Some Problems on the Thermal State of the External Corium Catcher and on Selecting Its Optimum Structure

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

The thermal state of a molten corium and of the walls of the storage chamber of an EPR external corium catcher has been analyzed. It is shown that the strong nonuniformity of distribution of the heat‐flux density over the surface of the storage chamber of the catcher makes it impossible to coordinate with the required degree of accuracy the processes of melting of a taphole and the processes of dilution of the oxide component of the melt (required to ensure the inverse stratification of the corium) with sacrificial concrete. Additional technical measures are required to ensure the effectiveness of the catcher.
