Definitions

  • the invention relates to a system for transferring objects from a contaminated space into a container which is docked to the transfer system in a contamination-free space.
  • the invention has for its object to provide a system which allows the transfer of objects of different shapes and / or sizes when used economically.
  • a ventilation partition wall which consists of a round disk which can be moved around its center and which is provided on a circular line concentric with its center with a plurality of openings with different cross sections.
  • the invention provides a system with which objects of different shapes and / or sizes can be transferred with only one transfer line, and which has no sealing difficulties whatsoever.
  • the ventilation partition 1 designates a vertical ventilation partition which divides a work area into two separate rooms 2 and 3 which are separated from one another in terms of ventilation.
  • the room 2 is exposed to an open radioactive load, ie contaminated, since there are broken down spent fuel elements, which, for. B. as fuel bundle or as pressed square fuel assembly structural parts, so-called compacts, outsourced.
  • Room 3 is free of contamination; it serves for loading containers 4 to be disposed of with the radioactive objects 5 to be removed.
  • the ventilation partition 1 has an opening in front of which there is an insert 6 which is provided with two openings 7 and 8 with different cross sections.
  • the opening 7 has a square cross section and serves for the passage of compacts.
  • the opening 8 has a cross section in the form of a trapezoid arched on one side and serves for the passage of fuel bundles.
  • the cross sections of the openings 7 and 8 are worked out exactly according to the dimensions of the containers 4 to be disposed of.
  • the openings 7 and 8 widen to an area which serves to receive an inflatable sealing ring 9.
  • the insert 6 consists of a round disk in which the openings 7 and 8 are located on a circular line concentric with the center of the disk.
  • the disk-shaped insert 6 carries on its periphery a ring gear 10 which meshes with a gear 11 which can be rotated by a drive 12 fastened to the ventilation partition 1.
  • the insert 6 is fastened to the ventilation partition 1 via a ball slewing ring 13.
  • the ball slewing ring 13 is sealed off from the space 3 by a sealing ring 14.
  • the sealing ring 14 can be exchanged remotely and is fastened to the ventilation partition wall 1 with an extension 15 by screw members 16.
  • the openings 7 and 8 are closed by sealing swiveling hoods 17 when not in use.
  • the hood cover is opened remotely to use this opening and then also the closure of the container 4, after this to the insert 6 via the seal 9 was docked.
