    Act to provide for the establishment of an Atomic Energy Authority and an advisory committee to advise such authority, to specify the power, duties, rights and functions of such authority, and to provide for matters connected therewith or incidental thereto

  4. Decommissioning in the United Kingdom Atomic Energy Authority

    International Nuclear Information System (INIS)

    The United Kingdom Atomic Energy Authority's policy on decommissioning is described. Several fission reactors have already been taken out of service and the state of decommissioning is given. Estimates of the volume of decommissioning wastes are made. The wastes will be either intermediate-level or low-level wastes. Research and development programmes have been undertaken to allow decommissioning to be safe and cost-effective. Some of the contaminated facilities have been decontaminated and re-used. (U.K.)

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

    International Nuclear Information System (INIS)

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

  6. Statutory Instrument No. 478, The Atomic Energy Authority Act 1971 (Appointed Day) Order 1971

    International Nuclear Information System (INIS)

    This Order fixes 1 April 1971 as the appointed day for the purposes of sections 1 and 2 of the Atomic Energy Authority Act 1971 and, accordingly, it is upon that date that the transfers provided for in that Act of parts of the undertaking of the United Kingdom Energy Authority to British Nuclear Fuels Limited and the Radiochemical Centre Limited took place.

  8. The Practice of Waste Disposal in the United Kingdom Atomic Energy Authority

    International Nuclear Information System (INIS)

    The United Kingdom Atomic Energy Authority operates establishments in locations ranging from the South of England to the North coast of Scotland. The functions of these establishments include the production and processing of nuclear fuels, the production of electricity and isotopes for commercial sale, the development of new types of reactors and the conduct of research in all the associated fields. The Authority therefore has a wide variety of wastes to deal with and they arise in a number of different places. The main high-activity wastes, both liquid and solid, are stored in special tanks and containers, while the low-activity large-volume liquid wastes are released in carefully controlled amounts to the sea or to rivers. Low-and medium- activity solid wastes are buried in selected areas where there will be no interference with water supplies, or sunk on to the sea bed. The paper summarizes the methods in use and gives typical quantities of liquid and solid waste arising annually for disposal by the various methods. (author)

  9. The Federal Government's authority to give instructions in the licensing procedure under atomic energy law - conditions and legal protection

    International Nuclear Information System (INIS)

    In the atomic energy law of the F.R.G., the supreme federal authority on principle has the unlimited right to give instructions. This authority, however, is restricted to the subject scope of the Atomic Energy Act and the relevant statutory ordinances, and is again limited by the principle of reasonableness, and the principle of mutual consideration of the interests of Land governments and those of the Federal Government. A dispute on the legality of instructions given by the Federal Minister of the Environment, Nature Conservation and Reactor Safety to a supreme Land authority (e.g. in case of a decision on a further partial license for the Kalkar FBR in accordance with section 7 Atomic Energy Act) within the framework of the execution of federal laws is to be regarded as a dispute under public law between the Federal Government and the Land on matters of constitutional law. (Exclusive) competence of the Federal Administrative Court is excluded, and likewise is a 'dual jurisdiction' of the Federal Constitutional Court and the Federal Administrative Court. (orig./HSCH)

  10. A Survey of the Methods Used in the United Kingdom Atomic Energy Authority For The Determination Of Radionuclides In Urine

    International Nuclear Information System (INIS)

    With the co-operation of analytical, health physics and medical staff, a survey has been made throughout the United Kingdom Atomic Energy Authority of current practice in urine analysis for radionuclides. The elements which are of greatest importance in the UKAEA programmes of urine analvsis are plutonium, uranium, tritium and fission products (notably strontium-90 and caesium-137). Other radionuclides dealt with are polonium-210, radium-226, protactinium-231, phosphorus-32, carbon-14, sulphur-35, americium-241 and thorium. In assessing the function and scope of urine analysis, the factors affecting the choice of a suitable analytical method are discussed. The sensitivity and precision of the method must be adequate in relation to the maximum permissible body burden, the excretion rate and the sampling frequency; the method must be sufficiently specific or selective to eliminate the possibility of interference by other radionuclides; and finally, the cost must be assessed in relation to all these factors, and also to the speed and convenience of the method. The sensitivity required for each radionuclide is calculated from the maximum permissible body burden by applying a representative urinary excretion rate, based on the best data available. The methods of urine analysis which are currently used in the United Kingdom Atomic Energy Authority are fully described. According to the calculated requirements for sensitivity, the best methods in use are capable of quantitatively detecting, from urinary excretion, internal contamination with one-tenth of the maximum permissible body burden of any of the above radionuclides, and with one-hundredth of the maximum permissible body burden in the case of enriched uranium, tritium, polonium-210 or caesium-137.

  11. Is there a binding link between decisions of the atomic energy authority and criminal law?

    International Nuclear Information System (INIS)

    The paper analyses the court decision on the Alkem case, which acquitted the Alkem plant operators of the charge of infringement of section 327 Penal Code, not for legal reasons, but for lack of evidence for some facts considered essential by the court. The paper discusses the charge and the judgment, the issue of justification in this case, and items such as preliminary consent by an authority, misuse of rights, objections based on criminal law, the dilution of the administrative (law) accessoriness. (RST)

  12. The Federal authority to give instructions for the execution of Federal laws by the Lands, as shown by the administration in the field of atomic energy law

    International Nuclear Information System (INIS)

    The article discusses legal problems in the field of atomic energy law arising from the Federal authority to give instructions, discussing the required form of instructions as defined by the Constitution, the scope of the authority, the binding force of instructions, legal remedies available to instructed licensing authorities, and means of enforcement provided by the law. Art. 85, III of the Constitution defining this Federal authority has been gaining in significance in the wake of the political events that broke up the consensus in West Germany about the peaceful utilization of atomic energy. The commissioning of the SNR 300 (Kalkar) has been the first event in 1979 to induce a controversy about atomic energy, and since then the Alkem/Nukem affair and the dispute over it between the Land Hesse and the Federal government, and recently the instruction of the Federal Ministry of Reactor Safety to the Land government of Schleswig-Holstein, for re-startup of the Brokdorf reactor, have added to the topicality of this Article. The licensing procedure for the Kalkar reactor still is in progress, but the Land government of North-Rhine Westphalia has brought an action against the Federal Government before the Federal Constitutional Court. The action is against a Federal instruction of May 1988, prohibiting the Land from ordering an expert opinion by the TUeV (Technical Inspection Association) for investigating possible similarities between the Chernobyl and the Kalkar reactor stations.

  14. Atomic energy utilization

    International Nuclear Information System (INIS)

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

  12. 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...

  14. Preemption - atomic energy

    International Nuclear Information System (INIS)

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

  1. Design of atomic energy information network system

    International Nuclear Information System (INIS)

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

  2. Atomic energy indemnification system in Japan

    International Nuclear Information System (INIS)

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

  4. Atomic energy in Latin America

    International Nuclear Information System (INIS)

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

  15. 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.

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

    International Nuclear Information System (INIS)

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

  19. Ps-atom scattering at low energies

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

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

    International Nuclear Information System (INIS)

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

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

The third report describes the utilization of passive, dry-air cooling systems for major installations, such as cooling the containment of the Westinghouse AP-600 advanced pressurized water reactor. Good and economic passive dry-air cooling systems would be among the best solutions for containment cooling at inland sites, especially in arid areas. Noninvasive medical diagnostic methods utilizing radioactive materials have been standard far many years. The most common of these relies on using a gamma camera to determine the distribution of injected or ingested radioisotope-labeled compounds in the human body. The 30-year-old camera technology, although vastly improved over the years, is still handicapped by energy and spatial resolution limitations of the detectors, by the size and bulk of the instrument and other technical problems. The need for further development of an improved, more efficient and compact imaging system is clear. Such a system, based on solid-state detectors, is described in the last report. I would like to commend the authors of the selected presentations as well as the entire staff of the Israel Atomic Energy Commission for their valuable contributions and achievements and wish them all further success in their continuing fruitful endeavors

  10. International Atomic Energy Agency activities in decommissioning

    International Nuclear Information System (INIS)

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

    2016-01-01

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

  13. Peaceful uses of atomic energy

    International Nuclear Information System (INIS)

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

  15. Zero-point energy of ultracold atoms

    Science.gov (United States)

    Salasnich, Luca; Toigo, Flavio

    2016-06-01

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

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.

    Burrage, Clare; Hinds, E A

    2015-01-01

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

  6. Current trend of atomic energy development in Japan - 2

    International Nuclear Information System (INIS)

    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.

    2016-04-01

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

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

  16. The licensing procedure under Atomic Energy Law

    International Nuclear Information System (INIS)

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

    The design details of an alpha-particle counting set-up at a defined solid angle (ACS-DSA) constructed in Radionuclide Metrology Department at TAEK-SANAEM for use in the primary standardization of radioactive solutions and determination of nuclear decay data of alpha-particle emitters is presented. The counting system is designed such that the solid angle is very well-defined and directly traceable to the national standards. The design involves mechanical construction of different parts like the source chamber, various coaxial flanges, and circular diaphragms in front of the passivated implanted planar silicon (PIPS®) detector, distance tubes, a digital caliper and a sliding piston to allow for different measurement configurations. All geometric configurations are easily changeable and characterisable with high accuracy which facilitates the solid angle calculation. A mixed alpha source was counted to check performance of assembled ACS-DSA system and good energy resolution and low peak tailing in the alpha energy spectrum was observed for small diaphragm apertures and far source-to-detector geometries.

  2. European atomic energy law. Nuclear energy laws. 2. ed.

    International Nuclear Information System (INIS)

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

  3. The industrial development of atomic energy

    International Nuclear Information System (INIS)

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

    2015-01-01

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

  5. Constitutionality of the Atomic Energy Act

    International Nuclear Information System (INIS)

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

The equality of all six CC bond lengths, despite the alternating double and single bonds, and the surplus (resonance) energy, led to the suggestion of two resonanting structures.

  8. Atomic energy law in the Federal Republic of Germany

    International Nuclear Information System (INIS)

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

Here, the new atomic structure shows that the bond length equality is due to three carbon atoms with double bond radii bound to three other carbon atoms with resonance bond radii (as in graphene). Consequently, there are two kinds of CH bonds of slightly different lengths. The bond energies account for the resonance energy.

  11. 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)

    Atomic energy law remains a living, fascinating subject matter. Nearly 200 participants were convinced of this impression at the 14th 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 14th 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 14th 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, material

  12. Energy management in seaports: A new role for port authorities

    International Nuclear Information System (INIS)

    Ports are characterised by the geographical concentration of high–energy demand and supply activities, because of their proximity to power generation facilities and metropolitan regions, and their functions as central hubs in the transport of raw materials. In the last decades the need to better understand and monitor energy-related activities taking place near or within the port has become more apparent as a consequence of the growing relevance of energy trades, public environmental awareness and a bigger industry focus on energy efficiency. The uptake in the port sector of innovative technologies, such as onshore power supply, or alternative fuels, such as LNG, and the increasing development of renewable energy installations in port areas, also calls for more attention to energy matters within port management. So far, however, few port authorities have actively pursued energy management strategies. The necessity for port authorities to actively manage their energy flows stems from their efforts to plan, coordinate and facilitate the development of economic activities within the port, and as a consequence of the heavier weight that sustainability is given within the port management strategies. Through the analysis of the experiences of two European ports, Hamburg and Genoa, that have already attempted to coordinate and rationalise their energy needs, this paper will argue that for the ports of the future active energy management can offer substantial efficiency gains, can contribute to the development of new alternative revenue sources and in the end, improve the competitive position of the port. - Highlights: • Port authorities are required to engage in energy management in order to diversify and respond to environmental pressure. • Energy management in ports has not been investigated sufficiently and offers opportunities for cost savings. • Port authorities can promote energy management by coordinating power generation, energy use and the uptake of

  15. Atomic energy policy in fiscal year 1985

    International Nuclear Information System (INIS)

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

  1. Information policies of nuclear energy authorities in Switzerland

    International Nuclear Information System (INIS)

    The nuclear energy authorities inform the general public openly and without delay, within the bounds of the legislative and licensing procedures, about all important decisions and occurrences. In addition, the nuclear supervisory board (Swiss Federal Nuclear Safety Inspectorate, HSK) provides details regarding its supervisory activities, mainly in the form of annual reports and by replying to questions from the media. The National Cooperative for the Storage of Radioactive Waste, Nagra, is particularly active with regard to communication. Special importance is also attached to the notification of government authorities and the media in the event of a malfunction in a nuclear power plant, and extensive preparations are being made within the framework of emergency planning for handling such an occurrence. In addition to the government authorities, there are a number of other offices which regularly provide information to the general public on matters related to nuclear energy. (author). 1 tab., 1 fig

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

  6. Young students's opinion about atomic energy

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

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

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

    We study three-body recombination of Ba$^+$ + Rb + Rb in the mK regime where a single $^{138}$Ba$^{+}$ ion in a Paul trap is immersed into a cloud of ultracold $^{87}$Rb atoms. We measure the energy dependence of the three-body rate coefficient $k_3$ and compare the results to the theoretical prediction, $k_3 \\propto E_{\\textrm{col}}^{-3/4}$ where $E_{\\textrm{col}}$ is the collision energy. We find agreement if we assume that the non-thermal ion energy distribution is determined by at least two different micro-motion induced energy scales. Furthermore, using classical trajectory calculations we predict how the median binding energy of the formed molecules scales with the collision energy. Our studies give new insights into the kinetics of an ion immersed into an ultracold atom cloud and yield important prospects for atom-ion experiments targeting the s-wave regime.

Thus in this paper authors succeeded in extending the basic applications of SUSY and Electroweak theory to atomic level. With further research and analysis, the hidden secrets of electroweak unification can be understood very easily.

    2001-01-01

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

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

    2004-08-20

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

    2014-12-01

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

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

    2016-08-01

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

    The NASA/Baltimore Applications Project operating at the Goddard Space Flight Center was called upon by the Housing Authority of Baltimore City to consider the problems of providing low cost public housing because of increased energy costs and suggest methods for correction and alleviation. The first step chosen was to elicit as many different options for solution as possible through means of a Public Housing Energy Workshop held in Easton, Md. in September 1980. A final role for the Workshop was a listing and qualifying of each alternative as to its suitability and cost. Specific areas were examined by three panels: (1) Systems, (2) Conservation and Motivation, and (3) Fuels. Each panel was made up of persons from differing but appropriate backgrounds; membership was not restricted to housing people alone. A summary of their deliberations is given - it will be used as a stepping stone to further selection and implementation of alternatives.

    2016-08-01

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

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

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

    International Nuclear Information System (INIS)

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

  13. An atomic clockwork using phase dependent energy shifts

    CERN Document Server

    De Munshi, D; Mukherjee, M

    2011-01-01

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

    2003-01-01

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

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

    International Nuclear Information System (INIS)

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

  3. Basic Law and Atomic Energy Law

    International Nuclear Information System (INIS)

    The author avails himself of the by now controversial jurisdiction on partial licences issued for nuclear power plants to argue relevant provisions of the Basic Law and to include facts which are related to the Basic Law. This is also necessary for reasons of social policy, since such a juridicial decision produces an effect which spreads far beyond the litigants. In a constitutional state that has to stand the test in the conflict arising between human rights and technical progress, the controversy on basic rights has to form a part of the trial and of the opinion. There are two sides to the rule of law: The citizen's obligation not to use violence, and his right to be strictly protected by the Basic Law. (HSCH)

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

    2002-01-01

    Threshold energies of sputtering of negative cluster ions from the Si(111) surface were measured at bombardment by Cs sup + , Rb sup + , and Na sup + ions with energy of 0.1-3.0 keV. These results are compared with the calculations of the similar thresholds by Bohdansky etc. formulas (3) for clusters Si sub n sup - and Cu sub n sup - with n=(1-5) and also for B, C, Al, Si, Fe, Cu atoms. Threshold energies of sputtering for the above elements were also estimated using the data from (5). Satisfactory agreement between the experimental and theoretical results was obtained. (author)

  13. Correlated energy transfer between two ultracold atomic species

    Science.gov (United States)

    Krönke, Sven; Knörzer, Johannes; Schmelcher, Peter

    2015-05-01

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

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

  3. The World Power Conference and atomic energy

    International Nuclear Information System (INIS)

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

  4. Progression of technology education for atomic energy engineering in Tsuyama National College of Technology

    International Nuclear Information System (INIS)

    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. (author)

    International Nuclear Information System (INIS)

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

  9. The International Atomic Energy Agency Nuclear Security Education Strategies

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

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

    2015-01-01

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

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

    2006-01-01

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

  16. Challenges of atomic energy regulation in Indian context

    International Nuclear Information System (INIS)

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

    Atomic energy law remains a living, fascinating subject matter. Nearly 200 participants were convinced of this impression at the 14{sup 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{sup 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{sup 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

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

    International Nuclear Information System (INIS)

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

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

    1998-01-01

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

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

    International Nuclear Information System (INIS)

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

  11. World situation of atomic energy and nuclear fuel cycle

    International Nuclear Information System (INIS)

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

  12. Scattering of low-energy neutrinos on atomic shells

    International Nuclear Information System (INIS)

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

  13. Opinions of Cordoba's politicians and journalists on atomic energy

    International Nuclear Information System (INIS)

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

In addition, paragraph 7 Atomic Energy Act introduces a new substantive obligation of the operators of nuclear power plants. The author of the contribution reports on whether paragraph 7 Atomic Energy Act provides additional nuclear protection or reduces the potential protection by law and jurisprudence.

  18. Energy distributions for ionization in ion-atom collisions

    CERN Document Server

    Amaya-Tapia, A

    2016-01-01

    In this paper we discuss how through the process of applying the Fourier transform to solutions of the Schr\\"odinger equation in the Close Coupling approach, good results for the ionization differential cross section in energy for electrons ejected in ion-atom collisions are obtained. The differential distributions are time dependent and through their time average, the comparison with experimental and theoretical data reported in the literature can be made. The procedure is illustrated with reasonable success in two systems, $p+H$ and $p+He$, and is expected to be extended without inherent difficulties to more complex systems. This allows advancing in the understanding of the calculation of ionization processes in ion-atom collisions.

    The MidSTAR-2 satellite, to be built at the US Naval Academy as a follow-on to the successful MidSTAR-1 satellite (http://web.ew.usna.edu/midstar/), will launch in 2011 and carry three Goddard Space Flight Center (GSFC) experiments developed under Goddard's Internal Research and Development (IRAD) program. One of these GSFC instruments, the Miniature Imager for Neutral Ionospheric atoms and Magnetospheric Electrons (MINI-ME) builds on the heritage of the Goddard-developed Low-Energy Neutral Atom (LENA) imager launched on the IMAGE spacecraft in 2000. MINI-ME features a Venetian-blind conversion surface assembly that improves both light rejection and conversion efficiency in a smaller and lighter package than LENA making this an highly effective instrument for viewing solar wind charge exchange with terrestrial and planetary exospheres. We will describe the MINI-ME prototyping effort and its science targets.

This method is characterized by the calculation of single-particle levels in an extended spherical Woods-Saxon potential, the extraction of crude shell energy, the refinement of crude shell energy due to residual interactions, and the incorporation into a mass formula. Here, we report the advance of this work focusing especially on nuclear deformations, and give some preliminary results and remarks. (author)

  1. Atomic Oxygen Energy in Low Frequency Hyperthermal Plasma Ashers

    Science.gov (United States)

    Banks, Bruce A.; Miller, Sharon K R.; Kneubel, Christian A.

    2014-01-01

    Experimental and analytical analysis of the atomic oxygen erosion of pyrolytic graphite as well as Monte Carlo computational modeling of the erosion of Kapton H (DuPont, Wilmington, DE) polyimide was performed to determine the hyperthermal energy of low frequency (30 to 35 kHz) plasma ashers operating on air. It was concluded that hyperthermal energies in the range of 0.3 to 0.9 eV are produced in the low frequency air plasmas which results in texturing similar to that in low Earth orbit (LEO). Monte Carlo computational modeling also indicated that such low energy directed ions are fully capable of producing the experimentally observed textured surfaces in low frequency plasmas.

  8. Low-energy scattering of electrons by atomic oxygen

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

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

  19. Neutron capture therapy for cancer: development at the National Atomic Energy Commission

    International Nuclear Information System (INIS)

    Boron neutron capture therapy (BNCT) involves the concurrent presence of a flux of neutrons of adequate energy and Boron 10 as a capture agent. They interact to damage tumor cells but fail to produce significant damage to healthy tissue because the destructive effect occurs mainly in the tumor cells that have selectively accumulated boron. This technique is applied for the treatment of brain tumors of the glioblastoma multiform type and melanoma in different locations. The aim of this project at CNEA is to develop the technological, scientific, clinical know-how and facilities to undertake clinical trials in Argentina. The development of the irradiation facility, the clinical beam and dosimetry was developed at the RA-6 reactor, Bariloche Atomic Center. Treatment planning, instrumentation for the neutron beam, boron measurements, neutron beam for small animal irradiation at the RA-1 reactor and basic research in radiobiology, microdosimetry and autoradiography were developed at Constituyentes Atomic Center. It is also conducted an intense activity in accelerator based BNCT. The infusions to be injected to the patients are prepared at Ezeiza Atomic Center. The clinics of BNCT radiotherapy is developed at the Roffo Institute of Oncology and the neurosurgery at the Argerich Hospital. At present, the project is close to start in the following months to treat melanoma in the limbs, when the authorization procedure is completed. (author)

    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. PMID:26293958

    1997-01-01

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

  7. Disposal of radioactive wastes arising in the United Kingdom from the peaceful uses of atomic energy

    International Nuclear Information System (INIS)

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

  8. The Hanau atomic energy laws. Nuclear fuel fabrication and the administrative law system

    International Nuclear Information System (INIS)

    The review concentrates on administrative law aspects in the discussion of problems relating to the licences and preliminary notices of approval issued for the Hanau nuclear industry. The authors deal with the licences granted in 1974 (according to sec. 9 Atomic Energy Act), with the extended licensing requirements of sec. 7 Atomic Energy Act as amended by the 3rd amendment (concerning fabrication and handling of nuclear fuels), and the criminal court proceedings examining the conduct of the Alkem management and senior officers of the Hessian Ministry of Economics. Specific aspects investigated in the review include continuation of existing operations in accordance with transitory provisions, replacement of existing by new installations, and preliminary notice of approval. The preliminary notices of approval given up to the date of December 31, 1977 are said to have been illegal and extinct at that date, but the court's decision to abstain from punishment is accepted. The authors outline some possibilities of giving more concrete shape to the judicial control by administrative courts. (RST)

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

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

    The MidSTAR-2 satellite, to be built at the US Naval Academy as a follow-on to the successful MidSTAR-1 satellite, will launch in 2011 and carry three Goddard Space Flight Center (GSFC) experiments developed under Goddard's Internal Research and Development (IRAD) program. One of these GSFC instruments, the Miniature Imager for Neutral Ionospheric atoms and Magnetospheric Electrons (MINI-ME) builds on the heritage of the Goddard-developed Low-Energy Neutral Atom (LENA) imager launched on the IMAGE spacecraft in 2000. MINI- ME features a Venetian-blind conversion surface assembly that improves both light rejection and conversion efficiency in a smaller and lighter package than LENA making this an highly effective instrument for viewing solar wind charge exchange with terrestrial and planetary exospheres. We will describe the MINI-ME prototyping effort and its science targets, also including time variability of ENA fluxes and charge-exchange interactions in the upper atmosphere from the terrestrial ring current source.

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

    Energy Technology Data Exchange (ETDEWEB)

    Charles H. Skinner

    2008-02-27

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

    International Nuclear Information System (INIS)

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

  1. Higher Ionization Energies of Atoms in Density Functional Theory

    CERN Document Server

    Argaman, Uri; Kraisler, Eli

    2014-01-01

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

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

    Science.gov (United States)

    Nedolya, Anatoliy V; Bondarenko, Natalya V

    2016-12-01

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

    Koontz, S. L.; Nordine, Paul

    1990-01-01

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

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

    International Nuclear Information System (INIS)

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

  13. Atomic-powered democracy: Policy against politics in the quest for American nuclear energy

    International Nuclear Information System (INIS)

    This dissertation focuses on the relationship of American nuclear energy to democracy. It examines whether the nuclear policy processes have furthered the legitimacy-government accountability and citizen participation-which the democratic institutes are based. Nuclear policy and its institutions have placed severe limitations on democratic practices. Contravened democracy is seen most clearly in the decoupling of policy from politics. Decoupling refers to the weakening of institutional linkages between citizens and government, and to the erosion of the norms that ground liberal democracy. Decoupling is manifested in policy centralization, procedural biases, technical rationality, and the spatial displacement of conflict. Decoupling has normative implications: While federal accountability was limited and citizen participation was shackled, other major groups enjoyed privileged access to policy making. The decoupling of nuclear policy from politics arose within the context of US liberal-democratic capitalism. The federal government pursued its own goals of defense and world leadership. Yet, it was not structurally autonomous from the hegemony of the political-economic context. Economically, the Atomic Energy Act did not permit federal agencies to directly invest in power plant construction, and did not authorize them to commercially generate electricity. Private industry was structurally placed to domesticate the atom. Politically, the liberal-democratic system hampered an unquestioning pursuit of atomic energy. Federal institutions have been forced to heed some of the anti-nuclear concerns. The pervasive influence of the US political economy on nuclear policy has come to transgress democracy. Nuclear power's growth faltered during the 1970s. The political and economic constraints on federal actions have limited the means available to revive a becalmed nuclear industry; this has exerted strong pressure on federal institutions to decouple policy from participation

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

    2011-01-01

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

    International Nuclear Information System (INIS)

    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)

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

    2016-07-01

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

    Barklem, Paul S

    2016-01-01

    A theoretical method for the estimation of cross sections and rates for excitation and charge transfer processes in low-energy hydrogen atom collisions with neutral atoms, based on an asymptotic two-electron model of ionic-covalent interactions in the neutral atom-hydrogen atom system, is presented. The calculation of potentials and non-adiabatic radial couplings using the method is demonstrated. The potentials are used together with the multi-channel Landau-Zener model to calculate cross sections and rate coefficients. The main feature of the method is that it employs asymptotically exact atomic wavefunctions, which can be determined from known atomic parameters. The method is applied to Li+H, Na+H, and Mg+H collisions, and the results compare well with existing detailed full-quantum calculations. The method is applied to the astrophysically important problem of Ca+H collisions, and rate coefficients are calculated for temperatures in the range 1000-20000 K.

  6. Collective processes in heavy-ion collisions with atomic nuclei. Dissipation of energy and angular momentum

    International Nuclear Information System (INIS)

    The collective processes in collision of heavy-ions with atomic nuclei are discussed. Measured data on the S+Ti collision at Esub(LAB)=105, 130 and 144 MeV have been analysed in terms of a ''fission-like'' processes which seem to be a special case of deep inelastic collisions whose total available kinetic energy is completely dissipated. Applying transport theory it was possible to introduce a ''clock'' for measuring the time scale of nuclear processes in collision of heavy-ions by measuring the FWHM of mass distribution of emitted reaction products. Experimental data on continuum gamma spectra from Cu+Au collision at Esub(LAB)=400 MeV are presented and the angular momentum dissipation in this reaction is discussed. (author)

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

  8. The International Atomic Energy Agency: activities and relationship with Mexico

    International Nuclear Information System (INIS)

    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.

    2016-01-01

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

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

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

    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

    Light elements such as alkali metal (lithium, sodium) or halogen (fluorine, chlorine) are present in various substances and indeed play significant roles in our life. Although atomic behaviours of these elements are often a key to resolve chemical or biological activities, they are hardly visible in transmission electron microscope because of their smaller scattering power and higher knock-on probability. Here we propose a concept for detecting light atoms encaged in a nanospace by means of e...

  17. Resonance interaction energy between two accelerated identical atoms in a coaccelerated frame and the Unruh effect

    CERN Document Server

    Zhou, Wenting; Rizzuto, Lucia

    2016-01-01

    We investigate the resonance interaction energy between two uniformly accelerated identical atoms, interacting with the scalar field or the electromagnetic field in the vacuum state, in the reference frame coaccelerating with the atoms. We assume that one atom is excited and the other in the ground state, and that they are prepared in their correlated symmetric or antisymmetric state. Using perturbation theory, we separate, at the second order in the atom-field coupling, the contributions of vacuum fluctuations and radiation reaction field to the energy shift of the interacting system. We show that only the radiation reaction term contributes to the resonance interaction between the two atoms, while Unruh thermal fluctuations, related to the vacuum fluctuations contribution, do not affect the resonance interatomic interaction. We also show that the resonance interaction between two uniformly accelerated atoms, recently investigated in the comoving (locally inertial) frame, can be recovered in the coaccelerate...

    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

    2015-12-15

    The spectra of excited lithium-7 atoms prepared in a magneto-optical trap are studied using a UV laser. The laser diagnostics of the energy of Rydberg atoms is developed based on measurements of the change in resonance fluorescence intensity of ultracold atoms as the exciting UV radiation frequency passes through the Rydberg transition frequency. The energies of various nS configurations are obtained in a broad range of the principal quantum number n from 38 to 165. The values of the quantum defect and ionization energy obtained in experiments and predicted theoretically are discussed.

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

    International Nuclear Information System (INIS)

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

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

  3. Energy savings certificates 2011-2013 - Local Authorities. Knowledge for action

    International Nuclear Information System (INIS)

    Combating climate change and preserving our natural resources calls for a broad mobilization. Regional and local authorities and their public bodies are particularly concerned, as their own buildings and properties consume energy. These authorities are also essential drivers of local policies that can mobilize citizens and consumers within their territory. A number of tools and mechanisms are currently being implemented to meet these challenges, at the national and European levels. Among these, Energy Savings Certificates (ESCs) were introduced in France by the Energy Policy Law of 13 July 2005, with the aim of achieving energy savings in sectors of dispersed activity, mainly buildings, but also light industry, agriculture and transport. For local authorities this mechanism is an additional financial leverage tool that can be used to support their energy management projects. Under this scheme energy suppliers must promote energy-efficient investments, and thus are potential sources of financing for project owners. The Grenelle environmental conference forcefully reiterated the need to take action to renovate existing building stock. In order to achieve the ambitious goals that have been set, the financial mechanisms put into place, including the ESC scheme, must be amplified. Following the first conclusive test period (2006-2009), the ESC scheme is being ramped up during a second more ambitious three-year period that began on 1 January 2011. The present document is intended to inform local authorities of changes in the ESC scheme to be implemented for the second period covering 2011-2013. This guidance is divided into two parts: the first section describes the principles of the ESC scheme, and the second offers advice to local authorities that want to use this scheme for an energy management project. You will also find a practical information sheet listing all the steps to be taken to submit an ESC claim. In this document, for reasons of simplicity, the generic

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

    International Nuclear Information System (INIS)

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

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

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

    International Nuclear Information System (INIS)

    Circular-orbit accelerators, which until recently have merely been tools for fundamental research, are now finding ever increasing use in chemistry, biology, medicine and engineering. The demand to establish a cyclotron laboratory in egypt started at the beginning of seventies for scientific research and multidisciplinary applications. During 1988, the A.E.A. Egypt applied for assistance under the IAEA regular programme of the technical co-operation. In 1989, a pre-project mission was provided to appraise the proposal from the N.R.C. The main findings of the mission were that the infrastructure, both technical and manpower, was adequate for the transfer of cyclotron-based technology, and that the proposed programme would be beneficial to the scientific development of egypt. The IAEA input to the project is to make provision in 1991 and future years to purchase a compact cyclotron for light ions acceleration. The national input is that the A.E.A. is responsible for the design and construction of the building, allocating substantial funds to the project and providing related equipment, such as data acquisition systems, induced activity measuring equipment, and a solid-state laboratory. The contract for project was signed on september 27,1991, between the IAEA (supplier) techsnab export, (Russia) (manufacturer) and A.E.A., Egypt (end user). The main features of the cyclotron will be reviewed. The project is high amongst the priorities of the A.E.A. Egypt, and is expected to add an important facility to the infrastructure. The long-term aim is to exploit the considerable benefits for research, training and application in agriculture, ecological studies, industry, nuclear physics, and the production of radioisotopes. 3 tabs

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

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

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

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

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

    International Nuclear Information System (INIS)

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

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

  20. Hexagon's atom. History of the relation between France and the nuclear energy

    International Nuclear Information System (INIS)

    As soon as the end of the second World war, France, with the creation of the atomic energy commission (CEA), started a research program for the development of civil applications of nuclear energy, but also for the development of weapons. The come back of C. De Gaulle at the head of the country fostered the research efforts in both domains. Then, the election of G. Pompidou contributed to separate the military and civilian applications and led to the launching of the big French nuclear power program in March 1974. Nuclear contestation has shown a progressive development too, encouraged by the main accidents of Three Mile Island and more recently Tchernobyl. The debate has progressively moved with time from the safety of power plants towards the management of spent fuels. In this book, the author presents some particularities which are characteristic of France: the remnants of some kind of a 'scientism' inherited of the first half of the 20. century, the particular relations between 'scientists' and the republic, the policy of secret, the power of the senior officials corps and technocrats, the French taste for big works, the republican Jacobinism, the liabilities more easily given to State corps than to industrialists, and finally, on the opponents side, the search for the spectacular action to the detriment of efficiency. In this big fight, the know-how of nationalized companies, EdF and CEA, has been undeniable. The political power has very often taken refuge behind their competence but sometimes with a lack of democracy

    International Nuclear Information System (INIS)

    This collection of papers is primarily intended to give an insight into nuclear energy prospects in Brazil, but the lines of the discussion might well he helpful to those in other parts of the world who have to deal with similar problems. Some of the papers, which are selected from a series of lectures delivered in 1964 and 1965, have been translated in full, others abridged. In the bibliography, there are references to the periodicals in which the original papers appeared in Portuguese. The lectures were addressed to mixed audiences of mostly engineers, economists and other non-specialists in atomic energy. They were given at such places as the National Council for Economics; the Institute of Engineering (Sao Paulo); the Association of Engineers (Rio de Janeiro); and the Technical Board of the Federation of Commerce (Sao Paulo). Certain concepts overlap in some of the papers. The author has thought it advisable to keep the original texts instead of redrafting them, to avoid the risk of obscuring the points concerned

  2. 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.

    A ballistic atom pump is a system containing two reservoirs of neutral atoms or molecules and a junction connecting them containing a localized time-varying potential. Atoms move through the pump as independent particles. Under certain conditions, these pumps can create net transport of atoms from one reservoir to the other. While such systems are sometimes called "quantum pumps," they are also models of classical chaotic transport, and their quantum behavior cannot be understood without study of the corresponding classical behavior. Here we examine classically such a pump's effect on energy and temperature in the reservoirs, in addition to net particle transport. We show that the changes in particle number, of energy in each reservoir, and of temperature in each reservoir vary in unexpected ways as the incident particle energy is varied.

    2009-01-01

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

    Atomic- and void-species nanostructures are studied in As2S3 glass in unmodified and γ-modified states using a combination of conventional X-ray diffraction with respect to the first sharp diffraction peak, synchrotron-based high-energy X-ray diffraction and extended X-ray absorption fine structure spectroscopy. The experimental data are analyzed taking into account radiation-induced changes in the parameters of the first sharp diffraction peak (position, full width at half maximum, intensity), packing factor, structural disordering, atomic and void topology, coordination number and mean square deviation in bond length. The origin of the structural modification effect induced by γ-irradiation is explained in terms of coordination topological defects model. (authors)

  12. Anti-terror/non-proliferation efforts and South Korea's planning for atomic energy

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

    1993-01-01

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

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

    CERN Document Server

    Minissale, Marco; Dulieu, François

    2016-01-01

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

  1. On-line processing of searching scientific informations and literatures on atomic energy

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

  3. Summary history of domestic uranium procurement under US Atomic Energy Commission contracts. Final report

    International Nuclear Information System (INIS)

    During the period 1947 through 1970, the Atomic Energy Commission (AEC) fostered the rapid development and expansion of the domestic uranium mining and milling industry by providing a market for uranium. Some thirty-two mills were constructed during that period to produce U3O8 concentrates for sale to the AEC. In addition, there were various pilot plants, concentrators, upgraders, heap leach, and solution mining facilities that operated during the period. The purpose of this report is to compile a short narrative history of the AEC's uranium concentrate procurement program and to describe briefly each of the operations that produced uranium for sale to the AEC. Contractual arrangements are described and data are given on quantities of U3O8 purchased and prices paid. Similar data are included for V2O5, where applicable. Mill and other plant operating data were also compiled from old AEC records. These latter data were provided by the companies, as a contractual requirement, during the period of operation under AEC contracts. Additionally, an effort was made to determine the present status of each facility by reference to other recently published reports. No sites were visited nor were the individual reports reviewed by the companies, many of which no longer exist. The authors relied almost entirely on published information for descriptions of facilities and milling processes utilized

  5. A cancer mortality study in Bombay-based atomic energy community: 1975-1987

    International Nuclear Information System (INIS)

    Cancer deaths recorded by the centralized health services of the Department of Atomic Energy (DAE) among its employees and their families stationed in Bombay during 1975-1987 have been analysed. Expected number of deaths due to cancer in the study group has been estimated by using the age -sex -specific cancer death rates reported for Bombay resident population for the year 1983. The size of the database for the entire DAE community is about 702,000 person years and the number of cancer deaths observed in 154. Analysis has been done separately for employees and their families, individually for important groups of cancer sites such as respiratory organs, digestive organs, breast, genito-urinary organs and lymphatic and haematopoietic systems. The standardised mortality ratios are generally lower than 100, which may partly be due to the 'healthy worker effect' in the DAE community and partly because of its differences in the social class distribution and the concomitant differences in lifestyle with respect to the comparison group of Bombay city.

  6. The United States Atomic Energy Commission Programme of Nuclear Materials Management

    International Nuclear Information System (INIS)

    Nuclear materials management as conceived by the US Atomic Energy Commission is defined and its development traced from 1943 to the present time. The general programme is outlined and its principal features discussed. Emphasis is placed on administration of those portions of the USAEC programme which pertain to the development and maintenance of quantity data, the establishment of internal controls and the evaluation of performance. The current techniques whereby transfer data are recorded and processed within the USAEC are discussed in some detail, as are the techniques for presentation of material balance reports which periodically summarize the transactions and the results of operations. The techniques used by the USAEC to ascertain the effectiveness of the nuclear materials management programmes of its operating contractors are also discussed. In addition to material being held by contractors which operate USAEC-owned plants and laboratories, there are large quantities of special nuclear material held under a wide variety of financial and administrative arrangements, e.g. under lease, private ownership, under contract with the USAEC where the user is financially liable for losses, as well as those where the risk of losses is taken by the USAEC. This divergence of circumstances causes significant variation in the emphasis and approach used by the AEC and this variation is noted. A brief summary of unresolved problem areas concludes the presentation. (author)

  7. Results of the fifth three-dimensional dynamic atomic energy research benchmark problem calculation

    International Nuclear Information System (INIS)

    The pare gives a brief survey of the fifth three-dimensional dynamic atomic energy research benchmark calculation results received with the code DYN3D/ATHLET at NRI Rez. This benchmark was defined at the seventh AER Symposium. Its initiating event is a symmetrical break of the main steam header at the end of the first fuel cycle and hot shutdown conditions with one stuck out control rot group. The calculations were performed with the externally coupled codes ATHLET Mod.1.1 Cycle C and DYN3DH1.1/M3. The Kasseta library was used for the generation of reactor core neutronic parameters. The standard WWER-440/213 input deck of ATHLET code was adopted for benchmark purposes and for coupling with the code DYN3D. The first part of paper contains a brief characteristics of NPP input deck and reactor core model. The second part shows the time dependencies of important global, fuel assembly and loops parameters.(Author)

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

    International Nuclear Information System (INIS)

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

    Since the year 2010, the Energy Authority has the responsibility for the administration and coordination of work with Regulation (2009:893) on energy efficiency measures for government agencies. Under the regulation, the authorities choose to work with at least two of six actions. The authorities concerned by the Regulation shall annually report its energy use to the Energy Authority. Reporting must also show the results of the measures they have chosen to work with. This report shows the results of the authorities' reporting in February 2012, which covers the 2011 energy use. In addition, a deep analysis is made of 20 agencies to compare the results of their energy use 2010 and 2011. This has been to highlight if state governments can be seen as a pioneer in energy efficiency and if the authorities comply with the requirements of the Regulation. The results of the report show that the government's total energy consumption in 2011 amounts to 2 TWh. Many authorities have a functioning environmental management that energy work is a part of. The authorities also states that reporting contains flaws but that follow-up procedures evolve and improve. Shortcomings are due in part to data from many landlords based on certain assumptions.

    2015-07-09

    Five Steps to Implementing the PHA Energy Efficient Unit Turnover Package (ARIES, 2014) is a guide to prepare for the installation of energy efficient measures during a typical public housing authority unit turnover. While a PHA is cleaning, painting and readying a unit for a new resident, there is an opportunity to incorporate energy efficiency measures to further improve the unit's performance. The measures on the list are simple enough to be implemented by in-house maintenance personnel, inexpensive enough to be folded into operating expenses without needing capital budget, and fast enough to implement without substantially changing the number of days between occupancies, a critical factor for organizations where the demand for dwelling units far outweighs the supply. The following guide lays out a five step plan to implement the EE Unit Turnover Package in your PHA, from an initial Self-Assessment through to Package Implementation.

    International Nuclear Information System (INIS)

    The objective of the study is to evaluate the role of International Atomic Energy Agency in human resources development. The Agency is believed to be one of the specialized U N organizations aiming at peaceful applications of atomic energy in areas such as human health, animal health, agriculture, industry. Sudan joined the Agency in 1958 to make use of assistance provided to establish human development projects in the country through technical cooperation. Through this study, the role of research projects has been highlighted and the impact on human resources development and service enhancement is discussed. The annual reports from the Agency and the competent authority were the secondary sources. The primary source was personal interviews with national coordinators and director general of Sudan Atomic Energy Commission. The study concluded that the technical assistance from the Agency played a significant role in development through technology transfer especially in waste management, non-destructive testing, and human health. The role of Sudan Atomic Energy Commission in management of such projects is acknowledged.(Author)

    We report the features of an ion source based on two-color photoionization of a laser-cooled cesium beam outsourced from a pyramidal magneto-optical trap. The ion source operates in continuous or pulsed mode. At acceleration voltages below 300 V, it delivers some ten ions per bunch with a relative energy spread Δ Urms/U ≃0.032 , as measured through the retarding field-energy-analyzer approach. Space-charge effects are negligible thanks to the low ion density attained in the interaction volume. The performances of the ion beam in a configuration using focused laser beams are extrapolated on the basis of the experimental results. Calculations demonstrate that our low-energy and low-current ion beam can be attractive for the development of emerging technologies requiring the delivery of a small amount of charge, down to the single-ion level and its eventual focusing in the 10-nm range.

    1993-08-01

    Pulsed and steady-state photolysis experiments have been conducted to determine the rate coefficients for collisional deactivation of the spin-orbit excited state of atomic bromine, Br((sup 2)P(sub 1/2)). Pulsed lifetime studies for quenching by Br2 and CO2 established absolute rate coefficients at room temperature of k(sub Br2) = 1.2 +/- 0.1 x 10(exp-12) and k(sub CO2) = 1.5 +/0.2 x 10(exp-11) cu cm/molecule-s. Steady-state photolysis methods were used to determine the quenching rates for the rare gases, N2, 02, H2, D2, NO, NO2, N2O, SF6, CF4, CH4, CO, CO2, COS, SO2, H2S, HBr, HC1, and HI relative to that for Br2. Quenching rate temperature dependence was examined for Br2, CO2, N2O, HCl, COS, NO, and NO2 for temperatures from 300 to 420 K. Diffusion and three body effects were examined in order to determine the slowest relative quenching rate measurable by this experimental technique.

  20. Provisional legal protection in atomic energy law licensing procedures

    International Nuclear Information System (INIS)

    The duration of licensing procedures is to an increasing extent due to the provisional legal protection. The law (sec. 80 para. 5 Rules of the Procedure of Administrative Courts) leaves the question unanswered which requirements have to be met for the suspensive effect of a legal remedy against an administrative act which has been declared to be executed immediately to be reinstated. According to the author, the Courts can contribute substantially to minimizing the influence of the Courts. With respect to provisional legal protection, the Courts should on principle avoid a minute investigation of the lawfulness of licences which have been declared to be executed immediately. It is sufficient for the investigation to be plausible. In that case, the Courts fulfill their constitutional task according to article 19 para. 4 Constitutional Law and at the same time provide for speedy decision. (orig./HSCH)

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

    International Nuclear Information System (INIS)

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

    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.

    International Nuclear Information System (INIS)

    Since 1995, the Peruvian Institute of Nuclear Energy (IPEN) supported by the International Atomic Energy Agency (IAEA), has promoted tissue banking activity in the country, in order to provide population with safe radiation sterilized tissue grafts, principally for the treatment of severe lesions due to burnt or trauma. Through 04 technical cooperation projects, specific achievements were obtained: 01 tissue bank, 'Rosa Guerzoni Chambergo' (BTRGC) located at the Instituto de Salud del Nino (ISN), and counterpart of the projects, was implemented and started proper functioning. Between 1998 and 2005, 26152 radiation sterilized tissue grafts were produced and used to save or improve live quality of more than 2234 patients. Staff of the 03 Tissue Banks of the capital have been trained through expert missions, international and national courses. Technical reports, normative documents on production, sterilization and public awareness were elaborated, and will be useful complete national normative on tissue banking. Works presented at international events were also published. Clearly, were identified the final users of tissue banking technology and a network was conformed. On the other hand, the development of this activity permitted an adequate response to the requirement of grafts for the treatment of victims of the Great Fire of Mesa Redonda aroused in December 2001, radiation sterilization proved then, to be a reliable and secure method for providing safe grafts. Finally, IPEN successfully has adapted and transferred tissue banking technology and now has the challenge to promote decentralization of the activity as well as the acquisition of advanced technology on tissue banking of cells, biomaterials and radiation, in order to continuing innovation and technology transfer in this field for the benefit of Peruvian population.

    Low energy external Bremsstrahlung (EB) photons were used to estimate the K shell photoelectric parameters; the K shell photoelectric cross section at the K edge, the K shell binding energy, the K shell jump ratio, the K shell jump factors, the Davisson-Kirchner ratio and the K shell oscillator strength for dysprosium (Dy), ytterbium (Yb) and tungsten (W) atoms. The EB photons are produced in the nickel (Ni) target by using the beta particles from a weak beta source of {sup 90}Sr-{sup 90}Y. These photons are made to fall on these elemental targets of our interest and the transmitted spectrum is measured using GMX 10P HPGe detector coupled to an 8K multichannel analyzer. The sharp decrease at the K edge in the measured spectrum is used to determine the K shell photoelectric parameters of these elements. The experimental results are in good agreement with the theoretical values. (authors)

    2004-01-01

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

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

    Science.gov (United States)

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

    2016-09-01

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

  16. New approaches to the disclosure of atomic energy activities

    International Nuclear Information System (INIS)

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

  17. High energy-intensity atomic oxygen beam source for low earth orbit materials degradation studies

    International Nuclear Information System (INIS)

    A high intensity (1019O-atoms/s-sr) high energy (5 eV) source of oxygen atoms has been developed that produces a total fluence of 1022 O-atoms/cm2 in less than 100 hours of continuous operation at a distance of 15 cm from the source. The source employs a CW CO2 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/O2 mixtures. Visible and infrared photon flux levels of 1 watt/cm2 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 (H2O, NO, CO2). 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

  18. Atomic energy in the United States in 1992

    International Nuclear Information System (INIS)

    The use of energy may be constrained by a growing national consensus that we must choose; future courses that minimize adverse effect on public health, public safety, and the environment. It is believed nuclear power will be able to meet this challenge - more adequately than most fossil fuels. Thus it follows that the growth of nuclear power will be fostered by this trend. The United States today has contractual commitments of about 150 power plants with total capacity of about 130 million kilowatts electrical. When all of these plants are on line, by about 1980, that capacity will be equal to about 35% of our present electrical generating capacity. Of these commitments, 95% are for light water reactors - 62% for pressurized water and 33% for boiling water. The remaining 5% are high- temperature gas-cooled reactors. In this period of rapid expansion we are placing heavy emphasis on programmes to achieve higher levels of standardization, with the objective of improvements in safety, reliability and economics. Standardization will also shorten licensing reviews, provide for efficiency of labour and reduce maintenance problems. Meanwhile, improved technology in heat rejection techniques such as dry cooling will help to minimize the environmental problems, in addition, methods may be introduced to use rejected heat for beneficial purposes, such as food production in agriculture and aquaculture, as well as urban and industrial applications. Also during this period, biological research can be expected to result in continued progress toward identifying and understanding the effects of energy generation on man and his environment. With this increased knowledge, we will be better able to make wise decisions regarding the most effective use of all energy sources. The next major development step is the breeder reactor, which will achieve maximum utilization of fission fuels

  1. Development of Air Sampling Technology by the Atomic Energy Research Establishment, Harwell

    International Nuclear Information System (INIS)

    For many years the Health Physics and Medical Division of the Atomic Energy Research Establishment, Harwell, has pursued a vigorous programme of investigation and development in the field of air-sampling technology. The programme has made important contributions to the development of sampling media, the design of sampling equipment, the characterization of environmental airborne contamination and the interpretation of air-sampling data in terms of personal exposure. These developments form the basis for the present operational and research programmes in this field in the United Kingdom Atomic Energy Authority (U.K.A.E.A). . This paper, which summarizes the advances made in the Harwell laboratories in the above fields, is divided into three sections: 1. Sampling techniques. The development and characterization of glass-fibre filter papers (Stevens and Hounam) with improved surface collection properties has simplified counting procedures and has made ' possible detailed autoradiographic examination of the dust collected. The problem of energy degradation of alpha radiation by absorption in particles and paper has been studied (Stevens and Toureau). Development of charcoal-impregnated papers (Stevens and Hounam) has facilitated the detection and measurement of airborne contamination by iodine vapour. The combination of these papers with granular characoal in the May Pack (May) has given a sampling device which is now in common use for the determination and characterization of atmospheric iodine contamination. The concept and development of the personal air sampler (Sherwood and Greenhalgh) led to a better appreciation of the uncertainties of conventional air sampling and to the first quantitative demonstration of the problems of interpreting air samples in terms of personal inhalation exposure. Work on the design of a size selective head for the personal air sampler has not yet resolved the difficulties. The drawbacks of the cascade impactor as a continuous size

    International Nuclear Information System (INIS)

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

  7. Intermediate-energy electron scattering by atomic hydrogen

    International Nuclear Information System (INIS)

    Both elastic and inelastic scattering were studied in the framework of the close-coupling equations. The models were formulated in terms of integral equations for T-matrices in momentum space. Using this representation it was possible to study the effects of approximations to the multiple-scattering series in a direct manner. For elastic scattering it was established that the approximations made in using a second-order optical-potential formalism gave rise to at most 10% error in the reaction mechanism at 50 eV and considerably less at higher energies. Inelastic 1s-2s and 1s-2p scattering was analysed in terms of a three-state close-coupling model and approximations to it. The marked sensitivity of the angular correlation parameters to approximation was shown. It was suggested that detailed agreement between theory and experiment requires a close-coupling model containing several more channels

    CERN Document Server

    2016-01-01

    We study the hydrogen atom eigenstate energy and wave function in the Rindler space. The probability distribution is tilted because the electric field of the nucleus is no longer spherically symmetric. The hydrogen atom therefore cannot be treated exactly in the same way as what it is in an inertial frame. We also find that if the external force accelerates only the nucleus and then the nucleus accelerates its surrounding electrons through electromagnetic force, the electrons can tunnel through the local energy gap and split the hydrogen atom into an ion. This is similar to what one expects from the Stark effect. However, the critical acceleration is about $3\\times 10^{22} m/s^2$. It is well beyond the gravitational acceleration on a regular star surface.

  10. Building America Case Study: Philadelphia Housing Authority Energy-Efficiency Turnover Protocols, Philadelphia, Pennsylvania

    Energy Technology Data Exchange (ETDEWEB)

    2016-02-01

    Over one million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with four PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost-effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing, and measures that improve equipment efficiency. ARIES documented implementation in 18 housing units. Reductions in average air leakage were 16 percent and duct leakage reductions averaged 23 percent. Total source energy consumption savings due to implemented measures was estimated at 3-10 percent based on BEopt modeling with a simple payback of 1.6 to 2.5 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

    2000-01-01

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

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

  11. Wholesomeness and Public Health Research in the United States Atomic Energy Commission Food Irradiation Programme

    International Nuclear Information System (INIS)

    To assess the biological safety of foods which are of interest to the Atomic Energy Commission's irradiated food program, studies have been sponsored by the Commission's Division of Biology and Medicine since 1961. Wholesomeness, microbiological and biochemical studies have been undertaken with a view to complementing data derived from developmental, economic and technological research studies sponsored by the Commission's Division of Isotopes Development. When these aspects appear feasible for specific low-dose irradiated foods, studies are initiated to provide relevant data required by the United States Food and Drug Administration before final judgements can be made on petitions for unlimited human consumption. Toxicity studies on several species of animals which are fed diets containing up to 35° (dry solids basis) of the irradiated food in question have been included in this program. Investigations of two years duration on animals (rats, dogs and chickens) provide data concerning food consumption, growth rate, enzyme systems, haematology, gross pathology and histopathology. Shorter-term studies of a confirmatory nature on two animal species (rat and dog) are employed in certain cases when the irradiated food in question is sufficiently related to foods which have previously undergone long-term toxicity studies. Results to date of chronic toxicity studies on soft-shell clams and subacute toxicity studies on strawberries, apples, pears, sweet cherries, apricots, plums and onions are discussed. Microbiological studies have been concentrated primarily on potentially pathogenic organisms. Studies have been in progress to evaluate carefully the conditions governing radiation and heat resistance, sporulation, outgrowth and toxin production of Clostridium botulinum Type E. The natural incidence of Type E organisms in certain marine products and ocean environments is being investigated. Findings in the microbiological studies are discussed. Studies to date have

  12. Environmental Radioactivity Studies Within The Vietnam Atomic Energy Institute During The Time Period 1980 - 2010

    International Nuclear Information System (INIS)

    This report summarizes results of the monitoring activities for natural and anthropogenic radioactivity in the environment such as in surface soil, in surface and groundwater, in the atmosphere and food of Viet Nam that have been conducted by the staff of the Vietnam Atomic Energy Institute (VAEI) since the first day of its foundation. Among natural radionuclide, uranium/radium, thorium, potassium-40 in surface soils and 222Rn in the atmosphere are of particular interest for estimating the annual effective dose resulted from gamma radiation and inhalation to the public. The total annual effective dose (outdoor and indoor dose) from gamma radiation of natural radioactivity (U, Th, 40K) in surface soil to the public of all the 63 provinces over Viet Nam was estimated as high as 0.54 mSv that is in 10% higher than those reported in the UN SCEAR-2000. The annual effective dose due to inhalation with the air containing 222Rn to the habitant in the Ha Noi city was found to be as high as 1.13 mSv that is in the range of the dose reported for the Asian region. The anthropogenic radionuclides under the monitoring are 90Sr, 137Cs, and 239+240Pu originated from nuclear weapon tests during the 1950-1960. Concentration of the anthropogenic radionuclide in surface soil gives an idea about the fall-out inventory of the radio-isotopes from the nuclear explosion in the past. This information would be necessary for the Environmental Impact Assessment for the Nuclear Power Construction Project in Viet Nam. The results of environmental radioactivity monitoring activities of the VAEI has been composed in twelve scientific papers published in numerous International Scientific Journals like J. Environ. Radioact. and Radiat. Prot. Dosim. Two books entitled: Radioactivity in the Environment and Radioactivity Measurement Applied in the Environmental Researches has been drafted and submitted to the Science and Technique Publisher for printing out soon.

  13. A clinical audit programme for diagnostic radiology: The Approach adopted by the international atomic energy agency

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency (IAEA) has a mandate to assist member states in areas of human health and particularly in the use of radiation for diagnosis and treatment. Clinical audit is seen as an essential tool to assist in assuring the quality of radiation medicine, particularly in the instance of multidisciplinary audit of diagnostic radiology. Consequently, an external clinical audit programme has been developed by the IAEA to examine the structure and processes existent at a clinical site, with the basic objectives of: (1) improvement in the quality of patient care; (2) promotion of the effective use of resources; (3) enhancement of the provision and organisation of clinical services; (4) further professional education and training. These objectives apply in four general areas of service delivery, namely quality management and infrastructure, patient procedures, technical procedures and education, training and research. In the IAEA approach, the audit process is initiated by a request from the centre seeking the audit. A three-member team, comprising a radiologist, medical physicist and radiographer, subsequently undertakes a 5-d audit visit to the clinical site to perform the audit and write the formal audit report. Preparation for the audit visit is crucial and involves the local clinical centre completing a form, which provides the audit team with information on the clinical centre. While all main aspects of clinical structure and process are examined, particular attention is paid to radiation-related activities as described in the relevant documents such as the IAEA Basic Safety Standards, the Code of Practice for Dosimetry in Diagnostic Radiology and related equipment and quality assurance documentation. It should be stressed, however, that the clinical audit does not have any regulatory function. The main purpose of the IAEA approach to clinical audit is one of promoting quality improvement and learning. This paper describes the background to

  14. Effect of external energy on atomic, crystalline and powder characteristics of antimony and bismuth powders

    Indian Academy of Sciences (India)

    2009-10-01

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

    2013-01-01

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

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

    International Nuclear Information System (INIS)

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

    Science.gov (United States)

    Creager, Angela N H

    2006-01-01

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

  20. Antiprotonic-hydrogen atoms

    International Nuclear Information System (INIS)

    Experimental studies of antiprotonic-hydrogen atoms have recently made great progress following the commissioning of the low energy antiproton facility (LEAR) at CERN in 1983. At the same time our understanding of the atomic cascade has increased considerably through measurements of the X-ray spectra. The life history of the p-bar-p atom is considered in some detail, from the initial capture of the antiproton when stopping in hydrogen, through the atomic cascade with the emission of X-rays, to the final antiproton annihilation and production of mesons. The experiments carried out at LEAR are described and the results compared with atomic cascade calculations and predictions of strong interaction effects. (author)
