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 for identifying a measured value of a velocity or speed of an object where a measured value call-in can occur at any time. A chronological spacing of measuring pulses of a speed sensor is measured and a measured value is formed therefrom. The measurement is carried out until either a measured value call-in occurs, a maximum number of measuring pulses is registered, or a maximum measuring duration is exceeded. When no measuring pulse or only one measuring pulse is registered, a distinction is made in the formation of the measured value as to whether a measuring duration corresponding to a minimum velocity or minimum speed is upwardly or downwardly crossed. An initial counter reading is stored at every measuring start and at every first registered measured pulse. A final counter reading is stored at every further registered measuring pulse until either a measured value call-in occurs or the maximum measuring duration is exceeded. The time interval lying between the initial counter reading and the final counter reading forms the basis for the calculation of the measured value.

A gripping tool for a device for the remote-controlled removal of samples in housings with heads from a container includes a mast having a first coupling part. A second coupling part is opposite and associated with the first coupling part. A guide bar elastically bears on the second coupling part in a telescoping manner with pivots disposed on the guide bar. At least two catches of a two-armed lever are disposed on the pivots and have guide grooves formed therein. A bushing surrounding the guide bar has guide pins each engaging a respective one of the guide grooves. At least one remotely controlled linear drive moves the bushing in the direction of the longitudinal axis of the bushing for surrounding the head of the sample housing with the catches like tongs.
