*Akifumi Yamaji1, Masahiro Furuya2, Yuji Ohishi3, Guangtao Duan1 (1. Waseda University, 2. Central Research Institute of Electric Power Industry, 3. Osaka University)

Keywords:severe accident of a nuclear reactor, MPS method, ex-vessel corium behavior, corium spreading, MCCI

MPS method (one of the particle methods) is being developed for mechanistic modeling of ex-vessel corium behavior (spreading and MCCI) by combining with scale-effect test and the basic UO2 fuel property experiment. The program overview and Progress on Spreading Analysis by MPS Method will be reported.
