Experiment Research on Effect of Condensate Collection Device in Passive Containment Heat Removal System

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.
