ABSTRACT:
An object of the present invention is to provide an inspection apparatus for inspecting weld zones in a reactor pressure vessel, the inspection apparatus comprising: an ultrasonic probe6for emitting an ultrasonic wave; a probe holding unit60for holding the ultrasonic probe6such that a ultrasonic wave transmitting surface of the ultrasonic probe6is kept in direct contact with or at a constant distance from the outer surface of the reactor pressure vessel1; a pressing unit50for pressing the probe holding unit60parallel to a central axis of a control rod drive housing8against the reactor pressure vessel; and a rotator40for rotating the probe holding unit60and the pressing unit50about the central axis of the control rod drive housing8.
