Abstract

A method is developed for determining the optimal parameters of a cascade for separating multicomponent isotopic mixtures with a prescribed output concentration for the target isotope. The method is flexible with respect to cascade efficiency criteria. It is based on a systematic calculation of the parameters of a counterflow symmetric cascade with prescribed structural parameters and waste concentration of steps with respect to the valuable (as a rule, the light) isotope. The computational procedure developed includes iterative refinement of the initial approximations of the concentration of nontarget isotopes in the steps. The waste concentration of the steps with respect to the target isotope is varied in order to find the best cascade variant in accordance with the optimization criterion chosen. The properties of cascades optimized with respect to the criterion of minimum total flux are investigated. It is shown that they differ from the nonmixing criteria with respect to the separated isotopes that are conventionally used in the theory of multicomponent separation.
