Definitions

  • the invention relates to a container with a variable shield and necessary facilities for the transport and / or storage of radioactive materials, in particular irradiated fuel elements from nuclear tractors.
  • containers are required that safely retain the radioactivity of the goods.
  • the construction of these containers is therefore subject to strict regulations, especially as regards the indestructibility of the container in the event of an accident and the protection of the environment from radioactive rays.
  • the containers for the transport and storage of irradiated fuel assemblies must therefore be of a stable and robust construction and offer protection against radioactive rays.
  • the material for radioactive shielding should be chosen so that the weight of the shield, which accounts for the largest part of the weight of the transport container, is kept as small as possible for economic reasons. It is also important to ensure that the decay heat of the transported or stored fuel elements can be safely dissipated to the outside.
  • the shielding of the containers must retain all of the biologically active radiation, which is preferably done by means of a coating made of uranium, lead or steel, which primarily absorbs the gamma radiation. Added to this is the neutron shielding, which is usually installed between the cooling fins, occasionally also in channels in the main body of the container.
  • a disadvantage of known shielding containers is that the thickness of the shield against the radioactive gamma radiation corresponds to the maximum design case provided for transport or storage.
  • the transports and when used as storage containers, e.g. B. contain spent fuel that has decayed so far in the fuel pool of the nuclear power plant that in these cases the shield is oversized.
  • the shield is oversized.
  • the disadvantage is that although a variance in heat dissipation and possibly neutron shielding is achieved, it is practically not in shielding against gamma radiation.
  • two-part shielding containers consist of a relatively simply designed thin-walled inner container with a barrier function, which is interchangeably located in an outer container with a shielding function and with cooling fins, another outer container designed for this purpose being used in accordance with the radioactive inventory of the inner container.
  • a barrier function which is interchangeably located in an outer container with a shielding function and with cooling fins
  • another outer container designed for this purpose being used in accordance with the radioactive inventory of the inner container.
  • the object was achieved in that the shield is applied in whole or in part as a metal winding on the container.
  • the container according to the invention is shown schematically in exemplary embodiments in Figures I to IV.
  • the container jacket is wrapped with a metal winding 2, which has a gamma shielding function.
  • the metal winding 2 is applied in several layers in some cases.
  • the winding 2 is relatively easy to apply or remove by rotating the container 1.
  • Suitable as winding 2 are metal tapes made of good gamma-absorbing material, in particular steel. It is particularly favorable to use 2 wires or cables for the metal winding.
  • the metal winding 2 can be laid between the cooling fins 9, which may be located on the container 1.
  • the cavities 6 present in the metal winding 2 are advantageously filled with neutron shielding material. Pourable hardening plastics with neutron shielding properties are particularly suitable for this.
  • the container according to the invention enables the gamma radiation shield to be adapted in a surprisingly simple and effective manner to the radiation inventory located therein.
