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

摘要

The present invention relates to a containment cooling system and an associated cooling system of a containment vessel and a reactor pressure vessel, said containment cooling system mainly comprising an internal heat exchanger (1), a rising pipeline (2), a polling pipeline (3), It consists of connecting the isolation valves 4 and 5, the cooling water tank 6 and the air-cooled condensing-cooler 7. The associated 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 containment vessels and reactor pressure vessels at the same time without the need to provide external power in the event of an accident, under conditions of no artificial interference and external cooling measures in the event of an accident. Ensure that the reactor pressure vessel is always in a safe condition.
