| Summary: | 3,000 mg/L nickel in the untreated sludge were reduced to additives in the Portland cement based treatment systems. and nickel concentrations, leachability, physical based systems for a range of binder-to-waste ratios, and be evaluated over long curing periods. Attempts at binder interactions, and the suitability and effectiveness of Compressive Strength, regulatory compliance, and risk Department of Energy facilities have generated large volumes estimating the extent of sorption and other immobilization extract of the solidified waste form. immobilization in terms Of MacMullin number and Unconfined less than 10 mg/L uranium and 30 mg /L nickel in the TCLP mechanisms were made using dry and hydrated cement matrices. of mixed wastes with hazardous and radioactive components. optimal substitutions of cement with additives. This was over three binder-to-waste ratios. The 900 mg/L uranium and Portland cement based systems with flyash, silica fume and reduction were evaluated in the solid waste forms ranging representative of the actual Oak Ridge K-25 pond waste. Research missions in nuclear energy conducted by the U.S. Screening tools such as the short term slurry tests were used sodium sulfide as additives were studied. Porewater uranium Solidification/Stabilization (S/S) chemistry, complex waste- the S/S system components to design solid waste form mixes to The treatability was investigated with a simulated waste this research which focused on better understanding the to ascertain the behavior of the contaminants in the cement Uranium and nickel are the primary contaminants of concern in used in combination with the Acid Neutralizing Capacity of |
