Abstract
As for much industry plants, 40 years passed after construction. The rationalization of the inspection for corrosion under insulation(CUI) of the piping is necessary now. There is much piping in the high place, and a large amount of expenses such as appurtenant work cost. We are promoting the development of the "Low Noise Neutron Moisture Meter Robot" and "Compact X-ray System Robot". This report introduces the development of "Low Noise Neutron Moisture Meter Robot" mainly.
