Managing the aging of critical components within a nuclear power plant is a challenging task that ultimately determines the value and revenue generation of the plant. This paper will provide an overview of a process for determining the critical components of the power plant and describe a long term equipment reliability and aging management program for these components. This program determines the potential failure modes and rates for each critical component part and identifies the effective repair, replacement, inspection, diagnostic, and maintenance activities. It also describes a tool for determining the optimal timing of these activities to produce the most value for the power plant. This program is currently being implemented at several power plants. As nuclear plants strive to reduce costs, extend life and maximize revenue, the aging management program and the supporting tools summarized in this paper can enable development of a long term, cost efficient plan to manage the aging of the plant’s critical components and systems.
