摘要： A remote inspection device for the inspection of the tubesheet in-bundle region of a steam generator. The device includes a rail system that is easily and quickly mounted to the end of tube at an in-bundle region of a steam generator, a carriage movable on the rail system for feeding at flexible, tape-like wand into the tube, and a probe mounted on an end of the flexible, tape-like wand for performing the inspection operation. The flexible, tape-like wand, which is composed of a flexible metal alloy, has a non-circular center section forming a channel for receiving cabling for the probe and opposed flat, wings on either side of the non-circular center section. Each wing has a row of feed holes positioned remote from the center section that provide engagement with a feed wheel of the carriage.
