摘要
日本福岛核事故后,乏燃料池(SFP)在事故中的安全性得到广泛的关注。AP1000乏燃料池冷却系统(SFS)是一非安全相关的系统,不需在事故后运行以缓解设计基准事故。但乏燃料池在超设计基准事故或外部灾害事件(包括自然灾害和人为事件)下的安全性一直是核电厂设计的重点。本工作结合美国核能研究所(NEI)给出的扩大损害的缓解导则(EDMG)提出了针对AP1000外部灾害情形下的SFP缓解策略(包括内部策略和外部策略),并对策略进行了评估。本工作结论有助于AP1000SFP EDMG的建立,对AP1000核电厂的设计、建造、运行管理和事故管理均有很强的参考价值。
After Fukushima nuclear accident,much attention has been paid to the safety of the spent fuel pool（SFP）.AP1000 spent fuel pool cooling system（SPS） is not a safety related system.It is not designed for design basis accident.But the safety of SFP in exterior disaster and severe accident is very important.The extensive damage mitigation guidelines（EDMG） of NEI to AP1000 SFP accident mitigation was studied,including internal strategy and external strategy.The results are useful for design AP1000 nuclear power plant and the mitigation when SFP exterior disaster happens.
