Abstract

This paper describes a newly developed arrayed multi-coil probe for the testing of steam generator tubes by eddy current testing. Owing to the multi-coil arrangement, it is possible to detect cracks in the whole round of the tube without rotation. Geometry of the probe was decided with the help of numerical simulation, which leads to high detectability of the probe. The signals of this probe were predicted by the edge based finite element method, and comparison between experimental and numerical results showed good agreement. Furthermore, this probe is expected to be convenient to reconstruct the crack shape from its C-scan image.
