摘要
FIELD: treatment plants.
SUBSTANCE: invention relates to methods of purifying raw material contaminated with harmful isotopes for further usage in production of reduced uranium for nuclear fuel. Method of purifying contaminated raw material for separating production from harmful isotopes consists in reducing concentration of isotopes 232U, 234U, 236U by processing uranium hexafluoride of contaminated raw materialin double cascade of gas centrifuges. Uranium hexafluoride of contaminated raw materialis processed in double cascade of gas centrifuges intended for producing low-enriched hexafluoride 235U from pure uranium hexafluoride supplied for the main feed of the first cascade, contaminated raw materialis supplied for additional feed of the first cascade.Purified raw material is taken from the first or second cascade.
EFFECT: invention enables to obtain high-quality raw material with allowable content of limiting harmful isotopes.
