原子力船定係港の計画概要

Brief descripfion is given of the plan of construction of the proiected servicing home port for the nuclear ship. The location selected is the Port of Ominato in the northern part of Honshu and will be constructed in parallel with the building of Japan's first nuclear ship.The port will support the operation of the nuclear ship with her shore servicing facilities, which will be prepared to refuel the marine reactor and treat radioactive wastes, as well as repair the reactor plant when necessary.Among the major facilities to be constructed are a wharf crane, a service building for fuel handling and storing facilities, a waste freatment plant, a sub-staion and an office building.

475. 鉛の接合部におけるガンマ線の漏洩,(II)

In continuation of a series ot mockup tests for the first Japanese nuclear ship, reactor γ-ray leakage through a double-bend two-dimensiond passage in a leqd slab was experimentally studied. This zig-zag slit channel is recognized to be an effective device against γ-ray leakqge at shield seams. Such leakage may occur through straight passages with normally incident γ-rays, or else with oblique incidence, in the form of streaming.In the case of zig-zag channel, it should be noted that there exist certain incident angles at which the shielding effect is morkedly impaired. The components of penetration calculated by ray-analysis method have been compared with experimental results. The existence of a slit in a lead slab increases scattered γ-rays, which are localized near the shield surface, but which spread widely with increasing distance from wall.

A Nuclear-Fueled Steam Generator-Superheater for Merchant Ship Propulsion

The 630A is a nuclear steam generator-superheater of about the same size and somewhat heavier than the conventional boiler which it can replace in merchant ships. It has a gas primary cycle, transferring heat from the reactor to a once-through boiler-superheater. Feedwater delivered to the boiler is discharged as high superheat steam (1500 psi--1000 F). The 630A technology stems from the nuclear aircraft and land-station technologies. It has gone through a series of design iterations. This paper describes the Mk IV. The latest version, the Mk V, with improved economics is now proposed for ship installation. The paper discusses the general considerations of maritime nuclear propulsion, problems in achieving full utilization, and presents an economic comparison of 13,000-dwt nuclear and conventional ships over a range of speeds.

XIII. 舶用炉開発計画

The progress of marine reactor development is reviewed from the technical point of view, and the main features of recently developed marine reactors are outlined.The program for developing the first nuclear ship in Japan is described, and the specifications are given of the reactor whose preliminary design has been prepared by the Japan Nuclear Ship Development Agency. It has been decided that the reactor to be installed should be the indirect cycle light water type. The basic policy is to assure safety in operation, and due consideration for incorporating domestic technology in design and construction.

THE FUTURE OF NATIONAL AND INTERNATIONAL REGULATIONS COVERING THE USE OF IONIZING RADIATIONS.

Fields in which regulations covering the use of ionizing radiations are already in force in the U.K. and fields still unregulated, or only partly regulated, in which there is scope for future regulations, including the practice of medicine and allied professions; research laboratories; nuclear ships; international cortrol of disposal of radioactive waste in the sea; agriculture--- the role of Government Departments---the disadvantages of over-regulating an industry---the possibility of the relaxation of regulations as knowledge and experience increase are discussed.

原子力海洋観測船兼補給船の試設計

In 1961, the Japan Nuclear Ship Research Association made a contract with the Science and Technical Agency of Japanese Government, on the trial design of nuclear powered oceanographic and supply ship as one of the latter's projects for the peaceful use of nuclear power. The association organized a comittee to supervise the designing in which the author presided as the chairman.The following presentation is an outline discription of the design which was completed in July, 1962.The ship has 6, 350 gross tonnage and is equipped with a water cooled, water moderated pressurized water reactor which has 35 MW thermal output and produces 10, 000 s.h.p. The weight of the trial design was not placed in developing a new type of marine reactor nor in detailing about conventional part of a ship's design.The main object was to study about the feasibility of a comparatively small nuclear powered vessel with proved-type-reactor with satisfactory safety and also to find out where would the problems, technological and legal lie if we were to construct such a ship in a very near future.We believe that aim of the project has been attained satisfactorily.

General Assembly

Report to the General Assembly: The fifth report of the International Atomic Energy Agency (IAEA) to the UN General Assembly covered the period from July 1, 1960, to June 30, 1961. The report stated that most of the Agency's programs were now firmly established and that the Agency had reached the stage where it was capable of further developing certain of its operations. The direction and scope of such development would be determined largely by the rate of advance of nuclear technology, by the extent to which the Agency might be able to serve as a means for promoting scientific cooperation between the leading nuclear powers, and by the support which it received from its members. Events of interest in the Agency's work in the last year included the completion of studies of nuclear power prospects in Finland and the Philippines, technical conferences on the economics and technology of small and medium power reactors, and conferences on nuclear ships. The Agency was able to report reasonable progress in promoting the uses of radioisotopes and radiation under safe conditions in the less developed areas. Progress had also been made in giving help or guidance to member states on questions of safety and pretection against radiation hazards. The Agency had paid special attention to establishing standards of basic radiological safety, safety of reactors, and standards for the disposal of low-level radioactive waste. Under the scientific and technical information program, the Agency had held thirteen meetings in the period under review. In 1960 the Agency had made available an estimated $2,560,000 for technical assistance in the form of equipment, experts, and fellowships.

General Assembly

Report to the General Assembly: In accordance with a resolution adopted during the fourth regular session of the General Conference of the International Atomic Energy Agency (IAEA), the fourth report of IAEA to the UN General Assembly consisted of the annual report of the Board of Governors to the General Conference, covering the period July 1, 1959, to June 30, 1960, together with a supplement dealing with developments, including action taken by the General Conference, during the period July 1 to September 30, 1960. The report noted that during the period under review the preparatory activities of the Agency had begun to bear fruit and that in most domains the year had been the first full year of normal operations. One of the main goals of the Agency, the report continued, was to foster the safe use of nuclear power under economically competitive conditions, but in this area there were still innumerable problems to overcome. Since the cost of generating electricity from nuclear power plants, although steadily declining, was still substantially higher than that of producing conventional power except in a few special cases, the earlier nuclear power plans of a number of countries had been revised and construction of plants was not proceeding at the rate foreseen some years ago. With regard to reactor technology, the Board reported that work was being done to improve the performance of reactors and to reduce their costs of operation by detailed technical modifications, although the cost of research on advanced reactor concepts was so high that only a very few major industrial countries had the necessary material resources to conduct such research. While the Board considered it unlikely that nuclear—propelled ships would become economically competitive with conventional ships in the near future, progress had been made in this sphere in the year under review, as witnessed by the commissioning of a nuclearpropelled ice-breaker and the launching of the first nuclear merchant ship.

Safety on the Nuclear Ship Savannah

BS>The nuclear-powered merchant ship, Savannah, is a combination passenger-cargo ship of the mariner class. It is 595 feet long, has 78-foot beam, and will have a fully loaded displacement or 21,800 tons. the ship will have a sea speed of 20 knots and a cruising radius in excess of 100,000 miles. With a 124-man crew, and additional space for observers and technicians, she will also be able to carry 60 passengers. The NS Savanaah was launched on July 21, 1959. After a comprehemsive test program and outfitting, sea trials are scheduled for the spring of 1960. The construction of the nuclearpowered ship posed new and unique problems in design and operation. Complete containment, retertion of wastes, and other nuclear and nautical safeguards incorporated to ensure maximum safety are discussed. (C.H.)
