Impact of CST on the Rheological Characteristics of DWPF Melter Feed

Paper Study Evaluations of the Introduction of Small Column Ion Exchange Waste Streams to the Defense Waste Processing Facility

“…The yield stress of the DWPF process slurries could be impacted if the rheological behavior of the CST solids is different than the sludge. 19 Experimental testing would be required to evaluate the impact of using CST that has been ground in a prototypical manner. This evaluation, along with simulant testing, 22 demonstrated that the CPC process could accommodate the MST stream.…”

CST Melter Feed Characterization in Support of the 1999 and 2000 Thermal Fluids Lab Hydragard Testing

“…The third run used no CST. The rheological properties of these three SME products will be characterized and reported in [7]. This data should help to clarify the role of CST on melter feed rheology.)…”

Scix Impact on DWPF CPC

“…8,9 Two 1999 melter feeds, one 35% sludge and 65% frit on an oxide basis, and one 26.7% sludge, 8.3% CST, and 65% frit on an oxide basis, were compared over the range of 39-51 wt% total solids. Rheological properties were nearly identical.…”
