Calculation of Multistage Schemes for Concentrating Isotopes in a Gas-Centrifuge Cascade with Variable Separation Factors

A method is proposed for calculating a gas-centrifuge cascade with variable separation factors depending on their feed flow and flow division factor. On its basis, a computational experiment was performed on the separation of germanium tetrafluoride, nickel trifluorophosphine, and tungsten hexafluoride in a cascade with a specified number of gas centrifuges in steps. The most efficient multistage separation schemes for the production of highly concentrated isotopes were determined.
