“…The negative impact of 236 U implies parasitic capture of neutrons, which results in the necessity to increase 235 U concentration in the nuclear fuel as a compensating measure. Different cascade methods and dilution procedures [2][3][4][5][6][7][8][9] are offered in order to reduce the contents of 232,234,236 U. These methods allow to partially solve the problem of reducing the concentrations of 232,234,236 U but they still have certain drawbacks.…”

Reprocessed uranium gained from the spent nuclear fuel contains 232, 234, 236U isotopes within, which considerably hamper its reuse. It is proposed to use an ordinary cascade to reduce the concentration of 232, 234U. The output purified from 232, 234U is obtained in the cascade waste. The authors analysed the peculiarities of reducing concentration of 236U after the enrichment of reprocessed uranium hexafluoride in terms of 235U in the ordinary cascade and its subsequent dilution. A computational experiment was performed. Parameters of cascade stages were predetermined, which allow to reduce the content of 232, 234, 236U to an acceptable level.
