摘　　要：“华龙一号”非能动安全壳热量导出系统(passive containment heat removal system,PCS)和“玲龙一号”非能动安全壳热量导出系统设计原理相同,但系统功能和设计准则不尽相同。为了掌握影响系统换热能力和运行的关键因素,本文结合不同项目的特点,从综合性能实验需求和实验结果等方面,研究、分析“华龙一号”非能动安全壳热量导出系统与“玲龙一号”非能动安全壳热量导出系统设计中的典型现象,发现降低冷却水箱水位可以提升系统的换热能力、改变冷管段阻力对系统的换热能力更敏感和冷管段隔离阀关闭方案在开启时可能会有一定的风险,从而提出后续优化研究和设计中需要重点关注的影响因素。文中结论可用于指导相关系统设计工作。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.
