Abstract: A welded portion inspection apparatus of a reactor pressure vessel moves on an outside surface of the reactor pressure vessel, and is provided with a scan portion having a sensor for detecting a state of the welded portion to be inspected. The apparatus has a first scan axis with a pedestal having the sensor installed for moving the sensor in a predetermined first direction to perform scanning, and a second scan axis orthogonal to the first scan axis for moving the first scan axis in a predetermined second direction. Drive portions are installed removably on both sides of the scan portion for moving the scan portion to a position of the welded portion to be inspected, and a motor is provided for driving the drive portions. The drive portions include a plurality of magnets which are endlessly formed in a line.
