Abstract
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. When the prediction method of a corrosion rate of a steam generator tube according to the present invention is used, the steam generator tube material which has low corrosion rate can be selected at the material selecting step because the corrosion rate can be predicted and the criterions on the corrosion rate of the steam generator tube can be established as the requirements through an eddy current MRPC noise inspection of the steam generator tube material.
