6. Laser processes

Processes using lasers are already described in [BN 3 601] , so only a brief description is given here. Two processes have been developed. The first, which has been scaled up to the size of a pilot plant, is the SILVA process, which uses selective interaction between uranium atoms and laser radiation. The second, which has not progressed beyond the laboratory stage, uses selective interaction between the UF 6 molecule and infrared lasers.

6.1 SILVA process

The principle is the selective ionization of uranium vapor. The electronic levels of a 235 U atom are slightly shifted relative to...
