METHOD FOR PREDICTION OF CORROSION RATE OF HEAT TRANSFER TUBE BY USE OF EDDY CURRENT TEST METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of predicting a corrosion rate of a heat transfer tube using an eddy current test method.SOLUTION: A method of predicting a corrosion rate of a heat transfer tube using an eddy current test method comprises: a process (process 1) of performing an eddy current MRPC probe inspection of a heat transfer material; a process (process 2) of evaluating a MRPC probe inspection signal generated in the process 1; and a process (process 3) of predicting a corrosion rate of the heat transfer tube material from a noise value in the MRPC inspection signal of the heat transfer tube evaluated in the process 2. When the method of predicting the corrosion rate of the heat transfer tube according to the present invention is used, criteria on the corrosion rate of the heat transfer tube can be established as requirements for a corrosion rate of the heat transfer tube in a primary system condition through an eddy current MRPC noise inspection of the heat transfer material, so that there is an effect that a heat transfer tube material having a low corrosion rate can be selected in a material selection process.SELECTED DRAWING: Figure 6
