Method for calcining nuclear waste solutions containing zirconium and halides

Patent ·
OSTI ID:6358387

A reduction in the quantity of gelatinous solids which are formed in aqueous zirconium-fluoride nuclear reprocessing waste solutions by calcium nitrate added to suppress halide volatility during calcination of the solution while further suppressing chloride volatility is achieved by increasing the aluminum to fluoride ratio in the waste solution prior to adding the calcium nitrate.
