Containment cooling system and containment and reactor pressure vessel joint cooling system

摘要

The present invention relates to a containment cooling system and a combined cooling system of a containment vessel and a reactor pressure vessel, the containment vessel cooling system comprising an internal heat exchanger (1), a riser pipeline (2), a polling pipeline (3) The isolation valves 4 and 5, the cooling water tank 6, and the air-cooled condenser-cooler 7 are connected. The combined cooling system of the containment vessel and the reactor pressure vessel includes the containment vessel cooling system and the reactor pressure vessel cooling system. The cooling system provides long-term and effective cooling to the containment vessel and the reactor pressure vessel simultaneously without the need to provide external power in the event of an accident, so that, under the condition that there is no artificial interference and no external cooling measures in the event of an accident, Ensure that reactor pressure vessels are always in safe condition.
