ABSTRACT:
A method for dismantling bulky parts of pressure-vessel fittings of a nuclear plant and for receiving the dismantled parts presents difficulties with regard to radiation-proof handling. In order to solve that problem, a dismantling container which is set down in a water tank is used. The fittings to be dismantled are introduced into the dismantling container. Furthermore, a receiving container for the dismantled parts is inserted into the dismantling container. A dismantling manipulator is supported on the flange of the dismantling container. When the receiving container is full, the dismantling manipulator is moved to the side, the receiving container is extracted and its contents are transferred to a transport container.
