摘　　要：研究了ACP100模块式小堆的全厂断电(SBO)事故应对策略,分析了非能动余热排出系统、非能动堆芯冷却系统对于SBO事故的缓解作用。研究结果表明,ACP100具有多种不依赖于可靠电源应对SBO事故的策略,ACP100采用非能动余热排出系统或非能动堆芯冷却系统均可以保障SBO事故下的堆芯余热长期导出,长期维持反应堆的可冷却性。The ability of nuclear power plants to deal with Station Blackout(SBO)accident has attracted much attention after Fukushima accident.Whether there is a sufficient ability to mitigate SBO accident has become crucial to measure the safety performance of a nuclear power plant.As a new type of reactor,small modular reactor requires higher safety performance.The mitigating effect of passive residual heat removal system and passive core cooling system for SBO accident of ACP100 is studied in this paper.The results indicate that ACP100 is with multiple strategies to deal with SBO accident that rely little on reliable power supply.Long-term residual heat removal and resultant long-term coolability can be ensured for ACP100 by the residual heat removal system or passive core cooling system.
