Definitions

  • the invention relates to a container for the transport and / or storage of radioactive substances which emit ⁇ - and n-radiation and generate appreciable residual heat, consisting of a container body with a shielding function for and n-radiation and an inner lining.
  • Containers that are used for the transport and / or storage of spent fuel elements must safely contain the radioactivity of the goods brought in and demonstrate in rigorous tests that this is guaranteed even in extreme accident situations. At the same time, however, they must also shield the gamma and neutron beams released during the radioactive decay reactions and dissipate the heat of decay to the outside. The shielding function must be largely retained even after an accident.
  • Known shielding containers mostly consist of a metallic basic container with the required mechanical strength and the wall thickness required to shield the gamma rays, usually made of steel or a combination of lead and steel, and an outer shell made of neutron shielding material, mostly organic substances with a high hydrogen content or in the form of a Water jacket.
  • a disadvantage of these constructions is that even slight collisions of the container, as can also occur during routine operation, can damage the neutron shielding and then a costly one Require repair of the entire container. In the event of a serious accident, characterized by high impact forces and exposure to fire, this neutron shielding can fail completely and the dose rate in the vicinity of the container can increase.
  • a container for the transport and / or storage of radioactive substances, in particular for irradiated nuclear fuel elements and highly active waste consisting of a base body with a shielding function for ⁇ -and n-radiation and an inner lining made of corrosion-resistant material has a further n-shield which is resistant to the effects of external accidents, in order to maintain sufficient shielding action if the outer n-shield is lost.
  • this additional shielding should not hinder the dissipation of the decay heat from the interior of the container.
  • n-shield in the form of a graphite-based material is additionally arranged between the inner lining and the base body.
  • the position according to the invention of the additional n-shielding within the solid base body ensures the best possible protection against mechanical and thermal damage.
  • the use according to the invention With its moderating properties, graphite provides additional n-shielding and at the same time fulfills the requirement of good thermal conductivity. Furthermore, there is excellent resistance to elevated temperatures, such as those which occur during normal operation of the container and in particular when exposed to an accident fire.
  • the n-shielding layers on the outside of the base body and the inner n-shielding according to the invention can be dimensioned such that, depending on the requirements, the inner or outer shielding layer makes the predominant contribution to shielding against neutron beams under normal operating conditions.
  • I, II and III illustrate the invention schematically and in more detail by way of example.
  • the transport and / or storage container consists of a base body (1), for example made of steel, on which cooling fins (2) and an outer n-shield (3) are arranged in a manner known per se.
  • the interior (4) of the container for receiving the radioactive material is formed by the inner lining (5) made of corrosion-resistant material, for example stainless steel, and a shielding cover (6), which also carries n-shielding material (3) on its outside.
  • the cover zone is protected against mechanical and thermal influences by a protective hood (7).
  • An n-shielding layer (8) made of a graphite-based material is additionally arranged in the annular gap between the lining (5) and the base body (1) as a further neutron shielding.
  • This graphite-based shielding layer (8) preferably consists of a mixture of graphite powder and a hardening binder, such as water glass or, above all, a cast resin.
  • This mixture can either be introduced as such into the annular gap between the base body (1) and the inner lining (5) and hardened, or it can advantageously be prefabricated graphite moldings (9), z. B. in the manner of composite plasters that are adapted to the gap dimensions can be used. These fittings can also be covered with a metallic jacket (10), preferably made of neutron-absorbing material. It is also possible to press a stampable graphite mass into the annular gap.
  • the function of the inner lining (5) can be carried out particularly advantageously by the metallic shells (10) which surround the graphite moldings (9).
  • the separate inner lining (5) can then be omitted partially or completely.
  • the graphite shaped pieces (9) are then attached particularly inexpensively to the inside of the base body (1), for example by guide rails (12).
  • guide rails (12) for example by guide rails (12).
  • other types of attachment such.
  • the shielding layer (8) can be easily adapted to the respective requirements by changing graphite moldings (9) of different thicknesses.
