Abstract

For the safety enhancement of the nuclear power plant, the safety equipment is constructing additionally under the new regulatory requirements. With the increase of safety equipment, the amount of inspection during the outage may increase. Accordingly, increase of the outage lead to prolong maintenance schedule period. To perform the outage efficiently, we developed health visualization system for the equipment while operations. The health visualization system consists of database, health diagnosis engine and visualization engine. In this health diagnosis engine, the diagnosis technique that integrated a statistical model, which can detect the change of the process value early, with a physical model, which can identify equipment, the parts and phenomenon, was applied. With a constant monitoring of the process value, it is possible to estimate the phenomenon and equipment immediately when the process value shows different behavior than usual. Besides, by understanding that the equipment is healthy while operations, it is possible to optimize the amount of inspected equipment in the outage.
