Separating Stable Boron Isotopes in Uniflow Gas Centrifuges

Resumo

A variant of a model of a uniflow gas centrifuge for separating a binary mixture of boron isotopes in the trifluoride form, taking account of the interaction of the rotating gas with a stationary cylindrical central body, is proposed. Expressions are obtained for the maximum admissible enrichment and separation factors and the optimal separative power as functions of the radius of the central body. It is shown that a cascade of uniflow gas centrifuges with more than 95% enrichment of boron trifluoride in terms of the ¹⁰B isotope in the requisite quantities for industry can be built in practice.
