Résumé :	Melt propagation and relocation in a rubble bed has been investigated theoretically and experimentally , a droplet flow model was used to simulate the melting and freezing process in a degraded nuclear reactor core , expe simulatingrimentsthe freezing process in a rubble bed were performed to assess the theoretical model , in particular the effect of subcooling , superheat and mass delivery rate on freezing were studied , a correlation was developed to predict the contact area as function of thermal properties of both solid and liquid including superheat , subcooling as well as the rubble bed porosity , a simplified model was also developed and implemented in the April mod 2 computer code , the results of testing showed that refreezing of molten corium may substantially delaya the release of melt from the reacto core
