The Cadarache Nuclear Studies Centre is located in a thinly populated region. Covering a total area of 1600 hectares, it has been able to accommodate numerous and important research facilities. In 1970, 11 reactors or critical assemblies were in operation. More than 164000 m 2 are devoted to laboratories, testing areas, installations for the inspection of irradiated fuel elements and plutonium technology workshops. Up to 1968 the low- and intermediate-activity solid wastes (categories 1, 2 and 30) collected at the Centre were divided into two classes for disposal purposes: (a) burnable wastes which, after sorting, were destroyed in an incinerator; (b) compressible wastes which were compacted in concrete containers after recovery of the packing, by means of a 250-ton press. The situation at Cadarache and the results obtained in hydrogeological studies have prompted the Centre to improve the processing of these wastes and reduce the cost. The treatment of solid wastes should, in effect, be regarded as a step towards their final elimination. The measure envisaged at Cadarache were thus aimed at permitting final storage on site, in order to reduce the volume of waste, contain the activity and keep the cost to a minimum. The management of solid wastes is at present based on the following methods: (a) storage in trenches with PVC packing for non-burnable solid wastes of categories 1 and 4, after monitoring of specific activities; (b) compacting and storage in leak-proof pools for solid wastes of categories 2 and 3, the most highly active undergoing a period of decay storage beforehand; (c) incineration of burnable solid wastes of categories 1 and 2 and also of contaminated oils and solvents.

Dose assessment for Greifswald and Cadarache

International Nuclear Information System (INIS)

Raskob, W.

1996-07-01

Probabilistic dose assessments for accidental atmospheric releases of tritium and activation products as well as releases under normal operation conditions were performed for the sites of Greifswald, Germany, and Cadarache, France. Additionally, aquatic releases were considered for both sites. No country specific rules were applied and the input parameters were adapted as far as possible to those used within former ITER studies to have a better comparison to site independent dose assessments performed in the frame of ITER. The main goal was to complete the generic data base with site specific values. The agreement between the results from the ITER study on atmospheric releases and the two sites are rather good for tritium, whereas the ITER reference dose values for the activation product releases are often lower, than the maximum doses for Greifswald and Cadarache. However, the percentile values fit better to the deterministic approach of ITER. Within all scenarios, the consequences of aquatic releases are in nearly all cases smaller than those from comparable releases to the atmosphere (HTO and steel). This rule is only broken once in case of accidental releases of activated steel from Cadarache. However, the uncertainties associated with the aquatic assessments are rather high and a better data base is needed to obtain more realistic and thus more reliable dose values. (orig.) [de

Experience of management of plutonium-contaminated solid and liquid wastes at the Cadarache Nuclear Research Centre

International Nuclear Information System (INIS)

Marcaillou, J.; Faure, J.C.; Tourret, G.

1981-01-01

At Cadarache the principal sources of alpha-contaminated waste are the facilities of the plutonium fuel assembly fabrication complex. The chosen management scheme shows two points where it is possible to implement procedures to limit the activities released and to reduce the storage volumes of treated waste: (1) At the fabrication units, three categories of solid waste ('rich', 'poor' and 'special') are distinguished by sorting at the time of production and by γ,n counting of the drums. The rich and special wastes with a high plutonium content are stored while awaiting treatment for recycling of the plutonium. In the case of liquid waste, different circuits are used to separate contaminated effluents and thus to limit their production; (2) In the solid-waste treatment shops, the waste has so far been compacted and then coated with bituminous cement mortar. At the same time, a new incinerator facility has been installed. The preliminary studies dealt mainly with: waste preparation (crushing) to obtain a continuous and regular feed for the incinerator; combustion (pyrolysis followed by burning of the gases and unburnt matter in the presence of excess air); containment of the equipment. Further studies will be made to determine what is to be done with the ash (treatment for plutonium recovery and/or coating). At the Effluent Treatment Station some adjustments have had to be made in order to cope with the increase in volume activity due mainly to the presence of americium. At the same time, with a view to limiting the production of treatment residues with a high alpha-emitter content it has been decided to carry out a research and development programme on the separation of americium and the improvement of the recycling of the plutonium contained in the process effluents.

The CEA intends to build a material test reactor at Cadarache (South of France). This reactor would be the central piece of a wider complex which would include experimental fuel fabrication, destructive and non destructive examinations, in-reactor on line measurement advanced methods and modelling. For 50 years this platform would provide the necessary knowledge to the nuclear industry, the safety authority and to the national decision makers. This material test reactor called Jules Horowitz reactor (JHR) could be a key facility for industry and the central component of the European research area on nuclear fission from 2010. In this paper an overview of the research complex is given and a first approach of the development effort undertaken to meet the requirements in term of : ''time to result, experimental cost, experiment quality and international co-operation. Finally are given several ways of technical development undertaken to meet the above requirements. (orig.)

The nuclear industry and public hearings

Major decisions about the French nuclear industry have been made, it is often said, without sufficiently informing and consulting the population. Laws in 1995 and 2002 provide for public hearings in order to inform the public and obtain its reactions to big projects of national interest. The responsibility for organizing a hearing is vested in an independent administrative authority, the National Commission of Public Debate (CNDP). Within 2 years, 5 issues related to the nuclear industry have been referred to it: 1) the ITER project at Cadarache in april 2003, 2) the George-Besse-II project to replace the present uranium enrichment plant at Tricastin in april 2004, 3) the research reactor Jules-Horowitz project at Cadarache in july 2004, 4) the EPR project at Flamanville in november 2004, and 5) the management of radioactive wastes in february 2005. The hearings already represent a fundamental innovation compared with earlier practices

Nuclear laundries produce large quantities of weakly contaminated effluents charged with insoluble and soluble products. In collaboration with CEA, TECHNICATOME has developed an ultrafiltration process for liquid waste from nuclear laundries, associated with prior in-solubilization of the radiochemical activity. This process 'seeded ultrafiltration' is based on the use of decloggable mineral filter media and combines very high separation efficiency with long membrane life. The efficiency of the tangential filtration unit which has been processing effluents from the Cadarache Nuclear Research Center (CEA-France) nuclear laundry since mid-1988, has been confirmed on several sites

Representatives of the French Nuclear Safety Authority (ASN, Autorite de Surete Nucleaire) and of the French National Agency for the Management of Radioactive Wastes (ANDRA, Agence nationale pour la gestion des dechets radioactifs) answer questions about an incident which occurred in a workshop, where MOx fuel was produced and which is now being dismantled. It appeared that the amount of plutonium present in the gloveboxes has been largely under-assessed: 8 kg were expected, 22 kg of plutonium have already been recovered, and finally 39 kg might be recovered by the end the dismantling operations. Other issues are addressed like the ANDRA's projects of radioactive material geological storage, their technical and institutional aspects, and then again about the late declaration of the Cadarache incident

The giant superconducting magnet system of 10,000 tons mass for fusion experiment at Cadarache, France

Sahu, A.K.

2013-01-01

The International Thermonuclear Experimental Reactor (ITER) being built at Cadarache, France has many unique features and is one of the biggest scientific adventures in the history of science and technology. Seven partners (India, EU, US, China, Japan, Korea and Russia) have made an International Organization situated at Cadarache, France to provide direction and co-ordination for R and D and construction of this project. The R and D labs and manufacturing industries are spread in these seven partner countries. Components manufactured in these countries will be transported to Cadarache in France for assembly. Institute for Plasma Research, Bhat, Gandhinagar, Gujarat is coordinating this project activities on behalf of India. The magnet system, required for confinement and control of plasma leading to fusion reaction in ITER is one of the key systems of this project. There are 18 TF (Toroidal Field) Coils, 6 PF (Poloidal Field) coils, 6 CS (Central Solenoid) coils and 18 correction coils (CC), all of which are of superconducting type. All TF and CS coils have Nb3Sn superconductor and all PF and CC coils have NbTi superconductor. Each TF coil has height 15 m and width 9 m and 330 tons mass. The biggest PF coil has diameter 24 m and 300 tons mass. The total mass of these superconducting magnet systems is about 10000 tons. Use of Nb3Sn superconductor for manufacturing superconducting cables for successful use had not reached a matured stage earlier and this project gave a thrust for significant R and D activities worldwide and now due to this project, it is a matured and reliable technology. The jacketing and manufacturing of long cables need up to about 760 m long special infrastructure at Industry. The special building built for PF coil winding at ITER, Cadarache site is of size 250 m X 45 m. All these coils are made using cable-in-conduit conductors (CICC). These long CICCs have to carry current as high as 68 kA in case of TF coils. Due to this high current and

Some recent contributions of basic nuclear science to nuclear waste transmutation

International Nuclear Information System (INIS)

Schapira, J.P.

2001-01-01

Nuclear waste transmutation aims at alleviating some long-term risks associated with actinides and with some long-lived fission products. Proposals of using accelerator driven system (ADS) to efficiently burn actinides in uranium free fuels have revitalized some basic researches in the field of nuclear and reactor physics. This is the case for high intensity accelerator in the ADS context and for the neutron source which relies to a large extent on basic nuclear physics related to spallation. There is also an experimental program called MUSE at Cadarache to study the sub-critical reactor physics with regard to its neutronics. A second area where basic research is involved is the measurement of new or more reliable neutron cross sections specific to transmutation and also to the thorium fuel cycle considered as a long-term option for ''clean'' energy production with reduced actinide production. This second area will possibly be covered by a new facility called n-TOF developed at CERN. (author)

French research in the field of nuclear agronomy

International Nuclear Information System (INIS)

Guerin De Montgareuil, P.

1964-01-01

This report presents a survey of the most important work in the field of nuclear agronomy carried out in France since the second international conference, ranging from pure research to the most direct application. As the programmes develop, so to an ever decreasing degree does this differentiation cover the distinction made in the report between the biological radiations effects and the other uses of nuclear techniques. Thus research on agricultural radio-genetics is carried on in two directions: from the theoretical and methodological angle, with comparative studies of the action of various types of radiation, the influence of dose rate and temperature, the action of chemical mutation agents, the production of chimera by gamma irradiation; and on the practical side, leading to the creation of new, hardier or earlier varieties (rice, millet, ground-nuts). Problems of pest destruction (eradication) and the preservation of foodstuffs by irradiation are also tackled by widely varied means and for totally different purposes. One operation consisting of a simple irradiation (moist seeds, potatoes...) will sometimes be associated with original studies of a biochemical or microbiological nature (for example: decomposition of starch, glucide metabolism of irradiated tubers, radiation resistance of yeasts). The nuclear technique side is represented mainly by radioisotopes (carbon 14, phosphorus 32, sulphur 35, calcium 45, potassium 42, copper 64, gold 198) and stable isotopes analysed by mass spectrometer (nitrogen 15, oxygen 18) or by neutron activation (boron 10). The studies mentioned refer to problems on different levels concerning plant physiology, agrology, agricultural entomology and zootechny. Results obtained from measurements of the humidity (neutron thermalization) and density (gamma diffusion) of a soil are also given. Numerous organisations take part in these various research programmes, each according to its speciality: cooperative private enterprise

In 1977, the IAEA organized a Coordinated Research Programme to address the needs for highly accurate actinide-nuclide decay data identified at the first Advisory Group Meeting on Transactinium Isotope Nuclear Data, held in Karlsruhe in 1975. During the years of its existence, this CRP has made significant strides towards achieving the goals outlined at Karlsruhe and subsequently refined at a second Advisory Group Meeting, held in Cadarache in 1979. In this paper, the make-up of the CRP and its work in the areas of decay-data measurement and evaluation are presented and its significant accomplishments summarized. We also discuss the contents and philosophy of the final report, containing the results of the measurements and evaluations carried out by the CRP participants, to be published following the planned termination of this Programme in November, 1984. 82 references

Changes in the practice of environment monitoring at the Cadarache Nuclear Research Centre as a function of experience. Some examples

International Nuclear Information System (INIS)

Grandin, M.

1980-09-01

From a few examples we have seen signs of a changed attitude towards the environment monitoring of nuclear plants affecting the choice of materials and the way in which they are used. Conversely the development of technology has played its own part during the same period, though it must be said in all honesty that for reasons of cost this development is not quite finished. The changes, whether voluntary or due to the pressure of local conditions, have converged in a general tendency to substitute a degree of 'interventionism' for a relatively passive observation which involves ensuring the respect of Public Health laws and checking that the local characteristics of the biosphere are not affected abnormally by the presence of the Nuclear Establishment. This radicalization 'tends generally to replace the measurement principle by that of detection, at least at the outset. On the technical side it is sometimes necessary to take strict physical measures, as for example in the case of campaigns to establish the radiological state of the locality or of supplementary investigations following an incident. It must be emphasized moreover that the special function of a Research Centre and a certain local caution in radioprotection matters have given the situation a meaning not necessarily transposable to the monitoring of a nuclear power station for example [fr

Training activities on reactors are organized by Cea on 2 specially dedicated reactors Ulysse (Saclay) and Siloette (Grenoble) and 2 research reactors Minerve (Cadarache) and Azur (Cadarache, facility managed by Technicatome). About 4000 students have been trained on Ulysse since its commissioning more than 40 years ago. The concept that led to the design of Ulysse was to build a true reactor dedicated to teaching and training activities and that was able to operate with great flexibility and under high conditions of safety, this reactor is inspired from the Argonaut-type reactor. The main specificities of Ulysse are: a nominal power of 100 kW, a maximal thermal neutron flux of 1.4 10 12 n.cm -2 .s -1 , a 90 % enriched fuel, a graphite reflector, the use of water as coolant and moderator, and 6 cadmium plates as control rods. Ulysse allows students to get practical experience on a large range of topics: approach to criticality, effect of the starting neutron source, calibration of control rods, distribution of the neutron flux in the thermal column, temperature coefficient, radiation detectors, neutron activation analysis, and radioprotection.

Internal accounting system for feed materials in the plutonium fuel fabrication complex at Cadarache

International Nuclear Information System (INIS)

Arnal, T.; Guillet, H.

1976-01-01

The internal accounting system of the Fabrication and Radiometallurgical Inspection Service (SFER) is basically designed to meet national and international requirements for nuclear materials accountancy as applied to feed materials. The authors discuss the principles underlying this accounting system for the case of the Plutonium Fuel Assembly Fabrication Complex at Cadarache. The sphere of application of the system covers more than 200 work stations and approximately 100 different materials. Some 20000 movements of feed materials per year represent transfers of a cumulative mass much greater than one ton of fissile material. A data processing system has therefore become essential in order to ensure the rapid and reliable acquisition of accounting data relating to these movements. The authors describe the system (definition of stations and material codes, description of supporting facilities used) and discuss the mode of acquisition with particular reference to relative speed of action. In conclusion, the authors indicate that the system offers interesting possibilities, in addition to its original purpose, in the following areas: Preparation of material balances; compliance with safety regulations to avert the risk of criticality; discouragement of possible diversion.

The TJ-II remote participation system was designed to follow the TJ-II discharge production, even allowing the physicist in charge of operation to be in a remote location. The system has been based on both web servers and Java technology. These elements were chosen due to its open character, security properties, platform independency and technological maturity. Web pages and Java applications permit users to access experimental systems, data servers and the operation logbook. Security resources are provided by the PAPI system, a distributed authentication and authorization system. The TJ-II remote participation tools have allowed us to command and follow the stellarator operation from Cadarache. Over 1,000 digitizer channels and more than 20 diagnostic control systems were remotely available from web pages for monitoring/programming purposes. One Java application provided on-line information about the acquisition status of channels and acquisition cards. A second Java application showed temporal evolution signals that were refreshed in an automated way on the screen after each shot. A third Java application provided access to the operation logbook. In addition to these tools, we used the VRVS videoconferencing system (FUSION community, X-Point room) and the EFDA Messenger Service for instant messaging (Jabber client). (author)

The French nuclear program is strongly based on the R and D work performed in the CEA nuclear research centers and particularly on the various experimental programs carried out in its research reactors in the frame of cooperative actions between the Commissariat a l'Energie Atomique (CEA), Framatome and Electricite de France (EDF). Several types of research reactors have been built by Technicatome and CEA to carry out successfully this considerable R and D work on fuels and materials, among them the socalled Materials Testing Reactors (MTR) SILOE (35 MW) and OSIRIS (70 MW) which are indeed very well suited for technological irradiations. Their simple and flexible design and the large irradiation space available around the core, the SILOE and OSIRIS reactors can be shared by several types of applications such as fuel and material testings for nuclear power plants, radioisotopes production, silicon doping and fundamental research. It is worthwhile recalling that Technicatome and CEA have also built research reactors fully dedicated to safety experimental studies, such as the CABRI, SCARABEE and PHEBUS reactors at Cadarache, and others dedicated to fundamental research such as ORPHEE (14 MW) and the Reacteur a Haut Flux -High Flux Reactor- (RHF 57 MW). This paper will present some of the most significant conceptual and design features of all these reactors as well as the main improvements brought to most of them in the last years. Based on this wide experience, CEA and Technicatome have specially designed for export a new multipurpose research reactor named SIRIUS, with two versions depending on the utilization spectrum and the power range (5 MW to 30 MW). At last, CEA has recently launched the preliminary project study of a new MTR, the Jules Horowitz Reactor, to meet the future needs of fuels and materials irradiations in the next 4 or 5 decades, in support of the French long term nuclear power program.

In France, two options can be considered to handle the Very Low Level Waste (VLLW) and the Low Level Waste (LLW). The first one is the incineration at CENTRACO facility and the second one is the disposal at ANDRA sites. The waste acceptance in these two channels is dependent upon the adequacy between the waste characteristics (physical chemistry and radiological) and the channel specifications. If the waste characteristics and the channel specifications (presence of significant quantities of halogens, complexing agents, organic components... or/and high activity limits) are incompatible, an alternative solution have to be identify. It consists of a waste pre-treatment process. For Cadarache LOR (Liquides Organiques Radioactifs) waste streams, two radioactive scintillation cocktails have to be treated. They are composed of a mix of organic liquids and water: for the first one, 19 % of organic compounds (xylene, mesitylene, diphenyloxazole, TBP...) and 86.9 % of water, and for the second one, 23 % of organic compounds (TBP...) and 77 % of water. They contain halogens (chlorine and fluorine), complexants agents (nitrate, sulphate, oxalate and formate) and have got αβγ spectra with mass activities equal to some 100 Bq/g. Therefore, tritium is also present. As a consequence, in order for storage acceptance at the ANDRA site, it is necessary to pre-treat the waste. An adequate solution seems to be a solidification process using NOCHAR polymers. Indeed, NOCHAR polymers correspond to an important variety of products applied to the treatment of radioactive aqueous and organic liquids (solvent, oil, solvent/oil mixing ...) and sludge through a mechanical and chemical solidification process. For Cadarache LOR, N910 and N960 respectively dedicated to the organic and aqueous liquids solidification are considered. With the N910, the organic waste solidification occurs in two steps. As the organic liquid travels moves through the polymer strands, the strands swell and

During the 1950's and 60's, the European countries built several research reactors, partially to support their emerging nuclear-powered electricity programs. Now, over forty years later, the use and operation of these reactors have both widened and grown more specialized. The irradiation reactors test materials and fuels for power reactors, produce radio-isotopes for medicine, neutro-graphies, doping silicon, and other materials. The neutron beam reactors are crucial to science of matter and provide vital support to the development of nano-technologies. Other reactors are used for other specialized services such as teaching, safety tests, neutron physics measurements... The modifications to the operating uses and the ageing of the nuclear facilities have led to increasing closures year after year. Since last ENC, for example, we have seen, only in France, the closure of the training reactor Ulysse in 2007, the closure of the safety test dedicated reactor Phebus in 2008 and recently the Phenix reactor, last fast breeder in operation in the European Community, has been shut down after a set of 'end of life' technological and physical tests. For other research reactors, safety re-evaluations have had to take place, to enable extension of reactor life. However, in the current context of streamlining and reorganization, new European tools have emerged to optimally meet the changing demands for research. However the operation market of these reactors seems now increasing in all fields. For the neutron beams reactors (FRMII, ORPHEE, ILL, ISIS,..) the experimental needs are increasing years after years, especially for nano sciences and bio sciences new needs. The measurement of residual stress on manufactured materials is also more and more utilised. All these reactors have increasing utilizations, and their future seems promising.

The complete renewal of the energy control equipment of the Van de Graaff generator at Cadarache has been accompanied by a certain number of modifications intended to improve the running and operation of the assembly. The most important work has been the addition of an extra control loop making it possible to keep the voltage on the accelerating tube in the absence of a beam. Analog simulation has made it possible to show the advantages of this solution and the effect of some of its limits. (authors) [fr

State of the art on nuclear heating measurement methods and expected improvements in zero power research reactors

2017-01-01

The paper focuses on the recent methodological advances suitable for nuclear heating measurements in zero power research reactors. This bibliographical work is part of an experimental approach currently in progress at CEA Cadarache, aiming at optimizing photon heating measurements in low-power research reactors. It provides an overview of the application fields of the most widely used detectors, namely thermoluminescent dosimeters (TLDs) and optically stimulated luminescent dosimeters. Starting from the methodology currently implemented at CEA, the expected improvements relate to the experimental determination of the neutron component, which is a key point conditioning the accuracy of photon heating measurements in mixed n-γ field. A recently developed methodology based on the use of "7Li and "6Li-enriched TLDs, pre-calibrated both in photon and neutron fields, is a promising approach to de-convolute the 2 components of nuclear heating. We also investigate the different methods of optical fiber dosimetry, with a view to assess the feasibility of online photon heating measurements, whose primary benefit is to overcome constraints related to the withdrawal of dosimeters from the reactor immediately after irradiation. Moreover, a fiber-using setup could allow measuring the instantaneous dose rate during irradiation, as well as the delayed photon dose after reactor shutdown. Some insights from potential further developments are given. Obviously, any improvement of the technique has to lead to a measurement uncertainty at least equal to that of the currently used methodology (∼5% at 1 σ). (authors)

2 subjects are treated: the regular public opinion poll ordered by CEA, EdF, COGEMA and FRAMATOME and the denuclearization of one of the nuclear research center belonging to CEA. Every year in december the BVA polling institute leads a public opinion poll about how nuclear activities are perceived by people. This year about 1000 people have been questioned about the French nuclear power program, radioactivity, safety in nuclear facilities, nuclear wastes, information and public debates. The most meaningful result is that now fewer people think that nuclear energy will play a major role in 10 or 20 years. More people now think that radioactivity even at very low doses is dangerous. In 1946 the ZOE reactor was built on the site of the ancient stronghold of Chatillon which became the nuclear research center of Fontenay-aux-roses in april 1957. From 1958 to 1962 ZOE and a pilot unit of spent fuel reprocessing were dismantled. The test reactor Triton whose definitive shutdown took place in 1982, underwent a complete decontamination, as for Minerve reactor it was removed to Cadarache. The hot laboratories in which methods concerning the fabrication of plutonium fuels, the reprocessing and the handling of high activity wastes have been settled and tested, are due to be dismantled. 20 hot cells, 134 glove boxes and about 100 tanks of liquid effluents are involved. CEA has budgeted 910 millions of francs for the complete denuclearization of this site, it will be over in 2010. (A.C.)

Atomic scale modelling of materials of the nuclear fuel cycle

Bertolus, M.

2011-10-01

This document written to obtain the French accreditation to supervise research presents the research I conducted at CEA Cadarache since 1999 on the atomic scale modelling of non-metallic materials involved in the nuclear fuel cycle: host materials for radionuclides from nuclear waste (apatites), fuel (in particular uranium dioxide) and ceramic cladding materials (silicon carbide). These are complex materials at the frontier of modelling capabilities since they contain heavy elements (rare earths or actinides), exhibit complex structures or chemical compositions and/or are subjected to irradiation effects: creation of point defects and fission products, amorphization. The objective of my studies is to bring further insight into the physics and chemistry of the elementary processes involved using atomic scale modelling and its coupling with higher scale models and experimental studies. This work is organised in two parts: on the one hand the development, adaptation and implementation of atomic scale modelling methods and validation of the approximations used; on the other hand the application of these methods to the investigation of nuclear materials under irradiation. This document contains a synthesis of the studies performed, orientations for future research, a detailed resume and a list of publications and communications. (author)

This paper is a presentation of the STAR facility, a high activity laboratory located in Cadarache Nuclear Research Center (France). The purpose of the STAR facility and of the associated processes, is the treatment, cleaning and conditioning of spent fuels from Gas Cooled Reactors (GCR) and in particular of about 2300 spent GCR fuel cartridges irradiated more than 20 years ago in Electricite de France (EDF) or CEA Uranium Graphite GCR. The processes are: to separate the nuclear fuel from the clad remains, to chemically stabilize the nuclear material and to condition it in sealed canisters. An additional objective of STAR consists in non-destructive or destructive examinations and tests on PWR rods or FBR pins in the frame of fuel development programs. The paper describes the STAR facility conceptual design (safety design rules, hot cells..) and the different options corresponding to the GCR reconditioning process and to further research and development works on various fuel types.

Design earthquakes for ITER in Europe at Cadarache

Girard, Jean-Philippe; Gruenthal, Gottfried; Nicolas, Marc

2005-01-01

The European site proposed for ITER is situated in the south of France, 40 km north-east of Aix-en-Provence, in a low to moderate seismic area according to the Global Seismic Hazard Map (GSHAP Group 1999). The tokamak building would be implemented on good bedrock made of limestone with a shear wave velocity of over 1300 m/s. Input requirements and assumptions for ITER consider that an infrequent, severe earthquake (called SL-2), although unlikely to occur during the lifetime of the facility, is assessed to demonstrate adequate protection of the public. This earthquake is assumed to have a return period of 10,000 years. An investment protection level or inspection level (where all structures, systems and components are safe) with a peak ground acceleration (pga) at 0.5 m/s 2 is also considered. As a basis, orders of magnitude of consequences, if no countermeasures were taken, are given. Four aspects are discussed: regulation, implementation of this regulation for the proposed site (site geology, tectonic and seismotectonic), a probabilistic seismic hazard assessment of the site and finally, the fulfilment of the requirements and assumptions, according to IAEA guides. As a conclusion of the studies, the main characteristics of the Cadarache European site are discussed. Preliminary studies have shown that the European site proposal will ensure a low level of project risk with respect to the seismic hazard

NOCHAR Polymers: An Aqueous and Organic Liquid Solidification Process for Cadarache LOR (Liquides Organiques Radioactifs) - 13195

To handle the Very Low Level Waste (VLLW) and the Low Level Waste (LLW) in France, two options can be considered: the incineration at CENTRACO facility and the disposal facility on ANDRA sites. The waste acceptance in these radwaste routes is dependent upon the adequacy between the waste characteristics (physical chemistry and radiological) and the radwaste route specifications. If the waste characteristics are incompatible with the radwaste route specifications (presence of significant quantities of chlorine, fluorine, organic component etc or/and high activity limits), it is necessary to find an alternative solution that consists of a waste pre-treatment process. In the context of the problematic Cadarache LOR (Liquides Organiques Radioactifs) waste streams, two radioactive scintillation cocktails have to be treated. The first one is composed of organic liquids at 13.1 % (diphenyloxazol, mesitylene, TBP, xylene) and water at 86.9 %. The second one is composed of TBP at 8.6 % and water at 91.4 %. They contain chlorine, fluorine and sulphate and have got alpha/beta/gamma spectra with mass activities equal to some kBq.g -1 . Therefore, tritium is present and creates the second problematic waste stream. As a consequence, in order for disposal acceptance at the ANDRA site, it is necessary to pre-treat the waste. The NOCHAR polymers as an aqueous and organic liquid solidification process seem to be an adequate solution. Indeed, these polymers constitute an important variety of products applied to the treatment of radioactive aqueous and organic liquids (solvent, oil, solvent/oil mixing etc) and sludge through a mechanical and chemical solidification process. For Cadarache LOR, N910 and N960 respectively dedicated to the organic and aqueous liquids solidification are considered. With the N910, the organic waste solidification occurs in two steps. As the organic liquid travels moves through the polymer strands, the strands swell and immobilise the liquid. Then as the

In his speech, Professor Noramly stressed on any research conducted in Malaysian Nuclear Agency must be comply with the national and international regulations. This to avoid any problems in the future. Moreover, research conducted in Malaysian Nuclear Agency are based on nuclear matters that seems sensitive to the public communities. In order to attract the publics on the benefit of nuclear technologies in many applications, researcher also must aware about the regulations and must take care on their safety during their experiment and working. This to make the public feels that nuclear are not the bad things and erased the worseness of nuclear technology into public minds. This strategies can be used for Malaysia in embarking for their first nuclear power program and the public feels that nuclear power are not threatened to them and consequently, they will accept that program without any issues.

The rising concerns about global warming and energy security have spurred a revival of interest in nuclear energy, giving birth to a 'nuclear power renaissance' in several countries in the world. Particularly in Brazil, in the recent years, the nuclear power renaissance can be seen in the actions that comprise its nuclear program, summarily the increase of the investments in nuclear research institutes and the government target to design and build the Brazilian Multipurpose research Reactor (BMR). In the last 50 years, Brazilian research reactors have been used for training, for producing radioisotopes to meet demands in industry and nuclear medicine, for miscellaneous irradiation services and for academic research. Moreover, the research reactors are used as laboratories to develop technologies in power reactors, which are evaluated today at around 450 worldwide. In this application, those reactors become more viable in relation to power reactors by the lowest cost, by the operation at low temperatures and, furthermore, by lower demand for nuclear fuel. In Brazil, four research reactors were installed: the IEA-R1 and the MB-01 reactors, both at the Instituto de Pesquisas Energeticas Nucleares (IPEN, Sao Paulo); the Argonauta, at the Instituto de Engenharia Nuclear (IEN, Rio de Janeiro) and the IPR-R1 TRIGA reactor, at the Centro de Desenvolvimento da Tecnologia Nuclear (CDTN, Belo Horizonte). The present paper intends to enumerate the characteristics of these reactors, their utilization and current academic research. Therefore, through this paper, we intend to collaborate on the BMR project. (author)

After the events at the Japanese nuclear power plant of Fukushima Daiichi, the German federal government decided that Germany will give up electricity generation from nuclear power within a decade. The last reactor will be disconnected from the power grid in 2022. Helping to make this opt-out as safe as possible is one of the duties of the Helmholtz Association with its Nuclear Safety Research Program within the Energy Research Area. Also the demolition of nuclear power plants and the repository problem will keep society, and thus also research, busy for a number of decades to come. Giving up electricity production from nuclear power thus must not mean giving up the required nuclear technology competences. In the fields of reactor safety, demolition, final storage, radiation protection, and crisis management, in critical support of international developments, and for competent evaluation of nuclear facilities around Germany, these competences will be in demand far beyond the German opt-out. This is the reason why the final report by the Ethics Committee on 'Safe Energy Supply' emphasizes the importance of nuclear technology research. Close cooperation on national, European and international levels is indispensable in this effort. Also nuclear safety research in the Helmholtz Association is aligned with the challenges posed by the opt-out of the use of nuclear power. It is important that the high competences in the areas of plant safety and demolition, handling of radioactive waste, and safe final storage as well as radiation protection be preserved. The Nuclear Safety Research Program within the Energy Research Area of the Helmholtz Association therefore will continue studying scientific and technical aspects of the safety of nuclear reactors and the safety of nuclear waste management. These research activities are provident research conducted for society and must be preserved for a long period of time. The work is closely harmonized with the activities of the

Forty years ago, the North Rhine-Westphalian State Government founded the then Juelich Nuclear Research Center. After a growth period of the reactor engineering program until 1980, claiming a share of 42% of R and D resources, that share declined continuously to a present level of 8%. This development is an expression of the activities successfully completed in the past, of progress achieved in industrial reactor development, but also of the fact that the high temperature reactor, which had been run successfully for twenty years, failed as a technical scale THTR-300 version. The Center has reorientated its line of research in a process of structural reshuffle beginning some fifteen years ago and still going on. Information technology, materials research, life sciences, environmental research, and energy technology have become main activities of equal weight. Activities specific to nuclear reactors have been incorporated in this new line of work as nuclear safety research and work on safe repository storage. (orig.) [de

The PLINIUS experimental platform at CEA Cadarache is dedicated to the experimental study of nuclear reactor severe accidents thanks to experiments between 2000 and 3500 K with prototypic corium. Corium is the mixture that would be formed by an hypothetical core melting and its mixing with structural materials. Prototypical corium has the same chemical composition as the corium corresponding to a given accident scenario but has a different isotopic composition (use of depleted uranium,...). Research programs and test series have been performed to study corium thermophysical properties, fission product behaviour, corium spreading, solidification and interaction with concrete as well as its coolability. It was the frame of research training of many students and was realized within national, European and international collaborations. (author)

The working group was to assess the need and orientation of nuclear energy research (apart from research on nuclear waste management and fusion technology) up until the year 2000 in Finland and to propose framework schemes and organization guidelines for any forthcoming publicly financed research programmes from 1995 onwards. The main purpose of nuclear energy research is to ensure the safety and continued development of Finland's existing nuclear power plants. Factors necessarily influencing the orientation of research are Parliaments decision of late 1993 against further nuclear capacity in the country, the need to assess reactor safety in the eastern neighbour regions, and Finland's potential membership in the European Union. The working group proposes two new research programmes similar to the current ones but with slightly modified emphasis. Dedicated to reactor safety and structural safety respectively, they would both cover the four years from 1995 to 1998. A separate research project is proposed for automation technology. In addition, environmental research projects should have a joint coordination unit. (9 figs., 4 tabs.)

A future for nuclear sites beyond their service life. Nuclear site value development

International Nuclear Information System (INIS)

2008-01-01

As the nuclear industry moves into a new development phase, many facilities built in the fifties and sixties are reaching the end of their service life. Dismantling them and rehabilitating the sites on which they stand is a major industrial challenge which will give rise to a number of new projects. AREVA has more than 20 years' experience in these highly technical fields. As more and more sites reach the end of their service life, AREVA considers nuclear site value development as a fully-fledged industrial activity. The group's competencies in this field have been grouped together to form a dedicated entity: the Nuclear Site Value Development Business Unit, created in 2008. Several billion euros are invested in site value development projects which are far-reaching and complex, and often last for several decades. Long before work actually begins, lengthy studies and preparations are required to schedule operations, select the techniques to be used and optimize costs and deadlines. The Nuclear Site Value Development BU is currently working on four major projects involving its own facilities and those of the CEA: - La Hague: dismantling of the first generation of used fuel recycling facilities. Between 1966 and 1998, almost 5,000 tons of used fuel from graphite-moderated gas-cooled reactors, 4,500 tons of light water reactor fuel, as well as fuel from fast reactors and research reactors, were treated at UP2 400, the very first industrial recycling plant on the La Hague site. - Marcoule: first-time dismantling of a recycling plant. 1,000 rooms to be cleaned up, 30,000 tons of waste to be treated, 30 years of work. - Cadarache: first-time dismantling of a Mox fuel fabrication plant. The Cadarache plant was commissioned in 1962 to fabricate fuel for fast reactors; this was followed by MOX fuel for light water reactors, an activity which continued until the plant was shut down in 2003. - Annecy and Veurey: giving a new lease of life to former industrial sites in built

Saint Jean, C. de; Habert, B.; Litaize, O.; Noguere, G.; Suteau, C.

2008-01-01

The development of a software tool (CONRAD) was initiated at CEA/Cadarache to give answers to various problems arising in the data analysis of nuclear reactions. This tool is then characterized by the handling of uncertainties from experimental values to covariance matrices for multi-group cross sections. An object oriented design was chosen allowing an easy interface with graphical tool for input/output data and being a natural framework for innovative nuclear models (Fission). The major achieved developments are a data model for describing channels, nuclear reactions, nuclear models and processes with interface to classical data formats, theoretical calculations for the resolved resonance range (Reich-Moore) and unresolved resonance range (Hauser-Feshbach, Gilbert-Cameron,...) with nuclear model parameters adjustment on experimental data sets and a Monte Carlo method based on conditional probabilities developed to calculate properly covariance matrices. The on-going developments deal with the experimental data description (covariance matrices) and the graphical user interface. (authors)

Kim, S. S.; Song, G. D.

2000-01-01

The main objective of this study is to analyze the effects of nuclear R and D fund to nuclear generation cost and to assess the adaptability of fund size through the comparison with the nuclear research fund in Japan. It was estimated that nuclear R and D fund increased the average annual unit cost of nuclear power generation by 1.14 won/kWh. When the size of nuclear R and D fund is compared with that in Japan, this study suggests that the current nuclear R and D fund should be largely increased taking into consideration the ratio of R and D fund to nuclear generation

The advancement of space exploration using nuclear science and technology has been a goal sought by many individuals over the years. The quest to enable space nuclear applications has experienced many challenges such as funding restrictions; lack of political, corporate, or public support; and limitations in educational opportunities. The Center for Space Nuclear Research (CSNR) was established at the Idaho National Laboratory (INL) with the mission to address the numerous challenges and opportunities relevant to the promotion of space nuclear research and education.1 The CSNR is operated by the Universities Space Research Association and its activities are overseen by a Science Council comprised of various representatives from academic and professional entities with space nuclear experience. Program participants in the CSNR include academic researchers and students, government representatives, and representatives from industrial and corporate entities. Space nuclear educational opportunities have traditionally been limited to various sponsored research projects through government agencies or industrial partners, and dedicated research centers. Centralized research opportunities are vital to the growth and development of space nuclear advancement. Coordinated and focused research plays a key role in developing the future leaders in the space nuclear field. The CSNR strives to synchronize research efforts and provide means to train and educate students with skills to help them excel as leaders.

Detailed information about the performance of nuclear reactor systems, and especially about the nuclear fuel, is vital in determining the consequences of a reactor accident. Fission products released from the fuel during accidents are the ultimate safety concern to the general public living in the vicinity of a nuclear reactor plant. Safety research conducted at the Idaho National Engineering Laboratory (INEL) in support of the U.S. Nuclear Regulatory Commission (NRC) has provided the NRC with detailed data relating to most of the postulated nuclear reactor accidents. Engineers and scientists at the INEL are now in the process of gathering data related to the most severe nuclear reactor accident - the core melt accident. This paper describes the focus of the nuclear reactor safety research at the INEL. The key results expected from the severe core damage safety research program are discussed

Janzekovic, H.; Krizman, M.

2006-01-01

Many countries, particularly in Europe, started with nuclear programs in the fifties of the last century. As a consequence nuclear research institutes were established, among them also the Institute Jozef Stefan (IJS) in Slovenia. The nuclear activities at the IJS were related to the development of uranium ore processing technology and technologies comprising uranium oxide and hexafluoride. After very intensive period of nuclear activities the decline began step by step due to different reasons. Various approaches of the termination and decommissioning of facilities were used. The inspectors of the Slovenian Nuclear Safety Administration (SNSA), the responsible authority, started intensive activities at the IJS at the end of 2004. All together 22 research laboratories or research units were included in the inspection program and around 50 researchers of the IJS were involved into the inspection procedures. The inspection was very intensive in the laboratories and storages where past nuclear activities took place and were later on abandoned. As a result several contaminated equipments and sites in addition to around 200 unregistered sources were found. The majority of these sources is related to past nuclear activities. The inspection program related to the terminated research activities is still in progress. The IJS immediately started with the remediation activities including the development of methodology related to decontamination of radioactive liquids. The decontamination of two nuclear laboratories and three different storages of radioactive waste at its sites is in progress. Sixty of the above mentioned sources have been already stored in the Central Interim Storage for Radioactive Waste. (author)

The U.S. Nuclear Regulatory Commission, Office of Nuclear Regulatory Research, has established the Nuclear Plant Aging Research (NPAR) program in its Division of Engineering Technology. Principal contractors for this program include Oak Ridge National Laboratory, Brookhaven National Laboratory, Idaho National Engineering Laboratory, and Pacific Northwest Laboratory. The program goals are: to identify and characterize time-dependent degradation (aging) of nuclear plant safety-related electrical and mechanical components which could lead to loss of safety function; to identify and recommend methods for detecting and trending aging effects prior to loss of safety function so that timely maintenance can be implemented; and to recommend maintenance practices for mitigating the effects of aging. Research activities include prioritization of system and component aging in nuclear plants, characterization of aging degradation of specific components including identification of functional indicators useful for trending degradation, and testing of practical methods and devices for measuring the functional indicators. Aging assessments have been completed on electric motors, snubbers, motor-operated valves, and check valves. Testing of trending methods and devices for motor-operated valves and check valves is in progress

1964-07-01

This report presents a survey of the most important work in the field of nuclear agronomy carried out in France since the second international conference, ranging from pure research to the most direct application. As the programmes develop, so to an ever decreasing degree does this differentiation cover the distinction made in the report between the biological radiations effects and the other uses of nuclear techniques. Thus research on agricultural radio-genetics is carried on in two directions: from the theoretical and methodological angle, with comparative studies of the action of various types of radiation, the influence of dose rate and temperature, the action of chemical mutation agents, the production of chimera by gamma irradiation; and on the practical side, leading to the creation of new, hardier or earlier varieties (rice, millet, ground-nuts). Problems of pest destruction (eradication) and the preservation of foodstuffs by irradiation are also tackled by widely varied means and for totally different purposes. One operation consisting of a simple irradiation (moist seeds, potatoes...) will sometimes be associated with original studies of a biochemical or microbiological nature (for example: decomposition of starch, glucide metabolism of irradiated tubers, radiation resistance of yeasts). The nuclear technique side is represented mainly by radioisotopes (carbon 14, phosphorus 32, sulphur 35, calcium 45, potassium 42, copper 64, gold 198) and stable isotopes analysed by mass spectrometer (nitrogen 15, oxygen 18) or by neutron activation (boron 10). The studies mentioned refer to problems on different levels concerning plant physiology, agrology, agricultural entomology and zootechny. Results obtained from measurements of the humidity (neutron thermalization) and density (gamma diffusion) of a soil are also given. Numerous organisations take part in these various research programmes, each according to its speciality: cooperative private enterprise

Vanhavere, F.; Eggermont, G.

2001-01-01

In these days of public aversion to nuclear power, it can be important to point at the medical applications of ionising radiation. Not only the general public, but also the authorities and research centres have to be aware of these medical applications, which are not without risk for public health. Now that funding for nuclear research is declining, an opening to the medical world can give new opportunities to a nuclear research centre. A lot of research could be done where the tools developed for the nuclear power world are very useful. Even new applications for the research reactors like BNCT (boron neutron capture therapy) can be envisaged for the near future. In this contribution an overview will be given of the different techniques used in the medical world with ionising radiation. The specific example of the Belgian Nuclear Research Centre will be given where the mission statement was changed to include a certain number of medical research topics. (authors)

For the first phase (1992-1995) of the current research program under nuclear reactor safety enhancement project, the primary objective was placed on the development of an improved cavity design and on the improvement of theoretical models of the separate effects for major severe accident phenomena occurring in the reactor cavity. Also, during the fourth year of this project, small-scale experiments were performed to visualize the fundamental phenomena of boiling in narrow spaces that may exist between the debris crust and the reactor vessel lower head in preparation for the large-scale in-vessel cooling experiment planned for the second phase of the project (1996-2001). Separate effect tests have been performed during the first phase spanning the high pressure melt ejection (HPME) resulting in the direct containment heating (DCH), crust formation during cooling of the high temperature melt, fuel coolant interaction (FCI) in the process of injecting coolant onto the reactor cavity, and the molten core concrete interaction (MCCI). Some research programs were subcontracted with universities. Steam condensation on the containment inner wall was investigated by the POSTECH, while the experimental technique for the simultaneous measurement of particle size and velocity was developed by the KAIST. The second phase experimental projects center about the in-vessel accident management tests SONATA-IV (Simulation of Naturally Arrested Thermal Attack in Vessel) and ex-vessel accident management tests TOCATA-XV (Tests on Cavity Arrested Thermal Attack ex Vessel). In preparation for the second phase in-vessel experimental program, one of our research staff has participated in the PHEBUS-FP program in CEA Cadarache, France. Small-scale scoping tests were performed for the study of in-vessel cooling of debris in the lower head. (Abstract Truncated)

2005-01-01

The present book contains the proceedings of the third workshop in a series of workshops previously held in Seyssins in 1994 and 1998. The meeting was jointly organized by different divisions of CEA and two major international laboratories. In the opening address, Prof. B. Bigot, the French High Commissioner for Atomic Energy, outlined France's energy policy for the next few decades. He emphasized the continuing progress of nuclear fission in both technical and economic terms, allowing it to contribute to the energy needs of the planet even more in the future than it does today. Such progress implies a very strong link between fundamental and applied research based on experimental and theoretical approaches. The workshop gathered the different nuclear communities studying the fission process, including topics as the following: - nuclear fission experiments, - spectroscopy of neutron rich nuclei, - fission data evaluation, - theoretical aspects of nuclear fission, - and innovative nuclear systems and new facilities. The scientific program was suggested by an International Advisory Committee. About 100 scientists from 13 different countries attended the conference in the friendly working atmosphere of the Castle of Cadarache in the heart of the Provence. The proceedings of the workshop were divided into 11 sections addressing the following subject matters: 1. Cross sections and resonances (5 papers); 2. Fission at higher energies - I (5 papers); 3. Fission: mass and charge yields (4 papers); 4. Light particles and cluster emission (4 papers); 5. Spectroscopy of neutron rich nuclei (5 papers); 6. Resonances, barriers, and fission times (5 papers); 7. Fragment excitation and neutron emission (4 papers); 8. Mass and energy distributions (4 papers); 9. Needs for nuclear data and new facilities - I (4 papers); 10. Angular momenta and fission at higher Energies - II (3 papers); 11. New facilities - II (2 papers). A poster session of 8 presentations completed the workshop

Nuclear Research and Society: Introduction

International Nuclear Information System (INIS)

Meskens, G.

2007-01-01

Throughout the last decades, the ever growing use of technology in our society has brought along the need to reflect on the related impact on the ecosystem and on society as such. There is growing evidence that the complexity of issues of risk governance and ethics coming with applications of nuclear technology, fossil fuels, human cloning and genetically modified crops cannot be tackled by pure rational technological and economical reasoning alone. In order to provide an answer to the concerns of civil society, this complexity needs a transdisciplinary approach, taking into account social and ethical aspects. Starting from the insight that a full understanding of the benefits and risks of applications of radioactivity and nuclear technology requires also an understanding of the context of application and a sense for the social and ethical aspects of the situation, SCK-CEN started in 1999 with its PISA research programme (Programme of Integration of Social Aspects into nuclear research). The aim of the research was (and still is) to give the nuclear researchers more insight into the complex social and ethical aspects of nuclear applications and to shed at the same time new lights on how to organise in a more effective way the dialogue and interaction with civil society. Originally, the programme was set up along thematic research tracks, involving nuclear scientists, engineers, philosophers and social scientists, and focussing on specific projects carried out by way of PhD- or post-doc research in cooperation with universities. The research tracks focussed on themes such as Sustainability and nuclear development, Transgenerational ethics of radioactive waste management, Legal aspects and liability, Risk governance and Expert culture. In addition to this thematic research, PISA organised reflection groups in interaction with universities, authorities and private actors. These interdisciplinary discussion sessions aimed to exchange knowledge and views on typical

High committee for nuclear safety transparency and information. November 20, 2009 meeting of the High Committee

International Nuclear Information System (INIS)

2009-11-01

The high committee for the nuclear safety transparency and information (HCTISN) is an information, consultation and debate authority devoted to the assessment of the risks linked with nuclear activities and to the analysis of their impact on public health, on the environment and on nuclear safety. Each year, the HCTISN organizes several ordinary meetings in order to analyze some specific topics of the moment, and, depending on the events, some extraordinary meetings. This document is the proceedings of an extraordinary meeting about the information and transparency in relation with the management of nuclear materials and wastes at all stages of the fuel cycle. The reason of this meeting is a request from the French Minister of ecology, energy, sustainable development and sea (MEEDDM) after the broadcast of a TV documentary entitled 'wastes: the nuclear industry nightmare' and the publication of a press article affirming that 'our nuclear wastes are hidden in Siberia'. The Minister expressed his wish to have the question of the international trade of nuclear materials examined by the HCTISN. The document is organized as follows: a first part presents the hearings of the general direction of energy and climate (DGEC), of the nuclear safety authority (ASN), of EdF, of Areva, of the CEA, of the senior official for the defense and security of the MEEDDM, of Rosatom company and of Greenpeace organisation. A second part examines the incident which took place in October 2009 at the plutonium technology workshop (ATPu) of Cadarache, where about 22 to 39 kg of plutonium powder were discovered in the gloveboxes of this facility, decommissioned in 2005 and undergoing dismantlement today. This part presents the hearings of the CEA, of AREVA, of the Institute of radiation protection and nuclear safety (IRSN), of the ASN, of the hygiene, safety and labour conditions committee (CHSCT) of Areva and CEA, and of the local information commission (CLI) of Cadarache, in relation with

Efforts at nuclear safety research have expanded year by year in Japan, in term of money and technical achievement. The Atomic Energy Commission set last year the five year nuclear safety research program, a guideline by which various research institutes will be able to develop their own efforts in a concerted manner. From the results of the nuclear safety research which cover very wide areas ranging from reactor engineering safety, safety of nuclear fuel cycle facilities, prevention of radiation hazards to the adequate treatment and disposal of radioactive wastes, AIJ hereafter focuses of LWR engineering safety and prevents two articles, one introducing the current results of the NSSR program developed by JAERI and the other reporting the LWR reliability demonstration testing projects being promoted by MITI. The outline of these demonstration tests was reported in this report. The tests consist of earthquake resistance reliability test of nuclear power plants, steam generator reliability tests, valve integrity tests, fuel assembly reliability tests, reliability tests of heat affected zones and reliability tests of pumps.

The management of long-living and high level radioactive wastes in France belongs to the framework of the December 30, 1991 law which defines three ways of research: the separation and transmutation of radionuclides, their reversible storage or disposal in deep geologic formations, and their processing and surface storage during long duration. Research works are done in partnership between public research and industrial organizations in many French and foreign laboratories. Twelve years after its enforcement, the impact of this law has overstepped the simple research framework and has led to a deep reflection of the society about the use of nuclear energy. This short paper presents the main results obtained so far in the three research ways, the general energy policy of the French government, the industrial progresses made in the framework of the 1991 law and the international context of the management of nuclear wastes.

2008-01-01

The CEA's Nuclear Energy Division (DEN) nuclear facilities currently include seventeen reactors and thirty six other miscellaneous facilities, particularly laboratories, fuel processing units and facilities specific to waste management. Some of these are currently being dismantled or must be dismantled soon so that the DEN, the Nuclear Energy Division, can construct new equipment and thus have available a range of R and D facilities in line with the issues of the nuclear industry of the future. At CEA, the first nuclear facility dismantling operations go back several dozen years and involve numerous and varied facilities. The first operations of any significance took place in the 1960's and 1970's and covered, for example, the first plutonium plant at Fontenay-aux-Roses (total dismantling) and small research reactors or critical models - CESAR and PEGGY at Cadarache and MINERVE at Fontenay-aux Roses (civil engineering cleaned up and kept). At La Hague, the dismantling of AT1, a pilot workshop used by the CEA during the 1970's to process irradiated fuels from fast neutron reactors, was completed in March 2001 (IAEA former stage 3, excluding civil engineering demolition). On the other hand, during this period of first dismantling, the intermediate-sized reactors (G1, Rapsodie) were only partially dismantled after shut down, mainly due to the lack of graphite and sodium waste management routes at the time. About twenty facilities were thus dealt with up to 2001, in other words about half of all the nuclear facilities shut down permanently before this date. (authors)

The international community has recognized the serious threat posed by nuclear and other radioactive material out of regulatory control. To address these concerns, the Office of Nuclear Security of the international Atomic Energy Agency (IAEA) is developing, inter alia, guidance for nuclear forensics to assist Member States. According to the IAEA Incident and Trafficking Database (ITDB) of the IAEA to record the illegal trade and trafficking incidents of nuclear material or other radioactive material, incidents of 2331 have been reported in 1993 to 2012. These incidents mean that we are not safe for nuclear material. In order to solve the case generated by the illicit trafficking of nuclear material and the efficient management of nuclear material, the study of nuclear forensics is very important. In this study, we investigated the analytical techniques and the current status of nuclear forensics research. In this study, we investigated the current status of research of nuclear forensics, procedures for analysis and nuclear forensics analysis technique. A result of the study, we have been found that the major institutes and laboratory actively research on analysis technique and nuclear forensics. However, research on nuclear forensics is still in early stage, ROK is necessary preliminary survey of analysis technique and foundation of physical, chemical, and morphology characteristics of nuclear materials

Reddy, A.V.R.

2007-01-01

Research in nuclear chemistry has seen a huge growth over the last few decades. The large umbrella of nuclear chemistry includes several research areas such as nuclear fission, reactions, spectroscopy, nuclear probes and nuclear analytical techniques. Currently, nuclear chemistry research has extended its horizon into various applications like nuclear medicine, isotopes for understanding physico chemical processes, and addressing environmental and biomedical problems. Tremendous efforts are going on for synthesizing new elements (isotopes), isolating physically or chemically wherever possible and investigating their properties. Theses studies are useful to understand nuclear and chemical properties at extreme ends of instability. In addition, nuclear chemists are making substantial contribution to astrophysics and other related areas. During this talk, a few of the contributions made by nuclear chemistry group of BARC will be discussed and possible future areas of research will be enumerated. (author)

Current research and development at the Nuclear Research Center Karlsruhe

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.)

The U.S. Department of Energy (DOE) created a new R and D program called Nuclear Energy Research Initiative (NERI)' in FY 1999 with the appropriation of $19 million. The major objectives of the NERI program is to preserve the nuclear science and engineering infrastructure in the U.S. and to maintain a competitive position in the global nuclear market in the 21st century. In may, 1999, the DOE selected 45 research proposals for the first year of the NERI program. The proposals are classified into the following five R and D areas: Proliferation Resistant Reactors and/or Fuel Cycles, New Reactor Designs, Advanced Nuclear Fuel, New Technology for Management of Nuclear Waste, Fundamental Nuclear Science. Since the NERI is a very epoch-making and strategic nuclear research program sponsored by the U.S. government, the trend of the NERI is considered to affect the future R and D programs in Japanese nuclear industries and research institutes including JAERI. The present report summarizes the analyzed results of the selected 45 research proposals. Staffs comments are made on each proposal in connection with the R and D activities in JAERI. (author)

In 1998, an initiative was taken by SCK-CEN to include social sciences and humanities into its research programme. As a result, two working groups were created to discuss two broad items: (1) ethical choices in radiation protection; and (2) the role and culture of nuclear experts. The general objectives of SCK-CEN's social sciences programme are: (1) to improve the nuclear research approach by integrating social sciences - where needed- to solve complex problems in interaction with society; (2) to stimulate university collaboration with social disciplines in learning process towards transdisciplinary and improved social responsibility; (3) to improve the training of nuclear experts of SCK-CEN by gaining insight in their expert culture and implicit ethical choices; (4) to develop projects and an original transdisciplinary programme and project management by involving young and senior scientists, a variety of university opinions and relevant actors from industry and society. Along these lines, projects were developed on sustainability and nuclear development, transgenerational ethics related to disposal of long-lived radioactive waste and cognitive dissonance effects, legal aspects and liability, non-radiological aspects of nuclear emergencies and safety. Progress and major achievements in SCK-CEN's social science programme in 2000 are summarised

2009-01-01

Experimental nuclear physics has been one of the top research activities at the Rudjer Boskovic Institute, the largest and leading Croatian research center in science and applications. The RBI nuclear physics group has strong link with the researchers at the University of Zagreb. RBI scientists perform experiments at the RBI Tandem accelerator facility and at the top European experimental facilities in collaboration with the prominent research groups in the field. Current status of the RBI experimental nuclear physics research and our recent activities aimed to strengthen our position at the RBI and to increase our international reputation and impact in collaborative projects will be presented. Part of these activities is focused on local accelerator facilities, at present mainly used for application research, and their increased usage for nuclear physics research and for development and testing of novel research equipment for large international facilities. Upgrade of the local research equipment is on the way through FP7 REGPOT project 'CLUNA: Clustering phenomena in nuclear physics: strengthening of the Zagreb-Catania-Birmingham partnership'. Recently, steps to exploit potential of the facility for nuclear astrophysics research have been initiated. Possible future actions for further strengthening of the RBI experimental nuclear physics research will be discussed.(author)

Validation of iron nuclear data for the neutron calculation of nuclear reactors

International Nuclear Information System (INIS)

Vaglio-Gaudard, C.

2010-01-01

The GEN-III and GEN-IV reactors will be equipped with heavy reflectors. However, the existing integral validation of the iron nuclear data in the latest JEFF3 European library in the frame of the neutron calculation of the heavy reflector is very partial: some results exist concerning fast reactors but there is no result corresponding to the LWR heavy reflector. No clear trend on the JEFF3 iron cross sections was brought into evidence up to now for fission reactor calculations. Iron nuclear data were completely re-evaluated in the JEFF3 library. Despite the fact that iron is widely used in the nuclear industry, large uncertainties are still associated with its nuclear data, particularly its inelastic cross section which is very important in the neutron slowing down. A validation of 56 Fe nuclear data was performed on the basis of the analysis of integral experiments. Two major critical experiments, the PERLE experiment and the Gas Benchmark, were interpreted with 3D reference Monte-Carlo calculations and the JEFF3.1.1 library. The PERLE experiment was recently performed in the EOLE zero-power facility (CEA Cadarache). This experiment is dedicated to heavy reflector physics in GEN-III light water reactors. It was especially conceived for the validation of iron nuclear data. The Gas Benchmark is representative of a Gas Fast Reactor with a stainless steel reflector (with no fertile blanket) in the MASURCA facility (CEA Cadarache). Radial traverses of reaction rates were measured to characterize flux attenuation at various energies in the reflector. The results of the analysis of both experiments show good agreement between the calculations and the measurements, which is confirmed by the analysis of complementary experiments (ZR-6M, MISTRAL4, CIRANO-ZONA2B). A process of re-estimating the 56 Fe nuclear data was implemented on the basis of feedback from these two experiments and the RDN code. This code relies on a non-linear regression method using an iterative

1964-07-01

This report presents a survey of the most important work in the field of nuclear agronomy carried out in France since the second international conference, ranging from pure research to the most direct application. As the programmes develop, so to an ever decreasing degree does this differentiation cover the distinction made in the report between the biological radiations effects and the other uses of nuclear techniques. Thus research on agricultural radio-genetics is carried on in two directions: from the theoretical and methodological angle, with comparative studies of the action of various types of radiation, the influence of dose rate and temperature, the action of chemical mutation agents, the production of chimera by gamma irradiation; and on the practical side, leading to the creation of new, hardier or earlier varieties (rice, millet, ground-nuts). Problems of pest destruction (eradication) and the preservation of foodstuffs by irradiation are also tackled by widely varied means and for totally different purposes. One operation consisting of a simple irradiation (moist seeds, potatoes...) will sometimes be associated with original studies of a biochemical or microbiological nature (for example: decomposition of starch, glucide metabolism of irradiated tubers, radiation resistance of yeasts). The nuclear technique side is represented mainly by radioisotopes (carbon 14, phosphorus 32, sulphur 35, calcium 45, potassium 42, copper 64, gold 198) and stable isotopes analysed by mass spectrometer (nitrogen 15, oxygen 18) or by neutron activation (boron 10). The studies mentioned refer to problems on different levels concerning plant physiology, agrology, agricultural entomology and zootechny. Results obtained from measurements of the humidity (neutron thermalization) and density (gamma diffusion) of a soil are also given. Numerous organisations take part in these various research programmes, each according to its speciality: cooperative private enterprise

Research in nuclear astrophysics

Lattimer, J.M.; Yahil, A.

The interaction between nuclear theory and some outstanding problems in astrophysics is examined. We are actively researching both the astrophysics of gravitational collapse, neutron star birth, and the emission of neutrinos from supernovae, on the one hand, and the nuclear physics of the equation of state of hot, dense matter on the other hand. There is close coupling between nuclear theory and the supernova phenomenon; in fact, nuclear matter properties, especially at supernuclear densities, might be best delineated by astrophysical considerations. Our research has also focused on the neutrinos emitted from supernovae, since they are the only available observables of the internal supernova mechanism. The recent observations of neutrinos from SN 1987A proved to be in remarkable agreement with models we pioneered in the one and one half years prior to its explosion in February 1987. We have also developed a novel hydrodynamical code in which shocks are treated via Riemann resolution rather than with artificial viscosity. We propose to modify it to use implicit differencing and to include multi-group neutrino diffusion and General Relativity. In parallel, we are extending calculations of the birth of a neutron star to include convection and mass accretion, by incorporating a hydrodynamic envelope onto a hydrostatic core. In view of the possible recent discovery of a pulsar in SN1987A, we are including the effects of rotation. We are undertaking a detailed comparison of current equations of state, focusing on disagreements regarding the nuclear incompressibly, symmetry energy and specific heat. Especially important is the symmetry energy, which below nuclear density controls free proton fractions and weak interaction rates and above this density critically influences the neutron star maximum mass and binding energy. 60 refs

2002-01-01

We investigated the degree of Japan's contribution to the nuclear medical research in the last decade. Articles published in 1991-2000 in highly reputed nuclear medical journals were accessed through the MEDLINE database. The number of articles having affiliation with a Japanese institution was counted along with publication year. In addition, shares of top-ranking countries were determined along with their trends over time. Of the total number of articles (7,788), Japan's share of articles in selected nuclear medical journals was 11.4% (889 articles) and ranked 2nd in the world after the USA (2,645 articles). The recent increase in the share was statistically significant for Japan (p=0.02, test for trend). Japan's share in nuclear medical research output is much higher than that in other biomedical fields. (author)

Nuclear Explosion Monitoring History and Research and Development

2008-12-01

Within a year after the nuclear detonations over Hiroshima and Nagasaki the Baruch Plan was presented to the newly formed United Nations Atomic Energy Commission (June 14, 1946) to establish nuclear disarmament and international control over all nuclear activities. These controls would allow only the peaceful use of atomic energy. The plan was rejected through a Security Council veto primarily because of the resistance to unlimited inspections. Since that time there have been many multilateral, and bilateral agreements, and unilateral declarations to limit or eliminate nuclear detonations. Almost all of theses agreements (i.e. treaties) call for some type of monitoring. We will review a timeline showing the history of nuclear testing and the more important treaties. We will also describe testing operations, containment, phenomenology, and observations. The Comprehensive Nuclear Test Ban Treaty (CTBT) which has been signed by 179 countries (ratified by 144) established the International Monitoring System global verification regime which employs seismic, infrasound, hydroacoustic and radionuclide monitoring techniques. The CTBT also includes on-site inspection to clarify whether a nuclear explosion has been carried out in violation of the Treaty. The US Department of Energy (DOE) through its National Nuclear Security Agency's Ground-Based Nuclear Explosion Monitoring R&D Program supports research by US National Laboratories, and universities and industry internationally to detect, locate, and identify nuclear detonations. This research program builds on the broad base of monitoring expertise developed over several decades. Annually the DOE and the US Department of Defense jointly solicit monitoring research proposals. Areas of research include: seismic regional characterization and wave propagation, seismic event detection and location, seismic identification and source characterization, hydroacoustic monitoring, radionuclide monitoring, infrasound monitoring, and

For promoting and improving nuclear safety research activities, this report gives an insight on the scope of safety research and its role in the safety management of nuclear installations, and suggests measures to adequately utilize the research results through taking an optimized role share among research organizations. Several measures such as cooperative planning of common research areas and proper role assignment, improvement of the interfaces among researchers, and reflection of end-users' opinion in the course of planning and conducting research to promote application of research results are identified. It is expected that the identified measures will contribute to enhancing the efficiency and effectiveness of nuclear safety research, if they are implemented after deliberating with the government and safety research organizations

A world class nuclear research reactor complex for South Africa's nuclear future

2008-01-01

South Africa recently made public its rather ambitious goals pertaining to nuclear energy developments in a Draft Policy and Strategy issued for public comment. Not much attention was given to an important tool for nuclear energy research and development, namely a well equipped and maintained research reactor, which on its own does not do justice to its potential, unless it is fitted with all the ancillaries and human resources as most first world countries have. In South Africa's case it is suggested to establish at least one Nuclear Energy Research and Development Centre at such a research reactor, where almost all nuclear energy related research can be carried out on par with some of the best in the world. The purpose of this work is to propose how this could be done, and motivate why it is important that it be done with great urgency, and with full involvement of young professionals, if South Africa wishes to face up to the challenges mentioned in the Draft Strategy and Policy.

2007-07-01

Nuclear Power Engineering Corporation (NUPEC) studied high moderation full MOX cores as a part of advanced LWR core concept studies from 1994 to 2003 supported by the Ministry of Economy, Trade and Industry. In order to obtain the major physics characteristics of such advanced MOX cores, NUPEC carried out core physics experimental programs called MISTRAL and BASALA from 1996 to 2002 in the EOLE critical facility of the Cadarache Center in collaboration with CEA. NUPEC also obtained a part of experimental data of the EPICURE program that CEA had conducted for 30 % Pu recycling in French PWRs. Japan Nuclear Energy Safety Organization(JNES) established in 2003 as an incorporated administrative agency took over the NUPEC's projects for nuclear regulation and has been implementing FUBILA program that is for high burn up BWR full MOX cores. This paper presents an outline of the programs and a summary of the analysis results of the criticality of those experimental cores with major nuclear data libraries.

Utilization of nuclear research reactors

Full text: Report on an IAEA interregional training course, Budapest, Hungary, 5-30 November 1979. The course was attended by 19 participants from 16 Member States. Among the 28 training courses which the International Atomic Energy Agency organized within its 1979 programme of technical assistance was the Interregional Training Course on the Utilization of Nuclear Research Reactors. This course was held at the Nuclear Training Reactor (a low-power pool-type reactor) of the Technical University, Budapest, Hungary, from 5 to 30 November 1979 and it was complemented by a one-week Study Tour to the Nuclear Research Centre in Rossendorf near Dresden, German Democratic Republic. The training course was very successful, with 19 participants attending from 16 Member States - Bangladesh, Bolivia, Czechoslovakia, Ecuador, Egypt, India, Iraq, Korean Democratic People's Republic, Morocco, Peru, Philippines, Spain, Thailand, Turkey, Vietnam and Yugoslavia. Selected invited lecturers were recruited from the USA and Finland, as well as local scientists from Hungarian institutions. During the past two decades or so, many research reactors have been put into operation around the world, and the demand for well qualified personnel to run and fully utilize these facilities has increased accordingly. Several developing countries have already acquired small- and medium-size research reactors mainly for isotope production, research in various fields, and training, while others are presently at different stages of planning and installation. Through different sources of information, such as requests to the IAEA for fellowship awards and experts, it became apparent that many research reactors and their associated facilities are not being utilized to their full potential in many of the developing countries. One reason for this is the lack of a sufficient number of trained professionals who are well acquainted with all the capabilities that a research reactor can offer, both in research and

The reactor safety R and D work of forschungszentrum karlsruhe (FZK) had been part of the nuclear safety research project (PSF) since 1990. In 2000, a new organisational structure was introduced and the Nuclear Safety Research Project was transferred into the nuclear safety research programme (NUKLEAR). In addition to the three traditional main topics - Light Water Reactor safety, Innovative systems, Studies related to the transmutation of actinides -, the new Programme NUKLEAR also covers Safety research related to final waste storage and Immobilisation of HAW. These new topics, however, will only be dealt with in the next annual report. Some tasks related to the traditional topics have been concluded and do no longer appear in the annual report; other tasks are new and are described for the first time. Numerous institutes of the research centre contribute to the work programme, as well as several external partners. The tasks are coordinated in agreement with internal and external working groups. The contributions to this report, which are either written in German or in English, correspond to the status of early/mid 2001. (orig.)

Dose assessments for Greifswald and Cadarache with new source terms from ITER NSSR-1

International Nuclear Information System (INIS)

Raskob, W.; Forschungszentrum Karlsruhe GmbH Technik und Umwelt; Hasemann, I.

1997-08-01

Probabilistic dose assessments for accidental atmospheric releases of various ITER source terms which contain tritium and/or activation products were performed for the sites of Greifswald, Germany, and Cadarache, France. No country specific rules were applied and the input parameters were adapted as far as possible to those used within former ITER studies to achieve a better comparability with site independent dose assessments performed in the frame of ITER. The calculations were based on source terms which, at the first time, contain a combination of tritium and activation products. This allowed a better judgement of the contribution of the individual fusion relevant materials to the total dose. The results were compared to site independent dose limits defined in the frame of ITER. Source terms for two different categories, representing 'extremely unlikely events' (CAT-IV) and 'hypothetical sequences' (CAT-V), were investigated. In no cases, the release scenarios of category CAT-IV exceeded the ITER limits. In addition, early doses from the hypothetical scenarios of type CAT-V were still below 50 mSv or 100 mSv, values which are commonly used as lower reference values for evacuation in many potential home countries of ITER. Only the banning of food products was found to be a potential countermeasure which may affect larger areas. (orig.) [de

Future of nuclear energy research

Fuketa, Toyojiro

In spite of the easing of worldwide energy supply and demand situation in these years, we believe that research efforts towards the next generation nuclear energy are indispensably necessary. Firstly, the nuclear colleagues believe that nuclear energy is the best major energy source from many points of view including the global environmental viewpoint. Secondly, in the medium- and long-range view, there will once again be a high possibility of a tight supply and demand situation for oil. Thirdly, nuclear energy is the key energy source to overcome the vulnerability of the energy supply structure in industrialized countries like Japan where virtually no fossil energy source exists. In this situation, nuclear energy is a sort of quasi-domestic energy as a technology-intensive energy. Fourthly, the intensive efforts to develop the nuclear technology in the next generation will give rise to a further evolution in science and technology in the future. A few examples of medium- and long-range goals of the nuclear energy research are development of new types of reactors which can meet various needs of energy more flexibly and reliably than the existing reactors, fundamental and ultimate solution of the radioactive waste problems, creation and development of new types of energy production systems which are to come beyond the fusion, new development in the biological risk assessment of the radiation effects and so on. In order to accomplish those goals it is quite important to introduce innovations in such underlying technologies as materials control in more microscopic manners, photon and particle beam techniques, accelerator engineering, artificial intelligence, and so on. 32 refs, 2 figs

This report describes the accomplishments in basic research in nuclear physics carried out by the theoretical nuclear physics group in the Department of Physics at the University of Texas at Austin, during the period of November 1, 1992 to October 31, 1993. The work done covers three separate areas, low-energy nuclear reactions, intermediate energy physics, and nuclear structure studies. Although the subjects are thus spread among different areas, they are based on two techniques developed in previous years. These techniques are a powerful method for continuum-random-phase-approximation (CRPA) calculations of nuclear response and the breakup-fusion (BF) approach to incomplete fusion reactions, which calculation on a single footing of various incomplete fusion reaction cross sections within the framework of direct reaction theories. The approach was developed as a part of a more general program for establishing an approach to describing all different types of nuclear reactions, i.e., complete fusion, incomplete fusion and direct reactions, in a systematic way based on single theoretical framework

Safety of Basic nuclear facilities (INB) other than electronuclear reactors. Lessons learned from declared significant events in 2011 and 2012

International Nuclear Information System (INIS)

2013-01-01

The first part of this report presents the different types of basic nuclear facilities other than electronuclear reactors. These installations can be industrial installations dedicated or not to the nuclear fuel cycle, research and support installations, be definitively stopped or being dismantled, or radioactive waste storage installations. After a comment of the main trends noticed in 2011 and 2012, the report proposes a transverse analysis of events which occurred in these installations. These events are related to various risks: dissemination of radioactive materials, exposure to ionizing radiations, criticality, fire and explosion, handling operations, loss of electric supplies or fluids, external aggression. Other events are those significant for the environment with a radiological component, or related to periodic controls and tests. The causes of these events are analysed. Specific events are presented which occurred on different sites (in the MELOX plant, in Areva sites in La Hague, Pierrelatte, in CEA sites in Cadarache and Saclay, in a fuel factory in Romans). Other topics are finally addressed: safety measures after the Fukushima accident, safety and radiation protection management systems of Areva and CEA, dismantling of nuclear installations

The PLINIUS experimental platform at CEA Cadarache is dedicated to the experimental study of nuclear reactor severe accidents thanks to experiments between 2000 and 3500 K with prototypic corium. Corium is the mixture that would be formed by an hypothetical core melting and its mixing with structural materials. Prototypical corium has the same chemical composition as the corium corresponding to a given accident scenario but has a different isotopic composition (use of depleted uranium,...). Research programs and test series have been performed to study corium thermophysical properties, fission product behaviour, corium spreading, solidification and interaction with concrete as well as its coolability. It was the frame of research training of many students and was realized within national, European and international collaborations. (author)

Challenges faced by nuclear research centres in Indonesia

Nuclear research centres in Indonesia are mainly owned and operated by the National Nuclear Energy Agency, covering basically various research and development facilities for non-energy and energy related activities. The research and development activities cover a broad spectrum of basic, applied, and developmental research involving nuclear science and technology in supporting various fields ranging from basic human needs, e.g. food and health; natural resources and nuclear and environmental safety; as well as industry. Recent economic crisis, triggered by monetary turmoil, has dictated the IAEA to face new challenges and to give more efforts on the application of the so called 'instant technology' i.e. the technology which has been developed and is ready for implementation, especially on food and health, to be better utilized to overcome various problems in the society. Various short and medium term programmes on the application of isotopes, radiation, and nuclear techniques for non-energy related activities have emerged in accord with these efforts. In this regard, besides the intensification of the instant technology implementation on food and health, the nuclear research and development on food plant mutation, fertilizers, radio-vaccines, production of meat and milk, production processes of various radiopharmaceuticals, and radioisotopes as well as radiation processing related to agro-industry have to be intensified using the available laboratories processing facilities. The possibility of the construction of irradiators for post harvesting processes in some provinces is being studied, while the designing and manufacturing of various prototypes of devices, equipment, and instruments for nuclear techniques in health and industry are continued. Considering the wide applications of accelerators for non-energy and energy related research and development, construction of accelerator-based laboratories is being studied. In energy related research the feasibility of

Nuclear research and development have been intensively pursued in West Germany by the Government and the Laender since 1955. In this period, the aims and official measures for fostering the research and use of nuclear power for peaceful purposes were laid down in four nuclear programmes. The 4th Nuclear Programme covers the period 1973 to 1976. From 1977, nuclear development became part of the energy research programme which was published by the West German Government in the spring of 1977. The basic nuclear research, however, was regarded as part of a total concept for fostering basic research (to be developed). While all the activities of research in the natural sciences and arts fostered by the West German Ministry of Research and Technology were to be co-ordinated in a more schematic form in the plan for 'Basic Research', it is the aim of the present statement to take stock of the present situation in 'Basic Nuclear Research' including the associated fields of 'Nuclear Solid Research' and 'Synchrotron Radiation', to analyse their structure, to describe the scientific aims for the next five years and to determine the total financial requirements. The basis for determining the financial programme worked out by the expert committee on 'Physical Research in the Nuclear Field' and the other committees in this field. The plans are in agreement with the medium term plan of the West German Ministry of Research and Technology (at 27.10.1977) and their contents correspond to the state of affairs at the end of 1977.

There were many interesting presentations of unique studies at the Annual Meeting of the Japanese Society of Nuclear Medicine, although there were fewer attendees from Europe than expected. These presentations included research on diseases that are more frequent in Japan and Asia than in Europe, synthesis of original radiopharmaceuticals, and development of imaging devices and methods with novel ideas especially by Japanese manufacturers. In this review, we introduce recent nuclear medicine research conducted in Japan in the five categories of Oncology, Neurology, Cardiology, Radiopharmaceuticals and Technology. It is our hope that this article will encourage the participation of researchers from all over the world, in particular from Europe, in scientific meetings on nuclear medicine held in Japan. (orig.)

Nuclear Energy Research in Europe

Schenkel, Roland; Haas, Didier

2008-01-01

The energy situation in Europe is mainly characterized by a growth in consumption, together with increasing import dependence in all energy resources. Assuring security of energy supply is a major goal at European Union level, and this can best be achieved by an adequate energy mix, including nuclear energy, producing now 32 % of our electricity. An increase of this proportion would not only improve our independence, but also reduce greenhouse gases emissions in Europe. Another major incentive in favor of nuclear is its competitiveness, as compared to other energy sources, and above all the low dependence of the electricity price on variation of the price of the raw material. The European Commission has launched a series of initiatives aiming at better coordinating energy policies and research. Particular emphasis in future European research will be given on the long-term sustainability of nuclear energy through the development of fast reactors, and to potential industrial heat applications.

As the nuclear industry moves into a new development phase, many facilities built in the fifties and sixties are reaching the end of their service life. Dismantling them and rehabilitating the sites on which they stand is a major industrial challenge which will give rise to a number of new projects. AREVA has more than 20 years' experience in these highly technical fields. As more and more sites reach the end of their service life, AREVA considers nuclear site value development as a fully-fledged industrial activity. The group's competencies in this field have been grouped together to form a dedicated entity: the Nuclear Site Value Development Business Unit, created in 2008. Several billion euros are invested in site value development projects which are far-reaching and complex, and often last for several decades. Long before work actually begins, lengthy studies and preparations are required to schedule operations, select the techniques to be used and optimize costs and deadlines. The Nuclear Site Value Development BU is currently working on four major projects involving its own facilities and those of the CEA: - La Hague: dismantling of the first generation of used fuel recycling facilities. Between 1966 and 1998, almost 5,000 tons of used fuel from graphite-moderated gas-cooled reactors, 4,500 tons of light water reactor fuel, as well as fuel from fast reactors and research reactors, were treated at UP2 400, the very first industrial recycling plant on the La Hague site. - Marcoule: first-time dismantling of a recycling plant. 1,000 rooms to be cleaned up, 30,000 tons of waste to be treated, 30 years of work. - Cadarache: first-time dismantling of a Mox fuel fabrication plant. The Cadarache plant was commissioned in 1962 to fabricate fuel for fast reactors; this was followed by MOX fuel for light water reactors, an activity which continued until the plant was shut down in 2003. - Annecy and Veurey: giving a new lease of life to former industrial sites

In the department of research reactor, many neutronics calculations have been performed to construct, to operate and to modify research reactors of JAERI with several kinds of nuclear data libraries. This paper presents latest two neutronic analyses on research reactors. First one is design work of a low enriched uranium (LEU) fuel for JRR-4 (Japan Research Reactor No.4). The other is design of a uranium silicon dispersion type (silicide) fuel of JRR-3M (Japan Research Reactor No.3 Modified). Before starting the design work, to estimate the accuracy of computer code and calculation method, experimental data are calculated with several nuclear data libraries. From both cases of calculations, it is confirmed that JENDL-3.2 gives about 1 %Δk/k higher excess reactivity than JENDL-3.1. (author)

General problems specific to hot nuclear materials research facilities

Bart, G.

1996-01-01

During the sixties, governments have installed hot nuclear materials research facilities to characterize highly radioactive materials, to describe their in-pile behaviour, to develop and test new reactor core components, and to provide the industry with radioisotopes. Since then, the attitude towards the nuclear option has drastically changed and resources have become very tight. Within the changed political environment, the national research centres have defined new objectives. Given budgetary constraints, nuclear facilities have to co-operate internationally and to look for third party research assignments. The paper discusses the problems and needs within experimental nuclear research facilities as well as industrial requirements. Special emphasis is on cultural topics (definition of the scope of nuclear research facilities, the search for competitive advantages, and operational requirements), social aspects (overageing of personnel, recruitment, and training of new staff), safety related administrative and technical issues, and research needs for expertise and state of the art analytical infrastructure

Policy makers in the developing countries tend to assess the value of any research project by its end-results. As research projects in the field of applied science or technology promise immediate and tangible benefits to the society, high priority is given to such projects in fund allocation by policy makers. On the other hand, basic or ''pure'' science is usually viewed as pursuit of knowledge for its own sake. It has been pointed out that such a view is a mistaken one and there is no real demarcation between basic science and applied science. More often than not, results of research in basic science form the basis of transforming old technologies into better ones and giving rise to new ones. On this background, a case has been emphatically put forward: (1) to identify areas of science, particularly in nuclear science, which may not appear relevant to the immediate problems but look promising in their application and (2) to make investments, even though heavy, for research in such areas. In case of nuclear science, research areas of potential application are high energy accelerators, implosion, fusion reactions, laser fusion, tokamak devices, fusion-fission hybrid reactor systems, breeding of fissile materials from fertile ones by accelerator based neutron sources. Impact of research in these areas on and its relevance to nuclear power generation is indicated and the-state-of-art in these areas in India is described. An appendix lucidly explains generation of nuclear energy from fission and discusses thermal and fast breeder reactors. (M.G.B.)

The field of scientific research goes through rapid changes to which organizations must dinamically and efficiently adapt, which leads to the need to develop a continuous learning process that should be the basis for a long-term operational performance. Thus, human resource management systems and continuous learning should be perfectly correlated/alligned with the organizational strategy and knowledge. The research institutes through the nature of their activity are constantly undergoing a transformation process by exploring new research areas which presumes ensuring competent human resources who have to continuously learn and improve. The «learning organization » concept represents a metaphor rooted in the search of a strategy for promoting the personal development of the individual within an organization through a continuous transformation. Learning is associated with the idea of continuous transformation based on the individual and organizational development. Within « learning organizations » the human development strategy occupies a central role in management strategies. It was learned that organizations which perform excellently depend on the employees committment, especially in the budget constraints environment. For this, the human resources have to be used at maximum capacity but this is possible only with an increased committment of the employee towards the organization. The purpose of this paper is to present the basic training programme for the new employees which is part of the training strategy which carry out activities in the nuclear field of SCN Pitesti. With the majority of the research personnel aged between 45 and 60 years old there is the risk of loosing the knowledge gained in this domain. The expertise gained by experienced experts in the institute nationally and internationally can be exploited through the knowledge transfer to the new employees by organizing training programmes. The knowledge transfer between generations is one of the

Nuclear energy continues to play a major role in the world's energy economy. Research and test reactors are an important component of a nation's nuclear power infrastructure as they provide training, experiments and operating experience vital to developing and sustaining the industry. Indeed, nations with aspirations for nuclear power development usually begin their programs with a research reactor program. Research reactors also are vital to international science and technology development. It is important to keep them safe from both accident and sabotage, not only because of our obligation to prevent human and environmental consequence but also to prevent corresponding damage to science and industry. For example, an incident at a research reactor could cause a political and public backlash that would do irreparable harm to national nuclear programs. Following the accidents at Three Mile Island and Chernobyl, considerable efforts and resources were committed to improving the safety posture of the world's nuclear power plants. Unsafe operation of research reactors will have an amplifying effect throughout a country or region's entire nuclear programs due to political, economic and nuclear infrastructure consequences.

Full development of nuclear energy has imposed a new role on nuclear energy centres. Nuclear technology for different reactor concepts is also now in a phase of high development. Several reactor concepts have been developed for industrial use and electric power production. Development of fast reactors is still under way and needs further research efforts. Having in mind these two main guidelines, research programmes in nuclear energy centres should be geared to the development of the activities vital to the implementation of national nuclear energy programmes. In this respect, national nuclear centres should devote their attention to three major tasks. First, to establish a background for the introduction of nuclear energy into the national energy system and to support a national safety system. Secondly, to support the national programme by skilled manpower, to provide the basic training in nuclear technology for future staff of nuclear power stations and to assist the universities in establishing the necessary educational programme in nuclear energy. Thirdly, to follow the development of nuclear energy technology for fast breeder reactor concepts. (author)

The strategic goal of the 5 th EURATOM RTD Framework Programme (FP5) is to help exploit the full potential of nuclear energy in a sustainable manner, by making current technologies even safer and more economical and by exploring promising new concepts. The programme covers nuclear fusion, nuclear fission and radiation protection. Part of the programme on nuclear fission and radiation protection is being implemented through ''indirect actions'', i.e. research co-sponsored (up to 50% of total costs) and co-ordinated by DG RESEARCH of the European Commission (EC) but carried out by external public and private organisations as multi-partner projects. The budget available for these indirect actions during FP5 (1998-2002) is 191 MEuro. The programme covers four different areas: safety of existing reactors, including plant life management, severe accident management and development of evolutionary systems; safety of the fuel cycle, including radioactive waste management and disposal, partitioning and transmutation and decommissioning of nuclear installation; safety of future systems, including new or revisited reactor or fuel cycle concepts; radiation protection and radiological sciences, including both basic radiobiology and radiophysics and issues connected to the application of radiation protection. After the first calls for proposals of FP5, which were evaluated in 1999 about 140 research projects have been selected for funding and is now in the process of starting. In parallel the research projects that were supported in the 4th Framework Programme (1994 - 1998) are coming to an end, and being reported, at the same time as the first thoughts on the 6 t h FP are discussed.An important new component for the future research in Europe is the concept of a European Research Area (ERA). The purpose of ERA is to create better overall framework conditions for research in Europe. Some of the concepts being discussed in this context are networking of centres of excellence, a

Nuclear medicine research: an evaluation of the ERDA program

International Nuclear Information System (INIS)

1976-08-01

Legislation which established the Energy Research and Development Administration (ERDA) January 19, 1975, stipulated that this new agency should be responsible for all activities previously assigned to the Atomic Energy Commission (AEC) and not specifically assigned to other agencies. Such activities included the nuclear medicine research program of the AEC Division of Biomedical and Environmental Research (DBER). To determine whether continuation of this program under the broader ERDA mission of energy-related research was in fact appropriate, a special task force was appointed in January 1975 by Dr. James L. Liverman, the director of DBER. This task force, comprised of established scientists knowledgeable about issues related to nuclear medicine either currently or in the past, was charged specifically to assess the historical impact of the AEC/ERDA nuclear medicine program on the development of nuclear medicine, the current status of this program, and its future role within the structure of ERDA. The specific recommendations, in brief form, are as follows: the federal government should continue to support the medical application of nuclear technology; ERDA should retain primary responsibility for support and management of federal nuclear medicine research programs; and management and emphasis of the ERDA nuclear medicine program require modification in certain areas, which are set forth

Morocco has a long and rich history in nuclear technology which began in the 1950s with the development of nuclear techniques in several important socio-economic fields such as medicine, agriculture and industrial applications. The development of nuclear technology evolved over various organizations, primarily within the Ministry of Education. However, with the formation of the National Centre for Nuclear Energy and Technology (CNESTEN) the development of nuclear technology in Morocco has been reinforced. Morocco is looking forward and actively pursuing alternative sources of energy and has a very strong interest in nuclear power generation and associated technologies such as nuclear desalination. Entry into these new technologies is required since there are no natural sources of energy, Morocco currently imports most of its energy needs from abroad and has a rapidly expanding energy need. In this paper, we present CNESTEN and its main facilities, missions, research programmes, human resources, training, education, national and international cooperation, etc

An accelerator laboratory is presently under construction in Sofia at the Institute for Nuclear Research and Nuclear Energy. The laboratory will use a TR24 type of cyclotron, which provides a possibility to accelerate a proton beam with an energy of 15 to 24 MeV and current of up to 0.4 mA. An accelerator with such parameters allows to produce a large variety of radioisotopes for development of radiopharmaceuticals. The most common radioisotopes that can be produced with such a cyclotron are PET isotopes like: 11C, 13N, 15O, 18F, 124I, 64Cu, 68Ge/68Ga, and SPECT isotopes like: 123I, 111In, 67Ga, 57Co, 99mTc. Our aim is to use the cyclotron facility for research in the fields of radiopharmacy, radiochemistry, radiobiology, nuclear physics, materials sciences, applied research, new materials and for education in all these fields including nuclear energy. Presently we perform investigations in the fields of target design for production of radioisotopes, shielding and radioprotection, new ion sources etc.

A comprehensive Nuclear Plant Aging Research (NPAR) Program was implemented by the US NRC office of Nuclear Regulatory Research in 1985 to identify and resolve technical safety issues related to the aging of systems, structures, and components in operating nuclear power plants. This is Revision 2 to the Nuclear Plant Aging Research Program Plant. This planes defines the goals of the program the current status of research, and summarizes utilization of the research results in the regulatory process. The plan also describes major milestones and schedules for coordinating research within the agency and with organizations and institutions outside the agency, both domestic and foreign. Currently the NPAR Program comprises seven major areas: (1) hardware-oriented engineering research involving components and structures; (2) system-oriented aging interaction studies; (3) development of technical bases for license renewal rulemaking; (4) determining risk significance of aging phenomena; (5) development of technical bases for resolving generic safety issues; (6) recommendations for field inspection and maintenance addressing aging concerns; (7) and residual lifetime evaluations of major LWR components and structures. The NPAR technical database comprises approximately 100 NUREG/CR reports by June 1991, plus numerous published papers and proceedings that offer regulators and industry important insights to aging characteristics and aging management of safety-related equipment. Regulatory applications include revisions to and development of regulatory guides and technical specifications; support to resolve generic safety issues; development of codes and standards; evaluation of diagnostic techniques; (e.g., for cables and valves); and technical support for development of the license renewal rule. 80 refs., 25 figs., 10 tabs

The Russian Federation Ministry for Atomic Energy (MINATOM) and the US Department of Energy (USDOE) have formed International Nuclear Safety Centers to collaborate on nuclear safety research. USDOE established the US Center (ISINSC) at Argonne National Laboratory (ANL) in October 1995. MINATOM established the Russian Center (RINSC) at the Research and Development Institute of Power Engineering (RDIPE) in Moscow in July 1996. In April 1998 the Russian center became a semi-independent, autonomous organization under MINATOM. The goals of the center are to: Cooperate in the development of technologies associated with nuclear safety in nuclear power engineering; Be international centers for the collection of information important for safety and technical improvements in nuclear power engineering; and Maintain a base for fundamental knowledge needed to design nuclear reactors. The strategic approach is being used to accomplish these goals is for the two centers to work together to use the resources and the talents of the scientists associated with the US Center and the Russian Center to do collaborative research to improve the safety of Russian-designed nuclear reactors. The two centers started conducting joint research and development projects in January 1997. Since that time the following ten joint projects have been initiated: INSC databases--web server and computing center; Coupled codes--Neutronic and thermal-hydraulic; Severe accident management for Soviet-designed reactors; Transient management and advanced control; Survey of relevant nuclear safety research facilities in the Russian Federation; Computer code validation for transient analysis of VVER and RBMK reactors; Advanced structural analysis; Development of a nuclear safety research and development plan for MINATOM; Properties and applications of heavy liquid metal coolants; and Material properties measurement and assessment. Currently, there is activity in eight of these projects. Details on each of these

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)

Desgranges, L.; Pasquet, B.; Rasser, B.

2002-01-01

A shielded SIMS 6f has been installed in the LECA in 1999 and will examine nuclear fuels before the end of this year. Meanwhile several studies have been realised to test its technical performance for nuclear materials analysis. After a brief presentation of the design of the shielded SIMS, five examples of preliminary results will be underlined. In the nuclear field, SIMS is currently used for the analysis of Zircaloy cladding corrosion because it can detect light elements like boron or lithium. More than a quantitative measurement of isotopes, it was possible with our SIMS to produce a two dimension image of the corrosion layer focusing on the protective layer. SIMS has also the advantage to detect isotopes with a low concentration. This property will be enlightened with some results obtained on sulphur in UO 2 . Because SIMS uses the erosion of the sample surface, it is possible to make depth profile. This possibility will be demonstrated on water altered glass samples on which the altered layer will be evidenced on depth profile. The last application of SIMS presented in the paper is addressed to nuclear fuel with detection of xenon. Fission gases release is indeed of first importance for nuclear fuel because it affects fuel swelling, rod internal pressure, fuel thermal conductivity via the formation of pores etc. We have demonstrated that it was possible to measure xenon on an unirradiated UO 2 sample implanted with xenon. It was also proved that xenon could be measured in gaseous state, which would make possible the measurement of xenon filling pores. (author)

2008-07-01

South Africa recently made public its rather ambitious goals pertaining to nuclear energy developments in a Draft Policy and Strategy issued for public comment. Not much attention was given to an important tool for nuclear energy research and development, namely a well equipped and maintained research reactor, which on its own does not do justice to its potential, unless it is fitted with all the ancillaries and human resources as most first world countries have. In South Africa's case it is suggested to establish at least one Nuclear Energy Research and Development Centre at such a research reactor, where almost all nuclear energy related research can be carried out on par with some of the best in the world. The purpose of this work is to propose how this could be done, and motivate why it is important that it be done with great urgency, and with full involvement of young professionals, if South Africa wishes to face up to the challenges mentioned in the Draft Strategy and Policy.

1976-01-01

As a consequence of the decision of choosing light water reactors (PWR) for the French nuclear plants of the next ten years, a large safety program has been launched referring to three physical barriers against fission product release: the fuel element cladding, main primary system boundary and the containment. The parallel development of French-designed fast breeder reactors involved safety studies on: sodium boiling, accidental fuel behavior, molten fuel-sodium interaction, core accident and protection, and external containment. The rapid development of nuclear energy resulted in a corresponding development of safety studies relating to nuclear fuel facilities. French regulations also required a special program to be developed for the realistic evaluation of the consequences of external agressions, the French cooperation to multinational safety research being also intensive

Third, to follow the development of nuclear energy technology for the fast breeder reactor concepts. This paper describes some experience in introducing a new programme to the national nuclear energy centers in Yugoslavia. Recently, Yugoslavia has started building its first nuclear power station. Further introduction of nuclear power stations in the national electric energy system is also planned. This implies the need to reconsider the current nuclear energy programme in the nuclear energy centers. It has been decided to evaluate past experience and further needs for research activities regarding the nuclear power programme. Yugoslavia has three main nuclear energy centers whose activities are devoted to the development of national manpower in the field of nuclear sciences. Besides these three organizations, there are several others whose activities are concentrated on specific tasks in nuclear technology. In the

The roots of the current Nordic Nuclear Safety Research (NKS) programme can be traced back to the recommendation by the Nordic Council in the late 1950s for the establishment of joint Nordic committees on the issues of nuclear research and radiation protection. One of these joint Nordic committees, the 'Kontaktorgan', paved the way over its 33 years of existence for the future of Nordic cooperation in the field of nuclear safety, through the formation of Nordic groups on reactor safety, nuclear waste and environmental effects of nuclear power in the late 1960s and early 1970s. With an increased focus on developing nuclear power in the wake of the energy crisis on the 1970s, the NKS was established by the Nordic Council to further develop the previous strands of Nordic cooperation in nuclear safety. NKS started its first programme in 1977, funding a series of four year programmes over the next 24 years covering the areas of reactor safety, waste management, emergency preparedness and radioecology. Initially funded directly from the Nordic Council, ownership of NKS was transferred from the political level to the national competent authorities at the beginning of the 1990s. This organizational and funding model has continued to the present day with additional financial support from a number of co-sponsors in Finland, Norway and Sweden. (orig.)

This paper describes the principle and features of nuclear fusion using laser, as well as its basic concepts such as high-temperature / high-density implosion system and fast ignition of fuel. At present, researches aiming at nuclear fusion ignition have been developing. As the current state of researches, this paper reviews the situations of FIREX (Fast Ignition Realization Experiment) project of Japan focusing on direct irradiation implosion and fast ignition system, as well as NIF (National Ignition Facility) project of the U.S. aiming at ignition combustion based on indirect irradiation implosion and central ignition system. In collaboration with the National Institute for Fusion Science, Osaka University started FIREX-1 project in 2003. It built a heating laser LFEX of 10 kJ/1 to 10ps, and started an implosion/heating integration experiment in 2009. Currently, it is developing experiment to achieve heating to 5 keV. At NIF, the self-heating of central sparks via energy of α particles generated in the nuclear fusion reaction has been realized. This paper also overviews R and D issues surrounding the lasers for reactors for use in laser nuclear fusion power generators. (A.O.)

In Czech Republic 3 research and testing nuclear reactors are operated at present time, with the biggest one being the Nuclear Research Institute (NRI) reactor LVR-15, operated with maximum power 10 MW. This reactor serves as a radiation source for material testing, producing of ionizing radiation sources, theoretical studies, and, most recently, for boron neutron capture therapy. Another NRI reactor LR-0 is a reactor of zero power used mainly for the studies of WWER 1000 spent fuel criticality. For training of students the reactor called VRABEC (VR-1), operated also with very low power, serves since 1990 at the Faculty of Nuclear Engineering, of Czech Technical University. The similar testing type reactor (SR-0), already decommissioned, was also used since 1974 to 1989 in Skoda, Nuclear Machinery, Plzen. This contribution summarizes the present state of the spent fuel (SF) management of these nuclear reactors. As the SF management is different for very low or zero power reactors and power reactors, the first type will be only briefly discussed, and then the main attention will be devoted to SF management of the NRI experimental reactor LVR-15

Collective statement on the role of research in a nuclear regulatory context

International Nuclear Information System (INIS)

2001-01-01

In the present context of deregulation and privatisation of the nuclear industry, maintaining an adequate level of nuclear safety research is a primary concern for nuclear regulators, researchers and nuclear power plant licensees, as well as for government officials and the public. While these different stakeholders may have common concerns and interests, there may also be differences. At the international level, it is important to understand that divisions exist both within and among countries, not only in national cultures but also in the way regulators, researchers and licensees view the rote of research. An international gathering under the auspices of the OECD Nuclear Energy Agency (NEA) took place in June 2001, bringing together heads of nuclear regulatory bodies of NEA Member countries, senior regulators, senior executives of research organisations and leaders from the nuclear industry to discuss their perceptions of the rote of research in a nuclear regulatory context. This collective statement represents an international consensus on a rationale for regulatory research for currently operating nuclear reactors and for future reactors, and sets forth specific recommendations to NEA standing technical committees and Member countries. The intended audience is primarily nuclear safety regulators, senior researchers and industry leaders. Government authorities, nuclear power plant operators and the general public may also be interested. (author)

The United States is facing unprecedented challenges in climate change and energy security. President-elect Obama has called for a reduction of CO2 emissions to 1990 levels by 2020, with a further 80% reduction by 2050. Meeting these aggressive goals while gradually increasing the overall energy supply requires that all non-emitting technologies must be advanced. The development and deployment of nuclear energy can, in fact, help the United States meet several key challenges: (1) Increase the electricity generated by non-emitting sources to mitigate climate change, (2) Foster the safe and proliferation-resistant use of nuclear energy throughout the world, (3) Reduce the transportation sector's dependence on imported fossil fuels, and (4) Reduce the demand on natural gas for process heat and hydrogen production. However, because of the scale, cost, and time horizons involved, increasing nuclear energy's share will require a coordinated research effort-combining the efforts of industry and government, supported by innovation from the research community. This report outlines the significant nuclear energy research and development (R and D) necessary to create options that will allow government and industrial decision-makers to set policies and create nuclear energy initiatives that are decisive and sustainable. The nuclear energy R and D strategy described in this report adopts the following vision: Safe and economical nuclear energy in the United States will expand to address future electric and non-electric needs, significantly reduce greenhouse gas emissions and provide energy diversity, while providing leadership for safe, secure and responsible expansion of nuclear energy internationally

ITER (Latin: the way) is the acronym of a new international large research facility gradually taking shape after the meeting of Gorbachev and Reagan in Reykjavik in 1985. Under the auspices of the IAEA, worldwide scientific and industrial cooperation with 'home teams' of each of the ITER partners began at that time which were commissioned to accumulate the knowledge and the technology of nuclear fusion in the participating countries. At the end of the preparation and decisionmaking process, the design draft of the ITER reactor was elaborated in international cooperation as the basis of the ITER Convention. After lengthy negotiations among the international ITER partners, a European site for the ITER organization and its reactor was found at Cadarache, France. As the first ITER member, Europe now initiated worldwide cooperation in research and development, seeking to demonstrate the technical and scientific feasibility of tapping fusion power for peaceful purposes. The Council of the European Union (competitiveness), at its meeting on September 25, 2006, decided to sign the ITER Convention about the establishment of the International ITER Fusion Energy Organization ('ITER Organization') and about the mutual obligation to make the necessary contributions towards the construction of ITER.

Research achievements in Bangladesh agriculture using nuclear techniques

International Nuclear Information System (INIS)

Sattar, M.A.

1997-01-01

Application of isotope and radiation techniques in Bangladesh agriculture has been initiated in 1961 with the establishment of Atomic Energy Agricultural Research Centre, Dhaka under the then Pakistan Atomic Energy Commission. The activity of the centre was strengthened and upgraded to the level of an institute as a constituent organization of Bangladesh Atomic Energy Commission in 1972. It was further reorganized, made an autonomous research organization under the Ministry of Agriculture in 1982 and renamed as Bangladesh Institute of Nuclear Agriculture. The other organizations involved in nuclear agricultural research are Institute of Food and Radiation Biology and Bangladesh Agricultural University. A number of technologies have been developed using nuclear techniques that imparted on agricultural development. Sixteen new crops were developed using physical (200-700 Gy gamma rays) and chemical mutagen (NaN 3 ). Soil fertility and plant nutrition technologies were developed using both stable and radio isotopes. The improved feeding strategies and utilization of locally available low quality feed material (rice straw) were determined using 51 Cr-EDTA and 125 I in order to have better livestock growth and reproduction ability. Several constraints related to nuclear research were identified. Increased government commitment and international cooperation are of the utmost importance for effective utilization of the benefits of nuclear technology and to face the increasing demand for food for the ever increasing population in years to come

Seismological studies carried out by the CEA in connection with the safety of nuclear sites

Barbreau, A.; Ferrieux, H.; Mohammadioun, B.

1975-01-01

In order to evaluate the seismic risk at nuclear sites, the Department of Nuclear Safety of the French Atomic Energy Commission (CEA) has been conducting a programme of seismological studies for several years past. This programme is aimed at acquiring a better knowledge of seismic phenomena, in particular the spectral distribution of the energy of earthquakes, considered to be the only correct approach to the problem of earthquake protection, as well as a better knowledge of the seismic activity of the areas surrounding nuclear sites. The authors propose defining the design spectrum of the site on the basis of the probable energy at the source, the distance from the epicentre and the transfer function of the geological formations. The need - for the purpose of defining this spectrum - to acquire data on the characteristics of French earthquakes and on regional seismicity led the Department of Nuclear Safety to set up a network of seismic stations. It now has an observatory at the Cadarache Nuclear Research Centre and mobile stations with automatic magnetic recording for studying aftershock sequences and the activity of faults in the vicinity of nuclear sites, and for making the measurements necessary to calculate the transfer functions. With this equipment it was possible to record six aftershocks of the Oleron earthquake on 7 September 1972 close to the epicentre, and to calculate the spectra therefrom. The latter contained a lot of high frequencies, which is in agreement with the data obtained from other sources for earthquakes of low energy. The synthetic spectra calculated on the basis of one magnitude and one distance are in good agreement with the spectra obtained experimentally

Status of nuclear regulatory research and its future perspectives

Lee, J. I.; Kim, W. S.; Kim, M. W.

1999-01-01

A comprehensive investigation of the regulatory research comprising an examination of the research system, its areas and contents, and the goals and financial resources is undertaken. As a result of this study, the future direction of regulatory research and its implementation strategies are suggested to resolve the current issues emerging from this examination. The major issues identified in the study are; (a) an insufficient investment in nuclear regulatory and safety research, (b) an interfacial discrepancy between similar research areas, and (c) a limitation of utilizing research results. To resolve these issues, several measures are proposed : (1) developing a lead project to establish a comprehensive infrastructure for enhancing research cooperation between nuclear organizations including institutes, industry, and universities, with an aim to improve cooperation between projects and to strengthen overall coordination functions among research projects, (2) introducing a certification system on research outcome to promote the proliferation of both research results themselves and their application with a view to enhancing the research quality, (3) strengthening the cooperative system to promote the international cooperative research, and (4) digitalizing all documents and materials relevant to safety and regulatory research to establish KIMS (knowledge and information based management system). It is expected that the aforementioned measures suggested in this study will enhance the efficiency and effectiveness of both nuclear regulatory and safety research, if they are implemented after deliberating with the government and related nuclear industries in the near future

Applications of nuclear techniques and research 1990

International Nuclear Information System (INIS)

1990-01-01

The application of nuclear techniques, i.e. those techniques where use is made of isotopes and radiation, continues to contribute to progress in science, technology, agriculture, industry and medicine. Nuclear applications found their way into the IAEA's activities from the very beginning, and their promotion constitutes today a substantial fraction of the IAEA's Technical Co-operation and Research Contract Programmes. The 1990 selection is opened by a review of the role and function of the IAEA's Research Contract Programme, which is one of the Agency's most effective tools for promoting and developing nuclear applications. Applications in agriculture are covered in two articles dealing respectively with issues affecting the acceptance of food irradiation by governments, the food industry and consumers and with the use of radiation to induce plant mutation, a practical tool available to plant breeders in their effort to develop better quality crops. The following article deals with a typical nuclear application in medicine, i.e. the use of radionuclides in the diagnosis of lung diseases and in investigations related to the respiratory function. The use of environmental isotopes to assess the energy potential of geothermal fields is the next subject, a good example of nuclear methods applied to the evaluation of natural resources. The 1990 review concludes with a presentation prepared by the Third World Academy of Sciences on magnetic fusion research activity in the developing countries and its connection with the IAEA's own fusion programme

Research and test facilities required in nuclear science and technology

International Nuclear Information System (INIS)

2009-01-01

Experimental facilities are essential research tools both for the development of nuclear science and technology and for testing systems and materials which are currently being used or will be used in the future. As a result of economic pressures and the closure of older facilities, there are concerns that the ability to undertake the research necessary to maintain and to develop nuclear science and technology may be in jeopardy. An NEA expert group with representation from ten member countries, the International Atomic Energy Agency and the European Commission has reviewed the status of those research and test facilities of interest to the NEA Nuclear Science Committee. They include facilities relating to nuclear data measurement, reactor development, neutron scattering, neutron radiography, accelerator-driven systems, transmutation, nuclear fuel, materials, safety, radiochemistry, partitioning and nuclear process heat for hydrogen production. This report contains the expert group's detailed assessment of the current status of these nuclear research facilities and makes recommendations on how future developments in the field can be secured through the provision of high-quality, modern facilities. It also describes the online database which has been established by the expert group which includes more than 700 facilities. (authors)

1993-01-01

The story of the first decade of the nuclear research in Strasbourg includes three different periods. During the war there is the installation as part of the Reichsuniversitaet Strassburg (november 1941-november 1944) of one 'Medical Research Institute' the physics department of which is equipped with a very important equipment for the period, particularly a connection generator of 1.5 MeV. For the Liberation, the civil hospices and the Strasbourg Medicine Faculty decide to create from the old german installations an artificial radioisotope production laboratory: the 'Strasbourg Nuclear Research Institute' (N.R.I) which was born in 1947 as interfaculty Institute (Medicine, Science, Pharmacy). But the N.R.I doesn't make for the applied research but for the fundamental research. To the nuclear research institute will be added in 1950 the corpuscular physics and the nuclear chemistry laboratories. 163 refs., 20 figs

Goethem, G. van

2004-01-01

In this invited lecture, research and training in nuclear fission are looked at from a European perspective with emphasis on the three success factors of any European policy, namely: common needs, vision and instruments, that ought to be strongly shared amongst the stakeholders across the Member States concerned. As a result, the following questions are addressed: What is driving the current EU trend towards more research, more education and more training, in general? Regarding nuclear fission, in particular, who are the end-users of Euratom 'research and training' and what are their expectations from EU programmes? Do all stakeholders share the same vision about European research and training in nuclear fission? What are the instruments proposed by the European Commission (EC) to conduct joint research programmes of common interest for the nuclear fission community? In conclusion, amongst the stakeholders in Europe, there seems to be a wide consensus about common needs and instruments, but not about a common vision regarding nuclear. (author)

This paper presents a quantitative analysis of research trends in the fields of plasma physics and nuclear fusion. This analysis is based on information retrieval from available data bases such as INSPEC tapes. The results indicate that plasma physics research is now in the maturation phase of its life cycle, and that nuclear fusion research is in its growth phase. This paper indicates that there is a correlation between the number of accumulated papers in the fields of plasma physics and nuclear fusion and the experimentally attained values of the plasma ignition parameter ntT. Using this correlation ''research effort curve'', we forecast that the scientific feasibility of controlled fusion using magnetic confinement systems will be proved around 1983. (author)

The Institute for Nuclear Research and Nuclear Energy is the biggest one within Bulgarian Academy of Sciences and it is a leading complex center for research and application of the nuclear physics in Bulgaria. The year 2003 was the first for the functioning of the new organization structure of INRNE consisting of 26 laboratories and 4 scientific experimental bases joined according their thematic in 7 scientific directions governed by the correspondent Expert Councils and Specialised Seminars. The scientific staff of the Institute has been worked on about 104 problems during the 2003 mainly on our traditional scientific areas, in particular, in the field of: theory of the elementary particles, field theory, atomic nuclei and quantum phenomena; experimental physics of the elementary particles, nuclear reactions, structure of atomic nuclei, cosmic rays and gamma-astrophysics at ultra high energies; neutron interactions and cross sections, physics of the fission; reactor physics, nuclear energy and nuclear safety and security ect. Now the results are already present and, as can been seen, almost half of the developments are connected with the problems of scientific support of the national nuclear energy production, radioactive waste, monitoring and management of the environment. With few exceptions, all these tasks are financially supported by national, foreign and international organizations. The fundamental end applied research results for 2003 have been accepted for publication or published in more than 300 articles in journals and proceeding of many international conferences. Large amount of these results has been obtained in close collaboration with international and foreign research centers, universities and institutions. Essential progress was obtained by the modernization of the scientific experimental bases of INRNE. The technical design project for the reconstruction of the old research reactor IRT 2000 in the new IRT 200 was successfully finished. The

Vuori, S.

2000-06-01

According to the Finnish nuclear energy legislation, each producer of nuclear waste is responsible for the safe handling, management and disposal of the waste as well as for the arising costs. Authorities supervise and control the implementation of the national waste management programme and set the necessary safety and other requirements. In these tasks the authorities are supported by a research programme on nuclear waste management that is independent of the implementing organisations and power companies. The main objective of the research programme has been to provide the authorities with information and research results relevant for the safety of nuclear waste management. The main emphasis in this research programme has been devoted to the final disposal of spent fuel. The whole area of the research programme has been subdivided into the following main topic areas: (1) Behaviour of bedrock (2) Geohydrology and geochemistry, (3) Release of radionuclides from repository and subsequent transport in bedrock, (4) Engineered safety barriers of the repository, system, (5) Performance and safety assessment of spent fuel disposal facilities, (6) Waste management technology and costs (7) Evaluation of the contents and scope of and observation of the realisation of the environmental impact assessment procedure for the siting of spent nuclear fuel disposal facility, and research on other societal and sociopolitical issues, and (8) Public information, attitude, and image issues for waste management facilities. The research programme has generated considerably increased information on the behaviour of the natural and technical release barriers of the disposal system and thereby contributed to building of confidence on the long-term safety of geological disposal of spent fuel. Furthermore, increased confidence among the public in the affected candidate municipalities has probably been achieved by the complementary studies conducted within the research programme on topics

Application of isotope and radiation techniques in Bangladesh agriculture has been initiated in 1961 with the establishment of Atomic Energy Agricultural Research Centre, Dhaka under the then Pakistan Atomic Energy Commission. The activity of the centre was strengthened and upgraded to the level of an institute as a constituent organization of Bangladesh Atomic Energy Commission in 1972. It was further reorganized, made an autonomous research organization under the Ministry of Agriculture in 1982 and renamed as Bangladesh Institute of Nuclear Agriculture. The other organizations involved in nuclear agricultural research are Institute of Food and Radiation Biology and Bangladesh Agricultural University. A number of technologies have been developed using nuclear techniques that imparted on agricultural development. Sixteen new crops were developed using physical (200-700 Gy gamma rays) and chemical mutagen (NaN{sub 3}). Soil fertility and plant nutrition technologies were developed using both stable and radio isotopes. The improved feeding strategies and utilization of locally available low quality feed material (rice straw) were determined using {sup 51}Cr-EDTA and {sup 125}I in order to have better livestock growth and reproduction ability. Several constraints related to nuclear research were identified. Increased government commitment and international cooperation are of the utmost importance for effective utilization of the benefits of nuclear technology and to face the increasing demand for food for the ever increasing population in years to come 32 refs., 1 tab.

Managing nuclear safety research facilities and capabilities in a changing nuclear industry: the contribution of the OECD/NEA

International Nuclear Information System (INIS)

Royen, J.

2000-01-01

Although the safety level of nuclear power plants in OECD countries is very satisfactory and the technologies basic to the resolution of safety issues have advanced considerably, continued nuclear safety research work is necessary to address many of the residual concerns, and it remains an important element in ensuring the safe operation of nuclear power plants. However, the funding levels of national Government safety research programmes have been reduced over recent years. There is concern about the ability of OECD Member countries to sustain an adequate level of nuclear safety research capability. The OECD/NEA has a key role to play in organizing reflection and exchange of information on the most efficient use of available technical resources, and in the international management of nuclear safety research facilities and capabilities in a changing nuclear industry. Possible initiatives are mentioned in the paper. (author)

After the events at the Japanese nuclear power plant of Fukushima Daiichi, the German federal government decided that Germany will give up electricity generation from nuclear power within a decade. The last reactor will be disconnected from the power grid in 2022. Helping to make this opt-out as safe as possible is one of the duties of the Helmholtz Association with its Nuclear Safety Research Program within the Energy Research Area. Also the demolition of nuclear power plants and the repository problem will keep society, and thus also research, busy for a number of decades to come. Giving up electricity production from nuclear power thus must not mean giving up the required nuclear technology competences. In the fields of reactor safety, demolition, final storage, radiation protection, and crisis management, in critical support of international developments, and for competent evaluation of nuclear facilities around Germany, these competences will be in demand far beyond the German opt-out. This is the reason why the final report by the Ethics Committee on 'Safe Energy Supply' emphasizes the importance of nuclear technology research. Close cooperation on national, European and international levels is indispensable in this effort. Also nuclear safety research in the Helmholtz Association is aligned with the challenges posed by the opt-out of the use of nuclear power. It is important that the high competences in the areas of plant safety and demolition, handling of radioactive waste, and safe final storage as well as radiation protection be preserved. The Nuclear Safety Research Program within the Energy Research Area of the Helmholtz Association therefore will continue studying scientific and technical aspects of the safety of nuclear reactors and the safety of nuclear waste management. These research activities are provident research conducted for society and must be preserved for a long period of time. The work is closely harmonized with the activities

In 2015, South East Asian Countris are entering into the social, economic and security partnership. Nuclear Research and Development undoubtedly has important roles in all three pillars. Nuclear applications that are being realised in the region ranges from energy, mrdical to agricultural application.In this new era of cooperation, we are seeking for technologies that lead to solution to improve our ways of living. As all other research and development nuclear research has been carried out in all countries in the region. However, it does have its critiques on safety issues based on people capability in the region. In order to make progress in research and development, human resource development is the key fundamental to its sucess. An experience of regional collaboration in developing pulsed neutron souurce is presented as an example. The research had been revived though collaoration of different research laboratories within ASEAN countries with support of Asian African Assosiation for Plasma Training (AAAPT). The 'low cost research theme' has fundamentally set up a platform for more future advanced research for fusion and for local industrial applications. It also increases experimental and theoretical research awareness among new generations that could be carried out in local laboratories. A device such as UNU-ICPT Plasma Focus has been explored, and it has been built, studied; both theoretical and experimental; and used for many different kind of applications.

The researches carried out since many years on nuclear wastes have led to two main ways of management: the long-term conditioning of radio-elements and their advanced separation. The French atomic energy commission (CEA) has chosen to take up also the transmutation challenge, a way to transform long-living radioactive wastes into short-living radioactive wastes or stable compounds. The transmutation programs are based both on simulation and experiments with a huge international collaboration. This dossier presents in a digest way the research activity carried out on nuclear wastes processing and management at the CEA. (J.S.)

2015-01-01

Using a vertical education enhancement model, a Nuclear Education and Research Vertical Enhancement (NERVE) program was developed. The NERVE program is aimed at developing nuclear engineering education and research to 1) enhance skilled workforce development in disciplines relevant to nuclear power, national security and medical physics, and 2) increase the number of students and faculty from underrepresented groups (women and minorities) in fields related to the nuclear industry. The program uses multi-track training activities that vertically cut across the several education domains: undergraduate degree programs, graduate schools, and post-doctoral training. In this paper, we present the results of an integrative curriculum development in the NERVE program. The curriculum development began with nuclear content infusion into existing science, engineering and technology courses. The second step involved the development of nuclear engineering courses: 1) Introduction to Nuclear Engineering, 2) Nuclear Engineering I, and 2) Nuclear Engineering II. The third step is the establishment of nuclear engineering concentrations in two engineering degree programs: 1) electrical engineering, and 2) mechanical engineering. A major outcome of the NERVE program is a collaborative infrastructure that uses laboratory work, internships at nuclear facilities, on-campus research, and mentoring in collaboration with industry and government partners to provide hands-on training for students. The major activities of the research and education collaborations include: - One-week spring training workshop at Brookhaven National Laboratory: The one-week training and workshop is used to enhance research collaborations and train faculty and students on user facilities/equipment at Brookhaven National Laboratory, and for summer research internships. Participants included students, faculty members at Alabama A and M University and research collaborators at BNL. The activities include 1) tour and

Data base on nuclear power plant dose reduction research projects

Khan, T.A.; Baum, J.W.

1986-10-01

Staff at the ALARA Center of Brookhaven National Laboratory have established a data base of information about current research that is likely to result in lower radiation doses to workers. The data base, concerned primarily with nuclear power generation, is part of a project that the ALARA Center is carrying out for the Nuclear Regulatory Commission. This report describes its current status. A substantial amount of research on reducing occupational exposure is being done in the US and abroad. This research is beginning to have an impact on the collective dose expenditures at nuclear power plants. The collective radiation doses in Europe, Japan, and North America all show downward trends. A large part of the research in the US is either sponsored by the nuclear industry through joint industry organizations such as EPRI and ESEERCO or is done by individual corporations. There is also significant participation by smaller companies. The main emphasis of the research on dose reduction is on engineering approaches aimed at reducing radiation fields or keeping people out of high-exposure areas by using robotics. Effective ALARA programs are also underway at a large number of nuclear plants. Additional attention should be given to non-engineering approaches to dose reduction, which are potentially very useful and cost effective but require quantitative study and analysis based on data from nuclear power plants. 9 refs., 1 fig.

This report gives an overview of the present status of nuclear activities in Switzerland. It indicates and comments the shares of the different sources of production of electricity, the electricity consumption, and electricity imports. It describes the structure of the sector. It proposes a history of nuclear development (first reactors, accidents, abandoned projects), describes the present nuclear plant stock, and the fuel cycle management (supply, waste management and storage, reprocessing). It presents the IFSN (the Swiss nuclear safety authority), the nuclear industry organization, and the professional bodies. Then, it describes the legal framework. It discusses the issue of nuclear plant replacement, and that of waste storage in deep geological layers, and comments the posture of the political parties on these issues. It gives a rather detailed overview of researches in the nuclear field (general framework and institutions, research reactors, researches in security and radioprotection, in nuclear safety, in controlled thermonuclear fusion, in waste management). Finally, it describes the harmonization efforts in relationship with international organizations (safety authorities and nuclear industries)

The research strategy of the Swedish Nuclear Power Inspectorate

International Nuclear Information System (INIS)

2002-06-01

In its directive to the Swedish Nuclear Power Inspectorate for 2001 and 2002, the Government asked for a report on SKI's future research strategy. This report is meant to describe future needs for SKI's regulatory and supervisory work, the need for expertise in Sweden and the possibility of international co-operation. SKI's research currently focuses on a number of strategically important areas such as reactor technology, materials and fuel issues, human factors, nuclear waste and nuclear safeguards. Over the past decade, the nuclear infrastructure has changed considerably. The nuclear power companies' previous organisations with specialist expertise and resources have been successively closed down or converted into consulting companies. Furthermore, education and research in the nuclear area at universities have been considerably reduced and expertise, resources and interest in the area have thereby decreased. A review of the availability of expertise in Sweden shows that, in many areas, resources are adequate, but that SKI, in certain cases, needs to provide focused support in order to maintain the expertise that SKI needs for its regulatory and supervisory activities. The analysis highlights two areas without any real education and research: 'Materials testing and control' and 'Management, control and organisation'. Education and research in the latter area lacks a safety perspective. SKI intends to take the initiative to conduct work within both of these areas. Since national research resources are limited, SKI has, for a long time, actively participated in international research. SKI is prioritising co-operation on research conducted in the OECD/NEA and is participating in a large number of projects organised within this framework. Since Sweden joined the EU, the importance of joint European work has increased. SKI is itself also actively participating and supporting Swedish organisations participating in European Commission projects and intends to support

Presentation of the ressac research program (rehabilitation of soils and surfaces after an accident)

International Nuclear Information System (INIS)

L'Homme, A.

1989-11-01

If, despite all the precautions taken in nuclear power plants, a severe accident was to occur in France involving extensive release of radioactive materials to the environment, existing emergency plans would be implemented enabling urgent decisions to be made with regard to the immediate protection of the population: confinement indoors, evacuation, distribution of stable iodine, etc. But, at a later stage, mean and long term actions would have to be carried out to decontaminate the polluted areas and limit subsequent contamination of the food chain, with a view to enabling the populations concerned to return to normal life. These actions would concern, in decreasing order of priority and using the WHO and IAEA definitions, the near field, closest to the accident site, and the far field, subjected to the direct impact of fallout. They should be aimed at reducing external exposure due to deposition and internal exposure by inhalation of radioactive products re-suspended in the atmosphere and by ingestion of products for human consumption. In the context of IPSN (Institute of Protection and Nuclear Safety) research and development programs on severe accidents, the RESSAC program was defined in 1985 for the purpose of studying methods and means of rehabilitating the near field and controlling problems related to the far field. Elaboration of the program is presently proceeding at the Nuclear Research Center of CADARACHE, focussed on the following main topics: assessment of what happens to the radionuclides deposited on the soil and vegetation, determination of priorities and how to intervene, management of the waste produced

The high committee for the nuclear safety transparency and information (HCTISN) is an information, consultation and debate authority devoted to the assessment of the risks linked with nuclear activities and to the analysis of their impact on public health, on the environment and on nuclear safety. Each year, the HCTISN organizes several ordinary meetings in order to analyze some specific topics of the moment, and, depending on the events, some extraordinary meetings. This document is the proceedings of an extraordinary meeting about the information and transparency in relation with the management of nuclear materials and wastes at all stages of the fuel cycle. The reason of this meeting is a request from the French Minister of ecology, energy, sustainable development and sea (MEEDDM) after the broadcast of a TV documentary entitled 'wastes: the nuclear industry nightmare' and the publication of a press article affirming that 'our nuclear wastes are hidden in Siberia'. The Minister expressed his wish to have the question of the international trade of nuclear materials examined by the HCTISN. The document is organized as follows: a first part presents the hearings of the general direction of energy and climate (DGEC), of the nuclear safety authority (ASN), of EdF, of Areva, of the CEA, of the senior official for the defense and security of the MEEDDM, of Rosatom company and of Greenpeace organisation. A second part examines the incident which took place in October 2009 at the plutonium technology workshop (ATPu) of Cadarache, where about 22 to 39 kg of plutonium powder were discovered in the gloveboxes of this facility, decommissioned in 2005 and undergoing dismantlement today. This part presents the hearings of the CEA, of AREVA, of the Institute of radiation protection and nuclear safety (IRSN), of the ASN, of the hygiene, safety and labour conditions committee (CHSCT) of Areva and CEA, and of the local information commission (CLI) of Cadarache

According to the recommendations of the International Atomic Energy Agency, Mexico is taking steps to combat illicit trafficking in nuclear material. The creation of a National Nuclear Forensic Research Laboratory (Lanafonu, acronym in Spanish) has been assigned to the Instituto Nacional de Investigaciones Nucleares (ININ, Mexico) in 2014. The objectives of this Laboratory are: to combat illicit trafficking in nuclear materials, to optimize scientific processes and techniques used to analyze nuclear materials (orphans or radioactive sources), environmental and potential biological sources as a result of the handling, transport and final storage. At present, the Lanafonu facilities are focused on the optimization of emergency and routine protocols for measuring radioisotopes in environmental and biological samples using inductive coupling mass spectrometer with magnetic sector. The main activities are: i) optimization of the methods for measuring the isotopes of Pu by alpha-spectrometry, Icp-SFMS and AMS (accelerator mass spectrometry), ii) development or radiochemical methods for routine situations and nuclear emergencies, iii) participation in the scientific technical commission on nuclear forensic science, iv) participation in international intercomparison exercises to optimize and validate methods, and v) consolidation of Lanafonu in Mexico and the IAEA.

Germany is to undertake a structured phasing-out of power generation from nuclear energy. Until the last nuclear power plant is shut down, safety must be guaranteed in line with the very latest developments in science and technology. The R and D work performed is in accord with the resolution for the structured phasing-out of the use of nuclear power. The Federal Ministry of Education and Research (BMBF) with its 'Basic Energy Research 2020+' funding concept supplements institutionally funded work of Helmholtz Institutes in a few core areas to further extend co-operation with universities. Close coordination between institutional and project funding will be ensured via the Alliance for Competence in Nuclear Technology in Germany ('Kompetenzverbund Kerntechnik'). In the area of nuclear safety and disposal research, R and D is carried out on the scientific and technological aspects of safety in existing nuclear reactors, the safety of nuclear disposal, the minimisation of highly radioactive substances ultimately requiring disposal and radiation research. Special attention is to be paid within this concept to the funding of young scientists. In addition to doctorate posts in research projects, special funding instruments are to be offered to promote the next generation of scientists. (orig.)
