摘要 |
FIELD: recovery of spent nuclear fuel. ^ SUBSTANCE: proposed method involves enhancement of uranium-235 isotope content in recovered uranium to 2.0-5.0 mass percent while reducing absolute and/or relative concentration of uranium even isotopes. Method includes division of isotope mixture of raw uranium reagent in gas-centrifuge isotope-division cascade and mixing of separated commercial isotope mixture with uranium thinner. Isotope mixture division is effected in two-cascade arrangement. Raw uranium reagent is enriched with uranium-235 fissionable isotope in first single cascade up to content over 90 mass percent. Second single cascade is used for cleaning isotope mixture from uranium-232 and uranium-234 isotopes. Select flow of second cascade enriched with uranium-235 isotope is conveyed as commercial isotope mixture for mixing up with uranium-thinner. ^ EFFECT: enhanced quality of reducing recovered uranium and minimized uranium-thinner requirement. ^ 12 cl, 1 dwg, 6 tbl |
