PROBLEM TO BE SOLVED: To provide a reactor cooling device having high efficiency of cooling and high sureness of operation in removing decay heat of the reactor without external support. SOLUTION: The device has a plurality of evaporators 5 arranged in primary cooling water for cooling the core 3 of a reactor vessel 2, a PSGC 9 arranged in cooling water 8 in a water tank 7 of a cooling tower 6 so as to be higher position than the evaporator 5, pipes 10a and 10b connecting the evaporator 5 and the PSGC 9 and circulating secondary cooling water and valves 19A and 20A provided to the pipes 10a and 10b. To the pipe 10b on the side of supply water from the PSGC 9 to the evaporator 5, a supply water header 32 storing a plenty of secondary cooling water is provided. COPYRIGHT: (C)2006,JPO&NCIPI
