Requests on Nuclear Data in the Backend Field through PIE Analysis

摘要

From studies on nuclear data related to the backend field based on activities of our WG, we have the following remarks. 1. The burnup codes used in our WG such as SRAC, SWAT and ORIGEN with cross sections considering actual neutron spectrum has been verified through PIE analysis based on JENDL-3.2 2. It is possible to reduce large margin assumed in the present criticality analysis for spent fuels using the verified burnup codes 3. It is desired that the nuclear data files for Cm-242 and Cm-244 will be revised to improve the accuracy of PIE analysis Our wishes is to use improved nuclear data to be solved the problems in our studies.
