Definitions

  • the invention relates to a multi-layer storage container for storing radioactive material, in particular for long-term storage of irradiated fuel elements, in suitable geological formations, consisting of a container body and a lid, each made of at least two layers of material.
  • Irradiated fuel assemblies are either processed immediately after temporary storage in water basins or after a further limited storage period.
  • the nuclear fuel and nuclear fuel are separated from the fission products and again uel cycle supplied to the B.
  • the fission products are conditioned by known methods, usually using large quantities of valuable substances, such as lead and copper, and are virtually no longer removable in geological formations.
  • Containers made of alloyed and unalloyed steel, copper and corundum are proposed as packaging for radioactive materials and irradiated fuel elements.
  • the steel containers are either not corrosion-resistant or, like copper, are very expensive.
  • Container made of corundum are basically g e is, however, the need for making experiences are missing.
  • the fuel elements for packaging would have to be disassembled into small corundum containers for manufacturing reasons, which is associated with considerable effort.
  • the E rfindüng is therefore based on the task of creating a multilayered container for the storage of radioactive material, in particular for the long-term storage of irradiated fuel elements, in suitable geological formations, consisting of a container body and a lid each made of at least two layers, which is not complex and has sufficient strength and barrier functions over a longer period of time.
  • the inner layer consists of a mechanically stable, inexpensive material and the outer layer consists of a material which is corrosion-resistant with respect to the storage medium.
  • metallic materials such as alloy steels, tantalum, lead, are suitable.
  • Ceramic materials such as the oxides of aluminum, silicon, magnesium, the carbides of silicon or boron, and spinels, silicates and graphite, are also suitable in some cases. Materials based on zirconium and titanium are preferably used.
  • the thickness of the outer layer is advantageously such that it corresponds to the removal during the time in which the barrier effect is to be retained even in the worst case, and reliably protects the inner layer against corrosion for the duration of the intended storage.
  • the required layer thickness is determined taking known corrosion data into account.
  • the outer layer is preferably applied to the inner layer by plating or by flame or plasma spraying. Since the closed containers can be sprayed in one operation, seamless coatings can be obtained.
  • the filled storage container is closed by a two-layer cover, which can also be designed as a double cover.
  • the inner cover, or the inner cover layer is made of the same material as the inner layer of the container body and can have a thread in the lower part for screwing the cover into the cylindrical part of the container.
  • a pin with an internal square for example, can be screwed into the cover. After screwing in the lid this inner cover is welded gas-tight by a fillet weld.
  • the pin is made of the same material as the outer corrosion protection layer of the container body and the outer cover, or the outer cover layer, which is to ensure the corrosion protection. As a result, the material of the base body is completely protected without the pin having to be plated, which would mean a considerable outlay.
  • other locking mechanisms known per se can also be used.
  • one or more cavities for holding helium can advantageously be introduced between the material layers of the cover.
  • Figures I and II schematically show two exemplary embodiments of the storage container according to the invention.
  • Figure I shows a storage container, the container body (1) and lid (2) each consisting of an inner layer (3) and an outer layer (4).
  • the inner layer (3) a fine grain steel WSTE 43 is chosen, a heat-resistant structural steel. Its corrosion resistance is poor, its strength is good, and the steel is also easy to weld. Its low price is a great advantage, especially compared to heat-resistant tempering steels, which are also suitable.
  • Zircaloy-2 is g ut weldable and inexpensive compared with the likewise g ut suitable materials based on titanium, such as titanium or Ticode 12th
  • a layer thickness> -4 mm is selected, for example.
  • the Zircaloy plating can be applied in two different ways. Either a cover made of Zirkaloy-2 is prefabricated, pulled over the inner container and shrunk on, or the prefabricated Zirkaloy sheets are applied to the base body by roll welding plating. Both versions are almost equivalent.
  • the container is then loaded and closed with the lid (2), which is designed as a "double lid with inner (5) and outer lid (6). Leak tests are carried out between the inner (5) and outer lid (6) or several cavities (7) filled with helium.
  • the container interior (8) can be poured out with a metal, for example lead, after loading with the spent fuel elements.
  • Figure II shows a container in which the outer layer (4) consists of two individual layers (°, 10), the material of the inner individual layer (10) compared to the outer individual layer (9) nobler in terms of its position in the electrochemical series is. In the event of corrosion breakthroughs (for example pitting) of the outer individual layer (9), this prevents the load-bearing inner layer (3) from being corroded. Furthermore, this storage container inside the container (8) additionally consists of an inner container (11) for receiving the radioactive material.
