were predominant. Seventy species of birds were recorded during the survey period. Black crowned night heron, Common house crow, Great cormorant, Oriental white ibis, Painted stork, Cattle egret, Common mynah are more common. Sixteen species of mammals were encountered during the survey. Wild cattle, Jackal, Jungle cat, Toddy cat, Crested porcupine and Indian civet are the major wildlife found. Indian civet and Crested porcupine are elusive animals that are diminishing from wild and their presence at this campus is an indication of less human intervention. (author)

  15. Decisions of the atomic energy authority binding on penal law?

    International Nuclear Information System (INIS)

    The essay analyses the acquittal of the accused persons by the Landgericht Hanau in the so-called Alkem process. The author criticizes the considerations of the court to disregard in case the justifying effect of valid administrative permissions because of the abuse of rights. A criminal judge cannot ignore valid acts given by authorities which he considers to be against the law. As long as he does not identify them as invalid, he has to accept the administrative act until authorities abolish their decision. (KW)

  16. 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

  17. Dynamics of Finite Energy Airy Beams Carrying Orbital Angular Momentum in Multilevel Atomic Vapors

    Wu, Zhenkun; Wang, Shun; Hu, Weifei; Gu, Yuzong

    2016-10-01

    We numerically investigate the dynamics of inward circular finite-energy Airy beams carrying different orbital angular momentum (OAM) numbers in a close-Λ three-level atomic vapor with the electromagnetically induced transparency (EIT) window. We report that due to the EIT induced by the microwave field, the transverse intensity distribution properties of Airy beam can be feasibly manipulated and modulated through adjusting OAM numbers l and the frequency detuning, as well as the propagation distance, in the multi-level atomic systems. What's more, the rotation of the beam also can be observed with different positions in atomic ensembles. The investigation may provide a useful tool for studying particle manipulation, signal processing and propagation in graded-index (GRIN) fibers.

  18. An experimental investigation of angular resolved energy distributions of atoms sputtered from evaporated aluminum films

    International Nuclear Information System (INIS)

    A study of angular resolved velocity (energy) distributions of atoms sputtered from in situ prepared metal films is described in this contribution. The velocity resolution of the set-up is based on the pulsed laser-induced fluorescence technique, i.e., scanning the narrow bandwidth dye laser radiation over the Doppler broadened absorption profile of the sputtered particles. The arrangement of the vacuum vessel and fluorescence detection optics provides the means for an independent selection of the observed emission direction and the angle of incidence. A pulsed ion gun is applied to bombard the target with noble gas ions in the energy range between 200 and 500 eV. The target assembly allows the preparation of thin metal films by evaporation on optically polished glass substrates without break of the vacuum. We report on measurements obtained with this arrangement, i.e., the determination of energy distributions of sputtered aluminum atoms. The bombardment at both the normal and the oblique incidence of the ion beam are contained in the investigation. Pronounced anisotropic effects are observed in both cases. In the case of oblique bombardment the shape of the distributions reflects cascade effects as well as single collision properties. The energy distribution is approximated with the aid of an energy spectrum involving a superposition of exponential functions. The experimental results are compared with simulations obtained by the Monte Carlo code TRIM.SP

    2016-01-01

    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.

  5. 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

  7. Effects of laser radiation field on energies of hydrogen atom in plasmas

    International Nuclear Information System (INIS)

    In this study, for the first time, the Schrödinger equation with more general exponential cosine screened Coulomb (MGECSC) potential is solved numerically in the presence of laser radiation field within the Ehlotzky approximation using the asymptotic iteration method. The MGECSC potential includes four different potential forms in consideration of different sets of the parameters in the potential. By applying laser field, the total interaction potential of hydrogen atom embedded in plasmas converts to double well-type potential. The plasma screening effects under the influence of laser field as well as confinement effects of laser field on hydrogen atom in Debye and quantum plasmas are investigated by solving the Schrödinger equation with the laser-dressed MGECSC potential. It is resulted that since applying a monochromatic laser field on hydrogen atom embedded in a Debye and quantum plasma causes to shift in the profile of the total interaction potential, the confinement effects of laser field on hydrogen atom in plasmas modeled by the MGECSC potential change localizations of energy states

    2010-06-01

    Forces of adhesion have been measured for interactions involving self-assembled monolayers or polymer-film structures that had each been deposited onto a gold-coated glass substrate and a probing, gold-coated cantilever. The data have been fitted into mathematical models that allow the calculation of surface energy by considering the work done for the separation of the identically coated contacting surfaces. These values of surface energy are in close agreement with those from corresponding contact angle determinations, highlighting the potential usefulness of the technique for the study of surfaces at a resolution level approaching 1000 atoms. Comparative studies show that the employment of the atomic force microscopy technique may be preferable for the study of samples that are susceptible to penetration by liquids or for investigations under conditions that exceed the useful limits of conventional probing techniques involving liquids.

    Foster, T.; Picard-Aitken, M.; Hillman-Beauchesne, O.; Campbell, D.; Archambault, E.

    2010-03-31

    In February 2009, the U.S. and Canada established the Clean Energy Dialogue, aiming at identifying ways to reduce greenhouse gases, in order to fight against global warming. 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.

Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programs Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of

    Z-Pinch Inertial Fusion Energy (Z-IFE) complements and extends the single-shot z-pinch fusion program on Z to a repetitive, high-yield, power plant scenario that can be used for the production of electricity, transmutation of nuclear waste, and hydrogen production, all with no CO{sub 2} production and no long-lived radioactive nuclear waste. The Z-IFE concept uses a Linear Transformer Driver (LTD) accelerator, and a Recyclable Transmission Line (RTL) to connect the LTD driver to a high-yield fusion target inside a thick-liquid-wall power plant chamber. Results of RTL and LTD research are reported here, that include: (1) The key physics issues for RTLs involve the power flow at the high linear current densities that occur near the target (up to 5 MA/cm). These issues include surface heating, melting, ablation, plasma formation, electron flow, magnetic insulation, conductivity changes, magnetic field diffusion changes, possible ion flow, and RTL mass motion. These issues are studied theoretically, computationally (with the ALEGRA and LSP codes), and will work at 5 MA/cm or higher, with anode-cathode gaps as small as 2 mm. (2) An RTL misalignment sensitivity study has been performed using a 3D circuit model. Results show very small load current variations for significant RTL misalignments. (3) The key structural issues for RTLs involve optimizing the RTL strength (varying shape, ribs, etc.) while minimizing the RTL mass. Optimization studies show RTL mass reductions by factors of three or more. (4) Fabrication and pressure testing of Z-PoP (Proof-of-Principle) size RTLs are successfully reported here. (5) Modeling of the effect of initial RTL imperfections on the buckling pressure has been performed. Results show that the curved RTL offers a much greater buckling pressure as well as less sensitivity to imperfections than three other RTL designs. (6) Repetitive operation of a 0.5 MA, 100 kV, 100 ns, LTD cavity with gas purging between shots and automated operation is

  18. An overview of Scicon activities on the SYVAC development from January 1983 - March 1984

    International Nuclear Information System (INIS)

    The Department of the Environment has embarked on a programme to develop computer models to help with assessment of sites suitable for the disposal of nuclear wastes. The first priority is to produce a system based on the System Variability Analysis Code (SYVAC) obtained from Atomic Energy of Canada Ltd., suitable for assessing radioactive waste disposal in land repositories containing non heat producing wastes from typical UK sources. The requirements of the SYVAC system development were so diverse that each portion of the development was contracted to a different company. This document describes Scicon's role in promoting the integrity, integration, verification and usability of the SYVAC A computer system. (U.K.)

  20. Final results of the fifth three-dimensional dynamic Atomic Energy Research benchmark problem calculations

    International Nuclear Information System (INIS)

    The paper gives a brief survey of the fifth three-dimensional dynamic Atomic Energy Research benchmark calculation results received with the code DYN3D/ATHLET at NRI Rez. This benchmark was defined at the seventh Atomic Energy Research Symposium (Hoernitz near Zittau, 1997). Its initiating event is a symmetrical break of the main steam header at the end of the first fuel cycle and hot shutdown conditions with one stuck out control rod group. The calculations were performed with the externally coupled codes ATHLET Mod.1.1 Cycle C and DYN3DH1.1/M3. The standard WWER-440/213 input deck of ATHLET code was adopted for benchmark purposes and for coupling with the code DYN3D. The first part of paper contains a brief characteristics of NPP input deck and reactor core model. The second part shows the time dependencies of important global and local parameters. In comparison with the results published at the eighth Atomic Energy Research Symposium (Bystrice nad Pernstejnem, 1998), the results published in this paper are based on improved ATHLET descriptions of control and safety systems.

  3. 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)

  6. The interplay between neuronal activity and actin dynamics mimic the setting of an LTD synaptic tag

    OpenAIRE

    Szabó, Eszter C.; Manguinhas, Rita; Fonseca, Rosalina

    2016-01-01

    Persistent forms of plasticity, such as long-term depression (LTD), are dependent on the interplay between activity-dependent synaptic tags and the capture of plasticity-related proteins. We propose that the synaptic tag represents a structural alteration that turns synapses permissive to change. We found that modulation of actin dynamics has different roles in the induction and maintenance of LTD. Inhibition of either actin depolymerisation or polymerization blocks LTD induction whereas only...

  10. Overview of Canada's uranium industry

    International Nuclear Information System (INIS)

    This paper places Canada's uranium industry in its international context. Most uranium, except that produced in the United States, is traded internationally. A brief history of the industry worldwide is given to show how the principal producing areas have fared to date. The industry is young, highly cyclical, and still far from achieving stability. Uranium is a single end-use commodity, entirely dependent on the generation of electricity in nuclear stations, and is without price elasticity: lowering the price does not increase demand. The typical nuclear fuel processing chain has not encouraged or led to much vertical integration. Uranium is subject to more governmental control than any other commodity. The principal market is located in the industrial countries of western Europe, the United States, Canada, and the far east. The uranium supply-demand situation is reviewed, including the current and near-term oversupply and the longer term outlook to 1995. The major negative impact of reactor cancellations and deferments in the United States is discussed. Because of the difficulty in getting reactors on line, it has become easier to forecast the demand for uranium over the next 10 years. It is more difficult to predict how that demand will be met from the more than ample competing sources. Canada's potential for supplying a significant portion of this demand is considered in relation to producers and potential new producers in other countries

  13. Bats and wind energy in Canada : causes, consequences and variation of fatalities

    Energy Technology Data Exchange (ETDEWEB)

    Barclay, R.; Baerwald, E. [Calgary Univ., AB (Canada). Dept. of Biology

    2008-07-01

    This presentation discussed various aspects of bat mortalities that occur at wind turbines. The majority of bat fatalities related to wind turbines take place in the Fall among Hoary, Silver-haired, and Eastern red bat species. The fatality rate varies geographically. Migratory routes explain the geographic variations of bats. Tall wind turbines kill more bats than birds. Activity and fatality rates vary geographically. Small-scale geographic patterns were discussed along with bat mortality rates at different wind farm facilities. Higher turbines are known to disrupt bat activities. During a 1-year period in Alberta only 189 bird mortalities were recorded compared to 1775 bat mortalities. Across North America, 3940 bats died in collisions with wind turbines compared to only 1241 birds. It was concluded that monitoring studies conducted from the ground do not fully indicate the risks of wind turbines to bats. tabs., figs.

  14. Synoptic controls on the surface energy and water budgets in sub-arctic regions of Canada

    Science.gov (United States)

    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.

  16. 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.

  20. On the combination of a low energy hydrogen atom beam with a cold multipole ion trap

    International Nuclear Information System (INIS)

    The first part of the activities of this thesis was to develop a sophisticated ion storage apparatus dedicated to study chemical processes with atomic hydrogen. The integration of a differentially pumped radical beam source into an existing temperature variable 22- pole trapping machine has required major modifications. Since astrophysical questions have been in the center of our interest, the introduction first gives a short overview of astrophysics and -chemistry. The basics of ion trapping in temperature variable rf traps is well-documented in the literature; therefore, the description of the basic instrument (Chapter 2) is kept rather short. Much effort has been put into the development of an intense and stable source for hydrogen atoms the kinetic energy of which can be changed. Chapter 3 describes this module in detail with emphasis on the integration of magnetic hexapoles for guiding the atoms and special treatments of the surfaces for reducing H-H recombination. Due to the unique sensitivity of the rf ion trapping technique, this instrument allows one to study a variety of reactions of astrochemical and fundamental interest. The results of this work are summarized in Chapter 4. Reactions of CO2+ with hydrogen atoms and molecules have been established as calibration standard for in situ determination of H and H2 densities over the full temperature range of the apparatus (10 K-300 K). For the first time, reactions of H- and D-atoms with the ionic hydrocarbons CH+, CH2+, and CH4+ have been studied at temperatures of interstellar space. A very interesting, not yet fully understood collision system is the interaction of protonated methane with H. The outlook presents some ideas, how to improve the new instrument and a few reaction systems are mentioned which may be studied next. (orig.)

  6. Residual risks of the 13th amendment to the German Atomic Energy Act

    International Nuclear Information System (INIS)

    The 13th amendment to the German Atomic Energy Act, which was adopted by the German federal parliament on June 30 and entered into force on August 6, 2011, must be judged in the light of its genesis. Federal Chancellor Merkel, in her government declaration of June 9, 2011, had mentioned topics such as residual risk, safety standards, and risk assumptions, on which the federal government, in the week after the event of March 11, 2011, had commissioned the Advisory Committee on Reactor Safeguards (RSK) to conduct a comprehensive safety review of all German nuclear power plants, and appointed an Ethics Committee to write an opinion on safe energy supply. On the basis of quickly drafted reports, the federal cabinet, without any international harmonization (EU, IEA), adopted a draft opt out law on June 6, 2011. How should the declarations by the Federal Chancellor on June 9, 2011 be classified in terms of atomic energy law? In her words, it all revolved around the residual risk. The debate, which has been shifted to the realm of constitutional law, is open to considerations and steps to attack the new opt out law on grounds of material unconstitutionality (violation of the property guarantee under Sec. 14 or the principle of equality under Art.3 of the Basic Law). As far as final storage is concerned, the amendment to the German Atomic Energy Act announced still for this year, also for transposition of the EURATOM Directive of July 19, 2011 about nuclear waste management, the ''re-assessment of the residual risk'' is not likely to play a role. All these events are reminiscent of a sentence by former Federal Chancellor Schmidt: ''The history of the NATO dual-track decision remains a textbook case showing that even in a democracy emotions using ethical arguments, mixed with demagogy, can become strong enough to cast aside balanced reason.'' There is also a distinction by Max Weber between ''ethics of ideology'' and ''ethics of responsibility''. (orig.)

    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.

  9. Nuclear energy in the service of biomedicine: the U.S. Atomic Energy Commission's radioisotope program, 1946-1950.

    2006-01-01

    The widespread adoption of radioisotopes as tools in biomedical research and therapy became one of the major consequences of the "physicists' war" for postwar life science. Scientists in the Manhattan Project, as part of their efforts to advocate for civilian uses of atomic energy after the war, proposed using infrastructure from the wartime bomb project to develop a government-run radioisotope distribution program. After the Atomic Energy Bill was passed and before the Atomic Energy Commission (AEC) was formally established, the Manhattan Project began shipping isotopes from Oak Ridge. Scientists and physicians put these reactor-produced isotopes to many of the same uses that had been pioneered with cyclotron-generated radioisotopes in the 1930s and early 1940s. The majority of early AEC shipments were radioiodine and radiophosphorus, employed to evaluate thyroid function, diagnose medical disorders, and irradiate tumors. Both researchers and politicians lauded radioisotopes publicly for their potential in curing diseases, particularly cancer. However, isotopes proved less successful than anticipated in treating cancer and more successful in medical diagnostics. On the research side, reactor-generated radioisotopes equipped biologists with new tools to trace molecular transformations from metabolic pathways to ecosystems. The U.S. government's production and promotion of isotopes stimulated their consumption by scientists and physicians (both domestic and abroad), such that in the postwar period isotopes became routine elements of laboratory and clinical use. In the early postwar years, radioisotopes signified the government's commitment to harness the atom for peace, particularly through contributions to biology, medicine, and agriculture. PMID:17575955

  10. 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.

    The Canadian Climate Program (CCP) was created in 1979 as a national effort to understand global climate variability and changes as they affect Canada and the adjacent oceans. The CCP was also intended as a contribution to the World Climate Programme. A review of Canada` progress to date in improving its commitments to science and adaptation regarding climatic change was provided, including improvements in evaluation and coordination of systematic observations, in the creation of improved statistical and analytical tools, and tools to assess Canadian options and opportunities aimed at reducing risks of climate change. Boreal forests, permafrost-saturated Arctic tundra, and snow-and ice-covered areas were identified as areas of special Canadian concern. Climate change impacts and adaptations in Canada were also reviewed.

    Atomic-scale quantification of chemical composition across oxide interfaces is important for understanding physical properties of epitaxial oxide nanostructures. Energy-dispersive X-ray spectroscopy (EDS) in an aberration-corrected scanning transmission electron microscope was used to quantify chemical composition across the interface of ferromagnetic La{sub 0.7}Sr{sub 0.3}MnO{sub 3} and antiferromagnetic BiFeO{sub 3} quantum structure. This research demonstrates that chemical composition at atomic columns can be quantified by Gaussian peak-fitting of EDS compositional profiles across the interface. Cation diffusion was observed at both A- and B-sublattice sites; and asymmetric chemical profiles exist across the interface, consistent with the previous studies.

    2010-07-01

    This research investigated the role of learning approach on the ground state energy calculation of Helium atom in improving the concepts of science teachers at university level. As the exact solution of several particles is not possible here we used approximation methods. Using this method one can understand easily the calculation of ground state energy of any given function. Variation Method is one of the most useful approximation methods in estimating the energy eigen values of the ground state and the first few excited states of a system, which we only have a qualitative idea about the wave function. The objective of this approach is to introduce and involve university teacher in new research, to improve their class room practices and to enable teachers to foster critical thinking in students.

    Sandia National Laboratories is collaborating with the National Research Council (NRC) Canada and the National Renewable Energy Laboratory (NREL) to develop a decision-support model that will evaluate the tradeoffs associated with high-latitude algae biofuel production co-located with wastewater, CO2, and waste heat. This project helps Canada meet its goal of diversifying fuel sources with algae-based biofuels. The biofuel production will provide a wide range of benefits including wastewater treatment, CO2 reuse and reduction of demand for fossil-based fuels. The higher energy density in algae-based fuels gives them an advantage over crop-based biofuels as the “production” footprint required is much less, resulting in less water consumed and little, if any conversion of agricultural land from food to fuel production. Besides being a potential source for liquid fuel, algae have the potential to be used to generate electricity through the burning of dried biomass, or anaerobically digested to generate methane for electricity production. Co-locating algae production with waste streams may be crucial for making algae an economically valuable fuel source, and will certainly improve its overall ecological sustainability. The modeling process will address these questions, and others that are important to the use of water for energy production: What are the locations where all resources are co-located, and what volumes of algal biomass and oil can be produced there? In locations where co-location does not occur, what resources should be transported, and how far, while maintaining economic viability? This work is being funded through the U.S. Department of Energy (DOE) Biomass Program Office of Energy Efficiency and Renewable Energy, and is part of a larger collaborative effort that includes sampling, strain isolation, strain characterization and cultivation being performed by the NREL and Canada’s NRC.

  1. Radiative Energy Shifts of an Atom Coupled to the Derivative of a Scalar Field near a Reflecting Boundary

    Institute of Scientific and Technical Information of China (English)

    LI Cheng-Gai; YU Hong-Wei

    2009-01-01

    We study the radiative energy level shifts of a two-level atom in dipole coupling to the derivative of a massless scalar quantum field in a spacetime with a perfectly reflecting boundary, and calculate the contributions of vacuum fluctuations and radiation reaction to the level shift. It is found that the energy level shift of the excited state is an oscillating function of the atom's distance from the boundary and it can either be positive or negative,while that of the ground state is always positive. The most remarkable feature is that the energy level shift of the ground state behaves like 1/z4 when the atom's distance from the boundary, z, is very large as compared to the transition wavelength of the atom, while it behaves like 1/z3 when z is very small.

  4. Some considerations on disposal and management of solid radioactive wastes in the Institute of Atomic Energy

    International Nuclear Information System (INIS)

    The Institute of Atomic Energy was established in 1958; it is a comprehensive institute in the field of nuclear science and technology, and it is also the oldest research centre on nuclear energy in China. At present the main facilities in the institute are: a heavy-water research reactor (HWRR) with thermal power of 15 MW (before reconstruction, the maximum thermal power of the HWRR was 10 MW), a 3 MW swimming pool light-water reactor for material testing, a few zero-power facilities, five accelerators, a nuclear fuel reprocessing technology laboratory, and three radioisotope production workshops, and so on. For the low- and intermediate-level solid radioactive waste produced at the institute, the main management measure is to store the waste in a special reinforced concrete building. The first of that kind of building was put into use in 1961. The annual average amount of low-level waste stored was 40 m3, only a very small share of that was intermediate-level waste. By the end of 1982, the entire capacity viz. 900 m3 of the storage building was used. In 1983, a new storage building with an effective volume of 900 m3 was constructed and put into use. In the operation of the new storage, the experience gained was utilized. As a larger comprehensive research institute in the field of nuclear science and technology and taking part in the nuclear energy development programme in China, the Institute of Atomic Energy is carryng out several research projects of the nuclear power safety of China. There is also a vital interest in the topic of site investigation techniques and assessment methods for underground disposal of radioactive wastes, although these studies in China are in the beginning stages

    Bioenergy refers to all forms of renewable energy that are derived from plant materials produced by photosynthesis. Biomass fuels can be derived from wood, agricultural crops and other organic residues. These fuels can be obtained from many sources in Canada, including sawmills, woodworking shops, forest operations and farms. This study deals with the socio-economic aspects of bioenergy development. Normally, the socio-economic impact of bioenergy can be measured in terms of economic indices, such as employment, monetary gains, etc. Recently some pulp and paper mills in northwestern Ontario have initiated bioenergy plants to generate heat and electricity for their use. The Ontario Ministry of Energy and Infrastructure is investigating the possibility of replacing coal with renewable forest biomass as feedstock for the Atikokan Power Generating Station (APGS) located in northwestern Ontario. The APGS has already successfully tested 100 % wood biomass feedstock instead of coal. This study evaluates the socio-economic impacts of wood biomass utilization for energy production in small communities in northwestern Ontario Canada. (orig.)

    Specialization is a pervasive movement in medicine. How specialties develop is a complex phenomenon and does not depend solely on the growth of knowledge. The history of geriatrics in Canada is presented as an example of specialization in our country. The gestation period extended over decades. Practitioners moved from partial specialization to a full-time practice in the care of older patients. Opposition to the emerging specialty was mounted by established fields of practice. The choices made by the leaders of Canadian geriatrics molded the evolution of the specialty and have contributed to its precarious status at the present time.

    Atomic-resolution quantification of the elemental ratio of Fe to Mn at the octahedral and tetrahedral sites in brownmillerite Ca2Fe1.07Mn0.93O5 was determined using electron energy-loss spectroscopy combined with aberration-corrected scanning transmission electron microscopy. The combined techniques revealed that oversampling of the spectral imaging data yielded a spatially resolved area that very nearly reflects atomic resolution (∼1.2 Å radius). The average experimental ratios of Fe to Mn within this region were 17.5:82.5 for the octahedral sites and 81.6:18.4 for the tetrahedral sites. The elemental ratio in an octahedral atomic column was successfully extracted by estimating the mixing of signals from nearest neighbor columns. The results indicated that the ratio of Fe to Mn was 13:87 at the octahedral site, which is in good agreement with the results of neutron diffraction analysis. In addition, the uncertainty of experimental results obtained by using an average 1.2 Å radius was less than 10% at octahedral sites, depending on the sample thickness. In contrast, the experimental error due to dechanneling of incident electrons was larger at the tetrahedral sites. This experimental procedure has wide application for determining the spatially resolved composition ratio of elements in perovskite-like compounds. PMID:27341006

We estimated the magnitude of BBR-shift of this results in the hydrogen-like atom. The order of magnitude indicated the two loop correction of the real photon is feeble, but that thermal relativistic one-loop self-energy correction and the thermal two-loop self-energy corrections induced by real and virtual photon are abnormal high, which may exceed the leading order correction of BBR in the hydrogen with high $Z$ or low $T$.

  20. Electron capture by impact of highly partially stripped ions on hydrogen atom in low collision energies

    International Nuclear Information System (INIS)

    Based on the reaction windows of electron capture obtained by using the two-state Landau-Zener model, the electron capture processes in collision of bare ions and highly partially stripped ions with hydrogen atoms are analysed. The capture cross sections predicted by multichannel Landau-Zener method are reliable if the cross points between the initial and final diabatic potential energy curves are located in the corresponding reaction windows. The calculations by the multichannel Landau-Zener method show that the present theoretical results are in accord with the analyses for slow C3+ + H and 5+ + H collisions

    A method to provide an article of manufacture of iron oxide on indium tin oxide for solar energy conversion. An atomic layer epitaxy method is used to deposit an uncommon bixbytite-phase iron (III) oxide (.beta.-Fe.sub.2O.sub.3) which is deposited at low temperatures to provide 99% phase pure .beta.-Fe.sub.2O.sub.3 thin films on indium tin oxide. Subsequent annealing produces pure .alpha.-Fe.sub.2O.sub.3 with well-defined epitaxy via a topotactic transition. These highly crystalline films in the ultra thin film limit enable high efficiency photoelectrochemical chemical water splitting.

    With the concept of super-atom,first principles calculations propose a new type of super stable cage clusters AlnH3n that are much more energetic stable than the well established clusters,AlnHn+2.In the new clusters,the aluminum core-frame acts as a super-atom with n vertexes and 2n Al-Al edges,which allow to adsorb n hydrogen atoms at the top-site and 2n at the bridge-site.Using Al12H36 as the basic unit,stable chain structures,(Al12H36)m,have been constructed following the same connection mechanism as for (AlH3)n linear polymeric structures.Apart from high hydrogen percentage per molecule,calculations have shown that these new clusters possess large heat of formation values and their combustion heat is about 4.8 times of the methane,making them a promising high energy density material.

  7. The Cold War legacy of regulatory risk analysis: The Atomic Energy Commission and radiation safety

    Science.gov (United States)

    Boland, Joseph B.

    From its inception in 1946 the Atomic Energy Commission pioneered the use of risk analysis as a mode of regulatory rationality and political rhetoric, yet historical treatments of risk analysis nearly always overlook the important role it played in the administration of atomic energy during the early Cold War. How this absence from history has been achieved and why it characterizes most historical accounts are the subjects of Chapter II. From there, this study goes on to develop the thesis that the advent of the atomic bomb was a world-shattering event that forced the Truman administration to choose between two novel alternatives: (1) movement towards global governance based initially on cooperative control of atomic energy or (2) unsparing pursuit of nuclear superiority. I refer to these as nuclear internationalism and nuclear nationalism, respectively. Each defined a social risk hierarchy. With the triumph of nuclear nationalism, nuclear annihilation was designated the greatest risk and a strong nuclear defense the primary means of prevention. The AEC's mission in the 1950s consisted of the rapid development of a nuclear arsenal, continual improvements in weapons technologies, and the promotion of nuclear power. The agency developed a risk-based regulatory framework through its dominant position within the National Committee on Radiation Protection. It embraced a technocratic model of risk analysis whose articulation and application it controlled, largely in secret. It used this to undergird a public rhetoric of reassurance and risk minimization. In practice, safety officials adjusted exposure levels within often wide parameters and with considerable fluidity in order to prevent safety concerns from interfering with operations. Secrecy, the political climate of the time, and a lack of accountability enabled the agency to meld technical assessments with social value judgments in a manner reflective of nuclear nationalism's risk hierarchy.

  8. Views concerning the admissibility of actions to set aside, brought under the Atomic Energy Law

    International Nuclear Information System (INIS)

    In some respects, the Federal Constitutional Court's decisions of July 17, 1980 (on Wyhl reactor) and of December 22, 1980 (on Stade reactor) will set up standards for the admissibility of future actions brought by third parties to set aside licences granted unter the Atomic Energy Law, at least, they will show the way. Above all, important statements on fundamental problems posed by the right to file suit are to be found in these decisions, especially on the substantiation of complaints, as well as significant observations on the constitutionality, the individual interpretation and the application of regulations laid down in the Atomic Energy Law on the preclusion of objections. This clarification and positioning of points has been of immense interest to science and practice. They support the understanding of the judicial system of legal protection even within the constitutional framework, and these decisions, made on the basis of a correctly understood and highly esteemed guarantee of legal protection (para. 4 of art. 19 of the Basic Law) will have effects that may call a halt to the exploitation of this guarantee. This would not only be good for our constitutional state but also for the further development of economy and technology that is required in our country. (orig./HP)

    We have investigated the atomic structure of the "multilayer silicene" grown on the Ag(111) single crystal surface by using low energy electron diffraction (LEED) and scanning tunneling microscopy (STM). We measured the intensity of the LEED spot as a function of the incident electron energy (I-V curve) and analyzed the I-V curve using a dynamical LEED theory. We have found that the Si(111)(√{ 3} ×√{ 3})-Ag model well reproduces the I-V curve whereas the models consisting of the honeycomb structure of Si do not. The bias dependence of the STM image of multilayer silicene agrees with that of the Si(111)(√{ 3} ×√{ 3})-Ag reconstructed surface. Consequently, we have concluded that the multilayer silicene grown on Ag(111) is identical to the Si(111)(√{ 3} ×√{ 3})-Ag reconstructed structure.

  14. Using atom interferometry to detect dark energy

    Science.gov (United States)

    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.

    2011-02-02

    The resonant charge exchange between atoms and surfaces is described by considering a localized atomistic view of the solid within the Anderson model. The presence of a surface energy gap is treated within a simplified tight-binding model of the solid, and a proper calculation of the Hamiltonian terms based on a LCAO expansion of the solid eigenstates is performed. It is found that interference terms jointly with a surface projected gap maximum at the {Gamma} point and the Fermi level inside it, lead to hybridization widths negligible around the Fermi level. This result can explain experimental observations related to long-lived adsorbate states and anomalous neutral fractions of low energy ions in alkali/Cu(111) systems.

  16. Charge transfer in the interactions of partially stripped ions with atoms at intermediate and high energies

    International Nuclear Information System (INIS)

    The Coulomb-Born (CB) approximation has been employed to study charge transfer cross sections in collisions of Cq+, Nq+ and Oq+ (q = 1-5) with atomic hydrogen in ground state in the energy range of 30-200 keV/amu. The interaction of the active electron with the incoming projectile ion has been approximated by a model potential containing both a long-range part and a short-range part. Variations of total capture cross sections with impact energy compare favourable well with the available experimental observations and with other theoretical findings. In addition, sub-shell distributions of total capture cross sections are given in graphical form. However, we are unable to find any oscillation in the charge-state dependence of total capture cross sections. (author)

    1995-12-01

    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.

    In order to improve the accuracy of laser atom probe analyses, it is important to understand all the physical processes induced by the combination of the high electrical field and the femtosecond laser beam during field evaporation. New information can be accessed from the energy of evaporated surface atoms or field-ionised atoms of an imaging gas. In order to study the ions energy, we combine La-APT and FIM analyses in a new experimental setup equipped with electrostatic lenses. We report measurements for semiconductors and oxides and we study the influence of the illumination conditions (laser power and wavelength), the evaporation rate, the sample geometry and the tip preparation processes. The results are discussed taking into account the resistive properties of non-metallic samples and the photo-stimulated conductivity. This work clarifies the role of the laser and DC field in the energy deficit of field evaporated ions. PMID:25484362

Data are given on the amounts of radioactivity discharged as waste from establishments of the United Kingdom Atomic Energy Authority, the nuclear power stations operated by the Electricity Generating Boards and other users of radioactive materials. Studies of the behaviour of radioactivity in the environment are reported with particular reference to food chains and other potential sources of irradiation of the public. The results of environmental monitoring are presented and estimates are made of radiation doses received by individual members of the public and larger population groups as a result of waste disposal. It is concluded that the doses received are all within the appropriate limits recommended by the International Commission on Radiological Protection, and in most cases are trivial. (author)

    National Atomic Energy Agency (NAEA) or Badan Tenaga Atom Nasional (BATAN) is a non departmental governmental agency, headed by a Director General who is directly responsible to the President. Center for Standardization and Radiation Safety Research (CSRSR) is one of the research centers within the deputy for the assessment of nuclear science and technology of the NAEA. The main task of the CSRSR is to implement research and development program, development and services in the field of radiation safety, standardization, dosimetry, radiation health as well as the application of nuclear techniques in medicine, according to the policy confirmed by the director general of BATAN. Task of radiation protection division is to set up programs and to develop radiation protection, personal monitoring system and radiation level of the working areas and their surroundings as well as dose limitation system, to carry out technical up grading of radiation protection officials skill and to help coping with radiation accident. The key factor on contamination monitoring is to reduce human error and mechanical failures. These problems can be achieved to the highest degree by developing knowledge and skill of staffs via trainings or courses on contamination and decontamination, so that they are hoped to become trained and qualified staffs.

  3. Determination of the effective atomic and mass numbers for mixture and compound materials in high energy photon interactions

    International Nuclear Information System (INIS)

    In consideration the radiological properties of materials and studying the scattering processes in atomic and nuclear physics, the effective atomic and mass numbers is widely employed. These numbers have been calculated for any mixed or composite materials in interaction with high energy photons (Linac in radiation therapy). A pair equation in terms of these numbers is obtained. The first equation has been derived from the conservation of mass energy law and the second by minimizing the binding energy from the semiempirical mass formula (Myers and Swiatecki formula) that gives a relation between atomic and mass numbers for stable nuclei approximately. By these equations one can obtain the effective atomic and mass numbers for any compound or mixed materials uniquely. These numbers are calculated for some materials and compared with the other studies. (author)

    A direct method is proposed for reconstruction of the effective atomic number by means of multi-energy radiography of the material. The accuracy of the method is up to 95% . Advantages over conventional radiographic methods, which ensure accuracy of just about 50%, are discussed. A physical model has been constructed, and general expressions have been obtained for description of the effective atomic number in a two-energy monitoring scheme. A universal dependence has been predicted for the effective atomic number as a function of relative (two-energy) radiographic reflex. The established theoretical law is confirmed by the experimental data presented. The proposed development can find multiple applications in non-destructive testing and related fields, including those in the civil sphere as well as anti-terrorist activities.

    Electron capture processes are important in the study of comets, controlled fusion energy, anti-matter atoms, and proposed one-electron ions in Rydberg states. There are few studies for low energy. At NIST, highly-charged ions extracted from an electron-beam ion trap can be isolated with stripped neon ions are held in the trap for varying lengths of time and allowed to interact with different background gases at multiple pressures. The ions are then pulsed to a time-of-flight detector, to count the population of each charge state. Analysis yields information about the trap loss and single-electron capture rates. Moreover, evidence of double-electron capture is observed at low background gas pressures. Related work involves the resonant charge exchange of fully-stripped neon ions with laser-excited rubidium atoms to produce highly-excited one-electron ions, enabling a new measurement of the Rydberg constant.

    The collision-free, room temperature gas-phase photodissociation dynamics of CH3CFCl2 (HCFC-141b) was studied using Lyman- laser radiation (121.6 nm) by the laser photolysis/laserinduced fluorescence `pump/probe’ technique. Lyman- radiation was used both to photodissociate the parent molecule and to detect the nascent H atom products via (22P → 12S) laser-induced fluorescence. Absolute H atom quantum yield, H = (0.39 ± 0.09) was determined by calibration method in which CH4 photolysis at 121.6 nm was used as a reference source of well-defined H atom concentrations. The line shapes of the measured H atom Doppler profiles indicate a Gaussian velocity distribution suggesting the presence of indirect H atom formation pathways in the Lyman- photodissociation of CH3CFCl2. The average kinetic energy of H atoms calculated from Doppler profiles was found to be T(lab) = (50 ± 3) kJ/mol. The nearly statistical translational energy together with the observed Maxwell-Boltzmann velocity distribution indicates that for CH3CFCl2 the H atom forming dissociation process comes closer to the statistical limit.

    While collisions of electrons with hydrogen atoms pose a well studied and in some sense closed problem, there is still no free computer code ready for “production use”, that would enable applied researchers to generate necessary data for arbitrary impact energies and scattering transitions directly if absent in on-line scattering databases. This is the second article on the Hex program package, which describes a new computer code that is, with a little setup, capable of solving the scattering equations for energies ranging from a fraction of the ionization threshold to approximately 100 eV or more, depending on the available computational resources. The program implements the exterior complex scaling method in the B-spline basis.

    The present re-edition closes a gap that had existed in particular in the German literature on European atomic energy law. This field of law is becoming more and more important through the introduction of new directives and regulations. The textbook starts with a discussion of the principles and international regulations of European atomic energy law. Forming its core is a presentation of the Euratom Treaty with all its regulations, directives, and decisions taken by the European Commission and the European Court of Justice. Since the Fukushima disaster, and as a result of the still ongoing renaissance of nuclear energy in many countries outside of Europe, a substantial demand has grown for information on international and specifically European nuclear energy law.

    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.

    Foundation and prospects of the new original technique of the sputtering yield determination of electro-conducting materials and sub-atomic layers on their surface by light gas ions the pre-threshold energy region (from 10 to 500 eV) are considered. The technique allows to identify individual surface vacancies, i.e., to count individual sputtered atoms directly. A short review of the original results obtained by using the developed techniques is given. Data are presented and analyzed concerning energy thresholds of the sputtering onset and energy dependences of sputtering yield in the threshold energy region for beryllium, tungsten, tungsten oxide, alternating tungsten-carbon layers, three carbon materials as well as for sub-atomic carbon layers on surface of certain metals at their bombardment by hydrogen, deuterium and/or helium ions

    The effects of substitution of legumes for grains in cropping systems were studied. Legumes require less energy to produce than most other crops and can reduce the energy costs of non-legume crops which follow the legume in the rotation. Legumes have low nitrogen fertilizer requirements, they leave some biologically fixed nitrogen in the soil after harvest, and yields of following crops may be increased by rotation effects. A well designed ethanol production system can produce two units of renewable energy for every unit of fossil fuel-based energy required to produce the grain crop and process it to ethanol. Forty per cent of the energy costs of ethanol is the energy cost of production. Therefore, methods that reduce the energy cost of producing the feedstock would reduce the energy cost of ethanol. 8 refs., 4 tabs.

    The present review includes the description of theoretical methods for the investigations of the spectra of hydrogen-like systems. Various versions of the quasipotential approach and the method of the effective Dirac equation are considered. The new methods, which have been developed in the eighties, are described. These are the method for the investigation of the spectra by means of the quasipotential equation with the relativistic reduced mass and the method for a selection of the logarithmic corrections by means of the renormalization group equation. The special attention is given to the construction of a perturbation theory and the selection of graphs, whereof the contributions of different orders of $\\alpha$, the fine structure constant, to the energy of the fine and hyperfine splitting in a positronium, a muonium and a hydrogen atom could be calculated. In the second part of this article the comparison of the experimental results and the theoretical results concerning the wide range of topics is produce...

    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.

  19. 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.

    In recent work, a new cosmological paradigm implied a mass-radius relation, suggesting a universal tension related to the background dark energy (cosmological constant), leading to an energy per unit area that holds for structures from atomic nuclei to clusters of galaxies. Here we explore some of the consequences that arise from such a universal tension.
