Southern California Edison Company (SCE) has completed a two year demonstration of Reliability Centered Maintenance (RCM) at San Onofre Nuclear Generating Station (SONGS) Unit 2. The demonstration involved the application of detailed RCM analysis to 12 plant systems and the implementation of the preventive maintenance (PM) and testing recommendations from these analyses. Other tasks in support of the successful application and implementation included (1) the selection and prioritization of systems for RCM analysis, (2) employing RCM as the technical basis for technical specification change, and (3) development of an RCM living program. The overall objective of the project is to demonstrate that RCM can be cost-effectively performed in a nuclear plant environment. This report describes in detail the methodologies which evolved at SONGS to perform the above tasks. This report summarizes the recommendations from the analyses which include task deletions, task additions, task modifications, and design changes. A significant portion of these recommendations have been evaluated at SONGS, and the status of task implementation is described herein. Significant maintenance man-hour savings are documented on systems for which the recommendations have been evaluated and implemented. Insights of value for future RCM applications are enumerated. Finally, plans for continued use of RCM at SONGS are confirmed and described. 12 refs., 17 figs., 2 tabs.
