Preventive Maintenance Optimization based on Historical Data
Nuclear power plants (NPPs) follow an established maintenance plan to ensure safe and reliable plant operation. These established maintenance plans are part of a preventive maintenance (PM) strategy and are defined for all equipment and systems at a plant site. For the time-based PM tasks, workers from electrical, mechanical, and instrumentation and controls maintenance perform different activities, like inspection, calibration, replacement, and refurbishment, at a defined interval, usually without taking into consideration the condition of the equipment and system. Due to the high cost and labor-intensive nature of the PM strategy, it is important to optimize these intervals through PM Optimization (PMO). In this presentation, we will use historic data for a motor-driven pump is used to evaluate any change in the risk of failure of a system or component if these PM interval are revised. The presentation will also discuss potential cost savings with the recommended change in interval and minimal to no risk of failure of the system.
