An analytical determination of the concentration of admixed component in the product and waste streams of a multistream cascade separating a multicomponent isotopic mixture is examined. It is proposed that the solution of the systems of differential equations describing the variation in the concentration of the components of a mixture over the steps assuming the enrichment effects to be small be used. The general approach to obtaining analytical relations for the evaluations is shown for the example of cascades with several feed and product streams. Calculations of uranium cascades are performed, showing good agreement between the analytical determinations and the numerical calculations for the separation of natural and waste depleted uranium hexafluoride obtained from regenerated uranium.
