摘要： An inspection apparatus is suspended from a robotic positioning arm and is operable to inspect the surface of a boiling water reactor core shroud. The apparatus includes an attachment bracket connected to the robotic positioning arm. A guide is connected to the attachment bracket and receives an arcuate rail having a first end portion and an opposite second end portion. A motor assembly drives the rail within the guide to position the rail at a desired location along the core shroud surface relating to the guide. The rail carries a transducer assembly which is moved along the rail by a chain and sprocket assembly. As the motor assembly drives the rail, the chain and sprocket assembly simultaneously moves the transducer assembly along the rail to inspect the core shroud surface.
