    A first part is devoted to the description of the interaction phenomena between elementary particles and material that may be observed during the irradiation process in a nuclear reactor: nuclear reactions due to neutrons, production of gamma rays and absorption of those gamma rays through various processes. In a second part the phenomena producing calorific energy in irradiated material are quantitatively examined. In the third part results are summed up in a formulary. The fourth part presents tables and figures giving to the reader all the numerical values necessary for practical calculations.

    After recalling the entry of nuclear energy into energy production in France, the paper emphasizes the evolution of techniques applied in the designing of French nuclear power plants and describes the means employed for reducing costs per kWh of EDF2 and EDF3 compared with EDF1: the electric power per ton of uranium varies from 493 kW/t for EDF1 to 970 kW/t for EDF3. For this purpose the thermal power and electric power of units are changed respectively from 290 MWt for EDF1 to 1200 or 1600 MWt for EDF3 and from 28 to 250 MW. The results are obtained by an improvement in neutronic characteristics, developments in nuclear fuel technology, and simplification of the system of charging the reactor, whose means of maintenance are increased; the EDF2 heat-exchangers have been so designed as to increase the unit power of the elements, which will attain 9 MWt, as against 3 for EDF1. For EDF3 an advance project forecasts a thermodynamic layout with only one pressure stage. The paper ends with a description of the burst-slug detection systems, and an appendix gives a detailed comparative table of EDF1, EDF2 and EDF3 plant characteristics. (author) [French] Apres avoir rappele l'integration de l'energie nucleaire parmi les moyens de production de l'energie en France, les auteurs se penchent surtout sur l'evolution des techniques appliquees dans l'equipement des centrales nucleaires francaises et decrivent les moyens mis en oeuvre pour reduire les prix de revient du kWh d'EDF2 et d'EDF3 par rapport a EDF1: la puissance electrique par tonne d'uranium varie de 493 kW/t pour EDF1 a 970 kW/t pour EDF3. C'est dans ce but que les puissances thermiques et la puissance unitaire des groupes turbo-alternateurs passent respectivement de 290 MWt pour EDF1 a 1200 ou 1600 MWt pour EDF3 et de 82 a 250 MW.

    The different meanings of the word 'energy', as understood by economists, are reviewed and explained. Present rates of consumption of fossil and nuclear fuels are given as well as corresponding reserves and resources. The time left before exhaustion of these reserves is calculated for different energy consumption scenarios. On finds that coal and nuclear only allow to reach the end of this century. Without specific dispositions, the predicted massive use of coal is not compatible with any admissible value of global heating. Thus, we discuss the clean coal techniques, including carbon dioxide capture and storage. One proceeds with the discussion of availability and feasibility of renewable energies, with special attention to electricity production. One distinguishes controllable renewable energies from those which are intermittent. Among the first we find hydroelectricity, biomass, and geothermal and among the second, wind and solar. At world level, hydroelectricity will, most probably, remain the main renewable contributor to electricity production. Photovoltaic is extremely promising for providing villages remote deprived from access to a centralized network. Biomass should be an important source of bio-fuels. Geothermal energy should be an interesting source of low temperature heat. Development of wind energy will be inhibited by the lack of cheap and massive electricity storage; its contribution should not exceed 10% of electricity production. Its present development is totally dependent upon massive public support. A large part of this paper follows chapters of the monograph 'L'energie de demain: technique, environnement, economie', EDP Sciences, 2005. (author)

    France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

    Experiments in nuclear physics involve the use of large size 'memories'. After showing the difficulties arising from the use of such memories, the authors give the principles of the various programming methods which make it possible to operate the memories associatively thus benefiting from a reduction in size and better operational conditions. They attempt to estimate the shape and dimensions of an associative memory with cable connections which could be designed specially for nuclear research, contrary to those actually in service.

Ils tentent d'evaluer le format d'une memoire associative cablee qui, contrairement a celles qui existent actuellement, serait prevue specialement pour l'experimentation nucleaire. (auteurs)

    The present report gives an overview of the present facilities of energy productions in France and their perspectives. the electric production comes for half about power stations hydraulics and for half of thermal power stations. However due to the increase of the energy consumption, France is particularly interested by the atomic energy that appears to bring a supply in due time to the hydraulics and to limit a development of the thermal power stations to which the natural resources of France in classic fuel would not permit to cope presumably. The integration of the nuclear plants to the other production facilities will make itself gradually according to the evolution of the energy needs. (M.B.) [French] Le present rapport donne un apercu des moyens actuels de productions energetiques en France et de ses perspectives. la production electrique provient pour moitie environ de centrales hydraulique et pour moitie de centrales thermiques. Cependant face a l'augmentation de la consommation energetique, la France est tres particulierement interessee par l'energie atomique qui parait devoir apporter en temps utile la releve a l'hydraulique et limiter un developpement des centrales thermiques auxquels les ressources naturelles de la France en combustible classique ne permettraient vraisemblablement pas de faire face. L'integration des centrales nucleaires aux autres moyens de production se fera graduellment en fonction de l'evolution des besoins energetiques. (M.B.)

    Louisiana Energy Services (LES) was founded in June, 1989, on the premise that the US uranium enrichment services market requires an alternative domestic source of supply, which would be both highly reliable and economically competitive. LES is comprised of the operating company of a partnership among subsidiaries of three US utilities, an engineer-constructor, and an enricher (Urenco). The US partners hold in the aggregate a majority share. LES will begin delivering to US customers in 1996 using a process well proven in european practice. LES submitted a license application to the US Nuclear Regulatory Commission (USNRC) for the Claiborne Centrifuge Enrichment Center on schedule and within budget, and they have accepted it for review. LES expects to receive that license at the end of 1992, although the achievement of that schedule will require diligence of both LES and the NRC. LES was very pleased that the US Congress passed an amendment to the Atomic Energy Act specifically allowing them to apply for a combined license for construction and operation, thus removing what is currently one of the most serious obstacles to successful completion of nuclear power plant projects. It is clear that the progress of licensing will be watched by the nuclear industry as a sign of how new plant applications will fare in general

    For all moderators of the 'incoherent gaussian' type, it is possible to calculate, at any temperature, the energy transfer moments as a function of the incident energy without having to use the differential sections. Integral formulae are derived for the integral cross-section, the first and the second moment, which make it possible to tabulate directly these three functions in a few minutes calculation on IBM 7094, for the most part models proposed in the literature for the common moderators.

    This debate is based on a study recently published by Ifri's Energy Program (Les relations franco-allemandes dans le secteur de l'energie, by Jan Horst Keppler, Sophie Meritet and Kristina Notz). Franco-German energy relations are often dominated by debates on nuclear power and, for many observers, the two countries seem far apart on this question. Indeed, very different political decisions have been made by either country on the issue. Surprisingly, opinion polls have shown that public opinion on nuclear energy is quite similar in both countries. Furthermore, the cooperation between Areva and Siemens in the nuclear field is one of the best examples of Franco-German industrial cooperation. In more general terms, France and Germany have a quite different energy mix and hence both countries have divergent positions concerning some aspects of European energy policy. Positions on nuclear energy phasing-out, electricity networks, energy security and gas supply, fuel substitution, climate change and the development of renewable energy sources, etc. are discussed

    One of the economic advantages of nuclear energy consists of the small proportional element in its cost structure. Economies of scale favour the nuclear station as compared with the conventional thermal one, and when the demand for electricity and heat, in particular for desalination, are sufficient, nuclear energy may, subject to certain conditions, prove advantageous. The object of this paper is to discuss the validity of the conclusions reached according to the hypotheses adopted. In the first part, the different kind of uncertainties connected with technical, economic and financial data (the various transmission coefficients, the life of equipment according to the choice of materials, changes in prices, the form of price functions and interest rates), and with the various constraints, are examined and discussed. In the second part the uncertainties connected with the method of optimisation used and the criterion of selection adopted are examined and discussed. It is shown thereby that it is usually extremely difficult to assume absolutely the competitiveness, or conversely the non-competitiveness, of using nuclear energy in the desalination of water, and that a large number of aspects have to be carefully examined. (author) [French] On sait que l'un des avantages economiques de l'energie nucleaire reside dans la faible part proportionnelle dans la structure de son cout. Les economies d'echelle favorisent le nucleaire par rapport au thermique classique, et lorsque les demandes d'electricite et de chaleur, notamment pour le dessalement, sont suffisantes on peut envisager favorablement, sous certaines hypotheses, le recours a l'energie nucleaire. L'objet de cette communication est de discuter la validite des conclusions auxquelles on parvient selon les hypotheses envisagees. Dans une premiere partie, on etudie et on discute les differentes sortes d'incertitudes, liees aux donnees techniques, economiques et financieres (les divers coefficients de transmission, les

Its part in the field has recently found expression in the creation, within the Biology Department, of a Radio-agronomy Section; its objective are described,, as well as the, means placed att its disposal at the Centre d'etudes Nucleaires, Cadarache. (author) [French] On propose un bilan des travaux les plus significatifs effectues en France depuis la deuxieme conference internationale en matiere d'agronomie nucleaire et qui vont d'une recherche apparemment desinteressee a l'application la plus directe. Une telle differenciation recouvre de moins en moins, au fur et a mesure de l'evolution des programmes, la distinction qui est faite dans l'expose entre l'action biologique des rayonnements et les autres emplois des techniques nucleaires. C'est ainsi que les recherches do radiogenetique agricole sont poursuivies dans deux directions: d'un point de vue theorique et methodologique avec l'etude comparative de l'action des divers types de rayonnements, l'influence du debit de dose et de la temperature, l'action des agents mutagenes chimiques, la production de chimeres sous irradiation gamma; et d'autre part, sous un aspect pratique aboutissant a la creation de varietes nouvelles plus resistantes ou plus precoces (riz, mil, arachide). Les problemes de destruction des insectes (eradication) et de conservation des denrees sous irradiation se trouvent egalement abordes par des voies et avec des objectifs tres divers. A la demarche globale representee par une irradiation pure et simple (grains humides, pommes de terre...) sont parfois associees des etudes souvent originales, d'ordre biochimique ou microbiologique (par exemple: alteration de l'amidon, metabolisme glucidique des tubercules irradies, radioresistance des levures

    Dumont, Ariane

    Il a ete demontre que les electrons de basse energie (EBE) peuvent induire des cassures simple brin (CSB) a l'ADN, via la formation d'anions transitoires qui decroissent par attachement dissociatif, ou dans d'autres etats electroniques dissociatifs menant a la fragmentation. Afin d'effectuer une etude complete des effets des electrons de basse energie sur la matiere biologique, il est necessaire de comprendre leur mecanismes d'interaction non seulement avec l'ADN, mais avec les constituants de son environnement. Les histones sont une composante importante de l'environnement moleculaire de l'ADN. Leur charge positive leur permet de s'associer aux groupements phosphate anionique de l'ADN. Le role principal de ces proteines basiques consiste a organiser l'ADN et l'empaqueter afin de former la chromatine. Les cations sont une autre composante importante de la cellule; ils jouent un role dans la stabilisation de la conformation B de l'ADN in vitro par leurs interactions avec les petits et grands sillons de l'ADN, ainsi qu'avec le groupement phosphate charge negativement. Avec les histones, ils participent egalement a la compaction de l'ADN pour former la chromatine. Cette etude a pour but de comprendre comment la presence d'ions organiques (sous forme de Tris et d'EDTA) a proximite de l'ADN modifie le rendement de cassures simple brin induit par les electrons de basse energie. Le Tris et l'EDTA ont-ete choisis comme objet d'etude, puisqu'en solution, ils forment le tampon standard pour solubiliser l'ADN dans les experiences in vitro (10mM Tris, 1mM EDTA). De plus, la molecule Tris possede un groupement amine alors que l'EDTA possede 4 groupements carboxyliques. Ensembles, ils peuvent se comporter comme un modele simple pour les acides amines. Le ratio molaire de 10 :1 de Tris par rapport a l'EDTA a pour but d'imiter le comportement des histones qui sont riches en arginine et lysine, acides amines possedant un groupement amine charge positivement additionnel.

The energy sector in France is dominated by 4 companies: EDF, GDF-Suez, Areva and Total, all are strongly pro-nuclear. All the political parties except EELV (Europe-Ecology-Les-Verts) are favourable to nuclear energy. Most non-governmental organizations are favourable to renewable energies, but the FED (Federation Environnement Durable) gathers local associations fighting the installations of wind turbines. (A.C)

    France has placed itself in a very peculiar, unprecedented situation regarding its energy policy, for it is now at the same time: part of a minority of countries in the world that have developed to a great extent a nuclear industry for the production of electricity - and indeed France has gone further than any country in that direction, reaching an almost 80% share of nuclear energy in the national production of electricity (second world-wide behind Lithuania) and a total 62,4 G We installed capacity of nuclear power plants (second behind the United-States); part of a minority of countries among democratic nations that is governed by a coalition including strong opponents to the use of nuclear energy for the production of electricity with participation of the French main Green Party (called Les Verts) in the Government. This produces important changes, if not yet in all decisions over French energy policy, at least in the declarations of the different players and the orientations of the political and public debates. Also some policy implementation measures have had profound impact on the long term nuclear policy making. (author)

    In order to calculate the energy of solution of rare gases in metals, a method which has given good results in the case of solid solutions in metals has been applied. Nevertheless, it was necessary for this, to know the compressibility of gases under conditions which are not feasible in a laboratory. H. Jensen has studied this compressibility in a precise way for the rare gases Ar, Kr, Xe. It has thus been possible to calculate the energy of solution of these gases in different metals. These calculations have been carried out most thoroughly for the case of uranium.

(author) [French] On propose un bilan des travaux les plus significatifs effectues en France depuis la deuxieme conference internationale en matiere d'agronomie nucleaire et qui vont d'une recherche apparemment desinteressee a l'application la plus directe.

C'est ainsi que les recherches do radiogenetique agricole sont poursuivies dans deux directions: d'un point de vue theorique et methodologique avec l'etude comparative de l'action des divers types de rayonnements, l'influence du debit de dose et de la temperature, l'action des agents mutagenes chimiques, la production de chimeres sous irradiation gamma; et d'autre part, sous un aspect pratique aboutissant a la creation de varietes nouvelles plus resistantes ou plus precoces (riz, mil, arachide). Les problemes de destruction des insectes (eradication) et de conservation des denrees sous irradiation se trouvent egalement abordes par des voies et avec des objectifs tres divers.

  8. Dispersion modeling of atmospheric contaminants in the Angra Nuclear Power Plant using LES and a new model for the CBL growth

    Moreira, Davidson M.; Goulart, Antonio G.; Soares, Pedro M.; Vilhena, Marco T.

    2009-01-01

    In the present work we report a comparison between experimental data and GILTT approach to simulate radioactive contaminant dispersion in the Atmospheric Boundary Layer using micrometeorological parameters generated by LES (Large Eddy Simulation) in the area around the Angra dos Reis Nuclear Power Plant. Furthermore, starting from the evolution equation for the turbulent energy density spectrum (EDS), we develop a new model for the growth of the turbulence in Convective Boundary Layer (CBL). We apply dimensional analysis to parameterize the unknown inertial transport and convective source term in the dynamic equation for the three-dimensional (3-D) spectrum. The non linear integro-differential equation is solved by Adomian decomposition method. The one-dimensional vertical spectrum is derived from the 3-D spectrum, employing a weight function. This allows us to select the magnitude of the vertical spectral component for the construction of the growing 3-D. Using the micrometeorological parameters generated by LES, for the first time, we employ the vertical component of the energy spectrum to calculate the eddy diffusivity (required in dispersion models). This new eddy diffusivity is used in the simulations of the ground-level concentrations considering experimental data of the Nuclear Power Plant. (author)

    This article begins with a review of the various materials which can be used and the cooling gases in which they may be heated, emphasis being placed on the importance of reaching temperatures as high as possible. This is followed by a few general remarks on the dry oxidation of metals and alloys, particularly with regard to diffusion phenomena and their various possible mechanisms, and also the methods of investigation employed. Finally, the behaviour of the chief nuclear materials heated in the various gases is studied successively. Materials used for fuel (metallic uranium, uranium oxide, carbides and silicides), canning materials (magnesium, aluminium, zirconium, beryllium, stainless and refractory steels), structural materials (ordinary or slightly alloyed steels), and finally moderators (graphite, beryllium oxide) are deal with in this way. This account is backed up both by the results obtained at the CEA and by work published outside or abroad up to the present day. In conclusion, every effort has been made to direct future research on the basis of the foregoing. Reprint of a paper published in Industries Atomiques - no. 9/10, 1959, p. 3-23 [French] Dans cet article, on passe tout d'abord en revue les divers materiaux utilisables et les gaz de refroidissement dans lesquels ils peuvent etre chauffes, en insistant sur l'interet d'atteindre des temperatures aussi elevees que possible.

    Do Georgia needs nuclear energy? Nuclear energy is high technology and application of such technology needs definite level of industry, science and society development. Nuclear energy is not only source of electricity production - application of nuclear energy increases year-by-year for medical, science and industrial use. As an energy source Georgia has priority to extend hydro-power capacity by reasonable use of all available water resources. In parallel regime the application of energy efficiency and energy conservation measures should be considered but currently this is not prioritized by Government. Meanwhile this should be taken into consideration that attempts to reduce energy consumption by increasing energy efficiency would simply raise demand for energy in the economy as a whole. The Nuclear energy application needs routine calculation and investigation. For this reason Government Commission is already established. But it seems in advance that regional nuclear power plant for South-Caucasus region would be much more attractive for future

    A concept to produce hydrogen of an energy carrier using nuclear energy was proposed since 1970s, and a number of process based on thermochemical method has been investigated after petroleum shock. As this method is used high temperature based on nuclear reactors, these researches are mainly carried out as a part of application of high temperature reactors, which has been carried out at an aim of the high temperature reactor application in the Japan Atomic Energy Research Institute. On October, 2000, the 'First International Conference for Information Exchange on Hydrogen Production based on Nuclear Energy' was held by auspice of OECD/NEA, where hydrogen energy at energy view in the 21st Century, technology on hydrogen production using nuclear energy, and so on, were published. This commentary was summarized surveys and researches on hydrogen production using nuclear energy carried out by the Nuclear Hydrogen Research Group established on January, 2001 for one year. They contains, views on energy and hydrogen/nuclear energy, hydrogen production using nuclear energy and already finished researches, methods of hydrogen production using nuclear energy and their present conditions, concepts on production plants of nuclear hydrogen, resources on nuclear hydrogen production and effect on global environment, requests from market and acceptability of society, and its future process.

    Full text of publication follows: The turbulence modelling is an important issue concerning the predictive capability of the CFD codes applied to nuclear reactor safety (NRS), in particular for single-phase flows. Common features of these unsteady high Reynolds number turbulent flows are various regimes (laminar, transitional, fully turbulent) developing in arbitrary complex geometries involving a large extend of standard flow configurations (attached and detached boundary layers, mixing layers, jets in cavity, in cross flows, jet impingement) eventually submitted to buoyancy forces, to dilatation effects and leading to mixing of constituents and temperatures. NRS issues are most of the time related to the eventual knowledge of parietal quantities such as temperature (mean and fluctuating), leading to consider the wall region as a crucial one and to deal with coupled problems. All these features can lead to consider different approaches for turbulence modelling: more or less standard 'Reynolds Average Navier-Stokes equations' closures, Large Eddy Simulations, both of them considered with or without wall functions, with or without large implicit time stepping etc. The development and industrialization of LES as a target of providing 'reference simulations' for NRS are parts of the Trio-U project, developed at CEA for several years [1]. First, the paper presents the current status of LES implementation and some insights on the R and D effort concerning the turbulence modelling. The R and D strategy will be introduced as a result of both the extra-nuclear community know-how on LES and several years of applications of LES for nuclear issues at CEA. It will be shown that LES can be considered as a good candidate to deal with the previous mentioned issues. A large emphasis will be devoted to the R and D on approximate wall conditions, including first the checking of the consistency of standard and advanced wall conditions with LES approach, second specific works dealing

    Do we need nuclear energy. Is it safe. What are the risks. Will it lead to proliferation. The questions are endless, the answers often confused. In the vigorous debates that surround the siting and operation of nuclear power plants, it is all too easy to lose sight of the central issues amid the mass of arguments and counter-arguments put forward. And there remains the doubt, who do we believe. This book presents the facts, simply, straightforwardly, and comprehensibly. It describes the different types of nuclear reactor, how they work, how energy is produced and transformed into usable power, how nuclear waste is handled, what safeguards are built in to prevent accident, contamination and misuse. More important, it does this in the context of the real world, examining the benefits as well as the dangers of a nuclear power programme, quantifying the risks, and providing an authoritative account of the nuclear industry worldwide. Technically complex and politically controversial, the contribution of nuclear energy to our future energy requirements is a crucial topic of our time. (author)

    Today we know two forms of nuclear energy: fission and fusion. Fission is the decomposition of heavy nuclei, while fusion is the melting together of light nuclei. Both processes create a large surplus of energy. Technologically, we can currently only use fission to produce energy in today's nuclear power plants, but there is intense research worldwide in order to realize a controlled fusion process. In a practical context, today's nuclear energy is a sustained source of energy since the resource base is virtually unlimited. When fusion technology is realized, the resource supply will be a marginal problem. (AG)

    We all want to prevent the use of nuclear weapons. The issue before us is how best to achieve this objective; more specifically, whether the peaceful applications of nuclear energy help or hinder, and to what extent. Many of us in the nuclear industry are working on these applications from a conviction that without peaceful nuclear energy the risk of nuclear war would be appreciably greater. Others, however, hold the opposite view. In discussing the subject, a necessary step in allaying fears is understanding some facts, and indeed facing up to some unpalatable facts. When the facts are assessed, and a balance struck, the conclusion is that peaceful nuclear energy is much more part of the solution to preventing nuclear war than it is part of the problem

    Energy is the power of the world's economies, whose appetite for this commodity is increasing as the leading economies expand and developing economies grow. How to provide the energy demanded while protecting our environment and conserving natural resources is a vital question facing us today. Many parts of our society are debating how to power the future and whether nuclear energy should play a role. Nuclear energy is a complex technology with serious issues and a controversial past. Yet it also has the potential to provide considerable benefits. In pondering the future of this imposing technology, people want to know. - How safe is nuclear energy? - Is nuclear energy economically competitive? - What role can nuclear energy play in meeting greenhouse gas reduction targets? - What can be done with the radioactive waste it generates? - Does its use increase the risk of proliferation of nuclear weapons? - Are there sufficient and secure resources to permit its prolonged exploitation? - Can tomorrow's nuclear energy be better than today's? This publication provides authoritative and factual replies to these questions. Written primarily to inform policy makers, it will also serve interested members of the public, academics, journalists and industry leaders. (author)

    This nuclear energy roadmap has been prepared jointly by the IEA and the OECD Nuclear Energy Agency (NEA). Unlike most other low-carbon energy sources, nuclear energy is a mature technology that has been in use for more than 50 years. The latest designs for nuclear power plants build on this experience to offer enhanced safety and performance, and are ready for wider deployment over the next few years. Several countries are reactivating dormant nuclear programmes, while others are considering nuclear for the first time. China in particular is already embarking on a rapid nuclear expansion. In the longer term, there is great potential for new developments in nuclear energy technology to enhance nuclear's role in a sustainable energy future.

    2006-01-01

    In the early 1970s, Patrick Moore, a co-founder of Greenpeace, believed that nuclear energy was synonymous with nuclear holocaust. Thirty years on, his views have changed because nuclear energy is the only non-greenhouse-gas-emitting power source that can effectively replace fossil fuels while satisfying the world's increasing demand for energy. Today, 441 nuclear plants operating globally avoid the release of nearly 3 billion tonnes of CO 2 emissions annually-the equivalent of the exhaust from more than 428 million cars. Concerns associated with nuclear energy are discussed including costs of nuclear energy, safety of nuclear plants, radioactive waste management, vulnerability of nuclear plants to terrorist attacks and diversion of nuclear fuel for weaponization. It is concluded that nuclear energy is the best way to produce safe, clean, reliable baseload electricity, and will play a key role in achieving global energy security. With climate change at the top of the international agenda, we must all do our part to encourage a nuclear energy renaissance

The survey was carried out without handicaps according to the brain-storming principle. Although the results cannot claim to be representative, they certainly reflect the areas of interest of many citizens and also their expectations, hopes and fears in connection with nuclear energy. The greater part of the questions were aimed at three topic areas: The security of nuclear power-stations, the effects of radioactivity on people and the problem of waste disposal. The book centres around these sets of questions. The introduction gives a general survey of the significance of nuclear energy as a whole. After this follow questions to do with the function of nuclear power stations, for the problems of security and waste disposal - which are dealt with in the following chapters - are easier to explain and to understand if a few physical and technical basics are understood. In the final section of the book there are questions on the so-called rejection debate and on the possibility of replacing nuclear energy with other energy forms. (orig./HP) [de

    The present Dutch government compiled the title document to enable the future Dutch government to declare its opinion on the nuclear energy problemacy. The most important questions which occupy the Dutch society are discussed: safe application and risks of nuclear energy, radioactive wastes and other environmental aspects, and the possible danger of misusing nuclear technology. In chapter two attention is paid to the policy, as formulated by the Dutch government, with regard to risks of nuclear power plants. Next the technical safety regulations that have to be met are dealt with. A brief overview is given of the state of the art of commercially available nuclear reactors, as well as reactors under development. The nuclear waste problem is the subject of chapter three. Attention is paid to the Dutch policy that has been formulated and is executed, the OPLA-program, in which the underground storage of radioactive wastes is studied, the research on the conversion of long-lived radioactive isotopes to short-lived radioactive isotopes, and planned research programs. In chapter four, other environmental effects of the use of nuclear power are taken into consideration, focusing on the nuclear fuel cycle. International obligations and agreements to guarantee the peaceful use of nuclear energy (non-proliferation) are mentioned and discussed in chapter four. In chapter six the necessity to carry out surveys to determine public support for the use of nuclear energy is outlined. In the appendices nuclear energy reports in the period 1986-present are listed. Also the subject of uranium supplies is discussed and a brief overview of the use of nuclear energy in several other countries is given. 2 tabs., 5 annexes, 63 refs

    Our choice of energy sources has important consequences for the economy and the environment. Nuclear energy is a controversial energy source, subject to much public debate. Most individuals find it difficult to decide between conflicting claims and allegations in a variety of technical subjects. Under these circumstances, knowledge of various relevant inquiries can be helpful. This publication summarizes the composition and major findings of more than thirty nuclear energy inquiries. Most of the these are Canadian, but others are included where they have relevance. The survey shows that, contrary to some claims, virtually every aspect of nuclear energy has been subject to detailed scrutiny. The inquiries' reports include many recommendations on how nuclear energy can be exploited safely, but none rejects it as an acceptable energy source when needed. (Author) 38 refs

    Full Text Available Sustainable energy development implies the need for the emerging potential energy sources which are not producing adverse effect to the environment. In this respect nuclear energy has gained the complimentary favor to be considered as the potential energy source without degradation of the environment. The sustainability evaluation of the nuclear energy systems has required the special attention to the criteria for the assessment of nuclear energy system before we can make firm justification of the sustainability of nuclear energy systems. In order to demonstrate the sustainability assessment of nuclear energy system this exercise has been devoted to the potential options of nuclear energy development, namely: short term option, medium term option, long term option and classical thermal system option. Criteria with following indicators are introduced in this analysis: nuclear indicator, economic indicator, environment indicator, social indicator... The Sustainability Index is used as the merit for the priority assessment among options under consideration.

    A description is given of the damaged caused to various structures, buildings, houses, mechanical equipment and electrical equipment by underground nuclear explosions in granite. For each type of equipment or building are given the limiting distances for a given degree of damage. These distances have been related to a parameter characterizing the movement of the medium; it is thus possible to generalize the results obtained in granite, for different media. The problem of estimating the damage caused at a greater distance from the explosion is considered.

  4. Is nuclear energy ethically justifiable?

    International Nuclear Information System (INIS)

    Zuend, H.

    1987-01-01

    Nuclear technology offers the chance to make an extremely long term contribution to the energy supply of the earth. The use of nuclear energy is ethically justifiable, provided that several fundamental rules are obeyed during the technical design of nuclear installations. Such fundamental rules were unequivocally violated in the nuclear power plant Chernobyl. They are, however, fulfilled in the existing Swiss nuclear power plants. Improvements are possible in new nuclear power plants. Compared to other usable energy systems nuclear energy is second only to natural gas in minimal risk per generated energy unit. The question of ethical justification also may rightly be asked of the non-use of nuclear energy. The socially weakest members of the Swiss population would suffer most under a renunciation of nuclear energy. Future prospects for the developing countries would deteriorate considerably with a renunciation by industrial nations of nuclear energy. The widely spread fear concerning the nuclear energy in the population is a consequence of non-objective discussion. 8 refs., 2 figs

    Carlos Villota. Director of Nuclear Energy of UNESA gave an overview of the Spanish nuclear industry, the utility companies and the relevant institutions. Companies of the nuclear industry include firms that produce heavy components or equipment (ENSA), manufacturers of nuclear fuel (ENUSA), engineering companies, the National Company for Radioactive Waste Management (ENRESA), and nuclear power plants (nine units at seven sites). Nuclear energy is a significant component of the energy mix in Spain: 11% of all energy produced in Spain is of nuclear origin, whilst the share of nuclear energy in the total electricity generation is approximately 23%. The five main players of the energy sector that provide for the vast majority of electricity production, distribution, and supply have formed the Spanish Electricity Industry Association (UNESA). The latter carries out co-ordination, representation, management and promotion tasks for its members, as well as the protection of their business and professional interests. In the nuclear field, UNESA through its Nuclear Energy Committee co-ordinates aspects related to nuclear safety and radiological protection, regulation, NPP operation and R and D. Regarding the institutional framework of the nuclear industry, ENSA, ENUSA and ENRESA are controlled by the national government through the Ministry of Economy and Finance and the Ministry of Science and Technology. All companies of the nuclear industry are licensed by the Ministry of Industry, Tourism and Trade (MITYC), while the regulatory body is the Nuclear Safety Council (CSN). It is noteworthy that CSN is independent of the government, as it reports directly to Parliament. (author)

  10. Nuclear Energy General Objectives

    International Nuclear Information System (INIS)

    2011-01-01

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world'. One way it achieves this objective is to issue publications in various series. Two of these series are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III, paragraph A.6, of the IAEA Statute, the IAEA safety standards establish 'standards of safety for protection of health and minimization of danger to life and property.' The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are primarily written in a regulatory style, and are binding on the IAEA for its own activities. The principal users are Member State regulatory bodies and other national authorities. The IAEA Nuclear Energy Series consists of reports designed to encourage and assist research on, and development and practical application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia and politicians, among others. The information is presented in guides, reports on the status of technology and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The series complements the IAEA's safety standards, and provides detailed guidance, experience, good practices and examples on the five areas covered in the IAEA Nuclear Energy Series. The Nuclear Energy Basic Principles is the highest level publication in the IAEA Nuclear Energy Series and describes the rationale and vision for the peaceful uses of nuclear energy. It presents eight Basic Principles on which nuclear energy systems should be based to fulfil nuclear energy's potential to help meet growing global energy needs. The Nuclear Energy Series Objectives are the second level publications. They describe what needs to be

    The rapid development of nuclear energy demands an urgent solution to the health problems arising from the discharge into the environment of radioactive residues produced by nuclear installations. - To be able to evaluate the risks run by the population and to fix tolerance limits for waste discharge, it is necessary to possess an exact knowledge of the course taken by the radioelements discharged, from their source until they reach man. The incorporation of radioelements in food cycles is the first risk to take into consideration. The factors involved in all stages of this transmission must be foreseen, whether they concern physical or biological media, because of their continuity and their interdependence. Finally, socio-economic and dietetic data must be collected in order that the risks and tolerance levels estimated are based on concrete and experimental rather than theoretical knowledge. The risk of nuclear accidents in the atomic industry, although very improbable, must be taken into consideration because of the seriousness of their consequences. The health problems arise in the field of professional hygiene on the one hand and in that of public hygiene on the other. In the first field the risk is two-fold and involves irradiation and contamination. The public sphere is reduced essentially to the risk of contamination by radioactive substances accidentally released in the surrounding medium. The health studies to be conducted in this field therefore include research not only on irradiation or contamination therapeutics but also on the transfer of radioelements from the accident site to man, mainly through food cycles, in their physical and in their biological components. Studies of this kind form the basis of decisions in the health field which would have to be taken in the case of an accident.

  14. Soft energy vs nuclear energy

    International Nuclear Information System (INIS)

    Ando, Yoshio

    1981-01-01

    During the early 1960s, a plentiful, inexpensive supply of petroleum enabled Japanese industry to progress rapidly; however, almost all of this petroleum was imported. Even after the first oil crisis of 1973, the recent annual energy consumption of Japan is calculated to be about 360 million tons in terms of petroleum, and actual petroleum forms 73% of total energy. It is necessary for Japan to reduce reliance on petroleum and to diversify energy resources. The use of other fossil fuels, such as coal, LNG and LPG, and hydraulic energy, is considered as an established alternative. In this presentation, the author deals with new energy, namely soft energy and nuclear energy, and discusses their characteristics and problems. The following kinds of energy are dealt with: a) Solar energy, b) Geothermal energy, c) Ocean energy (tidal, thermal, wave), d) Wind energy, e) Biomass energy, f) Hydrogen, g) Nuclear (thermal, fast, fusion). To solve the energy problem in future, assiduous efforts should be made to develop new energy systems. Among them, the most promising alternative energy is nuclear energy, and various kinds of thermal reactor systems have been developed for practical application. As a solution to the long-term future energy problem, research on and development of fast breeder reactors and fusion reactors are going on. (author)

    Speaking from the platform of the XIIIth annual session of the International Atomic Energy Agency, at New Delhi, AEC managing director Michel Pecqueur made a solemn appeal to the world community for the decisions which are needed on energy. The present energy crisis can lead the world to a recession and be a factor in grave troubles for peace and balance in the world. The crisis cannot be resolved without accrued recourse to the use of nuclear energy. Two essential themes were outlined: the development of nuclear energy in the world, and the increased reduction of proliferation risks. In concluding, he expressed the hop that with a greater effort in information media, the nuclear fact-of-life would be better accepted by the general public in future, for it is there that lies a brake which may hinder nuclear energy development [fr

    Nuclear energy has a strong relation to a society. However, due to accidents and scandals having occurred in recent years, people's reliability to nuclear energy has significantly swayed and is becoming existence of a worry. Analyzing such a situation and grasping the problem contained are serious problems for people engaging in nuclear field. In order that nuclear energy is properly used in society, communication with general public and in nuclear power plant site area are increasingly getting important as well as grasping the situation and surveying measures for overcoming the problems. On the basis of such an analysis, various activities for betterment of public acceptance of nuclear energy by nuclear industry workers, researchers and the government are proposed. (J.P.N.)

    The terms radioactivity and nuclear energy, which have become words causing irritation in the political sphere, actually represent nothing but a large potential for innovative exploitation of natural resources. The contributions to this publication of the Karlsruhe Research Center examine more closely three major aspects of radioactivity and nuclear energy. The first paper highlights steps in the history of the discovery of radioactivity in the natural environment and presents the state of the art in health physics and research into the effects of exposure of the population to natural or artificial radionuclides. Following contributions focus on: Radiochemical methods applied in the medical sciences (diagnostic methods and devices, therapy). Nuclear energy and electricity generation, and the related safety policies, are an important subject. In this context, the approaches and pathways taken in the field of nuclear science and technology are reported and discussed from the angle of nuclear safety science, and current trends are shown in the elaboration of advanced safety standards relating to nuclear power plant operation and ultimate disposal of radioactive wastes. Finally, beneficial aspects of nuclear energy in the context of a sustainable energy policy are emphasized. In particular, the credentials of nuclear energy in the process of building an energy economy based on a balanced energy mix which combines economic and ecologic advantages are shown. (orig./CB) [de

  5. Nuclear energy and jobs

    International Nuclear Information System (INIS)

    Goldfinger, N.

    1976-01-01

    Mr. Goldfinger, Research Director of AFL-CIO, examines the problem of energy in general, nuclear in particular, and the employment relationship. The energy shortages in the U.S. and its dependence on oil are cited. Directly connected with this serious problem relating to energy are jobs, income, and living standards. If energy is not available, industries will be unable to expand to meet the needs of the growing population; and prices of goods will rise. From an evaluation of what experts have said, Mr. Goldfinger concludes that increased coal production and better coal technology cannot meet energy demands; so the sharp increase both in volume and as a percentage of total energy needed in the future will have to come from nuclear power. Development of alternative sources is necessary, he feels, and intense research on these is needed now. The employment impact in the nuclear energy scenario is analyzed according to the trades involved. It is estimated that 1.5 million jobs in the nuclear industry would be open by the year 2000 if nuclear is to provide one-fourth of energy supplies. The employment picture, assuming abandonment of nuclear energy, is then discussed

    The data presented in the different chapters lead to show that nuclear energy ids not a sustainable energy sources for the following reasons: investments in nuclear energy account financing that lacks to energy efficiency programmes. The nuclear programmes have negative effects such the need of great electric network, the need of highly qualified personnel, the freezing of innovation in the fields of supply and demand, development of small performing units. The countries resort to nuclear energy are among the biggest carbon dioxide emitters, because big size nuclear power plants lead to stimulate electric power consumption instead of inducing its rational use. Nuclear energy produces only electric power then a part of needs concerns heat (or cold) and when it is taken into account nuclear energy loses its advantages to the profit of cogeneration installations. Finally nuclear energy is a dangerous energy source, difficult to control as the accident occurring at Tokai MURA showed it in 1998. The problem of radioactive wastes is not still solved and the nuclear proliferation constitutes one of the most important threat at the international level. (N.C.)

    The rapid development of nuclear energy demands an urgent solution to the health problems arising from the discharge into the environment of radioactive residues produced by nuclear installations. - To be able to evaluate the risks run by the population and to fix tolerance limits for waste discharge, it is necessary to possess an exact knowledge of the course taken by the radioelements discharged, from their source until they reach man. The incorporation of radioelements in food cycles is the first risk to take into consideration. The factors involved in all stages of this transmission must be foreseen, whether they concern physical or biological media, because of their continuity and their interdependence. Finally, socio-economic and dietetic data must be collected in order that the risks and tolerance levels estimated are based on concrete and experimental rather than theoretical knowledge. The risk of nuclear accidents in the atomic industry, although very improbable, must be taken into consideration because of the seriousness of their consequences. The health problems arise in the field of professional hygiene on the one hand and in that of public hygiene on the other. In the first field the risk is two-fold and involves irradiation and contamination. The public sphere is reduced essentially to the risk of contamination by radioactive substances accidentally released in the surrounding medium. The health studies to be conducted in this field therefore include research not only on irradiation or contamination therapeutics but also on the transfer of radioelements from the accident site to man, mainly through food cycles, in their physical and in their biological components. Studies of this kind form the basis of decisions in the health field which would have to be taken in the case of an accident.

    2007-01-01

    According to the 'framework for nuclear energy policy' (October, 2005 adopted by cabinet), basic goals of nuclear policy are (1) for nuclear energy to continue to meet more than around 30-40% of electricity supply, and also (2) to further promote a fuel cycle steadily aiming at commercial introduction of a fast breeder by 2050. In order to realize an aim of this framework for nuclear energy policy', the nuclear energy subcommittee of the METI advisory committee deliberated concrete actions and the subcommittee recommendations were drawn up as 'Japan's nuclear energy national plan' in August, 2006 and incorporated as main part of the revised 'basic plan on energy' adopted by the cabinet in March 2007. Backgrounds and directions of future actions for nuclear energy policy were described. (T. Tanaka)

  17. Nuclear energy outlook 2008

    2008-01-01

    With the launch today of its first Nuclear Energy Outlook, the OECD Nuclear Energy Agency (NEA) makes an important contribution to ongoing discussions of nuclear energy's potential role in the energy mixes of its member countries. As world energy demand continues to grow unabated, many countries face serious concerns about the security of energy supplies, rising energy prices and climate change stemming from fossil fuel consumption. In his presentation, the NEA Director-General Luis Echavarri is emphasizing the role that nuclear power could play in delivering cost-competitive and stable supplies of energy, while also helping to reduce greenhouse gas emissions. In one Outlook scenario, existing nuclear power technologies could provide almost four times the current supply of nuclear-generated electricity by 2050. Under this scenario, 1400 reactors of the size commonly in use today would be in operation by 2050. But in order to accomplish such an expansion, securing political and societal support for the choice of nuclear energy is vital. An ongoing relationship between policy makers, the nuclear industry and society to develop knowledge building and public involvement will become increasingly important, the publication notes. Moreover, governments have a clear responsibility to maintain continued effective safety regulation, advance efforts to develop radioactive waste disposal solutions and uphold and reinforce the international non-proliferation regime. The authors find that the security of energy from nuclear power is more reliable than that for oil or gas. Additionally, uranium's high energy density means that transport is less vulnerable to disruption, and storing a large energy reserve is easier than for fossil fuels. One tonne of uranium produces the same energy as 10 000 to 16 000 tonnes of oil using current technology. Ongoing technological developments are likely to improve that performance even more. Until the middle of the century the dominant reactor

    Highlights: • The paper deals with the use of (U)RANS and LES in nuclear engineering applications. • It gives some ideas and guidelines to run high quality computations. • Some perspectives are drawn concerning the development of (U)RANS and LES approaches in the future. - Abstract: The present paper gives some ideas and guidelines in order to run high quality (U)RANS or LES computations. The paper starts with (U)RANS approaches, advocating the use of Reynolds Stress Models for complex flows and recommending further work on modeling of turbulent heat fluxes, which remains today too basic in industry. The superiority of wall-resolved models vs. wall-modeled in RANS is recalled and the use of adaptive wall treatment is suggested. The concept of Unsteady RANS is finally questioned. Then, important issues around LES are raised. The mesh refinement criteria are recalled for wall-resolved LES and the use of wall models addressed. The production of DNS and wall-resolved LES calculations for flow understanding and RANS validation is encouraged.

    This summary represents an overview of the energy situation in Armenia and, in particular, the nuclear energy development during the last period of time. the energy sector of Armenia is one of the most developed economy branches of the country. The main sources of energy are oil products, natural gas, nuclear energy, hydropower, and coal. In the period of 1985-1988 the consumption of these energy resources varied between 12-13 million tons per year of oil equivalent. Imported energy sources accounted for 96% of the consumption. During the period 1993-1995 the consumption dropped to 3 million tons per year. Electricity in Armenia is produced by three thermal, one nuclear, and two major hydroelectric cascades together with a number small hydro units. The total installed capacity is 3558 MW. Nuclear energy in Armenia began its development during the late 1960's. Since the republic was not rich in natural reserves of primary energy sources and the only domestic source of energy was hydro resource, it was decided to build a nuclear power plant in Armenia. The Armenian Nuclear Power Plant (ANPP) Unit 1 was commissioned in 1996 and Unit 2 in 1980. The design of the ANPP was developed in 1968-1969 and was based on the project of Units 3 and 4 of the Novovoronezh NPP. Both units of the plant are equipped with reactors WWER-440 (V -270) type, which are also in use in some power stations in Russian Federation, Bulgaria, and Slovakia. Currently in Armenia, 36% of the total electricity production is nuclear power electricity. (authors)

    2007-12-01

    Developing nuclear energy that is sustainable, safe, has little waste by-product, and cannot be proliferated is an extremely vital and pressing issue. To resolve the four issues through free thinking and overall vision, research activities of 'innovative nuclear energy systems' and 'innovative separation and transmutation' started as a unique 21st Century COE Program for nuclear energy called the Innovative Nuclear Energy Systems for Sustainable Development of the World, COE-INES. 'Innovative nuclear energy systems' include research on CANDLE burn-up reactors, lead-cooled fast reactors and using nuclear energy in heat energy. 'Innovative separation and transmutation' include research on using chemical microchips to efficiently separate TRU waste to MA, burning or destroying waste products, or transmuting plutonium and other nuclear materials. Research on 'nuclear technology and society' and 'education' was also added in order for nuclear energy to be accepted into society. COE-INES was a five-year program ending in 2007. But some activities should be continued and this roadmap detailed them as a rough guide focusing inventions and discoveries. This technology roadmap was created for social acceptance and should be flexible to respond to changing times and conditions. (T. Tanaka)

    2017-05-01

    Complex and exotic nuclear geometries, collectively referred to as "nuclear pasta," are expected to appear naturally in dense nuclear matter found in the crusts of neutron stars and supernovae environments. The pasta geometries depend on the average baryon density, proton fraction, and temperature and are critically important in the determination of many transport properties of matter in supernovae and the crusts of neutron stars. Using a set of self-consistent microscopic nuclear energy density functionals, we present the first results of large scale quantum simulations of pasta phases at baryon densities 0.03 ≤ρ ≤0.10 fm-3 , proton fractions 0.05 ≤Yp≤0.40 , and zero temperature. The full quantum simulations, in particular, allow us to thoroughly investigate the role and impact of the nuclear symmetry energy on pasta configurations. We use the Sky3D code that solves the Skyrme Hartree-Fock equations on a three-dimensional Cartesian grid. For the nuclear interaction we use the state-of-the-art UNEDF1 parametrization, which was introduced to study largely deformed nuclei, hence is suitable for studies of the nuclear pasta. Density dependence of the nuclear symmetry energy is simulated by tuning two purely isovector observables that are insensitive to the current available experimental data. We find that a minimum total number of nucleons A =2000 is necessary to prevent the results from containing spurious shell effects and to minimize finite size effects. We find that a variety of nuclear pasta geometries are present in the neutron star crust, and the result strongly depends on the nuclear symmetry energy. The impact of the nuclear symmetry energy is less pronounced as the proton fractions increase. Quantum nuclear pasta calculations at T =0 MeV are shown to get easily trapped in metastable states, and possible remedies to avoid metastable solutions are discussed.

    France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

    Australian authorities have been traditionally opposed to nuclear energy. The interdiction to build nuclear power plants in the Australian states without the approval of the federal authority was even officially written in the environment code in 1999. Today coal provides 75% of the electricity needs of Australia. Because of climate warming, things are changing, the Australian government is now considering the possibility of using nuclear energy and a site located in southern Australian has been selected for the disposal of low and intermediate level radioactive wastes. In this context the Australian Nuclear Association (ANA) is developing an ambitious program for the promotion of all the applications of nuclear energy through the organisation of conferences and meetings with various experts of nuclear industry. The aim is to make the public aware of the assets of nuclear energy. (A.C.)

    Nuclear Energy Data is the Nuclear Energy Agency's annual compilation of statistics and country reports documenting nuclear power status in NEA member countries and in the OECD area. Information provided by governments includes statistics on total electricity produced by all sources and by nuclear power, fuel cycle capacities and requirements, and projections to 2035, where available. Country reports summarise energy policies, updates of the status in nuclear energy programs and fuel cycle developments. In 2016, nuclear power continued to supply significant amounts of low-carbon baseload electricity, despite strong competition from low-cost fossil fuels and subsidised renewable energy sources. Three new units were connected to the grid in 2016, in Korea, Russia and the United States. In Japan, an additional three reactors returned to operation in 2016, bringing the total to five under the new regulatory regime. Three reactors were officially shut down in 2016 - one in Japan, one in Russia and one in the United States. Governments committed to having nuclear power in the energy mix advanced plans for developing or increasing nuclear generating capacity, with the preparation of new build projects making progress in Finland, Hungary, Turkey and the United Kingdom.

This is also a sensitive topic among the opponents and proponents of the nuclear energy in Turkey. Nuclear energy is very important since it provides about 17 % of the electric energy in the world and is used in industry and medical area. However, Turkey has not declared any policy about this yet, because of the worries about the environmental reasons and has not gained any progress about nuclear energy. First of all, Turkey must use her geothermal, hydropower, hard coal, solar and wind energies. Otherwise, Turkey may find herself in a competition with her neighboring countries

    The wide use of nuclear energy has promoted the development of China's economy and the improvement of people's living standards. To some extent, the exploitation of nuclear power plants will solve the energy crisis faced with human society. Before the utilization of nuclear fusion energy, nuclear fission energy will be greatly needed for the purpose of alleviating energy crisis for a long period of time. Compared with fossil fuel, on the one hand, nuclear fission energy is more cost-efficient and cleaner, but on the other hand it will bring about many problems hard to deal with, such as the reprocessing and disposal of nuclear spent fuel, the contradiction between nuclear deficiency and nuclear development. This paper will illustrate the future and prospect of nuclear energy from the perspective of the difficulty of nuclear development, the present reprocessing way of spent fuel, and the measures taken to ensure the sustainable development of nuclear energy. By the means of data quoting and comparison, the feasibility of sustainable development of nuclear energy will be analyzed and the conclusion that as long as the nuclear fuel cycling system is established the sustainable development of nuclear energy could be a reality will be drawn.

    The main concern of Pugwash, with very good reason, is nuclear disarmament, but a negative attitude towards nuclear energy is not only futile, but counterproductive as it misses opportunities to appropriately influence its development. Since nuclear energy cannot be abandoned for ecological (decrease in greenhouse gases emission) and economic reasons as a long term energy source, then efforts should be devoted to make it safe from proliferation, which is possible from scientific and technological point of view

    Fossil fuels such as coal oil, and gas, massively pollute the Earth atmosphere (CO, CO 2 , SOX, NOX...), provoking acid rains and changing the global climate by increasing the greenhouse effect, while nuclear energy does not participate in these pollutions and presents well-founded environmental benefits. Renewable energies (solar, wind) not being able to deliver the amount of energy required by populations in developing and developed countries, nuclear energy is in fact the only clean and safe energy available to protect the planet during the 21 century. The first half of the book, titled The Atomic Paradox, describes in layman language the risks of nuclear power, its environmental impact, quality and safety standards, waste management, why a power reactor is not a bomb, energy alternatives, nuclear weapons, and other major global and environmental problems. In each case the major conclusions are framed for greater emphasis. Although examples are taken from the French nuclear power program, the conclusions are equally valid elsewhere. The second half of the book is titled Information on Nuclear Energy and the Environment and briefly provides a historical survey, an explanation of the different types of radiation, radioactivity, dose effects of radiation, Chernobyl, medical uses of radiation, accident precautions, as well as a glossary of terms and abbreviations and a bibliography.

    Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants remained steady in 2013 despite the progressive shutdown of all reactors in Japan leading up to September and the permanent closure of six reactors in the OECD area. Governments committed to maintaining nuclear power in the energy mix advanced plans for increasing nuclear generating capacity, and progress was made in the development of deep geological repositories for spent nuclear fuel, with Finland expected to have the first such facility in operation in the early 2020's. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'StatLinks'.

    We have not been able to obtain closure in the nuclear energy debate because the public perception of nuclear energy is out of sync with reality. The industry has not been about to deal with the concerns of those opposed to nuclear energy because its reaction has been to generate and disseminate more facts rather than dealing with the serious moral and ethical questions that are being asked. Nuclear proponents and opponents appeal to different moral communities, and those outside each community cannot concede that the other might be right. The Interfaith Program for Public Awareness of Nuclear Issues (IPPANI) has been formed, sponsored by members of the Jewish, Baha'i, Roman Catholic, United, and Anglican faiths, to provide for a balanced discussion of the ethical aspects of energy.

    1996-01-01

    Japan has scant energy resources, and more than 80% of its energy demand depends on other countries. The energy problem should be considered not only from the domestic viewpoint of energy supply and demand but also from the global viewpoint. Japanese nuclear power generation accounts for about 30% of its total electric power. The main strategy of Japan is to secure stable energy supply through the establishment of nuclear fuel cycle, and to efficiently use the plutonium and residual uranium recovered from spent nuclear fuel. The sodium leakage from the prototype FBR 'Monju' in December, 1995 raised the anxiety about the nuclear policy. People living in Japan should be assured the peace of mind about the development and utilization of nuclear energy. Regarding coexistence of nuclear energy and people, stronger demand of clearer reflection of public opinion to nuclear policy, holding of the round table conferences on nuclear policy, various efforts toward the coexistence of nuclear energy and people and so on are discussed. The development and utilization of nuclear energy in Japan and overseas are reported on nuclear nonproliferation, safety assurance, information disclosure, present and future of nuclear power generation, international cooperation and others.

    Irie, Kazutomo; Kanda, Keiji

    2002-01-01

    This paper analyzes the view expressed by the Japanese government on the role of nuclear energy for energy security through scrutiny of Japan's policy documents. The analysis revealed that the contribution by nuclear energy to Japan's energy security has been defined in two ways. Nuclear energy improves short-term energy security with its characteristics such as political stability in exporting countries of uranium, easiness of stockpiling of nuclear fuels, stability in power generation cost, and reproduction of plutonium and other fissile material for use by reprocessing of spent fuel. Nuclear energy also contributes to medium- and long-term energy security through its characteristics that fissile material can be reproduced (multiplied in the case of breeder reactor) from spent fuels. Further contribution can be expected by nuclear fusion. Japan's energy security can be strengthened not only by expanding the share of nuclear energy in total energy supply, but also by improving nuclear energy's characteristics which are related to energy security. Policy measures to be considered for such improvement will include (a) policy dialogue with exporting countries of uranium, (b) government assistance to development of uranium mines, (c) nuclear fuel stockpiling, (d) reprocessing and recycling of spent fuels, (e) development of fast breeder reactor, and (f) research of nuclear fusion.

    China receives attention from the whole world as not only have they become a country spending the most energy in the world, but also the amount of energy they need is still increasing. Consequently, many problems related to environmental pollution have occurred in China. Recently, China agreed to reduce carbon emission in order to deal with this issue. Therefore, they need to find energy sources other than fossil fuel; the nuclear energy could be an alternative. In addition, it is considered to be a base load owing to its low fuel cost and continuation of electricity generation. In reality, the Chinese government is planning to build about 400 Nuclear Power Plants (NPPs) up to 2050. Therefore, it is expected that China will become a giant market in the nuclear industry. It could give us either chances to join the huge market or challenges to meet not merely nuclear fuel price crisis but competitors from China in the world nuclear power plant market. In any case, it is obvious that the energy policy of China would influence us significantly. Accordingly, we need appropriate prediction of the Chinese nuclear industry to cope with the challenges.

  11. Is nuclear energy ethically justifiable?

    International Nuclear Information System (INIS)

    Zuend, H.

    1988-01-01

    Nuclear technology brings the chance to provide an essential long term contribution to the energy supply of the world population and to use the raw materials uranium and thorium which have no other use. The use of nuclear energy is ethically justifiable providing certain simple fundamental rules for the design of nuclear facilities are observed. Such rules were clearly violated before the reactor accident at Chernobyl. They are, however, observed in our existing nuclear power plants. Compared with other energy systems nuclear energy has, with the exception of natural gas, the lowest risk. The consideration of the ethical justification of nuclear energy must also include the question of withdrawal. A withdrawal would have considerable social consequences for the industrial nations as well as for the developing countries. The problem of spreading alarm (and concern) by the opponents of nuclear energy should also be included in the ethical justification. 8 refs., 2 figs

    With 15% of the world's population and an economic growth rate that increases the aspiration of its people to better quality of life, India has a voracious appetite for energy. Nuclear power is one of the options of providing safe, environmentally benign, reliable and economically competitive energy services. Nuclear power world over provides about 16% of electricity through 440 nuclear power plants with a total installed capacity of 361.582 GW (as of January 2004, IAEA PRIS data). Nuclear energy has traditionally played a small role in meeting India's energy requirements. Nuclear power makes up only 4,120 MW, constituting 2.6%, of the total electricity generation capacity. India is a power hungry nation and needs to switch over from its tremendous dependence on fossil fuels to alternative sources of energy like solar energy, bio energy and nuclear energy. Indian nuclear power plants have progressively attained excellent operation performances. However, the changing economic and geopolitical situation in the energy sector has made it imperative to emphasize the significance of nuclear energy in the future energy landscape of the country. The present paper discuss the importance, demand and supply pattern of nuclear energy and its economics. (author)

    Higher knowledge has long been hypothesized as leading to better acceptance of nuclear energy, but in the last years other factors such as risk perception and trust in nuclear risk governance were also recognized as key elements. While stakeholder involvement is now fully recognized as a key element for nuclear energy acceptance, there are still questions about the impact of higher knowledge. This paper investigates the relation between knowledge about the nuclear domain, risk perception of nuclear risks, confidence in the management of nuclear technologies, on the one hand, and the attitude towards nuclear energy and opinion about nuclear energy, on the other hand. It also studies the factors that are pleading in favour or against nuclear energy and their relation with the forementioned variables. The study is based on empirical data from a large scale opinion survey in Belgium between 25/05/2011 and 24/06/2011, i.e. the third month after the accident in Fukushima. The sample consisted of 1020 respondents and is representative for the Belgian adult population (18+) with respect to gender, age, region, province, habitat and social class. Our results show that confidence in the safe management of nuclear technologies as well as the perceived strength of the arguments pro/against nuclear are driving factors for people's attitude towards nuclear energy. Higher confidence and stronger adherence to the arguments in favour of nuclear energy lead to higher acceptance. The correlation between knowledge and attitude/opinion towards nuclear energy is statistically significant, but rather low, showing only a weak effect of knowledge on attitudes or opinions about nuclear energy. A weak effect is also observed for risk perception of nuclear risks, lower risk perception leading to a somewhat more positive attitude/opinion about nuclear energy. In the study we also highlight that the main factors seen as pleading in favour or against nuclear energy are the same, both for

    The total electricity generated in 1998 was 215,300 GWh with 43,261 MWe of total installed capacity of electric power, while in 1978 when the first Nuclear Power Plant began operation it was 31,510 GWh with 6,916 MWe installed capacity. The share of nuclear power generation in 1998 increased up to 41.7%. Currently, 16 units of nuclear power are operating with an additional four units under construction. Nuclear power has contributed to enhancing energy security and supplying stable energy for Korea. The government's strong commitment to the nuclear power program together with a long-term national policy resulted in favorable conditions for KEPCO to manage the program and promote increasing levels of national participation in successive nuclear power projects. The role of nuclear power as a sustainable energy resource can not be emphasized enough with respect to global environmental issues. Increasing the share of nuclear power in the total installed capacity for electricity generation will undoubtedly play a very important role. (author)

    2 1/2 years ago a consultation group was formed to help the Section for Social Questions of the Council of Churches in the Netherlands, to answer questions in the area of nuclear energy. During this time the character of the questions has changed considerably. In the beginning people spoke of fear and anxiety over the plans for the application of this new technical development but later this fear and anxiety turned to protest and opposition. This brochure has been produced to enlighten people and try and answer their alarm, by exploring the many facets of the problems. Some of these problems are already being deeply discussed by the public, others play no role in the forming of public opinion. The points of view of the churches over nuclear energy are not expressed, the brochure endeavours to express that nuclear energy problems are a concern for the churches. Technical and economic information and the most important social questions are discussed. (C.F.)

    The world nuclear energy is on the upswing. This is shown by lifetime extensions up to 60 years and the construction of new nuclear power plants. Especially, the progressive climate change requires new, definitive, fast and decisive solutions. Europe has to find the right energy mix for the future having the magic triangle of environmental sustainability, security of supply and economic affordability in mind. At the centre of all the efforts made by many countries all over the world, nuclear is one vital key technology to face and combat global warming. Nuclear has a positive eco-balance, nuclear gives security of supply and nuclear power generation is competitive. Beside this the most important fact is and will be the high safety to run a nuclear power plant. The energy mix in the EU of the next decades will be defined today. It is vital to consider every option, which can contribute to a sustainable energy mix. Nuclear alone is not the solution for all problems but there will be no sustainable solution without nuclear.

    Nuclear energy in Thailand can be highlighted when the Office of Atomic Energy for Peace (OAEP) was established since 1961 for taking role of nuclear safety regulation, conducting research and promotion for peaceful uses of nuclear energy. Its main facilities were the 1 megawatt Thai Research Reactor-1 (TRR-1) and the Cobalt-60 Gamma Irradiator. Since then there have been substantial progress made on utilization of nuclear energy in various institutions and in private sectors. Nowaday, there are around 500 units of nuclear energy users in Thailand, i.e. 100 units in medicine, 150 units in education and 250 units in industry. In terms of nuclear power for electricity generation, the Electricity Generating Authority of Thailand (EGAT) has conducted the activities to support the nuclear power plant project since 1972 however, because there is widespread public concerned about nuclear safety, waste disposal and recently economic problems in Thailand, nuclear energy option is not put in immediate plan for alternative energy resource. Within the short future, increased in economical, demand fir electricity and safe operation of nuclear plants will likely be demonstrated and recognized. Nuclear energy should remain as an option in the long-term energy strategies for Thailand. (author)

    This book originated in the training courses for teachers of grammar- and secondary schools in Dillingen (Bavaria). The aim of these courses is to become informed about the latest state in one field of physics. The lectures are well-known experts in the respective fields. In the latest study (1980) of the National Academy of Sciences the experts came to the conclusion that without further development nuclear power plants the utilization of too much coal would become necessary and involve irreversible environmental damage (see chapter 6). There are two important obstacles impeding the further extension of nuclear energy. The first problem to be solved is the processing and storage of radioactive waste. This is a more technical task and can be treated in a satisfactory way. The second obstacle is less easy to take as the population has to be convinced that a nuclear power plant can be operated with almost unbelievable safety (see chapter 5) and be shut down safely in the case of incidents. The most promising possibility of controlled nuclear fusion as energy source is still many decades- if feasible at all- away from being performed (see chapter. 7). In the Soviet Union 25% of the electric energy production shall be proceed from nuclear power plants by the year 1990. (orig./GL) [de

    The energy problem poses a big challenge to a developing country like the Philippines. The development of renewable energy sources is not enough. Aware then of the limitations of these energy sources, in spite of arguments against nuclear energy we have no other recourse but to go nuclear. This symposium emphasizes the importance of energy development to attain the country's progress and discusses the pros and economics of nuclear power. (RTD)

    In Belgium, approximately 60 percent of the produced electricity is generated by nuclear power. At present, nuclear power production tends to stagnate in Europe and North America but is still growing in Asia. The document gives an overview of the present status and the future energy demand with emphasis on electric power. Different evaluation criteria including factors hindering and factors promoting the expansion of nuclear power as well as requirements of new nuclear power plants are discussed. The extension of the lifetime of existing facilities as well as fuel supply are taken into consideration. A comparative assesment of nuclear power with other energy sources is made. The report concludes with estimating the contribution and the role of nuclear power in future energy demand as well as with an overview of future reactors and research and development programmes

    Nuclear energy is controversial. But what's all about really in the controversy? It's about more than safty or electricity prices. Nuclear energy is not only a technical or political question, but also a moral, a human. The discussion enter various rational and irrational arguments, beside straightforward arguments various misleading and mendacious exist. The present publication is comprehensively dedicated to the thema of nuclear energy - its pro and contra - and considers its risks and advantages. Thereby the sources of energy, the processes in the nuclear reactor, and the risk potentials (Harrisburg, Chernobyl, Fukushima) are illustratively and reproducibly presented. Extensively the text explains the forms of the radiation, its doses, and the tolerance of it. Also to the theme waste and final disposal an explaining chapter is dedicated and the question for the exit from nuclear energy elucidated. Finally the author appoints with the question ''How considers mankind nuclear energy world-wide'' the international comparison.

    This report presents facts and figures on new nuclear energy in the Netherlands, in the period after 2020. The information is meant to support a stakeholder discussion process on the role of new nuclear power in the transition to a sustainable energy supply for the Netherlands. The report covers a number of issues relevant to the subject. Facts and figures on the following issues are presented: Nuclear power and the power market (including impact of nuclear power on electricity market prices); Economic aspects (including costs of nuclear power and external costs and benefits, impact on end user electricity prices); The role of nuclear power with respect to security of supply; Sustainability aspects, including environmental aspects; The impact of nuclear power in three 'nuclear energy scenarios' for the Netherlands, within the context of a Northwest European energy market. The scenarios are: (1a) No new nuclear power in the Netherlands ('Base case'); (1b) After closure of the existing Borssele nuclear power plant by the end of 2033, the construction of new nuclear power plant that will operate in 2040. That plant is assumed to be designed not to have a serious core melt down accident (e.g. PBMR) (200 to 500 MWe); (2) New nuclear power shortly after closure the Borssele nuclear power plant in 2033 (1000 to 1600 MWe, 3rd Generation); (3) New nuclear power plants shortly after 2020 (2000 to 5000 MWe, 3rd Generation). Two electricity demand scenario background scenario variants have been constructed based on an average GDP growth of about 2% per year up to 2040. The first variant is based on a steadily growing electricity demand and on currently established NL and EU policies and instruments. It is expected to be largely consistent with a new and forthcoming reference projection 'Energy and Emissions 2010-2020' for the Netherlands (published by ECN and PBL in 2010). A lower demand variant is based on additional energy savings and on higher shares of renewable

  5. Political aspects of nuclear energy

    International Nuclear Information System (INIS)

    Kiener, E.

    1989-01-01

    In Switzerland as in other countries public opinion on nuclear energy has drastically changed with time. Surveys show that a majority at present favours abandoning nuclear energy in Switzerland, but does not consider feasible an immediate switchover to other forms of energy. The behaviour is contradictory because increasingly more electric power is used, even after Chernobyl. The resistence has many facets. The debate is largely focused on the question of future technological and economic development. Nuclear energy also became the scapegoat for a development of the last few decades it has not been responsible for (destruction of the environment, waste of natural resources). For the sake of the environment and future economic development, the continued use of nuclear energy has to be ensured. This calls for great efforts in order to convince the people that nuclear power is an essential and logical part of our energy supply. In this process, the fear of a nuclear energy and the unease about industrial society must not be dismissed as irrelevant. (orig.)

  10. Future of nuclear energy research

    International Nuclear Information System (INIS)

    Fuketa, Toyojiro

    1989-09-01

    In spite of the easing of worldwide energy supply and demand situation in these years, we believe that research efforts towards the next generation nuclear energy are indispensably necessary. Firstly, the nuclear colleagues believe that nuclear energy is the best major energy source from many points of view including the global environmental viewpoint. Secondly, in the medium- and long-range view, there will once again be a high possibility of a tight supply and demand situation for oil. Thirdly, nuclear energy is the key energy source to overcome the vulnerability of the energy supply structure in industrialized countries like Japan where virtually no fossil energy source exists. In this situation, nuclear energy is a sort of quasi-domestic energy as a technology-intensive energy. Fourthly, the intensive efforts to develop the nuclear technology in the next generation will give rise to a further evolution in science and technology in the future. A few examples of medium- and long-range goals of the nuclear energy research are development of new types of reactors which can meet various needs of energy more flexibly and reliably than the existing reactors, fundamental and ultimate solution of the radioactive waste problems, creation and development of new types of energy production systems which are to come beyond the fusion, new development in the biological risk assessment of the radiation effects and so on. In order to accomplish those goals it is quite important to introduce innovations in such underlying technologies as materials control in more microscopic manners, photon and particle beam techniques, accelerator engineering, artificial intelligence, and so on. 32 refs, 2 figs

  11. Nuclear energy and international cooperation

    International Nuclear Information System (INIS)

    Oshima, Keiichi

    1981-01-01

    There is no need to emphasize that nuclear energy cannot be developed without international cooperation at either the industrial or the academic level. In the meanwhile, there have been some marked political, economic and social changes in recent years which are posing constraints to the international cooperation in nuclear energy. The problems and constraints impeding nuclear power programs cannot be overcome by only one nation; international cooperation with common efforts to solve the problems is essential. Nuclear energy is different from fossil energy resources in that it is highly technology-intensive while others are resource-intensive. International cooperation in technology has an entirely different importance in the field of nuclear energy. Educational institutions will play a role in a new era of the international cooperation. (Mori, K.)

    2000-01-01

    Public perception on nuclear energy is much influenced by subjective impressions mostly formed through sensational and dramatic news of mass media or anti-nuclear groups. However, nuclear experts, those who have more relevant knowledge and information about nuclear energy, may have reasonable opinion based on scientific facts or inferences. Thus their opinion and consensus should be examined and taken into account during the process of nuclear energy policy formulation. For the purpose of eliciting experts' opinion, the web-based on-line survey system (eBOSS) was developed. Using the survey system, experts' views on nuclear energy were tallied, analyzed and compared with the public's. Based on the survey results, the paper suggests some recommendations about the future direction of the public information program in Korea

    2016-01-01

    After having briefly outlined that introducing a relationship between geography and nuclear energy is a quite recent approach, and by often quoting a researcher (Teva Meyer) specialised in Swedish energy issues, the author briefly discusses how nuclear energy structures territories through meshing and 'polarisation' effects, and economic and social impacts. He also discusses whether territories then become dependent on nuclear activity, what happens when a nuclear plant stops, how the existence of a nuclear plant becomes an identity market for a territory, and how material flows also deal with geography. In the last part, the author notices that in Germany, nuclear industry is considered as an industry like any other one. He finally outlines that geography could be useful to achieve energy transition

  14. Nuclear energy and the greenhouse problem

    Kemeny, L.G.

    2001-01-01

    Last November - almost in parallel with the Hague Meeting on Climate Change - more than 1,500 of the world's top nuclear scientists and energy technologists met in Washington DC, at the Joint Conference of the American Nuclear Society, the European Nuclear Society, the Nuclear Energy Institute and the International Nuclear Energy Academy. Unlike the United Nations follow up to the Kyoto protocol, which ended in disarray, a note of high optimism and informed realism pervaded the nuclear conference which, among its multiple streams of subject material and papers by international experts, carried the two main themes of Long Term Globally Sustainable Energy Options and Nuclear Energy and the Greenhouse Problem. This paper considers the immense contribution to Greenhouse gas emission minimisation made by nuclear energy in 1999. In that year the global electricity production by the world's 435 nuclear power stations was 2,398 TWh or 16% of total electricity generation or 5% of total primary energy production. The amount of avoided carbon dioxide emission because of the use of nuclear energy in 1999 was 2.4 billion tonnes. This is 10% of total emissions. Japan's 54 nuclear power stations alone save the equivalent of Australia's total Greenhouse emissions. The secret of this success is Australia's uranium fuel

    2006-10-15

    The author discusses the different important events, notably within the context of energy policy and in relationship with economical factors, which concern the nuclear sector and occurred within the past few years in the United States (since 2001). He describes the failure of the 'all-gas' strategy, the strengthening of the nuclear sector since 2001 (evolution of the stock availability, of operators, of production). He discusses the role of the federal State in the re-launching of nuclear energy by facilitating the licensing procedure for new reactors and by addressing the waste storage issue. He comments the adoption of the global bill on energy (EPAct 2005) and the freezing of the Yucca Mountain storage site. This last aspect promotes the interest in waste transmutation and in related programs, and the implementation of the GNEP (global nuclear energy partnership) which notably proposed an international approach to limit an uncontrolled proliferation of nuclear cycle technologies

  17. Nuclear and energy policy in Korea. Unchanging illusion of nuclear energy and citizens' challenge

    International Nuclear Information System (INIS)

    Leem, S.J.

    2006-01-01

    Korea is the tenth largest energy consumer in the world; the country ranks sixth in oil consumption, seventh in electricity consumption, and ninth in total CO2 emission. Korea now has 20 reactors in operation, nuclear power producing about 40% of its electricity. Its generating capacity from nuclear power plants is the sixth largest in the world; Korea currently exports nuclear technology. The rapid growth of this industry is attributed to extensive subsidy and protection from the Korean government; supported by government-initiated programs a powerful interest group, which consists of nuclear industries, technocrats, and governmental organizations concerned with nuclear policy, now exerts a major influence upon Korea's energy policy for nuclear expansion. Korea's nuclear power policymakers have, however, met opposition since End of the 1980s. The government's attempt to build a nuclear waste repository has provoked strong resistance from environmental movements and local citizens. Even if the government recently succeeded in designating Kyoungju as the nuclear waste site, the nuclear waste issue has awakened public interest in nuclear problems and strengthening public denunciation of Korea's expansive nuclear power policy. In addition, the activation of the Kyoto Protocol in February 2005 has impelled the government to redirect its energy policy towards a sustainable direction. This article focuses on the status and perspectives of Korea's nuclear power policy, enabling a discussion of the degree to which Korea's nuclear and energy policy has changed yet in many ways remains unchanged.

  19. Nuclear energy in the future

    International Nuclear Information System (INIS)

    Chaussade, J.P.

    1994-01-01

    Nuclear energy plays a major role in the French economy because of the lack of fossil fuels on the French territory. About 75% of the French electric power is of nuclear origin. This paper gives an analysis of the French public attitude about nuclear energy and the methods used by the nuclear industrialists to better the electro-nuclear image. Communication, advertising and transparency are the best attitudes for a suitable public information and are necessary to reduce the public anxiety after the Chernobyl accident. Television advertising, magazines and organized visits of nuclear installations have allowed to explain the interest of nuclear energy in the environmental reduction of pollutants. However, public information must include the topic about nuclear wastes to remain credible. (J.S.)

  1. SGS Modeling of the Internal Energy Equation in LES of Supersonic Channel Flow

    Science.gov (United States)

    Raghunath, Sriram; Brereton, Giles

    2011-11-01

    DNS of fully-developed turbulent supersonic channel flows (Reτ = 190) at up to Mach 3 indicate that the turbulent heat fluxes depend only weakly on Mach number, while the viscous dissipation and pressure dilatation do so strongly. Moreover, pressure dilatation makes a significant contribution to the internal energy budget at Mach 3 and higher. The balance between these terms is critical to determining the temperature (and so molecular viscosity) from the internal energy equation and so, in LES of these flows, it is essential to use accurate SGS models for the viscous dissipation and the pressure dilatation. In this talk, we present LES results for supersonic channel flow, using SGS models for these terms that are based on the resolved-scale dilatation, an inverse timescale, and SGS momentum fluxes, which intrinsically represent this Mach number effect.

    1976-01-01

    With reference to the public discussion which is taking place at the moment concerning the future of nuclear energy in the UK, the document from the Advisory Council on Research and Development for Fuel and Power and also the report of the Royal Commission on Environmental Pollution are considered. Although there have been many other projections of UK and world energy requirements prepared by many different organisations, few cover such a wide range of scenarios in such detail as the ACORD report. The Royal Commission report contains many reassuring findings on the more extreme claims of the worldwide anti-nuclear movement, but one cannot read it without gaining the impression that the nuclear option is the energy source they would most like to do without. It is felt that against this background, it would seem to be time for the power industry to stop defending nuclear energy as an acceptable necessity and rather promoting it as the best energy option.

  4. Nuclear hybrid energy infrastructure

    Energy Technology Data Exchange (ETDEWEB)

    Agarwal, Vivek; Tawfik, Magdy S.

    2015-02-01

    The nuclear hybrid energy concept is becoming a reality for the US energy infrastructure where combinations of the various potential energy sources (nuclear, wind, solar, biomass, and so on) are integrated in a hybrid energy system. This paper focuses on challenges facing a hybrid system with a Small Modular Reactor at its core. The core of the paper will discuss efforts required to develop supervisory control center that collects data, supports decision-making, and serves as an information hub for supervisory control center. Such a center will also be a model for integrating future technologies and controls. In addition, advanced operations research, thermal cycle analysis, energy conversion analysis, control engineering, and human factors engineering will be part of the supervisory control center. Nuclear hybrid energy infrastructure would allow operators to optimize the cost of energy production by providing appropriate means of integrating different energy sources. The data needs to be stored, processed, analyzed, trended, and projected at right time to right operator to integrate different energy sources.

    Laponche, Bernard

    2013-05-01

    In the first part of this report, the author outlines and comments the need of an energy transition in the world: overview of world challenges (world energy consumption and its constraints, a necessary energy transition, new actors and new responsibilities), and describes the German example of an energy transition policy. In the second part, he presents and discusses the main reasons for phasing out nuclear: description of a nuclear plant operation (fission and chain reaction, heat production, production of radioactive elements, how to stop a nuclear reactor), safety and risk issues (protection arrangements, risk and consequence of a nuclear accident), issue of radioactive wastes, relationship between civil techniques and proliferation of nuclear weapons. In a third part, the author proposes an overview of the energy issue in France: final energy consumption, electricity production and consumption, primary energy consumption, characteristics of the French energy system (oil dependency, electricity consumption, and high share of nuclear energy in electricity production). In a last part, the author addresses the issue of energy transition in a perspective of phasing out nuclear: presentation of the Negawatt scenario, assessments made by Global Chance, main programmes of energy transition

    In common with many of the issues surrounding nuclear energy, there is some truth in the popular claim that nuclear energy is 'not economic', but this is far from being a universal truth. This paper puts forward the view that, overall, nuclear energy can be a competitive source of electricity and a realistic economic option for the future. (author)

    Since the very beginning of its brief history, nuclear energy was doomed to public attention - because of its first application. For 50 years of existence it failed to become one of traditional energy technologies, which the society would assess on the basis of its actual advantages (such as energy efficiency, resource availability and environmental acceptability). Nuclear weapons and crisis of confidence resulting from severe accidents have both formed the attitude to nuclear. This paper considers the basic antinuclear arguments, such as proliferation, waste and severe accidents. The current status of relations between nuclear energy and the public is still close (not only in Russia, but also in almost all European countries) to this state of politicization of nuclear and constant irrational fear radiation causes among people. Nevertheless, the positive trend in the attitude towards nuclear energy is obvious, both in Russia and in the world. In 2006, the long-expected 'new nuclear energy policy' (with returned budgetary financing of the new nuclear build) was announced in Russia at the highest governmental level. After that the worldwide recognition of the need to develop nuclear energy was only growing. The scale of global energy development is so large that all sources capable of making a contribution will find their demand. In the same time, public opinion in the world inseparably connects the issue of energy security with measures to combat climate changes. The '2 deg. C problem', if solvable at all, could be addressed only by simultaneous implementation of all possible emission reduction measures (including carbon-free energy technologies) on an unprecedented scale. Emission-free nuclear energy can actually become a system capable of sustainable and prompt development. This paper considers the issues, which could hamper nuclear development and negatively impact the public attitude towards nuclear. (authors)

    Nuclear reactions obtained by irradiation in {gamma} Bremsstrahlung, {alpha} particles and protons are particularly suitable for dosing very small traces of light elements. We consider the possibilities presented by activation in {gamma} radiation of 28 MeV maximum energy, mainly for the measurement of C, F, N, O, P and S. Non-destructive methods of analysis for beryllium are described. Under certain conditions they may also be used for other elements such as B, Ca, Li and Na. We give also the results of our first experiments carried out in an attempt to find a method for dosing carbon and oxygen by irradiation in {alpha} particles and protons. For each type of activation the possible types of interference with other nuclear refections are considered.

    2002-01-01

    Public opinion surveys have been carried out since 1998 on what phase and on what extent of the perception of nuclear energy differs between Japanese dwelling in energy supplying region and an energy-consuming region. Southern Fukui rural district where 15 nuclear reactors are now installed and Osaka urban region of about 100 km apart from Fukui were selected as the respective targets for the energy supplying and consuming regions. Analyses of the data of about 3000 samples have revealed the followings. (1) The public in the nuclear energy supplying region are very friendly to nuclear energy so that only about 20 and 39 of the public are resistive to the general promotion of nuclear energy in Japan and to the construction of another nuclear reactor in their dwelling region, respectively. (2) On the other hand, in the energy-consuming region those respective fractions are 41 and 70 implying strong resistance to nuclear energy in the urban region. (3) Both the degree of interest in and the degree of knowledge on nuclear energy are very low, whereas the extent of fear to nuclear is high for the urban public. (4) Not only the fraction of the public who are satisfied with their present life, but the public fraction who is eagerly support the thought of return-to-nature are very high in the urban region. (5) On the other hand, in the energy supplying region, many peoples eagerly want their life to become more convenient than it is now, and 6) all those trends (I)-(5) are revealed more pronouncedly in the woman than the man. The perception gap of nuclear energy thus became clear between Japanese dwelling in rural and urban regions. On the basis of this knowledge, discussions on the nature of the so-called NIMBY will be made from the socio-psychological viewpoint and propositions will also be made on the methods to dissolve the perception gap of that soft.

    This paper summarizes the key points of a report titled Nuclear Energy Outlook, published in 2008 by the Nuclear Energy Agency of the Organization for Economic Cooperation and Development, which has 30 member nations. The report discusses the commitment of many nations to increase nuclear power generating capacity and the potential rate of building new electricity-generating nuclear plants by 2030 to 2050. The resulting decrease in carbon dioxide emissions from fossil fuel combustion resulting from an increase in nuclear power sources is described. Other topics that are discussed include the need to develop non-proliferative nuclear fuels, the importance of developing geological disposal facilities or reprocessing capabilities for spent nuclear fuel and high-level radioactive waste materials, and the requirements for a larger nuclear workforce and greater cost competitiveness for nuclear power generation.

    Nuclear power currently produces over 628 M tep of the generated energy in 1997 avoiding about 1978 Mt of CO 2 emission and gives a significant contribution to reducing greenhouse gas emission. The competitive position of nuclear power might be strengthened, if market forces or government policy were able to give energy security and to control greenhouse gas, relying upon market mechanism and including environmental costs in economic analysis. In this case, taking into account the entire up-stream and down-stream chains for electricity generation, it can be seen that the greenhouse emission from nuclear plants, is lower than that of renewable energy chains. This paper investigates the potential role of nuclear power in global energy supply up to 2020 and analyzes the opportunities and the challenges for research, governments and nuclear industries of a broad nuclear power development in response to environmental concerns. The authors think that nuclear energy will have to compete in the same framework and under the same conditions as all other energy sources and so analyze the possibility of re-launching nuclear energy: it will have to couple nuclear safety and economic competitiveness [it

  1. Society response to nuclear energy

    Energy demand in the world is growing increasingly, among other factors due to economic development. Every way of producing electricity has got their own drawbacks and has implicit environmental impact. Among all the energy sources, nuclear energy is the most polemic because of the way it is presented by the mass media. This aspect provokes controversy to occidental societies which reject this kind of energy with arguments normally based on a wrong and insufficient knowledge of the matter. The antinuclear discourse, promoted late in the seventies, has gone deeply into the collective social unconscious and has undermined public acceptance of nuclear energy due to the fact, deeply exploited by antinuclear groups, of linking nuclear energy with the atomic bombing of Hiroshima and Nagasaki. In this sense, it is important to mention that in Japan there was a profound resentment and opposition to nuclear energy, because the memory of the nuclear bombings was permanently alive. However when the Japanese government told its people that this energy was necessary to boost their industrial development, Japanese citizens in an unprecedented attitude of patriotism overcame their most antagonist feelings, in order to contribute to the industrial development of their country. The result was that most of them voted in favour. Presently Japan gets 30% of its energy by means of 56 nuclear power plants and 1 more is under construction. Antinuclear groups took as their best emblem the accident of Chernobyl to justify their opposition to the nuclear power plants. The manipulation of this accident has been one of the most shameful in the nuclear history. It is widely known among the experts that the reactor used in Chernobyl was a type of military plutonium converter with a positive temperature reactivity coefficient, which made very dangerous its functioning. Any nuclear regulatory commission in democratic and responsible countries would have never authorized the use of this reactor

    This is a comment on an article by Prof. Haerle a theologist, published earlier under the same heading, in which the use of nuclear energy is rejected for ethical reasons. The comment contents the claim mode by the first author that theologists, because they have general ethical competency, must needs have competency to decide on the fittest technique (of energy conversion) for satisfying, or potentially satisfying, the criteria of responsible action. Thus, an ethical comment on, for instance, nuclear energy is beyond the scope of the competency of the churches. One is only entitled as a private person to objecting to nuclear energy, not because of one's position in the church. (HSCH) [de

  6. Religious organizations debate nuclear energy

    Dowell, T.

    1984-08-01

    This paper reviews the history of the religious debate on nuclear energy over the last thirty years. In the 1950s, religious statements recognized the peaceful uses of atomic energy as a blessing from God and called upon world leaders to promote its use. Nuclear energy programmes were launched in this decade. In the 1960s, there was still religious approval of nuclear energy, but questions about ethics arose. It was not until the 1970s, after the oil crisis, that serious questioning and criticism of nuclear energy emerged. This was particularly true in the United States, where the majority of statements originated - especially in 1979, the year of the Three Mile Island accident. Around this time, the World Council of Churches developed the concept of the just, participatory and sustainable society. The meaning and use of these terms in the nuclear energy debate is examined. This paper also compares the balanced debate of the World Council with the case against the plutonium economy prepared by the National Council of the Churches of Christ in the USA. Three religious statements from the 1980s are examined. A United Church of Canada resolution, critical of nuclear energy, is compared with a favourable report from the Methodist Church in England. Both use similar values: in one case, justice, participation and sustainability; in the other case, concern for others, participation and stewardship. There are not many Catholic statements on nuclear energy. One which is cautious and favourable is examined in detail. It is concluded that the use of concepts of justice, participation and sustainability (or their equivalents) has not clarified the nuclear debate

    Over two thirds of the population (68%) believe that nuclear energy is necessary to secure the supply of power. This is one of the results of a representative poll conducted by the Demoscopic Institute Allensbach on behalf of the Nuclear Energy Information Circle of the German Atom Forum. 78% of the population are of the opinion that the power supply is secure for the next 20 years. The significance of nuclear power in today's power supply is, however, grossly underestimated. For example 30% of respondents put the number of nuclear power plants in the Federal Republic at four at the most. Many more people than one year ago are now convinced of the environmental compatibility of nuclear power plants. The public debate on nuclear energy is generally judged critically by politicians, journalists and experts: factual and emotional. 54% of the population and 71% of politicians interviewed regard the question of nuclear energy utilisation as a predominantly political decision. Questioned was a representative sample of the population which included politicians, journalists, scientists and energy economists. The results, which were presented at a press conference in Bonn by the economist Renate Koecher, are reviewed. (orig.) [de

    Nuclear energy was born in World War II and it has grown within the regime of Cold War. When the Cold War came to the end around early 1990 s, we who have benefited by the development of nuclear energy must have been challenged with a new tide of civilization change. Although it has not been so much closely questioned since then, such a new movement, that was submerging, abruptly manifested on September 11, 2001. Then, many of us realized that global circumstances, especially concerned with security, must have actually changed with the reordering of the world basic structures. This paper describes on the thoughts to reveal the cause and background of the event on September 11 with the linkage to nuclear energy development, or nuclear civilization in pursuit of the future regime of nuclear in harmonization with the global society in 21st century.

    The Government's views on the development of nuclear energy are outlined. In this country, we continue to see some important advantages in maintaining nuclear power generation. It increases diversity, and so helps to maintain security of energy supply. It does not produce greenhouse gases or contribute to acid rain. But it is equally clear that nuclear costs must be brought under control whilst at the same time maintaining the high standards of safety and environmental protection which we have come to expect in the UK. The three main elements which the nuclear industry must address in the future are summarized. First the costs of nuclear generation must be reduced. Secondly, once the feasibility and costings of PWRs have been established consideration must be given to the choices for the future energy policy and thirdly new reactor designs should be standardized so the benefits of replication can be realised.

    The contribution takes it that the assumption, acceptance problems of nuclear energy are based on information deficit, is groundless in the end. It is true that there is a big knowledge gap between the nuclear energy experts and the broad public, empirical investigations, however, point out that increased knowledge would by no means go along with increased nuclear energy acceptance in the population. Also, the interpretation pattern 'Science and technology hostility' is not good enough to explain the nuclear energy controversy, because nuclear energy opponents oppose nuclear energy in an increasingly professional manner, and as an alternative they do not propagate renunciation of technology but another kind of energy technology. The degree of intensity and the long duration of the nuclear energy controversy in the Federal Republic of Germany in international comparison is defined by 1. little willingness in the 'interest block' in state, industry and nuclear research in favour of speeding up nuclear energy expansion, to yield to the requirements of the anti-nuclear-energy movement, and 2. factual possibilities of the ecological movement, also without parliamentary majority, to hinder the nuclear energy program and, consequently, to influence political decisions. In addition, social peripheral conditions play a role. (orig./HSCH) [de

    The energy loss effect in nuclear matter, which is a nuclear effect apart from the nuclear effect on the parton distribution as in deep-inelastic scattering process, can be measured best by the nuclear dependence of the high energy nuclear Drell-Yan process. By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the measured Drell-Yan production cross sections for 800 GeV proton incident on a variety of nuclear targets are analyzed within the Glauber framework which takes into account the energy loss of the beam proton. It is shown that the theoretical results with considering the energy loss effect are in good agreement with the FNAL E866 data. (orig.)

    Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

    During his recent tour of North America, Australian Prime Minister John Howard called for a 'full-blooded debate' about the place of nuclear power in the nation's energy mix. 'I have a very open mind on the development of nuclear energy in my own country,' he said. Treasurer Peter Costello said that only economic arguments precluded Australia's move to nuclear energy. 'If it becomes commercial, we should have it,' he said on 23 May. But in reality the 'debate' had already been adjudicated. Three days later the Australian Nuclear Science and Technology Organisation (ANSTO) presented Science Minister Julie Bishop with a report that delivered Costello's economic justification for nuclear power

  19. Nuclear energy and public opinion. Chilean Nuclear Energy Commission (CCHEN) dissemination and extension program

    International Nuclear Information System (INIS)

    Oviedo, Gonzalo Torres; Quintana, Rosamel Mufioz

    2000-01-01

    In Chile, demand for electricity will soon exceed water resources. The country will then face severe energy dependence, with very little control over generation costs, and with increasing emission of contaminating gases into the atmosphere. Nuclear energy may be considered an appropriate and stabilizing alternative for the system in the medium term, the benefits of nuclear generation to be thus extended to a country which has a moderate demand for electricity. This new scenario will require an additional technical and regulating effort by CCHEN and by the state, as well as re-orientation of their activities in connection with public opinion. The Public Nuclear Energy Education Program, initiated in 1976 by CCHEN, has been developed for purposes of achieving public acceptance of nuclear energy as a way of facilitating development of various activities which pertain to CCHEN's scope of action, and of creating a climate which is favorable to acceptance of nuclear energy as an alternative source of energy. Thus, the object is that the public draw informed conclusions on the benefits and risks implicit in the use of isotopes, radiation, and nuclear power generation. The Program consists of activities for high school students aimed at vocational orientation of those who stand out in the science area, training and extension activities for teachers, journalists, and professionals, a program of guided tours of the nuclear centers, a publicity campaign conducted in the various media and, since 1980, massive distribution of brochures and magazines. There are no declared anti-nuclear movements in Chile. Nevertheless, there are opinions against nuclear power in different relevant sectors. Lately, the social communication media have preferred CCHEN as their source of information, a fact which makes it possible for the latter to have access to good coverage of its activities

  20. The role of nuclear energy in times of energy transition

    International Nuclear Information System (INIS)

    2012-01-01

    Since the reactor catastrophe in Fukushima, the risk of nuclear power has once again become more evident to the public and has also led to a rethinking of politics in Europe. Slogans like ''Nuclear Power, No Thanks!'', ''Get Out of Euratom'' are making more and more the rounds. The phase-out of nuclear energy is the topic that is increasingly provoking people to think. But how should one handle this? What role will nuclear energy play in a distant future? Central factors such as the economic viability of renewable energy sources and the environmental and social compatibility of production and distribution must be taken into account, while at the same time the reduction of pollutants and greenhouse gases must continue. If this is done without nuclear energy, is the rapid abandonment of nuclear energy even necessary or does nuclear energy generation have to be used as a temporary solution? (roessner)

    Finland currently generates about 40% of its electricity from nuclear power. This achievement of worldwide record magnitude is based on long-lasting efforts to build and maintain the competent infrastructure and close international cooperation required by this demanding technology. This booklet published by the Finnish Atomic Energy Commission gives an overview of nuclear energy and related organizations in Finland. It describes the utility companies and nuclear power production, the manufacturing industry and its export potential, research and educational activities and the legal framework and authorities for nuclear safety and administration. International cooperation has been essential for Finland in developing its nuclear energy capacity and appreciation is espressed to many countries and international organizations which have contributed to this. At the same time Finnish organizations are willing to share the experiences and know-how they have gained in building nuclear power in a small country. This is a road which will be followed by many other countries in the decades to come. It is hoped that this booklet will also help to open new channels of cooperation in such efforts

    The Swiss energy supply is one-sided and depends strongly on foreign countries. Therefore, the mineral oil share of about 70% and the import share of more than 80% should be decreased and substituted respectively. The electricity is one of the most important mineral oil alternatives. Today, this energy is produced at 30% in nuclear plants. For covering the moreover increasing demand of about 4%/year a 1000 MW nuclear power plant is under construction and two further plants are in advanced planning situation. The general conditions for the future extension of nuclear energy have been defined for 1979 in a supplement of the atomic law of 1959, approved by a plebiscite. Shortly before that event an initiative against nuclear energy was defeated. The statements are completed with some aspects of waste elimination, environment protection and economy of nuclear energy in Switzerland. (Auth.)

    The raise of the nuclear physics came with heavy mathematical developments. The analogical installations became especially useful for precise calculations of parameters which depend the running of a reactor. They permit between other to study of kinetic problems and especially ''cybernetics'' of nuclear reactors. It doesn't make a doubt that their use will become widespread, not only in the calculations laboratories, in services for servo-mechanisms study, but also in the control panels of the reactors themselves. (M.B.) [French] L'essor de la physique nucleaire s'est accompagne de lourds developpements mathematiques. Les montages analogiques sont devenus particulierement utiles pour les calculs precis des parametres dont depend le fonctionnement d'un reacteur.

Il ne fait pas de doute que leur usage se generalisera, non seulement dans les laboratoires de calculs, les services d'etudes de servomecanismes, mais aussi pres des tableaux de commande des reacteurs eux-memes.

    Nuclear Energy for New Europe - what does it mean? New Europe - it means in first order joined Europe. And it is quite clear that also efforts in nuclear energy must be joined. What can be proposed as a target of joint efforts. Improvement of existing plants, technologies, materials? - Certainly, but it is performed already by designers and industry themselves. There exists a problem, which each state using nuclear energy faces alone. It is nuclear waste problem. Nowadays nuclear waste problem is not completely solved in any country. It seems reasonable for joining Europe to join efforts in solving this problem. A satisfactory solution would reduce a risk connected with nuclear waste. In addition to final disposal problem solution it is necessary to reduce total amount of nuclear waste, that means: reducing the rates of accumulation of long-lived dangerous radionuclides; reducing the existing amounts of these radionuclides by transmutation. These conditions can be satisfied in reasonable time by burning of minor actinides and, if possible, by transmutation of long-lived fission products. However we can use this strategy effectively if we will design and construct nuclear energy as a system of which components are united by nuclear fuel cycle as a system-forming factor. The existing structures and approaches may become insufficient for new Europe. Therefore among the initial steps in considering nuclear waste problem must be considering possible promising fuel cycles for European nuclear energy. So, does new Europe need new nuclear energy? It seems, yes. (author)

    A great deal of energy will be needed for industrial development. The risks of energy production can be either individual or social in nature. Individual risk occurs in different places and different times to individuals in a certain period of time. Social risk occurs to several people in a time. People tend to refuse a nuclear power plant because of its social risk. This attitude is based more on feelings than reason. In fact radiation from a nuclear power plant is only 0.15% while radiation from medical instruments and from the environment is 99%. From the safety, pollution effect, price, and uses point of view, it can be concluded that nuclear energy is the most appropriate energy to face the future of the nation. (RUW)

    Basing on our present knowledge the following energy sources for energy supply must be taken into consideration in the long term: regenerative energy sources, fission energy gained by breeder reactors, nuclear fusion. While regenerative energy sources were treated at full length in the study 'Energy Sources for Tomorrow' the present study specifies the other two energy options. The availability and the reliability of nuclear primary energy carrier supply is described in detail and the conversion systems available or still being developed are investigated with regard to their specific consumption of primary energy. Topical questions concerning the proliferation stability of the fuel cycles and techniques are subject to the INFCE program. With reference to the nuclear energy documentation activities of the Federal Government this study is supposed to supply further fundamental material on nuclear primary energy carriers, consumption and readiness for application. Thus it will contribute to the question: 'Is nuclear energy an option which guarantees energy supply in the long term for the Federal Republic of Germany'. (orig.) 891 UA 892 ARA.

    2007-01-01

    In the course of the current discussion on promoting the economical competitiveness of sustainable energy systems, especially renewable and non-CO 2 -intensive ones, interest in nuclear energy has re-awakened in Europe (''nuclear renaissance''). This paper starts with presenting the concept of energy sustainability and its main elements. Next, an overview of the main results of sustainability assessments for different energy supply options (nuclear, fossil, renewables) covering full energy chains is given. Nuclear energy's typical strong and weak points are identified from a sustainability point of view. On the basis of these results, it is argued that more emphasis on nuclear energy's (very good) total cost performance, i.e. incl. externalities, rather than on its (very good) contribution to combating climate change would stronger benefit its ''renaissance''. Finally, the development of an overall EU-wide framework is proposed in order to assess the sustainability performance of alternative energy supply options, incl. nuclear, across their lifecycle and thus support decision making on developing sustainable energy mixes.

  13. Public attitudes to nuclear energy

    1984-09-01

    The last decade has seen a marked increase in public concern about nuclear energy. As a consequence, it is now recognized that the future of nuclear energy will not only depend on technical and economic factors, but that public acceptability of this technology will play a crucial role in its long-term future. This paper summarizes trends in public reactions to nuclear power in various countries and discusses a number of studies on public beliefs and attitudes to nuclear power in general, and to the building of a nuclear power plant near to one's home. It is concluded that the qualitative aspects of the possible risks of nuclear energy play an important role in the public's perception of this technology. It is also clear, however, that differences in perception of the risks do not embrace all the relevant aspects of the public's assessment of nuclear energy. Public reaction is also related to more-general beliefs and values, such as emphasis on economic versus social priorities, attitudes to technology and environmental concern. 11 references.

    Hauff, V.

    1986-01-01

    The author states four points against nuclear power: 1. Although the probability of a catastrophic accident is very low, the consequences will be enormous. 2. Extension of the nuclear power generation worldwide will increase the danger of proliferation of nuclear weapons. 3. Decommissioning of nuclear power plants and disposal of nuclear waste will be a problem for many generations. 4. Protection of nuclear facilities may lead to the eventual abandonment of the civil rights assured by law. The author gives priority to energy conservation; he states that an 80% utilization factor is achievable in cogeneration and district heating. He agress with C.F. Weizsaecker on the long-term relevance of solar energy as the main energy source, which would also help to reduce the CO 2 problem (heat-up of the earth atmosphere, destruction of tropical forests). Energy supply without nuclear power plants would also provide new jobs, since there is no energy source as capital-intensive and low in staff requirements as nuclear power. (GL) [de

    The interest shown by the European Institutions in the energy debates, in which the nuclear energy is included as a key component within the energy mix, is obvious. Climate change and energy supply have pushed some countries to publicly express their interest for developing the nuclear energy. These positions are however in contradiction with some others within the European Union which are a lot more critical towards this type of energy and where face-out policies still prevail. Despite the fact that the use of the nuclear energy will remain within the competence of each Member State, the European Union will continue to play a prominent role in the development of an energy strategy based on a low carbon economy.

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.' One way this objective is achieved is through the publication of a range of technical series. Two of these are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III.A.6 of the IAEA Statute, the safety standards establish 'standards of safety for protection of health and minimization of danger to life and property'. The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are written primarily in a regulatory style, and are binding on the IAEA for its own programmes. The principal users are the regulatory bodies in Member States and other national authorities. The IAEA Nuclear Energy Series comprises reports designed to encourage and assist R and D on, and application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia, and government officials, among others. This information is presented in guides, reports on technology status and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The IAEA Nuclear Energy Series complements the IAEA Safety Standards Series. Nuclear generated hydrogen has important potential advantages over other sources that will be considered for a growing hydrogen share in a future world energy economy. Still, there are technical uncertainties in nuclear hydrogen processes that need to be addressed through a vigorous research and development effort. Safety issues as well as hydrogen storage and distribution are important areas of research to be undertaken to support a successful hydrogen economy in the future. The hydrogen economy is gaining higher visibility and stronger political support in several parts of the

    Dr. Agnew notes that the public fails to remember that the electric utilities and equipment manufacturers did not invent nuclear energy; they only choose whether or not to use it to generate power. The effort to regain world leadership in nuclear energy will require recognizing that the rest of the world needs it too. Opposition to the use of nuclear power has been politically effective, in spite of the need to move to a non-petroleum fuel base and without coming up with a viable alternative. The nuclear industry responded to the Three Mile Island accident by taking steps to improve reactor safety, but the industry continues to be threatened because of the suspended reprocessing and breeder programs. The industry must make a compelling case for energy independence to persuade the public that all energy sources, including nuclear, must be developed

    While nuclear energy appears today as a powerful and carbon-free energy, it generates at the same time doubts and apprehension in the general public. Are these fears justified? Is France the most advanced country in the nuclear domain? Should we fear a Chernobyl-like accident in France? Is any irradiation dangerous? What would be the consequences of a terror attack against a reactor? Will nuclear energy be powerful enough to take up the energy reserves challenge? Will the waste management and the nuclear facilities dismantlement be extremely expensive in comparison with the electricity production costs? Do we know how to manage nuclear wastes on the long-term? This book tries to supply some relevant arguments in order to let the reader answering these questions himself and making his own opinion on this topic. (J.S.)

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

    2004-01-01

    Relations between nuclear energy and security concepts can be clarified through investigation into the multivocal nature of security concepts. While military uses of nuclear energy significantly influence national security, peaceful uses of nuclear energy contribute energy security, which is an expanded concept of national security. Military and peaceful uses of nuclear energy have reciprocal actions, thus influencing national security and energy security, respectively. Nuclear security, which means security of nuclear systems themselves, recently attracts the attention of the international society. Nuclear security directly influences national security issues. On the other hand, along with nuclear safety, nuclear security becomes a prerequisite for energy security through peaceful uses of nuclear energy. In investigating into relations between nuclear energy and security concepts, the difficulty of translating the English word of 'nuclear security' into Japanese as well as other languages is found.

    An extension in the use of energy, on even a fairly moderate basis, will, for several decades at least, require the use of all our present energy sources at rates that are a natural extension of historical rates, trending toward maximum practicable exploitation for all but nuclear energy. Regardless of what happens with the fossil hydrocarbons nuclear energy will play a major role in the supply of energy. When the fossil hydrocarbons have run their course nuclear and possibly some solar energy, through the media of electricity, hydrogen and synthetic hydrocarbons, will provide the bulk of the world's controlled energy and in sufficient quantity to provide ample energy for all. The burning question, however, is what will happen in the next few decades. There is a wonderful opportunity for nuclear energy, as the world requirement for energy, and particularly electrical energy, grows

    Gagarinskiy, Andrey

    2008-01-01

    The paper considers the world energy demand till the middle of the century, as well as possible forecasting solution for this challenge. On the base of the mathematical model developed in the Kurchatov Institute in 2003- 2006, the vision of the global nuclear energy system and its potential contribution in the energy mix was analyzed. The rate of rapprochement between specific energy consumptions in different countries of the world is a key parameter determining the energy market strain. It was shown that a continuation of the current world trends of this rapprochement would result in an energy resource deficit already in the nearest future. The energy mix picture would contain an 'unsatisfied demand' area of about 10 000 Mtoe of total energy to be consumed by the mid-century Supposing that the mankind has to meet the 'unsatisfied demand' by nuclear energy, the global energy challenges of the 21. century energy do not impose any upper limit on nuclear energy development, the scale of which would be determined by development opportunities. Russia, as one of the pioneers of the First Nuclear Era, possesses great experience of solving the key issues of nuclear energy of the 20. century, and is capable to play an important role in dealing with the challenges faced by nuclear in the 21. century.

    An analysis is given of the consequences resulting from the Dutch government's decision to use both coal and uranium for electricity production. The energy yields are calculated for the total conversion processes, from the mine to the processing of waste and the demolition of the installations. The ecological aspects considered include the nature and quantity of the waste produced and its effect on the biosphere. The processing of waste is also considered here. Attention is given to the safety aspects of nuclear energy and the certainties and uncertainties attached to nuclear energy provision, including the value of risk-analyses. Employment opportunities, the economy, nuclear serfdom and other social aspects are discussed. The author concludes that both sources have grave disadvantages and that neither can become the energy carrier of the future. (C.F.)

    2011-01-01

    The accident at the Japanese nuclear power plant Fukushima in March 2011 triggered a debate about phasing out nuclear energy and the safety of nuclear power plants. Several states are preparing to end nuclear power generation. At the same time the operational life time of many nuclear power plants is reaching its end. Governments and utilities now need to take a decision to replace old nuclear power plants or to use other energy sources. In particular the requirement of reducing greenhouse gas emissions (GHG) is used as an argument for a higher share of nuclear energy. To assess the contribution of nuclear power to climate protection, the complete life cycle needs to be taken into account. Some process steps are connected to high CO2 emissions due to the energy used. While the processes before and after conventional fossil-fuel power stations can contribute up to 25% of direct GHG emission, it is up to 90 % for nuclear power (Weisser 2007). This report aims to produce information about the energy balance of nuclear energy production during its life cycle. The following key issues were examined: How will the forecasted decreasing uranium ore grades influence energy intensity and greenhouse emissions and from which ore grade on will no energy be gained anymore? In which range can nuclear energy deliver excess energy and how high are greenhouse gas emissions? Which factors including ore grade have the strongest impact on excess energy? (author)

    Full text: The activities of Department was engaged in the selected topics in nuclear fission reactor science and engineering. Present and future industry competitiveness, economic prosperity and living standards within the world are strongly dependent on maintaining the availability of energy at reasonable prices and with security of supply. Also, protection of man and the environment from the harmful effects of all uses of energy is an important element of the quality of life especially in Europe. It is unrealistic to assume that the technology for renewable (hydro, wind, solar and biomass) available within a 20-30 year perspective could provide the production capacity to replace present use of nuclear power and at the same time substantially reduce the use of fossil fuels, especially when considering that energy demand in industrialized countries can be expected to continue to increase even within a framework of overall energy conservation and continued improvement of efficiency in energy usage. In the area of nuclear fission, we continue support to maintain and develop the competence needed to ensure the safety of existing and future reactors and other nuclear installations. In addition support is given to explore the potential for improving present fission technology from a sustainable development point of view.

    In deciding the future course of nuclear energy, it is necessary to re-examine man's long-term energy options, in particular solar energy and the breeder reactor. Both systems pose difficultiies: energy from the sun is likely to be expensive as well as limited, whereas a massive world-wide deployment of nuclear breeders will create problems of safety and of proliferation. Nuclear energy's long-term success depends on resolving both of these problems. Collocation of nuclear facilities with a system of resident inspectors are measures that ought to help increase the proliferation-resistance as well as the safety of a large-scale, long-term nuclear system based on breeders. In such a long-term system a strengthened International Atomic Energy Agency (IAEA) is viewed as playing a central role.

    Because primary energies such as fossil fuels, nuclear energy and renewable energy are limited in quantity of supply, it is necessary to use available energies effectively for the increase of energy demand that is inevitable this century while keeping environment in good condition. For this purpose, an efficient synergistic energy conversion process using nuclear energy and fossil fuels together converted to energy carriers such are electricity, hydrogen, and synthetic fuels seems to be effective. Synergistic energy conversion processes containing nuclear energy were surveyed and effects of these processes on resource saving and the CO 2 emission reduction were discussed. (T.T.)

  2. World nuclear energy paths

    Connolly, T.J.; Hansen, U.; Jaek, W.; Beckurts, K.H.

    1979-01-01

    In examing the world nuclear energy paths, the following assumptions were adopted: the world economy will grow somewhat more slowly than in the past, leading to reductions in electricity demand growth rates; national and international political impediments to the deployment of nuclear power will gradually disappear over the next few years; further development of nuclear power will proceed steadily, without serious interruption but with realistic lead times for the introduction of advanced technologies. Given these assumptions, this paper attempts a study of possible world nuclear energy developments, disaggregated on a regional and national basis. The scenario technique was used and a few alternative fuel-cycle scenarios were developed. Each is an internally consistent model of technically and economically feasible paths to the further development of nuclear power in an aggregate of individual countries and regions of the world. The main purpose of this modeling exercise was to gain some insight into the probable international locations of reactors and other nuclear facilities, the future requirements for uranium and for fuel-cycle services, and the problems of spent-fuel storage and waste management. The study also presents an assessment of the role that nuclear power might actually play in meeting future world energy demand

    The last decade has seen a dramatic increase in public concern about nuclear energy. As a consequence, it has become recognized that the future of nuclear energy will not only depend on technical and economic factors, but that public acceptability of this technology will play a crucial role in the long-term future of nuclear energy. Research has shown a considerable divergence in public and expert assessment of the risks associated with nuclear energy. Qualitative aspects of risks play a dominant role in the public's perception of risks, and it seems necessary for experts to recognize this in order to improve relations with the general public. It is also clear, however, that differences in the perception of risks do not embrace all the relevant aspects of the public's assessment of nuclear energy. Public reaction is also related to more general beliefs and values, and the issue of nuclear energy is embedded in a much wider moral and political domain. 8 references.

    The public opinion in the Netherlands about nuclear energy has been rather stable during recent years. Since the Chernobyl accident roughly 60% of the Dutch population is opposed to extension of the use of nuclear energy. Nuclear experts play an important role in the formation of public opinion about nuclear energy. In this paper the social and cultural background of 87 Dutch nuclear energy experts is analyzed with respect to religious belief, age, life style, membership of a political party, birth order and career pattern. 2 figs., 2 tabs., 16 refs

    Full text: Nuclear energy is an established component of electricity supply worldwide (16%) and in particular in OECD (nearly a quarter). It is supported by a mature industry benefiting from extensive experience (more than 8 000 reactor years of commercial operation) and dynamic R and D programmes implemented by governments and industries. Existing nuclear power plants are competing successfully in deregulated electricity markets owing to their low marginal production costs, their technical reliability (availability factors exceeding 80% in many countries) and good safety performance. Stringent safety requirements and radiation protection regulations in place in OECD countries allow potential impacts of nuclear energy facilities on human health and the environment to remain extremely low. Furthermore, nuclear energy, a nearly carbon free source, contributes to alleviating the risk of global climate change (worldwide, GHG emissions from the energy sector are already 8% lower than they would be without nuclear energy). Issues related to high-level waste management and disposal are being addressed in comprehensive, step by step approach. Progress towards the implementation of deep geological repositories is being demonstrated (e.g., Yucca Mountain in the US, Olkiluoto in Finland) and research on innovative fuel cycles aiming at partitioning and transmutation of minor actinides is being actively pursued. Up to 2010-2020, nuclear energy will maintain its role mainly through capacity upgrade and lifetime extension of existing plants, in many cases the most cost effective means to increase power capacity and generation. Examples are provided by utility policies and decisions in a number of OECD countries (e.g., Spain, Sweden, Switzerland, UK, US). Although only few new units are being or will be built in the very near term, their construction and operation is bringing additional experience on advanced evolutionary nuclear systems and paving the way for the renaissance of

    The new energy approach towards nuclear, due to the growing political support at the beginning of this century, is the result of a complexity of economical, social, political and technological factors. The history of peaceful use of nuclear energy in Romania goes back 45 years. Considering the strategic importance of the energy sector in developing the national economy on sustainable basis, the sector evolution should be outlined through prognosis and strategies on different horizons of time, so that the development perspectives and the energy supply to be correctly estimated. This necessity is emphasized in the Governmental Program of the present administration, which takes into consideration Romanian Economic Strategy on medium term and also The Government Action Plan on 2000-2004, agreed with the European Commission. In order to implement the Governmental Program, the Ministry of Industries and Resources elaborates the National Energy Strategy. The Government Action Plan draw up the conclusion that Unit 2 from Cernavoda NPP must be finalized. This solution fits the least-cost energy development planning and answers to environment requirements. Romania became a Member State of the Agency in 1957. From the mid-1960s to the mid-1970s its technical co-operation program with the Agency covered mainly research in nuclear physics and some medical and other applications of radiation and isotopes. Since 1976, when the Romanian nuclear power program was embarking to use CANDU-type reactors, the Agency has supported mainly the activities related to the Cernavoda NPP. In the framework of the Romanian accession process to the European structures, CNCAN co-operates with European Commission for transposition of the communautaire acquis in the field of nuclear activities. Romania has had laws in place governing the regulation of nuclear activities since 1974. They were remained in force throughout and subsequent to the national constitutional changes started in 1989 until 1996

    The electric utility industry has made a substantial commitment to nuclear power. The industrial capability to produce nuclear plants is large and well established. Nevertheless, nuclear energy in the United States is at the crossroad, and the direction it will take is not at all assured. The postponements, cancellations, and lack of orders for new plants over the past three years raise some serious questions about the future. The present problems of nuclear energy are primarily nontechnical in nature. If the nontechnical issues can be resolved, the future for nuclear looks bright indeed. The LWR and other converters could provide strong competition for coal and other electric power options for a half century or more. If development goals are met, the nuclear breeder offers the prospect of a very large supply of energy at stabilized prices over a time span of centuries

  9. How competitive is nuclear energy?

    The economic competitiveness of nuclear energy will be crucial for determining its future share in world electricity production. In addition, the widespread liberalization of power markets, in particular in OECD countries, reinforces the role of commercial criteria in technology selection . The recently published IEA/NEA study on Projected Costs of Generating Electricity: 2010 Edition (IEA/NEA, 2010) provides important indications regarding the relative competitiveness of nuclear energy in OECD member countries as well as in four non-OECD countries (Brazil, China, Russia and South Africa). The results highlight the paramount importance of discount rates and, to a lesser extent, carbon and fuel prices when comparing different technologies. Going beyond this general finding, the study also shows that the relative competitiveness of nuclear energy varies widely from one major region to another, and even from country to country. While the study provides a useful snapshot of the costs of generating electricity with different technologies, it does not provide an absolute picture of the competitiveness of nuclear energy. Like any study, Projected Costs of Generating Electricity makes a number of common assumptions about discount rates as well as carbon and fuel prices. In addition, its calculations are based on a methodology that is referred to as the levelised cost of electricity (LCOE), which assumes that all risks are included in the interest or discount rate, which determines the cost of capital. In other words, neither the electricity price risk for nuclear and renewables, nor the carbon and fuel price risk for fossil fuels such as coal and gas, receive specific consideration. The decisions of private investors, however, will depend to a large extent on their individual appreciations of these risks. The competitiveness of nuclear energy thus depends on three different factors which may vary greatly from market to market: interest rates, carbon and fuel prices, and

    At a time when the nuclear question mobilizes attentions and when a new cycle of debates about non-proliferation opens up, the author recalls the constraints and challenges of a nuclear power generation policy. After a brief history of the development of nuclear energy in France and in the rest of the world, the author presents the risks linked with this energy source (TMI and Chernobyl accidents), the particularities of the fuel cycle with its safety and security aspects, and the promises of some past and future reactor technologies (FBR's and fusion reactors). Then, the author stresses on the importance of investments in this domain as illustrated by the launching of new nuclear programs in France, UK, Italy, Finland and in the US, and by the willing of some emerging countries to develop this energy source (China, India, United Arab Emirates, Jordan..). Finally, nuclear energy must not be considered as a privilege of developed countries but should benefit to the rest of the world as well since it promotes economic development thanks to an abundant and cheap energy.

    In the first part are studied the general relationships between the physical effects produced by neutrons in solids, and the total flux and neutron energy spectrum; some examples are given. The second part, describes the application to a silicon damage detector whose principle is to use the damage produced in a PIN Junction for measuring the neutron flux (intermediate and fast) received by the detector. Chapter I is devoted to the experimental determination of the energy given to the atoms by a primary in the silicon. The results and conclusions drawn from this determination make it possible to consider, in chapter II, the calculation of the detectors response characteristics.Chapter III deals with the measurement of the detectors response function and it is noted that good agreement is obtained between the calculation and experimental results. The whole of the second part constitutes a test of the methods presented in the first part.

    The paper provides a historical review of the behaviour of Parliament in the discussion about utilizing nuclear energy. An analysis of the positions taken and reasons advanced so far is necessary, because it is only from its results that promising strategies appropriate to bring about a consensus can be derived. There is no doubt that it is a genuine task of the democratically legitimated bodies to strive for a consensus in energy policy, in particular nuclear energy, in the interest of the whole State, with the legislative, executive and economic bodies combining their efforts. The reservedness of Parliament is regrettable. At the moment, however, there is the positive effect of the discussion being revived. It should be conducted rationally in the joint interest of reaching a political consensus and, on that basis, a broad acceptance of nuclear energy utilization. (orig./HSCH) [de

    At the end of 1980 nuclear energy accounted for 9% of the world production of electricity stemming from 262 power stations, utilising mainly the process of water reactors and representing an installed capacity of 142 GWe. This production, apparently limited, already represents the equivalent of 150 million TOE. The 600 nuclear power stations in service, under construction or ordered represent a total of 450 GWe. In 1985, their production ought to cover 15% of the world requirements of electricity, which corresponds to a doubling of the share of nuclear energy within 6 years. During these recent years, the development of nuclear energy has undergone a significant slowing down and the number of orders for new nuclear power stations has dropped considerably in particular in the United States. Considering the time required and the available industrial capacity, the accumulated capacity which could be installed worlwide by 1990 could attain 530 GWe, equivalent to 650 MTOE covering 24% of the world production of electricity and 7% of the world consumption of primary energy. A determined effort for the end of this century could end up by the installation of 1200 GWe of capacity, generating 1.5 GTOE. The share of nuclear energy would then represent 35% of the production of electricity [fr

    Rising expectations best characterize the current prospects of nuclear power in a world that is confronted with a burgeoning demand for energy, higher energy prices, energy supply security concerns and growing environmental pressures. It appears that the inherent economic and environmental benefits of the technology and its excellent performance record over the last twenty years are beginning to tilt the balance of political opinion and public acceptance in favour of nuclear power. Nuclear power is a cost-effective supply-side technology for mitigating climate change and can make a substantial contribution to climate protection. This paper reviews the current status of nuclear power and its fuel cycle and provides an outlook on where nuclear power may be headed in the short-to-medium run (20 to 40 years from now). (auth)

    This study juxtaposes the major facts and arguments about nuclear energy and its potential role in establishing sustainable energy paths. The notion of sustainability has a strong normative character and can be interpreted in a variety of ways. Therefore, also the sustainability of energy supply technologies possesses a normative nature. This paper analyses what the major dimensions are that ought to be addressed when nuclear energy technology is compared, in sustainability terms, with its fossil-fuelled and renewable counterparts. It is assessed to what extent energy supply portfolios including nuclear energy are more, or less, sustainable in comparison to those that exclude this technology. It is indicated what this inventory of collected facts and opinions means for both policy and research regarding nuclear energy in the case of the Netherlands. 32 refs

    In the next years we will face significant switch stands regarding the future energy mix in Europe. In general, European energy policy has to address three energy challenges for a competitive electricity production (1): - Security of supply; - Limitation of greenhouse gas emissions; and - Providing affordable energy to consumers. Regarding climate precaution the goal of a low carbon economy is very ambitious. The NPP in operation already today contribute to all three goals. Nuclear energy generates two thirds of the EU' low carbon electricity, is one of the most economic energy sources and is less vulnerable to fuel price changes, thereby protecting EU economies against the price volatility of raw materials (2). The investment decisions, which have to been taken in the next 5 to 10 years, will determine the electricity production portfolio in the European Union for the next 50 years: 1. Around 800-900 GWe capacity will be required by 2030 to replace the existing capacity and to address increasing demand. 2. More than 50 % of the electricity in 2030 will be generated in plants have not been build today. 3. A total of 57.6 GWe of new nuclear power plants are projected to be commissioned between 2000 and 2030 (3). Only 9.4 GW of these are already certain investments. To ensure sustainable investment decisions, there needs to be reliable and effective framework conditions with the underlying principles: - competition among vendors; - efficient licensing; - solvent capital markets; - political framework; and - public acceptance. With regard to public acceptance, the Commission launched, based on the results of the EU summit in 2007, a platform for a broad stakeholder discussion about risks, challenges and opportunities of nuclear energy, the European Nuclear Energy Forum (ENEF). E.ON is actively involved in both discussion during the annual ENEF-summit and the working group sessions throughout the year. We appreciate these discussion and we face up the pros and

    The objective of this study is to assess the influencing factors of energy poverty in rural Cameroon. The method used is in two stages: the first stage is a statistical analysis that has allowed to determine the level of energy poverty in rural areas, which is 7.5%. The second stage assesses the influencing factors of this poverty type. The results show that the revenue impacts on energy poverty, as well as the size of the household, in which the arrival of an additional person increases by 1.16% the chances that the household will suffer from energy poverty. [French] L'objectif de cette etude est d'evaluer les determinants de la pauvrete energetique en milieu rural au Cameroun. La methode mise en oeuvre procede en deux etapes : la premiere est une analyse statistique qui a permis de determiner le seuil de pauvrete energetique en milieu rural, qui se situe a 7,5%. La deuxieme etape evalue les determinants de ce type de pauvrete. Les resultats indiquent que le revenu explique la pauvrete energetique, de meme que la taille du menage dont l'arrivee d'une personne supplementaire accroit de 1,16% les chances de ce menage d'etre pauvre sur le plan energetique.

    The paper presents some thoughts on several factors related to nuclear energy and the way they are presented by the mass media, usually provoking controversy to the Spanish society and thus, undermining public acceptance. Some possibilities for boosting nuclear energy among public opinion are suggested, emphasizing the fact that nuclear power is essential because it is both ecologically and economically sound.

    Clean energies such as nuclear and solar are part of the solution to the energy dependence that we face today and also help us to reduce the greenhouse gas emissions, thus avoiding a global average temperature increase that is irreversible and harmful to all living beings on the planet. Independently the nuclear and solar energies have had a great development in recent years, so in this work we set ourselves the task of creating a synergy between them. First, we conducted a survey of different people involved in the area of energy (energy efficiency, clean energy and renewable sources) in order to know if the area of which they are part influences with respect to the impression that they have of safety in terms of supply, return on investment and safety to the health and environment of another energy source for which we use a correlation analysis. With the results obtained we propose to use photo thermic solar energy as a support to reduce the frequency of accidents by station blackout and we perform the analysis of the combination using the methodology of Probabilistic Analysis of Security with the help of SAPHIRE 7 software to realize the event trees by station blackout of a nuclear power plant and faults for a photo-thermal solar plant. Finally, the decrease in the probability of station blackout from the proposed combination is quantified. The results were favorable to indicate that the probability of station blackout is reduced in half and that is why is suggested to continue studying the combination. (Author)

    Nuclear energy development in Japan has passed about 30 years, and reaches to a step to supply about 35 % of total electric power demand. However, together with globalization of economic and technical development, its future progressing method is required for its new efforts. Among such conditions, when considering a state of future type nuclear energy application, its contribution to further environmental conservation and international cooperation is essential, and it is required for adoption to such requirement how it is made an energy source with excellent economics.The Research Committee on 'Engineering Design on Nuclear Energy Systems' established under recognition in 1998 has been carried out some discussions on present and future status of nuclear energy development. And so forth under participation of outer specialists. Here were summarized on two year's committee actions containing them and viewpoints of nuclear industries, popularization of nuclear system technology, and so forth. (G.K.)

    Following the industry expansion, the energy consumptions have increased steeply, which have produced the global warming in our lives by carbon production energies. This climate change has provoked significant natural disasters which have damaged to social as well economic matters. Considering the non-carbon production which is the major factor of global warming, nuclear energy is a newly spotlighted source as the green energy source. The climate change factor is affected by the carbon productions made by humans. Then, the nuclear energy increasing rate with the climate change factor affects to the temperature change which is expressed by annual anomaly. Fig. 6 is the protocol for climate change investigation incorporated with the nuclear industry where the climate factor like the temperature is an important index to find out the priority of nuclear energy. The increased environmental pollutions can give the expanding of nuclear energy due to the carbon gas of fossil fuels. This study showed the effectiveness of the nuclear energy by the simulations. The seasonal climate disaster like the very cold winter and very hot summer can increase the necessity of nuclear energy development which could appeal to the general public persons as well as the politicians. So, it is important for the nuclear energy manager to make people understand the importance of the nuclear energy comparing to the oil or coal fuels. The regeneration energy has been considered as the alternative source.

    This article was newly written for useful discussion on energy policy based on the lecture at the Japan Science Council symposium 'How to amend energy policy after the Fukushima nuclear accident' held in July 2012. Basic standpoints of energy policy and positioning of nuclear power according to the 2010 energy basic program were reviewed. Nuclear power capacity was expected to increase from 49.5 GWe in 2007 to 68 GWe in 2030 to assure energy security. The accident forced energy policy to be amended starting with nuclear power zero base. The accident actualized the safety risks of nuclear power utilization, which were discussed from fragilities of three areas: (1) design basis, (2) emergency preparedness/response and (3) regulation system. Concrete measures to reduce risks of nuclear disaster were proposed. Role and responsibility of scientists was commented. Trend of energy policy based on basic philosophy selection for three scenarios in 2030 at the lecture time was confirmed and significance of nuclear power utilization was summarized from many-sided view points.

    The Government's Nuclear Review has given the nuclear industry an opportunity to demonstrate the key role that it can play in developing the UK's energy supply. To fulfil its ultimate potential in both the UK and international markets, nuclear energy must be able to compete in an open market alongside UK fossil fuel based suppliers and with overseas power generators. There are huge potential export opportunities for the nuclear industry, but for the UK to be able to compete in these markets there must be a thriving nuclear sector at home. The Government is now in a position to determine the future development of the nuclear energy industry. A positive commitment to nuclear power will not only be good for the nuclear industry, it will be good for the nation as a whole. (Author)

    There are still many problems in the field of measurement and control of neutron flux. The present studies in connexion with high flux reactors contribute to the solution of these problems which concern specialists in reactor control. The present state of this investigation and the results of different studies carried out in France by the C A and the EDF are pointed out: A - In the nuclear instrumentation field, work is at present devoted to the technologies used to develop detectors and cables, which have to work at high temperature and in a high {gamma} background; fast electronic techniques are applied to fission counters to measure low neutron fluxes in a high {gamma} background (10 Rh). B - In the control and safety field, there is a real need for studies on the behaviour of reactors in the subcritical state. This increases the margin of security during restarts when poison effects must be overcome The perturbations due to control rod movements necessitate a new organisation of power level safety and control assemblies, in connexion with thermal or activation measurements. Two methods of fast start-up are described. They are related to the fission rate measurement as a function of time. This is done either continuously by a constant and high reactivity change, or step by step. The application of automatic techniques to detector motion seems to give the answer to control and safety in normal start-up. C - The scope of these studies covers the methods used for the control of E.D.F. 3, which are described.

  18. Nuclear power: tomorrow's energy source

    International Nuclear Information System (INIS)

    2002-01-01

    In France, 76% of electricity is produced by nuclear power. The industry's pricing levels are among the most competitive in Europe. Thanks to its 58 nuclear reactors France enjoys almost 50% energy autonomy thus ensuring a highly stable supply. Equally, as a non-producer of greenhouse gases, the nuclear sector can rightfully claim to have an environmentally friendly impact. Against a background to increasing global demand with predictions that fossil fuels will run out and global warming a central issue, it is important to use production methods which face up to problems of this nature. There is no question that nuclear energy has a vital role to play alongside other energy sources. (authors)

    The Federal Republic of Germany holds position five on the list of the world's biggest energy consumers. This alone is a fact that puts special emphasis on the public discussion about the peaceful use of nuclear energy, in addition to the current events such as incidents and accidents in nuclear installations. A sober review of the pros and cons of nuclear energy for power generation has to take into account the economic effects and the costs to be borne by the national economy as a result of immediate abandonment of nuclear energy. The article in hand discusses chances, problems, and alternatives to nuclear energy (solar energy and wind power). (orig.) [de

    Women in Nuclear-Korea (WINK) surveyed the public understanding on various energy resources in early September 2006 to offer the result for establishment of the nuclear communication policy. The reason why this survey includes other energy resources is because the previous works are only limited on nuclear energy, and also aimed to know the public's opinion on the present communication skill of nuclear energy for the public understanding. The present study is purposed of having data how public understands nuclear energy compared to other energies, such as fossil fuels, hydro power, and other sustainable energies. The data obtained from this survey have shown different results according to the responded group; age, gender, residential area, etc. Responded numbers are more than 2,000 of general public and university students. The survey result shows that nuclear understanding is more negative in women than in men, and is more negative in young than older age

    The NRV (nuclear reactions video) is an open and permanently extended global system of management and graphical representation of nuclear data and video-graphic computer simulation of low energy nuclear dynamics. It consists of a complete and renewed nuclear database and well known theoretical models of low energy nuclear reactions altogether forming the 'low energy nuclear knowledge base'. The NRV solves two main problems: 1) fast and visualized obtaining and processing experimental data on nuclear structure and nuclear reactions; 2) possibility for any inexperienced user to analyze experimental data within reliable commonly used models of nuclear dynamics. The system is based on the realization of the following principal things: the net and code compatibility with the main existing nuclear databases; maximal simplicity in handling: extended menu, friendly graphical interface, hypertext description of the models, and so on; maximal visualization of input data, dynamics of studied processes and final results by means of real three-dimensional images, plots, tables and formulas and a three-dimensional animation. All the codes are composed as the real Windows applications and work under Windows 95/NT

    Europe is one of the world leaders in nuclear technology advancement. The development of spent fuel reprocessing is but one example of this. This process continues today with the development by France and Germany of the European Pressurised-Water Reactor. Nuclear research and development work is continuing in Europe, and must be continued in the future, if Europe is to retain its world leadership position in the technological field and on the commercial front. If we look at the benefits, which nuclear energy has to offer, in economic and environmental terms, 1 support the view that nuclear is an energy source whose time has come again. This is not some fanciful notion or wishful thinking. There is clear evidence of greater long-term reliance on nuclear energy. Perhaps we do not see new nuclear plants springing up in Europe, but we do see ambitious nuclear power development programmes underway in places like China, Japan and Korea. Closer to home, Finland is seriously considering the construction of a new nuclear unit. Elsewhere, in Europe and the US, we see a growing trend towards nuclear plant life extension and plant upgrades geared towards higher production capacity. These are all signs that nuclear will be around for a long time to come and that nuclear will indeed have a future

    This publication first gives a presentation of a European colloquium on energy strategies between the nuclear risk and the greenhouse effect. Then dealing with the relationship between nuclear energy and nuclear proliferation, a contribution comments the relationship between the civil use of nuclear energy (notably for electricity production) and the use of nuclear materials for nuclear weapons (posture of the five nuclear States, development of the counter-proliferation policy, proliferating countries and actors, evolution of the political context after the fall of the USSR). The next article discusses the rooms to manoeuvre when defining energy strategies, notably with respect to nuclear energy. It also outlines the challenge of energy efficiency improvement in France, particularly for electricity uses, and by limiting the road traffic dramatic increase.

    The development of human civilization in general as well as that of every country in particular is in direct relation to the assurance of a cost effective energy balance encompassing all industrial spheres and everyday activities. Unfortunately, the uncontrolled utilization of Earth's energy resources is already causing irreversible damage to various components of the eco-system of the Earth. Nuclear energy used for electricity and hydrogen production has the biggest technological potential for solving of the main energy outstanding issues of the new century: increasing of energy dependence; global warming. Because of good market position the political basis is assured for fast development of new generation nuclear reactors and fuel cycles which can satisfy vigorously increasing needs of affordable and clean energy. Political conditions are created for adequate participation of nuclear energy in the future global energy mix. They must give chance to the nuclear industry to take adequate part in the new energy generation capacity.(author)

  10. India's nuclear energy programme: prospects and challenges

    International Nuclear Information System (INIS)

    2011-01-01

    India has announced ambitious plans to expand its nuclear energy programme nearly 15 fold in the next 20 years, from the current 4,500 MWe to about 62,000 MWe by 2032. By 2020, India's Department of Atomic Energy (DAE) plans to install 20,000 MWe of nuclear power generation capacity (the fifth largest in the world). The department has plans beyond 2030 too. According to these plans India will have the capacity to produce 275 GWe (Giga Watt of electricity) of nuclear power by the year 2052. The DAE's projections are summarised. This is a truly ambitious plan. Without sufficient quantities of energy, India cannot hope to become a global power. Its dream of registering eight to nine per cent economic growth per annum will remain just that, a dream. Even with such ambitious plans on the nuclear energy front, the share of nuclear power in the overall energy mix will remain small. Currently nuclear energy constitutes only about three per cent of the total energy consumed in India. If the current projections are realised, the share of nuclear energy in the total energy output will still be about 20 per cent. India takes pride in its nuclear programme. Over the years, successive governments have fully supported the DAE's plans. This support is likely to continue in the future. In fact, following the Indo-US civil nuclear deal and the Nuclear Suppliers Group (NSG) waiver in 2008, the mood in India has turned upbeat. India is now getting integrated into the global nuclear regime even though it has not signed the Nuclear Non Proliferation Treaty (NNPT). The NSG waiver has, however, allowed India to enter into civil nuclear cooperation with several countries

    The energy situation in Europe is mainly characterized by a growth in consumption, together with increasing import dependence in all energy resources. Assuring security of energy supply is a major goal at European Union level, and this can best be achieved by an adequate energy mix, including nuclear energy, producing now 32 % of our electricity. An increase of this proportion would not only improve our independence, but also reduce greenhouse gases emissions in Europe. Another major incentive in favor of nuclear is its competitiveness, as compared to other energy sources, and above all the low dependence of the electricity price on variation of the price of the raw material. The European Commission has launched a series of initiatives aiming at better coordinating energy policies and research. Particular emphasis in future European research will be given on the long-term sustainability of nuclear energy through the development of fast reactors, and to potential industrial heat applications.

    Nuclear partisans and opponents have been fighting for years. On one side, the energy autonomy of France, its electricity exports and the 70000 people employed in the nuclear industry are put forward. On the other side, the accident risk, the cost and dangerousness of waste management are the key words. But, can France, like Germany, really phase out nuclear energy? Is there other solutions? Since the Fukushima accident, what has changed in the pro-nuclear discourse? How strong is the nuclear lobby in France? Can we really have an unbiased debate on this question? The author analyzes the global question of nuclear energy, both in France and abroad, without partiality and political ideology

  13. Alternatives to nuclear energy

    International Nuclear Information System (INIS)

    Terrado, E.N.

    1981-01-01

    This article discusses several possibilities as alternatives to nuclear energy and their relevance to the Philippine case. The major present and future fuel alternatives to petroleum and nuclear energy are coal, geothermal heat, solar energy and hydrogen, the first two of which are being used. Different conversion technologies are also discussed for large scale electricity production namely solar thermal electric conversion (STC), photovoltaic electric power system (PEPS) and ocean thermal energy conversion (OTEC). Major environmental considerations affect the choice of energy sources and technologies. We have the problem of long term accumulation of radioactive waste in the case of nuclear energy; in geothermal and fossil-fuels carbon dioxide uranium and accumulation may cause disastrous consequences. With regard to Philippine option, the greatest considerations in selecting alternative energy options would be resources availability - both energy and financial and technology status. For the country's energy plan, coal and geothermal energy are expected to play a significant role. The country's coal resources are 1.4 billion metric tons. For geothermal energy, 25 volcanic centers were identified and has a potential equivalent to 2.5 x 10 6 million barrels of oil. Solar energy if harnessed, being in the sunbelt, averaging some 2000 hours a year could be an energy source. The present dilemma of the policy maker is whether national resources are better spent on large scale urban-based energy projects or whether those should be focused on small scale, rural oriented installations which produced benefits to the more numerous and poorer members of the population.

    Since the release in 2010 of Technology Road-map: Nuclear Energy (IEA/NEA, 2010), a number of events have had a significant impact on the global energy sector and on the outlook for nuclear energy. They include the Fukushima Daiichi nuclear power plant (NPP) accident in March 2011, the global financial and economic crises that hit many industrialised countries during the period 2008-10 and failings in both electricity and CO 2 markets. Despite these additional challenges, nuclear energy still remains a proven low-carbon source of base-load electricity, and many countries have reaffirmed the importance of nuclear energy within their countries' energy strategies. To achieve the goal of limiting global temperature increases to just 2 deg. C by the end of the century, a halving of global energy-related emissions by 2050 will be needed. A wide range of low-carbon energy technologies will be needed to support this transition, including nuclear energy. This edition of the nuclear road-map prepared jointly by the IEA and NEA take into account recent challenges facing the development of this technology. The 2015 edition of the Nuclear Energy Technology Road-map aims to: Outline the current status of nuclear technology development and the need for additional R and D to address increased safety requirements and improved economics. Provide an updated vision of the role that nuclear energy could play in a low-carbon energy system, taking into account changes in nuclear policy in various countries, as well as the current economics of nuclear and other low-carbon electricity technologies. Identify barriers and actions needed to accelerate the development of nuclear technologies to meet the Road-map vision. Share lessons learnt and good practices in nuclear safety and regulation, front- and back-end fuel cycle practices, construction, decommissioning, financing, training, capacity building and communication. Key findings: Nuclear power is the largest source of low

    The primary energy demand of Germany currently is met to more than 50 per cent by imports of crude oil, natural gas and coal, with crude oil imports representing by far the largest quota, due to minor inland resources. Nuclear power is the energy source that reduces the country's dependence on imports, so that, also thanks to the nuclear energy source, oil consumption in Germany could be cut back to half in the years from 1970 until 1995. Although nuclear fuels have to be imported, too, uranium resources are plenty, and fuel supplies in the nuclear fuel cycle are guaranteed, so that this energy source can be considered as a quasi inland energy source.

    2006-01-01

    There are serious warnings about depletion of oil and gas and even more serious warnings about dangers of climate change caused by emission of carbon dioxide. Should developed countries be called to replace CO2 emitting energy sources as soon as possible, and the time available may not be longer then few decades, can nuclear energy answer the call and what are the requirements? Assuming optimistic contribution of renewable energy sources, can nuclear energy expand to several times present level in order to replace large part of fossil fuels use? Paper considers intermediate and long-term requirements. Future of nuclear power depends on satisfactory answers on several questions. First group of questions are those important for near and intermediate future. They deal with economics and safety of nuclear power stations in the first place. On the same time scale a generally accepted concept for radioactive waste disposal is also required. All these issues are in the focus of present research and development. Safer and more economical reactors are targets of international efforts in Generation IV and INPRO projects, but aiming further ahead these innovative projects are also addressing issues such as waste reduction and proliferation resistance. However, even assuming successful technical development of these projects, and there is no reason to doubt it, long term and large-scale nuclear power use is thereby not yet secured. If nuclear power is to play an essential role in the long-term future energy production and in reduction of CO2 emission, than several additional questions must be replied. These questions will deal with long-term nuclear fuel sufficiency, with necessary contribution of nuclear power in sectors of transport and industrial processes and with nuclear proliferation safety. This last issue is more political then technical, thus sometimes neglected by nuclear engineers, yet it will have essential role for the long-term prospects of nuclear power. The

    For decades the peaceful use of nuclear energy has been regarded as a blessing, the military use, however, as a curse. The scepticism, however, whether this principal difference is justified has increased with the criticism of nuclear energy. Can the one who disposes of nuclear power plants also build nuclear bombs. These questions are posed by Amory Lovins (Soft Energy) and his wife in this work. Against this background the world-wide export of nuclear reactors gains a special explosive effect. The exporters, among them also the Federal Republic of Germany, claim that the military use of the nuclear know-how can be stopped by controls. Reality looks quite different. The authors show that the plutonium being produced in the reactor can be used for military purpose without any big technical efforts and that an effective control of this military use does not exist. On the contrary: nuclear reactors may be the welcome civilian cloak for the production of nuclear bombs. The hard energy-political way which is oriented towards nuclear energy increases the military destruction potential and thus threatens the world peace. To-day, as only one bomb has the total explosive force being used during the Second World War more and more people are of the conviction: we all will explode, the question is only - when.

    Nuclear power has experienced a major boom in the last few years, primarily because it is a non-CO{sub 2} emitting energy source, it can be produced at competitive costs and it can boost a country's security of supply. there are still two issues to be addressed in relation to the currently used technologies: the degree to which the energy content of nuclear fuel is used, and wastes. A solution to both these aspects would ut nuclear power in the category of sustainable energy. The article provides details on current nuclear plans in the wold, the impact of the Fukushima accident on different countries nuclear plans and the European initiatives for sustainable nuclear energy development.

    In the first part are studied the general relationships between the physical effects produced by neutrons in solids, and the total flux and neutron energy spectrum; some examples are given. The second part, describes the application to a silicon damage detector whose principle is to use the damage produced in a PIN Junction for measuring the neutron flux (intermediate and fast) received by the detector. Chapter I is devoted to the experimental determination of the energy given to the atoms by a primary in the silicon. The results and conclusions drawn from this determination make it possible to consider, in chapter II, the calculation of the detectors response characteristics.Chapter III deals with the measurement of the detectors response function and it is noted that good agreement is obtained between the calculation and experimental results. The whole of the second part constitutes a test of the methods presented in the first part. (author) [French] Dans la premiere partie, nous etudions les relations generales qui lient les effets physiques engendres par les neutrons dans les solides au flux integre et au spectre des neutrons et nous donnons des exemples d'utilisation.

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

    Nuclear energy may play a significant role in a future sustainable energy mix. The transition from today's nuclear energy system towards a future more sustainable nuclear energy system will be dictated by technology availability, energy market competitiveness and capability to achieve sustainability through the nuclear fuel cycle. Various scenarios have been investigated worldwide each with a diverse set of assumptions on the timing and characteristics of new nuclear energy systems. Scenario-based roadmapping combines the dynamic scenario-analysis of nuclear energy systems' futures with the technology roadmap information published and analysed in various technology assessment reports though integrated within the nuclear technology roadmap Nuclear-Roadmap.net. The advantages of this combination is to allow mutual improvement of scenario analysis and nuclear technology roadmapping providing a higher degree of confidence in the assessment of nuclear energy system futures. This paper provides a description of scenario-based roadmapping based on DANESS and Nuclear-Roadmap.net. (author)

    As nuclear community sometimes feel desperate because the nuclear energy is a very special subject triggering so much controversy among women and young persons especially it has been found that the battle against nuclear energy is just a pretext. Comparing the campaign on a referendum against hydropower - voted in Switzerland in may 1992 it was found astonishingly that exactly the same arguments were applied as during the campaign for the phase out of nuclear energy in 1990. The results were presented at PIME 1991. Voting behaviour for nuclear energy and hydro power are comparable: the gender gap (32% acceptance by men versus 48% by women) found in the 1992 vote about stopping hydropower plants in Switzerland was bigger than the one found in the 1990 vote about nuclear energy. A detailed analysis of these data is presented

    The energy supply optimization model MESSAGE-III is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Emphasis is placed on the potential contribution of nuclear energy in case of environmental constraints and energy resource limitation. The time horizon is 1993-2040. A program to forecast useful energy demand is developed, and optimization is performed from the overall energy system to the nuclear energy system. Reactor and fuel cycle strategy and the expanded utilization options for nuclear energy system are suggested. FBRs, HTGRs and thorium fuel cycle would play key roles in the long run. The most important factors for nuclear energy in Korean energy supply strategy would be the availability of fossil fuels, CO 2 reduction regulation, and the supply capability of nuclear energy.

    What contribution can nuclear energy make to improve the security of energy supply? This study, which examines a selection of OECD member countries, qualitatively and quantitatively validates the often intuitive assumption that, as a largely domestic source of electricity with stable costs and no greenhouse gas emissions during production, nuclear energy can make a positive contribution. Following an analysis of the meaning and context of security of supply, the study uses transparent and policy-relevant indicators to show that, together with improvements in energy efficiency, nuclear energy has indeed contributed significantly to enhanced energy supply security in OECD countries over the past 40 years. Content: Foreword; Executive Summary; 1. The Security of Energy Supply and the Contribution of Nuclear Energy - Concepts and Issues: - Energy supply security: An introduction, - Why security of energy supply remains a policy issue in OECD countries, - The external dimension: import dependence, resource exhaustion and carbon policy, - The internal dimension: economic, financial and technical considerations for energy supply security - Orientations for government policies to enhance the security of energy supply, - Conclusions; 2.

    Moncomble, J.E.

    2002-01-01

    This article is the work of a group of students from the ''Ecole Nationale d'Administration'', they had to study the perspective of nuclear energy in France. Nuclear energy is an important element to assure the stability of the energy supply of the country. Uranium purchases appear to be safe for being diversified and the price of the nuclear fuel contributes to only 20% of the price of the kWh compared to 40% for natural gas. Today the competitiveness of nuclear energy is assured but technological progress concerning gas turbines might challenge it in the years to come. Sustainable development implies not only abundant energy for all but also a preserved environment for the generations to come. The development of nuclear energy is hampered by the lack of satisfactory answers to the problem of fuel back-end cycle and more generally to the issue of radioactive wastes. On the other hand nuclear energy presents serious assets concerning the preservation of environment: nuclear energy as a whole from the uranium ore mining to the production of electricity emits very few atmospheric pollutants and greenhouse effect gases, and requires little room for its installations. The composition of the future energy mix will depend greatly on opinions and assumptions made about the reserves of fossil fuels, technological perspectives and the perception by the public of industrial risks (environmental damage, nuclear accidents...).

    The third update of the Federal Government's energy programme refers to the subject nuclear energy only with the idea that for energy and industrial political reasons nuclear energy should make a further increasing contribution to power generation in the field of base load. It is true, the annex contains - in form of an abstract - the results of a study of the three energy-economic Institutes which also contain some precise data on the necessary expansion of the Atomic Energy Act. The wording of the update report, however, clearly says that the Federal Government does not adopt the forecastings of the Institutes especially those for the capacity of nuclear power plants considered to be necessary by 1995 (37 000 to 39 500 MW). So, for a number of comprehensible reasons, the Federal Government consciously rejects a nuclear power plant programme such as Government and Parliament have recently decided on in France. Just for this reason, it seems to be reasonable to consider carefully which data and facts have to be taken into account with such a programme and to which results such a - let's say experimental - evaluation could lead. This is the purpose of this contribution. (orig.) [de

    Nuclear energy for electricity generation will extend its market portion in Europe in the coming decades because: 1) its economic and/or environment-relevant advantages compared with the fossil energy sources are so explicit that the latter will no longer be competitive; 2) the improvements of the system engineering, which are presently being implemented and are to be expected in the future, will enhance the safety facilities to the extent that accident risk will cease to be a decisive factor; 3) energy-saving effects or the use of solar energy will not provide an appropriate large scale alternative for coal and/or nuclear energy; 4) the problems of radioactive waste disposal will be definitely solved within the foreseeable future. Considering all the technological systems available the light water reactor will continue to dominate. The change to the breeder reactor is not yet under discussion because of the medium-term guaranteed uranium supply. The use of nuclear technology in the heating market will depend for the moment on the availability and cost of oil and gas development. In principle nuclear energy can play an important role also in this sector

    2006-01-01

    The United States has embraced nuclear as an important component of its energy future. Triggered by successful passage of the Energy Policy Act in November 2005, four federal initiatives are enjoying some measure of initial success. The first energy authorization act in 13 years, the new legislation contains incentives for up to six new nuclear plants comparable to those for other clean energy sources. Once these incentives were codified, US utilities began to express interest in expanding the nuclear fleet. The Department of Energy's (DOE) push for new nuclear plants, called the 2010 Initiative, has been underway since 2002. Prior to last November, the Nuclear Regulatory Commission (NRC) had no official expressions of interest in building new nuclear plants. Since November, the NRC has been notified of interest in building at least 26 new advanced light water reactors, concentrated at existing nuclear sites in the rapidly growing Southeastern United States. In addition, most of the 103 currently operating plants are expected to obtain 20 year life extensions. Utilities, suppliers and the regulator have been increasing their staffs in anticipation of the new plant orders. Undergraduate nuclear engineering enrollment has surged to its highest level in more than 15 years. The Department of Energy is also moving ahead with its licensing application for a geologic repository at Yucca Mountain. Because exiting legislation limits the amount of spent fuel and nuclear waste that could be stored in the mountain, Congress, DOE and the nuclear industry have become interested in alternative management schemes for the repository. The major DOE initiative is the Global Nuclear Energy Partnership (GNEP), which would close the fuel cycle and introduce advanced fast reactors to manage the long-lived actinides. GNEP also has a major international component, with partnerships to provide reliable fuel supply worldwide to any nation with valid nonproliferation credentials. The United

    Meeting the growing demand for energy, and electricity in particular, while addressing the need to curb greenhouse gas emissions and to ensure security of energy supply, is one of the most difficult challenges facing the world's economies. No single technology can respond to this challenge, and the solution which policy-makers are seeking lies in the diversification of energy sources. Although nuclear energy currently provides over 20% of electricity in the OECD area and does not emit any carbon dioxide during production, it continues to be seen by many as a controversial technology. Public concern remains over its safety and the management of radioactive waste, and financing such a capital-intensive technology is a complex issue. The role that nuclear power will play in the future depends on the answers to these questions, several of which are provided in this up-to-date review of the status of nuclear energy, as well as on the outcome of research and development on the nuclear fuel cycle and reactor technologies

  1. Long-term cost targets for nuclear energy

    2004-01-01

    In 2000 the International Atomic Energy Agency (IAEA) began the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) to help guide nuclear R and D strategies targeted on anticipated mid-century energy system needs. One part of INPRO seeks to develop cost targets for new designs to be competitive in mid-century markets. The starting point was the 40 scenarios of the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change. This paper summarizes four of the SRES scenarios, one from each of the four SRES scenario families. It discusses their implications for nuclear energy, including cost targets, and develops for each an 'aggressive nuclear' variant. The aggressive nuclear variants estimate the potential market for nuclear energy if, by improving faster than assumed by the SRES authors, nuclear energy can make inroads into vulnerable market shares projected for its competitors. In addition to projected demands for nuclear generated electricity, hydrogen and heat, the aggressive variants include prospective demand for nuclear desalination and use in upgrading fossil fuels. The paper then presents learning rates and implied cost targets consistent with the aggressive nuclear variants of the SRES scenarios. One provocative initial result is that many of the scenarios with substantial nuclear expansion do not seem to require big reductions in nuclear investment costs. One interpretation discussed at the end of the paper highlights the difference between cost reductions consistent with long-term energy system optimization based on perfect foresight, and cost reductions necessary to attract private investment in today's 'deregulating' and uncertain energy markets.

    The information tells us that since the first chain reaction discovery about 50 years ago up to now, there are more than 400 commercial nuclear power plants connected to electricity supply net works. The electricity supplied by nuclear power plants has exceeded 2000 TWH, which represents almost 17% of the total electricity generated in the world and this proportion is still increasing. The accumulated operating experience of nuclear power plants reach more than 6000 reactor-year. Quite high average life time energy availability factors demonstrate the good reliability of nuclear power plants. The present status of the electricity development in the world shows that nuclear power has become an imperative and exclusively realistic alternative energy source. All of these information demonstrate that nuclear power as a safe, clean and less cost power source has already been widely accepted in the world. In Asia and Pacific region, the fast development of economy provides a vast possibility for the development of nuclear power. In China, shortage of electricity has become the 'bottle neck' which retards the economic development nowadays. China has already drawn up the plan for the development of nuclear power. The information is of great significance to promote the development of nuclear power. It could be said that without information, nuclear power could not be smoothly introduced in any country or region. (J.P.N.)

    Starting from the actual position in the electricity market nuclear energy will grow up to the stabilizing factor in this field. The market penetration of breeding and fusion systems, therefore, will be the next important milestones of nuclear energy development. On the other hand nuclear energy as well as the electric grid itself are good examples for the reconstruction of the non-electric energy market which is dominated by resource and environmental problems. To overcome these problems the installation of a refining step for fossil energy resources and a new transport system besides the electric grid are the next steps toward a crisis-proof energy supply system.

    Full Text Available Nuclear power in its present form was created during the Cold War and is its heritage. The main objective of nuclear energy at that time, along with energy, was the creation and accumulation of nuclear materials. To this aim a existing nuclear power plants based on uranium-plutonium cycle. Everything else - the processing of radioactive waste and spent nuclear fuel, storage, recycling themselves nuclear power plant after its end of life, the risks of proliferation of nuclear materials and other environmental issues - minor. It was also believed that the nuclear power plant - the most reliable and safe plant. During the last twenty years all over the world the number of new orders for nuclear aggregates has decreased. That happens for a number of reasons, including public resistance, that the construction of new NPP and the excess of energy utilities in many markets, which is mainly connected with high market competition in energy markets and low economic indicators of the current nuclear utilities. The technology that consists of low capital costs, a possibility for quick construction and guarantied exploitation quality is on the winners side, but currently this technology is absent. However, despite abovementioned downsides, as the experience of state corporation "Rosatom"has shown, many developing countries of the South-east Asia, The middle East, African regions express high interest in the development of nuclear energy in their countries. The decision whether to develop nuclear energy or to continue to develop is, in the end, up to the choice of the tasks that a country faces. The article describes these "minor" issues, as well as geopolitical and economic problems of the further development of nuclear energy.

  13. Nuclear energy in France. Which usefulness? Which future?

    International Nuclear Information System (INIS)

    Sorin, Francis

    2014-01-01

    After having recalled the main objectives of the French policy on energy transition (energy efficiency, energy saving, development of renewable energies) and evoked the controversy about the decrease of the nuclear share in the French energy mix, the author recalls the context of development of nuclear energy in France which aimed to ensure an independent electricity supply. Then, the author outlines the benefits of this independence in terms of economy, industrial development and protection of the environment. He discusses the perspectives and challenges of nuclear energy and industry in France with respect to energy transition, to the possibility of life extension for the French nuclear fleet, to the improvement of safety after the complementary safety assessments performed after Fukushima, to the EPR design and to the development of new generations (III and IV) of nuclear reactors, and to new applications of nuclear energy (desalination, transports, district heating). In a last part, the author discusses the perspective of development of nuclear energy in the world

    This report takes stock on the nuclear energy situation in Europe. The European Union with more than 40% of the nuclear power capacity in the world, is already confronted with the nuclear energy place and stakes in the future energy policy. The report si presented in two main parts. The first part, ''the assets and the weaknesses of the nuclear energy'', deals with the economical aspects which historically based the choice of the nuclear energy and the induced impacts on the environment. The competitiveness of the nuclear energy but also the wastes management problem are discussed. The second part, ''the diplomatic and juridical framework of the nuclear energy development'', details and presents the limits of the EURATOM treaty. (A.L.B.)

  15. Whither the legal control of nuclear energy?

    International Nuclear Information System (INIS)

    Riley, Peter

    1995-01-01

    International nuclear trade is governed by the regime of legal control of nuclear energy, nuclear materials, knowledge of nuclear processes and weapons. Nuclear trade is under pinned by international agreements concerning physical protection and safeguards, the control of nuclear weapons, the protection of nuclear materials from terrorist action and third part liability. The political and geographical boundary changes of the past two years have significantly altered the background against which this regime has developed. Such changes have affected nuclear trade. The paper summarised the legal control of nuclear energy between States, identifies the areas of change which may affect this regime and the consequences for international trade. Conclusions are drawn as to the development of the international legal control of nuclear energy. (author). 21 refs

  16. Low Energy Nuclear Reactions: 2007 Update

    Science.gov (United States)

    Krivit, Steven B.

    2007-03-01

    This paper presents an overview of low energy nuclear reactions, a subset of the field of condensed matter nuclear science. Condensed matter nuclear science studies nuclear effects in and/or on condensed matter, including low energy nuclear reactions, an entirely new branch of science that gained widespread attention and notoriety beginning in 1989 with the announcement of a previously unrecognized source of energy by Martin Fleischmann and Stanley Pons that came to be known as cold fusion. Two branches of LENR are recognized. The first includes a set of reactions like those observed by Fleischmann and Pons that use palladium and deuterium and yield excess heat and helium-4. Numerous mechanisms have been proposed to explain these reactions, however there is no consensus for, or general acceptance of, any of the theories. The claim of fusion is still considered speculative and, as such, is not an ideal term for this work. The other branch is a wide assortment of nuclear reactions that may occur with either hydrogen or deuterium. Anomalous nuclear transmutations are reported that involve light as well as heavy elements. The significant questions that face this field of research are: 1) Are LENRs a genuine nuclear reaction? 2) If so, is there a release of excess energy? 3) If there is, is the energy release cost-effective?

    Weinberg, A.M.

    1984-01-01

    Nuclear energy is faltering in many places - especially in the USA: should it be written off. The author sees underlying trends that justify a more optimistic view of nuclear energy's future - the continuing tendency for the electricity intensity of economic activity to rise while the total energy intensity falls; a consistently favourable price trend for electricity compared with energy prices generally - a trend that may become more favourable if his judgment that nuclear plants will turn out to be very long-lived is borne out by events; the substitution of electricity-based processes in industry for older processes; and the development of ultra-safe reactors which will remove once and for all the fears of accidents such as the one that occurred at Three Mile Island.

    Tennenbaum, J.

    1994-01-01

    Amongst the important scientific and technological revolutions of history there is none in which women have played such a substantial and many-sided role as in the development of nuclear energy. The birth of nuclear energy is not only due to Marie Curie and Lise Meitner but also to a large number of courageous 'nuclear women' who decided against all sorts of prejudices and resistances in favour of a life in research. Therefore the revolution of the atom has also become the greatest breakthrough of women in natural sciences. This double revolution is the subject of this book. Here the history of nuclear energy itself is dealt with documented with the original work and personal memories of different persons - mainly women - who have been substantially involved in this development.

    The emphasis is put on communication processes, here in particular with regard to nuclear energy. Not so much dealt with are questions concerning political regulation, the constellation of power between those becoming active and risk perception by the population. Presented are individual arguments, political positions and decision-making processes. Dealt with in particular are safety philosophies, risk debates, and attempts to 'channel' all sides to the subject of nuclear energy. (DG) [de

    Nuclear energy is an important part of a balanced energy mix. Nuclear energy has the potential to make a significant contribution both to economic development and to a significant cost-effective reduction in carbon emissions, probably the two most salient aspects of sustainable development. Nuclear energy has clearly demonstrated its usefulness and favorable contribution in the past. Continuous development of nuclear technologies is warranted to achieve future sustainable development. Therefore, an open discussion on the potential future role of nuclear can be helpful to remove some political motivated constraints on nuclear power development. (author) 1 fig., 2 refs

    On the basis of experimental results selected from publications, the evolution of the bond energy of a molecular system under irradiation - leading to a more or less bound state - is studied. This variation of bond energy is then compared to the total bond energy of the initial system and to the energy absorbed in the system during the irradiation. This is done as a function of the nature of molecular system and the radiation spectrum and intensity. Our working method will first be explained, and the results obtained will then be given. (authors) [French] A l'aide de resultats experimentaux, selectionnes dans les publications, nous etudions l'evolution de l'energie de liaison d'un systeme moleculaire sous irradiation (evolution vers un etat plus ou moins lie), et nous comparons cette variation d'energie de liaison a l'energie totale de liaison du systeme initial et a l'energie absorbee dans le systeme au cours de l'irradiation. Ceci est fait en fonction de la nature du systeme moleculaire ainsi que du spectre et de l'intensite du rayonnement. Nous exposons d'abord notre methode de travail, puis les resultats obtenus.

  7. Effect of the Fukushima nuclear disaster on global public acceptance of nuclear energy

    International Nuclear Information System (INIS)

    Kim, Younghwan; Kim, Minki; Kim, Wonjoon

    2013-01-01

    The Fukushima nuclear disaster has significantly changed public attitudes toward nuclear energy. It is important to understand how this change has occurred in different countries before the global community revises existing nuclear policies. This study examines the effect of the Fukushima disaster on public acceptance of nuclear energy in 42 countries. We find that the operational experience of nuclear power generation which has significantly affected positive public opinion about nuclear energy became considerably negative after the disaster, suggesting fundamental changes in public acceptance regardless of the level of acceptance before the disaster. In addition, contrary to our expectation, the proportion of nuclear power generation is positively and significantly related to public acceptance of nuclear energy after the Fukushima accident and government pressure on media content led to a greater decrease in the level of public acceptance after the accident. Nuclear energy policymakers should consider the varied factors affecting public acceptance of nuclear energy in each country depending on its historical, environmental, and geographical circumstances before they revise nuclear policy in response to the Fukushima accident. - Highlights: • Fukushima accident has negatively changed public attitudes toward nuclear energy. • Effect of operational experience became considerably negative after the accident. • Effect of proportion of nuclear power generation is positive after the accident. • Effect of government pressure on media content became negative after the accident. • Country specific policy responses on nuclear public acceptance are required

  8. Future nuclear energy scenarios for Europe

    International Nuclear Information System (INIS)

    Roelofs, F.; Van Heek, A.

    2010-01-01

    Nuclear energy is back on the agenda worldwide. In order to prepare for the next decades and to set priorities in nuclear R and D and investment, market share scenarios are evaluated. This allows to identify the triggers which influence the market penetration of future nuclear reactor technologies. To this purpose, scenarios for a future nuclear reactor park in Europe have been analysed applying an integrated dynamic process modelling technique. Various market share scenarios for nuclear energy are derived including sub-variants with regard to the intra-nuclear options taken, e.g. introduction date of Gen-III (i.e. EPR) and Gen-IV (i.e. SCWR, HTR, FR) reactors, level of reprocessing, and so forth. The assessment was undertaken using the DANESS code which allows to provide a complete picture of mass-flow and economics of the various nuclear energy system scenarios. The analyses show that the future European nuclear park will exist of combinations of Gen-III and Gen-IV reactors. This mix will always consist of a set of reactor types each having its specific strengths. Furthermore, the analyses highlight the triggers influencing the choice between different nuclear energy deployment scenarios. In addition, a dynamic assessment is made with regard to manpower requirements for the construction of a future nuclear fleet in the different scenarios. (authors)

    In this work we will try to show that nuclear energy can contribute to the generation energy in the present and the future, considering that its effect on the climatic change is relatively low and that the fuels that uses are available a large scale. At the moment it is had already commercial thermal fission reactors , there are also them of fast fission that allow the fuel rearing, although these last ones in much smaller number, with both types of fission nuclear reactors can be obtained a very important contribution to the generation of energy at world-wide level during the time that is necessary so that it is developed, constructs and operates the first commercial fusion reactor. The energy that is generated in the present and future must come from different sources, which require to be reliable, to have little effect on the environment, to have wide reserves of fuels and to be viable from an economic and social point of view, they must be viable and safe. Between possible alternative energies it is counted on the lot, the wind one, the geothermal one, originating of the tides and some others. An energy that must be considered so that it has arrived at his maturity and he is already able to contribute widely to cover the present needs and future it is nuclear energy, as much the originating one of the fission of a heavy centre like obtained when fusing two light centers. On base in the nuclear fuel reserves at world-wide level a simple calculation takes control of the lapse in which energy by means of the nuclear fission in rearing can be generated reactors expresses demonstrating that the time sufficient to finish to the investigation and development of fusion reactors which they generate energy in economic, safe and reliable form. Combining these two options the nuclear energy can be considered the future like for the present and the future with practically null effects in the climatic change. (Author)

    Nuclear power is still an unknown subject to many and ends up being left out when it comes to alternative energy sources and environmental preservation. Unfamiliarity and the disclosures information that are not always correct end up not to show the public the true risks and benefits of this source. The strength of public opinion is the main barrier to the advancement of this technology. So, this paper aims to demystify the villain aspect of nuclear energy that could become a major source for power generation. For this, will be made a historical retrospective of the theories that enabled the field of nuclear fission, the authors and key points, such as will be described how nuclear fission reaction is produced, controlled and sustained and how energy is produced, will be also made an argument on key facts that lead public opinion to stand up against nuclear power, as the generation of radioactive waste and nuclear weapons. Are presented possible solutions beyond the learning and improvements resulting from the occurred accidents. After these analyzes was observed that, besides being a potentially clean source for power generation, it can be safe in order that the waste generated are already safely managed and intelligence groups also monitor terrorist groups, seeking to ensure global security in relation to nuclear weapons and, at the issue of accidents, each event has brought learning and became the nuclear industry today, one of the safest.

  13. Energy supply and nuclear energy

    International Nuclear Information System (INIS)

    Heitzer, H.

    1977-01-01

    The author emphasizes the necessity and importance of nuclear energy for the energy supply and stresses the point that it is extremely important to return to objective arguments instead of having emotional disputes. In this connection, it would be necessary for the ministries in question to have clear-cut political responsibility from which, under no circumstances, they may escape, and which they cannot pass on to the courts either. Within the framework of listing present problems, the author is concerned with the possibility of improved site planning, the introduction of a plan approval procedure and questions concerning immediately enforceable nuclear licences. He also deals with a proposal, repeatedly made, to improve nuclear licensing procedures on the one hand by introducing a project-free site-appointment procedure, and on the other hand by introducing a simplified licensing procedure for facilities of the same kind. Splitting the procedure into site and facility would make sense solely for the reason that in many cases the objections are, above all, directed against the site. (HP) [de

    Nuclear collisions are interpreted theoretically. The nuclear equation of state is studied in a wide energy range. Subnucleonic degrees of freedom are invoked at high energy densities and at short length-scales. Questions of dynamical collision simulations are investigated. Direct support is provided for experiment in the form of collaborative projects. The major objective of this nuclear theory program is a better understanding of the properties of strongly interacting matter on the nuclear energy scale, as manifested in high-energy heavy-ion collisions

    2014-06-01

    After having recalled the meaning of the concept of energy transition, and stated that this concept is a fuzzy one, this paper addresses the issue of the future of energy through the concept of Energy returned on Energy invested (EROI). It discusses this approach by outlining that energy is the initial driver of economy, and by showing that only hydroelectricity, coal, nuclear and wind energy have a sufficient return rate, and that shale gas is an energy source for the short and medium term. Then, based on data related to world energy resources and consumption, to electric power production from various sources, to pollution health impacts, to electricity prices for industries and for households, it discusses the sustainability of the energy mix regarding energy reserves, health issues, and economic issues. Some examples (Spain, Germany) illustrate economic problems faced by some renewable energies. Finally, the authors outline that, thanks to its nuclear policy, France is the western country which is the most committed in energy transition. Some proposals are made to support nuclear energy, to reduce the use of fossil energies, to launch an ambitious research policy (on energy storage, on photovoltaic energy, on CO 2 hydrogenation, on hydrogen as a fuel), in favour of energy mixes decided at national levels in Europe

    Nuclear energy appears to be a main asset to France in the context of the worldwide economic slump. Nuclear power provides a cheap electricity that spares the buying power of households and increases the competitiveness of French enterprises. Nuclear industry with major companies like EDF, AREVA and CEA and 450 small and medium-sized enterprises, represents a core resistant to industrial decline. Nuclear industry is a good provider of work and globally it represents 2% of all the jobs in France. Concerning the trade balance, nuclear power plays twice; first by exporting equipment and services for a value of 7 billions euros a year and secondly by sparing the cost of energy imports that would be necessary if nuclear power was not here which is estimated to 20 billions euros a year.

    India is facing great challenges in its economic development due to the impact on climate change. Energy is the important driver of economy. At present Indian energy sector is dominated by fossil fuel. Due to international pressure for green house gas reduction in atmosphere there is a need of clean energy supply for energy security and sustainable development. The nuclear energy is a sustainable solution in this context to overcome the environmental problem due to fossil fuel electricity generation. This paper examines the implications of penetration of nuclear energy in Indian power sector. Four scenarios, including base case scenario, have been developed using MARKAL energy modeling software for Indian power sector. The least-cost solution of energy mix has been measured. The result shows that more than 50% of the electricity market will be captured by nuclear energy in the year 2045. This ambitious goal can be expected to be achieved due to Indo-US nuclear deal. The advanced nuclear energy with conservation potential scenario shows that huge amounts of CO 2 can be reduced in the year 2045 with respect to the business as usual scenario.

  5. Regional and global significance of nuclear energy

    International Nuclear Information System (INIS)

    Schilling, H.D.

    1995-01-01

    Measures to combat poverty and improve the standard of living in countries of the Third World will inevitably boost global demand for energy, and energy conservation measures will not be able to offset this increase. Nuclear energy will regain significance in the framework of approaches adopted to resolve the energy problem, which primarily is an ecologic problem created by an extremely large flow of materials. The extraordinarily high energy density of nuclear fuels can contribute to markedly reduce the flow of materials; and at that, electric energy is an efficient substitute for primary energy forms. Thus nuclear electricity generation is of double benefit to the ecology. Engineering goals in nuclear technology thus gain a service aspect, with progress in power plant engineering and design aiming not only at enhanced engineered safety, but also at regaining public acceptance of and confidence in nuclear power plant technology.

    It examines the technical, scientific and legal issues relating to the peaceful use of atomic energy in Turkey. The first fifteen chapters give a general overview of the atom and radioactivity; the chapters which follow this section are more technical and deal with the causes of nuclear accidents in reactors.A number of chapters cover legal issues, for example the conditions and procedures involved in the insurance market and the risks linked to operation of a nuclear power plant.The following subjects are examined in relation to nuclear insurance: risks during construction; fire during operation of the plants and other causes of accidents; risks due to the transport of radioactive materials and waste etc. The final chapters reproduce the principle legislative texts in force in Turkey in the field of nuclear energy, and also certain regulations which establish competent regulatory bodies

    This debate is based on a study recently published by Ifri's Energy Program (Les relations franco-allemandes dans le secteur de l'energie, by Jan Horst Keppler, Sophie Meritet and Kristina Notz). Franco-German energy relations are often dominated by debates on nuclear power and, for many observers, the two countries seem far apart on this question. Indeed, very different political decisions have been made by either country on the issue. Surprisingly, opinion polls have shown that public opinion on nuclear energy is quite similar in both countries. Furthermore, the cooperation between Areva and Siemens in the nuclear field is one of the best examples of Franco-German industrial cooperation. In more general terms, France and Germany have a quite different energy mix and hence both countries have divergent positions concerning some aspects of European energy policy. Positions on nuclear energy phasing-out, electricity networks, energy security and gas supply, fuel substitution, climate change and the development of renewable energy sources, etc. are discussed

    The history of civilization is full of striking examples of nations which were not able to develop their technology either disappeared from the stage of the history or lost their independence and were forced to live under the domination of others. The major cause of the wars that caused the lives of millions of people in 20th century is, to possess the energy sources, which are the basis of social and economic development. Ataturk has shown a personal interest to energy issue saying t o be industrialized is a must for the development . The encouragement of industry act in 1927 stated t he most important priority of Turkey is the energy problem . For economic and social wealth, freeing the country from the dependency on other countries and solving the energy bottleneck, the Turkish media is to know the nuclear technology rather than being scared of it and realize that it is the integral part of the solution of the energy problem. In conclusion Turkey is to realize and do necessities of the nuclear era in order to catch a bright future. Due to these facts, this study aims to furnish the public with bare facts of nuclear energy and technology to eliminate the biased wiew regarding to nuclear technology

    Full text : The global demand for electricity is rapidly increasing. There is growing uncertainty in regard to the supply and prices of oil and natural gas. These considerations have opened new prospects for the development of nuclear energy on a global state. Despite the negative impact of the Fukushima Daichi accident, still some countries are considering or have expressed interest in developing nuclear power programmes. As the country using nuclear technology is primarily responsible for safety and as operational safety cannot be out sourced, building of sound safety expertise and strong safety culture is an essential precondition for the country introducing nuclear technology. Turkey's energy policy is naturally focused on the security, sustainability and competitiveness of energy supply. It is designed to sustain targeted economic and social growth in the long run. Turkey remains resolutely committed to the goal of ensuring safe, secure and peaceful utilization of nuclear energy

    1996-01-01

    The role of energy is indeed very important since without it there will be no living-things in this world. A country's ability to cultivate energy determines the levels of her civilization and wealth. Sufficient energy supply is needed for economic growth, industrialization, and modernization. In a modern civilization, the prosperity and security of a country depends more on the capability of her people rather than the wealth of her natural resources. Energy supplies the wealth, prosperity and security, and sufficient reliable continuous supply of energy secures the sustainable development. The energy supply to sustain the development has to improve the quality of life covering also the quality of environment to support the ever increasing demand of human race civilization. Energy has a closer relationship with civilization in a modern society and will have to become even closer in the future more civilized and more modern society. The utilization of nuclear energy has, however, some problems and challenges, e.g. misleading information and understanding which need serious efforts for public information, public relation, and public acceptance, and possible deviation of nuclear materials for non-peaceful uses which needs serious efforts for technological and administrative barriers, precaution, prevention, safety, physical protection, safeguard, and transparency. These require cooperation among nuclear community. The cooperation should be more pronounced by heterogeneous growing Asian countries to reach harmony for mutual benefits toward better civilization.

  15. Advantages and risks of nuclear energy

    A comprehensive analysis and comparison of different energy resources available to human usage. The first in the row is the fossil energy, obtained by burning hydrocarbons and its effects, i.e. acid rains and global warming. A second example is that of renewable sources, like hydro energy and its effects like the problems generated by the necessary dams. Other renewables are wind energy, used on a small scale yet, basically clean, however with damaging effects like noise, and solar energy. Nuclear energy has its own risks, generated mainly by nuclear accidents. However, the mainly open cycle fuel consumption has the problem of creating radioactive nuclear waste. Safety in nuclear power plants is based on negative feed-back, the principles of single failure, diversity and depth protection, including the importance of human factor. The breakdown on April 10, 2003 at Paks PWP NPP is also analysed. It has been caused by residual heat during a maintenance process in an already stopped reactor, lacking proper cooling. (Gy.M.)

  16. Nuclear energy and the media

    Mosey, D.

    1985-01-01

    The author believes that it is very important for the public to understand the scientific and engineering realities of nuclear energy systems, so that their support for or their opposition to energy policy decisions will not be based on false premises. While there do exist widespread misconceptions about the safety of nuclear energy, these misconceptions spring from the high degree of emphasis placed on engineered safety by the nuclear energy community in their communications with the public. That this situation continues to exist is largely the result of either a failure of the technocrats to require their professional communicators to learn the elements of the subject or a refusal of these communicators to do so, combined with an underestimation on the part of both groups of public capacity for understanding. The nuclear energy community's concern about public acceptance of its product is to a certain extent misplaced at the present time. Its communication efforts have been image-oriented and generalized and have eschewed technical rigour. The important issue of scientific and engineering illiteracy, especially among those groups with significant input to policy decisions, is being neglected

    In Belgium, approximately 60 percent of the produced electricity is generated by nuclear power. At present, nuclear power production tends to stagnate in Europe and North America but is still growing in Asia. The document gives an overview of the present status and the future energy demand with emphasis on electric power. Different evaluation criteria including factors hindering and factors promoting the expansion of nuclear power as well as requirements of new nuclear power plants are discussed. The extension of the lifetime of existing facilities as well as fuel supply are taken into consideration. A comparative assesment of nuclear power with other energy sources is made. The report concludes with estimating the contribution and the role of nuclear power in future energy demand as well as with an overview of future reactors and research and development programmes.

  20. European Nuclear Young Generation. Position Paper on Nuclear Energy and the Environment

    International Nuclear Information System (INIS)

    2015-01-01

    The world population is continually growing; from 1 billion in 1800 to 7 billion in 2011, we are expected to reach 10 billion by the end of the 21. century. To sustain this population growth, an increased energy supply is required to provide sufficient clean water, health care, education, food, shelter, communication and transportation. Whereas energy access is today guaranteed in OECD countries, around 1.3 billion people still live without sufficient access to energy. Affordable and reliable sources of energy are required to sustain our development. At the same time, it is now acknowledged by the scientific community that human activities are mainly responsible for climate change. Our growing energy-intensive societies are accelerating climate change and its associated consequences: rise of ocean levels, more frequent extreme meteorological phenomena and massive loss of biodiversity; consequences that must be prevented at all costs. We need sustainable, affordable, reliable and safe sources of energy. It is our responsibility to promote low carbon energies and responsible consumer behaviors that will prevent social and environmental disasters for current and future generations. Nuclear, a solution? Nuclear power is regarded by many as being environmentally friendly. Nuclear power plants have nearly no CO 2 emission, while the nuclear industry is recognized as one of the safest industries; backed by stringent safety standards, transparency culture and international cooperation based on an evolution of lessons learnt from a variety of operations. Moreover, solutions for decommissioning and waste management exist and are already implemented in most European countries. Nuclear power is affordable and reliable. Nuclear power has one of the lowest production costs within the energy market, this stems from production costs which mainly depend upon the investment costs; fuel and operating costs have little impact on the price of nuclear electricity. Nuclear generation is

  1. Nuclear energy: salvaging the atomic age

    Weinberg, A.M.

    1979-01-01

    The history of atomic power is reviewed from the first chain reaction in Chicago in 1942 to the worst-to-date accident at the Three Mile Island power plant in March, 1979. While media coverage during the Three Mile Island incident made the public aware of some reactor hardware and radiation hazards, Weinberg suggests that an acceptable nuclear future should have six characteristics: increased physical isolation of reactors, further technical improvements, separation of generation and distribution, professionalization of the nuclear cadre, heightened security, and public education about the hazards of radiation. Weinberg feels the question of low-level radiation effects to be critical to public acceptance of nuclear energy. Since the effects (if any) are so rarely seen because exposures are so small, the issue may be beyond the ability of science to decipher. Weinberg again explains his reference to nuclear energy as a Faustian Bargain: ''...nuclear energy, that miraculous and quite unsuspected source of energy, demands an unprecedented degree of expertise, attention to detail, and social stability. In return, man has, in the breeder reactor, an inexhaustible energy source.''

  2. Nuclear energy: From swords to ploughshares

    International Nuclear Information System (INIS)

    Knapp, V.

    1999-01-01

    There cannot be any doubt that the promise of nuclear energy is one of the greatest offered to man. For an overpopulated and exhausted Earth, salvation is in energy, to feed the population through energy intensive agriculture, to reuse resources by recycling. Modern transport, communications, housing and so on, everything which constitutes the standard of living of the developed world, can be very directly translated into energy. Although the relationship between the artefact and the energy required to produce it can be more or less efficient, it cannot be circumvented. So, unless the right to develop and enjoy higher standards of living be denied to the underdeveloped billions of the world, much more energy will be needed in future. However, already we are facing the limits in expansion of energy consumption. A greenhouse effect and the related climate changes demand that a brake be put on the use of fossil fuels. So what are the prospects? Scientifically speaking they are excellent. There are two inexhaustible energy sources on which to build the future development; solar energy and nuclear energy. The case of solar energy is a straightforward one, at least in principle. It is the case of solving technical problems to make it economically attractive and competitive. When and if this is achieved there will be no political barriers to its massive use. The case of nuclear energy carries enormous political problems, because of the undeniable connection between the peaceful use and the possibility of military abuse of nuclear technology. Although the promise of nuclear energy is enormous, correspondingly great are the preconditions for its safe large scale use. However, if these preconditions are also conducive to a better, more united world, then it is worthwhile to work in that direction. Nuclear energy should be considered neither from the narrow technical point of view, nor from the point of view which neglects the needs and rights of the large part of humanity

  3. Reconsidering the role of nuclear energy

    International Nuclear Information System (INIS)

    Uematsu, K.

    1990-01-01

    The use of nuclear power is being reconsidered in the light of the present environmental debate. The extreme rise in the world-wide consumption of fossil energy resources has given rise to the climatological problem and will, at some point in time, lead to the depletion of fossil resources. There is no doubt that the use of nuclear power does not generate any CO 2 emissions, but nuclear power alone is not able to meet tomorrow's world energy requirement. Expanding the worldwide use of fossil fuels is no solution either. To what extent nuclear power will be used depends on the severity of the environmental problems, but also on the alternatives made available economically by new technical concepts. A major role is palyed by the human attitude to nuclear power, which is now influenced by too many emotions. Weighing the risks inherent in all energy resources, and considering the growing energy requirement in the developing countries, will lead to parameters which will be instrumental in determining the future of nuclear power.

    The objective of the presented research was to establish the presence and the structure of nuclear energy as a theme in Slovenian mass media and at the same time to answer the question what chances an active Slovenian reader had in the year 1991 to either strengthen or change his opinion on nuclear power. Measurement and analysis of chosen relevant variables in 252 contributions in six Slovenian mass media publications in the year 1991 showed that the most frequent nuclear theme was decommissioning and closing down of a nuclear power plant. Other themes followed in the order of the frequency of appearance: nuclear energy as an economic issue, waste disposal, NPP Krsko operation, influence on health, information about events, seismic questions. The scientific theme - nuclear energy, was intensely represented in chosen Slovenian mass media publications in 1991. Common to all nuclear themes is that they were being presented from the political point of view. (author) [sl

  7. Promise and peril of nuclear energy

    International Nuclear Information System (INIS)

    Weaver, K.F.

    1979-01-01

    Against the backdrop of a national debate ranging from total opposition to nuclear energy development to a recognition of its necessity are the facts that 70 nuclear plants in 27 states are now generating one-eighth of the nation's electrical needs. An overview of the nuclear fuel cycle, the global distribution of nuclear power, and the alternatives to nuclear energy are followed by a discussion of the major points of controversy. The debate has focused on the safety of nuclar plants and the handling, storing, and security of radioactive materials. Critics challenge transport methods and the handling of waste disposal. The author reviews procedures used in the US and in some of the 43 other countries having nuclear energy programs. The future of nuclear power in the face of citizen protests and the threat of international terrorism is concluded to remain a picture clouded by emotion and uncertainty unless regulatory and construction delays can be eased and unless the necessary capital and public acceptance can be developed

  9. A perfect match: Nuclear energy and the National Energy Strategy

    International Nuclear Information System (INIS)

    1990-11-01

    In the course of developing the National Energy Strategy, the Department of Energy held 15 public hearings, heard from more than 375 witnesses and received more than 1000 written comments. In April 1990, the Department published an Interim Report on the National Energy Strategy, which compiles those public comments. The National Energy Strategy must be based on actual experience and factual analysis of our energy, economic and environmental situation. This report by the Nuclear Power Oversight committee, which represents electric utilities and other organizations involved in supplying electricity from nuclear energy to the American people, provides such an analysis. The conclusions here are based on hard facts and actual worldwide experience. This analysis of all the available data supports -- indeed, dictates -- expanded reliance on nuclear energy in this nation's energy supply to achieve the President's goals. 33 figs

    2006-01-01

    Since the ecological footprint analysis in 1970s suggested changing consumption patterns and overpopulation concerns, energy policy such as energy conservation and use of renewable energy has become of prime importance. Several results of the long-term energy demand and supply analysis in 2050 or 2100 to reduce drastically carbon dioxide emission as a measure against global warming, showed the necessity of nuclear power deployment as well as maximum efforts to save energy, exploitation of the separation and disposal of carbon dioxide, and shifting energy sources to fuels that emit less greenhouse gases or non-fossil fuels. As a promising means to contribute to long-term energy supply, nuclear power generation is expected with improving safety, economic efficiency, environmental adaptability, and nuclear proliferation resistance of the technologies.

    Myers, D.K.; Johnson, J.R.

    1980-01-01

    Both the light water reactor and the Canadian heavy water reactor systems produce electricity cheaply and efficiently. They produce some fissionable byproducts, which can be recycled to extend energy sources many-fold. Besides the production of electrical power, the nuclear industry produces various radioistopes used for treatment of cancer, in diagnostic procedures in nuclear medicine, in ionization smoke detectors, and as radioactive tracers with various technological applications including the study of the mechanisms of life. The increment in environmental radiation levels resulting from operation of nuclear power reactors represents a very small fraction of the radiation levels to which we are all exposed from natural sources, and of the average radiation exposures resulting from diagnostic procedures in the healing arts. The total health hazard of the complete nuclear power cycle is generally agreed to be smaller than the hazards associated with the generation of an equal amount of electricity from most other currently available sources of energy. The hazards from energy production in terms of shortened life expectancy are much smaller in all cases than the resulting increase in health and life expectancy. (auth)

    A global energy, economics, environment (E 3 ) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Using this model, consistent nuclear energy scenarios are constructed. A spectrum of future is examined at two levels in a hierarchy of scenario attributes in which drivers are either external or internal to nuclear energy. Impacts of a range of nuclear fuel-cycle scenarios are reflected back to the higher-level scenario attributes. An emphasis is placed on nuclear materials inventories (in magnitude, location, and form) and their contribution to the long-term sustainability of nuclear energy and the future competitiveness of both conventional and advanced nuclear reactors

    The Korean government announced the 'Basic Plan for National Energy towards 2030' last year. The goal of the plan is to achieve energy security, energy efficiency and environmental protection. To achieve green development Korean government plans to increase the portion of nuclear and renewable energy and reduce that of coal and oil energy. According to the plan, Korea will build another 9 units until 2030 and nuclear energy will represent 59% of electricity demands by 2030 which is about 20% higher than last year. Even though environment surrounding the nuclear industry is changing favorably and the government has a plan to increase nuclear energy for green development and optimal energy mix, we have to meet some challenges in the area of safety, waste disposal, public acceptance, and technology development. In this paper, we introduced the history, current status and future prospect of the nuclear industry in Korea, discussed new roles of nuclear energy, and made suggestions how to meet challenges and brace up for the global nuclear renaissance.

    2010-12-20

    We study the bulk deformation properties of the Skyrme nuclear energy density functionals. Following simple arguments based on the leptodermous expansion and liquid drop model, we apply the nuclear density functional theory to assess the role of the surface symmetry energy in nuclei. To this end, we validate the commonly used functional parametrizations against the data on excitation energies of superdeformed band-heads in Hg and Pb isotopes, and fission isomers in actinide nuclei. After subtracting shell effects, the results of our self-consistent calculations are consistent with macroscopic arguments and indicate that experimental data on strongly deformed configurations in neutron-rich nuclei are essential for optimizing future nuclear energy density functionals. The resulting survey provides a useful benchmark for further theoretical improvements. Unlike in nuclei close to the stability valley, whose macroscopic deformability hangs on the balance of surface and Coulomb terms, the deformability of neutron-rich nuclei strongly depends on the surface-symmetry energy; hence, its proper determination is crucial for the stability of deformed phases of the neutron-rich matter and description of fission rates for r-process nucleosynthesis.

    This study evaluated the role of nuclear energy in various aspects in order to provide a more comprehensive standard of judgement to the justification of the utilization of nuclear energy. Firstly, this study evaluated the economic value addition of nuclear power generation technology and Radio-Isotope(RI) technology quantitatively by using modified Input-Output table. Secondly, a comprehensive cost-benefit analysis of nuclear power generation was conducted with an effort to quantify the foreign exchange expenditure, the environmental damage cost during 1986-2015 for each scenario. Thirdly, the effect of the regulation of CO 2 emission on the Korean electric supply system was investigated. In more detail, an optimal composition of power plant mix by energy source was investigated, under the assumption of the CO 2 emission regulation at a certain level, by using MESSAGE model. Finally, the economic spillover effect from technology self-reliance of NSSS by Korea Atomic Energy Research Institute was evaluated. Both production spillover effect and value addition spillover effect were estimated by using Input-Output table

    A nuclear energy system should provide a stable supply of energy without endangering the environment or humans. If there is fear about exhausting world energy resources, accumulating radionuclides, and nuclear reactor safety, tension is created in human society. Nuclear energy systems of the future should be able to eliminate fear from people's minds. In other words, the whole system, including the nuclear fuel cycle, should be self-consistent. This is the ultimate goal of nuclear energy. If it can be realized, public acceptance of nuclear energy will increase significantly. In a self-consistent nuclear energy system, misunderstandings between experts on nuclear energy and the public should be minimized. The way to achieve this goal is to explain using simple logic. This paper proposes specific targets for self-consistent nuclear energy systems and shows that the fast breeder reactor (FBR) lies on the route to attaining the final goal

    2008-01-01

    One of the main constraints to adopt a nuclear program is the public acceptance. In Mexico, at least, it lacks of an adequate promotion of its benefits and challenges. A big stigma for nuclear electricity production is the association with nuclear weapons, along with myths and misconceptions and bad information about nuclear energy. Mexico has adopted an energy policy to diversify the electricity sources and nuclear energy is among the alternatives to achieve this goal because current studies show that is a safe and a competitive option from an economical point of view. Public opinion plays a very important role in the policy decision making to adopt the deployment of new reactor units; therefore it is necessary to define communication strategies to promote nuclear energy. The current study is an investigation to learn what is the perception and positioning about nuclear energy as a starting point to define the way to improve public acceptance. The national assessment carry on here is divided in two parts, the first one is a qualitative study to know knowledge level, associations and nuclear perception, identifying controversy items and expectations about advantages and disadvantages to define the adequate question to be used in the second part, which is a quantitative study that shows the acceptance of nuclear energy at national level and in particular in two sites that are suitable to deploy new nuclear reactors. From the results of this study some communication and persuasion strategies to improve public perception are defined and they could be used as part of a nuclear program. (author)

    Hodgson, Peter E.

    2005-01-01

    The paper describes the author's view on the environmental problems and nuclear power. The world demand for energy has increased rapidly due to the increase of population and the overall rise in living standards, resulting in many signs that the world is experiencing a growing shortage of energy and continuing need for flexible planning and the search for new sources. Fossil fuels are polluting the atmosphere, leading to climate change, acid rain and global warming. This has led many countries to look again at nuclear power. For the widespread opposition to nuclear power, the author lists up the fear of nuclear weapons, the fear of nuclear radiations including reprocessing plants as well as natural radioactivity and cosmic rays, the fear about the safety of nuclear reactors, and production of large amount of radioactive wastes. The author compares various energy sources, and insists that there is a strong reluctance to face the truth, as Governments knowing that nuclear power is politically so unpopular would not advocate the construction of new nuclear stations.

    Energy release process in nuclear reactions induced by fast hadrons in hadron-nucleus collisions is discussed. Some portion of the internal nuclear energy is released when the locally damaged in a collision, and instable therefore, residual target nucleus transits itself into light nuclear fragments (nucleons, D, T) and a stable lighter final nucleus or some number of stable lighter nuclei. It is not excluded that in some of the collisions the induced intranuclear nuclear reactions may be energy overcompensating. Corresponding reconnaissance should be made - in analysing the nuclear reactions induced in hadron-nucleus collisions

    The world faces serious difficulties in obtaining the energy that will be needed in coming decades for a growing population, especially given the problem of climate change caused by fossil fuel use. This book presents a view of nuclear energy as an important carbon-free energy option. It discusses the nuclear fuel cycle, the types of reactors used today and proposed for the future, nuclear waste disposal, reactor accidents and reactor safety, nuclear weapon proliferation, and the cost of electric power. To provide background for these discussions, the book begins with chapters on the history of the development and use of nuclear energy, the health effects of ionizing radiation, and the basic physics principles of reactor operation. The text has been rewritten and substantially expanded for this edition, to reflect changes that have taken place in the eight years since the publication of the first edition and to provide greater coverage of key topics. These include the Yucca Mountain repository plans, designs ...

  7. Peaceful nuclear energy to Saudi Arabia

    Melibary, A.R.; Wirtz, K.

    1980-11-01

    The argument for and against the application of peaceful nuclear energy in Saudi Arabia is discussed in terms of the country's industrial development and power requirement for electricity and desalination. The discussion leads to the conclusion that due to its large oil reserve, Saudi Arabia may tolerate a considerate approach to nuclear energy up to the year 2000. Beyond this date, nuclear energy should be used in order to achieve the desired industrial maturity in the country. The introduction of nuclear energy, however, will be faced with three constraints, namely man power availability, cooling water requirement, and the size of the electrical grid. The period 1980-2000 is thus most suitable for important preparation steps, among which are the adoption of regulatory provisions, establishment of nuclear facilities with necessary equipments, and staff training for regulatory, organizational, and technical activities. The paper outlines a scheme for the initiation steps and efforts to meet these requirements. (orig.) [de

    With the beginning of the exploitation of nuclear energy by over fifty years experience, a new kind of human disasters which were not known by all world languages were included as new terms not audible before such as radiation protection and risk issues. This was given the attention of people at all levels in view of nuclear terror by bombing the first nuclear bomb on Hiroshima-Japan on 6 August 1945 and the second nuclear bomb on Nagasaki on 9 August 1945. At the end of World War II scientists and officials realized the political and military risks of nuclear energy and its destructive side with benefits and positive repercussions. Atomic energy is produced from great power that God placed in the nucleus of the atom, where nuclear energy is liberated when a change in the structure of the atom and its formations happens or so-called nuclear reaction.

    The nuclear energy is attracting renewed interest of public and policy makers due to his potential role in long term strategies aiming to reduce the risk of global warming and in a more general, to carry out sustainable policies, however, any project of nuclear nature arise concerns about the risks associated with the release of radioactivity during accident conditions, radioactive waste disposal and nuclear weapons proliferation. Then in light of the likeliness for a new nuclear project in Mexico, is necessary to design a strategy to improve the social acceptance of nuclear power. This concern is been boarding since the environmental and economic point of view. The information that can change the perception of nuclear energy towards increase public acceptance, should be an honest debate about the benefits of nuclear energy, of course there are questions and they have to be answered, but in a realistic and scientific way: So thinking in Mexico as a first step it is important to communicate to the government entities and political parties that nuclear energy is a proven asset that it is emission free and safe. Of course besides the guarantee of a proven technology, clean and safe relies the economic fact, and in Mexico this could be the most important aspect to communicate to key people in government. Based in the Laguna Verde survey it is clear that we have to find the adequate means to distribute the real information concerning nuclear technology to the public, because the results shows that Mexican people does not have complete information about nuclear energy, but public can support it when they have enough information. From the IAEA study we can say that in Mexico public acceptance of nuclear energy it s not so bad, is the highest percentage of acceptance of nuclear technology for health, considering benefits to the environment Mexican opposition to build new plants is the second less percentage, and generally speaking 60% of the people accept somehow nuclear

    Iran says it aims at developing nuclear energy and mastering the whole cycle of nuclear combustion. After the withdrawal of Western experts, Russia took over the building of nuclear plants, without clearly explaining what it really intended to do. Nowadays Iran has no international assistance, either to complete the nuclear plants, or to achieve full control of the nuclear combustion cycle. Going forward seems difficult, even though Iran has proved capable of mobilizing a good deal of energy to attain its target

    Energy Technology Data Exchange (ETDEWEB)

    Kozier, K.S

    1999-10-01

    Nuclear energy generated in fission reactors is a versatile commodity that can, in principle, satisfy any and all of mankind's energy needs through direct or indirect means. In addition to its dominant current use for electricity generation and, to a lesser degree, marine propulsion, nuclear energy can and has been used for process heat applications, such as space heating, industrial process heating and seawater desalination. Moreover, a wide variety of reactor designs has been employed to this end in a range of countries. From this spectrum of experience, two design approaches emerge for nuclear process heating (NPH): extracting a portion of the thermal energy from a nuclear power plant (NPP) (i.e., creating a combined heat and power, or CHP, plant) and transporting it to the user, or deploying dedicated nuclear heating plants (NHPs) in generally closer proximity to the thermal load. While the former approach is the basis for much of the current NPH experience, considerable recent interest exists for the latter, typically involving small, innovative reactor plants with enhanced and passive safety features. The high emphasis on inherent nuclear safety characteristics in these reactor designs reflects the need to avoid any requirement for evacuation of the public in the event of an accident, and the desire for sustained operation and investment protection at minimum cost. Since roughly 67% of mankind's primary energy usage is not in the form of electricity, a vast potential market for NPH systems exists, particularly at the low-to-moderate end-use temperatures required for residential space heating and several industrial applications. Although only About 0.5% of global nuclear energy production is presently used for NPH applications, an expanded role in the 21st century seems inevitable, in part, as a measure to reduce greenhouse gas emissions and improve air quality. While the technical aspects of many NPH applications are considered to be well proven, a

    The Fukushima nuclear accident has become one of the worst accidents in nuclear history and it is not completely over yet. It will take at least 30 years or more to decontaminate and decommission the crippled nuclear reactors on site. Still, more than 140,000 people are away from home and restoring and assuring the life and welfare of those evacuated people is the top priority of Japanese government's nuclear energy policy. The government will release its new energy policy soon which will state that nuclear power is considered as an important base load electricity source, while committing to reduce its dependence as much as possible. For nuclear energy policy, there are certain important issues to be overcome regardless of future of nuclear power in Japan. They are: (1) spent fuel management and radioactive waste disposal, (2) restoring public trust (3) securing human resources and (4) plutonium stockpile management.

    This paper embraces most of the matters discussed at a recent debate held by the Oxford Environmental Group. The author attempts (a) to explain why nuclear power is needed and why there is no sensible alternative, (b) attempts to put nuclear hazards in perspective and to expose some of the fallacies in the arguments advanced by environmentalist and conservationist groups, and (c) shows why more rapid progress may be expected in future in the building up of nuclear power. Amongst matters discussed are - zero economic growth proposals, the energy gap, world nuclear programme, nuclear fuel supplies, nuclear energy as the only viable prospect, and assessment of nuclear hazards. It is concluded that the momentum of the nuclear programme must be maintained if nuclear energy is to provide the insurance against future fuel problems that it alone can provide. (U.K.)

    Evolutionary progress of the LWR plants in the last half-century was reviewed in series. As a prehistory of nuclear energy development, this first lecture presented (1) discovery of nuclear energy and development of the atomic bomb and (2) development of the reactor system using nuclear energy for making electricity and for naval propulsion. The first nuclear reactor to produce electricity was the small Experimental Breeder Reactor (EBR-1) in Idaho, in the USA, which started up in December 1951. The Pressurized Water Reactor (PWR) for naval use was developed under Hyman Rickover in the USA. The Mark I prototype naval reactor started up in March 1953 in Idaho, and the first nuclear-powered submarine, NS Nautilus, with the Mark II reactor was put into service in January 1955. (T. Tanaka)

    Schmidt, F.H.; Bodansky, D.

    1975-02-01

    The objective of the paper presented is to show that nuclear fission power is the best, and maybe the only, alternative source of energy. It is written for a wide range of readers, including non-scientists and scientists who are not particularly informed on the issues involved. The first question considered concerns man's need for energy; it is concluded that conservation measures alone cannot suffice. Next, the earth's energy sources are examined, and the extent of each is estimated in the simple context of the length of time it could last at present use rates. Only nuclear fission, nuclear fusion, and solar energy can provide for future time scales commensurate with man's historic past, while avoiding the possibility of catastrophic social upheaval. Fusion and solar energy are rejected on technological grounds because the world energy problem is so pressing that one cannot gamble on hopes for future technological breakthroughs. Thus, only nuclear fission meets the twin criteria of technological feasibility and adequate resource base. Each of the controversial issues surrounding nuclear fission energy is examined in some detail. The conclusion is reached that none is serious, and that nuclear fission offers by far the best energy source from environmental, economic, longevity, and overall safety standpoints

    The Malaysian Vision 2020 envisages doubling of the its economy every ten years for the next three decades. The Second Outline Perspective plan 1991-2000 (OPP2), also known as the National Development Policy (NDP) will set the pace to enable Malaysia to become a fully developed nation by the year 2020. The Malaysian economy is targeted to grow at 7 percent per annum in the decade of OPP2. In view of the targets set under Vision 2020, it is important to ensure that energy does not become a constraint to growth, and this sector develops in a least cost basis. Energy is crucial for industrialization and no modern industrial state can function without it. The paper presents a description of the main utilities in the country. Their installed capacities, maximum demand, generation mix and customers served are discussed. The electricity demand forecast till the year 2020 is presented. The paper presents this for 4 scenarios - a low growth, business as usual scenario, a moderate growth, business as usual scenario, a moderate growth, energy efficient scenario and a targeted growth, energy efficient scenario. The energy resources in the country is described together with its energy policy. The country's four-fuel policy is elaborated with the various options discussed. The environmental and pricing policies with regards to energy is also briefly given. Finally the nuclear option is presented in this context of the country's energy policy. The country had undertaken various studies for the nuclear option. These studies are given in the paper. The purpose of these studies and what the government decided is also discussed. Finally the prospects for the nuclear option in the future for the country is discussed. It is concluded that while, for the present, the nuclear option is not considered by the government, this may not be so in the future. The various reasons for this is given and the paper concludes that it may be prudent to keep this option under constant review. (J.P.N.)

    Nuclear energy contributes 17% to global electricity production and almost 40% to the public supply in Germany. Operators of nuclear power plants are having to invest considerable effort in trying to set the public thinking and boring public opinion away from an emotional rejection towards a rational consideration of the risks of different energy systems. It is argued that in view of the specific problems of environmental pollution through CO 2 it should be possible to bring about public acceptance of nuclear energy utilization. (DG) [de

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

    As an oil-and gas-rich state, Iran is among the main energy exporting countries of the world. No doubt, economic development in a country causes increase in its energy demand. Having a glance at the statistics of energy consumption in Iran during the past three decades reveals that energy consumption has been quadrupled. Due to dependability of the country's energy-supply system on fossil industries and thanks to the increasing demand, social and economic development will face great problems. For this reason, the problem has prompted Iranian officials to diversify the country's energy-supply system, as it has been give top priority in the policies of the first and second plans. The discovered and undiscovered fields of applied nuclear sciences and technologies indicate the importance of transferring and developing nuclear technologies for different countries' economic systems. Like many other countries, Iran is also in dire need of transferring nuclear technology and applying the related sciences in various fields, paving the way for economic, agricultural, medical development and having a more active presence in the international markets through quality and standard products. Iran has all the time called for a Middle East region free of nuclear weapons and expressed its concern over production and development of atomic weapons by certain regional countries and called it a serious threat to its national and regional security

    Symonds, J.L.; Essam, P.; Stocks, K.

    1976-01-01

    Energy analysis is a systematic way of tracing and accounting for the flows of energy through an industrial system and apportioning a quantity of the primary energy input to each of the goods and services sent out. The application of energy accounting to nuclear power stations and their growth in generating systems is discussed. Misunderstandings arising from discrepancies and weaknesses in some published simple analyses of hypothetical growth situations are outlined. Results of a more complex energy flow analysis are used to demonstrate that current nuclear energy programs are running at an energy profit. Large fossil fuel savings will occur in a real electrical grid system under anticipated nuclear power growth rates. These savings will give a new dimension in planning the use of fossil energy resources which will still be needed for transport and industrial processes, such as steelmaking, for some time to come.

  17. Global Nuclear Energy Partnership Programmatic Environmental Impact Statement

    2008-01-01

    The proposed Global Nuclear Energy Partnership (GNEP) Program, which is part of the President's Advanced Energy Initiative, is intended to support a safe, secure, and sustainable expansion of nuclear energy, both domestically and internationally. Domestically, the GNEP Program would promote technologies that support economic, sustained production of nuclear-generated electricity, while reducing the impacts associated with spent nuclear fuel disposal and reducing proliferation risks. The Department of Energy (DOE) proposed action envisions changing the United States nuclear energy fuel cycle from an open (or once-through) fuel cycle - in which nuclear fuel is used in a power plant one time and the resulting spent nuclear fuel is stored for eventual disposal in a geologic repository - to a closed fuel cycle in which spent nuclear fuel would be recycled to recover energy-bearing components for use in new nuclear fuel. At this time, DOE has no specific proposed actions for the international component of the GNEP Program. Rather, the United States, through the GNEP Program, is considering various initiatives to work cooperatively with other nations. Such initiatives include the development of grid-appropriate reactors and the development of reliable fuel services (to provide an assured supply of fresh nuclear fuel and assist with the management of the used fuel) for nations who agree to employ nuclear energy only for peaceful purposes, such as electricity generation.

    2004-01-01

    There is general agreement that hydrogen as an universal energy carrier could play increasingly important role in energy future as part of a set of solutions to a variety of energy and environmental problems. Given its abundant nature, hydrogen has been an important raw material in the organic chemical industry. At recent years strong competition has emerged between nations as diverse as the U.S., Japan, Germany, China and Iceland in the race to commercialize hydrogen energy vehicles in the beginning of 21st Century. Any form of energy - fossil, renewable or nuclear - can be used to generate hydrogen. The hydrogen production by nuclear electricity is considered as a sustainable method. By our presentation we are trying to evaluate possibilities for sustainable hydrogen production by nuclear energy at near, medium and long term on EC strategic documents basis. The main EC documents enter water electrolysis by nuclear electricity as only sustainable technology for hydrogen production in early stage of hydrogen economy. In long term as sustainable method is considered the splitting of water by thermochemical technology using heat from high temperature reactors too. We consider that at medium stage of hydrogen economy it is possible to optimize the sustainable hydrogen production by high temperature and high pressure water electrolysis by using a nuclear-solar energy system.

    2014-01-01

    The nuclear energy response for mitigating global climate change across eighteen participating models of the EMF27 study is investigated. Diverse perspectives on the future role of nuclear power in the global energy system are evident in the broad range of nuclear power contributions from participating models of the study. In the Baseline scenario without climate policy, nuclear electricity generation and shares span 0 - 66 EJ/ year and 0 - 25% in 2100 for all models, with a median nuclear electricity generation of 39 EJ/year (1,389 GWe at 90% capacity factor) and median share of 9%. The role of nuclear energy increased under the climate policy scenarios. The median of nuclear energy use across all models doubled in the 450 ppm CO2e scenario with a nuclear electricity generation of 67 EJ/year (2,352 GWe at 90% capacity factor) and share of 17% in 2100. The broad range of nuclear electricity generation (11 - 214 EJ/year) and shares (2 - 38%) in 2100 of the 450 ppm CO2e scenario reflect differences in the technology choice behavior, technology assumptions and competitiveness of low carbon technologies. Greater clarification of nuclear fuel cycle issues and risk factors associated with nuclear energy use are necessary for understanding the nuclear deployment constraints imposed in models and for improving the assessment of the nuclear energy potential in addressing climate change

  3. Can we live without nuclear energy?

    International Nuclear Information System (INIS)

    Lipphardt, G.

    1987-01-01

    Demands for a withdrawal of nuclear energy are usually based on alleged safety deficiencies of nuclear power plants. Renewable energy sources, electricity saving and heat-power coupling should make possible the replacement of nuclear power plants. But are solar and wind energy sources real alternatives, by which electricity can be generated cheaply and sufficiently? Or could the energy problem be solved by saving energy without lowering our standard of living and narrowing the development of our industry? Must we instead burn expensive and rare fossil fuels that also have many disadvantages? For the chemical industries of the Federal Republic of Germany and Switzerland who are very large electricity consumers these are essential questions, on which their future competitiveness depends. The question naturally then arises whether our nuclear power plants are really so unsafe that we are obliged to accept solutions that are far from ideal. The present technical and economical article tries to answer these questions. 22 refs., 9 figs., 1 tab

    This article analyses the different technological alternatives for addressing the energy challenges of our society (security of supply, competitiveness and sustain ability), emphasizing the need for nuclear energy to achieving those goals. Recently, the view of society about nuclear power has shifted from a position of outright hostility towards an acceptance still not totally defined. That is so, that people of environmentalism as the founders of Green peace James Love lock, Patrick Moore or the writer Gwyneth Cravens have said that nuclear energy is the option to produce energy that less increases CO 2 emissions, and that without it targets for reduction may not meet.

    2006-01-01

    Deregulation and new environmental requirements combined with the growing scarcity of fossil resources and the increasing world energy demand lead to a renewal of the debate on tomorrow's energies. Specifically, nuclear energy, which has undeniable assets, faces new constraints. On the one hand, nuclear energy is very competitive and harmless to greenhouse effect. From this point, it seems to be an ideal candidate to reach future objectives of sustainability, availability and acceptability. On the other hand, its technology of production - based on fission - remains imperfect and generates risks for environment and health. In this respect, it is less desirable. Therefore, world researchers turn today towards another type of nuclear technique, fusion, on which the project ITER is founded. This worldwide project is interesting for our analysis because, as a technological revolution, it takes into consideration all the global challenges of nuclear energy for the future, and particularly its capacity to meet the increasing energy needs of developing countries. It is the example par excellence of a successful international scientific collaboration oriented towards very long-run energy ends that involve huge technological, economic and political stakes. Focusing on this project, we thus have to reconsider the future place of nuclear energy in a more and more demanding world. Considering the magnitude of the efforts undertaken to implement ITER, this paper aims at analysing, in a detailed way, its goals, its challenges and its matter

    During the past decade the interest in hydrogen as transportation fuel has greatly escalated. This heighten interest is partly related to concerns surrounding local and regional air pollution from the combustion of fossil fuels along with carbon dioxide emissions adding to the enhanced greenhouse effect. More recently there has been a great sensitivity to the vulnerability of our oil supply. Thus, energy security and environmental concerns have driven the interest in hydrogen as the clean and secure alternative to fossil fuels. Remarkable advances in fuel-cell technology have made hydrogen fueled transportation a near-term possibility. However, copious quantities of hydrogen must be generated in a manner independent of fossil fuels if environmental benefits and energy security are to be achieved. The renewable technologies, wind, solar, and geothermal, although important contributors, simply do not comprise the energy density required to deliver enough hydrogen to displace much of the fossil transportation fuels. Nuclear energy is the only primary energy source that can generate enough hydrogen in an energy secure and environmentally benign fashion. Methods of production of hydrogen from nuclear energy, the relative cost of hydrogen, and possible transition schemes to a nuclear-hydrogen economy will be presented.

    Nuclear energy has been used as a source of clean energy with many benefits. Nevertheless, it is still addressed with prejudice. The atomic bombing of Hiroshima and Nagasaki during World War II (1945), the Three Mile Island accident (1979), Chernobyl accident (1986), the crash of the cesium-137 in Goiana, Brazil (1987), and the recent accident in Fukushima (2011) may have been responsible for the negative image of nuclear energy. Researches on education have been conducted with students concerning the conceptual and practical issues of nuclear energy. This work aims to review the literature about nuclear energy education around the world in both, elementary school and high school. Since most educational researches on nuclear energy were published after 1980, this literature review covered the researches that have been published since 1980. The data were presented in chronological order. The results from the literature review provided a clear visualization of the global nuclear energy educational scenario, showing that the theme is still addressed with prejudice due to an incorrect view of nuclear energy and a limited view of its benefits. Concerning the science textbooks, the literature reports that the theme should be better addressed, encouraging students to research more about it. The data from this literature review will serve as a reference for a future proposal for a teaching training program for Brazilian science/physics high school teachers using a new teaching approach.

    Nuclear damage compensation and energy reform were closely related. Nuclear damage compensation cost should be part of generation cost of nuclear power. Extend of nuclear damage compensation was limited by compensation standard of Tokyo Electric Power Co. (TEPCO) following guidelines of Dispute Reconciliation Committee for Nuclear Damage Compensation. TEPCO had already paid compensation of about two trillion yen until now, which was only a part of total damage compensation cost. TEPCO had been provided more than 3.4 trillion yen by Nuclear Damage Liability Facilitation Cooperation, which would be put back by nuclear operators including TEPCO. TEPCO could obtain present raising funds and try to reconstruct business with restart of nuclear power, which might disturb energy reform. Present nuclear damage compensation scheme had better be reformed with learning more from Minamata disease case in Japan. (T. Tanaka)

    The Broad Outline of Nuclear Energy Policy for about ten years was determined by the Cabinet meeting of Japan. Nuclear power plant safety and regulation, nuclear waste management, nuclear power production and nuclear power research and development were discussed. It determined that 3 nuclear power plants, which are building, should be built, and about 10 plants will be built to product 30 to 40 % of Japan electricity generation after 2030. FBR will be operated until 2050. The nuclear fuel cycle system will be used continuously. The nuclear power plant safety and nuclear waste management are so important for the nuclear industry that these subjects were discussed in detail. In order to understand and use the quantum beam technology, the advanced institutions and equipments and network among scientists, industry and people should be planed and practically used. (S.Y.)

    This colloquium took place less than 1 year after the decision of the US of revival of their nuclear program. Thus the international context has changed, even if nuclear contestation remains as strong as in the past. Among governments, some positions preach the banishment of nuclear energy while others consider the nuclear option as the only solution to meet the growing up energy demand and the future environmental and economical stakes. This report makes a synthesis of the different talks given by the participants during the 3 round tables of the colloquium on the future of nuclear energy: the ecological stake, the democratic stake, and the energy policy stake. Four talks of French government representatives open and conclude the debates of the different round tables. (J.S.)

    Interplay between the dependence of symmetry energy on density and the variation of nucleonic densities across nuclear surface is discussed. That interplay gives rise to the mass dependence of the symmetry coefficient in an energy formula. Charge symmetry of the nuclear interactions allows to introduce isoscalar and isovector densities that are approximately independent of the magnitude of neutron-proton asymmetry. (author)

    1983-01-01

    The results of two quantitative scenarios balancing global energy supply with demand for the period 1980-2030 are reviewed briefly. The results suggest that during these 50 years there will be a persistent demand worldwide for liquid fuels, a continuing reliance on ever more expensive and ''dirty'' fossil fuels, and a limited penetration rate of nuclear generated electricity into the energy market. The paper therefore addresses a possible ''second'' grid driven by nuclear heat - a grid based not on electricity but on ''clean'' liquid fuels manufactured from gaseous and solid fossil fuels using nuclear power. Such a second grid would be an important complement to the electricity grid if the world is to progress towards a truly sustainable energy system after 2030

    Thank you for the opportunity to talk about the role of nuclear energy in the President's National Energy Strategy, particularly as it affects your discussions at this International Aging Research Information Conference. Dr. D. Allan Bromley, the President's Science Advisor, asked me to convey to you his interest in your work - he has had a long association with your field - and to express his determination to work to help assure that nuclear energy realizes its potential as a safe, clean source of a substantial portion of our electricity. Dr. Bromley also asked me to read a message to the Conferees assembled here today, and I will do so at the conclusion of my remarks. The National Energy Strategy, or NES, is now just over one year old, and it is rapidly being translated into action. For example, the President's budget request proposes investing over $1.1 billion in FY 1993 toward implementation of the NES, an increase of 39% over our expenditures in 1991, the year the NES was formulated. This budget will support a broad range of activities, including results-oriented R ampersand D on a broad range of energy technologies. The Senate has passed an energy bill containing many of the elements of the NES, and the House is expected to pass a similar bill. But the aspect of the strategy that I want to discuss today is its conclusion that nuclear energy will become an increasingly important component of our energy supply portfolio. The NES reflects the realization that nuclear power provides an attractive means of generating the electricity that will be needed to support our economic growth and consequent improvements in quality of life as we move into the next century

    In establishing of the nuclear fuel cycle in Japan that have a vulnerability in own energy structure, an effectiveness of energy security should be taken into account as well as an economy based on the balance of supply and demand of nuclear fuels. NMCC develops the 'Nuclear Energy Security Code' which was able to evaluate the effectiveness of energy security. Evaluation method adopted in this code is 'Import Premium' which was proposed in 'World Oil', EMF Report 6. The viewpoints of evaluation are as follows: 1. How much uranium fuel quantity can be reduced by using plutonium fuel? 2. How much a sudden rise of fuel cost can be absorbed by establishing the plutonium cycle beforehand the energy crisis?

    The uncertainties of growth in Croatian future energy, particularly electricity demand, together with growing environmental considerations and protection constraints, are such that Croatia needs to have flexibility to respond by having the option of expanding the nuclear sector. The paper deals with nuclear energy as an option for croatian sustainable economic development. The conclusion is that there is a necessity for extended use of nuclear energy in Croatia because most certainly nuclear energy can provide energy necessary to sustain progress. (author)

  3. Positioning of Nuclear in the Japanese Energy Mix

    International Nuclear Information System (INIS)

    Masuda, Tatsuo; Komiyama, Ryiochi

    2012-08-01

    Nuclear fission was discovered in the late 1930's. The first application went towards military use, and gradually expanded to civil use such as power generation. Power generation gained importance in two stages: firstly, to shift away from oil in power generation after the oil shocks in the 1970's, and second, to arrest climate change due to CO 2 -free nature of nuclear power more recently. This typically applies to Japan, which has become the world third largest in nuclear power generation. However, nuclear power is violent by nature, and major accidents of nuclear power plants shook the public confidence in nuclear safety. Japan has been put into such situation in a most radical way due to the Fukushima nuclear disaster of March 2011. This disaster may have its root causes in the history of nuclear development in Japan. Nuclear scientists failed to take the initiative in peaceful use of nuclear and lost the opportunity of making basic researches prior to the commercial introduction of nuclear power generation. Otherwise, safety issues could have been handled with greater care and 'nuclear safety myth' could not have prevailed. Today, the discussion is ongoing on how to position nuclear in the Japanese energy mix. Purely from economic viewpoint, due to the energy reality of Japan, it might be extremely difficult to sustain its economy without nuclear at least in short and medium term. However, the public opinions are divided with the vast majority in favor of zero-nuclear or decreased nuclear dependency. In this context, employing an energy-economic model, an attempt was made to analyze Japan's power generation mix in 2030 under possible nuclear scenarios and assessed the role of nuclear energy in its energy mix. A technical implication taken form this analysis is that, if intermittent renewables such as solar and wind may largely diffuse in power grid replacing nuclear power, output fluctuation from high penetration level of these energy sources will be

    The Faculty of Energy of the University 'Politecnica' in Bucharest is the only faculty in Romania in the field of nuclear energy education. With an experience of more than 29 years, the Faculty of Energy offers the major 'Nuclear Power Plants', which students graduate after a 5-year education as engineers in the Nuclear Power Plant major. Among the principal objectives of the development and reshape of the Romanian education system was mentioned the upgrading of organizational forms by introducing the transfer credit system, and starting in the fall '97 by accrediting Radioprotection and Nuclear Safety Master education. As a result of co-operation and assistance offered by TEMPUS-SENECA program, the new major is shaped and endowed with a modern curriculum harmonized with UE and IAEA requirements and a modern and performing laboratory. This way the Romanian higher education offers a fully correct and concordant structure with UE countries education. (authors)

  5. A roadmap for nuclear energy technology

    The prospects for the future use of nuclear energy worldwide can best be understood within the context of global population growth, urbanization, rising energy need and associated pollution concerns. As the world continues to urbanize, sustainable development challenges are expected to be concentrated in cities of the lower-middle-income countries where the pace of urbanization is fastest. As these countries continue their trajectory of economic development, their energy need will also outpace their population growth adding to the increased demand for electricity. OECD IEA's energy system deployment pathway foresees doubling of the current global nuclear capacity by 2050 to reduce the impact of rapid urbanization. The pending "retirement cliff" of the existing U.S. nuclear fleet, representing over 60 percent of the nation's emission-free electricity, also poses a large economic and environmental challenge. To meet the challenge, the U.S. DOE has developed the vision and strategy for development and deployment of advanced reactors. As part of that vision, the U.S. government pursues programs that aim to expand the use of nuclear power by supporting sustainability of the existing nuclear fleet, deploying new water-cooled large and small modular reactors to enable nuclear energy to help meet the energy security and climate change goals, conducting R&D for advanced reactor technologies with alternative coolants, and developing sustainable nuclear fuel cycle strategies. Since the current path relying heavily on water-cooled reactors and "once-through" fuel cycle is not sustainable, next generation nuclear energy systems under consideration aim for significant advances over existing and evolutionary water-cooled reactors. Among the spectrum of advanced reactor options, closed-fuel-cycle systems using reactors with fast-neutron spectrum to meet the sustainability goals offer the most attractive alternatives. However, unless the new public-private partnership models emerge

    Extrapolations contrast the future of nuclear energy use in Japan and the Republic of Korea (ROK) to that of the Association of Southeast Asian Nations (ASEAN). Japan can expect a gradual rise in the nuclear fraction of a nearly constant total energy use rate as the use of fossil fuels declines. ROK nuclear energy rises gradually with total energy use. ASEAN's total nuclear energy use rate can rapidly approach that of the ROK if Indonesia and Vietnam make their current nuclear energy targets by 2020, but experience elsewhere suggests that nuclear energy growth may be slower than planned. Extrapolations are based on econometric calibration to a utility optimization model of the impact of growth of population, gross domestic product, total energy use, and cumulative fossil carbon use. Fractions of total energy use from fluid fossil fuels, coal, water-driven electrical power production, nuclear energy, and wind and solar electric energy sources are fit to market fractions data. Where historical data is insufficient for extrapolation, plans for non-fossil energy are used as a guide. Extrapolations suggest much more U.S. nuclear energy and spent nuclear fuel generation than for the ROK and ASEAN until beyond the first half of the twenty-first century. (authors)

  7. The attitude to nuclear energy in comparison with other energy systems

    The subject of the study is the analysis of trends, the level and the determinants of the attitude to nuclear energy on the basis of survey data from representative samples. The emphasis is on analyzing the attitude to nuclear energy in the context of the so-called new political line of conflict. The most striking result of the trend analysis of the attitude to four energy systems - nuclear energy, coal, mineral oil, natural gas - was the drastic decline in the acceptance of nuclear energy in the time period covered by the available time series. The trends observed lead one to suppose that the evaluation of energy systems is no simple numbers game of the kind that means a more negative assessment of one energy system unavoidably leads to a more positive assessment of the other and vice versa, but that the individual energy systems are judged at least in part independently of one another. Effective public relations information and events may play an important part in changing attitudes to the individual energy systems. Structural factors are primarily a change in political values and an increased political competence on the part of the citizens. Both these factors taken together have created a greater perception of and sensitivity to the side-effects of the technical-industrial growth process. This aspect of the side-effects has been politicized by the New Social Movements particularly with reference to nuclear energy. Provided that political lines of conflict are important and lasting mechanisms for structuring, then nuclear energy will probably remain a constant theme, because of its importance in symbolizing fundamental problems at the technical-industrial growth process.

    Properties of nuclear magnetic resonance in the field acting on the nucleus in a ferromagnet were studied. Nuclei were {sup 57}Fe in iron and yttrium iron garnet. Static properties of resonance (frequency, line-width, dipolar structure) were investigated and compared with magnetic behavior and magnetic structure of the materials. Relaxation in garnet points out importance of long range fluctuations induced by impurities in a ferromagnetic lattice. (author) [French] Nous avons etudie les proprietes de la resonance nucleaire dans le champ existant a remplacement d'un noyau dans un corps ferromagnetique (champ local). Les noyaux etaient ceux de {sup 57}Fe dans le fer et dans le grenat d'yttrium et de fer. Les proprietes statiques de la resonance (frequence de resonance, largeur de la raie, structures dues a l'interaction dipolaire) ont ete etudiees et reliees aux caracteristiques magnetiques et a la structure de ces corps. La relaxation dans le grenat a mis en evidence les fluctuations a longue distance induites par des impuretes dans un reseau ferromagnetique. (auteur)

    Clean energies such as nuclear and solar are part of the solution to the energy dependence that we face today and also help us to reduce the greenhouse gas emissions, thus avoiding a global average temperature increase that is irreversible and harmful to all living beings on the planet. Independently the nuclear and solar energies have had a great development in recent years, so in this work we set ourselves the task of creating a synergy between them. First, we conducted a survey of different people involved in the area of energy (energy efficiency, clean energy and renewable sources) in order to know if the area of which they are part influences with respect to the impression that they have of safety in terms of supply, return on investment and safety to the health and environment of another energy source for which we use a correlation analysis. With the results obtained we propose to use photo thermic solar energy as a support to reduce the frequency of accidents by station blackout and we perform the analysis of the combination using the methodology of Probabilistic Analysis of Security with the help of SAPHIRE 7 software to realize the event trees by station blackout of a nuclear power plant and faults for a photo-thermal solar plant. Finally, the decrease in the probability of station blackout from the proposed combination is quantified. The results were favorable to indicate that the probability of station blackout is reduced in half and that is why is suggested to continue studying the combination. (Author)

  11. The Nuclear Energy Factor In Indian Politics

    Full Text Available Nuclear energy is a key branch of the world power system. The nuclear energy development is viewed by India as one of the ways to resolve the problem of the energy supply. In 2008 the country gained more opportunities for developing nuclear power sector and solving the national power deficit problem after NSG lifted restrictions on nuclear trade. This resulted in foreign companies emerging on the Indian nuclear market. In 2011 after the major emergency at Fukushima Daiichi Nuclear Power Plant in Japan India faced numerous anti-nuclear protests backed by NGOs, including those with foreign funding, and political parties. The article deals with the question of the political role this anti-nuclear opposition plays in India. According to some researchers the protests are organized by the competitors in order to compromise the business of a Russian company Rosatom in India. However, such demonstrations are spread throughout the country and directed against the competitors of Rosatom as well. The article comes to conclusion that the protests are just a reflection of the political fights in India where nuclear energy is a significant political factor.

    1 - Description of program or function: NMTC/JAM is an upgraded version of the code system NMTC/JAERI97. NMTC/JAERI97 simulates high energy nuclear reactions and nucleon-meson transport processes. It implements an intra-nuclear cascade model taking account of the in-medium nuclear effects and the pre-equilibrium calculation model based on the exciton one. For treating the nucleon transport process, the nucleon-nucleus cross sections are revised to those derived by the systematics of Pearlstein. Moreover, the level density parameter derived by Ignatyuk is included as a new option for particle evaporation calculation. A geometry package based on the Combinatorial Geometry with multi-array system and the importance sampling technique is implemented in the code. Tally function is also employed for obtaining such physical quantities as neutron energy spectra, heat deposition and nuclide yield without editing a history file. The code can simulate both the primary spallation reaction and the secondary particle transport in the intermediate energy region from 20 MeV to 3.5 GeV by the use of the Monte Carlo technique. The code has been employed in combination with the neutron-photon transport codes available to the energy region below 20 MeV for neutronics calculation of accelerator-based subcritical reactors, analyses of thick target spallation experimented and so on. 2 - Methods: High energy nuclear reactions induced by incident high energy protons, neutrons and pions are simulated with the Monte Carlo Method by the intra-nuclear nucleon-nucleon reaction probabilities based on an intra-nuclear nucleon cascade model followed by the particle evaporation including high energy fission process. Jet-Aa Microscopic transport model (JAM) is employed to simulate high energy nuclear reactions in the energy range of GeV. All reaction channels are taken into account in the JAM calculation. An intra-nuclear cascade model (ISOBAR code) taking account of the in-medium nuclear effects

    The International Organization for Standardization (ISO) has more than 200 Technical Committees that develop technical standards. During April 2004 took place in Buenos Aires the 14th Plenary of the ISO/TC 85 Nuclear Energy Committee. During this Plenary issues as Nuclear Terminology, Radiation Protection, Nuclear Fuels, Nuclear Reactors and Irradiation Dosimetry was dealt with. 105 International delegates and 45 National delegates (belonging to CNEA, ARN, NASA, INVAP, CONUAR, IONICS and other organizations) attended the meetings. During this meeting ISO/TC 85 changed its scope; the new scope of the Committee is 'Standardization in the fields of peaceful applications of nuclear energy and of the protection of individuals against all sources of ionizing radiations'. This work summarizes the most important advances and resolutions about the development of standards taken during this meeting as well as the main conclusions. (author) [es
