Abstract
Digital systems have replaced analog because they can help increase plant safety and reliability. Conventional event-tree (ET)/fault-tree (FT) method have been used for reliability analysis of digital systems in nuclear power plants (NPPs). The static ET/FT approach does account the dynamic interaction between the digital system and the NPP process systems. Among the PSA analyst and regulatory body, there is limited consensus on the use of dynamic models for estimating risk from NPP. In this work, cell-to-cell mapping technique (CCMT) along with Markov model is used to estimate time-dependent reliability of water tank-level control problem. The Markov model is developed for inlet and outlet control valves, while the CCMT equations are solved with predefined time steps. These two are coupled to get the time-dependent probability of top event.
