Device for inspection and for the carrying-out of possible repair work on the tube bundle of steam generators

Device for the inspection and for the carrying-out of possible repair work on the tube bundle of steam generators, especially for pressurized-water reactors, the steam generators exhibiting a tube bundle fastened to the tube plate for a heat carrier, and the tube plate, together with further housing parts, limiting an inlet and outlet chamber for the heat carrier with a chamber for accepting the device, characterized in that in the housing parts, a tube directed by its bent end towards the tube plate is carried rotatably and longitudinally displaceably and that a tube distributor is coupled to the tube which is adjustable together with the tube in its longitudinal displacement direction and exhibiting guide tubes adapted to the swivelling movement of the tube end, by which the tube end can be brought in its respective axial position successively for inspection of single tubes of the tube bundle, the exits of the guide tubes being directed vertically to the tube plate and being adapted to the tube distribution of the tube plate.
