Definitions

  • the present invention relates to a transport and / or storage container for heat-producing radioactive materials, consisting of a base body and a gas-tight jacket made of corrosion-resistant material which surrounds this base body at a distance on all sides.
  • radioactive materials e.g. spent fuel elements from nuclear power plants or waste from plants for the reprocessing of spent fuel elements
  • containers are used in which the radioactive materials are safely enclosed, from which the heat generated can be safely removed at any time and which are critically safe.
  • Thick-walled containers are usually used, some of which are lined with stainless steel on the inside. Should they Containers are stored underground, e.g. in disused mines, the container walls must be able to absorb the mechanical forces and be corrosion-resistant.
  • a heat-resistant, inexpensive material is used for the base body, which does not have to be corrosion-resistant, since it does not come into contact with corrosive media.
  • the tank is dimensioned so that it can withstand the rock pressure. It does not have to be tight so that the bottom and the lid can be inserted or screwed in.
  • the materials for the base body are e.g. suitable heat-resistant fine grain steels in question.
  • suitable heat-resistant fine grain steels in question.
  • concrete containers can also be used as the base body.
  • Corrosion-resistant materials are used for the outer layer or the outer jacket of the containers.
  • high-alloy steels such as Hastelloy, or zirconium or titanium-based steels.
  • the thickness of these plates is chosen so that it resists the expected corrosion for the duration of storage, and since the "base body is not gas-tight, to withstand the internal pressure. This internal pressure builds up after the loading of the container due to heating by the heat-producing radioactive inventory.
  • the maximum internal pressure that builds up is decisive for the design of the thickness of the outer jacket, i.e. Because of the internal pressure, the corrosion protection jacket must be dimensioned considerably thicker than would be necessary in and of itself for reasons of corrosion protection and tightness. This applies in particular to flat floors and lids, which have to be disproportionately thicker than the cylindrical shells of other usual transport and storage containers given the dimensions to be considered.
  • the invention was therefore based on the object to provide a transport and / or storage container for heat-producing radioactive materials, consisting of a base body and a gas-tight jacket which surrounds this base body at a distance on all sides and is made of corrosion-resistant material, in which the thickness of the gas-tight jacket only increases Corrosion resistance is designed, is easy to manufacture and test.
  • the anchors are screwed into the base body on the one hand and welded to the jacket on the other hand. It is convenient if anchor and jacket are made of the same material.
  • the innovation is described in more detail by way of example with the aid of schematic illustrations I to IV.
  • a shielding container (6) contains a transport and / or storage container, consisting of a base body (1) with a base (2) and cover (3) made of an inexpensive metallic material.
  • the storage container contains radioactive material (7), for example irradiated fuel elements from nuclear reactors or radioactive waste from reprocessing plants.
  • Base body (1), bottom (2) and cover (3) are surrounded by a gas-tight jacket (4) made of corrosion-resistant metallic material.
  • the jacket (4) lies relatively tight on the storage container. Therefore, the gap (8) located between the jacket (4) and the base body (1) or base (2) and cover (3) is very small. It can be filled with helium or another gas to test the tightness of weld seams in the jacket (4) and in the lid or bottom area.
  • the jacket (4) is connected to the base body (1) including the cover and base area via anchors (5).
  • the number and distribution of the anchors (5) is adapted to the respective design needs.
  • the anchors (5) are advantageously made of the same material as the jacket (4) and fix the jacket (4), the thickness of which is dimensioned in a material-saving manner only with regard to the possibly expected maximum corrosion attack, against bulging when the internal pressure increases due to the heat producing radioactive inventory arises.
  • conical anchors (9) - Fig. II - can be used or bolt-shaped anchors (10) - Fig. III - which ver with one or more shoulders are seen.
  • such anchors (9, 10) penetrate the base body (1).
  • the anchors are screwed into the base body (1) as screw anchors (11) - FIG. IV - since in this way the base body (1) does not have to be drilled through.
  • the same is the case if the anchors (5) are inserted into the base body from the outside in the manner of an expansion dowel or a bayonet holder.
  • the corrosion-resistant jacket (4) is fastened to the anchors (5) embedded in the base body (1), for example by soldering or riveting. It has been found that welding the armature (5) to the jacket (4) is particularly favorable.
  • the outside of the anchor can either be flush with the outer surface of the jacket or set back. If necessary, it is also possible to screw the anchor (5) and the jacket (4) together.
  • the anchor (5) can also be composed of several materials if this results in fastening advantages in the base body.
