The possibility of multicomponent mixtures separation at thermal heating, ionization and plasma rotation in relation to the spent nuclear fuel (SNF) is shown. At thermal heating it is possible to allocate up to 75% of impurities of fission products (FP), after which the SNF contains oxides of zirconium, niobium and lanthanides. At the stage of ionization it is impossible to deduce the lanthanide oxides, but it is possible to remove partially the oxides of zirconium and niobium. Further removal of impurities will occur in rotated plasma. Under certain conditions heavy ions will get to lateral surface of vacuum chamber, and the light ones will move along the magnetic field lines and precipitate on the collector. The molecular plasma has energy cost to excitation of vibrational and rotational degrees of freedom, dissociation. As simulation media it is advisable to use non-radioactive isotopes of spent nuclear fuel oxides.
