Abstract: There is disclosed a system for dispensing granular material, comprising: a nozzle attached to a granular filler configured to couple with a trefoil filling port attached to a can for hot isostatic pressing, wherein the nozzle opens and closes via a rotary actuation. In an embodiment, the system comprises a single fill port design, such as one having a concentric, tube-in-tube design. There is also disclosed a method of filling a container with a granular material, by connecting a filling nozzle to a filling port, opening/closing the filling nozzle, attaching the filling nozzle to the filling port, aligning at least one opening of the filling nozzle with an opening in the filling port; and dispensing granular material into the container.

Abstract: A canister for interim storage and subsequent consolidation of waste materials via hot pressing and comprising at least one ion exchange material. The canister is configured to house the ion exchange material after it is exchanged with a contaminating ion without releasing the contaminating ion and to consolidate waste materials via hot-isostatic pressing. A method comprising contacting a fluid waste with an ion exchange material.

Abstract: A method for treating a fluid waste, comprising adding one or more process additives to the fluid waste in an amount sufficient to change the wasteform chemistry is disclosed. The addition step may be chosen from adding a dispersant or a deflocculant an additive to decrease the reactive metal components, to bind fission products and decrease volatilization of toxic or radioactive elements or species during thermal treatment, or to target and react with the fine particle size component of the waste to decrease dusting and immobilize components in a durable phase. After mixing the fluid waste with the described additives the waste is eventually hot-isostatic pressing, to form a durable and stable waste form.

Abstract: A composition to immobilize nuclear containing waste containing at least one radioactive element or alloy of uranium, graphite, magnesium, and aluminum is disclosed. The composition comprises at least one mineral phase forming element or compound for reacting with the at least one radioactive element or alloy. The composition further comprises at least one glass-forming element or compound to form a glass phase that will incorporate waste radioisotopes and impurities that do not react with the mineral phase forming element or compound. A method of using the disclosed composition to immobilize the nuclear containing waste into a solid wasteform is also disclosed.

Abstract: There is disclosed a vertical vibratory thermal treatment system, comprising a heating section for thermally treating material, a retort section that is located within or connected to the heating section and includes at least one elevator system for vertically moving the material to the heating section. The disclosed elevator system is isolated from other parts of the thermal treatment section by an enclosure thereby allowing for flexibility and simplicity in the design of the retort section. There is also disclosed a method of treating materials, including hazardous or radioactive materials, such as a powder, sand, granule, gravel, agglomerate or other form of particle or combinations thereof, using the system described herein.

In an embodiment, the canister comprises at least one ion exchange material, and is configured to: house the ion exchange material after it is exchanged with a contaminating ion without releasing the contaminating ion; and consolidate via hot-isostatic pressing. There is also disclosed a contacting a fluid waste with an ion exchange material, wherein the ion exchange material is located in a canister; evacuating the canister; and hot isostatically pressing (HIP) the canister until it collapses under HIP conditions.
