Abstract:
A nuclear power plant construction preparation unit includes: a device main body which enters into a space; a moving part which causes the device main body to enter into the space; an eddy-current inspection sensor which is provided on the device main body, and which detects a target portion of a member surface within the space; a punch marking part which is provided on the device main body, and which performs marking on the member surface; and a control part which controls the moving part and the marking device based on detection results from the target portion detection device, to thereby perform marking at a relative position with respect to the target portion.
