摘要
Abstract
Digital instrument and control(DI&C)technology has gradually applied in nuclear power plant(NPP),the common cause failure(CCF)due to improper design and/or use may affect the safety of NPP.Therefore,relevant guidelines at home and abroad have put forward the requirements for DI&C system defense-in-depth and diversity(D3).The consequences of all accidents of chapter 15 of the safety analysis report(SAR)concurrent with the CCF of safety level DI&C system shall be acceptable.CAP1400 is equipped with a Diverse Actuation System(DAS),which includes 6 automatic actuations and 10 manual actuations.The diversity of DAS is of sufficient quality based on qualitative and quantitative evaluations.The methodology of D3 analysis for CAP1400 is established,all accidents are calculated,the results demonstrate that the capability of CAP1400 DAS is enough to mitigate all accidents concurrent with the CCF of safety level DI&C system.关键词
