CONTAINMENT COOLING SYSTEM AND CONTAINMENT AND REACTOR PRESSURE VESSEL JOINT COOLING SYSTEM

摘要

The present invention provides a containment cooling system and a containmentandreactor pressure vessel joint cooling system, wherein the containment coolingsystemis mainly formed by connecting an internal heat exchanger (1), a risingpipeline (2), afalling pipeline (3), isolation valves (4, 5), a cooling water tank (6) and anair coolingcondenser-cooler (7). The containment and reactor pressure vessel jointcoolingsystem includes the containment cooling system and a reactor pressure vesselcoolingsystem. The cooling system does not need to power provided externally, and canprovide long-term effective cooling for a containment and a reactor pressurevessel atthe same time in the case of an accident, thereby ensuring that when theaccidentoccurs, under the condition of no human intervention and no input of otherexternalcooling measures, the reactor containment and the pressure vessel are alwaysin a safestate.
