Definitions

  • the invention relates to a shielding transport container for nuclear reactor fuel assemblies with a spherical cast iron container body which has a cover receptacle, and with a lid fitted into the cover receptacle, at least the cast body of the container body having a surface with open pores and an end layer made of a metal or from a metal alloy from the group "nickel, nickel-based alloy, austenitic chromium / nickel alloy".
  • a shielding transport container also regularly serves as a shielding storage container.
  • the cover fitted into the cover receptacle can also have an end layer made of a metal or a metal alloy from the group "nickel, nickel-based alloy, austenitic chromium / nickel alloy".
  • the invention further relates to a method for producing such a shielding transport container.
  • the invention also relates to a special use of a layer produced from a particle melt.
  • Shielding transport containers of the structure described and the intended purpose are regularly introduced into a corresponding fuel element pool of the nuclear power plant, in which water is located, and are filled with the fuel elements under water, as it were, for loading with the irradiated fuel elements.
  • the pool is regularly lined with stainless steel, for example 18/8 chrome nickel steel.
  • stainless steel for example 18/8 chrome nickel steel.
  • the container body made of cast iron is introduced, a galvanic element is formed, and in particular ferritic iron from the cast matrix is dissolved. This corrodes the stainless steel lining of the fuel element pool.
  • the surface of the container body is also adversely affected. To avoid all of this, the finishing layer is provided. This prevents the formation of elements and thus prevents ferritic iron from going into solution and the described corrosion phenomena occurring. This is especially true when working with nickel or a nickel-based alloy.
  • the final layer is applied with the aid of electroplating technology.
  • Appropriate galvanotechnical systems are required for this, which are very large because of the size of the shielding transport container are expensive.
  • Practice shows that the electroplated finishing layers in thin layers of up to 200 ⁇ m thick or even more are not up to the requirements of practice.
  • more or less punctiform open spots appear in the end layers. Studies which do not belong to the prior art have shown that these open areas are located above open pores which the cast body shows on its surface.
  • the end layers have been made to be extremely thick, for example with layer thicknesses of 1.5 mm, 2.00 mm and more, as part of the electroplating application of the end layers. This is also complex and nonetheless not sufficiently secure.
  • the invention has for its object to provide a shielding transport container of the structure described above and the intended purpose described above, which can be filled in a water basin with irradiated fuel elements, which has an all-round end layer made of a metal or a metal alloy of the group " Nickel, nickel-based alloy, austenitic chromium / nickel alloy ".
  • the invention is also based on the object of specifying a method which is particularly suitable for applying such an end layer.
  • the invention first teaches that the closing layer has the texture of a layer solidified from a particle melt, the particles of which have a diameter which is smaller than that of the open pores, and that the closing layer also fills the open pores.
  • the texture can correspond to the solidified layer of a powder melt. This means that the layer was built up from powder.
  • the texture can also correspond to that of a drop melt. This means that the layer was made up of fine drops.
  • the melting of the particles to form the layer, which has the described texture can be done in any way and make use of the tools of modern metal coating technology.
  • the invention is based on the knowledge that a final layer, which has the texture of a layer solidified from a particle melt, surprisingly also fills the open pores of the cast body if the particles have a diameter which is smaller than that of the open pores. It goes without saying that the diameter of the particles must be sufficiently small. Particularly suitable diameters can easily be determined by experiment taking into account the pore size. Since the problems described at the beginning no longer occur in the shielding transport container according to the invention, because there are no longer open pores of the cast body under the closing layer, very thin layer thicknesses of the closing layer can be used according to the invention. In this context, the invention teaches that the final layer has a thickness of up to 200 microns. The final layer preferably has a thickness of approximately 100 ⁇ m.
  • the surface of the cast body of the container body can be machined and the final layer can be applied to the mechanically machined surface.
  • a mechanically processed surface of the cast body has the pores described at the outset, because during the mechanical processing in particular the spherical graphite components in the cast matrix are torn out of the latter.
  • the final layer to the merely cleaned surface of the cast skin of the cast body. This also owns regularly fine pores which are closed according to the invention.
  • a laser coating method is preferably used according to the invention.
  • the subject of the invention is a method for applying the final layer to the cast body of a shielding transport container, this method being characterized in that the particles are combined by at least one laser beam of sufficient energy to melt the particles.
  • the laser beam forming an interaction zone with the surface, is directed onto the surface to be coated and is moved in paths along the surface to be coated, the particles being introduced into the interaction zone.
  • the particles can be applied or introduced as powder using a spray nozzle. However, the particles can also be applied or introduced using the plasma spraying method.
  • a cast body made of spherulitic cast iron which belongs to the container body of a shielding transport container for irradiated nuclear reactor fuel elements. It can be seen that the cast body 1 has a surface 2 with open pores 3.
