Description

The differential encircling coil-type probe and the unirradiated standard fuel rod were fabricated. In order to investigate defects of irradiated fuel rods by eddy current examination, The correlation among the frequency, the phase and amplitude of the eddy current signal was derived by analyzing the resistance and the reactance components. The maximum amplitude of the eddy current signal was shown at an optimum frequency of 400 kHz. Therefore it is possible to distinguish such defect shapes as external, internal and through-hole defects. The results of the eddy current examination coincide with that of the nondestructive metallographic examination. Also, the ridge of the fuel rod was analyzed by eddy current examination
