A number of PSA (Probabilistic Safety Assessment) studies have been applied to the optimization of maintenance activities in nuclear power plans from a viewpoint of safety focusing on the risks of core meltdown. However, even a small-scale incident of component, which never causes the core meltdown, resulted in the reactor shutdown and economic losses. The economic losses due to this kind of incident become enormous when including the losses that are not officially counted. Accordingly, in addition to the safety analysis focusing on the risk of core meltdown, it is very useful to establish a model that can plan maintenance...
