Abstract

This paper is concerned with a shape recovery of natural cracks in steam generator tubes of the PWR nuclear power plant. A three dimensional forward model is developed for analyzing accurate probe response evaluation in eddy current testing. Using the evolutionary programming, an efficient inverse scheme is proposed for recovering natural cracks. The proposed algorithm is tested for stress corrosion cracks of the steam generator tube samples.
