    The first nuclear power plant in the Federal Republic of Germany started operation in 1961. It was followed by a consistent period of development until a new energy source had become available by the late sixties which was both powerful and capable of expansion. With 1200 MW electric power, the pressurized water reactor of Biblis A in 1974 was equipped with the world's most powerful single-shaft turbine generator. In 187,656 hours of operation, Biblis A over the past thirty years generated slightly more than 211 billion kWh of gross electricity (by July 31, 2004). The operating experience accumulated also resulted in improvements and modifications of technical plant systems in the 1970s and 1980s which served to bring the unit up to the then current state of the art. Modifications of technical plant systems serving to increase the safety margins or improve operating systems, always in the light of the state of the art, have been carried out consistently and continuously over the years. In combination with a high level of qualification of the operating personnel, which is ensured by an efficient system of primary and refresher training courses of responsible shift personnel and other groups of power plant personnel, this creates a lasting foundation of safe plant operation. In connection with the preparations for, and the execution of, revision outages, Biblis provided the first experience with a PWR of this size category. Unit A of the Biblis nuclear power station is proof of the fact that technical and safety challenges can be solved, and have been solved, by engineering expertise. The high availability and low susceptibility to failure of the plant demonstrate the widely optimized maintenance strategy and the high qualification and motivation of the staff. (orig.)

    2002-04-01

    In the business year from 1 January through to 31 December 2001, Kernkraftwerk Brunsbuettel GmbH achieved a gross electric output of 6,010 GWh. The total net output transmitted to the two partner utilities Hamburger Electricitaets-Werke AG (HEW) and E.ON Kernkraft GmbH (E.ON KK) amounted to 5,764 GWh. Although the availability time ratio was 94.1 % (94.4 % previous year), the capacity factor was only 85.3 % (85.6 % previous year). This was due to postponement of the refuelling operation, spent fuel transports away from the reactor being delayed as a consequence of the political situation. The resulting considerable period of stretch-out operation with declining power output reduced the net output to 498 GWh. Otherwise, the capacity factor could have been 92.7 %. The short shutdown period of 23 days for power plant inspection inclusive of refuelling operation (20 days previous year) has had a positive impact on the operating data of the year 2001. The aggregate total gross electric output generated by the power station since it is operated by Kernkraftwerk Brunsbuettel GmbH amounts to 98,032 GWh. (orig./CB) [de

    Full Text Available The idea underlying BibliOpass is very simple: extending borrowers' rights to all libraries participating in the network. As in other countries, users of Swiss libraries are more and more mobile, especially the categories of students, teachers or researchers. Universities and technology institute have become more specialized and less general, aiming to improve their reputation at an international level. Students often need to visit different universities during their studies. BibliOpass supports this trend regarding library use in relation to this new mobility. Strangely, similar projects in other countries are not so frequent: Sconul Research Extra in Great Britain which groups together more than 150 higher education institutions is the best example. Basically, BibliOpass makes it simpler for a borrower to use other libraries. More than 600 libraries throughout the country are at present involved in the BibliOpass network. A patron registered as a ‘normal user’ in his or her main library (called ‘Home library’ may borrow items in any other library (called ‘Guest library’ without needing to obtain a new user card or paying extra fees. The user must observe the rules of the guest library (for example number of items and duration of loan. Items must be returned to their originating library for management reasons. BibliOpass is a new, complementary service to Inter Library Loan (ILL, the traditional way to obtain books from other libraries.

    1991-01-01

    Valves and piping of the pressurizer safeguarding system are exchanged and reset in such a way that they are suitable not only for discharging steam, but also for discharging a water-steam mixture and hot pressurized water; for the emergency measure of primary depressurization by hand (bleed) in the event of failure of the entire feedwater supply and station black-out, and in the event of operational transients with supposed failure of the reactor scram (ATWS). To achieve this, in addition to the requirements of the pressurizer discharging station, changes have to be made to the valve drive to dominate the water loads. During the 1990 inspection this exchange of the pressurizer discharging station was performed at the Biblis A unit as the first German plant. (orig.) [de

    In the appeal proceedings, the Bavarian Administrative Court with its interim decision of April 9, 1979 - No. 167 VI 74 - has recognized the action of the city of Schweinfurt against the state of Bavaria to set aside the 1st part license for the construction of Kernkraftwerk Grafenrheinfeld, although the right for action was limited to the city's legal position concerning planning authority, drinking water supply, and a city-owned lake used for swimming. Appeal was allowed. The city has lodged an appeal. The decision of the Administrative Court of Wuerzburg of March 25, 1977, which was contested by the appeal, had also recognized the city's rights but dismissed the action as being unfounded. Guidelines and reasons for the decision of the Bavarian Administrative Court are given in full wording. (orig./HP) 891 HP/orig.- 892 HIS [de

  14. The mitochondrial genome of Cethosia biblis (Drury) (Lepidoptera: Nymphalidae).

    2016-07-01

    We present the complete mitogenome of Cethosia biblis (Drury) (Lepidoptera: Nymphalidae) in this article. The mitogenome was a circle molecular consisting of 15,286 nucleotides, 37 genes, and an A + T-rich region. The order of 37 genes was typical of insect mitochondrial DNA sequences described to date. The overall base composition of the genome is A (37.41%), T (42.80%), C (11.87%), and G (7.91%) with an A + T-rich hallmark as that of other invertebrate mitochondrial genomes. The start codon was mainly ATA in most of the mitochondrial protein-coding genes such as ND2, COI, ATP8, ND3, ND5, ND4, ND6, and ND1, but COII, ATP6, COIII, ND4L, and Cob genes employing ATG. The stop codon was TAA in all the protein-coding genes. The A + T region is located between 12S rRNA and tRNA(M)(et). The phylogenetic relationships of Lepidoptera species were constructed based on the nucleotides sequences of 13 PCGs of mitogenomes using the neighbor-joining method. The molecular-based phylogeny supported the traditional morphological classification on relationships within Lepidoptera species.

    Pamme, H.; Roess, P.H.

    1996-01-01

    Results of French probabilistic PWR-studies indicated a high contribution of shut down states to the overall plant risk. Mainly inspired by these results qualitative and also probabilistic analyses were started in Germany since 1991. As the Biblis-B-NPP was already reference plant of the German Risk Study first studies of shut-down-states were again focuses on Biblis-B. These studies were mainly performed by the German Association for Reactor Safety (GRS) in close cooperation with the utility RWE Energie AG. This paper briefly reviews the chosen approach to model and assess shut-down-states at Biblis-NPP. An in-depth-presentation is focuses on the quantification of risk in mid-loop-operation (MLO) which was performed by the authors with intensive support of plant personnel

  16. Kernkraftwerke Lippe-Ems (KLE). 1997 annual report

    1998-01-01

    The Kernkraftwerke Lippe-Ems GmbH (KLE) is the operator of the Emsland reactor station at Lingen (Ems), equipped with a 1300 MW PWR. The partners of KLE are VEW ENERGIE, PreussenElektra, and RWE Energie. The nuclear power station was used over the reporting period as a base-load power plant operating under full-load conditions. The total gross electricity output was 11235 million kWh, which is the highest annual total output ever since start-up. The net electricity generation over the reporting amounted to 10650 million kWh. The personnel employed with KLE at the end of the reporting year amounts to 287. The reduction of the nominal capital of the GmbH to 900 000 TDM, decided by the partners in 1996, became legally effective in April 1997. The dominant features of the structure of expenses of KLE are expenses for the fuel inventory and spent fuel management, for the legally required reserves for decommissioning, and writeoffs. The contractual electric power rates negotiated with the partners cover all load and capacity-dependent expenses; in addition, the partners receive their contractual shares of the profit resulting from interests paid on the nominal capital.

    2006-01-01

    Over the past thirty years, unit B of the Biblis nuclear power station has contributed towards safe, reliable and non-polluting electricity generation. Unit B was the first 1,300 MW unit in the world confirming the good experience accumulated in the construction and operation of plants this size. It laid the foundation for the advanced development of nuclear power plants up to the convoy line. The good availability this plant has achieved in its operating cycles proves the mature state of technology and the high level of qualification and motivation of the power plant staff and the personnel of external firms contracted to work for Biblis. Biblis B has served as a reference plant in German nuclear safety research, demonstrating that units this size can be operated safely. Unit B is also living proof of the possibility to raise nuclear power plants built in the seventies to the current state of the art by implementing the appropriate backfitting and modernization measures. Today, Biblis B is operated at a safety level clearly higher than that to be achieved for new plants internationally. This is also evident from comparison with the guiding values for the safety of new facilities as published by the International Atomic Energy Agency (IAEA). (orig.)

    SACI-2 is a computer code created to study the dynamic behaviour of a PWR nuclear power plant. To evaluate the quality of its results, SACI-2 was used to recalculate commissioning tests done in BIBLIS-A nuclear power plant and to calculate postulated transients for Angra-2 reactor. The results of SACI-2 computer code from BIBLIS-A showed as much good agreement as those calculated with the KWU Loop 7 computer code for Angra-2. (E.G.) [pt

    1978-01-01

    In the Biblis station, instalment A, of the Rheinisch-Wesfaelisches-Elektrizitaetswerk, a study was conducted in 1977 to determine the doses received as a function of work carried out. The aim was to establish in a general study the dose which appears in each case during work on systems (or components of systems) in the active zone. An attempt was made as far as possible to relate the doses to specific occupations. This correlation is governed in two ways by conditions inherent in the organisation of the Biblis station a) maintenance and repair work are carried out under work contracts; the dose can be related to this work by the order number of the contract in question. b) Some activities, apart from maintenance and repair may be carried out without a contract. The dose which then appears is related to the type of activity concerned

  3. Chemical aspects of the treatment of radioactive concentrates at the nps Biblis

    International Nuclear Information System (INIS)

    Paffrath, G.; Schroeder, H.J.

    1983-01-01

    The methods of waste treatment in the Federal Republic of Germany can be separated in two periods and pathways. (1) Treatment of liquid waste by cementation and packing due to the doserate on the surface in drums of 400 litres, in drums of 200 litres put in drums of 400 litres and grout the space between the drums with cement. For higher doserates on the surface 200 litre drums could also be shielded by additional concrete shieldings. The limiting factors for this method of waste treatment were defined in the ASSE regulations. The treatment took place in transportable units at the reactor site. (2) Drying the concentrate and packing the product in thick-walled drums of cast-iron. This treatment, known as 'volume reducing' methods, was first practised in 1981 at the nps Biblis and took into account that: (1) at the reactor site exists only a storage capacity for liquid concentrates for one year and (2) after the closing of the experimental storage ASSE there was no prospect of an early final storage assembly in Germany. The methods are discussed. (author)

    Highlights: •Metaheuristics were applied to Loading Pattern Optimization problems and compared. •The problems are based on data of the benchmarks IAEA and BIBLIS. •The metaheuristics compared were PSO, Cross-Entropy, PBIL and Artificial Bee Colony. •Angra 1 NPP data were also used for further comparison of the algorithms. -- Abstract: The Loading Pattern Optimization (LPO) of a Nuclear Power Plant (NPP), or in-core fuel management optimization, is a real-world and prominent problem in Nuclear Engineering with the goal of finding an optimal (or near-optimal) Loading Pattern (LP), in terms of energy production, within adequate safety margins. Most of the reactor models used in the LPO problem are particular cases, such as research or power reactors with technical data that cannot be made available for several reasons, which makes the reproducibility of tests unattainable. In the present article we report the results of LPO of problems based upon reactor physics benchmarks. Since such data are well-known and widely available in the literature, it is possible to reproduce tests for comparison of techniques. We performed the LPO with the data of the benchmarks IAEA-3D and BIBLIS-2D. The Reactor Physics code RECNOD, which was used in previous works for the optimization of Angra 1 NPP in Brazil, was also used for further comparison. Four Optimization Metaheuristics (OMHs) were applied to those problems: Particle Swarm Optimization (PSO), Cross-Entropy algorithm (CE), Artificial Bee Colony (ABC) and Population-Based Incremental Learning (PBIL). For IAEA-3D, the best algorithm was the ABC. For BIBLIS-2D, PBIL was the best OMH. For Angra 1 / RECNOD optimization problem, PBIL, ABC and CE were the best OMHs.

  8. Poolside fuel assembly inspection campaigns performed at Kernkraftwerk Leibstadt during summer 1997

    International Nuclear Information System (INIS)

    1998-01-01

    In order to minimise fuel cycle costs, fuel assembly discharge burnup and average U-235 enrichment were increasing over past years in the Kernkraftwerk Leibstadt (KKL) plant. In parallel, high burnup verification programs were defined in collaboration with fuel suppliers. The aim of these programs is to demonstrate safe and reliable fuel performance up to the designed burnup limit and to identify any problems in due time. This is not only achieved by detailed poolside inspections of lead test assemblies, but also by hot cell post-irradiation examination of selected rods. In the frame of a hot cell examination campaign, enhanced localised corrosion in the vicinity of spacers on SVEA-96 fuel rods was identified in May 1997 as a potential problem. The average rod burnup of the investigated rods was around 50 MWd/kgU after 5 one year cycles of operation. As fuel operation up to six cycles is foreseen in KKLs fuel management plants, the risk of fuel failures caused by enhanced localised corrosion could not be excluded. An action plan was therefore developed in order to identify the root cause. Part of the action plan were two poolside inspection campaigns: 1. Visual inspection of 38 assemblies unloaded during refuelling outage 1996 after 5 cycles in operation. This campaign was performed in June 1997. It gave a broader data base to develop a concept for fuel management for the upcoming refuelling outage scheduled in August 1997. 2. Visual inspection, oxide layer thickness measurements, crud sampling and rod diameter measurements on 29 assemblies with different operation histories. This campaign was performed during the outage. A large portion of the inspected bundles was re-inserted for continued operation. The collected data confirmed that assumptions made for reload licensing and safety analyses were conservative. The inspection campaigns performed at KKL during summer 1997 by ABB Atom demonstrated that it is possible to address unexpected problems in a short time

    After four years of operation of the make up water treatment plant of nuclear POWER STATION BIBLIS an examination was made concerning the total through put, the eluation of ions and organic matters, and further concerning the efficiency of a special regeneration technique for the counter current regenerated ion exchange beds. In order to determine the efficiency of the applied regeneration methods analisis were carried out on a great number of water samples for sodium, chloride, COD and humic acids as well. A comparison was made between the anialytical determination of Sodium with an automatic analyser and the method used in the laboratory by means of flame photometry respectively ion potential measurement.

    The reactor monitoring instruments are important for the operation and safety of the plants. Static properties of the instruments are controlled annually, but the dynamic properties are rarely, if ever, examined. This study is the result of a project initiated by the Swedish Nuclear Power Inspectorate. The examinations are based on signal analysis and simultaneous measurement of multiple signals. Results from Oskarshamn 2 (O2), Barsebaeck 2 (B2) and Kernkraftwerk Muehleberg (KKM) are discussed in this report. The presentation is focused on reactor pressure and reactor level signals. the analysis of O2 revealed that the dynamics for 3 out of 14 sensors was 'filtered', meaning that a rapid level displacement is registered with delay. Inspection showed that a 1 sec filter was installed instead of 1.2 sec. The study also showed that old pressure-sensors in use both at O2 and B2 could not cope with high frequencies, and that some level-sensors were disturbed by mechanical oscillations at Bw. At KKM, a 2 Hz resonance was observed with 12 pressure and level sensors. The oscillation was created by an old pressure sensor and influenced the other sensors through the common impulse network

    Full Text Available Dos horizontes arquivísticos e de seu sentido É significativo observar que a discussão sobre Arquivologia e sobre as práticas profissionais arquivisticas tem avançado muito nos últimos anos no Brasil, e as razões são claramente apontadas pelos organizadores desta edição especial de Encontros Bibli em seu texto editorial. Contendo sete artigos, esta edição temática traz o título Horizontes Arquivísticos.Para dar vida a este número, foi desenvolvido um trabalho de quase dois anos, liderado pelo pesquisador José Maria Jardim e colaboração de Renata Silva Borges. Aqui estão reunidos nove autores e seis avaliadores, todos vinculados a instituições de ensino e de pesquisa ligadas ao Serviço Público Federal, com sede nas cidades de Brasilia, Rio de Janeiro, Niteroi e Florianópolis: UNB, UNIRIO, UFF, UFRJ, UFSC, Arquivo Nacional e FIOCRUZ.Neste momento da história brasileira ─ em que se anunciam políticas governamentais em prol da cidadania, em que se diz da disposição de resgate da verdade sobre os fatos políticos acontecidos na gestão do estado brasileiro dos anos de 1964 a 1989 ─ os arquivos e seus profissionais passam a divisar um relevante protagonismo. Pode-se dizer que, de certa maneira, deu-se um movimento de preparação deste protagonismo e que, simultaneamente, essa preparação alicerçou a percepção de segmentos importantes do setor público para oferecer essa perspectiva para a sociedade nacional.Nesse sentido, tem peso relevante a instalação de novos cursos de bacharelado na área, totalizando, em 2011, o número de 14 universidades que os oferecem: UNIRIO, UFF, UFSM, UFES, UNB, UEL, UFBA ,UNESP/MARÍLIA, UFRGS, UEPB, UFAM, FURG, UFMG, UFSC. Uma nota marcante é que todas essas Instituições de Ensino Superior têm vínculos governamentais, sendo onze federais e três estaduais.

    Convoy-type nuclear power plant maintenance is subject to the specifications contained in the Technical Rules, as dated in the Annex, on the basis of the operating permits issued under Sec. 7 of the German Atomic Energy Act. The introduction of the Single European Market and the adoption of European directives in the field of equipment safety have influenced, and will continue to influence, the national legislative structure. Changes affecting convoy-type nuclear power plants can be found in the applicable laws and directives, such as the Atomic Energy Act, the Industrial Code, and in new regulations, such as the Equipment Safety Act with its associated ordinances, and the applicable engineered safeguards rules, such as KTA, AD, VdTUeV, VDI. Moreover, the generally recognized state of the art as laid down in DIN, SEL, SEW publications is subject to permanent European harmonization and, consequently, comprehensive national reorganization. These boundary conditions can be upheld only if the specifications about the advancing state of the art specified in the operating permits are put into effect painstakingly. The profile of requirements contained in these specifications must be aligned to the new situation in Germany (dominated by Europe) with the licensing authority and the competent expert consultant within the supervisory procedure for operation under the Atomic Energy Act. The situation described here for the modern convoy-type nuclear power plants must be extrapolated also to older nuclear power plants, albeit subject to a supplementary adaptation to the respective licensing situation.

    Full Text Available El desembre de 1911 aparegué a la premsa local de Vic un article que va aixecar molta polseguera entre els bibliòfils de tot Catalunya. Un mossèn –historiador de l’art i gran moralistaacusava un conegut editor de llibres de bibliofília –sense dir-ne el nom-, d’editar llibres luxosos de contingut priàpic (pornogràfic. Aquest fet anecdòtic ens serveix per saber qui era l’editor esmentat, què hi havia de cert en l’»acusació» i com va encaixar el vituperat veure’s exposat a la vergonya pública. La correspondència creuada entre els dos protagonistes, exclusivament per mitjà d’un amic comú, ens facilita l’anàlisi de l’argumentari de l’un i de l’altre. Això ens permet copsar com s’entenia, des de la moral més conservadora a la d’un moderat lliurepensament, l’ampli arc que va de la literatura de temàtica amorosa a les obres clarament pornogràfiques. In December 1911 appeared in the local press in Vic (a town near Barcelona an article that raised an uproar in the bibliophile circles all over Catalonia. A priest (an Art historian and great moralist accused a well-known editor of fine books, without naming him, of editing luxury books of pornographic content. This anecdote serves us to find out who this editor was, how much truth there was in the «accusation» and how the censored editor took the fact of being exposed to public shame. The correspondence between the priest and the editor, facilitated by a common friend, helps us analyze the arguments of both parties. We can grasp how the vast frame that embraces love literature to clearly pornographic works was perceived, both from the most conservative moral to a moderate free-thinking perspective.

    The first part of the study deals with questions concerning radiation on account of the release of radioactive substances into the environment via the aquatic pathway. The discussion is preceded by a lecture on the basis for the calculations, and on a lecture on the results of primary radiological model calculations. The colloquium aims at establishing existing knowledge, at coordinating deviating opinions, and at elaborating questions still open and the possibility to deal with these. On the whole, ten questions have emerged. They are mainly concerned with site conditions. These questions will be dealt with in the form of partial studies by individual participants or by task groups. The results will be discussed at further colloquia. (orig.) [de

    The second part of the study deals with questions concerning the release of radioactive substances into the environment via the air pathway and their diffusion. On the basis of an introductory lecture on basic principles the interrelations within the whole complex to be considered are discussed. For the release itself, the fundamental issues concerning type and quantity of radioactive substances and their time behaviour are established. With regard to diffusion, calculation models and their parameters are reviewed. Much the same as the first colloquium, this one too aims at compiling existing models and data, determining the known facts and the questions still open and formulating tasks for the further activities. Thirteen questions emerged. They are concerned, above all, with the existing conditions for release and diffusion at the site. These questions will be dealt with in the forms of partial studies by individual participants or by task groups. Results will be reported on at further colloquia. (orig.) [de

    The 'Kernkraftwerk Niederamt AG' (KKN) Company submitted to the Swiss Federal Inspectorate of Nuclear Safety (ENSI) a request for a general license for a new power plant to be built near to the Goesgen power plant. According to the law, all damage risks with a probability higher than 10{sup -4}/a must be taken into account through protection measures. The considered risks concern the power plant itself as well as the population in the neighbourhood and the environment. The purpose of the general license is to demonstrate that the site chosen for the foreseen power plant is acceptable and that the risks can be counteracted through adequate measures. The buildings of the power plant and their partition over the two banks of the Aare River are briefly described. The reactor is a Light Water Reactor of third generation with a maximum thermal power of 5.8 GW{sub th}. The main cooling is provided by a hybrid system of water evaporation and air heating, what reduces the plume at the exit of the cooling tower. First, it is demonstrated that, in the case of a very unlikely severe accident in the power plant, the people in the neighbourhood can be evacuated quickly. Then, numerous types of possible accidents in the neighbourhood of the power plant are analyzed in order to settle their possible negative influence on the operation of the power plant: bursting of gas containers on the neighbouring roads and railways, fires of all types of hydrocarbons, air pollution through chloride gas, etc. The check by ENSI of the KKN studies on the potential danger for the power plant through neighbouring industrial plants, roads or railways demonstrated that none of the considered accidents presents an unacceptable risk for the power plant: on the one hand, these plants are located too far from the power plant, so that a sensible injury to the power plant safety can be excluded; on the other, the protection of the power plant can be guaranteed through appropriate technical

    For the German risk evaluation study, analogous to the Rasmussen report (WASH--1400), embarked upon in June 1976, the Kernkraftwerk Biblis B serves as the plant of reference. The first interim results are available for various sub-headings of the study. The main finding seems to be the decisive importance of the containment in limiting the accident consequences even in those cases where, on account of postulated failure of safety systems, the melt down of the reactor core is to be expected.

    D1-Simulator is operated by Kraftwerks-Simulator-Gesellschaft (KSG) and Gesellschaft f?r Simulatorschulung (GfS) at the Simulator Centre in Essen since 1977. The full-scope control room training simulator, used for Kernkraftwerk Biblis (KWB) is based on a PDP-11 hardware platform and is mainly programmed in ASSEMBLER language. The Simulator has reached a continuous high availability of operation throughout the years due to specialized hardware and software support from KSG maintenance team. Nevertheless, D1-Simulator largely reveals limitations with respect to computer capacity and spares and suffers progressively from the non-availability of hardware replacement materials. In order to ensure long term maintainability within the framework of the consensus on nuclear energy, a 2-years refurbishing program has been launched by KWB focusing on quality and budgetary aspects. The so-called D1+ Simulator project is based on the re-use of validated data from existing simulators. Allowing for flexible project management methods, the project outlines a cost and risk optimized approach to Nuclear Power Plant (NPP) Simulator modernization. D1+ Simulator is being built by KSG/GfS in close collaboration with KWB and the simulator vendor THALES by re-using a modern hardware and software development environment from D56-Simulator, used by Kernkraftwerk Obrigheim (KWO) before its decommissioning in 2005. The Simulator project, launched in 2004, is expected to be completed by end of 2006. (author)

    On March 17, 2005, the Baden-Wuerttemberg State Ministry of Economics, following instructions by the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU), imposed an ex-post-facto condition on the licensee of the Philippsburg Units 1 and 2 nuclear power station. Its content can be summed up as follows: In case of deviations from criteria specified in the license which are relevant to accident management, the plant must be shut down. In case of suspicion that, for whatever reason, accident management could be doubtful, accident management must be demonstrated to function; failing this, the plant must be shut down. In a decision of February 26, 2007, the Baden-Wuerttemberg State Court of Administration set this condition aside. The Federal Administrative Court, in its ruling of April 10, 2008, essentially confirmed the decision of the court of first instance. Both decisions are analyzed. Licensees and public authorities are shown the general framework of administrative law within which their relations are regulated. Another subject covered is jurisdiction about provisions against damage in connection with the ruling of the Federal Administrative Court of April 10, 2008 in the matter of the Brunsbuettel interim store. The court comments on the question of provision against damage in the area of protection, develops the dogma from scratch again as to the borderlines separating provisions against damage from residual risk and, within this framework, addresses the problem of third-party action against execution, especially so with respect to protection. The question of possible repercussions upon practice is discussed also for this court ruling. (orig.)

    As a consequence of the INSAG-4 report on `safety culture`, published by the IAEA in 1991, the Federal Commission for the Safety of Nuclear Power Plants (KSA) decided to hold a one-day seminar as a first step in this field. The KSA is an advisory body of the Federal Government and the Federal Department of Transport and Energy (EVED). It comments on applications for licenses, observes the operation of nuclear power plants, assists with the preparation of regulations, monitors the progress of research in the field of nuclear safety, and makes proposals for research tasks. The objective of this seminar was to familiarise the participants with the principles of `safety culture`, with the experiences made in Switzerland and abroad with existing concepts, as well as to eliminate existing prejudices. The main points dealt with at this seminar were: - safety culture from the point of view of operators, - safety culture from the point of view of the authorities, - safety culture: collaboration between power plants, the authorities and research organisations, - trends and developments in the field of safety culture. Invitations to attend this seminar were extended to the management boards of companies operating Swiss nuclear power plants, and to representatives of the Swiss authorities responsible for the safety of nuclear power plants. All these organisations were represented by a large number of executive and specialist staff. We would like to express our sincerest thanks to the Head of the Federal Department of Transport and Energy for his kind patronage of this seminar. (author) figs., tabs., refs.

    The electrical design of nuclear power plants and the reliability of their electrical power supply including the offsite power supply are of high importance for the safe operation of the plants. The operating experience of recent years has shown that disturbances in the external grid can have impact on the electrical equipment of nuclear power plants. In the course of this project, possible causes and types of grid disturbances were identified. Based on these, scenarios of grid disturbances were developed. In order to investigate the impact of the developed scenarios of grid disturbances on the electrical equipment of nuclear power plants, the auxiliary power supply of a German pressurized water reactor of type Konvoi was simulated using the simulation tool NEPLAN. On the basis of the results of the analyses, it was identified whether there are possible measures to prevent the spread of grid disturbances in the plants which have not been implemented in the nuclear power plants today.

  16. On the safety of French nuclear power plants. Zur Sicherheit der franzoesischen Kernkraftwerke

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

  17. Consequences of the Federal Administrative Court decisions about the Biblis on-site interim store and the 'Biblis condition' as seen by the Nuclear Regulatory Authority of the State of Baden-Wuerttemberg

    On March 17, 2005, the Baden-Wuerttemberg State Ministry of Economics, following instructions by the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU), imposed an ex-post-facto condition on the licensee of the Philippsburg Units 1 and 2 nuclear power station. Its content can be summed up as follows: In case of deviations from criteria specified in the license which are relevant to accident management, the plant must be shut down. In case of suspicion that, for whatever reason, accident management could be doubtful, accident management must be demonstrated to function; failing this, the plant must be shut down. In a decision of February 26, 2007, the Baden-Wuerttemberg State Court of Administration set this condition aside. The Federal Administrative Court, in its ruling of April 10, 2008, essentially confirmed the decision of the court of first instance. Both decisions are analyzed. Licensees and public authorities are shown the general framework of administrative law within which their relations are regulated. Another subject covered is jurisdiction about provisions against damage in connection with the ruling of the Federal Administrative Court of April 10, 2008 in the matter of the Brunsbuettel interim store. The court comments on the question of provision against damage in the area of protection, develops the dogma from scratch again as to the borderlines separating provisions against damage from residual risk and, within this framework, addresses the problem of third-party action against execution, especially so with respect to protection. The question of possible repercussions upon practice is discussed also for this court ruling. (orig.)

    The largest portions of the whole-body dose in the radiation exposure pathway waste water are provided by the pathways fish and sedimentary stay. The gastro-intestinal and bone dose result exclusively from the fish pathway. To the thyroid dose the pathways drinking-water, fish and spray irrigation/vegetables contribute as equal shares. The main dose stems, for as much as 97%, from the sedimentary stay. The most important nuclides are P-32 and J-131. The most important nuclides of the waste air pathway are C-14 (whole-body and bone dose) and J-131 (thyroid dose). The development of the calculation models reveals no errors inherent to the system or dependence on the user. (DG) [de

    This working paper contains all the materials developed for and used in the field test of 'Student Attitudes toward Atomic Power Stations'. This research is a component of a larger project called 'Attitudes and Attitudes Change with Regard to Problems of Energy Supply and their Consequences for our Environment'. A central aim of this project is the development of instrumental strategies enabling the student to build up in this field a critically reflective and active behavior and attitudes based on sound problem consciousness. These instrumental strategies are derived from theories of social, learning and environmental psychology. A concrete result of these efforts are the materials of the field test mentioned above. They include: a) The draft of an instructional unit 'Atomic Power Stations - Prosperity or Disaster' with - a booklet on the subject matter for students and teachers - a paper on the contents of the instructional unit and their sequence - information for the students concerning the aims of the investigation - working materials for the students - reading materials for the teachers informing them about the proposed instructional strategies based on the psychological theories: (1) model-learning and the structuring of knowledge, (2) how to activate and motivate students, (3) the stabilization of attitudes and (4) small group work. b) Instruments for testing and observation. These instruments were used within a criterion-oriented evaluation and for a test of the effects of the different proposed items used in the instruction.

    Analyses are performed for three accident scenarios postulated to occur in the Goesgen Nuclear Power Plant, a 900 MWe Pressurised Water Reactor of Siemens design. The scenarios investigated comprise a Station Blackout and two separate cases of small break loss-of-coolant accident which lead, respectively, to high, intermediate and low pressure conditions in the reactor system. In each case the accident assumptions are highly pessimistic, so that the sequences span a large range of plant states and a damage phenomena. Thus the plant is evaluated for a diversity of potential safety challenges. A suite of analysis tools are used to examine the reactor coolant system response, the core heat-up, melting, fission product release from the reactor system, the transport and chemical behaviour of those fission products in the containment building, and the release of radioactivity (source term) to the environment. Comparison with reference values used by the licensing authority shows that the use of modern analysis tools and current knowledge can provide substantial reduction in the estimated source term. Of particular interest are insights gained from the analyses which indicate opportunities for operators to reduce or forestall the release. (author)

    Based on the event tree analysis as documented in the Appendix 1, the failure probabilities of the system functions required to control the initiating events are evaluated in this Appendix 2. The reliability investigations necessary for the evaluation of the event sequences are performed mostly by means of the fault tree analysis. The methods of the reliability analysis, the composition and function of the systems important to safety and the functional tests performed on these systems are dealt with in detail. The comprehensive documentation of the reliability analyses as performed for the internal events necessitated a division of this Appendix 2 into two volumes.

    The advanced handbook of safety analyses (HSA) comprises a comprehensive electronic collection of knowledge for the compilation and conduction of safety analyses in the area of reactor, plant and containment behaviour as well as results of existing safety analyses (performed by GRS in the past) with characteristic specifications and further background information. In addition, know-how from the analysis software development and validation process is presented and relevant rules and regulations with regard to safety demonstration are provided. The HSA comprehensively covers the topic thermo-hydraulic safety analyses (except natural hazards, man-made hazards and malicious acts) for German pressurized and boiling water reactors for power and non-power operational states. In principle, the structure of the HSA-content represents the analytical approach utilized by safety analyses and applying the knowledge from safety analyses to technical support services. On the basis of a multilevel preparation of information to the topics ''compilation of safety analyses'', ''compilation of data bases'', ''assessment of safety analyses'', ''performed safety analyses'', ''rules and regulation'' and ''ATHLET-validation'' the HSA addresses users with different background, allowing them to enter the HSA at different levels. Moreover, the HSA serves as a reference book, which is designed future-oriented, freely configurable related to the content, completely integrated into the GRS internal portal and prepared to be used by a growing user group.

    Acting on behalf of Energiewerke Nord GmbH Lubmin, Anlagen- und Kraftwerksrohrleitungsbau Greifswald GmbH (AKB) planned and built a station for disassembly of the activated annular water tank (RWB) of the decommissioned Rheinsberg nuclear power plant. As part of this demolition step, the annular water tank must be conditioned and disposed of as a component of the reactor facility. This required planning, manufacturing, testing and construction on site of suitable disassembly and handling techniques and the necessary plant and equipment. The client opted for disassembly by means of a diamond cable saw for conditioning the annular water tank into segments fit for shipping, and defined the basic components for the disassembly station in a specification of deliveries and services. The disassembly station serves to divide the annular water tank by means of diamond cable saws into 2 sections in such a way that segment pieces for transport are produced. The existing activation of the annular water tank also entailed the need to plan for the shortest possible time to be spent on handling near the annular water tank, providing radiological protection to the personnel, and performing the sawing steps from a separate operating console assisted by camera surveillance. After works acceptance tests at the manufacturer's, AKB, in October 2009 and February 2010, the disassembly station was delivered to the customer at Rheinsberg KKR free from defects in June 2010.

  4. Harmonisation of licensing processes for decommissioning. Options and limitations; Genehmigungsverfahren fuer die Stilllegung der deutschen Kernkraftwerke. Konvoi oder Kakophonie?

    The shutdown of eight reactors in Germany in the wake of Fukushima 2011 and the scheduled phase-out of the remaining units in several steps ending 2022 has obviously triggered a wave of applications for decommissioning and dismantling licences. It would seem natural to strive for a harmonised handling of these processes, analogous to the 'convoi' concept which was successfully employed for licensing and construction of the three most recent German NPPs in the 1980s. However, a comparative analysis shows that the motivation of all players is much different from that of earlier times and that harmonisation of licensing processes for dismantling is not as crucial for operators, authorities and technical support organisations as it was for construction.

    The reactor accident in Fukushima, Japan, in 2011 triggered a thorough review of the off-site emergency preparedness and response for nuclear power plants in Germany. ''Off-site emergency preparedness and response'' includes all actions to protect the public outside the fence of a nuclear power plant. This review resulted in several changes in off-site emergency preparedness and response, which are briefly described in this article. Additionally, several recent activities are described which may influence emergency preparedness and response in the future.

    After the extremely successful use of the multi-purpose lifting device and the reactor pressure vessel sealing head for the Brokdorf nuclear power plant, supplied by Siempelkamp Nukleartechnik in 2008 and 2009, a further contract was received in early 2010. E.ON Kernkraft decided to also order a multi-purpose lifting device each for the power plants at Grafenrheinfeld and Unterweser from Siempelkamp. The important innovation of the Siempelkamp multi-purpose lifting device is that it is manufactured entirely from austenitic steel. This allows it to remain in its storage location on the retracted upper core grid (UCG) in the flooded reactor pool during the unloading of the fuel elements, while the fuel elements are being changed. The advantage here for the operator is that the fuel elements change is shortened even further, and this reduces costs. Saving time is also an important requirement for the RPV sealing head. For the Brokdorf nuclear power plant, Siempelkamp manufactured and supplied the RPV sealing head. A precondition of this order was a total realisation time of seven months and to save valuable time during the outage for the operating company. With a new sealing concept, a further innovation from Siempelkamp came to bear on this contract. It makes it possible to safely handle the RPV sealing head using the multi-purpose lifting device.

    The report is aimed to discuss the implications of changed NPP lifetimes in Germany on energy policy, environment, energy cost and macroeconomics. An extensive scenario analysis is used considering the effects on the German energy system in the frame of the European context. It is shown that a nuclear phase-out until 2017 is technically feasible, but needs adequate replacement options that will change the German energy system in the medium term. The study shows that the time of nuclear phase-out has no significant influence on the use of renewable energies.

    The NPP Lingen (KWL) was shut-down in 1977. Due to the fact that no final repository was available the safe entombment for 25 years was chosen following the decommissioning. The conventional plant components were dismantled and removed from the plant site. The licensing procedure for reactor dismantling with final disposal in Schacht Konrad has been started. The beginning of dismantling operation is scheduled for 2013. The authors describe the preparatory work, the boundary conditions for the dismantling, radiation protection considerations with respect to manual demolition work after the rather long decay time.

    Due to the ultrasonic findings in the reactor pressure vessel of NPP Beznau-1 in 2015 the licensee had to provide a new structural integrity analysis based on the changed material properties. The authors discuss the interpretation of the findings in Beznau with in relation to similar findings in the Belgian NPPS Doel-3 and Tihange-2. A doubtless metallurgical characterization of the irregularities in the RPV wall as not possible based on ultrasonic testing only. Destructive testing of samples from the reactor pressure vessel is also not possible since no original material bearing irregularities is available.

    After full replacement of the feedwater pipe system during the inspection period in 1997, combined with a modern materials, manufacturing and analysis concept, the entire pipe system of the water/steam cycle in the reactor building of KKP 1 now consists of high-toughness materials. The safety level of the entire plant has been increased by leaving aside postulation of F2 breaks in the reactor building and providing for protection against 0.1 leaks. Based on fluid-dynamic calculations for the cases of pump failure and pipe break, as well as pipe system calculations in 5 extensive calculation cycles, about 130 documents were filed for inspection and approval (excluding preliminary test documents on restraints). Points of main interest for safety analysis in this context were the optimised closing performance of the 3rd check valves and the integrity of the nozzle region at the RPV. (oirg./CB) [Deutsch] Durch den Restaustausch der Speisewasserleitungen in der Revision 1997, verbunden mit einem modernen Werkstoff-, Fertigungs- und Nachweiskonzept, sind im Reaktorgebaeude von KKP 1 in den Hauptleitungen des Wasser-Dampf-Kreislaufes nur noch hochzaehe Werkstoffe eingesetzt. Durch den Verzicht auf das Postulat von 2F-Bruechen im Reaktorgebaeude und durch die Auslegung gegen 0,1F-Lecks wird das Sicherheitsniveau der Anlage insgesamt gesteigert. Ausgehend von fluiddynamischen Berechnungen fuer Pumpenausfall und Rohrbruch sowie Rohrsystem-Berechnungen in 5 umfangreichen Berechnungskreisen wurden fuer die Genehmigung und Begutachtung ca. 130 Unterlagen (ohne Halterungs-Vorpruefunterlagen) eingereicht und vom Gutachter geprueft. Schwerpunkte der Nachweisfuehrung waren die Optimierung des Schliessverhaltens der 3. Rueckschlagarmaturen sowie der Integritaetsnachweis des RDB-Anschlusses. (orig./MM)

    The paper describes the successful implementation of the restoration of water distribution channels at the cooling tower of the Emsland nuclear power plant under the aspect of ageing management. The main challenge of ageing management is the determination of potential ageing mechanism and to avoid systematically and effectively their damaging influences. In the course of the annual site inspections, abnormalities at the lower side of the water-distribution channels of the cooling tower were detected, analysed, and repaired. The procedures conserve the load bearing reinforcement only for a certain period. Therefore permanent structural monitoring is needed. (orig.)

    The present paper describes the successful implementation of the restoration of water-distribution channels at the cooling tower of the Emsland nuclear power plant under the aspect of ageing management. The main challenge of aging management is the determination of potential aging mechanism and to avoid systematically and effectively their damaging influences. In the course of the annual site inspections abnormalities at the lower side of the water-distribution channels of the cooling tower were detected, analysed, and repaired. The extraordinary high chlorine equivalent of the cooling water was identified as main reason of the damages located. Due to extensive infiltration into the concrete structure, chloride-induced corrosion generates a volume expansion of the reinforcement and thereby to a blast off of the concrete covering. According to the restoration concept, the damaged concrete was removed by maximum pressure water jet blasting; where necessary the reinforcement was retrofitted and a layered concrete substitution was applied by synthetic cement mortar. The realised procedures conserve the load bearing reinforcement only for a certain period, because the permanent chloride infiltration could not be stopped. Therefore, the structure has to be monitored permanently. (orig.)

    In 2005 the asbestos cement cooling tower packing was replaced by plastic material. Two years later, the packing showed strong deformations, deposits of solids and weight gain. At the end of 2007 parts of the packing collapsed into the cooling tower basin. Investigations were made, revealing that the thickness of the packing foil was too low and that packing geometry and biofilms on the surface of the packing favoured deposition of solids. Successful measures were taken to solve the problems. (orig.)

    The Goesgen nuclear power plant (KKG) received its operational licence on September 9, 1978. The operational start-up of the plant went on into the year 1979, but there was a short interruption because of the accident in the Three Mile Island reactor on March 28, 1979. In May 1985 KKG submitted a request for raising the thermal reactor power from the then 2808 MW to 3002 MW. Based on the examination by the Federal Agency for the Safety of Nuclear Installations (HSK), the Swiss Federal Council granted the licence in two steps: in December 1985 for raising the thermal power to 2900 MW, and, in April 1992, to 3002 MW. The licence for the second step was given under the condition that some more experience was to be gained concerning the fuel rod cladding under higher loading. As part of the yearly re-licensing on restart after fuel assembly reloading, HSK confirmed that the plant status conformed to the legal requirements. In November 1986, HSK asked all Swiss nuclear power plant managers to state their opinions on proposed measures concerning severe accidents. Some of the measures were already in discussion; the Chernobyl accident on April 26, 1986, accelerated their implementation and was also a reason for the introduction of the measures against severe accidents. In this context, KKG carried out a risk study which led to the installation of a filtered pressure release system for the containment. Another consequence of the Chernobyl accident was the introduction of technical Periodical Safety Reviews (PSR) for all operating nuclear power plants. Central points of the PSR are: a) comparison with the continuously improving state-of-the-art of science and technology concerning safety precautions; b) a systematic evaluation of operating experience and plant status; c) the taking into account of probabilistic safety analyses in the overall evaluation of the plant. Within the framework of the examination of the overall plant, HSK also checks how its requirements concerning plant safety and radiation protection are taken into account. Even if the plant manager considers the guarantee of plant safety as his duty, an overall investigation by the authorities makes sense because it also looks into rare accident scenarios for which there are, of course, no actual working experience and which can only be considered within the framework of extended plant examinations. The PSRs on the Swiss nuclear power plants therefore complement the continuous control activities of the HSK; they are carried out about every 10 years. For KKG the PSR process was initiated by a letter from the HSK in February 1994. The areas to be considered were: a) examination of design and fulfilment of technical safety systems and comparison with the actual state-of-the-art of science and technology; b) evaluation of operational experience; c) review of the technical precautions against severe accidents including the preparation of emergency measures; d) review of the emergency organisation; e) examination of the plant protection against radioactivity; f) future dismantling at the end of operational life and disposal of the radioactive wastes; g) evaluation of accident analyses and of the KKG probabilistic safety analysis; h) review of plant organisation and plant management. The examination confirmed that, at KKG, there are very many technical safety precautions. KKG operational experience is good, the results show a high degree of operational availability and a very low number of incidental shut-downs. In international comparison the collective doses of the staff are low and the release of radioactive materials to the environment is negligible; on this account KKG is one of the world's best plants operating pressurised water reactors. Up to now the examinations have not brought any ageing deterioration to light concerning the status of safety-relevant components or ducts

    Eating contaminated animal food represents a considerable contribution to human irradiation loading from radioactive emission. When estimating the irradiation loading, a precondition is a knowledge of the radio-nuclide transfer from the feedstuff into the meat of the domestic animal. The radio-ecology importance of this exposure path requires a precise examination of the origin of the values given by SSK with the data in the international literature. The transfer of radio-cesium, radio-strontium, radio-iodine and plutonium from feedstuff into meat/milk are especially considered.

    Nuclear power plant companies make efforts to enhance the operational safety in the plant. Despite a variety of measures the number of accidents at work is still too high, esp. for external personnel. Social psychological considerations were used to develop communication tools for the elimination of hazardous situations, for instance by safety dialogues between employees. The observation of hazardous situations should trigger communication and discussion on the risk of the specific situation. In the contribution practical experiences and recommendations for the realization of a safety dialogue culture in the NPP Grafenrheinfeld are summarized and illustrated by examples.

    An emergency decision support system for accidental releases of radioactivity into the atmosphere providing regional wind field information is presented. This system is based on intensive meteorological field campaigns each lasting 3-4 months in the regions around the Swiss nuclear power plants. The wind data from temporary and permanent stations are analysed to evaluate the typical wind field patterns occurring in these regions. A cluster analysis for these data-sets lead to 12 different wind field classes with a high separation quality. In the present report, it is demonstrated that an on-line acquisition of meteorological data from existing permanent stations is enough to diagnose the recent wind field class in a region with a radius of 25 km around the nuclear power station of Goesgen with a probability of 95% to hit the correct class. Furthermore, a method is presented to use a high resolution weather prediction model to forecast the future wind field classes. An average probability of 76% to hit the correct class for a forecast time of 24 hours is evaluated. Finally, a method for parameterization of turbulence providing input for dispersion models from standard meteorological online data is presented. (author)

  6. Safety technical considerations on the 2012 periodic safety verification of the Beznau nuclear power plant; Sicherheitstechnische Stellungnahme zur Periodischen Sicherheitsüberprüfung 2012 des Kernkraftwerks Beznau

    According to nuclear legislation, the owner of an operational license for a nuclear power plant has to provide a periodic safety verification (PSU) every 10 years. The 'North Eastern Power Plants' company (NOK), today AXPO Power AG already performed such a PSU for the Beznau-2 nuclear reactor block (KKB2) in 2002. The Beznau-1 nuclear reactor block (KKB1) received its definitive operational license in October 1970, after test operation during 7 months. After the license for test operation received on July 16{sup th}, 1971, the operational license of KKB2 was renewed several times, each time for a certain period of validity. In 1991, NOK requested a definitive operational license for KKB2, but in 1994 the Swiss Federal Council lengthened the license for only 10 years. Moreover, it laid down that NOK has to periodically report on the safety of the facility. With its letter of August 23{sup rd}, 1998, the Federal Office of Energy defined the documents to be produced for the PSU. The extent of the PSU was defined in such a way that many documents concern the whole power plant, i.e. both nuclear reactor blocks. On December 3{sup rd}, 2004, the Swiss Federal Council granted KKB2 an operational license of limited validity. The present report reviews the 2012 PSU, which covers the time interval from January 1{sup st}, 2002, to December 31{sup st}, 2011, from the point of view of safety. It contains documents for the evaluation of both reactor blocks at KKB. The Beznau interim storage pool was also taken into consideration; it is situated on the KKB site, but, according to a decision of the Swiss Federal Council of May 23{sup rd}, 1991, it has an independent operational license. The evaluation of ageing surveillance takes the whole operational period of the facility into account, i.e. the ageing mechanisms acting as from the beginning of the operation. Moreover, important developments that occurred after the surveillance time interval have been taken into account, especially the status of the examination of the defects discovered during the revision shutdown in 2015 concerning the material of the reactor pressure vessel of block 1. As far as the NOK’s request for an unlimited operational license is concerned, NOK has to prove in time, before the 40-year license limit is up, that the design boundaries of safety-relevant components will not be reached during the duration of extended operation. Otherwise, the necessary refit works have to be performed in time. KKB has produced the requested proof for the long-term operation of both blocks. The results of the supervisory work carried out by the Swiss Federal Nuclear Safety Inspectorate (ENSI) were published in the safety technical review for KKB1 and KKB2. ENSI concludes that there are no safety technical objections against the operation of both blocks beyond the limit of 40 years. On the basis of the state of knowledge when the considerations were made, the criteria for shutting down will not be reached in the 10 following operational years, neither by KKB1 nor by KKB2.

    The recurrent safety inspection is intended as an inspection supplementing the continuous operation monitoring activities within the framework given by the supervisory activities of the supervisory authority. The first recurrent safety inspection is scheduled to be performed about ten years after start-up of the plant, with subsequent inspection intervals to cover ten-year periods, and recorded operating and monitoring results to be taken into account at each recurrent inspection. The purpose of the recurrent safety inspections is to ascertain that post-inspection operation of the plant meets the then required safety standards. Significant testing results of the latest inspection are to be analysed and compared with regard to the current state of the art and operating results accumulated since the previous inspection, for subsequent definition of enhancements if required.

    The nuclear power plant operators have to bear the costs associated with the closure and the decommissioning of the German nuclear power plants as well as the costs for the disposal of nuclear waste. For that purpose, the operators have to build up sufficient reserves for the decommissioning phase. These reserves at the end of 2013 amounted to approximately 36 billion Euro. Changing this system is discussed very so often. Last in May 2014, a public debate started dealing with the so called trust model (''Stiftungsmodell''). The press published deliberations of several operators to transfer their entire nuclear business to the Federal Republic of Germany. Under this deliberation the current nuclear power plant operations, as well as closure obligations would be contributed to trust. Further, also the reserves should be ''transferred'' to the trust. RAG-Foundation (RAG-Stiftung) - which will assume the financial obligations in connection with Germany's closure of underground coal mining activities - sometimes is cited as a role model. The article covers elements of German trust law and atomic energy law regarding such deliberations. In trust law e.g. it can be debated whether the trust should be established under public or - as in the case of RAG-Foundation - under private law. In this context we will set out the major differences between those two options. In the public law part we will notably address issues arising from individual licensing requirements for nuclear power plants and focus on questions concerning reliability, requisite qualification and organizational structures.

    On July 31, 1992, the nuclear power plant Leibstadt AG (KKL) submitted a request for a modification of its operation license for increasing the reactor thermal power to 3600 MW. In its examination, the Federal Agency for the Safety of Nuclear Installations (HSK) investigated the effects of the power increase on reactor safety, especially on the safety criteria which can limit the power. In doing this, a distinction has to be made between normal operation, design incidents and out-of-design accidents. KKL is a boiling water reactor (BWR) with a current maximum thermal power of 3,138 MW with 648 fuel assemblies in the core. Since the start of operation in February 1984, the reactor has been continuously improved and now almost fulfils the present state-of-the-art of science and technology for BWRs. After some incidents during the early years, the plant shows a high level of availability. During the past 6 years some fuel assembly damage has cast a shadow on good operational experience, but until now the collective irradiation dose of the plant staff and the environment has remained mostly below legal limits, as well as for the release of radioactive materials to the atmosphere and to the Rhine River. Calculations of core loading with the fuel assemblies presently used at KKL have shown that the operation and safety limits of the reactor core can still be preserved with a thermal power of 3600 MW. For normal operation, no objection can be raised against the power increase. This increase, however, has to be carried out step-by-step in order to gain experience concerning plant behaviour. With the higher power rating, increased dose rates are expected on systems and components, in plant rooms and in the plant area, which also leads to increased dose rates to the staff and environment. This increase has to be estimated and, possibly, correction measures will have to be taken in order to reduce them. Especially to be monitored is the dose rate increase in the machine hall. In the case of design incidents too, all safety-relevant limits and the maximal tolerable dose rates in the environment must be respected. In the context of design incidents, the 'transitory' group also constitutes the limiting case with the higher power. For the complete judgement of the safety of a nuclear power plant it is not sufficient to estimate the effects of a design incident through deterministic methods. The evaluation of the effects of out-of-design accidents needs a probabilistic safety analysis which determines the frequency as well as the consequences of an accident. The results show that KKL represents a very small risk for the environment. In KKL the measures necessary for safe operation and protection of mankind and environment at a thermal power of 3600 MW have already been taken or will be taken shortly. According to its examination, HSK concludes that there are no safety-relevant reasons speaking against an operational license for the increased thermal power. The increase will, however, have to be carried out in 4 steps of 1 year each in order to gain operational experience

    Extending the life of the nuclear power plants currently operated in Germany is being discussed in the light of a more likely change in government for a Christian Democrat/Liberal coalition. The reason cited most frequently is the impossibility to meet the objectives of climate protection without raising further the price of electricity if the life of nuclear power plants cannot be extended. The question to be looked into is that of the legal pre-requisites to be established in Germany in order for the existing nuclear power plants to be operated for longer periods of time. So in this contribution some discussion is done wether a possible lifetime extension of nuclear power plants will react on power prices.(GL)

    The catalogue of requirements for a plant-specific safety inspection of German nuclear power plants taking into account the Fukushima-I (Japan) events worked out by the German RSK (reactor safety commission) includes the following inspection topics: natural events like earth quakes, floods, weather-based consequences and possible superposition; civilization-based events like airplane crash, gas release, reactor accident consequences for neighboring units, terroristic impacts, external attacks on computer-based control systems. Further event-independent assumptions have to be considered: station blackout, long-term emergency power supply requirement, failure of auxiliary cooling water supply, efficacy of preventive measures, aggravating boundary conditions for the performance of emergency measures.

    The transport and storage cask CASTOR {sup registered} 1000/19 was designed for a dry interim storage of 19 spent fuel elements of WWER-1000 reactors. The project performed by GNS mbH included design, manufacture, licensing and delivery of 36 casks. The specific requirements for NPP Temelin concern loading and dispatch of the casks to be performed during the outage period of the reactor, thus high reliability and functionality of the casks and the manipulation equipment. The paper describes the mechanical design of the cask, stress analyses for a hypothetical fall accident from 9 m height, performed using the FEM program ANSYS and LS-DYNA. The 3D simulation models are based on conservative material characteristics and upper-bound boundary conditions. The safety analysis was performed using qualified software programs validated by the Czech authorities.

    The measurements and statistics, which were much more detailed than the annual routine measurements, included /sup 131/I emission measurements on the stack, the registration of meteorological parameters, measurements of /sup 131/I concentrations in air, grass, and milk, and supplementary statistics on the farmers' animal keeping habits. The infant thyroid dose resulting from /sup 131/I in milk was found to be lower by at least one order of magnitude than the value calculated from the emission data for the point of maximum exposure according to the Guideline to Explain Sect. 45 StrlSchV. This result confirms the results of earlier investigations. The model calculation according to the Guideline yields a value of 30 mrem for incorporation of /sup 131/I into the infant thyroid via the ingestion pathway for the year 1980, i.e. 25 times the measured value. The possible reasons for this are discussed.

    The safety of nuclear power plants is determined largely by the integrity of the internally pressurized coolant containment system. The highly radioactive materials (fission products) generated within this pressurized containment (primary system) in the reactor core during nuclear power plant operation constitute an extremely great potential hazard. Catastrophic failure of the primary system, and the release into the environment of the radioactive inventory, must be avoided at all costs. Because of the high coolant pressure and the high power density, pressurized water reactors (PWR) impose particularly strict requirements with respect to reactor safety. German nuclear power plants equipped with light water reactors enjoy the reputation of being among the safest plants in the world. This frequent statement is justified in the light of the research and development work performed jointly by industry, government agencies, science, and expert bodies between the 1960s and the 1990s. The research projects, which implied considerable financial expenditures, their internationally acknowledged results, and the resultant additional backfitting measures conducted in German nuclear power plants at many billions of expenditures, were hardly noticed by the German body politic.

    After a severe nuclear power station accident with release of radioactivity, some few persons in the neighbourhood of the station may accumulate a dose of more than 1 Sv. A lot of other people may be in doubt, whether they have received a radiation dose. Hospitals and practitioners may break down under the run on them by terrified persons, who have no or only small doses. In order to prevent this, 'assembly centers' should be run at the outer limit of the irradiated area. About 1'000 persons per day from the INNER, MIDDEL and OUTER irradiated regions should be informed and psychologically attended. A concept for such a 'assembly center' has been elaborated by members of the National Commission for AC-Protection, the Office for Protection of the Population, the National Alarm Center, the Swiss Inspectorate for the Safety of Nuclear Power Stations as well as public health officers. The concept has been tested in an exercise with 185 persons. (orig.)

Um eine moegliche Strahlendosis bei diesen Personen (aber auch bei solchen, die im Zweifel sind) zu ermitteln, sollen am Rande der betroffenen Region Informationsstellen mit orts- und ereignisbezogener (individueller) Personenbeurteilung sowie psychologischer Betreuung errichtet werden; denn die Einrichtungen des oeffentlichen Gesundheitswesens (Spitaeler) und die privaten Arztpraxen waeren nicht in der Lage, einen groesseren Ansturm von zu beratenden Personen zu bewaeltigen, die groesstenteils gar nicht gefaehrdet sein duerften. Diese sog. Kontakstellen sind keine generellen Dekontaminationsstellen, bieten keine generellen medizinische Dienste an und sind auch keine Auskunftszentren fuer die Medien. Rund 1'000 Personen sollen pro 24 Stunden auf einer Kontaktstelle betreut werden, wobei rund 500 Personen mit Dosen von weniger als 50 mSv (Gruppe D), rund 300 Personen mit Dosen zwischen 50 und 500 mSv (Gruppen C und B) und knapp 200 Personen mit Dosen ueber 500 mSv (Gruppe A) erwartet werden. Unter diesen 1'000 Personen duerfte es 30 schwangere Frauen (Gruppe E) haben. Mittels eines einfachen Leitsystems sollen die Ratsuchenden in die Gruppen A bis E eingeteilt werden.

    STRATEG is a 1:10 scale glass model of a PWR (Biblis B reactor coolant circuit) built by RWE in 1986 on the site of the Biblis plant as a training model. The model can be used for training of normal operation and incident situations since all important operating and incident sequences of a PWR can be simulated. Thermodynamic phenomena can also be demonstrated occurring under various operating situations and in particular associated with malfunctions. (Z.S.) 1 tab., 3 figs., 1 ref

    The nuclear power plant project at Kaiseraugst has been worked on for over 20 years. In 1985 the Swiss Parliament decided to license the plant. The cost of the work to date is about 1.2 x10 6 Swiss Franks. Continuation of the project is only sensible if it can be realized within a foreseeable space of time. It is probable that the discussions concerning future energy, environment and safety will continue for a long time. If this is clear that the Kaiseraugst project will not be realized during the next five to ten years for social, civic and political reasons. A continuation of the project is not justifiable. Kernkraftwerk Kaiseraugst AG must be adequately compensated. A motion has been presented to Parliament which charges the Government to negotiate with Kernkraftwerk Kaiseraugst AG for cancellation of the project

    The aim of the analyses on natural hazards described in this report was to evaluate the advantages of innovative hazard assessment methods available today over the hazard assessment methods commonly applied for German nuclear power plant sites in the past. For each hazard under consideration (earthquake, flooding, and wind loads) it has been assessed whether the new methods provide additional insights that could call for their mandatory application in future site specific hazard assessments. If no additional insights are gained, the hitherto applied methods can be considered adequate according to today's standards. In the context of this work, no areas could be identified where the hazard assessment methods stipulated in German (nuclear) regulations are generally inadequate. These methods that are commonly applied in practice do not seem to be prone to significantly underestimate the site specific hazard. Nevertheless, some newer methods allow for more precise (reduction of uncertainties) and more comprehensive (consideration of additional hazard characteristics) hazard assessments. Therefore, depending on the hazard under consideration, it could be advisable to supplement future site specific hazard assessments by some additional analyses. As the methods for some of these additional analyses are not yet fully developed, further research will be necessary to enable these amendments.

  6. Hybrid cooling tower Neckarwestheim 2 cooling function, emission, plume dispersion

    International Nuclear Information System (INIS)

    Braeuning, G.; Ernst, G.; Maeule, R.; Necker, P.

    1990-01-01

    The fan-assisted hybrid cooling tower of the 1300 MW power plant Gemeinschafts-Kernkraftwerk Neckarwestheim 2 was designed and constructed based on results from theoretical and experimental studies and experiences from a smaller prototype. The wet part acts in counterflow. The dry part is arranged above the wet part. Each part contains 44 fans. Special attention was payed to the ducts which mix the dry into the wet plume. The cooling function and state, mass flow and contents of the emission were measured. The dispersion of the plume in the atmosphere was observed. The central results are presented in this paper. The cooling function corresponds to the predictions. The content of drifted cooling water in the plume is extremely low. The high velocity of the plume in the exit causes an undisturbed flow into the atmosphere. The hybrid operation reduces visible plumes strongly, especially in warmer and drier ambient air

    With its decision of November 22, 1979 - BVerwG 4 B 162/79 -, the Federal Administration Court, at the expense of the plaintiff, has judged against a Bremen resident who had lodged a complained against the non-admission of an appeal in a partial verdict by the Lueneburg Higher Administrative Court concerning licenses under water law for Kernkraftwerk Unterweser. The value in litigation for the complaint procedure was set at DM 5000,-. In its partial verdict of February 12, 1979 - VII OVG A 113/77 - the Lueneburg Higher Administrative Court had decided that the plaintiff's rights are not infringed by the administrative steps under water law taken by the defendant district, and that pleas under nuclear law cannot be entered in the present procedure. The Federal Administrative Court was of the same opinion. The reasons for its decision are given in full wording. (orig./HP) 891 HP/orig.- 892 CKA [de

  10. German study on the risks of nuclear power plants

    Wollny, V.

    1987-01-01

    The 'Deutsche Risikostudie Kernkraftwerke', DRS, (German study on the risks of nuclear plants) calculates a frequency of 1/10000 years (i.e. once in 10000 years of reactor operation) for the event of insufficient cooling of the reactor core occurring. The resulting collective risk is put at approximately 10 deaths per year for 25 plants. As the explanations show, the error margin of such a risk statement is enormous. Moreover, much seems to indicate that the risk was underrated. Apart from this, risk analyses are of doubtful value in the decision process for or against the introduction of large-scale technologies. They cannot replace the individual decision of all concerned.

    Within its 5. Framework Programme, the EC is funding the project EVIDOS ('Evaluation of Individual Dosimetry in Mixed Neutron and Photon Radiation Fields'). The aim of this project is the optimisation of individual monitoring at workplaces of the nuclear fuel cycle with special regard to neutrons. Various dosemeters for mixed field application - passive and new electronic devices - are tested in selected workplace fields in nuclear installations in Europe. The fields are characterised using a series of spectrometers that provide the energy distribution of neutron fluence (Bonner spheres) and newly developed devices that provide the energy and directional distribution of the neutron fluence. Results from the first measurement campaign, carried out in simulated workplace fields (IRSN, Cadarache. France), and those of a second measurement campaign, carried out at workplaces at a boiling water reactor and at a storage cask with used fuel elements (Kernkraftwerk Kriimmel, Germany), are described.

  13. A current perspective on the risk significance of steam explosions

    International Nuclear Information System (INIS)

    Snyder, A.W.

    1982-01-01

    The view currently held in the Sandia National Laboratory is that, in the case of a meltdown in the reactor core, the probability of a steam explosion is greater than was estimated in WASH-1400, but that the extent and effect of an explosion will be very much smaller than assumed in WASH-1400. This results in a far smaller total risk with regard to containment. In WASH-1400, a nominal conditional probability of 1% was assumed for a containment rupture in a PWR-type reactor, should a large part of the reactor fuel be subject to meltdown during the course of the accident. The German risk analysis study 'Deutsche Risikostudie Kernkraftwerke' dated 1979 considers an explosion of a size sufficient to represent a threat to containment to be considerably more improbable than was assumed in WASH-1400.

  14. Establishing a PWR burn-up library

    1981-01-01

    Starting out from data file ENDF/B IV /1/, a cross-section library has been established for the calculation of operating conditions in pressurized water reactors of the type used in BIBLIS B. The library includes macroscopic, homogenized 2-group cross-sections for all types of fuel elements used in this reactor, including those equipped with boron glass rods. For their calculation the previous irradiation of the fuel has been taken into consideration by approximation. Information on fuel consumption from cell burn-up calculations has been stored in a separate data file. It was designed as a base for the determination of cross sections to be used in the calculation of the incident ''main-steam pipe fracture''. For this library the description of cross sections as a function of the moderator status chose the water densities at 300 0 C/155 bar, 190 0 C/140 bar and 100 0 C/100 bar as fixed values. The burn-up library has been tested by a three-dimensional calculation for the 1sup(st) cycle of the BIBLIS B-reactor using program QUABOX /2/. This showed variances with the anticipated course concerning critically, which can be explained almost quantitatively by known deficiencies of the ENDF/b-IV library. (orig.) [de

    1981-09-01

    The aim of this research effort was to contribute to the development of methods to quantify the risk involved with nuclear power plants. Using a large component, i.e. the containment of the reference plant BIBLIS B (PWR) as sample structure a reliability analysis was performed which is based on realistic assumptions of loads and material properties. For this purpose in many fields it was necessary to develop new methods, collect data, and where not available, obtain data in tests. This effort concentrated on partial aspects and on the other hand on the development of a methodology for an overall reliability concept. According to the results of the previous project, the keypoints of this effort are the treatment of loss of coolant accidents (small leak), earthquake loading, the possibly resulting crackpropagation in the steel hull, and the structural mechanics and material strength aspects of the reinforced concrete hull subjected to impact loading (aircraft impact).

  16. On the failure probability of the primary piping of the PWR

    Schueller, G.I.; Hampl, N.C.

    1984-01-01

    A methodology for quantification of the structural reliability of the primary piping (PP) of a PWR under operational and accidental conditions is developed. Biblis B is utilized as reference plant. The PP structure is modeled utilizing finite element procedures. Based on the properties of the operational and internal accidental conditions, a static analysis suffices. However, a dynamic analysis considering non-linear effects of the soil-structure-interaction is to be used to determine load effects due to earthquake induced loading. Considering realistically the presence of initial cracks in welds and considering annual frequencies of occurrence of the various loading conditions, a crack propagation calculation utilizing the Forman model is carried out. Simultaneously leak and break probabilities using the 'Two Criteria'-Aproach are computed. A Monte Carlo simulation procedure is used as method of solution. (Author) [pt

    In lysimetric field experiments with 2 soil types most common in the Federal Republic of Germany the effects of a continuous contamination as well as of a temporary contamination of the soil caused by a possible accident were simulated to allow forecastings on the resorption of radionuclides by farm plants. Parallel pot experiments (8 kg of soil) in greenhouses and in the field and small pot experiments under reproducible climatic chamber conditions were to examine wether or not transfer data from laboratory and pot experiments can be applied to field conditions. In addition to this, soil types representative according to soil mapping were taken from the locations of the nuclear power plants Biblis and Stade, and their properties were determined. In large-scale comparative pot experiments the relative transfer factors were determined. (orig./DG) [de

    Three-dimensional calculations of the longtime behaviour of PWR can be done in short computing times with satisfactory accuracy for power and burn-up distributions. This has been proved by comparison with operational data of Biblis-B. Various possibilities are investigated to increase the discharge burn-up and to improve the utilization of uranium. In view of the increase of discharge burn-up due to enhanced cycle number (decreased batch size) and decreased neutron leakage these new strategies are intensively studied in the conventional fuel management scheme (Out-in) and in the low leakage fuel management scheme (In-Out). By a conventional fuel management scheme with four cycle operation and a low leakage fuel management scheme with three cycle operation an attractive increase of discharge burn-up to about 40% can be achieved by an increase in the reload enrichment to 4%.

    Requirements and suggestions have been made by authorities and various organisations in a number of countries which define necessary experience and training for the various groups of nuclear power plant personnel. For two countries, the USA and the FRG, a comparison has been made which shows that there is only a slight deviation, taking into account the different education systems. With the example of the Biblis nuclear power plant the training on the job is described. Especially the production or operation department is looked at in more detail. The training is split up into several parts: a general part, such as nuclear physics, reactor physics and engineering, reactor safety, radiation protection and so on and a plant related part, such as arrangement and mode of operation of the plant under normal and accident conditions, license conditions and so on.

    Full Text Available This article examines the possible role of a Christian deonto- logical ethics in the contemporary human rights debate. It concludes that a Christian deontological ethics in the Reformed tradition can be positively engaged in the human rights debate when Biblical theological topics are transposed into moral directives applicable to the current human rights concerns, such as religious extremism, femicide, ideologies of intolerance and ecocide. As an example of the applicability of a Christian deon- tological ethics from a reformed perspective, the following Bibli- cal topics are investigated: human dignity on the basis of the “imago dei”, creation and creational integrity, the kingdom of God and forgiveness. Furthermore, the article proposes that other concepts can be added to this list such as the Biblical idea of life, eschatology, covenant and holiness.

    In a jointly adopted communique in August 1992 the regulations governing the partnerships were laid down. The following principles are given priority: bilateral exchange of operating experience on the basis of equal partnership; the knowledge gained from the exchange of experience is used to improve the operation and safety of the respective partner plant; the partnership programme is free from commercial interests and does not include transfer of funds. Since the establishment of the first partnership relations (Biblis) with an east european nuclear power plant (Balakowo) late in April 1990, a total of 126 reciprocal visits was paid, 82 of which to German nuclear power plants. The balance of the efforts made by German nuclear power plant operators to integrate east european nuclear plant operators can be considered positive. (orig./HP) [de

  7. The finite element response matrix method

    International Nuclear Information System (INIS)

    Nakata, H.; Martin, W.R.

    1983-02-01

    A new technique is developed with an alternative formulation of the response matrix method implemented with the finite element scheme. Two types of response matrices are generated from the Galerkin solution to the weak form of the diffusion equation subject to an arbitrary current and source. The piecewise polynomials are defined in two levels, the first for the local (assembly) calculations and the second for the global (core) response matrix calculations. This finite element response matrix technique was tested in two 2-dimensional test problems, 2D-IAEA benchmark problem and Biblis benchmark problem, with satisfatory results. The computational time, whereas the current code is not extensively optimized, is of the same order of the well estabilished coarse mesh codes. Furthermore, the application of the finite element technique in an alternative formulation of response matrix method permits the method to easily incorporate additional capabilities such as treatment of spatially dependent cross-sections, arbitrary geometrical configurations, and high heterogeneous assemblies.

    Fischer, U.; Wiese, H.W.

    1983-01-01

    For safe handling, processing and storage of spent nuclear fuel a reliable, experimentally validated method is needed to determine fuel and waste characteristics: composition, radioactivity, heat and radiation. For PWR's, a cell-burnup procedure has been developed which is able to calculate the inventory in consistency with cell geometry, initial enrichment, and reactor control. Routine calculations can be performed with KORIGEN using consistent cross-section sets - burnup-dependent and based on the latest Karlsruhe evaluations for actinides - which were calculated previously with the cell-burnup procedure. Extensive comparisons between calculations and experiments validate the presented procedure. For the use of the KORIGEN code the input description and sample problems are added. Improvements in the calculational method and in data are described, results from KORIGEN, ORIGEN and ORIGEN2 calculations are compared. Fuel and waste inventories are given for BIBLIS-type fuel of different burnup. (orig.) [de

  9. PRA for emergency planning: assessing the risk profile of a 3-loop PWR on the basis of US and German risk studies

    Chakraborty, S.; Fuchs, H.; Gubler, R.; Landolt, J.; Miteff, L.

    1985-01-01

    Emergency planning around nuclear power plants should be based on a realistic assessment of their risk profile. Since the results of the Rasmussen study (WASH-1400) and later of the German risk study (Phase A) were not judged to be fully representative for NPP's in Switzerland, an investigation was started to transfer applicable US and German results to a Swiss 3-loop PWR (Goesgen) and to assess the impact of differences in plant design compared to Surry-1 and Biblis-B. The core melt probability for Goesgen was calculated to be more than a factor of ten smaller than for the US and German studies. This is mainly due to more redundancy/better separation (especially in the emergency feedwater) and to partial automation of cooldown after a small break. The results were instrumental in limiting the release categories to be used as reference cases for emergency planning. Further reduction of postulated accidental releases is expected from the current source term research

    The excess reactivity of a pressurized water reactor is compensated by boron, disolved in the moderator. In addition during the first cycle boron poison rods are placed in fuel assemblies without control rods. The burn-up behavior of a poison rod in a Biblis B fuel assembly is analysed in the present paper. Multigroup spectrum calculations were performed. The influence of critical boron concentration depending from burn-up, the changes of fuel concentration and the concentration of burnable poison were taken into consideration. Furthermore the built-up of rapidly saturating fisson products 135 Xe and 149 Sm was considered. The interaction of these effects are discussed. Spatial influences are emphasized most. Finally two group cross sections were calculated. The results are compared with calculations for a fuel assembly of the same type without burnable poison rods. (orig.) [de

    After instances of maloperation, the causes of defects, the effectiveness of the measures taken to control the situation, and possibilities to avoid future recurrences need to be investigated above all before the plant is restarted. The most important aspect in all these efforts is to check the sequence in time, and the completeness, of the control measures initiated automatically. For this verification, a computer system is used instead of time-consuming manual analytical techniques, which produces the necessary information almost in real time. The results are available within minutes after completion of the measures initiated automatically. As all short-term safety functions are initiated by automatic systems, their consistent and comprehensive verification results in a clearly higher level of safety. The report covers the development of the computer system, and its implementation, in the Gundremmingen nuclear power station. Similar plans are being pursued in Biblis and Muelheim-Kaerlich. (orig.)

For instance, mechanical and thermal stress, radiation exposure, denting or wastage can considerably affect the aging of plant components and thus cause premature failures of components. In this presentation, the term 'Plant Aging' in nuclear power plants is to be understood more comprehensively than wear on components and material fatigue. In addition, nuclear power plants are to be adjusted to the advancing state of the science and technology (state-of-the-art) in order to guarantee safe operation at all times. The preventive maintenance - as a countermeasure to plant aging - comprises the systematic checks and servicing of the plant systems in operation and follows aging by inspection and tests. Experience with Rheinisch-Westfaelisches Elektrizitaetswerk AG (RWE) preventive maintenance program at the Biblis NNP (1300 MW, PWR) is discussed. The concept of an 'Integrated Maintenance System' as a means to avoid 'Plant Aging' is presented

    A compact detection system was built for multi-angle inspection of pipes, consisting of a high-sensitivity radiometric line scanner and an ultrasonic manipulator. Improved flaw imaging quality is achieved with this system as compared to film radiography. Measurements have been carried out on site in a nuclear power plant and in a laboratory. Better flaw imaging quality was also achieved in the testing of water-filled pipes. Non-linear tomosynthesis was applied for processing and interpretation of measured data. The system delivers considerably better images of planary materials inhomogeneitites, (such as cracks and lack-of-bond defects).

Bei der Inspektion von Rundschweissnaehten an Rohren mit ca. 8... 20 mm Wanddicke wurde eine Verbesserung der Bildqualitaet im Vergleich zur Filmradiographie erreicht. Diese Messungen wurden in einem Kernkraftwerk unter Vor-Ort-Bedingungen sowie im Labor ausgefuehrt. Ein signifikantes Ansteigen der Bildqualitaet wurde auch bei der Pruefung von wassergefuellten Rohren erzielt. Methoden der nicht-linearen Tomosynthese wurden fuer die Verarbeitung und Interpretation der gemessenen Projektionsdaten genutzt. Das entwickelte System gestattet eine erhebliche Verbesserung der Anzeige von planaren Materialinhomogenitaeten (z.B. Risse und Bindefehler). (orig./DGE)

  20. Compact sodium cooled nuclear power plant with fast core (KNK II- Karlsruhe), Safety Report

    International Nuclear Information System (INIS)

    1977-09-01

    After the operation of the KNK plant with a thermal core (KNK I), the installation of a fast core (KNK II) had been realized. The planning of the core and the necessary reconstruction work was done by INTERATOM. Owner and customer was the Nuclear Research Center Karlsruhe (KfK), while the operating company was the Kernkraftwerk-Betriebsgesellschaft mbH (KBG) Karlsruhe. The main goals of the KNK II project and its special experimental test program were to gather experience for the construction, the licensing and operation of future larger plants, to develop and to test fuel and absorber assemblies and to further develop the sodium technology and the associated components. The present safety report consists of three parts. Part 1 contains the description of the nuclear plant. Hereby, the reactor and its components, the handling facilities, the instrumentation with the plant protection, the design of the plant including the reactor core and the nominal operation processes are described. Part 2 contains the safety related investigation and measures. This concerns the reactivity accidents, local cooling perturbations, radiological consequences with the surveillance measures and the justification of the choice of structural materials. Part three finally is the appendix with the figures, showing the different buildings, the reactor and its components, the heat transfer systems and the different auxiliary facilities [de

    The paper explains the systematic approaches and practical aspects of evaluation of NPP operating reports and implementation of identified remedial action for enhancing the safety in terms of human, organisational, and technology factors. The procedures adopted for the Grafenrheinfeld nuclear power station (KKG) serve as an example. (orig./CB) [German] Ein wichtiger Bestandteil zur Erhaltung und Fortentwicklung des Sicherheitsniveaus ist das Lernen aus der Erfahrung. Hierzu wiederum ist ein systematisches Vorgehen zur Vermeidung von Fehlern und Behebung von Schwachstellen menschlicher, technischer und organisatorischer Natur unabdingbare Voraussetzung. Die Anwendung einer umfassenden Auswertemethodik beinhaltet - die Erfassung und Informationsweitergabe externer und interner Vorkommnisse und Erfahrungen - eine systematische Analyse/Auswertung - eine konsequente Umsetzung der Abhilfemassnahmen unter Einbeziehen aller betroffenen Organisationseinheiten. Wie erfolgt die Umsetzung dieser Vorgaben in die Praxis? Im Kernkraftwerk Grafenrheinfeld (KKG) ist die Auswertung von externen und internen Betriebserfahrungen als Aufgabe im Betriebshandbuch (BHB) 'Personelle Betriebsorganisation' vorgegeben und im Detail im Sinne der Ablauforganisation im Qualitaetssicherungshandbuch in Qualitaetssicherungsanweisungen (QSA) beschrieben.

    Measurements of an experiment in a pipe system with pump shutdown and valve closing have been performed in the nuclear power plant KRB II. Comparative calculations of fluid and structure including interaction show an excellent agreement with the measured results. Theory and implementation of the fluid/structure interaction and the results of the comparison are described. It turns out that the consideration of the fluid/structure interaction is mostly a significant increase of the effective structural damping. (orig.) [Deutsch] Es wurden Messungen am nuklearen Nachkuehlsystem des Kernkraftwerks Gundremmingen (KRB II) bei einem Versuche mit Pumpenabschalten und Ventilschliessen durchgefuehrt. Vergleichsrechnungen der Fluid-Strukturdynamik unter echter Beruecksichtigung der Wechselwirkung ergaben eine ausgezeichnete Uebereinstimmung der Rechnung mit den Messungen. Es werden Theorie und Implementierung der Koppelung der Fluid- und Struktur-Berechnungen sowie die Vergleiche von Messung und Rechnung beschrieben. Es ergibt sich, dass die Beruecksichtigung der Wechselwirkung notwendig ist zur genaueren Berechnung von `weichen` Rohrleitungsystemen. Eine wichtige Folge der Wechselwirkung ist meist eine deutliche Erhoehung der effektiven Strukturdaempfung. (orig.)

    On June 29, 2006, the Radiochemical Laboratory of AREVA NP GmbH (formerly Siemens AG) in Erlangen celebrated its fiftieth anniversary. The occasion was marked by an event attended by more than 1,000 guests, among them Werner Gebauhr, the 85-year-old founder and first head of the Laboratory; the Managing Directors of AREVA NP GmbH, Ralf Gueldner and Ruediger Steuerlein; representatives of universities, research institutions, power utilities, and public authorities. The present head of the Radiochemical Laboratory, Wilfred Morell, sketched the highlights of the work performed over the past fifty years, which ranged from solid-state and very-high-purity materials technologies to development and service activities for nuclear technology. Manfred Erve, head of the Technical Center of AREVA NP GmbH, of which the Radiochemical Laboratory is a part, emphasized the changes in priorities over the past fifty years, which had always been met successfully by Radiochemistry. In the scientific part of the event, Wolfgang Schwarz (E.ON Kernkraftwerk GmbH, KKW Isar), Ulf Ilg (EnBW Kraftwerk AG, KKW Philippsburg), and Hans-Josef Allelein (Gesellschaft fuer Anlagen- und Reaktorsicherheit mbH) explained 3 major subject areas in which Erlangen Radio-chemistry over many years has contributed basic findings (see other articles in this atw issue). On the occasion of the anniversary, a comprehensive booklet was published under the title of '50 Jahre Radiochemie Erlangen - 1956-2006'. (orig.)

    The application of high-resolution gamma spectroscopy with whole-body and partial-body counters shows a steadily rising upward trend over the last few years. This induced the ``Arbeitskreis Inkorporationsueberwachung`` of the association ``Fachverband fuer Strahlenschutz e.V.`` to organise a meeting for joint elaboration of a guide on recommended applications of this measuring technique, based on a review of existing experience and results. A key item on the agenda of the meeting was the comparative evaluation of the Ge semiconductor detector and the NaI solid scintillation detector. (orig./CB) [Deutsch] Der Einsatz der hochaufloesenden Gammaspektroskopie in Ganz- und Teilkoerperzaehlern hat in den letzten Jahren stetig zugenommen. Der ``Arbeitskreis Inkorporationsueberwachung`` des Fachverbandes fuer Strahlenschutz e.V. hat darum bisherige Erfahrungen zusammengetragen und Empfehlungen fuer den Einsatz dieser Messtechnik erarbeitet. Der Schwerpunkt der Tagung lag beim Vergleich von Germaniumhalbleiter- mit Natriumjodid-Festszintillationsdetektoren.Tl-Detektoren eignen sich v.a. beim Vorhandensein bekannter und zeitlich konstanter Nuklidvektoren (Kernkraftwerke, Nuklearmedizin). Bei unbekanntem bzw. variablem Nuklidvektor (Stoerfall, Unfall, Forschung) sollen Ge-Detektoren benutzt werden (orig./ABI)

    The Basic Design of the EPR has now been completed. The containment plays a major safety-related role with respect to protection of the environment against radioactive releases. The EPR features a double (steel-reinforced concrete/prestressed concrete) containment design, with the inner containment coated additionally with a fibreglass-reinforced plastic (FRP) liner in certain areas. This means that containment leaktightness is provided mainly by the prestressed concrete and the FRP liner in the event of a postulated accident. The numerous findings of the tests carried out so far in both France and Germany are summarized. (orig.) [German] Das Basic Design fuer den EPR ist fertiggestellt. Entscheidend fuer eine Realisierung wird neben der politischen Akzeptanz vor allem die Wettbewerbsfaehigkeit mit anderen Energietraegern sein. Im EPR-Projekt wird der hohe Sicherheitsstandard der heutigen Kernkraftwerke in Deutschland und Frankreich ergaenzt, indem zusaetzlich technische Massnahmen ergriffen werden, um die Konsequenzen beim unterstellten Versagen aller sicherheitstechnischen Einrichtungen mit der Folge eines postulierten Niederschmelzen des Kerns technisch zu beherrschen.

    The Risk Reduction Category (RRC-A) is considered in the safety demonstration of nuclear reactors in addition to design basis operating conditions (Plant Condition Category, PCC), in order to analyze with a risk reduction approach any operating conditions with multiple failures. As extending the operating conditions of the plant 'beyond design basis', the Risk Reduction Category (RRC-A) is also denoted as Design Extension Condition (DEC-A). In the German licensing framework, the RRCA (or DEC-A) transients correspond to safety assessment level '4b' of the 'Sicherheitsanforderungen an Kernkraftwerke' (Safety Requirements for Nuclear Power Plants), Az. RS I 5 - 13303/01 of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. These RRC-A (or DEC-A) operating conditions require specific design provisions (implemented by manual or automatic action), known as RRC-A measures, intended to render consequences of accumulated failures admissible. In contrast, RRC-B constitute severe accidents that lead to core melt. Identification of RRC-A operating conditions and corresponding RRC-A measures is based on the use of results of probabilistic safety assessments. After the Fukushima accident the RRC-A accidents like Station Black Out (SBO) or Loss of Ultimate Heat Sink (LUHS) are of particular interest in the safety assessment of nuclear new builds. In several chapters of the Safety Analysis Report it is demonstrated that the AREVA EPRTM design is resistant at RRC-A accident conditions. (orig.)

    Seven advanced nuclear power plants in Germany can withstand a frontal crash by a full-tanked Jumbo-Jet. But for five older plants even smaller planes can cause an hazard impossible to control. A fog generation around the power plants, favorized by operators and politicians, to camouflage this plants against terroristic flights is absurd because of the possibility of flight automation. However terrorists may attack reactors also from the ground, but how they can do is top secret. (GL) [German] Einem frontalen Aufprall eines voll getankten Jumbo-Jets mit hoher Geschwindigkeit koennen in Deutschland sieben moderne Kernkraftwerke standhalten. Bei fuenf aelteren Modellen kann dagegen selbst ein kleineres Flugzeug ein schwer beherrschbares Unglueck ausloesen. Obwohl Experten eine vorzeitige Schliessung solch alter Meiler fuer realistisch halten, ist die Verhandlungslage aufgrund ideologischer Einfluesse verfahren. Die von Betreibern und Politikern gern gepriesenen Nebelwerfer zur Tarnung der Kraftwerke sind wegen der Moeglichkeit des Instrumentenfluges sinnlos. Die beste Abwehr bieten vorgelagerte Schutzbauten aus Beton. Jedoch koennen Terroristen Reaktoren auch vom Boden aus gefaehrden, wie, ist natuerlich geheim.

    With its decision on December 20{sup th}, the Federal Administrative Court (BVwerfG) came to the legally valid conclusion that after the Fukushima nuclear power plant accident, the supervision court order related to the law on nuclear installation by the Hessian Ministry for the Environment, in order to stop operating nuclear power plants Biblis A and B for 3 months or rather not to put in operation again, was unlawful (BVwerfG 7 B 18.13 und 7 B 19.13). Beforehand, the Hessian Administrative Court (Hess. VGH) had already pronounced its judgement on February 27{sup th} 2013. The supervising orders were part of the so-called nuclear power moratorium. They were issued after the resolution of the federal government, at demand of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) towards their nearby countries, and were identically executed by the supervisory authority of the other site-countries. Besides Biblis in Hesse, nuclear power plants in Neckarwestheim I and Philippsburg 1, Baden-Wurttemberg, Isar 1 in Bavaria, Unterweser in Lower Saxony, as well as Brunsbuettel in Schleswig-Holstein, were affected. However only RWE took legal action and was now affirmed - after the Hessian VGH verdict- by the highest German administrative court: The nuclear power moratorium - the first step to withdrawal of nuclear power in Germany - was unlawful. The decision taken by the BVerwG - as well as the one by the Hessian VGH - indicates a juridical clear and precise argumentation. The partially polemic and unobjective critic, which the VHG-verdict experienced, did not disguise, just as little as the political conflict concerning the withdrawal from nuclear energy, the view of federal judges, regarding the decision-relevant questions nor did they influence their reply. The political primacy finds its limits in the bounds of justice. Existing rights do not become thus a paper waste because there is a fundamental decision. This takes effectiveness for

    Plant operations management systems, being IT application systems, provide integral support of the business processes making up plant operations management. The use of plant operations management systems improves mutually interdependent factors, such as high economic performance, high availability, and maximum safety. Since its commissioning in 1988, the Emsland nuclear power station (KKE) has been run with the IBFS plant operations management system. The work flow management system (WfMS), a module of IBFS, is described as an example of job order processing. IBFS-WfMS is to optimize all processes, thus cutting costs and ensuring that processes are run and documented reliably. Assessing the savings effect achieved through the use of IBFS-WfMS clearly reveals the savings in work/time achieved by the system. These savings are quoted as approx. 4 minutes and DM 10, respectively, per working step, which corresponds to several dozens of manyears or several million DM per annum in the KKE plant under consideration. This result can be extrapolated to other plants. (orig.) [German] Betriebsfuehrungssysteme stuetzen als EDV-Anwendungssystem integral die Geschaeftsprozesse der Kraftwerksbetriebsfuehrung.

    The Y2K problem has many facets due mainly to two reasons: The extremely wide use of microcomputers, and the complexity of automation in modern industrial plants. For the past two years, Siemens AG has been checking the Y2K conformity of its products. The result of these investigations is this: All automation equipment, almost without exception, is in conformity with the year 2000 requirements as it works without the date function causing the errors. A few occasional malfunctions were discovered in older computer-supported operating and monitoring stations and in process computer applications. However, malfunctions are not going to cause failures of the system but only make its use more difficult. (orig.) [German] Ursache des Jahr-2000-Problems ist die Unfaehigkeit gewisser aelterer Software, das Jahresdatum 2000 beim Uebergang der letzten beiden Ziffern von '99' auf '00' richtig zu verarbeiten. Potenziell betroffen sind alle Geraete und Systeme, die in irgendeiner Form Rechner oder Mikrorechner enthalten. Das Jahr-2000-Problem ist sehr vielschichtig. Dies resultiert im Wesentlichen aus zwei Gruenden: Der extrem weiten Verbreitung von Mikrorechnern und der Komplexitaet der Automatisierung moderner Industrieanlagen. Die Siemens AG ueberprueft seit zwei Jahren die 2000-Jahr-Konformitaet ihrer Produkte. Ergebnis der Untersuchungen ist: Automatisierungsgeraete sind fast ausnahmslos Jahr-2000 konform, da sie ohne die fehlerverursachenden Datumsfunktionen auskommen. Vereinzelte Fehlfunktionen wurden in aelteren rechnergestuetzten Bedien- und Beobachtungssystemen sowie in Prozessrechneranwendungen gefunden. Fehlfunktionen fuehren jedoch meist nicht zum Versagen des Systems, sondern erschweren nur dessen Nutzung. In den sicherheitsrelevanten Bereichen der Kernkraftwerke werden ausschliesslich die vom Jahr-2000-Problem nicht betroffenen Automatisierungsgeraete eingesetzt. (orig.)

  16. Strategy for decommissioning of NPP's in Germany

    According to German Atomic Law, two different strategies are possible, i.e. direct dismantling and safe enclosure before dismantling. Both approaches have their advantages and disadvantages. Taking into account the site and plant specific conditions the optimal strategy can be evaluated. Both approaches have been applied in Germany in the past. The German Atomic Law and the Radiation Protection Ordinance (June 2002) were adapted recently (July 2002). Additionally, the life operation time of the German NPP's was fixed in a new law (April 2002): Orderly Termination of the Commercial Production of Nuclear Electricity. These issues have made it necessary for the power utilities to review the strategies applied. As long as the final disposal in Germany is still an open issue, the construction of local Interim Stores is necessary to be able to dismantle a NPP. The basic strategies are not excluding each other and it seems clear today, that the optimal approach is a combination of these strategies, e.g. dismantling of all auxiliary systems and leaving activated parts for a longer SE period. Within this approach the advantages of both basic strategies have been integrated in one. The EWN GmbH has developed such integrated but still different approaches for the decommissioning projects of the Kernkraftwerke Greifswald (KGR) and the Arbeitsgemeinschaft Versuchsreaktor (AVR) Juelich. It can be stated that the decommissioning of a NPP does not present technical issues of concern, but is more a project management issue, although surrounded by sometime intricate political and juridical boundary conditions. A major strategy change is to be expected only when final disposal capacities are available in the future. (authors)

    Nuclear power plants are complex and technically elaborate systems whose aim is to produce electricity. They must meet the highest safety requirements. Within the reactors, nuclear reactions and radioactive transformations release energy which is used to evaporate water. The steam generated drives turbines that in turn are coupled with generators which convert the kinetic energy provided by the turbines into electrical energy. The process is easy to illustrate but difficult to control and requires technical equipment such as kilometre-long pipe systems. Austenitic steel is frequently used for this purpose because of its high strength and corrosion resistance. The individual pipe components are joined by welding. However, welds may contain hidden defects. Cracks, lack of fusion or pore nests that can remain undetected may have catastrophic consequences. Therefore, all welds in a nuclear power plant, without exception, must be checked. Approved non-destructive methods use ultrasound and X-ray. The technology developed at BAM is called TomoWELD.

Der Dampf treibt Turbinen an und die wiederum sind mit Generatoren gekoppelt, welche die durch die Turbinen bereitgestellte kinetische Energie in elektrische Energie umwandeln.

    2000-01-01

    Kernkraftwerk Brunsbuettel (KKB) is a KWU 806 MW e BWR located at the lower river Elbe, in Germany. The reactor has been in operation since 1976 and is now operating in its 14. cycle. The core supervision at KKB is performed with the ABB CORE MASTER system. This system mainly contains the 3-D simulator PRESTO supplied by Studsvik Scandpower A/S. The core supervision is performed by periodic PRESTO 3-D evaluations of the reactor operation state. The power distribution calculated by PRESTO is adapted with the ABB UPDAT program using the on-line LPRM readings. The thermal margins are based on this adapted power distribution. Related to core supervision, the function of the PRESTO/UPDAT codes is presented. The UPDAT method is working well and is capable of reproducing the true core power distribution. The quality of the 3-D calculation is, however, an important ingredient of the quality of the adapted power distribution. The adaptation method as such is also important for this quality. The data quality of this system during steady state and off-rate states (reactor manoeuvres) are discussed by presenting comparisons between PRESTO and UPDAT thermal margin utilisation from Cycle 13. Recently analysed asymmetries in the UPDAT evaluated MCPR values are also presented and discussed. Improvements in the core supervision such as the introduction of advanced modern nodal methods (PRESTO-2) are presented and an alternative core supervision philosophy is discussed. An ongoing project with the goal to update the data and result presentation interface (GUI) is also presented. (authors)

  19. The term 'danger' according to the act on protection against nuisances - assessment of incidents on account of external effects

    International Nuclear Information System (INIS)

    Rehbinder, E.

    1976-01-01

    The author deliberates critically on the opinion taken up in the judgments of the Higher Administrative Court at Lueneburg dated February 25th, 1975 and June 27th, 1975 in the case of Dow Chemical, according to which the facilities subject to a licence under the Federal act on protection against nuisances have to be erected in such a way that dangers for the general public and the neighbourhood (in this case danger through gas cloud explosions from a chlorine plant of the Kernkraftwerk Stade) are excluded. If this view, hitherto only expressed by the OVG Lueneburg in summary proceedings according to section 80 paragraph 5 VwGO, gains acceptance, then, in the opinion of the author, the open air construction of the big chemical industry's plants would be illegal to a large extent. While defining the term of danger in police law, Rehbinder applies the term of probability and proportionateness to the term of danger in section 3 BImSchG. On the other hand, the term of danger would have to be taken in a wider sense in section 1 No. 2 and section 7 sub-section No. 2 and 4 Atomic Energy Act, because of the danger potential being here bigger in the long run. In a final conclusion with a view to politics and law, the author states, amongst other things, the following: an exaggerated safety philosophy hides the danger of a political discrediting of the whole environment protection idea, a danger which ought to weigh in the end more heavily than the minute remaining risk for the life and the health of people if a facility which has to have a licence is not protected against absolutely unlikely external incidents.

    Skupinski, E.

    1993-01-01

    Initiated by the Commission of the European Communities (CEC), this seminar was jointly organized by Kernkraftwerke RWE Bayernwerk GmbH (KRB) and the CEC at Gundremmingen-Guenzburg (D), where the former KRB-A BWR is presently being dismantled. The meeting aimed at gathering a limited number of European experts for the presentation and discussion of operations, the results and conclusions on techniques and procedures presently applied in the dismantling of large-scale nuclear installations in the European Community. Besides the four pilot dismantling projects of the presently running third R and D programme (1989-93) of the European Community on decommissioning of nuclear installations (WAGR, BR-3 PWR, KRB-A BWR and AT-1 FBR fuel reprocessing), the organizers selected the presentation of topics on the following facilities which have a significant scale and/or representative features and are presently being dismantled: the Magnox reprocessing pilot plant at Sellafield, the HWGCR EL4 at Monts d'Arree, the operation of an on-site melting furnace for G2/G3 GCR dismantling waste at Marcoule, an EdF confinement conception of shut-down LWRs for deferred dismantling, and the technical aspects of the Greifswald WWER type NPPs decommissioning. This was completed by a presentation on the decommissioning of material testing reactors in the United Kingdom and by an overview on the conception and implementation of two EC databases on tools, costs and job doses. The seminar concluded with a guided visit of the KRB-A dismantling site. This meeting was attended by managers concerned by the decommissioning of nuclear installations within the European Community, either by practical dismantling work or by decision-making functions. Thereby, the organizers expect to have contributed to the achievement of decommissioning tasks under optimal conditions - with respect to safety and economics - by making available a complete and updated insight into on-going dismantling projects and by

  2. Experimental investigations of pressure and temperature loads on a containment after a loss-of-coolant accident

    Kanzleiter, T.F.

    1976-01-01

    For the design of an LWR containment one of the important conditions to be considered is the rapid rise of internal pressure and temperature caused by a loss-of-coolant accident (LOCA) of the primary cooling system. The phenomena occurring within a containment during a LOCA are currently investigated through experiments with a model containment. The experimental results are compared with the results of model calculations to improve the calculational methods. An experimental facility was built, consisting of a primary coolant circuit and a special model containment. The model containment, built in conventional reinforced concrete, has a diameter of 12 m, a height of 12.5 m, a capacity of 580 m 3 and is designed for an internal pressure of 6 bar. The interior is divided by concrete walls and removable partitions into several compartments, which are interconnected through openings with adjustable cross sections. By exchanging the removable partitions it is possible to modify the interior of the containment and to simulate different containment shapes. For the first experiments a PWR configuration with nine compartments has been installed. The model scales of the compartment volumes and the overflow areas are about 1 : 64 compared to the 1200 MW PWR plant Biblis A. (Auth.)

    Under the official inquiry ''Future Nuclear Energy Policies'', KfK have carried out a number of studies concerning the hazards arising from core-destructive accidents at the SNR-300 reactor. Among these, there was the so-called ''Upper Limit Study'' providing a critical evaluation of literature on all research done on core-destructive accidents (Bethe-Tait excursion) with a high mechanic energy release potential; the other one was the so-called ''SAI Study'' (a cooperation of KfK, Science Applications, Inc. (SAI) and Interatom (IA)) which investigated the hazards of an uncontrolled coolant flow rate disturbance occurring in the SNR-300 reactor. KfK also took part in the analysis of hazards comparing the SNR-300 reactor with an LWR-type reactor like the one at Biblis B, ordered by the Federal Ministry of Research and Technology (BMFT). These studies have already been dealt with KfK-Nachrichten, 14th annual set issue 4/1982. The article on hand summarizes and evaluates once more the most important results. (orig./RW) [de

  4. Docommissioning of nuclear power plants

    Essmann, J.

    1981-01-01

    The German utilities operating nuclear power plants have long concerned themselves with aspects of decommissioning and for this purpose an engineering company was given a contract to study the entire spectrum of decommissioning. The results of this study have been available in autumn 1980 and it is possible to discuss all the aspects of decommissioning on a new basis. Following these results no change in the design concept of LWR nuclear power plants in operation or under construction is necessary because the techniques, necessary for decommissioning, are fully available today. The technical feasibility of decommissioning for power plants of Biblis A and KRB type has been shown in detail. The calculations of the quantity of waste produced during removal of a nuclear power plant could be confirmed and it could be determined with high procedure. The radiation dose to the decommissioning personnel is in the range of the radiation protection regulations and is in the same range as the radiation dose to the personnel within a yearly inservice inspection.

    1993-01-01

    This study presents decommissioning costs of NPP's in Germany. In 1977, a similar study had been carried out by NIS Ingenieurgesellschaft for the Commission of the European Communities. The experience gained during the last 15 years from the decommissioning of nuclear installations, as well as the developments made in calculating costs were the reasons to update the 1977 study. The cost estimates were carried out for the German LWRs, Biblis A (PWR) and Brunsbuettel (BWR) taken as reference plants. For the calculations, the software programme STILLKO 2 (owned by the German VDEW) was used. Not only have cost calculations been carried out, but also data have been obtained relating to manpower, occupational radiation exposure, masses of material to be dismantled and radioactive waste generated. The results enable a direct comparison with those of the 1977 study and show the most important differences. In a separate chapter, costs for single items are presented so that comparison with decommissioning costs from other EC countries may be possible.

    Wiehr, K.

    1988-05-01

    This report is a summary of experimental investigations describing the fuel rod behavior in the refilling and reflooding phase of a loss-of-coolant accident of a PWR. The experiments were performed with 5x5 and 7x7 rod bundles, using indirectly electrically heated fuel rod simulators of full length with original PWR-KWU-geometry, original grid spacers and Zircaloy-4-claddings (Type Biblis B). The fuel rod simulators showed a cosine shaped axial power profile in 7 steps and continuous, respectively. The results describe the influence of the different parameters such as bundle size on the maximum coolant channel blockage, that of the cooling on the size of the circumferential strain of the cladding (azimuthal temperature distribution) a cold control rod guide thimble and the flow direction (axial temperature distribution) on the resulting coolant channel blockage. The rewetting behavior of different fuel rod simulators including ballooned and burst Zircaloy claddings is discussed as well as the influence of thermocouples on the cladding temperature history and the rewetting behavior. All results prove the coolability of a PWR in the case of a LOCA. Therefore, it can be concluded that the ECC-criteria established by licensing authorities can be fulfilled. (orig./HP) [de

    2015-01-01

    A coupled neutronics thermal-hydraulics code NODAL3 has been developed based on the nodal few-group neutron diffusion theory in 3-dimensional Cartesian geometry for a typical pressurized water reactor (PWR) static and transient analyses, especially for reactivity initiated accidents (RIA). The spatial variables are treated by using a polynomial nodal method (PNM) while for the neutron dynamic solver the adiabatic and improved quasi-static methods are adopted. A simple single channel thermal-hydraulics module and its steam table is implemented into the code. Verification works on static and transient benchmarks are being conducting to assess the accuracy of the code. For the static benchmark verification, the IAEA-2D, IAEA-3D, BIBLIS and KOEBERG light water reactor (LWR) benchmark problems were selected, while for the transient benchmark verification, the OECD NEACRP 3-D LWR Core Transient Benchmark and NEA-NSC 3-D/1-D PWR Core Transient Benchmark (Uncontrolled Withdrawal of Control Rods at Zero Power). Excellent agreement of the NODAL3 results with the reference solutions and other validated nodal codes was confirmed. (author)

  9. Integrated disturbance analysis (IDA): A basis for expert systems in nuclear power plants

    1987-01-01

    In the framework of a project sponsored by the Bundesminister fur Forschung und Technologie (BMFT) and the Rheinisch-Westfalisches Elektrizitatswerk AG (RWE) the concept of Integrated Disturbance Analysis (IDA) has been developed and applied to the Biblis Unit B Nuclear Power Plant. Rather than using the classical approach, which aims at finding the cause of a plant disturbance, the main goal was to make transparent to the operator what it really means for the process, when a set of parameters begins to deviate from its normal state. Therefore the goal was to help the operator to combine the information on the individual process parameters to the complete picture of the evolving transient, thus facilitating the decision about the importance of a disturbance for operational safety. Considering this goal the most important subjects taken care of were: to extend event sequence analysis by means of analog information; to provide adequate modelling of time dependent processes and feedback loops; to integrate IDA information effectively into the existing control room environment

  10. The finite element response Matrix method

    International Nuclear Information System (INIS)

    Nakata, H.; Martin, W.R.

    1983-01-01

    A new method for global reactor core calculations is described. This method is based on a unique formulation of the response matrix method, implemented with a higher order finite element method. The unique aspects of this approach are twofold. First, there are two levels to the overall calculational scheme: the local or assembly level and the global or core level. Second, the response matrix scheme, which is formulated at both levels, consists of two separate response matrices rather than one response matrix as is generally the case. These separate response matrices are seen to be quite beneficial for the criticality eigenvalue calculation, because they are independent of k /SUB eff/. The response matrices are generated from a Galerkin finite element solution to the weak form of the diffusion equation, subject to an arbitrary incoming current and an arbitrary distributed source. Calculational results are reported for two test problems, the two-dimensional International Atomic Energy Agency benchmark problem and a two-dimensional pressurized water reactor test problem (Biblis reactor), and they compare well with standard coarse mesh methods with respect to accuracy and efficiency. Moreover, the accuracy (and capability) is comparable to fine mesh for a fraction of the computational cost. Extension of the method to treat heterogeneous assemblies and spatial depletion effects is discussed

    Full Text Available The objective of this study was to analyze lepidopterous insects with diurnal habits (butterflies associated with a native forest portion. Eight traps with bananas installed at 1.0, 2.0, 3.0 and 4.0 m above soil surface were used. Samplings were obtained on a weekly basis from December 2005 to December 2006 in the county of São Sepé, RS. The faunistic indices represented by frequency, constancy, abundance and dominance were analyzed. Height of flight and species diversity were also evaluated. A total of 737 individuals of the Nymphalidae family were collected, which were classified into six subfamilies, 16 genus and 21 species. The most representative species were: Euptychia sp., Hamadryas feronia, Taygetis ypthima, Epiphile huebneri, Biblis hyperia, Taygetis sp.1 and Praepedaliodes phanias. The diversity indices of Shannon and Margalef indicate greater diversity at the height of 4.0 m and lower diversity at the height of 1.0 m, showing relative abundance as an important parameter in determining diversity. About 70% of the collected species were characterized as frequent, common, non-dominant and of accidental occurrence. Hamadryas feronia and Euptychia sp. were constant, dominant and very frequent. The species Euptychia sp. and Taygetis ypthima had height of flight close to the soil surface.

    1982-01-01

    The Fact Finding Committee on 'Future Nuclear Power Policy' established by the 8th German Federal Parliament in its report of June 1980 among other items published the recommendation to commission a 'risk oriented analysis' of the SNR-300 in order to enable a pragmatic comparison to be made of the safety of the German prototype fast breeder reactor and a modern light water reactor (a Biblis B PWR). The Federal Minister for Research and Technology in August 1981 officially commissioned the Gesellschaft fuer Reaktorsicherheit (GRS) to conduct the study. Following a recommendation by the Fact Finding Committee, additional studies were performed also by a group of opponents of the breeder reactor. On the instigation of the group of opponents the delivery date of the study was altered several times and finally set at April 30, 1982. GRS submitted its report by this deadline. However, a joint report by the two groups could not be compiled, as had been requested by the client, because the contributions of the opponents were not made available until mid-May 1982 and then only as an 'interim report'. In summary, the GRS study indicates that the frequency and severity of major accidents is lower for the SNR-300 at the Kalkar site than for a PWR as covered in the German Nuclear Power Plant Risk Study.

    Work on the German Risk Study is under contract of the Federal Ministry of Research and Technology. The reference plant for the analysis is the Biblis nuclear power plant, Unit B, a KWU pressurized water reactor of the 1300 MWel class. The plant is in operation since 1976. First results on Phase A of the study have been published in 1979. Investigations on Phase B have been foreseen to endeepen the analysis. The principal purpose of these investigations is to improve and to optimize the plant's safety features on a more realistic basis. Main objectives of Phase B are: - Completeness of accident event tree analysis taking into account further accident initiating events. - Identification and analyses of accident management measures which are adequate to minimize accidental risk. - improvement of the analysis on an as far as possible realistic basis, thereby taking into account recent results of safety research. The paper deals with the most important results of the plant analyses (level 1 and level 2) which have been performed within the scope of Phases B of the study

    The most important results of the German risk study of a nuclear power plant equipped with a pressurized water reactor were published in August 1979. The main volume of the study with the approach used and the results elaborated has been available for reference since late 1979. Eight technical volumes contain detailed descriptions and documentations of the investigations carried out. The reference facility used as a basis for the technical plant studies was unit B of the Biblis Nuclear Power Station, a KWU PWR of 3750 MW thermal power. This contribution provides more detailed explanations of the methods and the results of the risk study illustrated by examples. The description refers to accident categories and categories of radioactivity releases, probabilities of specific sequences of accident events, and the damage associated with core meltdown accidents as a function of various types of failure. For purposes of evaluation and application of the results the limits in the basic assumptions of the study are referred to. (orig./HP) [de

    In 1990, I visited four utility companies that own and operate pressurized water reactor (PWR) plants in different countries. The purpose of my visits and associated research was to compare nuclear power plant operator and technician training programs. The companies were: Duke Power Company (DUKE) in the United States, Electricite de France (EDF) in France, Kansai Electric Power Company (KEPCO) in Japan, and RWE Energie AG (RWE) in Germany. The purpose of this paper is to highlight selected aspects of the comparison. First, comparisons of the four subject utilities and four typical nuclear power stations operated by each company, McGuire, Paluel, Ohi, and Biblis, are provided. Then comparisons of new employee demographics and training program specific content are provided. Finally, some general observations are drawn from the comparisons. The comparisons are based on information obtained from documents, interviews, and visits to stations and training centers. However, some interpretation of the information was necessary in order to enable a comparison. For example, categorization of training modules requires judgement, interpretation, and translation. In all cases, the information is intended to be representative or typical, rather than statistically precise

  17. Trajectories in a marked temperature inversion in mountainous country

    Koppert, H.J.; Wippermann, F.

    1980-01-01

    This study investigates the flow conditions occurring in marked temperature inversions in mountainous country, which frequently arise in winter in high-pressure areas with low wind speeds. The problem is reduced to a two-dimensional one by vertical integration; since the highest mountains may extend into the inversion, the calculations must of course be carried out on a multi-compartment interdependent basis. The properties of the boundary layer are not taken into account in the vertical integration; only surface friction with the ground is introduced. Three comparisons are made for the three variables in the model (vertically averaged stream function, vertically averaged velocity potential and vertically averaged vorticity) and the conditions at the external and internal boundaries are defined. For the external boundaries, a distinction is drawn between the inflow and outflow boundaries of the area considered; the conditions for the former being determined by the overall (i.e. synoptic) wind conditions. As an example of application of the method, the flow pattern is calculated for the RHINE-MAIN area for an inversion height of 300 m above mean sea level. Trajectories from any chosen point can be obtained as subsidiary results and are given for 16 different overall wind directions, starting from the site of the BIBLIS nuclear power station

  1. Law concerning water and nuclear power station licensing

    The competent water authority, within the purview of the legal provisions concerning water is entitled to define a maximum of radioactive contamination of cooling water taken from and re-fed into the Rhine river, and is entitled to make such limit form part of the permit granted to a nuclear power station (here: Biblis B reactor). This right is not overruled by sections 45, 46 of the Rad. Protection Ordinance which determine dose limits (among others also for radioactivity released through waste water), and which state the competent licensing authority under atomic energy law to be entitled to set higher or lower limits by discretion. The provisions of sections 45 ff Rad. Prot. Ordinance are to be interpreted to mean that since the competent authority in accordance with section 46, sub-sections (2) and (5) Rad. Prot. Ordinance is given the right to define maximum acceptable radioactivity release through water discharge, it many also define the lowest limit of contamination and is hence entitled to declare discharged cooling water not to fall under atomic energy law, but rather under the law relating to water management.

    Since only little information is available about the extent and type of the 14C emission from nuclear facilities, the Radiation Protection and Safety Department of the Karlsruhe Nuclear Research Center has measured the 14C stack vent emission from various facilities. The measurement was restricted to 14CO2 because it is only this coumpound which can lead to exposure doses as a result of ingestion and inhalation. Sampling was carried out with 200 ml of 5 M NaOH in a scrubber. The sample flow was 1 l/min. The sampling period was one week. The 14CO2 emission was measured in the stack vent air of the FR-2 research reactor, the Multi-purpose Research Reactor (MZFR), the combustion facility for burnable radioactive waste (FERAB), the Karlsruhe Reprocessing Plant (WAK), all of which are located on the premises of the Karlsruhe Nuclear Research Center, and in the exhaust air of the Obrigheim (KWO) and Biblis A Nuclear Power Stations.

  4. Experimental investigations of pressure and temperature loads on a containment after a loss-of-coolant accident

    The phenomena occuring within a containment during a LOCA are currently investigated through experiments with a modelcontainment at Battelle-Institut Frankfurt on behalf of the Bundesministerium fuer Forschung und Technologie, Bonn. The experimental results are to be compared with the results of model calculations in order to improve the calculational methods. An experimental facility was built, consisting of a primary coolant circuit and a special model-containment. The model-containment, built in conventional reinforced concrete, has a diameter of 12 m, a height of 12.5 m, a capacity of 580 m 3 and is designed for an internal pressure of 6 bar. The interior is divided by concrete walls and removable partitions into several compartments, which are interconnected through openings with adjustable cross section. By exchanging the removable partitions it is possible to modify the interior of the containment and to simulate different containment shapes. For the first experiment a PWR-configuration with nine compartments has been istalled. The model scale of the compartment volumes and the overflow areas are about 1:64 compared to the 1,200-MW-PWR-plant Biblis A. Later investigations will also include BWR-experiments and experiments leading to an extremely high load on special containment structures. (orig.) [de

    In the LISSAC project (LImit Strains in Severe ACcidents), partly funded by the EC Nuclear Fission and Safety Programme within the 5th Framework programme, an extensive experimental and computational research programme is conducted to study the stress state and size dependence of ultimate failure strains. The results are aimed especially to make the assessment of severe accident cases more realistic. For the experiments in the LISSAC project a block of material of the German Biblis C reactor pressure vessel was available. As part of the project, eight reactor pressure vessel head models from this material (22 NiMoCr 3 7) were tested up to rupture at VTT. The specimens were provided by Forschungszentrum Karlsruhe (FzK). These tests were performed under quasistatic pressure load at room temperature. Two specimens sizes were tested and in half of the tests the specimens contain holes describing the control rod penetrations of an actual reactor pressure vessel head. These specimens were equipped with an aluminium liner. All six tests with the smaller specimen size were conducted successfully. In the test with the large specimen with holes, the behaviour of the aluminium liner material proved to differ from those of the smaller ones. As a consequence the experiment ended at the failure of the liner. The specimen without holes yielded results that were in very good agreement with those from the small specimens. (author)

  6. Conclusions drawn of tritium balance in light water reactors

    1978-01-01

    In the tritium balance of pressurized water reactors, using boric acid and lithium in the cooling water, contribution of the tritium produced by fission, diffusing through the zircalloy of the fuel cladding estimated to 0.1%, was not in agreement with quantities measured in reactors. It is still difficult to estimate what percentage is represented by the tritium formed by fission in the fuel, owing to diffusion through cladding. The tritium balance in different working nuclear power stations is consequently of interest. The tritium balance method in the water of the cooling circuit of PWR is fast and experimentally simple. It is less sensitive to errors originating from fission yields than balance of tritium produced by fission in the fuel. A tritium balance in the water of the cooling circuit of Biblis-A, with a specific burn-up of 18000 MWd/t gives a better precision. Diffusion rate of tritium produced by fission was less than 0.2%. So low a contribution is a justification to the use of lithium with an isotopic purity of 99.9% of lithium 7 to limit at a low value the residual lithium 6 [fr

  7. Structure and influence factors of fuel cycle costs of pebble bed HTRs with OTTO-fuel management

    1975-06-15

    The study in this paper can be divided into two parts. The first part deals with the analysis of the structure of the fuel cycle costs of today in 1974. A comparison is made between two pebble bed HTRs with OTTO-refueling-management (once-through) and a LWR of the type Biblis A. The two HTRs use different fuels: The one low-enriched Uranium (LOTTO), the other high-enriched Uranium and Thorium (TOTTO). The analysis of the structure of the fuel cycle costs consists of a discussion of the most important input parameters, and a comparison of each cost item. This study was made without adjustment of the core design to the changing market conditions. It is quite natural that an adaptation of the moderation ratio, of the conversion ratio, of the enrichment level, and of the burn-up may lower the fuel cycle costs. But the differences cannot be very important, and the results of this examination may remain valid, even on best adjustment conditions.

    The purpose of the present study is the presentation of the appropriate element and shape function in the solution of the neutron diffusion equation in two-dimensional (2D) geometries. To this end, the multigroup neutron diffusion equation is solved using the Galerkin finite element method in both rectangular and hexagonal reactor cores. The spatial discretization of the equation is performed using unstructured triangular and quadrilateral finite elements. Calculations are performed using both linear and quadratic approximations of shape function in the Galerkin finite element method, based on which results are compared. Using the power iteration method, the neutron flux distributions with the corresponding eigenvalue are obtained. The results are then validated against the valid results for IAEA-2D and BIBLIS-2D benchmark problems. To investigate the dependency of the results to the type and number of the elements, and shape function order, a sensitivity analysis of the calculations to the mentioned parameters is performed. It is shown that the triangular elements and second order of the shape function in each element give the best results in comparison to the other states.

  10. Insurance risk of nuclear power plant concentrations

    International Nuclear Information System (INIS)

    Feldmann, J.

    1976-01-01

    The limited number of sites available in the Federal Republic of Germany for the erection of nuclear power plants has resulted in the construction of multiple nuclear generating units on a few sites, such as Biblis, Gundremmingen and Neckarwestheim. At a value invested of approximately DM 1,200/kW this corresponds to a property concentration on one site worth DM 2 - 3 billion and more. This raises the question whether a concentration of value of this magnitude does not already exceed the limits of bearable economic risks. The property risk of a nuclear power plant, as that of any other industrial plant, is a function of the property that can be destroyed in a maximum probable loss. Insurance companies subdivide plants into so-called complex areas in which fire damage or nuclear damage could spread. While in some foreign countries twin nuclear power plants are built, where the technical systems of both units are installed in one building without any physical separation, dual unit plants are built in the Federal Republic in which the complexes with a high concentration of valuable property are physically separate building units. As a result of this separation, property insurance companies have no grounds for assessing the risk and hence, the premium different from those of single unit plants. (orig.) [de

    After the Chernobyl disaster, improvements in materials and in training were made everywhere. As a result, the quality of operation of Russian reactors now is in third place after Germany and Japan. At the present time, it is becoming more and more evident that Russia will have no future in the absence of a nuclear power industry. This is due not only to the country's geographic and socio-economic features, its large territory, and the mismatch between the major energy resources in Siberia and the centers of energy consumption in the European part of Russia, but also to the fact that there is no technology other than nuclear at present which would be able to generate the volume of electricity required after the end of the 'natural gas break'. The generation of electricity in nuclear power plants contributed from 1999 on amounted to a share of approx. 15 per cent in all of Russia; 30 per cent in the European part of Russia and in the central supply region; of this share, 60 per cent in the central Chernozem region; 41 per cent in the northwestern supply region; 70 per cent in the northwest of the autonomous Chukchen region; 40 per cent in the FOREM single electricity market. The same percentages apply to electricity exports. (orig.) [German] Nach der Katastrophe von Tschernobyl wurden ueberall Verbesserungen bei Material und Ausbildung umgesetzt.

  14. Real and mythical consequences of Chernobyl accident

    1999-01-01

    This presentation describes the public Unacceptance of Nuclear Power as a consequence of Chernobyl Accident, an accident which was a severest event in the history of the nuclear industry. It was a shock for everybody, who has been involved in nuclear power programs. But nobody could expect that it was also the end romantic page in the nuclear story. The scale of the detriment was a great, and it could be compared with other big technological man-made catastrophes. But immediately after an accident mass media and news agencies started to transmit an information with a great exaggerations of the consequences of the event. In a report on the Seminar T he lessons of the Chernobyl - 1' in 1996 examples of such incorrect information, were cited. Particularly, in the mass media it was declared that consequences of the accident could be compared with a results of the second world war, the number of victims were more than hundred thousand people, more than million of children have the serious health detriments. Such and other cases of the misconstruction have been called as myths. The real consequences of Chernobyl disaster have been summed on the International Conference 'One decade after Chernobyl' - 2, in April 1996. A very important result of the Chernobyl accident was a dissemination of stable unacceptance of the everything connected with 'the atom'. A mystic horror from invisible mortal radiation has been inspired in the masses. And from such public attitude the Nuclear Power Programs in many countries have changed dramatically. A new more pragmatic and more careful atomic era started with a slogan: 'Kernkraftwerk ? Nein, danke'. No doubt, a Chernobyl accident was a serious technical catastrophe in atomic industry. The scale of detriment is connected with a number of involved peoples, not with a number of real victims. In comparison with Bhopal case, earthquakes, crashes of the airplanes, floods, traffic accidents and other risky events of our life - the Chernobyl is

    Highlights: • Explanation for the scatter in measured fission gas release in high-BU BWR fuel rods. • Partial fuel-clad bond layer formation in high-BU BWR fuel. • Hypothesis for fission gas trapping facilitated by the pellet-cladding bond layer. • Correlation between burnup asymmetry and the quantity of trapped fission gas. • Implications of the trapped FG in LOCA transient. - Abstract: The first part of the paper presents results of a numerical analysis of the fuel behavior during base irradiation in the Kernkraftwerk Leibstadt Boiling Water Reactor (KKL BWR) using EPRI’s FALCON code coupled to GRSW-A – an advanced model for fuel swelling and fission gas release. Post-irradiation examinations conducted at the Paul Scherrer Institute’s (PSI) hot laboratory gave evidence of a distinct circumferential non-uniformity of local burnup at pellet surfaces. For several fuel samples, intact pellet-cladding bonding areas on the high burnup sides of the pellets at high burnup above ∼70 MWd/kgU were observed. It is hypothesized that a part of the fission gases, which are expected to be released by those areas, can be trapped and do not reach the rod plenum. In this paper, a simple approach to modeling of fission gas trapping is employed which reveals a potential correlation between the position of the rod within the fuel assembly (and therefore the degree of circumferential burnup non-uniformity) and the degree of fission gas trapping. A model is suggested to correlate the amount of locally trapped gas with the integral of the local contact pressure and the degree of circumferential burnup non-uniformity. The model is calibrated with available measurements of FGR from rod puncturing at the level of the plenums. In future work, the hypothesis about the axial distribution of trapped fission gas will be extrapolated to the Loss-Of-Coolant Accident (LOCA) analysis as an attempt to explain the fission gas release observed in some samples fabricated from

    1977-01-01

    For evaluation of the reliability of the safety enclosure in the case of accidents the time-dependent loads by internal pressure and temperature on the spheric steel containment and the correspondent probabilities had to be calculated. Of the spectrum of possible accidents, e.g. large LOCA which leads to a maximum pressure of approximately 4.7 bar. working of all safety systems presumed, small LOCA or rupture of a primary steam pipe, only those have been selected which result in a considerable increase of internal pressure in the safety containment. The pressure buildup in the steel containment depends roughly on the radioactive decay energy produced in the containment, on the performance of the safety systems operative after the accident and on the energy absorbed and transferred by the structural parts of the containment. For simplification the analysis of system behavior was performed in separate steps. Analysis was started by evaluation of alternate possibilities of pressure buildup depending on the function of different safety systems. Then the time dependent changes of temperature and pressure in the containment were calculated as well as the probabilities of the occurrence of the different maximum pressures. Technical data and accident event sequences describing the system analysed were taken from the PWR Biblis B, which at this time is typical for the PWR-line construction in the FRG. In order to avoid event sequences leading to complicated physical phenomena such sequences were selected which allowed well-defined description of consequences as hydrogen production by reaction of water with the Zircalloy fuel cladding or pressure buildup by CO 2 or steam generated from concrete getting in contact with the core-melt. The computer code ZOCO VI was used to calculate pressure buildup for the different event sequences. This code calculates time dependence of pressure and temperature in a multiply segmented safety containment considering accumulation and

    The first part of the analysis is concerned with the determination of the failure probability of the steel hull under internal load conditions. Two independent failure criteria are the basis for this calculation; the first one being the ultimate yield which is actually an instability condition and the second one being the fracture condition as described in Part II of the paper. Both the global and the local failure probabilities are investigated. The second part of the analysis is concerned with the external load case of earthquake. As it has already been described in Part I the probability of occurrence of a LOCA, given an earthquake has been considered in connection with the probable damage which the steel hull might experience during the earthquake. In other words the survival probability of the hull with deteriorated resistance is calculated, taking into account the frequencies of occurrence of the various events. The third part of the analysis is concerned with the reliability determination of the reinforced concrete dome structure, which is supposed to protect, the steel hull against external load conditions such as airplane crash and external pressure waves (the latter covering the load case of tornado occurrence). The reliability analysis of the reinforced concrete structure under earthquake loading is performed by utilizing the time-history method. Some aspects of the drawbacks of the response spectra method -when used in a risk analysis- are pointed out. The probability distribution of the concrete strength as determined under intermediate strain rate as described in Part II is utilized in the analysis. Finally the remaining two external load cases are discussed in light of their use in a reliability analysis and with respect to their frequency of occurrence and the probability distribution of their load intensities. The reliability demonstration is performed using the containment structure of the PWR-plant 'Biblis B' which is locate

    The report discusses the hydrogeologic settings and histories of studies associated with the Cheshire (U20n), Cambric (U5e), Nash (UE2ce), Bilby (U3cn), Bourbon (U7n), and Faultless (UC1) Events. Radionuclide and some chemical data are presented for water samples from cavity or chimney wells associated with the Cheshire, Cambric, and Bilby Events, and from satellite wells at the Cambric, Nash, Bibly, Bourbon, and Faultless Event sites. The report also gives the results of studies of specific sampling or analytical methodologies. These studies demonstrated that the apparent migration of 155 Eu is an artfact of spectrometric misidentification of gamma- and x-ray peaks from other constituents. A potential problem with atmospheric contamination of samples collected with evacuated thief samples was also identified. Ultrafiltration techniques were applied to some of the Cheshire cavity samples collected, and preliminary results suggest that substantial amounts of activity may be associated with colloidal particles in the size range of 0.006 to 0.45 μm. A study has begun of the recharge of effluent water from RNM-2S (Cambric satellite well) into the desert floor as a result of nine years of continuous pumping. This report gives the initial results of unsaturated zone studies showing the propagation of moisture and tritium fronts through the shallow soil. Geochemical modeling of the behavior of ruthenium and technetium was carried out, with particular emphasis on the identification of ionic species that would be potentially mobile under NTS ground-water conditions. The report compares the results with observations of ruthenium migration to the Cambric satellite well

  1. Possible first occurrence of external corrosion on alloy 600TT tubes in France

    During the last decade, in different countries, several occurrences of external corrosion have been identified on steam generator (SG) tube bundles equipped with thermally treated 600 alloy. In France, this feedback leads EDF to enhance the SG inspection program. Nevertheless, until now, no damage of this type was reported. Recently, during in-service inspection at the Cattenom plant on a SG equipped with alloy 600TT tubes, Eddy current tests have highlighted a signal that could be related to external corrosion. The tube was removed and sent to the EDF hot laboratory for destructive examinations. Various exams were performed at different scales to characterize the causes of this NDT signal, the material properties and the residual stresses. The assessments carried out on the tube conclude that the source of the damage is external intergranular stress corrosion cracking, also called ODSCC (Outside Diameter Stress Corrosion Cracking) making it the first occurrence on the tube bundles made of alloy 600TT in the French fleet. This first case of 600 TT ODSCC in France is an unexpected and particular one, because of its altitude in the full mechanical rolling area. This is reinforced by the low number of occurrences noted to date (only one after nearly 30 years of operation of alloy 600TT tube bundles). International (Biblis) OPEX had identified recent IGSCC with cracks initiated and propagated in the tubesheet. For this case, the scenario considered requires highly restrictive conditions (tube in the sludge zone and on the periphery of the tube bundle, including the tube lane) and may explain the singular nature of the Cattenom tube

Unsurprisingly, the biogeographic history of Indo-Pacific biota is generally poorly known, especially that of organisms found in the heart of the region, the biodiversity hotspot known as Wallacea. Here, we explore the biogeographic history of the Indo-Pacific butterfly genus Cethosia using all known species and many distinctive subspecies. Cethosia butterflies span the Indo-Pacific tropics, including several lineages with localized endemism that are critically important when reconstructing biogeographic history of the Indo-Pacific and, in particular, of Wallacea. A phylogenetic hypothesis is proposed, based on sequences of the mitochondrial genes cytochrome oxidase subunit I (COI) and NADH dehydrogenase 5 (ND5), and the nuclear wingless gene. Both Maximum Parsimony and Bayesian analyses showed that the genus is monophyletic and consistently recovered seven, generally very well supported, clades, namely the cydippe, leschenault, biblis, nietneri, hypsea, penthesilea and cyane clades. Species group relationships are largely concordant with general morphology (i.e., wing pattern and colouration) and, based on the phylogeny, we propose a revised systematic classification at the species level. The evolution of the genus appears associated with the inferred geological history of the region, in particular with respect to the expanding Wallacea theory, whereby ancient connected terranes were fragmented during the mid Miocene to early Pliocene, approximately 14-3 Mya. Recent diversification events in Cethosia were likely promoted by climatic fluctuations during the Pliocene and, to a lesser extent, the Pleistocene. Our results support the view that, while dispersal has been important for Cethosia throughout much of the region, the high levels of island endemism and the essentially allopatric radiations recovered in Cethosia in Wallacea are

    Full Text Available Introdução: A Bibliografia é uma disciplina constituída por interfaces teóricas e práticas que, desde sua origem, têm fundamentado o tratamento documental. Possui uma longa história, cuja eminência está nas contribuições do cientista, erudito e bibliógrafo suíço, Conrad Gesner (1516-1565, e na sua obra Bibliotheca Universalis.Objetivo: 1 identificar as interfaces da Bibliografia, em particular a bibliotecária e material; 2 recuperar elementos constitutivos da cultura bibliográfica; 3 delinear o perfil biobibliográfico de Conrad Gesner; 4 identificar, de forma sumária, aspectos bibliográficos de Bibliotheca Universalis, do ponto de vista descritivo e semântico e 5 discutir seu sentido como dispositivo de mediação e memória bibliográfica.Metodologia: Revisão de literatura a partir da perspectiva histórica.Resultados: Gesner é um dos mais notáveis cientistas do período moderno, além de ser considerado o “pai da Bibliografia” e fundador da disciplina bibliográfica. Com Bibliotheca Universalis, delineou as práticas bibliográficas da Europa Moderna.Conclusões: Bibliotheca Universalis é mais do que um produto cultural e documentário: arrola aspectos da cultura manuscrita e impressa e traz implicitamente uma profunda reflexão descritiva e semântica sobre os documentos e os saberes. Tais aspectos não só contribuem à configuração histórica e conceitual da Bibliografia enquanto disciplina, mas, sobretudo, evidenciam o pioneirismo bibliográfico do polímeta do Séc. XVI.

    Full Text Available O artigo apresenta o resultado de uma pesquisa cujo objetivo foi identificar as correspondências entre os fundamentos da área hoje denominada de desenvolvimento de coleções e aqueles estabelecidos no século XIX, a fim de reconstruir os principais conceitos, métodos e práticas da área. Propõe um estudo exploratório para viabilizar essa correspondência a partir de oito obras escolhidas de autores europeus do século XIX, a maioria bibliófilos reconhecidos, a saber: Peignot (1823, Namur (1834, Hesse (1841, Rouveyre (1878, Richard (1883, Gräsel (1893, Petzholdt (1894 e Maire (1896. Essas obras serão analisadas a partir de três categorias contemporâneas da área: desenvolvimento de coleções, seleção e aquisição, por meio do método de revisão de literatura. Conclui-se, por fim, que o fenômeno da explosão da informação afeta o processo de desenvolvimento de coleções como um todo desde o século XVIII. Os autores do século XIX selecionados para o estudo apresentaram várias soluções - as quais fortaleceram o que hoje é denominado de abordagem baseada no acesso à informação - para lidar com a complexidade gerada pelo fenômeno da explosão da informação.

  8. Corrosion product deposition on fuel element surfaces of a boiling water reactor

    Orlov, A.

    2011-01-01

    Over the last decade the problem of corrosion products deposition on light water reactor fuel elements has been extensively investigated in relation to the possibility of failures caused by them. The goal of the present study is to understand in a quantitative way the formation of such kind of deposits and to analytically understand the mechanism of formation and deposition with help of the quasi-steady state concentrations of a number of 3d metals in reactor water. Recent investigations on the complex corrosion product deposits on a Boiling Water Reactor (BWR) fuel cladding have shown that the observed layer locally presents unexpected magnetic properties. The buildup of magnetic corrosion product deposits (crud) on the fuel cladding of the BWR, Kernkraftwerk Leibstadt (KKL) Switzerland has hampered the Eddy-current based measurements of ZrO 2 layer thickness. The magnetic behavior of this layer and its axial variation on BWR fuel cladding is of interest with respect to non-destructive cladding characterization. Consequently, a cladding from a BWR was cut at elevations of 810 mm, where the layer was observed to be magnetic, and of 1810 mm where it was less magnetic. The samples were subsequently analyzed using electron probe microanalysis (EPMA), magnetic analysis and X-ray techniques (μXRF, μXRD and μXAFS). Both EPMA and μXRF have shown that the observed corrosion deposit layer which is situated on the Zircaloy corrosion layer consists mostly of 3-d elements’ oxides (Fe, Zn, Ni and Mn). The distribution of these elements within the investigated layer is rather complex and not homogeneous. The main components identified by 2D μXRD mapping inside the layer were hematite and spinel phases with the common formula (M x Fe y )[M (1-x) Fe (2-y) ]O 4 , where M = Zn, Ni, Mn. With μXRD it was clearly shown that the cell parameter of analyzed spinel is different from the one of the pure endmembers (ZnFe 2 O 4 , NiFe 2 O 4 and MnFe 2 O 4 ) proving the existence of

O gratuito “entre aspas” aqui enfatizado é para ressaltar que nada é gratuito, quando fala-se do universo de produção de bens e serviços. No mínimo, boa parte das pesquisas e boa parte das cátedras são remuneradas com o dinheiro da população, quando através do Estado subvenciona a realização de pesquisa científica dita pura e quando através das empresas de quem adquirem bens e serviços, subvencionam, quando estas o fazem, a realização das pesquisas aplicadas e do desenvolvimento e inovação tecnológicas.

    2003-10-01

    The local failure strains of essential reactor vessel components are investigated. The size influence of the components is of special interest. Typical severe accident conditions including elevated temperatures and dynamic loads are considered. The main part of work consists of test families with specimens under uniaxial and biaxial static and dynamic loads. Within one test family the specimen geometries and the load conditions are similar, the temperature is the same; but the size is varied up to reactor dimensions. Special attention is given to geometries with a hole or a notch causing non-uniform stress and strain distributions typical for reactor components. There are indications that for such non-uniform distributions size effects may be stronger than for uniform distributions. Thus size effects on the failure strains and failure processes are determined under realistic conditions. Several tests with nominal identical parameters are performed for small size specimens. In this way some information is obtained about the scatter. A reduced number of tests is carried out for medium size specimens and only a few tests are carried out for large size specimens to reduce the costs to an acceptable level. To manufacture all specimens sufficient material was available from the unused reactor pressure vessel Biblis C consisting of the material 22NiMoCr37. Thus variations of the mechanical material properties, which could impair the interpretation of the test results, are quite small. This has been confirmed by an adequate number of additional quality assurance tests. A key problem was the definition of failure and the determination of the local strains at failure for very different specimens under varying load conditions. Here appropriate methods had to be developed including the so-called 'vanishing gap method' and the 'forging die method'. They are based on post test geometrical measurements of the fracture surfaces and reconstructions of the related strain fields

They are based on post test geometrical measurements of the fracture surfaces and reconstructions of the related strain fields using finite element calculations, for instance. To deepen the understanding of structural degradation and fracture and to allow extrapolations, advanced computational methods including damage models have been developed and validated. Several approaches were tried in parallel including so-called non-local concepts and descriptions of stochastic properties at grain size level. The experimental results indicate that stresses versus dimensionless deformations are approximately size independent up to failure for specimens of similar geometry under similar load conditions. Also the maximum stress is approximately size independent, if failure occurs after the maximum stress is reached

    The paper presents results of a research project founded by the Swiss Federal Nuclear Inspectorate concerning the application of the Master Curve approach in nuclear reactor pressure vessels integrity assessment. The main focus is put on the applicability of pre-cracked 0.4T-SE(B) specimens with short cracks, the verification of transferability of MC reference temperatures T 0 from 0.4T thick specimens to larger specimens, ascertaining the influence of the specimen type and the test temperature on T 0 , investigation of the applicability of specimens with electroerosive notches for the fracture toughness testing, and the quantification of the loading rate and specimen type on T 0 . The test material is a forged ring of steel 22 NiMoCr 3-7 of the uncommissioned German pressurized water reactor Biblis C. SE(B) specimens with different overall sizes (specimen thickness B=0.4T, 0.8T, 1.6T, 3T, fatigue pre-cracked to a/W=0.5 and 20% side-grooved) have comparable T 0 . T 0 varies within the 1σ scatter band. The testing of C(T) specimens results in higher T 0 compared to SE(B) specimens. It can be stated that except for the lowest test temperature allowed by ASTM E1921-09a, the T 0 values evaluated with specimens tested at different test temperatures are consistent. The testing in the temperature range of T 0 ± 20 K is recommended because it gave the highest accuracy. Specimens with a/W=0.3 and a/W=0.5 crack length ratios yield comparable T 0 . The T 0 of EDM notched specimens lie 41 K up to 54 K below the T 0 of fatigue pre-cracked specimens. A significant influence of the loading rate on the MC T 0 was observed. The HSK AN 425 test procedure is a suitable method to evaluate dynamic MC tests. The reference temperature T 0 is eligible to define a reference temperature RT To for the ASME-KIC reference curve as recommended in the ASME Code Case N-629. An additional margin has to be defined for the specific type of transient to be considered in the RPV integrity assessment

  17. Field experience on Zn injection on PWR plants with a view to dose rate reduction

    International Nuclear Information System (INIS)

    Roumiguiere, F.

    2005-01-01

    Operating experience acquired at PWR plants shows that zinc injection in the primary coolant at low concentration (∼5 ppb) is a very effective tool to achieve a reduction of the dose rate build-up. The beneficial effect of zinc consists on improving the protective layer characteristics of the reactor coolant system surfaces, which results in a lower pickup of activated products (Co-60, Co-58), and consequently a reduction of the associated dose rates. Zinc injection was introduced at the Unit B of the Biblis Power Station in September 1996 and at the Obrigheim Nuclear Power Station in February 1998, as a measure for reduction of radiation fields. The effectiveness of the method and its compatibility with the overall plant was examined in a rather comprehensive surveillance program at these plants. The already published data show that zinc injection did not lead to any operating restrictions or other negative effects on plants systems and components. Zinc injection is still being implemented today at these plants. Zinc injection is considered today as a mature technique and is now being successfully applied at a number of PWRs in Germany, Brazil, USA and Japan, with the support of Framatome-ANP. Several PWRs in Europe and Asia are preparing for zinc chemistry in the near future. The method is inexpensive and easy to apply. Its implementation is highly advisable in terms of the cost/benefit criterion following the ALARA principle. This paper gives an overview of the experience gathered with the method. The main subject addressed by the paper is the evolution of dose rates at the primary system and work-related doses since introduction of the method. In German PWRs with Incoloy 800 steam generator tubing material (Ni-content ∼32%), the observed reductions correspond to a decrease in dose rates of around 10 to 15% per year following, as predicted, the half-life time of 60 Co. Overall reductions in high radiation areas are now in the range of 50% after 5 years of

    The final storage of high-level radioactive waste, which is said to be still open while, in fact, it was solved technically a long time ago and is only being blocked for political reasons, as well as alleged technical risks of German nuclear power plants which have never been demonstrated or proven, are listed again and again as grounds for opting out of the use of nuclear power. There is hardly any doubt that one of the main causes underlying also these arguments, and thus the main reason for the insufficient public acceptance of nuclear power in Germany at the present time as a safe, inexpensive, and non-polluting source of primary energy, is the widespread fear of radiation (radiophobia). Consequently, solutions proposed for successfully managing this radiophobia must be examined. Continued scientific studies of the subject do not seem to be promising, as funds are available at present only for continuing the search for negative biological effects. Important preconditions for a change in attitude are the appropriate initiatives to be taken by the relatively small number of sufficiently independent experts of proven scientific repute. Initiatives of this kind can now be observed in numerous countries and regions in the world. It must be pointed out in this connection, as is underlined again and again by experienced experts, that risk acceptance is not a matter of factual arguments, but of emotions. Psychological and pedagogic sensitivity certainly are important elements in changing public opinion in the interest of a more realistic assessment of the radiation risk and the acceptance of nuclear power.

Hochtemperaturwasser in Laborversuchen zur Untersuchung des Ermuedungsverhaltens von Staehlen zu deutlichen Effekten fuehrt. Dabei wird je nach Versuchsfuehrung entweder die Zeit bis zur Initiierung von Anrissen verkuerzt oder die Wachstumsgeschwindigkeit vorhandener Risse erhoeht. Dieser zu erwartende Einfluss des Mediums auf den Ermuedungsprozess wurde in den Anfaengen der Regulierung von Konstruktion und Auslegung von Bauteilen und Komponenten fuer Kernkraftwerke in den relevanten Regelwerken (z.B. ASME Boiler and Pressure Vessel Code, Section III) weltweit nicht explizit beruecksichtigt. Pauschal beruecksichtigt werden Umgebungseffekte dagegen in den entsprechenden da/dN-Risswachstumskurven des ASME Code, Section XI zur Bewertung des betrieblichen Verhaltens von Oberflaechenfehlern. Historisch betrachtet erfolgte in den Regelwerken die Festlegung der Vorgehensweise zur Komponentenauslegung allerdings lange vor dem gezielten experimentellen Nachweis der Umgebungseffekte auf Rissinitiierung und Risswachstum durch Ermuedung von Staehlen in Hochtemperaturwasser. Trotz dieser Erkenntnis ist es weltweit nicht zu generischen, systematischen Schaeden in Medium fuehrenden Systemen von Leichtwasserreaktoren (LWR) durch Korrosionsermuedung infolge von Fehlauslegung gekommen. Vereinzelt aufgetretene Schaeden mit deutlichen Merkmalen umgebungsbeeinflusster Ermuedungsvorgaenge konnten immer eindeutig auf das Vorkommen von unerwarteten, nicht im spezifizierten Belastungskollektiv enthaltenen Betriebstransienten zurueckgefuehrt werden. Zu diesen Ursachen zaehlen z.B. das Auftreten von thermischer Schichtung oder lokale, stroemungsinduzierte Vibrationen. In diesem Beitrag werden Ueberlegungen vorgestellt, welche die zu beobachtende Diskrepanz zwischen der diesbezueglich weltweit ueberwiegend positiven Betriebserfahrung und den Ergebnissen aus Laborversuchen mit dem

    The management of waste arising in the operation of nuclear power plants has been taken into account since the beginnings of the peaceful uses of nuclear power in Germany. As early as in 1957, a memorandum of the German Advisory Committee on Atomic Energy contains a reference to the need for safe disposal of radioactive waste. Legislation adopted the suggestion and laid down some provisions on the safe utilization of radioactive materials as early as in the Atomic Energy Act of December 23, 1959. In connection with the nuclear waste management center, the Federal Republic also looked for a suitable site for a repository. After thorough site selection proceedings by the federal government and the state of Lower Saxony, the Lower Saxony state government in 1977 defined Gorleben as the site. The decision has been preceded by a three-stage selection process in which more than 140 sites had been investigated. Exploration of the Gorleben site began in 1979 and was interrupted on October 1, 2000 to clarify conceptual and safety-related doubts of the federal government. The German Federal Ministry for the Environment (BMU) seeks to make a repository (for high-level waste) available in 2030. Technically, it is still possible to commission a repository for waste generating heat at Gorleben after 2025 if the salt dome is found to be suitable after speedy conclusion of the exploration work. Reference is made to foreseeable problem areas. Another project pursued by the federal government is the use of the Konrad mine as a repository for low and medium-level radioactive waste. After well over twenty years, the plans approval decision was made in May 2002 and is at present the subject of litigation. On the basis of the data presented about the expected arisings of waste generating no heat in combination with the possible start of emplacement in Konrad in 2013, detailed results are presented.

Diese resultierten u.a. in den Beschluessen und Auswahlverfahren der 1970er und 1980er Jahre zum Salzstock Gorleben sowie zum ehemaligen Eisenerzbergwerk Konrad als potenzielle Endlagerstandorte. Die Bundesregierung hat im Jahr 2000 fuer Gorleben ein drei- bis maximal zehnjaehriges Moratorium fuer die weiteren Erkundungsarbeiten festgelegt, um aus Sicht des Bundesministeriums fuer Umwelt, Naturschutz und Reaktorsicherheit (BMU) bestehende Zweifel abzuarbeiten. Fuer Konrad wurde im Mai 2002 ein positiver Planfeststellungsbeschluss erteilt. Nach Erlangung der Rechtssicherheit koennte ab etwa 2010-2012 die Einlagerung beginnen. Im Februar 1999 wurde der Arbeitskreis Auswahlverfahren Endlagerstandorte (AkEnd) durch das BMU berufen. Der Auftrag bestand in der Entwicklung eines nachvollziehbaren Verfahrens fuer die Suche und die Auswahl von Standorten zur Endlagerung aller Arten radioaktiver Abfaelle in Deutschland. Das vom AkEnd abschliessende vorgestellte Verfahren birgt erhebliche Unsicherheiten, u.a. bezueglich der rechtlichen Umsetzbarkeit, des erforderlichen Zeitbedarfs und der Finanzierung. Es koennen sich mit Blick auf den Salzstock Gorleben allein durch zusaetzliche Erkundungen und Verfahren Mehrkosten gegenueber der Weiterfuehrung der Projekttaetigkeiten in Hoehe von 3 bis 5 Mrd. Euro ergeben. Aehnlich hohe Mehrbelastungen - insbesondere fuer die oeffentliche Hand - sind bei einer Verzoegerung der Einlagerung in Konrad zu erwarten. Eine moeglichst zuegige Endlagerung aller Abfallarten in tiefen geologischen Formationen ist unter sicherheitstechnischen Aspekten anderen Alternativen vorzuziehen. Daher sollte unter Beruecksichtigung aller Faktoren eine weitere Erkundung von Gorleben zuegig abgeschlossen und das Projekt Konrad realisiert werden. (orig.)

    Gruenen nach der Bundestagswahl von 1998 wurde zur Entsorgung der deutschen Kernkraftwerke ein von der bis dahin angestrebten Praxis abweichender Weg vereinbart. Unter anderem soll nur ein einziges Endlager in tiefen geologischen Formationen etwa ab dem Jahr 2030 zur Verfuegung stehen. Die Erkundung des Salzstockes Gorleben soll aufgrund bestehender Zweifel unterbrochen werden bei paralleler grundsaetzlicher Diskussion zu potenziell geeigneten Wirtsgesteinen und Standorten. Der von der Bundesregierung einberufene 'Arbeitskreis Auswahlverfahren Endlagerstandorte (AkEnd)' soll mit diesen Vorgaben wissenschaftliche Standortkriterien erarbeiten. Die Autoren, Mitglieder des AkEnd, kommen aufgrund von fachlichen Erkenntnissen sowie der historisch gewachsenen Entsorgungs- und Standortsituation in Deutschland zu dem Schluss, dass ein Mehr-Endlager-Konzept substanzielle Vorteile aufweist. Folgende Aspekte werden dafuer genannt: - Entsorgungskonzeption: Das Mehr-Endlager-Konzept bietet mit dem weit fortgeschrittenen Endlagerprojekt Konrad eindeutige Vorteile. Dies auch vor dem Hintergrund der von der oeffentlichen Hand zu bewaeltigenden Menge an Abfaellen mit vernachlaessigbarer Waermeentwicklung. - Langzeitsicherheit: Vorteile, u.a. im Hinblick auf sicherheitstechnische Aspekte bezueglich der moeglichen Kompromisse bei einem Ein-Endlager-Konzept und der moeglichen Einschraenkung der Anzahl potenzieller Standorte, liegen vor. - Nachweisverfahren: Es liegen nachweistechnische Vorteile bei Aufteilung der Abfaelle auf zwei oder mehr Endlager vor. - Kosten: Eine differenzierte Betrachtung der Kosten fuer alle endzulagernden Abfaelle deutet auf Vorteile - insbesondere fuer die oeffentliche Hand - bei einem Mehr-Endlager-Konzept hin.

    . É um avanço? É a busca pela construção de uma resposta da qual os profissionais do campo da informação não podem se escusar? Talvez! Esse talvez se explica pelo fato de que aqueles mesmos bibliotecários, liderados pelo Conselho Regional de Biblioteconomia da 8ª Região, mantêm uma seqüência dessas reuniões, que prosseguirão por todo o ano de 2005. Também constitui desafio atual ao campo a modalidade de publicação periódica em meio eletrônico, do que esta revista Encontros Bibli é um dos canais tecnologicamente beneficiados e, porisso, está sendo analisada em seus aspectos intrínsecos e extrínsecos. Como análises de outros veículos no meio impresso oferecidas pela literatura, um estudo sobre um periódico publicado em meio eletrônico traz uma avaliação que contribuirá para alavancar e fortalecer o campo da informação, na razão direta em que fatores relacionados à autoria e produtividade também abrem questões que, mais adiante, apontarão para a avaliação da qualidade com que o campo da informação produz o seu discurso. Permite verificar com quem os autores do campo dialogam no universo uni, inter, multi e transdisciplinar e que matrizes importam e formulam para sustentar seu conhecimento explicativo e prático e, assim, a sua ciência e a sua tecnologia. É neste aspecto que o discurso plural se manifesta mais e mais e nesta edição vai estar representado por artigos que resultam do encontro intelectual de cientistas da informação e cientistas na computação, praticando, propondo e experimentando possíveis respostas que levam a possibilidades mais amplas de armazenamento e recuperação da informação. De outro lado, revelam também uma certa impossibilidade de geração desse conhecimento tecnológico insulado em um espaço particular de tratamento da informação ou em uma organização de pesquisa.

Este número especial da Revista Encontros Bibli apresenta artigos sobre o tema “A Cognição em Ciência da Informação: relação entre Psicologia Cognitiva, Cognição, Ciência da Informação. Paradigma Cognitivo na CI”. A Ciência da Informação tem incorporado novas abordagens que permitam o aprimoramento do diálogo entre os sujeitos buscando proporcionar ferramentas para uma maior interação entre as unidades de informação e a prática dos seus profissionais em permanente interação com os usuários. Nesse sentido, o objetivo é incentivar estudos que promovam conexões entre os sistemas de informação e sujeitos na busca da informação. Para efetuar essa função, a ciência da informação dialoga necessariamente com as áreas do conhecimento que visam a estudos relativos à comunicação humana de modo geral, especificamente organização, representação e uso da informação. A cognição humana em Ciência da Informação é especialmente importante haja vista ser o conhecimento a base em que se alicerçam aspetos fundamentais para a compreensão dos processos de organização, representação, gestão e uso da informação. Compreender o processamento humano em contextos que se realizam a organização, representação e uso da informação enriquecem e consolidam os demais estudos de Ciência da Informação, pois o ser humano em suas relações e inter-relações é uma fonte natural, fidedigna e preciosa de informações e conhecimentos. Nessa perspectiva, os editores da Revista Encontros Bibli pretendem, com este número especial, dar enfoque a produção científica que contemple a inter-relação entre Cognição e Ciência da Informação. Além disso, busca-se também incentivar um maior número de estudos que contemplem o conjunto de

Una de las bibliotecas más importantes del siglo XVII fue la de don Lorenzo Ramírez de Prado, erudito y bibliófilo, que reunió en su casa madrileña por lo menos unos 8.951 volúmenes. Quizás la especial relación que tuvo don Lorenzo con América a lo largo de su vida –fue ahijado del humanista Pedro de Valencia, cronista de Indias; fue Consejero de Indias desde 1626 hasta su muerte, como también lo fue su hermano Alonso; otro de sus hermanos, Marcos, fue obispo de Michoacán, etc.–, influyó en que entre los fondos de su biblioteca se encuentren las principales obras de tema americano y algunas editadas en el Nuevo Mundo. En este trabajo pretendemos, tras el examen exhaustivo del inventario, ofrecer una relación de los registros del fondo americano (tema americano y obras impresas en América que existían en la librería en el momento en que se inventarió, seguido del análisis y las conclusiones de este.

Zinc injection now has become a mature method and is now being successfully applied at several old design, co containing PWRs in Germany, Brazil and US. Several PWRs in Europe and Asia are preparing for zinc chemistry in the near future. The method is inexpensive and thus also attractive in terms of the cost/benefit criterion of the ALARA principle. In Germany, Zinc injection for reducing radiation fields was introduced first at Unit B of Biblis NPP in September 1996 and at Obrigheim NPP in February 1998. Zinc injection is still being implemented today at these plants. This paper gives an overview of the experience acquired with this method. The main topic addressed in this paper is the evolution of dose rates at the primary system and work-related doses since introduction of the zinc chemistry. Reductions in high dose rate areas have meanwhile achieved values of 40 to 50%. Annual collective doses per man-hour spent in the controlled access area of the plant as well as personal doses for specific activities are also decreasing

Além disso, é necessário desenvolver várias atividades de gestão da informação e do conhecimento, sem as quais não é possível propiciar as condições adequadas para a aplicação da inteligência organizacional ou competitiva. Nessa perspectiva, a gestão da informação e do conhecimento são os pilares da inteligência competitiva e, como tal, também são essenciais para sua efetividade. Este número especial da revista Encontros Bibli congrega alguns artigos que exploram desde os conceitos até modelos e metodologias aplicados à inteligência organizacional ou competitiva. O primeiro artigo ‘Inteligência organizacional: conceitos, modelos e metodologias’ apresenta as principais semelhanças e diferenças entre os conceitos ‘inteligência organizacional’ e ‘inteligência competitiva’, bem como apresenta alguns modelos utilizados no contexto empresarial destacando suas limitações. O texto ‘Gestão do conhecimento e inteligência competitiva: delineamento de estratégias de

    The 'Ersatz Kernkraftwerk Beznau AG' (EKKB) Company submitted to the Swiss Federal Inspectorate of Nuclear Safety (ENSI) a request for a general license for a new power plant to be built near to the Beznau power plants. According to the law, all damage risks with a probability higher than 10 -4 /a must be taken into account through protection measures. The considered risks concern the power plant itself as well as the population in the neighbourhood and the environment. The purpose of the general license is to demonstrate that the site chosen for the foreseen power plant is acceptable and that the risks can be counteracted through adequate measures. The buildings of the power plant and their partition on the Beznau Island in the Aare River are briefly described. The reactor is a Light Water Reactor of third generation with a maximum electrical power of 1450 MW el ±20%. The main cooling is provided by a hybrid system of water evaporation and air heating, what reduces the plume at the exit of the cooling tower. First, it is demonstrated that, in the case of a very unlikely severe accident in the power plant, the people in the neighbourhood can be evacuated quickly. Then, numerous types of possible accidents in the neighbourhood of the power plant are analyzed in order to settle their possible negative influence on the operation of the power plant: bursting of gas containers on the neighbouring roads and railways, fires of all types of hydrocarbons, air pollution through chloride gas, etc. The check by ENSI of the EKKB studies on the potential danger for the power plant through neighbouring industrial plants, roads or railways demonstrated that none of the considered accidents presents an unacceptable risk for the power plant: on the one hand, these plants are located too far from the power plant, so that a sensible injury to the power plant safety can be excluded; on the other, the protection of the power plant can be guaranteed through appropriate technical

According to the law, all damage risks with a probability higher than 10{sup -4}/a must be taken into account through protection measures. The considered risks concern the power plant itself as well as the population in the neighbourhood and the environment. The purpose of the general license is to demonstrate that the site chosen for the foreseen power plant is acceptable and that the risks can be counteracted through adequate measures. The buildings of the power plant and their partition on the left side of the Aare River are briefly described. The reactor is a Light Water Reactor of third generation with a maximum electrical power of 1.6 GW{sub el}. The European Pressurized water Reactor, which is of the same power class, can be taken as an example for planning that will follow. The main cooling is provided by one or, if needed, two cooling towers using a hybrid system of water evaporation and air heating, what reduces the plume at the exit of the cooling towers.

    Full Text Available EDITORIAL Al contrario que en la mayoría de los países europeos y americanos (tanto del norte como del sur, la formación en el área de Biblioteconomía y Documentación tiene una escasa tradición en la universidad española. De hecho, sólo hace 20 años que de las universidades de Barcelona y Granada salieron los primeros titulados universitarios en Biblioteconomía y Documentación. En 1978 se habían creado legalmente en España las Escuelas y Diplomaturas universitarias en Biblioteconomía y Documentación, pero no fue hasta el curso 1983/84 cuando empezó su andadura en estas dos universidades, que actuaron de pioneras. Dado que este primer título era de 3 años, en 1986 salieron de ambas universidades los primeros Diplomados en Biblioteconomía y Documentación. Y tuvieron que pasar otros cuantos años, para que en 1994 la formación fuera ampliada con la creación de un segundo ciclo (Licenciatura, que suponía dos años más de estudio. Finalmente, en 1996 se concedió el primer título de doctor en Documentación y se generalizaron los programas de doctorado específicos del área de Documentación. Es decir, sólo a partir de la segunda mitad de los noventa se puede considerar que la formación universitaria queda completada y se dan las condiciones mínimas para un adecuado desarrollo de la investigación en este área en España. Aunque el periodo transcurrido ha sido muy corto, la investigación en este campo ha experimentado un gran crecimiento, tanto en cantidad como calidad, siguiendo un patrón similar al del conjunto de la investigación en España, cuyo desarrollo en la década de los noventa ha sido sobresaliente, debido tanto al desarrollo económico del país como a los incentivos que se implantan a partir de finales de los años ochenta.

A abordagem é recorrente no texto de Silvana Drumond Monteiro que, ao expor sua Semiótica peirciana e a questão da informação e do conhecimento apresenta a diferença entre informação e conhecimento, tanto do ponto de vista da linguagem, como do sujeito cognoscente. No artigo Signos audiovisuais e ciência da informação: uma avaliação, Jalver Bethônico também se ampara nas reflexões de Charles Sanders Peirce para concluir pela compreensão do fenômeno da informação através da análise nos mais variados tipos de textos que são materializados em distintas formas simbólicas destacando que o saber é ato de conhecer sob o ponto de vista daquele que o interpreta. Na expectativa de oferecer um outro foco para a parceria da Ciência da Informação com a Semiótica, Celia Regina Simonetti Barbalho, no texto Fazer semiótico: subsídios para Enc. Bibli: R. Eletr.

    Full Text Available A comunicação científica tradicional enfrenta uma série de barreiras que dificultam não apenas a publicação dos resultados de pesquisas, como também o seu acesso por parte da comunidade científica. Entre essas dificuldades, destacam-se: 1 alta excessiva no custo das assinaturas de revistas científicas; 2 longo prazo para a efetiva publicação de determinado artigo; 3 os direitos autorais são entregues gratuitamente aos editores científicos, os únicos a ganhar em toda a cadeia da comunicação científica. A convergência tecnológica propiciou alternativas que podem derrubar parte dessas barreiras. Uma das alternativas que as tecnologias da informação e da comunicação propiciaram é o modelo de interoperabilidade denominado Arquivos Abertos (Open Archives. Em conseqüência, surge o movimento em prol do acesso livre à informação científica (Open Access. A experiência da conjugação dessa base tecnológica com o movimento do Acesso Livre à Informação Científica é o tema deste número especial da revista Encontros Bibli. As contribuições de especialistas brasileiros e estrangeiros para esta edição trazem um enfoque variado sobre este tema. Iniciamos com uma entrevista com Stevan Harnad, um dos principais líderes do movimento do Acesso Livre à Informação Científica. Nessa entrevista, Stevan comenta sobre o papel do modelo de interoperabilidade Open Archives no movimento Acesso Livre à Informação Científica, falando sobre o futuro desse movimento e as suas estratégias para implantar o acesso livre à informação científica em todo o planeta. O artigo “Comunicação científica: o papel da Open Archives Initiative no contexto do Acesso livre” aborda a questão do acesso livre, relacionando-a ao uso de tecnologias de auto-arquivamento e à publicação em periódicos eletrônicos que seguem a filosofia dos arquivos abertos como uma reação aos editores científicos comerciais.
