    Electricite de France (EDF) makes increasing use of valve inspection systems to guarantee safety in its pressurized water reactor plants, improve plant availability and facilitate condition-based maintenance. A portable system known as SAMIR has been developed for inspection of motor-operated valves, and is now used on EDF`s 900-MW sites. For its 1300-MW units, EDF has chosen a more complete system which enables measuring thrust on the valve stem during a maneuver, using a sensor mounted on the yoke. To detect internal vale leaks, an on-site assessment has demonstrated the economic benefits of acoustic emission techniques. EDF has equipped its sites with analog leak detection systems which may soon be replaced by a digital model now being developed. (authors).

    The scope of French nuclear power led Electricite de France (EDF) to design standard products, manufactured in series but adaptable to different sites. Standardization is based on the decision on a single technology: pressurized water reactors (PWR). Thirty-four 900 MW and seventeen 1300 MW units are in operation on seventeen sites. The specific nature of French organization for normal operation and accident management results from equipment standardization and single licensee. This specificity is based on emergency plan standardization and highly structured national organization. Figs

    EDF's sales in the first quarter of 2014 were euro 21.2 billion, down 3.9% from the first quarter of 2013. At constant scope and exchange rates, sales were down 4.2% due to mild weather conditions, which impacted sales of electricity in France, gas sales abroad and trading activities in Europe. UK sales were nonetheless sustained by B2B sales due to higher realised wholesale market prices. In Italy, sales growth was driven by an increase in electricity volumes sold. The first quarter of 2014 also saw the strengthening of the Group's financial structure with the second phase of its multi-annual hybrid funding programme (nearly euro 4 billion equivalent) as well as the issue of two 100-year bonds in dollars and sterling aimed at significantly lengthening average debt maturity. 2014 outlook and 2014-2018 vision: - EDF Group has confirmed its financial objectives for 2014; - Group EBITDA excluding Edison: organic growth of at least 3%; - Edison EBITDA: recurring EBITDA target of euro 1 billion and at least euro 600 million in 2014 before effects of gas contract re-negotiations; - Net financial debt / EBITDA: between 2x and 2.5x; - Pay-out ratio of net income excluding non-recurring items post-hybrid: 55% to 65%. The Group has reaffirmed its goal of achieving positive cash flow after dividends, excluding Linky, in 2018

  10. Addressing Hydrogen Risks During Severe Accidents - EDF Approach

    International Nuclear Information System (INIS)

    Guieu, Serge

    2001-01-01

    Hydrogen mitigation systems for French PWRs have not been designed to cope with hydrogen release rates and quantities equivalent to those contemplated if some Severe Accident sequences were to occur. Prior to making any decision on the need for addressing this issue, EDF has looked at available alternatives, decided which one could be a reasonable candidate if further studies showed that the problem had to be addressed, and started R and D programmes aiming at the validation of the preferred candidate. This paper describes the process followed to evaluate the need for enhancing the capability of hydrogen mitigation measures, indicates which candidates were initially considered for mitigating the hydrogen risk and gives the rationales for selecting Passive Auto-catalytic Recombiners (PARS) as the preferred alternative. The PAR validation process is described and the main results confirming their capability are commented. Finally, insights on future on-site implementation are given. As a general conclusion, all the EDF 'efficiency tests programmes' described, in addition with results of other similar tests programmes performed in other countries (in particular: Germany and Canada) do not challenge the capability of PARS to operate in severe accidents representative conditions. Concerning the risk for a PAR to initiate a deflagration, EDF tests have shown that this risk is depending both on hydrogen and steam contents. The risk is more accurate when steam content is low. Roughly speaking, the hydrogen content limit, in presence of steam, to avoid this phenomenon is in the range of 8 vol %. In addition it has to be noted that this 'deflagration problem', does not challenge the interest to install PARS because: - in the containment of present NPPs, numerous ignition sources are still present, - in case of initiation of a deflagration by a PAR, it is likely that this deflagration will appear with an hydrogen amount in the containment much lower than without PARs

    The french nuclear programme has been widely publicized. In 1985, the total nuclear electricity generated was around 216 GWh, i. e. 70% of the electricity produced by electricity de France (EDF). If we consider only pressurized water reactors, at the end of 1985, 37 units were in operation (32 900 MWe and 5 1300 MWe) and 18 were under construction. I intend to review our experience with the safety of PWR's, but I will first present briefly some aspects related to the safety organization in France and the standardization policy. (author) [pt

    1997-01-01

    Electricite de France (EDF) makes increasing use of valve inspection systems to guarantee safety in its pressurized water reactor plants, improve plant availability and facilitate condition-based maintenance. A portable system known as SAMIR has been developed for inspection of motor-operated valves, and is now used on EDF's 900-MW sites. For its 1300-MW units, EDF has chosen a more complete system which enables measuring thrust on the valve stem during a maneuver, using a sensor mounted on the yoke. To detect internal vale leaks, an on-site assessment has demonstrated the economic benefits of acoustic emission techniques. EDF has equipped its sites with analog leak detection systems which may soon be replaced by a digital model now being developed. (authors)

    Ion exchange resins are widely used across EDF, especially within the nuclear division for the purification of water. Important applications include primary circuit, secondary circuit and effluent treatment, which require high quality nuclear grade resins to retain the dissolved species, some of which may be radioactive. There is a need for more and more efficient purification in order to decrease worker dose during maintenance but also to decrease volumes of radioactive resin waste. Resin performance is subject to several forms of degradation, including physical, chemical, thermal and radioactive, therefore appropriate resin properties have to be selected to reduce such effects. Work has been done with research institutes, manufacturers and on EDF sites to select these properties, create specifications and to continuously improve on these specifications. An interesting example of research regarding resin performance is the resin degradation under irradiation. Resins used in the CVCS circuit of EDF nuclear power plants are subject to irradiation over their lifetime. A study was carried out on the effects of total integrated doses of 0.1, 1 and 10 MGy on typically used EDF mixed bed resins in a 'mini-CVCS' apparatus to simultaneously test actual primary circuit fluid. The tests confirmed that the resins still perform efficiently after a typical CVCS radiation dose. Certain resins also need additional specifications in order to maintain the integrity of the particular circuits they are used in. Recently, EDF has updated its requirements on these high purity nuclear grade resins, produced generic doctrines for all products and materials used on site which include resins of all grades, and as a result have also updated a guide on recommended resin usage for the French fleet of reactors. An overview of the evolutions will be presented. (authors)

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

  1. MOX use in PWRs. EDF operation experience

    International Nuclear Information System (INIS)

    Provost, Jean-Luc; Debes, Michel

    2011-01-01

    From the origin, EDF back-end fuel cycle strategy has focused on 'closing the fuel cycle', in other words integrating fuel reprocessing, with vitrification of high level waste concentrated within small volumes, and the recycling of valuable materials. The implementation of this policy was marked in 1987 by the first loading of sixteen MOX. By December 2010, 20 reactors have been loaded with 1750 tHM of MOX. EDF current strategy is to match the reprocessing program with MOX manufacturing capacity to limit the quantity of separated plutonium. This is routinely called the 'flow ad-equation' strategy. Currently, the MOX Parity core management achieves balance of MOX and UOX performance with a significant increase of the MOX discharge burn-up. Globally, the behavior under irradiation of MOX fuel assemblies has been satisfactory. So far, from the beginning of MOX use in EDF PWRs, only 6 MOX FAs with rod leakage have been identified, which gives a very satisfactory level of reliability. The industrial maturity of MOX fuel, with increased performances, allows the improvement of nuclear KWh competitiveness and of the plant operation performance, while maintaining in operation the same safety level, without significant impact on environment and radiological protection.

  13. Civil engineering: EDF needs for concrete modelling

    1997-01-01

    Concrete structures which are encountered at EDF, like all civil engineering structures, age. In order to adapt the maintenance conditions of these structures, particularly to extend their service life, and also to prepare constructions of future structures, tools for predicting the behaviour of these structures in their environment should be available. For EDF the technical risks are high and consequently very appropriate R and D actions are required. In this context the Direction des Etudes et Recherches (DER) has developed a methodology for analysing concrete structure behaviour modelling. This approach has several aims: - making a distinction between the problems which refer to the existing models and those which require R and D; - displaying disciplinary links between different problems encountered on EDF structures (non-linear mechanical, chemical - hydraulic - mechanical coupling, etc); - listing of the existing tools and positioning the DER 'Aster' finite element code among them. This document is a state of the art of scientific knowledge intended to shed light on the fields in which one should be involved when there is, on one part a strong requirement on the side of structure operators, and on the other one, the present tools do not allow this requirement to be satisfactorily met. The analysis has been done on 12 scientific subjects: 1) Hydration of concrete at early ages: exothermicity, hardening, autogenous shrinkage; 2) Drying and drying shrinkage; 3) Alkali-silica reaction and bulky stage formation; 4) Long term deterioration by leaching; 5) Ionic diffusion and associated attacks: the chlorides case; 6) Permeability / tightness of concrete; 7) Concretes -nonlinear behaviour and cracking (I): contribution of the plasticity models; 8) Concretes - nonlinear behaviour and cracking (II): contribution of the damage models; 9) Concretes - nonlinear behaviour and cracking (III): the contribution of the probabilistic analysis model; 10) Delayed behaviour of

    Electricite de France, the French electric utility, has to face a formidable mutation. The deregulation of the power market will lead to a social, commercial, judicial, financial and international 'big-bang'. The company has been weakened by disappointing results and by an embarrassing running into debts. This dossier analyzes the consequences of the deregulation of the French power market on the future evolution of EdF. It includes the analysis made by a French economist, E. Cohen, an interview and a portrait of F. Roussely, head of EdF, a presentation of Easenergy, a start-up of EdF which makes partnerships with US energy-related companies, the worries of EdF's employees and the redistribution of the syndicates power inside the company, the controversy around EdF's 2002 results and the points that remained in the shade, EdF's European competitors and the progressive opening of the French power market, EDF's production tool and its availability (58 nuclear reactors, 538 hydroelectric power plants and 26 thermal power plants), the costly foreign markets strategy of EdF and the under-capitalization of the company.

  19. Assessment of public safety around EDF facilities

    Energy Technology Data Exchange (ETDEWEB)

    Poupart, M. [Electricite de France, Paris (France)

    2004-09-01

    Electricite de France (EDF) recognizes that a dam's structural resistance and its capacity to withstand heavy flooding are 2 of the most significant safety aspects for hydroelectric power stations. However, in addition to dam failure, there are safety risks for the public who frequent the rivers up and down stream from the dam, as well as on property and the environment. A fatal accident which occurred in 1995 down river from EDF's Monteynard hydroelectric facility on the Drac River prompted the utility to take measures to improve control over this type of hazard. Collaboration with public authorities led to an action plan to educate the public about possible danger areas and to improve methods of reducing risks. Regulations regarding access to these areas were also studied along with ways of informing and warning the public. All the stretches of river directly above and below the power stations and dams were listed systematically and a qualitative analysis was carried out of any possible dangers. This led to changes in operating rules, technical instructions and power plant operating regulations. Certain areas are designated as prohibited areas, such as places subject to hazards caused by violent and unexpected water discharges. This paper outlined the Hydraulic Safety Significant Event (HSSE) classification which relates to an operational event related to water that is liable to affect human beings, the environment, water level or flow rate. 9 figs.

    1999-01-01

    First, what are, for EDF, the main issues dealing with the future management of low level wastes (LLW) will be recalled; and followed by a description of what are the implications of implementing these management principles: areas zoning, set up of pathways, traceability of the wastes and associated controls. The origin of the wastes will then be described using both qualitative and quantitative approaches; the description will specifically address the spreading of wastes production in time. LLW management at EDF will then be envisaged: storage in a specific discharge, pathways for treatment and elimination of wastes with acceptable radiological impact and costs. The example of LLW oils will be developed: particularly as far as hypothesis and results concerning the radiological impacts are concerned. The choice of incineration will then be justified, however expected difficulties to implement it industrially will be pointed out. Other on going studies and their main results will be mentioned: the present time is a turning point on that issue between thought and action; to be on going dismantling must take into account the emerging principles and give rise to good communication.

    2018-01-01

    Electricite de France (EDF), the state-owned and main power producer in France is, as the Titanic liner, lacking agility to navigate into the wild seas of the French energy transition policy. Besides, the era of engineers that construct energy cathedrals and of nuclear full supremacy is now well over, giving the way to innovative management policies with workers participation and digitalisation. EDF is preparing a new strategy addressing market opening and deregulation, renewable energy sources, and more freedom for EDF's numerous subsidiary companies. A second paper precisely concerns Dalkia, one of EDF's subsidiaries which is specialized in energy efficiency, heat and cold generation and networks that are more and more supplied by renewable energies. A third paper addresses EDF-SEI, whose specialty is energy autonomy in isolated areas (islands, etc.)

    1999-11-08

    In the last years Electricite de France (EDF) and Gaz de France (GDF) developed intervening strategies in a number of sectors opened to competition, the so-called strategies of diversification or complementary activities. These new strategies have multiple objectives as, for instance, prospective monopole evolution, increasing exigence of the consumers' demand, or else competence valuing. Ever since 1991, these strategic orientations developed with the support of public powers that worked out first measures of organization and monitoring. Although the frame was loose and rather tolerant, boosting EDF and GDF diversification was perceived by the concerned professionals as an aggression directed against them. Following a strong mobilization of professional organizations and a number of elected persons, in mid 1993, the minister of industry was impelled to tackle personally with the matter what resulted in an accurate system of framing. The GDF diversification is essentially characterized by a 'thermal pole' corresponding to the activities of heating operation. GDF controls, around the company Danto Rogeat and the old branches of Shell group, about 5% of a market of heating operation in France, i.e., represents the third place in a rather monopolized sector where the two main operators represent almost 75%. The EDF diversification is but more diffuse. Three main fields emerge distinctly: the waste processing, public lighting, and engineering. EDF is also present on more restraint markets as cartography, tele-surveillance, cable TV, aquaculture. The implementation of the system is presented where prerogatives of the Council of State on one hand and the Council of Competition on the other hand are stipulated. The disposition frame system is constituted of two measures stipulating the application of commendation from the two councils and provisions ensuring the transparency, respectively.

    Since 1968 'EDF Archives' has been in charge of collecting and preserving EDF's documents. EDF distinguishes 2 types of documents: documents (including data) that are still used by EDF teams in their daily work for knowledge transmission or legal aspects and earlier materials that are used for research works in history, sociology or economics. EDF being a public limited liability company (SA) with a public service mission, its archives are both private and public. The oldest documents date back in the 19. century as a legacy of the 2400 enterprises producing or transporting or dispatching electricity or gas that were nationalized in 1946 to form the EDF company. EDF's archives represent 100 linear kilometers of documents, 8 kilometers of which can be consulted by the public. In 2015 a club of the archivists from the nuclear industry was created, its aims were to manage common archives, to build a mapping of all corporate archives and to harmonize managing rules. (A.C.)

    1992-09-01

    At Electricite de France (EDF), since 1978, the operating instruments which ensure the DETECTION function, have been completed on turbogenerators by a specialized ''off-line'' vibration monitoring system, which allows a posteriori DIAGNOSIS analysis. However because of a need of a real time and more elaborated DETECTION function, the concept of the Monitoring and Diagnosis Aid Station (Poste de Surveillance et d'Aide au Diagnostic: PSAD) has been developed. It federates the processing of monitoring, organized into several functions, and includes the monitoring of turbogenerators (TGS) and reactor coolant pumps (RCP). The purpose of this paper is to present, on the one hand, the monitoring functions of TGS and RCP and on the other, the first experimental results on the behaviour of three RCP, obtained through a SAMT (Surveillance Automatisee des Machines Tournantes - Automatic monitoring of rotating machines) prototype.

    The public utility contract as foreseen by article 1 of the law from August 9, 2004 was signed on October 24, 2005. It represents the reference of EDF's (Electricite de France) commitments for its different activities of power producer-supplier and network manager. It precises also the commitments of the manager of the public energy transportation system (RTE EDF-Transport). It describes the level of commitment of EDF group over the 2005-2006-2007 era and precises the financial compensation modalities of its public utility missions and of its commitments as described in the contract. The public utility plan indicates the level of investments planned by EDF in the domain of power generation and networks. This document gathers: the talk given by D. de Villepin, Prime Minister, during the signature of the contract, the talk and presentation (slides) given by P. Gadonneix, head of EDF, the public utility contract between the government and EDF, and the public utility plan. (J.S.)

    2009-06-01

    As EDF and Areva have been developing for several years a strategy exclusively based on a nuclear revival in the world, this document proposes a synthesis of a study in which the author describes and analyses this strategy, as well as the actual trade perspectives of the sector, and outlines the many uncertainties regarding development projects. It addresses the financial and political context for EDF (a record indebtedness) and Areva (an inability to face investments) and outlines the supporting role of the Coface (the only way for the French government to support EDF and Areva). It highlights and discusses the failures of both ERP projects, in Flamanville (cost overruns and consequences) and in Finland. It addresses the actual status of markets, notices that France's strategy (lifetime extension for the existing reactors) implies that the construction of new EPRs might finally be postponed, that which would mean a loss of prospects for Areva and a catastrophe for the EPR program. It comments the commitment of EDF in the UK and outlines that the success of the development of new nuclear plants still depends on public subsidies which are not yet decided. The author considers that investments made by EDF in the USA seem rather speculative, and outlines that there are still financial issues and uncertainties like in the UK. The presence and activities of EDF and Areva in China are also commented, and more briefly for the rest of the world

    The CO 2 emissions of EDF group (EDF-France + EDF-energy (UK) + Hidrocantabrico (Spain) + EnBW (Germany)) soared by 53% in 2002 which is due to the purchase of british and spanish electricity sub-companies using fossil energies. Despite this sharp increase EDF remains one of the most competitive electricity companies in Europe concerning greenhouse gas emissions. EDF group is the first electricity company in Europe, it generates 22% of the electricity produced in E.U and contributes to CO 2 emissions with a rate of 101 Kg CO 2 /MWh which 3 times less than the average rate of 20 other European companies (358 Kg CO 2 /MWh). This result is due to the large part of nuclear power in the French energy mix. The best electricity companies as far as CO 2 emissions are concerned are Statkraft (Norway) with 0 Kg CO 2 /MWh (100% hydrology) and British-energy (U.K) with 75 Kg CO 2 /MWh (75% nuclear power). At the other end we have the DEI company (Greece) with 863 Kg CO 2 /MWh (100% lignite). (A.C.)

  4. MOX and UOX PWR fuel performances EDF operating experience

    International Nuclear Information System (INIS)

    Provost, Jean-Luc; Debes, Michel

    2005-01-01

    Based on a large program of experimentations implemented during the 90s, the industrial achievement of new FAs designs with increased performances opens up new prospects. The currently UOX fuels used on the 58 EDF PWR units are now authorized up to a maximum FA burn-up of 52 GWd/t with a large experience from 45 to 50 GWd/t. Today, the new products, along with the progress made in the field of calculation methods, still enable to increase further the fuel performances with respect to the safety margins. Thus, the conditions are met to implement in the next years new fuel managements on each NPPs series of the EDF fleet with increased enrichment (up to 4.5%) and irradiation limits (up to 62 GWd/t). The recycling of plutonium is part of EDF's reprocessing/recycling strategy. Up to now, 20 PWR 900 MW reactors are managed in MOX hybrid management. The feedback experience of 18 years of PWR operation with MOX is satisfactory, without any specific problem regarding manoeuvrability or plant availability. EDF is now looking to introduce MOX fuels with a higher plutonium content (up to 8.6%) equivalent to natural uranium enriched to 3.7%. It is the goal of the MOX Parity core management which achieve balance of MOX and UOX fuel performance with a significant increase of the MOX average discharge burn-up (BU max: 52 GWd/t for MOX and UOX). The industrial maturity of new FAs designs, with increased performances, allows the implementation in the next years of new fuel managements on each NPPs series of the EDF fleet. The scheduling of the implementation of the new fuel managements on the PWRs fleet is a great challenge for EDF, with important stakes: the nuclear KWh cost decrease with the improvement of the plant operation performance.

    Electricite de France (EDF) and Electric Power Research Institute (EPRI) have been involved in human reliability studies over the last few years, in the context of improvements in human reliability assessment (HRA) methodologies, and have been following a systematic process since 1982 which consists of addressing the following five ingredients: - First, classify human interactions into a limited number of classes. - Second, introduce an acceptable framework to organize the application of HRA to PRA studies. - Third, select approach(es) to quantification. - Fourth, test promising models. - Fifth, establish an appropriate data base for tested model(s) with regard to specific applications. EPRI has just recently completed Phase I of the fourth topic. This primarily focused on testing the fundamental hypotheses behing the human cognitive reliability (HCR) correlation, using power plant simulators. EDF has been carrying out simulator studies since 1980, both for man-machine interface validation and HRA data collection. This background of experience provided a stepping stone for the EPRI project. On the other hand, before 1986, EDF had mainly been concentrating on getting qualitative insights from the tests and lacked experience in quantitative analysis and modeling, while EPRI had made advances in this latter area. Before the EPRI Operator Reliability Experiments (ORE) project was initiated, it was abundantly clear to EPRI and EDF that cooperation between the two could be useful and that both parties could gain from the cooperation

  9. Ensuring the sustainability of EDF power plant operating capacity

    2009-01-01

    The life extension of the power plants is considered whereas EDF must face an acceleration of the retirement rates due to the fact that the first generations of the baby-boom are ageing 60 years, now. Between 2000 and 2006, EDF gradually set up a system of management of competencies. On the one hand, EDF moved from logic of relatively standardized training to a more individualized logic of acquisition of competencies. In addition, the objective of maintenance of internat competencies defined in 2000 was supplemented in 2003 by a prospective dimension intended to anticipate the departures in inactivity. Then in 2006 competencies of sub-contractors were taken into account. During this period I.R.S.N. has assessed 3 times this system of management. This article briefly presents the principal lessons driven from these evaluations. It accounts for the undeniable effort made by EDF to ensure the maintenance of its competencies. However, it stresses that a high level of vigilance is still needed because it is not stabilized already. (author)

    2010-01-01

    As part of the regulatory environmental monitoring around its nuclear power plants, EDF carries out every year more than 40.000 measurements. In addition EDF performs more precise radioecological surveys on all its sites. This monitoring shows the minor incidence of EDF's nuclear power plants on the environment and a general decrease of gamma emitters radionuclides in the environment. These results confirm the efforts lead by EDF to minimise its impacts on the environment, linked to an efficient waste management and demonstrate the good operating standards of its plants. On a qualitative viewpoint, significant efforts on both metrology and organization have lead to improved measurements capabilities, in order to achieve NF EN ISO/CEI 17025 standard compliance. More recently, a similar approach has been implemented with sampling methods. While today the level achieved in the number and quality of measurement complies with the objectives of the monitoring of the impact of the nuclear power plants on the environment, the results of this monitoring should be presented to the public with more pedagogy to give an adequate answer to their expectations. The new questions that will undoubtedly be raised by the recent availability of this information on the Internet should reinforce this dialogue and should also be the opportunity to improve the quality of our communication.

  14. The safety approach in the operation of EDF power plants

    International Nuclear Information System (INIS)

    Bertron, L.; Mira, J.J.

    1988-01-01

    To get a view on what is involved in maintaining a high level of safety in the operation of EdF nuclear power plants, it may be recalled that in 1987, 76 % of the EdF production was nuclear. The nuclear plants include thirty-four standard PWR 900 plants, fourteen PWR 1300 plants, the 305 MW SENA PWR, the four 500 MW GCR: CHINON A3 plant, St-LAURENT A1 (390 MW), A2 (450 MW) and BUGEY 1 (540 MW), the 233 MW PHENIX fast breeder reactor and the CREYS-MALVILLE 1200 MW fast breeder reactor, now being prepared for a new startup after the 1987 incident. So the importance of a safe operation of this investment is considerable for EdF, which is the designer, owner, industrial architect and operator. According to the French regulations, EdF is responsible for the safe operation of its power plants. A considerable human component is also at stake, as the safe operation of plants implies all the personnel to varying degrees. There are 15,000 such employees, all of whom have to be trained, competent and motivated. The operation of this system for 340 reactor-years has to-date resulted in no incident of any significant impact on the environment. Right from the start, safety in operation has always been an essential and clearly stated priority. Among other lessons the Three-Mile Island and Chernobyl accidents have reinforced the conviction that the human factors, the man-machine interface, and the safety culture were determining elements. With forty-eigh PWR plants in service, the problem is to maintain safe operation of a system now running at cruising speed, but also including some units (particularly the GCRs) that must be prepared for decommissioning. In addition EDF has to demonstrate the safe operations of CREYS MALVILLE, fast breeder reactor

    EDF is upgrading its distribution remote-control systems. By the end of 1997 three centres run by EDF GDF Services (in Paris, Lyon and Versailles) will be equipped with a Siemens SCADA system. A number of functions developed by EDFF as part of work on the Austral project (event reporting, diagnostics, service resumption assistance, etc.) will then be implemented on the SCADAs at Lyon and Versailles. At the same time, an alternative upgrade solution is being investigated for the 75 computerized remote-control systems (CRSs) developed by EDF around 1980. In December 1996, EDF started experimentation on a new prototype SCADA at the Nimes centre. For this prototype, the existing real-time CRS software, will all its functionalities, was ported onto a Unix workstation. High-reliability communication with the primary substations is provided by a meshed X25 transmission network, and all data on primary substations and the medium-voltage grid is managed by a new configurator. To facilitate incident analysis, an off-the-shelf user interface will provide graphic representations of the grid in different degrees of detail, with dynamic colour coding of feeders. The new architecture for the prototype SCADA implements object-oriented data modelling of the grid components. Applications modules -developed by EDF (e.g. Austral functions) or third-party manufacturers (e.g. user interface with dynamic colour-coding of grid features) -will then be able to access this data much more easily than they did on the previous architectures, which used remote procedure calls. This new approach will be one of the first concrete applications of recent EPRI and IEC work on open upgradeable remote-control systems. (Author)

  17. Best Speed Fit EDF Scheduling for Performance Asymmetric Multiprocessors

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available In order to improve the performance of a real-time system, asymmetric multiprocessors have been proposed. The benefits of improved system performance and reduced power consumption from such architectures cannot be fully exploited unless suitable task scheduling and task allocation approaches are implemented at the operating system level. Unfortunately, most of the previous research on scheduling algorithms for performance asymmetric multiprocessors is focused on task priority assignment. They simply assign the highest priority task to the fastest processor. In this paper, we propose BSF-EDF (best speed fit for earliest deadline first for performance asymmetric multiprocessor scheduling. This approach chooses a suitable processor rather than the fastest one, when allocating tasks. With this proposed BSF-EDF scheduling, we also derive an effective schedulability test.

    Due to the characteristics of the radiation they emit. alpha emitters are highly radio-toxic in terms of internal exposure but their low penetration makes them inoffensive in terms of external exposure. In PWR power plants, α emitters are rare and the risk of contamination is particularly low. Until now, this risk has always been well controlled by the operator, and is not one of the main Radiological protection priorities within EDF. Nevertheless, requirements are always increasing, whether for the radiological protection of workers or the public, and have led EDF to reconsider the α risk, to ensure that the current provisions are adequate and to reinforce them if necessary. Therefore, a study of the α risk was started in 1999. (authors)

    1998-01-01

    Today, nuclear energy seems challenged by fossil energies, especially gas. However, the 1997's French government survey over energy options still places nuclear energy at the top of the list. The reasons why and how safe nuclear energy is still competitive are detailed in this paper. Most recent data from EDF's reactor will be discussed in terms of environmental and electricity production issues. The methods and management used to attain these results are explained for the different phases: design, construction, operation, and maintenance. The beneficial aspects over industrial development and local employment will be underlined. The influence of nuclear energy on EDF's financial results are shown, from past programme to today's operation. As most of french reactors are designed to adapt their output to the changes of load in the national grid, results are, as a conclusion, discussed in a small and medium electrical grid perspective.

    The optimisation of decontamination in EDF PWR power plants is the result of a permanent collaborative work between the plant operators, the subcontractors, central services of nuclear power division of EDF. This collaborative work enables the saving of all the feedback experience. The main operations carried out on nuclear sites like mechanical decontamination of valves, use of the ''EMMAC'' process on big components (replacement of steam generator, hydraulic parts of the reactor coolant pumps), use of foam on pools walls and divers in highly contaminated pools have been discussed. This paper shows that the choice of decontamination processes is very dependant on the components, on the dose rate reduction to be aimed and on the possibility to treat the waste on site. (authors)

  1. Pulsed neutron experiments on the graphite reactor EDF 3

    The use of pulsed neutron technique on the EDF 3 reactor has made possible to calibrate a rather great number of control elements. This technique which was tested on EDF 2 has given good results of which the interpretation is difficult due to the reactor size. As some processes ( geometrical location of sources and counters) were currently used to avoid this kind of difficulties another method for interpreting the results is proposed. The measurements are in good agreement with other experimental results obtained with the air-poisoning techniques and generally confirm the data obtained by preliminary computations. The experimental material was satisfying and seems particularly adapted to the problem to be solved. (author) [fr

    Structural mechanics studies at EDF have three goals: a better knowledge of the materials properties, an an improvement of the design, and a better in service surveillance of the components. This study has lead EDF to perform a large investment to make possible the fatigue survey of the primary circuit. This investment is of 10 men-years for the mechanical studies. A cumulative bookkeeping of the transients is now in action at Fessenheim I and II, Bugey II to V, Tricastin I, Gravelines I, Dampierre I. A catalog of the transients easy to use will be provided to each unit in the near future. The design of the new four loop plants will take advantage of a new catalog of the design transients, this catalog being used for the purpose of the design and the bookkeeping of the transients. Experimental and theoretical investigations concerning the vibrations of PWR internals and primary circuit have been carried out at Fessenheim I, Bugey V and Tricastin I . As a result of these studies and complementary studies on Safran mock-up, EDF has been able to define with FRAMATOME and CEA a monitoring system to meet the requirements of the safety authorities. The monitoring system is divided in to three parts: loose - parts detection system accelerometers; monitoring of reactor internals by neutron noise measurements; monitoring of heavy components vibrations by accelerometers. This system is now installed in all PWR units. Some developments are in progress at EDF mainly at the Directorate of Research and Development to improve the procedures of the control and to define the criteria for an early diagnostic of the anomalies. The major reports are Surveillance du comportement vibratoire des composants de circuit primaire; Vibration studies on a three loop PWR internals model; and Nuclear Reactor Surveillance - Neutron noise measurements and vibrations analysis on French PWR Internal structures

    French nuclear power has a bright future ahead, as a major contributor to the limitation of CO 2 emissions in the European Union, and as a cheap way of balancing the electricity supply. Of course, this future could be called into question if public no longer trusted us. This means we need to be stringent on the issues of safety, radiological protection of workers and maintenance. EDF will follow the debate raised by the French government on nuclear energy, through an attitude of openness and constant exchange of view ports, in order to give an objectively elaborated and clear answers to the questions raised by our industrial activities, and their future. EDF wants to answer these questions not only in technical, economic and scientific terms, but also by taking into account people's specific concerns, their expectations and their opinions. Citizens and customers should see a consistency in high standards between our ecological, technological, and commercial activities. It is only on this condition that EDF, and nuclear energy can keep the confidence they have earned in France. (author)

    After a discussion of the general context in terms of evolution of the energy market (over-capacity related to the development of renewable energies, limited export perspectives, low prices), of difficult position for the nuclear sector in Europe (an inadequate business model, shutting down of always more plants), of perspectives for EDF (a difficult passage from a monopoly to a competitive market, and a constraining legal framework), this study reports an assessment of EDF's assets. In the next part, it addresses issues related to dismantling and to waste management for French nuclear reactors. It describes the context, outlines that dismantling charges have been under-provisioned, and that assessments made for waste management are not completely reliable, and also discusses consequences in terms of accounting. The cost of future investments is then discussed, with also their consequences in terms of accounting. Financial consequences are finally discussed

    Most corrosion that occurs in the circuits of a NPP is due: - either to inadequate conditioning; ammonia or morpholine levels are too low, sometimes too high, hydrazine level is too low compared to the air ingress levels, or -to the pollution of the water; for instance, sodium coming from the make-up water demineralization system or cooling water ingress, and oxygen coming from the air ingress to the condenser. At EDF, chemistry is mainly ensured by automatic on-line monitors (pH, conductivity, sodium, oxygen) rather than by extensive sampling and manual analyses. (author). 1 tab., 3 refs

    Concrete structures which are encountered at EDF, like all civil engineering structures, age. In order to adapt the maintenance conditions of these structures, particularly to extend their service life, and also to prepare constructions of future structures, tools for predicting the behaviour of these structures in their environment should be available. For EDF the technical risks are high and consequently very appropriate R and D actions are required. In this context the Direction des Etudes et Recherches (DER) has developed a methodology for analysing concrete structure behaviour modelling. This approach has several aims: - making a distinction between the problems which refer to the existing models and those which require R and D; - displaying disciplinary links between different problems encountered on EDF structures (non-linear mechanical, chemical - hydraulic - mechanical coupling, etc); - listing of the existing tools and positioning the DER `Aster` finite element code among them. This document is a state of the art of scientific knowledge intended to shed light on the fields in which one should be involved when there is, on one part a strong requirement on the side of structure operators, and on the other one, the present tools do not allow this requirement to be satisfactorily met. The analysis has been done on 12 scientific subjects: 1) Hydration of concrete at early ages: exothermicity, hardening, autogenous shrinkage; 2) Drying and drying shrinkage; 3) Alkali-silica reaction and bulky stage formation; 4) Long term deterioration by leaching; 5) Ionic diffusion and associated attacks: the chlorides case; 6) Permeability / tightness of concrete; 7) Concretes -nonlinear behaviour and cracking (I): contribution of the plasticity models; 8) Concretes - nonlinear behaviour and cracking (II): contribution of the damage models; 9) Concretes - nonlinear behaviour and cracking (III): the contribution of the probabilistic analysis model; 10) Delayed behaviour of

    According to provisions of privatisation and shareholders agreement Stredoslovenska energetika (SSE), a.s., Zilina should be managed by the largest European power concern Electricite de France (EdF). But so far, one year after the acquisition, the only French member of the Supervisory board is its Chairman Patrick Luccioni. The Board has 5 members and two of them are German - Peter Weis and Martin Konerman. The latter joined in September this year. He came to Slovakia after years spent in Boards of Hungarian distribution companies - Elmu in Budapest and Emasz in Miskolcz. The name of Peter Weis still can be found on the web page of Emasz on the list of members of Supervisory Board. Strategic partner in both the mentioned Hungarian distribution companies is the third largest player on the German energy market - Energie Baden-Wurttemberg (EnBW). The French concern with its 35-percent stake is the biggest individual shareholder of the EnBW. EdF is reassessing its international projects. Due to an investment embargo the French will not be among the prospects interested in acquisition of Slovenske elektrarne, a.s., Bratislava but the company management has also announced its intention to sell its minority stakes in northern and eastern Europe. The Paris head office of EdF announced its decision in the time when privatisation of Slovak distribution companies was culminating. And so in order to maintain its influence the 49-percent stake in SSE together with management control over the company will be transferred to EnBW. Spokeswoman of EnBW, Petra Wollmer did not say the company would not plan any acquisitions in area of its core business but stressed that these would have to be thoroughly examined. She did not wish to comment on any potential plans the company may have in Slovakia or that would relate to changes in the management bodies of SSE.

    Highlights: ► EDF-1 participates early adipogenesis in 3T3F442A cells induced with Staurosporine/Dexamethasone. ► EDF-1 associates with CaM and Cn, most likely inactivating Cn. ► EDF-1/CaM complex seems to prevent NFATc1 activation by Cn. ► EDF-1 regulates the Cn/CaM/NFATc1 pathway during adipogenesis. ► EDF-1 may regulate the activation of Cn through a complex formation with CaM. - Abstract: The endothelial differentiation factor-1 (EDF-1) is a calmodulin binding protein that regulates calmodulin-dependent enzymes. In endothelial cells, this factor can form a protein complex with calmodulin. We analyzed the relationship between this factor and the members of calmodulin/calcineurin/nuclear factor of activated T-cells (NFAT) signaling pathway during adipogenesis of 3T3-F442A cells. We found that the expression of edf1 is upregulated during early adipogenesis, whereas that of calcineurin gene is lowered, suggesting that this pathway should be downregulated to allow for adipogenesis to occur. We also found that EDF-1 associates with calmodulin and calcineurin, most likely inactivating calcineurin. Our results showed that EDF-1 inactivates the calmodulin/calcineurin/NFAT pathway via sequestration of calmodulin, during early adipogenesis, and we propose a mechanism that negatively regulates the activation of calcineurin through a complex formation between EDF-1 and calmodulin. This finding raises the possibility that modulating this pathway might offer some alternatives to regulate adipose biology

    2012-01-01

    This report is destined for the President of EDF with the purpose of informing him of the judgement the Inspector General has about the nuclear safety and radiation protection within the EDF Group. It is also intended for all who, in any way, play a role at EDF in improving nuclear safety. It may also prove useful to those outside the company who work in the nuclear field or indeed any branch of industry where there are risks to be managed and who wish to participate in the debate. It also contributes to the pool of information shared with the other nuclear operators under the auspices of WANO. The continuous improvement of nuclear safety results is a fundamental commitment of the EDF Group. This is notably reflected in a policy of transparency, whether in France, Britain, America or China. This document constitutes an example of this, offering an independent view of the operational situation. It is based on facts and findings derived in EDF's contacts with field staff and meetings with the decision makers, managers, medical personnel and players on both sides of this industry as well as outside stakeholders, especially contractor companies. The resulting snapshot of the situation in the field is particularly instructive. This report therefore concentrates more on problems and weaknesses rather than strengths and progress, except as concerns happenings outside France, where the focus is more on good practices than difficulties. Contents: 1 - The view from the Inspector General of EDF about the nuclear safety in the EDF group; 2 - A panorama of 2011: The management, The state of the installations, Maintenance of the French nuclear power plants, Relations with the French nuclear safety authority (ASN), The EPR projects, The players in the fields of health and safety, Radiation protection, Fire prevention and fire fighting, Increasing nuclear power plant security, Decommissioning; 3 - Nuclear safety management; 4 - The Fukushima Daiichi accident; 5 - Training to

    This report presents a synthesis of the most recent information on the both public companies, EDF and AREVA, within the context of their industrial sector. While discussing hypotheses and assessments of future expenses, the report outlines that future expenses related to the electronuclear activity are well provisioned in the accounts of both companies, but that their value is probably under-estimated. As far as EDF is concerned, the authors outline that the international development strategy impacted investment and partnership choices, and that the company should review this posture within a new context. As far as Areva is concerned, they think that the company possesses the required assets to be revived, but this requires rigorous financial and industrial choices

    This technical report reviews the work which has been necessary for defining the EDF-2 fuel element. After giving briefly the EDF-2 reactor characteristics and the preliminary choice of parameters which made it possible to draw up a draft plan for the fuel element, the authors consider the research proper: - Uranium studies: tests on the passage into the β phase of an internal crown of a tube, bending of the tube under the effect of a localized force, welding of the end-pellets and testing for leaks. The resistance of the tube to crushing and of the pellets to yielding under the external pressure have been studied in detail in another CEA report. - Can studies: conditions of production and leak proof testing of the can, resistance of the fins to creep due to the effect of the gas flow. - Studies of the extremities of the element: creep under compression and welding of the plugs to the can. - Cartridge studies: determination of the characteristics of the can fuel fixing grooves and of the canning conditions, verification of the resistance of the fuel element to thermal cycling, determination of the temperature drop at the can-fuel interface dealt with in more detail in another CEA report. - Studies of the whole assembly: this work which concerns the graphite jacket, the support and the cartridge vibrations has been carried out by the Mechanical and Thermal Study Service (Mechanics Section). In this field the Fuel Element Study Section has investigated the behaviour of the centering devices in a gas current. The outcome of this research is the defining of the plan of the element the production process and the production specifications. The validity of ail these out-of-pile tests will be confirmed by the in-pile tests already under way and by irradiation of the elements in the EDF-2 reactor itself. In conclusion the programme is given for improving the fuel element and for defining the fuel element for the second charge. (authors) [fr

    Full text: EDF Energy Nuclear New Build (NNB) is building two EPR reactors at Hinkley Point C in Somerset in the United Kingdom that will provide reliable, low carbon electricity to meet approximately 7% of the UK’s electricity needs. The Hinkley Point C project is well advanced. It has achieved planning consent, design approval for the EPR reactor and a nuclear site license. There is a well-developed supply chain with identified preferred bidders who are already heavily involved in construction planning. Training for needed skills is underway and industrial agreements with trade unions are in place. NNB has the unique opportunity to set Knowledge Management behaviours, culture, and standards for the Hinkley Point C project from project inception instead of working to change them, such as on an operational site.

  3. EDF's nuclear safety approach for pressurized water reactors

    International Nuclear Information System (INIS)

    Tanguy, P.; Kus, J.P.

    1987-01-01

    The realization of the important French program fifty-four units equipped with pressurized water reactors in service, or under construction-had led to the progressive implementation of an original approach in the field of nuclear safety. From an initial core consisting of the deterministic approach to safety devised on the other side of the Atlantic, which has been entirely preserved and often specified, further extras have been added which overall increase the level of safety of the installations, without any particular complications. This paper aims at presenting succinctly the outcome of the deliberation, which constitutes now the approach adopted by Electricite de France for the safety of nuclear units equipped with pressurized water reactors. This approach is explained in more detail in EDF's 'with book' on nuclear safety. (author)

    After having recalled the context of the Messmer plan of 1974 according to which the roles of the different actors of the nuclear sector were clearly distributed, this article describes and comments the evolution of this context, notably after the N4 threshold has been reached: the French industry has lost many experts (they are retired), the concurrence has evolved as well as relationships between clients and providers. The article outlines that a new balance between the main actors is now needed. It comments the case of the EPR, the emergence of new PWR concepts, the different roles EDF, AREVA, GDF-Suez or Total may have depending on the project (they can be client, investor, or operator). Principles for a new strategy and operation for this sector and its actors are formulated

    The exploitation of French hydroelectric dams is at the eve of a big upheaval. EdF, the historical operator, and GdF Suez the French number two of hydropower generation are going to face the strong competition of the big European energy groups. France will open 20% of its hydroelectric potential to competition in order to be in agreement with the opening of energy markets imposed by the European Union, and to increase by 10% the hydroelectric power as requested by the French government policy. The candidates will have to fulfill 3 criteria: investing to increase production, reducing the environmental impacts, and accepting the principle of paying fees. However, some of the French dams suffer from serious pathologies and the health of thousands of small dams remains unknown because of the lack of available data. (J.S.)

  7. EDF requirements for hot cells examinations on irradiated fuel

    Segura, J.C.; Ducros, G.

    2002-01-01

    The objectives of increasing French Nuclear Power Plants (NPP) availability while lengthening the fuel irradiation cycle and reaching higher burnups lead EDF to carry out on site and hot cell examinations. The data issued from such fuel behaviour monitoring programmes will be used to ascertain that the design criteria are met. Data are also needed for modelling, development and validation. The paper deals quickly with the logistics linked to the selection and transport of fuel rods from NPP to hot cell laboratory. Hot cell PIEs remain a valuable method to obtain data in such fields as PCI (Pellet-Cladding Interaction), internal pressure, FGR (Fission Gas Release), oxide thickness, metallurgical aspects. The paper introduces burnup determination methods, inner pressure evaluation, preparation of samples for further irradiation such as power ramps for PCI and RIA (Reactivity Initiated Accident) testing. The nuclear microprobe of Perre Suee laboratory is also presented. (author)

    2014-01-01

    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

    2014-01-01

    Full Text Available In Real Time System, the achievement of deadline is the main target of every scheduling algorithm. Earliest Deadline First (EDF, Rate Monotonic (RM, and least Laxity First are some renowned algorithms that work well in their own context. As we know, there is a very common problem Domino's effect in EDF that is generated due to overloading condition (EDF is not working well in overloading situation. Similarly, performance of RM is degraded in underloading condition. We can say that both algorithms are complements of each other. Deadline missing in both events happens because of their utilization bounding strategy. Therefore, in this paper we are proposing a new scheduling algorithm that carries through the drawback of both existing algorithms. Joint EDF-RM scheduling algorithm is implemented in global scheduler that permits task migration mechanism in between processors in the system. In order to check the improved behavior of proposed algorithm we perform simulation. Results are achieved and evaluated in terms of Success Ratio (SR, Average CPU Utilization (ECU, Failure Ratio (FR, and Maximum Tardiness parameters. In the end, the results are compared with the existing (EDF, RM, and D_R_EDF algorithms. It has been shown that the proposed algorithm performs better during overloading condition as well in underloading condition.

  16. General review of diagnostic systems in EDF PWR units

    Chevalier, R.; Brasseur, S.; Ricard, B.

    1998-01-01

    Since the beginning of the French nuclear program, Electricite de France (EDF) has looked for ways to improve the availability and safety of its nuclear units. Therefore, monitoring systems on turbogenerators, reactor coolant pumps, primary circuits and core internal structures were designed by the Research and Development Division and implemented with technologies available during the 1970's. However, mainly because of difficulties for data interpretation by plant personnel, EDF subsequently decided to design and develop different tools to help plant operators to process a diagnosis: - a new generation of the Monitoring and Diagnostic System called PSAD, - expert systems for diagnosis on reactor coolant pumps (RCP) 'DIAPO' and turbogenerator units (TG) 'DIVA', - diagnostic guides written for most equipment pending the installation of new monitoring and diagnosis systems. The first version of PSAD, installed in five units, performs on-line monitoring of the turbogenerator shaft line, steam inlet valves, the reactor coolant pumps and the generator stator. The second version not yet implemented, will include Loose Part Detection (LPD) and Core Internal Structure Monitoring (CISM). The level of diagnosis achieved by PSAD depends on the component monitored. The TG and RCP monitoring functions of PSAD compute high level diagnosis descriptors such as natural frequencies and long term trends but do not elaborate a diagnosis automatically. However, a diagnostic assistance window is available on-line, whenever a warning message is displayed, whether for immediate or later action. The window presents a diagnostic approach whose purpose is to find the causes of the symptoms observed. This diagnosis approach is automated in the DIVA and DIAPO expert systems. Numerous potential faults can be identified for both systems thanks to a hierarchy of abnormal situations. The user interactively answers questions when information is needed to progress in the diagnosis. The resulting

    Full text: Starting on November 12 [art, Electricite de France launched its sixth advertising campaign for nuclear power, running in newspapers, magazines and on television. Inserts were published in 10 national daily newspapers and 7 magazines spread over a week period. A 40 second TV commercial will also be broadcast on 15 different channels between November 17 and December 7,1997. In a setting of renewed opposition to nuclear power, the 1997 campaign is a deliberate voicing of opinion and a response designed to instill responsibility and clearly inform the public over the results of the French nuclear electricity programme. The campaign, costing 22 million francs 9 million for the publication of inserts and 13 million for the TV spots) dwells heavily on the programme's comparative benefits for France. The TV commercial, created by the ad agency Callegari Berville, conveys communication based on proof. The rationale is informative in tone, stating that nuclear power ensures a part, of France's independence for energy, and that this is an inexpensive form of power, the results of which are visible on every electricity bill. What is more, nuclear power is a clean and non-polluting energy form. Through scenes of daily life and other imaginary scenes, the spot highlights the advantages nuclear power gives our country. The press campaign is a continuity of the campaign run in November 1996, with EDF using information developed in advertisements to respond to the major questions being asked by the public: how does nuclear power make the cost of electricity competitive? Why does, nuclear power create more jobs in France than other forms of energy? What is the impact of nuclear power on global warming? What do we do with nuclear waste? Why does nuclear power help put our trade balance in the black? The campaign also helps meet a demand by using a reply coupon to propose a number of documents such as 'Focus on the French Nuclear Electricity Programme' or 'Nuclear Waste in

  18. Introducing a new type of fuel in EDF reactors: Main issues. Introducing a New Fuel in EDF Reactors: Main Issues

    The main issues associated with the introduction of a new fuel design at an industrial level in EDF reactors are the following: in-core operational feedback, coherence of the nuclear fuel cycle and mixed cores. In-core operational feedback Once all possible experimental results have been obtained for a new fuel design, in-core qualification is necessary to assess its robustness and reliability prior to an industrial use. That qualification involves several steps to gather the relevant operational feedback at minimum risk: - irradiation of a few LTA's during a number of operating cycles greater than what would be needed on an industrial scale, with specific exams and rod extractions at the end of each fuel cycle: that first step is 5 to 6 years long; - loading whole reloads with the new fuel design in a dedicated reactor is then requested if the new fuel design is associated with a new structure design; in that case, only a full core with the new design will enable checking the behaviour of that fuel with respect to GTRF and assembly bow: that second step may take another 5 to 6 years. Altogether, the whole in-core qualification process might need more than 10 years. Considering that 10 other years could be necessary to finalise a design for LTA's, the qualification on an industrial case could be targeted around 2032. By then, the average age of EDF existing reactors will be 47 years old. Coherence of the nuclear fuel cycle The feasibility of a new fuel design needs to be assessed for each step of the fuel cycle. The specificity in the French nuclear fuel cycle stems from the spent fuel processing performed at La Hague plant, and the recycling of the recovered recyclable materials (uranium and plutonium). When a new fuel is used at an industrial scale, it is necessary to keep the feasibility of plutonium and reprocessed uranium recycling safe, taking into account the reactors safety limitations. For example, the increase in the average fuel assembly

    Vibration monitoring of components in nuclear power plants has been used for a number of years. This technique involves the analysis of vibration data coming from vital components of the plant to detect features which reflect the operational state of machinery. The analysis leads to the identification of potential failures and their causes, and makes it possible to perform efficient preventive maintenance. Earlydetection is important because it can decrease the probability of catastrophic failures, reduce forced outgage, maximize utilization of available assets, increase the life of the plant, and reduce maintenance costs. This paper documents our work on the design of a vibration monitoring methodology based on neural network technology. This technology provides an attractive complement to traditional vibration analysis because of the potential of neural networks to operate in real-time mode and to handle data which may be distorted or noisy. Our efforts have been concentrated on the analysis and classification of vibration signatures collected by Electricite de France (EDF). Two neural networks algorithms were used in our project: the Recirculation algorithm and the Backpropagation algorithm. Although this project is in the early stages of development it indicates that neural networks may provide a viable methodology for monitoring and diagnostics of vibrating components. Our results are very encouraging

    1993-10-01

    The studies carried out by EDF concerning the evaluation of the active magnetic bearing technology for their possible application to rotating machinery in electrical plants, and especially the 900 MW ''CP2'' turbogenerators which appear to have very little damping and vibrate noticeably during transients. Using a 4 tons test bench, the good quality of simulation applied to both permanent and transient conditions have been verified. Then, using a 10 tons test bench, the dimensioning concerns of the CP2 application were more precisely evaluated. It has been especially demonstrated that the accessible levels of force and damping were compatible with the application constraints. In a final 30 tons project, some innovative technological components have been used and the benefits from an optimization of the design of the magnetic parameters were determined. Specifications for a full-scale implementation have been therefore defined to enable the manufacturer to make a commercial offer. After a disappointing analysis of the offer, CP2 computations and studies were stopped but subsidiary studies were conducted: estimation of the damage risk under alternative bending of the CP2 rotors during their lifetime, prospective analysis of other possible applications of active magnetic bearings in power plants, development of a new vibratory test method through electromagnetic excitation. 5 figs., 6 refs

  1. The EDF/SEPTEN crisis team calculation tools and models

    International Nuclear Information System (INIS)

    De Magondeaux, B.; Grimaldi, X.

    1993-01-01

    Electricite de France (EDF) has developed a set of simplified tools and models called TOUTEC and CRISALIDE which are devoted to be used by the French utility National Crisis Team in order to perform the task of diagnosis and prognosis during an emergency situation. As a severe accident could have important radiological consequences, this method is focused on the diagnosis of the state of the safety barriers and on the prognosis of their behaviour. These tools allow the crisis team to deliver public authorities with information on the radiological risk and to provide advices to manage the accident on the damaged unit. At a first level, TOUTEC is intended to complement the hand-book with simplified calculation models and predefined relationships. It can avoid tedious calculation during stress conditions. The main items are the calculation of the primary circuit breach size and the evaluation of hydrogen over pressurization. The set of models called CRISALIDE is devoted to evaluate the following critical parameters: delay before core uncover, which would signify more severe consequences if it occurs, containment pressure behaviour and finally source term. With these models, crisis team comes able to take into account combinations of boundary conditions according to safety and auxiliary systems availability

  2. EDF: The revision of the electrical supply tariff system

    International Nuclear Information System (INIS)

    Kaczmarek, A.M.

    1982-01-01

    The article deals with proposals by EDF for restructuring their tariffs for the supply of electricity. The objective is to take account of probable developments in demand, notably the steadily increasing gap between the summer and winter rates of consumption, and in generation, notably the large increase in the fraction of the total load that is met by nuclear stations. It is estimated that by 1990 generation will be 70% nuclear, 16% hydraulic, 9% by coal and 4% by oil, nuclear generation being by far the cheapest. The general philosophy of the new tariffs is: to retain the two-part (kW and kWh) structure; to simplify tariffs for small consumers; to apply to large consumers sophisticated tariffs that accurately reflect true costs of supply; to make maximum demand rather than supply voltage the determining factor; tariffs will be geographically uniform except for a few very large consumers favourably situated with respect to key points in the network; to adopt special means to spread peak loads. The new tariffs and some additional related measures for influencing the incidence of electricity consumption are described in some detail. (C.J.O.G.)

    Fabre, J.P.

    2006-01-01

    Electricite de France (EdF) exploits about 475 dams over the whole French territory, the monitoring of which depends on the risks: natural risks, risks linked with the constructive works, and risks linked with the exploitation of the dam. Real situations are in general a combination of several type of risks. The monitoring of dams is based on visual inspection, sounding (measurements) and periodical tests of safety systems. The monitoring activity is placed under a quality assurance procedure. Two levels of redundant continuous monitoring are considered, one performed by the operator and the other by specialists. Monitoring devices are chosen according to their reliability, their stability, their simpleness and their robustness. The measured data are not numerous and well defined. Integrating phenomena are preferred. The statistical analysis of chronological series of data is performed periodically through simple, robust and general models allowing to determine the dam responses to stresses (reversible effects), and to obtain data in 'identical conditions' for a measurement of the evolution of the dam with time. The general trend is an increase of safety requirements with legislative changes, leading to more rigorous studies of dam risks. (J.S.)

  4. Standpoint of the EDF operator of nuclear power plants

    1996-01-01

    Safety and competitiveness are the sine qua non conditions to the durability of the nuclear industry in France, as in the other countries involved in electronuclear programs. Improving safety, increasing availability and mastering the costs are inseparable and interactive aims, and the cooperating actions are to be managed simultaneously. Another aim is the undivided attention given to radiation protection. The average annual collective dose per unit has slightly decreased since 1993 despite an increase in the circuit activity and the volume of the works. This result is not thoroughly satisfactory if compared to the performances carried out abroad on similar reactors. EDF has therefore decided to revise the establishments of contracts with the contractor companies on the following bases: - a lasting partnership bases on common aims, mutual obligations, and shared benefits; - complete and better integrated services, giving the companies a greater responsibility on the means to be implemented to achieve those aims; - pluriannual contacts. enabling the companies an improved insight of the future load, and thus giving them the opportunity to invest (in personnel training, in tools or in innovation processes, etc.); -permanent research in the field of the best technologies available in France and abroad, through supplier diversification and international experience feedback.

    1997-09-01

    To account for successive evolution of nuclear power plants emergency operation, EDF had several times to review PHRA methodologies. It was particularly the case when event-based procedures were left behind to the benefit of state-based procedures. These are the main ambitions of the project named MERMOS that started in 1996. The design effort for a new PHRA method is carried out by a multidisciplinary team involving reliability engineers, psychologists and ergonomists. The method, considered as the analysis tool dedicated to PHRA analysts, is one of the two outcomes of the project. The other one is the formalization of the design approach for the method, aimed at a good appropriation of the method by the analysts. The PHRA method is based upon a model of emergency operation called 'SAD model'. The formalization effort of the design approach lead to clarify and justify it. The model describes and explains both functioning and dys-functioning of emergency operation in PSA scenarios. It combines a systemic approach and what is called distributed cognition in cognitive sciences. Collective aspects are considered as an important feature in explaining phenomena under study in operation dys-functioning. The PHRA method is to be operational early next year (1998). Preliminary validation tests were performed quite early in the design process. These tests will set the grounds for the presentation of examples of the application of the method. (author)

  6. Innovative Approaches to Knowledge Management in EDF Energy Generation

    2016-01-01

    Full text: Organizational learning is a key discipline in the safe, sustainable operation of civil nuclear fleet. In order to have an effective organizational learning culture a free flow of information is required. To facilitate this free flow of information and ideas EDF Energy Nuclear Generation created the concept of the Organizational Learning Portal (OLP). The OLP was created to remove existing barriers to knowledge sharing and allow easy exchange of information and ideas. To transfer existing data from legacy systems onto the OLP required a considerable effort, to ensure that information and knowledge was preserved and available to recall easily for future use. The OLP, was designed using the latest ‘App’ design to promote accessibility, in line with contemporary information portals and applications sites to ensure a positive and intuitive user journey. A key operational use of the OLP is for accelerated learning, after significant events, e.g., reactor Trips or SCRAM. Additional functionality within the OLP allows implementation of video OPEX and cataloguing of information sources. The OLP was recognized in the 2015 Operational and Safety Assessment Readiness Team as a Best Practice. (author

  7. Seismic isolation of nuclear power plants - EDF's philosophy

    Coladant, C.

    1989-01-01

    The elastomer bearing pads used since 1963 as supports for prestressed concrete pressure vessels (PCPVs) was quickly chosen by Electricite de France (ED) to improve the capability of nuclear power plants (NPPs) to withstand strong earthquakes and to reduce the seismic loads on structures and equipment. The standardized units for 900 and 1,300 MW(e) pressurized water reactor (PWR) plants have moderate seismic design loads of 0.2 and 0.15 g, respectively. These design loads were exceeded by the site dependent spectra of Cruas (France) and Koeberg (South Africa). To keep the plant design unchanged and to take the advantages of standardization, these units were put on laminated bearings with or without sliding plates. For the future French 1,500 MW(e) fast breeder reactors (FBRs), which are more sensitive to seismic loads, the base isolation is considered by EDF at the beginning of the design, even for low ground motions of 0.1 g. The buildings are placed on laminated bearings while the reactor block is supported by springs and dampers. The isolated plant has identical costs as a conventional design such as SPX1 at Creys-Malville

    Full Text Available El matte painting es una técnica de efectos especiales utilizada para la creación de escenarios simulados mediante la combinación de un metraje rodado y un fragmento pintado. Dado que esta técnica ha constituido un recurso frecuente desde los orígenes del cine en propuestas narrativas muy diversas, cabría preguntarse si ha experimentado una distinta interpretación por parte de los diferentes regímenes de escritura cinematográfica o si, por el contrario, ha sido aplicado de una forma más o menos homogénea en todos ellos. ¿Cómo han interpretado los regímenes clásico, barroco, moderno, postmoderno y el actual neobarroco digital este efecto especial? Los resultados muestran claramente cómo cada régimen ha moldeado y adaptado sus pinturas de acuerdo a su particular concepción del espacio y el escenario.

    2009-01-01

    Full Text Available Diversas investigaciones coinciden en señalar que la elevada ansiedad frente a los exámenes está asociada a la baja habilidad para el estudio y al uso de estrategias superficiales de procesamiento de la información, existendo influencias recíprocas entre dichas variables. De acuerdo a esta perspectiva, se evaluó el uso de estrategias de aprendizaje en 816 estudiantes universitarios con elevada, media o baja ansiedad frente a los exámenes. Adicionalmente, se analizaron las relaciones entre las cuatro dimensiones de la ansiedad y las estrategias de aprendizaje. Los estudiantes con elevada ansiedad utilizaron más frecuentemente estrategias de repetición y búqueda de ayuda académica y los de baja ansiedad, estrategias de estudio reflexivo. La falta de confianza correlacionó negativamente con estrategias de estudio reflexivo, repetición, búsqueda de ayuda académica y regulación del tiempo y esfuerzo. En sentido opuesto, la preocupación se asoció positivamente con tres de estas estrategias.

  11. EDF's ageing management program for cooling towers

    International Nuclear Information System (INIS)

    Roure, T.; Crolet, Y.

    2015-01-01

    EDF operates a large fleet of cooling towers for its thermal and nuclear plants. Proactive maintenance strategies require ranking the towers according to the risk of failure and the observed damage. The ranking includes monitoring data such as: foundation settlements, material properties, quantified crack patterns, shell deformation, meteorological data, and corrosion. The numerical tool suite includes a finite element analysis of each tower under thermal and mechanical loadings and a corrosion predicting tool, based on carbonation. The first module computes the behavior of cooling towers under five types of loading: soil differential settlement, self-weight, moisture transport, temperature and wind. By comparison with the ultimate resisting capacity of the reinforced concrete cross section, a risk index map is produced for each tower. This risk index is used to rank the cooling towers and then to identify which structures should be monitored more closely or reinforced - if needed - first in the case of an extended operating life. The second module aims to anticipate the corrosion depth of reinforcement steel of the towers in the future. Examination of the existing carbonation is currently done for each structure and evolution of the carbonation depth is computed so as to predict with reasonable assurance when carbonation reaches the rebars. A prediction of the eventual cross-section loss of rebars is then made for long term analysis (i.e. up to 60 years of operating life). When corrosion is predicted the first module takes into account this loss and computes the behavior of the predicted corrosion damaged structure under the same loadings. (authors)

  12. Nuclear non-proliferation and security culture within EDF nuclear fleet

    International Nuclear Information System (INIS)

    Debes, M.

    2013-01-01

    This document describes the nuclear non-proliferation strategy and the safety culture of EDF. The author lists all the mandatory rules and regulations at international and national levels EDF has to comply with. All these requirements are applied in EDF nuclear facilities through adequate procedures that assure a nuclear material accountancy, a follow-up of any item containing nuclear material in the facility, and internal controls. External independent controls are also performed. The EDF security policy goal is to protect human, material and knowledge assets, and to preserve operational capacity, competitiveness and public confidence, within national regulatory framework and regulation on 'vital importance facilities'. The treatment of events or incident (detection, analysis, lessons drawn, experience feedback) is a tool to progress, along with reporting, internal control process and audits. The security requirements cover the different related domains important to EDF industrial assets: security of employees against assaults; security of data according to their sensibility level; security of the information system and telecom; awareness and training of employees; relations with external suppliers or contractors; business premises; security of staff and projects abroad. For industrial facilities and grids (facilities of 'vital importance'...), the defense in depth principles are applied against the different threat scenarios. Security measures are studied at the design stage in a consistent way with nuclear safety measures, while taking into account the protective means deployed by public authorities. These risk analysis are periodically reassessed. The paper is followed by the slides of the presentation. (A.C.)

    1990-01-01

    The considerable, uninterrupted reduction in demand for conventional thermal power plants between 1980 and 1989 noticeably affected not only the structure of EDF generation mix and its related means but also its image in the field of environment. From environmental viewpoint, there is less frequent utilization of coal-fired thermal power plants from 1985 to 1988, and the correspondingly low level of pollutant rejects. This situation could not last for long since EDF might take two actions during the next decade concerning generation means renovation and environmental protection as a result of the expected rise in the demand duration of the coal-fired units. This paper deals only with the subject of environment. The authors first quantify the pollutant rejects (SO 2 , NO x ) before suggesting possible technical solutions aiming at reducing the emissions and how they could be applied to EDF coal-fired power stations. The low NO x combustion tests performed in BLENOD power plant are also presented

    French Electricity Company (EDF - Electricite de France) and the associated servicing companies, engaged in maintenance partnership from 1991, reinforce and expand their policy by undersigning a progress charter, to cope with the safety and nuclear sector competition issues. This charter stipulates the mutual engagements in the following sectors: 1. Transparency in calling for servicing; 2. Development of the intervenors' professionalism; 3. Improvement in forecasting activity tasks; 4. Radioprotection; 5. Safety and working conditions. The 55 reactors of the EDF nuclear stock are stopped annually for around 6 weeks for refueling. On this occasion the essential maintenance works necessary to ensure the optimal safety of the installations are carried out. The maintenance requires the intervention of 30,000 employees, 10,000 EDF agents and 20,000 external intervenors and represents an amount of 14 million working hours. The full maintenance expenses amounts up to 11 billion FF in 1996, 6 billion of which are assigned to external companies

    2017-10-15

    The announcement by French state-controlled utility EDF that it has added pound 1.5 bn (Euro 1.7 bn, $ 1.9 bn) to its estimated costs for two new reactors at Hinkley Point C, has led to questions about whether the government should rethink the project, with some politicians calling for it to be abandoned. EDF's announcement came less than two weeks after a report from the Government Accountability Office (GAO) said the government's deal for the two EPR units, now estimated to be costing pound 19.6 bn (Euro 22.3 bn, $ 25.5 bn), has locked consumers into a risky and expensive project with uncertain strategic and economic benefits. The UK's Energy Technologies Institute (ETI), in a report prepared before the EDF announcement, had already said the requirement to improve the predictability and affordability of new nuclear power plants has never been stronger.

  16. EdF speaks about economic advantages of fuel reprocessing as compared with interim storage

    International Nuclear Information System (INIS)

    Anon.

    1997-01-01

    The French company Electricite de France (EdF) will prefer nuclear fuel reprocessing and plutonium recycling to spent fuel storage also in the years after 2000. This option is economically advantageous if the proportional cost of reprocessing does not exceed 1900 FRF/kg heavy metal. Economic analysis shows that this is feasible. EdF will soon have to reprocess annually about 1000 Mt spent fuel to supply enough plutonium for MOX fuel fabrication to feed as many as 28 PWR units and the Superphenix reactor. Spent fuel reprocessing is seen as promising as long as the efficiency of the MOX fuel approaches that of natural uranium based fuel. The French national industrial, political and legal context of EdF operations is also considered. (P.A.)

    EDF decided in 2001 to implement immediate dismantling of its first generation nuclear plants. Seven years after this decision, the physical progress of the programme is 24% and is due to reach 50 % by 2013. This paper presents the experiences acquired in the fields of organization, project and programme management, purchasing strategies and waste management. Until now, the principal works involve Brennilis (Heavy water), ChoozA (PWR) and Creys Malville (fast breeder reactor). The detailed pre-project concerning the first of the six gas graphite reactors is complete and the call for bids process has been launched. The organization to manage projects, established at the De-construction and Environment Engineering Center (CIDEN), is effective and productive. Estimates of costs and expenses are coherent, which makes the forecasts put together to finance the programme secure. CIDEN has carried out significant engineering work over the last six years, making it possible to apply for the administrative authorizations which have now been obtained or are in the process of being obtained. Technical specifications are prepared at an optimized level of detail according to a contractual policy adapted to the complexity of the operations and the sharing of risk with manufacturers. The ChoozA contractualization process has been launched and the first dismantling work has begun in the nuclear auxiliary part. The main Brennilis contract will be completed in mid- 2008 and dismantling works will restart after renewal of the decree which was cancelled in mid-2007. Treatment of sodium from Creys Malville is about to begin, leading to elimination of the sodium risk by 2013. The very low activity waste (TFA) and low to medium activity waste (FA-MA) removal chains are operational. The intermediate activity/long lived (MA-VL) waste will be stored in a facility which will be brought into operational service in 2012. The graphite storage center is due to open between 2017 and 2019

    2012-01-01

    This article comments the results of recent invitation to tender for several offshore wind farms in France. Three sites were attributed to the Eolien Maritime France consortium (EDF, Dong Energy and Alstom), one to Ailes Maritimes (Iberdrola, Eole-Res and Areva). Huge investments, thousands of jobs and the construction of new factories are at stake. Areva and even more GDF Suez, the main looser of this tender process, feel that the choice has been made in favour of EDF. As these projects are still to be confirmed, others are foreseen to reach an offshore production of 6000 MW. French actors will also have to conquer foreign markets, notably in Great-Britain

    A stable and tunable single-longitudinal-mode (SLM) Brillouin/Erbium fiber laser (BEFL) with narrow linewidth is proposed and experimentally demonstrated. A uniform Bragg grating written in a segment of unpumped Erbium-doped fiber (EDF) is incorporated as an auto-tracking filter to achieve SLM operation. A length of 5 m pumped EDF is used to provide both Brillouin and linear gain in the cavity. The linewidth is measured to be 18 kHz and the lasing peak power fluctuation and wavelength shift are monitored less than 0.027 dB and 2 pm respectively.

    In 1997 the energy production of the French Electricity Company EDF (Electricite de France) reached the value of 457.7 billion kWh, of which 82% is nuclear, 14% hydraulic and 4% classical thermal power. The management of maintenance annual intervention allowed and availability of the nuclear sector of 82.6%. The safety level was also maintained at a high value. The quality of the supplied electricity has been improved continuously: the annual average interruption duration for low voltage supply has been reduced from 1.35 h in 1996 to 1.06 h in 1997. Sale volume in France (369.9 billion kWh) is 0.7% lower than in 1996. EDF remains the first electricity exporter in Europe. The EDF has strengthened in 1997 its international development. FF 4.2 billions have been invested in Europe, Latin America and Asia. A social policy has been developed in favor of employee, particularly, young people acting toward enterprise's development, better management and working time reduction. In the frame of its relation with the state the EDF Company has signed a new contract for the period 1997-2000 which will allow reaching its ambition: becoming a public service of reference in Europe and its promotion as leader in industrial services, in the electric sector of France and on the international market. The results of this first year has confirmed the course adopted. The report contains the following seven chapters: 1. Relations with the state and the evolution of the institutional frame; 2. The financial results and administration; 3. Technical results; 4. Development in France; 5. International development; 6. Social and human resources; 7. Environment.

    Infantile and juvenile scoliosis, among different types of spinal deformity, is still a challenge for pediatric orthopedic surgeons. The ideal treatment of infantile and juvenile scoliosis has not yet been identified as both clinicians and surgeons still face multiple challenges, including preservation of the thoracic spine, thoracic cage, lung growth and cardiac function without reducing spinal motion. Elongation, derotation, flexion (EDF) casting technique is a custom-made thoracolumbar cast based on a three dimensional correction concept. This cast offers three-dimensional correction and can control the evolution of the deformity in some cases. Spinal growth can be guided by EDF casting as it can influence the initially curved spine to grow straighter. This article aimed to provide a comprehensive review of how infantile and juvenile scoliosis can affect normal spine and thorax and how these deformities can be treated with serial EDF casting technique. A current literature review is mandatory in order to understand the principles of the serial EDF casting technique and the effectiveness of conservative treatment in young and very young patients.

    2015-11-01

    The French Court of Auditors reports the examination of the international strategy of the EDF group and of its mother company. It examines international activities undertaken by EDF out of France through its foreign subsidiary companies and joint ventures during the 2009-2013 period. After a description of the current EDF's international dimension, a recall of its international development between 1993 and 2008, a description of its situation in 2009 and of its recent developments (in 2014-2015), this report first addresses the main international operations undertaken by EDF between 2009 and 2013: acquisitions and cessions, withdrawal from the USA, strengthened positions in Italy and in the UK, China as an important development target, and modest investments in new energies and services. The second part analyses the contrasted financial results of this strategy: a reduced footprint of international activities on cash management and investments, and a negative impact of recurrent losses by some international activities. The third part shows that current requirements had more influence on the international strategy than anticipations on the medium and long terms: insufficient improvement of strategic governance, justifications to the strong presence abroad which are to be more deeply expressed, and a financial constraint on abroad manoeuvre margin. It outlines that expectations expressed by the French State and other shareholders did not have a real impact, and that the geography of target markets still need to be better justified

    1995-01-01

    In France, the anti-nuclear protest movement became a real problem after 1968, as new sites were sought. Initially, information on nuclear power involved communication by the entities responsible for building the plants. Once Government officials and politicians overcame their initial hesitation, their support, which underscores the continuity of France's energy policy, came to play a major role in the public acceptance of nuclear power. Electricite de France (EDF) then had to master the art of informing and communicating with the public. The change in the parliamentary majority in 1981 did not call into question the nuclear programme, and new plants were commissioned with relative ease. The situation changed dramatically with the Chernobyl disaster. It therefore became vital to establish an efficient structure for crisis communications, and transparency became crucial. The focus shifted from launching new plants to operating existing facilities and restoring public confidence. While not neglecting the general public, the emphasis was on certain strategic segments of the population, notably teachers and health care professionals. Advertising campaigns are today aimed at certain segments of the public, whose opinion could well shift in favour of nuclear power. Lastly, EDF, as power plant operator, has to realize the importance of providing information on nuclear waste. Starting from a strategic policy of informing politicians and senior decision makers, in 1974 EDF began to focus on providing information that would 'educate' the public. This information was issued via technicians who had no specific training in communications techniques. In addition to the need to explain and justify its projects, EDF had to adopt a policy of transparency, and to dispense with the esoteric language of specialists and their preference for secrecy. After Chernobyl, EDF's managers made communications with the 'outside world' an integral part of their jobs. Nuclear information became a

    2016-01-01

    Full Text Available Eshcerichia coli mazEF is a stress-induced toxin-antitoxin module mediating cell death and requiring a quorum-sensing (QS extracellular death factor (EDF, the pentapeptide NNWNN. Here we uncovered several distinct molecular mechanisms involved in its generation from the zwf mRNA encoding glucose-6-phosphate dehydrogenase. In particular, we show that, under stress conditions, the endoribonuclease MazF cleaves specific ACA sites, thereby generating a leaderless zwf mRNA which is truncated 30 codons after the EDF-encoding region. Since the nascent ribosome peptide exit tunnel can accommodate up to 40 amino acids, this arrangement allows the localization of the EDF residues inside the tunnel when the ribosome is stalled at the truncation site. Moreover, ribosome stalling activates the trans-translation system, which provides a means for the involvement of ClpPX in EDF generation. Furthermore, the trans-translation is described as a regulatory system that attenuated the generation of EDF, leading to low levels of EDF in the single cell. Therefore, the threshold EDF molecule concentration required is achieved only by the whole population, as expected for QS.

    Hiergesell, R.A.; Dixon, K.L.

    1996-06-01

    A water budget for the Par Pond hydrologic system was established in order to estimate the rate of groundwater influx to Par Pond. This estimate will be used in modeling exercises to predict Par Pond reservoir elevation and spillway discharge in the scenario where Savannah River water is no longer pumped and discharged into Par Pond. The principal of conservation of mass was used to develop the water budget, where water inflow was set equal to water outflow. Components of the water budget were identified, and the flux associated with each was determined. The water budget was considered balanced when inflow and outflow summed to zero. The results of this study suggest that Par Pond gains water from the groundwater system in the upper reaches of the reservoir, but looses water to the groundwater system near the dam. The rate of flux of groundwater from the water table aquifer into Par Pond was determined to be 13 cfs. The rate of flux from Par Pond to the water table aquifer near the dam was determined to be 7 cfs

    In 1997 the energy production of the French Electricity Company EDF (Electricite de France) reached the value of 457.7 billion kWh, of which 82% is nuclear, 14% hydraulic and 4% classical thermal power. The management of maintenance annual intervention allowed and availability of the nuclear sector of 82.6%. The safety level was also maintained at a high value. The quality of the supplied electricity has been improved continuously: the annual average interruption duration for low voltage supply has been reduced from 1.35 h in 1996 to 1.06 h in 1997. Sale volume in France (369.9 billion kWh) is 0.7% lower than in 1996. EDF remains the first electricity exporter in Europe. The EDF has strengthened in 1997 its international development. FF 4.2 billions have been invested in Europe, Latin America and Asia. A social policy has been developed in favor of employee, particularly, young people acting toward enterprise's development, better management and working time reduction. In the frame of its relation with the state the EDF Company has signed a new contract for the period 1997-2000 which will allow reaching its ambition: becoming a public service of reference in Europe and its promotion as leader in industrial services, in the electric sector of France and on the international market.

    Ageing management of Nuclear Power Plants is an essential issue for utilities, in term of safety and availability and corresponding economical consequences. Practically all nuclear countries have developed a systematic program to deal with ageing of components on their plants. This paper presents the ageing management program developed by EDF and that are compared with different other approaches in other countries (IAEA guidelines and GALL report). The paper presents a general overview of the programs, the major results, recommendations and conclusions. (author)

    Since 1974, EDF is placed between a communication scheme imposed for energy savings and an industrial strategy of massive investment in nuclear power. In ten years, the company managed to increase households electricity consumption without advertising, due in particular to electric heating. But strong tensions were generated by this situation and led the company to develop an institutional communication to the employees and to the general public

    In 1981, the EDF carried out an experiment with computer-assisted training (EAO). This new approach, which continued until June 1982, involved about 700 employees all of whom operated nuclear power stations. The different stages of this experiment and the lessons which can be drawn from it are given the lessons were of a positive nature and make it possible to envisage complete coverage of all nuclear power stations by computer-assisted training within a very short space of time [fr

  1. A Comparison between Fixed Priority and EDF Scheduling accounting for Cache Related Pre-emption Delays

    Full Text Available In multitasking real-time systems, the choice of scheduling algorithm is an important factor to ensure that response time requirements are met while maximising limited system resources. Two popular scheduling algorithms include fixed priority (FP and earliest deadline first (EDF. While they have been studied in great detail before, they have not been compared when taking into account cache related pre-emption delays (CRPD. Memory and cache are split into a number of blocks containing instructions and data. During a pre-emption, cache blocks from the pre-empting task can evict those of the pre-empted task. When the pre-empted task is resumed, if it then has to re-load the evicted blocks, CRPD are introduced which then affect the schedulability of the task. In this paper we compare FP and EDF scheduling algorithms in the presence of CRPD using the state-of-the-art CRPD analysis. We find that when CRPD is accounted for, the performance gains offered by EDF over FP, while still notable, are diminished. Furthermore, we find that under scenarios that cause relatively high CRPD, task layout optimisation techniques can be applied to allow FP to schedule tasksets at a similar processor utilisation to EDF. Thus making the choice of the task layout in memory as important as the choice of scheduling algorithm. This is very relevant for industry, as it is much cheaper and simpler to adjust the task layout through the linker than it is to switch the scheduling algorithm.

    1997-01-01

    Considering nuclear safety concepts applied to reactor design and preventive measures taken by EDF during operation, and although the probability of a nuclear accident, even minor, on a unit is very low, it still cannot be considered nil. Therefore, the operator must be prepared, if such an event should occur, by defining and implementing a 'crisis organisation' in cooperation with the Safety Authorities. The crisis organisation has been set up in order to master and control the accident, i.e. in order to prevent, in real time, the accident developing into a more serious situation and to limit the consequences regarding technical and radiological concerns. EDF crisis organisation is integrated into the current organisation at local level as well as at national level. In addition to the operation team in 'shifts', crisis organisation is based 'on-call' personnel available at home (local level) or within a restricted area (national level). This organisation includes Managers, Experts, Participants EDF (+FRAMATOME), each of the them working, in case of an emergency, in his field of skills

    The EDF (Electric Ducted Fan) rocket to launch requires a system of monitoring, tracking and controlling to allow the rocket to glide properly. One of the important components in the rocket is OBDH (On-Board Data Handling) which serves as a medium to perform commands and data processing. However, TTC (Telemetry, Tracking, and Command) are required to communicate between GCS (Ground Control Station) and OBDH on EDF rockets. So the design control system of EDF rockets and GCS for telemetry and telecommand needs to be made. In the design of integrated OBDH controller uses a lot of electronics modules, to know the behavior of rocket used IMU sensor (Inertial Measurement Unit) in which consist of 3-axis gyroscope sensor and Accelerometer 3-axis. To do tracking using GPS, compass sensor as a determinant of the direction of the rocket as well as a reference point on the z-axis of gyroscope sensor processing and used barometer sensors to measure the height of the rocket at the time of glide. The data can be known in real-time by sending data through radio modules at 2.4 GHz frequency using XBee-Pro S2B to GCS. By using windows filter, noises can be reduced, and it used to guarantee monitoring and controlling system can work properly.

  6. The management of the radioactive waste generated by the EDF nuclear power plants in service

    Lantes, B.; Beguin, St.

    2011-01-01

    From the very beginning of France's nuclear power programme, EDF has developed industrial-scale management of the waste it produces, which has constantly progressed in line with changes in the regulations and the available technology. This management process, improved thanks to feedback and experience, ensures that any risk of exposure, at every stage, from production to final disposal, is controlled. The guidelines adopted by EDF for sustainable management of its waste are as follows: -) reduce the quantity of waste, from the production stage and then through recycling and reprocessing; -) sort waste according to its nature and activity level, so that it can be processed and packaged appropriately and the appropriate long-term management solution implemented; -) package waste as soon as it is produced to prevent any risk of dispersion; -) store waste, pending decay or the availability of an appropriate disposal solution; -) transport and place waste in repositories, keeping it away from Man and the environment by means of engineered or natural barriers for as long as required for the radioactivity to decay to an acceptable level. Regarding short-lived waste produced during operating and maintenance activities at power plants in service, EDF currently implements fully-integrated industrial management solutions which are constantly being optimised in conjunction with its industrial partners.

    1989-01-01

    As one of the most important producers of nuclear electricity in the world, EDF is concerned by all the aspects of the transport of nuclear materials and more particularly by those related to the nuclear fuel cycle. EDF is not itself a specialist in this field and most of the transports along the nuclear fuel cycle is done for their own account by their usual partners such as COGEMA or TRANSNUCLEAIRE. Since the beginning of the French nuclear program, they have generally used for these transports casks that already exist on the market and which were well suited to their needs. Nevertheless, new and specific needs appeared during the progress of their nuclear program and have lead them to: study and build new casks or packages, use existing casks for new purposes, develop a device for the measurement of fuel assemblies burn up, develop a software to optimize the evacuation of irradiated fuel for reprocessing. The purpose of this paper is to describe these realization but as a preliminary, they will present briefly the importance of the transport of nuclear materials for EDF

    2012-09-01

    After a first implementation of zinc injection at Bugey 2 and Bugey 4, EDF decided to extend the program to other units of its fleet. 14 more reactors from the French fleet of 58 were chosen in order to - Reduce the radiation sources for curative or preventive (after SGR) reasons - Mitigate stress corrosion cracking on nickel alloys and reduce the rate of generalized corrosion - Prevent the risk of CIPS, mainly after a fuel management change. Zinc injection started on 9 new units in 2011, 1 unit in 2012 and will be extended to 4 other units before the end of 2013. To monitor the injection, EDF has defined a complete program concerning chemistry, radiation protection (dose rate and deposited activities measurements), materials (statistical analysis of SG tube cracks), fuel (oxide measurements) and waste (radiochemical characterization of filters). Reference units were chosen for each field because of the size of the fleet. This paper will detail the different monitoring programs on the EDF plants injecting zinc. (authors)

    2003-01-01

    The EDF ambition today is to be among the best electricity producers in the world. To do so, we have to take more responsibilities, to motivate and to give our employees a better level of competence, and to make them more involved in the culture and the success of our company. In order to reach these objectives a deeper analysis of the NPP training needs must be completed. Our answer, named 'Local Competencies Development System' (LCDS) consists in implementing a large decentralisation of the competencies management, done by the EDF Production Department in conjunction with the EDF Training Department. It takes place in a logical approach bound up with the historical development of our nuclear program. In addition to this LCDS a new organization of training centers instructors, in dedicated training teams, has been implemented in order to co-ordinate the different actions directly with the NPP. The purpose of this presentation is to take into account the LCDS on the operation personnel training side, a similar organization has been implemented for the maintenance side

    2015-01-01

    PhysioNet Sleep EDF database has been the most popular source of data used for developing and testing many automatic sleep staging algorithms. However, the recordings from this database has been used in an inconsistent fashion. For example, arbitrary selection of start and end times from long term recordings, data-hypnogram mismatches, different performance metrics and hypnogram conversion from R&K to AASM. All these differences result in different data sections and performance metrics being used by researchers thereby making any direct comparison between algorithms very difficult. Recently, a superset of this database has been made available on PhysioNet, known as the Sleep EDF Expanded Database which includes 61 recordings. This provides an opportunity to standardize the way in which signals from this database should be used. With this goal in mind, we present in this paper a toolbox for automatically downloading and extracting recordings from the Sleep EDF Expanded database and converting them to a suitable format for use in MATLAB. This toolbox contains functions for selecting appropriate data for sleep analysis (based on our previous recommendations for sleep staging), hypnogram conversion and computation of performance metrics. Its use makes it simpler to start using the new sleep database and also provides a foundation for much-needed standardization in this research field.

  12. Strengthening the radiation protection culture: a priority of EDF radiation protection policy

    Full text of publication follows: In order to improve the management of radiation protection at EDF nuclear power plants, the Human Factors Group of the Research and Development Division of EDF has performed some studies on the appropriation process of the radiation protection requirements. These studies have notably shown that an efficient application of the radiation protection requirements lies on a comprehension by all workers of the meaning of these requirements. Furthermore, they should not be applied under the constraint or because of the fear of a sanction, but the workers need to perceive and understand the benefits in terms of protection associated with the radiation protection requirements. The strengthening of the radiation protection culture is therefore a key element of the radiation protection policy developed by EDF. This culture lies on an awareness of the health risks potentially associated with low levels of ionising radiations, as well as on the knowledge of tools, techniques and good practices developed to control the level of exposures and improve the radiation protection. Various type of actions have been undertaken to reinforce among the relevant players (exposed and non-exposed workers, contractors, all levels of management,... ) an awareness of radiation protection in order to integrate it in their day to day work: elaboration of a 'radiation protection system of reference' explaining how the radiation protection regulatory requirements are applied at EDF, publication of a 'radiation protection handbook' available for all workers (including contractors), training sessions, creation of networks of specialists from the various nuclear power plants on specific radiation protection issues, organisation of feed-back experience forum, etc. Beyond these specific actions, i t is also important to ensure a support and an assistance on the field by dedicated specialists. In this perspective, the health physicists have to play a key role in order to

    EDF R and D has computer power that puts it amongst the top industrial research centers in the world. Its supercomputers and in-house codes as well as its experts represent important capabilities to support EDF activities (safety analyses, support to the design of new reactors, analysis of accidental situations non reproducible by experiments, better understanding of physics or complex system response, effects of uncertainties and identification of prominent parameters, qualification and optimization of processes and materials...). Advanced numerical simulation is a powerful tool allowing EDF to increase its competitiveness, improve its performance and the safety of its plants. On this issue, EDF made the choice to develop its own in-house codes, instead of using commercial software, in order to be able to capitalize its expertise and methodologies. This choice allowed as well easier technological transfer to the concerned business units or engineering divisions, fast adaptation of our simulation tools to emerging needs and the development of specific physics or functionalities not addressed by the commercial offer. During the last ten years, EDF has decided to open its in-house codes, through the Open Source way. This is the case for Code – Aster (structure analysis), Code – Saturne (computational fluid dynamics, CFD), TELEMAC (flow calculations in aquatic environment), SALOME (generic platform for Pre and Post-Processing) and SYRTHES (heat transfer in complex geometries), among others. The 3 open source software: Code – Aster, Code – Saturne and TELEMAC, are certified by the French Nuclear Regulatory Authority for many «Important to Safety» studies. Advanced simulation, which treats complex, multi-field and multi-physics problems, is of great importance for the assessment of nuclear safety issues. This paper will present 2 examples of advanced simulation using Code – Saturne for safety issues of nuclear power plants in the fields of R and D and

    International Nuclear Information System (INIS)

    Le Guen, Bernard

    2014-01-01

    Document available in abstract form only. As part of the operation of its nuclear power plants, EDF set up in the 80's an emergency response organisation together with the French public authorities aimed at managing the consequences, especially radiological of any events. This is based on the setting up of emergency plans involving both the operator and the public authorities, at local and national level, with both parties assessing the consequences of a radiological accident in the environment constantly enhanced as part of the continuous improvement process. As the Fukushima accident especially highlighted the relevance of having a response system available off site, this emergency response organisation has been strengthened both with equipment and human resources so as to be able to respond to major accidents further to external hazards. These resources have been designed to factor in a high level of radiological risk. The functions and responsibilities are clearly defined for any event occurring at a nuclear power plant. The operator shall be accountable for the actions to be taken on site concerning technical plant management, worker protection and rescue of casualties. The public authorities shall be accountable for all the measures to be taken off site, especially protection of the local population and environmental monitoring. The EDF emergency response organisation is based on enhanced equipment and human resources at site and corporate level supplemented with EDF corporate and non-EDF resources. The EDF emergency plan covers the situation where all the site units are affected. The decision to set up the nuclear rapid response taskforce was taken further to the Fukushima accident in 2011 and it has been operational since 2012. Integrated in the emergency response organisation, its main aim is to be capable of responding in less than 12 hours to reinstate water, electricity and air supply at the nuclear power plant where the accident has occurred. It is

    After resuming briefly the characteristics of the installations G2-G3 at Marcoule and EDF 1 at Chinon, the authors review the main aspects of the tests, the starting and the exploitation of these reactors. Among the various points examined, particular emphasis is given to the devices of original nature such as tubular fuel elements, flattening of the neutron flux by stuffing, behaviour of the reactor tanks and the cooling circuits, the blowers, unloading devices, regulation and functioning of the informations. This analysis deals equally with the performances obtained and the difficulties and the various incidents experienced during the initial starting period. Among the more interesting results, the progressive increase in the power of the Marcoule reactors is mentioned, obtained through a better knowledge of the parameters covering the functioning of the reactors such as the distribution of the flux and the temperatures etc... acquired during the course of the exploitation of the reactor. The conclusion reached by the authors is that the experience gained on these installations has shown: - that during an initial period, adjustments became necessary, all of which turned out to be possible, - that an analysis of their functioning has permitted the progressive movement towards a truly industrial exploitation. (authors) [French] Les auteurs, apres un bref rappel des caracteristiques des installations G2 - G3 de MARCOULE et E.D.F. 1 de CHINON, passent en revue les principaux aspects des essais, de la mise en service et de l'exploitation de ces centrales.

    In 1990, EDF launched a Reliability-Centered Maintenance project for its nuclear plants. This 'OMF' project aims at developing methods and tools for analysis and in the first phase, applying these to one initial system (the pilot study). The results of the pilot study have confirmed the advantages of the 'OMF' analytical method: the prospects for the approach on an industrial scale are extremely promising. It should be noted that the precision of our 'OMF' analysis is not doubt superior to that common in other industrial domains (MSG/RCM analysis). The particular approach implies analysis of systems and components and, most importantly, integration of operation feedback, with a view to developing a rigorous maintenance program which can constantly be updated. In addition to the defining and implementing the method, the review of designing software aids has begun. The pilot study clearly pointed up the need for such aids in handling the necessary volume of information and assisting experts in their analysis. The EDF 'OMF' workstation (and its environment) will be used not only in preparing the 'initial' maintenance program but also in updating it during the 'living' program phase. (author)

  18. Pulverulent deposits on fuel assemblies in primary circuit on 2 units at EDF (France)

    International Nuclear Information System (INIS)

    Zatla, A.; Piana, O.

    2015-01-01

    In march 2013, during the moving of some fuel assemblies in the fuel deactivation pool of two units nuclear power plants (Blayais 4 and Chinon B2 units), some fine and powdery deposits in suspension have been observed. In the two cases, the fuel has stayed in the deactivation pool during a long time (12 and 3 months), the units have started for the first time to inject Zinc in the primary circuit in the beginning of the precedent fuel cycle, and the units have operated an extended fuel cycle. EDF has performed analysis to evaluate the harmfulness of the particles and to investigate the mechanisms involved in this phenomenon. 3 conclusions can be drawn. First, the deposits are made up of usual corrosion products issued from the primary circuit components. Secondly, the chemical composition and the powdery characteristics of the deposits exclude nuclear safety risks. Thirdly, the atypical behaviour of the deposits could probably be linked with a modification of their structure due to a zinc effect. Because of the lack of new understanding elements, the extension of zinc injection to other NPP units has been broken off currently in France. EDF is studying the international experience feedback to identify the operating parameters of the nuclear power plant which might influent the phenomenon, and to evaluate if the deposits could enhance fuel cladding corrosion

    2005-01-01

    This article describes the specificities of the operating principles chosen by EDF for the EPR project as a result of an extensive Human Factor Engineering program successfully implemented in an industrial project context. The design process and its achievements benefit of the EDF experience feedback not only in term of NPP operation - including the fully computerized control room of the N4-serie - but also in term of NPP designer. The elements exposed hereafter correspond to the basic design phase of EPR HMI which has been completed and successfully validated by the end of 2003. The article aims to remind the context of the project which basically consists in designing a modern and efficient HMI taking into account the operating needs while relying on proven and reliable technologies. The Human Factor Engineering program implemented merges these both aspects by : 1) being fully integrated within the project activities and scheduling; 2) efficiently taking into account the users needs as well as the feasibility constraints by relying on a multidisciplinary design team including HF specialists, I and C specialists, Process specialists and experienced operator representatives. The resulting design process makes a wide use of experience feedback and experienced operator knowledge to complete largely the existing standards for providing a fully useable and successful design method in an industrial context. The article underlines the design process highlights that largely contribute to the successful implementation of a Human Factor Engineering program for EPR. (authors)

  20. EDF experience with {open_quotes}hot spot{close_quotes} management

    Energy Technology Data Exchange (ETDEWEB)

    Guio, J.M. de [Blayais Nuclear Power Plant, St. Ciers (France)

    1995-03-01

    During the past few years, {open_quotes}hot spots{close_quotes} due to the presence of particles of metal activated during their migration through the reactor core, have been detected at several French pressurized water reactor (PWR) units. These {open_quotes}hot spots,{close_quotes} which generate very high dose rates (from about 10 Gy/h to 200 G/h) are a significant factor in increase occupational exposures during outrates. Of particular concern are the difficult cases which prolong outage duration and increase the volume of radiological waste. Confronted with this situation, Electricite de France (EDF) has set up a national research group, as part of its ALARA program, to establish procedures and techniques to avoid, detect, and eliminate of hot spots. In particular, specific processes have been developed to eliminate these hot spots which are most costly in terms of occupational exposure due to the need for reactor maintenance. This paper sets out the general approach adopted at EDF so far to cope with the problem of hot spots, illustrated by experience at Blayais 3 and 4.

  1. Alloy 600 head penetration cracking at EDF: Short and long term maintenance strategy

    International Nuclear Information System (INIS)

    Teissier, A.; Heuze, A.

    1995-01-01

    The discovering of a small leak on BUGEY 3 NPP Reactor Vessel Head (RHV) during 10 years hydrotest (end of 1991), was the beginning of an industrial challenge in terms of technical and economical aspects. Because of pressure vessel structural engineering and safety analyses, and overall, in-service inspection results on nearly 9/10 of the RVH in EDF plants (47), alloy 600 RVH penetration cracking is not a safety concern for the short term: only a few axial cracks (3%) on more than 3,200 penetrations inspected, and low probability to have an important circumferential crack on ID. Nevertheless, conservative measures have been taken for defense in depth: systematic first in-service inspection for diagnosis, repair criteria for deep crack, reliable and performance leak detection system on line, T cold conversion for 4 loops plants. For the long term, as the phenomenon is evolutionary, cracks have to be repaired. The definitive maintenance strategy is a purely economic choice. EDF decided to replace cracked RVH on a several years schedule and to fit periodic in-service inspection, in connection with crack risk initiation and propagation kinetic. (author)

    Background: Two studies, conducted in the eighties and the nineties, reported that mortality was lower- in the French national electric and gas company (EDF-GDF) the utility workers than in the general French Population. The purpose of our study was to compare the mortality of these 140.000 utility workers to that of the French population of the same age for the period from 1997 to 2001. Secondly we aimed to assess the disparities of mortality among the workforce according to demographic and socio-professional criteria. Finally, we analyzed the evolution of this mortality over the last twenty years. Methods: We undertook a cross-sectional study using the indirect standardization method. Results: Risk of death was lower in the utility workers than in the French Population (SMR=54% for men, and 58% for women). These differences had increased over the last twenty years for each main cause of death (cancers, cardio-vascular diseases and accidents). The reported excess of brain cancer death risk raises etiologic questions. Moreover; we noticed important social disparities in the workforce, increasing with tune. Conclusion: The well-known 'healthy worker effect' seems to be particularly important in the EDF-GDF company. The workers have a high level of living conditions and good working conditions, although internal social disparities persist. Further studies in other large corporations are greatly needed for comparisons. (author)

    In February 2008, a primary-to-secondary leak occurred at Fessenheim Unit No.2 on a steam generator. A circumferential fatigue crack was observed at the upper tube support plate level of the R12C62 tube although the stability ratio evaluation performed to take into account some prior international events, concluded that this tube had no risk of fluid-elastic instability. A new tube pull process was developed and performed by AREVA in 2011 just before the SG replacement. The extraction at the uppermost TSP elevation was a first occurrence in the French EDF PWR. Destructive examinations were carried out in the EDF hot laboratory of CEIDRE/Chinon in order to characterize damage mechanisms at the initiation and propagation stage. The document relates the major results of laboratory examinations leading us to exclude the fluid-elastic instability scenario as previously reported in North-Anna (1987) and Mihama (1991) tube rupture incidents. Results analysis with particular focus on the fracture surface description using Scanning Electron microscopy observations and metallurgical investigations provide new elements concerning the aggravating factors of fatigue damage. Fracture surface investigations reveal that the circumferential crack was due to high cycle fatigue with a very low stress intensity factor. Some aggravating factors like intergranular corrosion appeared to be critical for the fatigue cracking initiation stage. The deterioration was also largely promoted by the lack of tube support at the Anti-Vibration Bars

    A proper lay-up can only be achieved by plant specific lay-up procedures. The lay-up control practices are necessary to prevent corrosion damage during shut down and are an important part of the life extension of a nuclear power plant. EDF operational experience in this area confirms that damage to plant equipment from improper lay-up procedures is a cause of reduced plant reliability and availability and can increase the corrosion products ingress into the SG during start-up. This article presents the EDF lay-up program and the improvement of lay-up practices. It provides information on the lay-up procedures, best practices and recommendations, operating experience, considerations for different durations of outages; the implementation of a preservation working group, the selection of the systems that will be included in the lay-up program and the material damage characterization in some auxiliary systems. Finally, future developments will be presented, such as the development of a 'convective model' to determine air requirements (humidity, flow rate...) and the drying rate to dry a heat exchanger.

    1980-01-01

    The training of staff for the equipping, operating and servicing of EDF nuclear facilities was organized at a time when the undertaking had already developed its general training schemes and teaching methods. A brief account of these schemes and methods is given in the paper. Staff training at EDF was clearly devised with implicit regard for the educational and technological features of French society. This fact should not be forgotten when seeking to compare what is described here with developments abroad. The organization of training is based on a few relatively simple principles. The object of any training is to acquire competence, not just knowledge, and this calls for a combination of teaching and practical experience. Training programmes are drawn up taking into account the professional experience acquired in a particular trade, and training activities are, as far as possible, divorced from selection and examination procedures. The large number of workers needing to be trained in the nuclear field has led to standardization of training programmes. Teaching methods tend to be based on a combination of theoretical instruction and practical experience. Training thus involves the use of active or semi-active methods designed to promote familiarization with methods of working as well as the attainment of knowledge and ability. For these reasons, conditions of training as close as possible to actual work situations are created in the training centres, where great emphasis is placed on simulation techniques. (author)

  6. EDF decommissioning programme: A global commitment to safety, environment and cost efficiency of nuclear energy

    International Nuclear Information System (INIS)

    Chatry, Jean-Paul

    2002-01-01

    Nowadays, decommissioning of nuclear power plants has become a key issue for nuclear industry in Europe. The phasing out of nuclear energy in Germany, Belgium and Sweden, as well as the early closure of nuclear units in applicant countries in the frame of EU enlargement, has largely contributed to consider decommissioning as the next challenge to face. The situation is slightly different in France: nuclear energy is still considered as a safe, cost-effective and environment friendly energy source and EDF is still working on the development of a new generation of reactor to replace the existing one. Nevertheless, to achieve this objective, it will be necessary to get the support of political decision-makers and the acceptance of public opinion. The increasing mobilisation of EDF for the decommissioning of its already shutdown NPPs shows its willingness to demonstrate its capacity to control the nuclear life cycle from end to end. The successful implementation of its decommissioning programme will not mean the end of nuclear energy as an efficient way to generate electricity but it will constitute a prerequisite for the erection of new nuclear power plants in France

    This conference held on March 1997 presents the financial results obtained in 1996 by French Electricity Company EDF (Electricite de France). This year represented a turning point because essential landmarks were established in 1996. An european directive has been adopted in 1996 defining the framework in which european electricity market will function as well as the rules for its opening to competition. Discussions with the trade unions were conducted at the beginning of 1997 and a social agreement aiming at the amelioration of services and hiring of 11,000 to 15,000 young people in the next three years. Finally, a new contract of enterprise with the state has been discussed and approved in March 5, 1997, which redefined the place and the role of EDF in the French economy, in the new stage of electricity market started by the opening to competition. The document contains the following 8 chapters: 1. Financial results and enterprise management; 2. Institutional frame and the relation with the state; 3. Development in France; 4.

    After a period when several types of power reactors were operated, the most part of the French nuclear power plants were built in a 10 years time on the basis of a PWR design. This very important effort allowed France to face the oil crisis and an increase of power demand. Today nuclear energy keeps all its relevance in the French energy mix but a larger contribution of renewable energies is expected progressively. Light water reactors will stay dominant in the 2, 3 decades to come because of their important feedback experience and their economical competitiveness. The emergence of the 4. generation is not sure, it will depend strongly on: -) the available resources of uranium, -) the extend of the use of nuclear energy in the world, and -) its competitiveness compared to the 3. generation. This series of slides is divided into 3 parts: 1) the nuclear power in the French energy mix, 2) 3. generation reactors versus 4. generation ones, and 3) The EPR at Flamanville and in the world (China, Usa and Great-Britain).

    As part of the regulatory environmental monitoring around its nuclear power plants, EDF carries out every year more than 40.000 measurements. In addition EDF performs more precise radioecological surveys on all its sites. This monitoring shows the minor incidence of EDF's nuclear power plants on the environment and a general decrease of gamma emitters radionuclides in the environment. These results confirm the efforts lead by EDF to minimise its impacts on the environment, linked to an efficient waste management and demonstrate the good operating standards of its plants. On a qualitative viewpoint, significant efforts on both metrology and organization have lead to improved measurements capabilities, in order to achieve NF EN ISO/CEI 17025 standard compliance. More recently, a similar approach has been implemented with sampling methods. While today the level achieved in the number and quality of measurement complies with the objectives of the monitoring of the impact of the nuclear power plants on the environment, the results of this monitoring should be presented to the public with more pedagogy to give an adequate answer to their expectations. The new questions that will undoubtedly be raised by the recent availability of this information on the Internet should reinforce this dialogue and should also be the opportunity to improve the quality of our communication.

Durante décadas y hasta los años sesenta del siglo XX estas agriculturas andaluzas evolucionaron manteniendo el régimen contemporáneo de la economía terrateniente como producto de la combinación del sistema de pagos en trabajo o precapitalista y del capitalista. En los años sesenta se produce la crisis y readaptación de todos estos sistemas agrarios: sostendremos que desaparecen los regímenes de tenencia indirectos, pero se mantiene la gran propiedad latifundista mediante el control del poder político.

  19. EDF: Computing electron number probability distribution functions in real space from molecular wave functions

    2008-04-01

    Given an N-electron molecule and an exhaustive partition of the real space ( R) into m arbitrary regions Ω,Ω,…,Ω ( ⋃i=1mΩ=R), the edf program computes all the probabilities P(n,n,…,n) of having exactly n electrons in Ω, n electrons in Ω,…, and n electrons ( n+n+⋯+n=N) in Ω. Each Ω may correspond to a single basin (atomic domain) or several such basins (functional group). In the later case, each atomic domain must belong to a single Ω. The program can manage both single- and multi-determinant wave functions which are read in from an aimpac-like wave function description ( .wfn) file (T.A. Keith et al., The AIMPAC95 programs, http://www.chemistry.mcmaster.ca/aimpac, 1995). For multi-determinantal wave functions a generalization of the original .wfn file has been introduced. The new format is completely backwards compatible, adding to the previous structure a description of the configuration interaction (CI) coefficients and the determinants of correlated wave functions. Besides the .wfn file, edf only needs the overlap integrals over all the atomic domains between the molecular orbitals (MO). After the P(n,n,…,n) probabilities are computed, edf obtains from them several magnitudes relevant to chemical bonding theory, such as average electronic populations and localization/delocalization indices. Regarding spin, edf may be used in two ways: with or without a splitting of the P(n,n,…,n) probabilities into α and β spin components.

    It is shown that in the situation when the ambipolar field exceeds the heating field the local approximation (LA) for determining the EDF is not applicable even if the energy relaxation length of the electron is relatively small. Therefore, accurate results can be obtained only solving the kinetic equation in energy and spatial variables.

    Zinc's ability to replace cobalt from oxides of primary circuit surfaces has provided the first motivation for implementing the zinc addition in BWRs since the mid-1980s. The beneficial results regarding dose reductions have been demonstrated; therefore, this practice has been extended to PWRs since the 1990s, not only for radiation fields considerations, but also for reducing PWSCC. From the beginning of the 2000s, further reasons to inject zinc associated with the fuel management process have been identified (e; g; power increase, high burn-up, and/or cycle length increase). These evolutions must be accompanied by an adapted chemistry program in order to mitigate the crud deposition on fuel assemblies and the consequent AOA/CIPS or localized clad corrosion risks. The source term reduction (due to the decrease of the general corrosion rate of several materials) and the absence of negative impact on alloy cladding in the presence of zinc in the primary coolant are the main reasons for selecting zinc injection as a reliable option for preventing and/or mitigating the effects of fuel deposits. These three PWR motivations (field radiation, components performance, and fuel reliability) are also the major objectives of CANDU®, WWER, and new reactors (EPR, AP1000), where the zinc injection feasibility analyses are in progress in order to improve the safety of their operating conditions. With the purpose of achieving the optimal results of zinc injection, the process's implantation in a unit must be conducted with an appropriate risk analysis, covering all possible domains affected by this primary coolant chemistry modification : safety, fuel and component performance, radioprotection, waste, environment, human and installation security, human and material resources, staff formation, and documentation. EDF has performed a complete analysis of this enlarged scope, relying upon theoretical and experimental results as well as NPP feedback. This paper describes EDF

    1998-01-01

    To account for successive evolution of nuclear power plants emergency operation, EDF had several times to review PHRA methodologies. It was particularly the case when event-based procedures were left behind to the benefit of state-based procedures. A more recent updating was necessary to get pieces of information on the new unit type N4 safety. The extent of changes in operation for this unit type (especially the computerization of both the control room and the procedures) required to deeply rethink existing PHRA methods. It also seemed necessary to - more explicitly than in the past - base the design of methods on concepts evolved in human sciences. These are the main ambitions of the project named MERMOS that started in 1996. The design effort for a new PHRA method is carried out by a multidisciplinary team involving reliability engineers, psychologists and ergonomists. An independent expert is in charge of project review. The method, considered as the analysis tool dedicated to PHRA analysts, is one of the two outcomes of the project. The other one is the formalization of the design approach for the method, aimed at a good appropriation of the method by the analysts. EDF's specificity in the field of PHRA and more generally PSA is that the method is not used by the designers but by analysts. Keeping track of the approach is also meant to guarantee its transposition to other EDF unit types such as 900 or 1300 MW PWR. The PHRA method is based upon a model of emergency operation called 'SAD model'. The formalization effort of the design approach lead to clarify and justify it. The model describes and explains both functioning and dys-functioning of emergency operation in PSA scenarios. It combines a systemic approach and what is called distributed cognition in cognitive sciences. Collective aspects are considered as an important feature in explaining phenomena under study in operation dys-functioning. The PHRA method is to be operational early next year (1998

    1991-05-01

    In order to detect incipient failures in nuclear power plant components, EDF has now put into operation more than 50 loose-part monitoring systems, on its 900 MW and 1 300 MW units. This paper first reviews the experience gained on the 900 MW reactors in recent years. It then focuses on the 1 300 MW loose part monitoring system (IDEAL) and to the tools developed for the diagnosis off site within a specific Expertise Laboratory at the Research and Development Division. New studies have been undertaken within the Monitoring and Aid to Diagnosis Station (PSAD) in order to extend the capabilities of loose part diagnosis on site. The new tools here presented integrate the recent progress in acquisition technology (SMART system) and in artificial intelligence (MIGRE expert system)

    2007-11-01

    This thesis tries to answer the practical and theoretical problems of environment protection in the case of the hydropower branch of Electricite de France (EDF) company. These problems concern the contribution of the company to environment protection and the evaluation of this contribution. The work stresses on the synergic dimension (cooperation and negotiation) of the company/environment problem but also on the conflict dimension necessarily associated to this problem. The environmental management of a company has to deal with the complex game between the internal organisational stakes and the external relational strategies. A model is proposed which allows to evaluate the efficiency of a given environmental management system and to evaluate the participation of companies to this system with respect to the above listed points. Finally, some recommendations and elements of answers are proposed. (J.S.)

    In January 2014, the ASN (French Authority for Nuclear Safety) published a list of 19 decisions concerning the implementation of a 'post-Fukushima' hard-core unit in each EDF nuclear power plant. The purpose of the hard-core unit is to have structures and equipment able to resist very extreme events and able to assure the vital functions necessary for the reactor safety. The 19 decisions detail the rules for the design of the hard-core unit. For example the hard-core unit will have to resist earthquakes for which the probability of occurrence is about 1 every 20.000 years while the probability taking into account for the design of the reactor is only 1 every 1000 or 10.000 years

    Having first evoked the problems arising from the definition of a so-called 'acceptable risk', the probabilistic study programme on safety carried out at the E.D.F. is described. The different aspects of the probabilistic estimation of a hazard are presented as well as the different steps i.e. collecting the information, carrying out a quantitative and qualitative analysis, which characterize the probabilistic study of safety problems. The problem of data determination is considered on reliability of the equipment, noting as a conclusion, that in spite of the lack of accuracy of the present data, the probabilistic methods already appear as a highly valuable tool favouring an homogenous and coherent approach of nuclear plant safety [fr

    The world is changing. Environment and Health are key issues, especially in western countries. People start to worry about the impact of the products they use or eat and about their legacy to their children, on a worldwide scale : 'We do not inherit the earth from our parents; we borrow it from our children' is one of the current new motto for the c itizens of Earth . In such a context, nuclear energy is less accepted than before. The recent debate over the ozone layer, global warming and climate change, GMOs, mad-cow disease and most recently uranium-based ammunitions, cannot but reinforce the deep mistrust felt by large components of the society. Opponents to nuclear energy have found a new audience, and some political decisions take this evolution into account. This mistrust is reinforced by the absence of a direct link between EDF and the general public. However: a new attitude is emerging, which might be an opportunity for us. Citizens demand the right to know, the right to shape their own point of view, using first-hand information. Internet is an obvious answer to this need for more personal, human contact. This presentation discusses how do you establish a link with people browsing the net, so they can shape their own opinion about nuclear energy? A climate of trust is key, based on the following ingredients: Transparency; Responsibility and trustworthiness; Openness and Empathy; Innovation; Interactivity. An overview on 8 months activity is displayed. The EDF web site has improved since its launch and is still improving today. It is not considered a finished product

    Nowadays, zinc injection, as well as pH management and hydrogen control, is increasingly considered as an essential element of PWR Primary Water Chemistry worldwide. After a first implementation of zinc injection at Bugey 2 since 2004 and Bugey 4 since 2006, EDF decided to extend this practice, which constitutes a modification of primary circuit chemical conditioning, to other units of its fleet. Currently, 15 among the 58 reactors of the French fleet are injecting depleted zinc acetate into the primary coolant water. Three main goals were identified at the beginning of this program. Indeed, the expected benefits of zinc injection were: Reduction of the rate of generalized corrosion and mitigation of stress corrosion cracking initiation on nickel based alloys (Material goal). Curative or preventive reduction of radiation sources to which workers are exposed (Radiation fields' goal). Mitigation of the AOA or CIPS risks by reduction of corrosion products releases and mitigation of crud deposition (Fuel protection goal). To monitor the zinc addition, EDF has defined a complete survey program concerning: chemistry and radiochemistry responses (primary coolant monitoring of corrosion and fission products and calculation of zinc injected, zinc removed and zinc incorporated in RCS surfaces) ; radiation fields (dose rates and deposited activities measurements) ; materials (statistical analysis of SG tube cracks) ; fuel (oxide thickness measurements and visual exams) ; effluents (corrosion products releases and isotopic distribution follow up) ; wastes (radiochemical characterization of filters). This paper will detail the present results of this monitoring program. It appears that the expected benefits of zinc injection have yet to be fully realized; further operating experience will be required in order to fully evaluate its impact. (author)

    2017-01-01

    About 17.000 tons of irradiated graphite waste will be produced from the decommissioning of the six gas-cooled nuclear reactors operated by Electricite De France (EDF) company. Determining the radionuclide content of this waste is an important legal commitment for both safety reasons and best suited management strategy. As evidenced by numerous studies nuclear graphite is a very complex material that cannot be considered on an analytical viewpoint as any usual homogeneous material. Radionuclide measurements in irradiated graphite exhibit very high discrepancies especially when corresponding to precursors at trace level. This huge discrepancy cannot be avoided and can be easily explained by Pierre Gy's theory of sampling applied to finely divided materials. The assessment of a radionuclide inventory only based on a few number of radiochemical measurements leads in most cases to a gross over- or under-estimation that can be detrimental to graphite waste management. Prior to 2005, the EDF initial version for the radiological inventory of graphite was based on the maximum values of the measures, namely a very pessimistic way. In 2008, a scientific method was developed by EDF to evaluate the inventory by reverse activation calculation, in order to limit the overestimation. The radiological inventory computation principles can be compared to those of all engineering studies. First, the calculation is simplified by taking margins, and if the results are not satisfactory enough, some simplifications are suppressed to reduce these margins even if computation becomes more complicated. On EDF piles, the gain obtained in 2008 represented a factor 50 relative to the initial version of 36 Cl, even with a very penalizing multiplicative factor for uncertainty. Today, the accurate calculation of the uncertainty no longer justifies such a factor. A gain of about 150 now occurs compared to the initial version of 36 Cl. It is more than 2 orders of magnitude, which is already

    EDF is the world's leading nuclear operator with 74.8 GW of installed capacity in France, the United Kingdom and the United States, an EPR under construction in France, and 2 EPRs under construction in China through TNPJVC (EDF 30%), a joint venture with CGNPC. As such, EDF acts at all stages in the life of its power plants (design, construction, operation, decommissioning) to: - ensure rigorous operation of facilities; - prevent all incidents and accidents; - reduce the impact of any incidents or accidents that might nevertheless occur. The main safety measures were published in a single document in 2015 setting out the Group's nuclear safety policy. Each nuclear operating company inside the Group acts in compliance with the legal obligations and regulations specific to its host country. Each company works to ensure and continuously improve its safety performance with its own methods, skills and values. The EDF Group respects national differences. At the same time it frames common principles to deliver the highest level of incident prevention and protection of the public, workers and the environment. This policy applies to new projects (overall architecture, design and construction) and all existing plants (operation, maintenance, waste management, decommissioning and engineering). The Group works closely with its industrial partners to deliver these objectives. Each company is responsible for the proper operation of its nuclear activities, and delegates responsibilities appropriately to each level of management or operation. The Group guarantees the allocation of resources needed to ensure nuclear safety. An in-house independent nuclear safety function is in place at power plant level, company level and Group level. Each has a duty to alert senior management of inappropriate or inadequate line management response. Nuclear safety is the absolute priority for the EDF Group at every stage of the plant life-cycle. Each company is responsible for ensuring

    Can-rupture detection (DRG) is one important aspect of pile safety, more particularly so in the case of gas-cooled reactors. A rapid and sure detection constitutes also an improvement as far as the efficiency of electricity-producing nuclear power stations are concerned. Among the numerous can-rupture detection methods, that based on the measurement of the concentration of short-lived fission gases in the heat-carrying fluid has proved to be the most sensitive and the most rapid. A systematic study of detectors based on the electrostatic collection of the daughter products of fission gases has been undertaken with a view to equip the reactors EL 2, G 3, EDF 1, EDF 2 and EDF 3, the gas loops of PEGASE and EL 4. The different parameters are studied in detail in order to obtain a maximum sensitivity and to make it possible to construct detection devices having the maximum operational reliability and requiring the minimum maintenance. The primary applications of these devices are examined in the case of the above-mentioned reactors. (author) [French] La Detection des Ruptures de Gaines (D. R.

    From the very beginning of France's nuclear power programme, EDF has developed industrial-scale management of the waste it produces, which has constantly progressed in line with changes in the regulations and the available technology. This management process, improved thanks to feedback and experience, ensures that any risk of exposure, at every stage, from production to final disposal, is controlled. The guidelines adopted by EDF for sustainable management of its waste are as follows: reduce the quantity of waste, from the production stage and then through recycling and reprocessing; sort waste according to its nature and activity level, so that it can be processed and packaged appropriately and the appropriate long-term management solution implemented; package waste as soon as it is produced to prevent any risk of dispersion; store waste, pending decay or the availability of an appropriate disposal solution; transport and place waste in repositories, keeping it away from Man and the environment by means of engineered or natural barriers for as long as required for the radioactivity to decay to an acceptable level. Regarding short-lived waste produced during operating and maintenance activities at power plants in service, EDF currently implements fully-integrated industrial management solutions which are constantly being optimised in conjunction with its industrial partners.

    This decision from the French authority of nuclear safety (ASN) concerns the conditions of storage of very-low level radioactive wastes in EdF nuclear power plants. These wastes, sometimes stored in important quantity, can lead to three type of risks: fire hazard, dispersion of radioactive particulates, and radioactive pollution of soils and aquifers. In front of this situation, the ASN has imposed to EdF to implement the following actions: an inventory of the stored wastes and a risk analysis of the present day storage conditions (before February 2001), a respect of the basic rules of storage management (access, ground protection, fire prevention, before March 2001), and the storage of these wastes in proper sites and facilities within 4 years.

    Full Text Available Depuis 1953, de nombreux chercheurs se sont intéressés à la datation par thermoluminescence de minéraux anciennement brûlés ou cuits. Dans ce travail, après avoir rappelé quelques principes physiques de la thermoluminescence, on présente cette méthode de datation en mettant l'accent sur le mécanisme thermoluminescent dans une poterie. Ainsi la dose d'irradiation reçue par le matériau étant proportionnelle au temps écoulé depuis le 'zéro archéologique', il est possible de déterminer 'la dose archéologique' et d'en déduire l'âge de l'échantillon après avoir calculé la dose d'irradiation annuelle. La réalisation pratique d'un tel ensemble de mesure est cependant très ardue. Dans un prochain article, E. A. Decamps et A. Roman montreront des résultats relatifs à la thermoluminescence d'échantillons de quartz naturels, purs et dopés et la mise au point d'une nouvelle méthode de datation.

    This presentation describes the fifteen advanced instructors station and four simulated control delivered to EDF in the frame of the SIROCCO project by the Consortium formed by ATOS Origin, CORYS Tess, for the Electricite de France (EDF). These instructor stations are installed on fifteen replica training simulators located on different sites throughout France for the purposes of improving the job-related training of the EDF PWR nuclear power plant operating teams. This covers all 900 MW and 1300MW nuclear power plant of EDF. The simulated control rooms are installed on maintenance platform located at EDF and the consortium facilities. The consortium uses it to maintain and upgrade the simulators. EDF uses it to validate the upgrade delivered by the consortium before on site installation and to perform engineering analysis. This presentation sets out successively: - The major advantages of the generic and configurable connected module concept for flexible and quick adaptation to different simulators; - The innovative functionalities of the advanced Instructor Desk (IS) which make the instructor's tasks of preparation, monitoring and postanalysis of a training session easier and more homogeneous; - The use of the Simulated Control Room (SCR) for training purposes but also for those of maintenance and design studies for upgrades of existing control rooms

    2012-09-01

    EDF has developed during these 15 last years software called BRT-CICERO TM for the surveillance of the secondary piping system of its Pressurized Water Reactors (PWRs). This software enables the operator to calculate the FAC wear rates taking into account all the influencing parameters such as: pipe isometrics, chromium content of the steel, chemical conditioning and operating parameters of the secondary circuit (temperature, pressure, etc.). This is a major tool for the operators to organize the maintenance and to plan the inspections. In the framework of the French pressure vessel law issued on March 15, 2000, the software BRT-CICERO TM has been recognized by the French authority for the FAC surveillance on the secondary pressure piping lines of the EDF 58 NPPs. It takes advantage of the experience feedback of the French fleet, of the R and D improvements (especially from the laboratory tests conducted on EDF's CIROCO loop) and is frequently updated. The software is based on specific calculation modules, which are: - thermodynamics module, - chemistry module, - void module, - geometric factor module to take into account the effect of singularities on hydraulics, - FAC kinetics module, - codes and standards module for minimum required thickness calculations. This architecture allows independent and complete validation of each model calculation and therefore the quality of software. This paper describes the simplified model and the calculation modules. The performances of BRT-CICERO TM version 3 are examined with a statistical analysis allowing estimating the accuracy of calculation for each components and position into the pipelines. A computational fluid dynamic study has been initiated to confirm the geometrical coefficients which allow to take into account the fittings. All these studies and many others brought EDF to propose evolutions both on the plan thermodynamics and chemical. These evolutions are discussed in this topic. (authors)

  5. EDF decommissioning and dismantling policy a global commitment to safety, environment and cost efficiency of nuclear energy

    Rondeau, J.

    2001-01-01

    Until recently, EDF's policy regarding the dismantling of its decommissioned nuclear power plants was to reach 'level 2' (release of non-nuclear facilities) and to postpone final dismantling for another 30-40 years. Today, some studies suggest that a full deconstruction program of the first generation NPPs (9 units) could be optimized over the period 2000 - 2025. EDF has acquired during the last ten years an unique experience, both as an operator and as an engineering company, in the frame of the decommissioning programme of its own NPPs. Many types of reactors, including graphite moderated one, PWR, are at varying stages of the dismantling process.Plant operation quality is at the core of a satisfactory control of releases. Over the last decade, as a result of the efforts of all operating sites associated with good in-house operating practice feedback, the overall release volume has been divided by two, and the release activity by one hundred. Another issue given increased attention is radiological cleanliness. EDF-DPN launched a 'radiological cleanliness' action plan revolving around two main themes: increased monitoring of nuclear-related transportations, site entrance and access to controlled areas, along with on-site radiological cleanliness, particularly during maintenance work tasks. Progress is already apparent in several points at issue and the overall objective of the action plan should be attained. (author)

  7. Bayesian estimation of covariance matrices: Application to market risk management at EDF

    International Nuclear Information System (INIS)

    Jandrzejewski-Bouriga, M.

    2012-01-01

    In this thesis, we develop new methods of regularized covariance matrix estimation, under the Bayesian setting. The regularization methodology employed is first related to shrinkage. We investigate a new Bayesian modeling of covariance matrix, based on hierarchical inverse-Wishart distribution, and then derive different estimators under standard loss functions. Comparisons between shrunk and empirical estimators are performed in terms of frequentist performance under different losses. It allows us to highlight the critical importance of the definition of cost function and show the persistent effect of the shrinkage-type prior on inference. In a second time, we consider the problem of covariance matrix estimation in Gaussian graphical models. If the issue is well treated for the decomposable case, it is not the case if you also consider non-decomposable graphs. We then describe a Bayesian and operational methodology to carry out the estimation of covariance matrix of Gaussian graphical models, decomposable or not. This procedure is based on a new and objective method of graphical-model selection, combined with a constrained and regularized estimation of the covariance matrix of the model chosen. The procedures studied effectively manage missing data. These estimation techniques were applied to calculate the covariance matrices involved in the market risk management for portfolios of EDF (Electricity of France), in particular for problems of calculating Value-at-Risk or in Asset Liability Management.

    The internal organisation for first aid to the injured in case of an accident on E.D.F. nuclear power plant calls for the immediate assistance of a first aid team, consisting of five workers, under the direction of a principal first aid officer; one of the first aid workers, the sanitary officer who instructs the first aid workers intervention awaiting the arrival of an external medical. When the 'Sanitary on-site Emergency Plan' was up' dated, twenty medical doctors and seventy members of staff from five different sites were questioned as to the function of the sanitary officer. The conclusions revealed a notable difference of training amongst the different sites, and concerning first aid organisation, difference of priority of actions, extent of their participation once the medical team arrives and their participation in case of decontamination treatment. The medical doctors and staff lay a particular stress on importance of defining on a national scale the limits of role and responsibilities of the sanitary officer and establish a more specific training in this field, consequently motivating commitment and professionalism involvement. There is a great difference between the training and coaching of the first aid assistance and fire protection teams. To conclude, we propose that the first aid officer be known as first aid coordinator and the qualification of 'Certificat de Formation aux Premiers Secours en Equipe' in compliance with the current legislation together with a specific nuclear module and they should undergo regular on-site drills.

    Bousrih, M.

    2007-05-01

    The electric power industry is witnessing significant transformations dealing with the principles of the market organization. The reforms of the sector regulations modify the functioning rules, and in reply, the firms adapt their strategic behaviour through partner policies and alliances. Since 1996, several alliances cases have emerged. The present research work consists in the examination of motivations that are the origin of these partnerships inciting the big power companies to set off on a race to external growth. The first part of the thesis tackles the reconfiguration of the power industry in Europe and clarifies the different motivations of companies that decide to form an alliance (to get into a new market, pass the over capacities, search considerable effect engendering important economies and synergies, base an effect power and a safety motivation). The second part focuses on the study of EdF and Enbw links through the analysis of synergies brought out by such alliance and the construction of possible progress scenarios for this alliance (starting from the analysis of strategic intentions of both Allies, a scenario of success or break down is built up).

  10. EDF and local authorities: a historical model of compromise and control?

    2008-01-01

    The June 15, 1906 Distribution Act is central to the country's legal and energy heritage, and has retained, after 1946, its validity and relevance, in the era of EDF. By acknowledging the essential role of local authorities, mainly cities, it established the local public electricity agency (SPL) based on relationships between the licensor and the Licence Holder. After setting up the FNCCR (Federation Nationale des Collectivites Concedantes et Regies) in 1933, the April 8, 946 Nationalization Act had initiated a golden age for local electric economy control by public agencies, by confirming the privileges of local authorities. The end of rural electrification, the role of FACE (Fonds d'Amortissement des charges d'electrification rurale) and the increasing number of inter-city associations symbolize the French model of concession economy. Open competition under European energy liberalization directives since 1990 has led to increased authority, as well as responsibilities, for local authorities looking for a new SPL. Its key words are not only competitiveness, but also social and territorial solidarity and the new requirements of sustainable energy development, and its agenda. (author)

  11. EDF training process: From the training needs to the training requirements

    2002-01-01

    The Training and Development Division - SFP - is the main EDF actor in the strategic skills development. It is the prime contractor designated by the Nuclear Generation Division DPN. The four main SFP goals for the period 2001/2003 are as followed: to satisfy our customers, to optimize and diversify our offer in reply to the needs of our customers and to adapt our skills, to improve our efficiency (cost-effectiveness ratio), and to reinforce the Quality Management of the SFP. The SFP has a quality policy ISO 9001 oriented. It is based on 6 commitments: to take into account the needs of each client regarding training, to insure the requirements of the quality approaches followed by our clients, to assist the national specifications in the training area, to inform SFP customers about the whole training offer, to give a first answer 8 days after each complaint, to provide trainees a good and adapted learning environment. A customers satisfaction survey twice a year and frequent internal and external audits and assessments guarantee these commitments.The main challenge for the Nuclear Generation Division - DPN - is to improve the performances in safety and competitiveness and to increase the professionalism of people involved. That is the reason why the partnership between the DPN and the SFP is now based on the skills management instead of the courses organisation

  12. The rationale for improving EDF chemistry plan for the next years

    2012-09-01

    Although the chemistry of PWR NPPs seems to reach more and more the best practices to keep the NPPs safe, it can be noted that different strategic approaches could be adopted depending on the operation events, the strategy of companies for the future and external constraints such as environmental rules to comply with. This paper describes different improvements leading to optimize the chemistry of the French NPPs. Those improvements result from: - the operation modifications and data coming from new tools to survey the operation process; - the need to intensify the surveillance to anticipate events like SG clogging; - the need to take into account the material ageing and a longer life duration up to 60 years; - the need to adapt the strategy for the waste treatment to comply with environmental rules... All these considerations lead EDF to review: - the way to elaborate the chemistry guidelines differently to be able to improve the surveillance; - the implication of chemistry on deviation of physical parameters like the flow rate; - what is relevant with the long life duration taking into account the planned replacements of materials and their ageing; - the combined strategies of several chemistry levers to manage phenomena like stress corrosion cracking or mass transport; - what is needed to implement or even anticipate because of new environmental constraints.

    Uniform corrosion of fuel cladding could be a limitation for burn-up enhancement. First, the oxide thickness measured on fuel cladding for high burn-up has been compared to the prediction of the EDF code, CYRANO 2E. A comparative metallurgical characterization has been also performed on samples which were oxidized in pile and in autoclave. Then, laboratories studies have been launched for a better understanding of the corrosion mechanisms. A reflection was proposed on the two main theoretical concepts proposed for these mechanisms. Their kinetics could be controlled by transfers in liquid medium (electrolyte) or in solid medium (compact oxide). For the first topic, a nanoscopic characterization of the oxide is in progress, using Atomic Force Microscope. The first results are presented. In the second case, an electrochemical approach (impedance spectroscopy and voltametry) is developed in our laboratories. The obtained results could give some new keys in order to understand the influence of some parameters (alloys composition, coolant chemistry,...). (authors). 7 figs., 1 tab., 7 refs

  14. EDF, the market and Europe. The future of a public utility

    International Nuclear Information System (INIS)

    Fitoussi, J.P.

    2003-01-01

    European governments have decided, in the framework of the unique market, to open their national market to competition. Electricite de France (EdF), like the overall French public utilities, has to adapt to this new situation. The question is: how to perform this mutation and avoid ultra-liberalism? This is the main guideline of this book which aim is to define the modalities of the necessary implication of the government and the ones of a new kind of company governance in a sector where regulation errors can have dramatic consequences (like the power outage in the US). The objective of the author is not to propose a simple compromise between market and public utility logics, but to consider the double opening of markets and companies capital as new opportunities to improve both the public utility and the companies efficiency. Such a company 'of the third kind' (somewhere between governmental and private) can be built only if the new rules and reforms are made in a clever and profitable way, i.e. in compliance with sustainable development principles, in the respect of management transparency, and for the benefit of general people and in particular the end-users.

    Full Text Available El artículo analiza la historia local a partir de la sociología de regímenes propuesta por Fred Spier y clasificada por Norbert Elias. El texto analiza los aspectos políticos, ambientales y personales en ámbitos locales. El autor expone la funcionalidad explicativa y analítica del concepto, y lo instrumentaliza en el caso de la fundación y el ámbito social de San Juan Girón (Santander, Colombia en el siglo XVII. La fundación es vista como el establecimiento de un régimen político cuyas figuras y entidades activas las representa el gobernador y el Cabildo de la ciudad en el marco de una serie de conflictos jurisdiccionales con los habitantes nativos y de localidades vecinas. El efecto de la fundación estimula un proceso de colonización en un paisaje geográfico que determina el régimen ambiental en el que se destacan colonos, hacendados, agricultores y ganaderos. Finalmente el régimen individual se traduce en la creación de redes de parentesco, que reflejan diferenciaciones y rivalidades sociales y étnicas entre grupos y personajes distinguidos de la localidad. El autor se apoya en fuentes primarias y secundarias para rendir cuenta del proceso político-administrativo de la fundación y la emergencia de personajes que constituyeron la red socio-administrativa y gestora del hecho histórico.

  19. PWR circuit contamination assessment tool. Use of OSCAR code for engineering studies at EDF

    Directory of Open Access Journals (Sweden)

    Benfarah Moez

    2016-01-01

    Full Text Available Normal operation of PWR generates corrosion and wear products in the primary circuit which are activated in the core and constitute the major source of the radiation field. In addition, cases of fuel failure and alpha emitter dissemination in the coolant system could represent a significant radiological risk. Radiation field and alpha risks are the main constraints to carry out maintenance and to handle effluents. To minimize these risks and constraints, it is essential to understand the behavior of corrosion products and actinides and to carry out the appropriate measurements in PWR circuits and loop experiments. As a matter of fact, it is more than necessary to develop and use a reactor contamination assessment code in order to take into account the chemical and physical mechanisms in different situations in operating reactors or at design stage. OSCAR code has actually been developed and used for this aim. It is presented in this paper, as well as its use in the engineering studies at EDF. To begin with, the code structure is described, including the physical, chemical and transport phenomena considered for the simulation of the mechanisms regarding PWR contamination. Then, the use of OSCAR is illustrated with two examples from our engineering studies. The first example of OSCAR engineering studies is linked to the behavior of the activated corrosion products. The selected example carefully explores the impact of the restart conditions following a reactor mid-cycle shutdown on circuit contamination. The second example of OSCAR use concerns fission products and disseminated fissile material behavior in the primary coolant. This example is a parametric study of the correlation between the quantity of disseminated fuel and the variation of Iodine 134 in the primary coolant.

  20. CATHARE Approach Recommended by EDF/SEPTEN for Training (or other) Simulators

    International Nuclear Information System (INIS)

    Pentori, B.; Iffeneckeft, F.; Poizat, F.

    1999-01-01

    This paper describes EDF's approach to NSSS thermal-hydraulics - this is the crucial module in a real-time simulator (this constraint relaxes requirements in respect of neutronics) because it determines the simulator's scope of application. The approach has involved several stages: (1) Existing full-scalers (1980-85 design), equipped with a five-equation primary model (about 40 nodes), coupled with a three-equation axial model of the SG secondary side (plus a very simple model for refilling/venting and draining), which can simulate only a small, 2-inch LOCA and up to 15 bar primary-system pressure; (2) SIPA(CT) and the new full-scalers at Fessenheim and Bugey (1990-95 design). These tools feature Cathare-Simu, an outgrowth of CATHARE 1 (six primary-system equations, four secondary-side equations, at least 187 nodes - extended to the steam header, implicit digital processing, possible parallelisation): this model permits simulation of breaks of up to 12 inches and at very low primary-system pressure; (3) SCAR (1995-2000 design) will be adapted from the CATHARE 2 design code (six equations everywhere, non condensables, 2D and 3D modules), and will allow simulator processing of all operating conditions (except for a severe accident, in the strict sense of core melt), including scenarios based on 481 broken primary piping, at atmospheric pressure. Only the fine-modelling capabilities of CATHARE make it possible to add genuine echographies to the traditional Man Machine Interface. (author)

    Like other electricity utilities, Electricite de France seeks to enhance the safety and availability of its nuclear power plants. To this end, for over ten years EDF has been installing on each plant unit two monitoring systems of its own design, one to monitor the primary cooling system, and the other, the turbogenerator set. Since the beginning of this project, widespread progress has been made in techniques of signal acquisition and processing, and in diagnosis using artificial intelligence methods. EDF has decided to call on these advanced techniques in developing its new-generation monitoring equipment, and to integrate them in its development of a workstation for on-line monitoring and diagnosis-support (PSAD: Poste de Surveillance et d'Aide au Diagnostic). PSAD will be a tool for on-line monitoring of the main components in nuclear power plants (initially the main coolant pumps and turbogenerator sets, and soon thereafter, monitoring of internal structures, detection of loose parts in the primary cooling system, etc.). PSAD will provide plant personnel with indispensable support in their diagnosis of the condition of plant equipment. It will integrate user-friendly, high-performance systems that also free the operator from many day-to-day tasks. PSAD will have a flexible architecture, for optimum distribution of the computing power where it is most needed, thereby improving the quality of the data. This paper presents the project objectives and describes work currently under way to implement EDF's diagnosis-support strategy for the years to come. (authors). 5 figs., 6 refs

    As neutron irradiation of nuclear reactor structure steel results in changes in physical and mechanical properties, notably an increase of the ductile-to-brittle transition temperature and of yield strength, and as a previous report addressed the study of the relationship between the increase of transition temperature and Wigner doses for some French alloys irradiated within EDF 1 and G1 graphite reactor cores, this report is a complement to this previous study. By using the same correlation method, the author studied the relationship between variations of yield strength and damage flows, as well as the interdependence with transition temperature [fr

    A first document proposes a synthesis of an assessment performed by the IRSN which more particularly addressed how the client (EDF) takes up nuclear safety challenges, and its ability to transmit them to the subcontractor and assess the way he takes them up, how the subcontractor adopts these safety issues and translate them into an adapted technical action, the efficiency of information transmission from the subcontractor to the operator, and the way EDF takes the evolution and increase of activities into account in its subcontracting management strategy on the medium and long terms in relationship with modifications generated by recent measures (additional safety assessments, project of lifetime extension). Another document states the opinion of the permanent group of experts for nuclear reactors on these issues, and outlines some specific aspects (unit outage and maintenance planning, risk analysis, intervention preparation and monitoring, return on experience and improvement of the management of subcontracted activities, evolution and increase of activities). Some recommendations are also stated. A third document is a letter sent by the ASN on the same issues which discusses problems and issues related to subcontracting and has been the basis of the IRSN assessment

    Electromagnetic fields are suspected of many health effects, including cancers, immunity and fertility disorders, congenital malformations, suicides and depression.... Although the results of all studies are contradictory and no biological mechanism has been found, populations are concerned about this matter. This study analyzes the absence from work of some EDF employees who are a priori the most professionally exposed to ELF EMF. Absence from work is taken as an health indicator. Although it is not specific, it can be predictive of serious health problems. The specific context of EDF has made it possible to collect and analyze the medical aspect of absence from work, that is rare in France. We were interested with employees working with high voltage (over 90 kV). Three job categories have been selected: live line workers, substation maintenance workers and substation exploitation workers (called in the company the ATEX). The first group concerned the live linemen and the results were exposed previously. It appeared they had more accidents at work, but this was more related to the job of lineman rather than to the EMF exposure. Nevertheless, substation workers have an exposure less intensive but longer than live linemen. We present here the result about the absenteeism of the substation workers, maintenance and exploitation. (author)

    The French nuclear power program was pushed through in order to reduce the country's dependence on imported fossil sources of energy. Nuclear power and hydro power have achieved a level of self-sufficiency in the energy sector of more than 50%. It should be emphasized that the French nuclear power program was largely self-financed. Electricite de France (EdF) considers itself well prepared for the European market, provided the creation of the single market implies that electricity rates are taken as a yardstick of competitiveness. Negotiations about a European directive on deregulating the electricity market were for the government to hold. EdF pleaded in favor of preserving for each country a certain leeway for shaping its own policy. The road to deregulation was to be opened, but the specific situation of each country was to be taken electricity to be passed through imposes narrow constraints upon an expansion of exchanges of electricity, and public acceptance is not very likely to be achieved for the construction of new international high voltage transmission lines.

    Full Text Available Los nuevos modelos de regímenes de pensiones implantados a finales del siglo XX están siendo objeto de revisión, en todos sus elementos fundamen-tales, con el objetivo de detectar las deficiencias más significativas de su di-námica. Uno de los elementos que ha sido considerado para su reforma es la estructura de las comisiones que deben satisfacer los afiliados al régimen de ahorro individual a las administradoras de fondos de pensiones de su elec-ción. La valoración de la modalidad de comisión más eficiente en relación con los objetivos del sistema de pensiones, fundamentalmente la generación de pensiones de cuantía suficiente y adecuada, así como la expansión de su cobertura, se realiza a partir del análisis de las principales reformas que en esta materia han acometido los regímenes de pensiones del área latinoameri-cana. De entre las categorías de comisión, la basada en el salario del trabaja-dor presenta ventajas sobre el resto de modalidades en orden a la contención de gastos de las administradoras de fondos de pensiones y la cobertura del sistema de seguridad social.

    2016-01-01

    Superphenix is a 1200 MWe sodium cooled Fast Breeder Reactor (FBR) located in Creys-Malville (France). Its grid coupling occurred in 1986 and its final shutdown pronounced through a decree, 12 years later, in 1998. This Superphenix final shutdown decision marked a new stage in the life of the nuclear plant. Decommissioning activities were highly challenging due to the following: - Non recurrent and first-of-a-kind (FOAK) characteristics; - Environment constraints: radiation level, high temperatures, presence of argon, sodium, NaK, soda, hydrogen, etc.; - Complexity of the primary vessel internal structures; - Numerous interfaces to manage; - Numerous technical uncertainties due to the difficulty in anticipating the effective state of components (sodium and aerosols retentions, tritium concentration, NaK alteration, etc.). At the end of 1998, exchanges took place between EDF as 'Superphenix nuclear operator' and AREVA as 'Superphenix Nuclear Steam System Supply (NSSS) designer' in order to find the best way to meet the new challenge of decommissioning Superphenix. A key ingredient to achieving success was to ensure that existing local and specific sodium skills were controlled and maintained. AREVA was selected by EDF as its industrial partner for the sodium activities on this project being entrusted with the following missions: - Maintaining and adapting a strong EDF / AREVA partnership within the project duration; - Supplying support as the 'NSSS Designer'; - Rolling-out multidisciplinary skills from the design to the on-site operations; - Relying on its best technical experts to solve each technical challenge; - Developing and adapting durable specific skills of its technical team (sodium, mechanical, process, I and C, statutory, etc.) following each stage of the decommissioning. This EDF/AREVA partnership on the sodium activities has taken different forms according to the different stages of the project. From 1998 to 2005, AREVA was

    1969-10-01

    The authors report the verification of the Zeus 4 Monte Carlo code by applying it to an actual example of neutron propagation in a large enclosure, the empty mesh of the EDF3 reactor, supplied through the box holes (for the passage of heat transfer fluid ducts). This enclosure is represented by 105 parallelepipedic meshes in which are placed 4 plane and square sources of same cross section as the holes, and emitting inwards in cos θ. Source intensity is determined by flow rate measurements during tests in the air, interpreted by a Zeus-based calculation and channel power measurements during a 387 MW level operation. The presence of ducts is taken into account by applying a global attenuation coefficient to the sources. Calculation and experiment results agree very well in view of geometry complexity [fr

    MenE, the o-succinylbenzoate (OSB)-CoA synthetase from bacterial menaquinone biosynthesis, is a promising new antibacterial target. Sulfonyladenosine analogues of the cognate reaction intermediate, OSB-AMP, have been developed as inhibitors of the MenE enzymes from Mycobacterium tuberculosis (mtMenE), Staphylococcus aureus (saMenE) and Escherichia coli (ecMenE). Both a free carboxylate and a ketone moiety on the OSB side chain are required for potent inhibitory activity. OSB-AMS (4) is a competitive inhibitor of mtMenE with respect to ATP (K{sub i} = 5.4 {+-} 0.1 nM) and a noncompetitive inhibitor with respect to OSB (K{sub i} = 11.2 {+-} 0.9 nM). These data are consistent with a Bi Uni Uni Bi Ping-Pong kinetic mechanism for these enzymes. In addition, OSB-AMS inhibits saMenE with K{sub i}{sup app} = 22 {+-} 8 nM and ecMenE with K{sub i}{sup OSB} = 128 {+-} 5 nM. Putative active-site residues, Arg222, which may interact with the OSB aromatic carboxylate, and Ser302, which may bind the OSB ketone oxygen, have been identified through computational docking of OSB-AMP with the unliganded crystal structure of saMenE. A pH-dependent interconversion of the free keto acid and lactol forms of the inhibitors is also described, along with implications for inhibitor design.

Se realiza una actualización de la evaluación diagnóstica del niño con parálisis cerebral. El diagnóstico de esta discapacidad es fundamentalmente clínico, lo cual comprende una anamnesia detallada de los factores de riesgo y del desarrollo psicomotor del niño, además del examen neuromotor. Resulta necesaria la aplicación de una serie de instrumentos para determinar el grado de limitación funcional y las alteraciones asociadas. Dentro de los exámenes complementarios, los exámenes neuroimaginológicos son los más importantes en la búsqueda de causas probables y la determinación del momento de la lesión cerebral. Otros exámenes (electroencefalograma, estudios genéticos, metabólicos y de coagulación tienen indicaciones específicas. Para la evaluación integral de estos niños se requiere del concurso de múltiples especialidades médicas, psicopedagógicas y sociales.Cerebral palsy is the most frequent physical disability in childhood.

La Corte Penal Internacional ha asumido este legado y hoy sabemos que, con o sin la complicidad de las autoridades del Estado, y a partir de la escasa jurisprudencia de la Corte Penal Internacional, estos grupos cometen crímenes de guerra como bien se estableció en la sentencia de Lubanga del 2012 y en Katanga del 2014 respectivamente. Crímenes de lesa humanidad a partir concretamente de la Decisión de Apertura de una Investigación para Kenia en 2010 donde la Sala a pesar de discrepancias adoptó la posición de que estos grupos organizados, con algún tipo de jerarquía y capaces de infringir los derechos humanos pueden ser considerados ‘organización’ en el sentido del artículo 7 del Estatuto de Roma.

  9. Par Pond vegetation status Summer 1995 -- Summary

    Mackey, H.E. Jr.; Riley, R.S.

    1996-01-01

    The water level of Par Pond was lowered approximately 20 feet in mid-1991 in order to protect downstream residents from possible dam failure suggested by subsidence on the downstream slope of the dam and to repair the dam. This lowering exposed both emergent and nonemergent macrophyte beds to drying conditions resulting in extensive losses. A survey of the newly emergent, shoreline aquatic plant communities of Par Pond began in June 1995, three months after the refilling of Par Pond to approximately 200 feet above mean sea level. These surveys continued in July, September, and late October, 1995. Communities similar to the pre-drawdown, Par Pond aquatic plant communities are becoming re-established. Emergent beds of maidencane, lotus, waterlily, and watershield are extensive and well developed. Cattail occurrence continued to increase during the summer, but large beds common to Par Pond prior to the drawdown have not formed. Estimates from SPOT HRV, remote sensing satellite data indicated that as much as 120 hectares of emergent wetlands vegetation may have been present along the Par Pond shoreline by early October, 1995. To track the continued development of macrophytes in Par Pond, future surveys throughout 1996 and 1997, along with the continued evaluation of satellite data to map the areal extent of the macrophyte beds of Par Pond, are planned

    2007-05-15

    The electric power industry is witnessing significant transformations dealing with the principles of the market organization. The reforms of the sector regulations modify the functioning rules, and in reply, the firms adapt their strategic behaviour through partner policies and alliances. Since 1996, several alliances cases have emerged. The present research work consists in the examination of motivations that are the origin of these partnerships inciting the big power companies to set off on a race to external growth. The first part of the thesis tackles the reconfiguration of the power industry in Europe and clarifies the different motivations of companies that decide to form an alliance (to get into a new market, pass the over capacities, search considerable effect engendering important economies and synergies, base an effect power and a safety motivation). The second part focuses on the study of EdF and Enbw links through the analysis of synergies brought out by such alliance and the construction of possible progress scenarios for this alliance (starting from the analysis of strategic intentions of both Allies, a scenario of success or break down is built up).

    European governments have decided, in the framework of the unique market, to open their national market to competition. Electricite de France (EdF), like the overall French public utilities, has to adapt to this new situation. The question is: how to perform this mutation and avoid ultra-liberalism? This is the main guideline of this book which aim is to define the modalities of the necessary implication of the government and the ones of a new kind of company governance in a sector where regulation errors can have dramatic consequences (like the power outage in the US). The objective of the author is not to propose a simple compromise between market and public utility logics, but to consider the double opening of markets and companies capital as new opportunities to improve both the public utility and the companies efficiency. Such a company 'of the third kind' (somewhere between governmental and private) can be built only if the new rules and reforms are made in a clever and profitable way, i.e. in compliance with sustainable development principles, in the respect of management transparency, and for the benefit of general people and in particular the end-users.

    Full Text Available El novedoso Protocolo de Nagoya regula el régimen internacional de acceso a recursos genéticos y distribución de beneficios. El mecanismo es capaz de ayudar mediante una distribución justa y equitativa de beneficios a conservar la diversidad genética, a compensar a las comunidades indígenas y locales por el uso de su conocimiento tradicional en relación con la utilización de la biodiversidad, y a reducir la brecha tecnológica existente entre los países del Norte y del Sur. Desafortunadamente experiencias previas al Protocolo de Nagoya demuestran que la implementación nacional de regímenes de acceso y distribución de beneficios ha resultado dificultosa e infructuosa debido a varias razones. Entre ellas se incluyen la existencia de lagunas legales y la falta de capacidades institucionales y científicas. Partiendo de esa realidad se adelanta una metodología útil para anticipar y analizar los aspectos positivos y negativos que presenta un país de cara a implementar un régimen de acceso y distribución de beneficios. La metodología se basa en el análisis de tres categorías elementales: a recursos genéticos del país proveedor y conocimiento tradicional a ellos asociado, b normas legales y políticas nacionales relacionadas con el acceso y distribución de beneficios  y c capacidades en investigación y desarrollo biotecnológico de las instituciones científicas del país proveedor de recursos genéticos que potencialmente pudieran estar involucradas en la distribución de beneficios. Se espera que su aplicación ayude a aquellos países que se encuentran actualizando o desarrollando regímenes nacionales de acceso y distribución de beneficios a asegurar una implementación exitosa del mecanismo.

    Hydro-ecology (or aquatic ecology) is the study of aquatic systems in their interacting aspects: physical, chemical and biological. The creation in 1974 of the Environment Department at EDF Research and Development Division marked the start in France of quantitative hydro-ecology applied to power generation installations. The studies developed around several main themes, determined both the expansion of the nuclear programme and by changes in French environmental regulations, in particular the 1976 law on impact studies, the 1984 fishing and hydro-biology law and the 1992 water law. In this framework, he effect of artificial warming of rivers, eutrophication of continental and marine waters, transfers of mineral micro-pollutants and radionuclides in rivers, and problems specific to hydropower installations such as guaranteed in stream flow or fish pass design, have been studies. This work, conducted in collaboration with many other laboratories, has led to the development of original quantitative approaches, notably in the field of numerical modelling. The paper selects several of the tools developed whose scope of application is wider than the environment and management of thermal or hydropower plants. Two major applications grouping the experience acquired in hydro-ecology are presented: the AGIRE software and the global environment study of the Singrauli area in India. (author)

    1979-01-01

    Because of the operational constraints relating to fuel behaviour, imperfect knowledge of the behaviour of a defective fuel assembly and, in the near future, the need to adapt reactor power to grid following (load following and remote control), EDF is aiming to reduce the present rate of fuel failure. While the phenomena affecting fuel behaviour have now been listed and analysed, the efforts at reducing their consequences have yet to be completed. This can be achieved, firstly, by reducing or eliminating fabrication defects, which are responsible for failure at the beginning of fuel life, through establishment of a good quality assurance organization and the search for still higher efficiency of quality control and fabrication equipment, and secondly, by developing fabrication techniques minimizing in particular cladding-pellet interactions and the stress corrosion of the cladding, which are responsible for fuel failure as from mid-life. However, the reactor operating conditions likely to apply in the near future may lead, for a given fuel configuration, to a re-evaluation of the fabrication parameters of cladding and UO 2 pellets.

    The monitoring of chemistry and radiochemistry parameters is a fundamental need in nuclear power plants in order to ensure: - The reactivity control in real time, - The barrier integrity surveillance by means of the fuel cladding failures detection and the primary-pressure boundary components control, - The water quality to limit the radiation build-up and the material corrosion permitting to prepare the maintenance, radioprotection and waste operations. - The efficiency of treatment systems and hence the minimization of chemical and radiochemical substances discharges The relevant chemistry and radiochemistry parameters to be monitored are selected depending on the chemistry conditioning of systems, the source term evaluations, the corrosion mechanisms and the radioactivity consequences. In spite of the difficulties for obtaining representative samples under all circumstances, the EPR M design provides the appropriate provisions and analytical procedures for ensuring the reliable and accurate monitoring of parameters in compliance with the specification requirements. The design solutions, adopted for Flamanville 3-EPR M and UK-EPR M , concerning the sampling conditions and locations, the on-line and analytical equipment, the procedures and the results transmission to control room and chemistry laboratory are supported by ALARP considerations, international experience and researches concerning the nuclides behavior (corrosion product and actinides solubility, fission product degassing, impurities and additives reactions also). This paper details the means developed by EDF for making successful and meaningful sampling and measurements to achieve the essential objectives associated with the monitoring. (authors)

    1964-01-01

    After resuming briefly the characteristics of the installations G2-G3 at Marcoule and EDF 1 at Chinon, the authors review the main aspects of the tests, the starting and the exploitation of these reactors. Among the various points examined, particular emphasis is given to the devices of original nature such as tubular fuel elements, flattening of the neutron flux by stuffing, behaviour of the reactor tanks and the cooling circuits, the blowers, unloading devices, regulation and functioning of the informations. This analysis deals equally with the performances obtained and the difficulties and the various incidents experienced during the initial starting period. Among the more interesting results, the progressive increase in the power of the Marcoule reactors is mentioned, obtained through a better knowledge of the parameters covering the functioning of the reactors such as the distribution of the flux and the temperatures etc... acquired during the course of the exploitation of the reactor. The conclusion reached by the authors is that the experience gained on these installations has shown: - that during an initial period, adjustments became necessary, all of which turned out to be possible, - that an analysis of their functioning has permitted the progressive movement towards a truly industrial exploitation.

    Full Text Available El trabajo parte de una revisión de la literatura sobre exclusión social. Se argumenta que la combinación de instituciones estatales, de mercado o comunitarias/familiares, que conforman los regímenes de bienestar en América Latina, son claves a la hora de generar o mitigar la exclusión social. La insuficiencia de las políticas sociales públicas empujan las personas y los hogares a promover su propio bienestar por medio del trabajo familiar no remunerado o de la contratación de servicios privados en el mercado. El acceso al mismo está condicionado a los recursos económicos disponibles, lo que deriva en una estratificación de las estrategias de bienestar y una segmentación de los servicios sociales. Ya que esos recursos se obtienen del mercado laboral o de transferencias públicas, el estudio de ambos aspectos es fundamental a la hora de analizar la exclusión social en la región

Deuxiemement, une etude sur la quasi-independance du parametre de penalisation de Tikhonov optimal par rapport a la dimension de l'espace de controle dans les problemes inverses d'estimation de fonctions spatialement dependantes est menee. Cette etude fait suite a une observation realisee lors de la premiere partie de ce travail ou le parametre de Tikhonov, determine par la methode " L-curve ", se trouve etre independant de la dimension de l'espace de controle dans le cas sous-determine. Cette hypothese est demontree theoriquement puis verifiee numeriquement sur un probleme inverse lineaire de conduction de la chaleur puis sur le probleme inverse non-lineaire de TOD. La verification numerique repose sur la determination d'un parametre de Tikhonov optimal, defini comme etant celui qui minimise les ecarts entre les cibles et les reconstructions. La demonstration theorique repose sur le principe de Morozov (discrepancy principle) dans le cas lineaire, tandis qu'elle repose essentiellement sur l'hypothese que les fonctions radiatives a reconstruire sont des variables aleatoires suivant une loi normale dans le cas non-lineaire.

    Many steam generators (SGs) equipped with 'mill-annealed' (MA) Alloy 600 tubings suffer significant secondary side corrosion. Until now, no degradation has been observed with either Alloy 600 TT or Alloy 690 for new SGs. The understanding of IGA/SCC of Alloy 600 MA in plants and the development of predictive models have become an important challenge to assess the life span and to reduce the maintenance costs of SGs. As degradation occurs in crevice environments which are varied and little known, EDF has undertaken an important program to improve the knowledge of crevice environments which lead to cracking. Corrosion tests are performed on Alloys 600 MA (also on 600 TT) in various environments in order to reproduce the deposits and the cracking observed on pulled tubes in laboratory conditions. Other corrosion tests are conducted in environments containing some pollutants identified by analyses of secondary water after hideout-return (sulfates) or oxidizing compounds : the influences of pH and potential are evaluated on Alloy 600 (MA or TT) and also on Alloys 690 and 800. A comprehensive model is proposed using IGA/SCC results of Alloy 600 in caustic environments. The thermomechanical parameters of the tubes and the field environmental conditions, introduced in the model, confirm some important features of SGs tubings. The model will be improved to include other detrimental environments. It will provide a useful tool to predict the life span (then steam generator replacements) and to optimize the maintenance policy of SGs still equipped with Alloys 600 MA and particularly with 600 TT (frequency and best locations of inspections). Margins will also be assessed for new SGs equipped with Alloy 690, and a comparison will be performed with Alloy 800. (author)

    Taxation of energy-dense foods (EDFs) and sugar-sweetened beverages (SSBs) is increasingly of interest as a novel public health and fiscal policy instrument. However academic interest in policy determinants has remained limited. We address this paucity by comparing the policy content and policy context of EDF/SSB taxes witnessed in 13 case studies, of which we assume the tax is sufficiently high to induce behavioural change. The observational and non-randomized studies published on our case studies seem to indicate that the EDF/SSB taxes under investigation generally had the desired effects on prices and consumption of targeted products. The revenue collection of EDF/SSB taxes is minimal yet significant. Administrative practicalities in tax levying are important, possibly explaining why a drift towards solely taxing SSBs can be noted, as these can be demarcated more easily, with levies seemingly increasing in more recent case studies. Despite the growing body of evidence suggesting that EDF/SSB taxes have the potential to improve health, fiscal needs more often seem to lay their policy foundation rather than public health advocacy. A remarkable amount of conservative/liberal governments have adopted these taxes, although in many cases revenues are earmarked for benefits compensating regressive income effects. Governments voice diverse policy rationales, ranging from explicitly describing the tax as a public health instrument, to solely explicating revenue raising. Copyright © 2017 Elsevier B.V.

    de reduire le temps de convergence des minimisations. Une difficulte des algorithmes de localisation en temps reel par la vision (SLAM monoculaire) est que la trajectoire estimee est souvent affectee par des derives: derives d'orientation, de position et d'echelle. Puisque ces algorithmes sont incrementaux, les erreurs et approximations sont cumulees tout au long de la trajectoire, et une derive se forme sur la localisation globale. De plus, un systeme de localisation par vision peut toujours etre ebloui ou utilise dans des conditions qui ne permettent plus temporairement de calculer la localisation du systeme. Pour resoudre ces problemes, nous proposons d'utiliser un capteur supplementaire mesurant les deplacements de la camera. Le type de capteur utilise varie suivant l'application ciblee (un odometre pour la localisation d'un vehicule, une centrale inertielle legere ou un systeme de navigation a guidage inertiel pour localiser une personne). Notre approche consiste a integrer ces informations complementaires directement dans l'ajustement de faisceaux, en ajoutant un terme de contrainte pondere dans la fonction de cout. Nous evaluons trois methodes permettant de selectionner dynamiquement le coefficient de ponderation et montrons que ces methodes peuvent etre employees dans un SLAM multi-capteur temps reel, avec differents types de contrainte, sur l'orientation ou sur la norme du deplacement de la camera. La methode est applicable pour tout autre terme de moindres carres. Les experimentations menees sur des sequences video reelles montrent que cette technique d'ajustement de faisceaux contraint reduit les derives observees avec les algorithmes de vision classiques. Ils ameliorent ainsi la precision de la localisation globale du systeme

    en partenariat avec la societe METALSCAN une technique d'imagerie ultrasonore multielements dediee au controle complet et automatique de soudures homogenes d'aciers Inox realisees par faisceau d'electrons. Pour atteindre cet objectif, une etude acoustique par simulation avec le logiciel CIVA a ete menee afin de determiner les caracteristiques optimales des sondes multielements (leur nombre et leur emplacement). Au final, la methode developpee permet, d'une part, de localiser des manques de fusion de soudure equivalents a des trous a fond plats de 0,5 mm de diametre, et d'autre part, de detecter des manques de penetration de 0,1 mm. Afin d'assurer une parfaite reproductibilite des controles, un systeme mecanique assurant la mise en rotation de la piece, permet d'inspecter l'ensemble de la soudure. Les resultats sont alors analyses automatiquement a l'aide d'un logiciel specifique assurant la tracabilite des controles. La methode a tout d'abord ete validee a l'aide de pieces etalons, puis elle a ete mise en service apres confrontation des resultats obtenus sur des defauts reels avec d'autres techniques (radiographie et caracterisations metallographiques).

  9. Crisis communication and EDF's power grid paralysis from the 1970's to the 2000's

    Gautreau, Arthur

    2009-01-01

    The power failure of 19 December 1978 and the storms of December 1999 were two critical moments in crisis communication for EDF. If the difficult situations or else the disasters were effectively anticipated, only these actual situations had allowed improving the Company's communication schemes and systems. Since the years 1950 and the program of hydraulic equipment, EDF had obviously developed a communication department that was enhanced with the launch of the nuclear program. Similarly, a 'crisis communication' was permanently ready, namely in the cases of storm or snowfall. The power failure of 19 December 1978 occurred whilst the company had an active scheme, but it is its sheer size that surprised. As it obliged to resort to the national media (radio) to inform the users without electricity. If the network had not been affected in 1978, things were quite different during the storms of 1999. And communication was then focused on mobilizing the Company's employees to restore electricity. In both cases, the feedback from experience has allowed to improve the communication schemes and systems

    Flow accelerated corrosion (FAC) is very effective for nuclear power plants. This generalized corrosion can lead to the rupture of pipes. EDF has developed during these 20 last years the software called BRT-CICERO for the surveillance of the secondary piping system of its Pressurized Water Reactors (PWRs). This software enables the operator to calculate the FAC wear rates taking into account all the influencing parameters such as: pipe isometrics, chromium content of the steel, chemical conditioning and operating parameters of the secondary circuit (temperature, pressure, etc.). This is a major tool for the operators to organize the maintenance and to plan the inspections. In the framework of the French pressure vessel law issued on March 15. 2000, the software BRT-CICERO has been recognized by the French authority for the FAC surveillance on the secondary pressure piping lines of the EDF 58 nuclear reactors. It takes advantage of the experience feedback of the French fleet and of the improvements. BRT-CICERO is frequently updated. A guideline is associated to BRT-CICERO to define the rules and the domain of use and to take advantage of all its functionalities. (authors)

    Full Text Available During the twentieth century, the countries of Central America were characterized by remarkably different political regimes: military-authoritarianism in Guatemala and El Salvador, progressive democracy in Costa Rica and traditional-authoritarianism in Honduras and Nicaragua. This article explains these contrasting regime outcomes by exploring the agrarian and state-building reforms pursued by political leaders during the nineteenth– and early twentieth century liberal reform period. Based on differences in the transformation of state and class structures, three types of liberalism are identified: radical liberalism in Guatemala and El Salvador, reformist liberalism in Costa Rica and aborted liberalism in Honduras and Nicaragua. It is argued that these types of liberalism set the Central American countries on contrasting paths of political development, culminating in diverse regime outcomes.Durante el siglo XX, los países de América Central se caracterizaron por tener regímenes políticos muy diferentes: el autoritarismo militar en Guatemala y El Salvador; la democracia progresista en Costa Rica y el autoritarismo tradicional en Honduras y Nicaragua. Este artículo explica los resultados de estos distintos regímenes mediante la exploración de las reformas agrarias y de la construcción del Estado llevadas a cabo por los líderes políticos durante el siglo XIX y principios del periodo de reformas liberales del siglo XX. Basándose en las diferencias de la transformación del Estado y de las estructuras de clases, se pueden identificar tres tipos de liberalismo: liberalismo radical en Guatemala y El Salvador; liberalismo reformista en Costa Rica y liberalismo frustrado en Honduras y Nicaragua. Se argumenta que estos tipos de liberalismo condujeron a los países de América Central a caminos contrarios al desarrollo político, culminando así en regímenes con resultados diversos.

    Full Text Available En la Argentina, los medios masivos de comunicación han construido a lo largo de los años diferentes modos de exhibir el consumo del cuerpo de la mujer. Teorías críticas y teorías feministas han alertado sobre estas arquetipaciones y estereotipaciones estigmatizantes que ubican a la mujer en un lugar de recepción de diferentes tipos de violencias. En este artículo nos proponemos no solo pensar y analizar qué sucede con las coberturas mediáticas de diferentes casos de “femicidios” que ocurrieron en los últimos años en la Argentina, sino también proponer analíticamente un modo de repensar las relaciones sociales de género en la cotidianeidad y en los medios masivos de comunicación. Pensamos que la perspectiva de género es central para poder desentrañar los vínculos de poder entre mujeres y varones y entre los medios masivos y la sociedad. Para ello realizaremos un recorrido con la intención de insistir en que no pueden hacerse lecturas, análisis, denuncias de los casos de femicidio si eso no conlleva una perspectiva de género acorde a los temas vinculados a la violencia social, incluso, puntualizar que las leyes aún resultan ambiguas a la hora de trabajar los crímenes de género. Las categorías y los casos que se estudiaron refieren a las búsquedas de las dos autoras en sus propias investigaciones vinculadas a la comunicación, la cultura y la problemática de género en la Argentina reciente que intentan dilucidar que, a veces, ciertas exposiciones referidas a la violencia de género no contemplan una perspectiva emancipadora del cuerpo de las mujeres, sino que, al contrario, intentan seguir manteniendo las relaciones desiguales y conservadoras resultantes del patriarcado. En este sentido, creemos que el modo de analizar la violencia de género es pensarla como una violencia social en su especificidad, con sus propias características y, fundamentalmente, no como un fenómeno que puede ser fácilmente consumido en el

También refleja las opiniones vertidas en la prensa española sobre la política diseñada por el coronel Carlos Ibáñez. Estas relaciones se basaron en las simpatías ideológicas de los dos regímenes que propiciaron unas conexiones muy intensas en diferentes ámbitos como fueron las de índole política y diplomática con la firma de un tratado de arbitraje y la elevación al máximo nivel de las respectivas legaciones; las de carácter militar con la formación de oficiales chilenos en escuelas españolas; y las de signo comercial con dos acuerdos, uno de rebaja de aranceles y otro para el internamiento de salitre en territorio español. Palabras Claves: Dictadura, España, Primo de Rivera, Chile, Ibáñez del Campo. ABSTRACT This work wants to emphasize the importance of the diplomatic and economic relations, which took place during Primo de Rivera and Ibáñez del Campo mandates, between Spain and Chile. For that purpose, there has been analyzed the diplomatic existing documentation in different Spanish and Chilean Archives. It also reflects the opinions written on the Spanish press about the politics designed by Colonel Carlos Ibanez. These relations were based on the ideological sympathy of both regimes which propitiated very intense connections in different areas, such the political and diplomatic areas with the arbitration agreement signature and the elevation to the maximum level of both legations, those of military character with the Chilean officials training in Spanish training centres, and those of commercial sign with two agreements, the reduction of duties and the internment of saltpetre in Spanish territory.

    In mammals, homologous chromosomes rarely pair outside meiosis. One exception is the X chromosome, which transiently pairs during X-chromosome inactivation (XCI). How two chromosomes find each other in 3D space is not known. Here, we reveal a required interaction between the X-inactivation center (Xic) and the telomere in mouse embryonic stem (ES) cells. The subtelomeric, pseudoautosomal regions (PARs) of the two sex chromosomes (X and Y) also undergo pairing in both female and male cells. PARs transcribe a class of telomeric RNA, dubbed PAR-TERRA, which accounts for a vast majority of all TERRA transcripts. PAR-TERRA binds throughout the genome, including to the PAR and Xic. During X-chromosome pairing, PAR-TERRA anchors the Xic to the PAR, creating a 'tetrad' of pairwise homologous interactions (Xic-Xic, PAR-PAR, and Xic-PAR). Xic pairing occurs within the tetrad. Depleting PAR-TERRA abrogates pairing and blocks initiation of XCI, whereas autosomal PAR-TERRA induces ectopic pairing. We propose a 'constrained diffusion model' in which PAR-TERRA creates an interaction hub to guide Xic homology searching during XCI.

  17. Analysis of thickness measurements on secondary lines in EDF PWRs to evaluate the accuracy of the flow accelerated corrosion monitoring software: BRT-CICERO

    The surveillance of Flow Accelerated Corrosion (FAC) on secondary pipes is a major concern for every nuclear power plant operator. After the Surry accident in 1986, EDF launched a computer code development program to monitor this degradation phenomenon. A chemical corrosion model has been developed, based on laboratory test results obtained by EDF R and D since the late 70's. This model enables to compute the wall thickness loss of pipes submitted to FAC, with respect to the thermo-hydraulic conditions, the fluid chemistry, the material chromium content, the pipe geometry and the cycles duration. The computer code, called BRT-CICERO(TM), has first been tested on a few plants in the years 1993-1995. Most of the EDF NPPs began to use it afterwards. In 2001, after the discovery of a severe damage on a 4'' x 6'' reducer at Fessenheim unit 2, that was correctly predicted by BRT-CICERO(TM), the EDF corporate level made its use mandatory for each of its 58 Pressurized Water Reactors (PWR). Several years of operation and experience feedback have enabled to carry out different improvements on the BRT-CICERO(TM) software. Since 2003, EDF NPPs are using the 2.2 version. At the beginning of year 2005, the 58 BRT-CICERO(TM) input-databases were gathered and structured in a form such that statistical treatments could be made. A very great number of data were collected from BRT-CICERO(TM) input-databases by a specific modification of a tool integrated into the software. It appears that a statistical approach could allow an effective analysis of these data. The first goal of this study was to give the degree of confidence in the application and this approach appeared effective. The second goal was to prove that a part of the conservatism is due to the FAC kinetics calculation algorithm implemented in BRT-CICERO(TM). The investigation of the relative difference between measured and calculated thicknesses shows that a part of the conservatism should be due to the FAC kinetics

  5. Macrophage Migration Inhibitory Factor Mediates PAR-Induced Bladder Pain.

    Directory of Open Access Journals (Sweden)

    Dimitrios E Kouzoukas

    Full Text Available Macrophage migration inhibitory factor (MIF, a pro-inflammatory cytokine, is constitutively expressed in urothelial cells that also express protease-activated receptors (PAR. Urothelial PAR1 receptors were shown to mediate bladder inflammation. We showed that PAR1 and PAR4 activator, thrombin, also mediates urothelial MIF release. We hypothesized that stimulation of urothelial PAR1 or PAR4 receptors elicits release of urothelial MIF that acts on MIF receptors in the urothelium to mediate bladder inflammation and pain. Thus, we examined the effect of activation of specific bladder PAR receptors on MIF release, bladder pain, micturition and histological changes.MIF release was measured in vitro after exposing immortalized human urothelial cells (UROtsa to PAR1 or PAR4 activating peptides (AP. Female C57BL/6 mice received intravesical PAR1- or PAR4-AP for one hour to determine: 1 bladder MIF release in vivo within one hour; 2 abdominal hypersensitivity (allodynia to von Frey filament stimulation 24 hours after treatment; 3 micturition parameters 24 hours after treatment; 4 histological changes in the bladder as a result of treatment; 5 changes in expression of bladder MIF and MIF receptors using real-time RT-PCR; 6 changes in urothelial MIF and MIF receptor, CXCR4, protein levels using quantitative immunofluorescence; 7 effect of MIF or CXCR4 antagonism.PAR1- or PAR4-AP triggered MIF release from both human urothelial cells in vitro and mouse urothelium in vivo. Twenty-four hours after intravesical PAR1- or PAR4-AP, we observed abdominal hypersensitivity in mice without changes in micturition or bladder histology. PAR4-AP was more effective and also increased expression of bladder MIF and urothelium MIF receptor, CXCR4. Bladder CXCR4 localized to the urothelium. Antagonizing MIF with ISO-1 eliminated PAR4- and reduced PAR1-induced hypersensitivity, while antagonizing CXCR4 with AMD3100 only partially prevented PAR4-induced hypersensitivity

    The 16th century by its passionate side has been the favourite one of authors of historical novels in which among the heroes of "cloak and dagger stories" appears sometime Ambroise Paré. Alexandre Dumas (the father) has shown him at the court of Charles IX in La Reine Margot (1845) where he does not however play a great role. On the contrary, Balzac in Le Martyr calviniste (1842) has given him a capital part close to the dying François II, whom he intended to trepanize but had to give up this idea as a consequence of the opposition of the queen-mother Catherine de Médicis. In the present century, Robert Merle in Paris ma bonne ville (Fortune de France, 3, 1980) shows Paré at the time of the Saint Barthélemy.

    Thrombin-induced platelet activation is initiated by PAR1 and PAR4 receptors. Vorapaxar, a PAR1 antagonist, has been assessed in patients with acute coronary syndromes (ACS) and stable atherosclerotic disease in addition to standard-of-care treatment. In clinical trials, vorapaxar has been observed to reduce the frequency of ischaemic events in some subgroups though in others has increased the frequency of bleeding events. Among patients undergoing CABG surgery, which is associated with excess thrombin generation, bleeding was not increased. The aim of these studies was to investigate the effects of selective PAR1 antagonism on thrombin-induced platelet activation in patients receiving vorapaxar or placebo in the TRACER trial and to explore the roles of PAR1 and PAR4 in thrombin-induced platelet activation in healthy volunteers. ACS patients receiving vorapaxar or placebo in the TRACER trial were studied at baseline and 4 hours, 1 and 4 months during drug administration. Thrombin-induced calcium mobilisation in platelet-rich plasma was assessed by flow cytometry. In vitro studies were performed in healthy volunteers using the PAR1 antagonist SCH79797 or PAR4 receptor desensitisation. Vorapaxar treatment significantly inhibited thrombin-induced calcium mobilisation, leaving a residual, delayed response. These findings were consistent with calcium mobilisation mediated via the PAR4 receptor and were reproduced in vitro using SCH79797. PAR4 receptor desensitization, in combination with SCH79797, completely inhibited thrombin-induced calcium mobilisation confirming that the residual calcium mobilisation was mediated via PAR4. In conclusion vorapaxar selectively antagonises the PAR1-mediated component of thrombin-induced platelet activation, leaving the PAR4-mediated response intact, which may explain why vorapaxar is well tolerated in patients undergoing CABG surgery since higher thrombin levels in this setting may override the effects of PAR1 antagonism through PAR4

From a practical point of view, we also try to compute improved equity measurement considering the case of EDF tariff for domestic customers. (author)

    2012-01-01

    As the world's biggest electricity generator, the EDF Group covers every sector of expertise, from generation to trading and transmission grids. EDF builds on the expertise of its people, its R and D and engineering skills, its experience as a leading industry operator and the attentive support of its customers to deliver competitive solutions that successfully reconcile economic growth with climate protection. This document presents the 2011 annual results and Consolidated financial statements of the Group at 31 December 2011: Group accounting standards; comparability; significant events and transactions; regulatory events in France; changes in the scope of consolidation; segment reporting; sales; fuel and energy purchases; other external expenses; personnel expenses; taxes other than income taxes; other operating income and expenses; prolongation of the transition tariff system (TaRTAM) - laws of June 7 and December 7, 2010; impairment / reversals; other income and expenses; financial result; income taxes; basic earnings per share and diluted earnings per share; operating assets and liabilities, equity; goodwill; other intangible assets; property, plant and equipment operated under French public electricity distribution concessions; property, plant and equipment operated under concessions for other activities; property, plant and equipment used in generation and other tangible assets owned by the group; investments in associates; inventories; trade receivables; other receivables; equity; provisions; provisions related to nuclear generation - back-end nuclear cycle, plant decommissioning and last cores; provisions for decommissioning of non-nuclear facilities; provisions for employee benefits; other provisions; special French public electricity distribution concession liabilities for existing assets and assets to be replaced; trade payable; other liabilities; current and non-current financial assets; cash and cash equivalents; current and non

  18. The market of nuclear plant dismantling. The new EDF's strategy, process standardisation, robotization: which perspectives for the market by 2030?

    International Nuclear Information System (INIS)

    2017-09-01

    Dismantling appears as the most promising activity in the nuclear sector due to ageing plants, to ambitious objectives of reduction of the nuclear share in the energy mix, or to high expertise of French companies in robotic and digital solutions for deconstruction in radioactive environments. However, the development of the dismantling market depends on EDF decisions: the extension of nuclear reactor lifetime postpones the development of this market. In this context, this study aims at giving an anticipated view of the plant dismantling market by 2030, at deciphering growth levers for the sector actors, and at understanding the sector operation and the business model of operators. Thus, the report presents the main components of the market (key figures, dismantling types, dismantling steps, sector ecosystem, barriers to enter the market, costs, contractual relationships), proposes an analysis of the market and of its perspectives (situation in France, and at the world level, predictive scenario for 2030), and discusses the development axes and demand evolutions (robotization and digitalisation, elaboration of standardised processes, management of wastes produced by nuclear dismantling, internationalisation of French actors). It also proposes an overview of actors in France, and identity sheets for commissioners (EDF, New Areva), contractors (Onet, Vinci, Engie), and other actors (Veolia, Assystem, Ortec, Cybernetix, Oreka Group). The last part proposes synthetic sheets for more than 110 companies of the sector (general information, management and financial performance data under the form of tables and figures) and comparative tables according to 5 key indicators. Data are presented for a period ranging from 2010 to 2016

    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

    Full Text Available This article studies the continued existence of subnational undemocraticregimes in Argentina and Mexico, two countries that have recently experiencednational democratization. The first part of the article offers a conceptualizationof subnational democracy and measures its territorial extension across all subnational units. The second part explores a common, albeit not systematically tested explanation about subnational undemocratic regime continuity, namely, that these regimes persist because they meet national incumbents’ strategic political needs. This claim is tested using statistical analyses to contrast patterns of spending across undemocratic subnational units during the presidencies of Menem (1989-1999, De la Rúa (2000-2001, Duhalde (2002, and Kirchner (2003-2007 in Argentina, and Fox (2000-2006 in Mexico. Contradicting conventional wisdom, the results show that presidents only reproduce a handful of subnational undemocratic regimes, as not all of them can meet presidential needs. In addition, the results reveal that the strategic calculation of presidents regarding this  reproduction is dictated by factors that have been largely overlooked by the literature. Este artículo estudia la existencia de regímenes subnacionales no-democráticos en Argentina y México, dos pa��ses que recientemente han experimentado procesos de democratización a nivel nacional. La primera parte del artículo conceptualiza y define la democracia subnacional y mide su extensión territorial en la totalidad de los distritos subnacionales. La segunda parte explora la validez de una de las explicaciones más habituales en esta área de estudio según la cual los regímenes subnacionales no-democráticos permanecen en el poder debido a que son útiles para satisfacer las necesidades políticas de los funcionarios nacionales. La validez de esta explicación se testea con análisis estadísticos que determinan los patrones de distribución territorial de

Este argumento complementa al que aparece en Plutarco, De Stoicorum Repugnantiis 1052C, pero descansa sobre una base distinta, a saber, la teoría de la disolución de los cuerpos complejos en los cuatro elementos y la teoría sobre cómo estos últimos se transforman los unos en los otros. Según veremos, existen antecedentes importantes de estas teorías en Anaxímenes y su teoría del cambio. Al final, me ocupo de dos objeciones que los propios estoicos formularon en contra del argumento de Crisipo.

    The film Taare Zameen Par (Stars upon the Ground) portrays the tormented life at school and at home of a child with dyslexia and his eventual success after his artistic talents are discovered by his art teacher at the boarding school. The film hints at a curious neurocognitive phenomenon of creativity in the midst of language disability, as exemplified in the lives of people like Leonardo da Vinci and Albert Einstein, both of whom demonstrated extraordinary creativity even though they were probably affected with developmental learning disorders. It has been hypothesized that a developmental delay in the dominant hemisphere most likely ‘disinhibits’ the nondominant parietal lobe, unmasking talents—artistic or otherwise—in some such individuals. It has been suggested that, in remedial training, children with learning disorders be encouraged to develop such hidden talents to full capacity, rather than be subjected to the usual overemphasis on the correction of the disturbed coded symbol operations.

    2005-01-01

    The Advanced Photon Source (APS) particle accumulator ring (PAR) is a 325-MeV storage ring that collects and compresses linac pulse trains into a single bunch for booster injection. A vertical beam instability has been observed when only a single linac bunch is injected and the total beam charge is from 0.15 to 0.7 nC. The instability starts about 80 ms after the injection, lasts about 160 ms, and is highly reproducible. We performed spectral measurement and time-resolved imaging with both a gated-intensified camera and a streak camera in order to characterize this instability. Initial analysis of the data indicates that the instability is due to ion trapping. A stable lattice was established as result of the investigation. This report summarizes the experimental results and gives some preliminary analysis.

    Protease-activated receptor-1 (PAR1) is the prototypic member of a family of four G-protein-coupled receptors that signal in response to extracellular proteases. In the peripheral nervous system, the expression and/or the role of PARs are still poorly investigated. High PAR1 mRNA expression was found in the rat dorsal root ganglia and the signal intensity of PAR1 mRNA increased in response to sciatic nerve transection. In the sciatic nerve, functional PAR1 receptor was reported at the level of non-compacted Schwann cell myelin microvilli of the nodes of Ranvier. Schwann cells are the principal population of glial cells of the peripheral nervous system which myelinate axons playing an important role during axonal regeneration and remyelination. The present study was undertaken in order to determine if the activation of PAR1 affects the neurotrophic properties of Schwann cells. Our results suggest that the stimulation of PAR1 could potentiate the Schwann cell ability to favour nerve regeneration. In fact, the conditioned medium obtained from Schwann cell cultures challenged with a specific PAR1 activating peptide (PAR1 AP) displays increased neuroprotective and neurotrophic properties with respect to the culture medium from untreated Schwann cells. The proteomic analysis of secreted proteins in untreated and PAR1 AP-treated Schwann cells allowed the identification of factors differentially expressed in the two samples. Some of them (such as macrophage migration inhibitory factor, matrix metalloproteinase-2, decorin, syndecan 4, complement C1r subcomponent, angiogenic factor with G patch and FHA domains 1) appear to be transcriptionally regulated after PAR1 AP treatment as shown by RT-PCR.

    This study sought to discover if an optimum 1 cm2 area in the non-damaged right hemisphere (RH) was present, which could temporarily improve naming in chronic, nonfluent aphasia patients when suppressed with repetitive transcranial magnetic stimulation (rTMS). Ten minutes of slow, 1 Hz rTMS was applied to suppress different RH ROIs in eight aphasia cases. Picture naming and response time (RT) were examined before, and immediately after rTMS. In aphasia patients, suppression of right pars triangularis (PTr) led to significant increase in pictures named, and significant decrease in RT. Suppression of right pars opercularis (POp), however, led to significant increase in RT, but no change in number of pictures named. Eight normals named all pictures correctly; similar to aphasia patients, RT significantly decreased following rTMS to suppress right PTr, versus right POp. Differential effects following suppression of right PTr versus right POp suggest different functional roles for these regions. PMID:21864891

  17. ParABS system in chromosome partitioning in the bacterium Myxococcus xanthus.

    Directory of Open Access Journals (Sweden)

    Antonio A Iniesta

    Full Text Available Chromosome segregation is an essential cellular function in eukaryotic and prokaryotic cells. The ParABS system is a fundamental player for a mitosis-like process in chromosome partitioning in many bacterial species. This work shows that the social bacterium Myxococcus xanthus also uses the ParABS system for chromosome segregation. Its large prokaryotic genome of 9.1 Mb contains 22 parS sequences near the origin of replication, and it is shown here that M. xanthus ParB binds preferentially to a consensus parS sequence in vitro. ParB and ParA are essential for cell viability in M. xanthus as in Caulobacter crescentus, but unlike in many other bacteria. Absence of ParB results in anucleate cells, chromosome segregation defects and loss of viability. Analysis of ParA subcellular localization shows that it clusters at the poles in all cells, and in some, in the DNA-free cell division plane between two chromosomal DNA masses. This ParA localization pattern depends on ParB but not on FtsZ. ParB inhibits the nonspecific interaction of ParA with DNA, and ParA colocalizes with chromosomal DNA only when ParB is depleted. The subcellular localization of ParB suggests a single ParB-parS complex localized at the edge of the nucleoid, next to a polar ParA cluster, with a second ParB-parS complex migrating after the replication of parS takes place to the opposite nucleoid edge, next to the other polar ParA cluster.

  19. Recombination in the human Pseudoautosomal region PAR1.

    Directory of Open Access Journals (Sweden)

    Anjali G Hinch

    2014-07-01

    Full Text Available The pseudoautosomal region (PAR is a short region of homology between the mammalian X and Y chromosomes, which has undergone rapid evolution. A crossover in the PAR is essential for the proper disjunction of X and Y chromosomes in male meiosis, and PAR deletion results in male sterility. This leads the human PAR with the obligatory crossover, PAR1, to having an exceptionally high male crossover rate, which is 17-fold higher than the genome-wide average. However, the mechanism by which this obligatory crossover occurs remains unknown, as does the fine-scale positioning of crossovers across this region. Recent research in mice has suggested that crossovers in PAR may be mediated independently of the protein PRDM9, which localises virtually all crossovers in the autosomes. To investigate recombination in this region, we construct the most fine-scale genetic map containing directly observed crossovers to date using African-American pedigrees. We leverage recombination rates inferred from the breakdown of linkage disequilibrium in human populations and investigate the signatures of DNA evolution due to recombination. Further, we identify direct PRDM9 binding sites using ChIP-seq in human cells. Using these independent lines of evidence, we show that, in contrast with mouse, PRDM9 does localise peaks of recombination in the human PAR1. We find that recombination is a far more rapid and intense driver of sequence evolution in PAR1 than it is on the autosomes. We also show that PAR1 hotspot activities differ significantly among human populations. Finally, we find evidence that PAR1 hotspot positions have changed between human and chimpanzee, with no evidence of sharing among the hottest hotspots. We anticipate that the genetic maps built and validated in this work will aid research on this vital and fascinating region of the genome.

    This thesis tries to answer the practical and theoretical problems of environment protection in the case of the hydropower branch of Electricite de France (EDF) company. These problems concern the contribution of the company to environment protection and the evaluation of this contribution. The work stresses on the synergic dimension (cooperation and negotiation) of the company/environment problem but also on the conflict dimension necessarily associated to this problem. The environmental management of a company has to deal with the complex game between the internal organisational stakes and the external relational strategies. A model is proposed which allows to evaluate the efficiency of a given environmental management system and to evaluate the participation of companies to this system with respect to the above listed points. Finally, some recommendations and elements of answers are proposed. (J.S.)

    EDF has a medium-scale test bench located at the CNPP, in Vernon. The experimental bench is used to study the fire behavior of combustible materials. The present paper deals with the main dynamic measures made during a test: in-bench temperatures, gas inlet and outlet flow rates, various chemical species concentration in fumes, loss of weight of the tested sample and heat released by its combustion. Moreover, the paper details the results of a calibration test which was carried out by injecting propane gas through a burner. The purpose of such a test was to supply the response of the bench instrumentation, and to check that heat released by gas combustion could be calculated using two different methods (O{sub 2} consumption and CO{sub 2} production). The test bench will be mainly used to investigate combustion of electric cable bundles. However, its use may be extended to study fire behavior of any fuel. (authors)

This comprises lessons from the Fukushima accident, the improvement of the 'internal explosion' referential by using a probabilistic study, the application of the seismic margin assessment approach as soon as possible, checking the absence of any 'cliff effect' for cooling functions, a deepened re-examination of hurricane frequencies in France. Other request by the ASN concern the verification of the pertinence of release authorizations, taking the TSN law into account, taking the AP1300 project into account, the expansion of the complementary domain, the project of reactor lifetime extension. Some technical requests are discussed in appendix

    Full Text Available Abstract Background The non-thrombotic effects of thrombin in cardiovascular tissues, as mediated via the protease activated receptors (PARs, and particularly PAR-1, have been the focus of much recent research. The aims of this study were to evaluate the effects of thrombin, a specific PAR-1 activating peptide (PAR1-AP, and a PAR-1 antagonist on human umbilical artery tone in vitro. Methods Human umbilical artery samples were obtained from 17 women at term. Arterial rings were suspended under physiologic conditions for isometric recording. The in vitro effects of thrombin (0.5 units/mL to 3 units/mL, PAR1-AP TFLLR-NH2 [10(-9 to 10(-6 M], and PAR-1 antagonist (N-trans cinnamoyl- p-fluoroPhe-p-guanidinoPhe-Leu-Arg-Orn-NH2 [10(-9 M to 10(-5 M] on umbilical artery tone were measured. Results Both thrombin and TFLLR-NH2 exerted a potent cumulative vasodilatory effect on human umbilical artery resistance (P 0.05. Conclusion These findings highlight a potential role for thrombin and PAR-1 receptors in vascular regulation of feto-placental blood flow in normal pregnancy, and in association with the vascular lesions associated with IUGR and pre-eclampsia.

  4. The 40 year deadline for the French nuclear stock. Decision process, strengthening option and costs associated with a possible lifetime extension beyond 40 years of EDF reactors

    Marignac, Yves

    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

  5. Current economic cost, the ARENH (Regulated Access to the Historic (EDF) Nuclear Energy Supplier) price, the differential rent and the scarcity rent of nuclear power: some observations

    International Nuclear Information System (INIS)

    Percebois, J.

    2012-01-01

    This article sets out to explain the ARENH mechanism, the regulated price at which the EDF (France's historic monopoly supplier) must sell part of its production to its competitors in the framework of the Nome Act (New Organisation of the Electricity Market). This price by its nature is different from the Current Economic Cost (CEC) of nuclear power, as estimated by France's Government Accounting Office in its report submitted in January 2012. These two approaches revert to the problem of the determination of the scarcity rent of nuclear power in the context of the liberalised European market, in which nuclear power benefits from a 'cost' advantage relative to thermal electricity generated from fossil fuels. Furthermore, scarcity rent is not the same thing as differential rent. Selling a nuclear kWh at the price of a 'gas' kWh at certain times results in a differential rent enabling nuclear generated power to cover fixed costs. One can only speak of scarcity rent for nuclear power when the price at which the kWh is sold allows the recovery of more than is necessary to cover overall costs of nuclear power and it is this scarcity rent and its allocation that is the subject of debate.

  6. Statement of the IRSN on the safety re-examination assessment made by EDF within the frame of the third decennial inspection of the 900 MW reactors

    International Nuclear Information System (INIS)

    2008-01-01

    The IRSN (the French Institute of Radioprotection and Nuclear Safety) here presents an assessment of the studies performed by EDF within the frame of the safety re-examination associated to the third decennial inspections of the 900 MW reactors, and of the modifications resulting from these studies with respect to the originally defined objectives of this re-examination. The aim of this report is to allow the ASN (Autorite de Surete Nucleaire, the Nuclear Safety Authority) stating the 900 MW reactor ability to carry on their operation until the fourth decennial inspections. Different themes and studies are assessed: internal and external aggressions (flooding, explosions, fire, seismic control, and climatic aggressions), accident assessments and their radiological consequences (failure of various components, the performing of probabilistic studies, confining procedures, structures and devices, etc.), operation and design of various systems and of civil engineering works. Several documents or extracts of official reports are given in appendix, expressing notably various recommendations on the here-above topics

  7. Movement and equipositioning of plasmids by ParA filament disassembly

    DEFF Research Database (Denmark)

    Ringgaard, Simon; van Zon, Jeroen; Howard, Martin

    2009-01-01

    Bacterial plasmids encode partitioning (par) loci that confer stable plasmid inheritance. We showed previously that, in the presence of ParB and parC encoded by the par2 locus of plasmid pB171, ParA formed cytoskeletal-like structures that dynamically relocated over the nucleoid. Simultaneously......, the par2 locus distributed plasmids regularly over the nucleoid. We show here that the dynamic ParA patterns are not simple oscillations. Rather, ParA nucleates and polymerizes in between plasmids. When a ParA assembly reaches a plasmid, the assembly reaction reverses into disassembly. Strikingly......, plasmids consistently migrate behind disassembling ParA cytoskeletal structures, suggesting that ParA filaments pull plasmids by depolymerization. The perpetual cycles of ParA assembly and disassembly result in continuous relocation of plasmids, which, on time averaging, results in equidistribution...

  11. PSD-Constrained PAR Reduction for DMT/OFDM

    Common to all DMT/OFDM systems is a large peak-to-average ratio (PAR), which can lead to low power efficiency and nonlinear distortion. Tone reservation uses unused or reserved tones to design a peak-canceling signal to lower the PAR of a transmit block. In DMT ADSL systems, the power allocated to these tones may be limited due to crosstalk issues with many users in one twisted pair bundle. This PSD limitation not only limits PAR reduction ability, but also makes the optimization problem more challenging to solve. Extending the recently proposed active set tone reservation method, we develop an efficient algorithm with performance close to the optimal solution.

  12. Protease-activated receptor (PAR2, but not PAR1, is involved in collateral formation and anti-inflammatory monocyte polarization in a mouse hind limb ischemia model.

    Lisa G van den Hengel

    Full Text Available AIMS: In collateral development (i.e. arteriogenesis, mononuclear cells are important and exist as a heterogeneous population consisting of pro-inflammatory and anti-inflammatory/repair-associated cells. Protease-activated receptor (PAR1 and PAR2 are G-protein-coupled receptors that are both expressed by mononuclear cells and are involved in pro-inflammatory reactions, while PAR2 also plays a role in repair-associated responses. Here, we investigated the physiological role of PAR1 and PAR2 in arteriogenesis in a murine hind limb ischemia model. METHODS AND RESULTS: PAR1-deficient (PAR1-/-, PAR2-deficient (PAR2-/- and wild-type (WT mice underwent femoral artery ligation. Laser Doppler measurements revealed reduced post-ischemic blood flow recovery in PAR2-/- hind limbs when compared to WT, while PAR1-/- mice were not affected. Upon ischemia, reduced numbers of smooth muscle actin (SMA-positive collaterals and CD31-positive capillaries were found in PAR2-/- mice when compared to WT mice, whereas these parameters in PAR1-/- mice did not differ from WT mice. The pool of circulating repair-associated (Ly6C-low monocytes and the number of repair-associated (CD206-positive macrophages surrounding collaterals in the hind limbs were increased in WT and PAR1-/- mice, but unaffected in PAR2-/- mice. The number of repair-associated macrophages in PAR2-/- hind limbs correlated with CD11b- and CD115-expression on the circulating monocytes in these animals, suggesting that monocyte extravasation and M-CSF-dependent differentiation into repair-associated cells are hampered. CONCLUSION: PAR2, but not PAR1, is involved in arteriogenesis and promotes the repair-associated response in ischemic tissues. Therefore, PAR2 potentially forms a new pro-arteriogenic target in coronary artery disease (CAD patients.

    This paper deals with 3D electromagnetic modelling of a transformer so as to evaluate eddy current losses in the tank. In this purpose, several numerical methods have been used with two 3D softwares, FLUX3D (LEG) and TRIFOU (EDF). These methods use either nodal finite elements with the magnetic vector potential (FLUX3D), or the edge finite elements with the magnetic field as the state variable (TRIFOU). Classical volume elements and several special elements have been used : shell elements with the magnetic vector potential for the modelling of thin conducting regions, and surface elements for conducting regions with a small skin depth. The results given by these methods with several characteristics of the tank and magnetic core have been compared and their validity domain has been verified. The shell elements suit well when the skin depth is larger than the tank thickness, whereas in the opposite case, the surface elements for thin skin depth regions are well adapted. Nous présentons la modélisation tridimensionnelle d'un transformateur pour la détermination des pertes par courants de Foucault dans sa cuve. Pour cela, plusieurs méthodes numériques ont été utilisées à l'aide de deux codes de calcul tridimensionnels : FLUX3D (LEG) et TRIFOU (EDF). Ces méthodes utilisent soit les éléments finis nodaux avec le potentiel vecteur magnétique (FLUX3D), soit les éléments finis d'arête avec le champ magnétique comme variable d'état (TRIFOU). Outre l'utilisation des éléments volumiques, nous avons employé des éléments surfaciques de type coque en potentiel vecteur magnétique pour la modélisation de regions conductrices minces, ainsi que des éléments surfaciques pour les régions conductrices présentant une faible épaisseur de peau. Les résultats obtenus avec ces méthodes pour différentes caractéristiques du matériau de la cuve et du circuit magnétique ont permis de vérifier leur domaine de validité. Les éléments de type coque conviennent

  14. Positron Accumulator Ring (PAR) power supply

    Fathizadeh, M.

    1995-01-01

    The Positron Accumulator Ring (PAR) consists of 8 dipole magnets connected in series. These magnets are energized via one 12-pulse dc power supply. The power supply consists of four phase controlled half-wave wye group converters. Each of the two half-wave converters are connected through an interphase transformer to obtain a full-wave converter with 120 degrees conduction. The input voltage for these two half-wave converters are 180 degrees apart. The two full-wave converters are connected in parallel through a third interphase transformer. This type of connection of the converters not only provides the required output current, it also improves the input power factor of the power supply. The output of the wye group converters is filtered through a passive L-R-C filter to reduce the ripple content of the output current. At low current values of the power supply the current ripple is high, thus a large filter is needed, which adds to the cost of the power supply, however at high output current levels, the current ripple is less severe. The large size of the filter can be reduced by adding an anti-parallel rectifier diode(D1) to the output of the power supply. A freewheeling diode(D2) is connected before the choke to circulate the current once the power supply is turned off. In order to measure the current in the magnet a high precision, low drift, zero flux current transductor is used. This transductor senses the magnet current which provides a feedback signal to control the gating of the converter's thyristors. A true 14 bit Digital to Analog Converter (DAC) is programmed by the control computer for the required current value, providing a reference for the current regulator. Fast correction of the line transients is provided by a relatively fast voltage loop controlled by a high gain slow response current loop

    Full Text Available El término parálisis cerebral (PC engloba a un gran número de síndromes neurológicos clínicos, de etiología diversa. Estos síndromes se caracterizan por tener una sintomatología común: los trastornos motores. Algunos autores prefieren manejar términos como "encefalopatía fija", "encefalopatías no evolutivas". Se mencionan la utilidad de programas de intervención temprana y métodos especiales de rehabilitación, así como el manejo de las deficiencias asociadas como la epilepsia, deficiencia mental, trastornos del lenguaje, audición, visión, déficit de la atención que mejoran el pronóstico de manera significativa. El pronóstico también depende de la gravedad del padecimiento y de las manifestaciones asociadas.The term cerebral palsy (CP, is used for a great number of clinical neurological syndromes. The syndromes are characterized by having a common cause, motor defects. It is important, because they can cause a brain damage by presenting motor defects and some associated deficiencies, such as mental deficiency, epilepsy, language and visual defects and pseudobulbar paralysis, with the nonevolving fact. Some authors prefer using terms such as "non-evolving encephalopathies". In the treatment the utility of prevention programs of early stimulation and special rehabilitation methods, and treatment of associated deficiencies such as epilepsy, mental deficiency, language, audition and visual problems, and the attention deficit improve the prognosis in an important way. The prognosis depends on the severity of the disease and the associated manifestations.

    Full Text Available Si bien en un primer momento las políticas europeas de conciliación se impulsaron desde un compromiso claro con la igualdad de oportunidades entre hombres y mujeres, en la última década las políticas de conciliación se han desarrollado principalmente en el marco de la política europea de empleo, esto es, se han considerado parte de una estrategia más amplia diseñada para promover el pleno empleo en la Unión Europea. El objetivo de estas políticas se ha convertido así en la creación de una sociedad de “dos sustentadores”, esto es, una sociedad de pleno empleo en la que tanto los varones como sus compañeras se dediquen al trabajo remunerado. Dada la diversidad de países que conforman la Unión Europea, podemos presumir que este objetivo político no representa lo mismo para todos, sino que exige un esfuerzo mayor para los regímenes de bienestar mediterráneos, caracterizados habitualmente por el subdesarrollo de sus políticas del bienestar, por su familiarismo y por sus bajas tasas de empleo femenino. El presente artículo ofrece precisamente una descripción y una evaluación las políticas de conciliación de los regímenes de bienestar mediterráneos, concretamente de Italia y España, desde el punto de vista de su potencial desfamiliarizadorAlthough European reconciliation of work and family life policies were at the beginning driven by a clear compromise with equal opportunities between men and women, in the last decade they have been mainly developed as part of the European employment policy. The objetive of those policies has thus turn into the promotion of a “dual earner” society, that is, a full employment society in which both men and women participate in paid employment. Given the diversity of countries which shape the European Union, this political objetive must have different implications for every country. It obviously demands a greater policy effort in the Mediterranean countries, whose welfare regimes have
