Separative Cascade Shape Effect on the Isotopic Mixture Concentration in Cascade Holdup

  • Published:
Atomic Energy Aims and scope

Numerical studies are performed of the separation of a model multi-component isotopic mixture in a three-stream cascade. The particulars of isotope accumulation as a function of cascade shape (length, stage distribution of interstage flow) are examined. The regularities of the effect of the cascade shape on the component concentration in the cascade holdup are determined. An enriched isotopic mixture can be obtained by accumulation and partial removal of the process gas from the stages where the target component concentration is highest.
