Subject irradiated nuclear fuels

One important point to consider if ILs are to be used in the nuclear fuel cycle is their stability against radiation. Allen et al. have subjected imidazolium ILs to a, (1, and y radiation and studied their stability vs irradiation type and dose [266], These preliminary results suggest that IL stability is similar to that of benzene, but much higher than that of mixtures of tributylphosphate and kerosine under similar irradiation conditions. That is, imidazolium ILs are rather radiation resistant and no significant decomposition was reported. 

Uranium is converted by CIF, BiF, and BrP to UF. The recovery of uranium from irradiated fuels has been the subject of numerous and extensive investigations sponsored by atomic energy agencies in a number of countries (55—63). The fluorides of the nuclear fission products are nonvolatile hence the volatile UF can be removed by distiUation (see Nuclearreactors Uraniumand uranium compounds).
