Abstract

Abstract

Based on the experimental phenomena,an improved lumped parameters mathematic model has been set up and programmed for the analysis of the cooling mechanism of the debris formed of moltenmaterial,which dumped into the lower head of the vessel during a severe accident.The proposed mode has been verified by simulating the results of ALPHA tests.Results indicated that the proposed model can well predict the cooling mechanism of the debris formed of molten material,which located in the lower head of the vessel during a severe accident.
