Detection and Monitoring of Defects in Pressure Vessels
The application of nondestructive evaluation (NDE) techniques to nuclear pressure vessels of nuclear power plant systems has spawned the development of numerous items of remotely-controlled mechanized examination equipment. This equipment is utilized during the initial or preservice examination (PSI) and subsequent in-service examinations (ISI) to meet the American Society of Mechanical Engineers’ (ASME) Boiler and Pressure Vessel Code requirements for these vessels. The following is a discussion of the application of ultrasonic examinations to selected regions of the nuclear pressure boundary of reactor systems for detecting and monitoring defects in these systems.
