Eddy-Current Tomographic Inversion Mathematical Tools for Non-Destructive Evaluation of Boiling Tubes [link]Paper  abstract   bibtex   
Mechanical stress and corrosion modes represent the main contributors to the degradation and fatigues of the steam gen- erator (SG) tubing in nuclear power plants. The large variety of the degradation types challenges the integrity and hence the safety of the boiling tubes (BT) in the SG. The station reliability remains highly sensitively dependent on the repairs and replacement in the maintenance phase, which has recorded an extensive activity worldwide in nuclear power plants sites and stations. Novel technology tools beneficent from new Mathematically developed algorithms play a key role in the inspection and monitoring of tubes. This work aims at devel- oping new efficient yet simple tool based on inverse problem imaging to help in the Non-Destructive Evaluation (NDE) of the BT. Our technique uses the Eddy-current excitation to im- age the depositions of magnetite or possible cracks through the newly developed Linear Sampling Method (LSM) [1], which we couple with the variational based shape optimiza- tion technique [2,3] to enhance the quality of the tomography of depositions.
