[3J08] Deepening Understanding of Ex-Vessel Corium Behavior by Multi-Physics Modeling
(2)Overview and Progress on Spreading Analysis by MPS Method
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.
