This paper reports the reconstruction of a stress corrosion cracking from eddy current signals. The stress corrosion cracking was found in the steam generator tube of a nuclear power plant during ISI period, and its cross-sectional profile is reconstructed with the aid of computer simulation. A crack is modeled as a region with uniform conductivity inside, and the boundary profile and the conductivity of the crack are reconstructed. An inversion algorithm based upon the tabu search is utilized in this study. It is demonstrated in this paper that the profile of stress corrosion cracks can be well estimated from eddy current signals within a reasonable computational time.
