Title: PASSIVELY-OPERATED CORIUM COOLING APPARATUS
Abstract:
The present invention relates to a passively-operated corium cooling apparatus comprising: a nuclear reactor vessel; a core catcher positioned at the lower part of the nuclear reactor vessel; a flow path structure positioned at the lower part of the core catcher, and having a coolant flow path filled with a coolant; and a coolant tank communicating with the flow path structure through a first pipe and supplying coolant to the coolant flow path through the first pipe, wherein the coolant flow path is divided into a first flow path adjacent to the core catcher and a second flow path spaced from the core catcher, and the first flow path and the second flow path are connected to each other.
