The Japan Atomic Energy Research Institute was established in 1956 in conformity with the national policy to extensively conduct the research associated with nuclear energy. Since then, the research on nuclear energy safety has been conducted. In 1978, the Division of Reactor Safety was organized to conduct the large research programs with large scale test facilities. Thereafter, the Divisions of Reactor Safety Evaluation, Environmental Safety Research and Reactor Fuel Examination were organized successevely in the Reactor Safety Research Center. The subjects of research have ranged from the safety of nuclear reactors to that in the recycling of nuclear fuel. In this pamphlet, the activities in JAERI associated with the safety research are reported, which have been carried out in the past two years. Also the international cooperation research program in which JAERI participated is included. This pamphlet consists of two parts and in this Part 2, the environmental safety research is described. The evaluation and analysis of environmental radioactivity, the study on radioactive waste management and the studies on various subjects related to environmental safety are reported. (Kako, I.)

This keynote paper deals with: energy issues and nuclear power development in Japan, problems of radiation protection, licensing and safety regulations, research on LOCA and ECCS, stress corrosion cracks related to pressure vessels, nuclear fuel failures, steam generators, incidents, waste management and fuel cycle facilities. In conclusion it is stated that: on order to cope with global matters vitally affecting the electricity generation, taking into consideration Japanese specific energy issues, the nuclear power development has been an indispensable policy of Japan. In order to proceed with further development of nuclear power plants, it is necessary to obtain proper understanding by the public, showing assurance of the safety and reliable operation of nuclear power plants through daily plant operation. The nuclear safety issues should be considered from a global point of view. It is necessary to establish common safety standards which could harmonize the safety level of nuclear power plants in the world. The safety goal concerning severe accidents should be established as an internationally agreeable one. Japan has accumulated highly technological experience in maintenance of nuclear power plants. It is believed that the cumulative experiences in Japan can contribute to the further improvement of safety of nuclear power plants throughout the world, and for this aim a mutual information exchange should be encouraged

Women in Nuclear Japan (WiN-J) has been striving to promote activities that increase public acceptance of nuclear energy especially by women. According to a public opinion poll in 2009 by the Cabient Office, Government of Japan, the ratio of men who have confidence in nuclear power plant safety was 52.1%, while the ratio of females was only 32.5%. And the ratio of negative feeling about nuclear power among males was 45.8%, while the ratio of females was 61.2%. This indicates the necessity of communication to females to encourage them to accept nuclear power. WiN-J developed two methods of communication with the public and young people about the benefits of nuclear energy and the applications of radiation in many aspects of the life. The first is town hall meetings, and the other is education for university students in the style of a Science Cafe. Surprisingly, present university student never studied about nuclear energy when they were elementary or junior high school students. However, those students will have to educate their own children to use energy wisely in consideration of the limited energy resources in the coming years. WiN-J, therefore, gives them some relevant lectures on nuclear energy and radiation. Also WiN-J can be the models for female university students who have issues such as marriage, pregnancy, promotions, and transfers which can be discussed. We have to increase the numbers of female nuclear engineers to promote public trust in the safety of nuclear power plants. For this purpose, WiN-J encourages female university students to enter the nuclear industry. We recognize that to gain people's understanding of and trust in nuclear energy may take a long time. WiN-J will continue to fulfill our challenging mission for the peaceful use of nuclear energy. (author)

Japanese new governmental adminstrative system was restructured and became in operation from January 1, 2001 including newly establishment of the Ministry of Cabinet. Accordingly, Japanese nuclear administrative system were also changed significantly, in order to reflect the changing policy environment and response to them more efficiently in the use and development of nuclear energy. Atomic Energy Commission, Nuclear Safety Commission administrated by Science and Technology Agency in the past, were moved to the Ministry of Cabinet, and Integrated Science and Technology Council was also newly established under the Ministry of Cabinet. And Ministry of Economy, Trade and Industry(METI) is in charge of nuclear energy policy and the Ministry of Education, Culture, Sports, Science and Technology(MEXT) is in charge of nuclear academic science consequently. At the same time, the revision work of 'Long-term Program for Research, Development and Utilization of Nuclear of Japan' established in 1994, has been carried out from 1999 in order to set up the long term based national nuclear policy towards the 21st century, and finally the results were open to the public in November 2000. Major changes of nuclear policy of Japan the will be good references in the establishing future national nuclear policy for the use and development of nuclear energy

In order to alleviate the distrust surrounding the use of nuclear energy and operation of nuclear facilities, as well as to foster trust and find better ways to live in harmony with society, it is essential for the state and electric power utilities not to provide one-sided information, but to formulate adequate bilateral communication and dialogue with stake holders. In this study, we conducted a case study focused on four stake holder meetings with a view to ensuring safety in the use of nuclear energy and operation of nuclear facilities in Japan; the 'Community Meeting for Securing the Transparency of Kashiwazaki-Kariwa Nuclear Power Station (Chiiki-no-kai)'; the 'Monitoring and Evaluation Conference on Environmental Radiation', established by communities where nuclear facilities are installed; the 'Round-Table Conference on Nuclear Power Policy' and the 'Conference for Public Participation and Decision Making for Nuclear Energy Policy' organized by Japan Atomic Energy Commission. As a consequence, it has been observed that in each case varying opinions were summarized through stake holder meetings, but the fact that no system exists to reflect these opinions in design of the nuclear energy policy has emerged as a controversial point. This study suggests future efforts in regard to the requirements in Japan for stake holder meetings that are necessary for fostering trust and mutual understanding among stake holders including the state and local government, electric power utilities and local residents.

Today, world energy demands continue to increase, and over the middle and long-term, access to petroleum supplies may become difficult. At the same time, such serious environmental problems as global warming and acid rain, which are caused by the burning of fossil fuels, have drawn great public attention, and the international community has urged that solutions to them should be found. Because nuclear power offers an economically efficient, stable supply of energy whose production has little adverse effect on the environment, the world has recognized the necessity of continuing to develop and use it. The changing international political situation, however, has complicated nuclear energy matters. In Japan, particularly the collapse of the former Soviet Union and North Korea's announcement of its intention to withdraw from the Nuclear Weapons Non-Proliferation Treaty have been cause for concern. Under these circumstances, it has become increasingly important for Japan to secure stable sources of energy, since Japan is dependent on imports for its energy supply. To that end, Japan has steadily promoted the development and utilization of nuclear energy. In fiscal 1992, nuclear power accounted for 28.2 % of the total power generated by Japanese electric utilities. Japan has also worked steadily to develop a nuclear fuel cycle, which is important to the long-term stability of the energy supply. This publication describes the present status of nuclear energy development and utilization in Japan. (J.P.N.)

Confusion surrounding the concept of nuclear 'security'. 'Preventing Japan from going nuclear contributes to Japan's national security'?

International Nuclear Information System (INIS)

Kubota, Masafumi

2012-01-01

A law enacted on June 20 to establish a new Nuclear Regulatory Authority (NRA) fully separated from the nuclear promotional authorities. It added the provision, which says nuclear safety should be guaranteed not only to defend lives, people's health and the environment but also to 'contribute to Japan's national security', to Article 2 of the Atomic Energy Basic Law. NRA integrated the existing regulatory authorities for safety, security and safeguards, into one. Supporters of an amendment quietly slipped into the law were denying it could provide cover for military use of nuclear technology, but arouse international concern about recycling program of extracting plutonium from spent fuels. Nuclear policy minister said: 'The safeguards are in place to prevent nuclear proliferation. The world 'security' precisely means the prevention of nuclear proliferation.' If not used explicitly about safeguards, they left room for stretched interpretation. The author recommended the world' contribute to Japan's national security' should be deleted instead of explaining appropriately, both at home and abroad, the use of nuclear power in Japan limited to peaceful purposes.

Nuclear energy is a superior form of energy in that it delivers stable power supplies and counters global warming, and it is important to promote nuclear power generation as the core power sources for a nation. However, the Japanese environment surrounding nuclear energy is changing drastically, following the liberalization of market and recent series of troubles or falsifications shaking public confidence in nuclear energy. In the above mentioned situation, nuclear industries and organizations must fulfill their individual roles, and amass its strength to work toward enhancing industry initiatives for safety activities, securing safe / stable plant operations, restoring public confidence and initiate revitalization of nuclear energy operations. The Japan Nuclear Technology Institute (JANTI) has been established as a new entity for supporting and leading the industry's further progress in March 2005. Members of JANTI are not only utilities but also component manufacturers and constructors. JANTI enhance the technological foundation of nuclear energy based on scientific and rational data, coordinates its use among a wide range of relevant organizations, and helps members enhance their voluntary safety activities. At the same time, it is independent of utilities, and exercises a function of checking industry at the objective, third-party standpoint. As for the activities of JANTI itself, information disclosure and the establishment of a council comprising external members will enhance administration transparency. (author)

Highlights: • Chernobyl accident had limited influence on basic research in nuclear energy. • Budget allocation to R and D and number of published papers have recently decreased. • Citation network analysis revealed reactor safety and fusion as current research trend. • Nuclear energy research policy will change after Fukushima disaster. - Abstract: The decision-making process that precedes the introduction of a new energy system should strive for a balance among human security, environmental safeguards, energy security, proliferation risk, economic risks, etc. For nuclear energy, the Fukushima Daiichi nuclear disaster (Fukushima disaster) has brought forth a strong need for transvaluation of the present technology. Here, we analyzed bibliographic records of publications in nuclear science and technology to illustrate an overview and trends in nuclear energy technology and related fields by using citation network analysis. We also analyzed funding data and keywords assigned for each project by co-occurrence network analysis. This research integrates citation network analysis and bibliometric keyword analysis to compare the global trends in nuclear energy research and characteristics of research conducted at universities and institutes in Japan. We show that the Chernobyl accident had only a limited influence on basic research. The results of papers are dispersed in diverse areas of nuclear energy technology research, and the results of KAKEN projects in Japan are highly influenced by national energy policy with a focus on nuclear fuel cycle for energy security, although KAKEN allows much freedom in the selection of research projects to academic community

In Japan, the way of PA activities concerning nuclear power has relatively been one-sided and the content of the information which provided to the public has focused mainly on the safety and necessity of nuclear power generations unilaterally so far. But, with the incident of sodium leakage at the Monju plant occurred at December, 1995 and subsequent fire explosion at the Tokai reprocessing plant at March 1997, distrust of the public increased rapidly against the promotion of nuclear power development in Japan. According to the opinion poll carried out in February 1996, it was shown that 70.3% of the public felt that nuclear power is not safe, up from 57.8% of previous survey in November 1995. therefore, it has become important to gain public confidence in order to achieve nuclear power development programs, and clarification of the national policy for nuclear energy development are required strongly. As a result, a series of discussions were actively made at the round- tabled conferences held by Atomic Energy Committee, Japan s national body for promotion of nuclear energy utilization and development, and Advisory Committee for Energy held by MITI, to find out the way of how Japan's nuclear power development should be promoted. In conclusions of discussions, the important theme concerning the ideal method for proceeding PA activities were emphasized. To summarize these briefly, (1) reestablish the trust in the national nuclear policy among the public by transparency and openness, reflecting public opinions. (2) promote understanding and reach an agreement with the regional community where nuclear power plant are installed or are scheduled to be installed in the future. (3) explain and convey information so that the public will think together with us. As for the (3), we are making every effort to rouse public awareness to the importance of tackling severe energy situations in Japan and lead individual people to think seriously about the issues. For that purpose, we

The Japan Atomic Energy Commission has exerted efforts on the research of the safety of nuclear plants in Japan, and ''Nuclear plant safety research committees'' was established in August 1974, which is composed of the government and the people. The philosophy of safety research, research and development plan, the forwarding procedure of the plan, international cooperation, for example LOFT program, and the effective feed back of the experimental results concerning nuclear safety are reviewed in this paper at first. As for the safety of nuclear reactors the basic philosophy that radio active fission products are contained in fuel or reactors with multiple barriers, (defence in depth) and almost no fission product is released outside reactor plants even at the time of hypothetical accident, is kept, and the research and development history and the future plan are described in this paper with the related technical problems. The structural safety is also explained, for example, on the philosophy ''leak before break'', pipe rupture, pipe restraint and stress analysis. The release of radioactive gas and liquid is decreased as the philosophy ''ALAP''. And probability safety evaluation method, LOCA, reactivity, accident and aseismatic design in nuclear plants in Japan are described. (Nakai, Y.)

Development and application of nuclear safety goals in Japan. Lessons learnt from the case of 2003 draft safety goals

The Nuclear Safety Commission in Japan offered a detailed draft of nuclear safety goals to the public in 2003, though its position was ambiguous in nuclear safety regulation. This report shows the circumstances behind the development and application of 2003 draft safety goals based on our interviews with the experts who had been involved in making the draft. According to our interviews, they had intention to utilize safety goals for improving risk management of regulatory authority and nuclear energy industry, such as ameliorating deterministic regulations, accumulating experience of risk assessment and management, promoting related research, and communicating risks with general public. In practice, however, safety goals had functioned as a tool for emphasizing an assertion that 'nuclear power plants had already been safe enough'. We identified the following four major impediments to utilizing safety goals; 1) lack of sharing overall recognition of the importance of establishing safety goals among nuclear community, 2) excessive emphasis of internal event risks which leads to an inferior priority to tackle with the issue of external events risks, 3) adverse effect of 'tunnel-visioned incrementalism', that is, nuclear energy industrial entities are attracted their foci too much on what they have been told to do by regulators or local governments, and, 4) negative attitude to disclose the outcomes of risk assessment for fear of societal reactions. To encourage upcoming safety goals and risk management, this report provides the following points for overcoming these problems; 1) sharing insights on the reasons why nuclear community set up safety goals, 2) introducing the concept of adaptive risk management for maintaining questioning attitude, 3) conducting a periodic review of goal attainment level and also safety goals themselves from the eyes of a detached observer, and, 4) rebuilding relationship with society beginning with arguments with local stakeholders over

Two years have elapsed since the accident in Chernobyl nuclear power station shocked those concerned with nuclear power generation. The effect that this accident exerted on human environment has still continued directly and indirectly, and the reports on the effect have been made in various countries and by international organizations. In Japan, about the exposure dose of Japanese people due to this accident, the Nuclear Safety Commission and Japan Atomic Energy Research Institute issued the reports. In this report, the available data concerning the envrionmental radioactivity level in Japan due to the Chernobyl accident are collected, and the evaluation of exposure dose which seems most appropriate from the present day scientific viewpoint was attempted by the detailed analysis in the National Institute of Radiological Sciences. The enormous number of the data observed in various parts of Japan were different in sampling, locality, time and measuring method, so difficulty arose frequently. The maximum concentration of I-131 in floating dust was 2.5 Bq/m 3 observed in Fukui, and the same kinds of radioactive nuclides as those in Europe were detected. (Kako, I.)

The contributions of this publication first address the Japanese local context (organization, mentality, cultural background, thinking and action modes), and secondly the environmental and radiological impact of the Fukushima accident, notably in comparison with Chernobyl (contamination is much more localized, sometimes higher; a larger concerned population but quicker and more efficient protection measures; more severe consequences due to population displacement). The third article discusses the international impact of the accident: known or foreseen consequences on nuclear programs, discussion on safety strengthening and on governance, evolution of public opinion, possible consequences on climate negotiations. The last article proposes an overview of the current situation of Japan which must mobilize all the available energy resources to face the difficulties in electricity supply

The operating organization for nuclear power plants. Safety guide

International Nuclear Information System (INIS)

2001-01-01

This Safety Guide was prepared under the IAEA programme for safety standards for nuclear power plants. The present publication is a revision of the IAEA Safety Guide on Management of Nuclear Power Plants for Safe Operation issued in 1984. It supplements Section 2 of the Safety Requirements publication on Safety of Nuclear Power Plants: Operation. Nuclear power technology is different from the customary technology of power generation from fossil fuel and by hydroelectric means. One major difference between the management of nuclear power plants and that of conventional generating plants is the emphasis that should be placed on nuclear safety, quality assurance, the management of radioactive waste and radiological protection, and the accompanying national regulatory requirements. This Safety Guide highlights the important elements of effective management in relation to these aspects of safety. The attention to be paid to safety requires that the management recognize that personnel involved in the nuclear power programme should understand, respond effectively to, and continuously search for ways to enhance safety in the light of any additional requirements socially and legally demanded of nuclear energy. This will help to ensure that safety policies that result in the safe operation of nuclear power plants are implemented and that margins of safety are always maintained. The structure of the organization, management standards and administrative controls should be such that there is a high degree of assurance that safety policies and decisions are implemented, safety is continuously enhanced and a strong safety culture is promoted and supported. The objective of this publication is to guide Member States in setting up an operating organization which facilitates the safe operation of nuclear power plants to a high level internationally. The second objective is to provide guidance on the most important organizational elements in order to contribute to a strong safety

The nuclear safety research at JAERI is performed in accordance with the long term plan on nuclear research, development and use and the safety research yearly plan determined by the government and under close relationship to the related departments in and around the Nuclear Safety Research Center. The criticality accident having occurred in Tokai-mura in 1999 has been the highest level nuclear accident in Japan and ensuring safety in whole nuclear cycle is severely questioned. The causes of such an accident have to be clarified not only technical points but also organizational points, and it is extremely important to make efforts in preventing recurrence, to fulfill emergency plan and to improve the safety of whole nuclear fuel cycle for restoring the reliability by the people to nuclear energy system. The fields of conducting safety research are engineering safety research on reactor facilities and nuclear fuel cycle facilities including research on radioactive waste processing and disposal and research and development on future technology for safety improvement. Also, multinational cooperation and bilateral cooperation are promoted in international research organizations in the center to internationally share the recognition of world-common issues of nuclear safety and to attain efficient promotion of research and effective utilization of research resources.

2007-01-01

Japan finances research programs on photovoltaic conversion since 1974. Research in this domain is one of the 11 priorities of NEDO, the agency of means of the ministry of economy, trade and industry of Japan. The search for an abatement of production costs and of an increase of cells efficiency is mentioned in NEDO's programs as soon as the beginning of the 1990's. A road map has been defined which foresees photovoltaic energy production costs equivalent to the ones of thermal conversion by 2030, i.e. 7 yen/kWh (4.4 cents of euro/kWh). The use of new materials in dye-sensitized solar cells (DSSC) or organic solar cells, and of new structures (multi-junctions) is explored to reach this objective. The organic photovoltaic technology is more particularly considered for small generation units in mobile or domestic technologies. Japan is particularly in advance in the improvement of DSSC cells efficiency, in particular in the domain of the research on solid electrolytes. Europe seems more in advance in the domain of the new generation of organic solar cells. Therefore, a complementarity may be found between Japan and French teams in the domain of organic solar cells improvement through collaboration programs. (J.S.)

Japan Atomic Energy Research Institute carries out the safety research required for ensuring safety accompanying the development and utilization of atomic energy, dividing the roles with industrial circules, universities and other public research institutes. First, it carries out the research based on the yearly program of safety research, in which the subjects of safety research that the state should execute are decided. Next, it carries out a series of the safety verification test on atomic energy facilities entrusted by the state using the special account for power source development promotion countermeasures. Besides, it carries out the safety research on the specific subjects entrusted by outside organizations. The object and range of atomic energy safety at present are roughly divided into four fields, that is, nuclear power stations, nuclear fuel facilities, waste treatment and disposal, and environmental radioactivity. In order to advance the research effectively, in addition to the generalization department and the execution department, various committees are organized. In 1988, about 260 persons engaged in these four research fields, and the budget for fiscal year 1988 was about 17.4 billion yen. (K.I.)

Nuclear industry in Japan established a fixed foundation as a large complex system industry by elapsing about forty years since beginning of its development at top of 1930s. For Japan with little energy resources, nuclear power generation is one of essential choices because not only of keeping energy security but also of response to global warming problem such as global warming protection. Then, in order to intend to promote sound development of the nuclear industry in Japan, further upgrading of technology aimed at maintenance and improvement of safety and formation of understanding and agreement of the peoples must be established. Here was introduced a report on actual state of the nuclear industry in Japan in 1997 fiscal year prepared on February, 1999 by the Japan Atomic Industrial Forum. (G.K.)

Nuclear power is a vital energy supply source for both security and economy for such countries as Japan whose sources of energy are dependent on imported materials. This is the very reason why Japan gives her national priority to the improvement of nuclear power safety and reliability. As of the end of 1986, total nuclear power capacity owned and operated by private utility companies in Japan amounted to 24521 MW with 32 units sharing -- 19% of the total generating capacity. Moreover, during 1986 these units scored a remarkably high capacity factor of 76.2% and shared almost 28% of the nationwide electric power production, thereby contributing to a considerable saving of imported sources of energy. This outstanding record has been achieved by the parties concerned who dedicated themselves to furthering nuclear plant safety and reliability improvement. In this connection, this paper summarizes those key factors contributing to the good nuclear power plant performance of the Kansai Electric Power Company

2016-01-01

The Indonesia Nuclear Energy Act no. 10 of 1997 clearly stated that Nuclear Energy Regulatory Agency (BAPETEN) is the Nuclear Regulatory Body. This is the legal basis of BAPETEN to perform regulatory functions on the use of nuclear energy in Indonesia, including regulation, authorisation, inspection and enforcement. The Independent regulatory functions are stipulated in Article 4 and Article 14 of the Nuclear Energy Act no. 10 (1997) which require the government to establish regulatory body that is reporting directly to the president and has responsibility to control of the use of nuclear energy. BAPETEN has been start fully its functioning on January 4, 1999. In it roles as a regulatory body, the main aspect that continues and always to be developed is the safety culture. One of the objectives of regulatory functions is “to increase legal awareness of nuclear energy of the user to develop safety culture” (Article 15, point d), while in the elucidation of article 15 it is stipulated that “safety culture is that of characteristics and attitudes in organizations and individual that emphasise the importance of safety”.

White paper on nuclear energy, 1996

1996-01-01

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

After experienced nuclear disaster occurred on March 11, 2011, role of nuclear power in future energy share in Japan became uncertain because most public seemed to prefer nuclear power phase out to energy security or costs. Whether nuclear power plants were safe shutdown or operational, technologies were requisite for maintaining their equipment by refurbishment, partly replacement or pressure proof function recovery works, all of which were basically performed by welding. Nuclear power plants consisted of tanks, piping and pumps, and considered as giant welded structures welding was mostly used. Reactor pressure vessel subject to high temperature and high pressure was around 200mm thick and made of low-alloy steels (A533B), stainless steels (308, 316) and nickel base alloys (Alloy 600, 690). Kinds of welding at site were mostly shielded-metal arc welding and TIG welding, and sometimes laser welding. Radiation effects on welding of materials were limited although radiation protection was needed for welding works under radiation environment. New welding technologies had been applied after their technical validation by experiments applicable to required regulation standards. Latest developed welding technologies were seal welding to prevent SCC propagation and temper-bead welding for cladding after removal of cracks. Detailed procedures of repair welding of Alloy 600 at the reactor outlet pipe at Oi Nuclear Power Plants unit 3 due to PWSCC were described as an example of crack removal and water jet peening, and then overlay by temper-bead welding using Alloy 600 and clad welding using Alloy 690.

Military aspect of nuclear policy of Japan was outlined. In 1952 Prime Minister Yoshida asked to prepare production of weapons for rearmament and to establish Science and Technology Agency such as to overcome lack of science research budget and inefficiency of research and cooperation. Kaya and Fushimi proposed establishment of Atomic Energy Commission as recommendation of Science Council of Japan. In 1954 Nakasone proposed budget for nuclear energy with yen 235 million to construct reactor. In 1955 Japanese delegation participated in international conference on peaceful use of nuclear energy at Geneva and nonpartisan members proposed Atomic Energy Basic Law, which limited the use of nuclear technology to peaceful purposes, ensured three principles - democratic methods, independent management, and transparency - as the basis of nuclear research and promoted international co-operation. In 1956 Atomic Energy Commission and Science and Technology Agency were established with other organizations under this law. According to internal report in the age of Prime Minister Sato, nuclear policy in Japan would be (1) no holding nuclear weapon for the time being, (2) maintaining economic and technical potential of nuclear weapon production and (3) considering no restraint for this policy whether Japan participated in NPT or not. Fuel cycle program of Monju reactor and reprocessing for power production seemed to be deployed corresponding to (3) above. Irradiated blanket of Monju reactor could be reprocessed to produce highly purified plutonium suited for nuclear bombs. (T. Tanaka)

A comparative analysis between France and Japan on local governments' involvement in nuclear safety governance

International Nuclear Information System (INIS)

Sugawara, Shin-etsu; Shiroyama, Hideaki

2011-01-01

This paper shows a comparative analysis between France and Japan on the way of the local governments' involvement in nuclear safety governance through some interviews. In France, a law came into force that requires related local governments to establish 'Commision Locale d'Information' (CLI), which means the local governments officially involve in nuclear regulatory activity. Meanwhile, in Japan, related local governments substantially involve in the operation of nuclear facilities through the 'safety agreements' in spite of the lack of legal authority. As a result of comparative analysis, we can point out some institutional input from French cases as follows: to clarify the local governments' roles in the nuclear regulation system, to establish the official channels of communication among nuclear utilities, national regulatory authorities and local governments, and to stipulate explicitly the transparency as a purpose of safety regulation.

This work analyzes the Japan nuclear policy, in the frame of its foreign and safety policy in Pacific Asia, since the end of the cold war, especially the relations with the Usa and China. The Japan is a civil power because it has submitted the military institution to juridical restrictions and because it does not rely on the armed force to promote its national interests. The anti nuclear speech is joined with the acknowledgement of the dissuasion necessity, of the control of industrial processes and energy channels susceptible of military applications. Cultivating the ambiguity, the Japanese government can send a dissuasive message, perfectly legible, kind of communication of latent intimidation constituted by the virtual nuclear power of a state that takes part to the non proliferation treaty.

About 62 % of the energy supply in Japan depends on petroleum, and about 65 % of oil import comes from Persian Gulf. It is very important to ensure the supply of oil for the energy policy of Japan. For the purpose, the conversation between oil producing countries and oil consuming countries is necessary, but all the conversation carried out so far failed. The oil consumption in the world continued to decline, and the situation of oil market changed. The future situation of oil market largely depends on the development of substitute energy resources for oil. In order to ensure the supply of oil, the buyer's market must continue, therefore, effort must be continued to expand substitute energy and to promote energy saving. As the energy policy hereafter, various energy resources should be most effectively used in combination. In this compound energy age, the importance of nuclear power increases. The stable supply and economical efficiency of energy must be taken in consideration with the same weight. The only method to reduce the dependence on import is nuclear power, and this feature should be evaluated high. Nuclear power generation must be expanded hereafter. (Kako, I.)

In Japan, 4 nuclear power stations are under decommissioning and some nuclear fuel cycle facilities are expected to be decommissioned in the future. On the other hand, the safety regulation of decommissioning of nuclear facilities was changed by amending act in 2005. An approval system after review process of decommissioning plan was adopted and applied to the power stations above. In this situation, based on the experiences of the new regulatory system, the system should be well established and moreover, it should be improved and enhanced in the future. Nuclear Industry and Safety Agency (NISA) is in charge of regulation of commercial nuclear facilities in Japan and decommissioning of them is included. Japan Nuclear Energy Safety Organization (JNES) is in charge of technical supports for NISA as a TSO (Technical Support Organization) also in this field. As for decommissioning, based on regulatory needs, JNES has been continuing research activities from October 2003, when JNES has been established. Considering the 'Prioritized Nuclear Safety Research Plan (August 2009)' of the Nuclear Safety Commission of Japan and the situation of operators facilities, 'Regulatory Support Research Plan between FY 2010-2014' was established in November 2009, which shows the present regulatory needs and a research program. This program consists of researches for 1. review process of decommissioning plan of power reactors, 2. review process of decommissioning plan of nuclear fuel cycle facilities, 3. termination of license at the end of decommissioning and 4. management of decommissioning waste. For the item 1, JNES studied safety assessment methods of dismantling, e.g. obtaining data and analysis of behavior of dust diffusion and risk assessment during decommissioning, which are useful findings for the review process. For the item 2, safety requirements for the decommissioning of nuclear fuel cycle facilities was compiled, which will be used in the future review. For the item 3

The importance of safety culture in the safe and reliable operation of nuclear organizations is not a new concept. The greatest barriers to this area of research are twofold: (1) the definition and criteria of safety culture for a nuclear organization and (2) the measurement of those attributes in an objective and systematic fashion. This paper will discuss a proposed resolution of those barriers as demonstrated by the collection of data across nuclear and non-nuclear facilities over a two year period

Nuclear energy in postwar Japan and anti-nuclear movements in the 1950s.

The atomic bombings of Hiroshima and Nagasaki in August 1945 revealed the most destructive power to-date of man-made weapons. Their impact was so great that Japanese scientists thought that a bigger disaster could be prevented only if war was abolished. Thus they welcomed the international control of atomic energy. It was, however, only after the occupation that the Japanese general public began to learn about the horror of these atomic disasters due to the censorship imposed by the occupational forces. The hydrogen bomb test by the US in the Bikini atoll on March 1, 1954 renewed fears of nuclear weapons. The crew of a Japanese fishing vessel, the "Daigo Fukuryu Maru" (Lucky Dragon No. 5) suffered from exposure to radiation from the test. Even after the incident the US did not stop nuclear tests which continued to radioactively contaminate fish and rains in Japan. As a result, the petition movement for the ban of nuclear trials suddenly spread all over the country. By the summer of 1955 the number of the signatures grew to more than one third of Japan's population at the time. Under the strong influence of anti-nuclear Japanese public opinion the Science Council of Japan announced the so-called three principles of atomic energy: "openness," "democracy," and "independence" to ensure atomic energy was used for peaceful uses only. These principles were included in the Atomic Energy Basic Law established in December 1955. With this law, military uses of nuclear energy were strictly forbidden.

Japan has shown tremendous economic growth in the post-war period and is now one of the world's leading industrial countries. Japan has virtually no domestic oil or natural gas reserves and is the second-largest net importer of crude oil and largest net importer of liquefied natural gas in the world. Including nuclear power, Japan is only 16% energy self-sufficient (neglecting uranium imports). Japan's total primary energy demand in 2007 was 514 Mtoe. Oil is the most consumed energy resource in Japan (45% as of 2007), although its share of total energy consumption has strongly declined from 57% in 1990. Coal, with 22% (versus 17% in 1990), continues to account for a significant share of total energy consumption, although 99% of the coal must be imported. Natural gas (16%) and nuclear power (13%) are increasingly important sources. Total electricity production in Japan amounted to 1123 TW.h in 2007, with the largest share of 35% (up from 20% in 1990) from natural gas. The share of nuclear power is 32%, followed by coal (28%), oil (19%), hydro (9%) and other renewables (3%).

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

Japan's nuclear juggernaut

International Nuclear Information System (INIS)

Richner, S.

1984-01-01

A summary of nuclear energy in Japan is presented. Nuclear energy provides 17% of Japan's electricity but could provide much more. 25 more reactors (to add to the existing 27) are planned by 1995. The cooperation between Japanese government and industry and the economic assistance in building new plants means that these are not likely to be cancelled. Public acceptance of new plants has often been obtained by large cash employment inducements. Now, however, there is growing disillusionment when short-term well paid employment building the reactors is followed by unemployment when the reactor is in operation. Also there is a growing opposition to the storage of the nuclear waste. To maintain the growth of its nuclear industry Japan needs to export to provide a steady flow of big orders. (U.K.)

Current status and future prospects of nuclear energy utilization in Japan

International Nuclear Information System (INIS)

Kondo, S.

2006-01-01

Nuclear power is recognized as a safe, reliable and competitive energy source in Japan as Japan's 55 nuclear power plants supply about a third of the country's electricity and contribute to the rise in her degree of self-sufficiency in primary energy supply from 4% to 17%. It is also a practical and effective mean to observe the promise of the Kyoto Protocol to reduce CO2 emissions into atmosphere. The development of nuclear science and engineering, on the other hand, contributes not only to the advancement of science and technology in various fields but also to the improvement of health and living standards of the people as well as to the industrial prosperity through the application of radiation to medical diagnosis, cancer treatment, insect pest control, production of semi-conductors, radial tiers, etc. Major goal of current nuclear energy policy in Japan is to enrich the basic measures that compose the basis for the utilization of nuclear energy technologies in civil society and encourage academia and industries to innovate themselves to grapple the challenge, while sustaining the share of nuclear power in electricity generation after the year 2030 at the level equal to or greater than the current level of 30-40% based on the strategy to recycle uranium and plutonium from nuclear spent fuels, in addition to the expansion of the use of radiation technologies. Major policy areas are the improvement of institutional and financial arrangements to promote safe and effective utilization of nuclear energy technology including radiation technologies, the promotion of effective and efficient research and development activities, and the promotion of bilateral and multilateral cooperative activities necessary and or useful for facilitating these activities, in addition to nurturing the international political and institutional environment suitable for the sound promotion of nuclear energy utilization in the world. To pursue these goals, Japanese government and industries

Questions of whether past nuclear regulatory body of Korea is not a proper system to monitor and check the country's nuclear energy policy and utilization have been raised. Moreover, a feeling of insecurity regarding nuclear safety after the nuclear accident in Japan has spread across the public. This has stimulated a renovation of the nuclear safety regime in Korea. The Nuclear Safety and Security Commission (NSSC) was launched on October 26, 2011 as a regulatory body directly under the President in charge of strengthening independence and nuclear safety. This was a meaningful event as the NSSC it is a much more independent regulatory system for Korea. However, the NSSC itself does not guarantee an enhanced public acceptance of the nuclear policy and stable use nuclear energy. This study introduces the new NSSC system and its details in terms of organization structure, appropriateness of specialty, budget stability, and management system. (authors)

The March 2011 accident at the Fukushima Daiichi Nuclear Power Station turned Japan's energy policy on its head, shedding a harsh new light on Japan's energy policy and power supply system, and throwing into relief six major problem areas that had largely escaped scrutiny before the disaster. (1) Fragmentation of the power grid under the regional monopolies of Japan's 10 'general electric utilities' and the resulting failure to develop the kind of wide-area transmission system needed to transfer electricity from regions with a surplus to those suffering shortages. (2) The low electric supply capacity of entities other than the 10 regional utilities, making procurement of electric power from other sources difficult. (3) The lack of effective mechanisms for curtailing demand at times when a reliable electric supply is jeopardized. (4) The inability of customers to choose a power source or supplier. (5) The failure to manage the energy risks associated with a shutdown of Japan's nuclear power plants. (6) The urgent need to confront the risk of severe accidents and other hazards associated with nuclear power facilities. The pre-quake Strategic Energy Plan announced by the Democratic Party (DPJ) in 2010 put an emphasis on nuclear power as the mainstay of Japan's energy supply and offered little guidance for addressing these issues. The plan was subsequently rejected, and a new policy was announced by the DPJ to eliminate nuclear power from Japan's energy mix before 2040. The coalition agreement between the Liberal Democratic Party and the New Komeito Party, which defeated the DPJ in the December 2012 general election, backtracked from the 'zero nuclear power' policy, which constituted an important shift from the nuclear-dependent policies of the pre-Fukushima era. In April 2013, the LDP government of Prime Minister Shinzo Abe approved a document titled Policy on Electricity System Reform emphasizing the need to make use of a wider range of energy sources, and in April

Due to tsunami triggered by the Great East Japan Earthquake, the operating and refueling reactor facilities at Fukushima Dai-ichi and Dai-ni Nuclear Power Plants caused a nuclear hazard. Given the fact, Japanese electric power companies voluntarily began to compile various urgent measures against tsunami. And then the Nuclear and Industrial Safety Agency (NISA) ordered the licensees to put into practice the voluntarily compiled urgent safety measures, in order to ensure the effectiveness of the means for recovering cooling functions along with avoiding the release of radioactive substances to the possible minimum, even if a huge tsunami following a severe earthquake hits nuclear power plants. The following describes the state and the effect of the urgent safety measures implemented for 44 reactors (under operation) and 1 reactor (under construction) in Japan and also describes the measures to be implemented by the licensees of reactor operation in the future.

Public acceptance of nuclear power in Japan

Japan has a fragile energy supply structure, with 84% of its energy depending on import; for example, 99.6% of the oil comes from overseas, which makes Japan's economic base rather vulnerable. In order to ensure constant energy supply, it is indispensable to diversify the energy sources and to create indigenous energy. In view of this, nuclear energy is considered to be the main alternative to crude oil because it has several advantages over other energy sources, such as stable supply of uranium and the fact that it is compatible with efforts to find solutions to global environmental problems. However, since the general public is not familiar with nuclear technology, it is difficult to get the understanding and co-operation of people. In view of this, public relations activities providing information on the need and safety of nuclear power generation have been performed. As a result, in recent years, about 70% of the people came to recognize the need for nuclear power generation. Although people's recognition of this need has increased substantially, it is still difficult for them to accept the construction of nuclear facilities, because of their anxiety regarding the safety of such plants and the lack of information by the government and electric utilities. This makes the acquisition of new sites for nuclear power plants difficult, so that the time required for developing such plants becomes longer. In order to eliminate people's anxieties, both the government and electric utilities should provide accurate information, at the proper time and using a method that makes it easy for the people to understand the problems involved. It is also important for the government and the electric utilities to listen carefully to the opinions and questions of people and to increase friendly communications with them. The government, electric utilities and constructors of nuclear facilities have to co-operate in order to improve the measures taken to gain public acceptance of

Sandia National Laboratories (SNL) and Japan Nuclear Cycle Development Institute (JNC) have conducted an extensive emergency response planning study of the safety of the sea transport of plutonium for JNC. This study was conducted in response to international concerns about the safety of the marine transport of PuO2 powder that began with the sea transport of plutonium powder from France to Japan in 1992 using a purposebuilt ship. This emergency response planning study addressed four topics to better define the accident environment for long-range sea transport of nuclear materials. The first topic is a probabilistic safety analysis that evaluates the technical issues of transporting plutonium between Europe and Japan. An engine-room fire aboard a purposebuilt ship is evaluated as the second topic to determine the vulnerability and safety margin of radioactive material packaging for plutonium designed to meet International Atomic Energy Agency (IAEA) standards. The third topic is a corrosion study performed for generic plutonium packaging to estimate the time required to breach the containment boundary in the event of submersion in seawater. The final study topic is a worldwide survey of information on high-value cargo salvage capabilities from sunken ships. The primary purpose of this overall emergency response planning study is to describe and analyze the safety of radioactive material transportation operations for the international transportation of radioactive materials by maritime cargo vessels

The structure of energy consumption in Japan is heavily dependent on imported oil, therefore Japan has been making its greatest effort in developing nuclear power among other alternatives of oil. The capacity factor of the nuclear power plants in Japan marked 76% in FY 1986, exceeding 70% level for the past several years. The share of nuclear power is expected to increase steadily in the future. Future scale of the nuclear power generation is projected as 62,000 MW in year 2000 and as 137,000 MW in 2030. Nuclear power is expected to produce 58% of the nation's total power generation in 2030. Under the present circumstances, Janpan is executing a nuclear energy policy based on the following guidelines: 1. Promoting the safety advancement program; 2. Improving LWR technologies; 3. Program on use of plutonium in thermal reactors; 4. Advanced thermal reactors (ATRs); 5. Promotion of FBR development; 6. Nuclear fuel cycle. (Liu)

Based on results of activities of committee on seismic safety of nuclear power plants (NPPs) of Japan Association for Earthquake Engineering, which started activities after Chuetsu-oki earthquake and then experienced Great East Japan Earthquake, (under close collaboration with the committee of Atomic Energy Society of Japan started activities simultaneously), and taking account of further development of concept, agenda on nuclear safety were proposed from earthquake engineering. In order to prevent recurrence of nuclear disaster, individual technical issues of earthquake engineering and comprehensive issues of integration technology, multidisciplinary collaboration and establishment of technology governance based on them were of prime importance. This article described important problems to be solved; (1) technical issues and mission of seismic safety of NPPs, (2) decision making based on risk assessment - basis of technical governance, (3) framework of risk, design and regulation - framework of required technology governance, (4) technical issues of earthquake engineering for nuclear safety, (5) role of earthquake engineering in nuclear power risk communication and (6) importance of multidisciplinary collaboration. Responsibility of engineering would be attributed to establishment of technology governance, cultivation of individual technology and integration technology, and social communications. (T. Tanaka)

Recently, the Government of Japan announced macroflame of GDP growth rate, crude oil cost, population, economic actions and demand of energy from the present to 2030. On the view point of decrease of population, economy is not affected by it and labor shortage will be supplied by advanced technologies. Accordingly, many economists expect increase of GNP and economy. However, energy demand will increase until 2020 and then decrease. Four new atomic power plants to be building will operate until 2010 and six plants will be constructed until 2030. Discharge of CO 2 will increase until 2020 and then decrease depends on energy demand. The outlook of nuclear energy contains two important assumptions, 85% of rate of operation and 60 year of operation time. The fuel cycle is very important in the world. (S.Y.)

The present report discusses the current status of Japan's licensing system and legislation concerning reactor decommissioning operations. Besides Japan is working to promote worldwide nuclear safety research. However, developing nuclear safety regulations that are uniformely applicable is a difficult job due to big differences in geographical, political, economical, and technological conditions. (CW) [de

Positioning of Nuclear in the Japanese Energy Mix

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

Japan: The institute for the economy of energy recommends a quick re-start of nuclear reactors

The Japanese Institute for the Economy of the Energy (IEEJ) considers that the sooner the nuclear reactors will re-start, the better the Japanese economy and environment will be. The 48 Japanese reactors were stopped after the Fukushima accident and their restart is linked to the implementation of new measures for reinforcing safety. Until now only 2 reactors Sendai 1 and Sendai 2 have been allowed to re-start. The procedure for the safety assessment of the reactors is slower than expected. A study shows that only 7 reactors may be allowed to re-start before march 2015 and a total of 19 units may be operating in march 2016. In this scenario 2% of the electricity will come from nuclear energy in 2014 and 15% in 2015, natural gas imports will still be necessary for the production of electricity and their global cost is estimated to reach 56 billions euros while Japan's rate of energy independence will drop by 4.6%.

Nuclear safety and energy supply security: conflict or goal?

International Nuclear Information System (INIS)

Kutas, S.

2006-01-01

Energy generation and safety problems at the nuclear power plant have been analysed. Nuclear power plants are operated on the commercial basis in many countries today. Safety and security in energy generation and distribution is a complex problem. Energy supply reliability, security energy price and other issues should be co-ordinated and solved at the same time. Decentralisation and deregulation means new challenges for regulatory bodies and assurance of security. International co-operation in this field is very important. Western European Nuclear Regulators' Association (WENRA) consolidates efforts of regulatory bodies of European countries in order to harmonize approaches of nuclear safety. Nuclear Safety, and security of energy supply is the task and goal at the same time. (author)

Nuclear energy and its public acceptance in Japan

International Nuclear Information System (INIS)

Matsui, A.

1981-01-01

Heavily dependent on imported oil, Japan with a nuclear park of 22 working power plants meets with public opposition for its nuclear program extension. Consequently, the foreseen 53.000 MWe installed nuclear capacity will be reduced to some 30.000 MWe for the beginning of the nineties. The paper analyses the different varieties of factors clogging the development of nuclear energy such as social, psychological and economic aspects and describes the information campaigns of concerned milieus in order to deal with this situation and comments the final results of these actions. Two concrete examples of confrontation of the public with the authorities on the approval of new nuclear power plant projects are presented. (AF)

1980-01-01

The pending repair work of the shielding of the nuclear ship ''Mutsu'' was started at long last, and the development of nuclear ships in Japan is to be accelerated again. The Agency intends to exert more efforts to execute the repair of shielding and the works of the general inspection on safety for ''Mutsu'' rapidly and surely and to attain the expected objective. The energy situation in the world is still in confusion, and all countries, advanced and developing alike, are carrying out the researches to develop and utilize substitute energy. Especially large expectation is entertained in atomic energy which can fill the energy gap for the time being, and the policy to promote positively the improvement of safety and the development of the application to new fields is being taken. In such situation, the Atomic Energy Commission clarified the policy to positively promote the research and development on nuclear ships including the design of new nuclear reactors considering their necessity to relax the restriction of energy supply. As for the ''Mutsu'', the AEC insists that the repair should be completed and the operation test must be executed urgently. Concerning the organization for the research and development, the Agency is to undertake the solution of the pending problems related to the ''Mutsu'', and also is required to have the functions of the research and development aiming at the improvement of the economy and reliability of nuclear ships. In this report, the works of the Agency carried out in 1979 are described. (Kako, I.)

Toward improvements of the education concerning radiation, radioactivity, and nuclear energy in high schools in Japan

Matsuura, Tatsuo

1996-01-01

Despite the high scientific and technical level of research and practical applications of radiation, radioactivity, and nuclear energy in Japan, the level of education concerning these matters at primary school and junior and high schools seems to be considerably behind the world, according to a recent comparative survey among six European countries and Japan. It has also been found that the description of these matters in current textbooks of science and social studies in senior high schools in Japan is generally not satisfactory, both in scope and in correctness. There are many reasons for this observation. One is the fact that many Japanese people including writers of textbooks have an excessive fear for radiation and radioactivity, and consequently are critical of the use of nuclear energy. Another is that Japanese teachers also have similar feeling and tend to avoid teaching about such controversial subject. This comes from the educational policy of Monbusho, Ministry of Education, Science and Culture; the nuclear-related matters are not being given an appropriate educational position, despite their importance in the national energy policy determined by the Atomic Energy Commission of Japan. In addition, there are several unfortunate educational circumstances. These include, limitations of hours of teaching allotted to the subject of science, the system of choosing curricula among several menus in the subject, the shortage of experimental instruments available in classroom, the severe safety regulation in handling even a very small amount of radioactivity, extraordinary fear for radiation and radioactivity by students, teachers, and their supervisors, the rare appearance of these topics in the problems at the entrance examination of universities. This paper discusses various ways to correct the situation and reports on our recent activities for improving means of education such as textbooks and the official guidelines. (J.P.N.)

Energy problems and nuclear power in Japan

International petroleum situation maintains the balance between demand and supply for the time being, but hereafter, it seems to be more serious and uncertain. Japanese economy tided over the first oil crisis with difficulty, and moreover, responded to the second oil crisis after the Iranian revolution somehow or other. But oil price has continued to rise, and the acceleration of inflation, the serious depression of businesses and electric power crisis are feared. In Japan where the dependence on imported petroleum is as high as 75%, it is necessary to establish the long term energy policy making energy saving and the development of substitute energy as its mainstay. In August, 1979, the report concerning the interim prospect of long term energy demand and supply was made. Largest efforts will be exerted to reduce the oil import. Then the total demand of energy in 1985 will be 582 million kl calculated in terms of petroleum. The law concerning energy saving was enacted in June, 1979. As the substitute energy, imported coal, LNG and nuclear power generation should be adopted. However, in order to put these energies in practical use, many problems to be solved remain. 21 nuclear power plants of 14.9 million kW capacity are in operation, and provide with 12% of total power generation installations. 30 million kW of nuclear power generation will be attained by 1985.

When disaster struck at the Fukushima Daiichi Nuclear Power Plant in March 2011, the IAEA offered immediate assistance to the Plant operators and the Japanese authorities as they tried to regain control over the reactors. We began sharing verified information about the accident with the world and helped to channel international assistance to Japan. A high priority was to do everything we could to help ensure the safety of the people of Japan, especially those in Fukushima Prefecture who were most affected by the crisis. I went to Japan a few days after the accident to meet then Prime Minister Kan. I assured him that Japan could count on the support of the entire international community and stressed the need for full transparency. I sent a number of expert teams to assist in areas such as radiological monitoring, food safety, and analysis of the situation at the Fukushima Daiichi Plant. Four IAEA teams undertook measurements in the Fukushima region, both inside and outside the 20 km evacuation zone. An expert on marine monitoring programmes from the IAEA Environmental Laboratories helped to monitor seawater. Joint teams from the IAEA and the UN Food and Agriculture Organization advised local authorities on technical issues related to food safety and agricultural countermeasures. Some important environmental readings at key points in the unfolding crisis were taken by IAEA experts. Our presence helped to provide reassurance to the people of Japan at a very critical time. It is now one year and nine months since the accident. In that time, we have continued to work closely with Japan. Today, I will sign an important document with Governor Sato of Fukushima Prefecture on our cooperation in the coming years. The IAEA will work closely with the Prefecture in radiation monitoring and decontamination. We will also implement human health projects with Fukushima Medical University.

The nuclear safety cultural competency model should be supplemented through a bottom-up approach such as behavioral event interview. The developed model, however, is meaningful for determining what should be dealt for enhancing safety cultural competency of nuclear organizations. The more details of the developing process, results, and applications will be introduced later. Organizational culture include safety culture in terms of its organizational characteristics.

Japan's new energy policy

International Nuclear Information System (INIS)

2014-11-01

Japan's energy policy is undergoing fundamental changes. The accident at TEPCO's Fukushima Daiichi nuclear power plant questions the future contribution of nuclear power in the national energy mix. Growing imports of fossil fuels to replace the lost nuclear capacity inflated energy prices and raise economic and energy security challenges. At the same time, the US shale gas and oil revolution is reshaping the global energy scene. Japan expects to take advantage of the trend to eliminate the 'Asian premium' on natural gas prices and expand cheaper natural gas consumption. These developments have driven the Government of Japan to review its energy policy from scratch and adopt a new Strategic Energy Plan. This new policy has far reaching implications for gas and coal development in Japan but also for the international markets as Japan is the world's largest LNG importer and the second largest coal importer. This document summarizes the key findings of a new report by CEDIGAZ 'Japan's new energy policy: In search for stable and competitive energy supply'. The report analyzes the current changes taking place on the gas and coal markets in Japan, in light of the new energy policy adopted in April 2014, and in particular the decision to restart safe nuclear power plants and push forward electricity market reforms

Rearing of talented persons in the area of nuclear energy is one of the important works in Japan Atomic Energy Research Institute. In this report, the present situations and future schedules of international human cooperation in this area wsere summarized. First, the recent activities of International Nuclear Technology Center were outlined in respect of international human cooperation. A study and training course which was started in cooperation with JICA and IAEA from the middle of eighties and the international nuclear safety seminar aiming at advancing the nuclear safety level of the world are now being put into practice. In addition, a study and training for rearing talented persons was started from 1996 to improve the nuclear safety level of the neighbouring countries. The activities of the nuclear research interchange system by Science and Technology Agency established in 1985 and Bilateral Co-operation Agreement from 1984 were explained and also various difficulties in the international cooperation were pointed out.

An analysis was made on the potential and cost of reducing carbon dioxide (CO{sub 2}) emissions from Japan`s long-term energy systems by using the MARKAL model, developed in the Energy Technology Systems Analysis Programme (ETSAP) of International Energy Agency (IEA). Assuming future growths of GDP, the demand for energy services was estimated for the analytical time horizon 1990-2050. Assumptions were made also on prices and availability of fossil fuels, and on availability of nuclear and renewable energy. CO{sub 2} emissions and system costs were compared between energy demand and supply scenarios defined with different assumptions on nuclear energy, a CO{sub 2} disposal option, and natural gas imports. Main results were as follows. Without nuclear energy, the CO{sub 2} emissions will hardly be reduced because of the increases of coal utilization. CO{sub 2} disposal will be effective in reducing the emissions, however at much higher costs than the case with nuclear energy. The expansion of natural gas imports alone will not reduce the emissions at enough low levels. (author)

Since three Laws on the nuclear power were published 45 years has passed. Now, development on nuclear power in Japan is at an emergent state. In Japan, 51 units of commercial nuclear reactors with 44.917 GW are in operation, occupy about 37% of total electric power generation, and is positioned at an essential basic energy source supporting economical society in Japan. However, an accident occurred at Tokai Works of the JCO Co., Ltd., one of the uranium reconversion company, on September 30, 1999, was the first critical accident in Japan, and became the worst case in history on development of nuclear power in Japan, because of forming three heavy radiation disabled persons (One of them was dead) in its operators. This was a big crisis with relation to existence on development of nuclear power in Japan, by which anxiety and distrust of the Japanese against the nuclear power were amplified rapidly. On the other side, for Japan short in energy sources and of a big energy consumption, in order to intend for a long term to carry out energy security, global environmental conservation, and sustainable maintenance of essential growth, it remains to be one of important optional methods to further promote nuclear power generation and to establish nuclear fuel cycle. Here were described on progress on peaceful applications of nuclear power in Japan, progress on the field of nuclear power in Japan (from 1955 to 1999), progress on Tokai nuclear power station, introduction of nuclear power generation and effort on its domestic production.

History and structure of Japan-US nuclear alliance

'Japan-US nuclear alliance' for civil use of nuclear energy was used here as technical term for the state Japanese commercial power plants were all water-cooled reactors under the US nuclear engineering umbrella and US admitted Japanese development of all 'SNT: sensitive nuclear technology' in the area of nuclear fuel cycle. 'Japan-US alliance' was used for various areas closely related with national security while 'Japan-US nuclear weapon alliance' was for military use of nuclear energy such as nuclear weapon (transport methods included) and counter weapon system. Military and civil use of nuclear energy relied fundamentally on common technical bases and especially nuclear fuel cycle related technologies were directly connected to both uses and called 'SNT'. Japanese nuclear policy sticking to SNT might come from the axiom: nuclear engineering for national security, that meant Japan refrained from nuclear arms but maintained technical and industrial potential of nuclear arms. This could be called 'nuclear arms standby strategy' and derived from compromise of both countries to play role of stabilizer of 'Japan-US alliance'. History of Japanese nuclear power development could be well understood as formation process of 'Japan-US nuclear alliance'. If Fukushima Daiichi accident forced nuclear power to phase out, nuclear fuel cycle would be obliged to terminate. This meant failure of the axiom and dissolution of 'Japan-US nuclear alliance'. (T.

A goal of the 21. century is for society to pursue 'sustainable economic development and prosperous life by recycling resources', thus rejecting 'development based on the waste of resources'. For Japan, which has limited energy resources, it is important to secure safe, inexpensive, environmentally friendly energy resources having long-term availability. To contribute to long-term energy security and solve global environmental issues, and to create advanced competitive science and technology, the Japan Atomic Energy Agency (JAEA) was established by integrating the Japan Atomic Energy Research Institute (JAERI) and the Japan Nuclear Cycle Development Institute (JNC) in October 2005. JAEA is endeavoring to establish nuclear fuel cycles, to contribute to social improvement through hydrogen production initiated by atomic energy, and to pursue research and development of thermonuclear fusion and quantum beam technology. This paper reviews the main R and D activities of JAEA. The structure of the paper is the following: 1. Introduction; 2. Japan Atomic Energy Agency; 3. Efforts to Commercialize the Fast Reactor Cycle; 4. Monju Progress; 5. Geological Disposal of High-Level Radioactive Waste R and D; 6. High Temperature Gas-Cooled Reactor System R and D; 7.

Basic Science and Engineering Research; 12. Contribution to the Enhanced International Nonproliferation Regimes; 13. Conclusions. To summarize, JAEA will promote the above R and D activities, addressing the following commitments: - On problems that atomic energy faces, we shall extend technical assistance in response to the government and the industrial sectors. - We shall produce technical options to attain political goals to secure medium to long-term stable energy supplies and to solve global environmental issues. - With the high potentials of atomic

Building a new energy network in North East Asia. A perspective from post-Fukushima Japan

Shibutani, Yu

2012-01-01

The accident at Fukushima Daiichi Nuclear Power Station (NPS) has accelerated Japan's drive for less dependence on nuclear and fossil energy and more green renewables, which inevitably require a new energy strategy. In this paper, a new strategic scenario for moving 'beyond a single economy' is proposed to incorporate Japan with the North East Asian (NEA) energy market in regards to its electricity grid and natural gas pipeline network while preserving nuclear power by strengthening safety. Suggestions are also made that Japan should open more doors for new comers in a manner of open-access towards member economies of NEA. However, there are persistent geopolitical constraints and risks in NEA. The connection of Japan's energy network to its regional neighbors would avoid the tendrils and tentacles of geopolitics that wrap around NEA, and subsequently provide opportunities to build on common energy interests.

Seawater desalination plants have been installed at several nuclear power plants in Japan in order to satisfy the regulations for nuclear plant installation. This has been done where there is a limited source of water due to the geological conditions. These desalination plants are being operated to ensure supplemental water by using thermal or electrical energy from the nuclear power plant. The desalination plant is not operated continuously during the year because the major function of the plant is to ensure the supply of supplemental water for the nuclear power plant. Regarding maintenance of the desalination plant, some piping was exchanged due to corrosion by high temperature seawater, however, the desalination plants are being operated without any trouble as of today. Recently, the development of innovative and/or small reactor designs, that emphasise safety features, has been promoted in Japan to use for seawater desalination and for installation in developing countries. An advanced RO system with lower energy consumption technology is also being developed. Furthermore, some Japanese industries and universities are now very interested in nuclear desalination.

Safety policy for nuclear power development

International Nuclear Information System (INIS)

Uchida, Hideo

1987-01-01

The report discusses various aspects of the safety policy for nuclear power development in Japan. Nuclear power development over three decades in Japan has led to operating performance which is highly safe and reliable. This has been appreciated internationally. Discussed here is the Japanese basic safety policy for nuclear power development that is essential first to design, manufacture and construction using high technology. The current careful quality assurance and reliable operation management by skilled operators are relied upon, on the basis of the fact that measures to prevent abnormal events are given first priority rather than those to mitigate consequences of abnormal events or accidents. Lessons learned from accidents and failures within or outside Japan such as the TMI accident and Chernobyl accident have been reflected in the improvement of safety through careful and thorough examinations of them. For further improvement in nuclear safety, deliberate studies and investigations on severe accidents and probabilistic safety assessment are considered to be important. Such efforts are currently being promoted. For this purpose, it is important to advance international cooperation and continue technical exchanges, based on operation experience in nuclear power stations in Japan. (Nogami, K.)

Yanagisawa, Kazuaki

2007-01-01

In Japan, so-called a formal nuclear policy; The Framework for Nuclear Energy Policy is built up by Japan Atomic Energy Commission at every 5-year, in which not only a conventional light water reactor (LWR) but also a fast breeder reactor (FBR), HTGR and a fusion reactor (FR) is referred as a prominent candidate of long-term (<100 years) nuclear energy source. The policy makers might have multi-purpose scenarios for a future of innovated nuclear energy systems through results of various discussions at their level. According to long-term nuclear knowledge management, the author made ex ante evaluation of HTGR known as the intellectual assets of JAERI 1, from the viewpoint of hypothetical benefits under conditions of substantial uncertainty. Nuclear knowledge management (NKM) is an integrated, systematic approach to identifying, managing and sharing an organization's nuclear knowledge, and enabling persons to create new nuclear knowledge collectively and thereby helping achieve the objectives. NKM identifies, optimizes, and actively manages intellectual assets either in the form of explicit knowledge held in intangible products or tacit knowledge possessed by individuals or communities in the nuclear fields. In the present study the authors wish not only to show the validity of long-term NKM as a key factor of HTGR but also to assess their hypothetical benefits through the year 2050 under conditions of substantial uncertainty. It should be stressed that those factors are important intellectual assets of JAERI developed to date. Additionally, in the Framework for Nuclear Energy Policy constructed up by the Japan Atomic Energy Commission, a LWR, a fast breeder reactor (FBR), a HTGR, and a fusion reactor (FR) are all defined as eligible and prominent candidates for long-term nuclear energy sources. In this sense, we estimate here a direct market creation of (1) hydrogen energy production and (2) electricity generation, by commercialized HTGR through the year 2050 with

Although the Japanese set out to achieve the peaceful uses of atomic energy in 1956, the question of public acceptance took on serious proportions only as the development of nuclear power moved toward commercial application. A string of reactor troubles over the past few years complicated the question apparently to the point where it could scarcely be worse. It is not possible to deal with opposition movements in Japan without taking into account the background of the special national sentiment born of the people's experience of the atomic bombings, but it is also true that the people's deep-going fears of atomic energy have been increased by sensational newspaper reports, as well as internetional attacks by the opponents of nuclear development. Added to this, the ''Mutsu'' incident and other troubles have given the people distrust of the whole nuclear administration and those responsible for nuclear regulation. but, at the same time, the oil crisis of 1973 brought about an awakening of the people to the need for the development of nuclear power to solve Japan's energy problems, for Japan is seriously lacking in natural resources. An influential newspaper took samplings of public opinion in 1975 which revealed that, while 48 percent of the people expressed fears of atomic energy, 70 percent, including those who had some misgivings but still took the need for granted, said that Japan has no choice but to depend on nuclear power. The Government and industry have made long-range projections on nuclear power generation, forecasting that it will expand to 25 percent of all power generating plants by 1985, and to 35 percent by 1990. The gravest problem to be solved if this projected scale of nuclear development is to be achieved is the shortage of adequate plant sites. This can not be solved unless every effort is made to dispel the general feeling of mistrust mentioned, and to make sure that the development of nuclear power is socially accepted. It is hoped that the

This project aims to do research on forecasts of energy demand structure and electricity generation cost in each power plant in Japan in the 21st century, considering constructing successful FBR scenario. During the process of doing research on forecasts of energy demand structure in Japan, documents published from organizations in inside and outside of Japan were collected. These documents include prospects of economic growth rate, forecasts of amount for energy supply and demand, the maximum amount of introducing new energy resources, CO2 regulation, and evaluation of energy best mixture. Organizations in Japan such as Economic Council and Japan Energy Economic Research Institute have provided long-term forecasts until the early 21st century. Meanwhile, organizations overseas have provided forecasts of economic structure, and demand and supply for energy in OECD and East Asia including Japan. In connection with forecasts of electricity generation cost in each power plant, views on the ultimate reserves and cost of resources are reviewed in this report. According to some views on oil reserves, making assumptions based on reserves/production ratio, the maximum length of the time that oil reserves will last is 150 years. In addition, this report provides summaries of cost and potential role of various resources, including solar energy and wind energy; and views on waste, safety, energy security-related externality cost, and the price of transferring CO2 emission right.

What is nuclear power in Japan?

Suzuki, Toshikazu

The aggressive use of such non-fossil energy as the atomic energy with high power density and energy production efficiency is an indispensable choice aiming at the low-carbon society. There is a trial calculation that the carbon dioxide emission of 40000 ton can be suppressed by nuclear power generation by one ton of uranium. The basis of nuclear research after the Second World War in Japan was established by the researchers learnt in Argonne National Laboratory. In 2010, NPPs under operation are 54 units and the total electric generating power is 48.85GW. The amount of nuclear power generation per person of the people is 0.38kW in Japan, and it is near 0.34kW of the United States. However, the TMI accident and the Chernobyl disaster should have greatly stagnated the nuclear industry of Japan although it is not more serious than the United States. A lot of Japanese unconsciously associate a nuclear accident with the atomic bomb. According to the investigation which Science and Technology Agency carried out to the specialist in 1999, ``What will be the field where talent should be emphatically sent in the future?'' the rank of nuclear technology was the lowest in 32 fields. The influence of the nuclear industry stagnation was remarkable in the education. The subject related to the atomic energy of a university existed 19 in 1985 that was the previous year of the Chernobyl disaster decreased to 7 in 2003. In such a situation, we have to rely on the atomic energy because Japan depends for 96% of energy resources on import. The development of the fuel reprocessing and the fast breeder reactor has been continued in spite of a heavy failure. That is the only means left behind for Japan to be released from both fossil fuel and carbon dioxide.

This article describes the advantages of nuclear energy for Japan. In 1997 the composition of the total primary energy supply (TPES) was oil 52.7%, coal 16.5%, nuclear 16.1% and natural gas 10.7%. Nuclear power has a significant role to play in contributing to 3 national interests: i) energy security, ii) economic growth and iii) environmental protection. Energy security is assured because a stable supply of uranium fuel can be reasonably expected in spite of dependence on import from abroad. Economic growth implies the reduction of energy costs. As nuclear power is capital intensive, the power generation cost is less affected by the fuel cost, therefore nuclear power can realize low cost by favoring high capacity utilization factor. Fossil fuels have substantial impacts on environment such as global warming and acid rain by releasing massive quantities of CO 2 , so nuclear power is a major option for meeting the Kyoto limitations. In Japan, in 2010 nuclear power is expected to reach 17% of TPES and 45% of electricity generated. (A.C.)

Efforts at nuclear safety research have expanded year by year in Japan, in term of money and technical achievement. The Atomic Energy Commission set last year the five year nuclear safety research program, a guideline by which various research institutes will be able to develop their own efforts in a concerted manner. From the results of the nuclear safety research which cover very wide areas ranging from reactor engineering safety, safety of nuclear fuel cycle facilities, prevention of radiation hazards to the adequate treatment and disposal of radioactive wastes, AIJ hereafter focuses of LWR engineering safety and prevents two articles, one introducing the current results of the NSSR program developed by JAERI and the other reporting the LWR reliability demonstration testing projects being promoted by MITI. The outline of these demonstration tests was reported in this report. The tests consist of earthquake resistance reliability test of nuclear power plants, steam generator reliability tests, valve integrity tests, fuel assembly reliability tests, reliability tests of heat affected zones and reliability tests of pumps.

Nuclear power safety

1988-01-01

The International Atomic Energy Agency, the organization concerned with worldwide nuclear safety has produced two international conventions to provide (1) prompt notification of nuclear accidents and (2) procedures to facilitate mutual assistance during an emergency. IAEA has also expanded operational safety review team missions, enhanced information exchange on operational safety events at nuclear power plants, and planned a review of its nuclear safety standards to ensure that they include the lessons learned from the Chernobyl nuclear plant accident. However, there appears to be a nearly unanimous belief among IAEA members that may attempt to impose international safety standards verified by an international inspection program would infringe on national sovereignty. Although several Western European countries have proposed establishing binding safety standards and inspections, no specific plant have been made; IAEA's member states are unlikely to adopt such standards and an inspection program

Social contention about safety of nuclear power plant

1978-01-01

In Japan, the contentions and arguments on the safety of nuclear power generation have been active since its first introduction, and these are greatly influenced by the nation's experiences of atomic bombs in Hiroshima, Nagasaki, and Bikini. As the result, the attitude of peoples toward the acceptance of nuclear power plants is significantly different from that in other countries. The situation in Japan of social contentions about nuclear power safety is explained in two aspects: acceptance of the safety, by peoples and Japanese pattern of safety contentions. In both upstream and downstream of nuclear power generation, not only the safety but also the right or wrong for nuclear power generation itself is discussed. The problem of nuclear power safety has gone into the region beyond the technological viewpoint. The pattern of safety contentions in Japan is the entanglement of three sectors; i.e. local people, labor unions and political parties, enterprises and administration, and intellectuals. (Mori, K.)

About 4.5 years has passed after Fukushima Daiichi NPP accident. Only one nuclear power plant restarted in Japan, and also the nuclear fuel reprocessing plant in Rokkasho hasn't begun a commercial operation yet. The Agreement for Cooperation Concerning the Civil Use of Atomic Energy between the U.S. and Japan the present revision agreement on July 17th, 1988 comes into force and the validated-period is 30 and reaches a due-date in July, 2018. Except for a few countries such as German and Switzerland, the nuclear power plant construction has expansionary trend. Especially, the determination is remarkable among the growing countries such as Asia and the middle-east. There are many countries which started nuclear power plant construction for the first time such as Vietnam, UAE, and Turkey. In these various countries, the merits of the nuclear power plant is admitted as the rapid increase and the countermeasure of the energy-need against the global warming like an advanced and is being proceeded with, being powerful in the form of the state project. With it, the countries such as France, the Russia the U.S., Korea, and China which have a nuclear power plant technology are vigorous and have completion for export plants. With the Japanese nuclear power plant export policy which the government proceeds with, there are not few psychological drags and ethical sense of discomforts among the people but the export of the nuclear power plant as the basic key industry in our country, and the high level waste reprocessing, this need the Japan-U.S. nuclear energy agreement. The agreement can be ended by giving notice with the document from before by 6 months in the expiration date but unless this preliminary notice is accomplished, the potency of the agreement continues.

2013-01-01

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 [fr

The U.S. nuclear safety assistance activities have had a direct and substantial impact on improving safe operations of 67 Soviet-designed commercial nuclear power plants in Armenia, Bulgaria, Czech Republic, Hungary, Kazakhstan, Lithuania, Russia, Slovakia, and Ukraine. The U.S. Department of Energy worked with these host countries both to improve safe nuclear operations and in some cases assist in plant shutdown. Independent international safety reviews have identified significant progress in the Eastern European countries to improve the safety of their nuclear power plants since the early 1990s. In addition, all of the probabilistic risk assessments conducted at these plants show a major reduction in the frequency of core damage accidents since U.S. assistance to improve safety at these reactors began. Improved operational safety follows from the combined efforts to improve operator performance. These efforts include providing simulators for operators to practice handling emergency scenarios, developing emergency operating instructions that guide operators calmly through emergencies, providing safety parameter display systems that give operators immediate graphical information on the status of plant systems and training the operators on the safety basis for the plants they operate

At present, a half century has elapsed since the discovery of nuclear fission, and atomic energy has taken the position of basic energy already, accordingly the development and utilization of atomic energy is very important as the energy source which can supply energy for long term economically and stably. Along the long term plan of atomic energy development and utilization decided in 1987, Japan Atomic Energy Research Institute (JAERI) advanced the research and development, thus it has borne the role as the nucleus general research institute in atomic energy fields. It has exerted efforts to obtain the understanding and trust of the nation on atomic energy, and has promoted the pioneering project research, such as safety research, high temperature engineering test and research, the research and development of nuclear fusion, the research on radiation utilization and the research and development of nuclear-powered ships. In the safety research, in order to contribute to the further rooting of LWRs and the establishment of nuclear fuel cycle, the research on the engineering safety of nuclear facilities and environmental safety has been advanced. The activities in respective research fields are summarized. Also the international cooperation with USA, FRG, China and others were carried out smoothly. (K.I.)

In the immediate aftermath of the Three Mile Island accident, the Nuclear Regulatory Commission-sponsored investigations of the relation between human issues and safety tended to focus on individual and, at most, group level phenomena. This initial bottom up view of organizational safety has continued to be investigated by the Nuclear Regulatory Commission, as evidence by the four previous papers. Recently, however, work has begun which adopts a top down management/organization approach to nuclear power plant safety. This paper reports on the research, to date, on this focus

Japan's post-Fukushima reconstruction: A case study for implementation of sustainable energy technologies

International Nuclear Information System (INIS)

Nesheiwat, Julia; Cross, Jeffrey S.

2013-01-01

Following World War II, Japan miraculously developed into an economic powerhouse and a model of energy efficiency among developed countries. This lasted more than 65 years until the Northeastern Japan earthquake and tsunami induced nuclear crisis of March 2011 brought Japan to an existential crossroads. Instead of implementing its plans to increase nuclear power generation capacity from thirty percent to fifty percent, Japan shut-down all fifty-four nuclear reactors for safety checks and stress-checks (two have since been restarted), resulting in reduced power generation during the summer of 2012. The reconstruction of Northeastern Japan approaches at a time when the world is grappling with a transition to sustainable energy technologies—one that will require substantial investment but one that would result in fundamental changes in infrastructure and energy efficiency. Certain reconstruction methods can be inappropriate in the social, cultural and climatic context of disaster affected areas. Thus, how can practitioners employ sustainable reconstructions which better respond to local housing needs and availability of natural energy resources without a framework in place? This paper aims at sensitizing policy-makers and stakeholders involved in post disaster reconstruction by recognizing advantages of deploying sustainable energy technologies, to reduce dependence of vulnerable communities on external markets. - Highlights: • We examine the energy challenges faced by Japan in the aftermath of Fukushima. • We identify policy measures for the use of energy technologies applicable to disaster prone nations. • We evaluate the potential for renewable energy to support reduced reliance on nuclear energy in Japan. • We model scenarios for eco-towns and smart-cities in post-disaster reconstruction. • We assess the role of culture in formulating energy policy in post-disaster reconstruction

INS/NUPEC presents one of Public acceptance (PA) methods for nuclear power in Japan, 'PA activity by using Nuclear Power Plant Safety Demonstration and Analysis', by using one of videos which is explained and analyzed accident events (Loss of Coolant Accident). Safety regulations of The National Government are strictly implemented in licensing at each of basic design and detailed design. To support safety regulation activities conducted by the National Government, INS/NLTPEC continuously implement Safety demonstration and analysis. With safety demonstration and analysis, made by assuming some abnormal conditions, what impacts could be produced by the assumed conditions are forecast based on specific design data on a given nuclear power plants. When analysis results compared with relevant decision criteria, the safety of nuclear power plants is confirmed. The decision criteria are designed to help judge if or not safety design of nuclear power plants is properly made. The decision criteria are set in the safety examination guidelines by taking sufficient safety allowance based on the latest technical knowledge obtained from a wide range of tests and safety studies. Safety demonstration and analysis is made by taking the procedure which are summarized in this presentation. In Japan, various PA (Public Acceptance) pamphlets and videos on nuclear energy have been published. But many of them focused on such topics as necessity or importance of nuclear energy, basic principles of nuclear power generation, etc., and a few described safety evaluation particularly of abnormal and accident events in accordance with the regulatory requirements. In this background, INS/NUPEC has been making efforts to prepare PA pamphlets and videos to explain the safety of nuclear power plants, to be simple and concrete enough, using various analytical computations for abnormal and accident events. In results, PA activity of INS/NUPEC is evaluated highly by the people

Kawata, Norio

2015-01-01

Since the terrorist attacks on the U.S. on September 11th, 2001, Nuclear Security has been focused on and treated as a global issue in the international community and it has also been discussed as a real and serious threat to nuclear power plants in the world since 'The Great East Japan Earthquake' in March, 2011. The International Atomic Energy Agency (IAEA) issued a document including Nuclear Security Recommendations (INFCIRC/225/Rev.5) (NSS 13) in the Nuclear Security Series and emphasized the necessity of fostering Nuclear Security Culture. Nuclear Security Culture has been frequently discussed at various kinds of seminars and events. Since the officials in charge of Nuclear Security are familiar with the area of Nuclear Safety, the relationships between Nuclear Safety Culture and Nuclear Security Culture have been the point in controversy. This paper clarifies relevance between Nuclear Safety and Security, considers resemblances and differences of their concepts and lessons learned for each culture from nuclear power plant accidents, and promotes deeper understanding of Nuclear Safety and Nuclear Security Culture.

On September 30, 1999, a criticality accident occurred at the uranium processing facility of the JCO Co. Ltd. (hereinafter referred to as ''JCO'') Tokai plant, located in Tokaimura, Ibaraki Prefecture. This was an unprecedented accident in Japan's history of peaceful use of nuclear power, resulting in three workers exposed to severe radiation, two of whom died, and the evacuation and enforced indoor confinement of local residents. Nuclear power suppliers must take personal responsibility for ensuring safety. In this connection, the electric power industry, heavy electric machinery manufacturers, fuel fabricators, and nuclear power research organizations gathered together to establish the Nuclear Safety Network (NSnet) in December 1999, based on the resolve to share and improve the level of the safety culture across the entire nuclear power industry and to assure that such an accident never occurs again. NSnet serves as a link between nuclear power enterprises, research organizations, and other bodies, based on the principles of equality and reciprocity. A variety of activities are pursued, such as diffusing a safety culture, implementing mutual evaluation among members, and exchanging safety-related information. Aiming to share and improve the safety culture throughout the entire nuclear power industry, NSnet thoroughly implements the principle of safety first, while at the same time making efforts to restore trust in nuclear power

Experience with nuclear safety standards development in non-governmental international organizations

Becker, K.

1985-01-01

Besides the IAEA as a 'governmental' organization dealing with basic safety recommendations addressed primarily to the national regulatory bodies in developing countries, two closely related non-governmental international standards organizations have gained extensive experience in the field of nuclear standardization. Over more than 25 years since their formation, both (a) the International Organization for Standardization's (ISO) Technical Committee 85 'Nuclear Energy', in particular in its Sub-Committee 3 'Reactor Technology and Safety' and (b) the International Electrotechnical Commission's (IEC) Technical Committee 45 'Nuclear Instrumentation' have published numerous standards. A brief review is given of these, draft standards, and other documents planned to become international standards. Many of them deal with rather specialized topics typical for 'industrial' standards such as standardized procedures, instruments, methods, materials, test methods, terminology, and signs and symbols, but others are directly related to more basic safety issues. In some areas such as quality assurance, seismic aspects of siting and terminology, there has been in the past occasional overlap in the activities of the NUSS programme, IEC and ISO. Letters of Understanding have since 1981 contributed to clarifying the borderlines and to avoiding redundant efforts. Also, some experiences and problems are described arising, for example, from the harmonization of different national safety philosophies and traditions into universally accepted international standards, and the transfer of international standards into national standards systems. Finally, based on a recent comprehensive compilation of some 3300 nuclear standards and standards projects, an attempt is made to present a cost/benefit analysis and an outlook on future developments.

The nuclear safety regulations in Japan place a basis on the deterministic approach with the defence-in-depth philosophy and engineering judgments. However, as the development of PSA (Probabilistic Safety Assessment) technologies in recent years, the Nuclear Safety Commission (NSC) began to consider that the utilization of risk information in addition to the traditional deterministic approach could be very effective for the safety regulations to improve rationality, consistency, transparency and efficiency by appropriate allocation of limited resources for the regulatory activities. In order to show the basic strategy, the NSC published the policy for introduction of Risk-Informed Regulation (RIR) in November 2003. The safety goals that play an important role in RIR were tentatively established in December 2003 while the performance goals are under development as of May, 2005. It is expected that RIR be gradually introduced from the applicable area. The NSC is now examining what the RIR system in Japan should be by making each role and incentive of the competent organizations clear. In the future, when the experiences on application of the safety goals are accumulated, RIR will be consistently applied from design to operational area. This paper describes the recent activities of the NSC for introduction of RIR in Japan and development of the safety goals including the performance goals. (authors)

A Japan's challenge - towards creating a most robust nuclear energy future

Suzuki, A. [Japan Atomic Energy Agency, Ibaraki (Japan)

2014-07-01

'Full text:' The Fukushima Daiichi accident raises a fundamental question: Can science and technology prevent the inevitability of serious accidents, especially those with low probabilities and high consequences? This question reminds us of a longstanding issue with the trans-sciences, originally addressed by a great physicist, Alvin Weinberg, well before the Three Mile Island and Chernobyl accidents. A most robust nuclear energy future would not come to pass without answering it. With the human-behavior-linked nature of the Fukushima Daiichi accident in mind, an innovative way to assure the safety is to be developed not merely from the standpoint of technical measures but rather from a view of point of inter-related institutional structure between the technology and the social system. In other words, social and institutional arrangements to strengthen self-efforts for continuous improvement of safety are to be made specifically dedicated to pursuing procedural rationality between the inner and outer environments, in which a communicative action with transparency and a self-regulating system are especially useful. This is the challenge facing the global nuclear future as well as Japan to be tackled in the wake of the accident. (author)

Regulatory requirements for nuclear power plants (NPPs) have been reviewed and restructured in Japan, in order to accommodate recent technical progress in a timely manner. In this new regulatory process, the governmental technical requirements are modified to performance specifications and the consensus codes and standards established by academic and public societies are being used as prescriptive specifications to realize the performance. As a first step, a fitness-rule to evaluate structural integrity of the components having cracks was introduced into the Japanese regulatory rules in Oct. 2003. 'Rules on Fitness-for-Service for Nuclear Power Plants' by the Japan Society of Mechanical Engineers (JSME) was utilized as a prescriptive specification for in-service-inspections and for the integrity evaluation of the components with stress corrosion cracks and fatigue cracks. The process is being extended to other requirements for structural design and construction of mechanical components and concrete containments, as well as requirements for welding. Prescriptive specifications for the requirements by the JSME and other consensus codes have been technically reviewed by a regulatory body, the Nuclear and Industrial Safety Agency, and specified as regulatory standards for the licensing procedure. In the course of the review, consistency and coverage of the requirements were examined against the Safety Design Guidelines by the Nuclear Safety Commission and the safety requirements for design of nuclear power plant by the International Atomic Energy Agency, NS-R-1. Additional requirements against the stress corrosion cracking, hydrogen accumulation, high-cycle thermal fatigue, etc. are being specified in the requirements to prevent troubles experienced in NPPs in Japan and overseas. This paper describes outlines of the on-going activities restructuring the technical standards for regulation of NPPs in Japan. (authors)

The Fukushima disaster was a wake-up call for the nuclear industry as well as a shocking revelation of the inner workings of the Japanese power sector. The political fallout from the event was far-reaching, pushing governments into abandoning nuclear expansion, turning instead to fossil fuels and renewable energy alternatives. While the move away from nuclear energy was deemed a move critical to political survival in Europe, we find that political candidates running on anti-nuclear platforms did not win elections, while the pro-nuclear Liberal Democratic Party won government in the 2012 elections. Against this backdrop, we analyse the energy conflict in Japan using a framework of values versus interests and consider the regulatory and cultural conditions that contributed to the disaster. A number of considerations lie in the way of an organised phase-out of nuclear power in Japan. We also consider the possible policy paths Japan may take. - Highlights: • As Europeans urgently phase-out nuclear power, Japan voted out such a government despite high anti-nuclear sentiment. • Regulatory climate within the nuclear industry was dysfunctional as a result of being captured by the ‘nuclear village’. • New ‘independent’ nuclear authority is made up of previously captured agency. • With a pro-nuclear government, and lack of really independent nuclear authority, old problems may yet arise. • Japanese government has to choose between lowering emissions, low popular support for nuclear power, and affordable electricity

Full text: Nuclear power accounts for about 35% electric power generation in Japan, playing an important role of energy supply. In addition, a commercial scale reprocessing plant is under construction. A real nuclear fuel cycle is imminently close at hand in Japan. COP3 in Kyoto in 1997 called for every country's fight against global warming. Nuclear power in Japan is expected to take another important role from this viewpoint, too. In order to play these expected roles, it is absolutely needed to preserve nuclear talented experts, by maintaining, succeeding and newly developing nuclear technologies. The Atomic Energy Commission of Japan also points out in its report on 'Long-Term Program for Research, Development and Utilization of Nuclear Energy' that research-and development activities are very important to motivate young researchers and engineers who might choose to take nuclear careers. However, young generation capable students seem to avoid majoring nuclear engineering in view of nuclear industry uncertainties in future caused by stagnated Japanese economy since 1990, liberalization of electricity markets, future electricity demand modest forecasts, matured light water reactor technologies, and repeated nuclear accidents inside and outside the country, etc. Aging research facilities at universities are another de-motivating element of causing the reduction of qualifiable students. Consequently, preservation of knowledge and expertise is becoming a big concern for future. According to the survey conducted by the Japan Atomic Industrial Forum (JAIF) over two years since 2002, participated by the members from nuclear industries, universities, research organizations, electricity industries, nuclear plant suppliers and construction contractors, as well as the questionnaire sent to students, there are various issues for preservation of nuclear talented experts in Japan. Although the number of graduates on nuclear engineering is actually about 350 every year, and

This paper reports that since the Chernobyl nuclear plant accident in 1986, over 70 of the International Atomic Energy Agency's 112 member states have adopted two conventions to enhance international cooperation by providing timely notification of an accident and emergency assistance. The Agency and other international organizations also developed programs to improve nuclear power plant safety and minimize dangers from radioactive contamination. Despite meaningful improvements, some of the measures have limitations, and serious nuclear safety problems remain in the design and operation of the older, Soviet-designed nuclear power plants. The Agency's ability to select reactors under its operational safety review program is limited. Also, information on the extent and seriousness of safety-related incidents at reactors in foreign countries is not publicly available. No agreements exist among nuclear power countries to make compliance with an nuclear safety standards or principles mandatory. Currently, adherence to international safety standards or principles is voluntary and nonbinding. Some states support the concept of mandatory compliance, but others, including the United States, believe that mandatory compliance infringes on national sovereignty and that the responsibility for nuclear reactor safety remains with each nation

Safety study of fire protection for nuclear fuel cycle facility

International Nuclear Information System (INIS)

2013-01-01

Insufficiencies in the fire protection system of the nuclear reactor facilities were pointed out when the fire occurred due to the Niigata prefecture-Chuetsu-oki Earthquake in July, 2007. This prompted the revision of the fire protection safety examination guideline for nuclear reactors as well as commercial guidelines. The commercial guidelines have been endorsed by the regulatory body. Now commercial fire protection standards for nuclear facilities such as the design guideline and the management guideline for protecting fire in the Light Water Reactors (LWRs) are available, however, those to apply to the nuclear fuel cycle facilities such as mixed oxide fuel fabrication facility (MFFF) have not been established. For the improvement of fire protection system of the nuclear fuel cycle facilities, the development of a standard for the fire protection, corresponding to the commercial standard for LWRs were required. Thus, Japan Nuclear Energy Safety Organization (JNES) formulated a fire protection guidelines for nuclear fuel cycle facilities as a standard relevant to the fire protection of the nuclear fuel cycle facilities considering functions specific to the nuclear fuel cycle facilities. In formulating the guidelines, investigation has been conduced on the commercial guidelines for nuclear reactors in Japan and the standards relevant to the fire protection of nuclear facilities in USA and other countries as well as non-nuclear industrial fire protection standards. The guideline consists of two parts; Equipments and Management, as the commercial guidances of the nuclear reactor. In addition, the acquisition of fire evaluation data for a components (an electric cabinet, cable, oil etc.) targeted for spread of fire and the evaluation model of fire source were continued for the fire hazard analysis (FHA).

Japan finances research programs on photovoltaic conversion since 1974. Research in this domain is one of the 11 priorities of NEDO, the agency of means of the ministry of economy, trade and industry of Japan. The search for an abatement of production costs and of an increase of cells efficiency is mentioned in NEDO's programs as soon as the beginning of the 1990's. A road map has been defined which foresees photovoltaic energy production costs equivalent to the ones of thermal conversion by 2030, i.e. 7 yen/kWh (4.4 cents of euro/kWh). The use of new materials in dye-sensitized solar cells (DSSC) or organic solar cells, and of new structures (multi-junctions) is explored to reach this objective. The organic photovoltaic technology is more particularly considered for small generation units in mobile or domestic technologies. Japan is particularly in advance in the improvement of DSSC cells efficiency, in particular in the domain of the research on solid electrolytes. Europe seems more in advance in the domain of the new generation of organic solar cells. Therefore, a complementarity may be found between Japan and French teams in the domain of organic solar cells improvement through collaboration programs. (J.S.)

New safety concept for geological disposal in Japan - -16339

International Nuclear Information System (INIS)

Kitayama, Kazumi

2009-01-01

This paper describes a new safety concept for the Japanese geological disposal program, which is a development of the conventional multi-barrier system concept. The Japanese government established the 'Nuclear Waste Management Organization of Japan' (NUMO) as an implementation body in 2000 based on the 'Final disposal act' following the publication of the 'H-12 Report', which confirmed the scientific and engineering feasibility of HLW geological disposal in Japan. Since then, NUMO has undertaken further technical developments aimed at achieving safe and efficient implementation of final disposal. The safety concept developed in the 'H-12 Report' provides sufficient safety on the basis of site-generic considerations. However, it is considered to be over-conservative and therefore does not represent the most probable performance of the engineered or natural barriers. Recently, concrete measures have been proposed requiring the safety case to be presented in terms of a realistic assessment of the most probable performance. This approach takes into account the safety functions of both engineered and natural barriers as well as the long-term static geochemical equilibrium. In particular, the evolution of the safety performance of engineered and natural barriers can be efficiently augmented by the realistic long-term geochemical equilibrium. (author)

The contributions of this publication first address the Japanese local context (organization, mentality, cultural background, thinking and action modes), and secondly the environmental and radiological impact of the Fukushima accident, notably in comparison with Chernobyl (contamination is much more localized, sometimes higher; a larger concerned population but quicker and more efficient protection measures; more severe consequences due to population displacement). The third article discusses the international impact of the accident: known or foreseen consequences on nuclear programs, discussion on safety strengthening and on governance, evolution of public opinion, possible consequences on climate negotiations. The last article proposes an overview of the current situation of Japan which must mobilize all the available energy resources to face the difficulties in electricity supply

An analysis was made on the potential and cost of reducing carbon dioxide (CO 2 ) emissions from Japan's long-term energy systems by using the MARKAL model, developed in the Energy Technology Systems Analysis Programme (ETSAP) of International Energy Agency (IEA). Assuming future growths of GDP, the demand for energy services was estimated for the analytical time horizon 1990-2050. Assumptions were made also on prices and availability of fossil fuels, and on availability of nuclear and renewable energy. CO 2 emissions and system costs were compared between energy demand and supply scenarios defined with different assumptions on nuclear energy, a CO 2 disposal option, and natural gas imports. Main results were as follows. Without nuclear energy, the CO 2 emissions will hardly be reduced because of the increases of coal utilization. CO 2 disposal will be effective in reducing the emissions, however at much higher costs than the case with nuclear energy. The expansion of natural gas imports alone will not reduce the emissions at enough low levels. (author)

The historical perspectives of the international organizations' role concerning the development and spreading of the peaceful uses of nuclear energy, taking into account the national interests within and towards these organizations, are portrayed. The difference in political status between the so-called nuclear and non-nuclear States, lodged in Articles I and II of the Non-Proliferation Treaty is an important factor. The effects so far of these differences in status on the interest of nuclear States to participate in organizations and on factors which might possibly lead to conflict between these two groups are presented. The author skirts the cooperation between organizations (international bureaucracies, group-formation of states). (HP/LN) [de

Since starting the research and development program for peaceful use of nuclear energy in 1950's, various research and demonstration facilities have been constructed in research organizations, universities and commercial sectors in Japan. Some of the nuclear facilities constructed in the early stage of research and development have been retired to be decommissioned because of completion of the initial objectives in the Japan Atomic Energy Research Institute (JAERI). On the other hand, since the first commercial operation of nuclear power plant (1968), the number of nuclear power plants has increased up to 52 plants operating as of August 2003 in Japan. The shear of nuclear energy accounts approximately for 35% of electricity generation in total at present time. However, several nuclear power plants have been operated for more than 25 years and two nuclear power plants are expected to be finally shutdown by 2010 to be eventually decommissioned. The Tokai Power Station, the oldest Japanese nuclear power plant operated by the Japan Atomic Power Company, was permanently shutdown from March 1998 and it is in decommissioning stage at this time. The Fugen, which is advanced thermal reactor operated by the Japan Nuclear Cycle Development Institute (JNC), was finally shutdown on March, 2003 after 25 years operation to be decommissioned. In addition, relating to planned unification between JAERI and JNC in 2005, the studies have been in progress on decommissioning and radioactive waste treatment and disposal; the cost was estimated to be 10 to 30 billion Japanese yens per year during 80 years for decommissioning of nearly 200 nuclear facilities. Decommissioning of nuclear facilities is thus getting to be one of important issues in Japan. Decommissioning of nuclear facilities might be possible using conventional and/or partially improved technology. However, reviewing project feedback experience on decommissioning and decontamination might contribute to solve various issues

Since the beginning of the 21st century, educating the next generation of nuclear engineers has been of interest to groups who are concerned with the recent decline in the number of nuclear engineers in universities and industries. Discussions and proposals have been summarized in independent reports by industry (JAIF; Japan Atomic Industrial Forum), government (Science Council of Japan) and the academe (AESJ; Atomic Energy Society of Japan). In June 2005 a Committee on Education (CE) was established within AESJ with the intention of coordinating the groups interested in nuclear education in Japan. The birth of CE was timely, because the importance of nuclear education was emphasized in 'Framework for Nuclear Energy Policy (Oct., 2005)' which was adopted by the Atomic Energy Commission. The Nuclear Energy Subcommittee of the METI (Ministry of Economy, Trade and Industry) Advisory Committee deliberated concrete actions for achieving the basic goals of the Framework for Nuclear Energy Policy and their recommendations were drawn up as a 'Nuclear Energy National Plan'. This was the MEXT (Ministry of Education, Culture, Sports, Science and Technology) and METI action plan to create nuclear energy training programs for universities, etc. A task group, consisting of members from industry, government and academe was organized within JAIF to give advice to these training programs. The author of this paper (and chairman of CE) participated in and made proposals to the task group as a representative of the academe. In this paper, the proposal made by CE and the outline of the final program will be reported. Furthermore, the importance of the partnership between industry, government and academe will be emphasized. (author)

Analysis on Japan's long-term energy outlook considering massive deployment of variable renewable energy under nuclear energy scenario

This paper investigates Japan's long-term energy outlook to 2050 considering massive deployment of solar photovoltaic (PV) system and wind power generation under nuclear energy scenario. The extensive introduction of PV system and wind power system are expected to play an important role in enhancing electricity supply security after Fukushima Nuclear Power Accident which has increased the uncertainty of future additional construction of nuclear power plant in Japan. On these backgrounds, we develop integrated energy assessment model comprised of both econometric energy demand and supply model and optimal power generation mix model. The latter model is able to explicitly analyze the impact of output fluctuation in variable renewable in detailed time resolution at 10 minutes on consecutive 365 days, incorporating the role of stationary battery technology. Simulation results reveal that intermittent fluctuation derived from high penetration level of those renewables is controlled by quick load following operation by natural gas combined cycle power plant, pumped-storage hydro power, stationary battery technology and the output suppression of PV and wind power. The results show as well that massive penetration of the renewables does not necessarily require the comparable scale of stationary battery capacity. Additionally, on the scenario which assumes the decommissioning of nuclear power plants which lifetime are over 40 years, required PV capacity in 2050 amounts to more than double of PV installment potential in both building and abandoned farmland area.

Safety aspects and operating experience of LWR plants in Japan

International Nuclear Information System (INIS)

Aoki, S.; Hinoki, M.

1977-01-01

From the outset of nuclear power development in Japan, major emphasis has been placed on the safety of the nuclear power plants. There are now twelve nuclear power plants in operation with a total output of 6600 MWe. Their operating records were generally satisfactory, but in the 1974 to 1975 period, they experienced somewhat declined availability due to the repair work under the specific circumstances. After investigation of causes of troubles and the countermeasures thereof were made to ensure safety, they are now keeping good performance. In Japan, nuclear power plants are strictly subject to sufficient and careful inspection in compliance with the safety regulation, and are placed under stringent radiation control of employees. Under the various circumstances, however, the period of annual inspection tends to be prolonged more than originally planned, and this consequently is considered to be one of the causes of reduced availability. In order to develop nuclear power generation for the future, it is necessary to put further emphasis on the assurance of safety and to endeavor to devise measures to improve availability of the plants, based on the careful analysis of causes which reduce plant availability. This paper discusses the results of studies made for the following items from such viewpoints: (1) Safety and Operating Experience of LWR Nuclear Power Plants in Japan; a) Operating experience with light water reactors b) Improvements in design of light water reactors during the past ten years c) Analysis of the factors which affect plant availability; 2) Assurance of Safety and Measures to Increase Availability a) Measures for safety and environmental protection b) Measures to reduce radiation exposure of employees c) Appropriateness of maintenance and inspection work d) Measures to increase plant availability e) Measures to improve reliability of equipments and components; and 3) Future Technical Problems

The International Workshop on Lessons Learned from Strong Earthquake was held at Kashiwazaki civic plaza, Kashiwazaki, Niigata-prefecture, Japan, for three days in June 2008. Kashiwazaki-Kariwa NPP (KK-NPP) is located in the city of Kashiwazaki and the village of Kariwa, and owned and operated by Tokyo Electric Power Company Ltd. (TEPCO). After it experienced the Niigata-ken Chuetsu-oki earthquake in July 2007, IAEA dispatched experts' missions twice and held technical discussions with TEPCO. Through such activities, the IAEA secretariat and experts obtained up-dated information of plant integrity, geological and seismological evaluation and developments of the consultation in the regulatory framework of Japan. Some of the information has been shared with the member states through the reports on findings and lessons learned from the missions to Japan. The international workshop was held to discuss and share the information of lessons learned from strong earthquakes in member states' nuclear installations. It provided the opportunity for participants from abroad to share the information of the recent earthquake and experience in Japan and to visit KK-NPP. And for experts in Japan, the workshop provided the opportunity to share the international approach on seismic-safety-related measures and experiences. The workshop was organised by the IAEA as a part of an extra budgetary project, in cooperation with OECD/NEA, hosted by Japanese organisations including Nuclear and Industrial Safety Agency (NISA), Nuclear Safety Commission (NSC), and Japan Nuclear Energy Safety Organization (JNES). The number of the workshop participants was 70 experts from outside Japan, 27 countries and 2 international organisations, 154 Japanese experts and 81 audience and media personnel, totalling to 305 participants. The three-day workshop was open to the media including the site visit, and covered by NHK (the nation's public broadcasting corporation) and nation-wide and local television

In the wake of the Chernobyl accident in April 1986 and the nuclear near disaster at Three Mile Island in 1979, public concern about the safety of nuclear power has increased. Some of the opponents of nuclear power see it as a unique and ominous danger. Some critics see opposition to it as a moral crusade associated with the struggle for nuclear disarmament. Some describe nuclear power or almost any tampering with radioactivity as evil. Others see it as simply a potentially dangerous technology that is insufficiently understood but argue that it is being developed without adequate protection for public safety. Recently some supporters of nuclear power have argued that it is the answer to the ' greenhouse effect' as it does not produce the gases responsible for global warming. On the other side opponents have argued that the full social and economic costs are never properly considered when assessments are made of the viability or desirability of nuclear power. Meanwhile, many of the workers who have given their skills and working lives to develop nuclear power, or support its development, continue to see it as a great hope for the future, safer and environmentally cleaner than most other energy sources. Many of them find it puzzling and frustrating that others are so hostile, and are angry that the evidence about nuclear energy, as they see it, is woefully misrepresented. At times, this clash of perspectives has completely obscured the possibility of rational debate. At the extremes, some people have argued that there is no alternative to reliance on nuclear power while others have alleged that nuclear power only exists as a cover for nuclear bomb-making, that all radiation is deadly and evil and that people who support nuclear power are concealing this.

A brief description of the main safety aspects of the French nuclear energy programme and of the general safety organization is followed by a discussion on the current thinking in CEA on some important safety issues. As far as methodology is concerned, the use of probabilistic analysis in the licensing procedure is being extensively developed. Reactor safety research is aimed at a better knowledge of the safety margins involved in the present designs of both PWRs and LMFBRs. A greater emphasis should be put during the next years in the safety of the nuclear fuel cycle installations, including waste disposals. Finally, it is suggested that further international cooperation in the field of nuclear safety should be developed in order to insure for all countries the very high safety level which has been achieved up till now.

Safety assessment and verification for nuclear power plants. Safety guide

International Nuclear Information System (INIS)

2004-01-01

This Safety Guide was prepared under the IAEA programme for safety standards for nuclear power plants. The present publication is a revision of the IAEA Safety Guide on Management of Nuclear Power Plants for Safe Operation issued in 1984. It supplements Section 2 of the Safety Requirements publication on Safety of Nuclear Power Plants: Operation. Nuclear power technology is different from the customary technology of power generation from fossil fuel and by hydroelectric means. One major difference between the management of nuclear power plants and that of conventional generating plants is the emphasis that should be placed on nuclear safety, quality assurance, the management of radioactive waste and radiological protection, and the accompanying national regulatory requirements. This Safety Guide highlights the important elements of effective management in relation to these aspects of safety. The attention to be paid to safety requires that the management recognize that personnel involved in the nuclear power programme should understand, respond effectively to, and continuously search for ways to enhance safety in the light of any additional requirements socially and legally demanded of nuclear energy. This will help to ensure that safety policies that result in the safe operation of nuclear power plants are implemented and that margins of safety are always maintained. The structure of the organization, management standards and administrative controls should be such that there is a high degree of assurance that safety policies and decisions are implemented, safety is continuously enhanced and a strong safety culture is promoted and supported. The objective of this publication is to guide Member States in setting up an operating organization which facilitates the safe operation of nuclear power plants to a high level internationally. The second objective is to provide guidance on the most important organizational elements in order to contribute to a strong safety

The possibility of terrorist attacks on nuclear material and nuclear facilities has posed a continuing threat since the events of September 11, 2001. The Japanese government has strengthened its physical protection regime, including legislative amendments, due to the necessity of upgrading the degree of protection of nuclear facilities to be equivalent to international levels, in order to cope effectively with the threat of theft of nuclear material and sabotage of nuclear facilities. In relation to these enhancements of the physical protection regime in Japan, the Japan Nuclear Energy Safety Organization (JNES) gives technical support to the regulatory agency, the Nuclear and Industrial Safety Agency (NISA), in the area of physical protection examination and inspection, through the development of technical guides for inspectors and operators, acquisition, analysis, and evaluation of related information, and international cooperation. This support is aimed at ensuring the consistent implementation of physical protection measures in Japan. In the future also, the JNES will provide further support to the NISA aimed at a well-developed physical protection framework in Japan, giving consideration to international physical protection enhancements such as publication of IAEA nuclear security series documents, inter alia Recommendations for physical protection of nuclear material and nuclear facilities being also Revision 5 of INFCIRC 225.

Since June 1997 the standards/specifications and inspection/certification of various products in Japan have been reviewed by Ministries and Agencies, with the aim of reducing direct government intervention to a necessary minimum and creating a free and fair socio-economic system that is fully opened to the international community and based on the rules of self-responsibility and market principles. Reflecting this policy the administrative regulations which prescribe technical standards as specific requirements have been revised by degrees into performance prescriptions. Detailed provisions in ordinances and notices have been abolished gradually to utilize voluntary standards and rules. In the nuclear energy field voluntary standards are being developed to make up statutory performance requirements by the Atomic Energy Society of Japan (AESJ) and the Japan Society of Mechanical Engineers (JSME) together with other organizations such as the Japan Electric Association, the Thermal and Nuclear Power Engineering Society. These voluntary standards and rules by these organizations have been established in order to maintain openness, transparency, fairness, professionalism and promptness and to promote development and globalization

Fukushima Daiichi nuclear power plant accident (Fukushima accident) has brought about a great change in many people's perceptions about nuclear power plant safety. When discussing future energy options for Japan, it is important to have a full grasp of the attitude of a large number of people towards nuclear energy. The Atomic Energy Society of Japan has conducted annual questionnaire survey of 500 adults who live within 30 kilometers of Tokyo Station. The aim of this survey is to assess trends in public attitude towards nuclear energy. The authors that designed the questionnaire entries of this survey have been managing questionnaire data as members of the Data Management Working Group under the Social and Environmental Division of the Atomic Energy Society of Japan. We confirmed the change in public attitude towards nuclear energy through this periodical survey after the Fukushima accident. In particular, public concerns about the use of nuclear energy increased after the Fukushima accident, and many people have raised doubts over the use of nuclear energy in the future. (author)

The development of nuclear merchant ship in Japan was started in 1955 by the establishment of Nuclear Ship Study Group, and since then, the investigation, test and research on nuclear ships have been continued. As a result, a nuclear ocean observation and supply ship was designed for trial. Researches were carried out also in JAERI and Institute for Technical Research of Ships. Meanwhile, the nuclear icebreaker Lenin was completed in Soviet Union in 1959, the nuclear ship Savannah set out for maiden voyage in U.S. in 1962, and the construction of the nuclear ore carrier Otto Hahn was prepared in FRG. Japan Nuclear Ship Development Corp. was established in 1963, and started the design and construction of the first nuclear ship in Japan, Mutsu. The basic policy in the construction is the improvement of nuclear ship technology, the securing of safety, and the use of domestic technologies as far as possible. The progress of the design, construction and test of the Mutsu is described. Owing to the problem of radiation leak, the development of nuclear ships stagnated for a while, but the nuclear plant of the Mutsu demonstrated the expected performance in the functional test, land criticality test and zero output test, and it is expected that the bud of the independent development brought up so far can bear valuable fruit. The independent development of marine nuclear reactors should be continued by selecting the way most suitable to Japan. (Kako, I.)

Japan/India. Towards a nuclear cooperation?

International Nuclear Information System (INIS)

Pajon, Celine

2011-10-01

As diplomatic, economic and strategic relationships between Japan and India have been intensively developed for a decade, the author aims at discussing the very sensitive approach to a nuclear cooperation between these two countries as Japan, while taking benefit of the American nuclear umbrella, is a strong defender of nuclear disarmament and non proliferation, and India has been developing its own civilian and military nuclear programme outside of the international regime which it considers as discriminative. The author first discusses factors which incited Japan to build up a strategic partnership with India in front of the evolution of the political context, of the powerful upswing of China, and of the new American orientation with respect to Delhi. She comments the economic and political stakes of the currently negotiated Japan-India nuclear cooperation agreement which not only concerns the relationships between these both countries, but also French and American industrial groups which are present on the Indian market. She also notices that the Fukushima accident which has put Japan energy choices into question again, is a new deal which is to be taken into account

Since the beginning of the 21st century, educating the next generation nuclear engineers have been an interest to groups, who were concerned of the recent decline in nuclear population in universities and industries. In June 2005, committee on education (CE) was established in AESJ (Atomic Energy Society of Japan), hoping to coordinate the groups related to nuclear education in Japan. The birth of CE was timely; because the importance of nuclear education was emphasized in 'Framework for Nuclear Energy Policy (Oct., 2005)' decided by the Atomic Energy Commission. In this paper, recent activities of CE, especially the proposals CE made related Framework for Nuclear Energy Policy, will be reported. The importance of the partnership with industries, government and academe will be emphasized. (author)

The goal of regulation is to protect public health and safety as well as environment from radiological hazards that may occur as a result of the use of atomic energy. In September 1994, the Korean government issued the Nuclear Safety Policy Statement (NSPS) to establish policy goals of maintaining and achieving high-level of nuclear safety and also help the public understand the national policy and a strong will of the government toward nuclear safety. It declares the importance of establishing safety culture in nuclear community and also specifies five nuclear regulatory principles (Independence, Openness, Clarity, Efficiency and Reliability) and provides the eleven regulatory policy directions. In 2001, the Nuclear Safety Charter was declared to make the highest goal of safety in driving nuclear business clearer; to encourage atomic energy- related institutions and workers to keep in mind the mission and responsibility for assuring safety; to guarantee public confidence in related organizations. The Ministry of Science and Technology (MOST) also issues Yearly Regulatory Policy Directions at the beginning of every year. Recently, the third Atomic Energy Promotion Plan (2007-2011) has been established. It becomes necessary for the relevant organizations to prepare the detailed plans on such areas as nuclear development, safety management, regulation, etc. This paper introduces a multi-level structure of nuclear safety and regulation policy documents in Korea and presents some improvements necessary for better application of the policies

ElBaradei, M.

2006-01-01

The public's perception of risk has a strong influence on a country's energy choices. As with civil aviation, bioengineering, or any other advanced technology, nuclear power does not come with absolute safety guarantees. What is important is that the risks and benefits are clearly understood. All members of the nuclear community - scientists, operators and safety regulators - should make every effort to provide accurate and easily understood information to improve public understanding of the risks and benefits of nuclear energy. Common misconceptions can be of great influence in shaping public acceptance of nuclear power. How a given nation balances the risk of a nuclear accident against other factors - such as air pollution, dammed rivers, mining accidents, or dependency on foreign fuel supplies - is already a matter of complexity and legitimate debate. It is essential that the nuclear community be seen as transparent and open in its activities, to increase understanding and confidence in the safe operations of nuclear facilities

In June 2010, the Japanese cabinet adopted a new Basic Energy Plan (BEP). This was the third such plan that the government has approved since the passage of the Basic Act on Energy Policy in 2002, and it represents the most significant statement of Japanese energy policy in more than four years, since the publication of the New National Energy Strategy (NNES) in 2006. Perhaps more than its predecessors, moreover, the new plan establishes a number of ambitious targets as well as more detailed measures for achieving those targets. Among the targets are a doubling of Japan's 'energy independence ratio,' a doubling of the percentage of electricity generated by renewable sources and nuclear power, and a 30 percent reduction in energy-related CO 2 emissions, all by 2030. This paper explains the origins of the 2010 BEP and why it was adopted. It then describes the content of the plan and how it differs from the NNES. A third section analyzes the appropriateness of the new goals and targets contained in the BEP and their feasibility, finding that achievement of many of the targets was likely to be quite challenging even before the March 2011 earthquake, tsunami, and nuclear crisis. - Highlights: → Origins of Japan's new Basic Energy Plan. → Content of Japan's new Basic Energy Plan. → Feasibility of achieving the targets in Japan's new Basic Energy Plan. → Impact of 2011 earthquake and tsunami on Japanese energy policy.

Severe accidents at nuclear plants can result in long-standing and large-scale disasters encompassing wide areas. The public may have special concerns regarding these plants and radiation-related health risks. It has therefore been argued that risk communications efforts, along with rigid safety management of nuclear plants, are imperative to prevent such accidents, mitigate their impacts, and alleviate public concerns. This article introduces a set of laws, acts, codes, and guidelines concerning nuclear safety in Japan. In addition, the preparedness and mitigation plans and programs for dealing with nuclear accidents and possible disasters are also discussed. Furthermore, the ongoing accidents at the Fukushima nuclear power plants following the Great East Japan Earthquake in 2011, and the government response to them are presented. A set of points regarding the management and communications of power plant accidents are discussed. (author)

One Year After Fukushima, Nuclear Safety Is Stronger

International Nuclear Information System (INIS)

2012-01-01

Full text: Nuclear power is safer than it was a year ago as the nuclear industry, regulators and governments act on the lessons of Fukushima, but that safety must never be taken for granted, said Yukiya Amano, Director General of the International Atomic Energy Agency (IAEA). Speaking ahead of the first anniversary of the Fukushima Daiichi nuclear accident on 11 March, Amano said a culture of constant vigilance and improvement was vital to ensure that the benefits of nuclear power could be harnessed as safely as humanly possible. 'Nuclear safety is stronger than it was a year ago', he said. 'Fukushima Daiichi was a very serious accident, but we know what went wrong and we have a clear course of action to tackle those causes - not only in Japan, but anywhere in the world. 'Now we have to keep up the momentum. Complacency can kill'. On 11 March 2011 a huge earthquake and tsunami left more than 20 000 people dead or missing in eastern Japan. Amidst widespread destruction, the tsunami slammed into the Fukushima Daiichi Nuclear Power Station, disabling cooling systems and leading to fuel meltdowns in three of the six Units. The accident was a jolt to the nuclear industry, regulators and governments. It was triggered by a massive force of nature, but it was existing weaknesses of design regarding defence against natural hazards, regulatory oversight, accident management and emergency response that allowed it to unfold as it did. For example: The nuclear regulator was not sufficiently independent, allowing weak oversight of the operator, TEPCO, and regulatory requirements fell short of international best practice; Not enough attention was paid to guarding against possible extreme events at the Fukushima Daiichi site, leaving critical safety functions such as cooling systems vulnerable to the tsunami; Training to respond to serious accidents was inadequate, as were mitigation measures to prevent hydrogen explosions and protect the venting system; and Accident command lines

Nuclear fuel cycle in Japan : status and perspective

International Nuclear Information System (INIS)

Suzuki, Atsuyuki

1996-01-01

Nearly one third of electricity in Japan is being generated by nuclear fission primarily by light-water reactors. The industries to supply uranium fuel for these reactors have been well established including the capability for uranium enrichment. From the onset of nuclear program in Japan, a country with thin energy resources, the emphasis has been placed on maximizing the efficiency of uranium utilization. Thus the national nuclear program set forth by the Japan Atomic Energy Commission has consistently called for the establishment of closed fuel cycle, or for recycling of nuclear fuel. As part of such efforts in private sectors, the first commercial reprocessing plant is now under construction at Rokkasho-mura. The program to develop technologies for recycling nuclear fuel in a fast reactor system is also in progress steadily under the governmental support, while the Monju accident casts a long shadow on the future of fast reactor development in Japan. Even though the price of uranium has been stable at relatively low level in recent years, the uranium market in the longer time range is somewhat unpredictable. In Asian countries, a rapid growth of nuclear power production is foreseen in the 21st century. Under such circumstances, the effort to pursue the recycling option in Japan is important not only for its own energy security but also for stabilization of future uranium market in the world. The recycling option can also offer more flexible, easier and safer ways of radioactive waste management. Since the recycling option means utilization of plutonium in an industrial scale, special attention is inevitably required from the viewpoint of nuclear non-proliferation. It is the Japan's national policy to develop recycling technologies in compliance with the NPT and IAEA safeguard system as well as to maintain the transparency of its developmental program.

Ishii, M.

1997-01-01

There is increasing concern in East Asia about regional cooperation in the field of nuclear power. At the APEC conference in Osaka in 1995, APEC (Asia Pacific Economic Cooperation) established an Energy Research Center. The center has started to perform joint research forecasts on energy supply and demand for the region. Japan proposed the inauguration of a Conference on Nuclear Safety in Asia at the Moscow Nuclear Energy Summit in 1996. The first conference was held in Tokyo that year. This year, the conference will be held in Seoul. Japan's Atomic Energy Commission sponsors the International Conference for Nuclear Cooperation in Asia every year. This year marks the eighth conference. The outstanding feature of this year's conference was that so many countries stressed regional cooperation. South Korea proposed the installation of a regional online radiation monitoring system. The Philippines asserted the need for a cooperative mechanism on the lines of ASIATOM. Why is so much concern now being focused on nuclear power cooperation in East Asia? What kind of regional cooperation is necessary, and what kind is possible? What are the unique features of nuclear power cooperation in East Asia? These are the points addressed in this paper. (author)

In this study, we showed an energy demand and supply scenario toward the year 2100 in Japan, which underlies JAEA's 'Nuclear Energy Vision 2100' published in October 2008. This energy demand and supply scenario aimed at the coexistence of the reduction of the carbon dioxide emission and the energy security through reduction of the fossil fuel usage, positive electrification and the nuclear energy usage. We reduced the ratio of the fossil fuel in the primary energy supply to about 1/3 and extend the share of renewable and nuclear energy to 70% from current 15%. As a result, the carbon dioxide emission was reduced to current 10%, and it developed that the half was the contribution of the nuclear energy. (author)

Outlook for world nuclear power generation and long-term energy supply and demand situations

International Nuclear Information System (INIS)

Matsuo, Yuhji

2012-01-01

In this article, the author presents a long-term outlook for the world's nuclear generating capacity, taking into account the nuclear policy changes after Fukushima Daiichi nuclear power plant accident. World primary energy demand will grow from 11.2 billion tons of oil equivalent (toe) in 2009 to 17.3 billion toe in 2035. Along with this rapid increase in global energy consumption, the world's nuclear generating capacity will grow from 392 GW in 2010 to 484 GW in 2020 and 574 GW in 2035 in the 'Reference scenario'. Even in the 'Low nuclear scenario', where the maximum impact of Fukushima accident to the nuclear policies of each government is assumed, it will continue to grow in the future, exceeding 500 GW in 2035. In particular, Asian countries such as China and India will lead the growth both in the energy demand and in the nuclear power capacity. Therefore, it is essential to better ensure the safety of nuclear power generation. It is important for technologically developed countries, including Japan, to make active contributions to the establishment of a global nuclear safety control system. On the other hand, energy security and global warming will continue to be major issues, which will make it indispensable to make the best effort to save energy and expand renewable energy utilization. Japan is competitive in energy-saving and environmental conservation technologies, thus further development and utilization of there technologies should be a key option of Japan's growth growth strategy in the future.

Highlights: • A psychometric model to evaluate ‘safety climate’ at nuclear research facilities. • The model presented evidences of good psychometric qualities. • The model was applied to nuclear research facilities in Brazil. • Some ‘safety culture’ weaknesses were detected in the assessed organization. • A potential tool to develop safety management programs in nuclear facilities. - Abstract: A safe and reliable operation of nuclear power plants depends not only on technical performance, but also on the people and on the organization. Organizational factors have been recognized as the main causal mechanisms of accidents by research organizations through USA, Europe and Japan. Deficiencies related with these factors reveal weaknesses in the organization’s safety culture. A significant number of instruments to assess the safety culture based on psychometric models that evaluate safety climate through questionnaires, and which are based on reliability and validity evidences, have been published in health and ‘safety at work’ areas. However, there are few safety culture assessment instruments with these characteristics (reliability and validity) available on nuclear literature. Therefore, this work proposes an instrument to evaluate, with valid and reliable measures, the safety climate of nuclear research facilities. The instrument was developed based on methodological principles applied to research modeling and its psychometric properties were evaluated by a reliability analysis and validation of content, face and construct. The instrument was applied to an important nuclear research organization in Brazil. This organization comprises 4 research reactors and many nuclear laboratories. The survey results made possible a demographic characterization and the identification of some possible safety culture weaknesses and pointing out potential areas to be improved in the assessed organization.

After the nuclear accidents in Japan, GRS has carried out in-depth investigations of the events. On the one hand, the accident sequences in the affected units have been analysed from various viewpoints. On the other hand, the transferability of the findings to German plants has been examined to possibly make recommendations for safety improvements. The accident sequences at Fukushima Daiichi have been traced with as much detail as possible based on all available information. Additional insights have been drawn from thermohydraulic analyses with the GRS code system ATHLET-CD/COCOSYS focusing on the events in units 2 and 3, e.g. with regard to core damage and the state of the containments in the first days of the accident sequence. In-depth investigations have also been carried out on topics such as natural external hazards, electrical power supply or organizational measures. In addition, methodological studies on further topics related with the accidents have been performed. Through a detailed analysis of the relevant data from the events in Japan, the basis for an in-depth examination of the transferability to German plants was created. It was found that an implementation of most of the insights gained from the investigations had already been initiated as part of the GRS information notice 2012/02. Further findings have been communicated to the federal government and introduced into other relevant bodies, e.g. the Nuclear Safety Standards Committee (KTA) or the Reactor Safety Commission (RSK).

Brookhaven National Laboratory has conducted a study on the need and feasibility of an independent organization to investigate significant safety events for the Office for Analysis and Evaluation of Operational Data, USNRC. The study consists of three parts: the need for an independent organization to investigate significant safety events, alternative organizations to conduct investigations, and legislative requirements. The determination of need was investigated by reviewing current NRC investigation practices, comparing aviation and nuclear industry practices, and interviewing a spectrum of representatives from the nuclear industry, the regulatory agency, and the public sector. The advantages and disadvantages of alternative independent organizations were studied, namely, an Office of Nuclear Safety headed by a director reporting to the Executive Director for Operations (EDO) of NRC; an Office of Nuclear Safety headed by a director reporting to the NRC Commissioners; a multi-member NTSB-type Nuclear Safety Board independent of the NRC. The costs associated with operating a Nuclear Safety Board were also included in the study. The legislative requirements, both new authority and changes to the existing NRC legislative authority, were studied. 134 references

Scherrer, J.; Evrard, J.M.; Ney, J.

1986-01-01

Within the general context of nuclear safety, the Central Nuclear Installation Safety Service of the French Ministry for Industry and its technical backup, the Institute for Radiation Protection and Nuclear Safety of the CEA (Atomic Energy Commission), have established a special organization designed to provide real-time forecasts of the evolution of a nuclear accident situation with sufficient forewarning for the local representative of the Government (the Commissaire de la Republique in the Departement affected) to implement, as required, effective countermeasures to protect the population - for example, confinement indoors or evacuation. Descriptions are given of the principles of this organization and the particular precautions taken to confront the problems of mobilizing experts and of dealing with the saturation of normal telecommunications channels to be expected in the event of a nuclear accident. The organization set up for the installations belonging to Electricite de France is given as a detailed example. Particular stress is placed on the organizational arrangements of the Institute for Radiation Protection and Nuclear Safety designed to provide the emergency teams with the evaluation and forecasting tools they require to carry out their tasks. The procedures are on the whole well developed for atmospheric radioactivity transport, for which operational models already exist. Computer-backed methods with improved performance are at present being developed. A method of forecasting the behaviour of the releases resulting from nuclear accidents is set out for pressurized water reactors, based on evaluating the physical state of the installation, confinement integrity, availability of safety and backup systems, support systems and feed sources and on forecasting how this state will develop on the basis of measured and inferred physical values transmitted from the affected power station through a national network. The experience acquired during accident

Nuclear Energy General Objectives

International Nuclear Information System (INIS)

2011-01-01

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

Organization of nuclear safety and radiation protection in Switzerland

1995-01-01

In Switzerland an important distinction is made between radiation protection (in charge of the use of ionizing radiations for medical uses or non nuclear industry), and nuclear safety (in charge of nuclear industry, including prevention or limitation of any risk of nuclear accident). In the eighties, it has been decided to make two laws for these two topics. The law for radioprotection, voted in 1991 is enforced since 1994 by OFSP (Office Federal de la Sante Publique). It performs any radiation monitoring outside nuclear industry plants. The law for nuclear safety, that should be enforced by OFEN (Office Federal de l'ENergie), is still not voted. The only existing legislation is the 1959 atomic law. (D.L.). 1 fig., 1 map

The Article 8-2 of Atomic Energy Act requires the government to establish Atomic Energy Promotion Plan every five years. It sets out national nuclear energy policies in a systematic and consistent way. The plan presents the goals and basic directions of national nuclear energy policies on the basis of current status and prospects. Both areas of utilization and safety management of nuclear energy are included and various projects and schedules are delineated based on the national policy directions. The safety management area in this plan deals with the overall safety and regulation policy. Its detail projects and schedule should be developed in separate plans by responsible ministries under the mediation of the MOST. As a regulatory authority, MOST is responsible for safety management area and its technical support organization, KINS has developed Comprehensive Nuclear Safety Regulation Plan as an implementation plan of safety area. This paper presents the development process and specific projects contained in the Comprehensive Nuclear Safety Regulation Plan which is under development now

Major nuclear research institutes in Japan are the Japan Atomic Energy Research Institute (JAERI), Nuclear Cycle Development Institute (JNC), National Research Institute of Radiological Science (NIRS), and the Institute of Physical and Chemical Research (RIKEN). In the 50s and 60s JAERI concentrated on the introduction of nuclear technology from overseas. Energy security issues led to the development of a strong nuclear power programme in the next two decades resulting in Japan having 50 light water cooled nuclear power plants in operation. Japan also worked on other reactor concepts. The current emphasis of JAERI is on advanced reactors and nuclear fusion. Its budget of 270 million US$ supports five research establishments. JAERI has strong collaboration with industry and university system on nuclear and other advanced research topics (neutron science, photon science). In many areas Japan has strong international links. JAERI has also been transferring know-how on radioisotope and radiation applications to the developing countries particularly through IAEA-RCA mechanisms. (author)

Annual report of VATESI - Lithuanian Nuclear Safety Authority's activity in 1997 is presented. According to the prescribed responsibilities by the Law on Nuclear Energy and by the statute, VATESI's main fields of activities in 1997 were evaluation of the safety of Ignalina NPP, supervision of Ignalina NPP's operational safety, control of the implementation of safety improvement program SIP-2 in Ignalina NPP, preparation for the licensing of the unit No.1 of Ignalina NPP, accountancy and control of nuclear materials, regulation of radioactive waste management. Detailed description of all these activities is provided in the report. Important role of international assistance and cooperation is emphasized also. Year 1997 was safe for the operation of Ignalina NPP: there were no safety significant events according to the INES scale, only three events received qualification as level 1 events. In 1997 there was completed SAR of Ignalina NPP, its review report RSR and those were presented to the authorities. Taking into account all recommendations of SAR and RSR a new safety improvement program SIP-2 was made and started implemented

Managing for safety and safety culture within the UK nuclear industry. A regulator's perspective

Tyrer, M.J.

2002-01-01

This paper outlines the basis of the legal system for the regulation of health and safety at work within the United Kingdom (UK), and in particular, the regulation of the nuclear industry. The framework, formulated by the regulator, which has been published as a practical guide for directors, managers, health and safety professionals and employee representatives for the successful management of health and safety is explained. This guidance, however, concentrates, to a large extent, on management systems and only addresses in part the types of issues, such as behaviours, values, attitudes and beliefs which contribute to the safety culture of an organization. The regulator of the UK nuclear industry has considered research, and other work, carried out by several organizations in this area, notably the Advisory Committee on the Safety of Nuclear Installations (ACSNI) and the International Atomic Energy Agency (IAEA), and produced its own framework for managing for safety at nuclear installations. As a regulator, the Health and Safety Executive (HSE), and its inspectorate responsible for regulation of the nuclear industry, HM Nuclear Installations Inspectorate (HMNII), are not the appropriate organization to assess the safety culture of an organization, but positively encourage organizations to both carry out this assessment themselves and to monitor their performance. To this end, HSE has developed, and made available, the Health and Safety Climate Tool which is aimed at providing organizations with information which can be used as part of a continuous improvement process.

The US Department of Energy (DOE) implements the US Government's International Nuclear Safety Program to improve the level of safety at Soviet-designed nuclear power plants in Central and Eastern Europe, Russia, and Unkraine. The program is conducted consistent with guidance and policies established by the US Department of State (DOS) and the Agency for International Development and in close collaboration with the Nuclear Regulatory Commission. Some of the program elements were initiated in 1990 under a bilateral agreement with the former Soviet Union; however, most activities began after the Lisbon Nuclear Safety Initiative was announced by the DOS in 1992. Within DOE, the program is managed by the International Division of the Office of Nuclear Energy. The overall objective of the International Nuclear Safety Program is to make comprehensive improvements in the physical conditions of the power plants, plant operations, infrastructures, and safety cultures of countries operating Soviet-designed reactors. This status report summarizes the Internatioal Nuclear Safety Program's activities that have been completed as of September 1994 and discusses those activities currently in progress

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

In this report, the recent topics in the nuclear field, some investigated data on human resources development (HRD) in nuclear field in Japan and the status of HRD and strategy are presented. We have investigated the basic data on HRD in nuclear field in some Asian countries so that the data could be used to develop HRD strategy. The basic data have been investigated for Japan in the following area. (1) Numbers of graduate and undergraduate students and faculty members for each of the nuclear related departments in the universities have been investigated; (2) The information on the academic associations and societies related to nuclear field has been collected; (3) In addition to the basic data directly related to human resources, the data related to the strategy for nuclear utilization such as the data on research reactors, the data on the level of the application of RI and radiation in medicine, agriculture, industry and environment and the future plan to construct NPPs, the number of NPPs being constructed and NPPs under operation have been collected and tabulated for each country. In Japan, many of the experienced nuclear engineers and scientists who have constructed nuclear power plants and developed the application methodology of RI and radiation, are aging and retiring. Also with the decrease in the construction of nuclear power plants and decrease in the nuclear energy research expenditures, it is becoming more difficult to maintain the present level of capability in designing and manufacturing of nuclear facilities. On the other hand, the educational infrastructures in the universities such as nuclear research reactors and the facilities where handling of radioactive materials is permitted, are deteriorating due to the difficulties to meet the more strict regulatory requirements. With the decrease in the popularity of nuclear energy and maturing of nuclear technology it is becoming more difficult to attract sufficient number of promising young individuals

, such as nuclear safety and a sense of confidence, nuclear nonproliferation, and the treatment and disposal of radioactive waste. This paper identifies these issued and proposes a set of measures to cope with them. (1) Safety and a sense of confidence: The importance of conveying easily understood, sufficient and accurate information to the public is emphasized. (2) Nuclear nonproliferation: Nuclear power inevitably has both a light and dark side. Minimizing the negative aspects is a basic idea of nuclear nonproliferation. This paper delves into the role Japan can play in nuclear nonproliferation and proposes Japan must clearly demonstrate to the rest of the world that it is harnessing nuclear energy solely for peaceful proposes. Japan must generally render active cooperation on the international stage and provide support to Russia in its efforts to dismantle nuclear weapons. (3) The treatment and disposal of radioactive waste: The steady progress of research and development on nuclear waste disposal in addition to institutional improvements designed to cope with the waste problem are described. The prospects for promising technologies are also evaluated. These technologies include the separation and conversion of long-lived radionuclides, and their annihilation in a fast breeder reactor. Furthermore, the paper describes the Japanese nuclear waste disposal policy. In general, every nation must dispose of radioactive waste domestically. Finally, the paper confirms the Japanese policy of utilizing nuclear energy solely for peaceful purposes in the 21st century, takes up the nuclear power policies of the United States and European countries, and points out problems that are awaiting a solution.

Beginning in 2007, the Japan Atomic Energy Agency (JAEA) and the International Atomic Energy Agency (IAEA) Department of Safeguards initiated a workshop series focused on advanced safeguards technologies for the future nuclear fuel cycle (NFC). The goals for these workshops were to address safeguards challenges, to share implementation experiences, to discuss fuel cycle plans and promising research and development, and to address other issues associated with safeguarding new fuel cycle facilities. Concurrently, the workshops also served to promote dialog and problem solving, and to foster closer collaborations for facility design and planning. These workshops have sought participation from IAEA Member States' support programmes (MSSP), the nuclear industry, R and D organizations, state systems of accounting and control (SSAC), regulators and inspectorates to ensure that all possible stakeholder views can be shared in an open process. Workshop presentations have covered, inter alia, national fuel cycle programs and plans, research progress in proliferation resistance (PR) and safeguardability, approaches for nuclear measurement accountancy of large material throughputs and difficult to access material, new and novel radiation detectors with increased sensitivity and automation, and lessons learned from recent development and operation of safeguards systems for complex facilities and the experiences of integrated safeguards (IS) in Japan. Although the title of the workshops presumes an emphasis on technology, participants recognized that early planning and organization, coupled with close cooperation among stakeholders, that is, through the application of 'Safeguards by Design' (SBD) processes that include nuclear safety and security coordination, 'Remote Inspections' and 'Joint-Use of Equipment (JUE)' would be required to enable more successful implementations of safeguards at future NFC facilities.

The mass media has the potential to effect the utilization of nuclear power in Japan. In most cases journalists contact PR staff of the nuclear energy industry (hereinafter called 'the industry') to collect information about various events of nuclear energy. The industry is always ready to distribute related information and hold a press conference timely when necessary. In terms of the organizational structure for the PR activities each electric power company organizes the PR section in-house. The PR staff provides journalists with information on a daily basis. For the purpose of grasping the mass media's awareness, the author conducted interviews with 22 journalists who had experience in reporting news on nuclear energy subjects. The result showed that the journalists recognized the necessity of nuclear energy. The interviewees suggested that a proper press launch should be needed at just the right time especially in emergency situations and a press release should be more easily understandable. This interview showed that journalists considered the media reports as reflection of citizens' opinion. Most of the journalists realize that the influence of the media coverage should not be negligible and they acknowledge commutation between the two sides is gradually improved compared to before.

In the aftermath of the Fukushima nuclear accident, safety measures against hydrogen in severe accident has been recognized as a serious technical problem in Japan. Therefore, efforts have begun to form a common knowledge base between nuclear engineers and experts on combustion and explosion, and to secure and improve future nuclear energy safety. As one of such activities, we have prepared the 'Handbook of Advanced Nuclear Hydrogen Safety'. A handbook committee consisting of Japanese experts in the fields of nuclear and combustion-explosion in universities, nuclear companies, electric companies and research institutes was established in 2012. The objective and consents of the handbook were determined, and the outline of the contents was decided. The concepts of the handbook are as follows: to show advanced nuclear hydrogen safety technologies that nuclear engineers should understand, to show hydrogen safety points to make combustion-explosion experts cooperate with nuclear engineers, to expand information on water radiolysis considering the situation from just after the Fukushima accidents and to the waste management necessary for decommissioning after the accident etc. Many experts have participated to manuscript preparation, which was the first step of forming a hydrogen community across the boundaries of fields. The hydrogen community is expected to grow along with its improvement to the knowledge base on nuclear hydrogen safety. (author)
