Description

The thermal-hydraulic behaviour of a mass of molten corium is investigated, and the purpose of this study is to show the possibility of a calculation with the classical k-epsilon model far from the wall, and a special treatment for heat transfer near the wall. A transient numerical analysis is first presented. Thermal-hydraulic quantities, such as velocity field and temperature distribution, are determined in the corium. The thermal behaviour of the wall is then investigated together with a stratified oxidic-steel pool in a cylindrical geometry. 6 figs., 7 refs
