FIELD: power industry. ^ SUBSTANCE: separation of uranium isotopes in the form of hexafluoride of isotopic mixture of uranic regenerate on the installation consisting of two subsequent gas centrifugal stages; at that, hexafluoride of uranium recovered as per isotopic composition is obtained in flow of the second stage bleeding powered with heavy fraction of the first stage, which has been obtained during enrichment of light fraction of the first stage with 235U isotope to the concentration not exceeding 20 wt %. Isotopes are separated at the first stage so that there obtained is concentration of isotopes 232U and 234U in heavy fraction of the first stage, which provide required concentrations 232U and 234U at the second stage bleeding, and isotopes are separated at the second stage till the second stage bleeding flow is saturated with isotope 235U, which ensures the required concentration of isotope 236U in the second stage bleeding flow. ^ EFFECT: eliminating hazardous high concentrations of fissionable isotope 235U. |
