Melt Eruption Modeling for MCCI Simulations

Abstract

This paper presents results of an investigation into the melt eruption phenomenon that could occur during molten corium concrete interactions (MCCI). Melt eruptions have occurred during many laboratory scale MCCI tests and have a large potential impact on the accident progression. The results of a low temperature experimental investigation of melt eruptions are provided. Models which predict melt entrainment and the number of eruption sites are presented.
