評価済み核データ・ライブラリー,JENDL-1の概要

The First Version of Japanese Evaluated Nuclear Data Library (JENDL-1) was released in autumn 1977. JENDL-1 includes 72 nuclides most of which are needed for the study of the fast breeder reactors. Evaluation works on nuclear data of these nuclides had been performed not only by working groups of Japanese Nuclear Data Committee (JNDC), but also by individuals in various organizations in Japan. A compilation group for JENDL-1 was organized in JNDC at April 1974 in order to collect all available evaluations in the world, to select the most reliable data among them, and to modify some parts of the selected data, if necessary. Many persons helped the compilation group to provide the eva1uated data. The compilation-group members made reevaluations and recalculations when there were no relevant data. JENDL-1 was thus accomplished, and its reliability was examined through benchmark tests on the integral data. Results of this examination were fairly satisfactory, and showed that JENDL-1 could serve practical use.
