Abstract

Detection of corrosion and build up of corrosion products, such as magnetite, in CANDU® Steam Generators (SGs) at tube supports is critical for monitoring of SG condition. A Pulsed Eddy Current (PEC) probe has been developed to enhance SG inspection at support structures. The PEC probe demonstrated capability to detect magnetite at simulated broach support structures. Results were used to validate Finite Element Method (FEM) modeling of PEC signal response to magnetite. The validated FEM model can be used to further explore effects of magnetite on PEC probe responses.
