Nuclear Power Plant Aging Research CenterNon-Destructive Inspection and Monitoring Group
Working Toward a Certain Diagnosis of Degradation
Development of non-destructive testing techniques or metal materials
Development of techniques for diagnosing, status-monitoring and life-prediction for equipment in nuclear power plants
The Group has been committed to development of engineering techniques for better safety in nuclear power plants: the objectives of development include insulation degradation diagnosis for power cables, monitoring of motor bearings and life prediction for rubber O-rings and diaphragms.
Automatic ultrasonic flaw detection device has been developed using a large aperture twin crystal transducer; this device boasts greater ability to detect defects in the welds within the primary coolant piping. Applicability of this device has been reviewed on the site
Cable aging diagnosis technique whose usefulness has been ascertained in Japan’s state-sponsored research project
