Remediation and closure of the Single-Shell Tanks (SSTs) located on the Department of Energy's Hanford Site may depend on innovative waste removal, pretreatment and disposal technologies. This report describes preliminary studies conducted to support pretreatment processing of SST waste. This presentation looks specifically at the following types of activities: development, synthesis and characterization of a nonradioactive simulated SST waste; preliminary sequential dissolutions of simulated tank sludge; and thermochemical reduction of nitrate, a major component in SST waste. 7 refs., 4 figs., 6 tabs.
