  • the positioning result in the form of the laser measurement and the recording of the camera data showing the laser beams on the edge of the uppermost bentonite ring is recorded for documentation. If one of the laser beams is not visible, the positioning is corrected.
  • the positioning process is saved with the measurement data from the laser sensors and the camera sequences for the documentation. Lowering the in The radiation protection tube container is thus carried out only after precise alignment of the radiation protection tube relative to the bentonite ring, in which the container is to be lowered for the purpose of disposal.
  • the operator it is also possible for the operator to be assisted during a manual drive from a transfer unit to the intended docking station by displaying the positioning and direction of travel as well as navigation instructions on a map of the surroundings by a navigation system.
  • driving instructions for the steering system are to be calculated and made available by the navigation system so that a fully automatic drive is also possible in the transport tunnels.
  • the navigation system should also be used by departing from previously planned routes learned data.
  • the vehicle is driven automatically or manually in the storage tunnel.
  • the required course is defined by reference marks in the ground (transponder).
  • These transponders are located in the middle of the roadway (center line) and can either be sunk or glued on the ground in flat boreholes or glued on the roadway.
  • the positioning of the storage tubes is determined with respect to the transponders and stored with the transponder code in a course card.
  • the vehicle learns how far the center of the storage tube lies next to the center line of the tunnel.
  • deviations of the bearing tubes of +/- 50 mm from the vehicle can be corrected.
  • the positioning of the transponder is measured with two reading antennas at the bottom of the vehicle. Such a method has been proven for driverless transport vehicles, and the positioning of the vehicle can thus be determined to typically about +/- 1 cm.
  • the vehicle has on all sides of laser scanner for the detection of obstacles, and in case of danger of contact with an obstacle or walls, the vehicle is stopped immediately. On the monitor for the Operator is then presented the location of the obstacle with respect to the vehicle.
  • a storage operation of radioactive material containing copper containers can be carried out as follows. As soon as the vehicle has been stopped above the storage well or tube by automatic or manual driving in the storage tunnel, the hydraulic supports on the vehicle are activated and pressed against the roadway. The movement is initially stopped when the vehicle has reached a certain height above the ground. Thereafter, the deviation of the vehicle attitude from the horizontal is detected by sensors. The collected data is used to control the supports so that they are raised or lowered until the vehicle is horizontal. Once the vehicle is oriented horizontally, the cover plate is removed over the bearing tube, using an electromagnet for this purpose.
  • the swing frame is positioned by the body frame in the longitudinal and transverse directions (displacements of +/- 80 mm are possible in any direction), and the radiation protection tube is pivoted into the storage ready position.
  • the positioning is done, as already mentioned, with laser sensors.
  • the process is documented and, before lowering the radiation protection tube, the position is again measured with laser and camera technology.
  • the lifting device is used, which moves horizontally and is fixed and secured vertically above the radiation protection tube (working position).
  • the copper container is received via the docking device and the container coupling device.
  • the lowering of the copper container is also documented.
  • the container coupling device and the docking device are released from the container, so that the lifting device can be moved back to its rest position to release the space so that the radiation protection tube can be moved upwards in the vertical direction and the swing frame pivoted into the transport position can be.
  • the cover plate put back on the storage tube by means of the electromagnet, whereby the actual storage process is terminated.
  • the vehicle is then automatically moved out of the storage tunnel, but this can also be done manually.
