4328423 Canister arrangement for storing radioactive waste
any contaminated acid by electrodialysis, such as removing vanadium and uranium in recoverable form from contaminated phosphoric acid, while producing food grade phosphoric acid in the process. Additionally, simple metals may be removed from mine waste liquids (from leaching), chlorine can be produced from a chloride containing salt, and chromium can be removed from chromium contaminated water by electrolysis. Milling sludge can be treated to form water, caustic, and acid, and mineralized water can be treated to form de-mineralized water, by subjecting the feed liquids to electrodialysis.
4328423 CANISTERARRANGEMENTFOR STORING RADIOACTIVE WASTE D K Loreno, assigned to The United States of America as represented by the United States Department of Energy
The subject invention relates to a canister arrangement for jointly storing high level radioactive chemical waste and metallic waste resulting from the reprocessing of nuclear reactor fuel elements. A cylindrical steel canister is provided with an elongated centrally disposed billet of the metal lit waste and the chemical waste in vitreous form is disposed in the annulus surrounding the billet.

4329179 METHODFORENCAPSULATING ARSENIC-CONTAMINA’IED WASTES
A cw chemical laser which uses processed radioactive waste to produce active atoms from a chemically inactive gas before being mixed with another molecule such as hydrogen or deuterium is disclosed. This laser uses no toxic or corrosive fuels and does not require any electrical or other type of auxiliary power supply. The energy released by the radioactive material is used to produce the active atoms such as fluorine. This is accomplished by using the radiation products from processed radioactive waste to dissociate the inert gas in the plenum of the laser. The radioactive material is held in the passageway walls of a device similar to a heat exchanger. The exchanger device may be located in the gas generator section of a chemical laser. The inactive gas is passed through the exchanger device and while passing through it the radiation from the radioactive material dissociates the gas, producing a concentration of free active atoms. This active atom generator then feeds the nozzle bank or mixing section of a laser to produce a lasing action.

A method for encapsulating an arseniccontaminated waste material, e.g. spent guard bed material, in a concrete formed by mixing the waste material with a tricalciurn aluminate-free hydraulic cement, e .g . aluminous cement, and water. The resulting mixture is allowed to harden producing a concrete product which is highly sulfate and acid resistant. By being sulfate resistant, ettringite is not formed even after prolonged periods of exposure thereby insuring the structural integrity of the concrete product which allows it to be used as a permanent landfill material without risk of the arsenic being leached therefrom by contacting water. Aggregate, e.g. sand and/or silica flour may be added, and the mixture can be agitated an&or exposed to steam during curing ii
