Demonstration of reliability-centered maintenance

On March 9, 1988 the Southern California Edison Company was selected by the Electric Power Research Institute as one of two utilities to perform a large scale Reliability-Centered Maintenance demonstration project to be co-funded by EPRI and SCE. The overall objective of this project is to demonstrate that RCM can be effectively performed in a plant environment leading to improved overall unit performance. The objective of SCE is to optimize the existing Preventive Maintenance program at San Onofre Nuclear Generating Station Unit 2. The successful achievement of this goal requires the active involvement and the cooperative efforts of the operations and Maintenance Support, Maintenance, Station Technical, and Operations Divisions. This report describes progress to date in the RCM core elements such as system selection, applications of the RCM methodology to the systems selected, lessons learned, course corrections, implementation of the RCM recommendations, results achieved, and development of a living program. The overall project involves analysis of approximately twelve to sixteen systems. To date, six have been completed and two are underway. The results to date indicate a significant payback in maintenance cost reduction, even with the expansion of some PM activities for identified critical failure modes. 7 refs., 12 figs., 7 tabs
