Times Cited Count：1 Percentile：7.67(Engineering, Electrical & Electronic)The paper presents application of a multi-coil eddy current testing (ECT) system to detect defects in steam generator (SG) tubes of Fast Breeder Reactors (FBR). The defects are located near SG tube support plates, while SG tubes were successively immersed in liquid sodium at temperature above 500 degrees and then drain. Three dimensional (3D) Finite Element Method (FEM) numerical simulations, using an in-house developed code, are validated with experimental measurements in both cases of absence/presence of sodium on the outer SG tubes surface.

This study reports applicability evaluations of microwave inspection technique for cracks on inner wall of metal pipes. The experiment is carried out using the straight brass pipe with a diameter of 11.0 mm and the total length of 18.5 m and artificial slits simulating cracks. Experimental result shows significantly large reflections from the slit compared with no flaw, thereby confirming the detectability of this method for cracks in a metal pipes.
