<P>PROBLEM TO BE SOLVED: To supply cooling water without using an external power source when sprinkling water from an upper side to an outer surface of a reactor containment vessel in the case of coolant leakage. <P>SOLUTION: In nuclear facilities including a reactor vessel 2 which contains a reactor core and a reactor coolant, a reactor containment vessel 4 which accommodates the reactor vessel 2 and a leakage cooling system for cooling the reactor containment vessel 4 from the outside when the reactor coolant is leaked from the reactor vessel 2. The leakage cooling system comprises a cooling water supply pump 141 which transfers cooling water for cooling an external wall surface of the reactor containment vessel 4 to the upper side of the reactor containment vessel 4, and a cooling pump motive force supply section which supplies a motive force to the cooling water supply pump 141 by utilizing heat from the leaked reactor coolant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
