CORE MELT COLLECTOR

摘要

A floor of a collection chamber adjoining a pressurized vessel containing a nuclear reactor core is provided with recesses into which core melt is conducted in the case of meltdown for storage until final disposal. The recesses are separated by ribs of reduced height and over which the melt flows so that thin regions are provided above the ribs and between the pieces of the solidified melt which can be readily cut through or broken for separation of the pieces and removal.
