CASCADES WITH FLOW EXPANSION FOR SIMULTANEOUS CONCENTRATION OF INTERMEDIATE COMPONENTS

摘要

A cascade scheme allowing two intermediate-mass isotopes to be concentrated in a single cascade above the maximum admissible concentrations at the outputs of ordinary cascades is proposed. A cascade with two flow expansions and two additional product flows is used for this. For the example of a mixture of tungsten isotopes, it is shown that the concentrations of W-183 and W-184 can be increased simultaneously up to 70 and 80%, respectively. In addition, additional product flows can be equal to 50-70% of the primary (end) product flow of the cascade.
