Abstract

Analysis of penetration and solidification of hot core-materials mixture into a colder flow channel during core disruptive accidents (CDAs) is one of the major concerns for the safety design of liquid-metal cooled reactors (LMRs). In order to model the freezing behavior of melt of the postulated disrupted core in a CDA of an LMR and provide data for the verification of a fast reactor safety analysis code (SIMMER-III), a series of basic experiments was performed for the freezing behavior of melt during penetrating into a flow channel. In the experiments, a low-melting-point metal alloy (viz., Wood's metal) and solid metal particles mixtures were used as a stimulant melt, while a stainless-steel seven-pin bundle was used as a flow channel. The melt penetration length and the proportion of frozen mass distribution into the flow channel were measured. The comparison between SIMMER-III simulation and its corresponding experiment indicates that the SIMMER-III code can reasonably represents the melt penetration, relocation and freezing behavior as observed in the experiments. The validation of several key models of SIMMER-III was also discussed for treating melt penetration and freezing behaviors of the solid-liquid multi-phase flows.
