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).

Abstract: An electrolyte is circulated between the surface to be machined, charged to an anodic potential, and a working electrode (9') charged to a cathodic potential. The electrolyte contains lithium nitrate as sole active element at a concentration of between 20 g/l and 2350 g/l and preferably between 50 g/l and 250 g/l. The method can be applied to machining the surface of any metallic part and especially to machining the inner surface of tubular parts (5) such as nuclear reactor vessel bottom head or head penetrations; in this case, the electrochemical machine cell consists of a cylindrical working electrode (9') placed inside the part to be machined.
