[1F11] Development of molten core spreading model at severe accident
Keywords:CFD, MCCI, Spreading, Molten Core
In severe accidents, spreading length of the molten core on the floor of the reactor cavity is affected by viscosity change, and floor melting. Accurate prediction of molten core spreading length is important for the safety enhancement. Validation results of spreading length are presented in this paper.
