Abstract (en)
[origin: EP3671762A1] The invention relates to the field of production of radioactive isotopes and more specifically to the technology of production of the radioactive isotope Nickel-63 that is used to manufacture beta-voltaic current sources.The method for producing Nickel-63 radionuclide involves obtaining an initial nickel target enriched in Nickel-62 to get the content as high as 98% or more, the bombardment of the target in the reactor and the enrichment of the exposed product into a light fraction. The initial nickel enriched in Nickel-62 is added to the light fraction until it reaches a content of 98% or more, and is used to make a secondary nickel target. The remaining heavy fraction is converted into a metal form and used for the manufacture of beta-radiation sources that are applied in beta-voltaic current sources.After the bombardment, the solution of the nickel target is subjected to radiochemical cleaning to remove Cu-65 and gamma-active isotopes, in particular Fe-59 and Co-60.The technical result consists in the most complete loading of the reactor cell with Nickel-62 isotope and an increase in the amount of Nickel-63 radionuclide produced.
