摘要
共因故障是进行核电站保护系统设计时需重点关注的风险。为了使保护系统设计能避免共因故障的发生或减轻共因故障的后果,分析了共因故障的产生原因,并对国际法规、标准的相关要求进行了研究,总结出为应对共因故障所应遵循的设计准则。最后,设计了可防止共因故障的典型反应堆保护系统架构。该保护系统架构所采用的纵深防御和多样性设计手段可作为今后核电站保护系统设计的参考。
Common cause failure （CCF） is the risk to be paid great attention during designing the protection system for nuclear power plants （NPP）. To avoid the occurrence of CCF or relieving the consequence caused by CCF, the causes resulting in CCF are analyzed, the related requirements of international laws and standards are researched, and the design criteria should be followed to prevent CCF are summarized. Finally, the architecture of the typical reactor protection system to against CCF is designed. The measures of defense-in-depth and diversity adopted in this architecture will be the reference for designing NPP protection systems in future.
