Pressure suppression apparatus for reactor container

摘要

There is provided a pressure suppression apparatus for a nuclear power plant. The pressure suppression apparatus includes a reactor vessel, reactor container, drywell cooler, and a first fan. The reactor vessel stores nuclear fuels for electric power generation. The reactor container stores the reactor vessel and defines drywell rooms. The drywell cooler cools air in the drywell rooms so as to suppress pressure in the drywell rooms. The first fan guides air in the drywell rooms into the drywell cooler. The pressure suppression apparatus of the present invention further includes a second fan for exhausting non-condensable gas among air from the drywell cooler. The second fan is operated by an emergency power supply, and therefore the second fan can continue to exhaust non-condensable gas if the first fan stops. IMAGE
