The seminar was divided into seven sessions dealing with the following subjects: (1) Nuclear data activities, (2) Nuclear data for nuclear fuel cycle, (3) Nuclear data for reactor design, (4) Nuclear data evaluation, (5) Fission phenomena, (6) Utilization of nuclear data in other fields, and (7) Poster session: Nuclear Data Files Available from JAERI Nuclear Data Center. This seminar was planned to invite a few experts on nuclear data from the Asian-Pacific region. Unfortunately, no one could participate in the seminar from abroad, but some papers were contributed from both China and Australia. These contributed papers are included in the Proceedings.

It is over twenty years since JNDC was organized, and so, in this opportunity, development of JNDC is recollected. Recent activities are also presented focusing the discussion on the evaluation work for JENDL-3. Nuclear data measurement activities in Japan are gradually increasing recently. Activities in each organization are introduced. 1. Introduction The Japanese Nuclear Data Committee (JNDC), organized in February 1963, is a standing committee of the Atomic Energy Society in Japan. The committee is concerned primarily with the activities related to the nuclear data of interest to the development of the nuclear energy program. The committee has at present the following substructures: an executive committee, three subcommittees on "nuclear data", "reactor constants" and "nuclear structure and decay data", ten working groups under the subcommittees, and three individual groups for CINDA, WRENDA, and the compilation of the Japanese Evaluated Nuclear Data Library (JENDL). The operation of the committee meetings and the activities of the working groups are sponsored by the Japan Atomic Energy Research Institute (JAERI), however, the whole activities of JNDC are largely supported by the voluntaries of its members. The Nuclear Data Centre of JAERI has been taking charge of the secretariat of JNDC. In this report, development of JNDC is reviewed chronologically. Recent activities of JNDC are also presented. There have been many activities, but the report will be focused on the nuclear data e\aluations. Recent activities on nuclear data measurements in Japan are briefly introduced. - 1 - JAERI-M 85-035 2. Chronological Review of JNDC Activities Research on the nuclear data in Japan had been carried cut through measurements before the Japanese Nuclear Data Committee (JNDC) was organized in 1963. In the application fields such as reactor physics, reactor engineering, etc., on the other hand, researchers had used some foreign nuclear data files whose sources were not always evident. Those data files irritated researchers who wanted to investigate problems deeply. They felt that it was necessary to have their own data files so that they could research and discuss matters on the basis of them. JNDC was organized in order to collect, compile and evaluate the nuclear data, and to provide them to users. Its first project was to calculate unknown nuclear data theoretically. Our government supported this project, and supplied it with a research fund for peaceful use of nuclear energy. JNDC utilized this fund- to develop some nuclear model codes for calculation of the fast and thermal neutron cross sections, and to study various models, systematic trends of their parameters, etc.
