Atomic Vapor Laser Isotope Separation

We present several results from our experiments on the separation processes on Atomic Vapor Laser Isotope Separation (AVLIS). Whole separation process is divided into four major subprocesses for convenience, ie. evaporation process for generating atomic beam, photoreaction process for ionizing isotopes selectively by resonant multistep photoionization method, ion extracting process for recovering isotopic ions from laser induced plasma, and light propagation process for propagating laser beams in the optically deep atomic medium with the interaction between photons and specific elements. We have achieved the separative power of 14kgSWU/y and the maximum specific separative power of 1.24ngSWU/P/cm3 and energy efficiency of 12.3gSWU/kWh for producing low enriched uranium. (author)
