Abstract
With the extensive application of digital control system (DCS) in Chinese nuclear power plant, the safety of DCS attracts people’s attention. First of all, this paper briefly introduces the overall structure of DCS. Then it summarizes the several key issues about DCS from the perspective of nuclear safety review: the single failure criterion, testability, diversity, software verification and validation (V&V), configuration management, which are common issues in the safety review. These issues are analyzed according to the relevant regulation and standards. At last, some solutions are given to these common issues, and some suggestions are made for future review.
