As a study on long-term safety of geological disposal of high-level waste (HLW) generated during reprocessing spent mixed oxide fuel in light water reactors (MOX-LWRs), two types of HLW are considered. One is HLW generated from MOX-LWR reprocessing and another is blended MOX-UO
HLW generated during reprocessing process whereby MOX fuels are diluted by UO fuels. Radionuclide migration analyses for those two HLWs are conducted, and commonalities and differences between two HLWs in the viewpoint of long-term safety are discussed.

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).
