    International Nuclear Information System (INIS)

    Kuesters, H.

    1982-01-01

    The Nuclear Research Center Karlsruhe (KfK) is funded to 90% by the Federal Republic of Germany and to 10% by the State of Baden-Wuerttemberg. Since its foundation in 1956 the main objective of the Center is research and development (R and D) in the aera of the nuclear technology and about 2/3 of the research capacity is now devoted to this field. Since 1960 a major activity of KfK is R and D work for the design of fast breeder reactors, including material research, physics, and safety investigations; a prototype of 300 MWe is under construction now in the lower Rhine Valley. For enrichment of 235 U fissile material KfK developed the separation nozzle process; its technical application is realized within an international contract between the Federal Republic of Germany and Brazil. Within the frame of the European Programme on fusion technology KfK develops and tests superconducting magnets for toroidal fusion systems; a smaller activity deals with research on inertial confinement fusion. A broad research programme is carried through for safety investigations of nuclear installations, especially for PWRs; this activity is supplemented by research and development in the field of nuclear materials' safeguards. Development of fast reactors has to initiate research for the reprocessing of spent fuel and waste disposal. In the pilot plant WAK spent fuel from LKWs is reprocessed; research especially tries e.g. to improve the PUREX-process by electrochemical means, vitrification of high active waste is another main activity. First studies are being performed now to clarify the necessary development for reprocessing fast reactor fuel. About 1/3 of the research capacity of KfK deals with fundamental research in nuclear physics, solid state physics, biology and studies on the impact of technology on environment. Promising new technologies as e.g. the replacement of gasoline by hydrogen cells as vehicle propulsion are investigated. (orig.)

    International Nuclear Information System (INIS)

    Harde, R.

    1981-01-01

    The Karlsruhe Nuclear Research Center was founded on July 19, 1956. The initial company, in which the Federal Republic of Germany held a 30% interest, the State of Baden-Wuerttemberg 20%, and German industry 50%, was founded mainly for the purposes of building and operating a German-designed research reactor. In 1959, the Gesellschaft fuer Kernforschung mbH was founded for execution of the research and development activities, in which the Federal Republic of Germany held 75%, the State of Baden-Wuerttemberg 25% of the shares. The two companies were merged in 1963, after industry had donated its holdings in the initial company to the new company. In 1972, the financial holdings of the Federal Government were raised to 90%. On January 1, 1978, the company was named Kernforschungszentrum Karlsruhe GmbH (KfK). Over the past 25 years, KfK has received approx. DM 7 billion out of public funds. Important milestones in the development of nuclear technology in the Federal Republic contributed by KfK include the development of the fast breeder line and responsibility for construction of the first German fast breeder reactor, KNK; development of reprocessing technologies and responsibility for construction of the first German reprocessing plant, WAK; development of a uranium enrichment technique (separation nozzle method); important contributions to reactor safety, fusion research, and training in nuclear technology.

    2001-01-01

    The case of Forschungszentrum Karlsruhe is presented which had to transform from a centre devoted to nuclear power R and D to one in which this activity is allocated only 20% of the resources. A large number of operating nuclear power reactors coupled with the Government decision to phase out nuclear power is causing serious concerns regarding the availability of human resources for meeting the long term needs of nuclear facilities. The Energy Division of the research centre currently focuses mainly on safety research and on nuclear fusion. Another Division of the centre has nuclear facility decommissioning as one of the programmes. Independent research in areas of essential need for nuclear facilities must be carried out to maintain know how. (author)

    Baehr, W; Hempelmann, W; Krause, H

    1976-06-01

    In 1971 a large incineration plant started operation in the Nuclear Research Center Karlsruhe. This plant is serving for routine incineration of up to 100 kg of combustible radioactive solids or 40 l of contaminated organic liquids and oils per hour. A dry off-gas cleaning system has been developed for this installation in which the fumes are cleaned by ceramic filter candles. After passing the filtering system and cooling, the off-gas is discharged directly through a stack. The activity concentration in the off-gas is measured by a continuous monitoring system. The ashes arising from the incineration are mixed with cement grout and filled into 200 l-drums. By this way approximately one drum of fixed ashes results from 100 drums of combustible wastes. During the first four years of operation, more than 4,000 m/sup 3/ of combustible solids and about 60 m/sup 3/ organic solvents have been incinerated in the plant. The operating experiences are presented.

    1983-07-01

    Evaluation of the data from the personnel dosimetry of the staff monitored from 1969 until 1981 at the Karlsruhe Nuclear Research Center (Kernforschungszentrum Karlsruhe GmbH) gives a total external dose of 6,335 rem including natural radiaiton background. The occupational exposure of the radiation workers within this period comes to 3,076 rem, which gives an average annual external occupational exposure of 0.14 rem. In 1,832 cases an annual dose between 0.5 and 1.5 rem per year and in 353 cases a dose of more than 1.5 rem per year have been measured. The highest value, measured in 1972, amounted to 6.8 rem. During the period from 1969 until 1981 more than 34,000 incorporation measurements were performed with the whole body counter and the lung counter, 1,963 cases with positive findings. In 96% of the cases the values of incorporated activity were inferior to 1% - in 70% even inferior to 0.1% - of the maximum permissible body burden values of ICRP 2. Only 5 cases exceeded these values. (orig.) [de

  16. Karlsruhe Nuclear Research Center, Institute for Meteorology and Climate Research. Progress report on research and development work in 1993

    International Nuclear Information System (INIS)

    1994-03-01

    The Institute for Meteorology and Climate Research is operated by Karlsruhe Nuclear Research Centre in cooperation with Karlsruhe University. It investigates mesoscale and global atmospheric processes. Work on mesoscale processes focuses on interactions between atmosphere, soil and vegetation via the exchange of momentum, energy, water, and materials. Another field of primary interest are the flow processes and turbulent exchange processes in the lower troposphere. Parallel to the experiments, numerical simulation models for describing and predicting mesospheric climate-relevant processes and atmospheric exchange processes were used and improved upon. For remote processing of atmospheric parameters, a satellite-based data processing system was used for recording land surface parameters and vertical profiles and meteorological variables that are applicable for climatological studies and for the validation of numerical models. For recording and interpretation of the spatial and time-dependent distribution of trace elements, measuring instruments in the field of air chemistry were newly developed or improved upon, especially with a view towards high time resolution of the measured data. Ozone research is a key issue of the remote measurements. Contributions were made primarily in the framework of international research programmes (e.g. EASOE) on the degradation of the atmospheric ozone layer in the higher latitudes of the northern hemisphere.

    The research activities in the light water reactor (LWR) severe accidents domain at Karlsruhe Institute of Technology (KIT) are concentrated on the in- and ex-vessel core melt behavior. The overall objective is to investigate the core melt scenarios from the beginning of core degradation to melt formation and relocation in the vessel, possible melt dispersion to the reactor cavity and to the containment, corium concrete interaction and corium coolability in the reactor cavity, and hydrogen behaviour in reactor systems. The results of the experiments contribute to a better understanding of the core melt sequences and thus improve safety of existing and, in the long-term, of future reactors by severe accident mitigation measures and by safety installations where required. This overview paper describes the experimental facilities used at KIT for severe accident research and gives an overview of the main directions and objectives of the R&D work. (author)

    The planned ITER plant needs plasma heating powers of approx. 70-150 MW. Work performed at the Karlsruhe Research Center under this heading mainly comprises the development of microwave oscillators (gyrotrons) and their use for an electron cyclotron resonance heating system and for non-inductive plasma current operation. The plasma, which is approx. 100 million C hot, is confined in a 'magnetic cage' so as to avoid any contact with the wall structures of the vacuum vessel. Building up a magnetic field of this magnitude requires field strengths of at least 2-5 tesla in the plasma; field strengths of 11-13 tesla at the magnet coils are required for future fusion plants, such as ITER. Consequently, the development of the required future superconducting magnet coils enjoys high priority. The blanket, i.e. the enclosure around the combustion chamber of a fusion reactor, plays a major role in the design of a future fusion power plant. Blanket concepts meeting technical requirements are being developed and studied. A blanket must meet three requirements: It must convert the neutron energy into heat, breed the tritium fuel by nuclear reactions, and shield the magnets from neutron and gamma radiations. The fuel cycle of fusion reactors is determined by the gaseous phase of the two hydrogen isotopes, deuterium and tritium. In general, hydrogen handling technologies have been developed to a high level, but can be transferred to the handling of deuterium and radioactive tritium only to a very limited extent. Consequently, the necessary development work is carried out. The state of the plasma, also with respect to its purity, is a factor of special importance, as impurities will cause the plasma to dissolve and thus the fusion reaction to break down. Primary vacuum pumps, another area of activity of the Karlsruhe Research Center, first must evacuate the reactor vessel and then, during operation, maintain the necessary atmosphere. (orig.) [de

    Full text of publication follows. The work on minor actinide (MA) partitioning carried out at Karlsruhe and Juelich is integrated in the EC FP6 programme, EUROPART. Studies include the DIAMEX process (co-extraction of MA and lanthanides from PUREX raffinate) and the SANEX process (separation of MA from lanthanides). Aspects ranging from developing and improving highly selective and efficient extraction reagents, to fundamental structural studies, to process development and testing are covered. SANEX is a challenge in separation chemistry because of the chemical similarity of trivalent actinides and lanthanides. The extracting agents 2,6-di(5,6-di-propyl-1,2,4-triazine-3-yl)pyridine (n-Pr-BTP), developed at Karlsruhe, and the synergetic mixture of di(chloro-phenyl)di-thio-phosphinic acid (R2PSSH) with tri-n-octyl-phosphine oxide (TOPO), developed at Juelich, are considered a breakthrough because of their high separation efficiency in acidic systems. Separation factors for americium over lanthanides of more than 30 (R2PSSH+TOPO) and 130 (n-Pr-BTP) are achieved. To gain understanding of these selectivities, comparative investigations on the structures of curium and europium complexed with these SANEX ligands were performed at Karlsruhe. Extended X-ray absorption fine structure (EXAFS) analysis revealed distinct structural differences between curium and europium complexed with R2PSSH + TOPO, though no such differences were found for n-Pr-BTP. These investigations were therefore complemented by time-resolved laser fluorescence spectroscopic investigations (TRLFS), showing complex stabilities and speciation to differ between n-Pr-BTP complexes of curium and europium. Kinetics of mass transfer was studied for both R2PSSH+TOPO and n-Pr-BTP systems. For the R2PSSH + TOPO system, diffusion was identified to control extraction rates. For the n-Pr-BTP system, a slow chemical reaction was identified as the rate-controlling process. These results were implemented into computer

    Under an IAEA sponsored measurement program the tritium level is investigated in the immediate and more distant environment of the Karlsruhe Nuclear Research Center. The tritium concentration in precipitations, surface, ground and drinking water is measured within a long-term program. In addition, relationships existing between the tritium concentration of plants and the concentrations of ground water, precipitation, soil and air humidities are investigated at three points in special series of measurement. A summary report is presented on recent measured results. According to these results, the annual mean values for precipitations and surface water tend to rise. In 1975 the annual mean values amounted to 0.89 nCi/l of tritium concentration in precipitations in the more distant environment of the Nuclear Research Center and to 0.68 nCi/l in the Rhine river. In plants tritium concentrations were observed which correspond to that measured in the humidity of the air. The radiation exposure of people living in large towns is calculated to be about 50 μrem/a in the region monitored, due to the presence of tritium in the drinking water. A little group of the population takes up as much as 110 μrem/a. (orig.) [de

    In 1971 a large incineration plant started operation in the Nuclear Research Center Karlsruhe. This plant is serving for routine incineration of up to 100 kg of combustible radioactive solids or 40 l of contaminated organic liquids and oils per hour. A dry off-gas cleaning system has been developed for this installation in which the flue gases are cleaned by ceramic filter candles. After passing the filtering system and cooling the off-gas is discharged directly through a stack. The activity concentration in the off-gas is measured by a continuous monitoring system. The ashes arising from the incineration are mixed with cement grout and filled into 200 ldrums. By this way approximately one drum of fixed ashes results from 100 drums of combustible wastes. During the first four years of operation, more than 4,000 m 3 of combustible solids and about 60 m 3 organic solvents have been incinerated in the plant. The operating experiences are presented.

    The LACOMERA project at the Forschungszentrum Karlsruhe, Germany, is a 4 year action within the 5th Framework Programme of the EU which started in September 2002. Overall objective of the project is to offer research institutions from the EU member countries and associated states access to four large-scale experimental facilities QUENCH, LIVE, DISCO, and COMET. These facilities can be used to investigate core melt scenarios from the beginning of core degradation to melt formation and relocation in the vessel, possible melt dispersion to the reactor cavity, and finally corium concrete interaction and corium coolability in the reactor cavity. The paper summarises the main results obtained in the following experiments performed up to now. QUENCH-L1: Impact of air ingression on core degradation. The test provides unique data for the investigation of air ingress phenomenology in conditions as representative of a spent fuel pool accident as possible; QUENCH-L2: Boil-off of a flooded bundle. The test is of a generic interest for all reactor types, provided a link between the severe accident and design basis areas, and would deliver oxidation and thermal hydraulic data at high temperatures. DISCO-L1: Thermal hydraulic behaviour of the corium melt dispersion neglecting the chemical effects such as hydrogen generation and combustion. COMET-L1: Long-term 2D concrete ablation in a siliceous concrete cavity at intermediate decay heat power level with a top flooding phase after a phase of dry concrete erosion. COMET-L2: Investigation of long-term melt-concrete interaction of metallic corium in a cylindrical siliceous concrete cavity under dry conditions with decay heat simulation of intermediate power during the first test phase, and subsequently at reduced power during the second test phase.

    A procedure was developed to measure Pu-241 by liquid scintillation counting. Sample preparation was performed by electroplating of plutonium on stainless steel planchets. To correct the selfabsorption, the linear dependence of counting efficiency in the liquid scintillation counter from the resolution in the alpha spectrometer was used. Pu-238, Pu-239+240 and Pu-241 were measured in the liquid effluents of the Karlsruhe Nuclear Research Center (KfK). The concentrations in monthly mixed samples ranged from 0.07 until 46 nCi Pu-238/m 3 , from 0.13 until 2.1 nCi Pu-239+240/m 3 and from 25 until 190 nCi Pu-241/m 3 . Between 5.4% and 41% of the plutonium content of the KfK waste water are released to the River Old Rhine. The values for the activity ratio Pu-238/Pu-239+240 are between 0.39 and 1.1 and for Pu-241/Pu-239+240 are between 11 and 300. The mean value for Pu-241/Pu-239+240 is 61. The dose exposure of the environmental population of the Karlsruhe Nuclear Research Center caused by released Pu-241 is negligible low. (orig./HP) [de

    The Karlsruhe Research Center is Germany's largest multidisciplinary research establishment in the fields of natural sciences and technology. In its relatively short period of existence, the Research Center has experienced vivid evolution and modification of original research goals, and even a profound change of the major tasks and goals laid down at the time of its foundation, which most obviously expresses itself in the change of name from Nuclear Research Center into Research Center, effective since January 1995. The wealth of important material accumulated in the archives of the Center throughout the almost 40 years of existence is a treasure for the historian and offered the tempting and useful task to process the material into a historical survey offering the many facettes of the history: in the end, the result combines an important piece of history of technology with the history of the Land of Baden-Wuerttemberg, the region, and the neighbouring city of Karlsruhe. In addition, the publication in hand also offers insight into the sociological aspects of the research work performed in the Center, and the interactive impetus of research and development in the interest of society at large.

  18. Research on transmutation and accelerator-driven systems at the Forschungszentrum Karlsruhe

    International Nuclear Information System (INIS)

    Knebel, J.U.; Heusener, G.

    2000-01-01

    Transmutation is considered a promising technology worldwide for significantly reducing the amount and, thereby, the long-term radiotoxicity of high active waste (HAW) produced by the operation of nuclear power plants such as light water reactors (LWR). The maximum reduction of radiotoxicity could be by a factor of about 100. Transmutation is thus an alternative to the direct deposition of large volumes of highly radioactive waste. Transmutation presents the possibility of closing the fuel cycle including the minor actinides. Plutonium, minor actinides and long-lived fission products can be transmuted in a so called Accelerator Driven Sub-critical System (ADS), which consists of an accelerator, a target module and a subcritical blanket. This paper describes the work performed at Forschungszentrum Karlsruhe which is critically evaluating an ADS mainly with respect to its potential for transmuting minor actinides, to its feasibility and to safety aspects. The work is being done in the area of core design, neutronics, safety, system analyses, materials and corrosion. (orig.) [de

    Schuettelkopf, H.; Pimpl, M.

    1986-01-01

    The plutonium concentrations in the surroundings of the Karlsruhe Nuclear Research Centre (KfK) are in the range of variation of the global plutonium contamination caused by fallout of atmospheric nuclear tests. Exclusively in the sediments of the Old River Rhine, which serves as main canal for the liquid effluents, higher plutonium concentrations could be detected. The dose exposure of the population living in the environment of the KfK caused by the measured plutonium concentrations is negligible low. From the Karlsruhe Reprocessing Plant (WAK) and the facilities needed to decontaminate radioactive wastes 0.48 GBq (13 mCi) plutonium alpha activity has been emitted within 11 years of operation until 1982 - 1/3 with the liquid effluents and 2/3 with the exhaust air. Following the pathway with the exhaust air, plutonium concentrations in the environment of the Karlsruhe Reprocessing Plant were measured in groundlevel air, in soil, in plants, in food and in animal tissues. Radioecological parameters like dispersion factors, deposition velocities, migration velocities in soil and transfer soil-to-plant were investigated. Following the pathway with the liquid effluents, plutonium concentrations were measured in surface waters, sediments, water plants, plankton and animals. Dilution and sedimentation behaviour were studied as well as the transfer water-to-plant and water-to-animals. (orig.) [de

    It will be first described how the system of financing has progressed since the establishment of the Center. A distinction will be made between four different financing models in succession. The presentation of these financing models will be accompanied by a description of building up and development of the Center, mainly under financial aspects. The second part will show the development of accountancy and balance striking. Particular courses will be indicated which are typical of large research establishments funded by the government, thus providing the picture of an accountancy system specifically adapted to research establishments. It differs from classical business accounting by laying a bridge to the cameralistic accountancy of public authorities. Besides, the organization and tools of KfK cost accounting will be described. Finally, the third part will present statistical time series (1956 to 1979) including both the annual balances, annual expenditures and some average numbers (per capita numbers). These time series will be supplemented each by short comments. (orig./HP) [de

    1978-08-01

    Within the framework of the Fast Breeder Project various institutes of the KarIsruhe Nuclear Research Center operate sodium loops for corrosion studies and component tests under sodium. The operation of these loops has led to extensive experience in cleaning sodium-wetted components. This experience relates to the alcohol method, the removal of sodium by melting, storage in air, and to cleaning by means of steam. Deposition samples from radioactive sodium loops were used for decontamination experiments employing various decontaminating agents. The department concerned with the treatment of radioactive waste studied the use of molten salts and paste type cleansers for components unsuitable for mechanical decontamination, primarily with the objective to reduce the amount of radioactive waste.

    Elbel, H.

    1979-01-01

    Fuel pin modelling has been pursued at the Institute of Materials and Solid State Research (IMF) of the Karlsruhe Nuclear Research Centre (KfK) with the main objective to provide a detailed quantitative analysis of the fuel pin behaviour in a LMFBR under normal and off-normal operation conditions. The computer programs and models developed at the IMF serve the purpose to aid effectively in the development of an optimized fuel pin concept for a LMFBR. What extent of clad deformation can be tolerated without running into clad failure? What is the influence of neutron dose, temperature, corrosion attack, arid cyclic forces on the state of the clad? What may be the reasons for clad failure? In answering these questions computer programs can play an important role. The activities at the IMF in the field of fuel pin modelling cover the following topics: development of computer programs and models; validation of these programs and models, application to the design of fuel pins for irradiation experiments; assistance in the evaluation of operation data and post- irradiation results, and parametric studies on the influence of design parameters, operation conditions and certain material phenomena on the in-pile behaviour of the fuel pin

  20. Establishing a Research Information System as Part of an Integrated Approach to Information Management: Best Practice at the Karlsruhe Institute of Technology (KIT

    Directory of Open Access Journals (Sweden)

    Frank Scholze

    2012-01-01

    Full Text Available The Karlsruhe Institute of Technology (KIT is one of the largest research and higher education organisations in the world focusing on engineering and natural sciences. At present KIT, under the chairmanship of its executive board, is installing an extensive current research information system (CRIS covering all institutes and facilities of the organisation. The assumption underlying the project is that a consistent overview of research performance has become fundamental for the international competitiveness of research institutions and is increasingly important for strategic decisions at the executive level. Ultimately, it also leads to better data and control in rankings at higher education assessments. The new research information system systematically maps all of KIT’s processes and instruments to obtain, connect, present and utilise the research metadata of active researchers. This reduces the documentation workload for researchers, for the executive level and central units such as the library, and at the same time allows for and facilitates an overall view and the aggregation and visualisation of research metadata. Our vision is to build a federally structured network of systems that gathers information on KIT’s publications, research competence, research projects, patents and technological offers by retrieving data from external and internal sources as well as directly from the researchers. The network facilitates linking and aggregating of data and provides unique identifiers for individual researchers and organizational units. With its consistent data model the research information system also fosters the organisational development of KIT, which was formed in 2009 by the merger of a university and a national research centre. The researchers and their activities are at the core of the research information system. The system substantially reduces their administrative burden in documenting project information and publications. Automatic

    1976-08-01

    The radiological impact by radioactive offgas and exhaust air on the environment of the Karlsruhe Nuclear Research Center (KNRC) is calculated every year and compared with the permissible equivalent doses. This report includes both the forecasted maximum doses from maximum releases scheduled for the year 1976 and the actual doses of 1975 based on the measured releases in 1975. According to the various irradiation mechanisms of the nuclides emitted, the following doses are indicated, each calculated for an adult person: whole body dose by γ-irradiation and tritium inhalation, skin dose by external β-irradiation, lung dose by aerosol inhalation, bone dose by plutonium inhalation, and effective integral dose. The maximum infant thyroid dose due to iodine ingestion via the pasture-cow-milk-pathway is also calculated. The respective maximum doses indicate that the dose limits of 30 mrem/a whole body dose (adult) and 90 mrem/a thyroid dose (Infant) which are to be observed by the KNRC since the year 1975 are not exceeded at any point, provided the emissions remain below the scheduled maximum level. The doses in 1975 were markedly below the dose limits mentioned above. This is even true when partial body and organ doses are integrated in an 'effective dose'. (orig.) [de

    Measurements and calculations of fundamental atomic collision and spectroscopic properties such as collision cross sections, reaction rates, transition probabilities etc. underpin the understanding and operation of many plasma and gas-discharge-based devices and phenomena, for example plasma processing and deposition. In almost all cases the complex series of reactions which sustains the discharge or plasma, or produces the reactive species of interest, has a precursor electron impact excitation, attachment, dissociation or ionisation event. These processes have been extensively studied in a wide range of atomic and molecular species and an impressive data base of collision cross sections and reaction rates now exists. However, most of these measurements are for collisions with stable atomic or molecular species which are initially in their ground electronic state. Relatively little information is available for scattering from excited states or for scattering from unstable molecular radicals. Examples of such species would be metastable excited rare gases, which are often used as buffer gases, or CF 2 radicals formed by electron impact dissociation in a CF 4 plasma processing discharge. We are interested in developing experimental techniques which will enable the quantitative study of such exotic atomic and molecular species. In this talk I would like to outline one such facility which is being used for studies of collisions with metastable He(2 3 S) atoms

    The Wiederaufarbeitungsanlage Karlsruhe (WAK) serves as a demonstration plant for the processing of highly-irradiated uranous oxide. The high active waste concentrates find interim storage at the WAK until they are solidified at a later stage. In contrast to this, the slightly- and the medium-active liquid wastes are transported to the decontamination facility of the Nuclear Research Centre Karlsruhe, where they are immediately processed. These liquid wastes contain about 1 per thousand of the activity inventary of the fuel elements processed. Monitoring of the radioactive waste water of the WAK is carried out by the Nuclear Research Centre's department radiation protection and safety. (orig.) [de

    After a Conceptual Design Activity (CDA) study on an International Fusion Material Irradiation Facility (IFMIF) has been launched under the auspices of the IEA, working groups and relevant tasks have been defined and agreed in an IEA-workshop that was held September 26-29 1994 at Karlsruhe. For the Test Cell System 11 tasks were identified which can be grouped into the three major fields neutronics, test matrix/users and test cell engineering. In order to discuss recently achieved results and to coordinate necessary activities for an effective design integration, a technical workshop on the Test Cell System was initiated. This workshop was organized on July 3-6 1995 by the Institute for Materials Research I at the Forschungszentrum Karlsruhe and attended by 20 specialists working in the fields neutronics, fusion materials R and D and test cell engineering in the European Union, Japan, and the United States of America. The presentations and discussions during this workshop have shown together with the elaborated lists of action items, that has been achieved in all three fields, and that from the future IFMIF experimental program for a number of materials a database covering widerspread loading conditions up to DEMO-reactor relevant end-of-life damage levels can be expected.

    An attempt was made to analyze the trends in the development of exotic-atom research on the basis of a recently compiled bibliography. The analysis of nearly 4000 publications demonstrated that: (1) exotic atoms are nuclear probes used in every field of physics, from the test of quantum electrodynamics (QED) to chemical physics, to materials sciences; (2) the role of nuclear and atomic physics in exotic atom research is decreasing (although it is still significant), while that of materials sciences and chemial physics is exponentially increasing; and (3) prior to 1980 most investigators were mainly interested in atoms with negative muons, while during the last few years the positive muon (μSR) studies have dominated exotic atom research

    2010-07-23

    The Atomic and Molecular Interactions Gordon Conferences is justifiably recognized for its broad scope, touching on areas ranging from fundamental gas phase and gas-condensed matter collision dynamics, to laser-molecule interactions, photophysics, and unimolecular decay processes. The meeting has traditionally involved scientists engaged in fundamental research in gas and condensed phases and those who apply these concepts to systems of practical chemical and physical interest. A key tradition in this meeting is the strong mixing of theory and experiment throughout. The program for 2010 conference continues these traditions. At the 2010 AMI GRC, there will be talks in 5 broadly defined and partially overlapping areas of intermolecular interactions and chemical dynamics: (1) Photoionization and Photoelectron Dynamics; (2) Quantum Control and Molecules in Strong Fields; (3) Photochemical Dynamics; (4) Complex Molecules and Condensed Phases; and (5) Clusters and Reaction Dynamics. These areas encompass many of the most productive and exciting areas of chemical physics, including both reactive and nonreactive processes, intermolecular and intramolecular energy transfer, and photodissociation and unimolecular processes. Gas phase dynamics, van der Waals and cluster studies, laser-matter interactions and multiple potential energy surface phenomena will all be discussed.

    1976-06-01

    The operation of the Karlsruhe Isochronous Cyclotron in 1975 is briefly surveyed. The main reasons for a very short period for maintenance, repair and installation, and several additional efforts to improve the reliability of the accelerator installation, are discussed. The status and the results of several technical developments for the cyclotron are described: 1) the axial injection system; 2) computer aided cyclotron operation; 3) ion source development; 4) capacitive current measurement at the external beam; 5) new correction coils for the cyclotron; 6) improvement of the neutron time-of-flight spectrometer. As there is an increasing interest in using this type of accelerator for research in fields other than nuclear physics, it was felt appropriate to present short surveys on investigations at our cyclotron in 1975 in the fields of: 1) solid state physics; 2) engineering; 3) materials research; 4) nuclear medicine; 5) nuclear chemistry.

    Radioactivity has been known for more than a hundred years. Nuclear data compilations through nuclide charts began in the 1920s with the work of Soddy, and were later rationalized in the Karlsruher Nuklidkarte. For 50 years, it has depicted the status of our nuclear knowledge in an easy reading form. It was born as an educational and scientific tool that gives access to the basic bricks that the nuclear Physics community needs to build the physics knowledge at the femtometer (10 -15 m) level. Nuclide data is a bridge between research and development. On the one hand, the nucleus can be regarded as a vast laboratory with, the possibility to test from fundamental concepts of the Standard Model to the genesis of the elements in the Universe. On the other hand, this data is also leading to applications in many areas of everyday life such as health care or environmental monitoring. (author)

The first criteria had a decisive influence on the roof arrangement, as an extension of the neighboring buildings, and on the selection of construction materials to match the suburban environment where the site is located, not to forget the shaping of Windows and skylights, reflecting the internal functions and providing lighting while protecting the privacy of the interior from the exterior lines of view. The second criteria affects aspects so different from one another as the unexpected but valid room arrangement following a spiral path leading from the entrance to the master bedroom at the other end with the remaining rooms at intermediate levels affording the required degree of privacy; or the arrangement of the mechanical installations, resembling the human backbone; or, finally, the paint finish chosen, pleasing man's taste for ornamentality.

    La realización de esta vivienda, en Karlsruhe, estuvo marcada por dos criterios fundamentales: la funcionalidad y la escala humana, llevadas ambas hasta sus últimas consecuencias. La primera influyó desde la disposición de las cubiertas, como prolongación de las construcciones vecinas, hasta la elección de los materiales constructivos, acordes con el entorno suburbano de la parcela, sin olvidar la configuración de las ventanas y lucernarios que, con sus diferentes formatos, indican el uso del interior, al tiempo que posibilitan la iluminación, protegiendo de las vistas exteriores. La segunda característica afecta a aspectos tan dispares como la original, pero válida, secuencia de habitaciones —según una espiral que, desde la entrada, conduce, en el extremo opuesto, al dormitorio de los padres, quedando las restantes dependencias situadas en los niveles intermedios según su exigencia

    Crasemann, B.; Wuilleumier, F.

    1985-01-01

    This chapter discusses applications of synchrotron light in atomic and molecular physics. Use of the radiation from storage rings has expanded and lent access to new areas of absorption and photoemission spectroscopy and scattering experiments. Techniques applied in connection with synchrotron radiation are discussed including absorption spectroscopy, photoelectron spectroscopy, fluorescence spectroscopy and X-ray scattering. Problem areas that are being studied by the techniques mentioned above are discussed. Synchrotron radiation has provided the means for measuring the threshold-excitation and interference effects that signal the breakdown of the two-step model of atomic excitation/deexcitation. Synchrotron radiation provides more means of excited-state photoionization measurements

    Fawcett, B.C.

    1990-07-01

    This report documents the atomic-structure research carried out during the period 1961-90. The contributions are in two main areas. The first comprises original line classifications of spectra of highly ionized atoms including identifications of a major proportion of newly observed lines in the solar far ultraviolet and soft X-ray spectrum. The second consists of theoretical calculations of atomic data such as oscillator strengths, wavelengths, energy levels and their composition. These were calculated with advanced atomic-structure codes and cover most solar abundant ions. A new method was applied to collision calculations. Research in this field, presently conducted at Rutherford Appleton Laboratory (RAL), was initiated in the United Kingdom Atomic Energy Authority (UKAEA) at Harwell in 1960. It continued under the UKAEA at Culham Laboratory in 1962 and until 1986 when staff were taken over by Science and Engineering Research Council (SERC) and later transferred to RAL in 1981. (author)

    An informal meeting to discuss ''Facilities for Atomic Physics Research with Highly Ionized Atoms'' was held during the APS DEAP meeting at the University of Connecticut on May 30, 1984. The meeting was motivated by the realization that the status of facilities for studies of highly ionized atoms is unsettled and that it might be desirable to take action to ensure adequate resources for research over the whole range of charge states and energies of interest. It was assumed that the science to be done with these beams has been amply documented in the literature

    2003-08-01

    Among the analytical techniques (mass spectrometry, laser Raman spectroscopy, gas chromatography, use of ionisation chambers) employed at the Tritium Laboratory Karlsruhe (TLK), gas chromatography plays a prominent role. The main reasons for that are the simplicity of the gas chromatographic separation process, the small space required for the equipment, the low investment costs in comparison to other methods, the robustness of the equipment, the simple and straightforward analysis and the fact that all gas species of interest (with the exception of water) can easily be detected by gas chromatographic means. The conventional gas chromatographs GC1 and GC2 used in the Tritium Measurement Techniques (TMT) System of the TLK and the gas chromatograph GC3 of the experiment CAPER are presented in detail, by discussing their flow diagrams, their major components, the chromatograms measured by means of various detectors, shortcomings and possible improvements. One of the main disadvantages of the conventional gas chromatography is the long retention times required for the analysis of hydrogen gas mixtures. To overcome this disadvantage, micro gas chromatography for hydrogen analysis was developed. Reduction of the retention times by one order of magnitude was achieved. (orig.)

  7. Cooperation between NIEP and Karlsruhe University in crust and upper mantle studies of the Vrancea area

    2002-01-01

    Active cooperation between seismologists at Bucharest and Karlsruhe started in 1974 with the installation of seismic stations at Romanian dam sites. These stations also recorded the destructive earthquake of 1977 and formed the nucleus for a broader cooperation between seismologists at Bucharest and Karlsruhe and was followed by a continuing exchange of knowledge by vice versa research visits. The cooperation was finally intensively increased by the installation of a major priority research program on earthquake risk problems of Karlsruhe University with Romanian research institutions in 1996, when Romanian and German scientists from various fields (geology, seismology, civil engineering, operation research) organized themselves in the Collaborative Research Center 461 (CRC 461) 'Strong earthquakes: a challenge for geosciences and civil engineering' (Germany) and the Romanian Group for Strong Vrancea Earthquakes (RGVE) in a multidisciplinary attempt towards earthquake mitigation. The cooperation between the Geophysical and Geological Institutes of Karlsruhe University with both NIEP and the Faculty of Geology of Bucharest University focussed in particular on the deep geology of the Vrancea area and surrounding provinces with emphasis on seismicity studies and crust and upper-mantle investigations. Two long-range seismic wide-angle profiles from Bacau to the Danube south of Bucharest recorded in 1999 and from Transylvania to the Dobrogea recorded in 2001, both crossing each other in the Vrancea area, will provide a detailed 3-dimensional crustal structure image of Vrancea and adjacent Carpathians and their surrounding basins, while a temporary array of 120 mobile stations distributed throughout southeastern Romania recorded local and far-distant earthquakes for about 6 months in 1999 which will allow to derive a 3-dimensional tomographic image of the underlying uppermost mantle to depths of about 300 km.

    Wisshak, K.; Guber, K.; Kaeppeler, F.; Krisch, J.; Mueller, H.; Rupp, G.; Voss, F.

    1989-12-01

    A new experimental approach has been implemented for accurate measurements of neutron capture cross sections in the energy range from 5 to 200 keV. The Karlsruhe 4π Barium Fluoride Detector consists of 42 crystals shaped as hexagonal and pentagonal truncated pyramids forming a spherical shell with 10 cm inner radius and 15 cm thickness. All crystals are supplied with reflector and photomultiplier, thus representing independent gamma-ray detectors. Each detector module covers the same solid angle with respect to a gamma-ray source located in the centre. The energy resolution of the 4π detector is 14% at 662 keV and 7% at 2.5 MeV gamma-ray energy, the overall time reslution is 500 ps and the peak efficiency 90% at 1 MeV. The detector allows to register capture cascades with 95% probability above a threshold energy of 2.5 MeV in the sum energy spectrum. Neutrons are produced via the 7 Li(p,n) 7 Be reaction using the pulsed proton beam of a Van de Graaff accelerator. The neutron spectrum can be taylored according to the experimental requirements in an energy range from 5 to 200 keV by choosing appropriate proton energies. A collimated neutron beam is passing through the detector and hits the sample in the centre. The energy of captured neutrons is determined via time of flight, the primary flight path being 77 cm. The combination of short primary flight path, a 10 cm inner radius of the spherical BaF 2 shell, and the low capture cross section of barium allows to discriminate background due to capture of sample scattered neutrons in the scintillator by time of flight, leaving part of the neutron energy range completely undisturbed.

    Rotating disk atomization technique is applied to KMRR (Korea Multi-purpose Research Reactor) fuel fabrication. A rotating disk atomizer is designed and manufactured locally and U-4.0 wt. % Si alloy powders are produced. The atomized powders are heat-treated to transform into U 3 Si and the mixture of U 3 Si and Al are extruded to fuel meat. Most of the atomized powders are spherical in shape. The microstructure of the powder is fine due to the rapid solidification. The time required for peritectoid reaction is reduced due to the fine microstructures and the resultant U 3 Si grain size is finer than ever obtained from ingot process. The mechanical properties of the fuel meat are improved: yield strength about 30 %, tensile strength 10% and elongation 250 % increased. (author)

    Caldarola, L.; Wickenhaeuser, A.

    1977-01-01

    A very fast analytical computer program for fault tree evaluation has already been developed at the German nuclear research center of Karlsruhe. This program can evaluate coherent systems assuming binary component states. Four different classes of components can be handled by the program: (1) unrepairable components, (2) repairable components with revealed faults, (3) repairable components with faults remaining unrevealed until next demand occurs and (4) repairable components with faults which are detected upon inspection. The program can perform also time dependent calculations. In particular the program can analyse systems characterized by two phases, one following the other in time (two time axis). A new computer program is also being developed. This computer program will be capable to analyse noncoherent systems with multistate components. The mathematical theory supporting the new program is described in the paper. In particular the algorithm for the identification of the prime implicants and the theory for the calculation of the occurrence probability and of the first occurrence probability of the TOP event are discussed

  17. Removing of the fuel element storage basin by explosive technique in the course of decommissioning of the Nuclear research reactor FR 2 in the research center Karlsruhe. Permission and technical execution

    International Nuclear Information System (INIS)

    Jehle, P.; Freund, H.U.

    1999-01-01

    The fuel element storage basin was removed by explosive technique in the course of the decommissioning of the nuclear research reactor FR 2. This basin consisted of 6.800 tons of heavily reinforced concrete with 25 tons of stainless steel lining. The reactor building including residual radioactive inventory was constructionally connected to the basin and had to stay undamaged. For this reason and due to the fact that the storage basin as operational part of the nuclear facility was subject to the German nuclear law the dismantling had to follow stringent licensing and control requirements. Special restrictions concerned the tolerable reactor building vibrations and the direct blast loadings which could affect the structural integrity of the building enclosing the basin. The explosive dismantling operations which also included the final removal of the building foundation were successfully performed in 90 separate blasts employing 490 kg of commercial explosives.

  20. The role of atomic and molecular processes in fusion research

    International Nuclear Information System (INIS)

    Harrison, M.F.A.

    1977-01-01

    This paper considers the relevance of atomic and molecular processes to research into controlled nuclear fusion and in particular their effects upon the magnetically confined plasma in Tokamak experiments and conceptual Tokamak reactors. The relative significance of collective phenomena and of single particle collisions to both plasma heating and loss processes are discussed and the pertinent principles of plasma refuelling and plasma diagnostics are outlined. The methods by which atomic and molecular data are applied to these problems, the contributing effects of surface interactions and the consequent implications upon the accuracy and the type of data needed are described in a qualitative manner. Whilst particular atomic and molecular processes are not discussed in detail, sufficient information is given of the physical environments of Tokamak devices for significant processes to be self evident.

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

    2011-01-01

    The Japan Atomic Energy Agency (JAEA) has been producing, collecting and compiling cross-section data for atomic and molecular collisions and spectral data relevant to fusion research. In this talk, an overview of our activities since the last meeting in September 2009 will be presented. The state selective charge transfer cross-section data of Be 4+ , C 4+ and C 6+ by collision with H(n=2) in the collision energy range between 62 eV/amu and 6.2 keV/amu have been calculated with a molecular-bases close-coupling method. The calculated charge transfer data of C 4+ was implemented in a collisional-radiative model code for C 3+ , and it is shown that in some cases the charge transfer from C 4+ to H(n=2) populates predominantly C 3+ (n = 6, 7). The cross-section data of dissociative recombination and excitation of HD + , D 2+ , DT + , T 2+ 3 HeH + and 4 HeH + were produced by theoretical calculation. The principal quantum number of dissociated H atom isotopes was also given. The analytical expressions for the cross-section data for 26 processes of He-collision systems were produced in order to facilitate practical use of the data. The compiled data are in preparation for the web site at the URL of http://www-jt60.naka.jaea.go.jp/engish/JEAMDL/. The chemical sputtering yield data of CFC materials with hydrogen isotope collisions have been compiled. The ionization rate of W 44+ and the radiative and the dielectronic recombination rates of W 45+ were calculated with FAC. The ratio of these rates was compared with experimentally measured ratio of W 45+ density to W 44+ density in JT-60U, showing that the calculated ratio of the recombination ratio of W 45+ to the ionization rate of W 44+ is accurate within the experimental uncertainty (∼ 30%). The atomic and molecular data activities in JAEA are pursued in collaboration with Japanese universities, and other department of JAEA. (author)

  12. The ''Nuclear-Karlsruhe'' air-filter system

    International Nuclear Information System (INIS)

    Berliner, P.; Ohlmeyer, M.; Stotz, W.

    1976-01-01

    Increasing requirements for exhaust-air filter systems used in nuclear facilities induced the Gesellschaft fuer Kernforschung to develop the ''Nuclear-Karlsruhe'' HEPA filter system. This novel development has profited by experience gained in previous incidents as well as by maitenance and decontamination work performed with different HEPA filter systems. The proved ''Nuclear-Karlsruhe'' system takes equally into account the demands for optimum safety, maximum efficiency and economy, and is distinguished by the following features: (1) The air current is defected by 180 0 in the casing. Deflection causes quite a number of improvements, results in substantial reduction of space requirements, and avoids the dispersion of pollutants to the clean-air side. Besides, the HEPA filter is protected from damage by condensed particles or foreign materials entrained; (2) The ''Nuclear-Karlsruhe'' system allows gas-tight filter replacement. Special replacement collars have been provided at the casing, which allow the tight fastening of replacement bags which are self-locking. (3) In-place testing in the operating condition can be carried out very conveniently because the air is deflected. Minimum leaks in the filter medium or in the filter gasket can be detected by the high-sensitivity visual oil-thread test, which makes leaks distinctly visible as oil mist threads through a transparent front window provided on the clean-air side. The test takes only some minutes and its sensitivity is hardly matched by any other technique. (4) The clamping mechanism is installed outside the casing, i.e. outside the polluted or aggressive media. The contact force is spring-loaded absolutely uniformly to the circular filter gasket. (5) For practical and econmic reasons the filter casings can be locked individually so as to be gas-tight. (6) The entire system is made of stainless or coated steel and metal parts which are corrosion and fire-resistant. (author)

    1977-06-01

    Research and development activities are being conducted on many aspects of the atomic uranium laser isotope separation process. Extensive laser spectroscopy studies have been made in order to identify attractive multi-step selective ionization schemes. Using low density (10 10 atoms/cm 3 ) apparatus, the excited state spectra of atomic uranium have been investigated via multiple step laser excitation and photoionization studies using two, three and four pulsed lasers. Observation of the spectra was accomplished by observing the yield of 235 U and 238 U ions as a function of the wavelength, intensities and delays of the various lasers. These data yielded information on the photoexcitation and photoionizatin cross sections, and on the location, J values, lifetimes, isotope shifts and hyperfine structure of the various atomic levels of uranium. Experiments on selective ionization of uranium vapor by multiple step laser excitation followed by ion extraction at 10 13 atoms/cm 3 density have produced 6% enriched 235 U. These indicate that this process is well adapted to produce light water reactor fuel but less suitable for highly enriched material. Application has been made for license for a 1979 experimental facility to provide data for a mid-1980 commercial plant

  19. Ultralow temperature helium compressor for Japan Atomic Energy Research Institute

    International Nuclear Information System (INIS)

    Asakura, Hiroshi

    1988-01-01

    Ishikawajima Harima Heavy Industries Co., Ltd. started the development of an ultralow temperature helium compressor for helium liquefaction in 1984 jointly with Japan Atomic Energy Research Institute, and has delivered the first practical machine to the Superconductive Magnet Laboratory of JAERI. For a large superconductive magnet to be used in the stable state for a fusion reactor, conventional superconductive materials (NbTi, NbTi 3 Sn, etc.) must be used, being cooled forcibly with supercritical helium. The supercritical helium which is compressed above the critical pressure of 228 kPa has a stable cooling effect since the thermal conductivity does not change due to the evaporation of liquid helium. In order to maintain the temperature of the supercritical helium below 4 K before it enters a magnet, a heat exchanger is used. The compressor that IHI has developed has the ability to reduce the vapor pressure of liquid helium from atmospheric pressure to 50.7 kPa, and can attain the temperature of 3.5 K. The specification of this single stage centrifugal compressor is: mass flow rate 25 - 64 g/s, speed 80,000 rpm, adiabatic efficiency 62 - 69 %. The structure and the performance are reported. (K.I.)

    2013-06-01

    Full Text Available Atomic force microscopy (AFM is a three-dimensional topographic technique with a high atomic resolution to measure surface roughness. AFM is a kind of scanning probe microscope, and its near-field technique is based on the interaction between a sharp tip and the atoms of the sample surface. There are several methods and many ways to modify the tip of the AFM to investigate surface properties, including measuring friction, adhesion forces and viscoelastic properties as well as determining the Young modulus and imaging magnetic or electrostatic properties. The AFM technique can analyze any kind of samples such as polymers, adsorbed molecules, films or fibers, and powders in the air whether in a controlled atmosphere or in a liquid medium. In the past decade, the AFM has emerged as a powerful tool to obtain the nanostructural details and biomechanical properties of biological samples, including biomolecules and cells. The AFM applications, techniques, and -in particular- its ability to measure forces, are not still familiar to most clinicians. This paper reviews the literature on the main principles of the AFM modality and highlights the advantages of this technique in biology, medicine, and- especially- dentistry. This literature review was performed through E-resources, including Science Direct, PubMed, Blackwell Synergy, Embase, Elsevier, and Scholar Google for the references published between 1985 and 2010.

    When this contribution was prepared, the author decided to present the more personal aspects of his work and the concepts that directed him. Since the time when the author interested in solid state hot atom chemistry more than 30 years ago, still now the generally accepted theory has not been existed. The irradiation test by using the BEPO pile in Harwell is reported. The use of glass fiber paper instead of cellulose paper was investigated. The real problem of the different models of primary retention should be solved. The idea of mixed crystal systems was the result of an experimental accident. The attempt of preparing mixed crystals, the papers that the author has written, the procedures of the experiment such as electrophoresis, the results of the electrophoretic separation are discussed. The next step was obviously the investigation of the ligand recoil. The production of the transient ligand vacancy complexes and their final fate resulted in mixed hexachlorobromometallate species is shown for the system K 2 O s Cl 6 -K 2 O s Br 6 (n,γ) 38 Cl. The reaction of the 38 Cl, the information about recoil atom reactions which increased with the complexity of target substances, and the resulted informations are reported. (K.I.)71 refs

    1984-01-01

    The review based on the experimental works of USA, West Germany scientists, the scientists of LNP JINR, shows the possibilities of muon atom application for comparative element analysis in biology and medicine. The unique and wide possibilities of muon diagnosis method are shown. Experiments both in vitro and in vivo were conducted. Investigation resulted in demonstration of variation of C, N, O amount in investigated tissue samples; the relative oxygen content grows in progression: adipose tissue, muscular tissue, liuer, blood. It is shown that the method enables to determine the content of any element no matter in what chemical compound this element enters. The method of muon atoms has some advantages as compared with other nuclear physics methods. Method restriction lies in the absence of high-intensive meson beams, which is related to method sensitivity. Another disadvantage consists in impossibility to register hydrogen therefore the method must be expanded by other methods of analysis for the purpose of investigation of different functional changes in organism

    The Tritium Laboratory Karlsruhe (TLK) accomplished commissioning; tritium involving activities will start this year. The laboratory is destined mainly to investigating processing of fusion reactor fuel and to developing analytic devices for determination of tritium and tritiated species in view of control and accountancy requirements. The area for experimental work in the laboratory is about 800 m{sup 2}. The tritium infrastructure including systems for tritium storage, transfer within the laboratory and processing by cleanup and isotope separation methods has been installed on an additional 400 m{sup 2} area. All tritium processing systems (=primary systems), either of the tritium infrastructure or of the experiments, are enclosed in secondary containments which consist of gloveboxes, each of them connected to the central depressurization system, a part integrated in the central detritiation system. The atmosphere of each glovebox is cleaned in a closed cycle by local detritiation units controlled by two tritium monitors. Additionally, the TLK is equipped with a central detritiation system in which all gases discharged from the primary systems and the secondary systems are processed. All detritiation units consist of a catalyst for oxidizing gaseous tritium or tritiated hydrocarbons to water, a heat exchanger for cooling the catalyst reactor exhaust gas to room temperature, and a molecular sieve bed for adsorbing the water. Experiments with tracer amounts of tritium have shown that decontamination factors >3000 can be achieved with the TLK detritiation units. The central detritiation system was carefully tested and adjusted under normal and abnormal operation conditions. Test results and the behavior of the tritium barrier preventing tritiated exhaust gases from escaping into the atmosphere will be reported.

    An almost quantitative retention of iodine is required in reprocessing plants. For the iodine removal in the off-gas streams of a reprocessing plant various sorption materials had been tested under realistic conditions in the Karlsruhe reprocessing plant WAK in cooperation with the Karlsruhe research center FZK. The laboratory results achieved with different iodine sorption materials justified long time performance tests in the WAK Plant. Technical iodine filters and sorption materials for measurements of iodine had been tested from 1972 through 1992. This paper gives an overview over the most important results, Extended laboratory, pilot plant, hot cell and plant experiences have been performed concerning the behavior and the distribution of iodine-129 in chemical processing plants. In a conventional reprocessing plant for power reactor fuel, the bulk of iodine-129 and iodine-127 is evolved into the dissolver off-gas. The remainder is dispersed over many aqueous, organic and gaseous process and waste streams of the plant. Iodine filters with silver nitrate impregnated silica were installed in the dissolver off-gas of the Karlsruhe reprocessing plant WAK in 1975 and in two vessel vent systems in 1988. The aim of the Karlsruhe iodine research program was an almost quantitative evolution of the iodine during the dissolution process to remove as much iodine with the solid bed filters as possible. After shut down of the WAK plant in December 1990 the removal efficiency of the iodine filters at low iodine concentrations had been investigated during the following years. 12 refs., 2 figs., 2 tabs

    1990-01-01

    On the smoking occurred on May 30, 1989 in the uranium enrichment research building, the investigation has been carried out about the presumed cause and the countermeasures for preventing the recurrence, and the following report was presented. In the uranium scrap after the oxidation treatment of vapor-deposited metallic uranium was carried out, a small quantity of unoxidized part having reactivity remained. This unoxidized part existing locally reacts with air in a container, and there is the possibility of generating heat after about one day. In this accident, unoxidized part existed near the wall of a polyethylene vessel, and the oxidation and heat generation reaction advanced. The vessel broke, air supply increased, and heat generation spread. After the temperature reached 300degC, the oxidation of UO 2 to U 3 O 8 took part, thus the polyethylene vessel and others generated smoke. As the countermeasures, for the preservation of uranium scrap, metallic vessels are used, and the atmosphere of inert gas or vacuum is maintained. The uranium scrap containing unoxidized part is rapidly oxidized. The uranium enrichment research building was decontamination. (K.I.)

  14. Noncontact Atomic Force Microscopy: An Emerging Tool for Fundamental Catalysis Research.

    Although atomic force microscopy (AFM) was rapidly adopted as a routine surface imaging apparatus after its introduction in 1986, it has not been widely used in catalysis research. The reason is that common AFM operating modes do not provide the atomic resolution required to follow catalytic processes; rather the more complex noncontact (NC) mode is needed. Thus, scanning tunneling microscopy has been the principal tool for atomic scale catalysis research. In this Account, recent developments in NC-AFM will be presented that offer significant advantages for gaining a complete atomic level view of catalysis. The main advantage of NC-AFM is that the image contrast is due to the very short-range chemical forces that are of interest in catalysis. This motivated our development of 3D-AFM, a method that yields quantitative atomic resolution images of the potential energy surfaces that govern how molecules approach, stick, diffuse, and rebound from surfaces. A variation of 3D-AFM allows the determination of forces required to push atoms and molecules on surfaces, from which diffusion barriers and variations in adsorption strength may be obtained. Pushing molecules towards each other provides access to intermolecular interaction between reaction partners. Following reaction, NC-AFM with CO-terminated tips yields textbook images of intramolecular structure that can be used to identify reaction intermediates and products. Because NC-AFM and STM contrast mechanisms are distinct, combining the two methods can produce unique insight. It is demonstrated for surface-oxidized Cu(100) that simultaneous 3D-AFM/STM yields resolution of both the Cu and O atoms. Moreover, atomic defects in the Cu sublattice lead to variations in the reactivity of the neighboring O atoms. It is shown that NC-AFM also allows a straightforward imaging of work function variations which has been used to identify defect charge states on catalytic surfaces and to map charge transfer within an individual

    The Department of Atomic Physics at Plovdiv University has 40 year long experience in educating students in Atomic and Subatomic Physics. We aim at making the knowledge gained in nuclear physics part of the culture of our students. At the core of our educational activities lies our long and successful experience in studying the characteristics of atomic nuclei. In cooperation with JINR-Dubna we have studied the nuclei of approximately 40 percent of the periodic table elements. These studies also serve as a basis for the diverse implementation activities of the Department, which have an impressive geographical spread. In recent years our research has been focusing more specifically on radio-ecological issues with the valuable support of the Nuclear Regulatory Agency (NRA). Future more intense support on behalf of NRA's together with more dynamic links with other specialized units, such as the Kozloduy NPP in the first place, would considerably contribute to optimizing the effect of our overall activity.

    1995-01-01

    The article presents a historic-methodological analysis of the scientific heritage of an outstanding Swiss physicist Walter Ritz (1878-1909); the analysis is based on the study of a complete collection of his works published in 1911. In addition to a general description of Ritz's works which comprise publications in spectroscopy, variational method and electrodynamics, the article deals in detail with this fundamental research into atomic spectra theory. Elastic and magnetic model of the atom proposed by Ritz for explaining atomic spectra within the framework of the classical approach are discussed. It is shown that the generalized formulas of Balmer and Rydbery, as well as the combination principle which served later as a basis for formalting Bohr's condition of frequencies, were derived by Ritz as regions corollaries of this models and were out of semiempiric nature, as was assumed. 124 refs

  15. Report on the first two IAEA-courses on nuclear power project planning and implementation in Karlsruhe

    Reuter, H.H.

    1977-01-01

    There is no more doubt about the necessity of utilizing nuclear energy to cover the world energy requirements. A growing number of developing countries find themselves compelled to use nuclear energy in order to meet their rising energy demands and, hence, to improve their conditions of life. On the other hand, the lack of suitable experts having gathered experience is particularly perceptible in these countries. For this reason, IAEA has organized training courses on an international level, which are held in Karlsruhe (Federal Republic of Germany), Saclay (France), and Argonne (USA). Taking into account the situation in the respective developing country, independent courses are being offered on ''Nuclear Power Project Planning and Implementation'' and on ''Construction and Operation Management.'' The first course of this type was held at the Karlsruhe Nuclear Research Center from September 8 until December 17, 1975. It was attended by 35 participants from 20 countries. In cooperation with industry and national as well as international authorities the syllabus proposed by IAEA was translated into a training program including all essential questions on the introduction of nuclear energy in developing countries. The next course will take place from September 6 until November 30, 1976. A detailed analysis is presented of the extent to which the expectations of participants have been fulfilled. The status of nuclear technology and the number of candidates having sufficient knowledge is of particular importance in this context. A very significant aspect consists in teaching not only theoretical knowledge but integrating practical application in such training courses, which is demonstrated by examples

    In collaboration with the Naka Fusion Institute of Japan Atomic Energy Agency (NFI/JAEA) and the National Institute for Fusion Science of National Institute of Natural Science (NIFS/NINS), Center for Computational Science and E-systems of Japan Atomic Energy Agency (CCSE/JAEA) aims at establishing an integrated framework for experiments and analyses in nuclear fusion research based on the atomic energy grid infrastructure (AEGIS). AEGIS has been being developed by CCSE/JAEA aiming at providing the infrastructure that enables atomic energy researchers in remote locations to carry out R and D efficiently and collaboratively through the Internet. Toward establishing the integrated framework, we have been applying AEGIS to pre-existing three systems: experiment system, remote data acquisition system, and integrated analysis system. For the experiment system, the secure remote experiment system with JT-60 has been successfully accomplished. For the remote data acquisition system, it will be possible to equivalently operate experimental data obtained from LHD data acquisition and management system (LABCOM system) and JT-60 Data System. The integrated analysis system has been extended to the system executable in heterogeneous computers among institutes

    2004-01-12

    This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programs Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of

    1999-01-01

    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.

  12. Neutral atom analyzers for diagnosing hot plasmas: A review of research at the ioffe physicotechnical institute

    International Nuclear Information System (INIS)

    Kislyakov, A. I.; Petrov, M. P.

    2009-01-01

    Research on neutral particle diagnostics of thermonuclear plasmas that has been carried out in recent years at the Ioffe Physicotechnical Institute of the Russian Academy of Sciences (St. Petersburg, Russia) is reviewed. Work on the creation and improvement of neutral atom analyzers was done in two directions: for potential applications (in particular, on the International Thermonuclear Experimental Reactor, which is now under construction at Cadarache in France) and for investigation of the ion plasma component in various devices (in particular, in the largest tokamaks, such as JET, TFTR, and JT-60). Neutral atom analyzers are the main tool for studying the behavior of hydrogen ions and isotopes in magnetic confinement systems. They make it possible to determine energy spectra, to perform the isotope analysis of atom fluxes from the plasma, to measure the absolute intensity of the fluxes, and to record how these parameters vary with time. A comparative description of the analyzers developed in recent years at the Ioffe Institute is given. These are ACORD-12/24 analyzers for recording 0.2-100-keV hydrogen and deuterium atoms with a tunable range of simultaneously measured energies, CNPA compact analyzers for a fixed energy gain in the ranges 80-1000 eV and 0.8-100 keV, an ISEP analyzer for simultaneously recording the atoms of all the three hydrogen isotopes (H, D, and T) in the energy range 5-700 keV, and GEMMA analyzers for recording atom fluxes of hydrogen and helium isotopes in the range 0.1-4 MeV. The scintillating detectors of the ISEP and GEMMA analyzers have a lowered sensitivity to neutrons and thus can operate without additional shielding in neutron fields of up to 10 9 n/(cm 2 s). These two types of analyzers, intended to operate under deuterium-tritium plasma conditions, are prototypes of atom analyzers created at the Ioffe Institute for use in the International Thermonuclear Experimental Reactor. With these analyzers, a number of new results have been

    The temporal losses of confinement during edge localized modes in the Japan Atomic Energy Research Institute Tokamak-60 Upgrade (JT-60U) show multifractal scaling and the spectra are generally smooth, but in some cases there are signs of discontinuous derivatives. Dynamics of the Sugama-Horton model, interpreted as edge localized modes, also display multifractal scaling. The spectra display singularities in the derivative, which can be interpreted as a phase transition. It is argued that the multifractal spectra of edge localized modes can be used to discriminate between different experimental discharges and validate edge localized mode models

    Transient-tested high burn-up fuel samples were investigated by electron microscopy to study the effect of strain on fission product distribution, and the concentration of (U,Pu)O 2 agglomerates in irradiated MOX fuel was examined by electron microprobe analysis. Conclusions on maximum temperatures to which the core of the Three Mile Island reactor was exposed could be drawn from an examination of TMI fuel debris. Equipment to measure thermophysical fuel properties for reactor safety studies was further developed. An improved version (slice version) of the TRANSURANUS fuel pin code was tested and released for external use. Safety Aspects of Fuel Operation and Handling were dealt with by improving preparation methods of (U,Pu)N. Release and resuspension of radioactive dust particles in fires was studied. The principal objective of the Actinide Determination and Recycling activity was the reduction of long-term hazards of alpha-bearing nuclear waste. The long-term storage behaviour of UO 2 and MOX spent fuel samples as well as of vitrified waste forms was further investigated by studying the effect of leaching. The electronic structure of the transuranium elements is the central objective of basic Actinide Research. A large number of ternary alloys containing Np or Pu and Si or Ge, together with a transition metal was prepared for basic experimental studies. New high-pressure phases were discovered in PuSe, UPS, ThO 2 , and PuO 2 . Analytical techniques were evaluated and automated for safeguards. A multiwavelength pyrometer was adapted for industrial use. Major contracts with Third Parties were dealing with the development of minor actinide alloys, and the post-irradiation examination of high burn-up UO 2 and MOX fuel from LWR power stations

    Pulses are the cheapest source of protein for the predominantly vegetarian population of India. However per capita availability of pulses is reduced due to high growth of population and only marginal increase in pulses production. Development of varieties resistant to biotic and abiotic stresses will help to increase and stabilize pulse production in the country. Research work for the improvement of the three important pulse crops namely pigeon pea, mungbean and black gram was initiated using induced mutation approaches in early 70' and recently for cowpea and soybean at the Nuclear Agriculture and Biotechnology Division of the Bhabha Atomic Research Centre, Mumbai. The programme for developing disease resistant high yielding varieties is being pursued at NABTD, BARC using induced mutations and conventional breeding approaches

    International Nuclear Information System (INIS)

    Arnecke, G.; Borgwaldt, H.; Brandl, V.; Lalovic, M.

    1974-01-01

    The Karlsruhe Monte Carlo Code KAMCCO is a forward neutron transport code with an eigenfunction and a fixed source option, including time-dependence. A continuous energy model is combined with a detailed representation of neutron cross sections, based on linear interpolation, Breit-Wigner resonances and probability tables. All input is processed into densely packed, dynamically addressed parameter fields and networks of pointers (addresses). Estimation routines are decoupled from random walk and analyze a storage region with sample records. This technique leads to fast execution with moderate storage requirements and without any I/O-operations except in the input and output stages. 7 references. (U.S.)

    A computer aided process control system has been installed at the Karlsruhe Spent Fuel Reprocessing Plant, WAK. All necessary process control data of the first extraction cycle is collected via a data collection system and is displayed in suitable ways on a screen for the operator in charge of the unit. To aid verification of displayed data, various measurements are associated to each other using balance type process modeling. Thus, deviation of flowsheet conditions and malfunctioning of measuring equipment are easily detected. (orig.) [de

    Shimizu, Y.; Schull, W.J.; Kato, H.

    1990-01-01

    This article summarizes the risk of cancer among the survivors of the atomic bombing of Hiroshima and Nagasaki. We focus primarily on the risk of death from cancer among individuals in the Life Span Study sample of the Radiation Effects Research Foundation from 1950 through 1985 based on recently revised dosimetry procedures. We report the risk of cancer other than leukemia among the atomic bomb survivors. We note that the number of excess deaths of radiation-induced malignant tumors other than leukemia increases with age. Survivors who were exposed in the first or second decade of life have just entered the cancer-prone age and have so far exhibited a high relative risk in association with radiation dose. Whether the elevated risk will continue or will fall with time is not yet clear, although some evidence suggests that the risk may be declining. It is important to continue long-term follow-up of this cohort to document the changes with time since exposure and to provide direct rather than projected risks over the lifetime of an exposed individual

    2001-01-01

    Abstract. KAERI (Korea Atomic Energy Research Institute), a national nuclear research institute in the Republic of Korea, celebrated its fortieth anniversary last April. It has played a key role in the Korean nuclear history such that it: initiated and promoted the peaceful uses of nuclear energy in the Republic of Korea; maintained nuclear expertise on whole spectrum of nuclear field through conducting nuclear R and D programs, operating nuclear research facilities, and training and educating specialized nuclear personnel; founded a cornerstone of Korean nuclear industry by participating in the establishment of a nuclear engineering company and a nuclear fuel company and localizing nuclear fuel and reactor technology; and contributed to nuclear safety regulation by incubating a specialized nuclear regulatory body. Recently, to concentrate on nuclear R and D on advanced technology, KAERI went through management reform such as: the transfer of nuclear engineering divisions responsible for NSSS design and nuclear fuel design to nuclear industry in 1996; and the downsizing of manpower in 1998. Currently KAERI is in the challenging stage in terms of its missions and manpower. In the coming 21st century, KAERI is required to maintain the current R and D momentum and also to conduct priority-based research requiring concentrated effort. (author)

    1974-01-01

    Within the overall federal geothermal program, the Atomic Energy Commission has chosen to concentrate on development of resource utilization and advanced research and technology as the areas most suitable to the expertise of its staff and that of the National Laboratories. The Commission's work in geothermal energy is coordinated with that of other agencies by the National Science Foundation, which has been assigned lead agency by the Office of Management and Budget. The objective of the Commission's program, consistent with the goals of the total federal program is to facilitate, through technological advancement and pilot plant operations, achievement of substantial commercial production of electrical power and utilization of geothermal heat by the year 1985. This will hopefully be accomplished by providing, in conjunction with industry, credible information on the economic operation and technological reliability of geothermal power and use of geothermal heat.

    1987-01-01

    Integrated library system has been developed using a stand-alone mini-computer in the Japan Atomic Energy Research Institute library. This system consists of three subsystems for serials control, books acquisition and circulation control. Serials control subsystem deals with subscription, acquisition, claiming and inquiry of journals. This has been operating since the beginning of 1985. Book acquisition sub-system, which has been started since April 1986, deals with accounting and cataloguing of books. Circulation control sub-system deals with circulation, statistics compilation, book inventory and retrieval, which has been operating since April 1987. This system contributes greatly not only to the reduction of the circulation work load but also to the promotion of the library services. However, the convenience in circulation processing should be improved for materials without catalogue information stored in the computer. The pertinence for maximum number of books retrieved has to be also reconsidered. (author)

    1984-01-01

    Study of the atomic bomb survivors has provided uniquely valuable information about the types of effects that are produced by ionizing radiation and their relation to dose, age at exposure, time after irradiation, and other variables. There are still, however, many unresolved questions requiring further investigation. These include reassessment of the dosimetry in both Hiroshima and Nagasaki; continued follow-up of survivors for cancer and other late effects, especially those who were exposed early in life and are just now reaching the age when the common cancers of adult life make their appearance; further evaluation of the possibility of measuring genetic effects in the children of survivors; and continued longitudinal investigation of risk factors predisposing to cancer, preneoplastic lesions, and other diseases. To the extent that a strong statistical foundation is essential to such investigations, the high calibre and sophistication of ongoing statistical research at RERF augers well for the future. 30 references, 4 figures

    Rational treatment of a large volume of solid wastes resulting from the reactor dismantling is a key to success to carry out the decommissioning smoothly. From this viewpoint, the Japan Atomic Energy Research Institute (JAERI) has been conducting development of the recycling technology for metal waste and an investigation study on the rational recycling system for the dismantling wastes recycling. With respect to the development of the recycling technology, series of melting tests using non-contaminated metals, metal waste dismantled from JPDR or imitated waste using radioisotopes have been conducted. The basic characteristics of the radionuclides transport behavior during the melting have been understood. In the investigation study on the rational recycling system, a scenario of recycling the wastes was developed based on the amount of waste arising from decommissioning nuclear power plants, and necessary processing facilities were examined, and safety and economy of the process were evaluated

    1998-01-01

    The fifth Atomic Energy Research dynamic benchmark is the first Atomic Energy Research benchmark for coupling of the thermohydraulic codes and three-dimensional reactor dynamic core models. In VTT HEXTRAN 2.7 is used for the core dynamics and SMABRE 4.6 as a thermohydraulic model for the primary and secondary loops. The plant model for SMABRE is based mainly on two input models. the Loviisa model and standard WWER-440/213 plant model. The primary circuit includes six separate loops, totally 505 nodes and 652 junctions. The reactor pressure vessel is divided into six parallel channels. In HEXTRAN calculation 176 symmetry is used in the core. In the sequence of main steam header break at the hot standby state, the liquid temperature is decreased symmetrically in the core inlet which leads to return to power. In the benchmark, no isolations of the steam generators are assumed and the maximum core power is about 38 % of the nominal power at four minutes after the break opening in the HEXTRAN-SMABRE calculation. Due to boric acid in the high pressure safety injection water, the power finally starts to decrease. The break flow is pure steam in the HEXTRAN-SMABRE calculation during the whole transient even in the swell levels in the steam generators are very high due to flashing. Because of sudden peaks in the preliminary results of the steam generator heat transfer, the SMABRE drift-flux model was modified. The new model is a simplified version of the EPRI correlation based on test data. The modified correlation behaves smoothly. In the calculations nuclear data is based on the ENDF/B-IV library and it has been evaluated with the CASMO-HEX code. The importance of the nuclear data was illustrated by repeating the benchmark calculation with using three different data sets. Optimal extensive data valid from hot to cold conditions were not available for all types of fuel enrichments needed in this benchmark.(Author)

    Activities at Bhabha Atomic Research Centre (BARC), Mumbai, cover nuclear fuel cycle operations based on natural uranium as the fuel. The facilities include: plant for purification and production of nuclear grade uranium metal, fuel fabrication, research reactor operation, fuel reprocessing and radioactive waste management in each stage. Comprehensive radiation protection programmes for assessment and monitoring of radiological impact of these operations, both in occupational and public environment, have been operating in BARC since beginning. These programmes, based on the 1990 ICRP Recommendations as prescribed by national regulatory body, the Atomic Energy Regulatory Board (AERB), are being successfully implemented by the Health, Safety and Environment Group, BARC. Radiation Hazards Control Units attached to the nuclear fuel cycle facilities provide radiation safety surveillance to the various operations. The radiation monitoring programme consists of measurement and control of external exposures by thermoluminescent dosimeters (TLDs), hand-held and installed instruments, and internal exposures by bioassay and direct whole body counting using shadow shield counter for beta gamma emitters and phoswich detector based system for plutonium. In addition, an environmental monitoring programme is in place to assess public exposures resulting from the operation of these facilities. The programme involves analysis of various matrices in the environment such as bay water, salt, fish, sediment and computation of resulting public exposures. Based on the operating experience in these plants, improved educating and training programmes for plant operators, have been designed. This, together with the application of new technologies have brought down individual as well as average doses of occupational workers. The environmental releases remain a small fraction of the authorised limits. The operating health physics experience in some of these facilities is discussed in this paper

    The scaling analysis produced the design parameters of the MCT facility, and the manufacturing process is ongoing. The application of the optical fluid measurements to the MCT was preliminary tested by small scale test models. The various flow patterns arising from a complex interaction between the buoyancy and inertia forces can be simulated in the MCT facility. In addition, the experimental results will be compared with the CFD results. The Korea Atomic Energy Research Institute (KAERI) started experimental research on moderator circulation as one of its national R and D research programs in 2012. In the present paper, we introduce a scaling analysis performed to extend the scaling criteria suitable for reproducing thermal-hydraulic phenomena in a scaled-down CANDU-6 moderator tank, 1/40 and 1/8 small-scale model tests to identify the potential problems of the flow visualization and measurement in the main 1/4 scale MCT (Moderator Circulation Test) facility, a manufacturing status of the 1/4 scale moderator tank, and preliminary CFD analysis results to determine the flow, thermal, and heating boundary conditions with which the various flow patterns expected in the prototype CANDU-6 moderator tank can be reproduced in the experiment. KAERI has launched an experimental program for moderator circulation in a CANDU6 reactor.

    1991-01-01

    The Advanced Light Source, a third-generation national synchrotron-radiation facility now under construction at the Lawrence Berkeley Laboratory, is scheduled to begin serving qualified users across a broad spectrum of research areas in the spring of 1993. Based on a low-emittance electron storage ring optimized to operate at 1.5 GeV, the ALS will have 10 long straight sections available for insertion devices (undulators and wigglers) and 24 high-quality bend-magnet ports. The short pulse width (30-50 ps) will be ideal for time-resolved measurements. Undulators will generate high-brightness partially coherent soft X-ray and ultraviolet (XUV) radiation from below 10 eV to above 2 keV; this radiation is plane polarized. Wigglers and bend magnets will extend the spectrum by generating high fluxes of X-rays to photon energies above 10 keV. The ALS will have an extensive research program in which XUV radiation is used to study matter in allk its varied gaseous, liquid, and solid forms. The high brightness will open new areas of research in the materials sciences, such as spatially resolved spectroscopy (spectromicroscopy), and in biology, such as X-ray microscopy with element-specific sensitivity; the high flux will allow measurements in atomic physics and chemistry to be made with tenuous gas-phase targets. Technological applications could include lithography and nano-fabrication. (orig.)

    The aim of this thesis is the description of the process of institutionalization of nuclear research in Austria in the context of the „Atoms for Peace“ program in the 1950s. This aspect of the history of Austrian nuclear research has been relatively unexplored. The focus of this work is the presentation of measures that have been put in Austria to participate in the 'Atoms for Peace' program. Moreover, the expectations and goals of the Austrian nuclear program are analyzed. For this purpose, foundation, structure and research activities of the “Austrian Atomic Energy Commission”, the “Austrian Society for the Study of Atomic Energy” and the “Nuclear Reactor Centre Seibersdorf“ in the period from 1954 until about 1970 are examined. To establish a relationship with the international historical research of the history of nuclear research, the Austrian situation is compared to the Swiss and the German. It turns out that the Austrian expectations and objectives in nuclear research at the beginning of the period of observation roughly corresponded with the international trends. It also follows that by the establishment of the SGAE and the “Nuclear Reactor Centre Seibersdorf“ the development course of Austrian nuclear research occupied a special position compared to foreign institutions.(author) [de

    2012-01-01

    The popularity of optically stimulated luminescence (OSL) technology in the radiation dosimetry applications, in general, and personnel and environmental monitoring, in particular, has driven investigation and developmental programme using OSL technique for a viable system for personnel monitoring at Bhabha Atomic Research Centre. The OSL related phosphor materials and instrumentation development has a very recent history in Bhabha Atomic Research Centre. The OSL technique is more versatile and easy to use than thermoluminescence (TL) technique. The X- and gamma ray (both high and low energy) photons and beta particles can be measured with OSL technique. In the OSL technique, the phosphor (say á- Ai 2 O 3 :C) is optically stimulated by blue/green light and the resulting light emitted from Al 2 O 3 :C (410-420 nm) is measured and correlated to the amount of radiation exposure. For a fixed stimulation intensity, the emitted blue light from the Al 2 O 3 :C dosimeter is proportional to the radiation exposure. The OSL technology is being increasingly used in several applications in external radiation dosimetry, in-vivo medical dosimetry in radiotherapy, in-situ, long-term monitoring system for radioactive contaminants, geological and archaeological dating of sediments, etc. For the success of OSL technology for large scale countrywide personnel monitoring program, indigenous development of dosimetric grade sensitive detector material was a key issue. Therefore, since 2002, efforts were directed towards the development of OSL phosphors (like aluminum oxide doped with carbon, á- Al 2 O 3 :C) and related instrumentation. To begin with, simple low cost OSL readers were developed using blue (470 nm) and green (530 nm) LED clusters. New techniques were developed for the preparation of dosimetric grade á- Ai 2 O 3 :C and other OSL phosphors. With the success in the development of indigenous technique for the large scale preparation of á- Al 2 O 3 :C phosphor, a four

    Since starting the research and development program for peaceful use of nuclear energy in 1950's, various research and demonstration facilities have been constructed in research organizations, universities and commercial sectors in Japan. Some of the nuclear facilities constructed in the early stage of research and development have been retired to be decommissioned because of completion of the initial objectives in the Japan Atomic Energy Research Institute (JAERI). On the other hand, since the first commercial operation of nuclear power plant (1968), the number of nuclear power plants has increased up to 52 plants operating as of August 2003 in Japan. The shear of nuclear energy accounts approximately for 35% of electricity generation in total at present time. However, several nuclear power plants have been operated for more than 25 years and two nuclear power plants are expected to be finally shutdown by 2010 to be eventually decommissioned. The Tokai Power Station, the oldest Japanese nuclear power plant operated by the Japan Atomic Power Company, was permanently shutdown from March 1998 and it is in decommissioning stage at this time. The Fugen, which is advanced thermal reactor operated by the Japan Nuclear Cycle Development Institute (JNC), was finally shutdown on March, 2003 after 25 years operation to be decommissioned. In addition, relating to planned unification between JAERI and JNC in 2005, the studies have been in progress on decommissioning and radioactive waste treatment and disposal; the cost was estimated to be 10 to 30 billion Japanese yens per year during 80 years for decommissioning of nearly 200 nuclear facilities. Decommissioning of nuclear facilities is thus getting to be one of important issues in Japan. Decommissioning of nuclear facilities might be possible using conventional and/or partially improved technology. However, reviewing project feedback experience on decommissioning and decontamination might contribute to solve various issues

    In fiscal 1987, the Atomic Energy Commission of Japan revised the 'Long term program for development and utilization of nuclear energy', which is done every five years. It determined the future direction of the research and development in JAERI. Three basic objectives are indicated in it, that is, to qualitatively upgrade nuclear technology, to tackle the frontiers of the technology, and to promote international collaboration. The new 'Long term task plan' of JAERI based on the 'Long term program' was established in August, 1987. The integral experiment on loss of coolant accident, the test on reactivity-initiated accident, the irradiation and post-irradiation examination of fuel, the development of safety analysis codes, the design and safety analysis of the Nuclear Fuel Cycle Safety Engineering Research Facility, the treatment and disposal of radioactive wastes, the preparatory work for constructing the High Temperature Engineering Test Reactor, the full scale plasma heating experiment with JT-60, the study on high efficiency confinement mode and current drive, the construction of the new home port for the nuclear ship 'Mutsu', the design of an advanced marine reactor, the reactor physics of FBRs and ATRs and other fundamental studies, and the operation of JRR-2, JRR-4 and JMTR are reported.

    The Regulatory Research Program should be seen as augmenting and extending the capability of in-house resources. The overall objective of the research program is to produce pertinent and independent information that will assist the Board and its staff in making correct, timely and credible decisions on regulating atomic energy. Within the framework of the general objective, the specific objectives are: (i) to verify information, claims or analyses from licensees in support of licensing actions; (ii) to fill gaps in knowledge to enable the Board to contribute to the establishment of health and safety requirements or guidelines or to aid in arriving at licensing decisions; (iii) to stimulate licensees to do more work on certain topics relating to health, safety or security; (iv) to develop information on the regulatory process and the evaluation of the regulatory process; (v) to develop equipment or procedures to enhance health, safety or security in those cases where the industry is not competent or inclined to do so; and (vi) to enhance the competence of the Board and its credibility in the eyes of licensees and the public

  8. Nuclear calculation for employing medium enrichment in reactors of Japan Atomic Energy Research Institute

    1979-01-01

    The fuel used for the research reactors of Japan Atomic Energy Research Institute (JAERI) is presently highly enriched uranium of 93%. However, the U.S. government (the supplier of fuel) is claiming to utilize low or medium enriched uranium from the viewpoint of resistivity to nuclear proliferation, and the availability of highly enriched uranium is becoming hard owing to the required procedure. This report is described on the results of nuclear calculation which is the basis of fuel design in the countermeasures to the reduction of enrichment. The basic conception in the reduction of enrichment is three-fold: to lower the latent potential of nuclear proliferation as far as possible, to hold the present reactor performance as far as possible, and to limit the reduction in the range which is not accompanied by the modification of reactor core construction and cooling system. This time, the increase of the density and thickness of fuel plates and the effect of enrichment change to 45% on reactivity and neutron flux were investigated. The fuel of UAl sub(x) - Al system was assumed, which was produced by powder metallurgical method. The results of investigations on JRR-2 and JMTR reactors revealed that 45% enriched fuel does not affect the performances much. However, deterioration of the performances is not neglegible if further reduction is needed. In future, the influence of the burn-up effect of fuel on the life of reactor cores must be investigated.

    Over the years, a large body of information has amassed which has helped to clarify the authors understanding of the complex chemistry occurring within chemical systems immediately following a nuclear reaction. With the increased knowledge of how reactive nuclides generated by such processes react chemically, it became increasingly apparent that the translational or recoil energy imparted to such species was not always the driving force behind some of the unusual chemistry seen in these systems. In many instances, the state of electronic excitation was found to strongly affect their chemistry. In others, the concomitant radiation chemistry often altered initial chemical states. Even so, with just a general understanding of how these effects work in unison, it has been possible in many instances to predict radiolabel distributions and yields in molecules. This ability has had an enormous impact in other fields utilizing radiotracers in research. This presentation will highlight specific examples in basic hot atom research which have focused on these problems, and describe general applications to other disciplines using radiotracers

    The simulation methods of different noises of atomic clocks are given. The frequency flicker noise of atomic clock is studied by using the Markov process theory. The method for estimating the maximum interval error of the frequency white noise is studied by using the Wiener process theory. Based on the operation of 9 cesium atomic clocks in the time frequency reference laboratory of NTSC (National Time Service Center), the noise coefficients of the power-law spectrum model are estimated, and the simulations are carried out according to the noise models. Finally, the maximum interval error estimates of the frequency white noises generated by the 9 cesium atomic clocks have been acquired.

    At the Tritium Laboratory Karlsruhe (TLK) laser Raman spectroscopy, gas chromatography, mass spectroscopy, calorimetry and ionisation chambers are used to determine the composition of tritium gas mixtures. For the first time a laser Raman experiment was assembled with an actively controlled resonator which yields a 50 times higher Raman signal and with all components (laser, optics, Raman cell and spectrometer) installed inside a glove box. Three gas chromatographs, each with up to six detectors, can determine the gases and their tritiated fractions expected in fusion devices down to the sub-ppm range. Tritium in solids, liquids and gases is determined by means of three calorimeters with a dynamic ranges of up to five orders of magnitude and a lower detection limit of 1 GBq. Since any of these techniques has its shortcomings the best analytical approach is to analyse a sample by more than one method

    The heavy ion accelerator UNILAC is well suited to experiments in the field of atomic physics because, with the aid of high-energy heavy ions atoms can be produced in exotic states - that is, heavy atoms with only a few electrons. Also, in close collisions of heavy ions (atomic number Z 1 ) and heavy target atoms (Z 2 ) short-lived quasi-atomic 'superheavy' systems will be formed - huge 'atoms', where the inner electrons are bound in the field of the combined charge Z 1 + Z 2 , which exceeds by far the charge of the known elements (Z <= 109). Those exotic or transient superheavy atoms delivered from the heavy ion accelerator make it possible to study for the first time in a terrestrial laboratory exotic, but fundamental, processes, which occur only inside stars. Some of the basic research carried out with the UNILAC is discussed. This includes investigation of highly charged heavy atoms with the beam-foil method, the spectroscopy of highly charged slow-recoil ions, atomic collision studies with highly ionised, decelerated ions and investigations of super-heavy quasi-atoms.

    Plutonium and 129 I are emitted from the Karlsruhe Reprocessing Plant (WAK) together with exhaust air and liquid effluents. Plutonium dispersion in the environment was used to calculate the dispersion factors, to determine the rates of deposition on grass and of the total deposition rates, to measure the distribution at depth of plutonium in the soil and to evaluate the contamination of plants and animals in the environment of the Karlsruhe Reprocessing Plant. The plutonium emissions with the liquid effluents were studied to deepen understanding of the process of sedimentation in a river system. Sediments, water samples, aerosols and living organisms from the Altrhein were examined. Factors of transfer to various organisms living in the Altrhein were measured. Most of the 129 I release from WAK goes via the exhaust air: this even applies after installation of an iodine filter into the exhaust air stack. The 129 I contamination of the environmental air, the soil, thyroids and milk was measured. Regarding the milk/air concentration ratio, a mean value of 210 was determined with a scattering range of 50 to 1480. Soil contamination was studied very thoroughly. Iodine-129 is transported into lower soil layers at a very slow rate only, if at all. The contamination of the soil with 129 I remained largely constant during the three years of investigations. The low rates of deposition of 0.02 to 0.05 cm/s indicate that 129 I is released to the environmental air again from plants undergoing the process of rotting. (author)

    The tandem accelerator in Japan Atomic Energy Research Institute was made by NEC in USA. Since it is the accelerator of turning-up structure, it has large magnet at the high voltage terminal, and supplies electric power by driving a generator with large diameter shaft. The control is carried out by CAMUCK, and the electronic circuit is protected from the surging arising due to discharge. Since the experiment on full scale was begun, 14 years have elapsed, and at present, it became a very stable accelerator. As to the operation mode, the acceleration voltage is limited to below 17 MV. The operation voltage and the state of operation are shown. Recently, the troubles of chains originating in oil have occurred. The adjustment of the tandem accelerator requires more than one month. The adjustment is mainly related to the chains and shafts, and this is explained. The ion source used for the tandem accelerator at present is the negative ion source made by NEC. The installation of an ECR ion source is planned. The utilization of the tandem accelerator system is reported. (K.I.)

    A major element of a system for nuclear material protection, control, and accounting (MPC and A) is to take the physical inventory of the nuclear material periodically. Physical inventory taking (PIT) includes ensuring that all nuclear material on inventory is included in the facility records and that the measured content of items or containers corresponds to the recorded values. A preliminary step to the conduct of the PIT is application of rapid inventory procedures that serve to provide the benchmark for the inventory, e.g., by identifying if any items are missing and also, if any unrecorded items are present. The Rapid Inventory approach is being implemented by the Research Institute for Atomic Reactors (RIAR) in Dimitrovgrad, Russia, as one of the first steps in the program to enhance nuclear materials safeguards at the site. This effort is being conducted under the US-Russian Cooperative Program on Nuclear Materials Protection.

    Aim of the present study is quantification of airborne pollutant dispersion potential in and around Bhabha Atomic Research Centre Trombay, a coastal belt of Arabian sea. Apart from synoptic atmospheric circulation, there is local land-sea interactive breezes diurnally in the area for which air mass ventilation potential is assessed here. For this purpose, a micro-meteorological station was established at Mandala hill top representing Trombay area to measure 3 dimensional wind components, i.e. Zonal: u, meridional: v and vertical: w, using ultrasonic anemometer. Hourly wind speed and wind direction are derived in this study for a period of 1 year, January-December 2013. Accuracy of wind components measurement is 0.1 m/s. This covers low wind condition too, i.e. wind speed below 1 m/s. Hourly statistics of year-long as well as seasonal period of wind field and associated parameters reveals the uniqueness of wind field phenomenon at the site being situated in west coast. Seasonal Wind Roses captures various frequencies of wind speed and wind direction for the respective periods

    Japan Atomic Energy Research Institute (JAERI) conducts Piping Reliability Proving Tests from 1975 to 1992 based upon the contracts between JAERI and Science and Technology Agency of Japan (STA) under the auspices of the special account law for electric power development promotion. The purpose of these tests are to prove the structural reliability of the primary cooling piping constituting a part of the pressure boundary in the light water reactor power plants. The tests with large experimental facilities had ended already in 1990. Presently piping reliability analysis by the probabilistic fracture mechanics method is being done. Until now annual reports concerning the proving tests were produced and submitted to STA, whereas this report summarizes the test results done during these 16 years. Objectives of the piping reliability proving tests are to prove that the primary piping of the light water reactor (1) be reliable throughout the service period, (2) have no possibility of rupture, (3) bring no detrimental influence on the surrounding instrumentations or equipments near the break location even if it ruptured suddenly. To attain these objectives (i) pipe fatigue tests, (ii) unstable pipe fracture tests, (iii) pipe rupture tests and also the analyses by computer codes were done. After carrying out these tests, it is verified that the piping is reliable throughout the service period. The authors of this report are T. Isozaki, K. Shibata, S. Ueda, R. Kurihara, K. Onizawa and A. Kohsaka. The parts they wrote are shown in contents. (author)

  6. The gratefulness of the entire nation: Atomic Energy Research Policy in Sweden 1945-1956

    Lindstroem, S.

    1991-01-01

    The dissertation is a study of the Swedish atomic energy research policy since its inception in the mid-1940's until the parliamentary decision in 1956 to launch the massive program of research and technological development which became known as the 'Swedish line'. This program entailed an effort to develop and introduce a nuclear technology based on domestically produced heavy water reactors and domestic energy supplies as a key component in a long-term solution to the nation's energy problem. The analysis is based on a study of government documents, parliamentary materials and public debates as well as extensive studies of the archives of both public agencies such as the Swedish State Power Board, private bodies such as the large-scale corporation ASEA and of the archives of the executive committee of the government party and of then-prime minister Tage Erlander. It has been possible to disaggregate the actual policy process into its constituent parts and, on the basis of such a close examination of the step-by-step process, to give an account which deviates considerably from many of traditional interpretations of both policy processes in general and of this period in modern Swedish political history in particular. Thus neither an exclusively rationalistic account in terms of the publicly stated objectives and reasons nor an account cast in terms of some of the more common metaphors in vogue such as 'iron triangles', 'segments' or 'issue networks' are able to capture the essence of this complex policy process. Rather an image emerges of a process of constant negotiation that takes place in a contested border-line zone between the public and the private sphere. It is also possible to relate this process to over-arching themes in modern Swedish politics such as the debate over rationalization and over the proper role of the state in the economic life of society.

    Periodic radiological survey and its analysis are useful on a two way approach. First, it will be used to generate baseline dose profile that will be prominently important during any radiological emergency. Secondly, due to some unforeseen human acts if orphan/abandoned radioactive source were present across Bhabha Atomic Research Centre site, the same can be detected and retrieved from the incident location. Periodic radiation survey of Bhabha Atomic Research Centre, Trombay site primarily validate/serve as an indicator of integrity of the various safety measures at the different nuclear fuel cycle facilities and on the prevailing radiological status at the vicinity of the facilities at Bhabha Atomic Research Centre, Trombay site. Radiation dose profile as a quality information has been accumulated in the last five years. Analysis of data has led to the conclusion that there has been no increase in hazard over the years though the quantum of radioactivity processed at the various facilities has undergone wide increase and radiation hazard at the site continues to be very negligible. Nuclear fuel cycle activities at Bhabha Atomic Research Centre do not pose any excess radiation risk at the site

    A suitable qualification for responsible personnel in Radiation Protection (RP) must be in general a combination of theoretical knowledge, and the ability (competency) to practice RP. While the theoretical knowledge is acquired by suitable education and by attending training courses, competency and skills can only be obtained by appropriate on-the-job training (OJT) followed by a period of work experience. From the feedback of questionnaires from 30 EU countries within the framework of the EU supported ENETRAP project it can be concluded that OJT provides better chances for future job opportunities and increases international flexibility. As result we recommend covering OJT together with education and training in the Basic Safety Standards and their guidelines for implementation. OJT should be specified by its content (syllabus, learning objectives), availability of necessary facilities and infrastructures as precondition for OJT, assessment of the competence of the participant, format of certificate, recognition of OJT, and responsibilities of host organisation and trainees. OJT should remain a key element in the remodelled 'European RP Training'. Based on these recommendations a two weeks training module on 'Occupational RP: Specificities of Waste Management and Decommissioning' designed for radiation protection professionals has been compiled at the Karlsruhe Training Centre FTU. While the first week of the pilot course focuses on the theoretical knowledge ranging from waste classification to decontamination techniques and transport of radioactive materials, the second week is addressed to practical training as OJT from clearance of radioactive waste, operative RP in the Decontamination Department to RP work in a Research Reactor under decommissioning. Special emphasis is devoted to RP aspects and active involvement of the participants in workshops and case studies. The results of the pilot run with participants from 8 different European countries are reported

    Atomic level spatial variability of electronic structure in Fe-based superconductor FeTe 0.55 Se 0.45 (T c = 15 K) is explored using current-imaging tunneling-spectroscopy. Multivariate statistical analysis of the data differentiates regions of dissimilar electronic behavior that can be identified with the segregation of chalcogen atoms, as well as boundaries between terminations and near neighbor interactions. Subsequent clustering analysis allows identification of the spatial localization of these dissimilar regions. Similar statistical analysis of modeled calculated density of states of chemically inhomogeneous FeTe 1−x Se x structures further confirms that the two types of chalcogens, i.e., Te and Se, can be identified by their electronic signature and differentiated by their local chemical environment. This approach allows detailed chemical discrimination of the scanning tunneling microscopy data including separation of atomic identities, proximity, and local configuration effects and can be universally applicable to chemically and electronically inhomogeneous surfaces

  19. Safety Culture Evaluation at Research Reactors of Pakistan Atomic Energy Commission

    International Nuclear Information System (INIS)

    Qamar, M.A.; Saeed, A.; Shah, J.H.

    2016-01-01

    The concept of safety culture was presented by IAEA in document INSAG-4 (1991), delineated as “assembly of characteristics and attitudes in organizations and individuals which establish that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance”. The purpose of this paper is to describe the evaluation of safety culture at research reactors of the Pakistan Atomic Energy Commission (PAEC). Evaluating the safety culture of a particular organization poses some challenges which can be resolved by using safety culture evaluation models like those of Sachein (1992) and Harber-Barrier(1998). In PAEC, safety culture is the integral part of management system which not only promotes safety culture throughout the organization but also enhances its significance. To strengthen the safety culture, PAEC is also participating in a number of international and regional meetings of IAEA regarding safety culture. PAEC and the national regulator Pakistan Nuclear Regulatory Authority (PNRA) are also arranging workshops, peer reviews, sharing operational experiences and interacting with IAEA missions to enhance its capabilities in the field of safety culture. The Directorate General of Safety (DOS) is a corporate office of PAEC for safety and regulatory matters. DOS is in the process of implementing a program to evaluate safety culture at nuclear installations of PAEC to ensure that safety culture is included as a vital segment of the Integral Management System of the establishment. In this regard, training sessions and lectures on safety culture evaluation are normally conducted in PAEC for awareness and enhancement of the safety culture program. Safety culture is also addressed in PNRA Regulations like PAK-909 and PAK-913. In this paper we will focus on the safety culture evaluation in our research reactors, i.e., PARR-1 and PARR-2. The evaluation results will be based on observations, interviews of employees, group discussions

  20. Epidemiological research on radiation-induced cancer in atomic bomb survivors

    International Nuclear Information System (INIS)

    Ozasa, Kotaro

    2016-01-01

    The late effects of exposure to atomic bomb radiation on cancer occurrence have been evaluated by epidemiological studies on three cohorts: a cohort of atomic bomb survivors (Life Span Study; LSS), survivors exposed in utero, and children of atomic bomb survivors (F 1 ). The risk of leukemia among the survivors increased remarkably in the early period after the bombings, especially among children. Increased risks of solid cancers have been evident since around 10 years after the bombings and are still present today. The LSS has clarified the dose–response relationships of radiation exposure and risk of various cancers, taking into account important risk modifiers such as sex, age at exposure, and attained age. Confounding by conventional risk factors including lifestyle differences is not considered substantial because people were non-selectively exposed to the atomic bomb radiation. Uncertainty in risk estimates at low-dose levels is thought to be derived from various sources, including different estimates of risk at background levels, uncertainty in dose estimates, residual confounding and interaction, strong risk factors, and exposure to residual radiation and/or medical radiation. The risk of cancer in subjects exposed in utero is similar to that in LSS subjects who were exposed in childhood. Regarding hereditary effects of radiation exposure, no increased risk of cancers associated with parental exposure to radiation have been observed in the F 1 cohort to date. In addition to biological and pathogenetic interpretations of the present results, epidemiological investigations using advanced technology should be used to further analyze these cohorts

    Instead of comminuting, U 3 Si 2 /U 3 Si powders are produced by atomizating directly from the molten alloys. Many benefits are introduced by applying the atomization technique: reduction of the process, homogeneous alloy composition within a particle and between particles, increase of the thermal conductivity and decrease of the chemical reactivity with aluminium due to particle's spherical shape.

  8. In-situ testing of HEPA filters in the nuclear Karlsruhe filter system

    International Nuclear Information System (INIS)

    Ohlmeyer, M.; Stotz, W.

    1977-01-01

    Nuclear plant operators and filter manufacturers are endeavouring to improve environmental protection by intensifying process control and/or improving filter quality. In-situ testing is an important element in these efforts since it represents a direct means of checking the success or otherwise of a particular development. The arrangements for in-situ testing should satisfy the following minimum requirements: the staff should not be exposed to risk during the test; the test method should be objective and reproducible as well as being as sensitive as possible; the test method should permit detection of individual leaks in the filter system so that they can be remedied as efficiently as possible; the test equipment should not necessitate modifications to the extract systems or plant construction; the test should be simple and capable of being carried out with a minimum of effort and equipment. GfK has developed the 'Nuclear-Karlsruhe' filter housing in accordance with these principles. This housing permits in-situ testing similar to the DIN 24184 visual oil-fog test or the DOP test. External visual checks on the general condition of the filter is also possible. A safe system of filter changing with a specially designed plastic bag attachment at an accessible height considerably increases the degree of protection of operating personnel

  9. Cancer risk among children of atomic bomb survivors. A review of RERF epidemiologic studies. Radiation Effects Research Foundation

    International Nuclear Information System (INIS)

    Yoshimoto, Y.

    1990-01-01

    This article summarizes recent epidemiologic studies of cancer risk among the children of atomic bomb survivors conducted at the Radiation Effects Research Foundation. These children include two groups: (1) the in utero-exposed children (ie, those born to mothers who had been pregnant at the time of the bombings of Hiroshima and Nagasaki) and (2) the F1 population, which was conceived after the atomic-bombings and born to parents of whom one or both were atomic bomb survivors. Although from 1950 to 1984 only 18 cancer cases were identified among the in utero sample, cancer risk did appear to significantly increase as maternal uterine dose increased. However, since the observed cases are too few in number to allow a site-specific review, the increased cancer risk cannot be definitively attributed to atomic bomb radiation, as yet. For those members of the F1 population who were less than 20 years old between 1946 and 1982, cancer risk did not appear to increase significantly as parental gonadal dose increased. Follow-up of this population will continue to determine if the patterns of adult-onset cancer are altered

  10. Time for atomic and molecular data bases is now (an overview of data management research at LLL)

    Hampel, V.E.; Henry, E.A.

    1977-01-01

    Two numerical data bases of atomic and molecular (A and M) data required for laser-induced fusion studies were created. One file contains primarily atomic energy levels and atomic transition data released by Charlotte E. Moore in NBS publications. The second file is based on the spectroscopic constants for more than 1000 molecular levels of approximately 160 heteronuclear diatomic molecules prepared by S. N. Suchard. Additional data bases are contemplated in support of the accelerating research activities in these fields. The present paucity of authenticated, computer-readable A and M data is not unlike that observed two decades ago in nuclear fission research. At that time, emphasis was also given to the accurate measurement of physical parameters and to reaction rates which eventually led to the ENDF/B series of evaluated neutron cross sections. Today, powerful computers have a more dominant role in modeling and predicting the results of promising experiments. Their effective use, however, depends more than ever before upon the availability of comprehensive and accurate files of A and M data. At the Lawrence Livermore Laboratory (LLL), these requirements are accentuated by the heavy reliance on computers. Also, trends are presently becoming apparent among users of the national computer network for Magnetic Fusion Energy, with its center at LLL, to coalesce organization-dependent data files into central data bases containing bibliographic information and numerical data as a common resource. The Data Management Research Project is collaborating with the National Bureau of Standards (NBS/NSRDS) to be able to respond to the emerging requirements. This should contribute to a ''Public Well'' of atomic and molecular data, unencumbered by legal or monetary constraints. 14 figures

    2015-02-01

    This is the second of two closely related articles (Paper I and Paper II) that together illustrate how research in physics education has helped guide the design of instruction that has proved effective in improving student understanding of atomic spectroscopy. Most of the more than 1000 students who participated in this four-year investigation were science majors enrolled in the introductory calculus-based physics course at the University of Washington (UW) in Seattle, WA, USA. The others included graduate and undergraduate teaching assistants at UW and physics majors in introductory and advanced physics courses at the University of Zagreb, Zagreb, Croatia. About half of the latter group were preservice high school physics teachers. Paper I describes how several conceptual and reasoning difficulties were identified among university students as they tried to relate a discrete line spectrum to the energy levels of atoms in a light source. This second article (Paper II) illustrates how findings from this research informed the development of a tutorial that led to improvement in student understanding of atomic emission spectra.

    Potential well formation due to space charge associated with spherically converging ion beams plays a key and essential role in the beam-beam colliding fusion, which is the major mechanism of the Inertial Electrostatic Confinement Fusion (IECF) devices. Many theoretical results so far predicted strongly localized potential well formation, and actually for the past 30 years, many experiments were dedicated to clarify this mechanism, but neither could provide definitive evidence. In this study, we succeeded for the first time in the world in observing the double-well potential profile by use of the laser-induced fluorescence method that makes use of Stark effects, which put a period to the controverse for 30 years on the existence of the double-well potential profile. Furthermore, aiming at demonstrating a numerical prediction of a strongly nonlinear dependence of the fusion reaction rate on the discharge current on negligence of the charge exchange processes, triple-grid auxiliary system was introduced in order to reduce the operating gas pressure, with a successful result of reducing the pressure down to 1/5 of the conventional one required for glow discharge with single-grid system. Also, we measured accelerated atoms' kinetic energies through Doppler shift spectroscopy, and found the maximum energy increases proportionally to the applied voltage, which implies an enhancement of the fusion reaction cross-section with an increasing applied voltage in the near future.

    Highlights: • Operation of a water detritiation facility under optimized conditions for high detritiation performances. • Improvement of operational procedures to process tritiated waste water. • Handling and reduction of tritiated waste water to achieve enriched low volume tritiated water for sufficient storage. • Demonstration of the efficient availability of the TRENTA WDS facility for technical scale operation. -- Abstract: A Water Detritiation System (WDS) is required for any Fusion machine in order to process tritiated waste water, which is accumulated in various subsystems during operation and maintenance. Regarding the European procurement packages for the ITER tritium fuel cycle, the WDS test facility TRENTA applying the Combined Electrolysis Catalytic Exchange (CECE) process was developed, installed and is currently in operation at the Tritium Laboratory Karlsruhe (TLK). Besides the on-going R and D work for the design of ITER WDS, the current status of the TRENTA facility provides the option to utilize the WDS for processing tritiated water. Therefore, in the framework of the EFDA JET Fusion Technology Work Programme 2011, the TLK was able to offer the capability on a representative scale to process tritiated water, which was produced during normal operation at JET. The task should demonstrate the availability of the CECE process to handle and detritiate the water in terms of tritium enrichment and volume reduction. The operational program comprised the processing of purified tritiated water from JET, with a total volume of 180 l and an activity of 74 GBq. The paper will give an introduction to the TRENTA WDS facility and an overview of the operational procedure regarding tritiated water reduction. Data concerning required operation time, decontamination and enrichment performances and different operating procedures will be presented as well. Finally, a preliminary study on a technical implementation of processing the entire stock of JET

    Waste Management Facilities, Trombay (WMFT) comprises Radioactive Solid waste Management Site (RSMS), an Effluent Treatment Plant (ETP), and a Decontamination Centre (DC). Radioactive wastes from the plants and laboratories in Mumbai are handled here. The wastes are categorized and classified as per International Atomic Energy Agency (IAEA) and Atomic Energy Regulatory Board (AERB) guidelines. RSMS is a near surface disposal facility, where assorted beta gamma solid waste is disposed off in appropriate disposal facilities. ETP is a centralized low level liquid waste treatment facility, where liquid effluent is chemically treated to remove the radionuclides present in it, monitored for radioactivity, and discharged into the Mumbai Harbour Bay. In DC, plant and laboratory used clothings and personnel protective wears are decontaminated, monitored and sent for reuse. A comprehensive radiation monitoring programme is in place in these facilities from the beginning of radioactive waste management operations at BARC. The per capita radiation dose of the occupational workers and individual maximum dose has been low. Radioactivity release through liquid effluent from ETP has been kept well below Authorized Limits (AL). There has been no safety related unusual occurrences during the facility operation, that had any significant radiological impact. (author)

    Progress on development of a lidar system for probing the upper atmosphere based on atomic oxygen resonance is presented and discussed. The promise of a fully-developed atomic oxygen lidar system, which must be based in space to measure the upper atmosphere, for yielding comprehensive new insights is discussed in terms of its potential to deliver global, height-resolved measurements of winds, temperature, and density at a high cadence. An overview of the system is given, and its measurement principles are described, including its use of 1) a two-photon transition to keep the optical depth low; 2) laser tuning to provide the Doppler information needed to measure winds; and 3) laser tuning to provide a Boltzmann temperature measurement. The current development status is presented with a focus on what has been done to demonstrate capability in the laboratory and its evolution to a funded sounding rocket investigation designed to make measurements of three-dimensional turbulence in the upper mesosphere and lower thermosphere.

    Electron stripping (ionization) cross sections for impurity (carbon) ions with various charge states in collisions with atomic hydrogens have been surveyed. It has been found that these data are relatively limited both in collision energy and charge state and, in particular those necessary for high energy neutral beam injection (NBI) heating in fusion plasma research are scarce. Some relevant cross sections for carbon ions, C q+ (q = 0-5) have been estimated, based upon the existing data, empirical behavior and electron impact ionization data. (author)

    When estimating the risks of oncogenesis and cancer mortality as a result of atomic bomb radiation exposure, medical X-ray doses received by the A-bomb survivors must also be estimated and considered. Using a phantom human, we estimated the X-ray doses received by A-bomb survivors during routine biennial medical examinations conducted at RERF as part of the long-term Adult Health Study (AHS), since these examinations may represent about 45 % of the survivors' total medical irradiations. Doses to the salivary glands, thyroid gland, lung, breast, stomach and colon were measured using thermoluminescent dosimeters. The results reported here will aid in estimating organ doses received by individual AHS participants. (author)

    The new specialized AFM-probes with hydroxyapatite structures for atomic force microscopy of heart tissues calcification were created and studied. A process of probe fabrication is demonstrated. The adhesive forces between specialized hydroxyapatite probe and endothelium/subendothelial layers were investigated. It was found that the adhesion forces are significantly higher for the subendothelial layers. We consider that it is connected with the formation and localization of hydroxyapatite in the area of subendothelial layers of heart tissues. In addition, the roughness analysis and structure visualization of the endothelial surface of the heart tissue were carried out. The results show high efficiency of created specialized probes at study a calcinations process of the aortic heart tissues.

    A study on improving the homogeneous dispersion of atomized spherical particles in fuel meats has been performed in connection with the development of high uranium density fuel. In comparing various mixing methods, the better homogeneity of the mixture could be obtained as in order of Spex mill, V-shape tumbler mixer, and off-axis rotating drum mixer. The Spex mill mixer required some laborious work because of its small capacity per batch. Trough optimizing the rotating speed parameter for the V-shape tumbler mixer, almost the same homogeneity as with the Spex mill could be obtained. The homogeneity of the extruded fuel meats appeared to improve through extrusion. All extruded fuel meats with U 3 Si powder of 50-volume % had fairly smooth surfaces. The homogeneity of fuel meats by V-shaped tumbler mixer revealed to be fairly good on micrographs. (author)

    Flow injection-hydride generation-atomic fluorescence spectrometry was a widely used method in the industries of health, environmental, geological and metallurgical fields for the merit of high sensitivity, wide measurement range and fast analytical speed. However, optimization of this method was too difficult as there exist so many parameters affecting the sensitivity and broadening. Generally, the optimal conditions were sought through several experiments. The present paper proposed a mathematical model between the parameters and sensitivity/broadening coefficients using the law of conservation of mass according to the characteristics of hydride chemical reaction and the composition of the system, which was proved to be accurate as comparing the theoretical simulation and experimental results through the test of arsanilic acid standard solution. Finally, this paper has put a relation map between the parameters and sensitivity/broadening coefficients, and summarized that GLS volume, carrier solution flow rate and sample loop volume were the most factors affecting sensitivity and broadening coefficients. Optimizing these three factors with this relation map, the relative sensitivity was advanced by 2.9 times and relative broadening was reduced by 0.76 times. This model can provide a theoretical guidance for the optimization of the experimental conditions.

    Earthquake Engineering and structural Dynamics has gained the attention of many researchers throughout the world and extensive research work is performed. Linear behaviour of structures, systems and components (SSCs) subjected to earthquake/dynamic loading is clearly understood. However, nonlinear behaviour of SSCs subjected to earthquake/dynamic loading need to be understood clearly and design methods need to be validated experimentally. In view of this, three major areas in earthquake engineering and structural dynamics identified for research includes: design and development of passive devices to control the seismic/dynamic response of SSCs, nonlinear behaviour of piping systems subjected to earthquake loading and nonlinear behavior of RCC structures under seismic excitation or dynamic loading. BARC has performed extensive work and also being continued in the above-identified areas. The work performed is helping for clearer understanding of nonlinear behavior of SSCs as well as in developing new schemes, methodologies and devices to control the earthquake response of SSCs.

    The Current Lead Test facility Karlsruhe (CuLTKa) is under construction at the Karlsruhe Institute of Technology (KIT) to perform acceptance tests of high temperature superconductor (HTS) current leads (CL). CuLTKa is in progress and present planning expects the completion in 2013. The data acquisition system is based on a modular design with electronic measurement and monitoring equipment covering a test voltage of 50 kV DC against ground. It provides plug-in units which enable temperature and voltage measurement at high voltage potential and in addition quench detection units which detect a loss of superconductivity reliably and quickly to avoid damage of the superconducting device under test. Prototype units for quench detection, temperature and voltage measurement have been successfully tested. Six temperature measurement units are already in use in the KIT test facility TOSKA and operated reliably during the acceptance tests of the HTS current leads for Wendelstein 7-X (W7-X) in 2011/2012. CuLTKa will be used first for 26 current leads which will be built in KIT for the fusion experiment JT-60SA. The present paper gives an overview of the design of the electronic measurement and quench detection equipment

    The Institute for Nuclear Solids Physics carried out about 90% of its work in the year of the report, 1993, on the main point of superconductivity. The work on high temperature superconductors on a cuprate basis was continued on a large scale. The availability of better samples (eg: non-twinned single crystals) make it possible to clear up a series of important detailed questions regarding the structure, grid dynamics and electronic structure. The activities closely related to applications of superconducting films were concentrated on the growth of a-axis and c-axis orientated films on technically relevant substrates (above all on sapphire, including suitable buffer layers and the examination of these films regarding their high frequency behaviour. Considerable progress was achieved in the manufacture of wafers coated on both sides. The work on Fullerene (carbon molecules C 60 , C 70 etc) and Fullerene compounds was continued. The Institute quickly succeeded not only in preparing these systems, but also in making a considerable contribution to a physical understanding of them. Among the Institute's activities, which are not directly connected to superconductivity (about 10%), one should mention above all, the experimental and theoretical work on the physics of surfaces and boundary surfaces, on polymer physics and on the physics of mesoscopic systems.

    At Tokai Research Establishment, JAERI, over one thousand people work in hot areas such as reactors, accelerators, chemical laboratories and waste treatment plants. The monitoring for internal contamination of this personnel is presented. Routine and special monitoring are carried out. The object of the former is to check for the presence of significant contamination, and that of the latter is to estimate body burden and committed dose equivalent, if necessary. Heavy shield and shadow shield whole body counters, a low energy lung counter and a wound monitor are used to detect the internal contamination due to γ or chi ray emitters, and bioassay technique is used for α or β emitters and uranium. The results of the monitoring until now are presented. (H.K.)

    Results are presented of internal contamination surveys carried out since 1969 at Tokai Research Establishment. Routine monitoring sometimes revealed significant internal contamination for tritium workers, but almost never for others. The number of subjects for special monitoring varied according to the activities. In 1965, the number of subjects for special monitoring was nearly 300, due to a reactor repair that year. In recent years, the number or special monitoring has been several tens or so. With regard to special monitoring, the workers with significant internal contamination were less than 50%. The internal dose (50 years) estimated for the majority of subjects was of mrem order. During the past 15 years, only several cases of exposure of rem order were found. The highest dose experienced was about 4 rems ( 131 I thyroid) (U.K.)

    IGCAR has developed the expertise and built comprehensive facilities to realize the mission programme of the Centre. The efforts would lead to achieving the world leadership and meet the expectation and aspiration of the nation for ensuring energy security. Taking into consideration the enhanced role FBRs are likely to play in contributing to the nuclear power component of the nation, there is a need to augment skilled manpower for the critical assignments to take up challenges in the design of plant, development of equipment and processes. Thus human resource development has been one of the areas of emphasis in the management philosophy of the Centre. Initiating the Training School programme at Kalpakkam, identifying research scholars to take up the problems in interface areas for achieving breakthroughs, attracting young people and empowering them has been the 'mantra' adopted at the Centre. Multilevel mentoring process has been built in and mentoring the young talent has been our priority. In this paper, we discuss our approach to overall human resource development at our Centre

    2011-01-01

    Work with individual atoms and molecules aims to demonstrate that miniaturized electronic, optical, magnetic, and mechanical devices can operate ultimately even at the level of a single atom or molecule. As such, atomic and molecular manipulation has played an emblematic role in the development of the field of nanoscience. New methods based on the use of the scanning tunnelling microscope (STM) have been developed to characterize and manipulate all the degrees of freedom of individual atoms and molecules with an unprecedented precision. In the meantime, new concepts have emerged to design molecules and substrates having specific optical, mechanical and electronic functions, thus opening the way to the fabrication of real nano-machines. Manipulation of individual atoms and molecules has also opened up completely new areas of research and knowledge, raising fundamental questions of "Optics at the atomic scale", "Mechanics at the atomic scale", Electronics at the atomic scale", "Quantum physics at the atomic sca...

    Determination of 239 , 240 Pu and 241 Am in the Cisadane river sediment and surface soil samples collected in 1996 from the environment of Atomic Energy Research Establishment (PPT A) of Serpong has been carried out. The objective of research was to evaluate the existence of 239 , 240 Pu and 241 Am in the environment as impact of nuclear activities in the PPT A Serpong. Surface soils were collected from 3 locations and each of location consists of 4 sampling sites. Cisadane river sediment consists of 3 sampling sites. The results showed that the average concentration were founded to be 17.03 ± 2.49 mBq/kg for 239 , 240 Pu and 9.20 ± 2.93 mBq/kg for 241 Am. The observed 239 , 240 Pu 241 Am concentration are low compared to the reported values for some other areas of the world. The Activity ratios of 241 Am/ 239 , 24O Pu and 239 , 240 PU/ 137 Cs in surface soils were found to be in the narrow range 0.32 to 0.53 with a mean value of 0.43 ± 0.09 and 0.017 to 0.029 with a mean value of 0.024 ± 0.005 respectively. This ratio is in excellent agreement with the value of global fallout

    Japan Atomic Energy Research Institute(JAERI) conducted Piping Reliability Proving Tests from 1975 to 1992 based upon the contracts between JAERI and Science and Technology Agency of Japan under the auspices of the special account law for electric power development promotion. The purposes of those tests are to prove the structural reliability of the primary cooling piping constituting a part of the pressure boundary in the water reactor power plants. The tests with large experimental facilities had ended already in 1990. After that piping reliability analysis by the probabilistic method followed until 1992. This report describes the users manual on databases about the test results using the large experimental facilities. Objectives of the piping reliability proving tests are to prove that the primary piping of the water reactor (1) be reliable throughout the service period, (2) have no possibility of rupture, (3) bring no detrimental influence on the surrounding instrumentations or equipments near the break location. The research activities using large scale piping test facilities are described. The present report does the database about the test results pairing the former report. With these two reports, all the feature of Piping Reliability Proving Tests is made clear. Briefings of the tests are described also written in Japanese or English. (author)

Our teams have investigated the stability of the surface (the heliopause) that separates the solar wind from the local interstellar medium, the transport of galactic cosmic rays, the properties of the heliotail flow, and modifications to the bow wave in front of the heliopause due to charge exchange between the neutral H atoms born in the solar wind and interstellar ions. Modeling results have been validated against observational data, such as obtained by the Interstellar Boundary Explorer (IBEX), and made it possible to shed light on the structure of energetic neutral atom maps created by this spacecraft.. We have also demonstrated that charge-exchange modulated heliosphere is a source of anisotropy of the multi-TeV cosmic ray flux observed in a number of Earth-bound air shower experiments. Newly developed codes are implemented within a Multi-Scale Fluid-Kinetic Simulation Suite (MS-FLUKSS), a publicly available code being developed by our team for over 12 years. MS-FLUKSS scales well up to 160,000 computing cores and has been ported on major supercomputers in the country. Efficient parallelization and data choreography in the continuum simulation modules are provided by Chombo, an adaptive mesh refinement framework managed by Phillip Colella's team at LBNL. We have implemented in-house, hybrid (MPI+OpenMP) parallelization of the kinetic modules that solve the Boltzmann equation with a Monte Carlo method. Currently, the kinetic modules are being rewritten to take advantage of the modern CPU-GPU supercomputer architecture.

    2005-09-01

    The fabrication of uranium-plutonium oxide fuel started in Forschungszentrum Karlsruhe and at ALKEM company to begin for the criticality experiments in the SNEAK reactor and subsequently for stationary fuel pin irradiations in the FR2, BR2, DFR, Rapsodie, Phenix and KNK II reactors. The production methods comprised first the mechanical blending of UO2 and PuO2 followed by direct pressing and sintering of the pellets, later the advanced methods such as optimized comilling and ammonium uranyl plutonyl coprecititation. The fabrication of pellets was described in the main, further the alternative fuel pin manufacturing processes by vibrational compaction and hot-impact densification were discussed. The first capsule and pin irradiations in the FR2 and BR2 reactors contributed to the assessment of the maximum operation parameters within the fuel pin development such as linear heat rating, cladding temperature and burnup. Subsequently, small-bundle and largebundle irradiations were made in fast reactors in cooperation with Interatom company in order to verify the specifications for the commercial fast reactor SNR 300. Milestones were the maximum burnup of 175 GWd/t metal, corresponding 18.6 % of the heavy atoms, obtained in one of the KNK II fuel pin assemblies, and the displacement rates in the cladding materials of 140 dpa NRT attained in the Phenix reactor. Higher implications gained later the stationary irradiations of defected mixed-oxide pins, the mild fuel pin transient operations, the local blockage experiments and the severe hypothetic accidents in the respective Siloe, HFR, BR2 and CABRI reactors. These experiments were made solely in international partnership. Further activities were the chemical analyses of solid residues and coprecipitations of irradiated mixed-oxide fuels in the head-end of the reprocessing. All these actions were coordinated in the then fast breeder project. Furthermore, irradiated fuels and fuel pins of other reactor types were

    The advanced spent fuel conditioning process facility (ACPF) of the irradiated materials examination facility (IMEF) at the Korea Atomic Energy Research Institute (KAERI) has been renovated to implement a lab scale electrolytic reduction process for pyroprocessing. The interior and exterior structures of the ACPF hot cell have been modified under the current renovation project for the experimentation of the electrolytic reduction process using spent nuclear fuel. The most important aspect of this renovation was the installation of the argon compartment within the hot cell. For the design and system implementation of the argon compartment system, a full-scale mock-up test and a three-dimensional (3D) simulation test were conducted in advance. The remodeling and repairing of the process cell (M8a), the maintenance cell (M8b), the isolation room, and their utilities were also planned through this simulation to accommodate the designed argon compartment system. Based on the considered refurbishment workflow, previous equipment in the M8 cell, including vessels and pipes, were removed and disposed of successfully after a zoning smear survey and decontamination, and new equipment with advanced functions and specifications were installed in the hot cell. Finally, the operating area and isolation room were also refurbished to meet the requirements of the improved hot cell facility.

    The Japan Atomic Energy Research Institute has been proposing the Neutron Science Project (NSP). The NSP requires pulse and CW proton beams with an energy of 1.5 GeV and an average beam power up to 8MW. This paper describes design concepts and parameters of the linac. A front end part of the linac, which consists of RFQ, DTL and SDTL sections, uses normal conducting structures and a high energy part uses superconducting (SC) structures. The linac has two injector lines for the pulse and the CW modes, respectively, and the two lines merge at 7 MeV. The total linac length is approximately 900 m and most of the part (>75%) is the superconducting section. An equipartitioning design, which is a new idea to suppress an emittance growth for high power linacs, has been taken for the DTL, the SDTL and the SC sections. Compared with the conventional constant phase advance design scheme, the equipartitioning design scheme is proved to be a good approach to suppress the longitudinal emittance growth. (author)

    Joint Nordic research programmes in nuclear safety have been conducted since 1977 under the direction of the Nordic Liaison Committee for Atomic Energy. Each of these four-year programmes is evaluated according to a procedure established by the Nordic Committee for Safety Research, NKS. The latest programme covered the period 1985-89 and included items that are of interest to countries that have nuclear power plants (Finland and Sweden) as well as to countries without (Denmark, Iceland and Norway). This last programme has been evaluated in 1990. The first area (AKT) deals with phenomena that might occur within the reactor containment during accidents. It also deals with potential pathways of radioactive material that could be released, as well as effects in the environment and possible counter-measures. The second area (KAV) investigates several topics related to waste management, such as waste arising in Scandinavia from power plant operation and decommissioning, and related transportation needs. It also deals with the methods used for modelling possible leaks from waste repositories and the uncertainty related to such calculations. The third area (RAS) deals with risk management - how decisions on safety issues are made, and what is the relative risk of nuclear activities. It also deals with methods for safety calculations that are based on a probabilistic approach. In the fourth area (MAT), the tendency of materials to develop cracks under tough external conditions is examined together with corrosion issues relevant to nuclear plants. Finally, the fifth area (INF) deals with the possibility of using modern information technology to support communication and decision making during emergency situations at compelx industrial plants.

    Following the atomic bomb attacks on Japan in 1945, scientists from the United States and Japan joined together to study the Hibakusha - the bomb affected people in what was advertised as a bipartisan and cooperative effort. In reality, despite the best efforts of some very dedicated and earnest scientists, the early years of the collaboration were characterized by political friction, censorship, controversy, tension, hostility, and racism. The 70-year history, scientific output and cultural impact of the Atomic Bomb Casualty Commission and the Radiation Effects Research Foundation are described in the context of the development of Occupied Japan.

    We report optimized auxiliary basis sets for use with the Karlsruhe segmented contracted basis sets including moderately diffuse basis functions (Rappoport and Furche, J. Chem. Phys., 2010, 133, 134105) in resolution-of-the-identity (RI) post-self-consistent field (post-SCF) computations for the elements H-Rn (except lanthanides). The errors of the RI approximation using optimized auxiliary basis sets are analyzed on a comprehensive test set of molecules containing the most common oxidation states of each element and do not exceed those of the corresponding unaugmented basis sets. During these studies an unsatisfying performance of the def2-SVP and def2-QZVPP auxiliary basis sets for Barium was found and improved sets are provided. We establish the versatility of the def2-SVPD, def2-TZVPPD, and def2-QZVPPD basis sets for RI-MP2 and RI-CC (coupled-cluster) energy and property calculations. The influence of diffuse basis functions on correlation energy, basis set superposition error, atomic electron affinity, dipole moments, and computational timings is evaluated at different levels of theory using benchmark sets and showcase examples.

  11. Report of evaluation on socio-economic effects of R and D results in Japan Atomic Energy Research Institute (JAERI)

    International Nuclear Information System (INIS)

    2002-08-01

    Japan Atomic Energy Research Institute (JAERI), as a core organization devoted to comprehensive nuclear energy research, has steadily promoted nuclear energy research aiming at long-term and stable supply of energy supporting the basis of national existence, advanced nuclear science and engineering leading to increase in Japanese industrial competitive power, etc. Through these undertaking, JAERI has produced a lot of remarkable achievements to contribute the national requests mentioned above. In total, about 1.8 trillion-yen of national funds and over 60,000 person · years of researchers and technical staffs have been invested in the R and D's for the past 45 years. Recently it has been argued and recognized to evaluate how the profits of R and D results in public research institutes supported by national funds are returned to the Japanese people as taxpayers and society as part of an administrative and financial reform. Then, seeing its 45th anniversary, JAERI has tried to evaluate the effects of the R and D achievements on the Japanese society and economy apart from the reviews on the management of the organization and research results by the ex-house experts from the viewpoints of specialty and technical aspects. In order to execute the aforementioned evaluation, JAERI established the in-house Ad hoc Committee for Evaluation of R and D Achievements where decision of the evaluation plan is made, in July 2001, and executed the evaluation followed by assembling the necessary database collected from individual branches. Results obtained from these activities were finally summarized in the Ad hoc Committee. Because a methodology for quantitative evaluation of the economical effects, i.e. cost-benefit effects of R and D's was not established yet, the evaluation was prudently carried out with the assistance of three think tanks and under advices by three ex-house experts. R and D's in JAERI are not limited to the ones where benefits corresponding to profits can be

    Atom optics, in analogy to neutron and electron optics, deals with the realization of as a traditional elements, such as lenes, mirrors, beam splitters and atom interferometers, as well as a new 'dissipative' elements such as a slower and a cooler, which have no analogy in an another types of optics. Atom optics made the development of atom interferometer with high sensitivity for measurement of acceleration and rotational possible. The practical interest in atom optics lies in the opportunities to create atom microprobe with atom-size resolution and minimum damage of investigated objects. (Cho, G. S.)

  14. Evaluation of socio-economic effects of R and D results at Japan Atomic Energy Research Institute. 2. Socio-economic evaluation of the basic research at JAERI

    International Nuclear Information System (INIS)

    2003-11-01

    The Japan Atomic Energy Research Institute (JAERI), as a core organization devoted to comprehensive nuclear energy research, has steadily promoted various types of research and development (R and D) studies since its establishment in June 1956. Research activities are aimed at performing (1) R and D for nuclear energy, (2) the utilization and application of radiation-based technologies, and (3) the establishment of basic and fundamental research in the nuclear field. Last year, the socio-economic effects on items (1) and (2) were qualitatively and quantitatively evaluated. The quantitative evaluation of item (3) from the viewpoint of a socio-economic effect, however, calls for a different concept and methodology than previously used cost-benefit approach. Achievements obtained from the activities conducted over the last 10 years implied that socio-economics in basic research funded by the public could contribute to the (1) increase in useful intellectual stocks, (2) upbringing of highly skilled college graduates, (3) construction of new scientific facilities and creation of methodologies, (4) stimulation and promotion of social interrelations by networking, (5) increase of one's ability to solve scientific problems, and (6) establishment of venture companies. In this study, we focused on item (4) for the analysis because it assumed that the external economic effect has a link with the socio-economic effects accompanying the networking formation. For the criteria of socio-economic effects we assume that the external effect becomes significant in proportion to the width of networking and/or the magnitude of cooperation measured by numbers of co-writing studies between JAERI and the research bodies, namely private and governmental sectors and universities. Taking these criteria into consideration, the subsequent four items are prepared for quantitative study. They are (1) to clarify the basic research fields where JAERI has been established a significant effort to

    Several sections of HAWC glass rods remaining at the end of glass pouring at the Karlsruhe Vitrification Plant (VEK) were retained during vitrification operation in 2009-2010 and transferred to the KIT-INE shielded box line for later glass product characterization. A mm sized fragment with a contact dose rate of ∼590 μSv/h was selected for pilot XAS/XRF investigations at the INE-Beamline for actinide science at the ANKA synchrotron radiation source. The experiment was aimed at elucidating the potential of direct radionuclide speciation with an emphasis on the fission products Se and Tc in highly active nuclear materials and at assessing the possible influence of the γ-radiation field surrounding highly active samples on the beamline instrumentation. While the influence of γ-radiation turned out to be negligible, initial radionuclide speciation studies by XAFS were most promising. In addition to Se and Tc speciation, the focus of these initial investigations was on the possibility for direct actinide speciation by recording corresponding L3-edge XAFS data. The registration of high quality XANES data was possible for the actinide elements U, Np, Pu and Am, as well as for Zr.

    The measurements of wind direction and wind velocity performed at 60 m and 200 m height were evaluated for one year each and frequency distributions of the measured values were established. The velocity was divided into 1 m/s steps and the direction into 10 0 sectors. The frequency distribution of the wind direction reveals three maxima located in the southwest, northeast and north, respectively. The maximum of the frequency distribution of the wind velocity occurs between 4 and 5 m/s at 200 m height and between 3 and 4 m/s at 60 m height. (orig.) [de

    The two on-line monitoring systems used in KfK environmental monitoring should be taken as measures of accident precaution and they are restricted to measurement of gamma local dose rates and of the (β + γ)-radiation levels. One of the systems serves to monitor the KfK operational area, the second serves to monitor the surrounding communities up to a radius of 8 km. By use of two different types of detectors the first system covers a range of measurement of 10 μrem/h to 1000 rem/h. By the second system only increases in the radiation level can be detected. It allows to record accidents in which countermeasures must be taken very urgently. The two monitoring systems are described which have been operated and partly been developed at the KfK. The possibilities and limits of using them for environmental monitoring are discussed. (orig./HP) [de

    The multipurpose reactor MZFR was a pressurized water reactor, cooled and moderated with heavy water. It was built from 1961 to 1966, and went critical for the first time on 29 September 1965. After 19 years of successful operation, the reactor was shut down on 3 May 1984. The reactor had a thermal output of 200 MW, and an electrical output of 50 MW. In addition to generating electricity, the MZFR had the following functions: - Testing fuel assemblies and various materials for reactor construction; - Gaining experience in the design, erection and operation of heavy water reactor systems; - Training scientific and technical reactor personnel; - Providing heat (first nuclear combined heat and power system (1979-1984)). In 1989, it was decided to dismantle the reactor completely, step by step. The decommissioning concept for the plant, down to a greenfield site, provides for eight distinct decommissioning steps (phases). A separate decommissioning licence was required for each step. The decommissioning work was carried out according to pre-approved work schedules. About 72 000 t of concrete and 7200 t of metal were to be removed. About 1000 t of concrete (500 t biological shield) and 1680 t of metal were to be classified as radioactive waste.

    Atomic manipulation using a scanning tunneling microscope (STM) tip enables the construction of quantum structures on an atom-by-atom basis, as well as the investigation of the electronic and dynamical properties of individual atoms on a one-atom-at-a-time basis. An STM is not only an instrument that is used to ‘see’ individual atoms by means of imaging, but is also a tool that is used to ‘touch’ and ‘take’ the atoms, or to ‘hear’ their movements. Therefore, the STM can be considered as the ‘eyes’, ‘hands’ and ‘ears’ of the scientists, connecting our macroscopic world to the exciting atomic world. In this article, various STM atom manipulation schemes and their example applications are described. The future directions of atomic level assembly on surfaces using scanning probe tips are also discussed. (review article)

    This paper reports the achievements in fiscal 1998 on the 'research and development of an ultimate atom and molecule manipulation technology' having been performed by the concentrated research institution established jointly with the National Institute for Advanced Inter-disciplinary Research of the Agency of Industrial Science and Technology, referred to as the 'atom-technology research body'. In improving the calculation methods, development has been launched on a method capable of executing calculations in more realistic time period, substituting the Green function method that consumes a huge amount of time. The research trend survey was performed by visiting and participating with various organizations and academic societies in America and Britain. Development was attempted on a small spin detector for use in a spin polarization scanning electron microscope for high-resolution magnetized section observation. In the development, investigation was made on the relationship between accelerated voltage and the spin detector to obtain the detection efficiency equivalent to or better than that of the conventional mott-spin detector, while aiming at reducing the operation voltage and reducing the dimensions. As a result, it was disclosed that sufficient efficiency may be obtained if such a condition as thickness of the thin gold film is adjusted even at low accelerated voltage. In addition, with an objective to reduce the operation voltage of the small spin detector, an MCP was employed in the detector. (NEDO)

    The atomic dipole polarizability governs the first-order response of an atom to an applied electric field. Atomic polarization phenomena impinge upon a number of areas and processes in physics and have been the subject of considerable interest and heightened importance in recent years. In this paper, we will summarize some of the recent applications of atomic polarizability studies. A summary of results for polarizabilities of noble gases, monovalent, and divalent atoms is given. The development of the CI+all-order method that combines configuration interaction and linearized coupled-cluster approaches is discussed.

    Research on the intermetallic compounds of uranium was revived in 1978 with the decision by the international research reactor community to develop proliferation-resistant fuels. The reduction of 93% 235 U (HEU) to 20% 235 U (LEU) necessitates the use of higher U-loading fuels to accommodate the addition 238 U in the LEU fuels. While the vast majority of reactors can be satisfied with U 3 Si 2 -Al dispersion fuel, several high performance reactors require high loadings of up to 8-9 g U cm -3 . Consequently, in the renewed fuel development program of the Reduced Enrichment for Research and Test Reactors (RERTR) Program, attention has shifted to high density uranium alloys. Early irradiation experiments with uranium alloys showed promise of acceptable irradiation behavior, if these alloys can be maintained in their cubic γ-U crystal structure. It has been reported that high density atomized U-Mo powders prepared by rapid cooling have metastable isotropic γ-U phase saturated with molybdenum, and good γ-U phase stability, especially in U-10wt.%Mo alloy fuel. If the alloy has good thermal compatibility with aluminium, and this metastable gamma phase can be maintained during irradiation, U-Mo alloy would be a prime candidate for dispersion fuel for research reactors. In this paper, U-2w.%Mo and U-10w.%Mo alloy powder which have high density (above 15 g-U/cm 3 ), are prepared by centrifugal atomization. The U-Mo alloy fuel meats are made into rods extruding the atomized powders. The characteristics related to the thermal compatibility of U-2w.%Mo and U-10w.%Mo alloy fuel meat at 400 o C for time up to 2000 hours are examined. (author)

    There is a need for accurate dosimetry for studies of health effects in the Japanese atomic bomb survivors because of the important role that these studies play in worldwide radiation protection standards. International experts have developed dosimetry systems, such as the Dosimetry System 2002 (DS02), which assess the initial radiation exposure to gamma rays and neutrons but only briefly consider the possibility of some minimal contribution to the total body dose by residual radiation exposure. In recognition of the need for an up-to-date review of the topic of residual radiation exposure in Hiroshima and Nagasaki, recently reported studies were reviewed at a technical session at the 57th Annual Meeting of the Health Physics Society in Sacramento, California, 22-26 July 2012. A one-day workshop was also held to provide time for detailed discussion of these newer studies and to evaluate their potential use in clarifying the residual radiation exposures to the atomic-bomb survivors at Hiroshima and Nagasaki. Suggestions for possible future studies are also included in this workshop report.

Among the wide range of materials developed for specific functions under rigorous conditions are nuclear pure grade uranium, zirconium and beryllium, and conventional materials like aluminium, carbon steel and stainless steels. Radioisotopes are produced and used for tracer studies in various fields. Various types of nuclear gauges and nuclear instruments are produced. Radiations have been used to develop new high yielding groundnut mutants with large kernals. The sterile male technique for pest control and radiosterilization technique to process potatoes, onions and marine foods for storage are ready for exploitation. Processes and equipment have been developed for production of electrolytic hydrogen, electrothermal phosphorus and desalinated water. Indigenously manufactured components and materials are now being used for the nuclear energy programme. Indian nuclear power programme strategy is to build heavy water reactors and to utilise their byproduct plutonium and depleted uranium to feed fast breeder reactors which will produce more fissile material than burnt. Finally a special mention has been made of the manpower development programme of the BARC. BARC has established a training school in 1957 giving advanced training in physics, chemistry and various branches of engineering and metallurgy

    Bodnarczuk, M.

    1994-06-01

    The objective of the International Atomic Energy Agency (IAEA) Guidelines on Quality Assurance for R&D is to provide guidance for developing quality assurance (QA) programs for R&D work on items, services, and processes important to safety, and to support the siting, design, construction, commissioning, operation, and decommissioning of nuclear facilities. The standard approach to writing papers describing new quality guidelines documents is to present a descriptive overview of the contents of the document. I will depart from this approach. Instead, I will first discuss a conceptual framework of metrics for evaluating and improving basic and applied experimental science as well as the associated role that quality management should play in understanding and implementing these metrics. I will conclude by evaluating how well the IAEA document addresses the metrics from this conceptual framework and the broader principles of quality management.

    Full Text Available Atmospheric pressure spatial atomic layer deposition (AP-SALD has recently emerged as an appealing technique for rapidly producing high quality oxides. Here, we focus on the use of AP-SALD to deposit functional ZnO thin films, particularly on the reactors used, the film properties, and the dopants that have been studied. We highlight how these films are advantageous for the performance of solar cells, organometal halide perovskite light emitting diodes, and thin-film transistors. Future AP-SALD technology will enable the commercial processing of thin films over large areas on a sheet-to-sheet and roll-to-roll basis, with new reactor designs emerging for flexible plastic and paper electronics.

  9. Health effects of low-dose radiation on atomic workers: a case study of employer-directed research

    Sterling, T.D.

    1980-01-01

    The 15-year history of a study on the health effects of low-dose radiation on workers at the Hanford Atomic Plant in Washington State demonstrates different facets of political control by employers over investigations of employee working conditions. Evidence obtained through the Freedom of Information Act shows that the original study, under the guidance of Dr. Thomas Mancuso, an experienced and respected occupational health epidemiologist, was proof to employees that their exposure levels were safe. When it turned out that the study might show an increase in cancer rates among plant employees, its control was transferred to the employer. Lessons from these events are that it may be necessary for organized labor to negotiate the conduct of occupational health investigations as part of negotiated settlements

  10. Visualization research on spray atomization, evaporation and combustion processes of ethanol–diesel blend under LTC conditions

    Highlights: • Spray combustion of E20 diesel in LTC condition shows a U-shape flame structure. • The chasing behavior of fuel spray exists near the spray axis. • Fuel ignition doesn’t initiate at the spray tip but in peripheral regions behind it. • An improper chamber structure may lead to a long post-combustion duration. - Abstract: Utilization of ethanol in diesel engines has been widely studied by means of engine experiments and emission detection. However, pertinent studies on the spray combustion process of ethanol–diesel blends are scarce. In order to verify the effect of ethanol in modern diesel engines, an experiment is conducted to visualize the spray combustion process of ethanol–diesel blend under LTC conditions. Stages including atomization, evaporation and combustion, are investigated individually to realize synergistic analysis. Meanwhile, considering the long time scale of combustion after fuel injection finishes, characteristics during and after injection period are both targeted in this paper. Moreover, measurement of macroscopic characteristics, such as spray tip penetration, spray spreading cone angle and flame lift off length, provides a quantitative profile of the spray structure. Results show that, evaporation, different from atomization, has little influence on spray penetration, but promotes the spray spreading angle and spray projected area. So does combustion, which enlarges the spray projected area further. Ignition takes place on the periphery behind the spray tip, then quickly extends to the whole head of the spray and forms a U-shape diffusion structure. After the injection period, the residual spray tail develops into wavelike structures due to absence of subsequent entrainment force. Also, the penetration speed falls greatly to an extent much slower than flame propagation, which frees the flame from the lift-off effect. Subsequently, the flame propagates upstream towards the nozzle orifice. After consumed all fuel in

    1977-02-01

    Fro, 23,7,1976 to 28.7.76 and from 8.3.76 to 9.16.76 50 pCi 131 I/m 3 , 116 pCi 133 I/m 3 und 195 pCi 135 I/m 3 were measured on an average in 11 samples of waste air from the Karlsruhe Nuclear Fuel Reprocessing Plant (WAK). During these time intervals no dissolution of fuel material was performed. From 16.9.76 to 27.10.76 18 charges of nuclear fuel were dissolved. During this period 3.3 pCi 131 I/m 3 and 7.9 pCi 133 I/m 3 were obtained as mean waste air concentrations which were higher than the lower detection limit of the method of measurement used. 244 Cm, 242 Cm, 242 Pu, 240 Pu and 238 Pu are responsible for the production of radioiodine in nuclear fuel by spontaneous fission. 244 Cm is the most important nuclide in highly active waste solutions (HAL). The cumulative fission yield is well approximated by 3% for 13 I and by 6% for 133 I. The radioiodine is set free during fuel dissolution by venting of tanks and HAL pipes and during the vritification of such solutions. The radioiodine produced by spontaneous fission is released from WAK only by venting of tanks and HAL pipes. Corresponding to the conditions of venting, air concentrations as high as 4.4 pCi 131 I/m 3 and 8.2 pCi 133 I/m 3 are expected. These concentrations agree well with air concentrations measured during the period of fuel dissolution. Based on plausible assumptions the 131 I and 133 I waste air concentrations for the period of outage are calculated from an evaporated volume of HAL in the pipes corresponding to about 10 g of 244 Cm and with 40% equilibrium between I 2 in evaporated HAL and in waste air. In the worst case 131 I-concentrations in the waste air of WAK result in an annual release of 0.2 mCi 131 I. This value is less than 1% of the authorized annual releases of 1976. For a reprocessing plant of 1,400 t/a capacity the annual expected release of 131 I lies in the mCi range. (orig.) [de
