Improvement on gaseouscentrifuge technology,use of heat.
Laser Separation
Separation of Isotopes by Laser Excitation (SILEX)Australian project that will be commercially
ready by 2012.
Laser Separation
Atomic vapor laser isotope separation(AVLIS)Photoionization of target isotope
Molecular laser isotope separation(MLIS)Photolysis of Uranium Hexafluoride to
Uranium Pentafluoride
Other Techniques
Aerodynamic processes
Becker jet nozzle
○ Vortex tube
Other Techniques
Electromagnetic Isotope Separation
Ionized Uranium is deflected to coll-ection targets inmagnetic field.
Other Techniques
Chemical Methods
Slightly different reactions of U-235, U-238 to Redox
Other Techniques
Plasma Separation
Selective energizing of U-235 with plasma that contains a mix of ions.
