Apparatus for catching and cooling a melt

摘要

An apparatus is described for catching and cooling a melt, in particular a core melt in a containment of a nuclear power plant. A porous body with which the melt comes into contact is provided. A pre-pressurized coolant is fed to the porous body so that the cavities in the porous body are filled with the coolant. After contact between the melt and the porous body, the pre-pressurized coolant penetrates into the melt and as a result leads to fragmentation, solidification and long-term cooling.
