A magnetic flux leakage (MFL) method must be an effective nondestructive evaluation (NDE) technique for the wall thinning in nuclear power plant, because this method has already been applied to industry field such as gas pipeline. A development of a probe feasible for piping and a feasibility study of MFL method for application in reinforcing plate in nuclear power plant are required for practical uses. Therefore, ancillary yokes are examined to adapt to the piping shape, and higher sensitivity was achieved to estimate depth in slit on piping. Additionally, steels superposed were prepared and a slit modeled wall thinning was formed on underlayer here, then, applicability of MFL method on the superposed specimen was investigated.
