Aerodynamic isotope separation

Mailing, G. F., and E. Von Halle Aerodynamic Isotope Separation Processes for Uranium Enrichment, U.S. ERDA Report K/OA-2872, Oct. 7, 1976. 

The basic idea of aerodynamic isotope separation is illustrated in Fig. 51.6a. Feed, such as UFe, diluted with light gas, H2 or He, to a total pressure -2.5 kPa, is fed through a slit-shaped... 

Other processes There are also other processes like the aerodynamic nozzle processes that also use centrifugal forces to separate molecules from UEg molecules but in this case the UFg is transported by hydrogen gas through a narrow static nozzle. The historic EMIS (electromagnetic isotope separation) that operates like a large magnetic sector mass spectrometer uses UCI4 as its feed material has also been used.

This text is concerned primarily with methods used on a large industrial scale. Electrolysis, distillation, and chemical exchange, which are useful primarily for separating deuterium and isotopes of other light elements, will be described in Chap. 13. Diffusion methods, the gas centrifuge, and aerodynamic methods, which are used primarily for uranium but are applicable also to other heavy elements, will be described in Chap. 14. 

Numerous other schemes for separating isotopes in flowing gas streams have been conceived and subjected to small-scale test, but none has appeared sufflciently promising to enlist the major development support given the nozzle and UCOR processes. Summary descriptions of other aerodynamic processes are in references [T2] and [M2].
