NUCLEAR REACTOR LONG-TERM COOLING SYSTEM AND NUCLEAR PLANT HAVING THE SAME

WIPO Patent Application WO/2020/050519

A1

Disclosed are a nuclear reactor long-term cooling system and a nuclear plant having the same. The nuclear reactor long-term cooling system, comprises: a lower containment area formed to enclose a reactor coolant system, and configured to prevent steam containing radioactive substances generated from the reactor coolant system from leaking to a path other than a discharge unit; an In-Containment Refueling Water Storage Tank (IRWST) disposed outside the lower containment area, and having refueling water stored therein; and a discharge pipe configured to connect the lower containment area to the IRWST, and to discharge steam of the lower containment area to the refueling water when an accident occurs. The nuclear plant may have an enhanced safety.
