摘要
针对改进型三环路压水堆(CPR1000)核电厂在某些工况下可能丧失对乏燃料水池冷却功能的情况,以岭东核电厂为例,分析CPR1000换料水池和乏燃料水池冷却和处理系统(PTR)的设计基准、系统功能及缺陷,并结合技术规范的要求,提出PTR的改进措施。分析表明,CPR1000核电厂乏燃料水池冷却问题的原因是PTR设计没有充分考虑冗余性。建议从提高PTR冷却回路换热能力和降低乏燃料水池完全失去冷却风险方面进行改进。
The spent fuel pool of the CPR1000 type nuclear power plant （ pressure water reactor ） may loses it＇s cooling function in some conditions. The author uses Ling Dong NPP as the example to analysis the design basis, system functions and defects of PTR, and gives some suggestions to improve the PTR with considering the requirements of technical specification. The results show that the spent fuel pool cooling problem is because that the designer does not consider the redundancy of the PTR completely. The author suggests to improve PTR cooling capacity and reduces the risk of losing cooling of spent fuel pool.
