Abstract: A guidance system (16) for a camera is introduced into the evaporator section of the steam generator through an inspection port (14) in the external shell and tube bundle wrapper and is passed up through the openings in the horizontal support plates of the tube bundle. The camera is then guided into place at the level of the horizontal support plate (8) and is moved across the plate between the tubes of the tube bundle. The guidance system consists of a flexible strip (17) with a guide (18) supported on a rail (19).
