    International Nuclear Information System (INIS)

    importance of keeping the intellectual capital in the organizations that is to work with the knowledge from the collaborators. In Brazil still have many authors that discusses this concept and we adopt for this paper the definition form Cavalcanti where is the concept 'intellectual capital' refers either to the capacity, ability or experience, as well as to the formal education that the collaborators members have and add to the Organization. The 'intellectual capital' is an intangible asset, which belongs to the individual himself, thus it might be utilized by the organizations in order to generate value. The development and preservation of this intellectual capital is made through the implementation of forums of discussion, workshops or knowledge portals where the organization's collaborators share their experiences. Nevertheless, to assimilate and to develop the 'intellectual capital' does not add value to the organization: It is necessary to keep it. And one way to do so is to create desirable and encouraging work environments, to promote a sharing management and to offer programs of profits sharing. The objective of this paper is to describe how Brazilian Nuclear Energy Commission - CNEN has been developing a nuclear knowledge portal, focused in the Radiation and Safety Nuclear area. The Brazilian Nuclear Energy Commission (CNEN) is a federal autarchy created in October 10 of 1956, as a superior agency of planning, guiding, supervision and inspection in nuclear area being also the body entitled to establish standards and regulations on radiological protection, to issue licenses (permissions) and to survey and control the nuclear activities in Brazil. CNEN also develops researches related to the use of nuclear techniques in benefit of the society.

  1. Political Economy of Brazilian foreign policy: nuclear energy, trade, and Itaipu

    International Nuclear Information System (INIS)

    This dissertation advances an analytical framework intended to account for the international strategies of semi-peripheral countries: those industrialized Third World countries able to manufacture and export industrial goods. The empirical validation of the proposed framework was assessed through five case studies of Brazil's conduct in the following issue areas: nuclear energy, trade, and hydroelectric development of the Parana River Basin. A free-rider strategy was observed in the case of the nonproliferation regime. The decision to attain nuclear self sufficiency through the 1975 agreement with West Germany conforms to what was defined as unilateral behavior. Brazil's activism on behalf of Third World demands in North South negotiations as they impinge upon trade matters was accounted for in terms of the existence of private gains accruing from participation in that collective endeavor. Compliance with a regime's rules resulting from the use or threat of use of coercion was observed in the case of multilateral trade negotiations. The last case study examines a pattern of behavior defined as a hegemonic. In the development of a regime for the utilization of the Parana River Basin's hydroelectric potential, Brazil provided positive incentives to its junior partner (Paraguay) and negative inducements to the uncooperative partner (Argentina)

  16. Brazilian nuclear renaissance in a sustainable development scenario - 097

    International Nuclear Information System (INIS)

    Brazil generated 326 TWh of hydroelectric power in 2005, accounting for ∼81% of the electricity production for that year. The 2005 to 2030 projections for the Brazilian development indicate growths from 2,020 kWh to 4,380 kWh in the per capita electricity consumption and from US$4,300 to US$8,950 in the per capita GDP (in market exchange rate and 2005 US$). The consumption of electricity is to grow from 375 TWh in 2005 to 1,030 TWh in 2030. In simple view and without considerations of aspects related with energy efficiency, this growth means 1.8 times the generation capacity of the 20. century should be built along of 25 years of the 21. century. The Brazilian electricity generation will demand all primary sources to meet the foreseen growth of the electricity consumption. As economical, safe and clean primary energy source for electricity generation, the nuclear energy is one option capable of large-scale and short-term deployment in the Brazilian growth of the electricity consumption. The contribution of nuclear generation in the electricity consumption should evolve from the current 2.6% for amounts over 5% in 2030. The perspective of the Brazilian nuclear sector is evolving to be resumed and present an opportunity for pooling and rationalizing the available skills - technical, cultural and human. The role of business opportunities and the future demands in the value chain of nuclear activities are summarized in this document. Institutions of R and D and Brazilian universities play an important role for the formation of new demanded knowledge and human resources. (authors)

  17. Complex organizations: the case of the Brazilian nuclear sector

    International Nuclear Information System (INIS)

    The resumption of the Brazilian Nuclear Program (BNP), in the proposed size and after 20 years of paralysis, requires profound changes in the current organizational modeling of the national nuclear industry. The effectiveness of any process of organizational change is limited to three factors. The theoretical bottleneck happens when you do not know enough about a phenomenon in order to effect the desired changes. The resource bottleneck occurs when knowledge may be available to change people's behavior but the funds necessary for implementation may be lacking. The organizational bottleneck emerges when there are knowledge and resources to solve a problem, but may not able to organize the resources in order to carry out the problem-solving effort. In the case of resumption of BNP seems clear that there is the knowledge of what is needed to make policy and the intention to allocate the necessary resources. But the question is the following: the current organizational model of the Brazilian nuclear sector is consistent with the goals laid down in the scenario of resumption of BNP? That is, is there organizational ability to leverage a program of the size proposed for the nuclear area? Find answers to these questions is crucial, because the organizational model of the Brazilian nuclear sector consists of elements involving a complex interorganizational system. Thus, this article is to examine the appropriateness of the current organizational modeling of the Brazilian nuclear sector to current demands of society. As a result, the article aims to propose recommendations for a remodeling of the nuclear sector, taking into account the current national and international scenarios of nuclear energy. (author)

  19. Nuclear and Energy Research Institute (1956-2000). A case study under the science, technology and brazilian culture history

    International Nuclear Information System (INIS)

    We analysed a period of the contemporary Brazilian history with the aim to discuss the inter-relationship between science, technology (S and T) and culture in a developing country, showing as a background for a case of study the history of the 'Instituto de Pesquisas Energeticas e Nucleares'. The history of Science and Technology, as a result of the human brain ability of innovate using the resources offered by nature, it is not only the description of successive findings carried out by talented men. It is a reflex of determined age of history as a consequence of accumulated knowledge connected also to human and cultural relationships, which together leads to the scientific and technological progress. In fact, the human brain and society march along together and can not be separated in this journey. In our study we recovered the initial steps of IPEN's outbreak; inserted its achievements in the context of the national policy for nuclear technology and evaluated how this policy was a reply of the governmental organizations to the worldwide situation. Finally, we spread the scientific ideas and technological findings of this institution, who has translate much of the life style and culture of our society. For this purposes, we analysed internal technical report series elaborated by several researchers and few testimonies. The Institution developed the fuel cycle technology, supplied radioisotopes for medical diagnosis and treatment purposes, generating economic resources for our country. The nuclear techniques are a relevant tool for researchers of this Institution applied for several purposes, including the assessment of the radioactivity levels in the environment, radioprotection, etc. Besides those applications, other techniques including the laser technology, the fuel cell, corrosion studies, etc, were implemented as a result of the improved capabilities and skills acquired during the almost 50 years of the Institute's existence. We make evident two strong

  20. Planning the nuclear contribution to the Brazilian power programme

    International Nuclear Information System (INIS)

    Thermo-electric power in Brazil accounts for less than 20% of the total generating capacity. Brazil's power is essentially generated hydraulically, which ensures the growing development. The electric energy consumption keeps growing, with an annual average rate of 13% over the last five years. The present installed capacity is 20,000MW(e) and 185,000MW(e) are forecast for the year 2000. Most of the hydraulic resources are located in remote areas of the country very far from the consumption centres. In addition to the American-made nuclear power station under construction in Angra dos Reis with a power capacity of 626MW(e), the agreement signed in June 1975 between the Federal Republic of Germany and Brazil covers two more units, each of 1245MW(e) capacity, to be erected at the same site and planned to come into operation in 1982 and 1983. Several joint German-Brazilian companies will be established in the country for reactor and fuel manufacture. The Brazilian state holding nuclear company, Empresas Nucleares Brasileiras S A (Nuclebras), will participate in the formation of all joint companies with at least 51% of the capital investment. During the period of the agreement the Brazilian Government will encourage the development of technology and reduce the dependence on energy imports. Brazil's target is full independence in nuclear technology in about 15 years. (author)

  5. The Brazilian nuclear power manpower development programme

    International Nuclear Information System (INIS)

    Since the early stages of decision making, manpower availability has been recognized to be a key factor for the implementation of Brazil's nuclear power programme. Though care has been given to securing an industrial base and financial resources, the consequences of a lack of sufficient qualified manpower could be critical for the success of the whole programme. The broad scope of the Brazilian nuclear power programme which, as a main concept, aimed at establishing in the country a complete fuel cycle industry together with the construction of nuclear power plants, added another burden to the already complex task of providing appropriate human resources when advanced technologies are introduced in a developing country. Thus, not only the work-force required for nuclear power plant operation but also that needed for plant design, component manufacture, fuel cycle plant design and operation, had to be made available in number and qualification in accordance with the standards of the nuclear industry. The feasibility of the Brazilian programme depended on a complete transfer of technology, essentially achieved through personnel training. Again, the process of manpower preparation for an efficient know-how transfer required careful planning, and the great difficulty in its implementation was the lack of reliable experience at the time.

    2015-07-01

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP).

  11. Policies of industrial market and science and technology: the case of Brazilian nuclear program

    International Nuclear Information System (INIS)

    The relationship between policies and the definition of a national program of nuclear energy, is considered. The case under study is the Brazilian one. It is shown that an overall evaluation of market, industry and science and technology is mandatory for the definition of a nuclear energy program, and serious fault and hesitation, leading to contradiction and failure, have their roots in a basic lack of definition in policies. The evolution of the Brazilian Nuclear Energy Program will probably remain at a mediocre level until a definition at the level of policy-making in marketing, industry and science and technology is firmly pursued and maintained. (Author)

  12. The brazilian nuclear policy with respect to the public opinion

    International Nuclear Information System (INIS)

    Four decades of the Brazilian nuclear history have been analysed with special emphasis placed on government policy and its repercussion on public opinion. The implications of the new constitutional regulations which rule the issue are discussed. it is also studied the change in the nuclear program structure, enforced in August 1988. At different times, the government decisions on nuclear energy could be classified as miser, extravagant, dissimulated and frank, successively. Their aftermaths, which show little consistency with the expectations laid on them, have led to discredit by part of the society, which is controlled by a scientific - intellectual elite. However, recent successes are likely to reverse this trend, if the government explores them properly. (author)

  20. Nuclear policy retrospection in Brazil and forecasting for using of small nuclear power plants - SNPs - in the Brazilian electric system

    International Nuclear Information System (INIS)

    This thesis highlights the nuclear energy perspectives to regain a prominent place in the world energy mix, as a competitive and safe energy source. Just considering the current international changes in the nuclear power features in the developed countries, it is assessed the suitability and feasibility of defining a new nuclear policy in Brazil, based on the development of small and medium nuclear power reactors - SMNPR. The SMNPR's may be a good nuclear strategy for Brazil to develop a national and evolutionary reactor design with several improvements in safety, by means of passive safety systems. This reactor may play a significant role in the brazilian electrical system in the long term. (author)

  1. The Perspective of Small and Medium Size Nuclear Power Reactors in the Brazilian Isolated Electricity Grids

    International Nuclear Information System (INIS)

    As a consequence of the international crisis that has shaken the nuclear industry almost all over the world during the late 1980s, new academic contributions, which could settle a new basis for the nuclear energy in Brazil, have been scarce. This paper aims to partially fulfill this gap. We discuss some perspectives for the nuclear option to regain some prominence in the Brazilian energy matrix. Recent developments in the nuclear industry, including advances in plant design, have been opening interesting markets for small and medium nuclear power reactors (SMNPRs). We access the suitability and feasibility of such new technology in the Brazilian isolated electricity grids. We conclude by saying that, although the difficulties are still huge, SMNPRs may be a good strategy for Brazil to revitalize its nuclear policy. (author)

    Full Text Available Prospects for the wind energy market have proposed changes of focus to managerial issues. The objective of this article is to map the specific market factors from Brazilian wind energy industry, in order to develop reflections and considerations on the subject, towards to the managerial, strategic and commercial development of the sector. Through an exploratory methodology in empirical format, and by a SWOT analysis of Telescopic Observations Strategic Framework, were found results that show funding and grants determined by Brazilian government, as the big question of the wind energy industry marketing, allowing the economic viability of wind energy projects. Further, it appears that the wind energy industry is eager to investments and has great potential for new business, but there are problems within the producing companies which that have to be assessed, such as the competitiveness capability, the high equipment costs, the installation locations limitations and lack of specialized employees with specific skills and capacities.

  15. The role of the decomissioning process on the development of the Brazilian nuclear program

    International Nuclear Information System (INIS)

    The National Energy Plan 2030, issued by the Energy Research Company of the Brazilian Ministry of Mines and Energy (EPE, 2007), formalized a reference scenario for the renaissance of the nuclear option in Brazil. This scenario includes the completion of Angra 3 Nuclear Power Plant up to 2014 and the construction of four additional nuclear power plants of 1000 MWe: a fourth unit by 2020, a fifth unit by 2025 and the sixth and seventh plants by 2030. Worldwide, the energy demand and the renaissance of nuclear energy as a primary source for electric power generation are leading the industry toward new constructions as well as uprates and operational life extensions. In this new scenario the decommissioning is pushed further into the future and Brazil is not an exception, considering that Angra 1 NPP is under a process of uprating and certainly will apply for and will receive license renewals allowing its operation for 20 or more years beyond its original project. Thus, why to focus on decommissioning in the present? What is the importance of decommissioning for the development of the Brazilian nuclear industry considering the existing reactors? Should the decommissioning be considered in the design of the new nuclear power plants? What would be the decommissioning plan for the Brazilian Nuclear Power Plants? The present paper is intended to contextualize the decommissioning in the present scenarios as well as to try to answer the above questions. (author)

  19. Development of a model for strategic evaluation of the global performance of the Brazilian Nuclear Energy Commission

    International Nuclear Information System (INIS)

    A conscious, effective course of action, now essential to several areas and organizations, has become a must in the public administration. In this sense, modem managerial practices may contribute significantly for governmental organism to take up an attitude shifted to results in the society, without losing its eminently public function. In order to measure the social impact of the activities of the State as a whole, institutions must use mechanisms that allow self-evaluations of their performance, so as to verify the return obtained as a result of their efforts. However, most institutions do not have structured tools for such evaluation. The present study proposes to the Comissao Nacional de Energia Nuclear a model to measure its global performance, offering a proposed architecture for the measurement system in accordance with the results of the planning process of the Institution. The methodology presented also comprises the definition of cause-and-effect critical models between the strategic objectives of the organization and its respective factors critic ai for success, as well as related performance indicators. This work also includes the breakdown of the measurement system for the macro processes of the organization, optimizing resource sharing and the flow of information, avoiding redundant efforts and bringing forth further advantages aiming at creating a organizational 'unit'. Within this context, the developed model may offer substantial help for the improvement of the maturity of the organization in goal-oriented management, considering that the proposed global performance measurement follows a planned structure, with a systemic approach of the organization, allowing that the process be carried out in a way that is transparent and objective.

    Exploratory field research confirms the marketing administration philosophy in Nuclear Information Center (CIN) of National Commission of Nuclear Energy (CNEN), analyzing marketing activities referring to SONAR-INIS (current awareness) and SERVIR-INIS (provision of copies) promotion, in order to evaluate the impact of these activities relating to the use of the services by real users. The data collecting took place using a technique of documental analysis, semi-structured interviews with five managers of the Center, simple no-participant observation accomplished by the researcher in CIN, questionnaires about the administration philosophy applied to the managers, and questionnaires sent by mail to 176 users of the international sample. The 122 users'answers (69,31% of answers rate) were analyzed according to the statistical procedures of Statistical Package of Social Sciences (SPSS), with 0,05% of error margin, and 95% of confidence level. Nine assumptions of research were tested. It was concluded that: the first knowledge of the services was by circulars or letters; SONAR-INIS was not considered as the principal service by its information contents in order to develop professional activities by 60,5% of the users; SERVIR-INIS was considered the main service to access the documents related to the interest of 47,8% of the user; to the majority the most important reason to use both services was the convenience and facilities to access the services; suitability of interest was the most important criterion in order to accomplish the appropriate service; the CIN inquiry frequency to know about users' satisfaction level, their information interests, needs and expectation in order to adapt information offer to demand was irregular and seldom; CIN's concerns about knowing users' critics, complaints and suggestions was recognized by users; the majority of the users was interested in receiving information about the benefits of the services; the price of the copies obtained in

  5. Brazilian safety standard for fire protection in nuclear power plants

    International Nuclear Information System (INIS)

    During licensing and surveillance of nuclear power plants the Comissao Nacional de Energia Nuclear of Brazil adopted IAEA Safety Series No. 50-SG-D2 as the basic regulatory document for fire protection. In the Angra I nuclear power plant, which was designed in the United States of America, the BTP 9.5-1 guidelines (revision 2, including Appendix R to 10 CFR, Part 50) were used in support, and in Angra II, which was designed in the Federal Republic of Germany, several Federal German standards were adopted. Because these guidelines, and some of the requirements therein, do not always agree with Brazilian law and site characteristics, it was decided to produce Safety Standard NE-2.03. It is based on Safety Series No. 50-SG-D2 and BTP 9.5-1, since they contain specific approaches to fire protection in nuclear power plants. Where any disagreement with Federal German and Brazilian standards occurred, a comprehensive engineering analysis was made in order to solve these problems without compromising plant safety. All the relevant aspects of the Brazilian Safety Standard are outlined. Also discussed are the modifications which had to be made to the guidelines and their requirements so that they are in accordance with Brazilian law and the site characteristics. (author). 3 refs

  9. Binary breeder reactor: an option for Brazilian energy future

    International Nuclear Information System (INIS)

    To assure a continued supply of electric energy beyond a few decades from now, developmemnt of fast breeder reactors is a necessity. Binary fueled LMFBRs combine an improvement in the inherent safety of fast reactors and an efficient use of the abundant thorium. A nuclear system that starts with PWRs and gradually shifts to a FBR system or to a FBR-PWR symbiotic system appears to be the most reasonable one for Brazil. Natural uranium requirements and possible sequences of reactor introductions are discussed for some postulated Brazilian situations. A permanent system of approx. 100 GWe capacity can be established based on the estimated resource of natural uranium. (Author)

  11. Study of energetic balance in uranium cycle and in the nuclear Brazilian program

    International Nuclear Information System (INIS)

    The direct and indirect energetic investments for the construction and maintenance of nuclear power plants as well as for the fuel cycle, were analysed. The existing data in the literature was applied to the brazilian nuclear programme with a special attention to those peculiar aspects, particularly the enrichment process and mining. The energetic investments required by the various systems, using the 626 MW nuclear power stations or the 1240 MW, were determined in function of the brazilian ore with 0.108% of U3O8 and of a mine with a stripping ratio (the ratio of tons of overburden to tons of ore) of 28/1. About the enrichment, two hypothesis were considered for the concentration of 235U in the enrichment plant tails - the tails assay (0.25 and 0.35% of 235U) and for the specific energy consumption per unit of separative work (3.60 and 4.40 MWh/UTS). The fuel cycles with and without recycling of uranium and plutonium were taken in consideration. During the lifetime of the plants and for the various cases considered there is a self-consumption between 10 and 16 percent of the produced energy. The cumulative energy requirements as a function of time, was made for individual plants and for the brazilian nuclear programme as a whole in its actual form (9 nuclear power plants). (E.G.)

  14. Are the electric plans following the Brazilian energy policy?

    Energy Technology Data Exchange (ETDEWEB)

    Metri, Paulo, E-mail: pmetri@cnen.gov.br [Comissao Nacional de Energia Nuclear (CNEN-RJ), Rio de Janeiro, RJ (Brazil)

    2013-07-01

    The first article of Brazilian law 9.478, enacted in 1997, provides the main objectives for the country's energy policy. After this law came into force, all public and private investments bringing about increase in energy offers should comply with these objectives. The 1990's saw privatizations of major distribution companies as well as of some generation companies, stretching even into the 2000's. At the same time, the basic rules for the electric sector were also modified. The Government maintained its planning role in this sector. Law 10.847, enacted in 2004, sets forth the guidelines for the electric sector's activities. Since then, many rounds of bids have been conducted in order to meet increasing needs of generation and transmission. Now, almost ten years after the introduction of the new rules, some electric-generating plants and transmission lines have been built or are under construction. There is doubt whether these rounds will suffice in satisfying the original goals. Today, nuclear energy is produced exclusively by the State, and it seems that it will remain so for years to come. It is usual to hear that the nuclear energy does not participate in the natural competition existing in the planning stage, because this source is a State imposition. Nuclear plants are built in a pace that guarantees the maintenance of nuclear technology in the country. But nuclear energy has not been banned from electric planning. This planning must encompass all possible judgment criteria, so that the positive aspects of nuclear energy may also stand out. In this way, the objectives established by Law 9,478 may not comprise best judgment criteria. If the planning shows nuclear energy as an attractive alternative, it should not then be adopted as an obligation. (author)

  15. Considerations about the impact of the Convention on Nuclear Safety on the regulatory action of the CNEN in Brazilian nuclear power plants

    International Nuclear Information System (INIS)

    Preliminary discussion is conducted about the impact of the terms of the Convention on Nuclear safety, adopted by Diplomatic Conference in September 1994 in the International Atomic Energy Agency, on the regulatory action of Brazilian Nuclear Regulatory Body - CNEN. Following the Convention articles structure, the paper emphasizes technical aspects of the nuclear safety standards adopted in the licensing process of Brazilian Nuclear Power Plants. The recent experience in the issuance of Angra-1 NPP Permanent Operation Authorization is used to demonstrate that current safety standards in Brazil are in compliance with the international compromises and in agreement with what is expected by the so called Safety Culture.

  16. Brazilian nuclear politics in the context of contemporary international relations

    International Nuclear Information System (INIS)

    The present dissertation analyses the retaking of the debate over Brazilian nuclear Program's recovery by Luis Inacio Lula da Silva government, based on the defense of the utilization of an already acquired technology of its own to enrich uranium. In spite of the intrinsic duality on this subject and having in mind the pacific ends concerning the utilization of such technology by Brazil, the hypothesis sustained in this work is that the Program's defense is considered a strategy of sovereign international insertion with relative autonomy and an instrument of national valorization against other powers. In order to verify the hypothesis outlined above, we will analyse the actual government, comparing it to, two other moments in Brazilian History in which the nuclear issue also acquired preponderance on the national agenda, namely, Geisel and Sarney governments. Although these three moments differ in relation to their internal political regime, our goal is to identify their similarities. (author)

  17. Technicians for the Brazilian nuclear power programme

    International Nuclear Information System (INIS)

    The technician has a responsible role to fulfil in nuclear industry, acting as a bridge between the engineer and the skilled worker. Technicians must have sufficient theoretical knowledge to communicate with engineers, and a thorough understanding of technological practice; the nuclear industry demands both theory and practice of a high standard. In Brazil the essential role of the technician in industry is in general recognized. However, the lack of a nationally recognized Nuclear Technician and Nuclear Technologist qualification, as well as a desire of the best technicians to quality as engineers and, in some areas, inadequate salaries has resulted in a shortage of well-trained technicians. A first step to ensure availability of these technicians is to improve their career prospects and status through definition of appropriate career standards and salaries. Practical training by the industry can only be given in factories, plants and construction sites where nuclear work is done. It is proposed to extend apprentice training centres at three sites, to give the most promising students after two years of apprentice training two further years of instruction and practice to qualify as Nuclear Technicians. The training centres are chosen to cover the three sectors of nuclear industry where special training of technicians is important: manufacture and construction; operation and maintenance; and testing and analysis for process control and safety.

  20. The social construction of risk and the controversial Brazilian Nuclear Program: among scientific, political and public

    International Nuclear Information System (INIS)

    This research aims to investigate the Brazilian Nuclear Program (PNB) stating as reference the Fukushima nuclear accident. Its main purpose is to analyze how the Japanese accident impacted the PNB. Therefore, the program will be analyzed within 10-years (2004-2014) in order to answer this question. The discussion launched in this thesis is based on the framework of the Social Studies of Science and Technology, which enables the understanding of socio-technical controversies beyond the social or technological determinism. Through the discussion of the concepts of framing, socio-technical imaginary, risk and governance of science and technology, the research shows how the controversy in focus has resulted in the opportunity to consider not only economic, technological, environmental issues about nuclear energy, but also its political dimensions and challenges. Among these challenges, and from very different perspectives, arise questions about the role nuclear energy plays in the Brazilian context, the future of the program and the decision making process on these issues. Despite the central purpose of this study is essentially on risks, PNB and on the Brazilian context, it should be pointed that it is impossible to consider it in isolation of what is happening internationally (considering interests, tensions, relations between actors, etc.) The research thereby identifies key implications of Fukushima in the international context, but focuses on the disputes regarding possible review of the PNB. It also highlights how the socio-technical controversies, such as the nuclear energy, demand or impose a discussion on the governance of science and technology, risk and on the engagement of different sectors and actors in decision-making on issues, that are at the same time about energy, technology and nationality relevance. All this reflection is made from multi-sited analysis, which allowed following the controversy surrounding nuclear energy, reheated by the Fukushima

  3. Forecasting of the radioactive material transport demand for the Brazilian Nuclear Program and the security aspects

    International Nuclear Information System (INIS)

    In the nuclear fuel cycle, a lot of radioactive materials are produced. These radioactive materials must be transported in order to promote the integration of the fuel cycle units. Considerations about the transport characteristics of radioactive material were made for each section of the fuel cycle. These considerations were based on the experience of several countries and in accordance with the International Atomic Energy Agency regulations. A prediction of transport demands for the Brazilian Nuclear Program until year 2.010 was made. The prediction refers mainly to the quantity of radioactive material produced in each section of the cycle the quantity of vehicles needed for the transport of these materials. Several safety aspects were considered specially, the accidents predictions for years 2.000 and 2.010. The accident probability in Brazilian railroads and highways was compared with that of the USA.

    The main development vector of a society is the energy. The solar energy is the main energy source on the planet earth. Brazil is a tropical country, and the incident solar energy on its soil (15 trillion MWh/year) is 20,000 times its annual oil production. Several uses of solar energy are part of our lives in a so natural way that it despised in the consumption and use energy balance. In Brazil, solar energy is used directly in many activities and not accounted for in Energy Balance (BEN 2007), consisting of a virtual power generation. This work aims to make a preliminary assessment of solar energy used in different segments of the Brazilian economy. (author)

    The use of radioactive materials or nuclear phenomena in medicine begun before the Second World War; since then, the knowledge about nuclear power has been through a huge development. Impelled by the development of nuclear power plants, the application of nuclear techniques and processes in medicine also had a similar progress, as the same happened in Brazil. On the other hand, the parallel evolution did not happen in developing ways to guarantee the safe and secure use of such knowledge, which grew in the energy field faster and earlier than in medicine. This paper attempts to make a brief analysis of the progress in both fields throughout time, emphasizing the Brazilian Nuclear Program and its consequences on the field of medical physics. (author)

  16. Nuclear energy and nuclear weapons

    International Nuclear Information System (INIS)

    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

  18. Development of a quality management system for Brazilian nuclear installations

    International Nuclear Information System (INIS)

    The present work is a proposal for developing a quality management system for Brazilian nuclear installations, based on applicable standards. The standard ISO 9001:2000 [4] establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard IAEA 50-C/SG-Q [1] establishes general requirements for the implementation of a quality assurance system in nuclear installations. The standard CNEN-NN- 1.16 [5] establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The revision of standard IAEA 50-C/SG-Q [1], to be replaced by IAEA DS 338 [2] and IAEA DPP 349 [3], introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concept of 'Quality Assurance'. This approach is incorporated with the current tendency, because it guides the system to manage, in an integrated way, the requirements of quality, safety, health, environment, security and economics of the installation. The results of the characterization of the quality management systems established in the applicable standards are presented, with the determination of the common and conflicting points among them. Referring data to quality assurance program/quality management system in some nuclear installations of IAEA Member States are also presented. (author)

  2. Nuclear energy and energy security

    International Nuclear Information System (INIS)

    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

  9. Plutonium recycle in PWR reactors (Brazilian Nuclear Program)

    International Nuclear Information System (INIS)

    An evaluation is made of the material requirements of the nuclear fuel cycle with plutonium recycle. It starts from the calculation of a reference reactor and allows the evaluation of demand under two alternatives of nuclear fuel cycle for Pressurized Water Reactors (PWR): without plutonium recycle; and with plutonium recycle. Calculations of the reference reactor have been carried out with the CELL-CORE codes. For plutonium recycle, the concept of uranium and plutonium homogeneous mixture has been adopted, using self-produced plutonium at equilibrium, in order to get minimum neutronic perturbations in the reactor core. The refueling model studied in the reference reactor was the 'out-in' scheme with a constant number of changed fuel elements (approximately 1/3 of the core). Variations in the material requirements were studied considering changes in the installed nuclear capacity of PWR reactors, the capacity factor of these reactors, and the introduction of fast breeders. Recycling plutonium produced inside the system can reach economies of about 5%U3O8 and 6% separative work units if recycle is assumed only after the 5th operation cycle of the thermal reactors. The cumulative amount of fissile plutonium obtained by the Brazilian Nuclear Program of PWR reactors by 1991 should be sufficient for a fast breeder with the same capacity as Angra 2. For the proposed fast breeder programs, the fissile plutonium produced by thermal reactors is sufficient to supply fast breeder initial necessities. Howewer, U3O8 and SWU economy with recycle is not significant when the proposed fast breeder program is considered. (Author)

    2010-07-01

    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.

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.

  13. Fuel for the next Brazilian nuclear power plants

    International Nuclear Information System (INIS)

    The conclusion of the Angra III nuclear power plant ends a cycle of the nuclear energy in Brazil that started about forty years ago. Nowadays the country is planning the installation of 4 GWe to 8 GWe of nuclear power up to the year 2030. The nuclear reactors considered for this new cycle should take into account the current technologic development and environment of the nuclear market. They certainly will have significant differences in relation to the Angra I, II, and III reactors. Important impacts may result on the nuclear fuel production chain, e. g., case high temperature reactors were chosen, which can deliver electricity and heat. The differences between the fuels of the candidate reactors after Angra III are analyzed and development lines are suggested to minimize these impacts. (author)

  14. The challenge of energy poverty: Brazilian case study

    International Nuclear Information System (INIS)

    In recent years successive Brazilian governments have actively pursued economic and social policies aimed at reducing poverty and promoting social equality and inclusion. In the field of energy, this has meant introducing and implementing programs aimed at expanding the supply of safe and reliable energy to the poorest sectors of Brazilian society, including those living in remote rural areas. This paper draws attention on the findings of extensive field research to evaluate the impact of rural electrification on energy poverty in the context of government policies aimed at promoting energy equity. The authors re-examine the concept of an energy poverty line, seeking to fine tune its application to Brazilian social and economic realities, and then apply an analytical framework (Lorenz Curve, Gap Poverty, Gap Quadratic, Gini Coefficient and Sen Index) to evaluate the effectiveness of recent efforts in Brazil to expand access to electricity. One of the main conclusions of this study is that is that rural electrification leads to a significant reduction of the energy poverty level and a consequent improvement in energy equity. -Research highlights: → The access to electricity led to a marked change in the reality of the researched population. → Energy poverty and energy inequality were reduced significantly. → The strategy of combating energy poverty through programs of rural electrification is efficient.

  15. Farewell to the nuclear energy program

    International Nuclear Information System (INIS)

    In summer 1985 Brazil, presided over by Jose Sarney, definitely decided not to go on with the building preparations for Angra III, a third nuclear power plant, and to suspend the planning and projecting of Iguape I and II (Sao Paulo). In view of decisions such as these there is no doubt about the fact that the Brazilian government soon after entering upon its office attaches but secondary importance to the establishment and extension of a national nuclear power industry. The trend already revealed in its rudiments towards the end of the last Brazilian military government of Joao Figueiredo has meanwhile taken on its definite character and direction: financial cuts and retardation of the ambitious nuclear energy program initiated in the 70s with the aim of corroborating Brazil's position as a dynamic promising industrial nation and hegemonial power of the Latin American subcontinent.

  16. Management of disused sealed sources received by the Brazilian Center for Development of Nuclear Technology - CDTN, MG

    International Nuclear Information System (INIS)

    The increasing use of radioactive sources in Brazil brought as a consequence the increased number of disused sources because, after the withdrawal of the service, the sources are discarded by users of radioisotopes. These sources have been forwarded to the research institutes of the CNEN, among them CDTN - Brazilian Center for Development of Nuclear Technology -, who have received a significant amount of them, including more intense activity sources, such as from the teletherapy. For effective control of the sources, the compliance of the CNEN - Brazilian Nuclear Energy Commission - and the recommendations of IAEA -International Atomic Energy Agency - implemented a management system that enables the monitoring of the entire process, from the initial contact to the delivery of supplies to its appropriate packaging. This paper describes the progress that has been made

    Full Text Available Industrial energy efficiency has received increasing attention in many countries because of its importance in the pursuit of energy supply security, increased economic competitiveness and in the mitigation of greenhouse gases emissions. This paper aimed to evaluate the energy consumption development of the Brazilian pulp and paper industry through an energy decomposition analysis and an energy efficiency index approach over a 30 years period. An international comparison with other important paper-producing countries (i.e., Canada, United States of America, Finland and Sweden was carried out. It was concluded that despite a significant increase in the energy efficiency levels, responsible for 5.6 PJ savings in electricity consumption and for 38.6 PJ savings in fuels consumption between 1979 and 2009, a saving potential of 7.8 PJ and 146.2 PJ related to the annual consumption of electricity and fuels, respectively, could be identified in the Brazilian pulp and paper industry. Among the countries evolved in the international comparison, both the Swedish and Finnish industries were the most efficient, followed by the Brazilian, American and Canadian, the latter being the only one where there was a reduction in the energy efficiency levels from 1979 to 2009.

  1. Study of a brazilian cask and its installation for PWR spent nuclear fuel dry storage

    International Nuclear Information System (INIS)

    Spent nuclear fuel (SNF) is removed from the nuclear reactor after the depletion on efficiency in generating energy. After the withdrawal from the reactor core, the SNF is temporarily stored in pools at the same site of the reactor. At this time, the generated heat and the short and medium lived radioactive elements decay to levels that allow removing SNF from the pool and sending it to temporary dry storage. In that phase, the fuel needs to be safely and efficiently stored, and then, it can be retrieved in a future, or can be disposed as radioactive waste. The amount of spent fuel increases annually and, in the next years, will still increase more, because of the construction of new nuclear plants. Today, the number of new facilities back up to levels of the 1970's, since it is greater than the amount of decommissioning in old installations. As no final decision on the back-end of the nuclear fuel cycle is foreseen in the near future in Brazil, either to recover the SNF or to consider it as radioactive waste, this material has to be isolated in some type of storage model existing around the world. In the present study it is shown that dry SNF storage is the best option. A national cask model for SNF as well these casks storage installation are proposed. It is a multidisciplinary study in which the engineering conceptual task was developed and may be applied to national SNF removed from the Brazilian power reactors, to be safely stored for a long time until the Brazilian authorities will decide about the site for final disposal.

  3. Homogeneity study of enriched uranium dioxide to be used in intercomparison programs in the brazilian nuclear facilities

    International Nuclear Information System (INIS)

    The Brazilian nuclear facilities must dispose of measurement systems that allow the determination of their nuclear material inventories. The main goal of this work is the characterization of enriched uranium dioxide (UO2) pellets to use as test sample to evaluate and verify these systems through the participation of the involved laboratories in interlaboratorial comparison programs. The programs are formed by a network of specialized laboratories in determining materials of the nuclear fuel cycle. Therefore, before being sent to laboratories, the materials must have their homogeneity confirmed. The homogeneity study of the UO2 pellets has being carried out in the Safeguards Laboratory (LASAL) of Brazilian Nuclear Energy Commission (CNEN) through Destructives Analysis technique. The technique used was Davies and Gray/NBL titrimetric method. For this purpose, 25 pellets of enriched uranium dioxide from two different batches were randomly chosen. The model for homogeneity study between-unit variation (between-bottle homogeneity study) and minimum sample intake (within-bottle homogeneity study) adopted is a one-way ANOVA. No statistical significant differences were observed in the results of total uranium concentration for both batches. Thus, the UO2 pellets are considered homogeneous and can be used in a Brazilian measurement systems evaluation program.(author)

  5. Nuclear Energy General Objectives

    International Nuclear Information System (INIS)

    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

There was no disapproval, and the grade average of the students was 9.2, with the lowest grade 7.5 and the highest 10.0. In UTM, it was spent 9 days. 200 students were trained in 9 classes (an average of 22 students per class). Each class spent 9h of training, totaling 81 hours. There were 18 deprecations, due to the the lack of education of the students. The overall average of the grades was 8.8, with lower note zero and higher 10.0. In UTM 158 people were trained in 5 classes, with an average of 31 students per class.It is concluded that in classes with few students (7 to 12) there were few parallel discussions. In classes with many students (over thirty) there was a scattering of ideas, which interfered in the progress of training. As proposal for upcoming classes can be suggested an average 20 people per class. The division of classes in groups working together was beneficial, giving a unit, which allowed greater freedom in questions, increasing parallel content taught. The classes have evaluated positively the initiative of the work done, which will be extended to other units of DRM, and subsequently all of the INB - Brazilian Nuclear Industries

    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.

  13. Introduction to nuclear energy

    International Nuclear Information System (INIS)

    After some descriptions about atoms, fission and fusion, explanations are given about the functioning of a nuclear power plant. The safety with the different plans of emergency and factors that lead to a better nuclear safety are exposed, then comes a part for the environmental protection; the fuel cycle is tackled. Some historical aspects of nuclear energy finish this file. (N.C.)

  14. Nuclear energy and security

    International Nuclear Information System (INIS)

    Nuclear power is an important and, the authors believe, essential component of a secure nuclear future. Although nuclear fuel cycles create materials that have some potential for use in nuclear weapons, with appropriate fuel cycles, nuclear power could reduce rather than increase real proliferation risk worldwide. Future fuel cycles could be designed to avoid plutonium production, generate minimal amounts of plutonium in proliferation-resistant amounts or configurations, and/or transparently and efficiently consume plutonium already created. Furthermore, a strong and viable US nuclear infrastructure, of which nuclear power is a large element, is essential if the US is to maintain a leadership or even participatory role in defining the global nuclear infrastructure and controlling the proliferation of nuclear weapons. By focusing on new fuel cycles and new reactor technologies, it is possible to advantageously burn and reduce nuclear materials that could be used for nuclear weapons rather than increase and/or dispose of these materials. Thus, the authors suggest that planners for a secure nuclear future use technology to design an ideal future. In this future, nuclear power creates large amounts of virtually atmospherically clean energy while significantly lowering the threat of proliferation through the thoughtful use, physical security, and agreed-upon transparency of nuclear materials. The authors must develop options for policy makers that bring them as close as practical to this ideal. Just as Atoms for Peace became the ideal for the first nuclear century, they see a potential nuclear future that contributes significantly to power for peace and prosperity

  15. Energy-efficiency standards for electric motors in Brazilian industry

    International Nuclear Information System (INIS)

    The first regulation of the 'Energy Efficient Act' for electric motors, launched in 2002, established two sets of minimum efficiency performance standards (MEPS), for 'standard' (mandatory) and 'high efficiency' (voluntary) motors. An updated regulation, from the end of 2005 (Edict 553/2005), established the previous high-efficiency MEPS as mandatory for all motors in the Brazilian market. This paper analyses the consequences of this new regulation, which is foreseen to take effect in 2010. These new Brazilian MEPS are compatible with those implemented in other countries. The cost-benefit analysis, considered for different scenarios for industrial consumers, showed that motor substitution (from standard to high efficiency) is generally advantageous. A sample of nine thousand industrial motors has been used, with measured operation in actual conditions, to analyze the investment cost-benefit in three different scenarios. This analysis also demonstrated the benefit of motor substitution, with an average MWh cost from 20 to 35 US$, and with only a few substitutions presenting an unfavorable cost-benefit relationship to the user. We assess that Edict 553 avoided construction of 350 MW of hydroelectric capacity. Nevertheless, since the cost of conserved energy for this energy-saving measure is generally below the marginal cost of expansion of the Brazilian electric system, we propose mechanisms to share investment costs among the society as a whole, including demand-side bidding

  17. Nuclear Energy Data 2013

    International Nuclear Information System (INIS)

    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 declined in 2012 as a result of operational issues at some facilities and suspended operation at all but two reactors in Japan. Nuclear safety was further strengthened in 2012 following safety reviews prompted by the Fukushima Daiichi nuclear power plant accident. Governments committed to maintaining nuclear power in the energy mix pursued initiatives to increase nuclear generating capacity. In Turkey, plans were finalised for the construction of the first four reactors for commercial electricity production. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'Statlinks'. For each StatLink, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link

  19. Nuclear energy in Japan

    International Nuclear Information System (INIS)

    The contribution discusses the energy policy in Japan. In contrast to Germany nuclear power is not a bridging technology for Japan, the construction of new nuclear power plants is planned. The credibility of the Japanese nuclear power industry should have been discussed in the public even before the catastrophic reactor accidents in Fukushima-Daiichi. Safety, reliability, credibility and transparency are basic for public acceptance of high risk technologies. Up to 2011 Japan has not promoted the use of renewable energies.

  20. The Nuclear Symmetry Energy

    CERN Document Server

    Baldo, M

    2016-01-01

    The nuclear symmetry energy characterizes the variation of the binding energy as the neutron to proton ratio of a nuclear system is varied. This is one of the most important features of nuclear physics in general, since it is just related to the two component nature of the nuclear systems. As such it is one of the most relevant physical parameters that affect the physics of many phenomena and nuclear processes. This review paper presents a survey of the role and relevance of the nuclear symmetry energy in different fields of research and of the accuracy of its determination from the phenomenology and from the microscopic many-body theory. In recent years, a great interest was devoted not only to the Nuclear Matter symmetry energy at saturation density but also to its whole density dependence, which is an essential ingredient for our understanding of many phenomena. We analyze the nuclear symmetry energy in different realms of nuclear physics and astrophysics. In particular we consider the nuclear symmetry ene...

  1. Nuclear energy inquiries

    International Nuclear Information System (INIS)

    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

  3. Nuclear Energy Data - 2014

    International Nuclear Information System (INIS)

    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'.

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

  5. Nuclear energy today

    International Nuclear Information System (INIS)

    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)

  6. The nuclear energy debate

    International Nuclear Information System (INIS)

    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.

  7. Energy policy and regional inequalities in the Brazilian economy

    International Nuclear Information System (INIS)

    The objective of this paper is to evaluate the long-run regional impacts of the tariff policy of the Brazilian electric power sector. This sector has undergone a reform process that started in the 1990s. Since the beginning of the reform, two spatial trends of distribution of electric power tariffs have emerged among the Brazilian states, one of convergence and another of spatial divergence. These trends have been guided by the new electric power tariff policy and by the spatial features of the Brazilian economy, which is marked by a high degree of spatial concentration and hierarchical distribution of large markets. In addition, because of the presence of strong economies of scale, the recent electric power prices differentials might be caused by differentials in market size that provide better conditions for the achievement of economies of scale for electric power utility companies located in larger markets. Given the role of electric power as an important intermediate input in the production process and the interdependence between sectors, an Energy Interregional Computable General Equilibrium model was used to simulate the long-run regional impacts of electric power tariff policy in Brazil. The simulations showed that the heterogeneity of energy-intensity and the differentials of energy substitution drive the spatial impacts of changes in electric power prices. On the other hand, the recent trend of spatial dispersion of electric power prices might contribute to a decrease in the long-run economic growth and to an increase in the regional inequalities in Brazil. - Highlights: ► We model the regional impacts of tariff policy of the electric power sector in Brazil. ► High electric power tariffs increases in regions with higher electric-power-intensity. ► Heterogeneity of energy supply determines an unequal pattern of energy substitution. ► Low possibilities of energy substitution generate the most negative economic impacts

  10. Nuclear energy and jobs

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    The purpose of this article aims at verifying if according to the point of view of Final Energy Consumption in the agricultural sector, the Brazilian exports were beneficial to the country or not. Stimulated by a series of incentives it has been made a great effort with the purpose of mainly exporting primary products, and this effort may have been in conflict with the ever increasing indirect costs. And, it is in this point that there is the doubt as to the validity of energy consumption in the sector. (author)

  15. Axiology of nuclear energy

    International Nuclear Information System (INIS)

    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.

    2013-12-01

    The main goal of this work was to estimate the sensible (H) and latent (LE) heat flux using the eddy covariance method in a Cerrado "Campo Sujo" area, basically with herb-shrub physiognomy, sparse woody vegetation and approximately 2m height. The geographical position of the Cerrado, altitude, latitude, longitude, climate and weather conditions are determined by the dynamics of the atmosphere that affects the whole South America and consequently influence the ecological framework of ecosystems. The results shown by the components considered in the energy balance were more significant during the day, which the atmospheric boundary layer extends from the ground to about 50 or 100 meters height, showing greater instability and turbulence (u* > 0.2 m / s), and this turbulence is what justifies the use of the eddy covariance method to estimate the sensible and latent heat flux. The Cerrado presents seasonal difference between the densities estimates of sensible (H) and latent (LE) heat flux. During the rainy season the sensible heat flux (H) was 25% and the latent heat flux (LE) 54%. During the dry season the sensible heat flux (H) was 42% and the latent heat flux (LE) 30% of the energy budget.

  6. Nuclear energy in Armenia

    International Nuclear Information System (INIS)

    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)

It reviews the problems that must be faced in order to form a safe and practical energy policy with regard to health and the environment (potential hazards, biological effects and radiation dose norms), the proliferation of nuclear weapons, reactor accidents (including their causes, consequences and evacuation problems that arise), the fallout and contamination problems, and security (both reactor security and national security)

  9. Nuclear energy outlook 2008

    International Nuclear Information System (INIS)

    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

  10. The nuclear energy outlook

    International Nuclear Information System (INIS)

    In recent years, nuclear power has witnessed a remarkable revival, driven by a number of concerns about the current global energy mix. In a situation where use of fossil fuels predominates, energy security has become a priority for many countries, as prices remain volatile and the long-term prospect of their exhaustion looms large. Worries about climate change are also fostering interest in nuclear power given that this energy source is virtually free of CO2 emissions. The NEO concludes that nuclear energy is a mature technology that could play a large part in resolving the world's energy issues. Not only can nuclear power provide very large quantities of energy, largely CO2-free and for very long periods of time, but it can also be used to provide heat, to supply potable water and to produce hydrogen for transport. Nuclear energy is not necessarily the answer in all situations and in all societies. The NEO nevertheless aims to provide a lasting, quality resource to inform decision makers' and citizens' debates on potential energy options

  11. Nuclear Energy's Renaissance

    Kadak, Andrew C.

    2006-10-01

    Nuclear energy is about to enter its renaissance. After almost 30 years of new plant construction dormancy, utilities are seriously preparing for ordering new plants in the next two years. This resurgence in interest is based on improved plant performance, new Nuclear Regulatory Commission licensing processes, significant incentives introduced by Congress in the Energy Policy Act of 2005 to encourage new orders, and new technologies that are competitive, simpler to operate and safer. These new evolutionary light water reactors will pave the way to more advanced high temperature gas reactors such as the pebble bed or prismatic reactors that will provide improved efficiency and safety leading to more process heat applications in oil extraction or hydrogen production. The Next Generation Nuclear Plant (NGNP) also authorized by the Energy Policy act will provide the fundamental technical basis for the future of these technologies. Progress continues on the Yucca Mountain nuclear waste disposal site enabling this expansion. When coupled with the long term strategy of waste minimization through reprocessing and actinide destruction as proposed in the Global Nuclear Energy Partnership, the future of nuclear energy as part of this nation's energy mix appears to be assured.

  12. Nuclear energy debate

    The debate over the introduction of nuclear power in Australia has recently become more heated in light of safety concerns over the nuclear reactor meltdown emergency in Japan. Australia has also just committed to a carbon trading scheme to address its reliance on coal-fired energy and reduce greenhouse emissions. With 40% of the world's uranium located in Australia, the economic, environmental and health considerations are significant. This book contains an overview of global nuclear energy use and production, and presents a range of current opinions debating the pros and cons of Australia's

  13. High energy nuclear structures

    International Nuclear Information System (INIS)

    Nuclear field theory has been applied to study nuclear matter as well as finite nuclei. Within the mean field approximation the known bulk properties of nuclei such as binding energy, density, and compressibility are well reproduced. Charge and matter distributions of closed shell nuclei are in good agreement with experimental results, so are rms radii and single-particle energy levels. In addition to the description of known nuclear structure the field theoretical approach may reveal entirely new nuclear phenomena, based on the explicite treatment of mesonic degrees of freedom. The existence of such abnormal nuclear states was proposed by Lee and Wick employing the sigma-model Lagrangian. There the non-linearity of the meson field equations allows for soliton solutions in the presence of nucleons, in particular the sigma-field may exhibit a kink. Some of these solutions are considered

  14. Introducing the Brazilian program of technical support to the International Atomic Energy Agency - Department of Safeguards

    International Nuclear Information System (INIS)

    As an active Member State of the International Atomic Energy Agency (IAEA), Brazil has applied substantial resources in order to maintain the best possible cooperation with the Agency, aiming at a continuous improvement of the effectiveness and efficiency of the safeguards system. Over the last decades a number of projects, involving the participation of high-level Brazilian professionals in the nuclear area, have already been jointly completed. To continue providing this voluntary support to the IAEA Department of Safeguards for research, development and implementation, in 2006 Brazil decided to accept the IAEA's invitation to participate in the IAEA Member States Support Programmes initiative, which currently includes 21 Member States. The Research and Development (R and D) Programme for Nuclear Verification is the IAEA reference in this regard, establishing the high priority needs and describing each recognized departmental project. The Programme is issued every two years. The 'Brazilian Support Programme (BRZ SP)' was established on the basis of a set of administrative procedures titled 'Cooperation Arrangements and Guidelines', agreed between the Brazilian National Nuclear Energy Commission (CNEN) and the IAEA - Department of Safeguards. The scope of the BRZ SP includes: the participation in field tests and the evaluation of state-of-the-art technologies as requested by the IAEA for its safeguards applications; the training of safeguards personnel involved with safeguards implementation at both facility and State levels; laboratorial support in the area of destructive and nondestructive analysis of nuclear materials; the analysis of safeguards issues; information acquisition, analysis and evaluation; and the provision of human resources, such as experts and consultants to work directly with the IAEA Secretariat. The activities agreed under the BRZ SP are not restricted to CNEN staff members. Professionals from other Brazilian organizations may also be involved

  16. An option for the Brazilian nuclear project: necessity of fast breeder reactors and core design for an experimental fast reactor

    International Nuclear Information System (INIS)

    Aiming to assure the continued utilization of fission energy, the development of fast breeder reactors (FBRs) is a necessity. Binary fueled LMFBRs are proposed, as the best type for the Brazilian nuclear system in the future. The inherent safety characteristics are superior to current fast breeder reactors and an efficient utilization of thorium can be realized. The construction and operation of an experimental fast reactor is the first step and a basic tool for the development of FBRs technologies. A serie of core design for an 90 MW FBR is studied and the possible options and sizes of the main parameters are identified. (E.G.)

  19. Parliament and nuclear energy

    International Nuclear Information System (INIS)

    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)

    Full Text Available The aim of this study was to determine the energy requirements for maintenance (NEm and growth of 48 Brazilian Somali ram lambs with an average initial body weight of 13.47±1.76 kg. Eight animals were slaughtered at the trials beginning as a reference group to estimate the initial empty body weight (EBW and body composition. The remaining animals were assigned to a randomised block design with eight replications per block and five diets with increasing metabolisable energy content (4.93, 8.65, 9.41, 10.12 and 11.24 MJ/kg dry matter. The logarithm of heat production was regressed against metabolisable energy intake (MEI, and the NEm (kJ/kg0.75 EBW/day were estimated by extrapolation, when MEI was set at zero. The NEm was 239.77 kJ/kg0.75 EBW/day. The animal’s energy and EBW fat contents increased from 11.20 MJ/kg and 208.54 g/kg to 13.54 MJ/kg and 274.95 g/kg of EBW, respectively, as the BW increased from 13 to 28.70 kg. The net energy requirements for EBW gain increased from 13.79 to 16.72 MJ/kg EBW gain for body weights of 13 and 28.70 kg. Our study indicated the net energy requirements for maintenance in Brazilian Somali lambs were similar to the values commonly recommended by the United States’ nutritional system, but lower than the values recommended by Agricultural Research Council and Commonwealth Scientific and Industrial Research Organization. Net requirements for weight gain were less compared to the values commonly recommended by nutritional system of the United States.

  1. Nuclear Energy in Romania

    International Nuclear Information System (INIS)

    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

  2. The Brazilian nuclear industries - INB - in the field of the rare earth

    International Nuclear Information System (INIS)

    The Brazilian Nuclear Industries - INB is responsible for the execution of part of the cycle of uranium as nuclear reactor fuel for alternative energy generation. Soon INB shall increase the participation in this cycle, through the implantation of the line of powder and pastille. INB is also the successor of the monazite processing industries. The last one was NUCLEMON that was incorporated by INB. The connection of INB with this area is due to the presence of the strategic elements uranium and thorium in the monazite. The know-how was and continues to be developed by a chemical team of the National Commission of Nuclear Energy (CNEN) with the collaboration of the technical team of INB. The ever wider applications of the individual Rare Earth in the most different fields of the electrical, electronics, communication, optical, metallurgical, catalysis and other industries, as well as INB incessant inquire for the economical workability, brought INB to appraise the position regarding to the industrial production of the Rare Earth. The choice is bringing to the separation and commercialization of the individual elements and/or in groups containing a reduced number of Rare Earth, instead of the production and commercialization of the mixture of monazitic Rare Earth. This paper illustrates through quantitative information some aspects regarding to reserves, mining and physical separations of the monazite, as well as projections about INB resuming its industrial activities with insertion of technical improvements in both, the chemical treatment of the monazite and the Rare Earth separation. In this field, there will be presented in this paper the qualitative and quantitative results recently reached in a large dimension pilot plant. These results add to the technical conquest reached in the late years by the foregoers of INB, and that will be also presented. The paper contains also some appreciations regarding to the perspectives of INB's ingression in the field of

  4. Decision process regarding nuclear generation: the Brazilian case

    International Nuclear Information System (INIS)

    Countries face a constant need to expand their electricity generation capacities. Electricity sources in a country and the respective generation technologies have different technical, economic, environmental, social and political characteristics. The evaluation criteria of the generating sources and their technologies must not be restricted to the supply of the increased demand at the lowest cost. Compliance with other public policies must be considered in the decision process of the expansion, for instance, maximize local acquisition and minimize foreign fuel purchase. Countries have different energy resources, as well as different levels of technology and development in their industrial parks. Brazil has many mineral reserves, besides the hydraulic potential, for supporting the expansion. The decision process in this sector, which includes nuclear energy as a sub-sector, requires analyzing and evaluating various information and data. In this stage, a quantitative model providing a first approach for the decision may be applied. The new institutional structure adopted in the sector during the 1990s and 2000s brought about new conditions into an already complex decision process. In such context of methodology complexity, political aspects gain relevance, becoming of increased importance. The political environment is described and the players are identified. One conclusion and a few recommendations are provided. (author)

  6. 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.

  11. Nuclear energy and development

    International Nuclear Information System (INIS)

    Today, about 80 developing countries are using nuclear techniques in various sectors of their national economies. In the sector of industry, the radiation processing using gamma rays of high energy electrons has grown. While in the sector of health care, an estimated 10000 gamma cameras-imaging instruments are used in combination with radioisotopes in medical diagnosis. In the field of agriculture there is, nearly, 1000 crop varieties derived from radiaton-induced mutations which are grown worldwide. Furthermore and concerning the energy sector there is 417 nuclear power plants operating in 26 countries, accounting for just 16% of the world's total electricity production; the nuclear energy helped in developing and supporting a variety of sciences. 2 tabs

  12. Information and nuclear energy

    International Nuclear Information System (INIS)

    Comprehensive information on the safety aspects in the field of nuclear energy is supplied by the documents established by international and national bodies. As compared with chemical or biological hazards, the detection of radiations is especially simple and sensitive. The biological effects of ionizing radiation are well known thanks to epidemiological surveys and biological experiments. The dose-effect relationships have been determined allowing an assessment of the risks associated with any radiation exposure: natural exposure, X-ray in medical diagnosis, nuclear energy production,... A comparative study shows that the overall risks associated with the production of electric energy of nuclear origin are lower than those linked to fossil-fueled power plants, the latter being much lower than the risks from smoking

  13. Alternatives to nuclear energy

    International Nuclear Information System (INIS)

    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 106 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.

  14. The brazilian alcohol program in the national energy context

    International Nuclear Information System (INIS)

    The new national as well as international energy context demands revision of the Brazilian Alcohol Program. This revision should aim at the preservation of alcohol as an energy source while reducing subsidies. To this end a moratorium on new distilleries should be enforced till the middle of the next decade, accompanied by a policy focusing on cost reductions and improvements in productivity aimed at making alcohol competitive in the middle term, as well as a motor fuel policy which acts on demand and makes this moratorium viable while preserving the existing production structure. Concrete mechanisms to implement such a policy are proposed which segment the market for new vehicles and preserve the stability of alcohol and gasoline markets for existing vehicles. The effects of this policy were analyzed through simulation of 7 scenarios through the year 2005, which showed its feasibility; the continuation of the present policy, on the other hand, implies heavy additional subsidies.

  15. Nuclear energy and civilization

    International Nuclear Information System (INIS)

    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.

A reference conceptual design of a heavy-water-cooled and -moderated thorium converter reactor has been developed. The main features of that concept are the use of a prestressed-concrete pressure vessel, integrated arrangement of the primary circuit and the possibility of on-load fuel management. Economic competitiveness could be the result of high compactness, low capital costs and low fuel consumption. The technology involved is not very sophisticated; intensive engineering development work must be done in areas like fuel charge machine, concrete vessel insulation, and proper design of heat exchangers, but it is the feeling of the Group that these problems could be solved without seriously compromising the economic feasibility of the concept. Preliminary studies were made on the alternative use of enriched uranium or plutonium as a feed for the programme; in the latter case, plutonium could be produced in natural uranium reactors of the same type. The general conditions favouring each of these approaches to the thorium cycle have been determined, in particular those related to the costs of the fissile materials in the world market and to the country's policy related to nuclear fuel imports. The results of the preliminary studies are very encouraging and could justify the beginning of a research and development programme leading to the construction of a prototype in the 1970's. (author)

  5. Energy supply and nuclear energy

    International Nuclear Information System (INIS)

    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)

  6. The Brazilian experience in licensing Angra 2, a 'delayed' nuclear power plant

    International Nuclear Information System (INIS)

    The Brazilian nuclear power programme comprises two nuclear power plants in operation from different supplier countries. Furthermore, the second plant, Angra 2, had its construction started in 1976 and only recently in 2000 has achieved full power operation. This paper presents the experience of the Brazilian Regulatory Body in licensing this utility with all the complications arising from the different technologies, and safety philosophy, and the changes in safety standards, owners, suppliers, contractors and operators during the 25 years of construction. The paper presents first a history of the construction and commissioning of Angra 2, and then highlights some of the problems encountered in the licensing process. Some of the difficulties faced by CNEN due to several reorganizations and loss of personnel are also discussed. (author)

  7. Intermediate energy nuclear fission

    International Nuclear Information System (INIS)

    Nuclear fission has been investigated with the double-kinetic-energy method using silicon surface barrier detectors. Fragment energy correlation measurements have been made for U, Th and Bi with bremsstrahlung of 600 MeV maximum energy. Distributions of kinetic energy as a function of fragment mass are presented. The results are compared with earlier photofission data and in the case of bismuth, with calculations based on the liquid drop model. The binary fission process in U, Yb, Tb, Ce, La, Sb, Ag and Y induced by 600 MeV protons has been investigated yielding fission cross sections, fragment kinetic energies, angular correlations and mass distributions. Fission-spallation competition calculations are used to deduce values of macroscopic fission barrier heights and nuclear level density parameter values at deformations corresponding to the saddle point shapes. We find macroscopic fission barriers lower than those predicted by macroscopic theories. No indication is found of the Businaro Gallone limit expected to occur somewhere in the mass range A = 100 to A = 140. For Ce and La asymmetric mass distributions similar to those in the actinide region are found. A method is described for the analysis of angular correlations between complementary fission products. The description is mainly concerned with fission induced by medium-energy protons but is applicable also to other projectiles and energies. It is shown that the momentum and excitation energy distributions of cascade residuals leading to fission can be extracted. (Author)

    Several phylogeographic studies of seabirds have documented low genetic diversity that has been attributed to bottleneck events or individual capacity for dispersal. Few studies have been done in seabirds on the Brazilian coast and all have shown low genetic differentiation on a wide geographic scale. The Kelp Gull is a common species with a wide distribution in the Southern Hemisphere. In this study, we used mitochondrial and nuclear markers to examine the genetic variability of Kelp Gull po...

    International Nuclear Information System (INIS)

    The supply of Brazilian equipment and piping design for Angra 2 (and Angra 3 in some cases) have reached an advanced status in spite of the continuous outside difficulties which affect these nuclear power plants. The achieved quality is similar to the quality achieved in foreign countries and the nationalization program foreseen in 1975 is being largely surpassed. In this paper the actual situation is presented as well as the future perspectives. (Author)

  10. Nuclear energy and environment

    International Nuclear Information System (INIS)

    The demand for energy is very high in developed countries and is rapidly increasing in the developing countries. The supply of fossil fuels is limited and their use causes greenhouse effect and acid rain. Nuclear energy is an attractive option, as it does not cause these adverse effects. Very large amounts of oil, coal and gas have been saved in countries that have gone in for large scale nuclear energy. Releases of carbon dioxide which is a greenhouse gas and the oxides of nitrogen, which contribute to acid rain have been avoided in the process. However, the public is concerned about its other impacts on the environment, particularly of radioactive waste. The experts have shown that technology is available for safe disposal of radioactive wastes. Decommissioning has also been shown to be feasible. The radiological impact due to the release of radioactive materials from nuclear power plants is minimal. The dose due to these to the members of the public is too small to be measured. The estimated value of the radiation dose is a small fraction of the radiation dose due to natural background radiation present at all locations. The environment-friendly nature of nuclear power plants is getting due attention. (author)

    A conscious, effective course of action, now essential to several areas and organizations, has become a must in the public administration. In this sense, modem managerial practices may contribute significantly for governmental organism to take up an attitude shifted to results in the society, without losing its eminently public function. In order to measure the social impact of the activities of the State as a whole, institutions must use mechanisms that allow self-evaluations of their performance, so as to verify the return obtained as a result of their efforts. However, most institutions do not have structured tools for such evaluation. The present study proposes to the Comissao Nacional de Energia Nuclear a model to measure its global performance, offering a proposed architecture for the measurement system in accordance with the results of the planning process of the Institution. The methodology presented also comprises the definition of cause-and-effect critical models between the strategic objectives of the organization and its respective factors critic ai for success, as well as related performance indicators. This work also includes the breakdown of the measurement system for the macro processes of the organization, optimizing resource sharing and the flow of information, avoiding redundant efforts and bringing forth further advantages aiming at creating a organizational 'unit'. Within this context, the developed model may offer substantial help for the improvement of the maturity of the organization in goal-oriented management, considering that the proposed global performance measurement follows a planned structure, with a systemic approach of the organization, allowing that the process be carried out in a way that is transparent and objective.

  13. Non-nuclear energies

    International Nuclear Information System (INIS)

    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)

  18. French nuclear energy development strategy

    International Nuclear Information System (INIS)

    The nuclear energy development in France is based on the spirit of democracy. Through the discussions in various groups and so on, an energy independent policy has been decided. That is, the energy independence of 50% is aimed at by 1990, by reducing the energy import. In order to lower the current petroleum reliance from 48.5% to 32% (by 1990), the development of new energy sources, including nuclear power, is essential. Nuclear energy is particularly important for French energy independence. The nuclear energy development program is on a very large scale; the share of nuclear energy in the total primary energy will be from 26% to 28% by 1990. Nuclear power generation features its low cost, and its remarkably high safety. For the nuclear power development, the consensus by all people is necessary. For the purpose, the network of both local and central organs is set up. (Mori, K.)

  19. Nuclear energy and insurance

    International Nuclear Information System (INIS)

    It was the risk of contamination of ships from the Pacific atmospheric atomic bomb tests in the 1940's that seems first to have set insurers thinking that a limited amount of cover would be a practical possibility if not a commercially-attractive proposition. One Chapter of this book traces the early, hesitant steps towards the evolution of ''nuclear insurance'', as it is usually called; a term of convenience rather than exactitude because it seems to suggest an entirely new branch of insurance with a status of its own like that of Marine, Life or Motor insurance. Insurance in the field of nuclear energy is more correctly regarded as the application of the usual, well-established forms of cover to unusual kinds of industrial plant, materials and liabilities, characterised by the peculiar dangers of radioactivity which have no parallel among the common hazards of industry and commerce. It had, and still has, the feature that individual insurance underwriters are none too keen to look upon nuclear risks as a potential source of good business and profit. Only by joining together in Syndicates or Pools have the members of the national insurance markets been able to make proper provision for nuclear risks; only by close international collaboration among the national Pools have the insurers of the world been able to assemble adequate capacity - though still, even after thirty years, not sufficient to provide complete coverage for a large nuclear installation.

  3. The plutonium recycle for PWR reactors from brazilian nuclear program

    International Nuclear Information System (INIS)

    The purpose of this thesis is to evaluate the material requirements of the nuclear fuel cycle with plutonium recycle. The study starts with the calculation of a reference reactor and has flexibility to evaluate the demand under two alternatives of nuclear fuel cycle for Pressurized Water Reactors (PWR): Without plutonium recycle; and with plutonium recycle. Calculations of the reference reactor have been carried out with the CELL-CORE codes. Variations in the material requirements were studied considering changes in the installed nuclear capacity of PWR reactors, the capacity factor of these reactors, and the introduction of fast breeders. Recycling plutonium produced inside the system can reach economies of about 5% U3 O8 and 6% separative work units if recycle is assumed only after the fifth operation cycle of the thermal reactors.

  7. Nuclear Energy Economy

    International Nuclear Information System (INIS)

    A criterion of profitability for large capital expenditure is defined first. The methods for calculating depreciation are recalled and the discounted value system is described, so that the difference existing between estimated costs and present worth average costs, is correctly understood. Although the numerical values of costs are soon out of date, the numerical applications have been given in detail. All this provides a glimpse of the complex field of equipment programme selections as used with respect to electricity and nuclear electricity in particular. The economics of fissile substances are dealt with next: enriched uranium, plutonium about which it is shown that a market price does not make much sense at present. Finally the need to utilise nuclear and all other forms of energy in order to meet the requirements of mankind is highlighted. To do so, it is shown that in world terms and particularly in French terms, the energy requirements being what they are, how essential it is, in the short and medium term, to make use of nuclear energy and, within its framework, to have recourse to fast breeder reactors

  8. Nuclear energy in Malaysia

    International Nuclear Information System (INIS)

    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.)

  12. Brazilian nuclear power plants decommissioning plan for a multiple reactor site

    International Nuclear Information System (INIS)

    Actually, Brazil has two operating Nuclear Power Plants and a third one under construction, all at Central Nuclear Almirante Alvaro Alberto - CNAAA. To comply with regulatory aspects the power plants operator, Eletronuclear, must present to Brazilian Nuclear Regulatory Agency, CNEN, a decommissioning plan. Brazilian experience with decommissioning is limited because none of any nuclear reactor at the country was decommissioned. In literature, decommissioning process is well described despite few nuclear power reactors have been decommissioned around the world. Some different approach is desirable for multiple reactors sites, case of CNAAA site. During the decommissioning, a great amount of wastes will be produced and have to be properly managed. Particularly, the construction of Auxiliary Services on the site could be a good choice due to the possibility of reducing costs. The present work intends to present to the Eletronuclear some aspects of the decommissioning concept and decommissioning management, storage and disposal de wastes, based on the available literature, regulatory standards of CNEN and international experience as well as to suggest some solutions to be implemented at CNAAA site before starts the decommissioning project in order to maximize the benefits.

    International Nuclear Information System (INIS)

    To be able to solve its future tasks, space flight needs nuclear energy: manned space flight to the Mars is almost unthinkable without nuclear propulsion, and orbital nuclear power plants will be required for the power supply of high-capacity satellites or large space stations. Nuclear energy needs space flight: a nuclear power plant on the moon does not bother man because of the high natural radiation exposure existing there, and could contribute to terrestrial power supply.

    International Nuclear Information System (INIS)

    New nuclear power partly covers additional electricity demand and replaces retiring power plants in coming decades after 2010. Nuclear energy secures stable, economical and predictable electricity price as well as operation environment for the electricity intensive industry for coming decades. Nuclear energy also reduces the dependence on electricity import of Finland. Nuclear energy partly enables, together with renewable, fulfilment of Finland's Kyoto commitments. Solutions for nuclear waste management are a condition sine qua non for sound nuclear programmes. Funding has been arranged. All this is carried out in Finland in a transparent way and in accordance with any democratic requirements. (author)

  17. Nuclear energy and independence

    International Nuclear Information System (INIS)

    The pro-nuclear lobby in the United Kingdom won its battle. The Report on the Windscale Inquiry strongly endorsed the application by British Nuclear Fuels (a company owned by the government) to set up a plant to reprocess spent oxide fuels from thermal reactors; a motion in Parliament to postpone a decision was heavily defeated. The Windscale Inquiry was an attempt to settle in a civilized manner what has been tried in other countries by demonstrations and violence. In this exercise, a High Court Judge was given the task of assessing an enormous mass of highly complex technical and medical material, as well as economic, social, and political arguments. The outcome is bitterly disappointing to the objectors, all of whose arguments were rejected. Although the question of whether Britain should embark on a fast breeder reactor program was specifically excluded from the Inquiry, it clearly had a bearing on it. A decision not to proceed with the reprocessing plant would have made a fast breeder program impossible; indeed, the Report argues that such a decision would involve throwing away large indigenous energy resources, a manifest advocacy of the fast breeder. Other arguments for the decision to go ahead with the reprocessing plant included the need to keep the nuclear industry alive, and the profit which Britain will make in processing fuels from other countries, particularly Japan. The author comments further on present UK policy, taking a dissenting view, and then comments on the paper, Nuclear Energy and the Freedom of the West, by A.D. Sakharov

  18. Inevitability of nuclear energy

    International Nuclear Information System (INIS)

    The Indian atomic energy programme that has been launched in the late 1940s, with the courageous vision of Homi Bhabha, had made remarkable progress during the fifties, sixties and till the mid-seventies, leading to the establishment of a comprehensive base of nuclear science, technology and engineering, and the setting up of nuclear power stations. After the Pokharan experiment in 1974, the programme had to face a hostile attitude from the Western powers, with the stoppage of flow of technology and equipment from the West. The programme had shown the resilience to face the challenge, and march ahead, developing a range of indigenous capabilities both within the Department and in the Indian industry, though with a certain loss in the momentum. The successful design, construction and operation of the 100 Mw(t) research reactor Dhruva in Trombay, and the successful commissioning of the Fast Breeder Test Reactor in Kalpakkam, with a unique plutonium-uranium carbide fuel of Indian design, are significant capability demonstrations in the latter phase. On the power front, the twin-unit power stations at Narora (UP) and Kakrapar (Gujarat) have shown excellent performance, with respect to plant availability and capacity factor. This article presents an assessment of the progress achieved so far, amidst the difficulties encountered. Factors accounting for the apparently slow pace of growth are discussed, and the public concerns regarding nuclear safety and safety regulations are also addressed. In a situation where acute power shortages have become a fact of life, and difficulties can be foreseen in the development of coal and hydel resources (which are also limited in extent), the importance of pursuing the nuclear energy option is re-iterated. The need for unstinted government support to the program at this stage is also emphasized. (author)

  5. Ethics and Nuclear Energy

    International Nuclear Information System (INIS)

    Should the scientist be a morally unbiased person? This is the eternal question asked by many great thinkers interested in science. The answer is hard to find. Scientists are expected to take into consideration the consequences of their actions before they actually start ot act. Sometimes they have to make certain sacrifices in order to help mankind. Unfortunately, we are witnesses of some intelligent, but inhuman and selfish people carrying out their even most destructive ideas. In this paper the relation between scientists and experts in the field of nuclear energy and the public will be discussed. (author)

  7. Training of nuclear medicine technical staff by the Brazilian Society of Nuclear Medicine and Biology

    International Nuclear Information System (INIS)

    Full text: Nuclear medicine was introduced in Brazil in 1949, at the University of Sao Paulo. Despite being a pioneer in South America and the existence of about 280 clinics of this medical specialty in the whole country serving around 185 million inhabitants, there is not any dedicated course forming its technical staff. Another shortcoming lies in the fact that there are not any basic requirements established for these professionals by an official medical or nuclear entity. As result, one can find persons ranging from university graduates (biomedics, radiology technologists, biologists, pharmacists, chemists, physicists, etc.) to secondary school graduates or radiology technicians working in nuclear medicine centres, preparing patients, labelling and injecting radiopharmaceuticals, obtaining images and processing studies. Due to the high heterogeneity of the technical staff and lack of a formal preparation, the Brazilian Society of Nuclear Medicine and Biology (SBBMN) organized during 2004 and 2005 short courses conducted in different regions of Brazil in order to supply organized basic knowledge and practice on: 1. Quality control of 99Mo-99mTc eluates and labelling and checking of dose calibrators 2. Fundamentals of radiation protection, area monitoring and decontamination 3. Quality control of scintillation cameras. Six courses were given during these two years in four cities in the South Eastern region and two in the North Eastern region. The first two topics were delivered during one weekend and the participants were presented with a lecture in the morning and, in the afternoon, a hands-on practice on the same subject. As QC of eluates and labelling and checking of dose calibrators were less practised in most clinics, this was the first time that the majority of the participants performed these activities. In one course, offered during a national congress, all three topics were included and the practical part was replaced by many examples from routine

    Several phylogeographic studies of seabirds have documented low genetic diversity that has been attributed to bottleneck events or individual capacity for dispersal. Few studies have been done in seabirds on the Brazilian coast and all have shown low genetic differentiation on a wide geographic scale. The Kelp Gull is a common species with a wide distribution in the Southern Hemisphere. In this study, we used mitochondrial and nuclear markers to examine the genetic variability of Kelp Gull populations on the Brazilian coast and compared this variability with that of sub-Antarctic island populations of this species. Kelp Gulls showed extremely low genetic variability for mitochondrial markers (cytb and ATPase) and high diversity for a nuclear locus (intron 7 of the β-fibrinogen). The intraspecific evolutionary history of Kelp Gulls showed that the variability found in intron 7 of the β-fibrinogen gene was compatible with the variability expected under neutral evolution but suggested an increase in population size during the last 10,000 years. However, none of the markers revealed evidence of a bottleneck population. These findings indicate that the recent origin of Kelp Gulls is the main explanation for their nuclear diversity, although selective pressure on the mtDNA of this species cannot be discarded.

  16. Brazilian navy nuclear propulsion program catalytic of the national technological development

    International Nuclear Information System (INIS)

    The Naval Propulsion Development Program, leading by the Brazilian Navy, is one of the greatest self-sufficient technological efforts ever undertaken in Brazil. Besides the technological spin-offs, this program served as catalyst to maintain a critical mass of human resources, mainly in the 80's and early of 90's, when the destiny of the nuclear sector was uncertain. Today the R and D perspectives in Brazil are different, but this program is still updated with this new reality. This paper presents the main characteristics and the present status of this program.

    This research aims to investigate the Brazilian Nuclear Program (PNB) stating as reference the Fukushima nuclear accident. Its main purpose is to analyze how the Japanese accident impacted the PNB. Therefore, the program will be analyzed within 10-years (2004-2014) in order to answer this question. The discussion launched in this thesis is based on the framework of the Social Studies of Science and Technology, which enables the understanding of socio-technical controversies beyond the social or technological determinism. Through the discussion of the concepts of framing, socio-technical imaginary, risk and governance of science and technology, the research shows how the controversy in focus has resulted in the opportunity to consider not only economic, technological, environmental issues about nuclear energy, but also its political dimensions and challenges. Among these challenges, and from very different perspectives, arise questions about the role nuclear energy plays in the Brazilian context, the future of the program and the decision making process on these issues. Despite the central purpose of this study is essentially on risks, PNB and on the Brazilian context, it should be pointed that it is impossible to consider it in isolation of what is happening internationally (considering interests, tensions, relations between actors, etc.) The research thereby identifies key implications of Fukushima in the international context, but focuses on the disputes regarding possible review of the PNB. It also highlights how the socio-technical controversies, such as the nuclear energy, demand or impose a discussion on the governance of science and technology, risk and on the engagement of different sectors and actors in decision-making on issues, that are at the same time about energy, technology and nationality relevance. All this reflection is made from multi-sited analysis, which allowed following the controversy surrounding nuclear energy, reheated by the Fukushima

  2. Nuclear energy in the future

    International Nuclear Information System (INIS)

    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.)

  3. Climatic change and nuclear energy

    International Nuclear Information System (INIS)

    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.)

    What should a long-term energy policy strategy look like. Nuclear power is still a controversial issue. Can solar energy be a realistic alternative. The book presents a detailed comparison of the two energy sources, showing that a combined strategy of solar energy and energy conservation is better suited to the future ecological, social and economic needs than nuclear energy. Bauerschmidt's detailed investigation, in which the advantages and drawbacks of the two alternatives are carefully weighed against each other, makes it impossible for anybody to consider nuclear power as the only feasible alternative.

  6. Innovative nuclear energy systems roadmap

    International Nuclear Information System (INIS)

    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)

  7. Nuclear energy and environment: legal and institutional aspects in Brazil

    International Nuclear Information System (INIS)

    Environmental control and sanitary surveillance of nuclear and radiological activities are incumbent upon the Federal Union, the States, Federal District and the Municipalities in Brazil. The performance thereof falls under the Environmental National System (SISNAMA) and the Unified Health System (SUS) respectively. The Brazilian Nuclear Energy Commission (CNEN) controls the radiation protection and nuclear safety aspects of those activities. This paper analyses the division of competency on nuclear energy control as well as the necessity of harmonising the nuclear licensing proceedings with the environmental licensing proceedings, i.e., the ''Environmental Impact Assessment'' (EIA) and its respective ''Report on Environmental Impact'' (RIMA) provided for in the new Federal Brazilian Constitution. Public participation in the environmental control is also discussed as well as the constitutional and legal requirements for environmental protection applicable specifically to nuclear power plants. In the specific case of the final disposal repository for the radioactive waste generated from the radiological accident in Goiania, the procedures for its licensing are reported. (author)

    International Nuclear Information System (INIS)

    Status of the project: End of the project definition phase and preparation of the planned conceptual phase. Objective of the project: Development of processes for the utilization of nuclear process heat and/or nuclear process steam for the gasification of coal with high ash content, in particular coal from Brazil. Results: With the data of Brazilian coal of high ash content (mine Leao/ 43% ash in the mine-mouth quality, 20% ash after preparation) there have been worked out proposals for the mine planning and for a number of processes. On the basis of these proposals and under consideration of the main data specified by the Brazilian working group there have been choosen two processes and worked out in a conceptual design: 1) pressurized water reactor + LURGI-pressure gasifier/hydrogasification for the production of SNG and 2) high temperature reactor steam gasification for the production of town gas. The economic evaluation showed that the two processes are not substantially different in their cost efficiency and they are economical on a long-term basis. For more specific design work there has been planned the implementation of an experimental programme using the semi-technical plants 'hydrogasification' in Wesseling and 'steam gasification' in Essen as the conceptual phase.

  12. The manpower training and development programs of NUCLEBRAS for the Brazilian nuclear program

    International Nuclear Information System (INIS)

    As technology transfer is one of the main objectives of the Brazilian Nuclear Program, the principal aim of manpower training has been to provide the conditions for absorbing this technology. The strategy used for such a program required a quantitative and qualitative planning of manpower needs, through medium-range and long-term forecasts, with the condition of maximum utilization of the existing educational infra-structure. On-the-job training which is considered one of the most important means for technology transfer, was given highest priority. Also, management development was considered very important for the implementation of the Nuclear Program. This paper shows the results achieved from 1973 up to now by the manpower training and development programs. (Author)

  20. The energy efficiency of crude oil refining in Brazil: A Brazilian refinery plant case

    International Nuclear Information System (INIS)

    This article evaluates energy efficiency in Brazilian crude oil refining in comparison with the crude oil refining in the United States between 1930 and 2008. It aims to show that increased refinery complexity reduces the energy consumption of products of high value added. Moreover, the article shows that improvements in energy efficiency result in higher quality products and increased processing of oil. A Brazilian refinery with a capacity of 157,000 barrels per day (kbpd) was modernized in 2008 at a cost of US $1.3 billion. As a result, its capacity increased by 17%, from 157 to 189 kbpd. Its complexity index also rose from 3.2 to 6.8, allowing an improvement in the EII (energy intensity index) from 110% to 93%. In relation to the crude oil processed before being modernized, energy consumption fell from 0.75 to 0.52 MBtu (million British thermal units) per barrel processed. These proceedings show that increases in complexity reduce the energy consumed in the production of final products with high value added, such as gasoline, diesel and jet fuel. -- Highlights: → Increased refinery complexity reduces the energy consumption of products of high value added. → Improvements in refinery energy efficiency result in higher quality products and increased processing of oil. → Brazilian refineries were not affected significantly in the 2008 crisis, such as the US refineries, due to many factors. → The EII of Brazilian refining presents real opportunities for gains through changes in the profile of energy consumed.

  1. Nuclear energy and sustainable development

    International Nuclear Information System (INIS)

    Full text: To date, 370 GW of nuclear power capacity in operation around the world currently produce 16% of world's electricity, which represents the largest share provided by any non-greenhouse gas-emitting source. This results in a significant reduction of the environmental impact of today's electricity generation, and is set to continue doing so in the future. World Energy Outlook 2008 projections indicate an additional 250 GW of nuclear capacity by 2030, a scenario that would stabilise the atmosphere at 450 ppm CO2, thereby limiting global warming to 2 deg C above pre-industrial levels. However the road to long-term deployment of nuclear energy is still paved with numerous obstacles. The first one concerns fuel resources and fuel cycle backend: nuclear energy must become more sustainable in its utilisation of uranium ores, as well as in the management/disposal of nuclear waste. The second one is related to economics and safety issues: nuclear plants must be economically competitive, yet their safety levels must remain of key importance. Additionally, deployment of plants must be undertaken in a manner that can guarantee worldwide non-proliferation of nuclear weapons. Finally, they should help meet anticipated future needs for a broad range of products beyond electricity, such as high-quality process heat for industrial purposes. Generation IV nuclear energy systems are aimed at meeting these challenges by delivering unprecedented performance, thus ensuring nuclear energy's long-term expansion and sustained contribution to world's energy security

Present and potential contribution of nuclear energy to energy supply is developed. The pros and cons are given. In the second part is examined how the production and use of various form of energy including nuclear energy, can affect health and the environment, with special reference to waste of all kinds. Safety problems and risk of accidents are examined in both non nuclear and nuclear sectors. Prospects for a low energy society and economic and social implications of the use of new forms of energy are also discussed

  3. Finnish energy outlook - role of nuclear energy

    International Nuclear Information System (INIS)

    In this presentation author deals with production a consumption of electricity in the Finland. New nuclear power partly covers additional electricity demand and replaces retiring power plants in coming decades after 2010. Nuclear energy secures stable, economical and predictable electricity price as well as operation environment for the electricity intensive industry for coming decades. Nuclear energy also reduces the dependence on electricity import of Finland. Nuclear energy partly enables, together with renewable, fulfilment of Finland's Kyoto commitments. Solutions for nuclear waste management are a condition sine qua non for sound nuclear programmes. Funding has been arranged. All this is carried out in Finland in a transparent way and in accordance with any democratic requirements. (author)

  5. Nuclear energy: a vital energy choice

    International Nuclear Information System (INIS)

    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

  6. The future of nuclear energy

    International Nuclear Information System (INIS)

    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

    'Nuclear Energy - Meeting the Challenges' was the theme of the 25th Annual Conference of the Canadian Nuclear Society, held in Toronto, Ontario on June 6-9, 2004. The theme has the implication of optimism - that we WILL meet the many challenges needed to overcome if nuclear power is to play a significant role in our energy future. The organizers succeeded in presenting a thorough discussion of the challenges facing the nuclear power industry in Canada with close to 300 delegates attending the three-day event

  11. Nuclear Energy and European Union

    International Nuclear Information System (INIS)

    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.

    Cross-sectional and longitudinal studies present association of low dietary energy density with higher intake of vitamins, minerals and dietary fiber, lower intake of fat, and better balance of macronutrients. The objective of this study was to verify the relationship between dietary energy density and diet quality measured by an index of diet quality. This study used data from 496 adults and 445 older adults of cross-sectional population-based survey from São Paulo conducted in 2008-2009, Brazil. Dietary intake data was assessed by two 24-h dietary recalls. Dietary energy density values were calculated based on foods only method. Dietary energy density and revised Brazilian Health Eating Index and its components, were estimated by usual intake using Multiple Source Method. The relationship between dietary energy density and the total revised Brazilian Health Eating Index and its components were assessed by Gaussian family log-link model for each age group. The analyses showed an inverse association between dietary energy density and total revised Brazilian Health Eating Index in adults (T2:β = 0.96, p diet quality in Brazilian adults and older adults regardless of sex, per capita household income, body mass index, physical activity level, current smoking habits status, alcohol beverage drinking status and usual energy intake (kilocalories) from beverages.

  13. Future of nuclear energy research

    International Nuclear Information System (INIS)

    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

    While few people now believe that nuclear power would provide ‘power too cheap to meter’, there is still a common perception that nuclear power is a cheap source of electricity. The fact that nuclear power has not come to dominate electricity generation is seen as being due to a combination of public opposition and dealing with the safety issues raised by accidents such as those at Three Mile Island (1978), Chernobyl (1986) and Fukushima (2011). The reality is that nuclear power has seldom be...

  17. Intercomparison of 131I and 99mTc activity measurements in Brazilian nuclear medicine services

    International Nuclear Information System (INIS)

    This work outlines the quality assurance program for the activity measurements of the most used radionuclides at Brazilian Nuclear Medicine Services (NMS). The program aims to guarantee that the patient is given the correct prescribed amount of activity in diagnostic or therapeutic applications. This accurate administration depends upon proper use and calibration of the activity meters by the NMS. Underestimation of administered activity in diagnostic practices could delay correct diagnosis disturbing the value of the investigation. On the other hand, the overestimation would be worse, mainly in therapeutic applications, because an unnecessarily high absorbed dose would be delivered to the patient. The preliminary results of intercomparison for 131I and 99mTc showed that many activity meters used at NMS's present problems giving results up to 41% greater than the reference values determined at the National Metrology Laboratory for Ionizing Radiation (LNMRI) which is recognized as the Brazilian authorized metrology laboratory for ionizing radiation. These results have demonstrated that the NMS should improve the accuracy of the activity measurements of the radionuclides administered to the patients and establish the traceability to the national standards of measurements. These standards are based on a pressurized well-type ionization chamber installed at LNMRI and calibrated with reference sources standardized by absolute methods. The protocol of the intercomparison and recommendations made in order to minimize errors in measuring procedures are described and results are discussed

  18. Determination of 93Zr in medium and low level radioactive wastes from Brazilian nuclear power plants

    International Nuclear Information System (INIS)

    The majority of long-lived radionuclides produced in the nuclear power plants can be regarded as difficult-to-measure radionuclides (RDM), hence chemical separation is necessary before the nuclear measurement of them. The zirconium isotope 93Zr is a long-lived pure β-particle-emitting radionuclide produced from 235U fission and from neutron activation of the stable isotope 92Zr and thus occurring as one of the radionuclides found in nuclear reactors. Due to its long half-life, 93Zr is one of the radionuclides of interest for the performance of assessment studies of waste storage or disposal. Two different methodologies based on extractive resins and LSC and ICP-MS techniques that enables the 93Zr determination in medium (ILW) and low level (LLW) radioactive wastes samples from Brazilian nuclear power plants has been developed in our laboratory. Analyzing real samples 65% and 75% chemical yields for 93Zr recovery were achieved for ICP-MS and LSC techniques, respectively. The detection limits were 0.045 μg.L-1 for ICP-MS and 0.05 Bq.L-1 for LSC techniques. (author)

    2007-07-01

    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)

  10. Importance of the licensing process on the safety culture in the Brazilian nuclear fuel cycle facilities

    International Nuclear Information System (INIS)

    The main objective of the Nuclear Fuel Cycle Facilities licensing processes is to ensure the safety of these installations in their entire life cycle (in the installation site selection, designing, construction, pre-operational tests, operational and decommissioning phases). The Brazilian licensing process requires from the operator, among others, before the operating license: (I) a Site Report and a Final Safety Analysis Report, ensuring that all safety related issues are adequately analyzed and understood; (II) a formal structured Management System focused on the installation safety; and (III) dissemination of safety related information to all involved operator employees and subcontractors. Therefore, these requirements reflect in an adequate operator actions and practices, ensuring a working environment with a high level of safety culture. (author)

  11. Can we fix nuclear energy

    International Nuclear Information System (INIS)

    Dr. Weinberg discusses some of the history of various aspects of the nuclear industry in light of the accident at Three Mile Island. The siting of commercial nuclear power plants near population centers is a result of opening up nuclear operations at the private sector. Early reactors established as a part of the Manhattan Project were all remote from unknowledgeable populations. When the utilities began to construct nuclear plants, their siting tended to conform to the practices already established for generation plants. With the nearness of nuclear power plants to people, and with media coverage of accidents so widespread, the public perception of risk associated with nuclear energy deserves attention. The primary issue concerning nuclear power plants is, according to Dr. Weinberg, the 15 billion curies in an operating reactor and the possibility of their release. He identifies six characteristics necessary for an acceptable nuclear energy system: technical fixes; physical isolation; separation of generation and distribution; professionalization of the nuclear cadre; heightened security; and, perhaps most difficult, public education about the hazards of radiation. The major alternatives to fission - geothermal, fusion, fossil, and the various forms of solar energy - are discussed briefly

    International Nuclear Information System (INIS)

    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.)

  20. Religious organizations debate nuclear energy

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    Nuclear energy has distinctive merits (sustainable resources, low costs, no greenhouse gases) but its development must overcome serious hurdles (fear of accidents, radio-phobia, waste management). The large unit size of present-day reactors is compatible only with large electrical grids, and involves a high capital cost. Taking into account these different factors, the paper outlines how nuclear energy may contribute to the reduction of greenhouse gases, and which are the most promising developments. (author)

She examines some of the realities to be faced, and points out how important it is to anticipate and take necessary steps in order that difficulties, which are easily identifiable, may be reversed in the near future. The author also calls into question the means for reversal of the current situation, so as to satisfy the parties concerned: Brazil and her potential partners. Finally, the paper aims at complying with the conclusions reached by Working Group number 3 of the International Law Association on ''The Principles of Good Conduct in the International Nuclear Trade''.

  3. Nuclear Energy, Long Term Requirements

    International Nuclear Information System (INIS)

    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

  4. Evaluation of Heterogeneity Degree of U Compounds to be used in Intercomparison Programs in the Brazilian Nuclear Facilities

    International Nuclear Information System (INIS)

    The Brazilian nuclear facilities must dispose of measurement systems that allow the determination of their nuclear material inventories. The main goal of this work is the characterization of enriched uranium dioxide (UO2) pellets to use as secondary standard to evaluate and verify these systems through the participation of the involved laboratories in inter-laboratory comparison programs. The programs are formed by a network of specialized laboratories in determining the material the nuclear fuel cycle. Therefore, before being sent to laboratories, the materials must have their homogeneity certified. The technique used was Davies and Gray/NBL titrimetric method. No statistical significant differences were observed in the results of total U concentration for two different batches. Therefore, the UO2 pellets are considered homogeneous and can be used in an independent Brazilian measurement systems evaluation program. (authors)

    The nuclear symmetry energy at a given density measures the energy transferred in converting symmetric nuclear matter into the pure neutron matter. The density content of nuclear symmetry energy remains poorly constrained. Our recent results for the density content of the nuclear symmetry energy, around the saturation density, extracted using experimental data for accurately known nuclear masses, giant resonances and neutron-skin thickness in heavy nuclei are summarized.

  8. Argentine nuclear energy standardization activities

    International Nuclear Information System (INIS)

    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)

    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. Nuclear energy in Brazil energy context: alternatives of reactors and fuel cycles

    International Nuclear Information System (INIS)

    The effective utilization of nuclear power in Brazil was decided during the 80s and early 70s, when national and international perspectives indicated a possible lack of sufficient energy sources to support the development of the economy. Under these circumstances, decisions were taken that are still to be implemented. This thesis studies the conditions that conducted the brazilian nuclear sector to present situation and also, proposed alternative paths to the future of the sector as related to both nuclear reactors and fuel cycles. Evolution of the nuclear sector is focused considering the positions of different stake holders. It is shown that the nuclear sector developed independently from the objectives of the energy sector. Evolution of energy demand in Brazil is analyzed through evaluation of scenarios up to the year 2025. Importation of energy as well as indigenous energy sources are considered as competitors to nuclear power, which is considered as a viable supplier for electricity, industrial heat, desalination of water and commercial naval propulsion. A simplified life cycle analysis methodology is used to compare alternative options of reactors and fuel cycles. An offer model for the nuclear sector is developed in order to calculate the use of uranium reserves, the levelized direct and indirect costs, the costs of standardized plants and the overall radioactivity increase by different options of possible nuclear programs. This model is called OMNUS as an anagram for the Offer Model for the Nuclear Sector. (author)

Activities of international organizations includes energy planning activities of IAEA and OECD/NEA, introduction of the activities of FNCA, one of the cooperation mechanism among Asian countries. In addition, MESSAGE computer model was also introduced. The model is being developed by IAEA to effectively handle liberalization of electricity market combined with environmental constraints

  16. Britain's nuclear energy policy

    International Nuclear Information System (INIS)

    Full text: In the mid 1980s the Labour Party's position and clear intention was to phase out nuclear generated power in the UK. BNFL's reprocessing business was singled out for particular criticism. Many argued that this sounded the death knell for an industry with a legacy of negative public opinion and no commercial future. How against this background then was the Rt. Hon Tony Blair able, on 9 June 1999, to state that 'If we were to question the continued operation of Thorp, I think that would not be right. Thorp is an operation with orders now valued at some 12 billion pounds, it provides 6000 skilled jobs, it indirectly supports many more... I do not support the case of those who would like us to abandon Thorp?' Furthermore, in June 1999 the Royal Society stated that, 'it is vital to keep the nuclear option open' and in October of the same year the House of Commons Trade Industry Select Committee went further and advised, 'a formal presumption be made now for the purposes of long-term planning that new nuclear plant may be required in the course of the next two decades'. On 13 July 1999, the Secretary of State for Trade and Industry, Rt. Hon Stephen Byers, announced a possible sale of up to 49% of BNFL by a Public Private Partnership. Dare we view this as the genesis of a nuclear renaissance for the United Kingdom? This clear change in political attitude towards the nuclear option has come about as a result of a concerted public and government relations effort over the past ten years. That said, many barriers remain if we are to meet the challenge of delivering new nuclear build in the UK. Public opinion may allow new build but only if the industry demonstrates a track record of safety and environmental stewardship. There will always be the 'not in my back yard' argument so we must be a good neighbour and, most importantly of all, a long-term solution must be found for the disposal of nuclear waste. If the stage is set for the nuclear renaissance, the industry

  17. Nuclear energy: A female technology

    International Nuclear Information System (INIS)

    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.

  18. High education and nuclear energy

    International Nuclear Information System (INIS)

    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)

  19. Nuclear power: tomorrow's energy source

    International Nuclear Information System (INIS)

    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)

  20. Introduction - Latin America and nuclear energy

    International Nuclear Information System (INIS)

    For the second time in its history, the International Atomic Energy Agency is holding its General Conference in Latin America. The first was in Mexico City in September 1972; this September the Conference meets in Rio de Janeiro (in each case, the arrangement has been possible because of the very generous hospitality of the Host Government). Therefore, it is an appropriate occasion to devote a section of the IAEA Bulletin to nuclear energy in Latin America. The vast Latin American region presents many special opportunities for the introduction of nuclear science and technology. The first mission that the IAEA sent out, as far back as 1957, was to Latin America to promote co-operation in using radioisotope techniques. Today, these techniques are widely used by hospitals and medical research institutions throughout the region. Besides their medical applications, isotope techniques are also proving to be very useful in studying soils and irrigation, improving crops and livestock, and controlling insect pests. They also help make prudent use of the underground water resources in the region which, despite its bountiful rivers and tropical forests, includes many large arid areas. The major applications of nuclear technology have come only recently to Latin America, firstly in Argentina, where a 319 MW(e) nuclear power plant began operating at Atucha in 1974. It will soon be followed by the first Brazilian nuclear power plant - a 600 MW(e) light water plant at Angra dos Reis nearing completion. Argentina is building a second power plant at Embalse, and Brazil is planning two 1200 MW(e) plants at Angra and six more 1200 MW(e) units by 1990. Mexico is building its first nuclear plant at Laguna Verde, while other countries such as Chile and Colombia are planning the introduction of nuclear power. After a relatively slow start it, therefore, seems that nuclear power will go ahead fast in the Latin American region in the 1980's and 1990's. This is not surprising. Despite

  5. Patterns of energy use in the Brazilian economy: Can the profile of Brazilian exports determine the future energy efficiency of its industry?

    International Nuclear Information System (INIS)

    This study examines the integration of the Brazilian economy in the global economy as a determining factor for the energy efficiency of its industry. Depending upon the profile of a country's exports (i.e., depending upon the share of energy-intensive exports out of total exports), different quantities of energy are required to produce the country's exported goods, which may counterbalance efforts made elsewhere to improve the overall energy efficiency of the country's industry. Different scenarios for the energy embodied in the industrial exports of Brazil are considered for the period 1995--2015. These scenarios are a combination of different shares of energy-intensive goods in the total exports of the country with different assumptions for gains obtained in industrial energy efficiency over time. For all scenarios the same fundamental hypothesis of liberalization of commerce and economic growth are assumed. Results for the year 2015 show that the total energy embodied in industrial exports varies from 1,413 PJ to 2,491 PJ, and the total industrial use of energy varies from 3,858 PJ to 6,153 PJ, depending upon the assumptions made. This is equivalent to an average industrial energy intensity variation ranging from 13.8 MJ to 22.0 MJ per US$-1985. The authors conclude that any policy aimed at improving Brazil's overall industrial energy efficiency should concentrate not only on the reduction of the energy intensity of particular industrial sectors, but also (and, perhaps, more importantly) on rethinking the very strategy for the integration of the country's economy in the global market in the future, with respect to the share of energy-intensive goods out of total exports. The focus is not incidental, for the ongoing structural changes in Brazilian exports alone may come to offset any efficiency improvements achieved by the national industry as a whole

    This study developed a method to evaluate the evolution of energy intensity in the Brazilian industrial sector from 1995 to 2004. In order to do so, it was necessary to obtain six different measures (indicators) of the sector energy intensity. Considering the concept of energy intensity as the ratio between energy consumption and the level of economic activity, two measures were used for the energy consumption: a thermal (physical) and an economic one. For the level of economic activity, three measures were used: value of production, value of delivered goods and added value. In the Brazilian industrial sector, most of these indicators have behaved in a similar way. In a disaggregated way, energy intensity indicators show a unified direction of its evolution. However, a more elaborate study on the consumption profile of the Brazilian industrial sector and its economical activities indicates the presence of important deviations concerning the annual rate of change in energy intensity. Besides, there is no evident relation between these deviations and the composition of the different indicators of energy intensity. (author)

  7. From nuclear power to fusion nuclear energy

    International Nuclear Information System (INIS)

    The history of thermonuclear fusion, which is over 50 years long, now has come to a stage expected to pave the way to the industrial implementation of fusion energy. The euphoria, which has spread in the society after the success of thermonuclear arms' tests and first fission reactors, has also influenced plasma physicists, which then promised to launch fusion power plants within the next 20 years. However, the science development has shown once again, how cautiously such projections should be treated. Specialists have clearly underestimated the complexity of the task to create a fusion energy source for the Earth conditions. It took several decades of fundamental plasma process research to give birth to a new area of science-the hot plasma physics. Only thanks to the development of this discipline, parameters of fusion installations have gradually approached the diapason, which was of interest for a fusion power reactor. Today the plasma physics has enough theoretical and experimental achievements to transfer, from theory to practice, the issue of constructing the first fusion reactor, with power yielded from fusion reactions exceeding by an order of magnitude the energy spent for supporting the reactor plasma. Physicist have reasons to believe that the prospects of nuclear fusion energy (thermonuclear energy), which is called to eliminate the problem of limited energy resources, could become a reality in the second half of the XXI century

  8. September 11 and Nuclear Energy

    International Nuclear Information System (INIS)

    The terrible September 11 attacks have demonstrated the ability of international terrorists to carry out well-planned and complex operations that can kill thousands of citizens. The potential for biological, chemical and nuclear terrorism has increased and will remain as long as their underlying causes. Nuclear installations could be the targets, or the sources of materials usable for terrorism. Whilst thick containment buildings around nuclear reactors are unlikely to be breached, some installations, such as spent fuel pond are more vulnerable. The safety of nuclear installations must be reconsidered taking into account some new initiating events hitherto considered of very low probability. A resistance against nuclear power plant sabotage by terrorist group penetrating into reactor building, is a controversial topic. Measures against diversion of nuclear materials, which could be used in nuclear terrorism, must be reviewed. The danger of diversion from giant military stocks of highly enriched uranium and plutonium by far exceeds that from peaceful use of nuclear energy. Measures to neutralize these stocks, such as dilution of highly enriched uranium, should be speeded up and have a priority in public concern. As for the nuclear power stations, public should be informed about the recommendations of IAEA for better physical protection of nuclear materials prepared in 1999 (INFCIRC 225/Rev.4) and about Additional protocol to inadequate Convention on Physical Protection of Nuclear Materials from 1980, which is in a process of ratification. For acceptable nuclear future public must be aware that all required measures to eliminate unacceptable risks resulting from terrorist activity against nuclear installations will be undertaken.

  9. Energy supply without nuclear power

    International Nuclear Information System (INIS)

    In a first phase of work (1979-1980), the four energy paths were developed as an attempt to describe on a technical basis in quantitative terms, and combine in a consistent picture, the variety of opinions then prevailing in the Federal Republic with respect to future energy supply structures. The social compatibility of energy supply systems was the subject of investigation in the early eighties by two groups of scientists working on behalf, and following a suggestion, respectively, of the German Federal Ministry for Research and Technology, i.e., one group headed by K.M. Meyer-Abich and B. Schefold, and another group at the Juelich Nuclear Research Center. The final report by the Meyer-Abich/Schefold group, which was written for public release, is a book entitled 'Die Grenzen der Atomwirtschaft' (The Limits to the Nuclear Economy). This latter book came out in spring of 1986 and soon played a major role in the energy policy debate after the Chernobyl disaster. In their conclusions the authors clearly express themselves against using nuclear power on the grounds that it was a socially incompatible source of energy. This article compairs the energy scenarios K and S described in the book with the energy paths 2 and 3 of the Fact Finding Committee on Future Nuclear Energy Policy. (orig.)

  11. The Future of Nuclear Energy

    International Nuclear Information System (INIS)

    Current nuclear energy represents 23.5% of the total electrical power available within the OECD countries. This is the energy offering the lowest costs to generate, it does not emit greenhouse-effect fumes nor does it contribute to global warming, however, it does generate radioactive and toxic waste which society perceives as an unacceptable risk. For this reason the development of new nuclear installation in Europe is at a stand still or moving backward. Truthful information and social participation in decisions is the best way to achieve the eradication of the social phobia produced by this energy source. (Author)

  12. Hydrogen Production Using Nuclear Energy

    International Nuclear Information System (INIS)

    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

  13. Nuclear power and energy planning

    International Nuclear Information System (INIS)

    With the rapid depletion of conventional energy sources such as coal and oil and the growing world demand for energy the question of how to provide the extra energy needed in the future is addressed. Relevant facts and figures are presented. Coal and oil have disadvantages as their burning contributes to the greenhouse gases and they will become scarcer and more expensive. Renewable sources such as wind and wave power can supply some but not all future energy requirements. The case made for nuclear power is that it is the only source which offers the long term prospect of meeting the growing world energy demand whilst keeping energy costs close to present levels and which does not add to atmospheric pollution. Reassurance as to the safety of nuclear power plants and the safe disposal of radioactive wastes is given. (UK)

  14. The nuclear energy: a future energy

    International Nuclear Information System (INIS)

    The beginning of civil use of nuclear energy is resumed and the different steps of nuclear power utilization to produce electricity are given. The accelerations, the petroleum crisis in 1973, and the brakes such Chernobyl accident or Three Mile Island accident are explained. The competitiveness of nuclear power plants in front of fossil fuels power plants explains the stability of their utilization as well as the energy independence that they bring. The disadvantages remain the public opinion against a possible accident, the problem of nuclear waste storage and the privatization of electricity companies in a lot of countries where the investments favour the natural gas power plants because of the less expansive costs and the shorter payback period. In developing countries, nuclear power meets others obstacles. The financial difficulties and the debts of these countries reduce or declare void the advantages of nuclear electricity production and they do not always satisfy to the required technological competences. To fight against these obstacles, nuclear industry has to improve again the economic performances and to increase the safety and the environment protection to make the public reticence fall.

  16. The public and nuclear energy

    International Nuclear Information System (INIS)

    To explain why an individual or public opinion is for or against the peaceful uses of nuclear energy, one should not consider only the dimension of the risk involved, as experts on radiation protection and safety will often do. Many other dimensions should be considered, all the more as the nuclear problem is gaining importance on a national level, becoming the topic of the day in the press and other media and the subject of definite standpoints on the part of political parties and social groups. An investigation carried out by the Protection Division of the French Atomic Energy Commission has made it possible to specify the socio-cultural dimensions at the origin of the attitudes taken on the nuclear problem in France. The nuclear topic was therefore compared with other current topics of interest to public opinion; this comparison was made possible by means of an attitude survey covering various social groups. A model of social perception was thus developed. (author)

  18. Society response to nuclear energy

    International Nuclear Information System (INIS)

    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

    The economics of the civilian uses of nuclear energy, that is to say the economics of nuclear power generation in which its civilian uses has been virtually limited to power generation---has been the focus of much public discussion both internationally and domestically here in Japan. The reasons are that there are many underlying factors which determine the economics of power generation methods and that various assumptions can be made concerning these factors. In addition, the value of these ...

  4. How competitive is nuclear energy?

    International Nuclear Information System (INIS)

    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

  6. The Brazilian status on ADS R and D: Preliminary road map to a program on accelerator utilization on basic and applied nuclear physics, products and services and to drive an experimental neutron source sub critical facility

    International Nuclear Information System (INIS)

    Brazil, still a developing country, has an Industrial Nuclear Program, that although small has already achieved a good standard: two NPPs in operation, i.e., ANGRA I and II with 2 GW installed electric capacity are generating approximately 2% of the total installed electricity, a third unit under construction, a fuel cycle industry, INB, with the capability to provide fuel elements for the NPPs. The Brazilian Navy pursues a nuclear program for nuclear propulsion which includes all the front end of the fuel cycle, including the enrichment by ultracentrifuge that is being transferred also to the industrial sector (INB). Research and development is conducted by the various Research Institutes of the Brazilian Nuclear Energy Commission (CNEN): IPEN, CDTN, and IEN which have appropriate technical capability and facilities (research reactors and accelerators) to support the industrial nuclear program, provide products and services for the Brazilian society (e.g., radioisotopes), as well as to develop new technologies. It is fair to say, however, that the Brazilian research institutions do need some new challenges, mainly to motivate and to stimulate a new generation of young engineers and scientists to pursue careers in nuclear energy R and D. The Brazilian Nuclear Physics research, being pursued mainly by the Universities, has an outstanding standard. This is documented by the number of publications in international journals, scientific citations, the number and quality of scientists, and by its capability to form human resources (Ph.D. students). However, it is felt that this scientific potential, a few exceptions apart, still needs to transfer the benefits of the scientific knowledge to the Brazilian society. These boundary conditions call for a R and D program which identifies synergies, society needs, is in agreement with the international developments in science and technology, meets sustainability criteria, matches the Brazilian reality, provides an umbrella for

  7. Economic analysis of nuclear energy

    International Nuclear Information System (INIS)

    The objective of this study is to analyze how the economics of nuclear power generation are affected by the change in nuclear environmental factors and then, to suggest desirable policy directions to improve the efficiency of the use of nuclear energy resources in korea. This study focused to analyze the impact of the change in 3 major nuclear environmental factors in Korea on the economics of nuclear power generation. To do this, environmental external cost, nuclear R and fund, and carbon emission control according to UNFCCC were selected as the major factors. First of all, this study evaluated the impacts on the health and the environment of air pollutants emitted from coal power plant and nuclear power plant, two major electric power generating options in Korea. Then, the environmental external costs of those two options were estimated by transforming the health and environmental impact in to monetary values. To do this, AIRPACTS and 'Impacts of atmospheric release' model developed by IAEA were used. Secondly, the impact of nuclear R and D fund raised by the utility on the increment of nuclear power generating cost was evaluated. Then, the desirable size of the fund in Korea was suggested by taking into consideration the case of Japan. This study also analyzed the influences of the fund on the economics of nuclear power generation. Finally, the role of nuclear power under the carbon emission regulation was analyzed. To do this, the econometric model was developed and the impact of the regulation on the national economy was estimated. Further efforts were made to estimate the role by developing CGE model in order to improve the reliability of the results from the econometric model

  9. Nuclear energy from radioactive waste

    International Nuclear Information System (INIS)

    The global energy demand is increasing. Sound forecasts indicate that by the year 2020 almost eight thousand million people will be living on our planet, and generating their demand for energy will require conversion of about 20 thousand million tonnes of coal equivalents a year. Against this background scenario, a new concept for energy generation elaborated by nuclear scientists at CERN attracts particular interest. The concept describing a new nuclear energy source and technology intends to meet the following principal requirements: create a new energy source that can be exploited in compliance with extremely stringent safety requirements; reduce the amount of long-lived radioactive waste; substantially reduce the size of required radwaste repositories; use easily available natural fuels that will not need isotopic separation; prevent the risk of proliferation of radioactive materials; process and reduce unwanted actinides as are generated by the operation of current breeder reactors; achieve high efficiency both in terms of technology and economics.

  10. Nuclear energy release from fragmentation

    CERN Document Server

    Li, Cheng; Tsang, M B; Zhang, Feng-Shou

    2015-01-01

    Nuclear energy released by splitting Uranium and Thorium isotopes into two, three, four, up to eight fragments with nearly equal size are studied. We found that the energy released come from equally splitting the $^{235,238}$U and $^{230,232}$Th nuclei into to three fragments is largest. The statistical multifragmentation model is employed to calculate the probability of different breakup channels for the excited nuclei. Weighing the the probability distributions of fragments multiplicity at different excitation energies for the $^{238}$U nucleus, we found that an excitation energy between 1.2 and 2 MeV/u is optimal for the $^{235}$U, $^{238}$U, $^{230}$Th and $^{232}$Th nuclei to release nuclear energy of about 0.7-0.75 MeV/u.

  11. The Non-Proliferation Treaty of Nuclear Weapons (NPT) and the insertion of the Brazilian State in its regime

    International Nuclear Information System (INIS)

    The issue of nuclear weapons continues to appear as a focal point of International Relations. The efforts and concrete actions on disarmament, non-proliferation, and nuclear arms control are still issues that generate recurring tensions between States. However, in Brazil, there is little analysis of an academic nature about these issues and, with respect to current and prospective position of the Brazilian State in the Nuclear Weapons Non- Proliferation Regime, studies and analysis are even more scarce, or incipient. The present dissertation has as its object of study to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Regime arisen from NPT, and the Brazilian State insertion process in this Regime. Therefore our research work is structured in three areas: the first one is about the role of nuclear weapons in States security perception, the second is about NPT and its Regime, the third runs over the insertion of the Brazilian state in this regime. So, in summary, the research performed included the reasons that make a State to develop nuclear weapons, the NPT genesis and evolution of the perception of the meaning of that Treaty by the States, and the process and the degree of insertion of Brazil in the Nuclear Weapons Non- Proliferation Regime. The inquiry sought to place this object of study in the broader debate on Foreign Relations, based on the approaches of the discipline devoted to the question of managing the security of States, id est, the two approaches that constitute the mainstream of the discipline: the perspective theoretical liberal (and neoliberal variants) and realistic thinking (and neo-realist). Thus, we have used different theoretical lenses, which we think necessary for understanding the specific parts and causal connections between these parts of a complex issue. (author)

    The author compares the per capita power consumption of Kenya with that of some more developed countries and makes a plea for the greater utilization of nuclear power to augment natural resources in the developing world. He considers nuclear energy first for its educational uses and then for its commercial and industrial uses. With reference to the requirements of Kenya, the questions of costs and economic reactor size are discussed. The author insists that unless Africa makes use of the immense resources offered by atomic energy, the continent will be limited to an extremely slow development, incompatible with the needs of present-day man.

    The regimes of accountability, the organizations of global governance and institutional arrangements of global governance of nuclear non-proliferation and of Mutual Vigilance Brazilian-Argentine of Nuclear Safeguards are the subject of research. The starting point is the importance of the institutional model of global governance for the effective control of non-proliferation of nuclear weapons. In this context, the research investigates how to structure the current arrangements of the international nuclear non-proliferation and what is the performance of model Mutual Vigilance Brazilian-Argentine of Nuclear Safeguards in relation to accountability regimes of global governance. For that, was searched the current literature of three theoretical dimensions: accountability, global governance and global governance organizations. In relation to the research method was used the case study and the treatment technique of data the analysis of content. The results allowed: to establish an evaluation model based on accountability mechanisms; to assess how behaves the model Mutual Vigilance Brazilian-Argentine Nuclear Safeguards front of the proposed accountability regime; and to measure the degree to which regional arrangements that work with systems of global governance can strengthen these international systems.

    The 'Plan Energetico Nacional de 1983' (1983 National Energy Program)(PEN-83) was approved recently by the Spanish Government and presented to the 'Cortes Espanolas' (Spanish Parliament) in May 1984. The PEN-83 is being discussed at present in the Parliament and it is possible that some modifications be introduced, but expectedly will be rather limited and minor. PEN-83 covers the period 1983-1992. It includes a comparative analysis of the evolution and situation in OECD countries and in Spain. In Spain the offer, supply and consumption of primary energy and of the interrelation with other economic indicators, such as the gross domestic product, inflation rate and unemployment compared with that of the industrialized OECD countries, has shown a much lower capability to adapt its structure to the energy price increases

  4. Nuclear Energy Today - Second edition

    International Nuclear Information System (INIS)

    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

  5. Nuclear energy and the media

    International Nuclear Information System (INIS)

    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

  7. Nuclear energy and process heating

    International Nuclear Information System (INIS)

    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

  15. Public communication and nuclear energy

    International Nuclear Information System (INIS)

    The article tries to explain why on occasion the public's perception of nuclear is more negative than of any other form of electricity generation or issue related to this field, when in reality public opinion has been gradually losing interest in nuclear in recent years. In fact, we could say that as nuclear loses its interest, its presence in the media grows in relation to the environmental aspects of electricity generation, of which nuclear form a part. Of the accusations directed at the nuclear industry, probably the most frequent one concerns the lack of transparency and lack of information on its activities. This article shows how the nuclear sector is probably one that generates more and better information on its own business. However, the lack of social acceptance of this activity, and of the energy business in general, is recognized. To solve this, mention is made of the example of France and Finland, where a well planned communication policy, implemented on a sustained basis over time, and the invitation to society to take part in these issues have favored a substantial improvement of public acceptance of electric generation sources, and specifically the nuclear option. The article ends with some recommendations that could be applied to Spain. (Author)

    This study identified the role of nuclear energy in the following three major aspects. First of all, this study carried out cost effectiveness of nuclear as a CDM technology, which is one of means of GHG emission reduction in UNFCCC. Secondly, environmental externalities caused by air pollutants emitted by power options were estimated. The 'observed market behaviour' method and 'responses to hypothetical market' method were used to estimate objectively the environmental external costs by electric source, respectively. Finally, the role of nuclear power in securing electricity supply in a liberalized electricity market was analyzed. This study made efforts to investigate whether nuclear power generation with high investment cost could be favored in a liberalized market by using 'option value' analysis of investments.

    International Nuclear Information System (INIS)

    The Nuclear Energy Institute (NEI) provided a brief presentation on the state of energy demand in the United States and discussed the improving economics for new nuclear power plants. He discussed the consolidation of companies under deregulation and the ability of these larger companies to undertake large capital projects such as nuclear power plant construction. He discussed efforts under way to support a new generation of plants but noted that there needs to be greater certainty in the licensing process. He discussed infrastructure challenges in terms of people, hardware, and services to support new and current plants. He stated that there needs to be fair and equitable licensing fees and decommissioning funding assurance for innovative modular designs such as the PBMR. He concluded that NRC challenges will include resolving 10 CFR Part 52 implementation issues, establishing an efficient and predictable process for siting, COL permits and inspection, and an increasing regulatory workload

    The silence has been kept too long. Nuclear energy has to implement some strong communication strategies in order to firstly attract the most valuable employees, and secondly to develop on the long term. The paper presents arguments and means for the nuclear energy companies to communicate on the inside and the outside of their organizations. Firstly, the internal communication of a nuclear power plant organization is as important as completing it's object of activity, it is a basic element for a strong image of the company and of the industry on the outside. If (executive) employees acknowledge the importance of the company and industry they work for, surely this message will be supported by external parties as well. Employees do not simply work in an office like theirs, but for a nuclear plant and they should become the first exponents of the industry, with respect to the theory that every employee is a marketer of their business. In order to accomplish this, a strong organization has to be built and healthy work environment has to be put into place. The most time and cost efficient methods, in order to attain high group adherence of the employees are group-ware applications, developed on an intranet platform, inside the company. Another means of motivation of the present and future employees are interactive exchange programs between companies from different countries. An issue that stands in the way of opening the way to communicate with the public is the degree of technicality implied by the energy industry, in particular the nuclear sector. Secondly, the external communication of such a company may solve - on the long term - the current personnel crisis in the Nuclear Energy sector, if targeted toward this direction. An external communication strategy would raise the level of public acceptance regarding the nuclear energy. One of the means of putting it into practice would have to be: internships for students, in order to allow young people to test being

    The Standing Committee on Energy, Mines and Resources of the House of Commons of Canada undertook a study of the economics of nuclear power in Canada. This is its report on the evidence it heard. It found that maintaining the nuclear power option is vital to Canada's interests. The Committee recommended that: the schedule for establishing a commercial high-level radioactive waste repository be advanced; the basic insurance coverage on nuclear facilities be raised; the federal government increase its financial support of Atomic Energy of Canada Ltd. (AECL); AECL expand its research and development activities, including non-nuclear R and D; AECL be allowed to hold a minority interest in any component of AECL that is privatized; any new entity created by privatization from AECL be required to remain under Canadian control; the Atomic Energy Control Act be altered to allow the Atomic Energy Control Board (AECB) to recover costs through licensing fees and user charges, while the AECB's parliamentary appropriation is increased to offset remaining costs of operations; membership on the AECB be increased from one to five full-time members, retaining the present four part-time members; the AECB hold its hearings in public; the name of the AECB be changed so it is more readily distinguishable from AECL; the AECB establish an office of public information; and that federal and provincial governments cooperate more closely to identify opportunities where more efficient use of electricity could be achieved and to promote those measures that can attain the greatest economic efficiency

  4. Public awareness of nuclear energy

    International Nuclear Information System (INIS)

    Many countries in the world are in the process of getting acquainted with nuclear power nowadays. As in all structural changes nuclear power option leads to various discussions with a reason or not. The public has certain reasonable worries related to problem brought by the TMI and Chernobyl Nuclear Power Accidents. The disasters caused by atomic bombs and these three accidents affected the people in a very adverse manner. Meeting energy demand is of high importance in Turkey because, the country has dynamic economic development and rapid population growth. And the World Energy Council has concluded that growth based only fossil fuels and hydroelectric generation would not be sustainable and an expanded role of nuclear energy must be considered. The future of nuclear power utilization in all countries in the world will depend mainly on how the general public perceives it. This makes the public information a very sensitive and an important issue and it should be taken very seriously. Experts should consider the socio-economic structure of the country before taking the appropriate steps. The way the message is given, is, as important as the message itself. This should be done in the following manner. 1) Be friendly, talk friendly; 2) Don't forget, the target need to be informed; 3) Don't describe, but explain using healthy discussion; 4) Don't simplify, but clarify; 5) Don't try to use statistics, but tell the truth; 6) Don't use confused numbers but give examples; 7) Don't hesitate, be stable; 8) Don't use details, decide on a central message. In this manner, current activities in the area of nuclear energy and civil society should be pursued and their results carefully evaluated. Participation of public representatives, from primary school students to universities and decision makers should remain in current activities

  5. Reorientation of the Brazilian nuclear program and the function of technique community

    International Nuclear Information System (INIS)

    Once the available hydroelectric potentials have been developed, probably in 30 years, Brazil will need an alternative source for electric generation. Fossil fuels are limited in quantity and present serious health and environmental problems. Other sources such as solar and fusion energies are yet to be proved technologically and socio-economically and cannot be relied on in a rational planning for the future. Nuclear energy generated in Liquid metal fast breeder reactors is technologically proven, present minimum adverse effects, is economically competitive today, and has the capacity to supply all the electric power for centuries based on domestic resources. The nuclear community has the responsability to formulate and execute a program for technology development as soon as possible and to communicate to the people the necessity and merits of nuclear energy.

  6. Hidden costs of a typical embodied energy analysis: Brazilian sugarcane ethanol as a case study

    International Nuclear Information System (INIS)

    Worldwide human production systems are tightly coupled to fossil-based energy, the source of which will not be available at low cost in the foreseeable future. Alternative energy sources are being sought for, among which those derived from biomass are considered to have great potential. Brazilian ethanol sugarcane produced at a large scale is being classified in scientific papers and politics as a renewable energy source. However, only the energy return on investment (EROI) and/or the amount of CO2 released to atmosphere have been considered as indicators of renewability. This work aims to discuss some theoretical points, within an embodied energy analysis, that make its use inappropriate for answering all issues related to the concept of renewability. Emergy accounting (with an “m”) is used as a comparative tool and the Brazilian sugarcane ethanol is evaluated as case study. An EROI of 6.7 for ethanol was obtained, showing that for each unit of “commercial energy” invested within the process, 6.7 units of another kind of energy is obtained – this index shows an excellent value for energy efficiency, but it does not reflect the renewability of ethanol. On the other hand, emergy accounting shows a renewability index of 19%, indicating a low rating for sugarcane ethanol. All scientific methodologies available to assess potential energy sources have their pros and cons, but the analyst must be aware that each methodology supplies different indicators with different meanings. Energy analysts should use methodologies appropriately, avoiding wider conclusions not actually represented by indices calculated. - Highlights: • The renewability discourse of biofuels is discussed focusing on the Brazilian sugarcane ethanol. • Both energy efficiency and CO2 emitted hardly indicate the renewability of biofuels. • Emergy evaluation is introduced as a potential tool when assessing renewability. • Analysts must use methodologies accordingly and avoid general

  7. Nuclear Energy: Combating Climate Change

    International Nuclear Information System (INIS)

    Global electricity demand is expected to increase strongly over the coming decades, even assuming much improved end-use efficiency. Meeting this demand while drastically reducing CO2 emissions from the electricity sector will be a major challenge. Given that the once-significant expectations placed on carbon capture and storage are rapidly diminishing, and given that hydropower resources are in limited supply, there are essentially only two options to de-carbonise an ever increasing electricity sector: nuclear power and renewable energy sources such as wind and solar PV. Of these two options, only nuclear provides firmly dispatchable base-load electricity, since the variability of wind and solar PV requires flexible back-up that is frequently provided by carbon-intensive peak-load plants. The declining marginal value of electricity production and the security of electricity supply are additional issues that must be taken into account. Nuclear power plants do, however, face challenges due to their large up-front capital costs, complex project management requirements and difficulties in siting. As technologies with high fixed costs, both nuclear power and renewables must respond to the challenge of acquiring long-term financing, since investments in capital-intensive low-carbon technologies are unlikely to be forthcoming in liberalised wholesale markets. In order to substantially de-carbonise the electricity systems of OECD countries, policy-makers must understand the similarities, differences and complementarities between nuclear and renewables in the design of future low-carbon electricity systems. The value of dispatchable low-carbon technologies, such as hydro and nuclear, for the safe and reliable functioning of electricity systems must also be recognised. Should the de-carbonisation of electricity sectors in the wake of COP 21 become a reality, nuclear power might well be the single most important source of electricity by 2050, thanks mainly to the contribution

  9. Nuclear energy, radiation and environment

    International Nuclear Information System (INIS)

    Over the past few decades, energy has been the subject of much debate. Energy is the backbone of technology and economic development. Today, most machines run on electricity and they are needed to make anything and everything. Hence, our energy requirements have spiraled in the years following the industrial revolution. This rapid increase in use of energy has created problems of demand and supply in addition to the environmental consciousness which picked momentum in last decades of 20th century. The impending crisis the world over due to overuse of nonrenewable energy sources to reduce this gap shall soon lead to a situation for all concerned to take a prudent decision to tap other sources of energy, including relatively new renewable sources. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly. The drive for more energy has had the happy consequences of spawning new technologies and improving earlier ones. Emphasis on renewable sources has resulted in viable harnessing of solar, wind and tidal energies. Even though these sources offer relatively clean energy, their potential to supply reliable energy in large scale in an economically viable way is limited. Nuclear energy offers a major source of commercial energy, which is economic, reliable and environmentally benign

    The present dissertation analyses the retaking of the debate over Brazilian nuclear Program's recovery by Luis Inacio Lula da Silva government, based on the defense of the utilization of an already acquired technology of its own to enrich uranium. In spite of the intrinsic duality on this subject and having in mind the pacific ends concerning the utilization of such technology by Brazil, the hypothesis sustained in this work is that the Program's defense is considered a strategy of sovereign international insertion with relative autonomy and an instrument of national valorization against other powers. In order to verify the hypothesis outlined above, we will analyse the actual government, comparing it to, two other moments in Brazilian History in which the nuclear issue also acquired preponderance on the national agenda, namely, Geisel and Sarney governments. Although these three moments differ in relation to their internal political regime, our goal is to identify their similarities. (author)

    The author is of the opinion that the ethical aspect suffers no rival points of view. From that he concludes the necessity of a fair public discussion about the rank and urgency of the goods, values, and interests in hand. He calls for a moratorium: before the final option on the future way of energy supply, the scientific and economic competitional advantage of the strict course of large-scale technologies must be balanced. In order to render medium-scale technologies comparable at all from the economic and technical point of view, alternative technology research ought to be promoted for a couple of years under the same financial conditions and with the same expenditure of personnel.

    International Nuclear Information System (INIS)

    Early this year the Government of the Republic of Lithuania has basically approved and submitted to the Parliament (Seimas) for their approval the new draft of the National Energy Strategy. It still envisages two scenarios for the Ignalina Nuclear Power Plant. In accordance with one of them, the nuclear plant is to be shut down fairly soon. The greatest advantage of any commercial nuclear plant is that the share of fuel in the production cost is low. That is why efforts are being made to operate nuclear power plants to their full capacity all over the world. At the meantime a system of legal regulation and organisational management has been created and is functioning in Lithuania; Lithuania has joined the key international agreements that regulate the use of nuclear energy; a lot has been done to upgrade safety and reliability of the Ignalina NPP. Lithuania is going to stick to the policy of openness and co-operation with international organisations concerned, at the same time defends the interests of country's population

  14. Theological reflections on nuclear energy

    International Nuclear Information System (INIS)

    It is for a long time that, in this journal also, nuclear energy has been discussed in great detail with respect to its scientific, technical and engineering aspects. In connection with the public controversy about electricity generation being performed on an nuclear basis, the political, sociological and ethical aspects of nuclear energy have been discussed, too. As a third category, also theology plays an important role in this controversy. A theological discussion must include an explicit presentation of the relationship between mankind, nature and God, and must cover the insights and necessities of this relationship. On the basis of assumed rules, the referency system for this is not subject to scientific debate since the points of view as well as the methodology and the presuppositions forming part of theology generally appear strange to ordinary science. The controversy about nuclear energy has become a matter about which also the World Council of Churches as well as the National Council of Churches, and many other religious groups are concerned. For this reason, the editorial department of this journal would like to inform its scientific readers about how this controversy appears from theological standpoints. The author's considerations are based on the understanding of nature, mankind and God as it has been handed down in the Hebrew bible an in the Septuagint; it is confined to categories which are derived from our religious heritage.

    International Nuclear Information System (INIS)

    With this report the German Federal Diet submits the final results of the opinion-forming and decision-making process concerning the recommendations made by the investigation committee 'Future Nuclear Energy Policy' in June 1980. By means of this report it is intended to point out to an interested public the difficult and time-consuming process of parliamentary decision-making. This report is also to be seen as the final opinion delivered on the recommendations made by the investigation committee. The recommendations were to continue to pursue the peaceful use of nuclear energy, the necessity and technical justifiability of which had basically been approved by all parliamentary groups. In view of the import of the subject and in recognition of the work done by the investigation committee, the German Parliament has thoroughly discussed the report and has reviewed the analyses and recommendations in conjunction with other political fields to be considered. One part of the recommendations was taken up almost unanimously. As far as the safety of nuclear installations is concerned, the investigation committee could not submit any new findings which would give reasons for modifying the hitherto positive assessment of the safety of nuclear installations. The recommendations of the investigation committee mainly referred to the decision-making process in the field of energy policy which will effect the next decade. What fundamental decisions are to be made until when was pointed out as well as the findings and experience to be made until then. (orig./HP)

  16. Hydrogen economy and nuclear energy

    International Nuclear Information System (INIS)

    Global energy outlooks based on present trends, such as WETO study, give little optimism about fulfilling Kyoto commitments in controlling CO2 emissions and avoiding unwanted climate consequences. Whilst the problem of radioactive waste has a prominence in public, in spite of already adequate technical solutions of safe storage for future hundreds and thousands of years, there s generally much less concern with influence of fossil fuels on global climate. In addition to electricity production, process heat and transportation are approximately equal contributors to CO2 emission. Fossil fuels in transportation present also a local pollution problem in congested regions. Backed by extensive R and D, hydrogen economy is seen as the solution, however, often without much thought where from the hydrogen in required very large quantities may come. With welcome contributions from alternative sources, nuclear energy is the only source of energy capable of producing hydrogen in very large amounts, without parallel production of CO2. Future high temperature reactors could do this most efficiently. In view of the fact that nuclear weapon proliferation is not under control, extrapolation from the present level of nuclear power to the future level required by serious attempts to reduce global CO2 emission is a matter of justified concern. Finding the sites for many hundreds of new reactors would, alone, be a formidable problem in developed regions with high population density. What is generally less well understood and not validated is that the production of nuclear hydrogen allows the required large increases of nuclear power without the accompanied increase of proliferation risks. Unlike electricity, hydrogen can be economically shipped or transported by pipelines to places very far from the place of production. Thus, nuclear production of hydrogen can be located and concentrated at few remote, controllable sites, far from the population centers and consumption regions. At such

    International Nuclear Information System (INIS)

    Radiation remains one of the least understood or accepted forms of energy in society as far as the general population is concerned. People are jubilant when radiation is successful in detecting or destroying cancer cells, but protest loudly when a shipment of radioactive waste moves through their community. The public fears nuclear technology because the information they hear only relates to the risk. To dispel public anxiety and allow the nuclear industry to move forward, clear and rational information, which paints a more balanced picture of the benefits of radiation and the risks involved, is needed.

    Full Text Available The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a variety of end-products such as food, energy, and fiber; thus, taking into account the similarity in end-product of different crops (e.g.: sunflower, peanuts, or soybean for oil it is possible to evaluate which crops require less energy per functional unit, such as starch, oil, and protein. This information can be used in decision-making about policies for food safety or bioenergy. In this study, 23 crops were evaluated allowing for a comparison in terms of energy embodied per functional unit. Crops were grouped as follows: starch, oil, horticultural, perennial and fiber, to provide for a deeper analysis of alternatives for the groups, and subsidize further studies comparing conventional and alternative production systems such as organic or genetically modified organisms, in terms of energy. The best energy balance observed was whole sugarcane (juice, bagasse and straw with a surplus of 268 GJ ha−1 yr−1; palm shows the highest energy return on investment with a ratio of approximately 30:1. For carbohydrates and protein production, cassava and soybean, respectively, emerged as the crops offering the greatest energy savings in the production of these functional foods.

    The symmetry energy coefficients for nuclei with mass number A=20~250 are extracted from more than 2000 measured nuclear masses. With the semi-empirical connection between the symmetry energy coefficients of finite nuclei and the nuclear symmetry energy at reference densities, we investigate the density dependence of symmetry energy of nuclear matter at subnormal densities. The obtained results are compared with those extracted from other methods.

  7. Nuclear energy propulsion in space

    International Nuclear Information System (INIS)

    Nuclear energy can be used under two different ways in spatial applications, first the most common is the production of electricity that is used to supply an electrical propulsion system. The second way is the thermal propulsion where the nuclear reactor is considered as a heat exchanger whose purpose is to heat a gas that will expand in a nozzle. The thermal propulsion implies that the nuclear fuel and some reactor components will have to sustain very high temperatures ( > 2000 K) and important temperature gradients over short time intervals. Because of size and mass constraints propulsion reactors require highly enriched uranium fuels, in such cases power densities reach 1 to 10 MW / liter of core, which is by 1 to 2 orders of magnitude bigger than in a PWR-type power reactor, this represents a true technological challenge. In this article 2 projects: ERATO concerning spatial power generation and MAPS concerning thermal propulsion are presented. (A.C.)

  8. Suppose we renounce nuclear energy.

    International Nuclear Information System (INIS)

    The paper presents the highlights of the report by the 'Commission on Consequences' set up by the Swedish Government. The study is based on the reference alternative with the aim to complete as many as twelve nuclear power plants by 1990, whereas the abolition alternative provides the abolition of nuclear energy within the next ten years. To renounce nuclear power plants means to abolish electric power. The consequences of the abolition for society, economy, and environment are discussed by three forecasts of the electric power demand. Coal has increasingly to bear the main burden of supply, more heating plants have to be built, houses being heated nowadays by means of electric power have to be converted to oil and the dependency on oil imports would rather be increased than reduced.

  11. The sustainable development of nuclear energy

    International Nuclear Information System (INIS)

    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.

  12. The Brazilian fuel substitution dilemma: Recent experience from an energy supply study

    International Nuclear Information System (INIS)

    The paper is intended as a basis for discussing strategic supply options and their economic impacts for an advanced developing country. It represents a first brief assessment of an energy systems analysis project which was carried out by the Secretaria de Tecnologia do Ministerio das Minas e Energia and Kernforschungsanlage Juelich between May 1982 and May 1984. In view of the fact that Brazil had to spend 50% of its annual export revenues to import oil in 1980 and taking into account that this import bill of roughly US $10x109 affects the balance of payments and foreign debt burden significantly, the Brazilian Ministry of Energy and Mines decided to evaluate the consequences of alternative supply strategies utilizing domestic energy resources with priority. There is a big challenge and opportunity to develop and utilize domestic energy resources, mainly hydropower, coal for thermal uses in industry and biomass for the rural and residential sectors. Supplying the Brazilian energy system in general will not be the problem. The oil substitution dilemma becomes obvious when one looks at the specific requirements of the transport sector. For historical reasons the transport system is nearly totally based on road transport. Around two thirds of the total fuel consumption is swallowed up by this sector. Replacing crude oil means replacing gasoline and diesel. This means producing ethanol from sugar-cane and methanol from hard coal. These alternatives are leading to a significantly higher overall system cost of the energy system. The efforts of the Brazilian Government to replace imported fuel oil and ensure a self-sufficient domestic energy supply of high security were financed until now by a significant public budget deficit. This strategy will run into difficulties in the future, as the latest IMF negotiations show. One way to escape this dilemma can be a careful examination of ways to reconstruct the transport system.

  13. Energy consumption indicators and CHP technical potential in the Brazilian hospital sector

    International Nuclear Information System (INIS)

    Electricity demands in hospitals are characterized by their need for high quality, guaranteed supplies. The existence of captive electricity uses and the size and regularity of the electrical and heat loads required by hospitals are aspects that could well buttress the possibility of installing cogeneration plants fired by natural gas (CHP). The purpose of this paper is to estimate the CHP technical potential in Brazilian hospitals. Based on a classification of Brazilian hospitals by specific energy consumption indicators, this potential is assessed, taking into consideration gas fueled engines associated with absorption cooling systems. A potential figure of approximately 500 MWe was obtained, whose effective implementation runs up against the obstacles inherent to Brazil's hospital sector, listed at the end of this paper. Consequently, some actions are proposed for surmounting these barriers

  14. Nuclear re-think [The case for nuclear energy

    International Nuclear Information System (INIS)

    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 CO2 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

  15. Energy commercialization in the new environment of the Brazilian electric power sector. A methodology for production allocation strategies analysis

    International Nuclear Information System (INIS)

    The restructuring of the Brazilian Electric Sector has modified the rules for purchase and sale of energy, resulting in the creation of the Wholesale Energy Market. In this new context, the decision of the exposure level to the spot market price and the purchase of energy through bilateral contracts becomes so much a strategic variable for consumers or dealers, as for hydro and thermal generators. This work presents a methodology for planning of energy commercialization envisaging purchase and sale energy opportunities provided by the new Regulatory Framework of the Brazilian Electric Sector.

  16. Strategies of implementation and effects of national technological development big programmes: experiences of Brazilian Navy nuclear programme

    International Nuclear Information System (INIS)

    The science and technology development, for which creativity and innovation must be always present, are supported by three fundamental principles: the first is related to existence of human brains and good conditions for its realizations; the second could be located in people and institution mobilization for accomplishment of objectives and goals which generate strategic or social benefits; the third are relates to a national effort, making sufficient resources reach the scientific and technological areas. Brazilian Navy, trough its Technological Center in Sao Paulo, developed a particular approach to follow these principles in order to get a technological 'jump' which will give Brazilian Naval Power, through submarine nuclear propulsion, the capabilities required by the nation's importance in the international scene. This Program, started in the early 80's, has presented very impressive results, not only in the vertical sense pointing to its goal, but also in the horizontal sense of diversification, referring to a deliberate change of activities away from purely nuclear, and spin-offs, referring to application of results of nuclear R and D outside nuclear sector.

  17. Man, environment and nuclear energy

    International Nuclear Information System (INIS)

    The acceptability of nuclear fission as energy source is governed by three factors, economic, ecological and sociological. It is necessary to account first for the economic context and for the state of natural resources: gradual exhaustion of fossil fuels as a result of ever-increasing demands. The biological risk concept which determines the acceptable industrial application level is the second factor to be considered. The danger of radioactive contamination is almost inexistent except in the accident hypothesis, and power stations are built with excessive safeguards against hypothetical accidents. The idea of systematic processing of all working effluent to reduce radioactive waste discharge by several orders of magnitude (zero release principle) is being examined. At present, the waste discharge levels are always well below the limits set by the CIPR and present no danger to the population. The only serious problems seem to be the disposal of radioactive wastes and the plutonium non-proliferation question bound up with breeder reactors. Whereas vitrification, the new 'Synroc' process, offer some solution to the radioactive waste conditioning problem, responsibility for the proliferation of nuclear weapons rests with the human conscience alone. The development of nuclear power stations over several decades seems to present no inacceptable danger and offers the best compromise between growth and minimum risk requirements. The third factor to be accounted for is the opposition displayed by a fraction of the population to the development of nuclear energy for peaceful applications

  18. Nuclear energy risks and benefits

    International Nuclear Information System (INIS)

    The report was prepared as part of the Ohio River Basin Energy Study (ORBES), a multidisciplinary policy research program. The study region consists of all of Kentucky, most of West Virginia, and substantial portions of Illinois, Indiana, Ohio, and Pennsylvania. By 1988, coal-fired electrical generating capacity in the region is expected to total over 100,000 MWe, versus about 11,000 MWe projected for nuclear-fueled capacity by that year. Thus, the ORBES emphasis was on coal-fired generation. This report attempts to fill in some of the gaps in the relative lack of emphasis on the risks and benefits of nuclear electricity production in the study region. It covers the following topics: (1) basic facts about radiation, (2) an overview of the current regulatory framework of the nuclear industry, (3) health risks associated with electricity production by LWRs, (4) the risks of nuclear proliferation, terrorism, and sabotage, (5) comparative economics and healthy risks of coal versus nuclear, and (6) the March 1979 accident at Three Mile Island

  19. Nuclear energy - some regulatory aspects

    International Nuclear Information System (INIS)

    The nuclear industry is often perceived by the public as being uniquely hazardous. As a consequence, the demands placed upon a nuclear regulatory agency invariably include sorting out the valid from the invalid. As the public becomes better informed, more time should become available for regulating the industry. The Canadian nuclear safety philosophy relies upon fundamental principle and basic criteria which licensees must show they are meeting at all stages in the development of a nuclear facility. In reactors, the concept of defence in depth involves the use of well-qualified personnel, compliance with national and international engineering codes and standards, the separation of process and safety systems, frequent testing of safety systems, redundancy in monitoring, control and initiation systems, multiple barriers against fission product release, and strict enforcement of compliance measurements. The Atomic Energy Control Board is writing a set of licensing guides to cover the whole nuclear fuel cycle; however, these will not lead to the impsition of a 'design by regulation' approach in Canada.

  20. The nuclear energy, future of ecology

    International Nuclear Information System (INIS)

    For the author, nuclear energy is the energy of future, because it's the only one which allows to satisfy energy needs increases in the 21st century with a pollution reduction. This book presents the nuclear paradox which is: nuclear electricity is the most contested energy source by ecologists, while in reality, it is the cleanest energy, the most surveyed and the most respectful of environment among the massively available energies. (A.B.)

    The utilization of nuclear energy and the predicted impact of future uses of nuclear energy are discussed. Areas of application in electric power production and transportation methods are described. It is concluded that the need for many forms of nuclear energy will become critical as the requirements for power to supply an increasing population are met.

  3. Nuclear power in the World Energy Outlook

    International Nuclear Information System (INIS)

    In this paper, I shall discuss nuclear power in the context of the International Energy Agency's World Energy Outlook. I shall also draw on the implications for nuclear power of three major energy policy issues: sustainability, climate change and electricity market competition. Those issues were addressed in detail in a recent IEA publication, entitled Nuclear Power. (author)

  4. Brazilian waste potential: energy, environmental, social and economic benefits

    International Nuclear Information System (INIS)

    The potential energy that could be produced from solid wastes in Brazil tops 50 TWh. Equivalent to some 17% of the nation's total power consumption at costs that are competitive with more traditional options, this would also reduce greenhouse gases emissions. Moreover, managing wastes for energy generation purposes could well open up thousands of jobs for unskilled workers. Related to power generation and conservation, energy use requires discussions on the feasibility of each energy supply option, and comparison between alternatives available on the market. Power conservation is compared to projects implemented by the Federal Government, while power generation is rated against thermo-power plants fired by natural gas running on a combined cycle system. Although the operating costs of selective garbage collection for energy generation are higher than current levels, the net operating revenues of this scheme reach some US$ 4 billion/year. This underpins the feasibility of garbage management being underwritten by energy uses and avoided environmental costs. The suggested optimization of the technical, economic, social and environmental sustainability of the expansion of Brazil's power sector consists of compatibilizing the use of fossil and renewable fuels, which is particularly relevant for hybrid thermo-power plants with null account on greenhouse gases emissions

  5. Nuclear Reactions at Intermediate Energies

    In the domain of Nuclear reactions at intermediate energies, the QCD coupling constant $\\alpha_s$ is large enough ($\\sim$ 0.3 - 0.5) to render the perturbative calculational techniques inapplicable. In this regime the quarks are confined into colorless hadrons and it is expected that effective field theories of hadron interactions via exchange of hadrons, provide useful tools to describe such reactions. In this contribution we discuss applications of one such theory, the effective Lagrangian model, in describing the hadronic reactions at intermediate energies whose measurements are the focus of a vast international experimental program.

  6. Nuclear energy prevents ecological disaster

    International Nuclear Information System (INIS)

    Full text: The booklet containing 6 pages brings forth 10 arguments and facts called upon to convince the reader that the nuclear energy is the main if not the only means to avoid catastrophic ecological consequences caused by the increasing non-usage of the organic fuel. By the middle of the 2lst century the triple growth of the worldwide energy consumption will inevitably cause a significant increase Of CO2, NO2, SO2 emission and reduction of oxygen content in the Earth atmosphere if it is satisfied as before due to the combustion of coal, petrol and gas. Significant changes of the environment are turning out to be a serious threat to the existence of mankind. Such dispiriting fact and some other negative factors inherent in the so-called 'fire' energy oppose to the remarkable advantages already demonstrated by the nuclear energy supposed to become the energy of the 21st century. The text will contain the tables and color pictures to further the perception of the material set forth in the booklet. (author)

  7. Nuclear energy and social impact

    International Nuclear Information System (INIS)

    Economic development and population increase are boosting a new process of energy demand all around the world which implies also a protection of the environment and, consequently, the reduction of emissions of CO2, a challenge that has to be solved. Fossil fuels represent the cheapest costs in capital and have as common features that their exploitation is based on largely known technologies, having developed a big experience in construction, operation and maintenance. However they are big environment polluters. Nuclear energy fulfils three of the main objectives that should be pursued for a steady development: 1. It does not emit Greenhouse gases. 2. It is the cheapest produced energy. 3. It guarantees a security in its supply due to the fact, among others, that it is not conditioned by external factors. However, as any other energy source, nuclear power has its own drawbacks. Some are real and some are fictitious. For this reason it becomes necessary to improve the social image of this source of energy, so as to counteract the negative consequences of the antinuclear discourse, promoted late in the seventies that has permanently undermined public acceptance

    The availability of energy resources is a central point to economic development. The energy matrix of most countries is based on the consumption of fossil fuels, which adds annually over 5 billion tons of carbon into the atmosphere. The energy consumption in developing countries has quadrupled since the 60s further aggravating global environmental conditions. The need to implement alternative energy sources to the energy matrix was proved. In addition, Brazil has a large number of people without access to electricity, which affects the quality of life of these populations. In this context, it is necessary to think in economic development way, and then the sustainable and alternative sources appear as an option for its features and its availability in Brazil. The solar energy captured by photovoltaic cells can be highlighted in the Brazilian scenario because of its wide availability, especially in the Northeast. The aim of this paper is to estimate the economic feasibility of insertion of solar systems in small communities in the Brazilian Northeast, considering environmental costs involved in electricity generation. The methodology is based on economic concepts and economic valuation of environmental resources. The results shows that solar power is becoming increasingly competitive due to reduced costs of components and due to the environmental costs reduced when compared with fossil fuels. (author)

  9. Energy efficiency and restructuring of the Brazilian power sector

    Energy Technology Data Exchange (ETDEWEB)

    De Martino Jannuzzi, Gilberto [State University of Campinas, Sao Paulo, (Brazil)

    1999-07-01

    Since the early nineties Brazil has initiated a program of reforms in its electric sector which includes utility privatization, de-verticalization. The main objectives were to promote a market-oriented energy industry attractive to private investments. This has led to the loss of sponsorship for the public-interest programs formerly undertaken by the state utilities. In particular, of significant concern are the programs for promotion of energy efficiency, renewable energy technologies, rural electrification and environmental protection. In the midst of the privatization effort, the National Agency for Electrical Energy ANEEL was created (end of 1997). One of the tasks of the regulatory agency is to provide funds and incentives to energy conservation. In this paper we review the role of ANEEL in promoting energy efficiency investments in the context of a market-oriented sector, its limitations and prospects. [Spanish] Desde principios de los anos noventa Brasil ha iniciado un programa de reformas en su sector electrico que incluye la privatizacion del servicio electrico y la desverticalizacion. Los objetivos principales eran promover una industria de la energia orientada comercialmente de la energia electrica, atractiva a las inversiones privadas. Esto ha conducido a la perdida de patrocinio de los programas de interes publico emprendidos antes por las empresas electricas del estado. En particular, de preocupacion significativa estan los programas para la promocion del rendimiento energetico, de las tecnologias de la energia renovable, de la Electrificacion rural y de la proteccion del medio ambiente. En medio del esfuerzo de la privatizacion, la agencia nacional para la energia electrica ANEEL fue creada (finales de 1997). Una de las tareas de la agencia reguladora es proporcionar fondos e incentivos a la conservacion de energia. En este trabajo repasamos el papel de ANEEL en promover inversiones del rendimiento energetico en el contexto de un sector orientado

    This document provides many data and charts on the energy domain: energy consumption, energy demand, the reserves, the climatic changes, the renewable energies, the energy cost, the radioactive wastes management, the new nuclear technology. (A.L.B.)

  12. Nuclear energy - perception, policy and practice

    International Nuclear Information System (INIS)

    The arguments in favour of nuclear power are presented. It is argued that the impact of nuclear energy on the world is already substantial and that the risks have been overstated. The public perception of nuclear technology in general is often shaped by poor education, a hostile, sensation-seeking media and confusion between the peaceful nuclear fuel cycle and nuclear weapons. Nuclear policy in Australia is reviewed

  13. Contribution to the study on and evaluation of radioactive waste generation in connection with the Brazilian Nuclear Program

    International Nuclear Information System (INIS)

    A general description is given of the causes of pollution in the nuclear industry. Emphasis was given to the radioactive pollution, especially radioactivity of fission products (FP). Physical mathematical models were established to calculate the FP activities 'in' and 'out' of the reactor and the yearly accumulated activities. To calculate FP activities 'in' reactor, all physical process of formation and destruction of nuclides were considered: nuclear fission; neutron absorption and radioactivity decay. The necessary input data were analysed and criticised. The specific activities of the discharged fuel were calculated and also their evolution outside reactor. The annual accumulation of FP activities were also calculated for the reference case: the Brazilian Nuclear Program for a 50 year horizon. The results were commented and specific discussions and comparison with other similar studies were made. (Author)

  14. Economic Analysis of Nuclear Energy

    International Nuclear Information System (INIS)

    This study consists of various issues as follows; electricity price regulation in the liberalized electricity market, establishment of carbon emission limit in national electricity sector, the role of nuclear power as an future energy supply option, the future prospect of CO2 capture and sequestration and current research status of that area in Korea, and Preliminary economic feasibility study of MIP(Medical Isotopes Producer). In the price regulation in the liberalized electricity market, the characteristic of liberalized electricity market in terms of regulation was discussed. The current status and future projection of GHG emission in Korean electricity sector was also investigated. After that, how to set the GHG emission limit in the national electricity sector was discussed. The characteristic of nuclear technology and the research in progress were summarized with the suggestion of the possible new application of nuclear power. The current status and future prospect of the CO2 capture and sequestration research was introduced and current research status of that area in Korea was investigated. Preliminary economic feasibility study of MIP(Medical Isotopes Producer), using liquid nuclear fuel to produce medical isotopes of Mo-99 and Sr-89, was performed

  15. Peaceful uses of nuclear energy

    International Nuclear Information System (INIS)

    It is now a quarter of a century since nuclear energy was introduced to the public. Its introduction was made in the most dramatic, but unfortunately in the most destructive way - through the use of a nuclear weapon. Since that introduction enormous strides have been made in developing the peaceful applications of this great and versatile force. Because these strides have always been overshadowed by the focusing of public attention on the military side of the atom, the public has never fully understood or appreciated the gains and status of the peaceful atom. This booklet is an attempt to correct, in some measure, this imbalance in public information and attitude. It is a compilation of remarks, and excerpts of remarks, that I have made in recent years in an effort to bring to the public the story of the remarkable benefits the peaceful atom has to offer man. This is a story that grows with the development and progress of the peaceful atom. It must be told so that we can learn to use the power of nuclear energy wisely and through this use help to build a world in which the military applications of the atom will never again be a threat to mankind

  16. Innovation in nuclear energy technology

    International Nuclear Information System (INIS)

    Innovation has been a driving force for the success of nuclear energy and remains essential for its sustainable future. Many research and development programmes focus on enhancing the performance of power plants in operation, current fuel design and characteristics, and fuel cycle processes used in existing facilities. Generally performed under the leadership of the industry. Some innovation programmes focus on evolutionary reactors and fuel cycles, derived from systems of the current generation. Such programmes aim at achieving significant improvements, in the field of economics or resource management for example, in the medium term. Often, they are undertaken by the industry with some governmental support as they require basic research together with technological development and adaptation. Finally, large programmes, often undertaken in an international, intergovernmental framework are devoted to design and development of a new generation of systems meeting the goals of sustainable development in the long term. Driving forces for nuclear innovation vary depending on the target technology, the national framework and the international context surrounding the research programme. However, all driving factors can be grouped in three categories: market drivers, political drivers and technology drivers. Globally, innovation in the nuclear energy sector is a success story but is a lengthy process that requires careful planning and adequate funding to produce successful outcomes

  17. Nuclear energy for oil sands

    International Nuclear Information System (INIS)

    In 1980, Atomic Energy of Canada Limited, working with a number of Alberta-based companies, assessed the technical and economic feasibility of using a CANDU nuclear reactor to raise the production steam for the recovery of bitumen. The study followed several years of analysis which identified oil sands projects as the most appropriate single users of thermal energy of the amount and quality available from reactors. Over the life of an oil sands project a steam supply system based on a nuclear reactor is expected to offer a substantial cost advantage (25 - 50%) over the alternative system based on coal as the make-up fuel. Steam from natural gas is marginally more expensive than that from coal because the cost of natural gas is expected to escalate at a rate higher than inflation. For shallow deposits (150 - 250 metres) using intermediate pressure steam, the commercially proven Pressurized Heavy Water (PHW) reactor is most suitable. For deeper deposits (250 - 650 metres), the PHW reactor can provide the higher pressure steam using a compressor, but only with a reduction in thermal efficiency that substantially reduces its cost advantage. The CANDU Organic Cooled Reactor (OCR), however, can provide the high presure steam required with the large cost advantage. The economic benefit of nuclear steam supply systems, a saving of $2-4 per barrel of product, is large enough to justify a more detailed study

  18. Nuclear Energy. Communicating with the Public

    International Nuclear Information System (INIS)

    Information and communication with the public often appear to be the Achilles heel of nuclear energy, despite the considerable effort devoted to them. This report is based on the conclusions of several workshops organised by the OECD Nuclear Energy Agency for public information specialists. It discusses the principles and practices leading to better communication with the public in four nuclear energy fields: radiation protection, radiological emergencies, routine operation of nuclear plants and radioactive waste management

  19. Analysis of normative requirements for the development and implementation of a quality management system in Brazilian nuclear installations and activities

    International Nuclear Information System (INIS)

    The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

  20. Communication on the risk of nuclear energy

    International Nuclear Information System (INIS)

    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)
