Definitions

  • the present invention relates to a repository according to the preamble of claim 1.
  • the invention is generally concerned with the provision of a repository for storage in a geological formation, especially in deep holes in rock salt.
  • molds that are filled with highly radioactive waste should be stored.
  • the repository package should be able to be integrated into existing and proven devices with known gripping contours and known glass mold bearings.
  • the repository container should enable the construction of a very simple and inexpensive transport packaging for its transport and should correspond to the storage conditions in terms of weight.
  • the present invention now proposes the features that are specified in the characterizing part of claim 1 and as an advantageous further development in the characterizing part of the subclaims.
  • the particular advantage of the repository container according to the invention is that the rock pressure load can be absorbed by the repository container by using a composite construction with a high-strength inner tube, the necessary corrosion protection being guaranteed by the shrinking of an unalloyed steel onto the high-strength inner tube.
  • the invention thus enables the production of an inexpensive final storage container from simple bulk materials and semi-finished products with minimal mechanical post-processing.
  • the low weight of the repository package enables safe disposal in deep geological formations in boreholes. This ensures optimal utilization of a deep rock salt formation. Interface problems with existing or planned facilities such as gripper contours or the handling and storage in known glass mold stores are avoided by the design according to the invention.
  • the self-shielding effect of the lid and bottom plug enables the construction of a very simple and inexpensive type B transport packaging with a slight increase in the weight of the final storage container.
  • the thickened cover stopper safely reduces the dose burden on the operating personnel due to scattered radiation when the final storage container is abseiled into an emptying hole. Additional shielding can thus be largely eliminated.
  • the mold 1 is shown with the highly radioactive content, which can consist of glazed fission products from the reprocessing of spent fuel elements from nuclear reactors or from spent fuel elements themselves.
  • the mold 1 has the known mushroom head 2 on its upper side for gripping. It is introduced into the actual longitudinal cylindrical storage container 3, the tubular wall 4 of which is composed of the two layers or tubes 5 and 6.
  • the outer tube 5 is relatively thin-walled compared to the cover and bottom plugs 9, 10, ie with little shielding effect against above the radiation from the mold 1.
  • the plugs 9 and 10 consist of normal structural steel, the corrosion rates of which are known under final storage conditions and the corrosion behavior of which can therefore be calculated.
  • the inner tube 6 is now inserted tightly, e.g. shrunk in or connected by means of narrow gap welding.
  • the inner tube 6 sits non-positively between the stopper and thus forms a continuous, wall 4 reinforcing support connection between the cover stopper 9 and the bottom stopper 10. Since the inner tube 6 is made of high-strength material, preferably tool steel, the axial load-bearing capacity of the repository container 3 is despite low wall thickness and calculable corrosion rate of the relatively soft material for the outer tube 5 increased considerably. This also increases the number of repository containers 3 that can be stacked in a borehole for strength reasons.
  • a particularly favorable transport packaging for the final storage container 3 is formed by the thick-walled transport tube 13, which has a shielding effect and in which the container 3 is inserted.
  • the container 3 is locked in the transport tube 13 by means of the securing bolts 14 and 15, which can be inserted radially or tangentially and can be released again for unloading.
  • the end openings 16 and 17 of the tube 13 are closed by means of the end pieces 18 and 19, which in turn act as shock absorbers in the case of a container and which can also have an additional shielding effect.
  • the end pieces 18 and 19 can have a larger outer diameter than the transport tube 13.
