Experiment research of different power passive containment heat removal system
Comparing the passive containment heat removal system(PCS)between Linglong No.1,and Hualong pressurized reactor 1000,they have the same principle but different system functions and design criteria.In order to master the key factors that affect the heat transfer capacity and operation of the system,based on the characteristics of different projects,this paper studies and analyzes the typical phenomena in the design of the passive containment cooling system of HPR1000 and Linglong No1,from the aspects of comprehensive performance experimental requirements and experimental results.Lowering the cooling water level can improve the heat exchange capacity of the system,the resistance of the cold pipe section is more sensitive to the heat exchange capacity,and the closing scheme of isolation valve in cold pipe section may have certain risks when it is opened.Therefore,the influencing factors that need to be paid attention to in the follow-up optimization research and design are put forward.The conclusions in this paper can be used to guide related system design.
