Definitions

  • the invention relates to a transport and storage container for heat-generating radioactive substances, in particular spent nuclear reactor fuel elements or HAW (high active waste) -Gaskaskillen
  • Transport and storage containers for radioactive materials or substances are well known in practice.
  • DE 197 34 166 A relates to a transport container with compartments for spent nuclear reactor fuel elements, which have already been enclosed gas-tight in capsules in the nuclear reactor.
  • Plate-shaped components made of absorber materials and moderator materials are attached to the inside of the radiation protection envelope of the transport container and shield fast neutrons.
  • Out EP 0 036 982 a basket for transport and / or storage containers for radioactive materials is known, which consists of graphite. Shafts for receiving the radioactive material are arranged in the graphitic insert basket.
  • EP 0 036 954 discloses a container for transporting and / or storing radioactive material, the neutron shield is disposed between the outer body of the container and the inner lining of the body.
  • the empty shafts remain regularly unused because they are too small.
  • For the shielding of the neutron radiation is a thermalization of the fast neutrons by hydrogen-containing materials in the container body or by external neutron moderators or - as a second possibility - by hydrogenated, borated materials, eg. As in the form of plastics, with additional Sekundärgammaabstrahlung, which are arranged on the outside of the container wall, accomplished.
  • the secondary gamma radiation leads to an increase in the total gamma dose rate at the outside of the container, in particular at weak points. Weaknesses of the neutron shield are regularly by means of additional shielding outside the container, eg. B. on his caddy, collected. Everything is very complicated and needs improvement.
  • the invention has the object of providing a transport and storage container of the type mentioned in such a way that the required reduction in the total level of neutron dose rate is achieved in a simpler manner than before.
  • the invention teaches a transport and storage container for heat-generating radioactive materials, in particular spent nuclear reactor fuel elements or HAW (high active waste) glass kokillen, consisting of a Neutronenmoderatormaterial having metallic container body with associated closure elements and arranged in the container body basket, which receiving shafts has empty wells for the radioactive substances and between the receiving wells, wherein at least the peripheral empty shafts are filled with graphite-containing neutron moderator material and wherein the neutron moderator material located in the empty shafts is at least partially provided with metal sheaths and wherein the metal sheaths are bolted to the container or are braced over the screwed to the container wall guide rails with the container body.
  • HAW high active waste glass kokillen
  • the invention is based on the recognition that graphite is not only an excellent neutron moderator material, but the high thermal conductivity and the radiation coefficient of the graphite also have extremely favorable effects on the heat dissipation. Consequently, the measures described also significantly reduce the temperature of the radioactive substances.
  • the peripheral empty shafts are designed like a whip.
  • the Neutronenmoderatormaterial exists preferably made of pressed graphite. It is advantageously formed columnar.
  • the neutron moderator material located in the voids is at least partially provided with metal sheaths according to the invention. These are inventively bolted to improve the heat conduction with the container body or clamped on screwed to the container body wall guide rails with the container body. For the same reason, it is also advisable to manufacture the metal shells made of copper or steel. Incidentally, it is also advisable to occupy head and / or foot-side container cavities with graphite.
  • the transport and storage container shown in the figure is intended for heat-generating radioactive substances, in particular spent nuclear reactor fuel elements or HAW (high active waste) glass molds and consists in its basic structure of a Neutronenmoderatormaterial 1 having metallic container body 2 with associated closure elements, not in detail are shown.
  • a support basket 3 is arranged, the receiving shafts 4 for the radioactive substances and between the receiving shafts empty shafts 5 has.
  • the peripheral empty shafts 5 are filled with graphite-containing neutron moderator material 1.
  • the peripheral empty wells 5 and, correspondingly, the neutron moderator material 1 located therein are designed like a whip.
  • this neutron moderator material 1 consists of pressed graphite columns. These graphite columns are provided over part of their circumference with metal sheaths 6 made of copper or steel, which are bolted to the container body 1. But you could also be clamped on bolted to the container body wall guide rails with the container head.
  • head and / or foot-side container cavities are also covered with graphite.
