Abstract

See full text

Disclosed herein is a method including: performing eddy current testing on a steam generator tube material by using a motorized rotating pancake coil (MRPC) probe, evaluating a test signal measured using the eddy current testing, and predicting the corrosion rate of the steam generator tube material from a noise value in the MRPC inspection signal of the steam generator tube obtained from the evaluating.
