摘要: 针对CPR1000核电机组反应堆水池和乏燃料水池冷却以及处理(PTR)系统在某些情况下存在失去设备冷却水的风险,从冷却水源单一的角度分析机组PTR系统存在的问题,结合PTR系统现有的设备,创新性设计出采用其他冷却水源的备用冷却方式。分析研究表明,该设计方案提高了持续冷却乏燃料水池的可靠性,为PTR系统冷却方式增加了多样性和冗余性。

Abstract: In view of the risk of loss of component cooling water (RRI) facing the reactor cavity and spent fuel pit cooling and treatment system (PTR) of the CPR1000 units in China in certain cases, this paper analyzes the problems of the unit PTR from the perspective of single cooling water source, and considering the existing PTR equipment, creatively designs the backup cooling mode using other cooling water sources. As demonstrated by the analysis and study, this design improves the reliability of continuously cooling the spent fuel pool, and the diversity and redundancy of the PTR cooling modes.-
