Spectral Reconstruction of Magnetite Deposits in Steam Generator Tubing: An Artificial Intelligence Approach [link]Paper  abstract   bibtex   
Steam Generator (SG) tubing is a crucial component in the Pressurized Water Reactors. A variety of degradation of the SG tubes challenge the integrity of such component and therefore the station reliability and even safety. Cracks, hardening, stress corrosion are serious factors that threaten tube failure, hence the safety of the power plant. To prevent unwelcome radioactive accident, Non-Destructive Evaluation (NDE) techniques are heavily used, among which tomography by Eddy-Current (EC) excitation. The latter is considered to be among the cheapest NDE techniques. In this work we shall present a tomography inversion technique based on the use of Artificial Intelligence (AI) together with Finite element solution [1] to Eddy-current problem. A variety of inversion technique have emerged, [2,3,4,5,6] and recently [7] without being exhaustive. These techniques suffers from large memory demand, and ill-posedness in the sense of dependency of the output with respect to the initial guess. The latter method [7] constitute a way around large memory requirement, although it produces indicator function that is diffused hence not a clear cut toward detecting the deposition. Nonetheless, the quality- cost ratio for the LSM makes it highly potentially good method to approximately detect conductive deposition and cracks. In this work we aim at introducing AI technique as an alternative approach for the NDE.
