A passive concrete containment cooling system (100), comprising a heat exchange loop system (130) and a condensate recovery system (120); the heat exchange loop system (130) hermetically runs through the containment (110) to export heat out of the containment (110); the condensate recovery system (120) is disposed within the containment (110) and communicates with a reactor pile (112). High energy steam generated during an accident is exported via the heat exchange loop system to an ultimate heat sink in the atmospheric environment; the condensate recovery system recovers the condensate generated from condensation in the heat exchange loop system and/or on the inner wall of the containment, and automatically injects the condensate into the reactor pile, to realize passive injection into a reactor pile over a long period of time, and realize export of waste heat from a containment in accidents without relying on power such as an external AC power source, thus improving safety of a nuclear power station, and especially improving protection capabilities under the extreme conditions of a complete power outage and complete loss of a cooling chain. |
