Latest Patents

Low Temperature Route to Uranium Nitride. This invention describes a method for preparing actinide nitride fuel for nuclear reactors. It converts actinide oxides, optionally combined with zirconium oxide, into fluoride salts using a hydrogen fluoride source. The salts are then heated to remove water and treated in a nitrogen atmosphere to form nitrides. A final heating step under vacuum or an inert atmosphere converts the nitrides to mononitrides.

Uranium Enrichment Using Microorganisms. This invention presents methods for separating uranium and other actinide isotopes with microorganisms, including metal- or sulfate-reducing bacteria. The microorganisms reduce the actinide and can produce a precipitate enriched in the lighter isotope compared with the starting material. The precipitate may be collected, re-oxidized, and processed through additional enrichment rounds. The patent also describes approaches that do not require precipitation, cell-free isotope-separation systems, and compositions such as enriched uraninite.
