“…The idea of using such a cascade is based on the fact that the concentration distributions of components with intermediate masses can reach maximum values at the inner stages of the cascade. Therefore, it is possible to obtain the concentration of the intermediate isotope significantly higher than limiting value, if to turn on an additional withdrawal (the flow E in figure 3 with concentrations C i E ) near the stage, where the maximum is reached [16]. In addition, one can get relatively high concentrations of the lightest and heaviest isotope in the flows P and W.…”

“…Therefore, the additional withdrawal from the stage near such a maximum, provides isotopic composition with the concentration of the intermediate component, which is greater than the theoretical limit for three-flow cascade. In some cases, it is possible to obtain relatively high concentrations of two intermediate components simultaneously in a cascade with two additional product flows [15][16][17].…”

Original techniques were proposed for calculating and optimizing double cascades (DC) built of square cascades and a square cascade with an additional product flow (SCAP). Both cascade schemes (DC and SCAP) were tested in solving a task of simultaneous enrichment of three components of a model mixture to a pre-defined level. A comparison of the DC and SCAP efficiency was made according to the minimum of total cascade flow. The results have shown that the double cascade is more efficient in terms of the chosen criterion.

One of the important stages in the campaign for separation of multicomponent isotopic mixtures is bringing the separation cascade to a stationary mode of operation. This process, depending on the applied separation method, can be characterized by a relatively long time with associated consumption of the working substance and operating costs. Therefore, the search for the values of the control parameters of the cascade at which it is possible to reduce the transient process time is practically a significant problem in the theory of isotope separation in cascades. One of the current trends in the modern theory of cascades is the study of physical laws of stationary mass transfer in cascades with additional outgoing flows. Such cascades can find application for solving a number of urgent problems, in particular, obtaining relatively high concentrations of isotopes with intermediate masses. At the same time, the laws of unsteady mass transfer in such cascades remain poorly understood. The paper analyses the key patterns of transient processes in a square cascade with an additional product flow. The interconnections between the time of bringing such a cascade to the stationary mode and the external conditions under which the process of separation of the mixture occurs are revealed.
