Texte intégralRésumé :
Germany announced on 30 May 2011 that it will shut down all of its 17 nuclear power stations by 2022 (8 of them immediately, the others step by step), which makes Germany become the first developed country in the world that totally give up the nuclear power and fulfill the change of energy structure after the Fukushima nuclear accident in Japan. The paper analyses the political, economic, social and technical aspects of this decision and its consequences for Germany and its possible impact worldwide.

Texte intégralRésumé :
Nuclear waste management is a contested challenge that lasts for decades. Especially in Germany, the history of the usage of nuclear energy is conflictive and notions of justice are therefore omnipresent in the ongoing site selection process for a nuclear waste repository. Against the background of injustices caused by the deployment of nuclear energy, such as the obligation for current generations to deal with nuclear waste, questions of how to justly deal with nuclear waste and to find a just repository site arise. By conducting a survey among people that participate in the site selection process as well as people living in or representing an area that is still considered suitable, the assessment of different aspects of justice was evaluated. The role of a science-informed site decision without any political bias is considered highly important for a just site selection. Distributional aspects, such as notions of utilitarianism, retribution, or the exemption of environmentally burdened regions are generally not approved but more detailed questions have shown that such notions cannot be dismissed at this early stage of the site selection process. The difference for general agreement can also be observed for intergenerational recognition, as the recognition of future generations is regarded as necessary, but concrete implications (retrievability or enclosure) are assessed ambiguously. Although some factors of justice are assessed more importantly than others, the analysis has shown that the interrelations between the different dimensions of justice are manifold and the argument that one dimension can be substituted for another one is too reductive.

Texte intégralRésumé :
Abstract. Since 2013 the site search for a repository for highly radioactive waste has been taking place in Germany within the framework of a new governance architecture and under new political guidelines. Based on experiences with nuclear politics in the past, Jungk (1977) coined the term hard nuclear state, characterized by decisions made in a top-down manner. The Decide-Announce-Defend (DAD) strategy, which branded the nuclear state at that time, led to conflicts, mistrust of authorities and blockages. In particular, massive resistance developed against the planned final repository site at Gorleben. Nowadays, after more than 60 years deploying nuclear energy, the (energy) political balance of power has fundamentally changed. Parts of the anti-nuclear movement have been integrated into the political party system and have contributed significantly to the nuclear phase-out. In the course of this, the unfinished task of final disposal has been readdressed: with the Repository Site Selection Act (StandAG, 2017), which was passed in 2013 and amended in 2017, an ongoing process of public participation is stated. The site selection process is required to be learning, self-questioning, science-based, reversible, and participatory. The StandAG § 5 not only provides a basis for a fundamental dialogue between the regulator, the operator, and the public, but also for „co-design“ by common citizens. The StandAG considers various elements from different participation-friendly theories of democracy as well as specific governance concepts, which we refer to collectively as the soft nuclear repository state (cf. Brunnengräber, 2021). Its characteristics need to be worked out, as the StandAG only provides some indications, but no criteria, for what good and sufficient participation in the site selection process means and what its conditions for success should be. Based on preliminary considerations on democratic theory and governance aspects (part 1), we present what good participation could mean in the current procedure and what the framework conditions for good participation could be (part 2). Additionally, we present main findings from participatory observations from the ongoing site search process and identify conditions and indications of a successful future participation process based on the ongoing process (part 3). In the résumé, we turn to the question of which of the democracy-theoretical elements of the soft repository state are already recognizable in the present procedure, but also whether the current procedure provides additional indications towards the soft nuclear repository state (part 4).

Texte intégralRésumé :
Постановка задачи. Семантико-когнитивный метод анализа языка как способ исследования концептов представляет интерес, поскольку позволяет выявить когнитивные признаки концепта на широком и репрезентативном материале. В настоящем исследовании заявленный метод представлен в части, касающейся анализа лексикографических данных и когнитивной интерпретации контекстов употребления лексем номинативного поля Atomkraft в немецком языке. Целью статьи является установление когнитивных признаков лексем номинативного поля Atomkraft , кодифицированных в словарях и выявляемых в ходе анализа корпуса текстов публикаций в СМИ и блогах в период с 1980 по 2014 гг., для последующего построения полевой модели концепта. Особый интерес представляет влияние произошедших в данный период техногенных катастроф в секторе ядерной энергетики (ЯЭ) на частотность употребления и семантику обозначенных лексических единиц. Результаты. На основании анализа словарных статей, а также привлечения репрезентативного корпуса текстов устанавливается, что доминантным когнитивным признаком концепта является «отказ от ядерной энергетики», наиболее широко представленный лексемой Atomenergie . Общая полевая структура концепта с учетом всех номинативных единиц выглядит следующим образом: ядро составляет признак «отказ от ядерной энергетики» (31%); ближнюю периферию - «политические аспекты» и «опасности ЯЭ» (31%); дальнюю периферию - «вопросы экологии» и «будущее ЯЭ» (17%); крайнюю периферию - «ЯЭ как одна из проблем современности» и «мирное использование ЯЭ» (9%). Выводы. Дискуссионным продолжает оставаться вопрос о наличии корреляции между частотностью употребления лексических единиц рассматриваемого поля и происходящими в мире техногенными катастрофами. В рамках представленного исследования не было выявлено достоверных свидетельств подобной взаимосвязи. В ходе работы установлено, что пик употребления лексических единиц номинативного поля приходится на 2008-2009 гг., когда в Германии проходила подготовка и проведение предвыборной кампании в парламент, что позволяет сделать предположение о большем влиянии политической обстановки на семантическое наполнение концепта. Данная проблема, однако, требует дальнейших исследований на расширенном корпусе текстов. Statement of the problem. The semantic-cognitive method of language analysis as a means of studying concepts is of interest, because it allows one to identify the cognitive attributes of the concept on a wide and representative material. In the present study, the claimed method is presented in part regarding the analysis of lexicographic data and the cognitive interpretation of the contexts of the use of Atomkraft nominative field lexemes in German. The purpose of the article is to establish the cognitive features of the Atomkraft nominative field lexemes, codified in dictionaries and revealed during the analysis of the text corpus of publications in the media and blogs from 1980 to 2014, for the subsequent construction of a field model of the concept. Of particular interest is the effect of technological disasters in the nuclear energy sector that occurred during this period on the frequency of use and semantics of designated lexical units. Results. Based on the analysis of vocabulary entries, as well as the involvement of a representative text corpus, it is established that the dominant cognitive feature of the concept is “rejection of nuclear energy”, the most widely represented by the token Atomenergie . The general field structure of the concept, taking into account all nominative units, is as follows: the core is a sign of “abandonment of nuclear energy” (31%); the near periphery - “political aspects” and “dangers of nuclear power” (31%); the far periphery - “environmental issues” and “the future of nuclear power” (17%); the outer periphery - “nuclear power as one of the problems of our time” and “peaceful use of nuclear energy” (9%). Conclusion. The question of whether there is a correlation between the frequency of use of the lexical units of the field in question and the technological disasters occurring in the world continues to remain debatable. In the framework of the presented study, no reliable evidence of such a relationship was revealed. In the course of the work, it was found that the peak of the use of lexical units of the nominative field occurred in 2008-2009, when preparations for and pre-election campaigns were held in Germany, which suggests the greater influence of the political situation on the semantic content of the concept. This problem, however, requires further research on an expanded corpus of texts.

Arbatov, A. « The Nuclear Agreement with Iran : Exception or Precedent ? » World Economy and International Relations 60, no 3 (2016) : 5–15. http://dx.doi.org/10.20542/0131-2227-2016-60-3-5-15.
Texte intégralRésumé :
The article deals with the Agreement concluded in July of 2015 by the group of states “5+1” (the United States, Russia, Britain, France, China and Germany, and special envoy of the European Union) with Iran on its nuclear energy program (called Joint Comprehensive Plan of Action – JCPOA). It is argued, that despite some controversial points the Agreement as a whole is tangibly limiting, reducing and restructuring Iranian nuclear-technical assets, its development program, stockpile and quality of nuclear materials, and is prohibiting potentially military activities. Of special value is the broad and deep regime of transparency, safeguards and control by the International Atomic Energy Agency (IAEA), which goes much further than the existing safeguards associated with the Non-Proliferation Treaty (NPT). It is underlined that objectively (regardless of Iranian intentions) manufacturing of nuclear weapon or some secret military activity of significant scale is practically out of question in Iran during the term of various provisions of the Agreement (10–25 years). As proved by the article, a crucial factor in reaching the JCPOA were the U.S. and European Union economic and financial sanctions, adopted against Iran in 2012. They led to the profound economic crisis, which brought the change of government at presidential elections of 2013, and eventually facilitated Iranian concessions (foremost, on the scale of uranium enrichment, deep underground enrichment complex, plutonium-producing reactor, and the scale of transparency). On the other hand, in contrast to American and Russian official statements, the unprecedented tensions between Russia and the West around the Ukrainian crisis since the early 2014 seriously weakened the unity and diplomatic dominance of the “5+1” group of states. Hence, it turned impossible to achieve still more far-reaching agreements on some principle issues (in particular, on the necessity for Iran to receive the approval of the “5+1” and IAEA for the parameters of its nuclear energy program justifiable by peaceful needs – as suggested by the Interim Agreement of November 2013). This has created a precedent for other states to claim the right for developing nuclear energy programs with dual purpose or suspicious elements without obligatory and plausible peaceful justification. It is also underlined, that the future impact of the Agreement on the global system and regimes of nuclear non-proliferation is unclear. The positive side is the JCPOA role in preventing the new war in the Gulf. The dubious aspect is that universalization of the limitations and transparency norms of the Agreement for the purpose of the Non-Proliferation Treaty enhancement is rejected by a number of states, foremost by Russia. It keeps to a tough position that the Agreement is exceptionally Iranian case, which is not applicable to other states, and in fact this point is legally fixed in JCPOA and IAEA documents. This Russian position is in line with its general stance against more restrictive interpretation of the NPT norms and against more intrusive IAEA safeguards. No doubt, in the foreseeable future, these issues will be a matter of serious controversies among states regarding the enhancement of the NPT and overall non-proliferation system and regimes.

Texte intégralRésumé :
The article analyses economic roots of the recent reassessment of the role of nuclear energy in the EU with the global economic crisis as a background. Despite the huge political impact caused by Fukushima disaster the majority of EU member states don’t commit to nuclear power phase-out or to a major curb of nuclear development. This can be explained by the high economic viability of NPPs’ operation as well as by huge monetary expenses and environmental consequences associated with the phase out. Most openly this can be seen in the case of Germany.

Texte intégralRésumé :
This article analyzes the role of the state in the development of, and controversy over, civilian nuclear energy in West Germany. The static and uniform categories of state strength and state weakness are found insufficient to account for the capacity or incapacity of the state to formulate and implement nuclear policy. Instead, the analysis uncovers the existence of conflicting and contradictory models of statehood in postwar German politics. They shaped the particular contours of nuclear development and conflict.

The institutionalization of ecological attitudes in highly industrialized societies is the main interest of this study. Analyses of national politics often underestimates the competing and partially latent interests which are voiced by different political pressure groups. Therefore, I am interested in the response of the workers' movement to the ecological challenge. Although the labor movement does not support the cruder forms of ecologism such as no-growth claims, of all established political actors it is the most open to these demands. This is so because the ecological politics offers an utopia for a modern society. The labor movement has also the aspiration of being a socially progressive force of society that aims for social change. Most directly, the left-wing parties have to compete with other parties that attract the post-material electorate. However, the policy and strategy of workingclass parties are not independent of trade union policy. It is self-evident that politicians of social democratic parties consult trade unions in order to formulate their political goals. But also on the national policy level, unions are often consulted in order to obtain a broad alliance for some political decisions. All these examples should illustrate that trade union policy and standpoints concerning the development of society are important for the better understanding of the political outcomes of society. Yet traditional union policy - and also trade union research - tends very much to generally ignore politics: "Unions are involved in a major way in a very significant activity - the political life of the country - and yet there is considerable evidence that they do not take that activity very seriously".

This thesis compares the French and British Chernobyl debates in the period between 1986 and 2006 and investigates the transnational debate on the health effects of this accident. While the exchange of actors and arguments has resulted in a rather congruent debate at the transnational level, the internal country debates on Chernobyl have remained very much bound by the national framework. This becomes particularly obvious in the comparison of the French and British Chernobyl debates, where multiple factors, specific to the national context, have shaped the different trajectories of the debates. In France, from the outset, Chernobyl was framed as a French debate, and placed into the context of the nucleócratie. In Britain, such an interpretative framework did not exist for the civil nuclear programme, since the predominant criticism against the nuclear enterprise had always been directed against the military complex and more focused on aspects of international relations than on the national nuclear energy complex. In Britain, therefore, Chernobyl was considered from a global perspective, whereas in France the focus was placed on the accident's impact at home. However, with the end of the Cold War and the British government's decision in the mid-1990s to no longer finance new nuclear power plants, anti-nuclear positions as such lost their impetus. Thus, few people in Britain were interested transforming the debate on the health impact of Chernobyl into a proxy war in the fight over the legitimacy of the civil nuclear enterprise, as was happening in France. Leaving this discursive and commemorative gap to the solidarity movement, in Britain, Chernobyl did not become an anti-nuclear lieu de mémoire as it did in France, but instead became associated primarily with charity activities for disabled or unprivileged children from Eastern Europe which effectively 'depoliticized' Chernobyl and separated it from the nuclear debate.

Texte intégralRésumé :
In the previous chapter, the malleability of Danish energy policy was highlighted as a key factor behind the successful diffusion of wind power in Denmark. This chapter examines wind power diffusion in Germany, and in the process highlights a different, though equally successful policy ideology. Compared to policy of its Nordic neighbor, wind power development policy in Germany has been far more structured and invariable. In fact, the success of Germany’s wind power development strategy often serves as an exemplar for proponents of consistent feed-in tariff regimes, which is considered by some to be the most effective strategy for driving wind power development. As this chapter will demonstrate, fostering wind power development in Germany is, like in other nations, a complex challenge involving dynamic interactions between government and nongovernment actors. As German wind power capacity expanded, there has been social dissent and utility opposition. Nevertheless, the German government has remained committed to aggressive wind power diffusion policies and has responded to emergent challenges in a remarkably unified manner wherein state, regional, and local government actors have formed integrated problem-solving networks. This chapter also highlights the seamless web of nation-specific STEP factors influencing wind power development that is apparent in Germany. As one pair of researchers observed, wind power development in Germany has been marked by “close interplay between the actors within the political system, technical and economic development, as well as social factors.” As has been the case in most industrialized nations, forces in support of wind power development began to amass during the two energy crises of the 1970s. As the government began to evaluate its alternative energy technology options, nuclear power and wind power emerged as the two most viable utility-scale options. In the 1970s, nuclear power in Germany enjoyed a modicum of developmental success. The nation’s first commercial nuclear power plant commenced operation in 1969. By 2010, nuclear power contributed approximately 22% to Germany’s electricity supply. However, nuclear power development has been contentious. Although there has been industrial support, there has also been strident public opposition, especially since Chernobyl.

Texte intégralRésumé :
In Germany, altogether 19 nuclear power plants (NPPs) and prototype reactors have been permanently shut down. For 15 NPPs the dismantling is in progress with “green-field conditions” as planning target. Two units were completely dismantled and two are in safe enclosure. The main legal provision for all aspects of the peaceful use of nuclear energy in Germany is the Atomic Energy Act (AtG), which also contains the basic legal conditions for the decommissioning of nuclear facilities. It stipulates that decommissioning is subject to a licence by the regulatory body of the respective Federal State (Land). An emerging decommissioning practice in Germany is the removal of complete undismantled large components and their transport to interim storage facilities. During the period of storage, the radionuclide inventory of the components will decrease due to radioactive decay and the subsequent segmentation of the components can be done with less radiation protection effort. The commissioning of the Konrad repository in the near future might have consequences on planning of decommissioning, regarding the selection of a decommissioning strategy and the waste management.

Texte intégralRésumé :
To fully understand a technological development one must appreciate social, political and economic factors in addition to the technological components (Hughes, 1991). The systems perspective, asserted by Hughes, implies that technologies cannot be understood in isolation, but only in their contexts, especially in their systemic contexts. This theory is illustrated through an examination of France’s implementation of its nuclear power program in the early 1970’s. Nuclear power provided France with the opportunity to achieve energy independence and, as a result, political control over its energy supply. The scope of this case study is limited to consideration of the socio-technical influences on the rise of nuclear power in France and includes an examination of the technical aspects of the innovation. In considering the socio-technical system encompassing France’s adoption of nuclear power, this case study will contemplate: how France was able to persuade its people to accept nuclear power; what it is about French culture and politics that allowed them to succeed where most other countries have failed; the break throughs that led to the broad commercialisation of nuclear power in France in the 1970’s; and how France achieved its status as one of the world’s top producers of nuclear energy. The time period during which this study is based is limited to the early 1970’s, when France was reliant upon external energy supplies, up until the present day, where nuclear power has become France’s main source of energy, thus contributing to France’s autonomy in terms of its energy supply. This study will not address the issue of nuclear waste or the nuclear power safety debate which is also beyond the scope of this study.

Texte intégralRésumé :
It is broadly accepted that current energy systems should become more sustainable in both a global and local context. However, setting common goals and shared objectives and determining the appropriate means by which to get there is the subject of heavy debate. Therefore, the American Society of Mechanical Engineers (ASME) and the German Association of Engineers (VDI) initiated a joint project aimed at providing a young engineers’ perspective to the global energy conversation. The young engineer project teams set a common goal of assembling a completely sustainable energy system for the U.S. and Germany by 2050. This includes not only the electricity market, but the overall energy system. Based on the current global energy paradigm, a completely sustainable energy system seems very ambitious. However, multiple analyses show that this path is possible and would in the medium to long run not only be desirable, but also competitive in the market. This future ‘energy puzzle’ consists of many important pieces, and the overall picture must be shaped by an overarching strategy of sustainability. Besides the many detailed pieces, four main critical issues must be addressed by engineers, politicians and everybody else alike. These challenges are: i) Rational use of energy: This uncomfortable topic is rather unappealing to communicate, but is a key issue to reduce energy demand and to meet the potentials of renewable energy carriers. ii) Balancing of electricity demand and generation: This is a challenge to the electricity markets and infrastructures that are currently designed for base-load, mainly fossil power plants. The overall mix of renewable energy generation, storage technologies, grid infrastructure, and power electronics will decide how efficient and reliable a future energy system will be. iii) Cost efficiency and competitiveness: It is a prerequisite for industrialized countries to stay competitive and to establish RE in the market. Developing economic technologies while at the same time establishing a strong RE market is the secret of success. iv) Acceptance of the system and its consequences: The best energy strategy cannot be realized without broad public acceptance for it. Therefore, the understanding of the energy technologies and an objective discussion must be promoted — without old fashioned emotionalizing of certain risks. The paper will present details on the four mentioned aspects, compare the situations between the U.S. and Germany, and propose solutions for appropriate political frame conditions to achieve a sustainable energy system.

Texte intégralRésumé :
The ultimate disposal of high-level radioactive waste (HLW) becomes a hard issue for sustainable nuclear energy in Japan especially after Fukushima Daiichi accident. In this paper, the difficulty of realizing underground HLW disposal in Japanese islands is first discussed from socio-political aspects. Then, revival of old idea of deep seabed disposal of HLW in Pacific Ocean is proposed as an alternative way of HLW disposal. Although this had been abandoned in the past for the reason that it will violate London Convention which prohibits dumping radioactive wastes in public sea, the author will stress the merit of seabed disposal of HLW deep in Pacific Ocean not only from the view point of more safe and ultimate way of disposing HLWs (both vitrified and spent fuel) than by underground disposal, but also the emergence of new marine project by synergetic collaboration of rare-earth resource exploration from the deep sea floor in Pacific Ocean.

Texte intégralRésumé :
There are two categories of requirements: (i) user requirements that need to be met by the designers and manufacturers of innovative reactors and fuel cycles, and (ii) a wide spectrum of requirements that need to be met by countries, willing to successfully deploy innovative nuclear reactors for energy production. This part of the International Project on Innovative Reactors and Fuel Cycles will mainly deal with the second category of requirements. Both categories of requirements will vary depending on the institutional development, infrastructure availability and social attitude in any given country. Out of the need for sustainable development requirements will also more specific in the future. Over a 50-year time frame both categories of requirements will evolve with social and economic development as nuclear technology develops further. For example, the deployment of innovative reactors in countries with marginal or non-existing nuclear infrastructures would be possible only if the reactors are built, owned and operated by an international nuclear utility or if they are inherently safe and can be delivered as a “black box - nuclear battery”. A number of issues will need to be addressed and conditions and requirements developed if this is going to become a reality. One general requirement for wider utilization of innovative nuclear power will be the public and environmental considerations, which will play a role in the decision making processes. Five main clusters of topics will be handled: • Infrastuctural aspects, typology and consequences for nuclear development. • Industrial requirements for the different innovative concepts. • Institutional developments and requirements for future deployment of nuclear energy. (National as well as international). • Socio-political aspects, a.o. public acceptance and role of governments. • Sustainability: requirements following the need for sustainability. Analysis will be made of the evolution of national and international social, institutional and infrastructure requirements for the deployment of innovative nuclear technology through 2050 and beyond and requirements will be identified following the need for.

Texte intégralRésumé :
Nowadays, decommissioning of nuclear power plants has become a key issue for nuclear industry in Europe. The phasing out of nuclear energy in Germany, Belgium and Sweden, as well as the early closure of nuclear units in applicant countries in the frame of EU enlargement, has largely contributed to consider decommissioning as the next challenge to face. The situation is slightly different in France where nuclear energy is still considered as a safe, cost-effective and environment friendly energy source. Electricite´ de France (EDF) is working on the development of a new generation of reactor to replace the existing one and erection of a new nuclear power plant could start in the next few years. Nevertheless, to achieve this objective, it will be necessary to get the support of political decision-makers and the acceptance of public opinion. Due to the growing concern of these stakeholders for environmental issues, their support can only be obtained if it is possible to demonstrate that nuclear energy industry will not leave behind unsolved issues that will be a burden to the next generations. In this context decommissioning of the first generation of EDF NPPs constitutes a prerequisite for the erection of a new type of nuclear power plant. This paper will present the programme defined by EDF for the decommissioning of its nine already shutdown reactors (Fig. 1). The reasons of the recent evolution of EDF decommissioning strategy will be explained and the key issues that will contribute to the successful implementation of this programme will be addressed. Finally, what has been achieved on sites so far and major planned activities will be described.

Dans 2018 26th International Conference on Nuclear Engineering. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/icone26-81578.
Texte intégralRésumé :
The phase–out of all Nuclear Power Plants (NPP) until 2022 in Germany offer the opportunity to apply new and efficient decommissioning technologies, which allow further reduction of decommissioning costs and minimization of the collective dose for personnel. One challenging task in this process is the decontamination of protective paints containing polychlorinated biphenyl (PCB). PCB-containing surfaces demand consecutive radiological decontamination and removal of the PCB-containing paints before the demolition is possible. Laser technology, commonly used in many different industrial sectors, presents an advanced approach to this problem. Successful thermal decomposition of PCB-containing paints using high power diode lasers has been reported by our group in former publications [1]. Ongoing investigations focus on the technology transfer from static laboratory state to industrial application. This includes the verification of safety and efficiency issues for the complete laser supported process. The current presentation covers all aspects of the laser process: concrete sample preparation as well as an experimental set-up utilizing a mobile laser system that includes an innovative laser head. Particular focus will be on the phenomena of the generated concrete surfaces and the arising by-products during laser processing. A 10 kW high power diode laser, Laserline LDF 1500-10000 was used for the ablation experiments. Concrete samples were coated with typical decontamination epoxy-based paints, which match the commonly used paint systems in German NPPs in terms of composition, structure and thickness. The influence of significant processing parameters (laser power, feed rate, type of concrete and composition of paint) on the laser ablation are shown in relation to the energy input per length. The release of particles is subjected to these parameters as well. Therefore the size and the shape of the arising particles have been measured online in accordance with these processing parameters by an Engine Exhaust Particle Sizer (EEPS, Model RP-3090, TSI) in a range between 5.6 to 560 nm. The quantity of particles has also been counted by a Condensation Particle Counter (CPC, Model 3022, TSI). Overall up to 6 million particles per cubic decimeter are detected with a dilution factor of 1:100 throughout the experiments. Both measuring systems are connected to the exhaust air pipe downstream, next to the laser head. The shift of the particle size in accordance with the above mentioned parameters is crucial for a comprehensive understanding of the laser decontamination. The mobile laser supported decontamination technology will be tested in 2018 in a German nuclear facility. This test will contain the decontamination process with actual surface configurations like floors, walls, ceilings and corners, and will act as an effective proof-of-concept for the developed laser system prototype.

Texte intégralRésumé :
Up to the end of this decade, corresponding to the planned date of starting operation in the final disposal KONRAD for non-heat generating waste in Germany, a lot of efforts are needed to condition and package the radioactive waste in containers certified by BfS (Federal Institute for Radiation Protection). This waste is produced by public sector and industry as well as nuclear energy facilities, which result in more than a half of the actually declared quantity growing especially after the phase out decision of nuclear power production in Germany and the subsequent decommissioning of nuclear power plants. BAM (Federal Institute for Materials Research and Testing) acts as responsible authority on behalf of BfS for design testing under consideration of the KONRAD requirements. Within the assessment procedure of containers, BAM has to verify the application documents, including material qualification, container geometry, corrosion protection, leakage rate and operational and accidental loading, and to evaluate quality assurance measures. Besides the previous completed approvals for various containers such as steel sheet and cast iron box-shaped containers and concrete cylindrical ones, BAM is actually carrying assessments for other types such as cast iron cylindrical containers and “old” steel sheet box shaped ones. The so called “old” containers present already loaded containers without any KONRAD certification, currently stored at licensed interim storages. In the benefit of the container assessment, BAM operates design testing facilities for drop and fire tests which are also used for research objectives to improve and expand the evaluation methods such as research project ConDrop. The latter deals with numerical simulations and analyses tools for further precise predictions about unfavorable drop test scenarios, safety margins, and design sensitivities for steel sheet containers. Furthermore, during the assessment procedure, several specifications about the containers, the inventory to be disposed and the required safety level have been intensely debated by authorities and applicants. Based on its experience in qualifying containers, BAM has been commissioned to identify insufficiently specified aspects in the waste acceptance criteria and to propose clearer definitions with regard to the secondary regulations in the planning approval notice. This paper focuses on aspects of the contribution of BAM in certifying KONRAD waste containers. This will include the current state of design testing procedures, evaluation methods that are available or are being developed and the main topics within the KONRAD requirements being actually specified by BAM.

Texte intégralRésumé :
Amidst the clamor and increasing world demand for energy, the continued use of fossil fuels for electric power generation has recently emerged as the bane of the industry. Green power is being championed as the new fuel de jour kid on the block. Environmentalists and other global warming advocates are successfully lobbying their political agendas for emission caps, carbon sequestration, NOx and SOx and other greenhouse gas limits. In many cases, these efforts have resulted in the outright cancellation, delay or unit reductions of new coal-fired plants. Similarly, simple and combined cycle gas turbine (CCGT) units, popularized during the Enron “gas bubble” era are at the mercy of unstable fuel prices which have, in large part, relegated this generation type from base load to load follow. Wind, biomass, hydro, photovoltaic and other renewables continue to produce an increased percentage of the power base but total contribution remains costly, inefficient and pitifully low. Enter the nuclear renaissance. A dramatic paradigm shift, even by the green power advocates, has allowed the nuclear phoenix to rise with the promise of emission-free power, generation efficiencies, increasing ROI revenues and demonstrating an enviable safety record since TMI and Chernobyl. Assuming this energy source conceives and bears the gestated fruit of a renaissance, the next decade will be telling in terms of the challenges brought forward by licensing, design, financing, construction and operation of a new generation of nuclear power reactors. Paramount among these is a new, time-tested generation of construction materials that will be evaluated to insure a 40 to 60 or even 80 year operational life of these new plants. Consider the problematic copper materials that were chosen during the early 70’s for their high thermal conductivity, competitive cost and ease of fabrication. Contrast these past lessons-learned to current-day, state-of-the-art generation fleet construction standards where demonstrated long-term sustainability coupled with state-of-the-art designs & materials must emerge as the prominent industry players of choice. The paper will examine these and other relevant aspects of the technical and commercial supply chain that is predicted to both challenge and reward designers and material suppliers well into the next decade.

Texte intégralRésumé :
There are basic technical (protection) objectives determined for assurance of nuclear power plant safety and the following generally belong among them: - Reactor pressure vessel shut down, - Long term maintenance of sub-critical state, - Long term cooling, - Prevention of radioactivity leakage. To ensure these objectives multi-step concept of deep protection is used for the design of a nuclear power plant and it includes: - Prevention of failures during normal and abnormal operation, - Control of failures and their consequences, - Minimizing of risks during accidents. Failure of operating systems is conservatively postulated for determination of systems requirements using for failure ensure as piping breaks. Ensure of these postulated failures come under multilevel safety approach. Failure consequences should be mainly ensured by design measures as separation of high energy piping, whip piping restrains etc. Efficiency of design measures have to be demonstrated. This passive safety procedure during design of new NPP can be applied. Application of this passive procedure for operating NPP can lead to technical and economical problems. It can be done by non precise and non sufficient requirements, current standards and documents. Leak before break concept (LBB) is very often out due to break operation conditions for successful concept usage. Beak preclusion concept was defined in Germany thirty years ago. The concept is developed from this time. Required quality of SSC is basic of this concept. The quality has to be received during manufacturing and assembly of new components to system or the quality passport has to be documented for SSC in operation before enlistment to the concept. During next operation they are sufficient and redundant measures necessary to control and to manage ageing phenomena (conceptual, technological, and physical) for exclusion of premature ageing. This proactive approach is also basic of documents from the last year’s required ageing and lifetime management. In Czech NPPs postulated failures and their consequences in accord with producer knowledge state at that time were insured. Postulated failures and their consequences were insured partly design measures and partly design supposed quality too. It is very difficult to realize new requirements on needed design provision on NPP in operation. It is impracticable in any cases. Needed national law for approach application exists in Czech from 1997. Regulation on lifetime management and national nuclear standards with specific requirements exist in Czech too. There are backgrounds for application proactive approach as it is used in Germany NPPs. New safety approach was provided in Czech NPPs. SSC are separated into three groups on the base safety approach: - SSC must not fail (guarantee of quality), - SSC may fail in rare case (preventative maintenance), - SSC may fail (failure orientated maintenance). The contribution deals about new Czech safety concept aspects, boundary conditions, needed document and proactive measures.
