  8. FAO and atomic energy

    International Nuclear Information System (INIS)

    1960-01-01

    During the past six years FAO has become more engaged in work concerned with atomic energy. In 1957 it established an Atomic Energy Branch. The new forces and new tools which have become available for use in the fight against poverty, disease and malnutrition can be of the greatest assistance in FAO's work in nearly all phases of the production, storage and distribution of food and other agricultural products. The Organization promotes their use to improve the standards of feeding, clothing and housing throughout the world. Another side of work related to atomic energy is concerned with combating contamination from the use of atomic energy for power production and other purposes. This raises considerable problems for food and agriculture, so that FAO also has a responsibility for assisting Governments in safeguarding their food and food-producing resources from contamination. FAO is essentially concerned with fostering wider knowledge of the many contributions that atomic science can make to agriculture, forestry, fisheries and nutrition. It is also concerned in assisting governments to establish sound programmes for applying atomic science in food and agriculture. One way of spreading such knowledge is through the publication of documents and reports

  13. New ceramic prevents atomic waste leaks, Australian scientists say

    International Nuclear Information System (INIS)

    1991-01-01

    Scientists at the Australian National University say they have invented a material that will safely seal radioactive atomic waste and prevent leaks from occurring for millions for years. Synroc, or synthetic rock, is an advanced ceramic which, when fused with radioactive waste, locks the waste in a crystalline structure, according to a Reuters report. A five kilogram chunk of chemically-inactive synroc is all that is left after 100 litres of radioactive waste is processed. The ceramic was developed in conjunction with the Australian Nuclear Science and Technology Organization and a consortium of four mining companies

  14. Atomic energy review

    International Nuclear Information System (INIS)

    1971-01-01

    The ATOMIC ENERGY REVIEW (AER), a periodical started in 1963 in accordance with the recommendation made by the Scientific Advisory Committee, is now preparing for its tenth year of publication. The journal appears quarterly (ca 900 pages/year) and occasionally has special issues and supplements. From 1963 to 1971 AER developed into an important international high-standard scientific journal which keeps scientists in Member States informed on progress in various fields of nuclear energy. The Agency's specific role of helping 'developing countries to further their science and education' is reflected in the publication policy of the journal. The subject scope of AER, which was determined at the journal's inception, is very broad. It covers topics in experimental and theoretical physics, nuclear electronics and equipment, physics and technology of reactors and reactor materials and fuels, radio-chemistry, and industrial, medical and other uses of radioisotopes. In other words, almost any subject related to the peaceful application of nuclear energy can qualify for inclusion. Specifically, at any particular time the selection criteria for topics are influenced by the Agency's current programme and interests. AER carries comprehensive review articles, critical state-of-the-art and current awareness surveys, and reports on the important meetings organized or sponsored by the Agency. The following four subsections gradually became necessary to do justice to this variety of material: 'Reviews' proper, 'Current Research and Development', 'Special Item' and 'Conferences and Symposia'. Apart from the conference reports, one hundred and twenty-five reviews, almost all of which were published in English to make them accessible to a wide public, have so far been published

  15. ILO and atomic energy

    International Nuclear Information System (INIS)

    1961-01-01

    The work of the International Labour Organisation in the field of atomic energy has been concerned primarily with the protection of the worker against radiation; in this respect it developed the work carried out before the war on the occupational pathology of roentgen ray operators, radium and radioactive substances and uranium. In view of the extremely serious consequences to society and the individual that would result from a neglect of the essential precautions, the ILO has to adopt international standards setting out the essential precautions that should be observed in a work which may entail a radiation hazard. The 44th International Labour Conference, meeting in the summer of 1960, adopted a convention and recommendation on this subject. The Convention applies to all activities involving exposure of workers to ionizing radiations in the course of their work and provides that each Member of the ILO which ratifies it shall undertake to give effect to it by means of laws or regulations, codes of practice or other appropriate means. It further provides that the necessary steps taken at the national level to ensure effective protection should be progressively brought in line with the provisions of the Convention after its ratification

Certain definitions have also been kept. (NEA) [fr

  18. 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...

  19. Advanced technologies and atomic energy

    International Nuclear Information System (INIS)

    1995-01-01

    The expert committee on the research 'Application of advanced technologies to nuclear power' started the activities in fiscal year 1994 as one of the expert research committees of Atomic Energy Society of Japan. The objective of its foundation is to investigate the information on the advanced technologies related to atomic energy and to promote their practice. In this fiscal year, the advanced technologies in the fields of system and safety, materials and measurement were taken up. The second committee meeting was held in March, 1995. In this report, the contents of the lectures at the committee meeting and the symposium are compiled. The topics in the symposium were the meaning of advanced technologies, the advanced technologies and atomic energy, human factors and control and safety systems, robot technology and microtechnology, and functionally gradient materials. Lectures were given at two committee meetings on the development of atomic energy that has come to the turning point, the development of advanced technologies centering around ULSI, the present problems of structural fine ceramics and countermeasures of JFCC, the material analysis using laser plasma soft X-ray, and the fullerene research of advanced technology development in Power Reactor and Nuclear Fuel Development Corporation.

  20. Hidden biases in Australian energy policy

    International Nuclear Information System (INIS)

    Schlaepfer, August

    2009-01-01

    The challenges in developing technology for the capture and storage of CO 2 from coal, oil and gas power generation, as well as those associated with the storage of nuclear waste, are widely regarded as solvable. According to proponents of clean coal, oil and gas technologies, as well as the proponents of nuclear technology, it is only a matter of time and resources to find a solution to their waste problems. Similarly, the Australian Government argues that our main efforts need to be concentrated on clean coal technologies, as well as considering the nuclear option. However, when it comes to the challenges associated with renewable energy technologies, like intermittency of wind generated grid power, storage of electricity from renewable energy and so on, there seems to be an attitude amongst Australian energy planners that these challenges represent insurmountable technical and financial problems, and will, at least in the short to medium term, prevent them from becoming a viable alternative to coal, oil, gas and uranium based energy technologies.

    2016-01-01

    Australian authorities have been traditionally opposed to nuclear energy. The interdiction to build nuclear power plants in the Australian states without the approval of the federal authority was even officially written in the environment code in 1999. Today coal provides 75% of the electricity needs of Australia. Because of climate warming, things are changing, the Australian government is now considering the possibility of using nuclear energy and a site located in southern Australian has been selected for the disposal of low and intermediate level radioactive wastes. In this context the Australian Nuclear Association (ANA) is developing an ambitious program for the promotion of all the applications of nuclear energy through the organisation of conferences and meetings with various experts of nuclear industry. The aim is to make the public aware of the assets of nuclear energy. (A.C.)

  7. Atomic energy indemnification system in Japan

    International Nuclear Information System (INIS)

    Hoshino, Eiichi

    1980-01-01

    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.)

    International Nuclear Information System (INIS)

    1967-01-01

    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

  20. 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.

    Several recent experiments designed to produce and store macroscopic quantities of atomic hydrogen are discussed. The bulk, ground state properties of atomic hydrogen, deuterium, and tritium systems are calculated assuming that all pair interactions occur via the atomic triplet potential. The conditions required to obtain this system, including inhibition of recombination through the energetically favorable singlet interaction, are discussed. The internal energy, pressure, and compressibility are calculated applying the Monte Carlo technique with a quantum mechanical variational wavefunction. The system studied consisted of 32 atoms in a box with periodic boundary conditions. Results show that atomic triplet hydrogen and deuterium remain gaseous at 0 K; i.e., the internal energy is positive at all molar volumes considered.

    The attenuation of scattered thermal energy atomic oxygen is relevant to the potential damage that can occur within a spacecraft which sweeps through atomic oxygen in low Earth orbit (LEO). Although there can be significant oxidation and resulting degradation of polymers and some metals on the external surfaces of spacecraft, there are often openings on a spacecraft such as telescope apertures, vents, and microwave cavities that can allow atomic oxygen to enter and scatter internally to the spacecraft. Atomic oxygen that enters a spacecraft can thermally accommodate and scatter to ultimately react or recombine on surfaces. The atomic oxygen that does enter a spacecraft can be scavenged by use of high erosion yield polymers to reduce its reaction on critical surfaces and materials. Polyoxymethylene and polyethylene can be used as effective atomic oxygen scavenging polymers.

  3. Report of Atomic Energy Group of Advisory Committee for Energy

    International Nuclear Information System (INIS)

    1990-01-01

    The report consists of two chapters. Chapter 1 addresses the present status and future trends in the field of atomic energy. The present conditions of atomic energy development and social background behind them are described first. Features of atomic energy is discussed in relation to its technique-intensive aspect, stability of supply, stability of price, environmental load, and handling of radioactive materials. The relations of these features with energy policies are then discussed, focusing on basic political principles, optimum combination of various energy sources, and the role to be played by atomic energy. This chapter then deals with future trends in atomic energy development efforts and major problems remaining to be solved. Future supply and demand of energy and electric power are discussed. Problems related with atomic energy development are described focusing on some severe conditions depressing the development activities, and measures to be taken immediately. Chapter 2 describes important issues and measures to be taken in the future towards atomic energy development. Discussion is made on safety measures, back-end measures, promotion of location activities, and publicity. (N.K.)

  4. Externalities of energy and atomic power

    International Nuclear Information System (INIS)

    2006-09-01

    Energy technology ensures not only energy supply but also has great impacts on society and environments. Economical value and effect evaluation alone doesn't mean appropriate so the evaluation of 'externalities' should be appreciated. In order to assess atomic power in this context, the Atomic Energy Society of Japan set up a research committee on 'externalities of energy and atomic power' from April 2002 to March 2006, whose activities were described in this report. In addition to environmental effects and environmental externalities, four areas were newly studied as follows: (1) biological effects of low dose rate exposure and externalities, (2) externalities as social/economical effects including stable supply and security, (3) energy technologies evaluation and (4) social choice and decision-making.

    1992-01-01

    This book tells how successive Australian governments pursued the elusive uranium dream. With Australian uranium committed to the West's atomic arsenals, Australia seemed set to become a nation powered by the atom. But by the mid-1950 the Australian government learnt that their expectations were premature, if not unrealistic. The background of the creation of the Australian Atomic Energy Commission is also given along with the examination of the uranium controversies of the 1970s and 1980s. 150 refs

    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.

  5. QED effects on individual atomic orbital energies

    Kozioł, Karol; Aucar, Gustavo A.

    2018-04-01

    Several issues, concerning QED corrections, that are important in precise atomic calculations are presented. The leading QED corrections, self-energy and vacuum polarization, to the orbital energy for selected atoms with 30 ≤ Z ≤ 118 have been calculated. The sum of QED and Breit contributions to the orbital energy is analyzed. It has been found that for ns subshells the Breit and QED contributions are of comparative size, but for np and nd subshells the Breit contribution takes a major part of the QED+Breit sum. It has also, been found that the Breit to leading QED contributions ratio for ns subshells is almost independent of Z. The Z-dependence of QED and Breit+QED contributions per subshell is shown. The fitting coefficients may be used to estimate QED effects on inner molecular orbitals. We present results of our calculations for QED contributions to orbital energy of valence ns-subshell for group 1 and 11 atoms and discuss about the reliability of these numbers by comparing them with experimental first ionization potential data.

  7. Responsibility for atomic energy damages and indemnification

    International Nuclear Information System (INIS)

    Pelzer, N.M.

    1980-01-01

    In the Federal Republic of Germany, the overall regulations on civil responsibility for the damages by nuclear fission or the effect of radiation of radioactive materials were established for the first time in the law concerning peaceful use and protection from danger of atomic energy (hereafter referred to as Atomgesetz) in 1959. Responsibility without error was adopted by German legislators. The liability of the owners of atomic energy facilities (Article 25) was distinguished from that of the possessors of radioactive materials (Article 26) under the law. Facility responsibility (Anlagenhaftung) was limited to 500 million German marks at the maximum. Facility owners had the obligation to offer monetary security of 80 million German marks at the maximum by insurances, etc. When disasters exceeded the amount, the owners were exempted by the state up to the maximum 500 million German marks. The Federal Republic adopted the Paris Agreement in 1975 by a law, and the domestic adjustment of Atomgesetz to the European treaty on atomic energy responsibility was made through the third revision of the Gesetz. According to Article 25-1 of Atomgesetz, the regulations of Paris Agreement are first applied to the owners of atomic energy facilities (operators), and as supplement, Articles 25 to 40 of Atomgesetz are applied. The maximum liability amount is 1,000 million German marks. The demand right of indemnification expires in 3 years after demanders find or are bound to find damages and offenders, and terminates in 30 years regardless of whether the former finds the latter or not. Brussels nuclear ship agreement is applied to nuclear ship owners in Germany (Article 25a, Atomgesetz). (Okada, K.)

    Photoionization of atoms by high energy photons is considered. It is emphasized that in this frequency region the cross section and other characteristics of the process are strongly effected by electron shell polarization and rearrangement effects, including that due to inner vacancy Auger decay. In the effects of nuclear structure could be important and noticeable, i.e. of virtual or real excitation of the nucleus degrees of freedom and of the Quantum Electrodynamics vacuum. Ionization accompanied by secondary photon emission (Compton ionization) is analyzed in the considered domain of energies

  12. Australian energy consumption and production to 2014-15

    International Nuclear Information System (INIS)

    Dickson, A.

    1999-01-01

    The medium to long term outlook for the Australian energy sector is examined, drawing on the ABARE report Australian Energy: Market Developments and Projections to 2014-2015. It is estimated that recent market developments, in particular in the electricity and gas markets, and ongoing policy responses to such things as global climate change, will continue to have profound implications for the energy sector over the medium to longer term. In this environment of uncertainty, high quality and timely information on the future of the energy sector is critical to decision makers. The major input into ABARE's energy projections is the information collected in the biennial fuel and electricity survey. The principal sectors covered by the survey include the mining, manufacturing electricity and gas production sectors. There is also some coverage in the government administration, defence, communications and community services sectors (for example, hospitals and universities). Energy consumption in the sectors not adequately covered by the survey are projected using economic models. These include agriculture, construction, wholesale and retail trade, transport other than rail, finance and insurance, government administration and defence, health and community services, property and business services, cultural and recreational services, personal and other services and residential services. The fuel and electricity survey covers about 5,300 separate establishments in 3,000 organisations. Information is collected on current and expected energy consumption patterns and levels. The projections for these sectors are therefore based on consumers' own expectations about factors that will influence their energy use. Responses to the survey are also supplemented by ABARE projections of the energy requirements of known and planned new projects, such as new minerals processing plants or gas pipelines coming on stream

    Numerical values of the Bethe logarithm for the 1s, 2s, 2p and 3p states in muonic atoms have been computed by assuming a uniform nuclear charge distribution of radius r 0 =1.2Asup(1/3)fm. The accuracy of the results has been checked against several sum rules obeyed by the oscillator strengths. The possible relevance of these results for more realistic models of the charge distribution is also discussed, and the lowest-order Lamb shift correction to muonic energy levels is reexamined

  15. Nuclear energy: salvaging the atomic age

    International Nuclear Information System (INIS)

    Weinberg, A.M.

    1979-01-01

    The history of atomic power is reviewed from the first chain reaction in Chicago in 1942 to the worst-to-date accident at the Three Mile Island power plant in March, 1979. While media coverage during the Three Mile Island incident made the public aware of some reactor hardware and radiation hazards, Weinberg suggests that an acceptable nuclear future should have six characteristics: increased physical isolation of reactors, further technical improvements, separation of generation and distribution, professionalization of the nuclear cadre, heightened security, and public education about the hazards of radiation. Weinberg feels the question of low-level radiation effects to be critical to public acceptance of nuclear energy. Since the effects (if any) are so rarely seen because exposures are so small, the issue may be beyond the ability of science to decipher. Weinberg again explains his reference to nuclear energy as a Faustian Bargain: ''...nuclear energy, that miraculous and quite unsuspected source of energy, demands an unprecedented degree of expertise, attention to detail, and social stability. In return, man has, in the breeder reactor, an inexhaustible energy source.''

The diagnoses and medical processing, to acquire new equipment and to consolidate the maintenance and service of nuclear instrumentation. By means of technical of induced mutations, they have developed agricultural resistant varieties to the environmental conditions. Control of ripeness, genetic improvement of seeds, resistance to the illnesses and efficiency of the agronomic performance. The isotopic techniques of traces have great importance to evaluate the hydric resources, and their risk of contamination with toxic metals and pesticides. Nuclear techniques have been used to obtain information and to deepen in their knowledge. A laboratory of radiology control was established in the Technological Institute of Costa Rica, to give service to the industrial installations. To access the information of this field, the Nuclear Center of Information can be consulted, in the University of Costa Rica. (author) [es

  17. The resilience of Australian wind energy to climate change

    Science.gov (United States)

    Evans, Jason P.; Kay, Merlinde; Prasad, Abhnil; Pitman, Andy

    2018-02-01

    The Paris Agreement limits global average temperature rise to 2 °C and commits to pursuing efforts in limiting warming to 1.5 °C above pre-industrial levels. This will require rapid reductions in the emissions of greenhouse gases and the eventual decarbonisation of the global economy. Wind energy is an established technology to help achieve emissions reductions, with a cumulative global installed capacity of ~486 GW (2016). Focusing on Australia, we assess the future economic viability of wind energy using a 12-member ensemble of high-resolution regional climate simulations forced by Coupled Model Intercomparison Project (CMIP) output. We examine both near future (around 2030) and far future (around 2070) changes. Extractable wind power changes vary across the continent, though the most spatially coherent change is a small but significant decrease across southern regions. The cost of future wind energy generation, measured via the Levelised Cost of Energy (LCOE), increases negligibly in the future in regions with significant existing installed capacity. Technological developments in wind energy generation more than compensate for projected small reductions in wind, decreasing the LCOE by around 30%. These developments ensure viability for existing wind farms, and enhance the economic viability of proposed wind farms in Western Australian and Tasmania. Wind energy is therefore a resilient source of electricity over most of Australia and technological innovation entering the market will open new regions for energy production in the future.

  20. Why atomic energy affects Civil Law

    International Nuclear Information System (INIS)

    Knieper, R.

    1980-01-01

    Based on the decision of July 20, 1979 by the Amtsgericht Stuttgart, which dismissed the complaint filed by the Technische Werke der Stadt Stuttgart (public utility) against electricity boycotters as being unfounded for the time being, the author states that a political function is due to Civil Law. The concrete question is whether political considerations have surpassed the limits of laws and interpretations bound by the basic rights. The relationship between a customer depending on power supply and the supply monopolist exceeds contractual relationship by far since it is a social relationship: it is inescapably embraced by the customer's dependence on power supply and by the customer being subject to research work. Atomic energy is being introduced into law of contract by means of dogmatic crutches - breach of additional obligation under a contract. However, in Civil Law, there are a great number of such means enabling solutions to be corrected which seem to be inadequate. (HSCH) [de

    International Nuclear Information System (INIS)

    1997-01-01

    The 1997 Annual Report is published in a special year for Israel, marking the 50th anniversary of its independece and statehood. From its inception, and the election of a distinguished scientist as its first president, Israel has regarded science and technology as a central pillar for future AEC development and a lever for improved quality of life of its people. The Israel Atomic Energy Commission, which will be celebrating its own anniversary in a few years, has made a modest but significant contribution to the establishment and growth of the technological infrastructure of the country. The first article in this Annual Report focuses attention on yet another aspect of our continuing investigation of the basic properties of technologically interesting and important materials, presented in our 1994 and 1996 Annual Reports. The current entry describes an application of the nuclear Time Differential Perturbed Angular Correlation technique to the study of the structure and properties of metal-hydrogen compounds, of potential interest within the framework of future, environmentally attractive hydrogen-burning energy systems, and in fusion power reactors. The second article also relates to some basic aspects of nuclear fusion. A theoretical study of the behavior and properties of laser-generated hot plasmas resulted in the proposal of a new confinement scheme, in which a plasma generated by circularly polarized laser light is confined in a miniature magnetic bottle created by magnetic fields induced in the plasma by the same light. The paper discusses the conditions under which such confinement and ensuing energy gain may be achieved. Measurements of actual axial magnetic fields generated in plasma by intense circularly polarized laser light are also reported. The third report describes one of our ongoing efforts to improve and streamline the techniques and procedures used in medical applications of radioisotopes.

    1996-01-01

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

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

    Martin, Hugo R.

    2011-01-01

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

  15. Energymark: Empowering individual Australians to reduce their energy consumption

    International Nuclear Information System (INIS)

    Dowd, A.; Ashworth, P.; Carr-Cornish, S.; Stenner, K.

    2012-01-01

    Commitment to increase public awareness of climate change mitigation has risen substantially and so has the appreciation of the impact that comes from voluntary behaviour change. We aimed to test whether a process could be designed that encouraged individuals – from within their existing social networks – to facilitate energy reduction discussions that ultimately changed the way they consumed energy. Our “Energymark” process was grounded in the idea that change is facilitated by several supporting factors including the provision of tailored information, social support, encouragement to set goals, and access to feedback. In this paper we report on the first trial with members of the Australian public. By the end of the trial an average emissions reduction of 20% was reported using a pre- and post-trial carbon calculator incorporating the energy used at home, waste, spending on products and services, beef consumption, and transport. While many identified as climate change aware, and had the socio-economic capacity to make changes, we found that participants of widely varying demographics and dispositions responded to program features, achieving equivalent emissions reductions. This bodes well for the program’s effectiveness and warrants further testing of the impact of voluntary action with social processes such as Energymark. - Highlights: ► Energymark program recognises the importance of voluntary individual behaviour change. ► Key features include the provision of information, social support, goal setting and access to feedback. ► At the end of the process an average individual emissions reduction of 20% was reported. ► Consequential aspects were gaining awareness and information and developing a sense of social responsibility. ► Significant also was participants’ understanding that government has a role to play in mitigation.

    1983-01-01

    The Japan Atomic Industrial Forum Inc. has carried out the investigation and analysis to grasp the actual economic condition of atomic energy industry since 1956. The atomic energy industry in Japan has advanced through the preparation phase of research and development around 1960 and the import of power reactors in the latter half of 1960s, to the period of the practical use of power reactors and the formation of nuclear fuel cycle business after 1970. It encountered difficulties such as the huge investment for research and development, the delay of nuclear power generation project due to the location problem and the unstable market. However, in 1981, the sales of the atomic energy industry exceeded one trillion yen, and its state of income and outgo has improved recently, suggesting that the industry is entering the mature phase. The stagnation of economy and electric power demand, the rising cost of nuclear power generation and other problems affect the future development of the industry. In this report, the course of development of the atomic energy industry in Japan from 1956 to 1981 is summarized on the basis of the investigation into its actual condition. The development of atomic energy market and the trend of the indices related to atomic energy are reported. (Kako, I.)

  20. Neck of public acceptance of atomic energy in Japan

    International Nuclear Information System (INIS)

    Tawara, Soichiro.

    1978-01-01

    Discussion is lacking concerning the public acceptance of atomic energy in Japan. In case of the atomic powered ship Mutsu, an opponent says that the ship carries an atomic bomb, but a member of a support group says that the ship emits soft radiation like a hot spring. This is an example of discussion, and most of discussions are made under the political interest, instead of on the scientific base. In Japan, preparatory negotiations are required in advance to the decision making meeting in most cases. Therefore, most of substantial discussions are not public. Engineers in the nuclear industry can hardly express their opinion concerning the development of atomic energy. Most of the data for discussions are not original, but foreign data. Reasons for the development of atomic energy change case by case. It is necessary to consider that people will decide their opinion according to whether the responsible person is reliable or not. Some people oppose to atomic energy to find a new sense of value. Now, all people are requested to think and discuss the problem of atomic energy calmly. (Kato, T.)

    Approximate analytical expressions are derived for the ionization cross sections in the high- and low-collision-energy limits using the improved impulse approximation based on the assumption that the electron-atom inelastic-scattering amplitude is a function only of the momentum transfer. Both cases of simultaneous excitation and de-excitation of one of the atoms are discussed. The formulas are applied to the collisions between two excited hydrogen atoms and are found very useful for estimating the cross sections in the wide range of collisions energies

    Possible interaction between atomic and hydrogen energy power has been discussed. The analysis of the result held shows that the electrical energy produced by the atomic reactor during the of-load hours can be involved into the process of obtaining hydrogen by electrolysis. In order to optimize the transportation and storage of hydrogen it is proposed to convert it into ammonia. The direct uses of ammonia as a fuel into the internal combustion engine and fuel cells are examined. (authors)

  8. The future of atomic energy; TOPICAL

    International Nuclear Information System (INIS)

    Fermi, E.

    1946-01-01

    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

    The production probability of π-mesonic atom in high-energy nuclear collisions is estimated by a coalescence model. The production cross section is calculated for p + Ne and Ne + Ne systems at 2.1 GeV/A and 5.0 GeV/A beam energy. It is shown that nuclear fragments with larger charge numbers have the advantage in the formation of π-mesonic atoms. The cross section is proportional to Z 3 and of the order of magnitude of 1 ∼ 10 μb in all the above cases. The production cross sections of K-mesonic atoms are also estimated. (author)

The last approach was based on an original package developed for carbon clusters. Atomic migration between consecutive basal planes was described by cluster models of two sheets of carbon atoms. Our contribution presents the theoretical results about atomic and molecular interactions with graphite. It was found for H atom bonding energy the value 2.6 eV, using the largest cluster model. The migration of H atoms above the surface and between consecutive basal planes was simulated by extended calculations of potential energy in each point of a mesh containing 450 points describing a local surface of 0.25 nm 2 . A 3D interpolation approach gives the image of a hypersurface potential energy projection at a given distance to the graphite surface. The semi-quantitative results have indicated two significant facts related to atomic species migration. The first is that H atom has the smallest displacement barrier along C-C bonds at a distance of 1.3 A from the basal plane. In the case of absorbed atoms between graphite basal planes an almost free motion channel has been found parallel to the surface. The interaction potential barrier for H atom collision with graphite surface at the center of the carbon ring has been calculated neglecting surface vibration modes and found to be 5.9 eV . The hyperfine interaction between the electron of hydrogen and the proton has been taken as a measure of the interaction between the incident atom and the target local states. The isotropic hyperfine constant obtained at the level of the semiempiric calculations was found to be 402 Gs at the equilibrium position of H atom above a C atom at a distance of 1.3 A. The corresponding value

    1999-01-01

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

  11. The World Power Conference and atomic energy

    International Nuclear Information System (INIS)

    1962-01-01

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

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

  10. Multipolar electrostatics for proteins: atom-atom electrostatic energies in crambin.

    Science.gov (United States)

    Yuan, Yongna; Mills, Matthew J L; Popelier, Paul L A

    2014-02-15

    Accurate electrostatics necessitates the use of multipole moments centered on nuclei or extra point charges centered away from the nuclei. Here, we follow the former alternative and investigate the convergence behavior of atom-atom electrostatic interactions in the pilot protein crambin. Amino acids are cut out from a Protein Data Bank structure of crambin, as single amino acids, di, or tripeptides, and are then capped with a peptide bond at each side. The atoms in the amino acids are defined through Quantum Chemical Topology (QCT) as finite volume electron density fragments. Atom-atom electrostatic energies are computed by means of a multipole expansion with regular spherical harmonics, up to a total interaction rank of L = ℓA+ ℓB + 1 = 10. The minimum internuclear distance in the convergent region of all the 15 possible types of atom-atom interactions in crambin that were calculated based on single amino acids are close to the values calculated from di and tripeptides. Values obtained at B3LYP/aug-cc-pVTZ and MP2/aug-cc-pVTZ levels are only slightly larger than those calculated at HF/6-31G(d,p) level. This convergence behavior is transferable to the well-known amyloid beta polypeptide Aβ1-42. Moreover, for a selected central atom, the influence of its neighbors on its multipole moments is investigated, and how far away this influence can be ignored is also determined. Finally, the convergence behavior of AMBER becomes closer to that of QCT with increasing internuclear distance. Copyright © 2013 Wiley Periodicals, Inc.

  11. Multiloop atom interferometer measurements of chameleon dark energy in microgravity

    Science.gov (United States)

    Chiow, Sheng-wey; Yu, Nan

    2018-02-01

    Chameleon field is one of the promising candidates of dark energy scalar fields. As in all viable candidate field theories, a screening mechanism is implemented to be consistent with all existing tests of general relativity. The screening effect in the chameleon theory manifests its influence limited only to the thin outer layer of a bulk object, thus producing extra forces orders of magnitude weaker than that of the gravitational force of the bulk. For pointlike particles such as atoms, the depth of screening is larger than the size of the particle, such that the screening mechanism is ineffective and the chameleon force is fully expressed on the atomic test particles. Extra force measurements using atom interferometry are thus much more sensitive than bulk mass based measurements, and indeed have placed the most stringent constraints on the parameters characterizing chameleon field. In this paper, we present a conceptual measurement approach for chameleon force detection using atom interferometry in microgravity, in which multiloop atom interferometers exploit specially designed periodic modulation of chameleon fields. We show that major systematics of the dark energy force measurements, i.e., effects of gravitational forces and their gradients, can be suppressed below all hypothetical chameleon signals in the parameter space of interest.

  12. The No.I. Law (1980) on atomic energy

    International Nuclear Information System (INIS)

    1980-01-01

    The Atomic Energy Law regulates all aspects of the use and application of nuclear energy. The four basic principles of the law are as follows: 1. Nuclear energy can be applied only for peaceful purposes, and this must be promoted by effective international cooperation. 2. The materials, equipment and establishments serving the application of nuclear energy are generally in social ownership. 3. Nuclear energy can be applied only with satisfactory safety precautions, and its uses are determined and regularly controlled by the state. 4. The compensation of the damages caused by nuclear energy applications is regulated by special rules. The enforcement of the law and the direction, control and development of the application of nuclear energy is the responsibility of the Council of Ministers. (R.J.)

    Energy levels of atoms is one of the difficult topics in understanding atomic structure of matter. It appears tobe abstract, theoretical and needs visual representation and images. Hence, in this study a microlesson in teaching the high school chemistry concept on the energy levels of atoms is developed and validated. The researchers utilized backward curriculum design in planning the microlesson to meet the standards of the science K-12 curriculum. The planning process of the microlesson involved a) Identifying the learning competencies in K-12 science curriculum b) write learning objectives c) planning of assessment tools d) making a storyboard e) designing the microlesson and validate and revise the microlesson. The microlesson made use of varied resources in the internet from which the students accessed and collected information about energy levels of atoms. Working in groups, the students synthesized the information on how and why fireworks produce various colors of light through a post card. Findings of the study showed that there was an increase of achievement in learning the content and the students were highly motivated to learn chemistry. Furthermore, the students perceived that the microlesson helped them to understand the chemistry concept through the use of appropriate multimedia activities.

  14. Utilization of atomic energy in Asia and nuclear nonproliferation system

    International Nuclear Information System (INIS)

    Ishii, Makoto

    1995-01-01

    The economical growth in East Asia is conspicuous as it was called East Asian Miracle, and also the demand of energy increased rapidly. The end of Cold War created the condition for the further development in this district. Many countries advanced positively the plan of atomic energy utilization, and it can be said that the smooth progress of atomic energy utilization is the key for the continuous growth in this district in view of the restriction of petroleum resources and its price rise in future and the deterioration of global environment. The nuclear nonproliferation treaty (NPT) has accomplished large role, but also its limitation became clear. At present, there is not the local security system in Asia, but in order that the various countries in Asia make the utilization of atomic energy and the security compatible, it is useful to jointly develop safety technology, execute security measures and form the nuclear fuel cycle as Asia. Energy and environmental problems in Asia are reported. Threat is essentially intention and capability, and the regulation only by capability regardless of intention brings about unrealistic result. The limitation of the NPT is discussed. The international relation of interdependence deepends after Cold War, and the security in Asia after Cold War is considered. As the mechanism of forming the nuclear fuel cycle for whole Asia, it is desirable to realize ASIATOM by accumulating the results of possible cooperation. (K.I.)

    1980-01-01

    The polarizability and nuclear-polarization energy shifts of nuclei composed of closed shells plus valence nucleons in muonic atoms have been calculated: the harmonic-oscillator results of the El polarizability and the energy shifts have been corrected by means of a perturbative approach, which takes into account the effects introduced by the deformation Nilsson potential. Furthermore, to take into account the core polarization effect, different harmonic-oscillator parameters for the core and the valence nucleons have been assumed. The energy shifts of a sequence of states occupied by the muon during its atomic electromagnetic cascade for the nuclei 17 O and 17 F, 41 Ca and 41 Sc have been calculated. (author)

  17. Low-energy positron interactions with atoms and molecules

    International Nuclear Information System (INIS)

    Surko, C M; Gribakin, G F; Buckman, S J

    2005-01-01

    This paper is a review of low-energy positron interactions with atoms and molecules. Processes of interest include elastic scattering, electronic and vibrational excitation, ionization, positronium formation and annihilation. An overview is presented of the currently available theoretical and experimental techniques to study these phenomena, including the use of trap-based positron beam sources to study collision processes with improved energy resolution. State-resolved measurements of electronic and vibrational excitation cross sections and measurement of annihilation rates in atoms and molecules as a function of incident positron energy are discussed. Where data are available, comparisons are made with analogous electron scattering cross sections. Resonance phenomena, common in electron scattering, appear to be less common in positron scattering. Possible exceptions include the sharp onsets of positron-impact electronic and vibrational excitation of selected molecules. Recent energy-resolved studies of positron annihilation in hydrocarbons containing more than a few carbon atoms provide direct evidence that vibrational Feshbach resonances underpin the anomalously large annihilation rates observed for many polyatomic species. We discuss open questions regarding this process in larger molecules, as well as positron annihilation in smaller molecules where the theoretical picture is less clear. (topical review)

    Manipulating the structure and the dynamics of metallic nanoparticles, attractive due to their optical, electronic and magnetic properties, including applications in catalysis, requires a fundamental understanding of the dynamic processes at the atomic level. The fundamental mechanism of catalysis at the atomic scale has already been proposed and demonstrated in Au, Pd and Au-Pd catalysis of H2O2 through the scrutiny of low energy electron elastic total cross sections (TCSs). The use of mixed precious metal catalysts can produce even higher activities compared to Au alone. Here the interplay between negative ion resonances and Ramsauer-Townsend minima that characterize low energy electron TCSs for Au is identified as the fundamental signature of nanoscale catalysts. Calculated electron elastic TCSs for Ag, Pt, Pd, Ru and Y atoms are presented as illustrations. The recent complex angular momentum methodology is used for the calculations. It is concluded that these atoms are suitable candidates for nanocatalysts individually or in combinations. Supported by U.S. DOE, AFOSR and CAU CFNM, NSF-CREST.

    To evaluate the impact of changing energy prices on Australian ambulance systems. Generalised estimating equations were used to analyse contemporaneous and lagged relationships between changes in energy prices and ambulance system performance measures in all Australian State/Territory ambulance systems for the years 2000-2010. Measures included: expenditures per response; labour-to-total expenditure ratio; full-time equivalent employees (FTE) per 10,000 responses; average salary; median and 90th percentile response time; and injury compensation claims. Energy price data included State average diesel price, State average electricity price, and world crude oil price. Changes in diesel prices were inversely associated with changes in salaries, and positively associated with changes in ambulance response times; changes in oil prices were also inversely associated with changes in salaries, as well with staffing levels and expenditures per ambulance response. Changes in electricity prices were positively associated with changes in expenditures per response and changes in salaries; they were also positively associated with changes in injury compensation claims per 100 FTE. Changes in energy prices are associated with changes in Australian ambulance systems' resource, performance and safety characteristics in ways that could affect both patients and personnel. Further research is needed to explore the mechanisms of, and strategies for mitigating, these impacts. The impacts of energy prices on other aspects of the health system should also be investigated. © 2013 The Authors. ANZJPH © 2013 Public Health Association of Australia.

    Single atom localization and identification is crucial in understanding effects which depend on the specific local environment of atoms. In advanced nanometer scale materials, the characteristics of individual atoms may play an important role. Here, we describe spectroscopic experiments (electron energy loss spectroscopy, EELS, and Energy Dispersed X-ray spectroscopy, EDX) using a low voltage transmission electron microscope designed towards single atom analysis. For EELS, we discuss the advantages of using lower primary electron energy (30 keV and 60 keV) and higher energy losses (above 800 eV). The effect of atomic movement is considered. Finally, we discuss the possibility of using atomically resolved EELS and EDX data to measure the fluorescence yield for X-ray emission. Copyright © 2015 Elsevier B.V. All rights reserved.

    Low-energy neutral atom (LENA) imaging promise to be a revolutionary tool for global imaging of space plasmas. The technical challenges of LENA detection include separating them from the intense ambient UV without losing information about their incident trajectories, quantifying their trajectories, and obtaining high-sensitivity measurements. Two techniques that have been proposed for this purpose are based on fundamentally different atomic interaction mechanisms between LENAs and a solid; LENA transmission through an ultra thin foil and LENA reflection from a solid surface. Both of these methods provide LENA ionization (for subsequent removal from the UV by electrostatic deflection) and secondary electron emission (for time-of-flight start pulse generation and/or coincidence). They present a comparative study of the transmission and reflection techniques based on differences in atomic interactions with solids and surfaces. Transmission methods are shown to be superior for secondary electron emission rather than reflection methods. Furthermore, transmission methods are shown to be a sufficient for LENA imaging at LENA energies of approximately 1 keV to greater than 30 keV. A hybrid instrument using reflection from a low work function surface for LENA ionization and transmission for secondary electron emission is optimal for imaging of LENAs with energies less than approximately 1 keV

  16. Plasma screening effects on the energies of hydrogen atom

    A more general exponential cosine screened Coulomb potential is used for the first time to investigate the screening effects on the hydrogen atom in plasmas. This potential is examined for four different cases that correspond to four different type potentials when the different parameters are used in the potential within the framework of the well-known asymptotic iteration method. By solving the corresponding the radial Schrödinger equation with the screened and exponential cosine screened Coulomb potentials and comparing the obtained energy eigenvalues with the results of other studies, the applicability of the method to this kind of plasma physics problem is shown. The energy values of more general exponential cosine screened Coulomb potential are presented for various parameters in the potential. One of the advantages of the present potential is that it exhibits stronger screening effect than that of the exponential cosine screened Coulomb potential and it is also reduced to screened Coulomb and exponential cosine screened Coulomb as well as Coulomb potentials for special values of parameters. The parameters in the potential would be useful to model screening effects which cause an increase or decrease in the energy values of hydrogen atom in both Debye and quantum plasmas and in this manner this potential would be useful for the investigations of the atomic structure and collisions in plasmas.

    Two of the working sessions of the meeting were devoted to aspects of international atomic energy law; the international character of the meeting was also reflected by the home countries of the members of the panel discussion concluding the working sessions. There was substantial reason to put emphasis on the international dimension of the topics discussed. In June 1994, the Nuclear Safety Convention had been signed in Vienna by diplomatic representatives of the signatory countries, and this Convention marks a signpost in the history of international atomic energy law. At the time the meeting was held, negotiations for improving the international nuclear lability law, which had been dragging on since 1989, had come to a stalemate. The meeting offered a suitable forum for taking a scientific approach to tackle the complex problems involved in reshaping the law on nuclear safety and nuclear liability. The third working session of the meeting has been discussing topics relating to the implementation of the German Atomgesetz (Atomic Energy Act). (orig./HP) [de

    Full Text Available Fossil fuel is not practically renewable and therefore the world is at risk of fossil fuel depletion. This gives urgency to investigate alternative energies, especially for industries that rely entirely on energies for operations, such as offshore industry. The use of alternative energies in this industry has been in place for a while now. This paper discusses the application of various alternative energy sources to assist powering the Goodwyn Alpha (A Platform, located on the North West Shelf (NWS of Australia. The three alternative energy sources under discussion are: wind, wave and solar. The extraction devices used are the Horizontal and Vertical-Axis Wind Turbines - for wind; Pelamis, PowerBuoy and Wave Dragon - for wave; and the solar parabolic dish of SunBeam and Photovoltaic (PV cells of SunPower - for solar. These types of devices are installed within the same offshore platform area. Technical, environmental and economic aspects are taken into consideration before the best selection is made. The results showed that PowerBuoy used for wave energy, is the best device to be used on offshore platforms where operators could save up to 9% of power; $603,083 of natural gas; and 10,848 tonnes of CO2 per year.

    Imaging of the terrestrial magnetosphere is possible through the detection of low-energy neutral atoms (LENAs) produced by charge exchange between magnetospheric plasma ions and neutral atoms of the Earth's geocorona. The authors present calculations of both hydrogen and oxygen line-of-sight LENA fluxes expected on orbit for various plasma regimes as predicted by the Rice University Magnetospheric Specification Model. To decrease the required computation time, they are in the process of adapting their code for massively parallel computers. The speed gains achieved from parallel algorithms are substantial, and they present results from computational runs on the Connection Machine CM-2 data parallel supercomputer. They also estimate expected image count rates and image quality based on realistic instrument geometric factors, energy passbands, neutral atom scattering in the instrument, and image accumulation intervals. The results indicate that LENA imaging instruments will need a geometric factor (G) on the order of 0.1 cm 2 sr eV/eV to be capable of imaging storm time ring currents, and a G of 1.0 cm 2 sr eV/eV in order to image the quiet time ring current fluxes, ion injections from the tail, and subsequent ion drifts toward the dayside magnetopause

    It is hypothesized that the observed proliferation of energy-dense, nutrient-poor foods globally is an important contributing factor to the development of the obesity epidemic. However, evidence that the population's dietary energy density has increased is sparse. The World Cancer Research Fund recommends that dietary energy density be energy density of the Australian population has changed between 1995 and 2012. A secondary analysis of two cross-sectional Australian national nutrition surveys from 1995 and 2011/2012 was conducted. Participants of the surveys included adults aged 18 years and older (1995 n=10,986 and 2011/2012 n=9,435) completing 24-hour dietary recalls, including a second recall for a subset of the population (10.4% in 1995 and 64.6% in 2011/2012). Outcome measures included the change in dietary energy density (calculated as energy/weight of food [kcal/g] for food only) between surveys. The National Cancer Institute method for "estimating ratios of two dietary components that are consumed nearly every day" was used to determine the usual distribution and the percentage of participants reporting energy density energy density was 1.59 (0.26) kcal/g and 1.64 (0.32) kcal/g (Penergy-density recommendations. For those aged 70 years and older, the percentage with energy density energy density energy density has increased between the two surveys and few people consumed low energy-dense diets in line with recommendations. The change was largely due to increased energy density of older adult's diets, while young adults had high dietary energy density at both time points. These data suggest efforts now focus on the evaluation of the role of modifying energy density of the diet to reduce the risk of weight gain in adults.

    2010-07-01

    This paper reported on a study in which a life cycle assessment (LCA) of cotton production in Australia was conducted to evaluate energy use and greenhouse gas (GHG) emissions from tillage to export shipping. The study showed that on-farm indirect cotton-farming is the most energy consuming component, consuming nearly 32.36 GJ/ha of energy. On-farm indirect cotton-farming is the most GHG emitting component, emitting about 1.64 tonne of carbon dioxide (CO{sub 2})/ha. Energy use and the emissions by off-farm direct cotton-farming were calculated as 5.09 GJ/ha and 0.14 tonne CO{sub 2}/ha respectively. Energy consumed by off-farm indirect farming was found to be 0.036 GJ/ha or 0.002 tonne CO{sub 2}/ha. The total energy usage and greenhouse gas emissions in the Australian cotton farming system were estimated to be 46.43 GJ/ha and 2.42 tonnes CO{sub 2}/ha for on-farm, and 5.13 GJ/ha and 0.145 tonne CO{sub 2}/ha for the off-farm sections. In total, after including emissions caused by nitrogen based fertilizers, 51.57 GJ/ha of energy is used and 2.86 tonnes CO{sub 2}/ha is emitted by a typical Australian cotton farming system from tillage to export shipping.

    Imaging of the terrestrial magnetosphere can be performed by detection of low energy neutral atoms (LENAs) that are produced by charge exchange between magnetospheric plasma ions and cold neutral atoms of the Earth's geocorona. As a result of recent instrumentation advances it is now feasible to make energy-resolved measurements of LENAs from less than I key to greater than 30 key. To model expected LENA fluxes at a spacecraft, we initially used a simplistic, spherically symmetric magnetospheric plasma model. 6 We now present improved calculations of both hydrogen and oxygen line-of-sight LENA fluxes expected on orbit for various plasma regimes as predicted by the Rice University Magnetospheric Specification Model. We also estimate expected image count rates based on realistic instrument geometric factors, energy passbands, and image accumulation intervals. The results indicate that presently proposed LENA instruments are capable of imaging of storm time ring current and potentially even quiet time ring current fluxes, and that phenomena such as ion injections from the tail and subsequent drifts toward the dayside magnetopause may also be deduced

  12. Nuclear energy: fusion and fission - From the atomic nucleus to energy

    International Nuclear Information System (INIS)

    2002-09-01

    Matter is made up of atoms. In 1912, the English physicist Ernest Rutherford (who had shown that the atom had a nucleus), and the Danish physicist Niels Bohr developed a model in which the atom was made up of a positively charged nucleus surrounded by a cloud of electrons. In 1913, Rutherford discovered the proton, and in 1932, the English physicist Chadwick discovered the neutron. In 1938, Hahn and Strassmann discovered spontaneous fission and the French physicist Frederic Joliot-Curie, assisted by Lew Kowarski and Hans Von Halban, showed in 1939 that splitting uranium nuclei caused an intense release of heat. The discovery of the chain reaction would enable the exploitation of nuclear energy. 'It was the Second World War leaders who, by encouraging research for military purposes, contributed to the development of nuclear energy'. During the Second World War, from 1939 to 1945, studies of fission continued in the United States, with the participation of emigre physicists. The Manhattan project was launched, the aim of which was to provide the country with a nuclear weapon (used at Hiroshima and Nagasaki in 1945). After the war ended, research into energy production by the nuclear fission reaction continued for civil purposes. CEA (the French Atomic Energy Commission) was set up in France in 1945 under the impetus of General de Gaulle. This public research body is responsible for giving France mastery of the atom in the research, health, energy, industrial, safety and defense sectors. (authors)

    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

    2016-02-01

    To estimate: 1) daily energy deficit required to reduce the weight of overweight children to within normal range; 2) time required to reach normal weight for a proposed achievable (small) target energy deficit of 0.42 MJ/day; 3) impact that such an effect may have on prevalence of childhood overweight. Body mass index and fitness were measured in 31,424 Australian school children aged between 4.5 and 15 years. The daily energy deficit required to reduce weight to within normal range for the 7,747 (24.7%) overweight children was estimated. Further, for a proposed achievable target energy deficit of 0.42 MJ/day, the time required to reach normal weight was estimated. About 18% of children were overweight and 6.6% obese; 69% were either sedentary or light active. If an energy deficit of 0.42 MJ/day could be achieved, 60% of overweight children would reach normal weight and the current prevalence of overweight of 24.7% (24.2%-25.1%) would be reduced to 9.2% (8.9%-9.6%) within about 15 months. The prevalence of overweight in Australian school children could be reduced significantly within one year if even a small daily energy deficit could be achieved by children currently classified as overweight or obese. © 2015 The Authors.

  7. Recent developments at the atomic and molecular data unit of the International Atomic Energy Agency

    2002-01-01

    The Atomic and Molecular (A+M) Data Unit of the IAEA main purpose is to establish and maintain databases in support of nuclear fusion energy research. This encompasses a very large number of processes in atomic, molecular, and plasma - material interaction physics. Recent improvements and additions to these databases are presented. A prototype search engine, which searches five different sites for radiative data and two sites for electron impact excitation and ionization data is introduced. It is available at the IAEA, Weizmann Institute and GAPHYOR web sites. Data on erosion materials produced by the Co-ordinated research project (CRP) 'Plasma-interaction induced erosion of fusion reactor materials' was evaluated, fitted to physically realistic forms for angle and energy dependence and the resulting fits were added to the online electronic database. In a CRP on radiative power losses in plasmas, many lenghtly modelling calculations were carried out. In addition to providing the calculated radiated power, effective ionisation and recombination rate coefficients were derived. These data were stored along with the populations of the ion stages as well as the total radiation from each ion stage. Thus, it is possible to use these data to interpolate in temperature and electron density to obtain the radiated power at an arbitrary temperature and density. A preliminary version of a new interface to the bibliographic database at the A+M Data unit was developed, it allows the user to search by author and/or keyword. The resulting references are displayed along with a link to the home page of the journal where possible. A code for calculation electron impact excitation cross sections using the so-called 'average approximation' and a version of the Hartree-Fock atomic structure code were installed in the unit and can be run through an interface at the web page.

    2008-03-01

    To measure the types and quantities of energy-dense, nutrient-poor 'extra' foods consumed by Australian children and adolescents and their contribution to total energy and nutrient intakes. We used data from 3007 children, aged 2-18 years, who participated in the nationally representative 1995 National Nutrition Survey. Intake was determined by 24-h recall and 'extra' foods were defined using principles outlined in the Australian Guide to Healthy Eating (AGHE) and by applying cut points for maximum amounts of fat and sugar within each food category. All children (99.8%) consumed at least one 'extra' food and the most commonly consumed were margarine, sugar-sweetened soft drinks, cordials and sugar. 'Extra' foods contributed 41% of daily energy intake. Those foods contributing most to energy intake were fried potatoes (4.2%), sugar-sweetened soft drinks (3.3%), ice cream/ice confection (3.1%) and cordials (2.7%). Age and sex were important determinants of 'extra' food intake, with males and older children generally consuming more and different types of, 'extra' foods than females and younger children. 'Extra' foods contributed 19% protein, 47% total fat, 47% saturated fat, 54% sugar, and approximately 20-25% of selected micronutrients to the diet. Calcium and zinc intakes from core foods were below 70% of the recommended dietary intakes for adolescent girls. 'Extra' foods are over-consumed at two to four times the recommended limits and contribute excessively to the energy, fat and sugar intakes of Australian children, while providing relatively few micronutrients. This is of concern in terms of children's weight and nutrient status.

    To identify the types and quantities of 'extra' foods, or energy-dense, nutrient-poor foods, consumed by Australian adults, and assess their contribution to total energy and nutrient intakes. We used 24-h recall data from 10 851 adults, aged 19 years and over, who participated in the nationally representative 1995 National Nutrition Survey. 'Extra' foods were defined using principles outlined in the Australian Guide to Healthy Eating and by applying cut points for maximum amounts of fat and sugar within each food category. 'Extra' foods contributed to 36% of daily energy intake with the highest contributors being fried potatoes (2.8%), margarine (2.6%), cakes and muffins (2.5%), beer (2.4%), sugar-sweetened soft drinks (2.4%), and meat pies (2.2%). Both age and sex were important determinants of 'extra' foods intake; younger adults were more likely to consume sugar-sweetened soft drinks, fried potatoes, meat pies and savoury pastries, pizza, crisps, lollies and chocolate; whereas older adults were more likely to consume sweet and savoury biscuits, cakes and muffins, margarine and butter. In all age groups, 'extra' foods contributed more to energy intake for men than women. Overall, 'extra' foods contributed 16% protein, 41% total fat, 41% saturated fat, 47% sugar and approximately 20% of selected micronutrients to the diet. 'Extra' foods contribute excessively to the energy, fat and sugar intakes of Australian adults, while providing relatively few micronutrients. This is of concern for the increasing risk of overweight and chronic disease and poor micronutrient status.

    The Hanford Site has hosted similar activities, including both Hanford Summits I and II. The Hanford Summits were two-day televised events to discuss the commitment of the current Presidential administration to the environmental restoration of the Hanford Site. Public involvement and strategic issues established from Hanford Summit I include: Regulatory issues, training and education, economic development and partnership, and technology transfer. Hanford Summit II provided a summary of how Secretary of Energy O'Leary is proceeding on the above strategic issues. The DOE and Westinghouse School for Environmental Excellence frequently offers a six-week course for environmental professionals and workers. Approximately thirty to forty individuals attend the training course, which provides training in environmental regulation compliance. The Hanford Site has hosted two previous International Atomic Energy Agency training courses. The courses lasted two weeks and had approximately eight to ten participants. Nuclear Material Management and Neutron Monitoring were the courses hosted by the Hanford Site

    If dark energy, which drives the accelerated expansion of the universe, consists of a light scalar field, it might be detectable as a "fifth force" between normal-matter objects, in potential conflict with precision tests of gravity. Chameleon fields and other theories with screening mechanisms, however, can evade these tests by suppressing the forces in regions of high density, such as the laboratory. Using a cesium matter-wave interferometer near a spherical mass in an ultrahigh-vacuum chamber, we reduced the screening mechanism by probing the field with individual atoms rather than with bulk matter. We thereby constrained a wide class of dark energy theories, including a range of chameleon and other theories that reproduce the observed cosmic acceleration.

    2010-01-01

    The Hungarian Atomic Energy Authority (HAEA) is authorised by the prescriptions of the law on Atomic Energy to support research and development activities in those scientific and technical areas, which primarily contribute to performing the nuclear safety regulatory responsibility and improving effectiveness and efficiency of licensing, inspection and assessment activities. HAEA's Research and Development program is an essential one: it is run on significant financial resources and with the involvement of a wide range of Technical Support Organisations (TSO). Therefore appropriate priorities have to be applied and directions have to be followed when decisions are made on activities to be supported by the HAEA. These priorities and strategic directions for the R and D activities are defined in the Research and Development Policy of HAEA, which was lastly revised in 2008. The report introduces the summary evaluation and major results of R and D activities sponsored by the HAEA in the previous 2005-2008 cycle and the directions and general elements of the R and D Policy of the ongoing period 2009-2012.

    Pelzer, N.

    1982-01-01

    The liability of operators of nuclear installations in the FRG is limited under current law to the sum of one thousand million DM (section 31 of the Atomic Energy law). Since about the autumn of 1979, the Federal Ministry of the Interior is making inquiries into the necessity and appropriateness of abandoning the provision on liability limitations, in order to improve the victims compensation. The legal problems involved in this decision are presented by the author, trying to answer the question of whether the current system of liability limitations should be maintained or abandoned by discussing this issue from the point of view of the legal functions ''justice'' and ''expedience'' of this provision. The manifold international interlacement of the atomic energy law does not allow this study to be restricted to the law of the FRG. A brief review of the development and current state of the international nuclear liability law is the basis of this study into the problems of a possible modification of the German nuclear liability provisions. The study is carried out with the purpose of elaborating model solutions. (orig./HP) [de

    Imaging of the space plasma environment via low-energy neutral atoms (LENAs) promises to revolutionize the way in which large-scale space plasma phenomena are viewed and understood. LENAs are produced by charge exchange between plasma ions (less than tens of kilo-electron-volts) and cold geocoronal neutrals; these LENAs radiate outward in all directions from their points of origin. Previously developed methods for imaging higher energy neutrals are not suitable for observing the majority of the terrestrial magnetosphere, which is comprised primarily of lower energy plasma populations. This paper briefly describes both the direct and indirect techniques that have been suggested for imaging LENAs to date. The authors then examine in more detail the most advanced of these techniques appropriate for magnetospheric imaging, indirect detection based on ionization of LENAs as they transit ultra thin foils. Such a LENA imager consists of four basic components: (1) a biased collimator to remove the ambient charged particles and set the azimuthal field of view; (2) an ultra thin foil, which ionizes a portion of the incident LENAs; (3) an electrostatic analyzer to reject UV light and set the energy passband; and (4) a coincidence position detector to measure converted LENAs while rejecting noise and penetrating radiation

    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

  1. Distributional effects of the Australian Renewable Energy Target (RET) through wholesale and retail electricity price impacts

    International Nuclear Information System (INIS)

    Cludius, Johanna; Forrest, Sam; MacGill, Iain

    2014-01-01

    The Australian Renewable Energy Target (RET) has spurred significant investment in renewable electricity generation, notably wind power, over the past decade. This paper considers distributional implications of the RET for different energy users. Using time-series regression, we show that the increasing amount of wind energy has placed considerable downward pressure on wholesale electricity prices through the so-called merit order effect. On the other hand, RET costs are passed on to consumers in the form of retail electricity price premiums. Our findings highlight likely significant redistributive transfers between different energy user classes under current RET arrangements. In particular, some energy-intensive industries are benefiting from lower wholesale electricity prices whilst being largely exempted from contributing to the costs of the scheme. By contrast, many households are paying significant RET pass through costs whilst not necessarily benefiting from lower wholesale prices. A more equitable distribution of RET costs and benefits could be achieved by reviewing the scope and extent of industry exemptions and ensuring that methodologies to estimate wholesale price components in regulated electricity tariffs reflect more closely actual market conditions. More generally, these findings support the growing international appreciation that policy makers need to integrate distributional assessments into policy design and implementation. - Highlights: • The Australian RET has complex yet important distributional impacts on different energy users. • Likely wealth transfers from residential and small business consumers to large energy-intensive industry. • Merit order effects of wind likely overcompensate exempt industry for contribution to RET costs. • RET costs for households could be reduced if merit order effects were adequately passed through. • Need for distributional impact assessments when designing and implementing clean energy policy

  5. AlintaGas perspective on evolving competition in the Western Australian energy market

    International Nuclear Information System (INIS)

    Harvey, Ph.

    1999-01-01

    The author discusses the evolving competition in the Western Australian energy market, with a clear focus on gas. Before considering the future energy market, he puts today's market in perspective and set the framework within which the development of the future markets should be considered. What is a competitive market? It is a market where there are enough producers and enough users for competition between them to determine prices, which are set prices, not costs. An example of a competitive gas market in Western Australia is the Pilbara. There are enough producers and enough users in the Pilbara area that gas prices are set by the normal forces of supply and demand and transport costs are essentially negligible. There is no need for regulation or any external price setting - the forces of supply and demand determine prices. In the south west gas market there are the same gas suppliers, but a different and larger group of customers. This market differs from the Pilbara market because now there are transport costs involved. The transport element is a natural monopoly - and it is important to ensure transport prices do not distort the competitive market established between producers and users. Hence, third party access to the Dampier to Bunbury Natural Gas Pipeline (DBNGP), under properly regulated access arrangements to ensure there is no market distortion, allows the forces of competition to set prices in the south west gas market. Western Australia is fortunate - and unique among the Australian states - in that it has a number of gas producers keen to sell into Western Australian gas markets. Hence, gas on gas competition - as well as inter-fuel competition - is setting prices. For historic reasons - and they are good reasons - energy markets in Western Australia are not yet completely open. There is however a program of market deregulation that commenced on I January 1995 and will be completed on July 2002, which means that all gas customers, even residential

  6. Energy dissipation unveils atomic displacement in the noncontact atomic force microscopy imaging of Si(111 )-(7 ×7 )

    The kinetic energy of the oscillating cantilever of noncontact atomic force microscopy (nc-AFM) at room temperature was considerably dissipated over regions between a Si adatom and its neighboring rest atom for Si(111 )-(7 ×7 ) in close proximity to a Si tip on the cantilever. However, nc-AFM topographic images showed no atomic features over those regions, which were the hollow sites of the (7 ×7 ). This energy dissipation likely originated from displacement of Si adatoms with respect to the tip over the hollow sites, leading to a lateral shift of the adatoms toward the rest atom. This interaction led to hysteresis over each cantilever oscillation cycle; when the tip was retracted, the Si adatom likely returned to its original position. To confirm the atomic processes involved in the force interactions through Si dangling bonds, the Si(111 )-(7 ×7 ) surface was partly terminated with atomic hydrogen (H) and examined by nc-AFM. When the Si adatoms and/or the rest atoms were terminated with H, the hollow sites were not bright (less dissipation) in images of the energy dissipation channels by nc-AFM. The hollow sites acted as metastable sites for Si adatoms in surface diffusion and atom manipulation; thus, the dissipation energy which is saturated on the tip likely corresponds to the difference in the potential energy between the hollow site and the Si adatom site. In this study, we demonstrated the ability of dissipation channels of nc-AFM to enable visualization of the dynamics of atoms and molecules on surfaces, which cannot be revealed by nc-AFM topographic images alone.

  7. Higher order corrections to energy levels of muonic atoms

    International Nuclear Information System (INIS)

    Rinker, G.A. Jr.; Steffen, R.M.

    1975-08-01

    In order to facilitate the analysis of muonic x-ray spectra, the results of numerical computations of all higher order quantum electrodynamical corrections to the energy levels of muonic atoms are presented in tabular and graphical form. These corrections include the vacuum polarization corrections caused by emission and reabsorption of virtual electron pairs to all orders, including ''double-bubble'' and ''cracked-egg'' diagrams. An estimate of the Delbruecke scattering-type correction is presented. The Lamb-shift (second- and fourth-order vertex) corrections have been calculated including the correction for the anomalous magnetic moment of the muon. The relativistic nuclear motion (or recoil) correction as well as the correction caused by the screening of the atomic electrons is presented in graphs. For the sake of completeness a graph of the nuclear polarization as computed on the basis of Chen's approach has been included. All calculations were made with a two-parameter Fermi distribution of the nuclear charge density. 7 figures, 23 references

  8. Inevitability of atomic energy in India's power programme

    International Nuclear Information System (INIS)

    Ramanna, R.

    1977-01-01

    The case for atomic energy as the inevitable answer to the energy problem of India has been emphatically put up and supported with data. Hydroelectric power is costly to develop and moreover its potential is not enough to meet India's growing energy requirements. On the grounds of economics and safety, nuclear power has been shown to be superior to power from coal-based power plants. India's proved reserves of coal are 21 billion tonnes out of which 80% has ash content more than 20% and in order to reach only half of the present per capita energy consumption in Europe, the present output of 90 million tonnes/year of coal will have to be increased by a factor of 10, which in addition raises the problem of its transportation to the plant sites. Secondly, total energy from the available coal is estimated at 160 x 10 12 kwh, while that from known reserves of 52,000 tonnes of uranium is 7.2 x 10 12 kwh if used in thermal reactors and 208 x 10 12 kwh if used in fast reactors. Thorium with its known reserves of 320,000 tonnes would give another 1280 x 10 12 kwh. As for safety and ecology, it has been pointed out that : (1) in U.S., the number of coal miners dying of black cancer is 1000 per 10 12 kwh of electricity generated, whereas the fatality rate of uranium miners due to lung cancer is 20 per 10 12 kwh of electricity generated and (2) safety has been the primary concern in all aspects of nuclear technology - mining, fuel production, reactor operation and radioactive waste processing. It has also been explained how the fear of any terrorist getting possession of plutonium for spreading it into atmosphere or making a nuclear bomb is highly improbable, because at any point throughout the fuel cycle plutonium is under strict security surveillance and it is impossible to make a nuclear device without the back-up of powerful laboratory facilities. Finally, India's three stage atomic power programme is described in brief. (M.G.B.)

  10. Spontaneous emission and scattering in a two-atom system: Conservation of probability and energy

    International Nuclear Information System (INIS)

    Berman, P. R.

    2007-01-01

    An explicit calculation of conservation of probability and energy in a two-atom system is presented. One of the atoms is excited initially and undergoes spontaneous emission. The field radiated by this atom can be scattered by the second atom. It is seen that the Weisskopf-Wigner approximation must be applied using a specific prescription to guarantee conservation of probability and energy. Moreover, for consistency, it is necessary to take into account the rescattering by the source atom of radiation scattered by the second atom

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

    International Nuclear Information System (INIS)

    Duncan, R.M.

    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)

    1990-01-01

    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

    1989-01-01

    The International Atomic energy Agency (IAEA) is developing an integrated information base that will systematically cover the technical, regulatory, radiation protection, planning, and economic aspects related to the decontamination and decommissioning (D/D) of nuclear facilities. The object of this program is to assist member states in developing the required expertise, equipment, and programs so that they can decommission their nuclear facilities in a safe, timely, and cost-effective manner. In addition to providing information, the IAEA encourages research and provides technical assistance in the form of expert missions, equipment design and procurement, etc., to assist member states in implementing their D/D programs. The technology contained in some recent IAEA reports is reviewed, including the decontamination, segmentation, and demolition of concrete and steel; the recycle/reuse of components from decommissioning; and the reduction of occupational exposures in D/D and the regulatory process in decommissioning. The IAEA's future program is briefly reviewed

    1987-12-01

    The Safeguards Department of the International Atomic Energy Agency (IAEA) conducts inspections to assure the peaceful use of a state's nuclear materials and facilities. Because of limited resources for conducting inspections, the careful disposition of inspection effort among these facilities is essential if the IAEA is to attain its safeguards goals. This report describes an optimization procedure for assigning an inspection effort to maximize attainment of IAEA goals. The procedure does not require quantitative estimates of safeguards effectiveness, material value, or facility importance. Instead, the optimization is based on qualitative, relative prioritizations of inspection activities and materials to be safeguarded. This allocation framework is applicable to an arbitrary group of facilities such as a state's fuel cycle, the facilities inspected by an operations division, or all of the facilities inspected by the IAEA

    Low-energy accelerators have in the past produced a major part of our current knowledge of nuclear physics. Today they are mainly used for applied research and industrial applications. In view of this, the International Atomic Energy Agency (IAEA) has during recent years initiated several Coordinated Research Projects (CRPs) concerning Ion Beam Analysis of Materials, Accelerator Mass Spectrometry and Nuclear Microprobe Techniques. The CRPs involve laboratories from developing as well as developed Member States, networking on a common topic coordinated by the IAEA. In order to facilitate networking, the IAEA has recently published the "World Survey of Accelerator Based Analytical Techniques" available on the Internet and as a CD-ROM. The IAEA maintains also a beamline at a 6 MV Van de Graaff accelerator in the Ru đjer Bo\\vsković Institute, Zagreb, Croatia. Small and medium power accelerator driven spallation neutron sources will become more important as many small neutron producing research reactors are approaching the end of their useful working life. The IAEA has, within its Department for Nuclear Sciences and Applications, a programme on the Effective Utilization of Accelerators. This programme helps Member States, in particular developing Member States, in finding new areas of applications for their low and medium energy accelerators through increased participation in activities such as Coordinated Research Projects, Technical Meetings and Conferences. This paper describes the IAEA's current programme on accelerator utilization and proposed future activities.

    2016-01-01

    In this work, momentum imaging experiments have been conducted for the electron impact excitation of metastable states in noble gases and for dissociative electron attachment (DEA) in polyatomic molecules. For the electron impact excitation study a new experimental technique has been developed which is able to measure the scattering angle distribution of the electrons by detection of the momentum transfer to the atoms. Momentum transfer images have been recorded for helium and neon at fixed electron impact energy close to the excitation threshold and good agreement with current R-matrix theory calculations was found. A new momentum imaging apparatus for negative ions has been built for the purpose of studying DEA in biologically relevant molecules. During this work, DEA was investigated in the molecules ammonia, water, formic acid, furan, pyridine and in two chlorofluorocarbons. Furthermore, the change of DEA resonance energies when molecules form clusters compared to monomers was investigated in ammonia and formic acid. The experimental results of most studied molecules could be compared to recent theoretical calculations and they support further development in the theoretical description of DEA. The new apparatus built in this work also delivered a superior momentum resolution compared to existing setups. This allows the momentum imaging of heavier fragments and fragments with lower kinetic energy.

    This study, which focuses on the years 1968--1975, singles out important employment trends in the atomic energy field and develops causal explanations for these trends. The study also provides a descriptive profile of employment in the field. Employment in the atomic energy field has grown from 138,519 in 1963 to 197,466 in 1975, an annual rate of 3.0 percent. The deployment of scientists, engineers, and technicians in the government-owned, contractor-operated (GOCO) sector changed little from 1968 to 1975. Private sector deployment altered considerably, with a large increase. Within the scientist group, the GOCO sector employment by field has changed little from 1968 to 1975. Private sector scientists have seen considerable alteration of their employment. There has been little change in the employment shares of engineering fields in the GOCO sector for the 1968 to 1975 period. Private sector engineers have seen much greater change, with civil engineers increasing their share 6% to 11%. Of all GOCO technicians, physical science technicians have increased their employment share from 12% to 17%. Of all private sector technicians, draftsmen have increased their share from 29% to 37% and reactor operators from 4% to 7%. Total employment in the field is shifting toward smaller firms. Employment by region has changed considerably in the private sector from 1968 to 1975. GOCO regional employment has also changed. The percentage of scientists and engineers involved in research and development has declined from 68% in 1968 to 39% in 1975. Three private sector industrial segments--reactor design and manufacturing, nuclear facilities design and engineering, and operation and maintenance of reactors--have experienced tremendous growth from 1968 to 1975. 8 figures, 32 tables

    Titanium nitride and aluminum nitride coatings have been deposited on glass and aluminum oxide substrates in a flow of metal atoms accompanied by high-energy gas atoms. The metal atoms are produced due to sputtering of a flat rectangular magnetron target. The gas atoms with energy up to 25 keV are produced due to charge exchange collisions of ions extracted from the magnetron discharge plasma and accelerated by high-voltage pulses applied to a flat grid parallel to the target. The metal atoms pass through the grid and deposit on the substrate. Conjunction of their trajectories with those of gas atoms bombarding the growing coating enables the coating synthesis on complex-shape dielectric products planetary rotating inside the vacuum chamber. Mixing high-energy gas atoms of the coating and substrate atoms substantially improves the coating adhesion.

    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.

    In this talk I discuss the relevance of atomic physics in understanding some important questions about elementary particle physics. A particular attention is devoted to atomic parity violation measurements which seem to suggest new physics beyond the Standard Model. Atomic physics might also be relevant in discovering possible violations of the CPT symmetry.

    Major nuclear research institutes in Japan are the Japan Atomic Energy Research Institute (JAERI), Nuclear Cycle Development Institute (JNC), National Research Institute of Radiological Science (NIRS), and the Institute of Physical and Chemical Research (RIKEN). In the 50s and 60s JAERI concentrated on the introduction of nuclear technology from overseas. Energy security issues led to the development of a strong nuclear power programme in the next two decades resulting in Japan having 50 light water cooled nuclear power plants in operation. Japan also worked on other reactor concepts. The current emphasis of JAERI is on advanced reactors and nuclear fusion. Its budget of 270 million US$ supports five research establishments. JAERI has strong collaboration with industry and university system on nuclear and other advanced research topics (neutron science, photon science). In many areas Japan has strong international links. JAERI has also been transferring know-how on radioisotope and radiation applications to the developing countries particularly through IAEA-RCA mechanisms. (author)

    It the report, the legislation and policymaking systems, particularly for high-level radioactive wastes, in Japan and the U.S. are compared. Major legislation that reflects the policies for atomic energy in the U.S. includes: National Environmental Policy Act (1960, Nixon Administration), Low-Level Radioactive Waste Policy Act (1980, Carter Administration), Reagan's statement in October 1981, Nuclear Waste Policy Act (1982, Reagan Administration), 1986 Revision of Low-Level Radioactive Waste Policy Act, and 1987 Revision of Nuclear Waste Policy Act. According to the basic concept specified in the revised Nuclear Waste Policy Act, the Department of Energy is required to establish the 'Mission Plan'. The 1988 Mission Plan describes details of the wastes, MRS and repository as covered by the above-mentioned basic concept. The 1982 Nuclear Waste Policy Act and its 1987 revision focus procedures for policymaking concerning the treatment and disposal of wastes. In particular, the Act specifies the time sequence of the processes down to the waste disposal together with material-related processes including the material selection at the disposal site, and also clarifies the rights and obligations of the persons and organizations having the legal responsibility.

    Hamaoka Nuclear Power Station was constructed in the very large site of about 1.6 million m 2 surrounded by sand dunes and pine forests at the southern tip of Shizuoka Prefecture. Hamaoka Atomic Energy Hall was built on the right side of this power station. This hall had been planned as a part of the works commemorating the 20th anniversary of the founding of the company, and was opened in August, 1972. The building is of steel frame type, and has two floors of 1135 m 2 total area. The first floor comprises cinema room, power generation corner and open gallery, and the second floor comprises meeting room, native land corner and observation room. Moreover, there is observation platform on the roof. The purpose of the hall is coexistence and coprosperity with the regional residents, and 13 persons make explanations to visitors having reached to 1.9 million as of the end of June, 1979. It is incorporated in the sightseeing route centering around the Omaezaki lighthouse. The cinema hall accommodates 120 men, and the films concerning nuclear power generation and the construction of a nuclear power plant are shown. In the power generation corner, the explanation on nuclear power generation is made with models and panels. The third hall is being built now as energy corner, and it will be completed in autumn, 1979. (Kako, I.)

  20. Policy options when giving negative externalities market value: Clean energy policymaking and restructuring the Western Australian energy sector

    International Nuclear Information System (INIS)

    McHenry, Mark

    2009-01-01

    Uncertainty surrounds the choice of instruments that internalise fossil-fuel pollution at the local, regional and global level. This work outlines the considerable growth in the Western Australian (WA) energy sector and explores the available options and potential hazards of using specific instruments to internalise externalities. These core options are discussed with respect to liberalising energy markets, providing private investment certainty, and imparting commentary on the developments and consequences of reform in the WA context. As a large energy exporter, providing certainty for the WA energy sector investment and the community is necessary to maintain the current prosperity. Remarkably, in the decades of market reform progress, the absence of one essential element is evident: economic externalities. Policymakers are under increasing pressure to understand economic reform, new energy markets and the multifaceted repercussions they entail. With modern energy reform sitting squarely within the milieu of more efficient governments and climate policy, there are clear economic advantages to internalising negative and positive externalities and other market distortions during energy market developments. Ignoring market failures when commercialising government-owned energy utilities in de-regulated and competitive markets invites continued ad-hoc government interference that generates investment uncertainty in addition to a perplexed electorate

    Energy drinks are predominantly targeted to young adult consumers; however, there has been limited research into their effects on psychological functioning in this demographic group. This study examined cross-sectional associations between energy drink consumption and mental health in a population-based sample of young adults participating in the Western Australian Pregnancy Cohort (Raine) Study. We used self-report questionnaires to assess energy drink consumption and mental health (Depression Anxiety Stress Scale-21; DASS-21) at the 20-year cohort follow-up. In the regression analyses, we considered associations between energy drink consumption (mL/day) and continuous DASS-21 scores, adjusting for sociodemographic variables, alcohol and drug use, physical activity, body mass index (BMI), and dietary intake. Our sample included 502 males and 567 females (mean age 20 ± 3 years). After adjusting for potential confounding factors and controlling for coexisting mental health problems, energy drink consumption (per 100 mL/day) was significantly associated with anxiety (but not depression or stress), and this relationship was found only in males (β = 0.32; 95% CI = 0.05, 0.58). Our study found that energy drink consumption was associated with increased anxiety in young adult males. Further research into the possible contribution of energy drink use to the development of mental health problems in young adults is needed. © 2013 Wiley Periodicals, Inc.

  8. Atomic energy law after the opt-out. Alive and fascinating. Report about the 14th German atomic energy law symposium 2012

    International Nuclear Information System (INIS)

    Leidinger, Tobias

    2013-01-01

    Atomic energy law remains a living, fascinating subject matter. Nearly 200 participants were convinced of this impression at the 14 th German Atomic Energy Law Symposium held in Berlin on November 19-20, 2012. Under the scientific chairmanship of Professor Dr. Martin Burgi, Ludwig Maximilian University of Munich, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), after an interruption of 5 years, again organized a scientific conference about practice-related topics of atomic energy and radiation protection law. Atomic energy law once again proved to be a reference area for sophisticated issues of constitutional law and administrative law above and beyond its technical confines. The agenda of the 14 th German Atomic Energy Law Symposium featured a broad spectrum of topics ranging from backfitting of nuclear power plants to European atomic energy and radiation protection law, to challenges facing national legal systems in the execution of atomic energy law, to legal issues connected with decommissioning and waste management, and on to the topical subject of finding a repository site. The 14 th German Atomic Energy Law Symposium, on the whole, again demonstrated that an open discourse between science and practice is able to furnish important contributions to the implementation of laws in a balanced way rooted in practice. Especially the contributions dealing with the independence of public authorities and their organization, the doctrine of the reservation of functions of the executive branch, and planning by laws contain additional provisions able to influence the continued development of administrative law also above and beyond atomic energy law. The BMU also referred to a decision just heard from Brussels to the effect that a new European Safety Directive would be published as early as in 2013. As a consequence of the nuclear stress tests conducted EU-wide, the Directive is to lay down provisions about transparency

    1980-01-01

    A source of a metastable helium atom beam with a controlled energy based on a phenomenon of resonant ion neutralization on the surface of a solid body is described. The neutral particle energy control is carried out by changing ion velocities before their transformation into metastable atoms. The results of experiments with a modified construction of atomic beam source are stated. These experiments were conducted to find the possibilities to control velocities of atoms in a flow as well as to elucidate the peculiarities of operation of a collimator-converter of this construction. Dependences of a halfwidth of the ion velocity distribution function on the ion source parameters have been investigated. The possibility for particle energy control in a collimated flow of fast neutral. atoms has been experimentally shown, it is also shown that a mean value of atom energy in a beam coincides with a value of mean energy of ions from which atoms are produced by the resonant neutralization method; the construction of the source provides the possibility to realize the method of ''overtaking beams'' for neutral atoms and as a result of this to give a possibility for studying atom-atom collisions in a wide energy range at relatively high densities of flows

  11. The reorganisation of the French Atomic Energy Commission

    Glaize, G.

    1977-01-01

    The Atomic Energy Commission (CEA) has somewhat distinctive features when compared to other French public administrations. The Commission had been designed, when created in 1945, as a body very close to the Head of Government with, at the same time, great freedom of action; these two aspects demonstrated the importance accorded to its duties and the desire to assure its efficiency. The evolution of the Commission subsequently resulted in reducing these differences and strengthening the ministerial supervision as well as the role of the Administrator-General as compared with that of the High Commissioner. In the 1970s the Commission's structures developed in another direction, in view of the reorientation of its duties in the perspective of the development of the private nuclear sector and the increasing importance of nuclear safety questions. This reorganisation resulted in the creation of fairly autonomous operational units and a number of subsidiary bodies and specialised institutes. The outcome of this exercise has been to give the CEA a very diversified structure which is not as centralised as previously. (NEA) [fr

    Rainfall erosivity is the potential ability for rainfall to cause soil loss. The purpose of this study was to estimate the rainfall erosivity index for the Ghana Atomic Energy Commission site in order to compute the surface erosion rate. Monthly rainfall data, for the period 2003-2012 were used to compute annual rainfall erosivity indices for the site, using the Modified Fournier index. Values of the annual rainfall erosivity indices ranged from 73.5 mm for 2004 to 200.4 mm for the year 2003 with a mean annual erosivity index of 129.8 mm for the period. The Pearson's Coefficient of Correlation was used to establish the relationship between annual rainfall and annual rainfall erosivity. This showed a high degree of positive relationship (r = 0.7) for the study area. The computed mean annual erosivity index revealed that the site is in the high erosion risk zone. Therefore, it is necessary to develop soil protection and management strategies to protect the soil from erosion.

    1980-01-01

    The execution of the strategies of waste treatment and disposal calls for the laws and regulations on the obligations of the owners of equipments and facilities and of the state for securing safety and the final elimination of radioactive wastes, which are defined mainly in Article 9 of Atomgesetz and Section 2 (Article 44 - 48) of the order on protection from radiation. The owners of equipments and facilities of atomic energy technology shall limit the emission of radiation to about 6% of internationally permissible values, avoid uncontrolled emission without fail, inspect emission and submit reports yearly to government offices. The owners have attention obligations to utilize harmlessly produced radioactive residues and the expanded or dismantled parts of radioactive equipments or to eliminate orderly such things as radioactive wastes, only when such utilization is unable technically or economically, or not adequate under the protection aims of Atomgesetz. The possessors of radioactive wastes shall deliver the wastes to the accumulation places of provinces for intermediate storage, to the facilities of the Federal Republic for securing safety or final storage, or the facilities authorized by government offices for the elimination of radioactive wastes. Provinces shall install the accumulation places for the intermediate storage of radioactive wastes produced in their territories, and the Federal Republic shall set up the facilities for securing safety and the final elimination of radioactive wastes (Article 9, Atomgesetz).

  14. Optimal allocation of international atomic energy agency inspection resources

    International Nuclear Information System (INIS)

    Markin, J.T.

    1987-01-01

    Each year the Department of Safeguards of the International Atomic Energy Agency (IAEA) conducts inspections to confirm that nuclear materials and facilities are employed for peaceful purposes. Because of limited inspection resources, however, the IAEA cannot fully attain its safeguards goals either quantitatively as measured by the inspection effort negotiated in the facility attachments or qualitatively as measured by the IAEA criteria for evaluating attainment of safeguards goals. Under current IAEA procedures the allocation of inspection resources assigns essentially equal inspection effort to facilities of the same type. An alternative approach would incorporate consideration of all material categories and facilities to be assigned inspection resources when allocating effort to a particular facility. One such method for allocating inspection resources is based on the IAEA criteria. The criteria provide a framework for allocating inspection effort that includes a ranking of material types according to their safeguards importance, an implicit definition of inspection activities for each material and facility type, and criteria for judging the attainment of safeguards goals in terms of the quality and frequency of these inspection activities. This framework is applicable to resource allocation for an arbitrary group of facilities such as a state's fuel cycle, the facilities inspected by an operations division, or all of the facilities inspected by the IAEA

    2016-07-07

    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. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The energy and angular distributions of electrons ejected from targets and projectiles in the collisions of slow H and H{sup -} with He targets has been calculated exactly in a model that treats electron interactions with neutral targets via zero-range interactions. These calculations employ two-center Sturmian functions for collisions at non-zero impact parameters. The computed distributions are compared with recent measurements for He targets. Total ionization cross sections are also computed and compared with experiment over a broad energy range for proton, alpha particle and neutral hydrogen impact on helium atoms. The calculations are in generally good agreement with experiment.

    2011-01-01

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

    1994-01-01

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

  6. Challenges of atomic energy regulation in Indian context

    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

    Turkish Atomic Energy Authority (TAEA), established in 1982 by the Act no: 2690, is a governmental organization directly under the direct supervision of the Prime Minister. The objective of the establisment of TAEA is the peaceful utilization of atomic energy, regarding the national policy and the related plans and programs, for the benefits of State. The main duties of TAEA, as stated in related Act, can be summarized as: to determine and progress the basis of the national policy and the related plans and programs and to submit them to be approved by the Prime Minister; to execute and to support scientific, technical and administrative studies; to give approval, permission and license to the nuclear installations; to enlighten the public in nuclear matters; to establish research and educate the personnel in the nuclear field If Turkey would participate in a Nuclear Energy Program, especially, TAEA should perform its own duties properly and in this respect, as an Authority, we should have objectives that have to be determined as State Policy

    Since 1957, the International Atomic Energy Agency (IAEA) has worked to ensure the safe and responsible promotion of nuclear technology throughout the world. The IAEA operates at the intersection of the Nuclear Nonproliferation Treaty’s (NPT) fourth and third articles, which guarantee Parties to the Treaty the right to peaceful uses of nuclear technology, provided those activities are placed under safeguards verified by the IAEA. However, while the IAEA has enjoyed substantial success and prestige in the international community, there is a concern that its resources are being stretched to a point where it may no longer be possible to execute its multifaceted mission in its entirety. As noted by the Director General (DG) in 2008, demographics suggest that every aspect of the IAEA’s operations will be in higher demand due to increasing reliance on non-carbon-based energy and the concomitant nonproliferation, safety, and security risks that growth entails. In addition to these nuclear energy concerns, the demand for technical developmental assistance in the fields of food security, resource conservation, and human health is also predicted to increase as the rest of the world develops. Even with a 100% value-for-money rating by the U.S. Office of Management and Budget (OMB) and being described as an “extraordinary bargain” by the United Nations Secretary-General’s High-level Panel on Threats, Challenges and Change, real budget growth at the Agency has been limited to zero-real growth for a better part of the last two decades. Although the 2012 regular budget (RB) received a small increase for most programs, the 2013 RB has been set at zero-real growth. As a result, the IAEA has had to defer infrastructure investments, which has hindered its ability to provide the public goods its Members seek, decreased global security and development opportunities, and functionally transformed the IAEA into a charity, dependent on extrabudgetary (EB) contributions to sustain

    2011-01-01

    The Atomic Energy of Canada Limited (AECL) Waste Management Program establishes requirements for waste management activities at AECL sites in Canada. It ensures that activities involving planning for, handling, processing, transporting, storage and long-term management of wastes are performed in a manner that protects the workers, the public, and the environment, and are in compliance with applicable regulatory and licence requirements. The program translates applicable legal requirements into program requirements appropriate for AECL, and assists AECL management in implementing those requirements. The Waste Management Program was formally established at AECL in 2007 as one of the nuclear programs. The activities conducted in the first two years (2007 - 09) were mainly focused on program development. Currently the program is executing the waste management improvement initiatives based on the Waste Management Program Improvement Plan. During the program implementation, close collaboration between the Waste Management Program and other departments resulted in improved waste management performance at Chalk River Laboratories (CRL). This included increased segregation of the waste at the source, reduction in waste generation, improved labeling and identification of waste packages, improved recyclables collection and initiating recycling of selected hazardous wastes. In accordance with pollution prevention, the quantities and degree of hazard of wastes requiring long-term management shall be minimized, following the principles of Prevent, Reduce, Reuse, and Recycle. The annual volume of solid waste generated is one of the key indicators for waste management performance. AECL has been successful in reduction of operational waste and diversion of materials for recycling at CRL. From 2007 to 2010, the annual volume of solid waste, including inactive and radioactive wastes, generated from routine operations at CRL decreased by 26%, and the annual amount of recyclables sent

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

    International Nuclear Information System (INIS)

    CM Johnson

    2000-01-01

    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

    Highlights: ► A new solution for accurate prediction of surface free energy based on embedded atom method was proposed. ► The temperature dependent anisotropic surface energy of solid nickel was obtained. ► In isotropic environment, the approach does not change most predictions of bulk material properties. - Abstract: Accurate prediction of surface free energy of crystalline metals is a challenging task. The theory calculations based on embedded atom method potentials often underestimate surface free energy of metals. With an analytical charge density correction to the argument of the embedding energy of embedded atom method, an approach to improve the prediction for surface free energy is presented. This approach is applied to calculate the temperature dependent anisotropic surface energy of bulk nickel and surface energies of nickel nanoparticles, and the obtained results are in good agreement with available experimental data.

  14. Breit corrections to individual atomic and molecular orbital energies

    2018-01-01

    Several issues concerning Breit correction to electron-electron interaction in many-electron systems, which are important in precise atomic and molecular calculations, are presented. At first, perturbative versus self-consistent calculations of Breit correction were studied in selected cases. Second, the Z-dependence of Breit contribution per subshell is shown, based on values calculated for selected atoms with 30 ≤ Z ≤ 118. Third, the relations between magnetic and retardation parts of Breit interaction are analyzed. Finally, Gaunt contribution calculated for Kr, Xe, and Rn noble gas atoms and its iso-electronic HBr, HI, and HAt diatomic molecules has been compared to full-Breit atomic calculations. We found that Breit corrections should be treated by self-consistent calculations and that there is a functional dependence of those corrections for subshells as ɛnl B r e i t(Z ) ≃a ×Zb. We also found that molecular Gaunt corrections are close to their atomic counterparts for inner electrons though they are not for outer orbitals. In any case, accurate calculations must include retardation correction in addition to Gaunt.

    The emission of halogen and alkali atoms, occurring under bombardment of alkali halides with electrons has been investigated. The electron energy was 540 eV and the temperature of the target was varied between room temperature and 400 0 C. The energy distribution of the emitted neutral particles was measured with a time of flight method. It was found that either diffusing interstitial halogen atoms or moving holes dominate the sputtering process above 200 0 C. Below 150 0 C alkali halides with lattice parameters s/d >= 0.33 show emission of non-thermal halogen atoms. s is the interionic space between two halogen ions in a direction and d is the diameter of a halogen atom. In general the energy distribution of the alkali and halogen atoms is thermal above 200 0 C, but not Maxwellian. (Auth.)

    Japan Atomic Industrial Forum, Inc. summarized the results of 31st fact finding survey on atomic energy industries, which investigated and analyzed the actual status and future perspective of the expenditure, sales and personnel related to atomic energy in electric power, mining and manufacture and trading companies in FY1989. As to the state of activities of atomic energy industries, the expenditure related to atomic energy of electric power companies was 1633.7 billion yen, decrease by 7 % as compared with the previous fiscal year. The main factors are that the construction works of nuclear power stations came to temporary pause, and the operation and maintenance expenses for power stations turned to decrease due to the mechanization of inspection and the decrease of expendables. The sales related to atomic energy of mining and manufacturing companies was 1728.3 billion yen, which is the highest so far, and is increase by 18 % as compared with the previous fiscal year. Due to the diversification of atomic energy market, the manufacture for service field and others grew by 64 %, and the mechanization of production seemed to advance. The backlog of mining and manufacturing companies which is the index of future market trend was as high as 3526 billion yen. (K.I.)

  5. Life Cycle Greenhouse Gas Emissions from Electricity Generation: A Comparative Analysis of Australian Energy Sources

    Directory of Open Access Journals (Sweden)

    Robert G. Hynes

    2012-03-01

    Full Text Available Electricity generation is one of the major contributors to global greenhouse gas emissions. Transitioning the World’s energy economy to a lower carbon future will require significant investment in a variety of cleaner technologies, including renewables and nuclear power. In the short term, improving the efficiency of fossil fuel combustion in energy generation can provide an important contribution. Availability of life cycle GHG intensity data will allow decision-makers to move away from overly simplistic assertions about the relative merits of certain fuels, and focus on the complete picture, especially the critical roles of technology selection and application of best practice. This analysis compares the life-cycle greenhouse gas (GHG intensities per megawatt-hour (MWh of electricity produced for a range of Australian and other energy sources, including coal, conventional liquefied natural gas (LNG, coal seam gas LNG, nuclear and renewables, for the Australian export market. When Australian fossil fuels are exported to China, life cycle greenhouse gas emission intensity in electricity production depends to a significant degree on the technology used in combustion. LNG in general is less GHG intensive than black coal, but the gap is smaller for gas combusted in open cycle gas turbine plant (OCGT and for LNG derived from coal seam gas (CSG. On average, conventional LNG burned in a conventional OCGT plant is approximately 38% less GHG intensive over its life cycle than black coal burned in a sub-critical plant, per MWh of electricity produced. However, if OCGT LNG combustion is compared to the most efficient new ultra-supercritical coal power, the GHG intensity gap narrows considerably. Coal seam gas LNG is approximately 13–20% more GHG intensive across its life cycle, on a like-for like basis, than conventional LNG. Upstream fugitive emissions from CSG (assuming best practice gas extraction techniques do not materially alter the life cycle

    2006-01-01

    Full text: PRINCIPLE: A novel approach for nuclear metrology has been selected to study the effects of French Atomic Tests in the Pacific of 1974 on the Australian atmosphere. This is to investigate the changes in the elemental concentrations of the atmospheric particulates collected in Australia just before and after the onset of the atomic tests in the Pacific. Any additional radioactivity due to the tests would either be still there or would decay into stable isotopes. If by some very sensitive techniques one could determine the elemental / isotopic composition of the air particulate, one can work backwards in estimating the sort and quantity of activities that could have existed just after conducting of the tests. We decided to use the technique of charged-particle activation analysis to estimate the elemental / isotopic concentrations of the Australian Atmosphere. This technique has the potential to provide concentrations in the ppb and sub ppb regions. METHOD: The atmospheric particulates were collected on Polystyrene filters in high-volume air samplers placed all along the Australian East Coast at locations in Port Moresby (New Guinea), Townsville, Brisbane, Sydney, Melbourne and Hobart. The filters were cut into small pieces and placed in the grove of an Al-Target holder, covered by a thin Al-foil, which was cooled by liquid nitrogen. The samples were irradiated for one hour each with 8.5 MeV proton beam at an intensity of 1 μA. After waiting period of one hour the irradiated samples were counted with a high resolution and high sensitivity Germanium detector. Suitably prepared 'Standards', for quantifying the absolute concentrations, were also irradiated in identical fashion and their induced activities were measured. RESULTS AND DISCUSSION: A number of elements, like S, Ca, Ti, Cr, Fe, Ni, Cu, Zn, Se and Hg, were detected in the two types of samples- one taken just before the Atomic Tests started and the other set taken just after the finishing of the

    A single thumbnail variant of the food industry's voluntary front-of-package Daily Intake Guide (DIG)--called the 'Energy Alone' thumbnail (DIG kJ)--has recently appeared on many energy-dense, nutrient-poor foods and beverages, especially soft drinks and confectionery. However, there is no published data to date that has assessed its merit. A quota sample of 58 Australian adults (50% female; 47% blue collar; mean age 35 years, range 18-59) was presented with photographs of three food packages alternatively labelled with DIG kJ, full DIG (five thumbnails) and Traffic Lights (TL) systems. Participants ranked each labelling system along seven-point scales for the following dimensions: 'interpretable, 'noticeable', 'useful' 'and' a deterrent to purchasing unhealthy snack foods: Participants were afterwards brought together in eight focus groups of 7-8 to discuss the merits of each system. Paired samples t-tests suggested the DIG kJ was rated significantly less "noticeable" ,'useful'or'a deterrent'than either the full DIG or TL systems. The TL system was also rated as significantly more'interpretable"and"a deterrent'than either variant of DIG. In the focus groups, participants described the DIG kJ as too small to be noticeable, too abstract to be meaningful, and of little practical use. Higher energy on food labels was also associated with positive health, rather than as a risk for overconsumption. The DIG kJ performed poorly against the TL and full DIG. Our results suggest it is an ineffective food labelling system, that is unlikely to affect consumer knowledge, awareness, attitudes, purchasing or consumption behaviours.

    International Nuclear Information System (INIS)

    Watanabe, T.; Hino, K.

    1985-01-01

    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)

  4. Energy optimized Gaussian basis sets for the atoms T1 - Rn

    International Nuclear Information System (INIS)

    Faegri, K. Jr.

    1987-01-01

    Energy optimized Gaussian basis sets have been derived for the atoms Tl-Rn. Two sets are presented - a (20,16,10,6) set and a (22,17,13,8) set. The smallest sets yield atomic energies 107 to 123 mH above the numerical Hartree-Fock values, while the larger sets give energies 11 mH above the numerical results. Energy trends from the smaller sets indicate that reduced shielding by p-electrons may place a greater demand on the flexibility of d- and f-orbital description for the lighter elements of the series

    2012-01-01

    Computational method on energy distribution of primary knock-on atom (PKA) produced by neutron radiation was built in the paper. Based on the DBCN card in MCNP, reaction position, reaction type and energy transfer between neutrons and atoms were recorded. According to statistic of these data, energy and space distributions of PKAs were obtained. The method resolves preferably randomicity of random number and efficiency of random sampling computation. The results show small statistical fluctuation and well statistical. Three-dimensional figure of energy and space distribution of PKAs were obtained, which would be important to evaluate radiation capability of materials and study radiation damage by neutrons.

    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)

  8. 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.

    The production of two-meson electromagnetic bound states and free meson pairs π{sup +}π{sup -}, K{sup +}K{sup -}, π{sup +}K{sup -+} in relativistic collisions has been considered. It is shown that using of exact Coulomb wave functions for dimeson atom (DMA) allows one to calculate the yield of discrete states with the desired accuracy. The relative probabilities of production of DMA and meson pairs in the free state are estimated. The amplitude of DMA transition from 1S to 2P state, which is essential for the pionium Lamb shift measurements, has been obtained. (orig.)

    1995-01-01

    We estimate the vacuum polarization (VP) correction to the Coulomb interaction in collisions of muonic atoms. It is shown that the VP effect, amplified by the low-lying virtual state var-epsilon var-theta ∼10 eV, is of the order of ∼1--2 % in the S-wave cross sections for pμ+p collisions as var-epsilon ≤ var-epsilon var-theta . The VP amplitude becomes comparable to the anomalously small pure Coulomb amplitude for the singlet tμ+t scattering as var-epsilon →0 and near the Ramsauer-Townsend minima in the dμ+p and tμ+p scattering

    2006-01-01

    This study deals with the relationship between rapidly changing international security environments, the US security policy on the one hand, and policy environments of atomic energy. Based on the notion that the issue of atomic energy development is closely interrelated with the situation of international security especially after the tragic incident of 9/11, this study focuses on the impact of changing security environments on the conditions under which South Korea uses atomic power. It also deals with the subject of how the new framework of NPT, and the policy of IAEA influences upon South Korea's atomic polices in the future. This study examines the nature and contents of the US foreign policy and its efforts toward nonproliferation and counterproliferation. This study also deals with the Iranian case in which the US efforts of counterproliferation and Iranian argument for the rights of peaceful use of atomic energy based on the concept of national sovereignty. The Iranian case sheds light on the most acute aspect of current stage of nonproliferation, but also on the way of solving the North Korean nuclear crisis. This study also take issue with the future course of nonprolieration and the South Korea's policy for its maximum use of atomic energy

  17. Using Density Functional Theory (DFT) for the Calculation of Atomization Energies

    Science.gov (United States)

    Bauschlicher, Charles W., Jr.; Partridge, Harry; Langhoff, Stephen R. (Technical Monitor)

    1995-01-01

    The calculation of atomization energies using density functional theory (DFT), using the B3LYP hybrid functional, is reported. The sensitivity of the atomization energy to basis set is studied and compared with the coupled cluster singles and doubles approach with a perturbational estimate of the triples (CCSD(T)). Merging the B3LYP results with the G2(MP2) approach is also considered. It is found that replacing the geometry optimization and calculation of the zero-point energy by the analogous quantities computed using the B3LYP approach reduces the maximum error in the G2(MP2) approach. In addition to the 55 G2 atomization energies, some results for transition metal containing systems will also be presented.

  18. Precision Measurements of Atomic Lifetimes and Hyperfine Energies in Alkali Like Systems

    International Nuclear Information System (INIS)

    Tanner, Carol E.

    2005-01-01

    Financial support of this research project has lead to advances in the study of atomic structure through precision measurements of atomic lifetimes, energy splittings, and transitions energies. The interpretation of data from many areas of physics and chemistry requires an accurate understanding of atomic structure. For example, scientists in the fields of astrophysics, geophysics, and plasma fusion depend on transition strengths to determine the relative abundances of elements. Assessing the operation of discharges and atomic resonance line filters also depends on accurate knowledge of transition strengths. Often relative transition strengths are measured precisely, but accurate atomic lifetimes are needed to obtain absolute values. Precision measurements of atomic lifetimes and energy splittings also provide fundamentally important atomic structure information. Lifetimes of allowed transitions depend most strongly on the electronic wave function far from the nucleus. Alternatively, hyperfine splittings give important information about the electronic wave function in the vicinity of the nucleus as well as the structure of the nucleus. Our main focus throughout this project has been the structure of atomic cesium because of its connection to the study of atomic parity nonconservation (PNC). The interpretation of atomic PNC experiments in terms of weak interaction coupling constants requires accurate knowledge of the electronic wave function near the nucleus as well as far from the nucleus. It is possible to address some of these needs theoretically with sophisticated many-electron atomic structure calculations. However, this program has been able to address these needs experimentally with a precision that surpasses current theoretical accuracy. Our measurements also play the important role of providing a means for testing the accuracy of many-electron calculations and guiding further theoretical development, Atomic systems such as cesium, with a single electron

    Here we report the influence of key experimental parameters on atomically resolved energy dispersive X-ray spectroscopy (EDX). In particular, we examine the role of the probe forming convergence semi-angle, sample thickness, lattice spacing, and dwell/collection time. We show that an optimum specimen-dependent probe forming convergence angle exists to maximize the signal-to-noise ratio of the atomically resolved signal in EDX mapping. Furthermore, we highlight that it can be important to select an appropriate dwell time to efficiently process the X-ray signal. These practical considerations provide insight for experimental parameters in atomic resolution energy dispersive X-ray analysis. - Highlights: • Impacts of microscope operating conditions on EDX signal and atom column contrast are demonstrated. • Influence of sample thickness and lattice spacing is shown. • Conditions for obtaining optimal signal and contrast for different sample types are discussed. • Effects of dwell time during EDX acquisition are discussed.

  20. A study of beta decay energies and atomic masses

    International Nuclear Information System (INIS)

    Spanier, L.

    1988-04-01

    The q β energies of 123-131 In have been determined using the end points of β spectra recorded in β-γ coincidence experiments. A HPGe planar detector was used to detect the β-particles and a semi-empirical response function was used when unfolding the electron distribution. The mass excesses were deduced and when they were compared with the predictions of various mass formulae, the cadmium isotopes were found to be heavier than those predicted by most of the mass formulae. The excitation energy of the 1/2 - proton-hole state in the odd indium isotopes was shown to be constant for all the heavy isotopes. The Q EC energies of 148 Dy and 96 Pd were determined using the β + /EC intensity ratio method. The ratio of the intensity of the β+ branch to the total beta decay intensity was determined by means of γ-spectroscopic methods. The mass excesses were deduced. The two-proton binding energy for the N=82 isotones showed only a small step of approximately 0.5 MeV when the doubly-magic nucleus 146 Gd was encountered. A liquid drop type mass formula with deformation and shell energy corrections and with few free parameters is presented. The shell energy correction is a simple analytical expression for the equilibrium deformation of the nucleus. An analytical expression for the equilibrium nuclear deformation is also presented. The mass formula was applied to nuclei with Z and N greater than 50. The RMS deviation is 0.55 milli mass units. The reaction 98 Mo(p,n) 98 Tc was investigated through the counter ratio method, the ratio of the number of slow neutrons to the number of fast neutrons. The Q pn energy value of a low-spin state in 98 Tc was determined. The state at 90.9 keV excitation energy is proposed to be the 14.6 m u s isomer and have spin and parity 1 + . (author)

  1. Burning issue of energy problem after Fukushima disaster of TEPCO's atomic power stations

    International Nuclear Information System (INIS)

    Harada, Shoji

    2012-01-01

    Strikes of unanticipated enormous earthquake and subsequent tsunami brought unbelievable disaster in eastern Japan on March 11, 2012. In particular, collapse of cooling system of TEPCO's Fukushima atomic power stations resulted in IAEA-defined level7 accident including heavy radiation, hydrogen explosion -induced collapse of the building of power station No.2 and No.4 and melt through of nuclear pressure vessel No1.3.4 At an initial stage of the disaster, nobody knew precisely what happened at the power stations. According to the recent report of the national investigation committee, precise reason of the collapse of the cooling system whether it was induced by the strike of huge earthquake or tsunami is still unclear. Due to poor risk management of the government and TEPCO and closure of the precise disaster information, people became suspicious and nervous about the atomic power station. Fifty four atomic power stations have been constructed for these forty years in Japan. On last May 04, all the atomic power stations were shut down due to periodic inspection. However, restart of them became hot discussion. Although atomic power station was regarded as a powerful tool to reduce carbon dioxide several years ago, this situation after March 11 completely changed. In many countries which possess atomic power station, making a road map to develop recyclable energy is a burning issue. It should be noted that German spent about thirty years to declare atomic energy free society. Finally necessity of succession of technology of utilizing atomic power is emphasized. Politics on depending atomic power differs in each country. Therefore, study from Fukushima disaster should be widely used to prevent from unexpected accident of atomic power station.

    Antihydrogen is currently the subject of great interest as cold H has recently been prepared at CERN by the ATHENA and ATRAP projects. This work is described elsewhere in this volume. In this paper, we describe a calculation that we have carried out recently for very low-energy HH scattering using the Kohn variational method and including three rearrangement channels in addition to the elastic channel. We also consider the He-H system and give a progress report on the calculation that we are currently carrying out for this system.

    1987-01-01

    Legal and political studies on the activities of the IAEA infer that the pacific uses of nuclear energy become more significant every day in the ambit of international relationships. The studies analyze as a whole relationships among member states. The first part is divided into four chapters, starting with the background and creation of the agency, its structure, statutes, amendments and the performance of its main organisms. It continues to describe mechanisms and programmes carried out, including cooperation agreements between the IAEA and other specialized organizations in the United Nations. It ends up with the IAEA performance resulting from different treaties. The second part examines Mexican norms on nuclear matter as well as relationships between Mexico and the IAEA. It demonstrates that achievements in the Agency have been possible because of the establishment of an international cooperation basis, which avoids duplicity of actions. The conclusions recommend joint efforts from both the developed and the developing countries in the following: a) to imbue public opinion with the goodness of nuclear energy; b) to discourage the construction and operation of nuclear installations; c) to unify national standards on nuclear safety and control; d) to decrease export restrictions, based on safeguards; e) to promote internal nuclear research in Mexico or throught regional integration agreements, with technical assistance and support from the IAEA.

  20. Low energy ionization effect of He atoms at surfaces

    Muda, Y.; Newns, D. M.

    1988-06-01

    The low energy ionization effect, which seems so surprising on the basis of the Massey criterion, has been explained by a dynamical calculation working with a diabatic 1s level of He whose behaviour is determined from the projectile-target correlation diagram. Quasi-realistic hopping matrix elements and the He trajectory based on a Molière potential are employed. Using a spinless time dependent Newns-Anderson Hamiltonian, the ionization probability Pion has been calculated exactly within the present model by the method of Muda and Hanawa. It is found that Pion amounts to a significant value even at low incident energies ( E0) below 1 keV in He → Si collision, where the Si substrate is represented by a linear chain (LC) of 30 Si 3s orbitals. In He → Cu collision, where the Cu substrate is approximated by a LC of 30 Cu 4s orbitals, Pion is very small for E0 below 1 keV, but it is appreciable above 1 keV. The ratio of Pion( Cu)/ Pion(Si) in the region 1 ≦ E0 ≦ 2 keV is in good agreement with that derived from a recent experiment.

    This paper describes the achievements of a program in which technology education is provided to cultivate practical core engineers for low-level radiation. It was made possible by means of (1) an introductory education program starting at an early age and a continuous agenda throughout college days and (2) regional collaboration. First, with regard to the early-age introductory education program and the continuous education agenda, the subjects of study related to atomic energy or nuclear engineering were reorganized as “Subjects related to Atomic Power Education” for all grades in all departments. These subjects were included in the syllabus and the student guide book, emphasizing a continuous and consistent policy throughout seven-year college study, including the five-year system and additional two-year advanced course. Second, to promote practical education, the contents of lectures, experiments, and internships were enriched and realigned in collaboration with the Japan Atomic Energy Agency, Okayama University and The Cyugoku Electric Power Co., Inc. In addition to the expansion and rearrangement of atomic power education, research on atomic power conducted for graduation thesis projects were undertaken to enhance the educational and research activities. In consequence, it has been estimated that there is now a total of fourteen subject areas in atomic energy technology, more than eight-hundred registered students in the department, and thirteen members of the teaching staff related to atomic energy technology. Furthermore, the “Tsuyama model” is still being developed. This program was funded by the Ministry of Education, Culture, Sports, Science and Technology.

    The cross section for double-electron ionization of two-electron atoms and ions in Compton scattering of high energy photons is calculated. It is demonstrated that its dependence on the incoming photon frequency is the same as that for single-electron ionization. The ratio of open-quotes double-to-singleclose quotes ionization in Compton scattering was found to be energy independent and almost identical with the corresponding value for photoionization. For the He atom it is 1.68%. This surprising result deserves experimental verification

    This study describes the achievements of a program that provides technology education about radiation to develop practical core engineers, then the effects of the programed were discussed. An education program starting at an early age and continuous and consistent educational agendas through seven years of college has been constructed in collaboration with regional organizations. Subjects relating to atomic energy or nuclear engineering were regrouped as “Subjects Related to Atomic Power Education” for most grades in each department. These subjects were included in the syllabus and the student guide book to emphasize a continuous and consistent policy throughout the seven-year period of college study, comprising the five-year system and the additional two-year advanced course. Furthermore, the content of lectures, experiments, and internships was enriched and realigned in collaboration with the Japan Atomic Energy Agency (JAEA), Okayama University, and Chugoku Electric Power Co., Inc. Additional educational materials were developed from inspection visits by teaching staff to atomic energy facilities were also used in the classes. Two student experiment textbooks were developed to promote two of the subjects related to atomic energy: “Cloud Chamber Experiment” and “A Test of γ-ray Inverse Square Law.” In addition to the expansion and rearrangement of atomic power education, research on atomic power conducted for graduation thesis projects was undertaken to enhance educational and research activities. Some examples are as follows: “Study on the Relation between γ Dose Rate and Rainfall in Northern Okayama Area,” “Remote Sensing of Radiation Dose Rate by Customizing an Autonomous Robot,” and “Nuclear Reaction Analysis for Composition Measurement of BN Thin Films.” It should be noted that an atomic-energy-related education working group has been in place officially to continue the above activities in the college since 2011.

    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)

  15. Classical calculation of the total ionization energy of helium-like atoms

    International Nuclear Information System (INIS)

    Karastoyanov, A.

    1990-01-01

    Quantum mechanics rejects the classical modelling of microworld. One of the reasons is that the Bohr's rules can not be applied for many-electron atoms and molecules. But the many-body problem in classical mechanics has no analytical solution even for 3 particles. Numerical solutions should be used. The quantum Bohr's rule expressing the moment of momentum conservation for two particles is invalid in more complicated cases. Yet Bohr reached some success for helium-like atoms. The Bohr's formula concerning helim-like atoms is deduced again in this paper and its practical reliability is analyzed with contemporary data. The binding energy of the system is obtained in the simple form E=(Z-1/4) 2 α 2 mc 2 , where Z is the atomic number, α - the fine structure constant, M - the electron mass and c - the light speed in vacuum. The calculated values are compared with experimental data on the total ionization energy of the helium-like atoms from 2 He 4 to 29 Cu 64 . The error decreases quickly with the increasing of atomic mass, reaching zero for Cu. This indicated that the main source of error is the nucleus motion. The role of other possible causes is analyzed and proves negligible. (author). 1 tab, 4 refs

    Cross, J.B.; Blais, N.C.

    1988-01-01

    A high intensity (10 19 O-atoms/s-sr) high energy (5 eV) source of oxygen atoms has been developed that produces a total fluence of 10 22 O-atoms/cm 2 in less than 100 hours of continuous operation at a distance of 15 cm from the source. The source employs a CW CO 2 laser sustained discharge to form a high temperature (15,000 K) plasma in the throat of a 0.3-mm diameter nozzle using 3--8 atmospheres of rare gas/O 2 mixtures. Visible and infrared photon flux levels of 1 watt/cm 2 have been measured 15 cm downstream of the source while vacuum UV (VUV) fluxes are comparable to that measured in low earth orbit. The reactions of atomic oxygen with kapton, Teflon, silver, and various coatings have been studied. The oxidation of kapton (reaction efficiency = 3 /times/ 10/sup /minus/24/ cm /+-/ 50%) has an activation energy of 0.8 Kcal/mole over the temperature range of 25/degree/C to 100/degree/C at a beam energy of 1.5 eV and produces low molecular weight gas phase reaction products (H 2 O, NO, CO 2 ). Teflon reacts with ∼0.1--0.2 efficiency to that of kapton at 25/degree/C and both surfaces show a rug-like texture after exposure to the O-atom beam. Angular scattering distribution measurements of O-atoms show a near cosine distribution from reactive surfaces indicating complete accommodation of the translational energy with the surface while a nonreactive surface (nickel oxide) shows specular-like scattering with 50% accommodation of the translational energy with the surface. A technique for simple on orbit chemical experiments using resistance measurements of coated silver strips is described. 9 figs

  19. Identifying the Minimum-Energy Atomic Configuration on a Lattice: Lamarckian Twist on Darwinian Evolution

    Energy Technology Data Exchange (ETDEWEB)

    d' Avezac, M.; Zunger, A.

    2008-01-01

    We examine how the two different mechanisms proposed historically for biological evolution compare for the determination of crystal structures from random initial lattice configurations. The Darwinian theory of evolution contends that the genetic makeup inherited at birth is the one passed on during mating to new offspring, in which case evolution is a product of environmental pressure and chance. In addition to this mechanism, Lamarck surmised that individuals can also pass on traits acquired during their lifetime. Here we show that the minimum-energy configurations of a binary A{sub 1-x}B{sub x} alloy in the full 0 {le} x {le} 1 concentration range can be found much faster if the conventional Darwinian genetic progression--mating configurations and letting the lowest-energy (fittest) offspring survive--is allowed to experience Lamarckian-style fitness improvements during its lifetime. Such improvements consist of A {leftrightarrow} B transmutations of some atomic sites (not just atomic relaxations) guided by 'virtual-atom' energy gradients. This hybrid evolution is shown to provide an efficient solution to a generalized Ising Hamiltonian, illustrated here by finding the ground states of face-centered-cubic Au{sub 1-x}Pd{sub x} using a cluster-expansion functional fitted to first-principles total energies. The statistical rate of success of the search strategies and their practical applicability are rigorously documented in terms of average number of evaluations required to find the solution out of 400 independent evolutionary runs with different random seeds. We show that all exact ground states of a 12-atom supercell (2{sup 12} configurations) can be found within 330 total-energy evaluations, whereas a 36-atom supercell (2{sup 36} configurations) requires on average 39,000 evaluations. Thus, this problem cannot be currently addressed with confidence using costly energy functionals [e.g., density-functional theory (DFT) based] unless it is limited to

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

    Science.gov (United States)

    Senda, Yasuhiro; Blomqvist, Janne; Nieminen, Risto M

    2016-09-21

    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.

  2. The first atomic power station and international co-operation in the peaceful uses of atomic energy

    1974-01-01

    The commissioning of the first nuclear power station in the Soviet Union could not but affect the development of nuclear power in the rest of the world, a form of power which in the coming decades will determine the energy balance of our planet. The first atomic power station became a scientific laboratory, a treasure house of experience and a forge for training personnel. Since it went into operation it has been visited by more than 2000 delegations, 60 000 persons in all, including eminent scientists like Homi Bhabha, John Bernal, Sigvard Eklund, Glenn Seaborg, Gustav Herz, Francis Perrin and many others. They all recognized the great significance of the first atomic power station. Jawaharlal Nehru wrote in the visitors' book that he had been glad to visit the station and was fascinated by it; it helped one, he said, to visualize the future which was already unfolding. The first atomic power station symbolized the triumph of the human intellect, the inexhaustibility of scientific progress and the unflinching aspirations of the peoples of the world for peace. These aspirations, together with the efforts of men of good will and expanding international collaboration, contributed in large measure to the signing of the Moscow Test Ban Treaty in 1963, the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies in 1967, the Treaty on the Non-Proliferation of Nuclear Weapons in 1968, the Treaty on the Prohibition of the Emplacement of Nuclear Weapons and Other Weapons of Mass Destruction on the Sea-Bed and Ocean Floor and in the Subsoil thereof and, quite recently (1973), the agreement between the Soviet Union and the United States of America on averting the threat of nuclear war

  3. Energy Levels and Spectral Lines of Li Atoms in White Dwarf Strength Magnetic Fields

    Zhao, L. B.

    2018-04-01

    A theoretical approach based on B-splines has been developed to calculate atomic structures and discrete spectra of Li atoms in a strong magnetic field typical of magnetic white dwarf stars. Energy levels are presented for 20 electronic states with the symmetries 20+, 20‑, 2(‑1)+, 2(‑1)‑, and 2(‑2)+. The magnetic field strengths involved range from 0 to 2350 MG. The wavelengths and oscillator strengths for the electric dipole transitions relevant to these magnetized atomic states are reported. The current results are compared to the limited theoretical data in the literature. A good agreement has been found for the lower energy levels, but a significant discrepancy is clearly visible for the higher energy levels. The existing discrepancies of the wavelengths and oscillator strengths are also discussed. Our investigation shows that the spectrum data of magnetized Li atoms previously published are obviously far from meeting requirements of analyzing discrete atomic spectra of magnetic white dwarfs with lithium atmospheres.

    We consider the resonance interaction energy between two identical entangled atoms, where one is in the excited state and the other in the ground state. They interact with the quantum electromagnetic field in the vacuum state and are placed in a photonic-bandgap environment with a dispersion relation quadratic near the gap edge and linear for low frequencies, while the atomic transition frequency is assumed to be inside the photonic gap and near its lower edge. This problem is strictly related to the coherent resonant energy transfer between atoms in external environments. The analysis involves both an isotropic three-dimensional model and the one-dimensional case. The resonance interaction asymptotically decays faster with distance compared to the free-space case, specifically as 1/r 2 compared to the 1/r free-space dependence in the three-dimensional case, and as 1/r compared to the oscillatory dependence in free space for the one-dimensional case. Nonetheless, the interaction energy remains significant and much stronger than dispersion interactions between atoms. On the other hand, spontaneous emission is strongly suppressed by the environment and the correlated state is thus preserved by the spontaneous-decay decoherence effects. We conclude that our configuration is suitable for observing the elusive quantum resonance interaction between entangled atoms.

  10. Current trends in court rulings on matters of the Atomic Energy Law

    International Nuclear Information System (INIS)

    Degenhart, C.

    1989-01-01

    Today's Atomic energy law is at a high development level and offers increased legal safety at a point of time when the extension of nuclear energy has been largely concluded in the FRG. The procedural constellation of third-party objections in characteristic of the development of the atomic energy law. Principal objections to the peaceful use of nuclear energy have been largely disproved by court rulings. Residual risks of this technology are to be accepted as 'socially adequate basic burdens'. 'Abandonment' of nuclear energy is not precluded by the structure of Atomic Energy Law Standards but is mainly a political question to be answered by the executive. In future, legal issues of nuclear waste disposal, fuel cycle and assessment of new plant types will dominate the discussion. Verification and certification of waste disposal should not be demanded in the stage of plant approval, however, should safe disposal prove to be infeasible, nuclear energy use may well have to be re-assessed legally.

    Miyazaki, T.; Fueki, K.

    1980-01-01

    Selective hydrogen - atom - abstraction reaction by H or D atom has been studied in a neo C 5 H 12 - C 2 H 6 (less than 1 mol %) mixture at 77 K by ESR spectroscopy. The H (or D) atom produced by the photolysis of HI (or DI) reacts with neo - C 2 H 12 and C 2 H 6 to form neo - C 5 H 11 and C 2 H 5 radicals. In order to obtain H atoms with different kinetic energies, the photolysis was performed with different lights of 313, 254 and 229 nm. The selective formation of the C 2 H 5 radical by the reaction of the H (or D) atom with C 2 H 6 becomes more effective with the decrease in the energy of the H (or D) atom. The formation of the neo - C 5 H 11 radical by the reaction of the H (or D) atom with neo - C 2 H 12 becomes more effective with the increase in the energy of the H (or D) atom. (A.R.H.) [pt

  18. Specific features of energy and spatial distribution of primary knocked-out atoms in monocrystals

    International Nuclear Information System (INIS)

    Taratin, A.M.; Vorob'ev, S.A.

    1978-01-01

    By simulation trajectories of 0.2 MeV protons in 1 μm thick Al monocrystal, the energy and spatial distributions of primary atoms knocked out by the protons (PKA) have been studied. Different orientations of the incident beam axis relative to the densely packed direction in the case of ''quasichanneling'' and ''chaotic'' scattering of particles by the crystal have been researched. The depth dependence of the number of generated PKA, their distribution in the plane transverse to the preferred direction, and the energy spectrum of PKA have been obtained. It is shown that the PKA volume density is higher than that obtained using evaluations not accounting for the crystalline structure, and the energy spectrum contains more low energy PKAs. A concept of the cross section of the PKA production on an atomic chain is introduced for ipterpretation of the data obtained

    1991-05-01

    To quantitatively study electron capture during collisions of multiply charged ions with neutral atoms at near-thermal energies, keV-energy multicharged ion beams are merged with ground-state beams of H or D atoms of chosen velocity such that collisions in the relative energy range 1-1000 eV/amu result. Recent data for O 3+, O 4+ +H(D) are presented and compared with theoretical predictions. Recently completed modifications to the apparatus are described that will provide a significant improvement in signal-to-background and angular collection. These improvements will allow measurements to be extended to lower energies, where effects due to the ion-induced dipole attraction may be evident.

  19. Adult education about atomic energy, 1945-1948, as a case study in science for society

    1984-01-01

    The sudden existence of atomic energy presented five challenges to science education for the adult public: (1) inform adults that atomic energy existed; (2) teach them its scientific basis, and potential peacetime uses; (3) correct mistaken impressions from erroneous media coverage; (4) promote civic literacy and participation in decision making; and (5) inform voters about pending atomic energy legislation. Newspapers, magazines, radio, and newsreels were the major sources of informal adult education, together reaching 93% of adults. But these informational media lacked educational structure, and failed to meet the citizenship needs of adults. During that pre-television era, discussion groups were a common form of social gathering and nonformal education. Books and pamphlets for these groups were essential to a system of adult science education. They provided data for the open exchange of opinions that is essential to the process of adult education. The League of Women Voters of the United States established a network of discussion groups nationwide, providing printed materials for all five purposes. These programs enjoyed mixed success, providing at least local pockets of public enlightenment. By 1948, the Atomic Energy Commission was facilitating public education, especially in private industry and the business sector

    In view of the present lack of agreement on nuclear energy utilization the lecturer would rather abide by the present legal status of the Atomic Energy Act and thus prefer no amendment. However he considers a jurisprudential discussion expedient and debates the main points of the Rengeling expertise from his point of view: privatization, licensing competence, plan approval, proof of having made provisions for waste disposal, European cooperation, direct ultimate waste disposal, financing.

    Eisberg and Resnick present a simple argument for the energy of an electron in a multielectron atom using the concept of shielding from electrons in inner shells. The results of such a treatment are unfortunately confined so as to be out of range of experimental values. Here, the effect of electrons in outer shells is included, and, in the nonrelativistic region, energies are obtained for electrons in the first and second shells in reasonable agreement with experiment.

    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.

  3. Safety philiosophies in technology-related law discussed for the example of atomic energy law

    In practice, legal ruling and its technical implementation stand isolated side by side. Taking the example of atomic energy law, the reasons for this situation and the significance of the deficit in the legal control of technology are examined. It is discussed how the controlling capacity of the law can be increased through the legal implementation of safety philosophies for technology. The paper deals with the problematic realtionship between technical and legal norms, with safety philosophies in the sense of mental approaches, safety concepts or safety postulates and their legal significance, and with the safety philosophy adhered to by the authorities and courts. The following learning processes in safety philosophy are described: new concepts of protection within the field of determinism, probabilistic safety concepts as well as concepts for the reduction of damage potential. Altogether it can be stated that the safety philosophy currently adhered to in Federal German licensing practice is not the only possible one; rather, that there are many different ways of conceptualizing, stipulating and checking technical safety. At least in the field of atomic energy law, this insight has a twofold significance: de lege lata there are several ways of operationalizing the licence requirements laid down in Article 7 of the Atomic Energy Law and the legally defined requirements for a licence withdrawal with the aid of technical licensing criteria. In all cases the legal wording is indeterminate and does not prescribe any specific safety philosophy. De lege ferenda it must be noted that amendments to the Atomic Energy Law entail a regularization of safety philosophy. This is a political necessity if the Atomic Energy Law is to be developed further and thus maintained as a modern security law. (orig.) [de

  4. Discrete Energies of a Weakly Outcoupled Atom Laser Beam Outside the Bose–Einstein Condensate Region

    2014-12-01

    Full Text Available We consider the possibility of a discrete set of energies of a weakly outcoupled atom laser beam to the homogeneous Schrödinger equation with anisotropic harmonic trap in Cartesian coordinates outside the Bose–Einstein condensate region. This treatment is used because working in the cylindrical coordinates is not really possible, even though we implement the cigar-shaped trap case. The Schrödinger equation appears to replace a set of two-coupled Gross– Pitaevskii equations by enabling the weak-coupling assumption. This atom laser can be produced in a simple way that only involves extracting the atoms in a condensate from by using the radio frequency field. We initially present the relation between condensates as sources and atom laser as an output by exploring the previous work of Riou et al. in the case of theoretical work for the propagation of atom laser beams. We also show that even though the discrete energies are obtained by means of an approaching harmonic oscillator, degeneracy is only available in two states because of the anisotropic external potential

    One elaborated nonperturbation theory of energy losses at collisions of structural highly-charged heavy ions moving with relativistic speed. Ions containing partially populated electron shells are taken to be structural ions. The elaborated theory considers ion as an extended structural particle which size is equal to that of electronic shells. Paper contains the results of calculations of the efficient breaking at collision of a relativistic highly-charged ions with hydrogen atom derived for three domains of collision parameter values corresponding to low, average and high parameters of collision. The derived results are generalized for the case of collisions of relativistic structural heavy ions with compound atoms [ru

    We propose a machine-learning method for evaluating the potential barrier governing atomic transport based on the preferential selection of dominant points for atomic transport. The proposed method generates numerous random samples of the entire potential energy surface (PES) from a probabilistic Gaussian process model of the PES, which enables defining the likelihood of the dominant points. The robustness and efficiency of the method are demonstrated on a dozen model cases for proton diffusion in oxides, in comparison with a conventional nudge elastic band method.

  8. On the merger between Toshiba Corporation and Japan Atomic Energy Operation Co., Ltd. (reply report)

    The Nuclear Safety Commission made a careful examination regarding the merger between Toshiba Corporation and Japan Atomic Energy Operation Co., Ltd., (an issue submitted on August 16, 1989, for deliberation), and submitted a report to the prime minister. A study was carried out to determine whether the technical expertise possessed by Japan Atomic Energy Operation Co. would taken over properly by Toshiba Corporation, which would continue to exist after the merger. Results of the study revealed that the organization and technical experts existing at Japan Atomic Energy Operation Co. before the merger would properly incorporated into the existing system in Toshiba Corporation. Thus, it was confirmed that Toshiba Corporation after the merger would have technical capabilities required to install and operate nuclear reactors. The Atomic Nuclear Safety Commission started the above-mentioned study on the subject matter at the 32nd meeting, which was held on August 24, 1989, and reached the conclusion at the 34th meeting held on August 31, 1989.

    Effective atomic numbers, electron densities of some vitamins (Retinol, Riboflavin, Niacin, Biotin, Folic acid, Cobalamin, Phylloquinone and Flavonoids) composed of C, H, O, N, Co, P and S have been calculated for total and partial photon interactions by the direct method for energy range 1 keV-100 GeV by using WinXCOM and kinetic energy released in matter (Kerma) relative to air is calculated in energy range of 1 keV-20 MeV. Change in effective atomic number and electron density with energy is calculated for all photon interactions. Variation of photon mass attenuation coefficients with energy are shown graphically only for total photon interaction. It is observed that change in mass attenuation coefficient with composition of different chemicals is very large below 100 keV and moderate between 100 keV and 10 MeV and negligible above 10 MeV. Behaviour of vitamins is almost indistinguishable except biotin and cobalamin because of large range of atomic numbers from 1(H) to 16 (S) and 1(H) to 27(Co) respectively. K a value shows a peak due to the photoelectric effect around K-absorption edge of high- Z constituent of compound for biotin and cobalamin.

    In an address to the 8th General Assembly of the United Nations (1953) the President of the United States suggested that Governments should begin to make joint contributions from their stockpiles of fissile materials to an international atomic energy agency which would be set up under the aegis of the United Nations. The fissile material so collected would be used to serve the peaceful pursuits of mankind. Experts would be mobilized to apply atomic energy to the needs of agriculture, medicine and other peaceful purposes and a special effort would be made to provide abundant electrical energy in the power-starved areas of the world. This suggestion was taken up. A Statute which defines the structure and purpose of the International Atomic Energy Agency (IAEA) was prepared by a group of nations and approved by a conference at the United Nations Headquarters in 1956. The Statute entered into force on 29 July 1957. The Agency's objectives, as defined in its Statute, are that it ''shall seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world. It shall ensure, as far as it is able, that assistance provided by it or at its request or under its supervision or control is not used in such a way as to further any military purpose''. To attain these objectives, the IAEA is authorized ''to encourage and assist research on, and development and practical application of, atomic energy for peaceful uses throughout the world; and, if requested to do so, to act as an intermediary for the purposes of securing the performance of services or the supplying of materials, equipment, or facilities by one member of the Agency for another''; to ''... assemble and make available in an accessible form the [scientific] information made available to it...'' and furthermore ''to make provision, ... for materials, services, equipment, and facilities to meet the

    Energy levels and oscillator strengths were calculated for 3s-3p and 3p-3d transition arrays in Fe XV, isoelectronic to Mg I. The energy levels are obtained by the Slater-Condon theory of atomic structure, including explicitly the strong configuration interactions. The calculated wavelengths are presented for electric dipole transition with gf>= 0.0001. The calculated energy levels are given in diagrams, too. The theoretical spectra are also shown in graphical representation, where the gf is plotted as a function of the wavelength. The results are compared with experimental data, where available.

    We propose a two-energy twin image removal algorithm for atomic-resolution x-ray holography. The validity of the algorithm is shown in a theoretical simulation and in an experiment of internal detector x-ray holography using a ZnSe single crystal. The algorithm, compared to the widely used multiple-energy algorithm, allows efficient measurement of holograms, and is especially important when the available x-ray energies are fixed. It enables twin image free holography using characteristic x rays from laboratory generators and x-ray pulses of free-electron lasers

    The atomic solid state energy (SSE) scale originates from a plot of the electron affinity (EA) and ionization potential (IP) versus band gap (E{sub G}). SSE is estimated for a given atom by assessing an average EA (for a cation) or an average IP (for an anion) for binary inorganic compounds having that specific atom as a constituent. Physically, SSE is an experimentally-derived average frontier orbital energy referenced to the vacuum level. In its original formulation, 69 binary closed-shell inorganic semiconductors and insulators were employed as a database, providing SSE estimates for 40 elements. In this contribution, EA and IP versus E{sub G} are plotted for an additional 92 compounds, thus yielding SSE estimates for a total of 64 elements from the s-, p-, d-, and f-blocks of the periodic table. Additionally, SSE is refined to account for its dependence on oxidation state. Although most cations within the SSE database are found to occur in a single oxidation state, data are available for nine d-block transition metals and one p-block main group metal in more than one oxidation state. SSE is deeper in energy for a higher cation oxidation state. Two p-block main group non-metals within the SSE database are found to exist in both positive and negative oxidation states so that they can function as a cation or anion. SSEs for most cations are positioned above −4.5 eV with respect to the vacuum level, and SSEs for all anions are positioned below. Hence, the energy −4.5 eV, equal to the hydrogen donor/acceptor ionization energy ε(+/−) or equivalently the standard hydrogen electrode energy, is considered to be an absolute energy reference for chemical bonding in the solid state. - Highlights: • Atomic solid-state energies are estimated for 64 elements from experimental data. • The relationship between atomic SSEs and oxidation state is assessed. • Cations are positioned above and absolute energy of −4.5 eV and anions below.

    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.

  15. Z-1 perturbation theory applied to the correlation energy problem of atoms

    International Nuclear Information System (INIS)

    Robinson, B.H.

    1975-01-01

    Rayleigh--Schroedinger Perturbation Theory is applied to obtain directly exact and explicit analytic formulas for the electron correlation energies of N electron systems in terms of their pairwise interactions through second order in Z -1 , where Z is the nucleus of the atom. It is demonstrated that the second order correlation energy may be expressed as exactly the sum of pairwise correlation energies. In the case of no zeroth order degeneracy, the zeroth and first order terms vanish. The expression for the pairwise energies is an infinite sum, all terms of which are of the same sign. There is no numerical differencing. In the case of zeroth order degeneracy it is shown that the above statement concerning the second order energy still holds, but the expressions are a bit more complicated. It is shown that they ''almost'' reduce to a much simpler form. Also, the computation of the first order correlation energy is considered

    Optical lattices allow for tight three-dimensional confinement of neutral atoms in quasi-harmonic potentials and have become a standard tool in experimental quantum optics. Applications range from fundamental topics like metrology to applications in quantum communication and quantum information processing. Here we present an experimental characterization of the motional and internal energy eigenstates of optically trapped 87Rb atoms. We implement different spectroscopy techniques based on non-destructive hyperfine state detection using an optical cavity. Applying these techniques, we observe and explain a series of effects like the decoupling of the hyperfine spin due to a tensor lightshift and mechanical effects associated with a small non-orthogonality of the lattice axes. Furthermore, we succeed to exploit the latter for optical cooling of a single atom into the two-dimensional mechanical groundstate in an environment with restricted optical access.

    2015-10-30

    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 light 'bit'.

    In fiscal year 1990, Japanese economy maintained steady domestic civilian demands, and the real rate of economical growth became 5.7%. The total supply of primary energy increased by 5.3% as compared with that in the last year. The share of nuclear power recovered to 9.4% due to the increase of the capacity factor after the lapse of three years. The demand of electric power increased by 7.3% as compared with that in the previous year, and the share of nuclear power in the total generated electric power was 26.3%. The outlay of electric power industry related to atomic energy was 1735.4 billion yen, and 6% increase as compared with that in the previous year. The sales of mining and manufacturing industries related to atomic energy was 1768.1 billion yen and 2% increase as compared with that in the previous year. The construction cost of nuclear power stations was 658.3 billion yen and 17% increase. The civilian workers related to atomic energy in electric power, mining and manufacturing industries were 57687 persons and 7% increase. Kashiwazaki-Kariwa No. 2 plant (1100 MWe BWR) and No. 5 plant (1100 MWe BWR) of Tokyo Electric Power Co., Inc. started the operation, and installed nuclear power generation capacity reached 31.48 million kW of 39 plants.

    We describe a type of scanning electron microscope that works by directly imaging the electron field-emission sites on a nanotip. Electrons are extracted from the nanotip through a nanoscale aperture, accelerated in a high electric field, and focused to a spot using a microscale Einzel lens. If the whole microscope (accelerating section and lens) and the focal length are both restricted in size to below 10 μm, then computer simulations show that the effects of aberration are extremely small and it is possible to have a system with approximately unit magnification at electron energies as low as 300 eV. Thus a typical emission site of 1 nm diameter will produce an image of the same size, and an atomic emission site will give a resolution of 0.1-0.2 nm (1-2 A). Also, because the beam is not allowed to expand beyond 100 nm in diameter, the depth of field is large and the contribution to the beam spot size from chromatic aberrations is less than 0.02 nm (0.2 A) for 500 eV electrons. Since it is now entirely possible to make stable atomic sized emitters (nanopyramids), it is expected that this instrument will have atomic resolution. Furthermore the brightness of the beam is determined only by the field emission and can be up to 1x10 6 times larger than in a typical (high energy) electron microscope. The advantages of this low energy, bright-beam electron microscope with atomic resolution are described and include the possibility of it being used to rapidly sequence the human genome from a single strand of DNA as well as being able to identify atomic species directly from the elastic scattering of electrons

  1. An energy integrated, multi-microgrid, MILP (mixed-integer linear programming) approach for residential distributed energy system planning – A South Australian case-study

    Wouters, Carmen; Fraga, Eric S.; James, Adrian M.

    2015-01-01

    The integration of distributed generation units and microgrids in the current grid infrastructure requires an efficient and cost effective local energy system design. A mixed-integer linear programming model is presented to identify such optimal design. The electricity as well as the space heating and cooling demands of a small residential neighbourhood are satisfied through the consideration and combined use of distributed generation technologies, thermal units and energy storage with an optional interconnection with the central grid. Moreover, energy integration is allowed in the form of both optimised pipeline networks and microgrid operation. The objective is to minimise the total annualised cost of the system to meet its yearly energy demand. The model integrates the operational characteristics and constraints of the different technologies for several scenarios in a South Australian setting and is implemented in GAMS. The impact of energy integration is analysed, leading to the identification of key components for residential energy systems. Additionally, a multi-microgrid concept is introduced to allow for local clustering of households within neighbourhoods. The robustness of the model is shown through sensitivity analysis, up-scaling and an effort to address the variability of solar irradiation. - Highlights: • Distributed energy system planning is employed on a small residential scale. • Full energy integration is employed based on microgrid operation and tri-generation. • An MILP for local clustering of households in multi-microgrids is developed. • Micro combined heat and power units are key components for residential microgrids

    2017-10-01

    This paper presents an implementation of a Ceph file system (CephFS) use case at the ARC Center of Excellence for Particle Physics at the Terascale (CoEPP). CoEPP’s CephFS provides a posix-like file system on top of a Ceph RADOS object store, deployed on commodity hardware and without single points of failure. By delivering a unique file system namespace at different CoEPP centres spread across Australia, local HEP researchers can store, process and share data independently of their geographical locations. CephFS is also used as the back-end file system for a WLCG ATLAS user area at the Australian Tier-2. Dedicated SRM and XROOTD services, deployed on top of CoEPP’s CephFS, integrates it in ATLAS data distributed operations. This setup, while allowing Australian HEP researchers to trigger data movement via ATLAS grid tools, also enables local posix-like read access providing greater control to scientists of their data flows. In this article we will present details on CoEPP’s Ceph/CephFS implementation and report performance I/O metrics collected during the testing/tuning phase of the system.

  4. U.S. Radioecology Research Programs of the Atomic Energy Commission in the 1950s

    Reichle, D.E.

    2004-01-12

    This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. 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

    Dual energy technique for computerized microtomography shows itself as a promising method for identification of mineralogy on geological samples of heterogeneous composition. It can also assist with differentiating very similar objects regarding the attenuation coefficient, which are usually not separable during image processing and analysis of microtomographic data. Therefore, the development of a feasible and applicable methodology of dual energy in the analysis of microtomographic images was sought. - Highlights: • Dual energy technique is promising for identification of distribution of minerals. • A feasible methodology of dual energy in analysis of tomographic images was sought. • The dual energy technique is efficient for density and atomic number identification. • Simulation showed that the proposed methodology agrees with theoretical data. • Nondestructive characterization of distribution of density and chemical composition

  6. Theory of inelastic ion-atom scattering at low and intermediate energies

    Science.gov (United States)

    Schmid, G. B.; Garcia, J. D.

    1977-01-01

    Ab initio calculations are presented of inelastic energy loss and ionization phenomena associated with Ar(+)-Ar collisions at small distances of closest approach and for laboratory collision energies ranging from several keV to several hundred keV. Outer-shell excitations are handled statistically; inner-shell excitations are calculated from the viewpoint of quasidiabatic molecular orbital promotion. Auger electron yield, average state of ionization, and average inelastic energy loss are calculated per collision as a function of distance of closest approach of the collision partners for several laboratory collision energies. Average charge-state probabilities per collision partner are calculated as a function of the average inelastic energy loss per atom. It is shown that the structure in the data is due to the underlying structure in the inner-shell independent-electron quasimolecular promotion probabilities.

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

    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{sup +} 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.

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

    International Nuclear Information System (INIS)

    Forland, A.

    1995-01-01

    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

  13. The time-energy distribution of atoms in a radiation damage cascade

    1976-01-01

    The time-energy distribution of atoms in a cascade induced by a primary knock-on is obtained by solving the Boltzmann equation. A more general scattering law is used than has hitherto been possible which is based upon a rational approximation to the Thomas-Fermi model of atomic scattering. The virtue of this scheme is that it remains possible to obtain an exact, closed form solution but allows a more realistic description of the scattering process. Time moments of the distribution are obtained from which the slowing down time and associated variance can be calculated. It is shown that the complete time-energy distribution may be reconstructed from the moments. (author)

    2005-01-01

    Japan Atomic Energy Agency (JAEA) was established on October 1, 2005, after the merger of Japan Atomic Energy Research Institute and Japan Nuclear Cycle Development Institute. JAEA is the only governmental nuclear research and development institute in Japan. It will engage in research activities ranging from basic research to practical applications in the nuclear field and will operate research laboratories, reactors, a reprocessing plant and a fuel fabrication plant. At the same time, the Nuclear Nonproliferation Science and Technology Center (NPSTC) was also established inside of JAEA to conduct the studies on the strategy for nuclear nonproliferation studies. Five roles that JAEA should play for nuclear nonproliferation were identified and four offices were established in the center to carry out those five roles effectively. To conduct the research and development for nuclear nonproliferation efficiently, the center aims to be a 'Research Hub' based on Partnership' with other organizations. (author)

  16. Ground state potential energy surfaces around selected atoms from resonant inelastic x-ray scattering.

    Thermally driven chemistry as well as materials' functionality are determined by the potential energy surface of a systems electronic ground state. This makes the potential energy surface a central and powerful concept in physics, chemistry and materials science. However, direct experimental access to the potential energy surface locally around atomic centers and to its long-range structure are lacking. Here we demonstrate how sub-natural linewidth resonant inelastic soft x-ray scattering at vibrational resolution is utilized to determine ground state potential energy surfaces locally and detect long-range changes of the potentials that are driven by local modifications. We show how the general concept is applicable not only to small isolated molecules such as O2 but also to strongly interacting systems such as the hydrogen bond network in liquid water. The weak perturbation to the potential energy surface through hydrogen bonding is observed as a trend towards softening of the ground state potential around the coordinating atom. The instrumental developments in high resolution resonant inelastic soft x-ray scattering are currently accelerating and will enable broad application of the presented approach. With this multidimensional potential energy surfaces that characterize collective phenomena such as (bio)molecular function or high-temperature superconductivity will become accessible in near future.

    It is important for Atomic Energy Society of Japan which covers the wide fields related to atomic energy to know exactly what the youths who bear the next generation learn about atomic energy and what feeling they have. However, the attitude or the attempt of meeting young generation from such viewpoint was not sufficient so far. In the phenomena of 'away from atomic energy' recently pointed out frequently, the root seems to have existed long ago. In this feature article, from such critical mind, the present status and the plan for hereafter of atomic energy publicity activities for young generation and those concerned to education are made clear. The publicity activities for school education and young generation, the publicity activities for those concerned to education, the questionnaire of the consciousness about energy and environment, the open school activity of Atomic Energy Society of Japan, the nuclear reactor experiment and study for middle and high school teachers, the assembling of simplified GM counters and the experiment of measuring radiation, the activities of Plasnet for young generation and the exercise and seminar on radiation for high school students are reported. Japanese social system is at the root of atomic energy problem, and the effort to improve it contributes to innovate the constitution of whole Japan. (K.I.)

  18. Precision X-ray spectroscopy of kaonic atoms as a probe of low-energy kaon-nucleus interaction

    Shi H.

    2016-01-01

    Full Text Available 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.

  19. Electromagnetic-energy-density distribution around a ground-state hydrogen atom and connection with van der Waals forces

    International Nuclear Information System (INIS)

    Passante, R.; Power, E.A.

    1987-01-01

    A spinless hydrogen atom coupled to the electromagnetic field is considered within the context of nonrelativistic quantum electrodynamics. The atom-field interaction is taken in the minimal-coupling form and the Coulomb gauge is used. When the coupled system is in its ground state the electromagnetic field fluctuates away from the vacuum state and the atom has virtual admixtures from its uncoupled lowest eigenstate. The electric- and magnetic-field-energy densities that arise from the fluctuations are determined as functions of the distance from the atom. The relationship between these field-energy densities and the retarded long-range van der Waals forces is also discussed

  18. Protein structure prediction by all-atom free-energy refinement

    Science.gov (United States)

    Verma, Abhinav; Wenzel, Wolfgang

    2007-01-01

    Background The reliable prediction of protein tertiary structure from the amino acid sequence remains challenging even for small proteins. We have developed an all-atom free-energy protein forcefield (PFF01) that we could use to fold several small proteins from completely extended conformations. Because the computational cost of de-novo folding studies rises steeply with system size, this approach is unsuitable for structure prediction purposes. We therefore investigate here a low-cost free-energy relaxation protocol for protein structure prediction that combines heuristic methods for model generation with all-atom free-energy relaxation in PFF01. Results We use PFF01 to rank and cluster the conformations for 32 proteins generated by ROSETTA. For 22/10 high-quality/low quality decoy sets we select near-native conformations with an average Cα root mean square deviation of 3.03 Å/6.04 Å. The protocol incorporates an inherent reliability indicator that succeeds for 78% of the decoy sets. In over 90% of these cases near-native conformations are selected from the decoy set. This success rate is rationalized by the quality of the decoys and the selectivity of the PFF01 forcefield, which ranks near-native conformations an average 3.06 standard deviations below that of the relaxed decoys (Z-score). Conclusion All-atom free-energy relaxation with PFF01 emerges as a powerful low-cost approach toward generic de-novo protein structure prediction. The approach can be applied to large all-atom decoy sets of any origin and requires no preexisting structural information to identify the native conformation. The study provides evidence that a large class of proteins may be foldable by PFF01. PMID:17371594

    Full Text Available In 1955, the U.S. Information Service (USIS Tokyo produced a thirty-minute documentary film Blessing of Atomic Energy in commemoration of the tenth anniversary of the Atomic bombing of Hiroshima and Nagasaki. The film introduced how the Japanese government, researchers, and companies were using radioisotopes offered by the U.S. Argonne National Laboratory for the “peaceful” purposes in agriculture, medicine, hygiene, industry, and disaster prevention. The film also showed the mechanism of atomic power generation, and explained that it was already put into practice in the U.S. and Europe. The images of Japanese people enjoying the “blessing” of the “peaceful” use of atomic energy, ten years after the traumatic experience of A-bombs, were not only shown all over Japan, but also translated into different languages and shown in many countries, including the UK, Finland, Indonesia, Sudan, and Venezuela. The film was part of some fifty educational and documentary films produced for President Eisenhower’s “Atoms for Peace” campaign – a global information dissemination programs on the U.S. leadership in the civilian use of nuclear energy. This paper will explore the roles USIS films played in disseminating information on the “peaceful” use of nuclear energy in the early Cold War era.

    1980-01-01

    The most typical dispute on atomic energy processes takes place in Japan around seeking the annulment of permission of the installation of reactors, and nine cases on the atomic energy facilities for power generation are now in discussion. Nullification proceedings are stipulated in the law of administrative issue legal procedure. Under the law, the abolition of administrative activities can be sought only by the persons who have legal interests, which mean legally protected interests according to Japanese court decisions. The expected damage due to hot water discharge from reactors was not examined in the Ikata judgement, because hot water discharge would be discussed in the examination of permission under the Electricity Enterprises Act, according to the court. In other respects, court judgements cover all dangers of atomic energy and harmful effects of radiation. The most important point of discussion is emergency core cooling system, and Japanese special circumstances are found in that the counter measures against earthquakes are the major problem. In the Ikata case, the court held that waste treatment should be examined, and that the judgement of the government office to some degree on the method of reprocessing would suffice. The Ikata decision maintained that the standard of safety examination should depend upon the present level of science. The attitude of the court in the Ikata case was not clear as to whether the discretion of the government office may be permitted in safety judgement. (Okada, K.)

  5. Probing resonant energy transfer in collisions of ammonia with Rydberg helium atoms by microwave spectroscopy

    Science.gov (United States)

    Zhelyazkova, V.; Hogan, S. D.

    2017-12-01

    We present the results of experiments demonstrating the spectroscopic detection of Förster resonance energy transfer from NH3 in the X1A1 ground electronic state to helium atoms in 1sns 3S1 Rydberg levels, where n = 37 and n = 40. For these values of n, the 1sns 3S1 → 1snp 3PJ transitions in helium lie close to resonance with the ground-state inversion transitions in NH3 and can be tuned through resonance using electric fields of less than 10 V/cm. In the experiments, energy transfer was detected by direct state-selective electric field ionization of the 3S1 and 3PJ Rydberg levels and by monitoring the population of the 3DJ levels following pulsed microwave transfer from the 3PJ levels. Detection by microwave spectroscopic methods represents a highly state selective, low-background approach to probing the collisional energy transfer process and the environment in which the atom-molecule interactions occur. The experimentally observed electric-field dependence of the resonant energy transfer process, probed both by direct electric field ionization and by microwave transfer, agrees well with the results of calculations performed using a simple theoretical model of the energy transfer process. For measurements performed in zero electric field with atoms prepared in the 1s40s 3S1 level, the transition from a regime in which a single energy transfer channel can be isolated for detection to one in which multiple collision channels begin to play a role has been identified as the NH3 density was increased.

    We present a theoretical study of elastic and rotationally inelastic collisions of NH3 and ND3 with rare gas atoms (He, Ne, Ar, Kr, Xe) at low energy. Quantum close-coupling calculations have been performed for energies between 0.001 and 300 cm(-1). We focus on collisions in which NH3 is initially in the upper state of the inversion doublet with j = 1, k = 1, which is the most relevant in an experimental context as it can be trapped electrostatically and Stark-decelerated. We discuss the presence of resonances in the elastic and inelastic cross sections, as well as the trends in the inelastic cross sections along the rare gas series and the differences between NH3 and ND3 as a colliding partner. We also demonstrate the importance of explicitly taking into account the umbrella (inversion) motion of NH3 in order to obtain accurate scattering cross sections at low collision energy. Finally, we investigate the possibility of sympathetic cooling of ammonia using cold or ultracold rare gas atoms. We show that some systems exhibit a large ratio of elastic to inelastic cross sections in the cold regime, which is promising for sympathetic cooling experiments. The close-coupling calculations are based on previously reported ab initio potential energy surfaces for NH3-He and NH3-Ar, as well as on new, four-dimensional, potential energy surfaces for the interaction of ammonia with Ne, Kr, and Xe, which were computed using the coupled-cluster method and large basis sets. We compare the properties of the potential energy surfaces corresponding to the interaction of ammonia with the various rare gas atoms.

    We present the results of experiments demonstrating the spectroscopic detection of Förster resonance energy transfer from NH 3 in the X 1 A 1 ground electronic state to helium atoms in 1sns 3 S 1 Rydberg levels, where n = 37 and n = 40. For these values of n, the 1sns 3 S 1 → 1snp 3 P J transitions in helium lie close to resonance with the ground-state inversion transitions in NH 3 and can be tuned through resonance using electric fields of less than 10 V/cm. In the experiments, energy transfer was detected by direct state-selective electric field ionization of the 3 S 1 and 3 P J Rydberg levels and by monitoring the population of the 3 D J levels following pulsed microwave transfer from the 3 P J levels. Detection by microwave spectroscopic methods represents a highly state selective, low-background approach to probing the collisional energy transfer process and the environment in which the atom-molecule interactions occur. The experimentally observed electric-field dependence of the resonant energy transfer process, probed both by direct electric field ionization and by microwave transfer, agrees well with the results of calculations performed using a simple theoretical model of the energy transfer process.

    Energy levels and oscillator strengths are calculated for 3s-3p and 3p-3d transition arrays in Ti X, isoelectronic to Al I. The energy levels are obtained by the Slater-Condon theory of atomic structure, including explicitly the strong configuration interactions. The results are presented both in numerical tables and in diagrams. In the tables, the observed data are included for comparison, where available. The calculated weighted oscillator strengths (gf-value) are also displayed in figures, where the weighted oscillator strengths are plotted as a function of wavelength. (author)

    2000-07-03

    We study the behavior of shell effects, like pairing correlations and shape deformations, with the excitation energy in atomic nuclei. The analysis is carried out with the finite temperature Hartree-Fock-Bogoliubov method and a finite range density dependent force. For the first time, properties associated with the octupole and hexadecupole deformation and with the superdeformation as a function of the excitation energy are studied. Calculations for the well quadrupole deformed 164Er and 162Dy, superdeformed 152Dy, octupole deformed 224Ra, and spherical 118Sn nuclei are shown. We find, in particular, the level density of superdeformed states to be 4 orders of magnitude smaller than for normal deformed ones.

    Diaz de la Rubia, T.; Guinan, M.W.

    1991-01-01

    We have performed molecular dynamics computer simulation studies of displacement cascades in Cu at low temperature. For 25 keV recoils we observe the splitting of a cascade into subcascades and show that cascades in Cu may lead to the formation of vacancy and interstitial dislocation loops. We discuss a new mechanism of defect production based on the observation of interstitial prismatic dislocation loop punching from cascades at 10 K. We also show that below the subcascade threshold, atomic mixing in the cascade is recoil-energy dependent and obtain a mixing efficiency that scales as the square root of the primary recoil energy. 44 refs., 12 figs

    Misreporting is common when collecting dietary intake data, although relatively little is known about the types of foods misreported among children. The present study aimed to identify differences in the reporting of food types between plausible and misreporters of energy intake in a national nutrition survey of Australian children. Dietary data were collected using a 24-h recall from 4826 children aged 2-16 years who were participating in the 2007 Australian National Children's Nutrition and Physical Activity Survey. Misreporters of energy intake were classified using the Goldberg criteria. Differences in the reporting of a range of food types were examined between plausible, under- and over-reporters. Compared with plausible reporters, under-reporters reported less frequent consumption and smaller quantities of consumption of both core and noncore foods. Older children (self-report) under-reported a larger selection of noncore foods than younger children (parental report). Over-reporters reported similar percentages of consumption of many core and noncore foods, with some exceptions. The quantities consumed by over-reporters were generally much larger and this was evident in younger and older children. Compared with plausible reporters, under-reporters had significantly higher intakes of protein and starch but lower intakes of sugar and fat, as percentage energy, than plausible reporters, whereas over-reporters had higher fat and lower carbohydrate intakes. Differences in the reporting of food types were common between plausible, under- and over-reporters of energy intake by children (or their parents) and were not restricted to noncore foods. © 2013 The British Dietetic Association Ltd.

  15. Atomic energy training centres in Latin America. Report of IAEA Mission

    International Nuclear Information System (INIS)

    1959-01-01

    In January 1958, the Brazilian representative on the Board of Governors of the International Atomic Energy Agency - supported by the Governors from Argentina and Guatemala - proposed that a study should be made of the possibility of setting up one or more atomic energy training centres in Latin America. Countries now having facilities that could be used for co-operative training are Argentina, where rapid strides are being made in building up an integrated atomic energy centre in the Buenos Aires; Brazil, which has successfully established a physical science nuclear laboratory and a radio-biology centre; Venezuela, with a medico-biological centre from which much may be expected; and Mexico, where nuclear science courses are to be provided by the University of Mexico. The report discusses two alternatives for the establishment of training centres: 'specialized centres' or 'integrated centres' and concludes that the integrated centre is the preferable one however specialized centres stand a much higher chance of being staffed successfully. They are inherently smaller and consequently costs for facilities and equipment are much less. In addition use might be made of existing facilities. It is stated that one of the specialized atomic energy training centres to be established might well be in the field of radio-botany. Agriculture is a major source of income throughout Latin America. There are many agricultural schools and experimental stations throughout the region and also the Inter-American Institute of Agricultural Science at Turrialba, Costa Rica. The authors of the report concluded that a training centre in radio-botany should provide vitally needed knowledge and vitally needed specialists to all the agricultural installations in Latin America. The report recommends that (1) the Agency should meet the requests of Latin American universities by, for example, supplying equipment and sending experts; (2) at least one specialized training centre should be established

    2005-01-01

    The QED contribution to the energies of the circular (n,l=n-1), 2≤n≤13, transitions have been calculated for several kaonic atoms throughout the periodic table, using the current world-average kaon mass. Calculations were done in the framework of the Klein-Gordon equation, with finite nuclear size, finite particle size, and all-order Uelhing vacuum polarization corrections, as well as Kaellen and Sabry and Wichmann and Kroll corrections. These energy level values are compared with other computed values. The circular transition energies are compared with available measured and theoretical transition energies. Electron screening is evaluated using a Dirac-Fock model for the electronic part of the wave function. The effect of electronic wave-function correlation is evaluated

  17. Electrode surface engineering by atomic layer deposition: A promising pathway toward better energy storage

    2016-04-29

    Research on electrochemical energy storage devices including Li ion batteries (LIBs), Na ion batteries (NIBs) and supercapacitors (SCs) has accelerated in recent years, in part because developments in nanomaterials are making it possible to achieve high capacities and energy and power densities. These developments can extend battery life in portable devices, and open new markets such as electric vehicles and large-scale grid energy storage. It is well known that surface reactions largely determine the performance and stability of electrochemical energy storage devices. Despite showing impressive capacities and high energy and power densities, many of the new nanostructured electrode materials suffer from limited lifetime due to severe electrode interaction with electrolytes or due to large volume changes. Hence control of the surface of the electrode material is essential for both increasing capacity and improving cyclic stability of the energy storage devices.Atomic layer deposition (ALD) which has become a pervasive synthesis method in the microelectronics industry, has recently emerged as a promising process for electrochemical energy storage. ALD boasts excellent conformality, atomic scale thickness control, and uniformity over large areas. Since ALD is based on self-limiting surface reactions, complex shapes and nanostructures can be coated with excellent uniformity, and most processes can be done below 200. °C. In this article, we review recent studies on the use of ALD coatings to improve the performance of electrochemical energy storage devices, with particular emphasis on the studies that have provided mechanistic insight into the role of ALD in improving device performance. © 2016 Elsevier Ltd.

    1984-01-01

    Since the summer of the last year, the problems in the relation with developing countries have been actively discussed in the Atomic Energy Commission, Japan Atomic Industrial Forum Inc., and the Ministry of International Trade and Industry. As the background of this tendency, it is pointed out that Japanese nuclear industry has grown up to the level comparable with European and American counterparts and capable of advancing into the world market as the exporter of nuclear facilities, on the other hand, that Asian countries expect Japanese technical and economical power also in the field of atomic energy. In this report, the technical cooperation of the IAEA on funds, the dispatch of specialists, the supply of materials and training, the technical cooperation of Japanese International Cooperation Agency on the acceptance of trainees, the dispatch of specialists and others, and the fundamental way of thinking about the technical cooperation on government base are reported. It is very important to grasp the true needs of a partner country when a project is selected. In the cooperation, the effort of self-help by a developing country must be the major premise. (Kako, I.)
