Approximate waste concentrations presented are typical of waste produced by Purex, TBP-25, STR, Darex, and SIR processes with fuels of current design. Evaporation of acidic waste provides the maximum reduction in volume to be secured by a simple treatment. Controlled heating of the dry residues further reduces the mass of the solid residue. Neutralization of the acidic wastes produces solid precipitates (ferric, aluminum, or zirconium hydroxide) which settle slowly and are difficult to filter; calcium hydroxide gave precipitates which filter more readily than sodium hydroxide-neutralized material. A flocculating agent improves settling rates, more for the calcium hydroxide neutralized material than for the sodium hydroxideneutralized. If neutralization is desirable before evaporation, the neutralized waste can be satisfactorily evaporated in a system which prevents bumping. (auth)
