[en] As it is know the problem of non-uranium isotope separation by a gas centrifuge (GC) has some specific features differing it from the case of the binary isotope mixture of U F₆. among these features is the multicomponent composition of most non-uranium isotope mixtures and the associated difficulty to separate the desired isotope intermediate with respect of the molecular mass. Besides a noticeable difference in the properties of the working (process) gases used in the separation of non-uranium isotopes from the well-known properties of uranium hexafluoride, an additional optimization of the circulation flow in the GC is necessary to enable the increase the axial separation effect. For the GC production of the isotopes of various chemical elements their different gaseous chemical compounds, such as fluorides, oxyfluorides, metal-organic compounds, etc. area currently used. In the present report the separation of isotope mixtures is considered regarding only two sorts of chemical compounds: fluorides compounds and noble gases with the molecular masses from 40 to 240. The molecular-kinetic parameters of the studied working mixtures, required for calculation but very often unavailable in the handbooks were calculated and some of them were measured in experiments.

[en] The procedure of the numerical technique adjustment on the selected type of the gas centrifuge is considered. A satisfactory agreement is shown between theoretical and experimental results for enrichment of sulfur or tellurium isotopes in a single gas centrifuge. (orig.)

[en] The feasibility of enriched chromium-50 production by different methods of isotope separation are estimated. It is stated that about 800 g of highly-enriched (above 90%) ⁵⁰Cr and 40 kg of ⁵⁰Cr enriched to about 40% were produced using Russian centrifuge cascades for experiments on detecting solar neutrinos.
