Takeshita Laboratory, Tokyo Institute of Technology, has been improving the Nuclear Material Balance code (NMB code) developed by Japan Atomic Energy Agency based on the knowledge of the nuclear fuel cycle simulation conducted so far. The previous NMB code was specialized in the evaluation of mass balance of actinide and lacked the function of back-end scenario analysis. In this improvement, 3 main points were researched and developed that (1) selection of FP nuclides to be introduced into the NMB code, (2) development of a nuclear data library preparation tool for the NMB code, and (3) burnup calculation and its error evaluation. In this presentation, we reported the results of the studies in (1) to (3).
