Abstract

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.
- Diverse actuation system,
- Design criterion,
- Defense in depth,
- Safety
