Abstract:

Safety, reliability and maintenance are key issues in the operation of nuclear power plants. Proper and organized implementation of maintenance activities can provide a platform for the safe operation of the power plant.In This research we try to increase the reliability of power plant systems and equipment by optimizing maintenance activities by introducing the reliability-based maintenance method (RCM).In This article the different approaches in the RCM program implemented in nuclear power plants and tries to choose an operational and efficient method in Bushehr nuclear power plant. Hence, the conflicts between classical RCM and simple RCM have been raised and an attempt has been made to resolve these conflicts through a comprehensive model.In this paper, two different RCM methods based on engineering judgment and statistical analysis have been used and the effect of these methods on heart rate has been evaluated. The method of combining FTA and recursive FMEA to evaluate equipment and select critical equipment according to the depth of analysis Optimally, used. In this method, by performing FTA and FMEA repeatedly at different levels of power plant analysis, critical equipment is identified using probabilistic safety assessment criteria
