Receptacle construction for water nuclear reactor, uses porous mineral such as ceramic foam between receptacle and reactor core

摘要

The reactor includes a grid or horizontal perforated plate for the spreading and dispersion of corium (36). The reactor also contains a basin shaped receptacle (20) separated from the reactor core (12) to allow the circulation of water, the receptacle is partially made of refractory material. The receptacle contains a porous mineral (30) such as a ceramic foam that can lower the temperature of corium.
