    1987-01-01

    This is a systematic compilation of the material which was dealt with at the level of the German-French Commission (on questions of the safety of nuclear installations) in this discussions about the nuclear power plant at Cattenom. As a supplement to the report published already in 1982, the Commission has officially released its deliberation results on the subjects constructive safety measures, radiological effects, and precautions in case of an emergency. The allegations according to which the installation is wanting in safety are countered by the joint statement of the chairmen of GPR (Permanent Group on Reactors) and RSK (German Commission on Reactor Safety) of August 29, 1986.

  2. Safety technology comments on Cattenom nuclear power station

    International Nuclear Information System (INIS)

    1986-01-01

    The comments are based on the safety report for the identical Flamanville plant, on the contract documents for the DUP and on results of consultancy by the DFK Working Party and on replies from the French side in the context of a German list of questions. The comments refer to the state in spring 1982. According to the agreement made for the catalogue of questions Cattenom/KKP 2, the 1300 MW Philippsburg II nuclear power station is used as a German comparable plant in these comments. Reference is made to the German comparable plant in the description and assessment of important parts of the plant. The main points of the safety technology comments are in the assessment of site characteristics; the safety technology concept; the derivation of radio-active materials and the radiation exposure in the adjacent German area.

    Full text: An international team of nuclear installation safety experts led by the International Atomic Energy Agency (IAEA) has reviewed operational safety at France's Cattenom Nuclear Power Plant (NPP) noting a series of good practices as well as recommendations and suggestions to reinforce them. The IAEA assembled an international team of experts at the request of the Government of France to conduct an Operational Safety Review (OSART) of Cattenom NPP. Under the leadership of the IAEA's Division of Nuclear Installation Safety in Vienna, the OSART team performed an in-depth operational safety review of the plant from 14 November to 1 December 2011. The team was made up of experts from Belgium, the Czech Republic, Finland, Germany, Hungary, Japan, Russia, Slovakia, South Africa, Sweden, Ukraine, the United Kingdom and the IAEA. The team at Cattenom conducted an in-depth review of the aspects essential to the safe operation of the NPP, which is largely under the control of the site management. The conclusions of the review are based on the IAEA's Safety Standards. The review covered the areas of Management, Organization and Administration; Training and Qualification; Operations; Maintenance; Technical Support; Operating Experience; Radiation Protection; Chemistry; Emergency Planning and Preparedness; and Severe Accident Management. Cattenom is the first plant in Europe to voluntarily undertake a Severe Accident Management review during an OSART review. The OSART team has identified good plant practices, which will be shared with the rest of the nuclear industry for consideration of their application. Examples include: Sheets are displayed in storage areas where combustible material is present - these sheets are updated readily and accurately by the area owner to ensure that the fire limits are complied with; A simple container is attached to the neutron source handling device to ensure ease and safety of operations and reduce possible radiation exposure during use

    International Nuclear Information System (INIS)

    2014-01-01

    A set of three articles describes and comments the organization implemented by the IRSN to assess the situation and its potential consequences in case of nuclear or radiological accident. The first one indicates how a nuclear alert can be given, the commitment of regional and national authorities in relationship with the ASN and the IRSN, the role of the headquarters in Fontenay-aux-Roses and how they are informed, the possible presence on the accident site, and ways to ensure a transparent and pedagogical information. The second article comments a real-life test which has been organized about Cattenom, involving France, Luxemburg, Belgium and Germany. This real-life test was the occasion to test methods and measures which would be implemented in case of serious accident: this comprises checking a possible contamination of persons, sharing information with neighbouring countries, and the evacuation of thousands of people. The last article addresses the communication approach adopted by the IRSN, notably crisis communication

  15. Cattenom plant - Report on the complementary safety assessment of nuclear facilities in the light of the Fukushima accident

    International Nuclear Information System (INIS)

    2011-01-01

    This CSA (Complementary Safety Assessment) analyses the robustness of the Cattenom plant to extreme situations such as those that led to the Fukushima accident and proposes a series of improvements. Robustness is the ability for the plant to withstand events beyond the level for 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. Safety is not only a matter of design or of engineered systems, it is also a matter of organization. So issues like EDF's crisis organization, the organization of radiation protection, and work organization via subcontracting are also taken into consideration. The creation of a nuclear rapid action force (FARN) is proposed: this will be a national emergency force made up of specialized teams equipped to intervene in less than 24 hours on a nuclear site hit by an accident. This report is divided into 8 main chapters: 1) features of the site, 2) earthquake risk, 3) flooding risk, 4) risks due to other extreme natural disasters, 5) the loss of electrical power supplies and of heat sink, 6) management of severe accidents (accidents with core melt), 7) task subcontracting policy, 8) synthesis and list of improvements. 4 following appendices review: EDF's crisis organization, the FARN, radiation protection organization and accidental event trees.

    1993-05-01

    An underwater robot was tested in the basins of the Cattenom Nuclear Power Generation Center fed with raw water from the Moselle River. The purpose was to inspect wall biofouling without interrupting water circulation. The ROV is a light, compact device, remotely controlled by cable and equipped with video cameras. The video recordings made were used to compare conditions in a basin cleaned the previous month by divers with those in a basin which had not been cleaned for a year. Manual cleaning by divers is an effective method, leaving Zebra Mussels on less than 5% of the wall surfaces. On the other hand, the floor of the basin was observed to be covered with fine sediment, vegetal matters and shells washed in with the Moselle River water. In the basin which had not been cleaned, the entire wall surface was covered with very dense tufts of tubular organisms (Hydrozoa Cordylophora) and zebra mussels. The tests have provided elements for definition of an inspection procedure and have given rise to suggestions for complementary equipment. (authors). 5 figs., 9 photos

    The present note follows the exchanges with the contracting authority, the Cattenom nuclear power plant, during the public hearing stood on the 10. of october 2003 at Cattenom. In the frame of the evaluation of the inquiry file by WISE -Paris, this note constitutes a deepening on the question of authorization demands for the radioactive releases. The elements supplied by E.D.F in the file submitted to the inquiry, and the presentation of these demands and the information complements brought during the meeting of the 10. of october, raise different problems of evaluation and justification relative to the evolution of radioactive release of Cattenom. The note analyses in particular, the increasing of dosimetry impact expected from the progression of real release forecasted by the operator, and the weight linked to the feedback of clad failure problem. It discusses the justification brought by E.D.F. to the standing and even the increasing of liquid tritium release instead of the expected reduction, facing the arguments of the operator to the experience feedback on the park and to the uncertainties on the future progress.

    1984-01-01

    The French nuclear attache at the French Embassy in Washington discusses his country's energy program and his role at the embassy as a representative of the French nuclear industry. He reviews the nuclear program's growth since it began in 1945, and the impetus of the OPEC oil embargo to accelerate the program since 1973. The success of France's nuclear program is due to a convergence of reasons that include incentive, the existence of a single utility that could design and manage a project of this magnitude, and the decision to focus on the pressurized water reactor (PWR) built by a single supplier and offering the benefits of standardization. Controlling the fuel cycle is the basic philosophy of both the PWR and the breeder program. Barre recommends policies of pre-approved sites, standardization, and licensing reform for the US

    1980-11-01

    The French energy policy is supported by a lucid view of the situation of our country and the constraints linked to the international context. This statement implies, the definition of a French policy or energy production essentially based on national resources, uranium, and especially for long term, technical know how which allows using plutonium in breeder reactors. This policy implies an effort in R and D, and industrial development of nuclear field, both in reactor construction and at all levels of fuel cycle. This coherent scientific and financial effort has been pursued since the beginning of years 60, and has placed France among the first nuclear countries in the world. Now this effort enables the mastership of a strong nuclear industry capable to assure the energy future of the country [fr

  2. The French nuclear programme

    Bacher, Pierre

    1987-01-01

    France has a civil nuclear power generation programme second only to the USA with 49 nuclear units in operation and 13 under construction. The units in service are described. These include 33 PWR 900 MW and 9 PWR 1300 MW units. The electricity consumption and generation in France is illustrated. The absence of a powerful anti-nuclear lobby and two main technical options have contributed to the success of the French nuclear programme. These are the PWR design and the plant standardization policy which allows the setting up of an effective industrial complex (eg for analysis of operating conditions and of safety and reliability information). The programme and the reasons for its success are reviewed. Research programmes and future plans are also discussed. (UK)

  3. The French nuclear context

    1977-01-01

    The mean- and longer-range energy needs, that can be now forecasted in France, are analyzed, together with the special character of the French energy market. A resort to nuclear power is first shown to be necessary to limit the increase in the demand for imported fossil fuels, then this resort is shown to offer some real possibilities. The energy balance proves that the industrial stage of power plant construction is reached. The conditions of realization of the program have been settled with a set of provisions that render the risk and environmental impact as negligible as possible [fr

  4. French lessons in nuclear power

    International Nuclear Information System (INIS)

    Valenti, M.

    1991-01-01

    In stark contrast to the American atomic power experience is that of the French. Even the disaster at Chernobyl in 1986, which chilled nuclear programs throughout Western Europe, did not slow the pace of the nuclear program of the state-owned Electricite de France (EDF), based in Paris. Another five units are under construction and are scheduled to be connected to the French national power grid before the end of 1993. In 1989, the EDF's 58 nuclear reactors supplied 73 percent of French electrical needs, a higher percentage than any other country. In the United States, for example, only about 18 percent of electrical power is derived from the atom. Underpinning the success of nuclear energy in France is its use of standardized plant design and technology. This has been an imperative for the French nuclear power industry since 1974, when an intensive program of nuclear power plant construction began. It was then, in the aftermath of the first oil embargo, that the French government decided to reduce its dependence on imported oil by substituting atomic power sources for hydrocarbons. Other pillars supporting French nuclear success include retrofitting older plants with technological or design advances, intensive training of personnel, using robotic and computer aids to reduce downtime, controlling the entire nuclear fuel cycle, and maintaining a comprehensive public information effort about the nuclear program

    1990-01-01

    EDF has long been interested in the use of nuclear energy for thermal power generation. After a period of apprenticeship and experiments, EDF launched a major PWR plant programme so as to reduce France's energy dependence and master generation costs. This programme, based on standardization, has achieved the desired results. It must now be adapted to suit the needs of the 21st century. For this programme, all those involved (Governmental authorities, EDF, manufacturers) were mobilized to an unprecedented extent and rigorous working methods were imposed. Experience feedback has been used to make improvements both to the installations themselves and to procedures. Results have proved satisfactory as regards nuclear safety but vigilance must be maintained. Public opinion on nuclear power is reserved we are sentenced to achieving a 'fault-free' track record, all the while mastering costs, so as to ensure the continuing use of nuclear energy. (author)

    On March 21, 2005, the French minister of industry gave to the author of this document, the mission to shade a sociological light on the radioactive wastes perception by French people. The objective of this study was to supply an additional information before the laying down in 2006 of the decisions about the management of high-level and long-lived radioactive wastes. This inquiry, carried out between April 2004 and March 2005, stresses on the knowledge and doubts of the questioned people, on the vision they have of radioactive wastes and of their hazards, and on their opinion about the actors in concern (experts, nuclear companies, government, anti-nuclear groups, public). The last two parts of the report consider the different ways of waste management under study today, and the differences between the opinion of people living close to the Bure site and the opinion of people living in other regions.

  10. French opinion on Nuclear Energy

    International Nuclear Information System (INIS)

    Bucaille, A.

    2003-01-01

    Contrary to what many think or say, most French people do not have a clear-cut opinion about nuclear power. And until public opinion can be accurately assessed, we should be worried of speaking on its behalf. More than half the population of France believes that nuclear power is the cheapest option, but 40% of them have no idea what the situation really is. The French are keenly aware of the what is at stake at the international level, and the fact that energy is becoming a worldwide issue. What they are most concerned about is nuclear waste and the possibility of a catastrophe of the Chernobyl type occurring. Disquiet about the first is now dissipating, after having increased. But attitudes about the second are ambivalent. A quarter of the French are very ignorant about radioactivity. 20% of the population complain that not enough information is forthcoming, particularly as concerns advances in technology. As can be anticipated, awareness of the question of climate change is growing year by year, with increased reporting of storms, floods and heat waves

    In France nuclear industry is from far the industrial sector that has set the most numerous commissions that allow a dialogue with the public in order to favor transparency. There are 4 local structures of information: -)there are 38 Local Committees of Information (CLI) associated with nuclear facilities, -) the Information Committees (CI) associated with secret nuclear facilities, -) the Follow-up Committees (CSS) for facilities dedicated to the processing of wastes, and the Committees for the prevention of industrial pollution (SPPPI). These committees involve numerous actors: public service, industrialists, supervisory authorities, elected representatives, employee representatives, members of associations and residents living nearby. Since 2000, 10 national public hearings around the 'atom' have been organized by the CNDP (National Commission for Public Consultation). Most actors of the nuclear industry allow residents living nearby to visit their installations, EDF ranks 3 as the company most visited with 400.000 people a year. Following the nuclear example the French chemical industry progressively moves toward more transparency. (A.C.)

    1991-02-01

    This report discusses the economics of the French nuclear power industry. It considers the dominant position of nuclear power in the French energy system, stresses the scale and causes of the current (1990) economic crisis and dispels the popular misconceptions on the cost efficiency of the French programme. The evidence is based on widely available French documents and articles. The report begins by looking at the background of nuclear power in France then discusses the problem of overcapacity, the technical problems and fall in load factors, generating costs and electricity prices and finally, strategic issues are considered.

    This is an account of a paper appeared in Energy Economist, February 1988 and contains a severe critique of the French nuclear power policy, in particular the Electricite de France, Cogema and Framatome. It is argued that the blueprint of the original nuclear power program has not been achieved in many topics. Points of critique to the EdF are: the electricity price, overcapacities and financial indeptedness. The French industries are not flourishing due to ample supply of cheap energy, nor do French nuclear manufacturers sell the fast breeder technology throughout the world. (qui)

  15. The cost of French military nuclear programs

    Barrillot, B.

    1999-02-01

    The author tries to find out the real cost of French nuclear weaponry. According to this study the total cost of the French military nuclear programs for 1960-1998 period is about 1499 milliard francs (MdF). This cost can be distributed as follows: i) fabrication of the bomb: 690 MdF; ii) display of the bomb: 727 MdF; iii) control of the bomb: 50 Mdf; iv) protection against nuclear attacks: 9 MdF; and v) dismantling of the bomb: 23 MdF. It goes without saying that these figures exceed by far those given by French authorities. (A.C.)

    1985-10-01

    With the help of two files respectively from the Institut geographique national (IGN) containing the geographic reference of all cities in France, and from the Institut national de la statistique et des etudes economiques (INSEE) containing the population figures of the 1982 census, the distribution of the population around a geographic point can be determined according to a given grid. Tables of population distribution around the 30 french nuclear sites were obtained by this method; however, at a short distance from a site, a detailed local examination/survey/investigation is necessary. Data shall have to be collected to estimate the non-french population around frontier sites [fr

  2. French nuclear power plants for heat generation

    International Nuclear Information System (INIS)

    Girard, Y.

    1984-01-01

    The considerable importance that France attributes to nuclear energy is well known even though as a result of the economic crisis and the energy savings it is possible to observe a certain downward trend in the rate at which new power plants are being started up. In July 1983, a symbolic turning-point was reached - at more than 10 thousand million kW.h nuclear power accounted, for the first time, for more than 50% of the total amount of electricity generated, or approx. 80% of the total electricity output of thermal origin. On the other hand, the direct contribution - excluding the use of electricity - of nuclear energy to the heat market in France remains virtually nil. The first part of this paper discusses the prospects and realities of the application, at low and intermediate temperatures, of nuclear heat in France, while the second part describes the French nuclear projects best suited to the heat market (excluding high temperatures).

  3. French public opinion and nuclear energy

    International Nuclear Information System (INIS)

    Le Ngoc, B.

    2016-01-01

    Since the beginning of the year French media have dealt with a lot of negative information concerning nuclear industry: the dire financial situation of AREVA, the questioning about the state of the pressure vessel of the Flamanville EPR or the EDF and Chinese investments in the british Hinkley point project. All these issues have impacted the opinion of the French people about nuclear energy: more people are against nuclear energy but nuclear accident appears to be only the tenth source of concern after unemployment (first) and terrorism. The debate about the energetic transition that will lead to the decrease of the nuclear share in the production of electricity marks the end of a political consensus in favour of the atom. Solar energy is the favorite energy source, more than 55% of the population wish solar energy to achieve a bigger share in the 15 next years while only 32% wish the same thing for wind energy. For most people nuclear energy appears to be necessary to complement renewable energies for at least the next 15-30 years. (A.C.)

    This article comments the difficulties and problems faced by Areva for its activity of nuclear reactor construction, and which leaded to the transfer of this activity from Areva to EDF while Areva will keep its uranium providing and fuel enrichment activities. These difficulties and problems concern the Flamanville EPR (the construction is 5 years late, vessel defects have just been identified, cost overruns), the Finnish EPR (7 years late, a 5 billions cost overrun), the Jules Horowitz research reactor (5 years late, cost overrun), and strategic choices (notably with respect to the post-Fukushima context). The article also outlines that other activities (mining, enrichment, reactor maintenance) are still doing well, and then briefly discusses the future of Areva NP

    Jusselin, F.

    1987-01-01

    Training dispensed by the EDF Nuclear and Fossil Generation Division has contributed significantly toward successful startup and operation of French nuclear power plants. In 1986, the time-based availability of 900 MW PWRs totaled 85 %. This is just one example of how EDF training programs have benefited from 150 reactor-years of operating experience and the ensuing opportunities for perfecting and testing of training tool effectiveness. These programs have been adopted by utilities in other countries where suitable local facilities are making advantageous use of EDF training experience and methods. EDF expertise is also transferred to these countries indirectly through the simulator manufacturer

  7. Industrial aspects of nuclear energy: French experience

    International Nuclear Information System (INIS)

    Lebreton, G.

    1986-11-01

    France decides to develop nuclear energy on a wide scale about 12 years ago. To cope with this ambitious program, the roles have been distributed within a very cohesive organization, as follows: EDF, the french national electricity utility is owner, prime contractor, and plant operator. The Atomic Energy Commission, CEA performs part of the research and development work, and supplies the necessary technical support to the safety authorities. A few leading industrial firms design and build the major parts of the nuclear power plants. Among them is Framatome, which is responsible for the design, manufacture, erection, and startup of nuclear steam supply systems (the NSSSs), and related auxiliaries. Alsthom is responsible for the supply of the turbine and its auxiliaries. It would not be proper to describe the French nuclear industry without focussing our attention on the care given to transfer of technology. Technology transfer agreements can take several forms, but local factors have to be taken into account. These forms are discussed in this paper. A typical and highly significant example (KNU 9-10 project) is given

  8. Nuclear: the decline of the French empire

    International Nuclear Information System (INIS)

    2011-01-01

    This issue first proposes critical articles which address the stumped revival of the world nuclear energy: overview of the world nuclear industry, a critic of the IAEA and NEA predictions, discussion of the financial risk, consequences of Chernobyl. A second set of articles comments the role and position of the French nuclear industry in the world. The authors outline the strong but fragile position of this self-declared leader (overview of the activities, abroad interests, mining activities abroad, and the end of foreign fuel processing activities) and discuss the diplomatic and commercial policy. Then, several articles discuss different aspects of the nuclear program in France: a climatic and energy policy transition impeded by the nuclear, an electric system under the nuclear constraint, an industrial policy characterized by an EPR monomania and stake holder concurrence, a nuclear safety put into question again, an always heavier weight of waste management, a dismantling industrialization which is a long time coming, the bad example of proliferation, and the secrets, uncertainty and spiral of the nuclear costs

    2015-08-01

    Ahead of the UN Climate Change Conference, including COP 21, to be held in Paris from 30 November to 11 December 2015, the IAEA released the French version of its scientific assessment of nuclear power’s role in meeting the climate–energy challenge: Changements Climatiques et Énergie Nucléaire. The report reiterates the fact that nuclear power is the second lowest CO2 emitter, considering emissions through entire life cycles, after hydro but ahead of wind and solar-based electricity. It also examines broader issues relevant to the climate change–nuclear energy nexus, such as costs, investments, financing, safety, waste management and non-proliferation. Recent developments in resource supply, changes in energy markets and technological developments are also presented

    Saudi Arabia is preparing itself to replace half fossil energies by a mix of nuclear and renewable energies. Although the nuclear program is not yet well implemented, Saudi Arabia and France have signed an agreement to develop cooperation in the nuclear sector. A joint committee was created to give a frame to assess the best practices in terms of nuclear regulations, waste management, scientific cooperation and training. Concerning nuclear regulations, waste management and scientific cooperation the French contacts of KACARE (King Abdullah City for Atomic and Renewable Energy) are respectively IRSN, ANDRA and CEA. Concerning scholar and professional training, a cooperation involving I2EN (International Institute for Nuclear Energy), EDF and AREVA on one side and the King Saud University, the Prince Mohammad University, the EFFAT University and the Dar Al Hekma College on the other side, has been set to develop training in nuclear engineering in Saudi Arabia. In parallel, AREVA and EDF have developed a program to find and qualify local subcontractors. (A.C.)

  11. Planning and developing the French nuclear programme

    International Nuclear Information System (INIS)

    Carle, R.

    1983-01-01

    Since France has been compelled to free itself from the domination of oil, it has undertaken a nuclear programme capable of providing for nearly one third of its energy needs by 1990. Some years after the first oil crisis, a good part of the battle has already been won: 22 reactor units of 900 MW each have been connected to the grid and account for 40% of the electricity produced in France, while 12 other 900 MW units, together with the first 1300 MW units, are under construction. Nuclear power has thus become an industrial reality possessed of the tools appropriate for the whole fuel cycle, which has managed to cope with costs and meet deadlines, and has developed a safe and reliable product. With these positive results despite inevitable incidents the French nuclear industry has come of age. There are, however, handicaps which remain to be overcome: high investment costs, operating constraints and continuing doubt on the part of the public. The efforts deployed in these three spheres are beginning to bear fruit. As a result, implementation of the French nuclear programme is being continued, albeit at a slower rate, for the aim is no longer to replace oil by nuclear power as soon as possible, but rather to keep up with the rise in consumption. In pursuing its nuclear efforts, France will henceforth be stressing progress in terms of quality, which can still be achieved in terms of increased reliability (incorporation of feedback), better economic return (initiation of a new series known as ''N4''), easier operation (improvement of the man-machine interface) and also more independence. The ''frenchification'' of the light-water reactor has from the beginning been seen as one of the means of achieving this independence. This also applies to mastery of the whole fuel cycle. And finally, fast breeders represent the next stage

  12. Ranking French nuclear industry on international market

    International Nuclear Information System (INIS)

    Labbe, B.

    1987-01-01

    Based on the success of its own ambitious nuclear power station program, France has been able to export its technology to many parts of the world, providing everything from individual components to complete power stations on a turnkey basis. Industrial partners who regurarly work together have set up the necessary structures to ensure the dovetailing of their activities during joint operations on the foreign market. These structures are matched to the needs of individual clients, and can be dispensed with completely in cases where a sole supplier is involved. Not one single unit under construction has been halted and no contract cancelled after the Chernobyl accident. France, like Japan and the USSR, is pressing on with its nuclear power program. China has ordered two PWR units for Daya Bay, while Britain has decided to construct its first PWR at Sizewell. Although a number of countries have deferred decisions in this field, this has been mainly on financial grounds. The French nuclear power industry has demonstrated its mastery of the technology, which can now be placed at the disposal of countries wishing to build nuclear power units, to improve their existing nuclear capacity, to develop parts of this future-oriented industry, or to supply their power stations with advanced nuclear fuel

    1988-01-01

    The financial problems of the nuclear power industry in France are explained. Cogema, the waste reprocessing company ventured into the French financial futures market and lost money. It is trying to sue its brokers over this disaster. Framatome, the State reactor manufacturer is trying to diversify into aeronautics, electronics and foodstuffs. The electric utility EdF is sliding into debt and, with no price rise allowed, this situation will get worse. Theoretically EdF should be delivering cheap electricity from nuclear power stations. However, French electricity prices are not significantly cheaper than those of Germany and the United Kingdom. The generating capacity will increase greatly over the next few years. The availability of existing plants is also improving. In spite of efforts to export its electricity (about 10% is exported) EdF seem unable to make its extra electricity cheaper and is heavily in debt. The fast breeder programme has also not lived up to expectations due to a sodium leak at Superphenix. (U.K.)

  18. Psychological empowerment in French nuclear power plants

    International Nuclear Information System (INIS)

    Fillol, Charlotte

    2011-01-01

    Since the eighties, nuclear safety has been discussed in organizational studies and constitutes nowadays a specific stream with several standpoints. Regarding the reliability of nuclear plants, the nuclear safety literature has emphasized on the crucial role of individuals and human factors. Especially, some researchers have noticed rule breaking behavior and the impact of individual self-confidence on the behavior; but without deepening their analyses. As high self-esteem and confidence, i.e. psychological empowerment, naturally lead to innovation and rule breaking, the behavior can be analyzed, in such a regulated industry, as opposite to safety. Thus, this article aims at explaining the roots and discernable features of the observed psychological empowerment. Methods include an in-depth qualitative study in 4 nuclear power plants owned by Electricite de France (EDF), the French national nuclear power operator. Focused on the leading team of the plant, the set of data is composed of 35 interviews, 6 weeks of non-participant observation and internal documents. The content analysis has revealed two main pillars of psychological empowerment. On the first hand, the strong professional identity developed at the opening of the plants is based on initiative and risk-taking. In some ways, this professional identify fostered by commitment to a demanding job and the team, influences behavior more than do professional rules. On the second hand, the management discourse is perceived as ambiguous towards the strict application of the rules and tacitly legitimizes rule breaking behavior. This article details and exemplifies these phenomena and discusses the implications. (author)

    The French regulation of the nuclear safety is based on the maintaining of a deep technical dialogue between the nuclear safety authority, the I.R.S.N. (Institute of radiation protection and nuclear safety) and the nuclear operators. This type of risk management is called 'french coking' by the Anglo-Saxons, followers of stricter regulatory approach, more readable by the civil society. This technical dialogue is not without quality, especially in the field of human and organizational factors where it allows to improve the know how situation that stays incomplete. (N.C.)

    Nuclear dissuasion is a slow and permanent process of adjustment to the strategic environment. French dissuasion adaptation to the new international environment covers a full decade, starting in the 1989-1992 era with a re-evaluation of defense programs. It has been followed by the 1994 defense white book which opens up the European perspective and reaches its peak in 1996 with a series of major decisions: renouncement of surface-to-surface missiles, launching of the M51 program, end of nuclear tests and shift towards simulation, dismantling of fissile materials production facilities etc. This process shows up two logics: the one of continuity with the confirmation of the bases of the French nuclear doctrine, and the one of discontinuity with significant changes in the general domain of the French nuclear policy. It also opens up questions about the field of application of dissuasion and the future of the nuclear consensus. (J.S.)

    2012-01-01

    France's strategic decision in favor of nuclear energy in the 1970's has given rise to an organization of this industry with clearly defined roles and responsibilities for all parties. This has led to the mastering of industrial production of the whole chain from mining to fuel reprocessing and to waste disposal. Nuclear safety was at any stage of the chain the priority number one. The French nuclear industry is present on the international scene and thus maintain its know-how and capacities despite the ups and downs of the nuclear market. Today 240.000 people work in France in the nuclear sector. France has followed a consistent energy policy during the last 50 years and benefits from an important and homogeneous fleet of reactors which has generated a rich feedback experience on reactor operation. The tasks that face the French nuclear industry are: -) to comply with the requirements of the Complementary Safety Assessments that have been performed on all French nuclear facilities, -) to maintain and upgrade the power plants (most of them are facing their 3. decennial overhaul), -) to prepare the nuclear systems of tomorrow, and -) to export the French know-how

    The nuclear instrumentation systems in power reactors in France have made considerable advances thanks to technological progress. The appearance of an integrated digital protection system (SPIN) and the extension of digital techniques have considerably improved performance and operating flexibility. Working on the basis of technology developed jointly with the Nuclear Electronics and Instrumentation Department at the French Atomic Energy Commission (CEA), Framatome and Merlin Gerin have designed the new nuclear instrumentation system for 1400 MW reactors.

    In France, the nuclear-development program is a high-priority objective of a strong, centralized government. The administrators responsible for its success can draw on concentrated fiscal and technical resources and are free to take decisive action. A major pillar of the entire French nuclear-development effort is the expectation of significant long-term export markets on all fronts: for nuclear power plants, uranium enrichment, and fuel reprocessing

    The author depicts the present situation and future of the French nuclear power programme which has now become a major industrial reality after successful acceptance of a twofold challenge: the technical problem and that of training the personnel responsible for operating the power stations. The large number of nuclear plants now in operation and planned for the next few years makes electricity generated from nuclear power a ''new industrial reality'', which we must still learn to utilize to the best effect [fr

    The question debated in this article concerns the demand of compensation and recognition of the impact on their health of nuclear tests. The military personnel that worked during nuclear tests in French Polynesia and the Sahara sites, but also the inhabitants of the atolls of Moruroa and Fangataufa equally in French Polynesia. An observatory of the veterans health has been created in order to improve the medical management of military personnel and former military personnel. An association 'Moruroa e tatou' contains the Polynesian former workers of the Nuclear tests of the Pacific and the association A.V.E.N. contains the veterans of nuclear tests. numerous examples are detailed. The question is tackled too for the consequences on health of the British nuclear tests, in Australia, Christmas Islands, and New Zealand. (N.C.)

  17. Computer Security at Nuclear Facilities (French Edition)

    International Nuclear Information System (INIS)

    2013-01-01

    The possibility that nuclear or other radioactive material could be used for malicious purposes cannot be ruled out in the current global situation. States have responded to this risk by engaging in a collective commitment to strengthen the protection and control of such material and to respond effectively to nuclear security events. States have agreed to strengthen existing instruments and have established new international legal instruments to enhance nuclear security worldwide. Nuclear security is fundamental in the management of nuclear technologies and in applications where nuclear or other radioactive material is used or transported. Through its Nuclear Security Programme, the IAEA supports States to establish, maintain and sustain an effective nuclear security regime. The IAEA has adopted a comprehensive approach to nuclear security. This recognizes that an effective national nuclear security regime builds on: the implementation of relevant international legal instruments; information protection; physical protection; material accounting and control; detection of and response to trafficking in such material; national response plans; and contingency measures. With its Nuclear Security Series, the IAEA aims to assist States in implementing and sustaining such a regime in a coherent and integrated manner. The IAEA Nuclear Security Series comprises Nuclear Security Fundamentals, which include objectives and essential elements of a State's nuclear security regime; Recommendations; Implementing Guides; and Technical Guidance. Each State carries the full responsibility for nuclear security, specifically: to provide for the security of nuclear and other radioactive material and associated facilities and activities; to ensure the security of such material in use, storage or in transport; to combat illicit trafficking and the inadvertent movement of such material; and to be prepared to respond to a nuclear security event.

  19. Electricity supplies in a French nuclear power station

    International Nuclear Information System (INIS)

    2011-01-01

    As the operation of a nuclear power station requires a power supply system enabling this operation as well as the installation safety, this document describes how such systems are designed in the different French nuclear power stations to meet the requirements during a normal operation (when the station produces electricity) or when it is stopped, but also to ensure power supply to equipment ensuring safety functions during an incident or an accident occurring on the installation. More precisely, these safety functions are provided by two independent systems in the French nuclear power stations. Their operation is briefly described. Two different types of nuclear reactors are addressed: pressurised water reactors (PWR) of second generation, EPR (or PWR of third generation)

    In order to reinforce their partnership, EDF, CEA and AREVA have founded the France Nuclear Platform (FNP). FNP is a tripartite body that will allow EDF, CEA and AREVA to build a consistent common position to respond to the worldwide demand in terms of nuclear reactors, fuel cycle or spent fuel processing. Potential clients and particularly first-time buyers want to buy far more than nuclear reactors, they want to buy the whole experience of the most important nuclear operator in the world which is a guarantee of success, safety and security. In order to stay ahead of the competition, the French nuclear industry can rely on high quality standards, a policy of innovation and a well-developed safety culture. Today's promising markets for nuclear energy are concentrated in Asia: in China a growth rate of 60% over the next 15 years is expected for nuclear power, in India projects for the construction of several EPR are ongoing.

  3. Nuclear Power and Sustainable Development (French Edition)

    International Nuclear Information System (INIS)

    2008-01-01

    Any discussion of 21st century energy trends must take into account the global energy imbalance. Roughly 1.6 billion people still lack access to modern energy services, and few aspects of development - whether related to living standards, health care or industrial productivity - can take place without the requisite supply of energy. As we look to the century before us, the growth in energy demand will be substantial, and 'connecting the unconnected' will be a key to progress. Another challenge will be sustainability. How can we meet these growing energy needs without creating negative side effects that could compromise the living environment of future generations? Nuclear power is not a 'fix-all' option. It is a choice that has a place among the mix of solutions, and expectations for the expanding use of nuclear power are rising. In addition to the growth in demand, these expectations are driven by energy security concerns, nuclear power's low greenhouse gas emissions, and the sustained strong performance of nuclear plants. Each country must make its own energy choices; one size does not fit all. But for those countries interested in making nuclear power part of their sustainable development strategies, it is important that the nuclear power option be kept open and accessible [fr

    1987-07-01

    French regulations on boilers and pressure vessels have prevailed for a very long time, the first measure having been promulgated on 29 October 1823. Restraining the attention to nuclear pressure vessels it must be pointed out regulations and enforcement by public authorities are more stringent than they are for conventional pressure vessels. The first part of this paper will be devoted to regulations with a special attention to the decree of 26 February 1974 and to the practice of public authorities in this field with special attention given to the Bureau de Controle de la Construction Nucleaire (BCCN = Bureau of Inspection of Nuclear Design and Manufacturing). The second part of this paper will deal with the French construction codes for nuclear components RCC-M (water reactors) and RCC-MR (elevated temperature design)

  5. The cyber security of French nuclear installations: stakes and opportunities

    International Nuclear Information System (INIS)

    Marquez, Thierry

    2016-01-01

    Notably due to the development of the number of connected objects, nuclear installations, their supply chain and all the actors of the chain value are exposed to cyber risks, even if a recent study noticed that successful cyber attacks involving nuclear plants are rare, but real. Thus, the threat is actual and growing, and the IAEA is already working with Interpol on this issue. The author then describes how French actors (EDF, Areva, CEA) have introduced cyber-resilience to better anticipate and identify actual threats and critical vulnerabilities in order to protect infrastructures. He comments some strengthened regulatory measures introduced for the French nuclear sector, and continuous improvements brought in the field of cyber security. He shows that handling these risks is also an opportunity to develop crisis management tools through the development of a specific know-how which also has an industrial value

  6. French N4 Series Design and Manufacturing

    Lebreton, Gerard

    1989-01-01

    The construction contract for the first two N4 units. on the Chooz site close to the French-Belgian border (Chooz B1 and B2). was awarded by Electricite de France (EDF) to Fumarate in May 1984. At present, project construction is approximately 50% complete for unit B1. The main civil works are practically finished and the reactor vessel and the steam generator were delivered on site by mid-1988. The connection to the grid by 1991 appears quite feasible. Continuation of the French nuclear power programme in the 1990s, specifically on the CIVEX and Penly sites, is based on this model. The N4 thus follows the four-loop, 1,300 MW class series designated P.a. whose first unit is Cattenom 1, which will serve in the following as a reference to appreciate the design evolution of the N4 NSSS. The design evolutions selected to reach these objectives are in technical continuity with the previous series, integrate the vast experience gained within the French programme and abroad, and were supported by a large R and D programme and further by industrial qualification tests

    1990-01-01

    Establishing information centres proved to be advantageous in France. In this way, about 300 000 people visit nuclear power plants annually. EdF staff members periodically supply information to media people. Emphasis is also laid on good contacts with Members of Parliament, physicians, clergymen, teachers and politicians. The strategy of indirect communication is recognized: the utilities should not speak for themselves, it is better for somebody else to say the thing. No debates are organized with Greenpeace, who are too militant, irrational and untrustworthy. Municipalities where nuclear power plants are sited receive tax money from the plants (as from any other industrial plant), so that if the power plant is shut down, the population often demands that a new nuclear power plant be built there. Absolute transparency, openness and immediate response are vital in contacts with the public. (M.D.). 1 fig

    By proceeding with underground nuclear tests, France does not intend to abandon its legal position concerning the right to possess nuclear weapons. The author - a specialist on international law in these matters - discusses this position and clarifies its nuances. He goes on to deal with the problem of jus cogens, the restrictive law which certain circles would like to draw from the resolutions of the General Assembly of the United Nations and from common law. France rejects this process as one which opens new possibilities for arguing against its tests, albeit underground.

    The article discusses the desirability of integrated project management systems within the French nuclear power industry. Change in demand for nuclear generation facilities over the last two decades has necessitated a change of policy concerning organization, cost and planning within the industry. Large corporate systems can benefit from integrating equipment and bulk materials tracking. Project management for the nuclear industry will, in future, need to incorporate computer aided design tools and project management information systems data bases as well as equipment and planning data.

    2015-10-01

    It is now a matter of public record that France and the United States conducted in-depth cooperation on ballistic missiles and, later, on nuclear weapons safety and security starting with the Nixon and Pompidou Administrations. The existence of a deep France-US strategic nuclear cooperation exists as a historical counter-narrative to the notion of France as a fully independent nuclear power, but also as a reluctant US strategic partner. Today, both countries conceive of their interests globally, and share similar outlooks regarding strategic challenges from countries such as Russia, China, Pakistan, Iran and North Korea. The United States and France have worked particularly closely in the P5+1 context to reach a diplomatic solution to Iran's growing nuclear capabilities. As permanent members of the United Nations Security Council, they are key partners on crisis management, regarding Libya, Syria, or Ukraine. Cooperation on counter-terrorism has been stepped up since the events of January 2015 in France. The two countries cooperate closely in Sahel and in Iraq. This short briefing provides new information on past nuclear cooperation and seeks to address the following question: given the existence of deep US-UK and UK-French nuclear ties, would enhanced US-French cooperation - the 'third side of the triangle' - be useful either strategically, in terms of enhancing the stability of deterrence, or financially?

    While supposing the lifetime of all present PWR reactors would be extended to sixty years, the author compares two scenarios regarding the renewal of the French fleet of nuclear reactors: the first one over 40 years and the second one over 20 years. This renewal is based on the construction of EPR reactors at different rhythms. The author compares the associated production costs and assesses the exploitation costs. A renewal scenario over 40 years seems to give better results

    As civil liability for nuclear is a matter of discussion and initiatives at the European and international levels, the author proposes an overview of the legal framework of the French regime of civil liability for nuclear which is a combination of two international treaties (Paris and Brussels conventions) and a national arrangement (a 1968 law). He presents and comments the main characteristics of this regime (geographical scope of application, concerned activities, excluded events, covered damages, principles regarding operator's liability) and the improvements brought by Paris and Brussels convention review protocols

  18. French lessons - can they help the US nuclear industry?

    International Nuclear Information System (INIS)

    Jasper, J.M.

    1987-01-01

    Many analyses of the politics and economics of nuclear energy in the United States rely on comparisons of US reactor programs with those of France, which have proven to be more successful. The kernel of the comparison is that France has a large and growing nuclear system that produces most of the country's electricity, little political resistance, electric rates that are among the lowest in Europe, and independence from the vicissitudes of the oil markets. By contrast, in the US there are widespread political resistance and unfavorable public opinion, uncertainty about future plans for nuclear energy, and a generally costly set of reactors that produce about 15% of the country's electricity. What is more, the relatively expensive American plants are often thought of to be less safe than their cheaper French counterparts. In attempting to explain the French success and the US failure, observers have been all too prone to single out as the root cause a particular political or economic factor that differs between the two countries. One of the major shortcomings of this approach is that there are a number of relevant differences, any of which could play a part in affecting the countries' nuclear programs and which may not be easily changed. Moreover, implicit in each explanation is a prescription for how to aid the ailing nuclear industry in the United States--a prescription that may well be questionable

  19. French nuclear doctrine: in keeping with continuity and orthodoxy

    International Nuclear Information System (INIS)

    Sitt, Bernard

    2012-09-01

    Debate surrounding French nuclear doctrine was lively last July, and the noted opponents of the French deterrent, such as General Norlain and Paul Quiles, took the opportunity provided by the election of a new French President to speak out in favour of reviving the debate in favour of nuclear disarmament on the grounds that nuclear weapons have become ineffectual since the end of the Cold War, even though this argument was dealt with in detail in the White Paper on Defence publishing during the spring of 1994. Yet the President's choices suggest an unequivocal policy direction: The President boarded SSBN le Terrible on the 4 July, something none of his predecessors has done since Valery Giscard d'Estaing in 1974. As the Elysee Palace underlined, this gesture was meant to 'reaffirm French commitment to its deterrent'. It also follows on from the positions Mr Hollande adopted in December 2011 and March 2012 during the electoral campaign. During a simultaneous visit to the Ile Longue base, the Defence Minister made it clear that the French position revolved around sufficiency, thereby reiterating the previous posture, following President Sarkozy's announcement that the aerial component would be reduced by one third and the overall warheads capped at 300. On the 13 July, at the launch of the commission tasked with drafting a new White Paper on defence and security, the President confirmed from the outset 'the preservation of the nuclear deterrence strategy', thereby defining an unambiguous conceptual framework for this important exercise of strategic reflection. In his speech to open the Conference of the Ambassadors on the 27 August, he did not fail to recall that France is a permanent member of the Security Council Nuclear-Weapon State, following on from the tradition established by his predecessors. The continuation of the French deterrent thus appears fairly certain, even if the White Paper committee will also be tasked with formulating the best course between

  20. Operating nuclear plant feedback to ASME and French codes

    International Nuclear Information System (INIS)

    Journet, J.; O'Donnell, W.J.

    1996-01-01

    The French have an advantage in nuclear plant operating experience feedback due to the highly centralized nature of their nuclear industry. There is only one utility in charge of design as well as operations (EDF) and only one reactor vendor (Framatome). The ASME Code has played a key role in resolving technical issues in the design and operation of nuclear plants since the inception of nuclear power. The committee structure of the Code brings an ideal combination of senior technical people with both broad and specialized experience to bear on complex how safe is safe enough technical issues. The authors now see an even greater role for the ASME Code in a proposed new regulatory era for the US nuclear industry. The current legalistic confrontational regulatory era has been quite destructive. There now appears to be a real opportunity to begin a new era of technical consensus as the primary means for resolving safety issues. This change can quickly be brought about by having the industry take operating plant problems and regulatory technical issues directly to the ASME Code for timely resolution. Surprisingly, there is no institution in the US nuclear industry with such a mandate. In fact, the industry is organized to feedback through the Nuclear Regulatory Commission issues which could be far better resolved through the ASME Code. Major regulatory benefits can be achieved by closing this loop and providing systematic interaction with the ASME Code. The essential elements of a new regulatory era and ideas for organizing US institutional industry responsibilities, taken from the French experience, are described in this paper

    This report deals with the millennium problem from the point of view of French Nuclear Activities. The paper presents the millennium problem and its causes as well as the difficulties in achieving millennium compliance. The relationship between the computer systems and the safety of nuclear installations is addressed and, in this respect, the question of determining the analysis strategy at the IPSN is discussed. The necessity to set up a specific organisational system having tasks related to analysis of installation sensitivity, study of resources, tests, and contingency measures is maintained. Particularly, an analysis of PWR of EDF and other nuclear installations is presented. Also mentioned are the IPSN initiatives in support of its assessment as well as the IPSN's international actions to cope with the millennium bug challenge

  2. The French nuclear safety authority's experience with radioactive transport inspection

    International Nuclear Information System (INIS)

    Jacob, E.; Aguilar, J.

    2004-01-01

    About 300,000 radioactive material packages are transported annually in France. Most consist of radioisotopes for medical, pharmaceutical or industrial use. On the other hand, the nuclear industry deals with the transport of fuel cycle materials (uranium, fuel assemblies, etc.) and waste from power plants, reprocessing plants and research centers. France is also a transit country for shipments such as spent fuel packages from Switzerland or Germany, which are bound for Sellafield in Great Britain. The French nuclear safety authority (DGSNR: Directorate General for Nuclear Safety and Radioprotection) has been responsible since 1997 for the safety of radioactive material transport. This paper presents DGNSR's experience with transport inspection: a feedback of key points based on 300 inspections achieved during the past five years is given

    1991-01-01

    The new French nuclear robotic program launched by the CEA was started at the beginning of 1988 for the duration of two years and with the total subsidy of about 130 million French franc. This program includes the following four steps: the definition of model missions dedicated to inspection and intervention in nuclear environment, the system analysis to define the systems, functions and specifications required to perform these model missions, the technological development required to achieve these systems, and the design of demonstration models with the partial integration of the above developments. The whole program including these four steps is called SYROCO (modular SYstem for RObots COoperating in radioactive environment). The repair of leak in a pipe in a reprocessing cell, the model mission in a PWR nuclear power plant, autonomous load bearing mobile robots, squirrel concept light modular carrier concept, radiation hardening, mechanic, perception of environment, communication, control and simulation and the demonstration models are described. SHERPA project, perception management, force controlled manipulator, squirrel project, light modular carrier, processes and NAB model mission simulation are particularly mentioned

    Increasing electricity costs weigh on the performance of France's exports, and this should lead to 'prudence' regarding the rate at which France's nuclear plants are taken out of service, says a report from the council of economic analysis (CAE), an economic think tank that advises the French prime minister. Reducing the proportion of nuclear energy in the country's generation mix was part of French president Francois Hollande's agreement with the country's green parties during his election campaign and is one of the key issues being discussed in France's energy transition debate. The government has said that nuclear energy's share in the generation mix should be reduced from 75% to 50% by 2025. The only nuclear plant the government has committed to closing is France's oldest, the 1.8 GW Fessenheim plant. It is scheduled to close at the end of 2016, but the move has generated much debate. 'Nobody knows why Fessenheim should be closed. Because it is old? So what?' said a legal source close to the French energy market who asked to remain anonymous. 'It's a shame that the French energy transition debate is not dealing with fundamental questions. It's too political', said the source. Low electricity prices are a key factor in maintaining France's economic competitiveness in relation to other European countries, said the CAE report, which was published on 16 May. A 10% increase in power prices paid by industrial consumers would lead to a 1.9% average reduction in the value of France's exports, it said. The market share of France's exports fell 19% in 2005-10, one of the largest slumps in Europe, according to a report published last summer by the European Commission. The country's current account recorded a growing deficit from 2005 onwards, reaching -2.2% in 2011, with the trade balance for goods accounting for most of this deterioration, said the report. Although France's trade deficit improved in 2012, driven by aerospace sector sales and weak domestic demand, the

    Work on coding safety regulations applicable to large equipment was undertaken in France as of 1978 to accompany the construction of a French nuclear plant. The needs of manufacturers were threefold: translate the design rules from the American licensor, meet the safety objectives expressed in French regulations published at that time through coding of industrial practices (order of February 26, 1974) and stabilize the work reference system between the operator - consultant - and the manufacturer responsible for applying technical recommendations. Significant work was carried out by AFCEN (the French Association for the Design, Construction and Operating Supervision of the equipment for Electronuclear boilers), an association created for this purpose, leading to the publication of a collection of rules related to mechanical equipment for pressurised water reactors, RCC-M and RSE-M, which will be discussed later, and also in several other technical fields: particularly mechanical equipment in fast neutron reactors, RCC-MR, electricity (RCC-E), and fuel (RCC-C).

    As an immediate consequence of the Fukushima accident the French nuclear safety Authority (ASN) asked EDF to perform a complementary safety assessment for each nuclear power plant dealing with 3 points: 1) the consequences of exceptional natural disasters, 2) the consequences of total loss of electrical power, and 3) the management of emergency situations. The safety margin has to be assessed considering 3 main points: first a review of the conformity to the initial safety requirements, secondly the resistance to events overdoing what the facility was designed to stand for, and the feasibility of any modification susceptible to improve the safety of the facility. This article details the specifications of such assessment, the methodology followed by EDF, the task organization and the time schedule. (A.C.)

    The prevention of fire in French nuclear power plants has followed the evolution of safety regulations. Today fire hazards are no longer considered as classical industrial risks but as specific risks that deserve to be studied thoroughly and in a more formalized form. In the beginning of the eighties EDF was committed to the redaction of a technical referential against fire gathering all the directives applicable to the N4-type plant (1450 MW). In 1994 this technical referential was reconsidered and enlarged in order to involve 900 MW and 1300 MW units. In each nuclear power plant a PAI (plan against fire) has been elaborated so that the installation can be progressively upgraded according to the last standard defined by the technical referential.

    France began atmospheric nuclear testing at Mururoa and Fangataufa atolls in the South Pacific in July 1966. Following international protest, atmospheric testing ceased in August 1970. In late 1995, an International Geomechanical Commission (IGC) was created to assess the short- and long-term effects of underground nuclear testing on the stability and hydrology of Mururoa and Fangataufa. With the aid of its consultants, the Commission sought to develop its own understanding of the mechanics and consequences of the underground nuclear tests. It carried out extensive numerical analyses of shock wave effects, seismic wave propagation, slope stability and pre- and post-test hydrology. However, in its studies, the IGC was constrained to use the data made available to it by the French authorities. The Commission's report (International Geomechanical Commission 1998) has been submitted to the French Government. This article draws heavily on parts of that report. The Commission's observations and analyses show that there has been no apparent change, on the atoll scale, to the overall mechanical stability of either atoll as a consequence of the underground nuclear tests. The main observable consequences of the tests are underwater slope failures, open fractures on the rim surface and surface settlements. The fractures visible on the surface are generally associated with subsurface slope displacements and occur only in the carbonates. There is no evidence that slope failures or settlements have occurred in the underlying volcanics. There has been no significant change in the long-term (beyond 500 years) hydrology of either atoll. The IGC estimates that the long-term change in the natural groundwater flow will be no more than 1%. There are, however, significant short-term changes locally around the test sites, which are briefly outlined

  11. Complementary safety assessments - Report by the French Nuclear Safety Authority

    International Nuclear Information System (INIS)

    2011-12-01

    As an immediate consequence of the Fukushima accident, the French Authority of Nuclear Safety (ASN) launched a campaign of on-site inspections and asked operators (mainly EDF, AREVA and CEA) to make complementary assessments of the safety of the nuclear facilities they manage. The approach defined by ASN for the complementary safety assessments (CSA) is to study the behaviour of nuclear facilities in severe accidents situations caused by an off-site natural hazard according to accident scenarios exceeding the current baseline safety requirements. This approach can be broken into 2 phases: first conformity to current design and secondly an approach to the beyond design-basis scenarios built around the principle of defence in depth. 38 inspections were performed on issues linked to the causes of the Fukushima crisis. It appears that some sites have to reinforce the robustness of the heat sink. The CSA confirmed that the processes put into place at EDF to detect non-conformities were satisfactory. The complementary safety assessments demonstrated that the current seismic margins on the EDF nuclear reactors are satisfactory. With regard to flooding, the complementary safety assessments show that the complete reassessment carried out following the flooding of the Le Blayais nuclear power plant in 1999 offers the installations a high level of protection against the risk of flooding. Concerning the loss of electrical power supplies and the loss of cooling systems, the analysis of EDF's CSA reports showed that certain heat sink and electrical power supply loss scenarios can, if nothing is done, lead to core melt in just a few hours in the most unfavourable circumstances. As for nuclear facilities that are not power or experimental reactors, some difficulties have appeared to implement the CSA approach that was initially devised for reactors. Generally speaking, ASN considers that the safety of nuclear facilities must be made more robust to improbable risks which are not

  12. Experience of load following in French nuclear power plants

    1989-01-01

    The relative importance of the French nuclear programme has reached such a scale that nuclear power stations can no longer be operated in the base load mode: their capacity exceeded the network demands for 1200 hours in 1983 and it is estimated that this figure will move to 5200 hours in 1990; their power should be able to vary flexibly. These figures illustrate the policy of substituting nuclear power plants for fossil-fired plants and explain the need for nuclear units to provide a quality of service at least equal to that of their ''elders'', which, for several years, have regularly participated in load following. Electricite de France (EDF) therefore had to perform the studies and work necessary to provide nuclear units with the required modulation capacity. There are several grid requirements and three types of flexibility are to be distinguished. The first, load follow, is fundamental when adapting to demand. The second type of flexibility, frequency adjustment, is another important factor in the quality of the product delivered to the consumer. The third type of flexibility is participation in the spinning reserve. When automatic operations are inadequate, available power reserves must be used to support the gird. Load following operations are performed. The operating mode with load modulation is subject to authorisations issued by the governmental organisations responsible for nuclear safety. EDF and the manufacturers have had to prove that such operations remain compatible with safety under normal operating conditions and, in the event of incidents, modulation should be capable of considerably modifying the initial conditions.

    Roughly speaking, the French Nuclear Protection and Safety Institute's role is similar in the French situation to the NRC administration role but with less authority role, which corresponds to another body in France. They define themselves as a technical support of the safety authorities. On the other hand, they have their own research laboratories. Among them, the most famous are the Phebus reactor and the Cabri reactor about which we have heard a lot these two days. They work on safety but also on protection of man and environment, management of accident conditions, security of transport, and safeguards. They have a relationship with utilities and with government authorities. With the utilities they have two types of technical evaluations. They make detailed technical studies of the safety reports presented to the authorities by the utility. On the research side, they participate in common research programs to resolve issues and to increase knowledge and understanding about safety related questions. With the governmental authorities, their role is to give advice on safety reports of existing or being-built installations and on more general policy questions like, for example, the safety principle to apply to the next generation of power plants. The decisions are left to the safety authorities, but they give a lot of advice and detailed studies about questions of safety

    In France, the flooding risk has been taken into account since the beginning of the nuclear program and has been reinforced following operating feedback from French and international power plants. The main events which led to reinforcement were the partial flooding in the Blayais NPP that occurred in 1999 and the Fukushima accident in 2011. The current French fleet is composed of 58 PWR reactors located on 19 sites: 4 sites are sea side, 1 side is located on an estuary and all other are located on river side. The lessons learned from the Blayais event are: -) an update of the hazard evaluation of the risks, -) a new assessment of the sufficiency of the protective measures, and -) the taking into account of aggravating risks associated to support functions such as site inaccessibility, loss of off-site power, etc. The lessons learned from the Fukushima accident have confirmed and enhanced lessons from the Blayais event. In addition the Fukushima accident has underlined the need to have sufficient margins beyond the design to avoid cliff edge effects. The improvements implemented on the Blayais and the Belleville sites are detailed

    The Nuclear Production Division of EDF is comprised of 19 power stations (58 PWR reactors) and 2 national engineering organisations. Nuclear Inspection (IN) is an internal assessment unit of the EDF Nuclear Production Directorate. At the request of the Directorate, it carries out periodic evaluations of all the units of the division. The evaluation of the nuclear sites (EGE: Overall Excellence Assessment) is carried out every 4 years, an intermediate evaluation is also carried out between each EGE. These evaluations are independent of the WANO and IAEA evaluations. Exchanges are carried out between Nuclear Inspection and the other international operators (for example, USA (INPO), England, China...) to share site evaluation methods. These evaluations are carried out by a team of 30 inspectors, reinforced during each evaluation by 10 peers who come from the various French nuclear sites. Nuclear Inspection produces a performance standards document for each FUNCTIONAL AREA, which is based on the requirements of the company. On the whole, 13 areas are evaluated during each inspection, in particular: Management, Operations, Maintenance, Engineering and Chemistry. The area of reactor plant chemistry has been evaluated since 2009. The Chemistry performance standards document is written from the EDF internal requirements and international references. During site evaluations, all the performance standards are assessed for compliance. The Chemistry performance standards document is comprised of 3 topics: Management of plant chemistry, The respect of the chemical and radiochemical specifications, The condition of the laboratories and the sampling lines, measuring equipment, and chemical products. The evaluations carried out make it possible to define strengths and weaknesses which the sites must address. After each evaluation, the assessment is presented to the site management and to the director of EDF Nuclear Production. For 4 years these evaluations have allowed progress to

    This article, published in issue 80 of 'l'ACROnique du nucleaire', aims to retrace the early steps in the consideration of the possibility of a nuclear accident in France, with the inclusion of 'non-institutional' participants and applying the lessons learned in Belarus in the contaminated territories around the Chernobyl nuclear power plant. After a review of the origin of the involvement of the Association pour le Controle de la Radioactivite dans l'Ouest (ACRO) in addressing post-accident issues alongside the populations living in an environment polluted by radioactivity, it discusses, from the critical viewpoint of an NGO, the context and the working method adopted for this examination. This is followed by some key elements of the programme and unresolved questions about the available body of knowledge which motivates research and about the method adopted for the work. The conclusion, moderately optimistic, highlights some advances and limits arising during this exercise in a French nuclear scene which remains characterised by a centralized mode of management.

    In a nuclear facility, when a difference between the physical inventory listing and accountancy records is discovered, the French law (Article 11 of the 'Decret 81-512') requires a declaration to the High Civil Servant for Defence of the Ministry in charge of Industry. Moreover, according to article L.1333-13 of the Defence Code, in case of a suspicion of loss, theft or diversion of nuclear material, the licensee has to declare this event to the police. In the meantime, an investigation is carried out in the facility, and in cooperation with other facilities if necessary. These measures are aimed at: - Finding the lost nuclear material (if any), - Understand the causes of the problem, - Solve the differences by acting on the PIL or/and accountancy records, - Act to prevent any other occurrence of this kind of event. These actions can take place in the general field of a police investigation. After all these facts and information have been gathered, the licensee writes down a complete file which is transferred to the High Civil Servant for Defence of the Ministry in charge of Industry, in order to be analysed by his technical support body (IRSN). Thus, the IRSN is able to give its conclusion to the authority about this event, especially regarding: - The causes of the event, - Relevance and completeness of investigations, - Pertinence of the corrections, - Relevance of corrective actions, - Probability of another occurrence. This system is useful to ensure a complete follow-up of the events occurring in the various nuclear facilities in France, to have an extensive overview of the problems on a national scale. If an item is found in a facility A, numerous questions must be answered: - Where does it come from? - Since when is it in facility A? - How did it happened that this item has been transferred from facility B to facility A without the transfer of information? - We will consider these issues through examples. This kind of event can be potentially very rich in

    Following Russia's annexation of Crimea and aggression against Ukraine, members of NATO are again pondering the strength of Western deterrence. Over the course of the Ukraine crisis, President Vladimir Putin has repeatedly emphasised the potency of Russian nuclear weapons, announced new nuclear-weapons programmes and brushed off accusations that Russia is cheating on a number of arms-control agreements. Most ominously, Putin has declared that he would have been prepared to place Russian nuclear forces on alert - which implies threatening their use - had the annexation of Crimea met with serious resistance. The three NATO nuclear-weapons states - the United States, United Kingdom and France - must again contemplate how best to ensure that their very different nuclear forces strengthen NATO's nuclear deterrence against Russian aggression. There is a tendency among Western defence analysts to assume that, in the event of a major crisis, the three NATO nuclear-weapons states would be able to effectively coordinate their deterrence policies and communications. The stakes are so high, so the thinking goes, that the three parties would find a way to successfully manage the crisis together. Yet, recent experience in terms of trilateral crisis management and strategic communications is not encouraging. In 2013, the United States, the United Kingdom and France attempted to deter Syria from using chemical weapons. This ended up being one of the biggest deterrence fiascos in recent memory - a textbook example of how not to prevent adversaries from embarking on large-scale aggression. The president of the United States announced a 'red line' regarding Syrian use of chemical weapons. Although the red line was apparently drawn extemporaneously, at a press conference on 20 August 2012, London and Paris presumed that Washington was committed to the red line and followed suit with their own statements. Over the course of several months, Syria appears to have

    The French nuclear safety authority is responsible for the control of radiation protection in radiotherapy since 2002. Controls are based on the public health and the labour codes and on the procedures defined by the controlled health care facility for its quality and safety management system according to ASN decision No. 2008-DC-0103. Inspectors verify the adequacy of the quality and safety management procedures and their implementation, and select process steps on the basis of feedback from events notified to ASN. Topics of the inspection are communicated to the facility at the launch of a campaign, which enables them to anticipate the inspectors' expectations. In cases where they are not physicians, inspectors are not allowed to access information covered by medical confidentiality. The consulted documents must therefore be expunged of any patient-identifying information. Exchanges before the inspection are intended to facilitate the provision of documents that may be consulted. Finally, exchange slots between inspectors and the local professionals must be organized. Based on improvements achieved by the health care centres and on recommendations from a joint working group of radiotherapy professionals and the nuclear safety authority, changes will be made in the control procedure that will be implemented when developing the inspection program for 2016-2019.

    The Reactor Pressure Vessel life management of 56 PWR 3 loop and 4 loop reactors units was engaged by the French Utility EDF (Electricite de France) a few years ago and is yet on going on. This paper will present the work carried out within the framework of justifying why the 34 three loop reactor vessels will remain acceptable for operation for a lifetime of at least 40-years. A summary of the measures will be given. An overall review of actions will be presented describing the French approach, using important existing databases, including studies related to irradiation surveillance monitoring program and end of life fluence assessment. The last results obtained are based on generic integrity analyses for all categories of situations (normal upset emergency and faulted conditions) until the end of lifetime, postulating circumferential an radial kinds of flaw located in the stainless steel cladding or shallow sub-cladding area. The results of structural integrity analyses beginning with elastic computations and completed with three-dimensional finite element elastic plastic computations for envelope cases, are compared with code criteria for operating plants. The objective is to evaluate the margins on different parameters as RTNDT (Reference Nil Ductility Transition Temperature), toughness or crack size, to justify the global fitness for service of all these Reactor Pressure Vessels. The paper introduces EDF's maintenance strategy, related to integrity assessment, for those nuclear power plants under operation, based on NDE in-service inspection of the first thirty millimeters in the thickness of the wall and major surveillance programs of the vessels.

    Full text of publication follows: The fate of radionuclides in the geosphere and in particular their transfer in the biosphere constitutes an essential key point in relation with environmental issues as well as their effects on living organisms. In order to answer to such issues, an Environmental Nuclear Toxicology Programme (a French national programme) has been launched in 2001 for a period of 5 years. It is a resolutely forward-looking programme gathering all the main research institutes (CEA, CNRS, Inserm and Inra) and comprising 15 projects that pool the expertise of physicians, biologists, chemists, physicists... The programme's central thrust is the study of the biological effects of nuclear toxics, i.e., most part of the compounds encountered in the nuclear industry ( 3 H, Co, Cd, Se, Sr, Tc, I, Cs, Pb U, Pu) that may have a chemical and (or) radiological toxicity towards living organisms. Its objectives are to study the toxicology of the materials used, in particular in nuclear fuels, to analyse the biological effects of radionuclides (naturally-occurring or artificial) that may be present in the environment, and to examine the effects of chemically toxic metals, particularly the heavy metals, used in nuclear and medical research and industrial activities. For the radionuclides, the aim is to determine the potential health consequences of exposure to these materials and to make realistic estimates of exposure to the corresponding risks incurred. The main research topics concern three types of mechanisms in bacteria, plants and animals: - Mechanisms by which elements are transferred and transported from cell to cell; - Mechanisms by which toxics accumulate in cell compartment and organs; - Specific detoxification mechanisms. In all cases, special emphasis is placed on work that makes possible to compare the toxicity of different elements relative to a better known toxic chemical, such as cadmium or cobalt, and also, for as many elements as possible, work to

    The French electricity supply system is based on nuclear energy, with three quarters of total electricity production originating from nuclear power plants. The sector has grown continuously over a period of 60 years. For a long time the realms of politics and science were in consensus about the use of nuclear energy for civil purposes, but now the French nuclear dogma is increasingly being called into question as a result of the disaster in Fukushima, the German decision to phase out nuclear energy and European energy policy in general. How will France shape its future energy policy given these altered framework conditions?

    The realization of the programme of nuclear experiments in French Polynesia was accompanied by the installation by a radiological monitoring device of the environment, either the physical environment or biological, continental or marine, vegetable or animal, in order to make sure of the absence of risk for the populations. This device took all its importance with the tests carried out in the atmosphere between 1966 and 1974. Its implementation required important means in hardware and manpower with the intervention of civil and military or sometimes mixed organizations. The monitoring was naturally done in a very complete way in the zones close to the sites of tests, but also on the whole of the Polynesian territory, in particular the most populated atolls. It also carried, but in a less extended way, on remote zones, like the Andean countries, because of their geographical location. The results obtained by the various involved laboratories were gathered and interpreted in order to ensure information of the persons in charge and the authorities, in particular in Polynesia and through them the population. They were each year transmitted to the scientific committee of the United Nations for the study of the effects of ionizing radiations (UNSCEAR). The surveillance device is thus described, apart from the zones close to the zones of testing, with the presentation of the various implied organizations and the various monitoring programs.

    Full text: The decree setting up the Nuclear Safety Authority in 1973 entrusted it with international assignments whose objectives are still valid: - develop exchanges of information with foreign counterparts on regulatory systems and practices, on problems encountered in the nuclear safety field and on provisions made, with a view to enhancing its approach, and - becoming better acquainted with the actual operating practice of these Safety Authorities from which lessons could be learned for its own working procedures; - improving its position in the technical discussions with the French operators, since its arguments would be strengthened by practical knowledge of conditions abroad; - make known and explain the French approach and practices in the nuclear safety field and provide information on measures taken to deal with the problems encountered. This approach has several objectives: - promote the circulation of information on French positions on certain issues, such as very low level waste, for instance; - assist some countries wishing to create or modify their Nuclear Safety Authority, such as countries of the former USSR, the Central and Eastern European countries, and emerging countries on other continents; - help, when requested, foreign Safety Authorities required to issue permits for nuclear equipment of French origin; - provide the countries concerned with all relevant information on French nuclear installations located near their frontiers.

    The demand for hydrogen, driven by classical applications such as fertilizers or oil refining a well as new applications (synthetic fuels, fuel cells ... ) is growing significantly. Presently, most of the hydrogen produced in the world uses methane or another fossil feedstock, which is not a sustainable option, given the limited fossil resources and need to reduce CO 2 emissions. This stimulates the need to develop alternative processes of production which do not suffer from these drawbacks. Water decomposition combined with nuclear energy appears to be an attractive option. Low temperature electrolysis, even if it is used currently for limited amounts is a mature technology which can be generalized in the near future. However, this technology, which requires about 4 kWh of electricity per Nm 3 of hydrogen produced, is energy intensive and presents a low efficiency. Therefore the French Atomic Energy Commission (CEA) launched an extensive research and development program in 2001 in order to investigate advanced processes which could use directly the nuclear heat and present better economic potential. In the frame of this program, high temperature steam electrolysis along with several thermochemical cycles has been extensively studied. HTSE offers the advantage of reducing the electrical energy needed by substituting thermal energy, which promises to be cheaper. The need for electricity is also greatly reduced for the leading thermochemical cycles, the iodine-sulfur and the hybrid sulfur cycles, but they require high temperatures and hence coupling to a gas cooled reactor. Therefore interest is also paid to other processes such as the copper-chlorine cycle which operates at lower temperatures and could be coupled to other generation IV nuclear systems. The technical development of these processes involved acquisition of basic thermodynamic data, optimization of flowsheets, design and test of components and lab scale experiments in the kW range. This will demonstrate

    The aim of this paper is to study the effect of external photon radiation on the mortality of two populations of French nuclear workers: workers exposed only to external photon radiation and workers potentially exposed also to internal contamination or to neutrons. External photon radiation has been measured through individual dosimeters. Potential exposure to internal contamination or to neutrons has been assessed by experts on the basis of quantitative measurements or of worksite and type of activity. The mortality observed in each population was compared with that expected from national mortality statistics, by computing standardized mortality ratios. Dose-effect relationships were analyzed through trend tests and log-linear Poisson regressions. 14,796 workers were exposed only to external photon radiation; 14,408 workers were also potentially exposed to internal radiation or to neutrons. Between 1968 and 1994, the number of deaths is respectively, 645 and 1,197. The mean external photon dose was respectively, 3.7 and 12.9 mSv. Similar Healthy Worker Effects were observed in the two populations (SMR = 0.59). SMR of 2.41 90% CI [1.39-3.90] was observed for malignant melanoma among workers of the second population. Significant dose-effect relationships were observed: among workers exposed only to external photon radiation for leukemia except CLL and in the other population, for cancers and other diseases related to tobacco or alcohol consumption. Results differed between the two populations. The increase in leukemia risk with dose in the first population will have to be confirmed with extended follow-up. In the other population, results may have been confounded by alpha-emitters inhalation, tobacco, or alcohol consumption.

    The European Commission is working on 2 directives concerning nuclear energy: the first one is dedicated to nuclear safety and the second to the management of radioactive wastes and spent fuels. In the context of the widening of the European Union and of the inter-connection of the different electric power grids throughout Europe, the harmonization of the rules in the nuclear safety field is seen by manufacturers as a mean to achieve a fair competition between nuclear equipment supplying companies and by the French nuclear safety authorities (FNSA) as a mean to keep on improving nuclear safety and to be sure that competitiveness does not drive safety standards down. According to FNSA the 2 European directives could give a legal framework to the harmonization and should contain principles that reinforce the responsibility of each state. FNSA considers that the EPR (European pressurized water reactor) may be an efficient tool for the harmonization because of existing industrial cooperation programs between France and Germany and between France and Finland.

    This bibliographical note presents a book in which the author, after having recalled the history of the French nuclear force since the first nuclear test in 1960, and outlined the fact that France has been living under the protection of its own nuclear deterrence force since that date, presents the components of this nuclear strike force with its four nuclear submarines equipped to launch new generation missiles, its fifty fighter bomber aircraft equipped with the ASMP-A missile. He presents and discusses the mission of this nuclear force, discusses the relevancy of the deterrence strategy in the present context, and the significance of such a strategy for a European country like France. He wanders whether this strike force is still affordable for our country, which can be its benefits, whether this arsenal remains useful as it has been designed in the Cold War context. He also discusses the disarmament perspectives in an unsteady international environment where power and arms race logics prevail again

  15. Would the re-structuration of the French nuclear industry be necessary?

    Finon, D.

    2011-04-01

    In this paper we analyze the recent propositions to reorganize the French industry of reactors in view to increase its efficiency on the export markets. Based on a critic of the choices of reactor technologies offered to export market, the Roussely report published on June 2010 recommends to crown the French electricity utility as the leader of a so-called 'French team' and to let him free to negotiate the sale of reactor of any technology that it would prefer as a Gen-2 reactor for example, and to place the French nuclear reactor constructor in a position of sub-contractor. The government has not followed this recommendation rightly. Based on an analysis of the changing world market of reactors, we defuse the criticism addressed to Areva on his choice, as well as the recommendation to open the present catalog of reactors to other models. The analysis leads to underline the importance of Areva's technological and industrial resources and the limited advantages of the EDF's skills in matter of architect-engineering and nuclear operation for winning export contracts. At the end of the day the mercantile approach which motivates the promoters of this tentative reform for competing with entrants prosing low cost nuclear reactors has been disapproved by the government, and that before the Fukushima accidents. We conclude by observing that only a flexible coordination between French industrial players would be useful for improving export performances of the French nuclear industry. (author)

    After the French bid for the construction of a nuclear power plant in the United Arab Emirates (AE) failed in 2011, Assystem, a French engineering company decided to develop in the Middle-East and now has become one of the most important partners of KEPCO, the company in charge of constructing the Barakah plant in AE. In Turkey, Assystem has bought a Turkish enterprise to back the Franco-Japanese SINOP project and to initiate a partnership with Rosatom building the Akkuyu plant. Today Assystem has become an important player in nuclear industry and has been able to bring back to French nuclear industry its experience of different practices and know-how in international nuclear markets. Assystem employs 12.200 staff worldwide and realized a 908 Meuros turnover in 2015. (A.C.)

    2011-12-01

    After having recalled the organisation of nuclear safety and radiation protection regulation in France, presented the French nuclear safety regulations (acts, decrees, orders, ASN decisions, rules and guides), described the nuclear safety approach in France (the 'defense in depth' concept), and ASN's sanctions powers, this report presents the French approach to complementary safety assessments (CSAs) with their different types of specifications (those consistent with European specification, those broader than the European specifications, and those which take into account some situations resulting from a malevolent act), and with the different categories of facilities concerned by these CSAs. It presents the organisation of the targeted inspections and outlines the transparency of this action and public information. Then, after an overview of the French nuclear power plant fleet, it discusses how earthquakes, flooding, and other extreme natural phenomena related to flooding are taken into account in the design of facilities and in terms of evaluation of safety margins. It describes the consequences of some critical situations (loss of electrical power supplies and cooling systems) and how they could be dealt with. It also addresses the different aspects of a severe accident management (organisation, measures, and actions to be performed) and the conditions related to the use of outside contractors

    Like any other industry, the nuclear industry generates waste. This waste arises in the different successive stages of the fuel cycle, including nuclear power plants, and its physical and chemical properties vary greatly. What is special about it is the radioactivity it contains. Management of waste generated by spent fuel conditioning in nuclear reprocessing facilities, and which cannot be stored in surface repositories, according to current French regulations (ILW and HLW), is specifically discussed in this paper.

    The assessment of the impacts of the French nuclear program on atmosphere pollution is based on a macroeconomic long term model MELODY particularly detailed for the energy sector. The French energy strategy, characterized by its nuclear program, is compared with an alternative coal strategy based on coal-fired power plants. The coal strategy would have entailed different economic performances, a different energy balance, and, consequently, a different quality of air. For instance, by 1990, carbon emissions would have been 60% higher with the coal strategy; actually, they are 27% lower today than their 1973 level. The French nuclear program resulted both in a carbon emission reduction similar to the Toronto Conference target, and in a significant improvement of economic performances. 4 refs.; 10 figs.; 1 tab

    Between the end of the second world war and the collapse of the Berlin wall, the French diplomacy was based on the nuclear policy in a solid and coherent way. This nuclear policy was an 'incarnation' of the national security conception, allowing France to recover its political, military and economical rank on the international scene. The most important characteristic of the French nuclear policy concerns the commercialization of the nuclear energy which aims to ensuring the national security through the building up of a financial, technological and political 'reserve'. In front of the domination of the USA and USSR during the cold war era, NE Asia had a similar geostrategic configuration as Western Europe. It concerns in particular the massive application of nuclear energy for both military and industrial purposes. The bases of the security policy in this region refers to the real use of the nuclear weapon by the USA against Japan in 1945. The French nuclear policy may be considered as a model for the building of the security policy of NE Asia, in particular through the commercialization of the nuclear technology between the countries in concern. This nuclear approach would allow the countries of these region to change their present day national defense policy into an economical and military cooperation. (J.S.)

    French research on high level waste processing has led to the development of industrial vitrification facilities. Borosilicate glass is still being investigated for its long-term storage properties, since it is itself a component of the containment system. The other constituents of this system, the engineered barriers, are also being actively investigated. The geological barrier is now being assessed using a methodology applicable to various types of geological formations, and final site qualification should be possible before the end of 1992

    1997-01-01

    In the framework of a continuous and iterative process, the French Safety Authority asks the utility EDF to implement equipment and procedure modifications on the operating reactors, in order to cope with the most likely Severe Accident sequences. As a result of Probabilistic Safety Assessments published in 1990, important equipment and procedure modifications are being implemented on the French PWRs to improve the safety in shutdown states. The implementation of another set of modifications against some reactivity accident sequences is also in progress. More recently, the Safety Authority expressed specific Severe Accident requirements in terms of instrumentation, equipment qualification, high pressure core melt accidents and hydrogen risk prevention. In that respect, EDF was asked to implement hydrogen recombiners on its reactors. On the other hand, the French Safety authority is involved with its German counterpart in the assessment process of the European Pressurized Water Reactor Project. In consistency with the common recommendations of the Safety Authorities involved, Severe Accident provisions for this reactor are being taken into account at the design stage

    An independent think-tank gives its meaning on the future of nuclear energy and on the assets of the French nuclear industry to obtain contracts and tenders in international markets. Nuclear power appears to be a necessary passage for a quick transition towards a no-carbon emitting power production. Between 2006 and 2015 the construction of about 80 reactors was launched and IAEA expects a growth rate of nuclear power production somewhere between +50 and +100% by 2030. 6 countries: United States, Russia, France, Japan, China and South-Korea have developed a nuclear industry and are able to export reactor technology. Concerning reactor construction, France's share of the world market is about 10% and France ranks third behind Russia (33%) and American-Japanese companies (33%). China will be soon a reactor supplier. On the nuclear fuel business, AREVA is also a major player. At the world scale only a few companies operate in the reactor construction field because of technological, industrial but also regulation challenges. The Hinkley Point C project is crucial for the French nuclear industry because of the attractiveness of the contract and mainly because it is an opportunity to show the ability of the French nuclear enterprises to end projects on time and it may be considered a reference to win other export contracts.

    In France, 27% of the electricity is to be produced by renewable resources by 2020. This share is intended to grow up to 2050. The recent European agreement and the French 'energy transition law' will promote such a development. The French power system is characterized by high nuclear penetration and nuclear power is meant to remain a significant contributor in the medium and long term, as a low-carbon power source. More than half the French nuclear power fleet was installed in the late seventies / early eighties. Thus, the issue of its replacement is at the core of the French power mix issue. The objective of this paper is to provide some insights about the opportunity it enables for the energy mix. Two plausible replacement scenarios are developed and analyzed as regards to the energy cost provided by nuclear power. For a given target level of nuclear installed capacities, the penetration of non-dispatchable renewable energies with dispatch priority will increase the need for nuclear power modulation at reduced average load factor. The impact of modulation on the nuclear levelized cost of electricity is assessed, according to the considered replacement scenario and for different renewable and nuclear energy penetration scenarios. Results show that, according to the selected assumptions, implementing a progressive shut-down (based on an increased operation lifetime of Nuclear Power Plants) appears a relevant choice since it both provides a lowest power production cost even at reduced average load factor to participate to load following and allows the possibility of 'waiting' for choosing most sustainable technologies.

  12. The making of French nuclear energy policy. Through the relationship between civilian and military use

    International Nuclear Information System (INIS)

    Kimura, Kenji

    2013-01-01

    The French history of nuclear development clearly shows the inseparability of its civilian use from military use. In France, Commissariat a l'Energie Atomique (CEA) and Electricite de France (EDF) have played an important role in research and development of nuclear technology since the postwar period. At first, the two organizations had kept great autonomy, but the government reinforced its control on them because France needed nuclear deterrence against the Soviet Union. France began using plutonium in 1952, and the Suez crisis in 1956 showed the need for nuclear force to ensure its independence. After this event, France managed the first nuclear test using plutonium in 1960. As for enriched uranium, they have long had great difficulty in securing it. The uranium enrichment technology became crucial also in civilian use in this period. EDF proposed the pressurized water reactor (PWR), which requires enriched uranium, as the future reactor type because of its economic advantage, but CEA wanted to continue developing the gas-cooled reactor (GCR) because of its independence in nuclear fuel supply. Finally, they chose PWR because a French enrichment facility was built in 1967. From such French history, we can say that the civilian and military use of nuclear technology are inseparable.

    Generally right candidates consider nuclear energy as a chance for France because it is an industrial asset for the country, it releases no greenhouse gases and has given France its large energy independence. They are ready to reconsider the limitation imposed on the share of nuclear energy in the future energy mix and they want to reinforce research for next generations of reactors. The far-right candidate wishes to use nuclear energy massively to produce hydrogen in order to reduce by half the consumption of fossil energies in 20 years. Generally left candidates back the law on the energy transition that was passed during last legislature and that limits the nuclear power share to 50% while developing green energies. The far-left candidates wish a progressive and complete abandon of nuclear energy. All candidates wish a greater share of renewable energies in the future energy mix. (A.C.)

    At the end of the century, neither classic resources nor so-called ''new'' energies will be able to satisfy France's energetical needs. According to this statement -and taking into account the progressive reduction of the world petroleum resources -it is estimated that industrialized countries have no other choice than developping nuclear energy. What could be then the consequences for France of such an important option. Strengthening of its energetical independence, saving in foreign currencies and a lowering of its financial load, for the ''nuclear'' KWh is about twice cheaper than the ''classic'' one. Beyond arguments often justified but sometimes also unreasoned feeding the discussion about nuclear option validity it is considered that the real choice to which France is confronted is either to have ressort to nuclear energy - with all the unavoidable problems it raises but having nothing to do with the dismaying descriptions having been made - or to endanger seriously its economic and social development [fr

  1. New French guide for the protection of nuclear facilities against external flooding

    International Nuclear Information System (INIS)

    Duluc, Claire-Marie; Bardet, Lise; Guimier, Laurent; Rebour, Vincent

    2014-01-01

    On 27 December 1999, more than ten years before the tsunami of 11 March 2011, a severe storm occurred in the vicinity of the 'Le Blayais' Nuclear Power Plant (NPP) located in the Gironde estuary. This partial flooding called into question the design bases defined in the French Basic Safety Rule (BSR) I.2.e for the protection of French NPPs against external flooding. Following an initial improvement of protections of nuclear installations against external flooding, the French Nuclear Safety Authority (ASN) and the Institute for Radioprotection and Nuclear Safety (IRSN) initiated the elaboration a new safety rule for the protection of nuclear facilities against external flooding. In order to prepare the technical basis of the new safety rule, IRSN conducted a hydrologic working group. This technical group gathered experts from universities or research organisms, government departments or agencies and operators. After a long process, the guide for protection of basic nuclear installations against external flooding was published by the French Nuclear Safety Authority in April, 2013. The purpose of this guide is to i) define the situations to consider when evaluating the flood hazard for a given site ii) propose an acceptable method of quantifying them, iii) list recommendations for defining means of protection adapted to the specificities of the hazard of flooding. A specificity of external flooding is that many different sources have to be considered. Consequently, a list of 11 'Reference Flood Situation' (RFS) is defined. Each of them is based on a single event or on a conjunction of events whose characteristics may be increased if necessary. The RFS are defined with a probability target of 10-4 per year, taking into account uncertainties.

    1989-01-01

    Among the various techniques to minimize corrosion products deposition on out of core areas, surface polishing has been researched. The attention of French partners was drawn to this technique and a test was conducted at Chinon B1 NPP in 1984 using six manway covers with various surface finishing (mechanical polishing, electropolishing, mechanical plus electropolishing/on reference). On the basis of the good results obtained and with beneficial cost considerations the electropolishing of SGCH has been decided for new EDF reactors. Once the decision was made feasibility and qualifications programs were developed. Taking into account the promising results obtained, EDF asked FRAMATOME to perform the first electropolishing operation on one steam generator channel head at Nogent 1 in 1987. Since 1988 the French experience consists of the electropolishing of 4SG at Nogent 2, 4SG at Cattenom 3, 4SG at Penly 1 and 4SG at Golfech 1 (NPP), and is perfectly satisfactory. The industrial operation provides excellent polishing and does not create undesired effects. The French partners are now thinking of a new device which could be realised at FRAMATOME especially for steam generator replacement. (author)

  7. The nuclear debate in France: some additional data. A point of view by the French Nuclear Energy Society (SFEN)

    International Nuclear Information System (INIS)

    2011-01-01

    Coming after the Fukushima accident which boosted the debate on nuclear energy in France, this document expresses the opinion of the French Nuclear Energy Society (SFEN). According to it, nuclear energy is an answer to the two main current challenges the World is facing: energy supply and global warming. Perspectives of energy policy should be based on a triptych: energy savings, renewable energies and nuclear energy. The authors also states that uranium reserves are available for centuries and even more, that the nuclear industry has a better record than other sources of production of electricity in terms of safety, and that the problem of nuclear wastes is solved. They consider that, provided that AREVA possesses property rights on important uranium reserves in America, Africa and Asia, the national independence is therefore guaranteed. Moreover, the French nuclear industry is a world leader, and the existence of nuclear energy production in France avoids many expenses. Therefore, the authors assert that giving up nuclear energy would be a triple step backwards

  8. Taking into account chemical safety for French basic nuclear installations

    International Nuclear Information System (INIS)

    Tabard, Laurence; Conte, Dorothee

    2013-01-01

    Among nuclear installations, some fuel cycle facilities present a high level of chemical hazards. In France, the TSN law of the 13 June 2006 requires taking into account all the risks generated by a basic nuclear installation (BNI). But, as most of the implementing regulatory texts are under development at this time, part of the previous regulation settled down in the 1990's is still applying: the order of the 31 December 1999 concerning technical regulation in order to prevent and to limit hazards generated by nuclear facilities; the decree of the 4 May 1995 and the order of the 26 November 1999 that deal with BNI discharges. Moreover, some parts of BNI or of nuclear sites can be submitted to the general regulation concerning chemical hazards, which is part of the environment code. As a result, even if the TSN law and its implementing decree Nr 2007-1557 of the 2 November 2007 settle clearly that safety of BNI is not only radiological, but must take into account chemical hazards, the latter aspects are still under development. Moreover the application of the existing regulation, even if complex, has helped to assess chemical risks inside BNI and nuclear sites. (authors)

    The Nuclear Safety Authority (ASN) is officially responsible for controlling safety and radioactivity in France so as to protect wage-earners, patients, the public and the environment from nuclear-related risks. It draws on the work done by the Institute of Radioprotection and Nuclear Safety (IRSN), and provides information to the public on these questions. The Authority's goal is to ensure an effective, legitimate, impartial and creditable control recognized by the public and serving as an international reference mark. ASN is led by a board of 5 commissaries, has a staff of 420 employees most of them civil servants, has an annual budget of 50 million euros and relies on 11 regional departments

    2012-01-01

    A first article comments the consequences of the Fukushima accident for the French nuclear sector: the risk of an extreme accident must be taken into account; this will result in works and investments; the cost of the French nuclear-based electricity will increase; the debate on the dismantling costs will be on again. Despite these problems, the French nuclear industry relies on its development perspectives abroad, notably in China. In an interview, the chairman of Areva discusses his first six months of action, evokes the implementation of the strategic action plan and the consequences of France's financial degradation, evokes the UraMin affair, the consequences of the Fukushima accident on Areva's offer, the costs of works required by the ASN, the perspectives for the EPR reactor, Areva's activities in the renewable energy sector. A last article comments the strategy of the German company Siemens who decided to phase out nuclear, and to focus notably of wind energy

    The PWR units of the EDF generation capacity in operation are young. They represent a technical and financial asset with a strategic significance both for the company and for France. According to regulations, even if the safety reports take into account a 40-year lifetime for the NSSS, the French regulations do not specify a time limit for the operation of the facilities according to the plant authorization decree. The Safety Authorities may, at any time require another safety re-examination. In fact, it was decided to carry out unit safety periodic reviews according to types of series. A program was set up in order to achieve regular assessments on the aging of the facilities. This program, combining all the skills within EDF and the manufacturers, is a guarantee for the coherence and the exhaustivity of the consideration as it relies on a great number of evaluation areas. It seems to day that under operational conditions, an appropriate surveillance and maintenance of components the 900 and 1300 MWe units should be able to fulfill the expected duty for a 40-year design life and very likely even longer.

    CEA is a French government-funded technological research organization. It has to build a medium-level waste interim storage facility because the geological repository will not be available until 2025. This interim storage facility, called DIADEM, has to be available in 2017. These wastes are coming from the research facilities for spent fuel reprocessing and the dismantling of the most radioactive parts of nuclear facilities. The CEA handles the waste management by inventorying the needs and updating them regularly. The conception of the facility is mainly based on this inventory. It provides quantity and characteristics of wastes and it gives the production schedule until 2035. Beyond mass and volume, main characteristics of these radioactive wastes are chemical nature, radioisotopes, radioactivity, radiation dose, the heat emitted, corrosive or explosive gas production, etc. These characteristics provide information to study the repository safety. DIADEM mainly consists of a concrete cell, isolated from the outside, wherein stainless steel welded containers are stored, stacked in a vertical position in the racks. DIADEM is scheduled to store three types of 8 mm-thick, stainless steel cylindrical containers with an outside diameter 498 mm and height from 620 to 2120 mm. DIADEM will be a basic nuclear installation (INB in French) because of overall activity of radioactive substances stored. The creation of a French basic nuclear installation is subject to authorization according to the French law No. 2006-686 of 13 June 2006 on Transparency and Security in the Nuclear Field. The authorization takes into account the technical and financial capacities of the licensee which must allow him to conduct his project in compliance with these interests, especially to cover the costs of decommissioning the installation and conduct remediation work, and to monitor and maintain its location site or, for radioactive waste disposal installations, to cover the definitive shut

    An allegedly secret report by the inspector general for nuclear safety, of EDF, has recently been unearthed and published by the French weekly 'Le Canard Enchaine, and the response in France, and very soon after also in West Germany, has been a number of alarming reports and articles in the press. Readers in West Germany have been stirred up by press reports that made French nuclear power plants appear to be a herd of hazards, which of course again added fuel to the feeling of fear of nuclear power already existing in the population. A copy of the internal report in question was sent without any fuss upon request by the atw editorial office who was preparing the interview. The report is a sober account of the state and operating behaviour of French nuclear power plants, also stating weak points seen by the safety expert that need particular attention. Materials are a main aspect in this context, particularly the materials behaviour in steam raising units. The problems have been spotted, and are given due attention. (orig./HP).

    Published 8 months after the Fukushima Dai-ichi accident, this special issue of Le Monde newspaper takes stock of the nuclear question. Prior to the Fukushima accident, the civil nuclear industry experienced two other major accidents: Three Miles Island (US, 1979) with limited and controlled impacts, and Chernobyl (USSR, 1986) with enormous impacts. The recent Japanese catastrophe has revived the questions concerning this risky technology. However, according to the IAEA, the civil nuclear energy should continue to develop in the future but in a more moderate way. Germany announced in June 2011 the shutdown of its last reactor by 2022, while France remained an exception until the Fukushima accident with a large political consensus among the general public in favor of nuclear energy. The nuclear phasing out or the energy transition is a complex question which is explored in this special issue. Content: 1 - The nuclear world: a moderate growth of the nuclear industry; interview of Mohamed ElBaradei, former head of IAEA; 441 reactors in operation in the world in January 2011; France has chosen the all-nuclear option; critics: a 'costly, unadapted, useless' nuclear program; interview of Valery Giscard d'Estaing, former French President; the nuclear industry actors; nuclear dismantling: a what cost?; how to manage the 250.000 tons of spent fuels; 2 - A risky technology: radioactivity measurement and effects; how to manage contaminations; four generations of reactors; ITER: a solar project; imagining the unimaginable and anticipating the worse; the wake up of a dozed off fear; the most important accidents: the progress of the three main nuclear catastrophes, the human mistake of Three Mile Island, the days after the Chernobyl accident, in the dead cities around Fukushima; interview of Kenzaburo Oe (Japanese writer); the Blayais power plant to the test; 3 - The energy transition: is France capable to abandon nuclear energy?; Germany is going to re-launch gas- and coal

    1964-01-01

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

    A nuclear program can be compared to a pastry. There are many ingredients, a lot of know-how, an adequate cooking and some good luck to achieve success or back luck to fail. The French nuclear program has had all the ingredients of success and the necessary luck. The present paper presents the major ingredients: strong and well defined policies, an adapted industrial organization, original management methods, dedicated men, political and popular support. The main results of the French program, well known today, are only briefly be presented. The last part of the paper show the very strong interactions between operation and design, and how experience is fed back into the design both of new and of older plants. The conclusion calls for new ingredients for future success

The objective of this study was to supply an additional information before the laying down in 2006 of the decisions about the management of high-level and long-lived radioactive wastes. This inquiry, carried out between April 2004 and March 2005, stresses on the knowledge and doubts of the questioned people, on the vision they have of radioactive wastes and of their hazards, and on their opinion about the actors in concern (experts, nuclear companies, government, anti-nuclear groups, public). The last two parts of the report consider the different ways of waste management under study today, and the differences between the opinion of people living close to the Bure site and the opinion of people living in other regions.

    The French electricity supply system is based on nuclear energy, with three quarters of total electricity production originating from nuclear power plants. The sector has grown continuously over a period of 60 years. For a long time the realms of politics and science were in consensus about the use of nuclear energy for civil purposes, but now the French nuclear dogma is increasingly being called into question as a result of the disaster in Fukushima, the German decision to phase out nuclear energy and European energy policy in general. How will France shape its future energy policy given these altered framework conditions?.

    In 2005, at the request of the French Government, the Nuclear Safety Authority (ASN) established a Steering Committee for the Management of the Post-Accident Phase of a Nuclear Accident or a Radiological Emergency, with the objective of establishing a policy framework. Under the supervision of ASN, this Committee, involving several tens of experts from different backgrounds (e.g. relevant ministerial offices, expert agencies, local information commissions around nuclear installations, non-governmental organisations, elected officials, licensees, and international experts), developed a number of recommendations over a 7-year period. First published in November 2012, these recommendations cover the immediate post-emergency situation, and the transition and longer-term periods of the post-accident phase in the case of medium-scale nuclear accidents causing short-term radioactive release (less than 24 h) that might occur at French nuclear facilities. They also apply to actions to be undertaken in the event of accidents during the transportation of radioactive materials. These recommendations are an important first step in preparation for the management of a post-accident situation in France in the case of a nuclear accident. © The Chartered Institution of Building Services Engineers 2014.

    The layouts of the control rooms of the French nuclear power stations have undergone great development in the period 1970-1990. The control rooms, with an architecture similar to that of the oil fired power stations, were similar to those of the 1300 MW blocks in which the human factor was emphasised. For the selection of a computerised control room for the N4 series, comprehensive functional and ergonomical validation on a full simulator was required. (author) 3 figs., 7 refs

    2017-09-01

    Whereas the French Energy Multi-year Programming (PPE) notably aims at preserving the purchasing power of consumers and the competitiveness of energy prices, this note aims at reporting an assessment of the production cost of the French present nuclear fleet, i.e. the electric power cost at the output of the production installation. The authors first discuss the choice for the methodology of 'cash costs' for the decision to continue of not the exploitation of existing units. They propose a mean assessment of about 33 euro/MWh, state that the present nuclear-based power production in France is profitable, and consider that there is no 'investment wall' to be faced in the near future. They also state that nuclear costs are hardly supposed to increase because they are little sensitive to uranium prices. They consider that dismantling and waste costs are covered at more than 100 per cent by dedicated assets. A technical note comes with this discussion. It discusses cost calculation methods, the assessment of the production cost of French existing reactors (second generation), and some additional elements regarding some cost components

  10. Physical protection concepts of nuclear materials. The French experience

    International Nuclear Information System (INIS)

    Arnaud, G.; Artaud, R.

    1995-01-01

    As the nuclear energy was being developed, it appeared necessary to set up protections against its potential hazards, that should be more complete and elaborate than those implemented on the other industrial installations. This had to be done both in the safety field to prevent the environment and the populations from the consequences of severe casualties, and in the security field to avoid the risk of proliferation and limit to an acceptable level the results of voluntarily provoked accidents and sabotages. Taking advantage of the gathered experience, this document gives consideration to the concepts used in France in order to ensure the physical protection of the nuclear materials. The following topics are tackled: context inside which are envisaged the specific measures, coherence with the general dispositions taken to protect industrial installations, importance and limitations of the part played by the regulations, respective responsibilities of the plant operators and the public authorities, compromise between objectives in view and means to implement, adjustment between the physical protection system and the operating requirements. In addition, the ways in which these systems should be implemented are discussed, underlining the necessity to make progressive steps under a permanent will, in order, first, to update and bring under conformity the old installations, and second, to ensure the maintenance of the systems, taking account of the evolutions of needs and techniques. Those points are commented on examples taken among the different types of installations to be found in France, showing the differences in approach coming from the type and the age of the facilities, and giving the present trends for the new plants.

    1986-01-01

    The fact that users of nuclear boilers of proved types are no longer troubled by the mechanical structure behaviour of reactors is due to the sustained efforts of construction engineers during the past ten or twenty years to perfect, and incorporate in their equipment studies, the latest developments which have emerged from the expert engineering community of the world, which you represent here today. The presentation is divided into five parts. Firstly, two parts will be devoted to showing how and why the past twenty years have enabled us to achieve our present results which can objectively be regarded as excellent. Thirdly, it is explained why we believe that it is reasonable to assume that our power stations will have an effective life of up to 40 years. In the fourth part I shall revert to more immediate preoccupations and tackle the subject of the desirable optimisation of in service inspection programmes in the light of what we have learnt from modern design studies.

    As early as the beginning of its nuclear program, France has developed a wide range of higher education programs and occupational training in nuclear sciences, nuclear technologies and nuclear engineering. INSTN (Institute for Nuclear Sciences and Nuclear Technologies) was founded in 1956 inside CEA premises at Saclay to issue the diploma of 'ingenieur en genie atomique'. This diploma is still delivered and celebrated its 60. anniversary in 2016. A large course offering has been added to the sole initial INSTN diploma. Throughout France and each year about 2000 students are awarded a diploma opening the gates of nuclear industry or research from vocational baccalaureates (130) to doctoral thesis (200) via engineer/master degrees (1270). Continuous training has also been developed, employees from the nuclear industry benefit from 16 days a year of training in average. French high education systems are open to foreign students and 9 master degrees in nuclear engineering are entirely taught in English. (A.C.)

    The CEA Cadarache research center is one of the 10 research centers of the French Alternative Energies and Atomic Energy Commission (CEA). Distributed throughout various research platforms, it focuses on nuclear fission, nuclear fusion, new energy technologies (hydrogen, solar, biomass) and fundamental research in the field of vegetal biology. It is the most important technological research and development centers for energy in Europe. Considering the sensitive nature of nuclear activities, the questions surrounding the issue of radioactive waste, the nuclear energy and the social, economic and environmental concerns for present and future generations, the French Government asked nuclear actors to open communication and to give all the information asked by the Local Information Commission (CLI) and the public [1]. In this context, the CEA Cadarache has decided to better show and explain its expertise and experience in the area of nuclear energy and nuclear power plant design, and to make it available to stakeholders and to the public. CEA Cadarache receives each year more than 9000 visitors. To complete technical visits of the research facilities and laboratories, a scientific cultural center has been built in 2011 to inform the public on CEA Cadarache research activities and to facilitate the acceptance of nuclear energy in a way suited to the level of knowledge of the visitors. A modern interactive exhibition of 150 m{sup 2} allows visitors to find out more about energy, CEA Cadarache research programs, radioactive waste management and radiological impact on the research center activities. It also offers an auditorium for group discussions and for school groups to discover science through enjoyment. This communication center has received several thousand visitors since its opening on October 2011; the initial results of this experience are now available.

    This document comprises two reports. A first one, published and updated three times a year, and a second one which is a yearly publication. The first one, based on an analysis of market perspectives and of actor strategies, proposes a synthesis on the consequences of the evolution of the economic environment, on major trends noticed for the nuclear sector, and on predictable evolutions. It proposes the most recent data regarding the activities of more than 100 firms belonging to the sector (notably in terms of electric power production, of turnover for firms specialised in nuclear maintenance or in the fuel cycle). It highlights recent events for companies of the sector: takeovers, investments, restructuring, introduction of new products, and so on. It proposes a sector-based dashboard which contains all the critical figures useful to analyse the sector situation (activity determining factors, key figures for the sector and its environment). The annual report proposes a general presentation of the sector (determining factors of the activity, operated nuclear plants in the world, nuclear power production in the world, uranium production and consumption in the world, maintenance and improvement expenses on nuclear plants, electric power consumption and shares in power generation by different sources in France), an analysis of the evolution of the sector activity (trends, indicators, financial performance of actors in the maintenance of nuclear plants), an overview of important issues for the profession (growth issue despite the maturity of the French market, implications of intensification of foreign competition, of higher safety requirements, and of a decrease of nuclear energy profitability), and an analysis of the sector economic structure (turnovers, personnel, position of France among world exporters, equipment export structure, key figures for nuclear maintenance). The last part proposes presentations of 20 French actors and data and information sheets for 10

    The complementary features of low-carbon power sources are a central issue in designing energy transition policies. The French current electricity mix is characterised by a high share of nuclear power which equalled 76% of the total electric production in 2015. With the increase in intermittent renewable sources, nuclear flexibility is examined as part of the solution to balance electricity supply and demand. Our proposed methodology involves designing scenarios with nuclear and intermittent renewable penetration levels, and developing residual load duration curves in each case. The load modulation impact on the nuclear production cost is estimated. This article shows to which extent the nuclear annual energy production will decrease with high shares of intermittent renewables (down to load factors of 40% for proactive assumptions). However, the production cost increase could be compensated by progressively replacing the plants. Moreover, incentives are necessary if nuclear is to compete with combined-cycle gas turbines as its alternative back-up option. In order to reconcile the social planner with plant operator goals, the solution could be to find new outlets rather than reducing nuclear load factors. Nuclear flexibility could then be considered in terms of using its power to produce heat or hydrogen. - Highlights: •Nuclear flexibility is examined to balance the system with high renewables share. •Impacts of wind and solar shares on the nuclear load factor and LCOE are assessed. •Nuclear fleet replacement must be progressive to ensure competitive load-following. •Incentives are needed for nuclear to compete with CCGT gas back-up. •We recommend considering nuclear flexibility through the power use.

  20. French codes and standards for design, construction and in-service inspection of nuclear power plants

    International Nuclear Information System (INIS)

    Hugot, G.; Grandemange, J. M.

    1995-01-01

    In 1970, France decided that its future power plants would be of the Pressurized Water Reactor type. This choice proved to be successful since it resulted in more than 60 PWR units in operation or under construction in France and abroad. At the beginning of such a program, the French engineering and manufacturing industry, the national electrical utility and the Safety Authorities had to face the many challenges imposed by the implementation of an imported technology. The government reorganised the licensing process. FRAMATOME, the NSSS vendor, and EDF (Electricite de France), the national utility, decided to create 'AFCEN', the French Association for Design and Construction Rules for Nuclear Island Components. These rules, the RCC's (Regles de Construction et de conception), which are approved by French Safety Authorities deal with mechanical and electrical equipment as well as with nuclear fuel and civil works. They are now being supplemented by in service inspection rules, the RSE's (Regles d'inspection en Service). The paper presents these Codes and their main updating following experience of application, technical progress and evolution of standards. Status of discussion concerning reference to European standardisation and developments of rules applicable to the EPR project will also be discussed

    1983-01-01

    More than 1000 microprocessors and more than 10,000 data memories in each of the twenty or so 1300 MW units in the French nuclear programme: that was the decision taken by Electricite de France (EDF) in conjunction with the designers in 1974, with the intention of introducing programmable automata on a wide scale in French nuclear power plants. This programme was carried out with the assistance of advanced research services such as the universities, the Commissariat a l'energie atomique (CEA), EDF's design and research service and the designers, most of whom were already EDF suppliers for the 900 MW range. Having used computers for linking sequences (themselves carried out with electromagnetic technology) for its latest natural-uranium gas-cooled graphite-moderated power plants, EDF decided to call a temporary halt, in the case of its 900 MW light-water range, to the use of digital techniques for the control and automation of power plants although it continued to employ such techniques widely in data processing. Thus, the widespread introduction of programmable automata, which was decided upon in 1974/75 at a time when no equivalent existed at the international level, led EDF and French designers to undertake a major development effort in order to meet the requirements - particularly safety and reliability requirements - for such automata to be incorporated into the nuclear field. How does this choice fit in with the logical evolution of the digitalization of French nuclear power plants. What problems has it caused for EDF and French industry. How have these problems been tackled. How have they been overcome. These are the questions dealt with in this paper. (author)

  2. French diagnostic reference levels in diagnostic radiology, computed tomography and nuclear medicine: 2004-2008 Review

    2013-01-01

    After 5 y of collecting data on diagnostic reference levels (DRLs), the Nuclear Safety and Radiation Protection French Inst. (IRSN) presents the analyses of this data. The analyses of the collected data for radiology, computed tomography (CT) and nuclear medicine allow IRSN to estimate the level of regulatory application by health professionals and the representativeness of current DRL in terms of relevant examinations, dosimetric quantities, numerical values and patient morphologies. Since 2004, the involvement of professionals has highly increased, especially in nuclear medicine, followed by CT and then by radiology. Analyses show some discordance between regulatory examinations and clinical practice. Some of the dosimetric quantities used for the DRL setting are insufficient or not relevant enough, and some numerical values should also be reviewed. On the basis of these findings, IRSN formulates recommendations to update regulatory DRL with current and relevant examination lists, dosimetric quantities and numerical values. (authors)

  3. Revisiting the cost escalation curse of nuclear power. New lessons from the French experience

    Since the first wave of nuclear reactors in 1970 to the construction of Generation III+ reactors in Finland and France in 2005 and 2007 respectively, nuclear power seems to be doomed to a cost escalation curse. In this paper we reexamine this issue for the French nuclear power fleet. Using the construction costs from the Cour des Comptes report, that was publicly available in 2012, we found that previous studies overestimated the cost escalation. Although, it is undeniable that the scale-up ended up in more costly reactors, we found evidence of a learning curve within the same size and type of reactors. This result confirms that standardization is a good direction to look, in order to overcome the cost escalation curse. (authors)

  4. The perception of nuclear risks on French sites: social actors and rumors

    1983-01-01

    This study summarizes the main French researchs on people living close to nuclear plants and their perception of nuclear risks. The ethnological approach was utilized, consisting in an observer living long periods of time on the site. It shows the existence of a ''psychogeographical'' zone in which people fell concerned by the building of the plant. This event reinforce the existing tensions between the social actors in the field of the site. The plant is seen as a ''big work'' ''eating'' land from agriculture and recreation, mixed with a nuclear thing mysterious and dangerous. Perceptions and rumors are greatly varying depending time and space. These results may be applied to a better siting of the plants [fr

    A number of problems present themselves for any scholar seeking to take into account all determinants relating to 'national' and 'international' action in the analysis of foreign policy. In the domain of the French diplomatic practices of the mid-1970's-structured around the apparent issue of nuclear exports-archival consultation and interviews reveal that the various actors involved in this policy were not necessarily playing the same national and international 'double game.' While relations between states shape what they are and do, the various effects of refraction at work at the internal level prevents one from speaking of a state taken uniformly across a space of competition

    The explicative dictionary for nuclear power, accomplished in the frame of the Commission for Scientific Terminology of the Romanian Academy, represents the second issue in a series running from Nuclear Energy EN 1 through Nuclear Energy EN 10 covering the following fields: EN 1. General terminology; EN 2. Nuclear power; EN 3. Physical protection and nuclear safeguards; EN 4. Nuclear fuel cycle; EN 5. Radioactive wastes; EN 6. Safety of nuclear facilities and materials; EN 7. Radioprotection and dosimetry; EN 8. Nuclear reactors; EN 9. Nuclear sciences and engineering; EN 10. Nuclear law and legislation. The main body of the dictionary's contents was selected by specialists working with the Center of Technology and Engineering for Nuclear Projects - CITON, based on their experience of more than 20 years in introducing and implementing nuclear power in Romania, as well as, on collaboration with nuclear physics and engineering research institutes and physics departments of Romanian universities. The project of a nuclear dictionary in 10 issues aims at supporting the program of nuclear power development in Romania and is at the same time part of nuclear knowledge management policy boosted by IAEA which encourages publication of informative materials highly specialized but also accessible to the public at large. The project aims also to establish the Romanian standardized terminology in the nuclear domain as much in line as possible with the terminologies of the largest communities worldwide most active in nuclear science and technology. Under the guidance of continuos build-up and evolution of nuclear knowledge the present work is intended to be upgraded permanently. The explanation of the terms was based on SR ISO standards, terminology adopted by Organization for Economic and Cooperation Development, OECD/NEA, and IAEA. This series is targeting translators, specialists, students, and the public at large

  9. Objective and Essential Elements of a State's Nuclear Security Regime. Nuclear Security Fundamentals (French Edition)

    International Nuclear Information System (INIS)

    2014-01-01

    The possibility that nuclear material or other radioactive material could be used for criminal purposes or intentionally used in an unauthorized manner cannot be ruled out in the current global situation. States have responded to this risk by engaging in a collective commitment to strengthen the protection and control of such material and to respond effectively to nuclear security events. States have agreed to strengthen existing instruments and have established new international legal instruments to enhance nuclear security worldwide. Nuclear security is fundamental in the management of nuclear technologies and in applications where nuclear material or other radioactive material is used or transported. Through its nuclear security programme, the IAEA supports States to establish, maintain and sustain an effective nuclear security regime. The IAEA has adopted a comprehensive approach to nuclear security. This recognizes that an effective national nuclear security regime builds on: the implementation of relevant international legal instruments; information protection; physical protection; material accounting and control; detection of and response to trafficking in such material; national response plans; and contingency measures. With its Nuclear Security Series, the IAEA aims to assist States in implementing and sustaining such a regime in a coherent and integrated manner. The IAEA Nuclear Security Series comprises: Nuclear Security Fundamentals, which include the objective and essential elements of a State's nuclear security regime; Recommendations; Implementing Guides; and Technical Guidance. Each State carries the full responsibility for nuclear security. Specifically, each State has the responsibility to provide for the security of nuclear material and other radioactive material and their associated facilities and activities; to ensure the security of such material in use, storage, or in transport; to combat illicit trafficking and the inadvertent movement of

    Levret, A.

    1987-11-01

    Since 1975 in order to be in conformity with the requirements of the French nuclear program, a review of historical seismicity was undertaken in France. The assessment of seismic hazard for the safety of nuclear plants is in fact based upon a seismotectonic approach which needs to take into account the seismic activity over as long a period of time as possible. The method adopted for reviewing historical earthquakes entails a systematic consultation of the original sources and a critical analysis there of in the light of the historical, geographical and political contexts of the time. The same standards apply where the acquisition of new elements of information is involved. Each item of information is assigned a degree of reliability, then compiled in a computer file, up-dated annually; this file currently contains more than 4.500 events covering a period of time of about a millenary

    The decision taken the day following the end of the second world war to create a French industry for the nuclear fuel cycle, the speed and dimension of its development from 1946 to 1966, the strengthening of its acquired knowledge during the following five years, lastly, the fact that, since 1972, it was able to make great strides, will have been in short the fruit of the remarkable continuity of an unfailing political will. Consequently it was possible beyond doubt, as soon as the ineluctable consequences of the oil crisis were evaluated, to give the French nuclear fuel cycle industry the new objectives which will succeed in granting it a foremost dimension on the international scale. In the three branches constituting the base of this industry (natural, enrichment, reprocessing), all these objectives will be reached by 1985. Their realization will permit our country to cover, in all security, not only its domestic needs but also to pursue a policy to sell materials and services for export at competitive prices [fr

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

    International Nuclear Information System (INIS)

    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.

  14. Proposition of law relative to the sanitary follow up of French nuclear tests

    International Nuclear Information System (INIS)

    2008-03-01

    The present proposition of law has for object to answer the expectation of all the persons who have participated as military personnel or civilians in nuclear tests made by France between February 13., 1960 and January 27., 1996, or lived near the nuclear test sites of Sahara (Reggane) or in French Polynesia. The same pathologies are noticed among the veteran or the populations having lived near the nuclear tests sites of the other nuclear countries which made the same experiments. It is the case in United States, in Great Britain, in Australia, in New Zealand and in Fidgi. In these different countries having a democratic system similar to ours, the governments took concrete measures to accede to the demands of their nationals. It thus turns out that a legislative initiative would represent a strong message of gratitude towards all those who had to undergo aftereffects on their health and that of their descendants of the only fact of their participation in the nuclear experiments of France.

    Tabard, Laurence; Conte, Dorothee

    2013-01-01

    The determination of discharge authorized limits for a French nuclear site is initiated by the request of the operator, based on the maximum nuclear and chemical inventory that could be released during normal operating conditions, accompanied with justifications. Request and justifications are analyzed and discussed by the ASN and the IRSN, taking into account nuclear and chemical inventories expected inside BNI, current regulations (BNI specific regulation, environment code, public health code), operating feedback (release feedback for an operating BNI, feedback coming from other nuclear sites or installations, etc.) and best available technologies that can be used to treat liquid or gaseous waste before release. After taking into account potential suggestions coming from public information or public enquiry concerning the operator request, the discharge authorized limits are settled down in specific ASN prescriptions that have to be ratified by the State secretaries in charge of nuclear safety. The whole process runs through 2 or 3 years to be achieved. Communication has revealed to be quite an uneasy task, even for administrative procedures. This aspect is mostly tested while communicating about events. Consequences of this communication can hardly be foreseen because of multiple external parameters like: news on the front pages at the same moment; historic communication difficulties still in the public mind; technical vocabulary not easily understood; public fear of things being hidden; power of ecologist or non-governmental associations.

Because of this width, even if the unavailability of the park remains on a low level on average, the experience feedback on this parameter gives very a rich lesson. The general evolution of unavailability over the last years is the subject of the first part of the talk. Several modes of analysis are examined: by year on the whole of the units, for the various series, by order of age of the various units. The different modes of gathering are examined and others are evoked, in order to reveal those which allow an optimal use of the experience feedback. The outstanding facts are then presented: the principal causes of unavailability are raised and examined. Certain equipment stand out particularly: the reasons of these singularities are exposed as well as the lesson and the modifications brought, the committed actions. Finally the applications resulting from the studies of the unplanned unavailability of the nuclear units are developed. Of course they relate in the forefront to the field of maintenance with the use of these studies within the framework of optimized and adapted programs of maintenance. The contributions are examined. The aging evolution of the plants is also analyzed starting from these studies. The stress is put however on a less obvious application: this one of the future units in design. (author)

    Full text of publication follows: Nuclear energy contributes to most than 75% of the French electricity thanks to the operation of 58 generation 2 reactors located on 19 sites built from the 70's to the end of the 90's. France also developed for a long time a fully integrated nuclear industry covering the whole nuclear fuel cycle, from the ore mining to the fabrication of the fuel for the front-end, from the reprocessing up to the MOX fuel fabrication and storage facility and in the near-future geological repository for the back-end. This investment allows France to produce a low-carbon electricity with the second lowest GHG emissions intensity, in the range of 90 g CO 2 /KWh. Such a very beneficial figure is directly related to the high contribution of nuclear in the electricity mix combined with renewables energies, in particular hydro. Greenhouse gases emissions are very relevant to assess the respective influence on the global climate change, but they do not address the whole potential environmental impact of any activity. However, such a question is crucial for assessing the respective sustainability of such an activity, in particular nuclear energy which is thought to be very detrimental by a large part of the public opinion. In order to address this question, we developed a dedicated life cycle assessment (LCA) tools referred to as NELCAS, the specificity of which is to focus on the first order parameters and avoiding any 'black-box' effect which can exist in commercial LCA tool. Thanks to the recent transparency and nuclear safety law (2006), in- and out- fluxes of matter and energy for any of the fuel cycle facilities are now publicly available. We hence used this significant set of measured data to feed our model and assess the most usual environmental indicators such as land use, different types of atmospheric emissions (GHG, SOx, NOx, particles...) and aqueous release (chemical effluents, eutrophication potential,...)...

    This paper presents a practical assessment of environmental and health impact associated with the normal operation of the different facilities within the French uranium fuel cycle. (Only the PWR's are taken into account.) Fundamentally three objectives are considered in this impact assessment: the environment, the general public and the workers. The French nuclear program projected for 1990 consists in 50 reactors (PWR), distributed on about 24 sites, and is able to satisfy a demand of 304,5 TWh. Concerning each step of the uranium fuel cycle (mine, mill, conversion, enrichment, fuel abrication, reactor, reprocessing and transportation) the following health and physical indicators are used: 1) Liquid and gaseous activities annually released from normal operation of the facility. 2) Individual whole body dose-equivalent at the site boundary. 3) Collective dose equivalent for the general public 20-50 km from the site. 4) Individual and collective occupational radiation exposures. 5) Health effects estimated over the year 1990 by application of the last ICRP's coefficients (Publication No.26). Finally an application of the environmental commitment dose concept is included for the long half-life radionuclides released. (H.K.)

    1988-01-01

    In the early eighties, and in the French case from 1985, the development of the data-processing industry has made the real integration of project-management information systems feasible, and the data-base administration function has been extended to all facets of the engineering process. The new systems had to take into account the existing ones which were still operating efficiently and the new problems encountered due to the changes in the environment. One of these new problems was equipment and materials management, as the period of plants built in series had vanished, and the industry was obliged to build plants individually. The challenge encountered by the French nuclear industry in terms of the project-management information systems was to adapt efficiently to the new situation, and the purpose of this paper is to describe the most-significant elements of this adaptation. The authors review: (2) the objectives established by the company's general management; (2) the organization put into place to reach these objectives; (3) the main choices made; and (4) the economics. 3 references, 1 figure, 1 table.

    The works presented here constitute the first systematic study of the incidence of childhood leukemia around the whole of French nuclear facilities. Globally, the incidence of childhood leukemia does not diverge significantly of the expected incidence during the period 1990-1998. It does not show a decrease of S.I.R. (standardized incidence ratio) in function of the distance from child's home to the nuclear site whatever be the age. This study represents the first analysis of the incidence of leukemia focusing on 29 French nuclear sites, including the whole of the 19 C.N.P.E. ( nuclear power plants that produce electric power), and is based on incidence data rather than mortality. The period, the age groups and the studied area have been all chosen a priori, that gives a statistical validity to the results. The estimation of population at risk have been made with several different methods of interpolation in order to check the stability of estimations. The different methods of statistical analysis used have lead to extremely close results, reinforcing our confidence in the reliability of our estimations. The excess of leukemia incidence observed at Chinon and Civaux and the deficit observed at Bruyere/Saclay/Fontenay loose their statistical significance when the correction of Bonferroni is applied. So, the global analysis of the 29 sites and the analysis by site have not shown statistically significant difference between the numbers of observed and expected cases. The study of the 19 C.N.P.E. gave same results, even in taken into account their electric power or their year of service. The possibility of confounding factors has been excluded. The power of the study to detect excess incidence and a decrease of S.I.R. with distance from the site was examined under different alternative hypotheses through simulation methods. For values of S.I.R. near the site (0-5 km) between 1.5 and 2 and a risk of error of 5%, the power of the study is between 96% and 100% depending

    Full text: Background: We conducted a mortality study on a cohort of French nuclear workers employed at Electricite de France (EDF). A first mortality analysis relied on the period 1968-1994. Present results consider an updated mortality analysis including 9 additional years of follow-up and rely on the period 1968-2003. Methods: The cohort includes 22,393 workers, 96% of them are males. Employment data were updated using Personnel EDF file. Vital status was ascertained using the French National Registry of individual identification, and further completed using EDF personnel and pension files. Causes of death were obtained through the National file of causes of death. The observed mortality was compared with national rates by indirect standardisation and expressed by Standardised Mortality Ratios (SMR). All causes, all cancers and external causes SMRs were detailed according to sex, age and calendar year. Variations according to date of entry into cohort, duration of employment and socio-economic status (SES) were studied. Comparison with the earlier follow-up is presented. Results: At the present study end point (31/12/2003), 74% of workers are still in active service. Only 0.3% of workers are lost to follow up. The total number of person-years is nearly 450,000. Causes were ascertained for 96 % of deaths. The total number of deaths is 874: 307 are cancer deaths, including 16 leukaemia. SMRs for all causes of death and all cancers show a significant deficit compared to the French national mortality. Significant variations of all causes and all cancers SMRs according to SES were observed. No significant excess compared to French national mortality was observed for any of the 30 different cancer sites studied. Borderline significant excess were observed however for pancreatic, pleural, kidney and brain cancer. SMR for leukaemia is equal to unity. Conclusion: There is a clear evidence for an effect of selection of healthy individuals into the workforce. Although 9

    Improvement of the nuclear island design, to facilitate maintenance and working conditions during plant shutdown, has been a subject of particular attention within the French PWR program. Standardization and industrial concentration created an unusually favourable context for approaching this objective. Progress efforts supported by the feedback of actual operating experience were pursued in the areas of plant layout-equipment installation, and on the design and technology of the component themselves. The progress efforts on the design and technology of the components were pursued along several paths including: - the resistance increase of specific parts submitted to various forms of in-service damage, - the reduction of the extent and duration of work during plant outages and - the reduction of the Occupational Radiation Exposure (ORE), one of the most important axes of development, through the appropriate selection of less releasing materials, the implementation of more efficient decontamination systems and by the use of robots

    The incident analyses performed in French nuclear power plants high-lighted that deficiencies in the design of procedures are frequent causes of human errors. The process for developing new guidelines for the writing of test and emergency procedures is presented: this process is based on operators interviews and observations at the plants or at simulators. The main principles for the writing of procedures are developed. For example: - the elaboration of a procedure for action and of a separate educational procedure, - the coordination of crew responses, - the choice of vocabulary, graphs, flow charts and so on as regards the format. Other complementary actions, such as the training of operators in the use of procedures, are described

    Under present French practice, assessing the effects of radioactive discharges due to the various likely accident situations comes under 'L'Analyse de Surete Nucleaire' (Nuclear Safety Analysis). The assessment of radioactive discharges relating to normal working comes within the framework of radioecologic studies. Radioecology studies are undertkaen for every power station project. They consist in: - studying what is to be done with radioelements discharged as liquids or gases, - estimating their impact on the populations in the areas of influence of the power station and checking that this impact is permissible, - establishing a surveillance measuring programme for checking against the predictions made and, if required, determining the modifications to be made to the facilities or to their method of operation [fr

  9. Qualification by analogy of the functional valving of French pressurized water nuclear power stations

    1991-01-01

    In certain postulated accidental conditions (loss of coolant accident or secondary pipe rupture, earthquake, high energy pipe rupture) plant valving is called on the important functions to bring the reactor to and maintain it at a safe shutdown condition. ELWCTRICITE DE FRANCE has completed qualification tests of about forty valves to assure their operability. However, taking into account the costs and time required to obtain this qualification and the number of valves to be qualified, this method alone is not sufficient. For this reason, Electricite de France has developed the alternative qualification methodology by analogy for each postulated accidental situation. Feedback experience of these methods today is such that it can be they have achieved their objective; namely, to improve the safety of French pressurized water nuclear power stations, while at the same time avoiding the two dangers represented by excessive complexity resulting in unsatisfactory operation, and insufficient thoroughness not providing any real increase in safety.

    The prevention of the fast fracture damage of the mechanical equipment important for the safety of nuclear islands of the French PWR relies on deterministic rules. These rules include flaw acceptance criteria involving safety factors applied to characteristic values (implicit margins) of the physical variables. The sets of safety factors that are currently under application in the industrial analyses with the agreement of the Safety Authority, are distributed across the two main physical parameters and have partly been based on a semi-probabilistic approach. After presenting the generic probabilistic pro-codification approach this paper shows its application to the evaluation of the performances of the existing regulatory flaw acceptance criteria. This application can be carried out in a realistic manner or in a more simplified one. These two approaches are applied to representative mechanical components. Their results are consistent.

    The accidents which occurred in the nuclear power plants in Fukushima-Daiichi resulted in a complementary safety assessment (CSA or stress-tests) of all French NPPs to confirm their compliance with their design bases and to evaluate their behaviour beyond it. They have shown that nuclear facilities have a satisfactory level of safety, but it had been decided to significantly improve their robustness to extreme situations, beyond the safety margins they have already. Planned improvements include several parts, where the main ones are the implementation of a hardened safety core (HSC) of key components for the management of extreme situations resulting from a hazard beyond the design and deployment of a nuclear rapid response force (FARN). The hardened safety core aims to avoid massive releases and lasting effects in the environment. It relies on existing or new components designed or verified to hazards with significant margins compared to the design levels of NPP beyond. It also includes provisions allowing crisis management, including crisis centre and communication means. The FARN complements the HSC and the crisis organization to bring from off-site sufficient human and material resources to increase the autonomy of the site. All these improvement contribute to a better defence in depth. (author)

    After recalling the entry of nuclear energy into energy production in France, the paper emphasizes the evolution of techniques applied in the designing of French nuclear power plants and describes the means employed for reducing costs per kWh of EDF2 and EDF3 compared with EDF1: the electric power per ton of uranium varies from 493 kW/t for EDF1 to 970 kW/t for EDF3. For this purpose the thermal power and electric power of units are changed respectively from 290 MWt for EDF1 to 1200 or 1600 MWt for EDF3 and from 28 to 250 MW. The results are obtained by an improvement in neutronic characteristics, developments in nuclear fuel technology, and simplification of the system of charging the reactor, whose means of maintenance are increased; the EDF2 heat-exchangers have been so designed as to increase the unit power of the elements, which will attain 9 MWt, as against 3 for EDF1. For EDF3 an advance project forecasts a thermodynamic layout with only one pressure stage. The paper ends with a description of the burst-slug detection systems, and an appendix gives a detailed comparative table of EDF1, EDF2 and EDF3 plant characteristics. (author) [fr

    After a brief presentation of the survey method (sample, survey mode, dates, error margins and confidence interval), this report presents and briefly comments the main results of a survey on perception French people have on nuclear industry and activities. More precisely, questions asked to the people addressed the following issues: the perception of nuclear as a taboo issue, words associated with nuclear, and the perception of the safety distance to be observed in case of a nuclear accident. For these three questions, tables of data are given which contain answers and social and demographic characteristics

    In April 1996 the French ministry of health took the decision to distribute iodine tablets to the population surrounding all nuclear power plants in France. In case of a severe accident the absorption of stable iodine would prevent irradiation of the thyroid by radioactive iodine released by the plant. This preventive distribution was initiated at the end of 1996 around 4 pilot sites, and then spread to all sited in 1997. During this period, the large public sample surveys conducted by IPSN for its barometer contained questions on counter-measures in case of a nuclear accident and more specifically on the distribution of iodine tablets. The aim of this polls was to find out if the general public had known about this decision and to get some feedback on its reactions. The work presented in this paper is the detailed analysis of the two sets of data obtained by the answers to the polls. Some numerical treatments and tests were performed to compare the data, evaluate their consistency and analyse the relation between the distance to a nuclear site and the perception of the public. The main conclusions are that people living close to nuclear sites knew more about the on-going action of the ministry of health, and appreciated it more than the general population but in the same time, many people (70% of interviewed people) are quite reluctant to have tablets in their home; and 65% of the population directly concerned with the distribution did not know where to get their tablets. It is now intended to follow the potential evolution of this results in year 2000 when public authorities have to organise a new distribution of iodine tablets. (author)

    In 1996, the utility operating France's nuclear power plants launched feasibility studies for the refurbishment of the nuclear instrumentation system (RPN classed category A) installed in its CPO-series (900 MWe) units. The system was ultimately upgraded with digital I and C system, using a SPINLINE 3 platform. This article describes feedback from an evaluation conducted on the refurbishment by the Institute of Radiological Protection and Nuclear Safety (IRSN), technical support arm of the Directorate General for Nuclear Safety and Radiological Protection (DGSNR). The study begins with a historical overview of the refurbishing operation, then discusses the IRSN assessment method and the lessons learned from this first major revamp of an I and C system in the French nuclear reactor series. Based on its previous experience in evaluating I and C systems for P4/P'4 (1300 MWe) and N4 (1450 MWe) plants and to account for the first-ever aspect of such an upgrade, IRSN partitioned its assessment into four phases. This approach enabled taking into account the impact of RPN refurbishment at every level - system, hardware and qualification, software, operation, onsite requalification, health physics, fire protection and human factors. All six units in the CPO series have now been equipped with the new digital RPN. (authors)

    Electricite de France (EDF), the french national electricity company, is operating 54 standardized pressurizer water reactors. This about 500 reactor-years experience in nuclear stations operation and maintenance area has allowed EDF to develop its own strategy for monitoring of age-related degradations of NPP systems and components relevant for plant safety and reliability. After more than fifteen years of experience in regulatory transient data collection and seven years of successful fatigue monitoring prototypes experimentation, EDF decided to design a new system called SYSFAC (acronym for SYsteme de Surveillance en FAtigue de la Chaudiere) devoted to transient logging and thermal fatigue monitoring of the reactor coolant pressure boundary. The system is fully automatic and directly connected to the on-site data acquisition network without any complementary instrumentation. A functional transient detection module and a mechanical transient detection module are in charge of the general transient data collection. A fatigue monitoring module is aimed towards a precise surveillance of five specific zones particularly sensible to thermal fatigue. After the first step of preliminary studies, the industrial phase of the SYSFAC project is currently going on, with hardware and software tests and implementation. The first SYSFAC system will be delivered to the pilot power plant by the beginning of 1996. The extension to all EDF's nuclear 900 MW is planned after one more year of feedback experience.

    1990-01-01

    The French R7T7 nuclear glass composition was carefully selected to allow incorporation of some thirty different oxides found in fission product solutions. The resulting glass exhibits very low crystallization, and its physical and chemical properties are very similar to those of standard industrial glasses. Nuclear glasses have been shown to withstand α doses corresponding to several hundred thousand years under repository conditions. Predicting the long-term behavior of fission product glasses subjected to aqueous corrosion is no doubt the most difficult aspect of the problem. Predictions are necessarily based on mathematical models. A substantial research effort has been undertaken to identify all the basic corrosion mechanisms liable to control long-term alteration. These mechanisms are now relatively well understood, and provide the basis for developing the indispensable models. Realistic storage conditions exist under which glass alteration occurs at a very slow rate, and can fulfill its role as the first containment barrier for several tens of thousands of years

    Full text of publication follows. Aim Radioiodine 131 I (RAI) is currently used routinely in the treatment of hyperthyroidism including Graves disease (GD), toxic multi-nodular goitre (TMNG) and toxic solitary nodule (TSN). It has proved to be safe, efficient and relatively inexpensive therapy. But after more than 60 years, many protocols are coexisting and no consensus exists on the most appropriate way to prescribe RAI dose: fixed dose regime or calculated doses based on gland size or turnover of RAI. This is the first nationwide French survey assessing the current practices about radioiodine treatment in thyrotoxicosis. Methods: we sent a questionnaire to French nuclear medicine hospital units and cancer treatment centres (n=69) about their practices in 2012. Questions were asked about RAI treatment: objectives, way to prescribe the therapeutic dose and its factors, radioisotope use to explore thyroid function and method of gland size measurement. Results: we received 40 responses. Euthyroidism was a successful treatment outcome for 33% of French respondents whereas hypothyroidism was the aim for 26%. Antithyroid drugs were stopped 7 days on average (range 3-21 days) before therapy. 68% of physicians used ultrasound for thyroid volume measurement. Calculated doses were used by 40% of clinicians (Marinelli's formula: 80%). Factors influencing prescription were thyroid uptake (100%) based on radiotracer iodine-131 (33%) or iodine-123 (67%), thyroid volume (93%) and disease (80%). Fixed activities represented 60% of the prescribed doses (72,5% for TMNG and TSN). The administered dose was chosen between 1 to 3 levels of standard doses, according to the patient characteristics. Factors influencing this choice were disease, with respectively a median of 370 MBq (range:185-740), 555 MBq (185-740), 555 MBq (296-925) for GD, TSN and TMNG, thyroid volume (59%) and thyroid uptake (52%) with the radiotracer iodine-123 (30%) or technetium-99m (70%). Even physicians

    The safety goal for nuclear installations is to prevent the dispersal of radioactive substances, both in the work area and outside the buildings into the environment. It is therefore at the design stage, then during construction and subsequent operation that it is necessary to take preventive measures against the outbreak of fire, and to take precautions to ensure that the consequences will always be limited. The paper describes the arrangements made by the French safety authorities to provide protection against fire in both nuclear plants and nuclear fuel cycle installations at all these stages

    The energy flux diagram for France in 1970, underlines the disparity observed between the utilization factors in the final stage: 75% for the domestic and tertiary sector, 75% for industry and siderurgy, 65% for agriculture, and 25% for transports. The total utilization factor is 47.5% (124.4 MTEC used for 137.6 MTEC unused; the unit used being the Million of Tons Equivalent to Coal. Two dates are arbitrarily envisaged (1985 and 2000) in the evolution of the French energy technology and structure. The energy flux diagram predicted for 1985 should asked to atom nearly a quarter of the resources, with an enhanced part from hydraulics (+30%) and should involve geothermy, heat wastes and solar energy. An extrapolation predicts a spectacular-growth for 2000 due to the uranium share as a compensation to the decrease in that from oil, as for the transformation stage a neat increase in the electricity share is predicted together with 'tele-heat' and hydrogen production and, at the stage of utilization the mass penetration of 'tele-heat', especially of nuclear origin. The problem of the evolution of energy resources is also discussed [fr

    Over these last years, considerable information has been obtained on primary coolant chemistry, activity build-up and nuclear fuel behavior. As of December 1982, twenty three 900 MWe type reactors were in operation in France and about 1.3 millions of rods had been loaded in power reactors among which six regions of 17x17 fuel assemblies had completed successfully their third cycle of irradiation with a lead assembly burn-up of 37,000 MWd/MtU. Visual examination shows that crud deposited on fuel clads is mostly thin or inexistent. This result is due to the appropriate B/Li coolant concentration control which is currently applied in French reactors since several years. Correlatively, radiation field build-up is minimized and excessive external corrosion has never been observed. Nevertheless for higher coolant temperature plants, where occurrence of nucleate boiling could increase crud deposition, and for load follow and high burn-up operation, an extensive programme is performed jointly by Commissariat a l'Energie Atomique (CEA), Electricite de France, FRAMATOME and FRAGEMA to reduce even more the radiation field. This programme, described in the paper, includes: loop tests; on site chemical and radiochemical surveys; radiation field measurements; on site fuel examination crud-scrapping, crud analysis and oxide thickness measurements; hot cells examination. Some key results are presented and discussed in this paper. (author)

    Numerical simulations of compartment fires have been carried out in the French 900 MW and 1 300 MW nuclear power plants, to obtain quantitative data about this particular kind of risk: characteristic spreading times from one redundant electrical train to the other one, behaviour of important electrical components... The main stages of both studies were the following: selection of rooms, the location or function of which are essential for the plant safety in case of fire, on-site inspections to collect information about these rooms (amount of fuel, openings...), definition of fire scenarios, improvement of the fire model VESTA-PLUS, and, finally calculations using this computer code. The simulations have shown two major trends: i) the spreading times, without taking into account any external intervention, are always greater than half an hour, and ii) the specific design of the 1 300 MW power plants generally prevents one of the redundant train from being damaged due to a fire occurring in a room containing the other one. Examples of typical results obtained are given, showing the capability of application of the improved fire model to complex problems

    The detrimental genetic impact of nuclear facilities has been an important research issue in the past. We studied the birth sex ratio, technically sex odds, near nuclear facilities including all nuclear power plants in France, Germany, and Switzerland. We found evidence for an increase in the birth sex odds for distances of up to 40 km from nuclear facilities. Here, we update our analysis of the French data from 1968 to 2011 with most recent data from 2012 to 2014. Within 20 km from the considered 28 pertinent nuclear facilities in France we see a pronounced increasing sex ratio trend compared to the rest of France where the well-known highly significant global sex ratio decrease prevails. Correspondingly, within the 20 km minimum distance from nuclear facilities in France, the sex odds is elevated, relative to the rest of France, with a sex odds ratio (SOR) of 1.0063 (95%CI: 1.0031, 1.0095) p<0.0001. Therefore, the new French data corroborate our previous findings.

    Illustrated by many graphs and tables, this report comments and discusses the evolution of opinion surveys performed in France on the perception of nuclear risks through thirty annual IRSN opinion surveys. It appears that the opinion on nuclear is rather steady, and that French people have a rather rational perception of risk hierarchy. The first part outlines that unemployment is the main concern for French people, and that environmental concerns depend on current events. The second part analyses the perception of the nuclear risk with respect to other societal concerns and to other risks, and discusses the evolution of opinion from a quantitative to a qualitative sensitivity. The third part addresses the representations people have of nuclear activities and how they challenge the reality: perception of nuclear plants and of radioactive wastes, fear of a serious accident. The last part deals with issues related to responsibilities, abilities and governance: how actors of nuclear risk management are perceived, and expectations in terms of transparency and opinion plurality

    Very few studies have investigated the possible effects of environmental radiation and heat exposure on male reproductive function. We conducted a case control study to evaluate the various infertility risk factors in the military population of the french town of Brest to investigate an apparently high incidence of infertility in couples in which the man may have been exposed to occupational nuclear radiation. These findings suggest that in addition to well known medical factors, 'potential' exposure to heat or nuclear radiation could also be risk factors for infertility. (N.C.)

    Full text of publication follows: Current radiation protection standards of occupationally exposed workers are based on an extrapolation of cancer risks estimates derived from studies of the survivors of atomic bombings in Hiroshima and Nagasaki. In order to confirm these standards, International Agency for Research Cancer coordinated a retrospective cohort study to estimate the risk of cancer death after low-level exposure to gamma-ray, in a worldwide population of 400 000 nuclear industry workers in 15 countries. Methods: The present study is part of the international study and includes about 13,000 French nuclear industry workers of 10 contracting companies and subsidiary companies. This study was restricted to workers who wore a radiation dosimeter or badge. Contracting companies were selected on the basis of at least 100 workers in activity in 1996. A retrospective cohort was constituted. For each worker, we collected data concerning personal identifiers, occupational history, exposure history, vital status and cause of death. In order to guarantee the reliability of dosimetry data, we confronted monthly doses of X and gamma rays obtained from each company with monthly doses obtained from the National Institute of Radio Protection (I.R.S.N.). The cut off date was the 31 December of 2000. An incidence study is running within this cohort. Data relatives to poly-exposures, incident cancers and other pathologies, have being collected through a questionnaire form. Results: A total of 12,690 workers were included in the cohort, 1,457 could not be identified. Among the 11,233 identified workers, 280 deaths were recorded and 36% of them were cancer. Most of the workers were men (96%) and the median age at cut off date was equal to 41 years old. Only 25% of workers were exposed seven years or more. The median cumulative dose was equal to 3.1 mSv and 25% of workers had a cumulative dose superior to 22 mSv. Conclusion: Median cumulative dose was lower than expected as

  11. IRSN's viewpoint on the safety and radiation protection of French nuclear power plants in 2007

    International Nuclear Information System (INIS)

    2009-01-01

    This report presents the viewpoint of the IRSN on the safety and radiation protection of EDF's nuclear power plants (NPPs) in operation during 2007. It does not aim to be exhaustive but rather to highlight the points the IRSN considers important for safety. Contributing to maintaining a high level of safety and radiation protection in nuclear facilities in service is one of the seven challenges of the objectives contract signed between the French Government and the IRSN. Safety demands constant vigilance on the part of all the players involved. It is never definitively acquired and must remain a priority and continuously progress, with the plant operator remaining the first entity responsible for the safety of its facility. For the IRSN, part of this mission firstly involves carefully examining and taking into consideration national and international experience feedback, and new scientific knowledge resulting from research. The implementation of improvements, whether technical or organizational or relating to human skills, then comes secondly. This report comprises four sections. In the first section, the IRSN presents the main trends that emerged from its overall review of the safety of the in-service nuclear power plants. The second section addresses the events that have marked the year due to their impact on safety. It also presents a synthesis of the radiation protection events. The third section is devoted to anomalies displaying a generic nature for several power plants. The last section covers the significant changes implemented or scheduled. These are generally modifications or plans of action intended to improve safety performance in the operation or design of the facilities. In spite of sometimes significant disparities in the results between power plants, the IRSN draws the following conclusions from its global review of the year 2007. First of all, no event had serious consequences in the fields of either safety or radioprotection. This good result must

    International Nuclear Information System (INIS)

    2005-01-01

    The French institute of radiation protection and nuclear safety (IRSN) presents in this document its evaluation of the 'Clay 2005' file made by the ANDRA and which aims at demonstrating the feasibility of a disposal facility for high level and long living rad-wastes in the argillite formation of the Bure site. The critical points of the safety have been considered more thoroughly, together with the uncertainties concerning some important data and phenomena in relation with the confining properties of such a disposal facility. The basic geologic data gathered by the ANDRA about the Callovo-Oxfordian clay formation of the Bure site are sufficient to confirm the favorable intrinsic properties of this formation with respect to the confinement of wastes. The main possible disturbances of internal and external origin (thermal, hydrological, mechanical, chemical, climatic change, earthquakes, erosion..) would have no redhibitory impact on the overall confining capacity of the facility. The design safety principles retained for the exploitation of the facility and the post-closure safety aspects are globally satisfactory. Therefore, the IRSN considers the disposal of rad-wastes in the Callovo-Oxfordian argilite formation as feasible but in the case of a continuation of this project, several complementary informations would have to be supplied in particular concerning: the possible fracturing of the host and surrounding formations, the possibility of localized inhomogeneous fluid flows inside the surrounding formations, the improvement of our knowledge about the changes of the mechanical, physical and chemical properties of the site rocks and of concretes with time, the dimensioning of the metallic components of the facility (shafts, containers..), and the efficiency of the ventilation system with respect to the explosion risks inside B-type waste alveoles.

  13. Thermal stability of the French nuclear waste glass - long term behavior modeling

    2000-01-01

    The thermal stability of the French nuclear waste glass was investigated experimentally and by modeling to predict its long-term evolution at low temperature. The crystallization mechanisms were analyzed by studying devitrification in the supercooled liquid. Three main crystalline phases were characterized (CaMoO 4 , CeCO 2 , ZnCr 2 O 4 ). Their crystallisation was TO 4.24 wt%, due to the low concentration of the constituent elements. The nucleation and growth curves showed that platinoid elements catalysed nucleation but did not affect growth, which was governed by volume diffusion. The criteria of classic nucleation theory were applied to determine the thermodynamic and diffusional activation energies. Viscosity measurements illustrate the analogy between the activation energy of viscous flow and diffusion, indicating control of crystallization by viscous flow phenomena. The combined action of nucleation and growth was assessed by TTT plots, revealing a crystallization equilibrium line that enables the crystallized fractions to be predicted over the long term. The authors show that hetero-genetics catalyze the transformation without modifying the maximum crystallized fraction. A kinetic model was developed to describe devitrification in the glass based on the nucleation and growth curves alone. The authors show that the low-temperature growth exhibits scale behavior (between time and temperature) similar to thermo-rheological simplicity. The analogy between the resulting activation energy and that of the viscosity was used to model growth on the basis of viscosity. After validation with a simplified (BaO 2 SiO 2 ) glass, the model was applied to the containment glass. The result indicated that the glass remained completely vitreous after a cooling scenario with the one measured at the glass core. Under isothermal conditions, several million years would be required to reach the maximum theoretical crystallization fraction. (author)

  14. Numerical methods operational at the French Meteorologie Nationale for nuclear accident situation

    1990-01-01

    Since the Chernobyl accident, the Meteorologie Nationale has developed new numerical simulation methods to assist predictions provided as part of the meteorological support to the public authorities in the event of a nuclear accident. The present paper describes these new tools now operational at the Meteorologie Nationale. In the event of an accident, the first task of the forecaster is to anticipate the evolution of meteorological conditions at the site concerned. A fine scale, numerical forecasting model, PERIDOT, is used covering Western Europe with a resolution of 35 x 35 km. A comparison between PERIDOT wind forecasts and measurements at French NPS sites is presented which shows these forecasts to be of good overall quality, except for Chooz and Gravelines NPSs where the orographic complexity and the proximity of the sea require statistical corrections to be introduced. In all cases PERIDOT forecasts are clearly superior to those based on wind persistence. For accidents of any significance, the transport and dispersion of the atmopsheric polluants need to be evaluated as a matter of urgency. Again the forecaster has a vital role to play using numerical forecasting resources: in particular trajectory forecasts available by FAX within one hour of the meteorological Service Central d'Exploitation being alerted, and subsequently the Eulerian transport and diffusion code MEDIA which can be interfaced with either PERIDOT or EMERAUDE, a model operating on global meteorological conditions with a resolution of 150 x 150 km. This latter model has been tested against the Chernobyl accident with good results, the output is available in 4 to 5 hours after the alert and work is in hand to reduce the response time. Further studies are now in progress to provide a much finer regional resolution (5-10 km) and improved representation of wet and dry disposition at this resolution within MEDIA

  15. French experience concerning expansion compensating devices on the primary systems of nuclear reactors

    French experience in the use of large expansion bellows in the presence of hot sodium is extremely limited. This stems from the 'pool' structure of the primary circuit, adopted in France to eliminate the need to solve expansion problems affecting the primary piping of loop reactors. Furthermore, until the present time, the use of bellows on secondary circuits has neither been implemented nor considered. A few bellows nevertheless exist on the Phenix and Super-Phenix reactors, and these perform separation functions, for example, between sodium at different temperature and/or pressures, or tightness functions in gaseous environment at the component penetrations in the slabs. The dimension criteria applied to these bellows are the general rules for structural dimensioning. Since they do not form part of a circuit wall, they do not need to be discussed. Note, however, that these components have not raised any particular problems thus far. Expansion bellows exist in France on the primary circuits of certain nuclear reactors of the natural uranium/graphite/gas type. These reactors have been in operation for many years, and some lessons can be drawn from this experience in the use of bellows in representative conditions on power reactor circuits. Liquid sodium raises specific problems with respect to circuit operation and material behavior. However, many problems in the use of bellows are independent of the fluid conveyed in the circuits. This is why the experience gained with gas type power reactors appears to be useful in considering the possible future use of bellows on sodium reactor circuits

    In case of an accident in a nuclear power plant near the French-German border different schemes for dispersion calculations in both countries will currently be applied. An intercomparison of these schemes initiated from the German-French Commission for the safety of nuclear installations (DFK) revealed in some meteorological situations large differences in the resulting concentrations for radionuclides. An ad hoc working group was installed by the DFK with the mandate to analyse the reasons for the different model results and also to consider new theoretical concepts. The working group has agreed to apply a Gaussian puff model for emergency response calculations. The results of the model based on turbulence parameterization via similarity approach or spectral theory - have been compared with tracer experiments for different emission heights and atmospheric stability regimes. As a reference the old modelling approaches have been included in the study. The simulations with the similarity approach and the spectral theory show a slightly better agreement to the measured concentration data than the schemes used in the past. Instead of diffusion categories both new approaches allow a continuous characterization of the atmospheric dispersion conditions. Because the spectral approach incorporates the sampling time of the meteorological data as an adjustable parameter thereby offering the possibility to adjust the dispersion model to different emission scenarios this turbulence parameterization scheme will be foreseen as the basis for a joint French-German puff model

    Nuclear dissuasion is a slow and permanent process of adjustment to the strategic environment. French dissuasion adaptation to the new international environment covers a full decade, starting in the 1989-1992 era with a re-evaluation of defense programs. It has been followed by the 1994 defense white book which opens up the European perspective and reaches its peak in 1996 with a series of major decisions: renouncement of surface-to-surface missiles, launching of the M51 program, end of nuclear tests and shift towards simulation, dismantling of fissile materials production facilities etc. This process shows up two logics: the one of continuity with the confirmation of the bases of the French nuclear doctrine, and the one of discontinuity with significant changes in the general domain of the French nuclear policy. It also opens up questions about the field of application of dissuasion and the future of the nuclear consensus. (J.S.)

    Launched in 1986 by Electricite de France, the Probabilistic Safety Assessment of a French 1300 MWe Pressurized Water Reactor (called PSA 1300) was completed in 1989. The first objective was to assess the annual core damage frequency by identifying all the accident scenarii likely to contribute significantly to this frequency. The second objective of the study was to provide an automated computerized tool (software) for updating the assessment - in order to take new data and knowledge into account - and for performing numerous sensitivity studies easily. Its scope and characteristics render this study unique. Indeed, it required an effort amounting to 50 engineer-years. The results and the first lessons are presented in this paper. The PSA 1300 teachings will be extensively used for the design and operation of existing or future French nuclear power reactors

    Countries which export nuclear technologies, notably France, have developed mechanisms of financial support to incite private banks to finance the sale of reactors to foreign countries, notably EPRs in the case of France. After having briefly introduced this issue, and dealing with the French case, this publication indicates the concerned banks, and outlines that some of them finance nuclear projects which have been assessed by NGOs as dangerous in terms of nuclear safety. It notably presents the Angra 3 project in Brazil: its cost, its planning, its main safety problems (obsolete technology, building authorization awarded without any actual safety analysis, situation of conflict of interest for the Brazilian regulator). It also presents the Jaitapur project in India in which Areva is as well involved: costs, funding, planning, main risks (seismic risk area, safety level much lower than the one required in France, controversy on the impact study). The document finally explains why banks must not fund nuclear projects

    The behaviour of borosilicate glasses upon aqueous corrosion is controlled for long periods of time (>10,000 years) by processes which are not directly accessible by means of laboratory experiments. The analogical approach consists here to compare leaching performances between the french nuclear waste glass R7T7 and natural volcanic glasses, basaltic and rhyolitic ones. The three glasses were leached in the same conditions; open system, 90 deg C, initial pH of 9.7. Basaltic and R7T7 glasses having the same kinetic of dissolution, the basaltic glass was chosen as the best analogue. (author). refs., figs., tabs

    The association of veterans of nuclear tests(A.V.E.N.) has been created on the 9. june 2001. It concerns the military personnel, the Cea personnel and the contractors personnel that took part in nuclear tests in the Algerian Sahara and French Polynesia. A.V.E.N. has for objective information on the consequences of nuclear tests, the entitlement to have access to their medical file and the right to compensation for loss sustained by the victims. The inquiry bearing on 271 veterans brings to light that 93.4% of them have one or several diseases, 28.4% of them have or had one or several cancers. 77% of cancers happened before sixty years old and 36% before fifty years old. 45.4% died before sixty years old. The non cancerous digestive, osteo-muscular and cardiovascular pathologies are the most frequent. The children and grand children present inborn malformations (9.4% and 4.8%) and various diseases (24.3% and 5.5%). Despite that the critics that can be formulated, the results, compared to the British ones incite to go on. This preliminary inquiry must be completed by a greater number of answers. These results are an important argument to ask for an epidemiology inquiry on the whole of military and civil personnel that have participated to the nuclear tests in order to establish in a definite way the effects on health of nuclear tests and to draw consequences of it.

A la demarche globale representee par une irradiation pure et simple (grains humides, pommes de terre...) sont parfois associees des etudes souvent originales, d'ordre biochimique ou microbiologique (par exemple: alteration de l'amidon, metabolisme glucidique des tubercules irradies, radioresistance des levures

  6. Implemented organisation for subcontracting companies involved in the maintenance of the French nuclear stock - Sheet nr 39

    International Nuclear Information System (INIS)

    2011-01-01

    Every year, some 20,000 subcontracted salaried employees are mobilised for maintenance operations in the French nuclear reactors. Subcontracting is an answer to different needs: specific abilities, the short delay for maintenance during which a reactor is stopped, and which requires a very important contribution of labour, and specialised labour for some interventions. The document evokes a rigorous selection and certification process, and indicates the different specific training which are organised for anyone intervening in a nuclear power plant. It outlines that radiation protection and safety arrangements are the same for all (dosimetry), and that some measurements are performed on some temporary workers. Some data shows that these controls are efficient and that safety is improving

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

    1983-01-01

    The first part of the paper is devoted to the characteristics of the iodine adsorbers which equip French air cleaning systems and to their operating conditions. The analysis of the data obtained with in place testing of iodine filters is developed further on. Data already available and new complementary data to be obtained are examined. An analysis of the results of in place tests will give an idea of the rejection level observed for acceptance tests and will show the possible influence of several parameters (air velocity, relative humidity, ageing) upon the measured decontamination factors. Finally, an assessment is made of the evolution of French cleaning systems during the last few years and of the complementary measurements to be carried out in the frame of the standardized test method

    The Intergovernmental Agreement signed on November 12, 1992, between the governments of France and the Russian Federation instituted cooperation between the two countries for the safe elimination of the excess Russian nuclear weapons. France has allocated 400 million francs to this program, covering transportation and dismantling of nuclear weapons, interim storage and subsequent commercial use of the nuclear materials from the dismantled weapons, nuclear materials accountancy and safeguards, and scientific research. The concept of loading commercial Russian reactors with fuel fabricated from the plutonium recovered from dismantled nuclear weapons of the former Soviet Union is gaining widespread acceptance, and is at the heart of the French-Russian AIDA/MOX project

    Sube, R [comp.

    1985-01-01

    This dictionary covers nuclear engineering defined in its general sense as applied nuclear physics: industrial and other applications of nuclear power, isotopes and ionizing radiation, nuclear materials, nuclear facilities and nuclear weapons together with their scientific and technological fundamentals. During the compilation of terms, great attention was only given to generally valid basic expressions and to special terms where these occurred in all four languages. A great number of textbooks and monographs, as well as specialist journals covering many years, have been evaluated. Detailed attention has been paid to standards. Of importance in nuclear engineering are the international standards of the International Atomic Energy Organization (including the terminology employed by the International Nuclear Information System INIS), the International Organization of Standardization, the Council for Mutual Economic Assistance, the World Energy Conference, the International Electrical Engineering Commission, and also a great many national standards which, unfortunately, frequently deviate from one another as regards definition and, in particular, designation.

    The consequences of an industrial pollution for the population and the environment depend not only on the nature and extent of the pollution, but also of the characteristics of concerned environment: the use that man made of it, and of the man's habits, notably food practices. To improve the consideration of the specificities of territories in its evaluations and its recommendations, in normal operation or in accident and post-accident situations, the Institute for Radioprotection and Nuclear Safety characterizes the environment of the nuclear installations. This standardised measurement of the environmental and population characteristics will be useful in risk assessment and management, and in all the operational stages of a nuclear installation. This characterization concerns the inventory of the main agricultural productions (vegetable and animal), the important agricultural dates (seeding, harvest) and the practices and eating habits of animals, the industry and the local food-processing, as well as on the food practices of the persons which live around the French nuclear power plant. National surveys have identified the major characteristics of French eating habits. Above and beyond the fact that these surveys do not consider local specificities, the use of their results for dosimetric assessments has certain drawbacks: the categories of foodstuffs most vulnerable to contamination in post-accident situations (fresh fruit and vegetables, fresh milk and cheeses) are very rarely described in detail; representation of the eating habits of an 'average' population does not give us as the behaviors of the most sensitive groups. The prime objective of local studies is to describe eating habits (rations and local production rates) of potentially most exposed population around nuclear facilities which may cultivate various foodstuffs. These comparative studies highlighted the important variability of the particular eating habits of the French population

  1. Review of geomechanics data from French nuclear explosions in the Hoggar granite, with some comparisons to tests in US granite

    Heuze, F.E.

    1983-05-01

    Numerous unclassified reports on the French nuclear explosions in the Hoggar (1961-1966) were reviewed from the standpoint of geomechanics. The following aspects of the tests are summarized: spectral content of the tests compared to U.S. results; shock front positions with time; cavity radius as a function of yield, coupling, density of rock, rock shear strength, and overburden; radial pressure, tangential pressure and peak velocity as a function of distance and yield; pressure vs. time at various distances; mechanical properties of granite; scaling laws for acceleration, velocity and displacement as a function of yield and distance for all Hoggar shots; extent of tunnel damage as a function of distance and yield; time to collapse of chimney as a function of yield, or cavity radius; extent of granite crushing and disking as a function of distance and yield cavity height relation to cavity radius; faulting and jointing on the Taourirt Tan Afella massif; and influence of water content on cavity radius vs. yield. Whenever possible, these French data are compared to corresponding data obtained in the U.S. granite events Hard Hat, Shoal, and Piledriver. The following results emerge from the comparison: (1) agreement is found between the French and U.S. experience for: mechanical properties of the granites, rock damage due to the blast, and yield-scaled peak values of acceleration, velocity and displacement; and (2) lack of agreement exists for: cavity size, chminey height, and time to cavity collapse. Average spacing of rock joints also was about 5 times greater in the Hoggar

    2015-01-01

    The possibility that nuclear or other radioactive material could be used for malicious purposes cannot be ruled out in the current global situation. States have responded to this risk by engaging in a collective commitment to strengthen the protection and control of such material and to effectively respond to nuclear security events. States have agreed to strengthen existing and established new international legal instruments to enhance nuclear security around the world. Nuclear security is fundamental in the management of nuclear technologies and in applications where nuclear or other radioactive material is used or transported. Through its nuclear security programme, the IAEA supports States to establish, maintain and sustain an effective nuclear security regime. The IAEA has adopted a comprehensive approach to nuclear security. This recognizes that an effective national nuclear security regime builds on: the implementation of relevant international legal instruments; information protection; physical protection; material accounting and control; detection of and response to trafficking in such material; national response plans; and contingency measures. With its nuclear security series, the IAEA aims to assist States to implement and sustain such a regime in a coherent and integrated manner. The IAEA Nuclear Security Series comprises: Nuclear Security Fundamentals, which include objectives and essential elements of a State?s nuclear security regime; Recommendations; Implementing Guides; and Technical Guidance publications. Each State carries the full responsibility for nuclear security, i.e. to provide for the security of nuclear and other radioactive material and associated facilities and activities; to ensure the security of such material in use, storage or in transport; and to combat illicit trafficking and the inadvertent movement of such material. It should also be prepared to respond to a nuclear security event. The IAEA recommendations for the protection of

    2012-01-01

    With 58 reactors in operation, France is at 75% a nuclear-dependent country for power generation. For forty years no calling into question of this policy has been possible. The Fukushima catastrophe of March 11, 2011 has changed the deal. Several countries, like Germany, Switzerland, Belgium and Italy have taken the decision to get out of nuclear energy. In France, the taboo question of its abandonment has moved to the front of the scene. Some political parties have proposed a significant reduction of the nuclear share in the energy mix while some 'zero nuclear' scenarios are already on the table. (J.S.)

    The implementation of the new ICRP recommendations and the diversity of industrial exposure materials make it necessary to modify our approach of assessing internal dosimetry. This paper describes a methodology developed to asses different parameters such as activity concentration and particle size distribution at the workplace; physico-chemical characteristics of industrial dust handled; and in vitro and in vivo solubility in order to determine the absorption rate blood. The determination of such specific parameters will lead to dose calculation in terms of committed effective Dose Per Unit of Intake (DPUI). Results obtained for an industrial uranium dioxide, UO 2 , at a French nuclear facility are presented. (author). 21 refs., 2 figs., 4 tabs

    Jacques Chirac speech on ''Ile Longue'' provoked a vigorous reaction in Germany, and has been perceived as a dangerous provocation in the context of the ongoing and difficult negotiations with Iran. However, Germany should accept its responsibilities in the field of nuclear armament, for the sake of the interdependence of the countries of Europe. Deterrence still has a fundamental role in international relations, and gives one country the power to influence another by preventing the use of force. In view of the setback of the French President intervention and German unease in security and defence matters, the European dimension must be given a special role in establishing and reinforcing a common strategy, indispensable in today world.

    Across the EDF nuclear fleet, the chemical risk linked with hydrazine hydrate storage, unloading and injection has received much attention in the past decades. Since 1997, continuous investigation into the substitution of dangerous and carcinogenic chemicals has been conducted and regularly updated by EDF. As a downstream user of hydrazine hydrate, EDF is concerned by REACH legislation, in force since 1 June 2007. As part of the compliance process with REACH, EDF provided its hydrazine hydrate suppliers with information regarding the uses of the chemical. This was done by the end of 2008, as per REACH deadline. On the other hand, EDF contributed throughout European Chemicals Agency consultation phase by submitting data relating to hydrazine hydrate uses across nuclear sites. The absence of a suitable hydrazine hydrate replacement product, able to satisfy the entirety of technical requirements, entails rigorous arrangements to be implemented in order to segregate the zones where use of hydrazine is made and therefore eradicate the risk to personnel regarding hydrazine effects. Consequently, a number of engineering changes and modifications are to be carried out on the chemical injection systems of 58 French nuclear power plants over the next few years as part of the EDF Hydrazine Fleet Programme.

    TANDEM (Tsunamis in the Atlantic and the English ChaNnel: Definition of the Effects through numerical Modeling) is a French research project dedicated to the appraisal of coastal effects due to tsunami waves on the French coastlines, with a special focus on the Atlantic and Channel coastlines, where French civil nuclear facilities have been operating since about 30 years. This project aims at drawing conclusions from the 2011 catastrophic tsunami, and will allow, together with a Japanese research partner, to design, adapt and validate numerical methods of tsunami hazard assessment, using the outstanding database of the 2011 tsunami. Then the validated methods will be applied to estimate, as accurately as possible, the tsunami hazard for the French Atlantic and Channel coastlines, in order to provide guidance for risk assessment on the nuclear facilities. The project TANDEM follows the recommendations of International Atomic Energy Agency (IAEA) to analyse the tsunami exposure of the nuclear facilities, as well as the recommendations of the French Nuclear Safety Authority (Autorité de Sûreté Nucléaire, ASN) in the aftermath of the 2011 catastrophe, which required the licensee of nuclear facilities to conduct complementary safety assessments (CSA), also including "the robustness beyond their design basis". The tsunami hazard deserves an appraisal in the light of the 2011 catastrophe, to check whether any unforeseen tsunami impact can be expected for these facilities. TANDEM aims at defining the tsunami effects expected for the French Atlantic and Channel coastlines, basically from numerical modeling methods, through adaptation and improvement of numerical methods, in order to study tsunami impacts down to the interaction with coastal structures (thus sometimes using 3D approaches) (WP1). Then the methods will be tested to better characterize and quantify the associated uncertainties (in the source, the propagation, and the coastal impact) (WP2). The project will

    The French authority of nuclear safety (ASN) publishes on its web site (http://www.asn.gouv.fr) the formal notices and official statements addressed by the ASN to the concerned responsible persons (operators of nuclear facilities, directors of companies etc..) when anomalies requiring a corrective action have been noticed during on-site or off-site safety inspections. This document brings together the formal notices addressed by the ASN since June 2000 and up to April 2002. (J.S.)

  17. Chernobyl: exclusive investigation. How the French nuclear lobby buries the truth in contaminated areas. The After-Chernobyl or 'Living happy' in contaminated area

    International Nuclear Information System (INIS)

    2006-01-01

    According to the results of this inquiry, the CEPN (study centre on assessment of protection in the nuclear sector) has been created by the main actors of the nuclear industrial sector (EFG, Cogema, CEA and IRSN) and is at the origin of the ETHOS and CORE projects. Moreover, these projects have been financed by public funds. It also shows that the FNSEA (farmer trade union) has been allied to the French nuclear lobby for the distribution probably contaminated and radioactive foodstuff. It evokes the case of Belarus researcher who denounced such contamination and the misappropriation of international funds, and who was sent to jail. It comments the collaboration between the French nuclear sector and the Belarus regime, denounces how the truth about Chernobyl has been hidden, the cynical results of the ETOS program which would imply the consumption of contaminated foodstuff in France in case of nuclear accident. Some proposals are made: to dismantle the CEPN, to stop the participation of French organisations to the CORE and FARMING programs, creation of an independent commission on the consequences of the Chernobyl accident, and so on. For the authors, phasing out nuclear is the only solution o avoid a new Chernobyl

  19. Nuclear research centres in the 21st century: The French perspective

    International Nuclear Information System (INIS)

    Graviere, M. de la

    2001-01-01

    In France the reactor technology is mature and R and D needs for reactors are small. However, there are substantial R and D needs in the electro-nuclear field. These include optimization of operation of nuclear power plants and the associated factories and to have a long term vision for the nuclear technologies. The State continues to be a major provider of resources for the long term strategic objectives. However, lack of resources has resulted in shutting down of some large facilities and it is becoming difficult to refurbish some large experimental tools. The possibility of earning resources through solving complex problems beyond the nuclear field is, therefore, under exploration. Nuclear research centres are also looking into new advanced technologies (energy, micro electronics, materials, bio-technology) and for development of partnership with other public research organisations. The issue of preservation of expertise is being addressed by development of networks between the European centres working in the same field. Cost and risk sharing of nuclear R and D is being pursued by collaboration with countries outside Europe, namely the USA, Japan and China. Public perception of nuclear energy is being enhanced by opening CEA centres to the public. (author)

    As an epidemiological study performed by the INSERM highlighted an excess of childhood leukaemia within 5 km around nuclear power plants during the 2002-2007 period, this meeting has been organised to discuss this issue. After a presentation of these results, a contribution discusses the context and research perspectives on the relationship between childhood leukaemia and nuclear sites. After the reported debate, a contribution presents the conclusion of a work-group on childhood leukaemia and ASN works, and a last one presents the activities of a work-group gathering the ANCCLI, IRSN and InVS on the health impact of nuclear installations. A debate on these issues is reported

  1. Generic results and conclusions of re-evaluating the flooding protection in French Nuclear Power Plants

    2002-01-01

    The partial flooding of the Blayais site, occurred on December 1999 has led to a large scale re-examination of the measures to prevent and limit the consequences associated with all contingencies or combinations of them, which could lead to external flooding of any of the 19 French sites, equipped with pressurized water reactors. An Action Program has been launched by Electricite de France and a methodology has been approved, consisting of: defining of principles for re-evaluating external flooding risks together with the relevant arrangements; applying the principles to each site and showing that the margins adopted are sufficient for achieving an acceptable safety level. The implementation of the program throughout all sites with PWR in France will extend to 2005

    Almost immediately after the TMI accident, Electricite de France (EdF), Framatome and the French safety authorities started a large scale program of actions designed to analyse and understand the causes of the accident, and draw lessons applicable in France. This paper discusses these actions and the main conclusions of TMI accident analysis in France, notably: the fundamental role of plant operators, and the importance of operator training, written instructions and procedures, and diagnostic aids; the importance of feeding back operating experience to design teams, and incorporating the results of accident and post-accident studies in operating procedures; the necessity to improve knowledge of core cooling modes, including during two-phase flow and natural circulation; measures to improve particular systems and components [fr

  3. Microbial induced corrosion in French concept of nuclear waste underground disposal

    International Nuclear Information System (INIS)

    Feron, D.; Crusset, D.

    2014-01-01

    The objective of this paper is to give a short overview of how the bacteria, that may influence the corrosion behaviour of metals and alloys, are taken into account in the French concept of geological repository. It is important to underline that microbial induced corrosion is not a new corrosion phenomena but the presence of bacteria may modify (increase or decrease) anodic or cathodic corrosion reactions. In aerobic conditions, high corrosion rates may be obtained due to the bio-oxidation of pyrites. Under anaerobic conditions (longer period), bacteria may have negative (localised corrosion) or positive (consumption of hydrogen) effects. The mixed conditions (with and without oxygen) may be the most dangerous period for localised corrosion of metals and alloys due to the coupling and galvanic corrosion phenomena enhanced by aerobic and anaerobic bacteria. The first conclusions lead to consider that MIC is a 'short term' issue rather than a long term one. (authors)

  4. Safety of Nuclear Power Plants: Design. Specific Safety Requirements (French Edition)

    International Nuclear Information System (INIS)

    2017-01-01

    This publication establishes requirements applicable to the design of nuclear power plants and elaborates on the safety objective, safety principles and concepts that provide the basis for deriving the safety requirements that must be met for the design of a nuclear power plant. It will be useful for organizations involved in design, manufacture, construction, modification, maintenance, operation and decommissioning of nuclear power plants, as well as for regulatory bodies. A review of Safety Requirements publications was commenced in 2011 following the accident in the Fukushima Daiichi nuclear power plant in Japan. The review revealed no significant areas of weakness and resulted in just a small set of amendments to strengthen the requirements and facilitate their implementation, which are contained in the present publication.

    Economic wealth is the result of the three factors: natural resources, human work and technological know-how; the last being essential to make full use of the first two. The transfer of technology is not only a matter of training engineers or technicians but of creating a real network of knowledge and abilities so that the technologies can be fully assimilated and used according to the specific goals of the country, so a basic nuclear education is absolutely necessary, so the operation of a raining and research centre is essential. For this reason the CEA and its subsidary Technicatome have undertaken the study and construction of the Esfahan Nuclear Technology Centre (ENTEC). The main objectives of this centre are: the nuclear reactors, the study of nuclear fuels and industrial applications

  6. From the 'Le Blayais NPP' flooding in 1999 to the review of French regulation for the protection of nuclear facilities against external flooding

    International Nuclear Information System (INIS)

    Dupuy, P.

    2011-01-01

    On 27 December 1999, a severe storm occurred in the vicinity of the 'Le Blayais' Nuclear Power Plant located on the banks of the Gironde estuary. The severe storm-driven waves coincident with high water levels in the Gironde estuary exceeded the worst-case scenario considered at the design of the site protection against flooding, resulting in the scram of three out of four units and severe nuclear island flooding. Several underground rooms sheltering equipment important to safety were flooded. This partial flooding incident has called into question the design bases defined in the French Basic Safety Rule (BSR) I.2.e for the protection of French NPPs against external flooding in particular in terms of flood events and combinations of flood events considered for the design. It has also revealed some weaknesses in the existing measures implemented, especially the site protection dykes, the protection of equipment important to safety, the warning systems and the emergency organization. Following this incident, in addition to the rush through protection measures undertaken on Le Blayais NPP, the utility Electricity De France (EDF) has launched a wide review of the protection of all French NPPs against external flooding. This review is based on a new and more comprehensive methodology for the protection of NPPs against external flooding (called 'REX Blayais methodology'), including a reassessment of flood events and their combinations and of all protection measures. This review has led EDF to carry out a large number of modifications and improvements at all NPP sites. 'REX Blayais methodology' and its application to all French NPPs were submitted to the approval of the French Nuclear Safety Authority (ASN) in 2001 and then in 2007 after being analyzed by its technical support IRSN (French Institute for Radioprotection and Nuclear Safety). The methodology and the level of protection of the NPPs thanks to all the improvements and modifications performed by the utility were

    2014-01-01

    A recent opinion survey has been organized to assess how the issue of the lifetime extension of nuclear power plants was understood by the man on the street in France. 20 people have been interviewed after participating to a meeting in which 3 experts from different opinions on nuclear energy have shared their vision of lifetime extension. It appears that lifetime extension is not considered as an issue in itself but belongs to a more important issue that is the future of nuclear energy. Most people do not disagree with the idea of lifetime extension if this extension does not go beyond 10 years and their agreement is strongly correlated with other issues like the management of radioactive waste, the quality and follow-up of sub-contractors and the real alternatives to nuclear energy. 5 profile types have been identified from the most reluctant to the use of nuclear energy who consider lifetime extension as a leap forward in the bad direction to the most confident who agree with both nuclear energy and lifetime extension strategy.

    Forty years after the first bomb in Moruroa, a conference to promote recognition and justice for all victims of nuclear tests. More than thirty speakers, scientists, legal experts, parliamentarians and members of associations from French Polynesia, Australia, Fiji, New Zealand, the United States, Japan, the Netherlands and France debated on June 29-30, at the President's palace in Papeete, on the rights of the victims of nuclear tests to be recognized by nuclear powers. During this conference, we heard scientists explain very clearly that contamination and irradiation had widespread consequences including on the gene pool of the victims. Today, damage found on the chromosomes of Polynesian thyroid cancer patients who lived 1000 km away from Moruroa is ten times higher than damage found on average nuclear workers. Researchers tell us that many of those who worked on nuclear sites die earlier. Average life expectancy for the veterans from New Zealand is for example 51 years - and for most of them a life marred by suffering and cancers. Researchers tell us that conducting credible surveys is becoming more and more difficult as the impact of radiations that were absorbed 20, 30 or even 40 years earlier is getting more difficult to discern from damages due to old age or other illnesses. Testimonies and information given at this conference are indispensable for the public to realize the actual impact of the nuclear tests as well as show the elected representatives how urgent it is to meet the expectations of the victims. The suffering and strong discontent of the former test site workers moved the parliamentarians as well as the public. The strong words that were said will have to give a human face to the law we will have to implement in order to do justice to the victims. An impact of nuclear testing on health and environment are experienced by many peoples in the world. The testing nations are of course the ones who should compensate the victims. But there is also

    International Nuclear Information System (INIS)

    Conte, M.

    1986-05-01

    Increasing knowledge and lessons learned from starting and operating experience of French nuclear power plants, completed by the experience learned from the operation of foreign reactors, has contributed to the improvement of French PWR design and safety philosophy. Based on a deterministic approach, the French safety analysis was progressively completed by a probabilistic approach, each of them having possibilities and limits. As a consequence of the global risk objective set in 1977 for nuclear reactors, safety analysis was extended to the evaluation of events more complex than the conventional ones, and later to the evaluation of the feasibility of the offsite emergency plans in case of severe accidents

  12. Project for a realistic energy transition - The contribution of the French Nuclear Energy Society (SFEN) to the national debate on energy transition

    International Nuclear Information System (INIS)

    2013-01-01

    In this publication, the SFEN association first outlines the criticality of the energy issue for the world: energy production must be increased while the use of fossil energies must be decreased to reduce CO 2 emissions. This will need a new energy model to be implemented. The authors briefly characterize the French situation regarding energy and its objectives. They outline the major requirement: the reduction of the use of fossil energies. They suggest a slowing down of energy demand through a policy of energy efficiency. This decrease of the use of fossil energies should result in an increased share of electricity in the energy mix. The authors comment the benefits, limitations and uncertainties related to renewable energies. They also address the role of nuclear energy in the French situation with respect to purchasing power, competitiveness, de-industrialisation, unemployment and trade balance. They criticize the objectives of reduction of the nuclear share in the energy mix, and finally briefly evoke world perspectives and French orientations. In parallel, other information are provided about the relationship between nuclear and CO 2 , the situation in Germany, renewable energies, nuclear safety, the issue of nuclear wastes, and the EPR

    1977-01-01

    For several years the Commissariat a l'Energie Atomique (CEA) has been organizing nuclear safety exercises in most nuclear industrial facilities, especially in fuel element fabrication plants, many of which are classified as basic nuclear facilities. The subject and extent of each exercise are decided by mutual agreement between the management of the facility and the CEA officials in charge of Assistance in Protection and Nuclear Safety (APSN). The authors deal with such subjects as criticality accidents (evacuation of facilities, regrouping of personnel, rescue operations etc.) and fire involving large quantities of radioactive material (protection of the environment by spraying water on fumes laden with radioactive aerosols etc.). During these exercises use is made of the resources available with the safety services of the facility, one or more mobile nuclear action teams of the CEA and the appropriate resources within the competence of public authorities, e.g. Civil Defence, the fire brigades, the Gendarmerie etc. Each exercise is followed by a meeting which gives an opportunity for constructive criticism and for the adoption of measures best suited for solving problems which invariably arise, such as choice of methods and resources, co-ordination of their simultaneous or gradual application and so on.

  14. An evaluation of the production of solid radio-active waste in the Tricastin nuclear power station and, more generally, in the other French nuclear power stations

    International Nuclear Information System (INIS)

    Cuisenier, R.G.

    1986-01-01

    The importance of the effect of processing and packaging of solid radio-active wastes on the necessary staff, on the dosimetry acquired by this personnel and on the running costs will be presented, thus permitting a quantitative evaluation of the different types of waste produced, not only for the Tricastin plant but also for any typical French nuclear plant. Experience in the Tricastin power plant has shown that the volume of solid wastes can vary considerably depending on the different problems which can arise during production (cooling system leaks or less regular incidents). The different techniques used will be relooked at in order to facilitate the explanation of these fluctuations in the volume of waste produced and the measures which can be taken to limit them. The different measures which have been taken to improve performance in this domain will be presented: improvements in equipment, in methods, and in the increased awareness of the personnel concerning these problems

  15. Safety of Nuclear Power Plants: Commissioning and Operation. Specific Safety Requirements (French Edition)

It refers to decisions taken at the national level after the Fukushima accident, recommendations after European stress tests, and recommendations after the extraordinary meeting of contracting parties at the Convention on Nuclear Safety of August 2012. For different topics, this document recalls the recommendations made by the peer review, indicates the ASN's opinion and progress or ASN's requirements for different power stations. The first part addresses the recommendations made by peers and based on the European review. Topics concern natural hazards (effects, detection, inspections and controls related to earthquakes, margin assessment with respect to flooding and natural hazards), the loss of safety systems (cooling systems, electricity supplies, actions, instruments, training, and so on), the management of a severe accident (reference levels, measures, guides, exercises, training, management of contaminated water, radiation protection, premises). The second part deals with topics addressed within the frame of the Convention: national organisations, organisations in an emergency and post-accidental situation, international cooperation. A third part addresses the follow-up of additional measures issued by the ASN

    2011-07-01

    The materials constituting the condenser tubes of French nuclear power plants display a great diversity and are subject to different degradations, known from the operational feedback from experience. Copper alloys (mainly brass), which were bound to disappear in renovated condensers, are still significantly present, due to their unique bacteriostatic ability. Brass tubes lifetime is still governed in general by steady abrasion, as evaluated by eddy current nondestructive testing. However, an atypical NDE (non-destructive evaluation) behavior has led to spot a new damage: localized under-deposit pitting corrosion on the raw water side, caused by the particular quality of water chemistry and heavy scaling of the tube surface. This damage is likely to overcome steady abrasion for tube life prediction. Prevention includes a tighter look at NDE indications and improved descaling solutions (chemical or mechanical). Other specific damages have been reported from operation feedback: the main one was accidental stress corrosion cracking, which has occurred on some recently renovated brass condenser tube bundles. Thanks to a metallurgical and mechanical study, its cause was found in the manufacturing process. This experience has resulted in tightened specifications for brass tubes manufacturing. Stainless steel and titanium still appear more damage-resistant and represent a safe solution when no microorganism issue is present. The degradation feedback, confirmed by NDE inspections, is very low in French power plants. However, titanium hydriding still represents an issue when cathodic protection is present. Furthermore, some other damages have been reported on titanium, like isolated steam erosion. Vibration fatigue damage has been observed on stainless steel tubes, but it is more in relationship with the condenser design than with the material itself. (authors)

    2013-01-01

    The aim of this publication is to provide practical guidance for public information officers on the preparation for and response to a nuclear or radiological emergency, and to fulfil in part functions assigned to the IAEA in the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), as well as meeting requirements stated in IAEA Safety Standards Series No. SF-1, Fundamental Safety Principles, and in IAEA Safety Standards No. GS-R-2, Preparedness and Response for a Nuclear or Radiological Emergency. Under Article 5(a)(ii) of the Assistance Convention, one function of the IAEA is to collect and disseminate to States Parties and Member States information concerning methodologies, techniques and results of research relating to response to nuclear or radiological emergencies. IAEA Safety Standards Series No. GS-R-2 establishes the requirements for an adequate level of preparedness for and response to a nuclear or radiological emergency in any State, and specifies that 'All practicable steps shall be taken to provide the public with useful, timely, truthful, consistent and appropriate information throughout a nuclear or radiological emergency' in the response phase. It also requires 'responding to incorrect information and rumours; and responding to requests for information from the public and from the news and information media'. This publication provides guidance in the form of action guides and information sheets that can be easily applied by a State to build a basic capability to respond to a nuclear or radiological emergency. This guidance should be adapted to fit the user State's organizational arrangements, language, terminology, concept of operation and capabilities. This publication is published as part of the IAEA's Emergency Preparedness and Response series and complements the Manual for First Responders to a Radiological Emergency in the parts related to the tasks of public information officers.

    Despite of the unlikeliness of a nuclear accident, emergency planning is a must. It has several aspects: Internal Emergency PLan, Specific Intervention Plan, Post Accident and Relief specialized Plan. As a whole, the organisation is similar to the one used for others industrial risks. In a 'Department', the supervisor for overall emergency action is the 'Prefet', a high civil servant appointed by the Cabinet and responsible for nuclear security; all the other civil servants are under the Prefet's command and assist him. A national post-accident plan is being worked out; it will cover all the fields of intervention: control, administration of stable iodine, sheltering or evacuation. (author)

    The activities of artificial radionuclides in the environment have being strongly decreasing since 50 years. Nowadays the activities of 3 H and 14 C widely predominate, but they cannot be still considered as artificial radionuclides, except nearby the nuclear installations where they constitute the most abundant radioactive releases. In terrestrial environment this influence is limited to the surroundings of 5 sites, although most of nuclear sites and nuclear medical centers are involved in the contamination of the aquatic environment downstream the releases and in the Channel. Since 1987 the doses to the French population have been mainly induced by 14 C and 137 Cs. (author)

    This report of the French National Assembly first describes the objectives of the development of the civilian nuclear energy in India as a response to energy challenges faced by this country, and the India's need of an international cooperation to enable the development of such an electronuclear program. Then, it comments the relationship between India's access to civilian nuclear cooperation and the evolution of India's position with respect to the non-proliferation international regime, describing the current framework of nuclear cooperation with India, recalling Indian commitments and the decisions taken by international institutions, the decisions of the Nuclear Suppliers Group (NSG), and the current non-proliferation international regime. The report then describes the contents of the French-Indian agreement, and the general characteristics of the French civilian nuclear cooperation policy. A synthesis of the discussion of the Commission is given, followed by the bill text, and the texts of several official French and Indian statements

    Exposure to neutron radiation in the nuclear industry is normally limited to a small number of workers essentially EDF employees operating in specific areas. Operational collective dose due to neutron exposure is almost negligible compared to the rest of the external doses (less than 2 % in the collective dose equivalent). But this risk represents a significant fraction of the annual dose equivalent of those exposed. Suggest specifications for individual dosemeters which would ideally meet both technical and practical requirements. (author)

  12. A Brief Comparative Study on R and D Collaboration Strategy in US and French nuclear utilities

    2014-10-15

    So far KHNP's R and D strategy has been evaluated as 2.5th generation R and D management and R and D investments are focused to the key technologies such as Korea's own nuclear reactor design(like APR1400) development, engineering gap lists elimination(plants trouble shooting), construction/operation process enhancement, etc. But when we compare our R and D strategy with US and France utilities, we can find a lot of differences and the need of improvement to accelerate overseas export of nuclear power plants(technologies) and to be a world top class nuclear operator. One of prominent difference is R and D collaboration strategy. The definition of R and D collaboration has evolved over the years, but for this paper I use it to mean the process where multiple parts of an organization or stake holder work together toward a set of common goals. And by co-funding or cost sharing, collaborative R and D can reduces financial and technical risk and encourages knowledge exchange, supply chain development and in return, collaborative R and D can produce more advanced, complex, effective, efficient R and D products in relatively short time with relatively less budget. UK's technology strategy board estimated that Each we invest in collaborative R and D typically returns around in GVA(Gross Value Added)

    2013-01-01

    The 'Autorite de surete nucleaire' (ASN) requested licensees to undertake stress tests, called complementary safety assessments (CSA), of their installations on May 5th 2011, following the accident that occurred in Japan on March 11th 2011. Their mission consisted in providing feedback on the consequences of potential extreme events. In this process, all the French facilities were divided into three categories of decreasing priority, depending on two main factors: on the one hand, their vulnerability to the various phenomena that led to the Fukushima accident, and on the other hand, the amount of radioactive elements that would be dispersed in the event of a failure of the safety functions. On the 79 high-priority facilities, only five of them are research or experimental reactors (including two currently shutdown or in decommissioning) and their operators (the 'Comissariat a l'energie atomique et aux energies alternatives' (CEA) and the 'Institut Laue Langevin') submitted their reports to the ASN on September 15 th 2011. Concerning the lower-priority facilities, including three other facilities (two research reactors operated by the CEA and a facility operated by ITER Organization) the deadline was September 15 th 2012. Finally, the remaining facilities were not asked to submit a report yet, but they will have to do it later, mainly on the occasion of their next periodic safety review. The analyses of the cliff-edge effects, that may occur in extreme situations (exceptional scale event, combination of several disasters...), led to the definition of a hardened safety core concept by the 'Institut de radioprotection et de surete nucleaire' (IRSN). This hardened safety core of structures, equipment and organizational measures must ensure the ultimate protection of the concerned facilities in extreme situations : it is designed to prevent severe accidents (or curb their progression), limit large scale releases for extreme accidents, and enables the operating teams to

  14. Clinical Training of Medical Physicists Specializing in Nuclear Medicine (French Edition)

    International Nuclear Information System (INIS)

    2012-01-01

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasingly technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for nuclear medicine. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists who are based in a clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement for Research, Development and Training related to Nuclear Science and Technology (RCA) for the Asia-Pacific region. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in this region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in nuclear medicine was started in 2009 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experience of clinical training in Australia, Croatia and Sweden and was moderated by physicists working in the Asian region. The present publication follows the approach of earlier IAEA publications in the Training Course Series, specifically Nos 37 and 47, Clinical Training of Medical Physicists Specializing in Radiation Oncology and Clinical Training of Medical Physicists

    Taking into account the large numbers of valves (about 10000) of a PWR nuclear power plant, the importance of some valves in the safety functions and the cost resulting from their unavailability, the individual operability of these equipments has to be ensured at a high reliability level. This assurance can be obtained by means of an effort at all the stages which contribute to the quality of the product: design, qualification tests, fabrication, tests at the start-up stage, maintenance and tests during the power plant operation, experience feedback. This paper emphasizes more particularly on the tests carried out on loops of qualification [fr

    2011-05-01

    Members of the French Parliament, representatives of the French nuclear safety authority (ASN), of the Academy of Sciences, researchers, and associations argue on major natural risks and their evaluation, notably by referring to the earthquake and tsunami which caused the Fukushima accident. They discuss the predictability of these phenomena, and evoke the context and consequences of climate change. A representative of the Academy of Technologies discusses the risks of land-slips and dam failure, outlines that earthquakes only caused some cracks in dams, and evokes the legal context and organisation regarding dam safety. Possible effects of earthquakes in France are discussed. A second part addresses the way natural risks are taken into account in the protection of nuclear installations

    2012-01-01

    The cooling circuits of nuclear power plants, by their mode of operating, can select thermophilic microorganisms including the pathogenic organism Legionella pneumophila. To control the development of this genus, a disinfection treatment of water cooling systems with monochloramine can be used. To participate in the management of health and environmental risks associated with the physico-chemical and microbiological modification of water collected from the river, EDF is committed to a process of increasing knowledge about the ecology of Legionella in cooling circuits and its links with its environment (physical, chemical and microbiological) supporting or not their proliferation. Thus, diversity and dynamics of culturable Legionella pneumophila were determined in the four nuclear power plants along the Loire for a year and their links with physico-chemical and microbiological parameters were studied. This study revealed a high diversity of Legionella pneumophila subpopulations and their dynamic seems to be related to the evolution of a small number of subpopulations. Legionella subpopulations seem to maintain strain-specific relationships with biotic parameters and present different sensitivities to physico-chemical variations. The design of cooling circuits could impact the Legionella community. The use of monochloramine severely disrupts the ecosystem but does not select biocide tolerant subpopulations. (author)

  19. Nuclear Waste Facing the Test of Time: The Case of the French Deep Geological Repository Project.

    Poirot-Delpech, Sophie; Raineau, Laurence

    2016-12-01

    The purpose of this article is to consider the socio-anthropological issues raised by the deep geological repository project for high-level, long-lived nuclear waste. It is based on fieldwork at a candidate site for a deep storage project in eastern France, where an underground laboratory has been studying the feasibility of the project since 1999. A project of this nature, based on the possibility of very long containment (hundreds of thousands of years, if not longer), involves a singular form of time. By linking project performance to geology's very long timescale, the project attempts "jump" in time, focusing on a far distant future, without understanding it in terms of generations. But these future generations remain measurements of time on the surface, where the issue of remembering or forgetting the repository comes to the fore. The nuclear waste geological storage project raises questions that neither politicians nor scientists, nor civil society, have ever confronted before. This project attempts to address a problem that exists on a very long timescale, which involves our responsibility toward generations in the far future.

    The legal French procedures include three steps which have to be followed during the exam of the safety in nuclear plants (creation authorization, loading authorization, actual running of the plant). After listing the different types of evaluation of safety in fraction of plants, this report presents the main themes encountered during the safety assessment: state of the reactor, maintenance, tracking of the incidents, personnel training, radioprotection, radioactive releases. The Fessenheim and Bugey list of reevaluation themes is also given. (TEC).

  1. Project of law authorizing the approval of the agreement between the government of the French republic and the government of the Russian federation relative to the civil liability by way of nuclear damage owing to the supply of materials from the French republic devoted to nuclear facilities in the Russian federation

    An agreement between France and Russia was signed on June 20, 2000 about the civil liability of Russia because of the supply of French material devoted to Russian nuclear facilities. This agreement was necessary because Russia do not belong to any of the two big international civil liability systems relative to nuclear energy, i.e. the Paris convention from July 29, 1960 (in the OECD framework) and the Vienna convention from May 21, 1963 (in the IAEA framework). This agreement offers a protection to the French nuclear suppliers against any damage claims in the case of a nuclear accident occurring on the Russian federation territory. This project of law aims at approving this agreement. (J.S.)

    Steam Generators (SG) usually present important deposit loading and Tube Support Blockage, resulting from Secondary Side corrosion products. These phenomena modify SG behavior which can lead to safety, heat exchange performance and lifetime problems. In this context, a Chemical Cleaning Process (PACCO) was designed to solve the issue. After almost two years of intensive lab tests, pilot simulation and mock-ups, the chemical process was finally qualified by EDF. The aim of the work was firstly the development in laboratory of a chemical process that could eliminate partially the deposit loading, respecting the integrity of materials and gas emission limits. Secondly, the objective was the design and the implementation of the process on-site. The process has been applied successfully in 3 SG in Dampierre nuclear power plant in France on July 2013. The main results were: - Corrosion < 100 μm. - 40% of the initial deposit loading, removed by SG. (authors)

    Chemical durability studies of nuclear glasses involves a large number of water leaching experiments at different temperatures and pressures on both, glasses doped with fission products and actinides and non radioactive surrogates. The leaching rates of these glasses are evaluated through ICPAES analysis of the leachate over time. This work presents a statistical evaluation of the analysis method used to determine the concentrations of various vitreous matrix constituents: Si, B, Na, Al, Ca, Li as major elements and Ba, Cr, Fe, Mn, Mo, Ni, P, Sr, Zn, Zr as minor elements. Calibration characteristics, limits of detection, limits of quantification and uncertainties quantification are illustrated with different examples of analysis performed on surrogates and on radioactive leachates in glove box.

    The accident which occurred at Three Mile Island (TMI 2) on March 28, 1979 is considered rightfully as the outset of the approach taking the human factor explicitly into account in nuclear safety, both in the design of the plants and in their operational use. In this paper, we shall endeavour to explain how this human factor has been taken into account in France. For this purpose, in the first part, we shall define the requirements, i.e. describe the sectors in which improvements were deemed necessary. In the second part, we shall describe the structures set up both at EDF and at the CEA to handle these problems. Lastly, in the third part, we shall describe the principal actions taken or in progress [fr

    The SDIN is the new information system that allows the management of operating and maintenance activities of EDF's fleet of nuclear power plants. This new system relies on 6 main softwares that allow: 1) the management of operations and maintenance, 2) the management of documentation, 3) the management of activities during unit outages, 4) the management of diagrams, schemes and designs, 5) the reporting of activities, and 6) a unified access to the SDIN. SDIN entered into operation in 2012 (6 years after its launching) in a testing phase in the Blayais power plant and in 2 engineering departments. SDIN is expected to improve the plant performance and its standard of safety as well as to prepare the way in terms of adequate technical conditions for operating life extension. (A.C.)

    In case of accident entraining radiological consequences on or near the site of nuclear power reactor, organizations are putting in place. These organizations include as well as side of operating authority (generally Electricite de France) or public organizations including safety organizations (Service Central de Surete des Installations Nucleaires, Institut de Protection et de Surete Nucleaire), one local organization and one centralized national organization. Informations exchange and coordination necessary between these organizations are governed by protocols. These protocols include particularly, the problems of mobilizing experts and of dealing with the saturation of normal telecommunications channels. The lessons acquired during accident simulation exercises carried out in recent years are progressively put in place in these protocols [fr

    1989-01-01

    Sulphur dioxide emissions in France have declined by 64% from 1980 to 1987. Those of nitrogen oxides from stationary sources have been lowered by 49 %. The main reason is the development of nuclear electricity, from 52 000 TJ in 1977 to 894 000 TJ in 1987. Another factor is a better efficiency in energy use: from 1973 to 1987, the Gross Domestic Product has progressed by 33% while energy consumption only increased by 6.7%. Furthermore, natural gas consumption has grown from 360 000 TJ in 1973 up to 878 000 TJ in 1987. France still must abate emissions in the medium and long range, and efforts will essentially bear on small and medium-size combustion plants by direct injection of limestone and lime in the furnace development of various types of desulfurizing fluid bed combustors and flue gas treatment processes [fr

    Over the years, France has built up significant experience in dismantling nuclear fuel reprocessing facilities or various types of units representative of a modern reprocessing plant. However, only small or medium scale operations have been carried out so far. To prepare the future decommissioning of large size industrial facilities such as UP1 (Marcoule) and UP2 (La Hague), new technologies must be developed to maximize waste recycling and optimize direct operations by operators, taking the integrated dose and cost aspects into account. The decommissioning and dismantling methodology comprises: a preparation phase for inventory, choice and installation of tools and arrangement of working areas, a dismantling phase with decontamination, and a final contamination control phase. Detailed description of dismantling operations of the MA Pu finishing facility (La Hague) and of the RM2 radio metallurgical laboratory (CEA-Fontenay-aux-Roses) are given as examples. (J.S.). 3 tabs

    1997-01-01

    In order to improve monitoring and diagnosis capabilities in nuclear power plants, Electricite de France (EDF) has designed an integrated monitoring and diagnosis assistance system: PSAD-Poste de Surveillance et d'Aide au Diagnostic. The development of such a sophisticated monitoring and data processing systems has emphasized the need for the addition of analysis and diagnosis assistance capabilities. Therefore, diagnostic knowledge based systems have been added to the functions monitored in PSAD: DIVA for turbine generators, and DIAPO for reactor coolant pumps. These systems were designed from a representation of the diagnostic reasoning process of experts and of the supporting knowledge. Diagnosis in both systems relies on an abduction reasoning process applied to component fault models and observations derived from their actual behavior, as provided by the monitoring functions. The basic theoretical elements of this diagnostic model are summarized in a first part. In a second part, DIVA and DIAPO specific elements are described

    A graduate workshop was held on Monday 15 May, at the Maison francaise d'Oxford, involving a little group of graduate students, from the UK and France. They were invited to present their research and to engage in discussions over the place of nuclear energy in the context of the social sciences and humanities. Wider issues of relevance and interest regarding nuclear energy - such as its human, cultural and philosophical dimensions - have not received sufficient attention in either France or Britain. A number of specific areas were identified to be significant in this respect: - The need for clearer, 'unbiased' information, explanations and better understanding of the wider human dimensions associated with nuclear energy. - A better understanding of the influences upon, and differences in social attitudes towards nuclear in France and Britain. - The factors influencing varying attitudes within Britain and France amongst different sections of society. Particular references were made to the younger age groups and gender differences. - And understanding of 'changes' of attitude and support found in Britain and France, in more recent times. - The importance of the community, social, cultural, ethical and human dimensions given the unique nature of the nuclear sector, and in particular the long term nature and scale of economic and social investments associated with nuclear energy. - The impact of perceptions about the nuclear risk factors that may, or may not, be very different to reality over time. - The global nature of the impact of the sector on Anglo-French interests and the opportunities for positive collaboration, and learning in the wider human, social, ethical, cultural and philosophical aspects. - The multitude of social media channels available for disseminating information and opinions that influence social attitudes about nuclear energy. - A lack of trust in policy or operational statements emanating from the government, company or

    After recalling the entry of nuclear energy into energy production in France, the paper emphasizes the evolution of techniques applied in the designing of French nuclear power plants and describes the means employed for reducing costs per kWh of EDF2 and EDF3 compared with EDF1: the electric power per ton of uranium varies from 493 kW/t for EDF1 to 970 kW/t for EDF3. For this purpose the thermal power and electric power of units are changed respectively from 290 MWt for EDF1 to 1200 or 1600 MWt for EDF3 and from 28 to 250 MW. The results are obtained by an improvement in neutronic characteristics, developments in nuclear fuel technology, and simplification of the system of charging the reactor, whose means of maintenance are increased; the EDF2 heat-exchangers have been so designed as to increase the unit power of the elements, which will attain 9 MWt, as against 3 for EDF1. For EDF3 an advance project forecasts a thermodynamic layout with only one pressure stage. The paper ends with a description of the burst-slug detection systems, and an appendix gives a detailed comparative table of EDF1, EDF2 and EDF3 plant characteristics.

    1977-01-01

    In the nuclear field, safety reliability methods are fully developing. The applications, which are a part of the system analysis, deal now with accidents - as was demonstrated by WASH-1400 - without neglecting the development of data collecting which is an essential element. International cooperation and exchanges are very fruitful and very open. In France, the builders (mainly FRAMATOME and GAAA) and power plant operators (Electricite de France), and of course safety authorities have developed on common bases numerous studies on reactors being ordered and being built. Joint teams carry out various researches in close cooperation. The application areas include the system analysis to evaluate the system performances and set up operating rules to be applied in the event of the partial unavailability of those systems. The studies dealt with emergency systems and their auxiliaries. Corresponding methods for the analysis of complex systems have been developed as was needed. As far as accidents are concerned, an important point is the systematic search for possible accident initiators, and a method based on the barrier concept and the operation of systems protecting the barriers is being developed, at the same time as the evaluation of accident sequences. Such studies could be used to check system performances, and even to design homogeneously circuits with increased reliability. Accident assessment after evaluation will give a classification by order of importance and will lead to more consistent safety designs. Future studies, always in close cooperation, will deal mainly with: an improved conception of safety tending toward a final technical allocation (such as the probability of core melt-down for the reactor); a refined methodology to meet with this allocation, with a search for common modes of failure, test and maintenance optimization, and the rational decrease of risks and consequences of human errors; the pursuing of present actions for reliability data and

    International Nuclear Information System (INIS)

    Mohammadioun, B.

    1986-06-01

    The methodology put into practice in the analysis of seismic hazard on the site of a nuclear facility relies upon a deterministic approach and endeavors to account for the particularities of every site considered insofar as available data and techniques allow. The calculation of a seismic reference motion for use in the facilities' design calls upon two basic sets of data. Regional seismicity over the past millennium, from historical sources, revised while preparing the seismotectonic map of France, is fundamental to this analysis. It is completed by instrumental data from the last quarter century. A collection of strong-motion accelerograph data from seismic areas worldwide reflects a variety of source characteristics and site conditions. A critical overview of current practice in France and elsewhere highlights shortcomings and areas of particular need both in experimental data and in methodology, and namely the scarcity of near-field data, the predominance of California records, and inaccurate approaches to integrating soil effects into ground-motion calculations. 16 refs

    1988-10-01

    All countries operating nuclear power stations have developed systems for declaring and analyzing incidents occurring when the stations are in service. These systems, are inevitably extensive and complex, as the search for perfection in terms of operating safety leads not only to identification and analysis of incidents which are evidenced by their consequences, but also to identification of all those other incidents which have not had repercussions, but which nevertheless constitute precursor events for more serious situations. For example in France, a system based on safety significance criteria has been in service since the early 1980s, and is applied and operated by EDF and the safety authorities. While experts obtain maximum benefit from this system, public opinion and the relay points constituted by the media are somewhat at a loss, being unable to discriminate in the mass of non-hierarchized information which may come their way, between what is genuinely important and what is less important or even totally unimportant. For this reason, the CSSIN recommended examination of a severity scale, simple to understand and easy to use, which could be employed to classify all incidents and which could become, in due course, as familiar to all of us as the Richter seismic scale is today. We will now examine the composition of this scale, applied on an experimental basis by the Minister for Industry for a period of about one and a half years, as from 20th April 1988

    Although reactor design is mainly governed by deterministic principles in France, the probabilistic approach has been considered an important aid to safety analysis since the early seventies. Various partial probabilistic studies have been performed by Electricite de France, by IPSN and by Framatome, for various types of reactor. In particular, these studies have made it possible to assess the reliability and availability of nuclear power plants safety systems as well as the probability of accident scenarios and have helped to define technical specifications (especially, allowed operating times in the event of a partial unavailability of safety systems). Simultaneously, evaluation methods and corresponding software have been widely developed. Besides. EDF has implemented the Systeme de Recueil de Donnees de Fiabilite - SRDF (Reliability Data Collection System) which allows follow-up of equipment behaviour on all the operating units, and has led to a particularly representative data base. In 1982 the decision was taken at IPSN to carry out a complete PSA for a standard reactor of the 900 MWe type, and in 1986 EDF launched an equivalent study on a 1,300 MWe reactor, taking Unit 3 Paluel as reference. These PSAs were terminated in the course of the first quarter of 1990

    Electricité de France (EDF) currently operates a total of 58 Nuclear Pressurized Water Reactors (PWR) which are composed of 34 units of 900 MWe, 20 units of 1300 MWe and 4 units of 1450 MWe. This report provides an overall status of SG tube bundles on the 1300 MWe units. These units are 4 loop reactors using the AREVA 68/19 type SG model which are equipped either with Alloy 600 thermally treated (TT) tubes or Alloy 690 TT tubes. As of 2011, the effective full power years of operation (EFPY) ranges from 13 to 20 and during this time, the main degradation mechanisms observed on SG tubes are primary water stress corrosion cracking (PWSCC) and wear at anti-vibration bars (AVB) level. Statistical models have been developed for each type of degradation in order to predict the growth rate and number of affected tubes. Additional plugging is also performed to prevent other degradations such as tube wear due to foreign objects or high-cycle flow-induced fatigue. The contribution of these degradation mechanisms on the rate of tube plugging is described. The results from the statistical models are then used in predicting the long-term life of the steam generators and therefore providing a useful tool toward their effective life management and possible replacement.

    Safety reliability methods in the nuclear field are being fully developed. The applications, which are a part of systems analysis, deal now with accidents without neglecting the development of data collecting, which is an essential element. International co-operation and exchange are very fruitful and very open. In France the builders (mainly Framatome and Novatome Industries) and power plants operators (Electricite de France) and of course safety authorities have developed on common bases numerous studies on reactors being ordered and built. Joint teams are carrying out various research projects in close co-operation. The areas of application include systems analysis to evaluate the systems' performance and set up operating rules to be applied in the event of partial unavailability of those systems. The studies dealt with emergency systems and their auxiliaries. Corresponding methods for the analysis of complex systems have been developed as needed. As far as accidents are concerned, an important point is the systematic search for possible accident initiators, and a method based on the barrier concept and the operation of systems protecting the barriers is being developed, in parallel with the evaluation of accident sequences. Future studies, always in close co-operation, will deal mainly with: final technical allocation; common modes of failure, test and maintenance optimization, human errors; the pursuit of action for collecting reliability data and operating experience, and rare events; a regulation that will take into account probabilistic studies, the corresponding methodology, and the associated means of acceptance.

    Controlled amounts of liquid tritium are discharged as tritiated water (HTO) by the nuclear industry into the English Channel. Because the isotopic discrimination between 3H and H is small, organically bound tritium (OBT) and HTO should show the same T/H ratio under steady-state conditions. We report data collected from the environment in the English Channel. Tritium concentrations measured in seawater HTO, as well as in biota HTO and OBT, confirm that tritium transfers from HTO to OBT result in conservation of the T/H ratio (ca. 1 × 10(-16)). The kinetics of the turnover of tritium between seawater HTO, biota HTO, and OBT was investigated. HTO in two algae and a mollusk is shown to exchange rapidly with seawater HTO. However, the overall tritium turnover between HTO and the whole-organism OBT is a slow process with a tritium biological half-life on the order of months. Nonsteady-state conditions exist where there are sharp changes in seawater HTO. As a consequence, for kinetic reasons, the T/H ratio in OBT may deviate transiently from that observed in HTO of samples from the marine ecosystem. Dynamic modeling is thus more realistic for predicting tritium transfers to biota OBT under nonsteady-state conditions.

    1994-01-01

    The study addresses the issue of the impact the forthcoming regulations derived from ICRP 60 recommendations will have on radiological protection practices. A questionnaire has been sent to companies carrying out tasks involving exposures to ionizing radiation. 55 companies reported the exposures of their personnel (annual collective effective dose equivalent and distribution of individual doses). The reference year is 1991. Results were obtained for a total of 43789 workers, with a corresponding collective dose equivalent of 96 man.Sv and 1100 persons with individual dose in excess of 20 mSv (1800 in excess of 15 mSv). The major part of collective, as well as the higher individual exposures are found in subcontract companies involved in maintenance, cleaning and specialized tasks during reactor shutdown. Based on this inquiry, results have been extrapolated to the whole nuclear fuel cycle. 68000 workers are estimated to be exposed, with a total collective dose of 160 man.Sv. Among them 2200 workers would be exposed to dose equivalent in excess of 20 mSv, 3400 in excess of 15 mSv. Even if higher doses concern few people, they are associated with important tasks at particular steps of the fuel cycle. In the questionnaire, companies were asked for ways and means envisaged or already in use to keep these doses within present or tighter regulatory limits. Some account of the efforts to achieve this goal will be given

  3. French PWR Safety Philosophy

    The first 900 MWe units, built under the American Westinghouse licence and with reference to the U. S. regulation, were followed by 28 standardized units, C P1 and C P2 series. Increasing knowledge and lessons learned from starting and operating experience of French nuclear power plants, completed by the experience learned from the operation of foreign reactors, has contributed to the improvement of French PWR design and safety philosophy. As early as 1976, this experience was taken into account by French Safety organisms to discuss, with Electricite de France, the safety options for the planned 1300 MWe units, P4 and P4 series. In 1983, the new reactor scheduled, Ni4 series 1400 MWe, is a totally French design which satisfies the French regulations and other French standards and codes. Based on a deterministic approach, the French safety analysis was progressively completed by a probabilistic approach each of them having possibilities and limits. Increasing knowledge and lessons learned from operating experience have contributed to the French safety philosophy improvement. The methodology now applied to safety evaluation develops a new facet of the in depth defense concept by taking highly unlikely events into consideration, by developing the search of safety consistency of the design, and by completing the deterministic approach by the probabilistic one

  4. Resolution proposal for the creation of an inquiry commission about the safety and transparency risks generated by the opening of the capital and the privatization of the French nuclear industry

    International Nuclear Information System (INIS)

    2004-12-01

    The privatization of the French nuclear industry leads to three types of risks: the dilution of decision prerogatives (need of long-term investment for maintenance and safety purposes which are incompatible with immediate profits), incompatibility between private control and safety, and speculation (need of stable and durable financing for a sustainable safety). For these reasons, the French house of commons has created an inquiry commission about the safety and transparency risks linked with the capital opening and privatization of the French nuclear industry.

    In a first article, after having recalled the present situation of the French energy mix, the author analyses the consequences of the shutting down of 22 nuclear reactors by 2025 to bring the nuclear share down from 75 to 50 per cent. Different options are discussed: fossil energy (but CO 2 emissions would be impacted), renewable energy (hydroelectricity cannot be further developed, biomass can be useful for heat networks, and wind energy is limited). The author examines the possibilities of decreasing electricity consumption, and of a significant contribution of gas plants. He compares direct gas- and fuel oil-based heating with heating with electricity produced by gas plants. A second article addresses the issue of renewal of the French nuclear reactor fleet. It discusses how to choose the right renewal pace, and an assessment of exploitation losses

    The Centre de l'Aube Disposal Facility (Centre de Stockage de l'Aube) is designed to receive a wide variety of waste produced by nuclear power plants, reprocessing, decommissioning, as well as the industry, hospitals and armed forces. Such a variety of wastes incur highly different risks which must be grasped in the safety analysis of the Centre. This article attempts to show how a number of safety analysis tools are used to meet the highly varied needs of the waste producers and guarantee safe disposal. They involve functional analysis, risk analysis and safety calculations. The paper shows that the most important acceptance criteria for the first containment barrier, namely the waste package, are containment, durability, activity limitation and biological shielding. And a method is proposed to determine some of these criteria from safety scenarios (scenarios of accidents in operation, intrusion in the post-institutional control phase). Over the years, however, the waste producers have asked the Agence Nationale pour la Gestion des Dechets Radioactifs (ANDRA) to accept new types of waste not initially anticipated in the design criteria, and the safety analysis must imagine new scenarios and develop new acceptance criteria. The paper gives the example of sealed sources, closure heads of NPP vessels, racks for fuel elements, contaminated manipulators, irradiating waste, etc, which incur specific risks. In fact, some of this waste represent a source of unusual irradiation, a risk of further contamination in an accidental situation, or simply increase the likelihood of occurrence of certain scenarios, such as retrieval in the post-institutional control phase. The safety analysis must adapt and imagine specific scenarios to judge the acceptability of such waste, and must identify the acceptance criteria commensurate with the risks. The paper offers examples of research, some of it still under way at ANDRA. (author)

  7. IRSN's viewpoint on the safety and radiation protection of French nuclear power plants in 2007

    This report presents the viewpoint of the IRSN on the safety and radiation protection of EDF's nuclear power plants (NPPs) in operation during 2007. It does not aim to be exhaustive but rather to highlight the points the IRSN considers important for safety. Contributing to maintaining a high level of safety and radiation protection in nuclear facilities in service is one of the seven challenges of the objectives contract signed between the French Government and the IRSN. Safety demands constant vigilance on the part of all the players involved. It is never definitively acquired and must remain a priority and continuously progress, with the plant operator remaining the first entity responsible for the safety of its facility. For the IRSN, part of this mission firstly involves carefully examining and taking into consideration national and international experience feedback, and new scientific knowledge resulting from research. The implementation of improvements, whether technical or organizational or relating to human skills, then comes secondly. This report comprises four sections. In the first section, the IRSN presents the main trends that emerged from its overall review of the safety of the in-service nuclear power plants. The second section addresses the events that have marked the year due to their impact on safety. It also presents a synthesis of the radiation protection events. The third section is devoted to anomalies displaying a generic nature for several power plants. The last section covers the significant changes implemented or scheduled. These are generally modifications or plans of action intended to improve safety performance in the operation or design of the facilities. In spite of sometimes significant disparities in the results between power plants, the IRSN draws the following conclusions from its global review of the year 2007. First of all, no event had serious consequences in the fields of either safety or radioprotection. This good result

    French nuclear workers have detailed records of their occupational exposure to external radiation that have been used to examine associations with subsequent cancer mortality. However, some workers were also exposed to internal contamination by radionuclides. This study aims to assess the potential for bias due to confounding by internal contamination of estimates of associations between external radiation exposure and cancer mortality. A cohort of 59,004 workers employed for at least 1 year between 1950 and 1994 by CEA (Commissariat a l'Energie Atomique), AREVA NC, or EDF (Electricite de France) and badge-monitored for external radiation exposure were followed through 2004 to assess vital status and cause of death. A flag based on a workstation-exposure matrix defined four levels of potential for internal contamination. Standardized mortality ratios were assessed for each level of the internal contamination indicator. Poisson regression was used to quantify associations between external radiation exposure and cancer mortality, adjusting for potential internal contamination. For solid cancer, the mortality deficit tended to decrease as the levels of potential for internal contamination increased. For solid cancer and leukemia excluding chronic lymphocytic leukemia, adjusting the dose-response analysis on the internal contamination indicator did not markedly change the excess relative risk per Sievert of external radiation dose. This study suggests that in this cohort, neglecting information on internal dosimetry while studying the association between external dose and cancer mortality does not generate a substantial bias. To investigate more specifically the health effects of internal contamination, an effort is underway to estimate organ doses due to internal contamination.

    1989-01-01

    Power evacuation and feeding of the auxiliaries directly from the 400 kV grid are sensitive points governing the security of 1300 MW PWR Nuclear Power Plants of the French Program. These two different functions are provided by two specific types of transformers. - Banks of 3 single-phase 550 MVA - 400 kV/20 kV transformers. - Three-phase 96 MVA - 400 kV / 3 x 6.8 kV transformers. These passive elements must have a never failing reliability and assure a continuous service in spite of electric, thermal and mechanical stresses that may occur during the lifetime of the power plant. Dielectric and thermal tests carried out in the manufacturers test floors insure these stresses withstand capabilities of transformers. In France, high short-circuit power for the 400 kV network added to often low impedance voltages for transformers impose on them very high stresses during short-circuits. Calculation and experimentation on scale or partial models are not sufficient to insure short-circuit currents withstand capabilities of transformers. The margin of uncertainty dependent on obligatory extrapolations for this kind of complex systems [steel, magnetic sheets, copper, oil, paper and transformerboard] can be reduced in a significant way only by real scale tests on prototypes. These tests that need both high power and voltage cannot be performed in manufacturers test floors. So, in France they are carried out at the EDF Les Renardieres Laboratory. Following paper deals with SHELL TYPE TRANSFORMERS which, particularly thanks to their interleaved rectangular windings display a great resistance to short-circuit stresses

  11. Geochemical modelling of the long-term dissolution behaviour of the French nuclear glass R7T7

    1992-01-01

    The long-term dissolution behaviour of the French nuclear reference glass R7T7 was studied by means of the geochemical code DISSOL. New experimental data which support some of the assumptions of DISSOL are presented: namely, that the dissolution is congruent and that the altered layer can be considered as an assemblage of secondary phases. At 100 o C the main results of modelling are that the altered layer is essentially formed of a pure siliceous phase (amorphous silica or chalcedony) associated with smectites and zeolites. This sequence of secondary minerals is closely linked to the chemical composition of the glass. For high degrees of reaction, corresponding to high B concentration, the ionic strength reaches 1 and the pH varies from 9 to 10 depending on the CO 2 fugacity; B,Li and Na are essentially found in solution and their concentrations depend on the amount of dissolved glass. By contrast Fe,Al and Zn have low solution concentrations which are controlled by solubility products of secondary minerals. Silicon and Ca have an intermediate behaviour which depends on the choice of selected secondary minerals. The total volume of the secondary phases is always lower than that of the corresponding dissolved glass. The results of modelling compared to static leaching experimental results show only minor differences which can be explained by kinetic control or colloid formation. It is concluded that the altered layer is not a barrier to diffusion. The consequences of this work for actinide solubility are also discussed. (author)

    2001-01-01

    France has to face strong energy challenges: a heavy energy bill, increasing supplies risk, no decreasing CO 2 emissions, deregulation of energy markets, nuclear controversy etc.. In consequence, the French government has defined a voluntaristic energy policy with a better balance between the development of renewable energies and the mastery of energy and without renouncing the advantages of nuclear energy. In parallel, the electric power and natural gas industries have to cope with the deregulation of energy markets and the resulting competition. This issue of 'Energies et Matieres Premieres' newsletter comprises 3 articles. The first one gives a general presentation of the French energy policy ('mobilizing our margins of manoeuvre without renouncing our stakes'): challenges of the energy policy (greenhouse effect, security of supplies, long-term worldwide energy context, European integration, nuclear contestation), stakes for France (evolution of production structure, advantages of the French energy status), renewable energies and energy saving, long-term view of the nuclear industry, managing together the dynamism of competition and the advantages of public utilities. The second article entitled 'energy for everybody: a challenge for the 21. century' is a reprint of the introduction of the information report registered on January 31, 2001 by the commission of production and exchanges of the French national assembly. The third article is a reprint of the summary of conclusions and recommendations of the IEA about the French energy policy. (J.S.)

    The 1991 Radioactive Waste Management Act established a framework in France for research activities on nuclear waste. Within this context, the Commissariat a l'Energie Atomique initiated a research program in 1999 to investigate the long-term behaviour of commercial spent nuclear fuel under the PRECCI project (from the French acronym for Research Project on Long-Term Evolution of Spent Fuel Packages), supported by the French electrical utility EDF and partially by FRAMATOME ANP. The scientific and technical studies performed within the project aim to address the operational issues of the spent fuel end-of-life. Within the context of the law which ends in 2006, the major part of the studies focused on the behaviour of the spent fuel (SF) in interim long-term dry storage and deep geological disposal. The operational questions initially identified concern (i) the retrievability of spent fuel assemblies at the end of the interim period of storage, (ii) the feasibility of treatment after the period of storage, (iii) the radionuclide source terms for SF in storage and geological disposal and (iv) the compatibility between storage and a subsequent geological disposal. Therefore the long-term evolution of the irradiated fuel is studied under the various boundary conditions encountered during storage and geological disposal: - in a closed system; this condition corresponds to the nominal scenario during storage and to the first confinement phase in disposal conditions (with a duration of 10,000 years in the reference scenario); - it consists in assessing the effects of the residual temperature and high radioactivity on the chemical and physical properties of the spent fuel pellets; - some of the studies are also dedicated to the mechanical behaviour of the cladding and structural materials of the assemblies; - in air, it refers to an incidental loss of confinement during storage or to a breaching of the canister before the site re-saturation in geological disposal

    The challenge of the oil crisis made French energy policy react chiefly by means of a programme for the rapid expansion of nuclear energy which has become unparalleled because of its systematic realization. The following article gives a survey of this programme and its political preconditions. The French energy programme deserves special attention as the utilization of nuclear energy in France including all related activities has reached a more advanced stage than in most other countries. The effects and requirements connected with such an extensive programme which can therefore be investigated with the help of the French example migth be of importance also for other countries in a similar way.

    During inductive plasma operation of ITER, fusion power will reach 500 MW with an energy multiplication factor of 10. The heat will be transferred by the Tokamak Cooling Water System (TCWS) to the environment using the secondary cooling system. Plasma operations are inherently safe even under the most severe postulated accident condition a large, in-vessel break that results in a loss-of-coolant accident. A functioning cooling water system is not required to ensure safe shutdown. Even though ITER is inherently safe, TCWS equipment (e.g., heat exchangers, piping, pressurizers) are classified as safety important components. This is because the water is predicted to contain low-levels of radionuclides (e.g., activated corrosion products, tritium) with activity levels high enough to require the design of components to be in accordance with French regulations for nuclear pressure equipment, i.e., the French Order dated 12 December 2005 (ESPN). ESPN has extended the practical application of the methodology established by the Pressure Equipment Directive (97/23/EC) to nuclear pressure equipment, under French Decree 99-1046 dated 13 December 1999, and Order dated 21 December 1999 (ESP). ASME codes and supplementary analyses (e.g., Failure Modes and Effects Analysis) will be used to demonstrate that the TCWS equipment meets these essential safety requirements. TCWS is being designed to provide not only cooling, with a capacity of approximately 1 GW energy removal, but also elevated temperature baking of first-wall/blanket, vacuum vessel, and divertor. Additional TCWS functions include chemical control of water, draining and drying for maintenance, and facilitation of leak detection/localization. The TCWS interfaces with the majority of ITER systems, including the secondary cooling system. U.S. ITER is responsible for design, engineering, and procurement of the TCWS with industry support from an Engineering Services Organization (ESO) (AREVA Federal Services, with support

  20. French Foodscapes

    DEFF Research Database (Denmark)

    Hedegaard, Liselotte

    By exploring how local and regional products and uses of food interact with the changes in the French cuisine over time, this paper seeks to retrace the history of the French meal through meanings of place and time, terroir and savoir-faire. The study will be based on sources from early modern/modern history...... the destructuralisation of eating habits have been raised since the 1980s, but numerous studies emphasise that the traditional French meal is still playing an important role in everyday life in France. Despite regional variations, the general view of the structure of a traditional French meal as based on the succession...... of flavours and the accordance with wines is widespread. Such a comprehension means giving precedence to gastronomic reasons for determining the order of dishes. However, the French meal has not always been composed in the way it is today and the reasons for the composition have not always been gastronomic...

    NONE

    2008-03-15

    The present proposition of law has for object to answer the expectation of all the persons who have participated as military personnel or civilians in nuclear tests made by France between February 13., 1960 and January 27., 1996, or lived near the nuclear test sites of Sahara (Reggane) or in French Polynesia. The same pathologies are noticed among the veteran or the populations having lived near the nuclear tests sites of the other nuclear countries which made the same experiments. It is the case in United States, in Great Britain, in Australia, in New Zealand and in Fidgi. In these different countries having a democratic system similar to ours, the governments took concrete measures to accede to the demands of their nationals. It thus turns out that a legislative initiative would represent a strong message of gratitude towards all those who had to undergo aftereffects on their health and that of their descendants of the only fact of their participation in the nuclear experiments of France.

  3. Specific outcomes of the research on the radiation stability of the French nuclear glass towards alpha decay accumulation

    This paper presents an overview of the main results of the French research on the long-term behavior of SON68 nuclear glass towards alpha decay accumulation. The effect of the radiation damage induced by alpha decay and also helium build-up were investigated by examining glass specimens, doped with a short-lived actinide 244Cm, irradiated by light and heavy ions. Additionally, atomistic simulations by molecular dynamics have provided further information on the atomic-scale effects of the macroscopic phenomena observed. These studies have shown that some macroscopic properties vary with the accumulation of alpha decay, but then stabilize after integrated doses of the order of 4 × 1018 α g-1. For example, the glass density diminishes by about 0.6%, its Young's modulus by about 15%, and its hardness by about 30%, while its fracture toughness increases by around 50%. The SEM and TEM characterization showed that the glass is still homogeneous. No phase separation, crystallization or bubbles formation was noticed up to an alpha decay dose corresponding to several thousand years of disposal of nuclear glass canister. Moreover the initial alteration rate of the glass is not significantly affected by the glass damage induced by alpha decays or heavy ions irradiations. The comparison of the macroscopic evolutions of the Cm doped glass with those obtained for glasses irradiated with light or heavy ions (from either experimental and molecular dynamic studies) suggests that the macroscopic evolutions are induced by the nuclear interactions induced by the recoil nuclei of alpha decay. The analysis of the behavior of the glass structure subjected to ballistic effects with various spectroscopic studies, together with the results of atomistic modeling by molecular dynamics, have identified some slight changes in the local order around some cations. Moreover a modification of the medium-range order has also been demonstrated through changes in the bond angles between network

    The French Nuclear Society is calling for the following actions at the EU level: Revitalize EURATOM R and D around a common ambition from the group of countries engaged in nuclear energy: The European Commission, the 'guardian of the Treaties', must fully implement the EURATOM Treaty provisions. The first objective set in Article 2(a) of the Treaty is to 'promote research'. Chapter I of the Treaty is dedicated to R and D and Article 4 tasks the Commission for 'promoting and facilitating nuclear research in the Member States and for complementing it by carrying out a Community research and training programme'. R and D on nuclear fission reactors and on the fuel cycle is necessary to strengthen the European industry's technological leadership. New governance practices must be negotiated with countries that do not wish to use nuclear energy in their future energy mix, including Germany, so they do not block initiatives around the development of nuclear energy. Countries wishing to use nuclear power should be able to fully use the provisions of the EURATOM Treaty for the implementation of common objectives. The EU must include and champion nuclear research, such as the United States, Canada and the United Kingdom do, in the intergovernmental initiative 'Mission Innovation' (commitment to double public investment in clean energy research and development in the next five years), developed within the framework of the United Nations Convention against Climate Change. Re-launch European research on new concepts of fission reactors: The EU has gradually withdrawn from research on new fission reactors. It allocated only 316 million euros to nuclear fission over 2014-2018, focusing on issues of safety, radiation protection and waste management, and ignoring future fission reactors. This compares with the euros 5.9 billion allocated over 2014-2020, (more than 10 times more) under Horizon 2020 in its 'Secure, Clean and Efficient

    This paper points out the inventive properties of the frenchctors G2 and G3. These are dual purpose reactors, i.e. designed for the production of both plutonium and energy (30 electrical MW); in this respect, they can be considered as the start point of the french electrical energy produced from nuclear fuel. The following points are specially discussed in this paper: the choice of the prestressed concrete pressure vessel, the horizontal arrangement of the channels, the interest of neutron flux flattening, the advantages of the charging and discharging device working during pile operation.

    2001-01-01

    4-, 5- and 6-oxide components alumino-borosilicate glasses, with compositions closed to the matrix of the french nuclear glass 'R7T7' have been irradiated with electrons (β) at 2.5 MeV with a Van de Graff accelerator. These glasses have been studied after irradiation with different spectroscopic methods: Electron Paramagnetic Resonance for the study of defects, Raman Micro-spectroscopy for the study of amorphous network evolution under irradiation, and by 11 B MAS NMR. The results of these studies are presented here. It shows in particular a great sensibility to the irradiation conditions like dose rate and irradiation temperature, who are therefore important parameters for the representativeness of such experiments.

    2014-12-01

    This article discusses the availability and completeness of medical data on workers from the AREVA NC Pierrelatte nuclear plant and their possible use in epidemiological research on cardiovascular and metabolic disorders related to internal exposure to uranium. We created a computer database from files on 394 eligible workers included in an ongoing nested case-control study from a larger cohort of 2897 French nuclear workers. For each worker, we collected records of previous employment, job positions, job descriptions, medical visits, and blood test results from medical history. The dataset counts 9,471 medical examinations and 12,735 blood test results. For almost all of the parameters relevant for research on cardiovascular risk, data completeness and availability is over 90%, but it varies with time and improves in the latest time period. In the absence of biobanks, collecting and computerising available good-quality occupational medicine archive data constitutes a valuable alternative for epidemiological and aetiological research in occupational health. Biobanks rarely contain biological samples over an entire worker's carrier and medical data from nuclear industry archives might make up for unavailable biomarkers that could provide information on cardiovascular and metabolic diseases.

  10. Evolutionary approaches for the safety evaluation of the nuclear fuel cycle facilities: lessons learnt from french experiences and assessment of future challenges

    International Nuclear Information System (INIS)

    Greneche, D.

    2007-01-01

    This paper is aimed at presenting the recent work carried out in France on the evolution of the safety of the nuclear fuel cycle facilities (FCF). 5 main categories of FCF have been dealt with in this article: uranium conversion, uranium enrichment, fresh fuel fabrication (including Mox fuel), spent fuel storage, and spent fuel reprocessing. The specific of FCF are reviewed and it appears that FCF have generally a safety advantage over reactors: the relatively slow evolution of physico-chemical phenomena causing severe accident conditions. Generally speaking, nuclear safety is ensured through the combination of actions taken at 4 levels: design, implementation, operation and inspection. It must be underlined that the French safety analysis process is primarily based on a deterministic approach (itself based on the fundamental principle of defense-in-depth), supplemented if necessary with probabilistic safety assessment (PSA) to detect potential weak points in a nuclear facility. All this process is well implemented in reactors but in the case of FCF it is generally limited to the deterministic approach. It is showed that the approaches and general principles implemented in the safety analysis of reactors apply well to FCF but the probabilistic analysis of safety remains nevertheless little practiced in FCF for which they still require significant developments.

    Although the event which occurred at the Blayais site on December 27, 1999 did not lead to a dangerous situation for the local population or the environment, it clearly demonstrated the possible occurrence of modes of degradation of the safety level affecting all the units at a site. As a result, a number of projects were established by the French and German operators that were designed to extract useful lessons concerning the flooding risks at the Blayais site, as well as to upgrade all sites equipped with pressurized water reactors, both in France and Germany. This report presents, on the basis of the circumstances observed at the Blayais site during the course of the flood event of December 27, 1999 (which was the subject of a presentation by IPSN at the Eurosafe 2000 Conference), an evaluation of the initiatives aimed at improving the safety of both the French and the German units from an external flooding risk perspective. The safety approaches used in both countries have not been compared. (authors)

  13. The french energy policy

    International Nuclear Information System (INIS)

    1991-01-01

    This book describes french energy policy from 1973 oil crisis till 1992. In a first part, energy consumption, domestic primary energy production, trend of independence energy ratio and costs of petroleum imports in France are presented. In a second part, long-term energy prospects and new axis of energy policy are given: trends of french energy needs, progressive substitution of fossil fuels by nuclear energy and hydroelectric power, energy policy in Common Market and cooperation with eastern Europe. In a third part, energy demand and supply are studied: energy conservation policy in housing, transport and industrial sector is developed. Power generation policy is focused on two main stakes: the choice of investments and nuclear power plants programming, the quality of electric power and the development of efficient uses and exports. A diversification between coal petroleum and natural gas is led. After the fall of petroleum prices in 1986, renewable energies have lost their competitiveness, fire wood occupies a significant place

    On 19 April 1946 the French national assembly passed a law for nationalizing the mineral fuel industry by a vote of 516 against only 31. 'Charbonnages de France' (CDF), the French coal board, was created and prospects were promising. During the reconstruction period (1945 - 1960), coal industry was a pillar of the French economy, the production of coal had been steadily growing to reach its top in 1958 with 59 Mt. The sixties showed the beginning of the decline of coal to the benefit of oil, natural gas and later nuclear energy. As early as 1967 CDF had a policy of promoting new industries in regions of mines in order to break down the mono-industry scheme and to favor staff conversion massively. In 1947 the number of people on the payroll of CDF was 360.000, this number was decreasing steadily to reach 23.000 in 1990. In 2004 the last deep mine to work in France was closed down. This article tells the story of coal mining in France by describing its ups and downs and by assessing its social impact

  19. 3. French national report on implementation of the obligations of the Convention on nuclear safety - Issued for the 2005 Peer review meeting

    International Nuclear Information System (INIS)

    2004-01-01

    The Convention on Nuclear Safety, hereinafter referred to as 'the Convention', is one of the results of international discussions initiated in 1992 with the aim of proposing binding international obligations regarding nuclear safety. France signed the Convention on 20 September 1994, on the first day it was opened for signature on the occasion of the General Conference of the IAEA. France approved the Convention on 13 September 1995 and it entered into force on 24 October 1996. For many years, France has been participating in international initiatives to enhance nuclear safety and considers the Convention on Nuclear Safety to be an important step in this direction. The areas covered by the Convention have long been part of the French approach to nuclear safety. This report, the third one of its kind, is issued in compliance with Article 5 of the Convention on Nuclear Safety and presents the measures taken by France to meet each of the obligations of the Convention. As such, the Convention on Nuclear Safety applies to nuclear power reactors and so most of this report deals with measures taken to ensure their safety. However, for this third report, a number of considerations led France also to present the measures taken concerning all research reactors, with a 'graded approach' tailored to their size where appropriate. First of all, research reactors are subject to the same general regulations as power reactors with regard to nuclear safety and radiation protection. Furthermore, the most powerful research reactor, which is also intended for producing power, was already included in the previous French report. Secondly, within the first report under the Joint Convention on the safety of spent fuel management and on the safety of radioactive waste management, to which France is a party, the measures taken for research reactors in these areas were already presented. Finally the IAEA Board of Governors, on which France has a seat, in March 2004 approved the Code of

  2. National preparedness guide for exiting the emergency phase subsequent to a nuclear accident causing moderate, short-term release on French soil - working document, version 0, May 2010

    International Nuclear Information System (INIS)

    2010-05-01

    This National Guide provides basic explanations and methods to assist in drawing up a local plan for the emergency phase way-out, subsequent to a nuclear accident of moderate magnitude causing short-term (under 24 hours) radioactive release, which could possibly occur in France. The accident situations considered in this Guide have little likelihood of arising and are representative of environmental contamination accidents that might occur at French nuclear facilities covered by a special intervention plan (plan particulier d'intervention, PPI). Such accidents may cause environmental contamination warranting action for post-accident impact management within a range of ten to fifty kilometres from the accident site. To provide some perspective, the accidents considered here would be classified Levels 3, 4 or 5 (incidents or accidents causing release into the environment) on the INES scale customarily used to help the public and media to immediately understand the severity of an incident or accident in the nuclear field. This Guide was drawn up subsequently to the work carried out by the Steering Committee on Post- Accident Phase Management in the Event of a Nuclear Accident or Radiological Emergency Situation (CODIRPA), instituted by the French Nuclear Safety Authority (ASN) in June 2005, and in charge of setting out the basic principles underlying the management of nuclear post-accident situations. This version of the Guide shall be updated on the basis of the operating experience feedback received on its use. The Guide is a planning tool, intended for the Prefectures of department where a basic nuclear facility PPI has been instituted. Its purpose is to enable Prefects to plan and effectively conduct preparedness measures at the local level with the aim of winding down the emergency phase, actively involving all of the relevant actors for this purpose. The exit period from the emergency phase is defined as extending approximately one week from the end of the

  4. Post-Fukushima additional safety assessments: behaviour of French nuclear installations in case of extreme situations and relevance of improvement propositions

    International Nuclear Information System (INIS)

    2011-01-01

    After the Fukushima accident, additional safety assessments (ECS, evaluation complementaire de securite) have been commissioned to assess the resistance of French nuclear installations to extreme scenarios (earthquake, loss of electricity supply, and loss of cooling sources). This report is a synthesis of a more important one. It briefly describes the international context and notices that, in foreign countries, only power reactors are submitted to such additional safety assessments. It describes the approach adopted by the IRSN by considering that severe accidental situation are possible and may have characteristics exceeding the current referential. This approach enables the identification of safety functions which must maintained in these situations, and of some limitations of the current safety referential. The report then discusses the current status of installations, notices that actions are to be performed. It comments the results obtained in terms of installation robustness with respect to risks of earthquake or flooding, or those associated with other external hazards. It comments the analysis performed in case of total loss of cooling sources or of energy supplies in power reactors, in the EPR, and in some other nuclear installations (ILL, CEA's installations, AREVA's laboratories and factories). It finally comments the ability of operators in managing a crisis situation under these conditions, and briefly evokes the subcontracting issue

    2014-01-01

    This report first proposes an overview of the lifetime extension problematic (PLEX) for nuclear plants in a general context (strategy of lifetime extension, and uncertainty and lack of return on experience), and in the case of France (emergence of a strategy of lifetime extension, economic challenges of an extension, uncertainty on investments required by an extension, risk of imposed implicit decisions). It gives a rather detailed overview of the French nuclear reactor fleet, of the status of EDF-operated reactors (construction stages, main lifetime events, regulatory situation of currently exploited reactors) and of their characteristics (common operation principle, main components, main safety functions, main considered severe accidents). It addresses safety issues related to ageing and to the post-Fukushima re-assessment (problematic, robustness increase, limits and weaknesses of additional safety assessments). It presents the currently performed improvements (safety referential, applicable strengthening requirements like safety re-examinations and requirements introduced after Fukushima, applied strengthening prescriptions drawn from additional safety assessments or from the third decennial inspection, with their limitations and perspectives). It proposes strengthening scenarios along with their challenges (in terms of requirement level, procedure and agenda). Three scenarios are proposed (degraded safety, preserved safety, strengthened safety) and analysed in terms of protection against aggressions, diffuse robustness, prevention and management of reactor accident, prevention and management of pool accidents, ultimate control and assistance means. Scenarios are finally compared in terms of costs

    An important program is currently in progress at several laboratories over the world for the development of sensitive, practical non-destructive assay techniques for the quantification of low level transuranics (TRU) in solid wastes. The wide variety of materials and contaminants, the low concentrations and large volumes involve, all make this kind of assay a complicated affair. Over the last few years, considerable progress has been made in the field of assay techniques for low level contaminated wastes. This report describes the methods being developed at French Atomic Energy Commission (C.E.A.) in Cadarache to assay high density TRU waste packages by using photon, neutron or both photon and neutron as interrogating particles. All of these particles are produced by using a pulsed electron linear accelerator from which the photons are produced following Bremsstrahlung phenomena on a heavy metallic converter and the neutrons are generated in appropriate low level photoneutron threshold target (e.g. Beryllium). The dynamic of photonuclear interactions and photoneutron production, use of an electron linear accelerator as a particle source, experimental and electronics details, experimental results, simulation to experiment performances and future experimental and theoretical studies are discussed.

    A study of the corrosion of a borosilicate nuclear glass shows the strong effect of the pH on the dissolution mechanism. Acidic media lead to selective extraction of the glass modifier elements (Li, Na, Ca) as well as B, while dissolution is congruent under alkaline conditions. The silica dissolution rate significantly increases with increasing pH [fr

  9. Organic tritium in freshwater ecosystems: long-term trends in the environment of French nuclear power plants

    2011-01-01

    From 1977 to 2009, more than 600 measurements of organic tritium were performed on fish, aquatic plants and sediments upstream and downstream of the 15 French NPP located along rivers. Examination of the results shows that organic tritium activities have exponentially decreased over the last thirty years, in all components of aquatic ecosystems. Upstream of all NPP, OBT levels in sediments are higher than in plants and fish, themselves larger than HTO in surface water. The magnitude of these differences and the long-term trends depend on the river basin and can be explained by the varying nature of tritium sources. In river catchment, where atmospheric test fallout is the main source of tritium, the observed levels result from the exposure of aquatic organisms to two distinct tritium pools of different ages: atmospheric tritiated water (representing present fallout), and organic tritium from soils (formed over several decades) which supplies particulate matter to surface waters. In the Rhone and Rhine river basins, an additional source of organic tritium of very low bio-availability, probably originating from the luminescent paint industry, is responsible for the spiking of sediment organic matter up to 100 to 100 000 Bq.L -1 combustion water. The comparison of upstream and downstream NPP tritium levels shows that the influence of tritium discharges is detectable only in rivers, with low background OBT activities, i.e in basins other than the Rhone and Rhine. The observed increase in plant and fish OBT is lower than the added HTO activity in water due to discharge, which supports the absence of bioaccumulation for tritium originating from HTO and the absence of highly bio-available tritiated organic molecules in NPP discharges.

    2010-01-01

    The Nuclear Transparency and Security Act 2006-686 of 13 June 2006 (TSN Act) reinforces the integrated approach to nuclear safety, radiation protection and environmental concerns. The TSN Act guarantees 'the public's right to reliable and accessible information on nuclear security' (Article 1). ASN fosters the implementation of this information right. Concerning the environment, it ensures that the available information is accessible and shared. This concern applies first to its own information media and actions, but also to the stakeholders. ASN makes sure that the licensees fulfill the transparency duty required by the TSN Act and is watchful concerning the effectiveness of means implemented for the public access to information. ASN also promotes good practices in its annual report for the public information. With regard to the environment, ASN actions are primarily focused on limiting and supervising the effluents discharges resulting from nuclear activities; monitoring radioactivity in the environment; and preventing and managing emergency situations. One of the recent significant contributions to providing the public with reliable, centralized information is the launch of www.mesure-radioactivite.fr. This web-site issued by the national network under the aegis of ASN, gives the public access to the results of radioactivity measurements carried out by certified laboratories. ASN seeks to involve the public in projects with an important impact on the environment. It considers the Local Information Committees (CLI) as an important contributor to the 'ecological democracy' and invites periodically their representatives to take part in ASN inspections. ASN also encourages public debates. Besides, this is one of the axis of its strategic plan 2010-2012. (author)

    2018-03-01

    This publication reports an analysis of the different parameters which make the nuclear option available for France by 2050. It aims at identifying the production cost of new nuclear production means, at identifying levers for action regarding building and financing to reach a sustainable competitiveness of the sector. This note is based on returns on experience from other industries and also on current EPR constructions in France, Finland and China. Thus, it focuses on third generation EPR. It discusses difficulties met during the first projects, states that managing the production is possible through the development of an industrial program, outlines the role of the State. The second part proposes a technical note which discusses building costs and delays of third generation reactors, outlines the importance of the building cost in the total electric power generation cost, shows that (based on an analysis of past building costs for second generation reactors) building costs can be mastered, discusses the expected evolution of EPR costs, evokes other factors influencing the kWh price, discusses the burden of investment financing in front of risks, discusses how to reduce market risks in order to attract investors (reform of carbon price, long term contracts for low carbon projects), and finally comments the consequences for the future nuclear investment which is required to renew the fleet

    Studies of nuclear workers make it possible to directly quantify the risks associated with ionizing radiation exposure at low doses and low dose rates. Studies of the CEA (Commissariat à l'Energie Atomique) and AREVA Nuclear Cycle (AREVA NC) cohort, currently the most informative such group in France, describe the long-term risk to nuclear workers associated with external exposure. Our aim is to assess the risk of mortality from solid cancers among CEA and AREVA NC nuclear workers and its association with external radiation exposure. Standardized mortality ratios (SMRs) were calculated and internal Poisson regressions were conducted, controlling for the main confounding factors [sex, attained age, calendar period, company and socioeconomic status (SES)]. During the period 1968-2004, there were 2,035 solid cancers among the 36,769 CEA-AREVA NC workers. Cumulative external radiation exposure was assessed for the period 1950-2004, and the mean cumulative dose was 12.1 mSv. Mortality rates for all causes and all solid cancers were both significantly lower in this cohort than in the general population. A significant excess of deaths from pleural cancer, not associated with cumulative external dose, was observed, probably due to past asbestos exposure. We observed a significant excess of melanoma, also unassociated with dose. Although cumulative external dose was not associated with mortality from all solid cancers, the central estimated excess relative risk (ERR) per Sv of 0.46 for solid cancer mortality was higher than the 0.26 calculated for male Hiroshima and Nagasaki A-bomb survivors 50 years or older and exposed at the age of 30 years or older. The modification of our results after stratification for SES demonstrates the importance of this characteristic in occupational studies, because it makes it possible to take class-based lifestyle differences into account, at least partly. These results show the great potential of a further joint international study of

    Published 8 months after the Fukushima Dai-ichi accident, this special issue of Le Monde newspaper takes stock of the nuclear question. Prior to the Fukushima accident, the civil nuclear industry experienced two other major accidents: Three Miles Island (US, 1979) with limited and controlled impacts, and Chernobyl (USSR, 1986) with enormous impacts. The recent Japanese catastrophe has revived the questions concerning this risky technology. However, according to the IAEA, the civil nuclear energy should continue to develop in the future but in a more moderate way. Germany announced in June 2011 the shutdown of its last reactor by 2022, while France remained an exception until the Fukushima accident with a large political consensus among the general public in favor of nuclear energy. The nuclear phasing out or the energy transition is a complex question which is explored in this special issue. Content: 1 - The nuclear world: a moderate growth of the nuclear industry; interview of Mohamed ElBaradei, former head of IAEA; 441 reactors in operation in the world in January 2011; France has chosen the all-nuclear option; critics: a 'costly, unadapted, useless' nuclear program; interview of Valery Giscard d'Estaing, former French President; the nuclear industry actors; nuclear dismantling: a what cost?; how to manage the 250.000 tons of spent fuels; 2 - A risky technology: radioactivity measurement and effects; how to manage contaminations; four generations of reactors; ITER: a solar project; imagining the unimaginable and anticipating the worse; the wake up of a dozed off fear; the most important accidents: the progress of the three main nuclear catastrophes, the human mistake of Three Mile Island, the days after the Chernobyl accident, in the dead cities around Fukushima; interview of Kenzaburo Oe (Japanese writer); the Blayais power plant to the test; 3 - The energy transition: is France capable to abandon nuclear energy?; Germany is going to re-launch gas

  17. Evaluation of the impact of technology transfers between public research laboratories and industrial companies. The case of the French nuclear authority

    Petit, Serge

    1999-12-01

    Public research institutions are increasingly expected to evaluate the economic impact of their research, but the generally available impact indicators are not satisfactory. This research develops indicators that grasp with greater detail the effects that are induced by R and D collaborations between a laboratory and a firm. Seven such indicators are being developed on the empirical evidence of twenty two R and D projects of the French Nuclear Authority (CEA). Functional relationships are being sought between these indicators and a couple of explanatory variables that stand for the profile of the innovating firm, the features of the collaboration and of the launched innovation. Kohonen's algorithm allows to extract robust associations between indicators and their determinants, thus founding a sort of 'mixed' methodology that relies on the principles of monograph observations and statistical data mining. Three kinds of results are derived from the empirical work: - the production of indicators that are complementary to the currently-used impact indicator, namely the innovation-induced turnover, and the definition of the scenarios in which they apply; - the evidence of a link between different ways of organising collaborative R and D projects and the underlying industrial objectives; - some guidelines for the construction of revenue-optimising contracts for the CEA. The results illustrate the immaterial dimension of technology and its importance in economic terms. The linear model, in spite of the criticism, is shown to produce interesting results in some cases.

  18. Nuclear safety in France after Fukushima - Critical analysis of complementary safety assessments (CSA) carried out on French nuclear installations after Fukushima

    International Nuclear Information System (INIS)

    Makhijani, Arjun; Marignac, Yves

    2012-02-01

    This report proposes a critical analysis of the approach carried out on the basis of the CSA (complementary safety assessment), from their specifications to the IRSN conclusions. It is notably based on the analysis performed by EDF on three nuclear sites (Gravelines, Civaux and Flamanville) which encompass the different levels of the nuclear power plants in France and the EPR project under construction, and on the analysis performed by Areva for La Hague reprocessing plants. Due to the short delay, only some sites and some problems have been considered. The CSA methodology is described. The EDF approach is discussed as well as the IRSN analysis of reports made by EDF, and then the different case studies. Beyond the conclusions of these reports, the authors highlight several major possible accidents which must be taken into account. They also outline that this CSA approach is a good starting point for the strengthening of nuclear safety

    In its first part, this report describes the (Japanese) Inquiry Commission's mandate, its expectations, what it did, what it did not do, and then describes the accident, gives a chronology of events after the earthquake and the tsunami occurred, and states and comments the following conclusions: a catastrophe with a human origin, earthquake-induced damages, an assessment of operational problems, problems met during emergency intervention, evacuation problems, unresolved public health and welfare problems, need to reform the regulators as well as the operator, laws and rules. Seven recommendations are proposed; they address the control of the nuclear regulation body, the reform of the crisis management system, the government responsibility for public health and welfare, the control of operators, criteria for a new regulator, a reform of laws related to nuclear energy, and the implementation of a system of independent inquiry commissions. Then the report comments and discusses in detail the results of the inquiry which first tried to assess whether the accident was avoidable, and studied various elements: the accident, the emergency response, the damage extent, the organisational problems in the prevention of the accident, the legal system. Results of inquiries on evacuated people and on personnel are given in appendix, as well as the content of all the Commission meetings

    Nuclear power plants (NPPs) release toxic emissions into the environment that may affect neighboring populations. This ecologic study was designed to investigate the possibility of an excess incidence of cancer in the vicinity of French NPPs by examining the incidence by municipality of 12 types of cancer in the population aged 15 years and older during the 1995-2011 period. Population exposure to pollution was estimated on the basis of distance from towns of residence to the NPP. Using regression models, we assessed the risk of cancer in a 20-km zone around NPPs and observed an excess incidence of bladder cancer (Relative Risk (RR), 95% Credibility Interval (95% CI)) in men and women (RR men  = 1.08; 95% CI: 1.00, 1.17 and RR women  = 1.19; 95% CI: 1.02, 1.39). Women living within the 20-km proximity areas had a significantly reduced risk of thyroid cancer (RR women  = 0.86; 95% CI: 0.77, 0.96). No excess risk of hematologic malignancies in either sex was seen. The higher than expected incidence of bladder cancer may be due to an excess incidence localized around the Flamanville NPP and the nearby La Hague nuclear waste treatment center, which is a source of chemical contaminants, many (including arsenic) of them known risk factors for bladder cancer. Differences in medical practices could explain the reduced risk of thyroid cancer. In this first study of adults living near NPPs in France, cancer incidence is significantly higher than in the references populations for one of the cancer types studied: bladder cancer. © 2017 UICC.

If policy problems are as important for civil nuclear than for military nuclear, it will be necessary to show concern about them because the Asian economy is in full development and Asia is not so frightened by nuclear power than Europe.

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

    1998-01-01

    The Electricite de France's N4 CHOOZ B nuclear power plant, two units of the world's largest PWR model (1450 Mwe each), has earned the Electric Power International's 1997 Powerplant Award. This lead NPP for EDF's N4 series has been improved notably in terms of civil works. The presentation will focus on the Reactor Building's inner containment wall which is one of the main civil structures on a technical and safety point of view. In order to take into account the necessary evolution of the concrete technical specification such as compressive strength low creep and shrinkage, the HSC/HPC has been used on the last N4 Civaux 2 NPP. As a result of the use of this type of professional concrete, the containment withstands an higher internal pressure related to severe accident and ensures higher level of leak-tightness, thus improving the overall safety of the NPP. On that occasion, a new type of prestressing has been tested locally through 55 C 15 S tendons using a new C 1500 FE Jack. These updated civil works techniques shall allow EDF to ensure a Reactor Containment lifespan for more than 50 years. The gains in terms of reliability and cost saving of these improved techniques will be developed hereafter

    Jones, C.

    2006-01-01

    Despite having the second best wind resources in Europe after the UK, the wind industry in France lags behind its European counterparts with just 6 W of installed wind capacity per person. The electricity market in France is dominated by the state-owned Electricite de France (EdF) and its nuclear power stations. However, smaller renewable generators are now in theory allowed access to the market and France has transposed the EU renewables directive into national law. The French governement has set a target of generating 10,000 MW of renewable capacity by 2010. The announcement of an increased feed-in tariff and the introduction of 'development zones' (ZDEs) which could allow fast-tracking of planning for wind projects are also expected to boost wind projects. But grid access and adminstrative burdens remain major barriers. In addition, French politicians and local authorities remain committed to nuclear, though encouraged by the European Commission, wind is beginning to gain acceptance; some 325 wind farms (representing 1557 MW of capacity) were approved between February 2004 and January 2005. France is now regarded by the international wind energy sector as a target market. One of France's leading independent wind developers and its only listed wind company, Theolia, is expected to be one of the major beneficiaries of the acceleration of activity in France, though other companies are keen to maximise the opportunities for wind. France currently has only one indigenous manufacturer of wind turbines, but foreign suppliers are winning orders

    The SON 68 inactive open-quotes R7T7close quotes composition is the French reference glass for the LWR nuclear waste glass. Vapor phase alteration was used to accelerate the reaction progress of glass corrosion and to develop the characteristic suite of secondary, alteration phases. Extensive solid-state characterization (AEM/SEM/HRTEM) was completed on six inactive R7T7 waste glasses which were altered in the presence of saturated water vapor (200 degrees C) for 91, 241, 908, 1000, 1013, and 1021 days. The AEM samples were examined in cross-section (lattice-fringe imaging, micro-diffraction, and quantitative thin-film EDS analysis). The glass monoliths were invariably covered with a thin altered rind. The layer became thicker with time: 0.5 μm for 22 days; 4 μm for 91 days; 6 μm for 241 days; 10 μm for 908 days; 26 μm for 1013 days; and 2 TeO 3 and (Ca,Sr)Mo 3 O 9 (OH) 2 , were found within the inner zones of surface layers, and they must have nucleated in situ, indicating that Ag, Te, Sr, and Mo can be retained within the surface layer. The majority of the surface layer volume is composed of two morphologically and chemically different structures: one consists of well-crystallized fibrous smectite aggregates occurring along with cavities, the A-domain; and the other consists of poorly-crystallized regions containing needle-like smectite (montmorillonite) crystallites, a silica-rich amorphous matrix, and possibly ZrO 2 particles, the B-domain

    The thermal stability of the French nuclear waste glass was investigated experimentally and by modeling to predict its long-term evolution at low temperature. The crystallization mechanisms were analyzed by studying devitrification in the supercooled liquid. Three main crystalline phases were characterized (CaMoO{sub 4}, CeCO{sub 2}, ZnCr{sub 2}O{sub 4}). Their crystallisation was TO 4.24 wt%, due to the low concentration of the constituent elements. The nucleation and growth curves showed that platinoid elements catalysed nucleation but did not affect growth, which was governed by volume diffusion. The criteria of classic nucleation theory were applied to determine the thermodynamic and diffusional activation energies. Viscosity measurements illustrate the analogy between the activation energy of viscous flow and diffusion, indicating control of crystallization by viscous flow phenomena. The combined action of nucleation and growth was assessed by TTT plots, revealing a crystallization equilibrium line that enables the crystallized fractions to be predicted over the long term. The authors show that hetero-genetics catalyze the transformation without modifying the maximum crystallized fraction. A kinetic model was developed to describe devitrification in the glass based on the nucleation and growth curves alone. The authors show that the low-temperature growth exhibits scale behavior (between time and temperature) similar to thermo-rheological simplicity. The analogy between the resulting activation energy and that of the viscosity was used to model growth on the basis of viscosity. After validation with a simplified (BaO{sub 2}SiO{sub 2}) glass, the model was applied to the containment glass. The result indicated that the glass remained completely vitreous after a cooling scenario with the one measured at the glass core. Under isothermal conditions, several million years would be required to reach the maximum theoretical crystallization fraction. (author)

    In this article, the author briefly recalls and comments the present context: an uncertain evolution of the world fossil fuel market, a grotesque European electricity market, an always more complex and constraining regulation of nuclear safety, and a still unclear French policy. Then, he proposes a critical overview of some popular beliefs on the priority given to energy savings, on nuclear energy (its role in the energy mix and in front of renewable energies, its impact on the financial situation of EDF, its related costs), on the issue of intermittency of renewable energies, and on the strengths and weaknesses of nuclear energy. He finally proposes some initiatives to provide the public with unbiased information

  15. Future of French refining

    1993-01-01

    Over recent years, the refining industry has had to grapple with a growing burden of environmental and safety regulations concerning not only its plants and other facilities, but also its end products. At the same time, it has had to bear the effects of the reduction of the special status that used to apply to petroleum, and the consequences of economic freedom, to which we should add, as specifically concerns the French market, the impact of energy policy and the pro-nuclear option. The result is a drop in heavy fuel oil from 36 million tonnes per year in 1973 to 6.3 million in 1992, and in home-heating fuel from 37 to 18 million per year. This fast-moving market is highly competitive. The French market in particular is wide open to imports, but the refining companies are still heavy exporters for those products with high added-value, like lubricants, jet fuel, and lead-free gasolines. The competition has led the refining companies to commit themselves to quality, and to publicize their efforts in this direction. This is why the long-term perspectives for petroleum fuels are still wide open. This is supported by the probable expectation that the goal of economic efficiency is likely to soften the effects of the energy policy, which penalizes petroleum products, in that they have now become competitive again. In the European context, with the challenge of environmental protection and the decline in heavy fuel outlets, French refining has to keep on improving the quality of its products and plants, which means major investments. The industry absolutely must return to a more normal level of profitability, in order to sustain this financial effort, and generate the prosperity of its high-performance plants and equipment. 1 fig., 5 tabs

    Decrees providing for the enforcement of the radiation protection laws allow establishments to provide the individual surveillance of the workers exposure to ionizing radiations. A decree is relative to the dismantling of the fuel fabrication plant at Pierrelatte. A decree allows the Cea to modify a laboratory on irradiated fuels at Saclay. A departmental order allows EDF to continue the taking of samples in water, liquid and gaseous effluents releases for the operating site of Paluel and Flamanville. Some decrees are relative to the radioactive material transport. A law about the evaluation of environmental impact in a transfrontier context has been passed ( 17 activities such nuclear power plants, reactors, facilities devoted to the production, enrichment of nuclear fuel, storage, and processing of spent fuels are listed). A decree allows the transfer of ORIS by cea-Industry, Cea subsidiary sold to the Schering group. (N.C.)

  17. French electricity results 2002

    International Nuclear Information System (INIS)

    2002-01-01

    RTE, the manager of the French power system, announces a high increase in electricity exports to the other countries of the European Union in 2002. In France, the year 2002 was marked by stable power consumption, but a noteworthy increase in generation due to the rise of exports. In 2002, the RTE network conveyed 512.3 billion kWh (TWh) versus 503.1 billion kWh (TWh) in 2001, an increase of 1.8%. Overall French exports made considerable strides forward from 72.9 TWh in 2001 to 80.6 TWh in 2002, i.e. 10.6% more than in 2001. On the other hand, overall French imports fell substantially, from 4.4 TWh in 2001 to 3.8 TWh in 2002, or a drop of about 14%. In all, the export balance came to 76.8 TWh in 2002, versus 68.5 TWh in 2001, i.e. a rise of 12%. On Sunday, 22 December 2002, the historical record of the capacity export balance with a value of 13,277 MW, up 2.2%, was bettered. The particularly mild weather conditions in 2002 led to a drop in heating-related consumption, evaluated at 7 billion kWh compared with the prior year. A slight upturn in industrial consumption was to be noted, from 92.7 TWh in 2001 to 93.2 TWh in 2002, i.e. a growth of 0.5%. Total French consumption thus rose in 2002 to 448.7 TWh. Total consumption, adjusted for climate contingencies, showed a rise of 1.6% in 2002. French power producers showed an increase of nearly 2% and the first wind farm was connected to the power transmission network. French electricity output came to 532.9 TWh in 2002, a growth of 1.9%. This increase is divided up between nuclear generation, up 4%, and conventional thermal generation, on the rise by 15.3%. The substantial share of thermal generation can be explained by a correlative drop in hydro generation (less 16.6% compared with 2001) mainly due to extremely low water availability observed during the first months of the year. With 415.5 TWh in output, nuclear power plants provided 78% of French generation, fossil-fired power plants 9.9% with an output of 52.9 TWh

  20. Epidemiological study of workers employed in the French nuclear fuel industry and analysis of the health effects of uranium compounds according to their solubility

    International Nuclear Information System (INIS)

    Zhivin, Sergey

    2015-01-01

    External γ-radiation exposure has been shown to be associated with mortality risk due to leukemia, solid cancer, and, possibly, circulatory diseases (CSD). By contrast, little information is available on health risks following the internal contamination, especially the inhalation of uranium compounds with respect to their physicochemical properties (PCP), such as solubility, isotopic composition and others. The aim of this PhD thesis was to estimate mortality risk of cancer and non-cancer diseases in French nuclear fuel cycle workers and comprises three objectives: (1) evaluation of the impact of uranium on mortality through a critical literature review, (2) analysis of cancer and non-cancer mortality in a cohort of uranium enrichment workers, (3) analysis of the relationship between CSD mortality and internal uranium dose in AREVA NC Pierrelatte workers. Existing epidemiological data on uranium PCP and associated health outcomes are scarce. Studies of nuclear fuel cycle workers by sub-groups within the specific stage of the cycle (e.g., uranium enrichment and fuel fabrication) are considered the most promising to shed light on the possible associations, given that such sub-groups present the advantage of a more homogenous uranium exposure. To study the mortality risk associated with exposure to rapidly soluble uranium compounds, we set up a cohort of 4,688 uranium enrichment workers with follow-up between 1968 and 2008. Individual annual exposure to uranium, external γ-radiation, and other non-radiological hazards (trichloroethylene, heat, and noise) were reconstructed from job-exposure matrixes (JEM) and dosimetry records. Over the follow-up period, 131,161 person-years at risk were accrued and 21% of the subjects had die. Analysis of Standardized Mortality Ratios (SMR) showed a strong healthy worker effect (SMR all deaths 0.69, 95% confidence intervals (CI) 0.65 to 0.74; n=1,010). Exposures to uranium and external γ-radiation were not significantly associated

    International Nuclear Information System (INIS)

    2009-11-01

    This report first presents India as a new actor in international nuclear cooperation, describing the evolution of India's status with respect to non proliferation rules: India is not a NPT (Nuclear non-Proliferation Treaty) member but nuclear cooperation has been recently made possible with the agreement of the NSG (Nuclear Suppliers' Group). The author notes that several cooperation agreements have already been signed with different countries (Russia, United States, Argentina, Kazakhstan, Mongolia, and Namibia). Then, the author gives assessments of Indian energy production and need, briefly presents the Indian nuclear energy program, and the cooperation perspectives for the French companies. In a second part, the author comments the cooperation agreement content, and more particularly the guarantees awarded to India, the dispositions aimed at the struggle against nuclear proliferation. Considering all these issues, the author supports the ratification of the agreement by the French Parliament

    An agreement between France and Russia was signed on June 20, 2000 about the civil liability of Russia because of the supply of French material devoted to Russian nuclear facilities. This agreement was necessary because Russia do not belong to any of the two big international civil liability systems relative to nuclear energy, i.e. the Paris convention from July 29, 1960 (in the OECD framework) and the Vienna convention from May 21, 1963 (in the IAEA framework). This agreement offers a protection to the French nuclear suppliers against any damage claims in the case of a nuclear accident occurring on the Russian federation territory. This project of law aims at approving this agreement. (J.S.)

    2006-01-01

    This barometer presents the opinion of a representative of 2013 french people, about three main themes: the nuclear, the attitude facing the fuel prices increase and the electric power from renewable energies. For a short majority of French, the nuclear electric power offers for the most part advantages (problems of accidents and radioactive wastes management, but no greenhouse effect impact and economical advantages). Most of French modified their attitude following the fuels prices increase and place the fuel consumption as a major criteria for a new vehicle purchase. The French are in majority favour of the renewable energies. (A.L.B.)

    The protection of the aquatic and terrestrial environment from a wide range of radioactive contaminants released by nuclear industry requires continuous monitoring of radionuclides released into the environment. Specific measurement methods depending of the radionuclide are used to determinate this contribution. A lot of radionuclide can easily be measured at low level by gamma spectrometry, like {sup 137}Cs, {sup 60}Co..., but others like {sup 90}Sr, {sup 63}Ni or {sup 55}Fe require prior specific radiochemical separations. Activity of {sup 90}Sr values in environmental samples are available but only few measurements of {sup 63}Ni and {sup 55}Fe activities have been carried out in samples collected in the environment close to French nuclear power plants located on the Loire and Garonne rivers despite they represent 12% to 24% for {sup 63}Ni activity and <1% for {sup 55}Fe + other minor radionuclides of total activity of their liquid effluent discharges. {sup 90}Sr is not rejected by the liquid effluent discharges of Nuclear Power Plants and can be found in the environmental samples because of thermonuclear test and subsequently after the Chernobyl nuclear power plant accident. Considering the French Nuclear Power Plant located on Loire and Garonne rivers, the determination of {sup 90}Sr, {sup 63}Ni and {sup 55}Fe levels in the environmental samples around French nuclear power plants is carried out to detect the traces of these radionuclides originating from nuclear technology activities. The environment around five French nuclear Power Plants was investigated for 4 years between 2009 and 2014. The radionuclide activities determined by liquid scintillation counting after chemical steps were performed on a large set of various matrix samples likely to be encountered in environmental monitoring as soils, sediments, terrestrial and aquatic bio-indicators. It was found that the mean activity concentration of the most frequently detected was for the radionuclide {sup 90

    2014-01-01

    About 80 fire starts are reported in EDF nuclear power plants every year but only 3 or 4 turn into a real fire and none has, so far, has led to a major safety failure of a nuclear plant. A new regulation has been implemented in july 2014 that strengthens the concept of defense in depth, proposes an approach that is proportionate to the stakes and risks, this proportionality means that the requirements for a power reactor are not the same as for a nuclear laboratory, and imposes an obligation or result rather than of means. The second article deals with the fire that broke out in the waste silo number 130 at La Hague plant in january 1981. The investigation showed that the flammability of the silo content had been underestimated. The third article presents the consequences of the fire that broke out in a power transformer at the Cattenom plant in june 2013. The fire was rapidly brought under control thanks to the immediate triggering of the emergency plan. The article details also the feedback experience of this event. (A.C.)

  19. Microbial activity in argillite waste storage cells for the deep geological disposal of French bituminous medium activity long lived nuclear waste: Impact on redox reaction kinetics and potential

    Science.gov (United States)

    Albrecht, A.; Leone, L.; Charlet, L.

    2009-04-01

    Micro-organisms are ubiquitous and display remarkable capabilities to adapt and survive in the most extreme environmental conditions. It has been recognized that microorganisms can survive in nuclear waste disposal facilities if the required major (P, N, K) and trace elements, a carbon and energy source as well as water are present. The space constraint is of particular interest as it has been shown that bacteria do not prosper in compacted clay. An evaluation of the different types of French medium and high level waste, in a clay-rich host rock storage environment at a depth between 500 and 600 m, has shown that the bituminous waste is the most likely candidate to accommodate significant microbial activity. The waste consists of a mixture of bitumen (source of bio-available organic matter and H2 as a consequence of its degradation and radiolysis) and nitrates and sulphates kept in a stainless steel container. The assumption, that microbes only have an impact on reaction kinetics needs to be reassessed in the case where nitrates and sulphates are present since both are known not to react at low temperatures without bacterial catalysis. The additional impact of both oxy-anions and their reduced species on redox conditions, radionuclide speciation and mobility gives this evaluation their particular relevance. Storage architecture proposes four primary waste containers positioned into armoured cement over packs and placed with others into the waste storage cell itself composed of a cement mantle enforcing the argillite host rock, the latter being characterized by an excavation damaged zone constricted both in space and in time and a pristine part of 60 m thickness. Bacterial activity within the waste and within the pristine argillite is disregarded because of the low water activity (biofilms are within the interface zones. A major restriction for the initial development of microbial colonies is the high pH controlled by the cement solution. Archea are able to survive

  20. Border installations

    International Nuclear Information System (INIS)

    Lenaerts, Koen

    1988-01-01

    Border installations cover all nuclear plants located near the border with a neighbouring state. However, the actual distance depends on the context. The distance can vary considerably. Also the prohibition on siting near a heavily populated area also defines the actual distance variably. The distance criteria may be modified by other factors of topography, prevailing climate and so on. Various examples which illustrate the problems are given. For example, the Creys-Melville nuclear power plant is 80km from Geneva and the Cattonam installation is 12km from the French border with Luxembourg and Germany. The Cattenom case is explained and the legal position within the European Institutions is discussed. The French licensing procedures for nuclear power stations are described with special reference to the Cattenom power plant. Border installations are discussed in the context of European Community Law and Public International Law. (U.K.)

    International Nuclear Information System (INIS)

    Chesnais, L.

    2006-01-01

    An opinion poll made in France in 2006 shows that: - French people backs nuclear energy with a slight margin (45% versus 42%), - French people agrees with the electricity production policy led by the government, - about 4 people out of 10 expect a sharp increase in prices concerning car fuels, natural gas and heating fuels in a near future, on the other hand fewer people than in previous years are expecting a price rise for electricity. In this article some figures concerning the consumption of energy in France are given: - 230.000 jobs are directly or indirectly involved in the energy sector, this sector represents 5% of all investment, - a total bill of 24 milliard euros for the energy imports, and - energy spending represents 7.6% of the household budget.

  8. PWR standardization: The French experience

    International Nuclear Information System (INIS)

    Bacher, P.E.

    1987-01-01

    After a short historical review of the French PWR programme with 45000 MWe in operation and 15000 MWe under construction, the paper first develops the objectives and limits of the standardizatoin policy. Implementation of standardization is described through successive reactor series and feedback of experience, together with its impact on safety and on codes and standards. Present benefits of standardization range from low engineering costs to low backfitting costs, via higher quality, reduction in construction times and start-up schedules and improved training of operators. The future of the French programme into the 1990's is again with an advanced standardized series, the N4-1400 MW plant. There is no doubt that the very positive experience with standardization is relevant to any country trying to achieve self-reliance in the nuclear power field. (author)

    2012-02-09

    With 58 reactors in operation, France is at 75% a nuclear-dependent country for power generation. For forty years no calling into question of this policy has been possible. The Fukushima catastrophe of March 11, 2011 has changed the deal. Several countries, like Germany, Switzerland, Belgium and Italy have taken the decision to get out of nuclear energy. In France, the taboo question of its abandonment has moved to the front of the scene. Some political parties have proposed a significant reduction of the nuclear share in the energy mix while some 'zero nuclear' scenarios are already on the table. (J.S.)

    As IRSN is considered as a reference laboratory for radioactivity measurements, French health ministry and French nuclear safety authority asked IRSN to carry out a study in order to get a fresh and complete status of radiological water quality of French bottled waters. The study was carried out during 12 months in 2012. A total of 142 bottled waters samples were analyzed (75 spring waters and 67 natural mineral waters). The laboratories of IRSN were in charge of: - systematic measurement of radioactivity following requirements of the French health ministry (Circulaire du 13/06/2007) regarding the monitoring and management of sanitary risk linked to the presence of radionuclides in drinking waters (natural mineral waters excepted). - systematic uranium mass concentration determination; - a few radon-222 gas measurements for waters in glass bottles. This study is a flash assessment of radiological characteristics of French bottled waters, at the analysis date for the sample received. It was done in informative way and was not done for regulatory control purposes.. This study has shown that: - all bottled waters analyzed have a tritium activity concentration lower than the quality reference value of 100 Bq/l of the French regulation; - More than 105 bottled waters analyzed (80% of the springs waters and 70% of natural mineral waters received) have a gross alpha activity concentration lower than the guideline value of 0,1 Bq/l of the French regulation; - All bottled waters analyzed have a residual gross beta activity concentration lower than the guideline value of 1 Bq/l of the French regulation; - All bottled waters analyzed have a uranium mass concentration lower than the provisory guideline value of 30 μg/l of the WHO for drinking waters; - radon-222 was only significantly measured once upon 6 glass bottled waters with a value far below the reference value of 100 Bq/l of the future European Directive on drinking waters.

    'Today, some 75 % of France's electricity is generated by nuclear plants'. This was the theme of the advertising campaign launched for the second time in May 1992 by Electricite de France in national daily newspapers and magazines, in regional publications, on cinema and on TV. Compared to 1991 the second campaign was a new step in communication: first, was the wish to inform better the public. A Minitel program '3614 EDF' was created and connected by general public including a lot of information about nuclear energy and the way to visit a nuclear plant; secondly, was the use of TV media to target a larger population. The TV spot, 'the nuclear drill', uses humor to get more impact on the public. The campaign received an encouraging reception from the press, which admired its boldness and originality. As far as the general public is concerned, the campaign achieved its goals, as illustrated by the results of post-campaign surveys carried out to measure its effect. The segment of population targeted by campaign was mainly the so called 'pragmatics'. 'Pragmatics', who account for 25 % of the French population, are young, have a good education and are well informed. This category was selected as it shows a subtle attitude towards nuclear power, with more doubts than certainties. Moreover, this segment of the population has proven to be open to information issued by EDF and also plays a key role in influencing social trends. 63% of the segment targeted by the campaign (pragmatics) and 56% of the whole french population saw the ads

    2005-01-01

    In Phebus (French in pile facility; PWR scale 1/5000) experiments, performed by the Institut de Radioprotection et de Surete Nucleaire, few quantities of organic iodides were registered after interaction between iodine and reactor containment paint. This study concerns all mechanisms of chemical reactions between iodine and the polymer of the paint in order to estimate the organic iodides released from the paint. At first, all the paint components had been identified. Several models of chemical sites of the polymer were synthesized and tested with iodine in different conditions of temperature and radiation. These experiments showed interactions between iodine and secondary or tertiary amines by charge transfer. In few cases, the complex of tertiary amines creates oxidation reactions. (author)

    Forty years after the first bomb in Moruroa, a conference to promote recognition and justice for all victims of nuclear tests. More than thirty speakers, scientists, legal experts, parliamentarians and members of associations from French Polynesia, Australia, Fiji, New Zealand, the United States, Japan, the Netherlands and France debated on June 29-30, at the President's palace in Papeete, on the rights of the victims of nuclear tests to be recognized by nuclear powers. During this conference, we heard scientists explain very clearly that contamination and irradiation had widespread consequences including on the gene pool of the victims. Today, damage found on the chromosomes of Polynesian thyroid cancer patients who lived 1000 km away from Moruroa is ten times higher than damage found on average nuclear workers. Researchers tell us that many of those who worked on nuclear sites die earlier. Average life expectancy for the veterans from New Zealand is for example 51 years - and for most of them a life marred by suffering and cancers. Researchers tell us that conducting credible surveys is becoming more and more difficult as the impact of radiations that were absorbed 20, 30 or even 40 years earlier is getting more difficult to discern from damages due to old age or other illnesses. Testimonies and information given at this conference are indispensable for the public to realize the actual impact of the nuclear tests as well as show the elected representatives how urgent it is to meet the expectations of the victims. The suffering and strong discontent of the former test site workers moved the parliamentarians as well as the public. The strong words that were said will have to give a human face to the law we will have to implement in order to do justice to the victims. An impact of nuclear testing on health and environment are experienced by many peoples in the world. The testing nations are of course the ones who should compensate the victims. But there is also a

    2013-01-01

    The aim of this publication is to provide a practical tool for emergency planning for States embarking on a nuclear power programme and to fulfil, in part, functions assigned to the IAEA in the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency ('Assistance Convention'). Under Article 5.a (ii) of the Assistance Convention, one function of the IAEA is to collect and disseminate to State Parties and Member States information concerning methodologies, techniques and available results of research relating to such emergencies. As established in the publication Preparedness and Response for a Nuclear or Radiological Emergency (IAEA Safety Standards Series No. GS-R-2), the practical goal of emergency response is 'to ensure that arrangements are in place for a timely, managed, controlled, coordinated and effective response at the scene, and at the local, regional, national and international level, to any nuclear or radiological emergency'. In 2011 the IAEA General Conference, in resolution GC(55)/RES/9, encouraged States 'embarking on new nuclear power programmes to take timely and proactive steps, based upon gradual and systematic application of IAEA safety standards, to establish and sustain a strong safety culture'. It also 'emphasizes the importance for all Member States to implement emergency preparedness and response mechanisms and develop mitigation measures at a national level, consistent with the IAEA's Safety Standards, for improving emergency preparedness and response, facilitating communication in an emergency and contributing to harmonization of national criteria for protective and other actions'. This publication, issued in the IAEA Emergency Preparedness and Response Series, is intended to assist on steps to be taken by States embarking on a nuclear power programme to establish effective national capabilities and arrangements of preparedness for and response to a nuclear or radiological emergency (hereinafter referred to as

    Electricite de France (EDF), the french national electricity company, is operating 54 standardized pressurizer water reactors. This about 500 reactor-years experience in nuclear stations operation and maintenance area has allowed EDF to develop its own strategy for monitoring of age-related degradations of NPP systems and components relevant for plant safety and reliability. After more than fifteen years of experience in regulatory transient data collection and seven years of successful fatigue monitoring prototypes experimentation, EDF decided to design a new system called SYSFAC (acronym for SYsteme de Surveillance en FAtigue de la Chaudiere) devoted to transient logging and thermal fatigue monitoring of the reactor coolant pressure boundary. The system is fully automatic and directly connected to the on-site data acquisition network without any complementary instrumentation. A functional transient detection module and a mechanical transient detection module are in charge of the general transient data collection. A fatigue monitoring module is aimed towards a precise surveillance of five specific zones particularly sensible to thermal fatigue. After the first step of preliminary studies, the industrial phase of the SYSFAC project is currently going on, with hardware and software tests and implementation. The first SYSFAC system will be delivered to the pilot power plant by the beginning of 1996. The extension to all EDF`s nuclear 900 MW is planned after one more year of feedback experience.

    Chlorine 36 is one of the main radionuclides of concern for French graphite waste disposal. In order to help the understanding of its leaching behaviour under disposal conditions, the respective impact of temperature, irradiation and gas radiolysis on chlorine release in reactor has been studied. Chlorine 36 has been simulated through chlorine 37 ion implantation in virgin nuclear graphite samples. Results show that part of chlorine is highly mobile in graphite in the range of French reactors operating temperatures in relation with graphite structural recovering. Ballistic damage generated by irradiation also promotes chlorine release whereas no clear impact of the coolant gas radiolysis was observed in the absence of graphite radiolytic corrosion. (author)

    Background We conducted a mortality study on a cohort of French nuclear workers employed at Electricite de France (EDF). A first cancer mortality analysis had covered the period 1968-1994. This paper presents results from a mortality analysis including nine additional years of follow-up to cover workers employed from 1968 to 2003. Methods The cohort includes 22 393 workers, 97% of whom are males. Employment data were updated using the EDF personnel file. Vital status was ascertained using the French National Registry of Population, and further completed using EDF personnel and pension files. Causes of death were obtained from the National registry of causes of death. Standardised Mortality Ratios (S.M.R.) were computed using national rates as references. Variations of all causes and all cancers S.M.R.s were studied according to demographic and occupational characteristics. Results At the study end point (31/12/2003), 74% of workers are still in active employment. Only 0.3% of workers are lost to follow-up. The median duration of follow-up is 20 years. Causes are ascertained for 96% of deaths. The total number of deaths is 874, 307 of which are cancer deaths. S.M.R.s for all causes and cancers show a significant deficit compared to the French national mortality. No significant excess was observed for any of the cancer sites studied. Non-significant excesses are observed for pancreatic, pleural, kidney and brain cancer. Significant variations of all causes S.M.R.s according to age at study entry and attained age are observed. Significant variations of all causes and all cancers S.M.R.s according to diploma at employment are observed, with a reduced S.M.R. for a higher level of diploma. Conclusion There is a significant deficit of mortality compared to the general population, reflecting a strong Healthy Worker Effect. Although nine years of follow-up were added, this cohort is made up of young workers, most of whom are still in active service. Regular updating of the

    After gaining control of radioactive material transport in June 1997, the French Nuclear Safety Authority (ASN) decided to apply the International Nuclear Event Scale (INES scale) to transport events. The Directorate General for Nuclear Safety and Radioprotection (DGSNR) requests that radioactive material package consignors declare any event occurring during transport, and has introduced the use of the INES scale adapted to classify transport events in order to inform the public and to have feedback. The INES scale is applicable to events arising in nuclear installations associated with the civil nuclear industry and events occurring during the transport of radioactive materials to and from them. The INES scale consists of seven levels. It is based on the successive application of three types of criterion (off-site impact, on-site impact and degradation of defence in depth) and uses the maximum level to determine the rating of an accident. As the transport in question takes place on public thoroughfares, only the off-site impact criteria and degradation of defence in-depth criteria apply. This paper deals with DGSNR's feedback during the past 7 years concerning the French application of the INES scale. Significant events that occurred during transport are presented. The French experience was used by the International Atomic Energy Agency (IAEA) to develop a draft guide in 2002 and the IAEA asked countries to use a new draft for a trial period in July 2004.
