Condition-based maintenanceShika Nuclear Power Station
概要
In the Nuclear Power Station, maintenance of many equipment are performed by time-based maintenance which overhaul the equipment at the reactor outages intervals. However, there is a tendency that has become an excessive maintenance such as inspection interval is short in time-based maintenance, on the contrary there is a risk that shorten the life of the equipment is concerned. Therefore, it is promoting the introduction of condition-based maintenance to implement maintenance at the appropriate timing based on the operation state of the equipment. In Shika Nuclear Power Station, the vibration, lubricants and Infrared thermography diagnosis data are collected for implementing a condition-based maintenance. In this paper, we introduce efforts of condition-based maintenance and diagnostic case of equipment.
