Waste Management. Savannah River Laboratory quarterly report, April--June 1976
Long-term waste management studies reported on are decontamination of supernate, dissolution of glass waste forms, and nephelometric determination of sulfate. Laboratory tests with 100-liter samples of actual waste supernate showed that cation exchange resins remove /sup 137/Cs, /sup 90/Sr, and plutonium with decontamination factors of 4.5 x 10/sup 5/, 5 x 10/sup 3/, and 3 x 10/sup 2/, respectively. Laboratory tests showed that radionuclides can be recovered from glass waste forms by dissolving the glass in HNO/sub 3/. A program to improve sulfate measurement for waste management and environmental studies has been concluded with development of a nephelometric method for determining 0.5 ppM or less sulfate in aqueous solutions. Interim waste management studies reported on are sludge dissolution rates, low-pressure sludge removal, and salt sealing of and salt removal from waste tank cracks. Tests with sludge from Tank 16 indicate that, under the same conditions, oxalic acid and ''Decon'' 4518 are about equally effective for dissolving most of the sludge. Preliminary semiworks tests of the slurrying capability of a developmental recirculating pump indicated an effective cleaning radius of approximately 20 feet with a mixture of kaolin and water simulating sludge and supernate. Experiments with simulated waste indicate that salt does not completely seal stress-corrosion cracks in waste tanks in less than one month, under present conditions in the annulus.
