| Research Abstract |
In the nuclear power plant, the careful inspection is carried out about primary cooling system tubes in the reactor core, and the structure near the reactor core. However, as for the steel tubes of the secondary system that does not contain a radioactive material, inspection is made scanty. In this research, the monitoring inspection method for the opposite side defect of steel tubes in the secondary system is examined using the DC and AC magnetic field.
