In-vessel melt-water interaction caused by the failure of the crust above the core support plate under molten pool Part 1: Choice of the solution method

摘要

The first part of this work describes a methodology used to estimate the risk of melt water interaction for in-vessel scena- rios. After presenting the available information for the admis- sible mechanical upper head impact energy and for the avail- able thermal energy for the EPR several inherent limitations are discussed for transferring the available thermal energy into mechanical energy and to transport it up to the upper head.
