Although, the extraction of U and Pu from SNF has been developed on an industrial scale, processes that meet Generation IV targets for proliferation resistance have only been demonstrated under laboratory conditions. The technical and economic feasibility of deploying them on an industrial scale has not been established. The fabrication of fuels containing high quantities of MAs and possibly LLFPs will require heavily shielded facilities. The wastes from these new processes have not been studied and will require new treatment systems.
