Abstract
Pipe wall thinning management in nuclear power plants is aimed at providing a life management process ensuring replacement or repair prior to in-service failure. Ultrasonic testing (UT) and radiographic testing (RT) have been conventional inspection and monitoring techniques for pipe wall management. Recently, interest has grown for advanced inspection and monitoring techniques for characterizing and detecting pipe wall thinning, such as flow accelerated corrosion (FAC), liquid droplet impingement erosion (LDI), flashing erosion, etc, In this lecture, we summarize the current achievement for two upcoming technologies, ultrasonic guided wave testing (UGT) and electromagnetic acoustic transducer (EMAT).
