An apparatus that visually inspects a state of sludge and foreign substances found between steam generator bundles positioned at an upper portion of a tube sheet of a steam generator of a nuclear power plant using a visual inspector mounted in a robot moving on an inner wall surface of the steam generator for removing the foreign substances.

Apparatus for visually inspecting and removing foreign substance from gap of heat tube bundle in upper part of tube sheet of second side of steam generator

An arc-shaped flexible printed circuit film-type endoscope using an imaging device with driving holes. The endoscope has an image photographing device and an object insertion device and further includes a plurality of driving holes which are formed at regular intervals in a longitudinal direction of the object insertion device, and a driving device which rotates while being sequentially inserted into the driving holes, thus moving the object insertion device. The endoscope controls movement into a small space, makes it easy to inspect a narrow heat transfer tube or gaps formed between heat transfer tubes, achieves high economic efficiency, increases the reliability of endoscopy, and increases life-span.

Arc-shaped flexible printed circuit film type endoscope using imaging device with driving holes

Disclosed herein is an arc-shaped flexible printed circuit film type endoscope using an imaging device. The endoscope includes an image photographing means and an object insertion means. The image photographing means includes a head housing to which an imaging device and an illumination means are mounted, and functions to photograph an image. The object insertion means includes an arc-shaped flexible thin foil, an insulating adhesive film, a circuit film and an insulating protective film which are layered and inserted into an interior of an object to be inspected. The object insertion means is connected at one end thereof to the image photographing means and connected at the other end to a transmission cable via a connector.
