[en] The situation of nuclear power development in Japan is severe and unsettled, while its need is absolutely definite. The Basic Policy Subcommittee has studied on future nuclear power development on the basis of adopted measures and governmental examinations as follows: situation in Japan, the need for nuclear power development and its basic policy, and practical measures such as safety, plant location, fuel cycle, advanced reactors and nuclear nonproliferation.

[en] To the decisions concerning the power resource development plans in fiscal 1978 decided in the 75th meeting, revision was made in the 76th meeting of the Council on Power Resource Development and Adjustment. In the original plans; during 8 years from fiscal 1978, the power plants of a total of 71,100 MW will be completed; and for fiscal 1978, 41,250 MW is developed consecutively, while and 3,150 MW is developed newly. 6 hydraulic stations, 18 thermal stations and 2 nuclear stations of 1,990 MW are planned. According to revision, 2,800 MW developed newly at 1 hydraulic, 2 thermal and/nuclear sites was newly incorporated in the plan. As for nuclear power generation, in The Chubu Electric Power Co., Ltd., Unit 3 of BWR type with 1,100 MW is added to the Hamaoka Nuclear Power Station. (Mori, K.)

[en] It is difficult for new sciences and big technologies such as life sciences, nuclear energy, biotechnology, etc. to achieve the appropriate public understanding. One of the issues is the lack of scientific literacy in the public. We propose a new type of nuclear reactor to prepare the opportunity for the public to be acquainted with the information and technology of the nuclear science and engineering. This reactor for interpretation is a symbolic facility adjacent to the scientific and technological museum. Features of the interpretative reactor must be safety and openness. The safety is satisfied by the excess reactivity less than 0.5% Δk/k and little burn up based on the thermal output less than 1 W. (author)

[en] The trends of nuclear power generation in the world as revealed in the survey by Japan Atomic Industrial Forum, Inc. as of December 31, 1984 are described: the present state and the growth outlook. As of December 31, 1984, total of 324 nuclear power plants with aggregate capacity 223,610 MW are in operation in the world. In the one year of 1984, 27 nuclear power plants of total capacity 25,840 MW went into operation. Total of 647 nuclear power plants of 542,530 MW are in operation, are being planned, etc. Nuclear power generation in the top three, i.e. U.S., France and U.S.S.R., in the year 1984 is reviewed. A realistic outlook of the nuclear power to enter into operation in 1990 in the world is forecast as 390,000 MW in the future outlook. (Mori, K.)

[en] The exhibition hall of nuclear power station contributes to understand the visitors about organizations or safety systems through displays and explanations without difficulty. In addition to that, there will be some effect that they give informations to other people after the inspection, so the exhibition hall of nuclear power station plays a vital role of public information considering tens of thousands of yearly visitors. According to that, we made inquiries to the visitors and tried to search what it should be, intending to investigate their actual situation of attitudes or needs, and to accurate effectivities of the present displays in the center of explanations about the organization of nuclear power plant. As a result, the opinion that 'I want to know the organization of nuclear power plant' accounts over 60%, differing from other data of research. And also the opinion after the inspection that 'I am satisfied with acquiring knowledge about the organization' accounts nearly 60%, much higher compared with other choices. In view of these facts, the efficiency of the exhibition hall was certified. The visitor's attitudes of nuclear power is more affirmative than public's one. Even though considering the differences of the survey method, there must be a difference from the first. Besides that, we gained a discernment that educational functions is important through researches for other company. (author)

[en] The R and D activities on energy technologies at the Electrotechnical Laboratory (ETL) are described from a historical viewpoint. Both Electric Power Division and Machinery Division conducted the P and D in close relations with electric power industry until 1970, when the two Divisions were reorganized according to the needs of the times to give birth to the Energy Division, which initiated such R and D of innovative energy technologies as were hardly undertaken by private enterprises. In 1978 the Energy Systems Division was established to share the activities with the Energy Division. At present the ETL's R and D activities on energy technologies are devided into three categories: (1) alternative and renewable energy (Sunshine Project), (2) energy conversion (Moonlight Project) and (3) nuclear fusion. Some important points to be considered in promoting these P and D activities are given. (author)

[en] Based on the Ordinance of Minister of International Trade and Industry No.62, ''determining the technical standards concerning atomic energy facilities for power generation,'' the details were determined. The detail items were as follows; the effective dose of external radiation on living bodies, the concentration of radioactive materials in air or water, the density of radioactive materials on the surface of a contaminated matter, the permissible effective dose of exposure of living bodies, and the standards of the materials for vessels and pipes in atomic energy facilities. This notification has become effective from 1 July 1972. (J.P.N.)

[en] We have developed a new method for identifying the effects of calendar year, plant age and commercial operation starting year on the costs and performances of nuclear power plants and also developed an analysis system running on personal computers. The method extends the Bayesian cohort model for time series social survey data proposed by one of the authors. The proposed method was shown to be able to separate the above three effects more properly than traditional methods such as taking simple means by time domain. The analyses of US nuclear plant cost and performance data by using the proposed method suggest that many of the US plants spent relatively long time and much capital cost for modification at their age of about 10 to 20 years, but that, after those ages, they performed fairly well with lower and stabilized O and M and additional capital costs.
