Abstract

According to an embodiment, a reactor pressure vessel depressurization system (110) has: a main steam safety relief valve (6), a main steam safety relief valve driving gas pipe (11); a three way electromagnetic valve (10) having the first connection port (10a); a driving gas feed pipe (12) connected to the second connection port (10b); and a containment vessel external connection pipe (13) connected to the third connection port (10c) and extending to the outside of the reactor containment vessel. The three way electromagnetic valve (10) is either in the first communication state the first connection port (10a) communicates with the second connection port (10b) or in the second communication state where the first connection port (10a) communicates with the third connection port (10c). The containment vessel external connection pipe (13) has an open communication section (14) open in normal operation and capable of being closed, and an external gas receiving section (15) capable of receiving outside second driving gas.
