Abstract

Method for recovery of actinides from nuclear waste material containing sintered and other oxides thereof and from scrap materials containing the metal actinides using O/sub 2/F/sub 2/ to generate the hexafluorides of the actinides present therein. The fluorinating agent, O/sub 2/F/sub 2/, has been observed to perform the above-described tasks at sufficiently low temperatures that there is virtually no damage to the containment vessels. Moreover, the resulting actinide hexafluorides are not detroyed by high temperature reactions with the walls of the reaction vessel. Dioxygen difluoride is readily prepared, stored and transferred to the place of reaction.

Method for recovery of actinides from refractory oxides thereof using O/sub 2/F/sub 2/

Patent Asprey, L.B.; Eller, P.G.

A method is described for the recovery of actinides present in oxides thereof, which comprises the steps of: a. contacting the oxide material with O/sub 2/F/sub 2/ at temperatures below approximately 25/sup 0/C for a sufficient period of time for substantial generation of the hexafluorides of the actinides to occur; and b. collecting the generated actinide hexafluorides.
Method for fluorination of actinide fluorides and oxyfluorides using O/sub 2/F/sub 2/

Patent Eller, P.G.; Malm, J.G.; Penneman, R.A.

The present invention relates generally to methods of fluorination and more particularly to the use of O/sub 2/F/sub 2/ for the preparation of actinide hexafluorides, and for the extraction of deposited actinides and fluorides and oxyfluorides thereof from reaction vessels. The experiments set forth hereinabove demonstrate that the room temperature or below use of O/sub 2/F/sub 2/ will be highly beneficial for the preparation of pure actinide hexafluorides from their respective tetrafluorides without traces of HF being present as occurs using other fluorinating agents: and decontamination of equipment previously exposed to actinides: e.g., walls, feed lines, etc.
Method for fluorination of actinide fluorides and oxyfluorides thereof using O[sub 2]F[sub 2]

Patent Eller, P.G.; Malm, J.G.; Penneman, R.A.

Method is described for fluorination of actinides and fluorides and oxyfluorides thereof using O[sub 2]F[sub 2] which generates actinide hexafluorides, and for removal of actinides and compounds thereof from surfaces upon which they appear as unwanted deposits. The fluorinating agent, O[sub 2]F[sub 2], has been observed to readily perform the above-described tasks at sufficiently low temperatures that there is virtually no damage to the containment vessels. Moreover, the resulting actinide hexafluorides are thereby not destroyed by high temperature reactions with the walls of the reaction vessel. Dioxygen difluoride is easily prepared, stored and transferred to the desired place of reaction.
Method for the recovery of actinide elements from nuclear reactor waste

Patent Horwitz, E.P.; Delphin, W.H.; Mason, G.W.

A process is described for partitioning and recovering actinide values from acidic waste solutions resulting from reprocessing of irradiated nuclear fuels by adding hydroxylammonium nitrate and hydrazine to the waste solution to adjust the valence of the neptunium and plutonium values in the solution to the +4 oxidation state, thus forming a feed solution and contacting the feed solution with an extractant of dihexoxyethyl phosphoric acid in an organic diluent whereby the actinide values, most of the rare earth values and some fission product values are taken up by the extractant. Separation is achieved by contacting the loaded extractant withmore »« less
