    2000-01-01

    At the present time, the la Hague site strives to apply international recommendations together with national regulations concerning radiation protection, and especially the respect of limitation and optimization principles. The application of these principles is based on the implementation of a passive dosimetry and an active dosimetry. The monthly passive dosimetry is monitored by means of a photographic dosimetry film, completed with lithium fluorine thermoluminescent film badges. This personal dosimetry common to X, β, γ and neutron radiations is carried out in close relationship between the Radiation Protection Department, the Occupational Medical Department and the staff running the Plant. The application or ALARA's principle as well as that of radiation protection optimization implies to implement a complementary active dosimetry enabling to gain in real time, the personal dosimetry of each intervening person, either they be COGEMA's workers or external companies'. This active dosimetry provides with following information: This preventive dosimetry is based on the knowledge of doses integration in real time and is fitted with alarm thresholds according to the total amount of doses and dose rates. Thresholds on the dose rate are also set relatively to the radiological environment. This knowledge of doses and dose rates allows a stricter management of the works, while analyzing them according to the nature of the work, to the location and to the skills of the intervening people. This dosimetry allows to analyze and optimize doses integration according to the works nature for the whole intervening staff. The la Hague Site has developed an active personal dosimetry system, common to every intervening person, COGEMA or external companies. The DOSICARD was thus elaborated, shaped as an electronic dosimeter fitted with an alarm and a smart card. The access to controlled areas is conditioned to information given by the DOSICARD concerning medical aptitudes and

    Short lived, low and medium level waste called 'technological waste' produced by the La Hague Reprocessing Plant have been stored in the La Hague North-West concrete-lined pits until implementation at ANDRA's Centre de Stockage de la Manche (CSM). COGEMA decided to retrieve and condition 11,000 m 3 of humid solid radwaste, stored in bulk in pits. This report describes the experience gained from February 1990 to December 1998, taking into account radwaste and integrated dose rate results conditioning such waste. The procedures and means used and improved by COGEMA to comply with ANDRA's storage standards and the ever-decreasing financial costs generated by the workers, allowed to retrieve and condition 11,000 m 3 of old solid radwaste with competitive costs and in complete safety and protection of the environment.

    Short lived, low and medium level waste called 'technological waste' produced by the La Hague Reprocessing Plant have been stored in the La Hague North-West concrete-lined pits until implementation at ANDRA's Centre de Stockage de la Manche (CSM). COGEMA decided to retrieve and condition 11,000 m 3 of humid solid radwaste, stored in bulk in pits. On account of the variety of radwaste kinds, retrieving and conditioning operations represented real challenge. One goal of these operations was to ensure that the work was performed in complete safety towards environment with optimum containment and with the best radiation protection for the personnel involved. COGEMA decided to split the work into two phases. The feedback from the first phase was very helpful to the second phase. This report describes the experience gained from February 1990 to December 1998, taking into account radwaste and integrated dose rate results conditioning such waste. The procedures and means used and improved by COGEMA to comply with ANDRA's storage standards and the ever-decreasing financial costs generated by the workers, allowed to retrieve and condition 11,000 m 3 of old solid radwaste with competitive costs and in complete safety and protection of the environment.

  7. Evaluation of the long duration efficiency of the ECC storage facility of Cogema La Hague plant

    Baganz, C.; Bouland, P.; Breton, E.

    2004-01-01

    The ECC facility of Cogema La Hague has been designed in view of the storage of 24000 CSD-C type containers produced by the ACC facility. It comprises a reception and unloading unit, and a modular storage unit (alveoles). The safety of the facility is based on: a controlled ventilation (low pressurization rooms, controlled atmosphere, heat and toxic gases evacuation), a construction ensuring the static confinement, the sub-criticality and the radiological protection, and the possibility of natural ventilation of the alveoles (earthquake-dimensioned equipments). On the basis of these safety functions, the conformability of the facility with respect to long duration has been analyzed considering three aspects of the facility: the infrastructure, the waste packages and the ventilation system. In normal operation, a foreseeable service life of at least 100 years is established: simpleness and accessibility of ventilation systems, no significant corrosion of packages, durability of the reinforced concrete structure. The demonstration of a service life greater than 100 years would require the improvement of our knowledge about concretes in terms of experience feedback. The behaviour of the facility in terms of loss of technical mastery has been considered too. The scenario retained for this situation is the prolonged stoppage (several months or years) of the nuclear ventilation after a 100 years of disposal. After this period of time, both the thermal power and the hydrogen generation from waste packages will have significantly diminished, allowing a loss of technical mastery era of several years with no impact on concretes integrity. However, during long situations of non-controlled atmosphere, the corrosion behaviour of stainless steels is not predictable. (J.S.)

    Managing the operation of large commercial spent nuclear fuel reprocessing plants, such as UP3 and UP2-800 in La Hague, France, requires an extensive analytical program and the shortest possible analysis response times. COGEMA, together with its engineering subsidiary SGN, decided to build high-performance laboratories to support operations in its plants. These laboratories feature automated equipment, safe environments for operators, and short response times, all in centralized installations. Implementation of a computerized analytical data management system and a fully automated pneumatic system for the transfer of radioactive samples was a key factor contributing to the successful operation of the laboratories and plants

  9. Reliability of the fuel identification procedure used by COGEMA during cask loading for shipment to LA HAGUE

    International Nuclear Information System (INIS)

    Pretesacque, P.; Eid, M.; Zachar, M.

    1993-01-01

    This study has been carried out to demonstrate the reliability of the system of the spent fuel identification used by COGEMA and NTL prior to shipment to the reprocessing plant of La Hague. This was a prerequisite for the French competent authority to accept the 'burnup credit' assumption in the criticality assessment of spent fuel packages. The probability to load a non-irradiated and non-specified fuel assembly was considered as acceptable if our identification and irradiation status measurement procedures were used. Furthermore, the task analysis enabled us to improve the working conditions at reactor sites, the quality of the working documentation, and consequently to improve the reliability of the system. The NTL experience of transporting to La Hague, as consignor, more than 10,000 fuel assemblies since the date of implementation of our system in 1984 without any non-conformance on fuel identification, validated the formalism of this study as well as our assumptions on basic events probabilities.

    Sandu, Irina; Lac, Christine

    2003-01-01

    METEO-FRANCE is presently developing a new system named PERLE which permits real time evaluation of atmospheric dispersion at local scale. This system consists in a non-hydrostatic meteorological model at mezo-scale (Meso-NH) and a particular code for the dispersion of the chemically passive pollutants. As a result of several studies performed by DP/SERV/ENV at Meteo-France, two particular codes have been retained for the dispersion module of PERLE: DIFPAR (EDF) and SPRAY (Aria Technologies). In this study, the dispersion at local scale of Kr 85 in the area of the nuclear-wastes reprocessing plant COGEMA (La Hague) has been simulated with the two dispersion models, initialised with the meteorological fields provided by Meso-NH. The simulations concern the most complete sampling campaign of Kr 85 performed in this area on 18th and 19th september 2001. The evaluation the two models performances and of the PERLE system's results for this campaign has been done by using the CTA (Atmospherical Transfer Coefficient) measured values. (authors)

  11. ALPHA WASTE MINIMIZATION IN TERMS OF VOLUME AND RADIOACTIVITY AT COGEMA'S MELOX AND LA HAGUE PLANTS

    2003-01-01

    This paper describes the management of alpha waste that cannot be stored in surface repositories under current French regulations. The aim of the paper is to provide an overview of COGEMA's Integrated Waste Management Strategy. The topics discussed include primary waste minimization, from facility design to operating feedback; primary waste management by the plant operator, including waste characterization; waste treatment options that led to building waste treatment industrial facilities for plutonium decontamination, compaction and cement solidification; and optimization of industrial tools, which is strongly influenced by safety and financial considerations

  12. Radioecological surveillance 2001-2003 of marine environment of the dismantling workings of the old pipe of releases in sea Cogema la Hague (Anse des Moulinets)

    International Nuclear Information System (INIS)

    2005-02-01

    In order to watch the environment of the construction site of dismantling of the former pipe of releases in sea of Cogema-La Hague, the special and permanent commission of Information near the establishment Cogema of La Hague (C.S.P.I.) asked the association for the radiation monitoring in the West (A.C.R.O.) to realize a specific campaign of measures, on the basis of a protocol accepted by the C.S.P.I.. During the three years of the building work, two significant increases of the concentration in 137 Cs in the marine flora with at most, 9.3 Bq/kg dry, are noticed so be it ten times the concentration that could be measured before the building work begins. We note a net improvement of the situation after the works. The 137 Cs tends finally to disappear. For the sedimentary masses and the sands of beaches, it is outlined no increase of the contamination in 137 Cs (during the works and in posteriori) which translates in a irrefutable way contributions of the construction site. Let us remind this subject that the level of contamination of sands of the Moulinets cove by the named radionuclides is the most important of the coasts of La Hague and that a such report supposes that local events are behind. In conclusion, the campaign of measures of the ambient gamma radiation realized in August, 2004, that is three months after works, consolidates the hypothesis that the works did not generate particular radiological situation susceptible to increase the external risk of irradiation in the Moulinets cove.

    The Spent Fuel Identification for Flask Loading (SFIFL) procedure designed by COGEMA is analysed and its reliability calculated. The reliability of the procedure is defined as the probability of transporting only approved fuel elements for a given number of shipments. The procedure describes a non-coherent system. A non-coherent system is the one in which two successive failures could result in a success, from the system mission point of view. A technique that describes the system with the help of its maximal cuts (states) is used for calculations. A maximal cut contains more than one failure which can split into two cuts (sub-states). Cuts splitting will enable us to analyse, in a systematic way, non-coherent systems with independent basic components. (author)

    Due to the complexity of a spent fuel reprocessing plant and its nuclear characteristics, the operators must have real-time access to updated information on many subjects. To meet these requirements effectively, Cogema has installed a number of diversified data processing systems linked by a communications network called Haguenet. The whole system forms the La Hague Total Data Management System (TDMS) which performs a full range of functions, namely production data management, maintenance data management, technical documentation and miscellaneous. Some examples of the main process data management applications implemented within the La Hague TDMS are briefly described (nuclear materials and waste follow-up, analytical data management, operating procedures management and site inspection management). Also presented are some examples of the maintenance-related systems implemented within the La Hague TDMS (diagnostic assistance system, software maintenance center, maintenance interventions demand and spare parts data management).

    The vitrification of high-level liquid waste produced from nuclear fuel reprocessing has been carried out industrially for over 25 years by AREVA/COGEMA, with two main objectives: containment of the long lived fission products and reduction of the final volume of waste. At the 'La Hague' plant, in the 'R7' and 'T7' facilities, vitrified waste is obtained by first evaporating and calcining the nitric acid feed solution-containing fission products in calciners. The product-named calcinate- is then fed together with glass frit into induction-heated metallic melters to produce the so-called R7/T7 glass, well known for its excellent containment properties. Both facilities are equipped with three processing lines. In the near future the increase of the fuel burn-up will influence the amount of fission product solutions to be processed at R7/T7. As a consequence, in order to prepare these changes, it is necessary to feed the calciner at higher flow-rates. Consistent and medium-term R and D programs led by CEA (French Atomic Energy Commission, the AREVA/COGEMA's R and D and R and T provider), AREVA/COGEMA (Industrial Operator) and AREVA/SGN (AREVA/COGEMA's Engineering), and associated to the industrial feed back of AREVA/COGEMA operations, have allowed continuous improvement of the process since 1998: - The efficiency and limitation of the equipment have been studied and solutions for technological improvements have been proposed whenever necessary, - The increase of the feeding flow-rate has been implemented on the improved CEA test rig (so called PEV, Evolutional Prototype of Vitrification) and adapted by AREVA/SGN for the La Hague plant using their modeling studies; the results obtained during this test confirmed the technological and industrial feasibility of the improvements achieved, - After all necessary improved equipments have been implemented in R7/T7 facilities, and a specific campaign has been performed on the R7 facility by AREVA/COGEMA.

  8. Epidemiological study around La Hague

    1999-01-01

    The North Cotentin is in France, the area where have been led until now, the biggest number of epidemiology studies on the effects of ionizing radiations on man, in order to assess the leukemia incidences and other cancer pathologies around nuclear facilities. The North Cotentin concentrates four nuclear installations.The objective of this file is to take stock of the situation in this field. In 1995 and 1998 have been published two sections of an epidemiology study about the incidence of leukemia in North Cotentin (J.F. Viel study for the period 1978-1992, Spira study for 1993-1997). The study of the Professor Spira does not bring to the fore a significant excess of leukemia for the period 1978-1997. The report of the professor Spira advocates several complementary epidemiology studies to precise or complete the data and lighten the causes of leukemia in North Cotentin. The studies of J.F.Viel shows that it does not exist a significant excess of cases in the studied area (25 cases for 22.8 expected cases, so a non significant difference) but notices an aggregate at the limit to be significant in the Beaumont-Hague canton (4 cases for 1.4 expected cases). J.F.Viel puts forward a relationship between the risk increase (of leukemia incidence) and some individual characteristics linked to the way of life of the studied persons: the North Cotentin beaches frequenting by the mothers or the children at least one time by month, the consumption of fish or shellfish having a local origin at least one time by week. This study suggests that it is the radioactivity, on the beaches on in fishes and shellfish that would be at the origin of the additional noticed leukemia. The authorities asked at the beginning of 1997, a scientific commission directed by the Professor Souleau to propose a new epidemiology study on the leukemia risk around La Hague. The report concludes that the leukemia incidence in the North Cotentin is in accordance with the expected incidence (25 observed

    1993-01-01

    After a brief recall of the different aspects of the commercial irradiated fuel reprocessing, this paper presents the achievements of the recently commissioned UP3 plant at La Hague. The advanced Purex process implemented with a total waste management results in important waste volume minimization, so that the total volume of high-level and transuranic waste is lower than what it would be in a once-through cycle. Moreover, further minimization is still possible, based on an improved waste management. Cogema has launched the necessary program, which will lead to an overall volume of HLW and TRU wastes of less than 1 m 3 /t by the end of the decade, the maximum possible activity being concentrated in the glass

  10. Reprocessing RTR fuel in the La Hague plants

    Starting in 2006, research reactors operators will be fully responsible for the back-end management of their spent fuel. It appears that the only solution for this management is treatment-conditioning, which could be done at the La Hague reprocessing complex in France. The fissile material can be separated in the reprocessing plants and the final waste can be encapsulated in a matrix adapted to its potential hazards. RTR reprocessing at La Hague would require some modifications, since the plant had been primarily designed to reprocess fuel from light water reactors. Many provisions have been taken at the plant design stage, however, and the modifications would be feasible even during active operations, as was done from 1993 to 1995 when a new liquid waste management was implemented, and when one of the two vitrification facilities was improved. To achieve RTR back-end management, COGEMA and its partners are also conducting R and D to define a new generation of LEU fuel with performance characteristics approximating those of HEU fuel. This new-generation fuel would be easier to reprocess. (author)

    CEA's 100%-owned subsidiary Cogema was set up in July 1966. 1979 was satisfactory and 1980 looks promising. Cogema is involved in all the phases of the nuclear fuel cycle except for the manufacture of the fuel itself, a gap that it is planning to fill. Cogema's discovery of the Coutras deposit in the Gironde is 'the good news' of the year. Work on the Eurodif uranium enrichment plant at Tricastin is almost finished and by the end of 1981 it will be operating at its full capacity of 10,8 million SWU. On the processing side, work on expanding existing facilities has begun (UP2 800 and UP3). In 1985 La Hague's foreign clients UP2 will process 1,200 tons and UP3 6000 tons [fr

    The risks associated to the operation of a reprocessing plant come from the important quantities of radioactive matter. To insure the reprocessing safety consists in keeping, in any circumstance, the containment of radioactive matter. That this objective that leads the safety at any step of the factory life. Three risks families are listed: the risks from nuclear origin, associated to the specific physico-chemical behaviours of radioactive matter (dispersion and criticality, thermal risks and risks bound to the hydrogen production); the second family is the group of internal risks resulting from the industrial activity (chemical risks, fire risks, dysfunctions of electric installations or falls of loads); the last family is the group of external risks resulting from the impact of events reaching the site where are established the installations (risks associated to climatic conditions, risks associated to surrounding activities such explosions, fires, impact resulting from the fall of a tourism plane or road transport of hazardous matter).

    1989-01-01

    The Cogema plant at La Hague is the world's leading nuclear fuel reprocessing plant. A major extension program was initiated in 1980. It includes the construction of a new 800 t/year capacity plant (UP3), to be commissioned in 1989, and the doubling of the capacity of the present plant (UP2 800) scheduled to go on stream in 1992. On the occasion of this huge capital investment, an overall assessment was made of the operating and maintenance systems of the site. The general objective was to achieve maximum productivity and availability, in view of: - the extreme importance of safety for the protection of workers and the environment, - the high level of automation required by the complexity of the process, - the inaccessibility of the nuclear equipment, the scale of the investment. To achieve this goal, a set of diagnostic and maintenance aid systems were developed and installed. A general site data network serves to link these systems and to distribute the corresponding data to the different users. This paper describes these different systems, presents the functionalities of the network and demonstrates the sequencing of the operations in a typical maintenance application

    New radioecological observations have been made in the environment of the La Hague (North-West Cotentin) spent fuel processing plant to supplement earlier studies on the transfer of sea-borne radioactive wastes and on radioactivity levels found in the North-West sector of the Cotentin and some distance away on the channel coasts. Of the radionuclides discharged by the plant, ruthenium-106 and cerium-144 account for most of the artificial γ activity found in living species and sediments. Together with plutonium they tend to disperse less than a radionuclide present in essentially soluble form such as cesium-137. Certain coastal deposits moreover tend to be more pronounced South-West than East-South-East of the discharge point. Finally the radioactivity levels observed and their repercussions on public health show good agreement with the results of the previsional study carried out before the plant was started up [fr

    Starting 2 November 1999, COGEMA launched a mass public communication campaign and creating an Internet site, equipped with cameras (web-cams), to make everyone familiar with the COGEMA plant at La Hague. This system is designed to serve a communication policy that is resolutely open and attentive to French public concerns: - The COGEMA plant at La Hague is often perceived as a mystery, occult and dehumanized world. This communication campaign, entitled 'We have nothing to hide', illustrated COGEMA's determination to inform the citizens in the greatest possible transparence and its wish to bring the Group's industrial operations and the persons working there closer to the public. The campaign included TV commercials and press ads. The underlying principle is to work on issues that have made news. The televised system included two films, shot at La Hague. The first, lasting 90 seconds, consists of interviews and testimonies of employees who represent the professional and human diversity of the plant. The second, in 45-second format, presents the questions to which public opinion wants answers. These questions are also repeated in the press ads. - To ensure that everyone obtains all the answers to his questions, the TV spots and press ads refer to the website http://www.cogemalahague.fr and to a toll-free number 0 800-64-64-64 . This campaign was the first stage of a long-term approach. Its positive reception from the public strengthens COGEMA's resolution to anticipate the legitimate information's needs expressed by the public opinion. As a responsible firm, COGEMA means to adapt her communication policy in order to make the whole activities of the Group widely known. Beyond communication, COGEMA intends to carry on showing her attachment to nuclear industry and bolstering this sector's interests on the international scene. (authors)

    Through its subsidiary COGEMA, the CEA Group is engaged in building a very large industrial complex, designed to raise French capacity for reprocessing LWR fuels to 1600 t/year. This refers to the UP3 and UP2-800 plants currently being built at La Hague. Naturally, the well-knoxn ''Purex'' process is employed in its main features, since it has proved entirely satisfactory in the UP2 facilities. Scaling up, essentially applied to capacity and aiming at a factor of 4, nevertheless requires a thorough re-assessment of all the steps in the process. Main research topics include components for bulk chopping of the fuel bundle (blades, roller, rails, ventilation, anticorrosion barriers) dissolution, liquid-liquid extraction solvent recycling, PuO 2 redissolution, liquid and solid waste treatment

    Two reprocessing plants are operated by Cogema: Marcoule (since 1958) and La Hague (since 1967). Since 1976 the latter has been reprocessing LWR assemblies in its 'HAO' workshop, operation of which has provided industrial experience in the reprocessing of this type of fuel. This experience will be drawn upon in the construction of extensions to the La Hague plant, namely the UP3 plant, which will have a capacity of 800 t/a, and UP2-800, which will expand the present plant likewise to a capacity of 800 t/a. These extensions will contain a number of improvements, particularly in the areas of safety and waste treatment, and of procedure and equipment. A considerable R and D contribution is provided by the French Atomic Energy Commission (CEA), which is the licence holder, with its laboratories at Fontenay and the pilot workshop and industrial prototypes service at Marcoule. This activity supports all phases of the project, from the establishment of basic principles to the definition of essential characteristics of equipment, covering also the testing of full-scale prototypes (mock-ups) for the principal components: rotating continuous dissolver, swinging decanter, subcritical pulsed columns, used-solvent distilling apparatus, fission-product vitrification furnace, etc. Engineering work for the new facilities is performed by the Societe generale pour les techniques nouvelles in four phases: (1) establishment of basic data; (2) preparation of preliminary plans (including an estimate and a preliminary schedule) and of the preliminary safety reports; (3) drafting of the 'project' file, giving definitive costs and deadlines; (4) implementation, up to and including the operational testing stage. All phases of design and implementation are subject to a quality assurance programme. Extension of the La Hague plant represents an investment of 23,500 million French francs (in July 1981). Construction is expected to be completed in 1989. (author)

    The U.P.2 plant, built at La Hague Center is intended mainly for the reprocessing of spent fuels coming from (as metal) graphite-gas reactors and (as oxide) light-water, heavy-water and breeder reactors. In each of the five large nuclear units the digital processing of measurements was dealt with until 1974 by CAE 3030 data processors. During the period 1974-1975 a modern industrial computer system was set up. This system, equipped with T 2000/20 material from the Telemecanique company, consists of five measurement acquisition devices (for a total of 1500 lines processed) and two central processing units (CPU). The connection of these two PCU (Hardware and Software) enables an automatic connection of the system either on the first CPU or on the second one. The system covers, at present, data processing, threshold monitoring, alarm systems, display devices, periodical listing, and specific calculations concerning the process (balances etc), and at a later stage, an automatic control of certain units of the Process [fr

    Operation of the UP2 and UP3 reprocessing plants at La Hague, France, generates considerable data processing requirements. To meet these requirements, a Total Data Management System (TDMS) has been designed and installed to operate the biggest Ethernet industrial network in Europe. This network, called Haguenet, interconnects a large number of computers and user terminals. The TDMS' main operational functions are plant operation and production data management, maintenance data management, technical documents management and computer-aided design (CAD). Extensive experience was gained through the design and operation of the TDMS at La Hague. (author)

    Four-year investigations of the coastal surface sediments and associated radionuclides in the English Channel show complex distribution patterns around La Hague. Plutonium ratios in the particulate fraction confirm the general understanding gathered from long-term gamma studies - mainly that accumulation of La Hague generated radionuclides is in the Bay of Mont-Saint-Michel and along the Normandy-Brittany Coast. The oil from the Amoco Cadiz accident caused a significant increase in coastal sediment activity of 144 Ce. Experimental studies with plutonium and hydrocarbons indicate that plutonium is more difficult to desorb than 144 Ce. (author)

    For the last seven years, AREVA/COGEMA has been implementing the second phase of its burn-up credit program (the incorporation of fission products). Since the early nineties, major actinides have been taken into account in criticality analyses first for reprocessing applications, then for transport and storage of fuel assemblies Next year (2004) COGEMA will take into account the six main fission products (Rh103, Cs133, Nd143, Sm149, Sm152 and Gd155) that make up 50% of the anti-reactivity of all fission products. The experimental program will soon be finished. The new burn-up credit methodology is in progress. After a brief overview of BUC R and D program and COGEMA's application of the BUC, this paper will focus on the new burn-up measurement for UO2 and MOX fuel assemblies.

First, they present the AREVA NC plant and evoke the legal context concerning the waste management. They report and discuss the analysis of the presence and behaviour of tritium in irradiated fuel, of its behaviour during spent fuel processing, the evolution of tritium releases (legal limitations, evolutions since 1992), of measurement of activity in effluents, and discuss a study of possible reductions of tritium releases by La Hague plants (mainly in sea waters). They also report the computational assessment of the dosimetric impact of tritium on neighbouring population. They describe how the presence of tritium in the environment is monitored within the annual radioactivity monitoring programme

    Permits for low level radioactive liquid waste releases by the LA HAGUE (Cotentin, France) fuel reprocessing plant are based on an accurate radioecological study of the marine environment. Since 1967, the monitoring of indicators such as seawater, sediments and marine organisms (Fucus serratus, Laminaria sp., Mytilus sp., ...) have made it possible to create an important environmental data base. A statistical treatment has been used to quantify the spatio-temporal (daily, seasonal, local and regional) variabilities of these indicators from 1975 up to now. It has demonstrated the interest of F. serratus seaweed as bioindicators of radioactivity. Moreover it appears that seawater-soluble radionuclides such as 125 Sb and 137 Cs are monitored through longer distance from the outlet than those bound to particles such as 144 Ce. A study of the sestonic load by satellite images suggested a number of geographical sites of potential accumulation through particle transport, some of which were verified by radioactivity measurements of sediments. However, such accumulation was not confirmed by the particle size distribution at the level of the Cap de LA HAGUE associated with radioactive measurements of seawater. A spectral analysis of biota radioactive levels vs radioactive waste releases showed a time delay of 2 - 4 months for F. serratus and Mytilus sp. collected in the local area of LA HAGUE after either an increase or a decrease of the releases. Modeling of marine currents fields associated with a transfer model can now be used to predict, at small time scales, the radioactivity levels inthe various Cotentin marine compartments from the liquid waste releases [fr

    The principal aim of this report is to assist the Committee of Petitions of the European Parliament in its consideration of Petition 393/95 brought by Dr. W. Nachtwey. The Petition expresses concerns about radioactive discharges from nuclear reprocessing plants at Sellafield in the UK and La Hague in France, and their possible adverse health effects. Six years after the Petition was introduced, the Petitioner main concerns remain relevant. This report concludes that reprocessing discharges are a valid matter for the Committee consideration. It also concludes that, on balance, the Petitioner's concerns over radioactive discharges from Sellafield and La Hague are justified. The report presents evidence and data on: 1) radioactive discharges from the Sellafield and La Hague sites; 2) resulting nuclide concentrations in environmental media including foodstuffs; 3) radiation doses from nuclide discharges to critical groups near the sites; 4) adverse health effects near the two sites; and 5) resulting collective doses from nuclide discharges. The report also examines a number of current issues in radiobiology concerning health effects from exposure to ionising radiation, in particular genetic and in utero effects. In addition, in accordance with contract specifications, the report examines other major factors that might influence future decision-making on reprocessing. It provides information on the legal framework, the operational history of the plants and the economic case for reprocessing compared with available alternatives for spent nuclear fuel management. The report also makes policy-related recommendations that take into account current knowledge and uncertainties in risk assessment and the availability of alternatives to reprocessing in spent fuel management.

    In this book, the author denounces the collusion between the French government and the nuclear lobby and the dark side of the implementation of the nuclear program in France without any real democratic debate with the citizens. The history of the La Hague radioactive waste facility is taken as an example. The author recommends the development of alternative and decentralized energy sources. He considers also that the main questions generated by the nuclear industry (radioactive wastes, spent fuels reprocessing, health hazards, environmental impact, terror threat..) are still unanswered since 30 years.

    The use of zirconium was developed to solve some problems of severe corrosion in boiling nitric medium, and to guarantee the service life of the equipment concerned. The paper presents the experience gained since the early 1970s, when the first units made of zirconium were used in French reprocessing plants. For the new La Hague UP3 and UP2 800 plants, it was decided to extend the use of zirconium to make large-scale equipment and, to do so, a major R and D program was implemented, of which the main results are presented

    The Particular intervention plan (PPI in French) is an emergency plan which foresees the measures and means to be implemented to address the potential risks of the presence and operation of a nuclear facility. This plan is implemented and developed by the Prefect in case of nuclear accident (or incident leading to a potential accident), the impact of which extending beyond the facility perimeter. It represents a special section of the organisation plan for civil protection response (ORSEC plan). The PPI foresees the necessary measures and means for crisis management during the first hours following the accident and is triggered by the Department Prefect according to the information provided by the facility operator. Its aim is to protect the populations leaving within 10 km of the facility against a potential radiological hazard. The PPI describes: the facility, the intervention area, the protection measures for the population, the conditions of emergency plan triggering, the crisis organisation, the action forms of the different services, and the post-accident stage. This document is the public version of the Particular intervention plan of the Areva NC La Hague fuel reprocessing plant (located on the territories of Beaumont-Hague, Digulleville, Herqueville, Jobourg and Omonville-la-Petite towns, Manche, France) which comprises the totally decommissioned UP2 400 unit, and the UP2 800 production unit still in operation

  5. MTR spent fuel back-end - Cogema's long-term commitment

    1998-01-01

    MTR spent fuel back end has been subject to many reversal and uncertainties in the past 10 years. Until the end of 1988, US obligated materials were subject to the Off site Fuels Policy (OFP). Under this policy, spent fuels were returned to USA, and were reprocessed there. This OFP took end the 31th of December 1988, and Research Reactor's operators had to implement others solutions: On site storage or Reprocessing in Europe. Meanwhile the RERTR Program was leading to a new LEU fuel to replace HEU aluminide. This new silicide fuel has one main drawback: it cannot be reprocessed in working plants without some process main line modifications. Fortunately, a new Research Reactors spent fuels return policy has been set up by the US in the early 1996. This new policy applies to all reactors converted or that have agreed to convert to LEU, and reactors operating with HEU for which no suitable LEU is available. It covers all the spent fuels discharged until 2006/05/12. But after that period of time, each reactor will be fully responsible for its spent fuels. Since the end of 1996, COGEMA is proposing reprocessing services for Aluminides spent fuels, based on the La Hague capability. This COGEMA answer is for the long term, as the La Hague plant has a good load for the coming years, including the first decade of the next century. Further, this activity benefits from a strong R and D support, that allowed fulfilling the evolutive needs of our customers, and gives us the ability to adapt the plant to the future market. Taking advantage of this flexibility, COGEMA offers Research Reactors' operators a long-term commitment. Already two reactors' operators have chosen to contract with COGEMA for the whole life of their reactors. The contracts execution is under progress and the first transportation will take place soon. Beside today's services, COGEMA is involved in R and D activities to support new fuels development enhancing present LEU performances and having the ability to

    Awaiting for a decision about radioactive waste repository, the spent fuel elements are stored in the storage pools at the La Hague facility. The water in the pools is permanently cooled and purified to maintain the temperature, radioactivity and chemical pollution under preset limits. The first safety problem is concerned with the spent fuel transport casks. Opening of the casks is done under water in a number of facilities. The most recent approach is done by the company To, which established dry manipulation which enables to minimise the risk of possible cask failures as well as external contamination of cooling fins of the casks. Another general safety related problem is related to criticality risk caused by possible cooling failures or by external events like earthquakes. Special probability limit is set up for seismic events to be less than 10 -7 /year. Equally, risk of fuel assembly failures due to possible chocs and possibility of defects in pool isolation are taken into account [fr

    COGEMA research expenses represent about Euro 100 million per year. They include the expenses for internal and external research programs and research management as well as the expenses for pre-engineering studies leading to cost evaluation. They are divided between front-end, back-end and nuclear services. Front-end expenses fell sharply when research on the SILVA enrichment process was dropped. The main objectives of the research are to maintain the ability of the industrial tool to satisfy COGEMA's clients and to increase operational safety while reducing the impact on the environment. It is also to eliminate the legacy of previous operations and to prepare for future evolutions. As far as the back-end is concerned, a large part of expenses is devoted to the 'Program of Common Interest' (PIC) with the CEA. Thanks to this fruitful collaboration, outstanding results have been obtained in the building, start-up and operation of the two modern reprocessing plants in La Hague. A new agreement is about to be signed with the CEA to follow on from the first one signed in 1978. According to this agreement, COGEMA will be financing as a lump sum a part of the expenses of ATALANTE, which is considered a very valuable research tool. Today, the main program in the PIC is still support to the La Hague reprocessing plant. More specifically, some work is still needed in the Puretex program to further improve the present performance of the plants and adapt them to the burn-up increase. There are significant programs on innovative waste vitrification, historical waste retrieval and conditioning and waste characterization including long-term behavior. Concerning Partition and Transmutation, COGEMA support is limited to the former. There is a strong incentive to understand and prepare evolutions to come that can contribute to sustainable development. Such advanced programs are also under consideration in other countries, which were not up to now willing to reprocess, such as the US

  11. Facility - transportation system interface at COGEMA (experience in taking delivery of spent fuel)

    COGEMA has long experience in taking delivery of spent fuel from LWR's. This activity is now fully industrialized. Great care is taken by COGEMA and their affiliates in this business, generally beyond the normal regulatory limits, and this is quite normal, COGEMA wanting to prevent, by all possible means, causes of incidents or accidents which could destroy the position it has established and the confidence placed in it by many customers. It is clear that the situation is quite different at reactors and at reprocessing plants; the limited number of flasks handled at reactors (in general five per year) is generally not enough to lead reactor operators to invest in sophisticated equipment and to adopt procedures allowing extremely small exposures of their personnel, while the great number of flasks received each year in a plant like La Hague (not fewer than 200 per year) justifies the investment in more specialized equipment (automation, remote operation, more sophisticated tools, etc.) and allows the personnel to be very well trained to that particular type of work. These are factors leading to very limited exposures of the personnel although the work performed in a repocessing plant is generally more complex (deeper decontamination, closer work, maintenance, etc.) than in a reactor

    The AD2 workshop of the new spent nuclear fuel reprocessing plant at La Hague in France will process and package dry solid wastes. The waste packages will be segregated according to their activity levels and stored at temporary on-site facilities. Full commissioning is scheduled for end-1988. However, operation of the TO dry spent field unloading and receiving unit at La Hague required early availability of some waste processing functions and part of the AD2 workshop was commissioned towards the end of 1986. The new La Hague plant is organized into four main zones: - zone 1 is an uncontrolled area with no permanent contamination and zero risk of accidental contamination, - zone 2 is a controlled are with no permanent contamination and low risk of accidental minor contamination, - zone 3 is a controlled area with no permanent contamination but a risk of minor contamination due to various incidents, - zone 4 is a controlled area with permanent contamination. The AD2 workshop will handle all dry solid wastes from zones 2, 3 and 4. It will also: characterize the resulting waste packages (contents, mass, alpha, beta and gamma activity, dose equivalent rate) and check for absence of surface contamination; transfer the packages to temporary on-site storage facilities; store and administer mobile handling tasks and transporters

    Although many used nuclear fuel types have already been recycled, recycling plants are generally optimized for Light Water Reactor (LWR) UO{sub x} fuel. Benefits of used fuel recycling are consequently restricted to those fuels, with only limited capacity for the others like LWR MOX, Fast Reactor (FR) MOX or Research and Test Reactor (RTR) fuel. In order to recycle diverse fuel types, an innovative and polyvalent shearing and dissolving cell is planned to be put in operation in about 10 years at AREVA's La Hague recycling plant. This installation, called TCP (French acronym for polyvalent fuel treatment) will benefit from AREVA's industrial feedback, while taking part in the next steps towards a fast reactor fuel cycle development using innovative treatment solutions. Feasibility studies and R/Development trials on dissolution and shearing are currently ongoing. This new installation will allow AREVA to propose new services to its customers, in particular in term of MOX fuel, Research Test Reactors fuel and Fast Reactor fuel treatment. (authors)

    In 2009 and 2010, the Institute for Nuclear Safety and Radiation Protection (IRSN) lead a pilot action dealing with the decommissioning of a workshop located on the site of Areva's La Hague fuel-reprocessing plant site in Northwestern France. The purpose of the pilot program was to test ways for IRSN and a few local stakeholders (Non-Governmental Organizations (NGOs) members, local elected officials, etc.) to engage in technical discussions. The discussions were intended to enable the local stakeholders to review the operator's decommissioning application and provide input. The pilot program confirmed there is a definite challenge in successfully opening a meaningful dialogue to discuss technical issues. Three factors influence the extent of the challenge: the knowledge gap between experts and local stakeholders, the conflict between transparency and confidentiality which is inherent with technical topics, and the difficulty for an official expertise institute to hold a dialogue with 'outsiders' during an ongoing reviewing process in which it is participating. The pilot program, given its mixed results, also provided valuable lessons for further improvement of stakeholders' involvement. (authors)

    In-air tritium measurements were conducted around the AREVA NC La Hague reprocessing plant, as well as on other sites that are not impacted by the nuclear industry in northwest of France. The results indicate that the dominant tritium form around the AREVA site is HT (86%). HT and HTO levels are lower than 5 and 1 Bq. m -3 for hourly samples taken in the plume. No tritiated organic molecules (TOM) were detected. 26 measurement campaigns were performed and links were established between near-field 85 Kr, HT and HTO activities. Environmental measurements are in line with those taken at the discharge stack, and tend to demonstrate that there are no rapid changes in the tritium forms released. Out of the influence of any nuclear activities, the levels measured were below 13 mBq.m -3 for HT and 5 mBq.m -3 for HTO (<0.5 Bq. L -1 ). HTO level in air seems to be influenced by HTO activities in surrounding seawater. Copyright © 2017 Elsevier Ltd. All rights reserved.

  17. Complementary safety assessment assessment of nuclear facilities - La Hague plant - AREVA

    International Nuclear Information System (INIS)

    2011-01-01

    This complementary safety assessment analyses the robustness of La Hague plant to extreme situations such as those that led to the Fukushima accident. Robustness is the ability for the plant to withstand events beyond which the plant was designed. Robustness is linked to safety margins but also to the situations leading to a sudden deterioration of the accident sequence. Moreover, safety is not only a matter of design or engineered systems but also a matter of organizing: task organization (including subcontracting) as well as the setting of emergency plans or the inventory of nuclear materials are taken into consideration in this assessment. This report is divided into 10 main chapters: 1) the feedback experience of the Fukushima accident; 2) description of the site; 3) featuring the activities and installations; 4) accidental sequences 5) protection from the earthquake; 6) protection from the flood; 7) protection from other extreme natural disasters; 8) the loss of electrical power and of the heat sink; 9) the management of severe accidents; and 10) subcontracting policy. This study shows a globally good robustness of the plant for the considered risks and, in the case of a severe accident, specified remedial actions can be brought into play by the staff to secure the installations.

    This article highlights four major acquisition by Cogema as it attempts to become the world's only fully integrated supplies of nuclear fuel. April 1992, Cogema buys 70% of German mining and trading company Urangesellschaft, significantly increasing its uranium reserves in the so-called open-quotes dollar-zoneclose quotes of the US, Canada, and Australia, as well as in Namibia and Niger. The UG deal solidifies Cogema's stature as a top-rank uranium producer and gives it a large presence in uranium trading. July 1992, As part of the consolidation of the French nuclear industry, Cogema buys the front-end fuel cycle and transportation businesses of Pechiney. February 1993, Cogema buys Cameco's 20% share of the Cluff Lake mine in Saskatchewan, giving it full ownership of one of the world's leading uranium deposits, with ore grades around 1% U3O8. May 1993, in its biggest deal yet, Cogema buys all the uranium assets of the French oil group Total. The deal leaves Cogema as France's only uranium producer

    1998-01-01

    Industrial reprocessing at La Hague was started in 1966. During 30 years. the annual rate of production gradually increased, up to more than 1,600 tons. Simultaneously, considerable innovative design and technology was introduced at all steps of the process, including effluent treatment and waste management. The characteristics of reprocessed fuel elements also changed. from low burn-up metallic fuel to high burn-up oxides. Reflecting all those evolutions, the plant discharges to the atmosphere and to the sea have shown significant variations in quantity and in composition. The complete history of liquid and gaseous releases displays a broad spectrum of situations, as to the relative weight of each radionuclide. However, the level of discharge has always remained significantly lower than the authorized limits. whatever radionuclide. Moreover, discharges to the sea have continuously decreased for 10 years, in spite of fast rising rate of production. As to the total radiological impact of discharges. it was permanently maintained well within the acceptable level of 0.15 mSv/year for the reference groups of neighbouring population, as decided for the level of authorizations. Since 1988, several actions have been decided in order to minimize the present and future impacts: improved liquid effluent treatment, extended recycling of liquid effluents towards vitrification, supplementary filtration of gaseous effluents for iodine scavenging. As a result, the plant will be able to maintain the overall impact from all discharges at less than the present acceptable level, in spite of projected wider domain of operations: - modified grades of reprocessed fuel, - decommissioning operations; - treatment of older waste stocks.

    Since the beginning of industrial nuclear plants like recycling, mechanical master-slave manipulators have been widely used for operation and maintenance in hot cells, in conjunction with shielding windows. In the La Hague plant for instance, all hot cells where maintenance is or could be required are fitted with shielding windows and through-wall telescopic master-slave manipulators. This well mastered solution, if used by highly skilled workers, has demonstrated its capability to perform all the maintenance tasks required, as long as equipment and tools inside the cell were designed accordingly. However, this technology has also shown significant limitations in terms of capacity, flexibility, efficiency and reliability. In order to improve those characteristics, AREVA and CEA have developed together a new technology: computer-aided master-slave manipulators. By replacing the traditional mechanical link, between the 'slave arm' in the cell and the 'master arm', with motors, sensors and electronics, this new tool improves load capacity and provides added flexibility and efficiency, while protecting the slave arm from overload and therefore improving reliability. In addition, this new device was developed to be fully compatible with current La Hague configuration. After developing and testing this solution in realistic but inactive environment, by performing all kinds of operation and maintenance activities with trained workers, the first generation tool was improved by incorporating feed-back and suggestions from operators. Second generation system was then developed, and first introduced in 2010 in an active cell of the La Hague plant, namely a vitrification cell. After a few months in operation, feedback from manufacturing staff was so positive that implementation of several new arms was decided for 2011. This paper will describe how this development benefited from the existing know-how and component library jointly developed by AREVA and CEA, as well as the main

  1. Four years of experience with the use of calculated isotopic correlations in establishing input balances at the La Hague plant

    For more than four years the La Hague reprocessing plant has been using calculated isotopic correlations to establish and check its input balances. The masses of uranium and plutonium entering the plant are determined by the gravimetric balance method, which utilizes the burnup obtained by calculated isotopic correlation as well as the Pu/U ratio measured at the dissolver after cross-checking with the values obtained by correlation. Further, a verification of all the parameters needed to establish these balances - whether physical or chemical in origin - is carried out systematically by means of internal coherence constants which make it possible to detect any anomalies in the dissolution data. The calculated isotopic correlations were evaluated when the analyses of numerous representative samples of irradiated fuel and experimental results of separated isotopic irradiation in water reactor spectra had been interpreted. The accuracy achieved was improved by allowing in the neutron calculations for effects inherent in the first reactor core and by selecting a set of calculation functions which attenuates (by compensation effects) the various perturbations in the irradiation history. The results obtained at La Hague with calculated isotopic correlations on nearly 600 t of reprocessed UO 2 , because of their large number and above all their high quality, suggest that it be proposed extending the method to other reprocessing plants. This could be done by the operator himself or by national or international control bodies within the framework of a safeguards arrangement. (author)

    The performance of the vitrification process currently used in the La Hague commercial reprocessing plants has been continuously improved during more than ten years of operation. In parallel COGEMA (industrial Operator), the French Atomic Energy Commission (CEA) and SGN (respectively COGEMA's R and D provider and Engineering) have developed the cold crucible melter vitrification technology to obtain greater operating flexibility, increased plant availability and further reduction of secondary waste generated during operations. The cold crucible is a compact water-cooled melter in which the radioactive waste and the glass additives are melted by direct high frequency induction. The cooling of the melter produces a solidified glass layer that protects the melter's inner wall from corrosion. Because the heat is transferred directly to the melt, high operating temperatures can be achieved with no impact on the melter itself. COGEMA plans to implement the cold crucible technology to vitrify high level liquid waste from reprocessed spent U-Mo-Sn-Al fuel (used in gas cooled reactor). The cold crucible was selected for the vitrification of this particularly hard-to-process waste stream because it could not be reasonably processed in the standard hot induction melters currently used at the La Hague vitrification facilities : the waste has a high molybdenum content which makes it very corrosive and also requires a special high temperature glass formulation to obtain sufficiently high waste loading factors (12% in molybdenum). A special glass formulation has been developed by the CEA and has been qualified through lab and pilot testing to meet standard waste acceptance criteria for final disposal of the U-Mo waste. The process and the associated technologies have been also being qualified on a full-scale prototype at the CEA pilot facility in Marcoule.

    The performance of the vitrification process currently used in the La Hague commercial reprocessing plants has been continuously improved during more than ten years of operation. In parallel COGEMA (industrial Operator), the French Atomic Energy Commission (CEA) and SGN (respectively COGEMA's R and D provider and Engineering) have developed the cold crucible melter vitrification technology to obtain greater operating flexibility, increased plant availability and further reduction of secondary waste generated during operations. The cold crucible is a compact water-cooled melter in which the radioactive waste and the glass additives are melted by direct high frequency induction. The cooling of the melter produces a solidified glass layer that protects the melter's inner wall from corrosion. Because the heat is transferred directly to the melt, high operating temperatures can be achieved with no impact on the melter itself. COGEMA plans to implement the cold crucible technology to vitrify high level liquid waste from reprocessed spent U-Mo-Sn-Al fuel (used in gas cooled reactor). The cold crucible was selected for the vitrification of this particularly hard-to-process waste stream because it could not be reasonably processed in the standard hot induction melters currently used at the La Hague vitrification facilities : the waste has a high molybdenum content which makes it very corrosive and also requires a special high temperature glass formulation to obtain sufficiently high waste loading factors (12 % in molybdenum).

    The aim of this work was to study the near-field dispersion of (85)Kr around the nuclear fuel reprocessing plant at La Hague (AREVA NC La Hague - France) under stable meteorological conditions. Twenty-two (85)Kr night-time experimental campaigns were carried out at distances of up to 4 km from the release source. Although the operational Gaussian models predict for these meteorological conditions a distance to plume touchdown of several kilometers, we almost systematically observed a marked ground signal at distances of 0.5-4 km. The calculated atmospheric transfer coefficients (ATC) show values (1) higher than those observed under neutral conditions, (2) much higher than those proposed by the operational models, and (3) higher than those used in the impact assessments.

    Wastes have been temporarily stored in dedicated silos in La Hague reprocessing plant. These wastes are to be retrieved in the near future and to be conditioned for final disposal. Some of these wastes are supposed to be encapsulated in cement matrix and, depending on the chemical composition of the waste streams, several projects are presently ongoing. The present article aims to focus on one amongst these cement encapsulation relevant projects, namely the conditioning of a mix of spent ion-exchange resins (from filtration of pool) and fine particles (insoluble fission products from spent fuel dissolution and Zircaloy and stainless steel fines from cladding shearing). The project, aims to retrieve these wastes from a silo, separate the resins and fine particles from the other waste (hulls and end pieces), in order to encapsulate the intermediate-level fines and resins in a cement matrix. The waste forms will be produced in AREVA's La Hague reprocessing plant, prior to being sent as intermediate-level waste to a long-term repository. The cement formulation developments were initially carried out at a small scale at C.E.A. Marcoule on surrogate wastes. One of the main issues that were considered was the chemical compatibility between waste and cement matrix. Indeed, swelling phenomena are sometimes reported when ion exchange resins are embedded in cement matrixes such as Portland cement. This kind of destructive phenomenon has been prevented by the use of cement containing a high amount of ground granulated blast furnace slag. The impact of the variability of ionic charge of the resins on the waste form's properties has also been addressed in order to comfort the results obtained on the reference ionic charge of resins NaNO 3 . Once the results obtained were satisfactory, intermediate scale and full scale tests were performed by AREVA. These tests have focused on adjusting the mixing process and controlling the thermal properties of the mix during setting

    The partnership between the Cogema group and Japan in the domain of fuel cycle started about 20 years ago and the 10 Japanese nuclear operators are all clients of the Cogema group. The 1997 turnover realized with Japan reached 3.6 billions of francs (11% of the total turnover of the group). This short paper presents briefly the nuclear program of Japan (nuclear park, spent fuels reprocessing-recycling strategy) and the contracts between Cogema and the Japanese nuclear operators (natural uranium, uranium conversion and enrichment, spent fuel reprocessing, plutonium recycle and MOX fuel production markets).

    During a 15-year joint research program, French Atomic Energy Agency Interactive Robotics Laboratory (CEA LIST) and AREVA have developed several remote operation devices, also called tele-robots. Some of them are now commonly used for maintenance operations at the AREVA NC (Nuclear Cycle) La Hague reprocessing plant. Since the first maintenance operation in 2005, several other successful interventions have been realized using the industrial MA23/RX170 tele-manipulation system. Moreover, since 2010, the through-the-wall tele-robot named MT200 TAO based on the slave arm of the MSM MT200 (La Calhene TM ), has been evaluated in an active production cell at the AREVA NC La Hague fuel recycling plant. Although these evaluations are ongoing, the positive results obtained have led to an update and industrialization program. All these developments are based on the same generic control platform, called TAO2000 V2. TAO2000 V2 is the second release of the CEA LIST core software platform dedicated to computer aided force-feedback tele-operation (TAO is the French acronym for computer aided tele-operation). This paper presents all these developments resulting from the joint research program CEA LIST/AREVA. The TAO2000 V2 controller is first detailed, and then two maintenance operations using the industrial robot RX170 are presented: the removal of the nuclear fuel dissolver wheel rollers and the cleanup of the dissolver wheel inter-bucket spaces. Finally, the new MT200 TAO system and its evaluations at the AREVA NC La Hague facilities are discussed. (authors)

    Nuclear measurements are used at AREVA NC/La Hague for the monitoring of spent fuel reprocessing. The process control is based on gamma-ray spectroscopy, passive neutron counting and active neutron interrogation, and gamma transmission measurements. The main objectives are criticality and safety, online process monitoring, and the determination of the residual fissile mass and activities in the metallic waste remained after fuel shearing and dissolution (empty hulls, grids, end pieces), which are put in radioactive waste drums before compaction. The whole monitoring system is composed of eight measurement stations which will be described in this paper. The main measurement stations no. 1, 3 and 7 are needed for criticality control. Before fuel element shearing for dissolution, station no. 1 allows determining the burn-up of the irradiated fuel by gamma-ray spectroscopy with HP Ge (high purity germanium) detectors. The burn-up is correlated to the 137 Cs and 134 Cs gamma emission rates. The fuel maximal mass which can be loaded in one bucket of the dissolver is estimated from the lowest burn-up fraction of the fuel element. Station no. 3 is dedicated to the control of the correct fuel dissolution, which is performed with a 137 Cs gamma ray measurement with a HP Ge detector. Station no. 7 allows estimating the residual fissile mass in the drums filled with the metallic residues, especially in the hulls, from passive neutron counting (spontaneous fission and alpha-n reactions) and active interrogation (fission prompt neutrons induced by a pulsed neutron generator) with proportional 3 He detectors. The measurement stations have been validated for the reprocessing of Uranium Oxide (UOX) fuels with a burn-up rate up to 60 GWd/t. This paper presents a brief overview of the current status of the nuclear measurement stations. (authors)

    The 'Groupe Radioecologie Nord Cotentin' (GRNC) has carried out a very thorough evaluation of the assessment of doses due to discharges from the Cap de la Hague nuclear site carried out by Areva NC, the site operators. The group has looked at all aspects of the assessment methods and data to ensure that they agree with the results presented in the 2006 annual environmental report of the operator. The computer tool, ACADIE, developed to assess the doses, has been used by the GRNC members to carry out their own calculations. This document comprises the detailed report of the GRNC and its synthesis. The detailed report includes: 1 - a critical analysis of the 2006 source term; a note about the uranium content in liquid effluents; the data transmitted by Areva NC (status of atmospheric effluents, status of liquid effluents at sea, fuel data); the data transmitted by the IRSN - the French institute of radiation protection and nuclear safety (status of the radioactive effluents of Areva La Hague facility); the history of liquid and gaseous effluents between 1966 and 2006; 2 - detailed comparison between model and 2006 measurements; critical analysis of 14 C and tritium data available for the Nord Cotentin and the English Channel area; 3 - detail of the 2006 efficient dose calculations; presentation of the environmental dispersion of tritium and of its effects on living organisms.

    Since 1965, the site of the Nez-de-Jobourg, in the Manche district and at the vicinity of the La Hague plant, has been a site of ornithological follow-up, notably because it harbours different population of nesting sea birds. Since 1990, it has been noticed that the population of European shags has been keeping on decreasing, with abnormally low birth rate, while the European herring gull has totally disappeared. If the relationship between this decline and the releases of the La Hague nuclear waste processing plant is easily and quickly suspected, other reasons are also plausible. The authors report a study of this decline and an investigation of its possible origins. After a presentation of the site, of its status regarding hunting and specie protection, and a presentation of other close sites (small islands, bay), the report addresses the case of the European shag. It gives information on its biology, characteristics, location and population, reproduction sites and nesting cycle. It presents the method adopted to test the various hypotheses of origin of the noticed decline: contamination by radioactive materials or by chemical substances, problems of disturbance by fishers, tourists or others, problems of predation, parasitism or lack of food resources. Samplings have been performed within the studied site and also within reference sites located some miles away. Based on data and observations, hypotheses are then discussed. An analytical report of measurement of artificial radio-elements performed by gamma spectrometry is provided

    As the pace of the French nuclear programme slackens off, Cogema is planning to compete even more vigorously in world fuel cycle markets. The company believes the foundations for success lie in its comprehensive range of fuel cycle activities, its status as a wholly-owned subsidiary of the Commissariat a l'Energie Atomique, and its experience in fulfilling the bulk of French fuel cycle needs. To build on these foundations, Cogema is exploring for uranium, investing heavily in new plant, and strengthening its commercial management. (author)

    Tison, E.; Bretault, Ph.

    2006-01-01

    Separation and purification of plutonium by PUREX process is based on a sequence of extraction and back extraction which requires reducing plutonium Pu IV (extractable form) into Pu III (inextractable form) Different reducers can be used to reduce Pu IV into Pu III. Early plants such as that for Magnox fuel at Sellafield used ferrous sulfamate while UP 1 at Marcoule used uranous sulfamate. These reducers are efficient and easy to prepare but generates ferric and/or sulphate ions and so complicates management of the wastes from the plutonium purification cycle. Recent plants such as UP3 and UP2 800 at La Hague, THORP at Sellafield, and RRP at Rokkasho Mura (currently under tests) use uranous nitrate (U IV) stabilized by hydrazinium nitrate (N 2 H 5 NO 3 ) and hydroxyl ammonium nitrate (HAN). In the French plants, uranous nitrate is used in U-Pu separation and alpha barrier and HAN is used in Pu purification. Compared to sulfamate, U IV does not generate extraneous chemical species and uranyl nitrate (U VI) generated by reducing Pu IV follows the main uranium stream. More over uranous nitrate is prepared from reprocessed purified uranyl nitrate taken at the outlet of the reprocessing plant. Hydrazine and HAN offer the advantage to be salt-free reagents. Uranous nitrate can be generated either by electrolysis or by catalytic hydrogenation process. Electrolytic process has been implemented in early plant UP 1 at Marcoule (when changing reducer from uranous sulfamate to uranous nitrate) and was used again in UP2 plant at La Hague. However, the electrolytic process presented several disadvantages such as a low conversion rate and problems associated with the use of mercury. Electrolysis cells with no mercury were developed for the Eurochemic plant in Belgium and then implemented in the first Japanese reprocessing plant in Tokai-Mura. But finally, in 1975, the electrolytic process was abandoned in favor of the catalytic hydrogenation process developed at La Hague. The

    The study contained in this report estimates the health effects in terms of doses to the populations due to the release of Iodine 129 from the marine outlet for the reprocessing plant located at La Hague. The release taken into account is due to the normal functioning of the plant, which introduces a consistent contamination of the English channel during the life of the plant which is thirty years. The annual release of Iodine 129, as assumed by the operating staff, is equal to either 1,662.10 12 Bq or 45 Ci. The dose equivalent to the thyroid of the concerned population due to normal consummation of marine products (fish, shell-fish, mollusc) are very low as compared to the 6.10 -4 limit of dose authorized for the public in the actual regulation. The effective dose equivalent has been estimated at 4.27.10 -7 Sv [fr

    1999-01-01

    The preliminary study of the 129 I distribution has allowed to underline the limits of use of a Homalotecium sericeum type terrestrial moss as biological indicator. However, this preliminary study allowed all the same to give a spatial distribution of this radioelement around La Hague reprocessing plant (source term) that underlines the existence of four geographic areas in function of collected activities. The levels are generally under 99 Bq/kg dry. It is recommended to improve the knowledge that we can have of transfers and quantity of iodine 129 from the marine environment to the terrestrial environment, but also, the one that we can have of factors able to modify the spatial distribution of this radionuclide.

  7. Modelling the transfer of 14C from the atmosphere to grass: A case study in a grass field near AREVA-NC La Hague

    Radioactive 14 C is formed as a by-product of nuclear power generation and from operation of nuclear fuel reprocessing plants like AREVA-NC La Hague (North France), which releases about 15 TBq per year of 14 C into the atmosphere. Since the autumn of 2006, 14 C activity concentrations in samples from the terrestrial environment (air, grass and soil) have been monitored monthly on grassland 2 km downwind of the reprocessing plant. The monitoring data provides an opportunity to validate radioecology models used to assess 14 C transfer to grassland ecosystems. This article compares and discusses the ability of two different models to reproduce the observed temporal variability in grass 14 C activity in the vicinity of AREVA-NC La Hague. These two models are the TOCATTA model which is specifically designed for modelling transfer of 14 C and tritium in the terrestrial environment, and PaSim, a pasture model for simulating grassland carbon and nitrogen cycling. Both TOCATTA and PaSim tend to under-estimate the magnitude of observed peaks in grass 14 C activity, although they reproduce the general trends. PaSim simulates 14 C activities in substrate and structural pools of the plant. We define a mean turn-over time for 14 C within the plant, which is based on both experimental data and the frequency of cuts. An adapted PaSim result is presented using the 15 and 20 day moving average results for the 14 C activity in the substrate pool, which shows a good match to the observations. This model reduces the Root Mean Square Error (RMSE) by nearly 40% in comparison to TOCATTA. - Highlights: ► We model 14 C transfer from the atmosphere to grass near AREVA-NC reprocessing plant. ► Both models considered under-estimate the observed variability and highest peaks. ► A model based solely on the sap 14 C activity and mean turn-over time is considered. ► It performs well and could be applied to case studies around nuclear facilities.

    {sup 60}Co is produced as an activation product and is present in the low-level aqueous radioactive waste released from the La Hague plant. At present, the concentration in the sea (non filtered at 0.45 {mu}m) at the Goury site are close to or even below, the detection limit: 0.2 mBq.l{sup -1}. The {sup 60}Co speciation depends on the type of effluent considered: in the effluent A ('active'), the cobalt is in the form of a stable trivalent complex; in the effluent V (to be checked), the cobalt is in majority (50% of the activity release) in the form of particles (>0.45 {mu}m), and then in the form of two soluble species: ionic divalent (Co{sup 2+}) and some stable complexes. The evolution of the reprocessing techniques used does not affect the speciation. So, since the nuclear reprocessing plant started at the La Hague plant in 1966, the chemical species discharged in the sea shows time variation related to the evolution of the type of effluent discharged. Thus, since 1994, the particles of cobalt are the main species discharged in the Channel (the V effluents represent more than 85% of the total {sup 60}Co activity released). The effect of instantaneous dilution into the marine conditions involving a variation of pH, oxido-reduction, ionic strength, a gradient of salinity, does not interfere with the evolution of the chemical species discharged. Nevertheless, during the discharge of the V effluent, the main constituents of the sea water (Mg{sup 2+} and Ca{sup 2+}) go through a precipitation. This comes with the coprecipitation of the ion Co{sup 2+} and with the particles of cobalt (complexes are not affected), and it can be responsible for an increase in the concentration in the particles. The chemical behaviour of the cobalt in the Channel is different from those of conservative element such as antimony. The ionic cobalt and the particles have a small dispersion in the water (cobalt has a very high particle/dissolved distribution factor, it is a non

    Goals of COGEMA's advertising campaign concerning nuclear fuel recycling are to: speak out in an area where COGEMA has legitimacy and is expected; and to take part in the discussion to support and defend an activity that is important for COGEMA. Targets are: back up opinion relays by reaching the general public; and back COGEMA personnel. The advertising strategy can be defined as follows: what is recommended for other industries (sorting and then recycling) is COGEMA's practice for spent fuel, with very significant advantages for the community in terms of economy and ecology

    The 'Groupe Radioecologie Nord Cotentin' (GRNC) has carried out a very thorough evaluation of the assessment of doses due to discharges from the Cap de la Hague nuclear site carried out by Areva NC, the site operators. The group has looked at all aspects of the assessment methods and data to ensure that they agree with the results presented in the 2006 annual environmental report of the operator. The computer tool, ACADIE, developed to assess the doses, has been used by the GRNC members to carry out their own calculations. This document comprises the detailed report of the GRNC and its synthesis. The detailed report includes: 1 - a critical analysis of the 2006 source term; a note about the uranium content in liquid effluents; the data transmitted by Areva NC (status of atmospheric effluents, status of liquid effluents at sea, fuel data); the data transmitted by the IRSN - the French institute of radiation protection and nuclear safety (status of the radioactive effluents of Areva La Hague facility); the history of liquid and gaseous effluents between 1966 and 2006; 2 - detailed comparison between model and 2006 measurements; critical analysis of {sup 14}C and tritium data available for the Nord Cotentin and the English Channel area; 3 - detail of the 2006 efficient dose calculations; presentation of the environmental dispersion of tritium and of its effects on living organisms.

    The preliminary study of the {sup 129}I distribution has allowed to underline the limits of use of a Homalotecium sericeum type terrestrial moss as biological indicator. However, this preliminary study allowed all the same to give a spatial distribution of this radioelement around La Hague reprocessing plant (source term) that underlines the existence of four geographic areas in function of collected activities. The levels are generally under 99 Bq/kg dry. It is recommended to improve the knowledge that we can have of transfers and quantity of iodine 129 from the marine environment to the terrestrial environment, but also, the one that we can have of factors able to modify the spatial distribution of this radionuclide.

  1. Decommissioning of nuclear facilities: COGEMA expertise devoted to UP1 reprocessing plant dismantling programme

    2001-01-01

    Over the last past decades, the French nuclear industry has acquired a great experience and know-how in the field of dismantling. Today this experience amounts to more than 200,000 hours. The fundamental aims within dismantling strategy are the same as for all nuclear facilities: minimising doses received by workers, minimising waste volume and adapting waste management to radioactivity levels, minimising costs. French experience is based on technologies which are currently used in nuclear maintenance facilities. Dismantling is a dynamic process especially in the field of decontamination (chemical and mechanical), cleaning, robotics and remote control operations. The strategy for the dismantling of former UP1 reprocessing plant is based on the feedback of experience gained through the dismantling of other facilities such as the AT1 workshop at La Hague. This workshop, a pilot plant for reprocessing of fast-breeder reactor fuels (Rapsodie and Phenix) has to be dismantled to IAEA level 3 (unrestricted site use), excluding civil works structures. Currently conducted by trained shifts, this dismantling project should end in 1999. The experience already acquired proves that chemical rinsings with the use of specific reagents is sufficient to decontaminate the hot cells and that the use of remote operations or robotics is not as important as previously envisaged. The UP1 reprocessing plant of Marcoule operated from 1958 to 1997. End of the operation was pronounced on the 31st of December 1997. 20,000 tons of spent fuels were reprocessed at UP1. The cleaning and dismantling operations at the Marcoule site depend upon the CEA, EDF and COGEMA. The Defence and Industry Ministries asked for a specific structure to be set up. An economic interest group called CODEM was created in May 1996. CODEM decides, finances and supervises dismantling operations, while respecting the constraints of nuclear safety, environmental protection and cost-effectiveness. The cleaning operations of

  10. COGEMA/TRANSNUCLEAIRE's experience with burnup credit

    International Nuclear Information System (INIS)

    Chanzy, Y.; Guillou, E.

    1998-01-01

    Facing a continuous increase in the fuel enrichments, COGEMA and TRANSNUCLEAIRE have implemented step by step a burnup credit programme to improve the capacity of their equipment without major physical modification. Many authorizations have been granted by the French competent authority in wet storage, reprocessing and transport since 1981. As concerns transport, numerous authorizations have been validated by foreign competent authorities. Up to now, those authorizations are restricted to PWR Fuel type assemblies made of enriched uranium. The characterization of the irradiated fuel and the reactivity of the systems are evaluated by calculations performed with well qualified French codes developed by the CEA (French Atomic Energy Commission): CESAR as a depletion code and APPOLO-MORET as a criticality code. The authorizations are based on the assurance that the burnup considered is met on the least irradiated part of the fuel assemblies. Besides, the most reactive configuration is calculated and the burnup credit is restricted to major actinides only. This conservative approach allows not to take credit for any axial profile. On the operational side, the procedures have been reevaluated to avoid misloadings and a burnup verification is made before transport, storage and reprocessing. Depending on the level of burnup credit, it consists of a qualitative (go/no-go) verification or of a quantitative measurement. Thus the use of burnup credit is now a common practice in France and Germany and new improvements are still in progress: extended qualifications of the codes are made to enable the use of six selected fission products in the criticality evaluations.

    The main objective of this paper is to assess the Bonn-Marrakech agreement, in terms of abatement cost and emission trading as compared with the initial agreement reached in Kyoto (the Kyoto Protocol). Our reference case (the Initial Deal) does not include the use of sinks credits, as the Kyoto Protocol does not give explicit figures nor method to estimate them. In addition, two hypothetical situations are considered. The first describes the ''missed compromise'' that could have emerged among all Parties in November 2000 in The Hague. The second is a virtual case where the US is assumed to be part of the Bonn-Marrakech Agreement, along with all the other Parties. These two cases contribute to shed the light on the Bonn-Marrakech Agreement potential pitfalls. In the current situation, the US is out of the negotiation process and has no emission reduction commitment. Given the projections of carbon dioxide (CO{sub 2}) emissions used in this study, the Former Soviet Union countries (FSU) and the Eastern European Economies (EEE) that are part of the Annex B have potentially enough Hot Air to fulfill the overall commitment of the Annex B bubble, without any domestic abatement effort from the other Annex B countries. We show that in the theoretical case where no limit would be imposed on the selling of Hot Air, the permit price according to the POLES model would be zero as no market equilibrium could take place. This is why, next, we examine the economic impacts of restrictions to hot air trading, for FSU and EEE as well as for the other countries. We shed the light on the potential market power of the former countries that arises from the Bonn-Marrakech Agreement. (author)

    The purpose of this paper is to show what we are doing in the area of environmental monitoring and control in accordance with the basic principles we set out for ourselves. As we have seen, our objectives are twofold; first, to monitor the installations under normal operating conditions in accordance with the rules and within the imposed limits and, secondly, in the event of an accident involving any of the material at the plant, to determine the foreseeable consequences in order to provide the relevant authorities, who have to take the necessary measures to protect the personnel and the population, with all the help they need. Normal operation is guaranteed by effective control of liquid and gaseous discharges, by knowing the precise origin and nature of the radio-elements released and also the means of transfer leading to humans. This knowledge relies upon the interpretation of the systematic measurements which have been carried out, which can only be done by centralising and computerising the data involved. The use of third-generation radio protection equipment in combination with highly-developed computer systems has made it possible to set up a centralised environmental control station. In the event of abnormal occurrences, the software used to show the transfer of radio-elements in the air, the water, or the ground, along with the use of systematic measurements, makes it possible to determine the foreseeable consequences and to design a system of predictive monitoring. It has been possible to set up the centralised control system because of the development in computerised equipment and systems, but it has only been possible to operate this system because of the capacity of the personnel to adapt to the changeover to technology.

  16. Cogema and the recycling of nuclear military materials

    International Nuclear Information System (INIS)

    1999-04-01

    The signature of the Start 1 and Start 2 treaties in 1991 and 1993 has marked the start-up of nuclear disarmament. This process covers two aspects: the destruction of vectors (missiles, planes..) and the dismantling of warheads carrying weapon grade radioactive materials (uranium and plutonium). This dossier explains the political and technical choices made by Russia and the USA for the management of their weapon grade plutonium: fabrication of MOX fuels (cooperation between Minatom (Russia), Siemens and Cogema for the building of conversion and fabrication plants, collaboration between Cogema, Duke Engineering and Stone and Webster (DCS) for the building of a MOX fabrication plant and for the irradiation of MOX fuels in US reactors), disposal of hardly convertible plutonium.

    This short article gives some financial informations about the Cogema group for 1996. The net result for 1996 reached 977 millions of French Francs (FF) with respect to 973 for the previous year. The turnover reached 34.427 billions of FF in 1996 and 30.611 in 1995, which represents a 12.5% growth. In the mining sector, the turnover has decreased to 2.853 billions of FF with respect to 3.238 in 1995. In the engineering and industry services sector the turnover of the overall companies, with the exception of Cogema, has considerably progressed (2.199 billions of FF in 1996, 1.738 in 1995). (J.S.)

    A radioecological study has been performed around the La-Hague nuclear reprocessing plant (Nord-Cotentin, France). The Working Group included nuclear operators, authorities, international experts and members of environmental organisations and was supported by IPSN. The study aimed to reconstruct radiation doses received by members of the public aged 0 to 24 years and living in the area, with a view to estimate the associated risk of leukaemia between 1978 and 1996. The assessment involved three steps: 1. reconstruction of a cohort of people aged 0 to 24 years, using local birth rates for the years 1954 to 1996 and taking into account the additional migrations of young people in the area. 2. estimation of doses to the red bone marrow received from all source of radiation (natural, medical, local nuclear industries and Chernobyl and weapons testing). Concentrations of radionuclides in the environment were estimated with a combination of two approaches: the modelling of the transfer of the releases in the environment and the use of environmental measurements. The dose computation takes into account the life style of the local population. ICRP dose coefficients to the red bone marrow were used. 3. derivation of leukaemia risk from a dose response model recommended by the UNSCEAR committee. The reconstructed population includes 6656 people born between 1954 and 1996, who inhabited the study area for at least one year between 1978 and 1996 before the age of 25. The number of person-years between 1978 and 1996 is 69308. The total collective dose to the red bone marrow due to local nuclear installations is 0.5 man.Sv. For the sake of comparison, the collective dose due to all sources of exposure is 241 man.Sv: The estimated number of leukaemia due to all exposure sources is 0.835. 74% are due to natural exposures, 24% to medical ones and 2% to the Chemobyl accident and nuclear arm testing. Nuclear facilities of Nord-Cotentin contribute only for 0.1% (between 0.0009 and 0

  4. Production from new uranium mines a Cogema resources Saskatchewan perspective

    International Nuclear Information System (INIS)

    Pollock, B.

    2001-01-01

    The province of Saskatchewan is best known for the large flat tracts of land in the south that are primarily used for agricultural purposes. Less well known is the fact that the northern part of the province hosts the richest uranium mines in the world. In fact, to use a petroleum analogy, Saskatchewan has been referred to as the 'Saudi Arabia' of the uranium producing countries. The mining industry in Saskatchewan is a flourishing, high technology industry and supplies approximately one-third of the annual world primary production of uranium. The purpose of this paper is to examine the uranium mining industry in Saskatchewan and why this province stands alone as the dominant uranium producer in the world and will maintain that position into the foreseeable future. As well, an overview of the significant role played by COGEMA Resources in developing the Saskatchewan uranium industry will be undertaken. This company whose roots date back almost 40 years in the province, now holds significant interests in all four of the mines currently producing uranium. With investments of over one billion dollars (U.S.) in this province, COGEMA has established itself as a long-term player in the Saskatchewan Uranium Industry. (author)

    After having briefly recalled the activities of COGEMA's subsidies in Niger, presented the context of the inquiry, and made some remarks about COGEMA's attitude with respect to this inquiry, this report gives an extremely critical analysis of security measures and working conditions: non existent information about risks related to radioactivity, non existent or insufficient security equipment, exposure of workers to ionizing radiation by water, ignored security orders, random dosimetry controls. The second part recalls the radiological risks present in uranium mines, gives a critical analysis of the worker medical follow-up quality, considers as inexplicable the absence of professional diseases, and discusses the issue of work accidents. It finally outlines that control structures (Mine Direction, Work Inspection) are inadequate

    It has often been argued for the effect of defences provided to carriers under Art IV (2) of Hague Visby Rules to almost nullify the protection guaranteed to shippers in other provisions of this convention. Therefore an all embracing universal shipper friendly convention, merely the Hamburg Rules, need be incorporated in all countries in order to address this issue and fully satisfy the intentions of the parties for the establishment of international rules in international trade

    Ramsey-type results dictate that an optimal pattern of taxes must tax more heavily those goods which have a more inelastic(compensated)demand. Corlett and Hague (1953) investigated the optimal revenue-neutral movements from an initial uniform tax. They obtained that the goods (relatively) more complementary to the untaxed good (leisure)should see their taxes increased-which in a revenue-neutral seeting implies that the other goods see their taxes disminished.

  12. Safety highlights of UP2 reprocessing in La Hague

    International Nuclear Information System (INIS)

    Marc, A.; Dubois, G.

    1998-01-01

    The UP2-800 reprocessing plant basically implements the same proven process (PUREX) as UP3 plant. However, some evolutions and additions have been realised: - to reprocess high burn up and MOX fuel assemblies; - to dissolve scraps from reprocessing facilities or from the fabrication of MOX fuels such as UO 2 - PuO 2 powders; - to recover plutonium from ash resulting from alpha waste incineration prior to ash conditioning; - to reduce solid waste alpha activity below the regulatory limits for shallow land disposal. Safety considerations relating to these functions have been taken into account in each step of process design. Safety design rules have been implemented for the UP2-800 plant with the same goals as for the UP3 plant: - keeping the discharge of radioactive liquids and gas within the annual limits authorized under normal operating conditions; - reducing the personnel exposure to a minimum so that 'the number of operators whose integrated dose over a year exceeds 5 mSv be nil or practically nil under normal operating conditions'; - preventing the accidental situations and having at one's disposal the dysfunction monitoring and detection systems and the means to limit their consequences. Particular risks prevention related to the UP2-800 specific functions are described in this paper. (author)

    1991-01-01

    The management of the solvent in the reprocessing plants has always been a difficult problem. Various process reasons lead to discard some contaminated solvent: this spent solvent is an organic waste the volume of which must be minimized. To solve this problem for the UP3 plant, it has been decided to implement a distillation facility in order to split this spent solvent into three parts: recovered diluent and concentrated TBP, to be recycled in the extraction process, and a residue which contain the radioactivity and most of the impurities. As the TBP is not highly volatile and as it is a thermosensitive compound, this distillation is performed at low pressure and temperature, with thin films evaporators, in order to minimize the residence times in heated zones. The paper describes the selected process and the equipment employed. The R and D work which has been performed to define the process, size up the equipment and demonstrate the process is described, including the laboratory works, the pilot plant tests and the results of tests performed with a full scale prototype which has been built to demonstrate the whole process. The industrial facility is described, and the results of the first active runs are described briefly. (author)

    Cancer mortality of the nuclear workers of CEA and COGEMA has been collected by the occupational health services of both firms from 1969 to 1986. The data are related only to the workers who died when in activity. Only very few workers left CEA and COGEMA before retirement so we consider this mortality survey as describing correctly the cancer mortality for the age groups less than 60-65 years old. Compared to the national mortality of same sex, age and calendar period, by the method of indirect standardization, the only excess observed was in the female population, linked to breast cancer mortality. The male population demonstrated a high healthy worker effect, even for cancer mortality. This study has now to be completed by an typical epidemiological cohort study in order to test cancer mortality after retirement and to discuss a possible relation with occupational exposure.

    International Nuclear Information System (INIS)

    2001-01-01

    The Centre de la Manche disposal facility, created by decree in 1969, is the first French near-surface radioactive waste disposal facility. It lies at the northwest end of the Cotentin peninsula, next to the COGEMA-La Hague fuel reprocessing plant. The Centre de la Manche facility occupies an area of about 150,000 m 2 . Its operation was terminated in late June 1994 with about 500,000 m 3 of packages disposed of. Operating feedback from the Centre de la Manche was used to design the second French disposal facility, located in the Aube, which has been receiving LILW since 1992. Since the end of the operating period, ANDRA has been preparing the statutory files to prepare the Centre de la Manche for its entry into the institutional control period. A new government decree will set the framework in which the Centre will evolve in this period. The regulatory process includes the filing of an application with the ministries concerned, containing a file with the requisite statutory documents, including an impact study of the facility on its environment as well as a hazard study. The file will then be submitted to a public inquiry, an essential informative period of the project designed to make a compilation of criticisms and suggestions from the public. In support of the application, a safety report has been sent to the Nuclear Installation Safety Directorate (DSIN) for a decision on the admissibility of the application. Recently, the Group of experts appointed by the DSIN which examined it has come out in favor of the creation of a new basic nuclear installation (i.e., a new government agency) for the institutional control period. A draft decree will then be submitted to the approval of the Interministerial Commission for Basic Nuclear Installations. This process, initiated in 1994, is nearing completion

    Ca-DTPA has been used for medical treatment of plutonium and americium contaminations in the CEA and COGEMA plants from 1970 to 2003. This report is a survey of the injections administered of Ca-DTPA as a chelating molecule. This report will be a part of the AMM process for Ca-DTPA by intravenous administration submitted by the Central Pharmacy of the french Army. Out of 1158 injections administered to 469 persons, 548 events of possible or confirmed contaminations were reported. These employees were followed by occupational physicians according to the current regulations. The first part of the report is a synthesis of the most recent findings. Due to its short biological period and its limited action in the blood, Ca-DTPA does not chelate with plutonium and americium as soon as these elements are deposited in the target organs. It justifies an early treatment, even in cases of suspected contamination followed by additional injections if necessary. The second part presents data concerning these 1158 injections (way of contamination, posology, adverse effects...). These incidents took place at work, were most often minor, not requiring follow-up treatment. A study concerning the effectiveness of the product was done on a group of people having received 5 or more injections. These results were compared with effectiveness estimated from theoretical basis. Posologies and therapeutic schemes were proposed based on these observations. Additional studies are needed to confirm these findings. This document is the first synthesis in this field. It is the result of a collective work having mobilized the occupational medicine departments, the laboratories of CEA and COGEMA and a working group CEA-COGEMA-SPRA. (authors)

    This paper investigates the occurrences at the Sixth Conference of the Parties (CoP) to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) which took place in The Hague, Netherlands, from 13-25 November of 2000. Since the conference did not reach an agreement there exists a broad interest in knowing what really happened during the negotiations. The aim of the analysis is to give greater insight to reasons of the climate talks' failure and to progress made during the negotiations. Following the discussions of the issues surrounding the talks in The Hague, the paper will also look forward as to possible solutions and ideas for an eventual agreement

    After a description of the uranium exploitation context (involved companies, production) in Arlit, Niger, by Cogema-Areva subsidiary companies, this report describes the context of controls performed by the CRIIRAD laboratory. Then, it reports and comments the contamination of underground so-called drinkable waters (contamination risks, Cogema statement, detection of a rather high concentration of alpha emitters, measurements performed in 2004 and 2005). The authors notice that water contamination is known by Cogema. Then, the report analyzes the issue of contaminated scrap metal dispersal, comments and criticizes the attitude of Cogema with respect to the associated risks. It comments the uranate transport accident which occurred in February 2004, the subsequent contamination, actions performed by Cogema, the associated health risks, and the statements made by Areva and Cogema. It also comments and analyzes the risks related to radioactive radon dusts inhalation around different sites and because of some technical practices, and Cogema statements about this issue. In conclusion, the authors outline the need of reinforced controls and of an epidemiological study, and outlines how Areva propagates wrong ideas

In the RRFM'98 meeting, a joint contribution of CEA, CERCA and COGEMA presented a technical classification of the potential candidates uranium alloys. In this paper this MTR working group presents the development program of a new high density fuel. This program is composed of three main steps: Basic Data analysis and collection, Plate Tests (Irradiation and Post Irradiation Examinations) and Lead Test Assemblies (Irradiation and Post Irradiation Examinations). The goal to be reached is to make this new fuel available before the end of the present US return policy. (author)

    The present study follows 9287 Cogema workers exposed to low level of ionizing radiation from the beginning of employment to the end of 1994. This paper presents analyses of the mortality of Cogema workers monitored for external radiation exposure and the relation between their mortality and their cumulative external radiation dose. Workers were followed up for an average of 13 years. The percentage of subjects lost to follow up was less than 1%. during the follow-up period, 441 deaths occurred. The mean cumulative dose among the whole cohort was 19.4 mSv. As expected, the mortality of the cohort was lower than that of the French national population. The healthy worker effect is often observed in other nuclear workers studies. Part of the healthy worker effect is explained by a proportion of unemployed persons in general population, with a higher mortality rate. All causes S.M.R. increased with calendar period and duration of employment. this increase was not significant for all cancers S.M.R. by duration of employment. This could illustrate the decrease of the initial selection at employment with time. A significant increase in risk was observed for all cancers excluding leukemia mortality with increase of radiation dose in the 15-country study. Significant excess of leukemia by cumulative radiation exposure was observed in the 3-country study and was borderline significant in the 15-country study and in the UK National register for radiation workers study. A positive trend, not statistically significant, by level of external doses was observed in our study for all cancers and leukemia excluding chronic lymphatic leukemia mortality, but the analyses lack of statistical power. A significant trend was observed only for non-Hodgkin lymphoma death, but considering the large number of statistic tests computed, this result must be carefully interpreted. A borderline significant trend was observed for lung cancer death, a significant increase risk of lung cancer death

To accompany the 'nuclear renaissance' and the related fuel design and fuel management evolution, it is crucial to anticipate the associated needs in terms of cask development notably for the spent fuel management. It is the reason why an ambitious R and D program has been set up at COGEMA Logistics. It aims at proposing innovative solutions oriented by the trends guiding this 'renaissance': the proposed systems have indeed to accommodate Spent Fuel Assemblies (SFAs) characterized by ever increasing burn-ups, fissile isotopes contents, and total inventory. Flexibility may potentially mean quick evacuation of UO{sub 2} or MOX spent fuel with high thermal power to be dealt with.

  2. One year's experience by COGEMA logistics of application of the new modal regulations

    International Nuclear Information System (INIS)

    Malesys, P.

    2002-01-01

    International transport of radioactive materials is regulated by international and regional modal regulations that apply to all dangerous goods. The requirements for radioactive materials in the modal regulations are based on those of the 'Regulations for the Safe Transport of Radioactive Material' set forth by the International Atomic Energy Agency (IAEA). The last edition of the IAEA regulations was published in 1996 (TS-R-1 (ST-1, Revised)), then incorporated in the modal regulations, and finally implemented, with various transitional periods throughout 2001. As a final result, since 1 January 2002 it has been mandatory, for all modes, to perform transports in accordance with the 1996 edition of the IAEA transport regulations. In the mean time, all the international and regional regulations have also been reformatted, and each of them has now adopted the unified format of the United Nations 'Recommendations on the Transport of Dangerous Goods - Model Regulations', often referred to as the Orange Book. This paper presents the experience of COGEMA Logistics with the application of this new set of regulations to design of packages, transport operations, and administrative matters. Both the advantages provided by these new regulations and the difficulties which were (and are still being) met are presented. (author)

    Ca-DTPA has been used for medical treatment of plutonium and americium contaminations in the CEA and COGEMA plants from 1970 to 2003. This report is a survey of the injections administered of Ca-DTPA as a chelating molecule. This report will be a part of the AMM process for Ca-DTPA by intravenous administration submitted by the Central Pharmacy of the french Army. Out of 1158 injections administered to 469 persons, 548 events of possible or confirmed contaminations were reported. These employees were followed by occupational physicians according to the current regulations. The first part of the report is a synthesis of the most recent findings. Due to its short biological period and its limited action in the blood, Ca-DTPA does not chelate with plutonium and americium as soon as these elements are deposited in the target organs. It justifies an early treatment, even in cases of suspected contamination followed by additional injections if necessary. The second part presents data concerning these 1158 injections (way of contamination, posology, adverse effects...). These incidents took place at work, were most often minor, not requiring follow-up treatment. A study concerning the effectiveness of the product was done on a group of people having received 5 or more injections. These results were compared with effectiveness estimated from theoretical basis. Posologies and therapeutic schemes were proposed based on these observations. Additional studies are needed to confirm these findings. This document is the first synthesis in this field. It is the result of a collective work having mobilized the occupational medicine departments, the laboratories of CEA and COGEMA and a working group CEA-COGEMA-SPRA. (authors)

    1830–1870 The Hague underwent considerable densification inside the canal ring as well as extensions north and south of the city. The number of new tenements built on inner yards in The Hague can give a distorted impression, as can the number of demolished buildings in Leiden, because the 1870 maps were much more detailed. In Leiden the advent of new factories prompted new construction on the former city walls. The Hague, too, became a major industrial player, while continuing to profit from its function as the centre of government. In 1870, The Hague had almost twoand-a-half times as many inhabitants as Leiden (92,000 versus 39,000, but within the canal girdle Leiden was still more densely built up. Between 1700 and 1870, The Hague developed into one of the Netherlands’ biggest cities, which it still is. Leiden plummeted from second place to the middle bracket, where it continues to sit today.

    2013-05-01

    Full Text Available The study premises and objectives: The idea found at the basis of the discovery of a real value of cultural goods is underlined by the knowledge of their origins and history and of an environmental frame in which these have been produced. This theory could also be applied in regulations provided with certain newly introduced elements as: the absolute interdiction of thefts; the interdiction of destruction and execution of enemy property; the warning of before a terrestrial bombing with naval forces of ports, cities, villages, buildings or houses which are not defended The purpose on this paper is based on the following question: “Which of the gaps of humanitarian international law regarding cultural goods are surfacing?” The research models used are: the interpretative method, the structuralist-systematic method necessary for the knowledge of rules of organization and functioning of law as a system of social organization; the epistemological method, with an important role in the verification of an authentic meaning, fully manifesting the exigency regarding the protection of cultural property. The result of the study is obtained by offering an answer which as argued in this paper, concluding on one side that the discrepancies appeared between provisions (or dispositions of the Hague Convention of 1907 and the events of the First World War have led to an improved idea and to a completion of these norms. Conclusions: The preoccupation for the protection of cultural goods, of the people’s cultural patrimony, thus continues, even if, despite all acts adopted, we observe that certain states destroy willingly the treasures of other peoples. We have thus reached the conclusion that more drastic measures must be adopted more severe sanctions must be applied to states that neglect the norms of humanitarian international law and the existent gaps must be eliminated. For this reason the Second Protocol of The Hague Convention of 1954 has been promoted

The analysis covers the international market of emission rights, a key mechanism of the Protocol, the purpose of which is to facilitate the Parties' compliance with their undertakings, by introducing flexibility to improve the economic efficiency of emission reduction. However, it now appears that despite the Marrakech agreement in November 2001, the system is weakened by the withdrawal of the USA decided by President G.W. Bush in March 2001, following COP 6 in The Hague, and by a potential excess of permits due to the economic recession of transition countries since the early nineties (hot air). As things stands, the establishment of the market between the countries taking part in the process will undoubtedly require some management of this hot air between transition countries (Eastern Europe and Ex USSR) and the other Parties of appendix B still involved in the process. The uncertainties weighing on the future market of emission permits strengthen the strategic significance of the implementation of effective reduction policies within those regions and particularly within Europe.

    After more than 30 years of Spent Fuel Nuclear Fuel (SFN) and High Level Waste (HLW) casks shipments to and from the COGEMA reprocessing factories in LA HAGUE, COGEMA LOGISTICS has demonstrated a unique outstanding performance in transportation for the benefit of its international customers and has integrated all feed-back from past successful operations. While maintaining the highest safety and security records, the last 5 years have been a major challenge to overcome the increase in transport throughputs, regulatory requirements, specific customer demands and new environmental approach (both COGEMA-La Hague and COGEMA LOGISTICS have been certified ISO14001 since 2003). Improvements in procedures, equipments, controls, inspection and organization have been undertaken. Additional important logistics means such as cranes, lifting devices, spreaders were put in operations in the dedicated workshop of our road and maritime facilities as well as in our rail terminals. Thus COGEMA LOGISTICS has developed and improved important logistics means in the Cherbourg area for the loading and unloading operations of heavy casks (i.e. whose weight is between 25 and 120 tons) among three modes of freight (road, railway or maritime transportation). In Valognes, which is currently the most important railway terminal in the world for the transfer of nuclear materials, about 1200 transfers of heavy casks were performed in 2003. New transport equipment and assets were integrated successfully to answer the new requirements for the best interest of our customers. This paper will provide information about equipments and management system developed to overcome these challenges.

    Sert, G.; Savornin, B.; Rouquette, Y.

    1989-01-01

    The reprocessing of spent fuel generates different kinds of wastes. Among them fission products and non fissile actinides represent 98% of the radioactivity; these wastes are separated, concentrated, mixed with molten glass and poured into stainless steel containers. For political reasons, it is necessary to return these vitrified high activity wastes to the foreign countries which have decided to have their spent fuel reprocessed in France. So the transport of vitrified waste is vital for both the reprocessor and the utilities that have trusted the reprocessor and this operation has to be securely performed to give satisfaction to all concerned particles. For that reason Cogema will control the whole transport activity from La Hague plants to the receiving facilities of the customers. Therefore cogema will be responsible of the transport whatever the cask type (transport or storage) and will subcontract the transport operation to experienced companies such as Transnucleaire, PNTL or NTL, who will act on behalf of Cogema. Cogema will be the owner of the transport casks while the storage casks will normally be owned by the customers. Both cask types will of course have to comply with the requirements of La Hague, as published by Cogema

    1995-01-01

    In the frame of COGEMA actins to reduce the volume of the reprocessing waste, a new strategy of drumming and incinerating is going to start at LA HAGUE and MARCOULE, for the low level waste planned for surface storage. This strategy depends on the performance improvement of non destructive measurements systems used for the alpha waste evaluation. In this global, closer links between COGEMA, SGN, CEA and EURYSIS MESURE have taken place to define a program in order to obtain up to three years the required performances, using active methods with neutron generator. These developments and tests are carried out on the PROMETHEE R and D facility at CEA-CADARACHE. (authors)

    Burn-up credit can be defined as making allowance for absorbent radioactive isotopes in criticality studies, in order to optimise safety margins and avoid over-engineering of nuclear facilities. As far as the COGEMA Group is concerned, the three fields in which burn-up credit proves to be an advantage are the transport of spent fuel assemblies, their interim storage in spent fuel pools and reprocessing. In the case of transport, burn-up credit means that cask size do not need to be altered, despite an increase in the initial enrichment of the fuel assemblies. Burn-up credit also makes it possible to offer new cask designs with higher capacity. Burn-up credit means that fuel assemblies with a higher initial enrichment can be put into interim storage in existing facilities and opens the way to the possibility of more compact ones. As far as reprocessing is concerned, burn-up credit makes it possible to keep up current production rates, despite an increase in the initial enrichment of the fuel assemblies being reprocessed. In collaboration with the French Atomic Energy Commission and the Institute for Nuclear Safety and Protection, the COGEMA Group is participating in an extensive experimental programme and working to qualify criticality and fuel depletion computer codes. The research programme currently underway should mean that by 2003, allowance will be made for fission products in criticality safety analysis

    Full Text Available This article discusses an unpublished play, Acteonisation du Grand Veneur d’Hollande (1643. Created – and possibly performed – within the immediate circle of the court of Elizabeth of Bohemia in The Hague, its anonymous author satirizes the various personalities in the Orange courts of respectively Frederik Hendrik and Amalia von Solms, and Willem II and Mary Stuart. Focusing on the social ambitions of Johannes Polyander van Kerckhoven, Lord of Heenvliet, and by using the popular myth of Actaeon and Diana, the clash between court and city, between princely aristocrats and republican burghers is played out.

    International Nuclear Information System (INIS)

    Auziere, P.; Thomasson, J.

    2002-01-01

    A wide range of Research Test Reactor aluminide type spent fuel is already received for treatment conditioning at the La Hague reprocessing complex. Such a diversity calls for an utmost attention to be paid to all safety-related systems and technical aspects, to all regulatory and administrative constraints. Despite of such multiple data inputs and rigid constraints, a close cooperation between the Research Reactor operator and COGEMA enables to reach adequate and cost effective solutions also relevant to spent fuel having had an uneven history. The acceptance process is primarily based on the client descriptive data and status declaration issued by the Research Reactor (RR) operator under QA. This acceptance process is a key step, to be keenly scheduled as it is directly interactive with the RR evacuation plans and the La Hague industrial plant program. It is also governed by the reviews conducted by the French Safety Authority and generally translated into operational authorisations. Concerned by maintaining high safety standards, reliable and proven operational levels of its nuclear services performed in the La Hague facilities COGEMA includes, all through this acceptance process, the operating, regulatory and administrative requirements. This paper sets forth an overview of the approach implemented in the COGEMA organisation for the management of the acceptance process of RTR aluminide type spent fuel. (author)

    1993-01-01

    The French 'Compagnie Generale des Matieres Nucleaires' - COGEMA - is involved in the whole nuclear fuel cycle about 20 years. Among the different parts of the cycle, the Transport of Radioactive Materials, acting as a link between the differents plants has a great importance. As nuclear material transportation is the only fuel cycle step to be performed on public grounds, the industrial task has to be performed with the utmost stringent safety criteria. COGEMA and associates is now operating a fully mature commercial activity, with some 300 spent fuel shipments per year from its reprocessing customer's reactors to the LA HAGUE plant, either by rail, road or sea. The paper will review the organization of COGEMA transportation business, the level of technology with an update of the casks used for spent fuel, and the operational experience, with a particular view of the maintenance policy.

    In France, the reprocessing of spent fuels is the solution that has been retained for the management of the end-of-cycle. The sorting of the different components of spent fuels allows the recycling of uranium and plutonium for the further production of enriched uranium and mixed oxide fuels. This paper presents Cogema's advances in this domain (facilities and plants), the transfer of Cogema's reprocessing and recycling technologies in other countries (Japan, USA, Russia), the economical and environmental advantages of the recycling of spent fuels, the economical resources provided by this activity, and the cooperation with foreign countries for the reprocessing of their spent fuels at Cogema-La Hague.

    In a first text, the author briefly describes the radioprotection risks related to uranium mining, gives an overview of the characteristics of extraction residues in uranium extraction factories. Then, after having presented the case of the Limousin region in France, he outlines the high level of contamination of the environment of the mining sites, recalls the extraction process and discusses the careless use of the extracted radioactive rocks and materials. He outlines the insufficient management and processing of liquid effluents, the risk associated with the dispersal of contaminated scrap metals and of radioactive ores. He also discusses air contamination due to dusts and radioactive gases. He comments the issue of long term storage of uranium mining residues. He outlines the responsibility of the Administration and comments the trial against Cogema which took place in 2005. He outlines how restructuring of all the concerned sites is a challenging issue for our future. A second text in English describes radiological hazards from uranium mining (uranium by-products, radiological situation before and during extraction, long term contamination after mines closure, problems posed by tailing disposal)

  7. TN trademark FLEX: a new generation of fluorocarbon o-rings developed by COGEMA logistics with enhanced characteristics at low temperature (-40 C)

    International Nuclear Information System (INIS)

    Issard, H.; Andre, R.

    2004-01-01

    Three main types of elastomers are used for the sealing of radioactive material transport casks with elastomeric gaskets: EPDM, fluorocarbons type Viton registered (standard designation: FKM) and silicon rubbers. Each rubber has specific characteristics in terms of temperature range, permeability, coefficient of expansion.. For the casks where high temperatures can be reached (200 C in continuous using), FKM gaskets are generally used. The problem is that this type of gasket does not guarantee the leaktightness at -40 C, which is a regulatory requirement. Two solutions are generally used: to specify a minimum heat load or a minimum ambient temperature. The direct consequence is that it is impossible to get B(U) approvals on the new concepts when FKM gaskets are used but only B(M) approvals, which generate significant additional justification costs (multiple submittals of Safety Analysis Reports, calculation of the minimum heat load or of the minimum ambient temperature..). Thus, it is important to develop gaskets with the same performance as FKM gaskets at high temperature but with enhanced performance at low temperature (and mainly, which guarantee the leaktightness at -40 C). COGEMA LOGISTICS has qualified a new generation of fluorocarbon O-rings (TN trademark FLEX gaskets) which can be used in continuous service on a -47 C/+200 C temperature range. TN trademark FLEX gaskets will be implemented on new casks designs

    Full Text Available In the vast majority of cases, international abduction of a child determines almost per se litigations both at international and national level, namely an international litigation based on provisions of Hague Convention on the civil aspects of international child abduction and a domestic litigation aiming at establishing the domicile of the child in the state of destination and other different measures concerning the child which fall within the area of parental authority (joint or exclusive. The purpose of the article is to analyze the interaction between the international and the national case and how they influence each other from a double perspective (procedural and substantial, taking into account that the two litigations are generally pending at the same time. Even the mere coexistence of the two litigations gives rise to the question which one should have priority in solving. Therefore, the objectives of this study are, on the one hand, to examine the implications in the domestic litigation of the decision pronounced in the Hague litigation (international competence, suspension of the national case, elements which are covered by the res judicata principle, and on the other hand to identify how a national decision on domicile and parental authority may influence the solution in the Hague case.

    As regards the environmental protection, the A.C.R.O. maintained in 2001 its programs of surveillance around the main western nuclear installations of France. The radioecological surveillance of the site of Cogema La-Hague for the dismantling of the former pipe of release in sea was one of the key points of this action environmental surveillance. The two accidents of atmospheric release in may and october 2001 at Cogema La Hague have shown the interest of an association as A.C.R.O.. It is thank to the measure, by our laboratory, of repercussions on environment of these incidents that it has been possible to bring to light a dysfunction of the measurement system of the gaseous effluents released by the facility operator. To improve the public information, A.C.R.O. concerns its main efforts on the development of the consumer technical information available on-line via its web site and in its regular publication 'the nuclear chronicle'. Besides, the participation of the A.C.R.O. to the radioecology North Cotentin group (within the framework of the continuation of its mission) but also at various local commissions of information (C.L.I.) as well as at the superior council of the safety and nuclear information ( C.S.S.I.N.) stays an essential action. Concerning the environmental protection, the A.C.R.O. maintains its programs of surveillance around the nuclear facilities of La Hague and Chinon and continues the surveillance of the site of Cogema La hague as regards the new pipe of release in sea. Among the new commitments for 2000, the participation to the radioecology North Cotentin group in the framework of the continuation of its mission and the participation to the international intercomparison 'N.O.R.C.O. 2000' punctuated the year.

    Hebrard, L.; Savornin, J.

    1991-11-01

    In the rooms of plant UP3-A where there are conventional fire hazards, arrangements have been taken to provide fire protection using a deterministic approach: creation of fire zones, installation of fire detection and occasionally extinguishing systems. These measures are determined by comparing the fire load density in each room with threshold levels. In the rooms where there are process-related fire hazards liable to involve radioactive materials, the fire protection measures are generally reinforced, especially if the rooms contain solvents: installation of fixed fire extinguishing systems depending on the quantity of solvent and the radioactive inventory as well as outlet fire dampers operable at high temperatures. Simultaneously, probabilistic studies of certain cells have made it possible to confirm the validity of the solutions adopted. (author)

Since the 1980s, antiorgan trade initiatives have mainly involved the strengthening of legislative responses. Little attention however is given to nonlegislative responses by law enforcement authorities. The HOTT project is a European Union-funded research project titled “trafficking in human beings for the purpose of organ removal.” Its objectives are to increase knowledge, raise awareness, and improve the nonlegislative response to the crime. Its consortium organized a “Writers' Conference” in The Hague, The Netherlands at Europol's Headquarters where a group of 40 experts, consisting of transplant professionals, law enforcement officials, and policy makers, formulated recommendations to improve nonlegislative responses. These recommendations, presented hereafter, address the ethical and legal obligations of health care providers, the protection of persons trafficked for the purpose of organ removal, strengthening cross-border collaboration in criminal cases, and stimulating partnerships between transplant professionals and law enforcement. These recommendations offer ways in which transplant professionals can contribute to improving the nonlegislative response to trafficking in human beings for the purpose of organ removal.

    Over the years, the trade in human organs has become an object of international concern. Since the 1980s, antiorgan trade initiatives have mainly involved the strengthening of legislative responses. Little attention however is given to nonlegislative responses by law enforcement authorities.

    The Hague Protocol is used by professionals at the adult Emergency Departments (ED) in The Netherlands to detect child abuse based on three parental characteristics: (1) domestic violence, (2) substance abuse or (3) suicide attempt or self-harm. After detection, a referral is made to the Reporting Center for Child Abuse and Neglect (RCCAN). This study investigates whether implementing this Protocol will lead parents to avoid medical care. We compared the number of patients (for whom the Protocol applied) who attended the ED prior to implementation with those attending after implementation. We conducted telephone interviews (n = 14) with parents whose children were referred to the RCCAN to investigate their experience with the procedure. We found no decline in the number of patients, included in the Protocol, visiting the ED during the 4 year implementation period (2008-2011). Most parents (n = 10 of the 14 interviewed) were positive and stated that they would, if necessary, re-attend the ED with the same complaints in the future. ED nurses and doctors referring children based on parental characteristics do not have to fear losing these families as patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

  16. THE HAGUE PRINCIPLES ON CHOICE OF LAW IN INTERNATIONAL COMMERCIAL CONTRACTS

    Full Text Available This article is dedicated to the one of the most important questions of the International Commercial Law. As a rule, it is widely accepted that the principle of party autonomy has been adopted, in respect of contractual obligations, by practically all national legislations in their provisions for private international law. At the same time, the Principles are silent regarding the option to choose trade usages as lex causae of the contract, and understandably so, since, from a systematic viewpoint, they cannot form a comprehensive set of rules capable of resolving basic issues of contractual obligations. Author believes that the Principles do not add any significant new features to the legal systems that have already developed and adopted the principle of party autonomy, with the exception of the possible application of non-national law before state courts. As a result, there have been formulated several useful conclusions which can be used in the science of the International Commercial Law.PRINCIPIILE DE LA HAGA PRIVIND ALEGEREA LEGILOR ÎN CONTRACTELE COMERCIALE INTERNAŢIONALEAcest articol este consacrat unor dintre cele mai importante probleme ce fac parte din dreptul internaţional comercial. De regulă, principiul autonomiei părţilor în contract este recunoscut ca unul fundamental în dreptul inter­naţional. Totodată, principiile păstrează tăcerea în ceea ce ţine de opţiunea de a alege uzanţele lex causae ale contrac­tului; prin urmare, ele nu pot fi privite ca reguli comprehensive şi susceptibile de a soluţiona problemele principale ale obligaţiilor contractuale. Autorul este de părere că principiile nu conţin nimic nou pentru legislaţiile naţionale în vigoare, deoarece nu au dezvoltat şi nu au adoptat ceva necunoscut pentru principiul autonomiei care este prevăzut în toate legislaţiile, cu excepţia unei posibile aplicări a legii supra-naţionale în instanţele naţionale de judecată.

  18. Needs and opportunities of adequate interpretation of the Hague convention on the civil aspects of international child abduction in the case of domestic violence

    Directory of Open Access Journals (Sweden)

    Samardžić Sandra

    2013-01-01

    Full Text Available At the time when the Hague Convention on the Civil Aspects of International Child Abduction was passed, that was a very logical step and a goal that this Conventionis set before it, and that is prompt return of children wrongfully removed or retained children, was a necessary consequence of the circumstances of that time. Namely, in most cases, men, that is fathers, were those, who illegally took or kept the children. More than thirty years later, the situation in that field has changed in the sense that mothers are now abductors in most cases, mostly seeing that this is the only way to escape from the violence they, or their children, are facing with. In that sense, the question is whether the achievement of the objective of this Convention is still justified, that is would it be justified any other interpretation of the Convention in situations where the unlawful removal or retention of children is a result of domestic violence.

    2006-06-01

    As sediments of several lakes are contaminated by uranium mines which are located upstream, and which have been exploited in the past by the Cogema (now Areva NC), this company asked for an authorization to use an old pit in Bellezane to deposit clearing sludge from water processing plants and from the clearing of ponds. This document describes the different problems raised by this project. It outlines that the site is not waterproof and that its legal status is not correct. It also reports and comments the radiological contamination of waters and soils due to site effluents, the chemical contamination of waters, and the existence of solid radioactive wastes at the vicinity of this site

    In the frame of COGEMA actins to reduce the volume of the reprocessing waste, a new strategy of drumming and incinerating is going to start at LA HAGUE and MARCOULE, for the low level waste planned for surface storage. This strategy depends on the performance improvement of non destructive measurements systems used for the alpha waste evaluation. In this global, closer links between COGEMA, SGN, CEA and EURYSIS MESURE have taken place to define a program in order to obtain up to three years the required performances, using active methods with neutron generator. These developments and tests are carried out on the PROMETHEE R and D facility at CEA-CADARACHE. (authors) 3 refs.

    Regular maintenance of packagings used for the transport of spent fuel has been carried out in Europe for the past three years. The three companies involved in this kind of transport (Cogema, Nuclear Transport and Pacific Nuclear Transport) have agreed on a common policy for these operations and, in practice, perform the maintenance work at a special facility (AMEC) at the La Hague reprocessing plant in France. This facility was erected in 1983, and commissioned in January 1984. The paper deals with the typical maintenance operations at the AMEC facility, the principles of control applied during maintenance, maintenance experience and future development and prospects.

    1995-01-01

    With 53 nuclear power plants in operation at EDF and a fuel cycle with recycling policy of the valuable materials, COGEMA is faced with the transport of a wide range of radioactive materials. In this framework, the transport activity is a key link in closing the fuel cycle. COGEMA has developed a comprehensive Transport Organization System dealing with all the sectors of the fuel cycle. The paper will describe the status of transportation of spent fuel and HLW in France and the experience gathered. The Transport Organization System clearly defines the role of all actors where COGEMA, acting as the general coordinator, specifies the tasks to be performed and brings technical and commercial support to its various subcontractors: TRANSNUCLEAIRE, specialized in casks engineering and transport operations, supplies packaging and performs transport operations, LEMARECHAL and CELESTIN operate transport by truck in the Vicinity of the nuclear sites while French Railways are in charge of spent fuel transport by train. HLW issued from the French nuclear program is stored for 30 years in an intermediate storage installation located at the La Hague reprocessing plant. Ultimately, these canisters will be transported to the disposal site. COGEMA has set up a comprehensive transport organization covering all operational aspects including adapted procedures, maintenance programs and personnel qualification

    International Nuclear Information System (INIS)

    Blanchard, O.; Criqui, P.; Kitous, A.

    2002-01-01

    The main objective of this paper is to assess the Bonn-Marrakech agreement, in terms of abatement cost and emission trading as compared with the initial agreement reached in Kyoto (the Kyoto Protocol). Our reference case (the Initial Deal) does not include the use of sinks credits, as the Kyoto Protocol does not give explicit figures nor method to estimate them. In addition, two hypothetical situations are considered. The first describes the ''missed compromise'' that could have emerged among all Parties in November 2000 in The Hague. The second is a virtual case where the US is assumed to be part of the Bonn-Marrakech Agreement, along with all the other Parties. These two cases contribute to shed the light on the Bonn-Marrakech Agreement potential pitfalls. In the current situation, the US is out of the negotiation process and has no emission reduction commitment. Given the projections of carbon dioxide (CO 2 ) emissions used in this study, the Former Soviet Union countries (FSU) and the Eastern European Economies (EEE) that are part of the Annex B have potentially enough Hot Air to fulfill the overall commitment of the Annex B bubble, without any domestic abatement effort from the other Annex B countries. We show that in the theoretical case where no limit would be imposed on the selling of Hot Air, the permit price according to the POLES model would be zero as no market equilibrium could take place. This is why, next, we examine the economic impacts of restrictions to hot air trading, for FSU and EEE as well as for the other countries. We shed the light on the potential market power of the former countries that arises from the Bonn-Marrakech Agreement. (author)

  9. Vitrification of HLW in cold crucible melter

    International Nuclear Information System (INIS)

    Bordier, G.

    2005-01-01

    The performance of the vitrification process currently used in the La Hague commercial reprocessing plants has been continuously improved during more than ten years of operation. In parallel the CEA (French Atomic Energy Commission), COGEMA (Industrial Operator), and SGN (COGEMA's Engineering) have developed the cold crucible melter vitrification technology to obtain greater operating flexibility, increased plant availability and further reduction of secondary waste generated during operations. The cold crucible is a compact water-cooled melter in which the radioactive waste and the glass additives are melted by direct high frequency induction. The cooling of the melter produces a solidified glass layer that protects the melter's inner wall from corrosion. Because the heat is transferred directly to the melt, high operating temperatures can be achieved with no impact on the melter itself. COGEMA plans to implement the cold crucible technology to vitrify high level liquid waste from reprocessed spent U-Mo-Sn-Al fuel (used in gas cooled reactor). The cold crucible was selected for the vitrification of this particularly hard-to-process waste stream because it could not be reasonably processed in the standard hot induction melters currently used at the La Hague vitrification facilities: the waste has a high molybdenum content which makes it very corrosive and also requires a special high temperature glass formulation to obtain sufficiently high waste loading factors (12 % in molybdenum). A special glass formulation has been developed by the CEA and has been qualified through lab and pilot testing to meet standard waste acceptance criteria for final disposal of the U-Mo waste. The process and the associated technologies have been also qualified on a full-scale prototype at the CEA pilot facility in Marcoule. Engineering study has been integrated in parallel in order to take into account that the Cold Crucible should be installed remotely in one of the R7 vitrification

    The need to apply for burn-up credit arises with the increase of the initial enrichment of nuclear fuel. When burn-up credit is used in criticality safety studies, it is often necessary to confirm it by measurement. For the last 10 years, CANBERRA has manufactured the PYTHON system for such measurements. However, the method used in the PYTHON itself uses certain reactor data to arrive at burn-up estimates. Based on R and D led by CEA and COGEMA in the framework of burn-up measurement for burn-up credit and safeguards applications, CANBERRA is developing the next generation of burn-up measurement device. This new product, named SMOPY, is able to measure burn-up of any kind of irradiated fuel assembly with a combination of gamma spectrometry and passive neutron measurements. The measurement data is used as input to the CESAR depletion code, which has been developed and qualified by CEA and COGEMA for burn-up credit determinations. In this paper, we explain the complementary nature of the gamma and neutron measurements. In addition, we draw on our previous experience from PYTHON system and from COGEMA La Hague to show what types of evaluations are required to qualify the SMOPY system, to estimate its uncertainties, and to detect discrepancies in the fuel data given by the reactor plant to characterize the irradiated fuel assembly.

    2006-01-01

    In a multilateral agreement, the United States (US) and the Russian Federation agreed to reduce their respective weapons stockpiles by each country disposing of 34 tons of military origin plutonium. On behalf of the US government, the Department of Energy contracted with Duke, COGEMA, Stone and Webster (DCS) to design a Mixed Oxide Fuel Fabrication facility (MFFF) which would be built and operated at the DOE Savannah River Site near Aiken, South Carolina. This plant will transform the US excess weapons stockpile into MOX fuel, which will be used it in existing domestic commercial power reactors. The MFFF is based on a replication of AREVA existing facilities (La Hague for Pu polishing and Melox for MOX fabrication). In parallel with the design, construction and startup of the MFFF facility, DOE commissioned fabrication and irradiation of 4 lead test assemblies in one of the Mission Reactors to assist in obtaining NRC approval for MOX fuel loading in US NPPs prior to the production phase of the MFFF facility. This program was named 'EUROFAB', since fabrication had to be made in Europe because no facility implementing the MFFF technology was existing in the USA. The COGEMA Recycling Business unit transmitted a bid to DCS in April 2003, which proposed to perform Eurofab fabrication in its Cadarache (pellets and rods) and Melox (assembly mounting) facilities. In August 2003, the decision was made by DCS, on behalf of the DOE, to award the EUROFAB fabrication contract to COGEMA. (author)

  13. The potentialities of the complexation ultrafiltration technique for the decontamination of fission product contaminated aqueous effluents; Potentialites de la complexation - ultrafiltration a la decontamination d`effluents radioactifs en produits de fission

    Thibert, V

    1995-07-01

    Many nuclear researchers and industrial operators lay emphasis on improving the back end of the fuel cycle. A major problem concerns the liquid wastes generated by the reprocessing plant at La Hague, discharged into the sea after treatment in the Effluent Treatment Station (STE) (3), and which have become crucial matter. The activity of these wastes is well below the current legal limits, and is constantly decreasing these last years. To bring it close to zero, and ambitious goal, entails innovative new reprocessing techniques. We accordingly investigated the possibilities of complexation-ultrafiltration, a technique that uses water-soluble macromolecules to complex the target elements to be separated. We first achieved the strontium (II) separation with poly-acrylic and poly-sulfonic acids. The effects of pH and NaNO{sub 3} concentration influence on Sr (II) complexation were studied. The Sr (II) complexation and concentration phases, followed by cation de-complexation to recover the polymer, were also taken into account. This research, combined with a potentiometric study of the polymers, offered a close understanding of the chemical systems involved, and of the operating conditions and limits of complexation-ultrafiltration. The laboratory results were also validated on a tangential ultrafiltration pilot plant. We then used complexation-ultrafiltration to treat a real effluent generated bu La Hague`s STE 3 plant. This experiment demonstrated minimum 90 % decontamination of Sr (II) (with polyacrylate complexing agent), and also for {sup 134-137}Cs (with simple ultrafiltration). The use of two polyamides allowed partial decontamination of the effluent for {sup 60}Co and {sup 106}Ru. This work therefore offers a global approach to complexation-ultrafiltration, from laboratory to pilot scale, on real and simulated effluents. The future of this technique relies chiefly on the ability to solve the problem of polymer recovery. (Abstract Truncated)

  15. Combined evaluation. Plutonium transports in France. Problems of safety and reliability of transport container FS47

    International Nuclear Information System (INIS)

    Marignac, Y.; Coeytaux, X.; Large, J.H.

    2004-09-01

    This report concerns the safety and the protection of plutonium dioxide transported from Cogema La Hague to the mixed oxide fuel plant of Marcoule and Cadarache. The French approach of the transport safety is based on the combining of two essential principles: the first one affirms that the performances of the FS47 container in regard of containment (norms TS-R-1 from IAEA for the accidental conditions) is conceived to resist in any situation even terrorism or sabotage. In fact, the IAEA norm follows a probabilistic study without a voluntary attack such a terrorist one. The second principle rests on the ability to prevent the treat of terrorism acts, because of a secrecy policy on the plutonium transport. It appeared that the Green peace association has succeeded several times to know exactly the hours, the trips of the plutonium transport and this simple thing raises more questions than it solves.

    Anybody having concernment in nuclear industry and engineering, and particularly in the fuel reprocessing activities, will be deeply concerned by the emerging cooperation between VEBA and Cogema at Cap de la Hague, and by the statements that could be heard from leading politicians. It is true that the current political and regulatory situation really does not invite potential operators to engage in further construction of nuclear installations, but one must not forget that 40 p.c. of electricity supplies are generated by West German nuclear power stations. Abandoning nuclear power does not seem to be a good decision if one considers the still growing demand for energy in the world, and the effects of fossil fuel consumption on the global climate.

    This report concerns the safety and the protection of plutonium dioxide transported from Cogema La Hague to the mixed oxide fuel plant of Marcoule and Cadarache. The French approach of the transport safety is based on the combining of two essential principles: the first one affirms that the performances of the FS47 container in regard of containment (norms TS-R-1 from IAEA for the accidental conditions) is conceived to resist in any situation even terrorism or sabotage. In fact, the IAEA norm follows a probabilistic study without a voluntary attack such a terrorist one. The second principle rests on the ability to prevent the treat of terrorism acts, because of a secrecy policy on the plutonium transport. It appeared that the Green peace association has succeeded several times to know exactly the hours, the trips of the plutonium transport and this simple thing raises more questions than it solves.

    On April 30, 1998 just a few days before the PATRAM 1998 conference at Paris, the French Nuclear Installations Safety Directorate (DSIN now DGSNR) published a press release, that during the year before some 35% of the spent fuel transports to the reprocessing plant of COGEMA at La Hague have non-fixed surface contamination in excess of the regulatory standard. A few day in advance DSIN informed in French Ministries and the competent foreign authorities of the customer countries of COGEMA. The consequences of this publication were multi-fold and perceived by the public as an act negligence of the nuclear industry. Because of concerns about additional radiation exposure to the railway workers by the unions the French Railway company SNCF suspended all transports by May 6, 1998 until implementation of corrective measures. This decision of SNF interupted also the spent fuel transports from continental Europe to the reprocessing plant of BNFL at Sellafield all performed across France to the port of Dunkirk. Furthermore on May 25, 1998 the German Federal Ministry of Environment, Nature Protection and Nuclear Safety (BMU) imposed a transport ban for shipment of spent fuel from commercial power plants and for high active waste returned from La Hague to the Gorleben site. The conditions for resumption of these transports were outlined by NMU in a 10-point programme. In response to these publications on contamination findings competent German State and Federal Authorities commissioned investigations by independent experts dealing with the identification of the causes, the proposal of counter measures, the investigation of shortcomings in the transport system in general and recommendations for retification of it

  2. MOX fuel reprocessing and recycling

    This paper is devoted to the reprocessing of MOX fuel in UP2-800 plant at La Hague, and to the MOX successive reprocessing and recycling. 1. MOX fuel reprocessing. In a first step, the necessary modifications in UP2-800 to reprocess MOX fuel are set out. Early in the UP2-800 project, actions have been taken to reprocess MOX fuel without penalty. They consist in measures regarding: Dissolution; Radiological shieldings; Nuclear instrumentation; Criticality. 2. Mox successive reprocessing and recycling. The plutonium recycling in the LWR is now a reality and, as said before, the MOX fuel reprocessing is possible in UP2-800 plant at La Hague. The following actions in this field consist in verifying the MOX successive reprocessing and recycling possibilities. After irradiation, the fissile plutonium content of irradiated MOX fuel is decreased and, in this case, the re-use of plutonium in the LWR need an important increase of initial Pu enrichment inconsistent with the Safety reactor constraints. Cogema opted for reprocessing irradiated MOX fuel in dilution with the standard UO2 fuel in appropriate proportions (1 MOX for 4 UO2 fuel for instance) in order to save a fissile plutonium content compatible with MOX successive recycling (at least 3 recyclings) in LWR.

    La Hague facility, in France, is the spent fuel recycling plant wherein a part of the fuel coming from some of the French, German, Belgian, Swiss, Dutch and Japanese nuclear reactors is reprocessed before being recycled in order to separate certain radioactive elements. The facility has been successively handled by the CEA (1962-1978), Cogema (1978-2006), and AREVA NC (since 2006). La Hague facility is composed of 3 production units: The UP2-400 production unit started to be operated in 1966 for the reprocessing of UNGG metal fuel. In 1976, following the dropout of the graphite-gas technology by EDF, an HAO workshop to reprocess the fuel from the light water reactors is affiliated and then stopped in 2003. - UP2-400 is partially stopped in 2002 and then definitely the 1 January 2004 and is being dismantled - UP2-800, with the same capacity than UP3, started to be operated in 1994 and is still in operation. And UP3 - UP3 was implemented in 1990 with an annual reprocessing capacity of 800 tons of fuel and is still in operation The combined licensed capacity of UP2-800 and UP3 is 1,700 tons of used fuel.

    SGN has undertaken the development of a new equipment ''NYMPHEA'', specially fitted for the purification of the pool water in spent fuel storage facilities. Based on ion-exchange process, these immersed units are working with high flow rate and a small thickness of the resins bed. Cogema has selected these ionic ''NYMPHEA'' for installation in the new storage basins already built or in construction in the new french reprocessing plant UP3 in La Hague (France). Together with the necessary and complementary hot tests in CEA laboratories (CADARACHE), a basic research has been started in cooperation with the Chemical Engineering Science Laboratory (LSGC Nancy) and the results already achieved are presented in this paper. Since two years, the ''NYMPHEA'' are into operation at La Hague (pool C), fulfilling all the required performances. This new and promising concept could, in the future, be extended to other applications, for the treatment of low salt content solutions, in the nuclear waste processing field, as well as for various chemical separations

    In France, Sogefibre (Cogema subsidiary) has developed original containers adapted to the conditioning of LLW and ILW and assuring integrity of the waste form over long period of time. These containers have been designed according to the following criteria, derived from Andra's requirement for the surface disposal: Mechanical strength, resistance to microcracking, Radioactive containment and long life: 300 years minimum. Choice of formulation for the concrete as well as selection of raw materials have been optimised in this objective. Sizes and shapes of Fiber Reinforced Concrete Containers (FRCC) have been developed in relation with handling means of Cogema La Hague facilities for automatized operations. Experience gained after nearly 10 years and 40000 FRCC produced shows that choices have been right and properties of FRCC effectively useful. The paper also recalls mechanical and containment properties and the durability assessment recently updated thanks to results of computer modelling. Degradation phenomenon of the Blended Ternary Cement (clinker, slag, ash) used in FRCC is described and the model presented. (authors)

    The decision taken in early 1970s to base the French power policy on the use of pressurized water reactors also included the strategy for the back end of the nuclear fuel cycle based on reprocessing, waste conditioning for the final disposal in the most suitable form in terms of safety and plutonium recycling to fast breeder reactors. Twenty years have elapsed, and substantial development and investment have been made. New evidences have emerged especially regarding breeder development, and the initial choice has been proved to be sound. EDF and COGEMA, the French utility and fuel cycle companies, respectively, are working together in order to take the best advantage of past efforts. The good behavior of MOX fuel in EDF reactors and the excellent start of the UP3 reprocessing plant of La Hague, which was completed and commissioned in August, 1990, made EDF and COGEMA extremely confident for future decision. The French choice made in favor of fuel reprocessing the history of fuel reprocessing in France, the policy concerning the back end of nuclear fuel cycle of EDF, and the present consideration and circumstances on this matter are reported.

    This paper presents the experimental programmes conducted in France by the Commissariat a l'Energie Atomique (CEA) in order to validate spent fuel inventory calculations for core studies as well as fuel cycle studies. This large experimental programme was obtained in collaboration with our French partners, Electricite de France (EDF), FRAMATOME-ANP and COGEMA. The experimental data are based on chemical analysis measurements from fuel rod cuts irradiated in French reactors for PWR-UOx and MOx fuels, then dissolved in CEA laboratories, and from full assembly dissolutions at the COGEMA/La Hague reprocessing plants for UOx fuels. This enables us to cover a large range of UOx fuels with various enrichments in 235 U, 3.1% to 4.5%, associated with burnups from 10 GWd/t to 60 GWd/t. Recently, MOx fuels have also been investigated, with an initial Pu amount in the central zone of 5.6% and a maximum burnup of 45 GWd/t. Uranium, Plutonium, Americium, Curium isotopes and some fission products were analysed. Furthermore, Fission Products involved in Burn up Credit studies were measured. The experimental database contains also data for Boiling Water Reactor (BWR) with irradiated samples of BWR 9x9 and full BWR assemblies dissolutions. Furthermore some data exist for Fast Breeder Reactor (FBR) with small samples irradiated in the PHENIX reactor. An overview of ongoing programmes is also presented. (author)

    The progressive implementation of some key nuclear fuel cycle capecities in a country corresponds to a strategy for the acquisition of an independant energy source, France, Japan, and some European countries are engaged in such strategic programs. In France, COGEMA, the nuclear fuel company, has now completed the industrial demonstration of the closed fuel cycle. Its experience covers every step of the front-end and of the back-end: transportation of spent fuels, storage, reprocessing, wastes conditioning. The La Hague reprocessing plant smooth operation, as well as the large investment program under active progress can testify of full mastering of this industry. Together with other French and European companies, COGEMA is engaged in the recycling industry, both for uranium through conversion of uranyl nitrate for its further reeichment, and for plutonium through MOX fuel fabrication. Reprocessing and recycling offer the optimum solution for a complete, economic, safe and future-oriented fuel cycle, hence contributing to the necessary development of nuclear energy. (author)

    Since the beginning of the nineties, EDF (Electricite France) has been carrying out a policy towards increasing burn-up. As a consequence and to keep energetic performances of the MOX (Mixed OXide uranium and plutonium) fresh fuel assemblies at parity with UO2 fuel, the concentration in plutonium increased up to 7.1%, soon up to 8.65% and even more. To take into account the increased dose rate and the increased thermal power of these MOX fresh fuels in the transportation system, COGEMA LOGISTICS designed, manufactured and licensed the MX8 package to replace the previous packaging. Simultaneously new high-secured transport system was developed. Due to the capacity of the reactor pool, the spent fuel assemblies must be evacuated with a short cooling time and high residual power. Because of the neutron source of these future MOX spent fuel assemblies, the TNa12/2 packaging, which has been in operation since 1980's to transport UO2 or MOX spent fuel to COGEMA La Hague, from EDF, other European and Japanese NPP lacks flexibility. COGEMA LOGISTICS is designing a new cask (TN trademark 112) to transport the future EDF MOX spent fuel assemblies. The TN trademark 112 has to comply with the 1996 edition of the IAEA transport regulations and with the transport and handling equipment presently used for the transport of spent fuel in France. It can be loaded with 12 assemblies, either MOX or UO2. This paper gives a description of two packages belonging to the new generation: - one for fresh MOX fuel assemblies transportation, used on EDF's power plants for MOX reloads, - one for spent MOX fuel assemblies transportation, presently under development with a first transport planned for mid-2007.

    The group has evaluated and validated the list and quantities of radioelements release(source term) for each of the four nuclear installations of the North Cotentin since their beginning of operation (the reprocessing plant of Cogema la Hague, the Flamanville nuclear power plant, the Manche storage plant and the arsenal of the Cherbourg harbour). The gathering of data relative to radionuclides in environment of the north Cotentin has allowed from one hand the publication of samples inventory and types of radioactivity measurements and in an other hand an analysis of the results. The intercomparison of transfer models in environment and the confrontation of their results with the measures have been used for the doses calculations to the references groups and to the children troop from the Beaumont-Hague district. Finally, the elements necessary to the doses and risks estimation have been itemized and validated. One of the questions that stands out of these works is this one of the aims of the surveillance and measurements in environment according to the different organisms that realize them. It is important to make the distinction between the routine measurements ( to be sure of the correct operation of the facility and that the authorized release limits are well respected) and the measurements that allow to reconstitute the dose to population groups.

    Around nuclear installations of La Hague, it is principally cesium{sup 137} that is found. The concentration is a few becquerels by kilogram of dry matter and comes from the fallout of nuclear tests before Chernobylsk accident. An excess of cesium is visible in the Sainte-Helene river where the levels go over the usual levels of a factor 10 then, in the presence of others elements such cobalt 60 (Co{sup 60}) or ruthenium-rhodium 106 (RuRh{sup 106}), iodine 129 (I{sup 129}) is also found. These pollutants find their origin in the gaseous releases of reprocessing plants. Between Granville and Saint Valery-en-Caux, along 500 kilometers of coast, four radioelements are systematically detected: cobalt 60, iodine 129, cesium 137, americium 214. Near the reprocessing plant of La Hague, the artificial radioactivity level increases with the presence of ruthenium-rhodium 106. The radiological situation is near this one of previous semesters, we can speak of stationary state, which improved with the years. It emphasize that the impact of nuclear power plants releases near the coast is not discernible. (N.C.)

    The solvent, used in France in Purex reprocessing plants at La Hague is tributylphosphate (TBP) diluted to 30% with a mixture of branched alkanes, for which the main component is branched dodecane (70%). In order to minimize volumes of organic wastes, we have to maintain Purex solvent qualities and to get rid of degradation products. The subject of this memoir concerns among all the degradation products the heaviest molecules. The separation and the identification of these products have been carried out by preparative steric exclusion chromatography, followed by the analysis of the samples by various analytical methods. An inactive residue containing heavy degradation products was prepared according to the process used in the UP3 La Hague plant. The Analysis of this residue using steric exclusion chromatography and GPC/MS methods, shows the presence of three families of compounds heavier than TBP: the ``dimers of TBP`` (provided from the addition of two molecules of TBP), the ``TBP-alkanes`` (the main molecule is the result of the addition of dodecane with TBP), and ``the functionalized TBP`` (hydroxyled TBP, nitrous TBP, nitrated TBP). Plutonium (IV) retention tests were made on the various fractions generated by steric chromatography. They showed that ``the dimers of TBP`` and ``the functionalized TBP`` families are responsible for that retention. These results confirm the good efficiency of the solvent distillation system operated in UP3 plant which allow the elimination of heavy degradation products of the solvent with the residue and then restore excellent extracting properties for the recycled solvent.

    As the international utilities community enters an era marked by new patterns such as deregulation, industrial nuclear companies must offer a broad and attractive series of flexible services in order to match with the utilities needs. COGEMA Group has therefore developed a global industrial answer-thanks to various technological tools-covering reprocessing of spent nuclear fuel, treatment of waste, and recycling of reusable materials as well as a transportation system. According to this framework, spent fuel is first shipped from the nuclear power plant to the. La Hague reprocessing site. The La Hague site-1997 reprocessed spent fuel quantities exceed 11,100 tU-offers a technically mastered and economically proven solution for spent fuel reprocessing. Besides the acquired industrial maturity, specially in the waste treatment and conditioning area-i.e., vitrification of high level waste reached more than 5,500 canisters at beginning 1998-future improvements are being prepared steadily. For instance, the construction of a new workshop, known as the ACC, for medium activity materials (hulls, end-pieces, and technological waste) compaction will be a milestone in the waste management concept. Industrial recycling of reusable materials (uranium and plutonium) is also implemented at full-throttle. For instance, the MELOX manufacturing plant-whose production reached 102 tHM in 1997 thanks to evolutive processes such as AMIMAS-allows to feed with efficiency the European MOX loading program (28 reactors: 15 in France, 8 in Germany, 3 in Switzerland and 2 in Belgium). Last, a dedicated transport organization-through highly specialized subsidiaries such as TRANSNUCLEAIRE-gives this industrial and technical scheme its consistency as shown by the successful return of vitrified residue to Japan. The development of new transport casks for instance MOX transport casks called the MX family-and the implementation of new techniques, like satellite tracking of trucks..., will give

  10. Risk perception and risk communication: lessons learned

    Industry can master risks but it cannot master the representations people have of these risks. This is why distortions may occur, as the public perceives risks where they are not, or in a totally deformed way. To deal with this type of situation which is dangerous in the long run, both for society and industry, it is necessary to study in detail where and how the difference between real risks and perceived risks is introduced. It then becomes possible to determine what means of action are available to manage the representations and the perceptions of risks. We shall mention two rather different examples of type of direct contact with the industrial reality; in France, we have determined policy of visits of nuclear sites (more than 10 000 people visit Cogema- la Hague site yearly), mainly addressed to school children and people living in the vicinity of the site. During these visits there is of course no question of explaining the detailed operation of the facility or the risks it generates. The purpose is to make the representation of the nuclear industry just as familiar as the representation of another large-scale technology tool: trains, dams,. In a different manner, missions are organised by Cogema - B.N.F.L.- O.R.C. (Overseas reprocessing Committee) to de dramatize the transport of high level vitrified wastes from Europe to Japan. these missions travel through those countries the ship come close to. Here, again, although the target is more the relays of opinion, the effective presence of specialized transport ship is a crucial element in putting a halt to phantasmic representations, as they are born from the remoteness of the object.

    As over the years, the nuclear industry worldwide was developing and building a clean, efficient and safe energy supply, it also built along the essential link for any global industry, transportation. The early approach at IAEA of creating international recommendations that then would be integrated into national laws came as a blessing to the structuration of transport This enabled a clear, recognized safety regime that has a proven world track record of outstanding safety. It also gave us a common language, and one may say that within the nuclear community, there is indeed a nuclear transport community. Because of steady and large flows of material for the nuclear cycles, countries where reprocessing of spent fuel takes place had to implement early on large transport structures and organizations. In most countries where reprocessing is not yet the main path for spent fuel management, like in the USA and in Canada, large scale transport for the back-end is still at the inception stage. Today the industry must demonstrate that waste is properly managed and that the peaceful use of nuclear energy delivers indeed the best economic and environmental value. Transport has to answer a part of this challenge if the industry is to grow further. The paper will illustrate how the current continental Europe systems of transport progressively evolved so as to make daily deliveries of spent nuclear fuel to the COGEMA La Hague reprocessing plant a strong, dependable and effective system. It also shows that this experience is in the background of a major study ordered by Ontario Power Generation from COGEMA Logistics, as a contribution to the work of the trust now examining approaches to long-term management of spent fuel in Canada.

    In France, the nuclear waste issued from the industrial reprocessing of spent nuclear fuels (by the PUREX process) are currently vitrified at the La Hague plant, waiting for a final disposal in a deep geological repository. The law voted in June 2006 on the management of highly active nuclear waste plans to look for solutions enabling the separation and transmutation of long-lived radionuclides so as to reduce the quantity and noxiousness of the final nuclear waste. To address this issue, the CEA investigates and elaborates advanced separation processes based on specially designed complexing or extracting molecules to selectively extract minor actinides from PUREX raffinates containing fission products like lanthanides, which are neutron scavengers. BTP or bis-triazinyl-pyridines have been extensively studied at the CEA (and in Europe) for actinides(III)/lanthanides(III) separation. They complex actinides(III) selectively. However, they are sensitive to degradation by hydrolysis and radiolysis. Besides, their separation mechanisms are not well understood, especially the influence of their substituting groups on their complexing and extracting properties. The first part of work reports the syntheses of various BTP and BTBP molecules, differently substituted, as well as a new family of poly-aromatic nitrogen-contained ligands: BPBT, presenting a pyridine/triazine sequence that has never been reported in the literature. The second part is devoted to the physico-chemistry studies of the synthesized molecules, such as the determination of their protonation and complexation constants to describe the influence of different substituting groups. Finally, the last part outlines solvent extraction studies by using these ligands either like extractants or like complexants.

Los actos de violencia, que se dan de forma bidireccional en la pareja, tienen su origen en los procesos de socialización, tanto por la práctica de malos tratos, como por la transmisión de valores que se concretan en actitudes justificadoras de la violencia. El equilibrio de poder entre los miembros de la pareja, la modificación de las actitudes, la mejora de las habilidades para resolver conflictos y la reducción de los elementos estresantes pueden contribuir notablemente a reducir los niveles de violencia conyugal.

    2002-01-01

    The supervision of industry and defence on French radiation protection and withhold information during public inquiries in nuclear facilities questions make organizations anxious. Two examples are given: the first one concerns the file presented by EDF in november 1998 to get new release authorizations on the st Alban site, some information about tritium lacked( thirty analysis on tritium lacked for impact studies) and tritium is an element that represents 99.99% of released radioactivity by the nuclear power plant in the Rhone river. The Crirad organization asked for the public inquiry canceling. In vain. The second example is relative to the reprocessing plant of La Hague; at the end of 1999 the Cogema wished to extend its fuel range and increase its treatment capacity then it dropped off a file of public inquiry that did not take into account the increase of radioactive releases. The operator did not want the file to wear on this aspect, it won one's case. (N.C.)

    BNFL International Transport's operational experience includes shipping 6000te of spent fuel from Japan to Sellafield, through its dedicated terminal at Barrow, and to Cogema La Hague. This fuel was shipped under the PNTL (Pacific Nuclear Transport Ltd) banner for which BNFL is responsible. PNTL owned and operated a fleet of 5 ships for Japanese business and a fleet of 80 wet and 58 dry flasks, for the transport of Light Water Reactor (LWR) spent fuel, from both Pressurised Water Reactors (PWR) and Boiling Water Reactors (BWR). ''Wet'' or ''dry'' flask is the common terminology used to distinguish between spent fuel flasks transporting fuel where the fuel is immersed in water, or spent fuel flasks that have been drained of water and dried. This paper concentrates on the wet type of flask utilised to transport fuel to Sellafield, that is the Excellox type (including similar type NTL derivatives). It aims to provide a summary of operational experience during handling at power stations, shipment, unloading at reprocessors and from scheduled maintenance

    1999-01-01

    The review presented is an excerpt from an expert opinion written by the author in December last year, in response to changes in nuclear energy policy announced by the new German government. The reprocessing of spent nuclear fuels from German power reactors in the reprocessing facilities of France (La Hague) and the UK (Sellafield) is not only based on contracts concluded by the German electric utilities and the French COGEMA or the British BNFL, but has been agreed as well by an exchange of diplomatic notes between the French Ministry of Foreign Affairs and the German ambassador in Paris, the German Foreign Ministry and the French ambassador as well as the British ambassador in Bonn. The article therefore first examines from the angle of international law the legal obligations binding the states involved, and Germany in particular, in matters of spent fuel reprocessing contracts. The next question arising in this context and discussed by the article is that of whether and how much indemnification can be demanded by the reprocessing companies, or their governments, resp., if Germany should discontinue spent fuel reprocessing and thus might be made liable for breach of the bilateral agreements.

  8. Cost estimation of the decommissioning of nuclear fuel cycle plants

    Barbe, A.; Pech, R.

    1991-01-01

    Most studies conducted to date on the cost of decommissioning nuclear facilities pertain to reactors. Few such studies have been performed on the cost of decommissioning nuclear fuel cycle plants, particularly spent fuel reprocessing plants. Present operators of these plants nevertheless need to assess such costs, at least in order to include the related expenses in their short-, medium- or long-term projections. They also need to determine now, for example, suitable production costs that the plant owners will have to propose to their customers. Unlike nuclear reactors for which a series effect is involved (PWRs, BWRs, etc.) and where radioactivity is relatively concentrated, industrial-scale reprocessing plants are large, complex installations for which decommissioning is a long and costly operation that requires a special approach. Faced with this problem, Cogema, the owner and operator of the La Hague and Marcoule reprocessing plants in France, called on SGN to assess the total decommissioning costs for its plants. This assessment led SGN to development by SGN engineers of a novel methodology and a computerized calculation model described below. The resulting methodology and model are applicable to other complex nuclear facilities besides reprocessing plants, such as laboratories and nuclear auxiliaries of reactor cores. (author)

    COGEMA is operating large size purifying and conditioning plutonium facilities at LA HAGUE and MOX fuels fabrication plant at Marcoule. A high safety standard is recognised for these facilities. It is mainly based on : - prevention of spreading of radioactive materials to workers and environment by physical barriers ensuring static containment and by a cascade of pressure differentials ensuring dynamic containment, - radiation shielding and remote controlled processes ensuring very low dose to workers, - prevention of criticality accident by criticality control methods and double contingency principle, - prevention of fire risks by control of ignition sources, adequate management of combustible materials, physical separation between zones where there is a risk of fire and the remainder of the facility. The facilities are operated while respecting safety requirements as described in the General Operating Rules. The equipment involved in safety functions are monitored and periodically checked. Continuous improvement by incorporation of feed back of safety experience results in: - effective decrease of exposure to operating staff; - reduction of solid waste, liquid and gaseous effluents; - no significant incident recorded.

    In the La Hague COGEMA's plant area, nuclear residue isolated by reprocessing are transported by means of specific transfer shuttles between the different processing and/or conditioning facilities and the storage ones. These shuttles are designed by reference to the applicable dose equivalent rate (DER) limits for transport on the site and the thermal behavior limitations of certain mechanical components which guarantee the containment of the transported waste. This paper describes and example of a study conducted on a transfer shuttle for vitrified residue canisters. Concerning the control of risks associated with external exposure and with heat releases, these were handled by the 'Shielding-Criticality-Dispersion' and 'process Modelling and Simulation' Sections of the Technical Division of SGN. The dose profiles around the shuttle, as a function of the shielding heterogeneities and possible radiation leakage, as well as the thermal fields within the shuttle, were calculated using 3D models. These design studies ultimately helped to select and validate the optimal solutions. (authors)

    The accurate measurement of heavy nuclide masses and activities in radioactive wastes drums is an important part of waste management. The Active/Passive non destructive assay of radioactive waste drums using a 14 MeV neutron generator is particularly interesting for alpha low level measurements or for gamma irradiating wastes.

    1995-01-01

    The final safe disposal of radwaste, in France and elsewhere, entails, for liquid effluents, their conversion to a stable solid form, hence implying their conditioning. The production of conditioned waste with the requisite quality, traceability of the characteristics of the packages produced, and safe operation of the conditioning processes, implies at least the accurate knowledge of the chemical and radiochemical properties of the effluents concerned. The problem in sampling the normally charged effluents is aggravated for effluents that have been stored for several years in very large tanks, without stirring and retrieval systems. In 1992, SGN was asked by Cogema to study the retrieval and conditioning of LL/ML chemical sludge and spent ion-exchange resins produced in the operation of the UP2 400 plant at La Hague, and stored temporarily in rectangular silos and tanks. The sampling aspect was crucial for validating the inventories, identifying the problems liable to arise in the aging of the effluents, dimensioning the retrieval systems and checking the transferability and compatibility with the downstream conditioning process. Two innovative self-contained systems were developed and built for sampling operations, positioned above the tanks concerned. Both systems have been operated in active conditions and have proved totally satisfactory for taking representative samples. Today SGN can propose industrially proven overall solutions, adaptable to the various constraints of many spent fuel cycle operators

  14. Specific application of burnup credit for MOX PWR fuels in the rotary dissolver

    In prospect of a Mixed OXide spent fuels processing in the rotary dissolver in COGEMA/La Hague plant, it is interesting to quantify the criticality-safety margins from the burnup credit. Using the current production computer codes and considering a minimal fuel irradiation of 3 200 megawatt-day per ton, this paper shows the impact of burnup credit on industrial parameters such as the permissible concentration in the dissolution solution or the permissible oxide mass in the rotary dissolver. Moreover, the burnup credit is broken down into five sequences in order to quantify the contribution of fissile nuclides decrease and of minor actinides and fission products formation. The implementation of the burnup credit in the criticality-safety analysis of the rotary dissolver may lead to workable industrial conditions for the particular MOX fuel studied. It can eventually be noticed that minor actinides contribution is negligible and that considering only the six major fission products is sufficient, owing to the weak fuel irradiation contemplated.

    For more than 30 years, Transnucleaire has been performing safely a large number of national and international transports of radioactive material. Transnucleaire has also designed and supplied numerous packagings for all types of nuclear fuel cycle radioactive materials: for front-end and back-end products and for power and research reactors. Since the last meeting held in Bruges, Transnucleaire has been continuously involved in transportation activities for fresh and irradiated materials for research reactors. We are pleased to take the opportunity in this meeting to share with reactor operators, official bodies and other partners, the on-going developments in transportation and associated services. Special attention will be paid to the starting of transports of MTR spent fuel elements to the La Hague reprocessing plant where COGEMA offers reprocessing services on a long-term basis to reactors operators. Detailed information is provided on regulatory issues, which may affect transport activities: evolution of the regulations, real experiences of recent transportation and development of new packaging designs. Options and solutions will be proposed by Transnucleaire to improve the situation for continuation of national and international transports at an acceptable price whilst maintaining an ultimate level of safety (author)

  16. Review of annual radioecological studies carried out since 1991 in the French nuclear power plants environment

    Duffa, C.; Gontier, G.; Renaud, P.

    2004-01-01

    Since 1991, the IRSN carries out annual radioecological studies in the environment of the French Nuclear Power Plants. More than 5,000 samples, collected in terrestrial and aquatic ecosystems around the 20 studied plants, have been analysed by low-level gamma spectrometry. This paper presents the main goals and methods for such studies, and the lessons learnt from 11 years results. The French NPP routine atmospheric releases do not lead to detectable radioactive inputs into their surroundings. For this reason, IRSN decided to reduce the number of analysis concerning terrestrial samples since 2000. On the other hand, NPP liquid discharges into rivers are responsible for the presence of low 60 Co, 58 Co, 110m Ag and 54 Mn activities and significant difference in 137 Cs/ 134 Cs activity ratios measured in aquatic compartments. Radioactive discharges of artificial gamma emitters are also detectable in the Channel marine environment around NPP. Nevertheless, this influence is often concealed by radionuclides released by COGEMA-La Hague nuclear reprocessing plant. Beyond important evaluations concerning the presence of artificial radionuclides in NPP's environment, studies conducted since 1991 give us an important database that can be used for a better knowledge of transfers and distribution of radioactivity through the environment.

    A joint COGEMA/CEA action aims at evaluating the conditions allowing the extension beyond 50 years of the exploitation of the E/EV/SE vitrified wastes storage facility of the UP3 factory of La Hague (France). The approach considered consists in analysing the technical and administrative aspects of the facility in order to determine the changes to be implemented for its qualification as very long storage facility. Three target characteristics have been identified as priorities for this analysis: safety, civil engineering, and cooling ventilation of wells, and thus three working groups have been created. According to works carried out, facilities like the E/EV/SE one are designed in such a way that their durability can reach the century scale: the robustness of the cooling process, the passiveness of most equipments and the limitation of components functions are the main strong points. Service life limitations come mainly from the thermal evolution of waste packages and the aging of components under the climate conditions: risk of atmospheric corrosion of the bottom part of wells under the effect of water condensation, and risk of corrosion of concrete reinforcements. Suggestions of improvement of the quantification and understanding of phenomena influencing the lifetime limitation are made, and some possible technical solutions are proposed. (J.S.)

  18. Reprocessing-conditioning-recycling: A competitive industry at the service of the utilities

    In order to answer to the future energy needs, the countries who have chosen nuclear power as a main energy source, have also opted for an optimisation of their policy through the Reprocessing-Conditioning-Recycling (RCR) strategy. The RCR industry is today totally mature and comprehensive thanks to proven industrial means for reprocessing through the UP3 and UP2-800 plants of the la Hague site and for Mixed Oxide fuel (Mox) supply. The optimisation of the RCR industry following the chromological logic of the fuel cycle development, has now focused on two main items: The fabrication of the Mox fuel and the management of the residues with a notably drastic reduction of the total volume of residues. From 1990 to 1994, several studies of the total fuel cycle cost have been carried out; German studies generally concluded to a potential advantage of the Direct Disposal option compared to the RCR strategy. But a 1996 Cogema-study, integrating the most recent data and based on a cost model of the complete fuel cycle, has shown (like the 1994 OECD study) very similar costs between the two options. Thanks to the industry optimisation, the RCR strategy has allowed to decrease the fuel cycle cost to a very low level of 1,5 Pf/kWh. The RCR strategy is economically competitive and less sensitive to price variations. Furthermore, it is immediately available for the utilities who consequently take advantage of a global service with firm prices. (orig.) [de

    Following the formation of United Reprocessors (U.R.G.) in 1976 by British Nuclear Fuels Limited (B.N.F.L.) in the United Kingdom, the Commissariat a l'Energie Atomique (C.E.A.) in France and K.E.W.A. Kernbrennstoff-Wiederaufarbeitungs-Gesellschaft MBH (K.E.W.A.) in Germany, collaboration is now well established for the marketing of their reprocessing services for irradiated oxide fuel from thermal reactors. In addition collaboration in the continued evolution of the technology has progressed and an extensive research and development programme has been established, the results of which are exchanged between the shareholders. During 1976 the U.K. Government has given approval to B.N.F.L. to sign further contracts with foreign customers, subject to certain conditions. In France, the fuel cycle activities of the C.E.A. have been vested in a new company (Compagnie Generale Des Matieres Nucleaires (C.O.G.E.M.A.)) and their La Hague plant has commenced reprocessing operations on irradiated oxide fuel. In Germany, an agreement has been signed between K.E.W.A. and P.W.K. for the pre-project study for the proposed German plant. Against this background this paper reviews the present status of reprocessing by the shareholders of U.R.G. and the prospects for reprocessing

    1998-01-01

    In continuity of the CEA HLW vitrification process experienced for more than 20 years in industrial operations in Cogema reprocessing plants (Marcoule and La Hague), CEA has developed an advanced extended performance cold crucible glass melter to address a wider range of waste like LLW, ILW and in particular waste with very corrosive species or requiring glass with higher elaboration temperature. In the cold crucible melter the bath of molten glass is directly heated by induction while the walls are cooled in order to freeze a protective glass layer. This technology subsequently allows high glass throughput while keeping the flexibility, the maintainability and low secondary waste generation related to a small metallic melter. Its recent use in the glass industry and the thousands of hours of pilot tests performed on inactive surrogates have demonstrated the maturity of this technology and its flexibility of use for processing most of the waste generated at nuclear facilities. SGN has therefore proposed this technology in Italy and Korea and in USA in the frame of the Hanford Privatization phase 1 A feasibility study. Main features of this study but also tests results with Hanford surrogates and active samples are discussed. (author)

    Full Text Available En este artículo se presentan lo que se considera la última fase de la erradicación de la poliomielitis en España, la cual llevó 25 años, duran- te el período 1963-88, a raiz del brusco descenso que produjo en la incidencia de la enfermedad la introducción de la vacuna Sabin con cepas atenuadas en el año 1963. Ello debería haber conducido a la desaparición de la enfermedad en un corto período de tiempo, aunque no fue así a causa de la disminución de la vacunación y la vigilancia epidemiológica, que no se retomaron con seriedad hasta 1976. El último caso autóctono se produjo en 1988. Tras asumir Rafael Nájera la dirección del centro Nacional de Microbiología, Virología e Inmunología Sanitarias, el primer objetivo de su equipo fue la erradicación de la poliomielitis de nuestro país, introduciendo los criterios de clasificación de la OMS y los estudios de caracterización intertípica de las cepas aisladas de virus.

  5. La igualdad de oportunidades en la escuela de la diversidad

    Full Text Available La sociedad actual ha vivido en estos últimos años una acumulación de cambios en los valores, actitudes y prácticas, que se reflejan en los planteamientos de la educación y en la realidad de la escuela. Uno de estos cambios se refiere al reconocimiento de la diversidad del alumnado, que obliga a la búsqueda de alternativas didácticas en la educación y en la práctica de la escuela: desde el reconocimiento explícito del derecho de todos a la educación y de que ésta se desarrolle atendiendo a la igualdad de oportunidades; donde la diversidad sea un valor enriquecedor y positivo para todos. Estas alternativas se fundamentan en el paso de un modelo de intervención compensatoria a introducir prácticas coherentes con la inclusión educativa, que se fundamenta en la implantación de un currículum comprensivo común y a la determinación de apoyos normalizados para alcanzar una real integración de todos los alumnos.

En la era digital la  interactividad ha abierto a muchos artistas y técnicos la posibilidad de realizar obras en las que la interactividad constituye el componente fundamental de la obra. Los principios que determinan este tipo de relación entre artista y espectador tienen que ver con las posibilidades tecnológicas pero también con la forma en que contemplamos la obra de arte.

    Full Text Available La violencia escolar se ha convertido en foco de atención no sólo de investigadores, sino de todos aquellos involucrados en el quehacer educativo y de la sociedad en general. Lo anterior debido a la creciente ola de violencia que se presenta en los distintos ámbitos de la actividad humana. El punto de interés del presente estudio tiene como objetivo la descripción de la violencia narrada por los mismos alumnos de los distintos niveles educativos. Para ello, se utilizó la técnica de grupo de discusión para rescatar los discursos individuales y colectivos de 37 estudiantes (16 mujeres y 21 varones entre 3 y 22 años provenientes de 27 escuelas de diversos niveles educativos de la ciudad de Xalapa, México. El análisis cualitativo de los datos se realizó mediante el programa ATLAS.ti. Los resultados indicaron la existencia de violencia en todos los niveles escolares estudiados. Sin embargo, las formas, tipos, lugares y la dirección de la violencia, así como el género en la expresión de la violencia cambió desde niños preescolares hasta jóvenes universitarios. Los resultados señalaron que con respecto a la dirección de la violencia, el maltrato entre iguales se presentó con mayor frecuencia al igual que la violencia de tipo psicológico. Respecto a las formas predominaron los golpes y las agresiones verbales con manifestación principalmente en el baño y los espacios abiertos de la escuela. Los datos encontrados en cada nivel escolar permiten concluir que el comportamiento violento se encuentra relacionado con la edad y que junto con la influencia cultural determinan su expresión.

    Full Text Available Es tiempo para reflexionar sobre las consecuencias que, para el pensamiento historiográfico, significan los nuevos modos de representación simbólica del tiempo relacionados con los cambios materiales e intelectuales de fin de siglo. Los viejos paradigmas positivistas y estructuralistas, de naturaleza moderna (racionalidad, explicación, objetividad, linealidad, teleología, necesidad, normativismo, universalidad, van dando paso a nuevos modelos de construcción del relato histórico según patrones fenomenológico-hermenéuticos (interpretación, ruptura, azar, relativismo, localismo. La crisis de la idea ilustrada de progreso está impulsando una nueva concepción "anti-histórica», en la medida en que la historia se convierte en espacio temporal pluridimensional, ambiguo, efímero, atemporal. El nuevo tiempo de la historia deja de ser proyectivo. ¿No estaremos ante la elaboración simbólica de una experiencia vital verdaderamente ahistóríca? ¿Qué puede representar ello en lo que respecta al cambio social? ¿Paralización? ¿Congelación y perpetuación del nuevo orden? ¿Es posible ya la anticipación del futuro desde un presente desligado de toda secuencia racionalmente inteligible para el sujeto?.It's time to think about the consequences which, to the historiographic though, mean the new ways of symbolic representation of time related to the material and intelectual changes at the end of this century. The old positivist and structuralist paradigms, of modern nature (rationality, explanation, objectivity, lineality, teleology, necessity, universality, are giving way to the new models of construction of the historical discourse following phenomenological-hermeneutical patterns (interpretation, rupture, chance, relativism, localism. The crisis of the enlightened idea of progress is urging a new non-historie conception, as for as history turns inte temporal space which is also multi-dimensional, ambiguous, ephemeral, nontemporal.

    2015-01-01

    Full Text Available Inscrito dentro de la sociología de la cultura, el presente trabajo constituye un análisis crítico de la psicología positiva, que se toma como ejemplo paradigmático del actual imperativo cultural de la felicidad. El contexto teórico es el de la individualización contemporánea y la cultura psicoterapéutica, que preconizan una concepción del yo reflexiva y autoconstituida, al margen de una comprensión moral y social de la identidad personal. He estudiado las técnicas para lograr la “positividad”, constituyendo su análisis crítico el grueso de este trabajo. Asimismo he analizado los valores, los lenguajes morales de la psicología positiva y las tensiones de los diversos repertorios de significado. He tratado los textos que se encuentran a medio camino entre la psicología científica y la popular, que sirven como ejemplos de la literatura de consejos, que contiene normas explícitas de conducta y alude a las buenas y malas emociones, con la intención de definir un modelo de identidad personal concreto.

  1. La escritura intermedial en la escena actual

    Full Text Available Las escrituras artísticas actuales integran, en el marco determinado por las realidades intermediales de la escena tecnológica, el concepto de diseño como manipulación perceptiva del espacio, lo que constituye uno de los instrumentos determinantes en la puesta en marcha de un cuadro compositivo de resonancias transformacionales. Podríamos en este sentido hablar de una nueva ecología artística y en especial, teatral. En la renovación del pensamiento teatral actualizado, fuertemente influenciado por la estructura discursiva cinematográfica y por los universos sensoriales de la cultura tecnológica de la imagen y del sonido, está la base de la multiplicación diegética, de la superposición, de la fragmentación de los discursos y de la praxis inter-relacional en la que radica, en gran medida, la potencia intermedial de la escena actual.

    2014-12-01

    Full Text Available Este trabajo propone analizar la evolución de la vivienda como respuesta ante emergencias desde principios del siglo XX hasta nuestros días. La secuencia de casos a analizar no sigue una cronología estricta sino que se organiza en función de un creciente grado de complejidad. Comienza con los aportes fundamentales de la vivienda mínima del movimiento moderno, con un fuerte acento en lo tecnológico, para ir profundizando, mientras avanzamos en el siglo, en los aspectos sociales de la arquitectura. Sin intentar oponer lo tecnológico y lo social, la estructura propuesta expresa un enriquecimiento de la cuestión técnica conforme se van ampliando sus objetivos sociales. Mientras los requerimientos tecnológicos como la inmediatez y la masividad de la respuesta, permanecen a lo largo del tiempo, la vivienda ante emergencias puede plantearse objetivos sociales cada vez más profundos. Los casos fueron elegidos a partir de autores renombrados de la Historia de la Arquitectura partiendo de ejemplos cercanos a la génesis del movimiento moderno para acercarnos cada vez más hacia el contexto actual de Latinoamérica. Se logra así un barrido geográfco pero principalmente cultural: desde las fuentes de la modernidad, bajo el paradigma sólido de la industrialización, hasta la inestabilidad de la ciudad posindustrial latinoamericana

En el artículo se discute el origen del sistema, partiendo de la idea de que la más primitiva escritura paleohispánica, todavía no identificada, se originó como adaptación de la escritura fenicia que era un silabario con valores vocálicos no explícitos. A la vista de la escritura del SO, que parece ser un alfabeto redundante (con signos distintos pata una misma oclusiva en distintas posiciones antevocálicas, se defiende la posibilidad de que el excesivamente rico inventario fenicio de oclusivas diese lugar a la aparición del alfabeto redundante y éste a la del semisilabario.ABSTRACT: Early Hispanic writings are anomalous, part syllabic, part alphabetical systems, and of general interess from the point of view of the history of writing. This article discuss the origin of the system as adaptation of the Phoenician consonatal syllabary. There is evidence in the writing from the South-West for an alphabet with redundancy, born from the rich Phoenician inventory of stops; the syllabic component of the other Hispanic writings was a development of this redundancy.

    Full Text Available Las relaciones sociales responden a la pregunta de cómo se sitúan los hombres en el proceso de la producción si atendemos a quién o quiénes son los propietarios o los poseedores de los útiles. Para el paleolítico —inferior, medio y superior— y aún después, claramente se ve que no se puede hablar de clasese sociales si éstas se definen a partir del concepto de propiedad o de posesión. ¿Qué se entiende por propiedad en la sociedad primitiva? Podríamos definir la propiedad como una posesión reconocida por los miembros de la sociedad, garantizada por las normas de vida de la comunidad, admitidas por tal sociedad y protegida por la costumbre o por la ley. Esta definición para época paleolítica no sirve. Decir que propiedad es una posesión es no intentar resolver el problema, porque tendríamos que preguntarnos inmediatamente qué se entiende por posesión en una época que grosso modo abarca desde 5,5 millones de años al 9000 a. n. e. Si examinamos la definición donde se habla de que la posesión está garantizada por las normas de vida en común y protegida por la costumbre o por la ley ¿cómo podemos investigar la norma, la costumbre o la ley durante el paleolítico inferior, medio o superior?

La conjunción de ambas formas de volatilidad, la financiera y la real, ha acentuado la vulnerabilidad de las personas más débiles.

Se consideran diferentes dimensiones de la globalización (económica, tecnológica, cultural y política y se discuten sus consecuencias sobre la salud en términos epidemiológicos, éticos, sanitarios, ambientales y en relación con la distribución del poder y la equidad. Se analizan datos que evidencian la globalización de los riesgos y las enfermedades, atribuibles al actual modelo de relaciones internacionales y a la movilidad entre países. En el artículo se defiende la propuesta de globalizar la salud, integrando conceptos renovados y adelantos en las ciencias afines a la salud pública con nuevas estrategias políticas, sociales y organizativas de la práctica sanitaria. Finalmente, se reconocen las oportunidades que nos brinda la globalización, desde mediados del siglo pasado, para redefinir la gobernabilidad mundial y desarrollar movimientos locales, basados en la solidaridad y en una nueva concepción política que favorezcan la universalización de la salud.

    Un bajo porcentaje cumplió con todas las normas del Ministerio de Salud y se trata de Plantas que reciben y procesan leches de hatos, en donde las instalaciones, la alimentación, la sanidad, la calidad genética y la producción
    están a la altura de los países industrializados.

    II. El consumo de leche en el país es bajo y no alcanza los niveles recomendados por los organismos de Salud.

    III. La leche es susceptible de contaminarse por la ignorancia, negligencia, prácticas fraudulentas o el empleo de técnicas inadecuadas en su procesamiento, transporte, conservación, comercialización e industrialización.

    IV. Se plantean interrogantes sobre la presencia en la leche, de residuos de antibióticos, pesticidas, hormonas, tranquilizantes, compuestos inorgánicos y la forma como puedan estar afectando la salud humana.

    V. La contaminación cada vez mayor del ambiente, el rápido transporte de los alimentos; sus técnicas de elaboración, los cambios en los hábitos alimentarios, han aumentado los peligros de enfermedades que se pueden trasmitir por los alimentos.

    VI. La Salud depende en buena parte de la alimentación y si los alimentos de origen animal son medios de propagación de agentes patógenos y tóxicos, la respuesta a este interrogante no es solamente cómo aumentar la producción, sino cómo alimentar una población afectada por pobreza y desnutrición con alimentos sanos.

  9. French industrial capabilities for the back-end operations

    International Nuclear Information System (INIS)

    Caspar, Gilles A.

    1988-01-01

    Based upon processes initiated by the Commissariat a l'Energie Atomique and its industrial partners, France has been elaborating for about thirty years a steady and consistent programme for the back-end fuel cycle. French industrial actors for each segment of this cycle are shown in annex. The CEA is the research and development national entity sustaining the industrial efforts of the French companies involved in all stages of the fuel cycle : enrichment, fabrication, reprocessing, radwaste management. Such a cooperation assistance is devoted to processes developments, equipment qualification, engineering back up, as this will be reviewed along present communication. As well known, mastering a new technology from fundamental research to full scale industrial deployment, requires time and considerable financial commitments. Both CEA and COGEMA have devoted the requested time and funds to reach an effective industrialization of the closed fuel cycle. This industrial achievement is now completed. UP2 La Hague reprocessing unit produces effectively over 40 T per month and its capacity will be doubled to reach a nominal production of 800 T per year available in 1993 for our EDF domestic utility. It has recently reprocessed the two thousandth ton of LWR fuel and treated in 1987 over 400 T of the same, thus exceeding the nominal capacity. On the same site our UP3 unit under construction will be operating next year with a capacity of also 800 tons per year devoted to foreign utilities. Last year, in view of our excellent operational experience, Cogema reassessed the whole financial scheme for both plants including maintenance and refurbishing expenses. We may confirm that the reprocessing cost, after base load period ending in year 1999, will be reduced by 30 to 40%. The once through option does not effectively solve the spent fuel problem since to-day nobody has qualified an ultimate repository site associated with a licensed reliable process for irradiated fuel embedding

    Full Text Available Pensar la identidad se ha convertido en el reto intelectual de nuestro tiempo. Frente a la idea que la identidad es una categoría ontológica que puede definirse a sí misma, existe otra mirada que exige la incorporación de la dimensión histórica para su análisis. Este enfoque existencialista concibe la construcción de la identidad como un proceso socio-histórico caracterizado por un movimiento de construcción y reconstrucción, a través del cual los grupos sociales ven modificada sus representaciones sobre sí mismos y el mundo. La identidad nace acompañando la modernidad y su preocupación era cómo construirla, mantenerla sólida y estable. La contemporaneidad actual, hoy ya no concibe esta idea estática propia del mundo moderno, su problema reside en cómo evitar su fijación, manteniendo viva la diversidad de opciones. La posibilidad de comprensión del otro, diverso a nosotros, implica una concepción multidimensional de hombre, por lo tanto, necesita de una identidad pensada como un proceso de construcción siempre abierto. La modernidad fue testigo del proceso de construcción de la identidad, la contemporaneidad presencia su reconstrucción.

    Full Text Available En el imaginario de la sociedad de la ubicuidad, en el cual las comunicaciones digitales inciden de forma categórica en el desarrollo y la evolución de los nuevos ambientes comunicativos, las figuras de "emisor" y "receptor", así como los modelos que ayer permitían explicar el proceso comunicativo, hoy exhiben evidentes limitaciones en sus capacidades explicativas. La realidad los ha desbordado. En el desarrollo histórico de los medios de comunicación es posible advertir cómo éstos resienten determinadas remediaciones. Desde la perspectiva de la ecología de medios, Internet -el medio de comunicación inteligente-, admite ser comprendido como lógica extensión del telégrafo. El telégrafo representó la primera exteriorización de nuestro sistema nervioso. El desarrollo de las comunicaciones digitales móviles nos desplaza hacia un nuevo ambiente mediático: la "sociedad de la ubicuidad". De acuerdo con Neil Postman, detrás de toda tecnología subyace una filosofía, y los principios comunicativos de la "sociedad de la ubicuidad": comunicación para todos, en cualquier momento, en cualquier lugar, desplazan consigo la necesidad de producir los dispositivos de comunicaciones digitales móviles idóneos para responder a las exigencias del ambiente comunicativo que supone dicha sociedad. El desarrollo de la web 2.0 admite ser considerado como un auténtico parteaguas histórico en la evolución de Internet; éste impuso importantes cambios tanto en el comportamiento como en los hábitos de consumo cultural de los cibernautas. El cibernauta accedió a la condición de prosumidor. Debemos reconocer a los prosumidores como los actores comunicativos de la sociedad de la ubicuidad. El papel de los prosumidores resultará definitivo en las siguientes remediaciones que experimentará Internet, medio que definitivamente admite ser comprendido como lógica extensión de la inteligencia humana.

    Discussing the mobilization of environmental associations from the sole sociological viewpoint of interest and calculations is no longer workable. Similarly, although the processual analysis of commitment has obvious heuristic virtues, it could be usefully completed to understand how it emerges and gets structured. This is why, in order to further develop this kind of analysis, we shall explore the processes leading to forms of organized commitment. To do so, Canguilhem's research about the epistemology of living organisms will be used. It shows that, when the resolution of problems between individuals and their milieu is attempted, it is always initiated by the former. By using the notion of 'concernment' and articulating it with those of environment and orientated behaviour, we intend to emphasize the singularity of the social dynamics that aim to solve the tensions inherent in environmental issues. Furthermore, through sociological analysis, one may get a glimpse of forms of similarity between 'concernment', commitment and cognitive mobilization. Our research is based on comparative data drawn from two surveys on the nuclear industry in France: one in Limousin concerning the uranium industry and another in La Hague, North Cotentin, dealing with radioactive waste.

    Energy Technology Data Exchange (ETDEWEB)

    Garcia, K

    1998-12-31

    Excess dissolved plutonium has been measured in the coastal waters of the Channel, from Granville to Boulogne, probably due to sorption-desorption processus. In the Seine estuary, in situ measurements and experimental studies showed that the plutonium desorbs himself from particles in low salinity waters. The desorbed plutonium originates in marine and/or fluvial dissolved Pu. Marine dissolved Pu(V), originating from La Hague plant discharges and from atlantic waters, is reduced and sorbed when the salinity decreases onto estuarial particles: Isotopic Activity Ration {sup 238}Pu/{sup 239}, Pu(IR) of marine dissolved Pu(V) is about 0.7. Fluvial dissolved plutonium originates from atmospheric fallout and from an internal river source: fallout plutonium (IR=0.05) is unreactive with salinity while 45% of river plutonium (IR>1.7) flocculates at 0.5 g l{sup -1}. Desorbed plutonium may have various origins, depending on the Seine liquid discharges and on the tidal coefficient. When the marine waters do not migrate upstream, the low salinity waters encounters particles marked essentially with marine plutonium and the IR of desorbed Pu is about 0.7. The activities of desorbed plutonium are too low to have any influence on the distribution of plutonium in the coastal waters on the Seine Bay. When the marine waters migrate upstream, the low salinity waters meet particles marked essentially with river plutonium (IR>1.7) and desorbed plutonium has a very high IR. These estuarine conditions are encountered five to seven month a year and implicate an increase of the IR of 0.1 of the plutonium present in the coastal waters of the Seine bay (1.2.-1.3.).

El fundamento místico de la autoridad, en el cual el autor analiza, como indica el título del ensayo, los fundamentos (narraciones, e ideas en que se basa la autoridad del Derecho. Se busca cruzar el análisis que lleva adelante Derrida de las obras de autores como Pascal, Montaigne, Walter Benjamin, Kafka, con las preguntas actuales de la filosofía legal, como ser el basamento (meramente conjetural, hipotético, presupuesto de la norma fundamental de Kelsen o la vinculación entre el Derecho y la Moral, el Derecho y la Justicia, el Derecho y la violencia. El punto central a que se dedica el autor es interrogar el concepto de violencia. Trata de precisar quién, por qué y cómo detenta el máximo poder: el poder de nombrar qué es lo que es violento. Y qué es lo que no. “¿Que diferencia hay entre la fuerza de la ley y la mera violencia que consideramos injusta?” Esta es la pregunta fundamental que inspira el texto de Derrida, pero también es la pregunta que ha inspirado desde siempre a los abogados.

    Full Text Available La historia de la cultura de un pueblo puede leerse en los procesos de lectura y escritura que implican tanto determinadas prácticas sociales como los textos resultantes. En los últimos años, los relatos -esa capacidad humana de creación y representación del mundo- se han metamorfoseado tanto en su estructura como en la sustancia que trabajan. De allí que la historia de Córdoba puede aparecer como un recorrido desde esos relatos diferentes que buscan representar el mundo y ya no crear un mundo desde la ficción. Estas reflexiones -resultado de un proceso de investigación más amplio- pretenden señalar estas posibilidades desde un tipo de relatos: los no ficcionales, la novela histórica y el periodismo de investigación. Formas de escribir, pero también distintas formas de leer como un acceso a la construcción del mundo. Formas que ahora pretenden solamente mostrarlo, interpretarlo y representarlo discursivamente. Los textos analizados representan 'estas formas' y permiten -a su vez- una lectura desde la historia de Córdoba desde otro lugar.

    These last years the formation of solid deposits has been observed in the dissolution workshops of the La Hague plant. A sample of the solid was withdrawn for expertise: molybdenum and zirconium are the two major components of the solid, identified as zirconium molybdate. This thesis consisted in the approach of the mechanisms in solution liable to induce precipitate formation. After a bibliographical overview on the chemistry of Mo(VI) in highly acidic solution, this system was studied by absorption spectrophotometry in perchloric medium. The implication of two major forms of Mo(VI) in a dimerization equilibrium was confirmed by this way and by {sup 95}Mo NMR. The principal parameters governing this equilibrium were identified. It is thus shown that the molybdenum dimerization reaction is exothermic. Disturbance of the Mo(VI) system in highly acidic solution by Zr(IV) was also studied. In a restricted experimental field, for which 'conventional' exploitation methodologies had to be adapted to the system, a main complex of stoichiometry 1:1 between Mo(VI) and Zr(IV) was found. The precipitation study of Mo(VI) by Zr(IV) under conditions close to those of the dissolution medium of nuclear spent fuel was undertaken. The main parameters which control precipitation kinetics were identified. The results obtained reveal that precipitation is controlled by a single macroscopic process and therefore can be described by a single equation. The solid obtained is composed of only one phase presenting a Mo:Zr non-stoichiometry when compared to the theoretical formula ZrMo{sub 2}O{sub 7}(OH){sub 2},2H{sub 2}O. At last, on the basis of the research results, a descriptive mechanism of the system is proposed in which intervenes a 1:1 intermediate complex, much more soluble than a probable 2:1 precipitation precursor.

    Full Text Available Tratar el tema de la educación desde la perspectiva de la pobreza obliga a plantear diversas cuestiones, entre las cuales Bracho (1995 destaca la manera en que se relacionan ambos fenómenos, si se relacionan, y si pueden o no ser problemas de política pública. Esta tendencia a vincular la educación con la pobreza no es exclusiva de una corriente analítica o de una zona específica, es más bien comprensible desde el contexto socioeconómico en el que se presenta dicha relación. Es sorprendente, por ejemplo, que un país con grandes recursos y oportunidades como México tenga un promedio de escolaridad, en 2011, de 8.6 años, por debajo de los 12 años que comprende la educación básica u obligatoria, y que más del 50% de la población total se encuentre en pobreza extrema. Partiendo de que la pobreza es la negación de las oportunidades y las opciones básicas para el desarrollo humano, así como la ausencia de determinadas capacidades elementales para realizarse, los individuos de hogares afectados por esta condición poseen menos oportunidades educativas que el resto de la población, debido en gran parte a factores como la lejanía respecto de los centros educativos, los altos costos de oportunidad, las bajas expectativas en el aprendizaje y el menor capital cultural con el que cuentan. Los hijos de los pobres desarrollan un capital inferior, tal atraso se reproduce una vez más en la siguiente generación, forjando una pobreza educativa intergeneracional. Del lado de la educación, las personas con más años de escolaridad tienen acceso a trabajos de alta productividad y mejores salarios, mientras que los individuos con baja escolaridad difícilmente logran obtener un mejor estatus social y salir de los círculos de la pobreza.

    Full Text Available Feminism has made in the last decades relevant advances towards equity between men and women in western societies. However, both mysogyny and gynophobia are still at work, giving as a result a «deflation of expectations» among women who enter the worlds of politics, information, corporations, economic power, knowledge, religion or art, and find a glass ceiling in full operation. The paper focuses on women artists, examines the anger expressed in feminist art as an answer to exclusion, and argues for feminist strategies of analysis and correction of inequalities.

    El feminismo ha conseguido en los últimos años importantes avances hacia la igualdad entre hombres y mujeres en las sociedades occidentales. Y, sin embargo, tanto la misoginia como la ginofobia siguen vigentes, provocando una «deflación de expectativas » entre las mujeres que se incorporan a los mundos de la política, la información, las organizaciones empresariales, el poder económico, el saber, la religión o la creatividad, y se topan con el techo de cristal a pleno funcionamiento. El artículo se centra en las mujeres creadoras para examinar la cólera expresada en el arte feminista como respuesta a la exclusión y defender estrategias feministas de análisis y corrección de desigualdades.

    Full Text Available At the end of the XVIII century, in Caracas, a promenade related to Paseo del Prado, Madrid, was projected by the Governor Manuel González y Torres de Navarra. Small evidence of its construction has led some historians to assert that la alameda was never built. However, after examining historic documents, old maps and planes or the city, this article advances the alameda was indeed built to survive the 1812's earthquake, and the Independence war. In 1858, another promenade, el paseo de Caracas was projected on the same site were la alameda was once located.

    A finales del siglo XVIII, y promovida por el gobernador Manuel González y Torres de Navarra, se proyectó en la provincia de Caracas una alameda que estaría emparentada con el Paseo del Prado de Madrid. La escasa información sobre este proyecto ha contribuido a que muchos historiadores duden de su existencia. Sin embargo, la revisión de fuentes documentales y antiguos planos de la ciudad permiten deducir que la alameda no sólo se construyó, sino que sobrevivió a los embates del terremoto de 1812 y la Guerra de Independencia, sirviendo de base para la propuesta del Paseo de Caracas que, en 1858, se propuso en ese mismo lugar.

    The Compagnie Generale des Matieres Nucleaires is currently exploiting several steep vein uranium deposits in France. The upper parts are exploited using the open-cast method, in the lower parts underground mining is used. The veins with a thickness of several meters fill faults caused by tectonic activity. With regard to the low strength of the rocks, wooden supports are used or fills. In the course of the past 25 years several mining methods have been tried of which overhand stoping was selected with an oblique ramp driven in the ore, this mainly for securing operating safety and the profitability of selective exploitation. In overburdens with a low bearing capacity the method of underhand benching in slices was used with a concrete fill and later underhand benching in slices with concrete reinforcing plates. Overhand stoping is being tried with fill and electric self-propelled machines left in the stope and mechanized driving of raises by full profile drilling. (B.S.)

The objective is to define a non-destructive nuclear measurement facility that makes it possible to: - sort the packages stored on the site according to the radiological acceptance criteria for the waste packages in the surface storage facility, - establish the β and α activities of the packages to be stored in the surface storage facility, - estimate the activity of the packages that will be stored in the ''Entreposage Intermediaire Polyvalent'' (multiple purpose intermediate storage) built on the Marcoule site. A measurement facility, with measurement times compatible with the industrial flow of retrieval of the waste drums was studied, developed and will be validated. It features gamma spectrometry measurements and neutron measurement devices, associated to an imaging device by photonic transmission and an expert system. Studies associated to the definition of this facility mainly concern: - the imaging station: it enables to know up to what height the packages are filled, the actual density of the matrix, and to detect lacks of homogeneity. These data are required for a correct analysis of the neutron or gamma measurements and to minimise uncertainties, - the interpretation of active neutron measurement signals: a simultaneous detection of the prompt and delayed neutrons makes it possible to differentiate the masses of U-235 and of Pu-239 present in the packages, - the reduction of the detection limits: to that end, an ''asti-Compton'' detector was defined providing a gain on the detection limits at low energies according to the type of GeHP semi-conductor detector. - the expert system which performs the interpretation and coupling of measured data with data coming from the waste production files in order to determine the activity of the β γ, pure β and α radionuclides at 300 years. The validation program that will be conducted on a real size prototype makes it possible to demonstrate the performances of the proposed methods and devices. The implementation of these methods or devices makes it possible to reduce the influence of dominant parameters in the calculation of the uncertainty associated to the establishment of the radiological activity contained in the packages of irradiating waste.

    Full Text Available La narrativa cumple un papel determinante en la relación paciente-médico-enfermedad. Ponerse en el lugar del médico, del enfermo, de la enfermedad y del contexto mismo constituye una fuente rica y plena de entendimiento y comprensión del desequilibrio, de la carencia de la salud y de las posibilidades de explicación del dolor y de la experiencia de la enfermedad y de la muerte. Las metáforas dadas por la literatura, u otras formas narrativas, brindan la posibilidad de visualizar el papel de la bioética, los agentes e intervinientes en el proceso de alteración de la salud y el proceso en sí mismo. La narrativa y las ficciones estéticas como mediaciones en la curación y el cuidado suponen unos elementos básicos sobre los cuales se establece la comunicación, el diálogo y el contexto entre los curadores, los cuidadores, el paciente, la enfermedad y la muerte. La metáfora de ponerse en el lugar de otro, aun en la personificación de la enfermedad, la memoria o la muerte facultan la eliminación de obstáculos, brindan la posibilidad de un análisis objetivo y hacen pensar en la necesidad de fomentar una competencia narrativa en los agentes intervinientes en el proceso.

  18. Potentiality of hydroxylamine nitrate as a scrubbing reagent to trap iodine and nitrogen oxides in nuclear spent fuel dissolution off-gas

    International Nuclear Information System (INIS)

    Cau Dit Coumes, C.

    1998-01-01

    The management of low and medium-level radioactive effluents, newly implemented in Cogema-La Hague plants, foresee to replace tarring by vitrification. This process change imposes to greatly reduce the saline content of the effluents and in particular the sodium content to improve the leaching resistance of glass. Studies have been carried out to find a substitute to soda, today used to trap iodine and nitrogen oxides by counterflow washing of spent fuel dissolution gases. The aim of this work is to evaluate the potentialities of hydroxylamine nitrate. After a presentation of the chemistry of iodine and inorganic nitrogenous compounds, the reactions susceptible to take place inside the washing column are identified. An experimental study of of the reactions of hydroxylamine with molecular iodine, methyl iodide, nitrous acid, and nitrogen oxides (NO, NO 2 , N 2 O 3 and N 2 O 4 ) has permitted to precise in each case, the products, the stoichiometry, the kinetics and the reaction mechanisms. The results obtained show that only an hydroxylamine acid solution allows to simultaneously reduce iodine into iodide and to eliminate the nitrous acid formed by the hydrolysis of nitrogen oxides. Two models of the iodine/iodide/nitrous acid/hydroxylamine reaction system are proposed in acid environment. The first one, established from the kinetic laws of the reactions involved, has only a restricted domain of validity. The second one, obtained by applying the experimental research methodology, is valid over a wider experimental domain and has been used to determine the favorable conditions for the simultaneous and fast reduction of iodine and nitrous acid by hydroxylamine.

  19. Determination of zirconium 93 and molybdenum 93 in reprocessing nuclear waste

    International Nuclear Information System (INIS)

    Puech, P.

    1998-01-01

    The aim of this work is to find new determination methods of zirconium 93 and molybdenum 93 (two long-lived radioelements) contained in reprocessing nuclear waste. 93 Zr has a very long period: 1.5 * 10 6 years. The measurement of this isotope is more performing by the ICP-MS method than by the classical radiochemical measurement methods. 93 Mo disintegrates with a radioactive period of 4000 years and can be detected by radiochemical measurement in particular by X spectrometry. But these radioelements cannot be directly measured on the reprocessing nuclear waste; they require a preliminary chemical separation (removing the radioelements able to interfere and those responsible of the radioactivity of the nuclear waste). The separation is implemented with very potentially selective techniques, using Mo and Zr specific extracting molecules: solvent extraction, emulsified liquid membrane extraction and liquid chromatography extraction (on a resin impregnated by solvent). Studies carried out in CEA/Cadarache, on a synthetic solution simulating a reprocessing nuclear waste, have allowed to show the selective properties of the L'-benzoinoxime for extracting Mo and of TBP for extracting Zr for the three studied techniques. The optimal extraction and separation conditions have been reached with a methodology including experiment plans. At last, the methods have been tested on real reprocessing nuclear waste at Cogema/La Hague. 93 Zr and 93 Mo have been measured in a dissolution solution and in a fission product solution. The obtained values are 2 * 10 6 Bq/l and 10 7 Bq/l for 93 Zr and 500 Bq/l for 93 Mo in a dissolution solution. These methods have allowed to determine too the isotopic compositions for Mo and Zr elements contained in reprocessing nuclear waste. The results are in accordance with those obtained with the Cesar code. (O.M.)

  20. Comparison of the local-scale atmospheric dispersion model Cedrat with 85KR measurements

    An accurate model of atmospheric dispersion of radionuclides over the complex terrain of the La Hague reprocessing plant (North Cotentin, France) has been developed by COGEMA, in partnership with Paris VI University. This model, called CEDRAT 1.0.1 (operational since October 2002), takes into account areas typically outside the validity limits of Gaussian models: relief and building influence, short-distance (beyond 500 m from the release point) and stable atmospheric conditions. The modelling tool is based on an original method: a 2D-meshed model for flow resolution at permanent rate in the prevailing wind direction, and a 3D description of the dispersion phenomena, taking into account wet and dry deposits, at permanent or transitory rate. This leads to an effective compromise between rapidity (45 min on a 6000 nodes grid, with a standard PC), robustness and accuracy, coupled with a user-friendly interface. Primarily the validation process consisted of a comparison with the 3D complex dispersion reference model MERCURE, developed by EDF. Then, MERCURE and CEDRAT results were compared on real release scenario basis, for which actual meteorological conditions and tracer data collected at monitoring stations around the site were known. To enlarge this validation process, a second level of comparison was made in collaboration with a IRSN Cherbourg team, through different field experiments, which provided both ground and elevated level measurements (collected with a captive balloon), for different stability classes of the atmosphere. The plume tracer is krypton 85, an inert gas released from a height of 100 m. Thus, the aim of this paper is to present the original method to describe short distance dispersion over complex terrain and its validation enrichment for stability conditions and areas not yet observed, through wind and cross-wind Atmospheric Transfer Coefficients comparisons, at both ground and elevated levels.

  1. Cross border transport of vitrified residues from France to Germany

    Graf, W.; Jussofie, A.

    2016-01-01

    Until 1994 reprocessing was the only legal way to manage German spent fuel. Since in 1984 the national reprocessing concept was abandoned the reprocessing abroad was the only existing disposal route. With the amendment of the Atomic Energy Act in 2002 spent fuel management changed completely since from 1 June 2005 any delivery of spent fuel to reprocessing plants was prohibited and the direct disposal of spent fuel became mandatory. Until 2005 the total amount of spent fuel to be reprocessed abroad added up to 6080 t HM, 5309 t HM thereof in France. According to the commercial contracts signed between the German utilities and COGEMA, now AREVA NC, in France and BNFL, now INS in UK, and to the intergovernmental agreements concluded between Germany and France or UK the waste generated from reprocessing has to be returned to Germany. The return of high active vitrified waste from La Hague to the interim storage facility at Gorleben was not only demanding from the view of safety ensured by the cask design but especially for security reasons since the Gorleben area served as a target for nuclear opponents from the first transport in 1996 to the latest one in 2010. The protection against sabotage of the railway lines and mass protests needed improved security measures. Special working forces and projects have been set up in France and Germany to cope with this situation. A complex transport organization was necessary to involve all parties in line with the German and French security requirements during transport. All transports have been completed successfully so far thus confirming the efficiency of the applied measures. (author)

  2. An example of R and D on safety assessment: study of a prolonged loss of cooling of halw (beyond design accident)

    1991-01-01

    The consequences of a loss of cooling of storage tanks of fission products concentrated solutions were studied, for a variable period, in the context, of the safety analysis of the COGEMA spent fuel reprocessing plants of La Hague. As a result of fission products-induced heat emission, a prolonger loss of cooling could involve the progressive evaporation of solutions up to dryout and lead to the formation of radioactive aerosols and then of volatile species of ruthenium likely to be released in off gas circuits of the tanks. With the aim of determining the radioactivity fraction likely to be transferred throughout the loss of cooling out of the storage tanks, an extensive R and D programme was performed, including the main following stages: - experimental determination of the factor of radioactivity transfer through aerosols out of the tanks; - modelling, by means of a calculation code, of the aerosols transfer into the off gas circuits; - experimental study of the ruthenium behaviour with tests carried out in laboratory, by evaporation of samples representative of nitric solutions of fission products. The main conclusions can be summarized as follows (by assuming a heat power density of 10 watts per litre of solution and a storage system completely adiabatic): - the evaporation of solutions starts more than 5 hours after the total loss of cooling, the 10 -4 value being an over-estimated value of the factor of radioactivity transfer by aerosols out of the tanks; - transfer factor through the off gas circuits varies, according to the physical characteristics of aerosols, from 0 to 8.10 -2 ; - ruthenium volatilized only during the final stage of evaporation, shortly before dryout; the minimum time to reach dryness is about 90 hours

  3. Fuel reprocessing: safety analysis of extraction cycles

    1991-01-01

    An essential part of the safety analysis related to the extraction cycles of reprocessing plants, is the analysis of their behaviour during steady-state and transient operations, by means of simulation codes. These codes are based on the chemical properties of the main species involved (distribution coefficient and kinetics) and the hydrodynamics inside the contactors (mixer-settlers and pulsed columns). These codes have been consolidated by comparison of calculations with experimental results. The safety analysis is essentially performed in two steps. The first step is a parametric sensitivity analysis of the chemical flowsheet operated: the effect of a misadjustment (flowrate of feed, solvent, etc) is evaluated by successive steady-state calculations. These calculations help the identification of the sensitive parameters for the risk of plutonium accumulation, while indicating the permissible level of misadjustment. These calculations also serve to identify the parameters which should be measured during plant operation. The second step is the study of transient regimes, for the most sensitive parameters related to plutonium accumulation risk. The aim is to confirm the conclusions of the first step and to check that the characteristic process parameters chosen effectively allow, the early and reliable detection of any drift towards a plutonium accumulating regime. The procedures to drive the process backwards to a specified convenient steady-state regime from a drifting-state are also verified. The identification of the sensitive parameters, the process status parameters and the process transient analysis, allow a good control of process operation. This procedure, applied to the first purification cycle of COGEMA's UP3-A La Hague plant has demonstrated the total safety of facility operations

  4. Perspective on the French closed fuel cycle: Open towards energy future and sustainability

    International Nuclear Information System (INIS)

    2006-01-01

    Energy sustainability and nuclear energy nowadays are far reaching issues with many implications and as a consequence, any long term sustainable strategy needs to be flexible. In France, nuclear energy (427 TWh in 2004, 80% of national electricity production) is a major asset for clean electricity production and for meeting Kyoto protocol objective in France. The decision to build a future EPR reactor in France has been taken. Regarding back end and fuel cycle, the current reprocessing and recycling strategy, with the existing industrial system (Cogema La Hague and Melox), has proven to be reliable and efficient. It enables to meet sustainability requirements, now and in the long run: ensuring a good management of high level waste through vitrification, reducing the amount of nuclear spent fuel in interim storage, recycling valuable nuclear material (Pu), keeping the possibility to use Pu concentrated in MOX spent fuel to start FBR in the future. To maintain this possibility for the far future, EDF considers that the Generation IV program is of major importance in order to develop future fast reactors able to use plutonium and to ensure a full utilization of uranium resource, while optimizing high level waste management. EDF strategy is to keep the nuclear option open in the future, with a two-steps approach for the renewal of the current nuclear fleet: first, around 2020, with the launching of generation III reactors like EPR, and second, depending on the energy demand, launching of Generation IV systems, around 2040 or beyond. To meet this energy prospect, R and D efforts must be devoted to fast breeder reactors (sodium cooled, which benefits already from industrial experience, and gas cooled, under consideration for R and D). Globally, this strategy is open to future progress and optimisation as needed to meet long term energy sustainability. It appears the necessity of a good consistency between all the components of the nuclear system: reactors, fuel cycle

  5. Stakeholder involvement in the management of effluent discharges from nuclear installations in France

    The involvement of local stakeholders in the decision-making process regarding health, safety and environmental issues is developing in many countries. As far as the management of effluent discharges from nuclear installations in France is concerned, members of Local Commission of Information, including elected people and NGOs, are playing an increasing role in that respect. To deepen the understanding of these risk governance processes, a working group of experts from different institutions was set up in 2000 by the Institute of Radiation Protection and Nuclear Safety (IRSN). The aim of this working group was to 1) analyse the stakeholder involvement processes already in place in France around nuclear and non-nuclear installations; 2) perform case studies of few national and international experiences around nuclear installations (notably concerning the revision of creation authorisation decree of COGEMA La Hague reprocessing plant, the environmental policy of BNFL Sellafield reprocessing plant, the discharges surveillance of EDF Fessenheim nuclear power plant); 3) study the evolution of the regulatory context for the stakeholder involvement. Four main elements, contributing to the social trust emerge from this analysis: 1) the social dynamics of the consultation process, notably with the emergence of 'new' stakeholders such as elected people and NGOs; 2) the readability of the plant follow-up from the point of view of local stakeholders and their involvement in the decision process (the relay role of these 'new' stakeholders); 3) the contribution of the institutional and pluralist expertise to the social trust (broadening of the range of values taken into account); 4) the issue of the local justification of the plant in the prospect of the sustainable development (no risk being acceptable without counter-parts). This paper will address these different issues on the basis of the case studies in the perspective of examining the radiological risk governance process

Se demuestra que a pesar de los esfuerzos por retrasar el desgaste del organismo, la vida se mantiene dirigida a la degradación; sin embargo, es posible minimizar algunos problemas causados por el envejecimiento manteniendo una vida más saludable, con ejercicio y buena alimentación.

    Full Text Available Experiencias en un país en desarrollo: tres empresas proveedoras de la minería construyen capacidades de innovar Alfredo del Valle, Eduardo Abarzúa, Fernando Contreras Ediciones Universidad Alberto Hurtado VER VERSIÓN ON LINE Santiago de Chile Este libro da a conocer una experiencia singular sobre el desarrollo de capacidades de innovación empresarial en un país en desarrollo. Se titula 'Innovar contra la Corriente' porque la experiencia se ha producido en el medio adverso a la innovación que caracteriza a estos países. Nuestra cultura dificulta y entorpece la innovación. La del mundo desarrollado, en cambio, la favorece y la estimula a todos los niveles. Solo podremos desarrollarnos si emprendemos la tarea clave de construir una nueva cultura, que promueva y apoye la innovación en cada empresa, en cada política pública y en la sociedad entera. Es una tarea ardua, porque exige enfrentar las culturas actuales y las prácticas asociadas a ellas, que nos rigen y nos condicionan en todos los planos sin que seamos conscientes de aquello. La experiencia se realizó en tres empresas chilenas -ARA WorleyParsons (ingeniería, Drillco Tools (herramientas de perforación y Enaex Servicios (servicios de explosión controlada- en conjunto con la Universidad Alberto Hurtado, que aportó la metodología: el Modelo de Innovación Participativa. Las culturas y sus prácticas son fruto de procesos de aprendizaje en la acción. Ellas no se transforman con simples tareas de capacitación o comunicación ni con eventos de impacto emocional, como suele proponerse, sino que requieren de procesos más profundos de movilización de personas y conocimientos, para la creación de valor y la creación organizacional. Esta experiencia ha tenido como rasgos distintivos su atención al carácter propio del mundo no desarrollado, su metodología sistémica y participativa, y un dispositivo de observación crítica del modelo utilizado, así como del proceso en las

    Full Text Available Los tumores de la nasofaringe son poco frecuentes en la infancia. Su forma clínica de presentación característica y la posibilidad de realizar un diagnóstico temprano e indicar el tratamiento oportuno, permitiría modificar favorablemente la evolución y el pronóstico de estos pacientes. Se reporta una serie de 4 niños con tumores de la nasofaringe (2 linfoepiteliomas y 2 neuroblastomas atendidos en el Hospital Infantil Docente "Pedro Borrás Astorga". Todos los pacientes mostraron en algún momento de su evolución obstrucción nasal unilateral y epistaxis. El 50 % de los casos comenzó su enfermedad presentando cefaleas y uno de ellos lo hizo con compromiso de pares craneales (VII, VI, IV, VI. La radioterapia representa la modalidad de tratamiento más útil y la resonancia magnética nuclear resulta de gran valor para el diagnóstico inicial, así como para la identificación de la recidiva tumoral.Nasopharyngeal tumors are infrequent in childhood.

    Full Text Available Partiendo del propósito de castellanizar y exaltar la dinastía regia fundada o propiciada por Fernando I, los autores de la Crónica najerense fueron llevados a ensalzar en muchos campos el protagonismo histórico de la mujer. Al contrario de la tradición historiográfica astur-leonesa e incluso gallega, éstos aceptaron y valoraron la intervención de la mujer en el ámbito público de los poderes seculares. Las mujeres de la Najerense, sólo en apariencia buenas o malas, pues todas son o legitimadoras o fundadoras, son a fin de cuentas expresiones varias de la emergencia, en la historiografía regia, de un sujeto femenino pleno y cabal de la historia.Partant du projet de castillaniser et d’exalter la dynastie royale fondée ou préparée par Ferdinand Ier, les auteurs de la Chronica naiarensis furent amenés à louer dans bien des domaines l’action historique de la femme. Au contraire de la tradition historiographique astur-léonaise et même galicienne, ces hommes acceptèrent et valorisèrent l’intervention publique des femmes dans les affaires séculières. Les femmes de la Naiarensis ne sont bonnes ou mauvaises qu’en apparence. Toutes légitimatrices ou fondatrices, elles ne font au bout du compte qu’exprimer diversement l’émergence dans l’historiographie royale d’un sujet féminin plein et entier de l’histoire.

O, si se quiere, de las letras, para el caso de querer precisar en lo escrito aquello que por sí es un infinito de creación, sutileza y adivinación, y por lo tanto imposible de amenguar con la limitación de definiciones exáctas.

    Full Text Available En las sociedades contemporáneas, los procesos de industrialización han tenido como consecuencia directa el crecimiento de la población urbana. El aumento de ésta ha provocado la concentración en las grandes ciudades y un grave desequilibrio que se refleja en la insatisfacción de necesidades sociales básicas 1. La ciudad de México ha sido, desde su fundación en 1521, centro del poder político, económico y cultural. Esto produjo desde su embrionario crecimiento en la colonia un desarrollo desequilibrado y desigual. Y a partir del triunfo de la revolución, con las políticas de infraestructura y el crecimiento demográfico, el distrito federal se transformó de pequeña comunidad urbana en una megalópolis en los años ochenta.
