摘要： A reactor head inspection system (13) for use in performing a non-destructive inspection of tubular components (5) mounted on an interior surface of a reactor head (3) is disclosed. The inspection system includes a movable carriage assembly (12) including an elevation arm (18) and an inspection device (13) mounted at a distal end of the elevation arm. The inspection device (13) includes a C- or U-shaped collar (20) having an interior surface of sufficient interior dimension to enable positioning of the interior surface of the collar in close proximity of an exterior surface of a tubular component (5) and also includes a magnetic and/or eddy current sensor (41). A plurality of video cameras (35) and light sources (50) are also provided on a distal surface of the collar (20) such that, when mounted on the elevation arm, the collar (20) can be controllably positioned in close proximity adjacent a tubular component (5) of the reactor head to achieve a 360° view and inspection of a surface of the tubular component (5).

摘要： A remote inspection device (1) for the inspection of the tubesheet in-bundle region of a steam generator. The device includes a rail system (9) that is easily and quickly mounted to the end of tube at an in-bundle region of a steam generator, a carriage (10) movable on the rail system (9) for feeding at flexible, tape-like wand (3) into the tube, and a probe (11) mounted on an end of the flexible, tape-like wand (3) for performing the inspection operation. The flexible, tape-like wand (3), which is composed of a flexible metal alloy, has a non-circular center section forming a channel (12) for receiving cabling for the probe (11) and opposed flat, wings (22) on either side of the non-circular center section. Each wing (22) has a row of feed holes (20) positioned remote from the center section that provide engagement with a feed wheel (21) of the carriage.
