Definitions

  • the invention relates to a transport and / or storage container for radioactive substances, in particular for irradiated fuel elements from nuclear reactors, consisting of a container body with a shielding function for gamma radiation with cooling fins on the surface, a corrosion-resistant, adjacent to the container body, via a flange in the container body secured inner lining, a shielding lid fastened with screws in the container body and an outer lid, a neutron shielding, supply lines, test connections and webs between the cooling fins.
  • Containers that are used for the transport and / or storage of spent fuel elements must contain the radioactivity of the imported goods and must prove in strict tests that this is guaranteed even in extreme accident situations. At the same time, however, they must also shield the y and n radiation released in the radioactive decay reactions and safely dissipate the heat of decay to the outside.
  • Known containers such as described in DE-A-22 28 026, therefore consist of thick-walled, with cooling fins metallic container bodies that ensure the necessary strength and the gamma radiation shielding, a screw-attached shield and an outer cover, a neutron shield, and an inner lining , which ensures corrosion protection and decontamination.
  • the inner linings are preferably designed as removable inner containers.
  • the inner lining is either fixed to the container body by holding-down devices or fastened in the lid area by screws, both solutions that are complex.
  • the inner lining is broken through the threaded holes for the cover screws and the container body is thus exposed to the corrosion attack f.
  • the space requirement for this screw system is also disadvantageously large.
  • the object was achieved in that the inner lining with the external thread of threaded inserts is fastened via a seal in the container body and the threaded inserts have axial bores with an internal thread into which the screws for fastening the shielding cover are screwed.
  • Threaded inserts have long been known per se, but not for transport and storage containers that are many tons heavy and have to withstand all mechanical accident loads.
  • Figure 1 shows a section through a container according to the invention
  • Figure 2 shows the connection of the container body / inner lining / shielding cover.
  • the transport and storage container consists essentially of a container body (1) with cooling fins (5), a corrosion-resistant inner lining (4), a shielding cover (2) provided with sealing elements (15) and an outer cover (3) also equipped with seals (14) ), a neutron shield (8), supply lines (11) and trunnion (7).
  • the inner lining (4) lies against the container body (1), the inner lining flange (19) being provided with bores through which threaded inserts (21) with external threads (22) are screwed to the container body (1).
  • the shielding cover (2) is held with screws (20), which are seated in axial bores with an internal thread (23) inside the thread inserts (21).
  • the head (25) of the threaded insert (21) is designed accordingly for easy handling.
  • a seal (24) on the threaded insert (21) prevents the ingress of water during underwater loading.
  • the axial bores of the threaded inserts (21) can be closed or covered with the container open.
  • test connections (9) in the outer cover (3) which are protected by covers (28).
  • test connections (9) it is possible to monitor the intermediate space (16) between the two enclosures or barriers, which through the inner lining (4) and the shielding cover (2) on the one hand and the container body (1) and the outer cover ( 3) on the other hand.
  • a leak detector that is connected to a test connection (9) without being exposed to a radiation hazard.
  • measuring devices it is also possible to connect measuring devices to a test connection (9) for locating the activity which may have occurred in the intermediate space (16).
  • the equipped in this way storage container is, for. B. for long-term interim storage of radioactive material that is to be reprocessed later, ideally suited.
  • the container according to the invention has webs (6) on the surface which are attached transversely to the direction of extension of the kipper ribs (5) provided with notches (18).
  • the webs (6) run all around, but with axial cooling fins, they run axially.
  • the joint casting of the cooling fins (5) and webs (6) onto the container body (1) has proven to be particularly favorable.
  • the supply line (11) to the lowest point of the container body (1) is arranged in the interior of the container and is connected to an operating connection (10) in the shielding cover (2) via a connecting element (12), wherein it is pressed by a spring element (13).
  • the container according to the invention is preferably made of cast iron, spheroidal graphite cast iron has proven to be particularly favorable.
