Abstract

Maintenance optimization process in nuclear power plants (NPPs) has, in recent decades, been driving the transition of maintenance strategies from time-based preventive maintenance to systematic strategies depending on both equipment condition and reliability analysis. Starting with a comparison of various types of maintenance strategies in current NPPs, this chapter highlights the evident advantages of condition-based maintenance (CBM) in both technical feasibility and cost-effectiveness. This chapter also expounds the theoretical foundation and application methodology of CBM, as well as the complementary relationship between CBM and RCM. Taking Daya Bay nuclear power base as a case example, we introduce in detail the experience of using Reliability-centered Maintenance (RCM) and CBM to drive maintenance improvement in NPPs, which serves as a cornerstone for the application of RCM analysis-based CBM maintenance in other plants.
