Cascades with Flow Expansion for Simultaneous Concentration of Intermediate Components
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 183W and 184W 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.
