Definitions

  • the invention relates to a container for long-term storage of radioactive substances, in particular irradiated fuel elements, in suitable geological formations with cathodic protection by means of a direct current source connected to an anode.
  • Irradiated fuel assemblies are either processed immediately after temporary storage in water basins or after further interim storage.
  • the nuclear fuels and broods are separated from the fission products and returned to the fuel cycle.
  • the cleavage products are made by known methods, usually using large amounts of valuable materials, e.g. Lead and copper, conditioned and in geological formations such as salt domes practically no longer removable.
  • metal containers e.g. B. from steel, cast iron, especially spheroidal graphite cast iron, lead, copper or other materials have disadvantages. These are u. a. partly in the production costs, but especially in the corrosion area, because u. a. Water ingress, even if it is unlikely to occur, must be included in safety considerations.
  • This object was achieved in that one or more isotope batteries are used as a direct current source.
  • the container is protected cathodically against corrosion by forming an electrochemical macro-element from the container and a foreign electrode in a manner known per se, in which the container represents the cathode.
  • a direct current source is used which keeps the superimposed protective current in such a way that it always has a higher voltage than the micro or macro elements which are produced. Characterized an S carried p annungskompensation the forming upon contact of the metallic container material with the moist environment of local elements.
  • thermocouple Wires made of iron / constantan, copper / constantan, nickel / chrome-nickel, platinum / platinum rhodium, gold / silver, gold cobalt / silver gold, lead / tellurium etc. can be used for the thermocouple. The selection depends on the required thermal voltage and the necessary corrosion resistance.
  • the area in which the hot soldering point is arranged can also be insulated in order to have particularly high temperatures at this point so that correspondingly high thermal currents flow.
  • several thermocouples can also be connected in series. In indirect conversion, so-called " ⁇ phosphor, usually zinc sulfide activated with silver, is applied to photo elements.
  • the arrangement according to the invention also protects containers which are provided with electrically non-conductive coatings to a particular extent, since then only the points at which there are pores through which the corrosive medium reaches the metal have to be protected.
