A uranium enrichment model assuming a centrifugal separation cascade has been implemented in a nuclear fuel cycle simulator NMB4, which has been developed by JAEA and Science Tokyo. This model enables calculation of fresh fuel composition obtained by centrifugal enrichment of uranium containing multiple nuclides. The model was used for mass balance analysis related to the utilization of recovered uranium in future nuclear energy use scenarios in Japan. In this presentation, the validation of the model and the results of the mass balance analysis will be reported.
