【 摘 要 】

The Defense Waste Processing Facility began processing Sludge Batch 2 in December of 2001. Since the introduction of the first complete process batch from Sludge Batch 2, processing issues have been observed in the Sludge Receipt and Adjustment Tank , Slurry Mix Evaporator, Melter Feed Tank and the melter. Testing was done to determine what effect different levels of uranium would have on the processing of Sludge Batch 2 in the Defense Waste Processing Facility Chemical Processing Cell. Two levels of uranium were added to Sludge Batch 2 simulant, 7.5 percent wt uranium solids and 15 percent wt uranium solids and were tested along with the simulant with no uranium added. The testing started with titrations of uranyl nitrate solutions. Titrations were then performed on slurries of Sludge Batch 2 simulant, and the simulant with two levels of uranium added to determine whether uranium would increase the acid demand during processing.
