Compilation of the data book on light water reactor benchmark to develop JENDL; Utilization and extension of 2017 report (JAEA-Data/Code 2017-006)

Reactor Integral Test Working Group, JENDL Committee

The reactor integral test working group organized in the JENDL committee has prepared the benchmark database which is devoted to performance evaluation and validation testing of JENDL-5 regarding simulation of nuclear fission reactors applications, and the report "JAEA-Data/Code 2017-006" for the aforementioned benchmark database was published in 2017. After the publication of the report, the benchmark database has been extended energetically in Japan Atomic Energy Agency under the cooperation of the JENDL Committee. The database contributes improvement of reliability of JENDL-5. This report is a summary of the aforementioned extended database, and the report is expected to be efficiently utilized for not only the developments of nuclear data library in future but also integral tests of released nuclear data libraries.
