The application of DCS （Digit Control System） is a certain trend for the development of nuclear power. DCS not only improves the control capability of nuclear power system, but also increases the com- plexity of the system. Traditional safety analysis techniques based on event-chain model are facing challen- ges. In order to improve the safety performance of nuclear power DCS, the latest research achievement in the field of safety engineering should be focused, studied and applied into nuclear power safety. This paper introduces a new safety ...
