Improvement on the prediction accuracy of transmutation properties for fast reactor core using the minor actinides irradiation test data on the JOYO MK-II core

Sugino, Kazuteru

For a validation of MAs nuclear data and improvement on the prediction accuracy of MAs transmutation properties in fast reactor cores, the MAs sample irradiation tests data of Joyo were utilized. Result of their analyses showed good agreement with experimental value, which indicates that the MAs cross sections in JENDL-3.3 are almost satisfactory for an application to fast reactor cores. Further, the present study clarified that the utilization of those data with cross section adjustment technique has the potential to reduce the uncertainty of MAs transmutation properties in fast reactor cores to less than half.
