Abstract
In order to locate a defective tube in a U-tube bundle of a steam generator so arranged that the tube ends are fixed in a tube plate which defines an internal space with the bottom end-wall of the steam generator shell, the entire tube plate is swept by at least one camera placed within the internal space and is visualized on a display screen placed externally of the steam generator. A luminous mark having an identification function is projected independently onto the tube plate at the point corresponding to the extremity of a defective tube and is displayed on the screen during the sweeping operation.
