Abstract

A brief description of the HEFEST-ULR code and numerical results for corium behavior in a core catcher for the VVER-1200 (NPP-2006 project) are presented. Physical, chemical, and thermal processes during corium pool formation and cooling in the core catcher are examined for the case of severe accidents in NPP-2006 with the VVER-1200. Basic corium parameters, including its composition, structure, temperature evolution, density, and aggregative state, are determined. The minimum margin for critical heat flux at the external surface of the core catcher is estimated.
