Application of RCM analysis based predictive maintenance in nuclear power plants

Maintenance optimization process in nuclear power plants (NPPs) has been driving the transition of maintenance strategies from time based preventive maintenance (PM) to systematic strategies depending on both equipment condition and reliability analysis in recent decades. Start with comparison of different types of maintenance strategies in currents NPPs, this paper pointed out that predictive maintenance (PdM) usually has evident advantages in both technical feasibility and cost-effectiveness, and expatiated the theoretical foundation and application methodology of PdM. Taking Daya Bay nuclear power base for example, this paper introduced in detail the applications and experience conclusion of Reliability-centered Maintenance (RCM) analysis based PdM management in NPPs, and presented the latest progress of researches and developments of PdM in Chinese nuclear power field.
