According to an embodiment, a nuclear power plant has a core (1); a reactor pressure vessel (2); a dry well (4); a wet well (5); a vacuum breaker (9); a containment vessel (3) including the dry well (4), the LOCA vent pipe (8), the wet well (5), and the vacuum breaker (9); a cooling water pool (13) placed outside the containment vessel; a heat exchanger (16) at least partially submerged in cooling water (14); a gas supply pipe (20) connected to the inlet plenum (17) of the heat exchanger (16) and the dry well (4); a condensate return pipe (21) connected to the outlet plenum (18) of the heat exchanger (18) and the containment vessel (3); and a gas vent pipe (22) connected to the outlet plenum (18) of the heat exchanger (16) and an outside of the wet well (5) so that non-condensable gas inside the heat exchanger (16) is released out of the wet well (5). The gas vent pipe (22) is not connected to the wet well (5). |
