This report describes the mechanics of automatic circulating angling machines for skipjack devised by the authors and a result of angling tests. These devices can economize the angling space, that is the fish caught are gathered at one space so that the process from angling to storage is systematized. The authers would like to report the result of series of the experiments. 1) Two kinds of angling machines were made for experiments, one of which is the vertical circulating machine (S.V.M) and the other is the horizontal circulating machine (S.H.M). 2) Angling tests with both machines were carried out during the period from 1965 to 1975 in the southern area of the Pacific Ocean. There was no difference in angling ability between the two machines and well-trained fishermen under the same catching conditions. 3) The S.H.M proved to be more efficient than the S.V.M in performance other than angling. 4) It is ncessary to improve the S.H.M to prevent unhooking, before it is used practically. Also the bulwark of the vessel should be remodeled to fit the S.H.M.

集光型太陽熱発電(CSP)は,反射鏡で集光した太陽光をレシーバで熱へと変換し,一般には蒸気タービンを回して発電する技術である。本システムでは,蓄熱システムやボイラを組み合わせることにより,太陽が照っていない時間帯にも比較的低コストの発電が可能である。したがって,CSPは,電力需要曲線に合わせた電力供給が可能であり,ディスパッチャビリティが高い発電システムである。CSPでは太陽から直接地表に到達する直達光のみ利用できることから,中東・北アフリカ,米国南西部などサンベルトと呼ばれる地域で高効率の発電が可能であり,発電ポテンシャルも膨大である。CSPで得た電力を離れた地域で利用するため,北アフリカで発電した電力を高圧直流送電でEU諸国に送るデザーテック計画も進行している。

A special committee on “Research on the analysis methods for accident consequence of nuclear fuel facilities (NFFs)” was organized by the Atomic Energy Society of Japan (AESJ) under the entrustment of Japan Atomic Energy Agency (JAEA). The committee aims to research on the state-of-the-art consequence analysis method for Probabilistic Safety Assessment (PSA) of NFFs, such as fuel reprocessing and fuel fabrication facilities. The objective of this research is to obtain the useful information related to the establishment of quantitative performance objectives and to risk-informed regulation through qualifying issues needed to be resolved for applying PSA to NFFs. The research activities of the committee were mainly focused on the analysis method of consequences for postulated accidents with potentially large consequences in NFFs, e.g., events of criticality, spill of molten glass, hydrogen explosion, boiling of radioactive solution, and fire (including rapid decomposition of TBP complexes), resulting in the release of radioactive materials into the environment. The results of the research were summarized in a series of six reports, which consist of a review report and five technical ones. In this technical report, the research results about basic experimental data related to the consequence of the radiolytically generated hydrogen gas explosion postulated in the radioactive solution reserve tank caused by the loss of dilution air supply were summarized.
