Definitions

  • the invention relates to a transport and / or storage container for receiving at least one radioactive element, with container casing and container bottom and with at least one container lid.
  • Radioactive elements means above all spent or fresh fuel.
  • an axial free space is generally also present within such a fuel element between the fuel rods and the head of the fuel assembly.
  • the US 2003/015541 describes a transport and / or storage container for radioactive elements of sheath, bottom and lid. Between the radioactive element and cover is an axial clearance and between the radioactive element and cover a plastically deformable shock absorber made of balsa wood is arranged.
  • the US-B-6,280,127 describes a transport and / or storage container for radioactive elements of sheath, bottom and lid. Between the radioactive element and the lid is an axial clearance and between the radioactive element and cover a plastically deformable shock absorber is arranged.
  • the US-A-5 337 917 describes a transport and / or storage container for radioactive elements of sheath, bottom and lid. Between the radioactive element and cover is an axial clearance and between the radioactive element and cover a plastically deformable shock absorber made of aluminum-metal mesh material is arranged.
  • the DE 22 56 879 A describes a transport and / or storage container for radioactive elements of sheath, bottom and lid. Between radioactive element and lid is an axial clearance and between the radioactive element and cover is a plastically deformable shock absorber (wooden parts which act plastically deformable shock absorbing arranged.
  • the invention is therefore the technical problem of specifying a transport and / or storage container of the type mentioned, in which the disadvantages described above are avoided and is characterized in free fall with cover-side impact by strength or stability and thus safety.
  • the invention teaches a transport and / or storage container according to claim 1.
  • the radioactive elements are preferably spent or fresh fuel elements or HAW glass kokillen. It is also within the scope of the invention that in a conventional manner a basket for receiving the radioactive elements in the receiving space is available.
  • the transport and / or storage container comprises a lid system with several lids, for example a primary lid and a secondary lid
  • container lid means the inner lid immediately adjacent to the receiving space for the radioactive elements, for example the primary lid.
  • - Vertical installation state of the container means, in particular, that the container with its bottom or with the container bottom rests on a substrate and the container lid is oriented on the top side of the container.
  • the shock absorber is plastically deformed in a free fall of the container with impact of the container top or the container lid.
  • this plastic deformation can result from the fact that the entire radioactive element or the entire fuel element with its head piece impacts the shock absorber.
  • the plastic deformation can also result from the fact that the fuel rods of a fuel assembly are delayed impact on the head of the fuel assembly and that resting on the shock absorber or bouncing on the shock absorber head then causes the plastic deformation of the shock absorber.
  • the shock or momentum emanating from the fuel rods is transmitted from the header to the shock absorber.
  • That the shock absorber is plastically deformable means in the invention that the shock absorber is permanently deformed.
  • plastic deformability differs from elastic deformability, which is transient and transforms kinetic energy into potential energy, which then at least partially reverts to kinetic energy.
  • the plastically deformable shock absorber is therefore not an elastically deformable spring element, such as a helical spring or the like. Such spring elements have not been proven for the purpose of the invention.
  • the shock absorber according to the invention is primarily plastically deformable and at most slightly elastically deformable.
  • the radioactive element is a fuel assembly with a head piece and arranged below the head piece fuel rods and that a first axial clearance in the vertical installation state of the container between the head piece and the container lid is present.
  • the axial clearance in the vertical installation state is assigned to a corresponding axial distance f between the head and the container lid.
  • a second axial clearance in the vertical installation state of the container between the fuel rods and the head piece is present.
  • This axial clearance is to be assigned a corresponding axial distance a between the top of the fuel rod and the head piece.
  • the fuel rods form part of the radioactive element (fuel element).
  • the second axial clearance which is of course also arranged between the parts of the radioactive element (fuel rods) and the container lid, is thus located between the fuel rods and the head of the fuel assembly.
  • the claimed in claim 1 first axial clearance and second axial clearance so add up to the entire axial free space that extends between the fuel rods (parts of the radioactive element) and the container lid.
  • the second axial clearance is the most important with regard to the solution of the problem according to the invention.
  • the mass of all fuel rods accounts for about 90% of the mass of a fuel assembly.
  • the fuel rods bounced delayed on the head and this results in a very significant burden on the lid system. Due to the plastic deformation of the shock absorber according to the invention in particular this impact of the fuel rods can be effectively compensated or intercepted, so that the load on the container lid or the lid system is no longer critical.
  • the shock absorber is arranged between the head piece of a fuel assembly and the container lid.
  • a plurality of fuel elements are usually added.
  • a shock absorber is then arranged between each head piece of a fuel assembly and the container lid.

  • the hollow cylinder has a length of 230 mm, an outer diameter of 75 mm, an inner diameter of 55 mm and a wall thickness (of the hollow cylinder jacket) of 10 mm.
  • the shock absorber consists of a metal, preferably of a light metal or a light metal alloy and very preferably of aluminum or an aluminum alloy.
  • the material chosen for the shock absorber is a corrosion and water resistant material.
  • a shock absorber in the form of a hollow cylinder made of a metal, preferably made of a light metal or a light metal alloy and very preferably made of aluminum or an aluminum alloy is used.
  • the inner shock absorber is designed with the proviso that upon impact of the container on the container lid (or on the top of the container), the plastic deformation of the inner shock absorber over the elastic deformation of the inner shock prevails. It is within the scope of the invention that the elastic deformation of the inner shock absorber is negligible.
  • the fact that the inner shock absorber is designed with the proviso that the plastic deformation is achieved, means in the invention in particular that the material, the dimensions and the wall thicknesses of the shock absorber are set up accordingly.

  • the majority of this kinetic energy is converted into deformation energy of the plastic deformation.
