Reliability Assessment for Steam Generator Water Level Control System in NPP Based on BDMP
摘要
Abstract
Digital instrumentation and control system (DICS) has been widely applied to safety/non-safety systems in NPP .As the central nervous system ,its reliability is cru-cial to the operation and maintenances in the process of operation .Based on the struc-tural and control logics of the digital steam generator water level control system (SGWLCS) ,the Boolean logic driven Markov process (BDMP) formalism was recom-mended and applied to the assessment of the system .With the increase of simulation steps ,the cumulative distribution probability (CDP ) of repairable and non-repairable SGWLCS was calculated .The BDMP model was constructed by KB3 ,and the produc-tivity analysis was performed by the Monte Carlo simulation software YAMS . The tendency of the system CDP used to derive the failure probability with the performance period was assessed in quantitative way .Through the sensitivity of each component of the system ,the importance to the whole system of each component can be intuitively achieved .关键词
