<P>PROBLEM TO BE SOLVED: To provide nuclear power plant which suppresses increase in pressure and temperature at the inside of a containment vessel when a water supply pipe in the containment vessel is broken. <P>SOLUTION: Nuclear power plant 10 includes: a reactor pressure vessel 11 for making furnace water steam by nuclear reaction heat; a high-pressure turbine 13 and a low-pressure turbine 14 for converting thermal energy of the steam to kinetic energy; a condenser 15 for cooling the steam having released the thermal energy and making the steam condensed water 16; piping 30 through which the condensed water 16 going back to the reactor pressure vessel 11 from the condenser 15 flows; a detection part 42 for detecting that the condensed water 16 has spilled into the inside of a containment vessel 12 which stores the reactor pressure vessel 11; and a water storage part 40 for ejecting cooling water 48 to the piping 30, on the basis of the detection result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
