摘　　要：非能动安全壳热量导出系统(PCS)作为三代核电厂重要的安全系统,用于事故后安全壳的非能动冷却。利用大型安全壳综合试验装置,可开展安全壳内复杂的热工水力现象与安全系统之间耦合行为的研究。本文利用大型安全壳综合试验装置开展了PCS换热器冷凝水收集装置对PCS排热影响及收集率试验。结果表明,在工况范围内,换热器下方安装冷凝水收集装置对PCS的换热能力没有明显的不利影响,且其收集率较高。Passive containment heat removal system(PCS)is an important passive safety system of three-generation nuclear power plants for containment cooling.Using the large-scale containment integrated test device,the coupling behavior research between complex containment thermal hydraulic phenomenon and safety system can be carried out.The effect of condensate collection device on the heat rejection of PCS and the collection rate test were introduced using the containment integrated test device.The test results show that the condensate collection device installed under the heat exchanger has no obvious adverse effect on the heat exchange capacity of PCS in the research condition of this paper,and the collection rate is high.
