A Comparison of Rheology Data for Radioactive and Stimulant Savannah River Site Waste
This document reviews radioactive and simulant rheology data on SRS waste slurries. Simulant sludge slurries have been prepared at Optima: Tank 51 for Sludge Batch 1A (SB1A) and trimmed for Sludge Batch 1B (SB1B), at USC-Columbia: Tank 8 and Tank 40 for Sludge Batch 2 (SB2), and at Clemson Environmental Technology Laboratory (CETL): SB2, Sludge Batch 3 (SB3), and several generic simulants. Various radioactive waste tank slurry samples have been analyzed for rheology in the SRTC Shielded Cells during the past 25 years. More recently, some rheological measurements have been made on the DWPF qualification samples for new sludge batches or on special samples pulled to help with resolution of processing issues. This document attempts to make comparisons of rheological data for systems where there were both some radioactive slurry data and some potentially similar simulant slurry data. The Approach section describes the basic data types encountered, e.g. sludges, Sludge Receipt and Adjustment Tank (SRAT) products, and Slurry Mix Evaporator (SME) products. The last are equivalent to melter feeds. This is followed by a discussion of rheometry and the Bingham Plastic fluid model. This model has been used to reduce rheological data on SRS waste slurries over the past twenty years.
