In order to improve safety of major equipments in nuclear power plants, an advanced FMEA (Failure Mode and Effect Analysis) was developed which was integrated PFM (probabilistic fracture mechanics) into the proven FMEA by evaluating the risk priority number in maintenance management based on a trio of anomaly occurrences in equipments (O), their severity (S) and their detectability (D). The results of equipement risk evaluation were visualized by evaluating the triangle area in the radar chart of three para...

The five post-irradiation examination facilities in JAEA's Oarai research and development institute have been operated for over 40 years in order to investigate the irradiation performance of fast reactor fuel materials. The equipment associated with these facilities has been managed to maintain secure from the problems occurred in the process of aging. Therefore, we established a safety assessment method for aging facilities in 2002, and we have been conducting maintenance management of facilities since th...
