Calculation of a squared-off cascade for simultaneous concentration of intermediate components

Background

Stable isotopes are widely applied in various fields. Unfortunately, their concentration in gas centrifuge cascades raises a number of problems. One of them is the enrichment of isotopes with intermediate masses, associated with their concentration in additional products of a multi-stream cascade.

Aim

To develop a calculation method for a multi-stream squared-off cascade with several additional products.

Materials and methods

Isotopes of ^92–100Mo contained in a seven-component mixture of molybdenum hexafluoride were studied. A computational experiment included the simultaneous concentration of ⁹⁵Mo and ⁹⁶Mo in two additional products of a three-section cascade.

Results

The results of the study have demonstrated the concentration of ⁹⁵Mo and ⁹⁶Mo above 59.5% achieved in additional products of the considered 60-stage cascade. Concentration can be carried out effectively without stream swirling at the section boundaries.

Conclusion

The proposed method can solve the problem of simultaneous concentration for intermediate components in several additional products of a single squared-off cascade. The developed method needs verification.
