【摘要】 基于福清核电厂仪表控制系统纵深防御和多样性的现状,阐述了设计多样化保护系统(DAS)的设计流程、设计准则、系统结构和设计要点。福清核电厂1、2号机组事故分析的结果表明,通过设置DAS,缓解了数字化安全级仪表控制系统发生软件共因故障(SWCCF)的后果,提高了核电厂的安全性,是一个应对数字化安全级仪表控制系统发生SWCCF的行之有效的解决方案。更多还原

【Abstract】 This paper analyzes the current condition of defense in depth and diversity for Fujian Fuqing nuclear power plant, and illustrates the design flow, design criterion, system structure and the design point. The result of accident analysis for Fuqing nuclear power plant unit 1 and 2 indicates that DAS is capable of mitigating the result of SWCCF in digital safety instrumentation and control system and improving the safety of the nuclear power plant, and it is an effective method to cope with SWCCF in digital safety instrumentation and control system.更多还原
