Abstract
An inspection device for the upper internals of a nuclear reactor comprising an elongated probe body which is lowered through a central aperture in a support plate that forms part of the upper internals and includes a plurality of vertically extending control rod apertures. Radial channels extend outwardly from the central aperture, each communicating with corresponding control rod apertures. A radially moveable transducer is mounted to the probe body and the latter is rotatable to a position for accessing each channel for radially moving the transducer into the channel. The transducer detects the profile of the channel. An area of particular interest is the area of communication between the channels and the control rod apertures. This area is susceptible to wear due to vibrations of the control rods.
