Abstract
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.
