An apparatus for dismantling a radioactively contaminated tubular installation part which is located under water contains a base part which can be fixed to the installation part and in which a rolling cutting apparatus is mounted. The rolling cutting apparatus can be positioned in or on the installation part and has at least one cutting roller which can be moved to the inner or outer surface of the installation part and can be moved along it. The apparatus can be used to dismantle and remove even installation parts to which access is difficult, for example the cyclones which are installed in the water/steam separator of a boiling water reactor.

A method and an apparatus introduce a self-propelled in-pipe manipulator into the interior of a pipeline. A hollow body receives the in-pipe manipulator, is open at least at one end surface and is positioned at an opening of the pipeline, from where the in-pipe manipulator can drive on its own into the pipeline.

A core barrel for a reactor pressure vessel of a nuclear reactor plant has a carrying structure that is supported on an inner surface of the shroud of the barrel. The carrying structure receives a tension rod that extends parallel to the longitudinal axis of the barrel and braces the shroud in the axial direction.
