Investigation of centrifugal enrichment of stable nickel isotopes

Separation of Multicomponent Isotope Mixtures by Gas Centrifuge

“…As seen from Eqs. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19), all parameters of the multicomponent mixture flow are complexly interconnected with each other and depend on the space distribution of component concentrations. The definition of flow parameters and distribution of concentrations is a sophisticated problem even with the use of modern numerical methods.…”

“…First investigations on separation of multicomponent mixtures of stable isotopes by gas centrifuge a patient. For production of final targets containing radioisotope Ni-63, an efficient separation technique based on gas centrifuge technology has been developed (8). Radioisotope I-123, widely used in medicine, was offered to be produced from highly enriched by gas centrifuges Te-123 (up to 96.5%) after irradiation with protons in a cyclotron (9).…”

Highly Enriched Nickel‐63 Radionuclide for β‐Voltaic Nuclear Batteries

“…The development of centrifugal technology for nickel isotope production allows obtaining nickel isotopes in sufficient amounts. [16] This process (first enrichment cascade in Figure 6) describes the formation of enriched Ni-62 (62-79.4 %) from natural nickel (3.63 % of Ni-62). This Ni-62 is used as the target for irradiation in the nuclear reactor.…”
