In order to study the future nuclear energy utilization scenarios, it is necessary to analyze the front-end, reactor operation, and back-end of the nuclear fuel cycle in an integrated manner. On the other hand, the nuclear fuel cycle simulation codes that have been developed in various institutes are specialized in front-end scenario analysis, and it is not to provide user flexible analysis of the back-end simulation. Therefore, Tokyo Institute of Technology and Japan Atomic Energy Agency have jointly developed NMB4.0, a computational platform for integrated and flexible analysis of front-end to back-end scenarios of nuclear fuel cycle. In this presentation, the general functions and computational performance of NMB4.0 were reported.
