Ultrasonic Inspection of Steam Generator Tubing by Cylindrical Guided Waves
In this paper we report on the experimental results demonstrating the potential of using cylindrical guided waves (CGW) for inspection of steam generator tubing (SGT). The CGW ultrasonic technique is intended to complement the present eddy current (EC) practice for in-service inspection as well as to provide an alternative tool for pre-service inspection. Below, we review the current NDE practice for SGT and the motivation of this study.
