概要
Abstract: This paper discusses a development of the quantitative method to evaluate the reliability for the maintenance plan with respect to the risk impact both for Core Damage Frequency and Plant Trip Frequency. The quantitative approach includes the considerations for the effect of the Condition Based Maintenance (CBM) changing in addition to the Time Based Maintenance (TBM), and the reliability for the maintenance plan is evaluated using the actual plant-specific maintenance information collected in the plant. In this paper, the developed method to evaluate the reliability for the maintenance plan using the risk information is described. And, the tested evaluation to confirm the effectiveness of this quantitative method is also described. And Furthermore, the necessary condition for the plant-specific maintenance information to use this quantitative method is described.
