Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the rheology of the radioactive sludge slurries at the Savannah River Site is necessary in order to ensure that they can be retrieved from waste tanks and processed for final disposal. At Savannah River Site, Tank 42 sludge represents on of the first HLW radioactive sludges to be vitrified in the Defense Waste Processing Facility. The rheological properties of unwashed Tank 42 sludge slurries at various solids concentrations were measured remotely in the Shielded Cells at the Savannah River Technology Center using a modified Haake Rotovisco viscometer.

Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the rheology of the radioactive sludge slurries at the Savannah River Site (SRS) is necessary in order to ensure that they can be retrieved from waste tanks and processed for final disposal. At Savannah River Site (SRS), Tank 42 sludge represents one of the first HLW radioactive sludges to be vitrified in the Defense Waste Processing Facility (DWPF). The rheological properties of unwashed Tank 42 sludge slurries at various solids concentrations were measured remotely in the Shielded Cells at the Savannah River Technology Center (SRTC) using a modified Haake Rotovisco viscometer. Rheological properties of Tank 42 radioactive sludge were measured as a function of weight percent total solids to ensure that the first DWPF radioactive sludge batch can be pumped and processed in the DWPF with the current design bases. The yield stress and consistency of the sludge slurries were determined by assuming a Bingham plastic fluid model.

Available in PDF, EPUB and Kindle. Book excerpt: Savannah River Site (SRS) Tank 51 HLW radioactive sludge represents a major portion of the first batch of sludge to be vitrified in the Defense Waste Processing Facility (DWPF) at SRS. The rheological properties of Tank 51 sludge will determine if the waste sludge can be pumped by the current DWPF process cell pump design and the homogeneity of melter feed slurries. The rheological properties of Tank 51 sludge and sludge/frit slurries at various solids concentrations were measured remotely in the Shielded Cells Operations (SCO) at the Savannah River Technology Center (SRTC) using a modified Haake Rotovisco viscometer system. Rheological properties of Tank 51 radioactive sludge/Frit 202 slurries increased drastically when the solids content was above 41 wt %. The yield stresses of Tank 51 sludge and sludge/frit slurries fall within the limits of the DWPF equipment design basis. The apparent viscosities also fall within the DWPF design basis for sludge consistency. All the results indicate that Tank 51 waste sludge and sludge/frit slurries are pumpable throughout the DWPF processes based on the current process cell pump design, and should produce homogeneous melter feed slurries.

Download or read book A Comparison of Rheology Data for Radioactive and Stimulant Savannah River Site Waste written by and published by . This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The concept for decontamination and retirement of radioactive liquid waste tanks at the Savannah River Plant (SRP) involves hydraulic slurrying to remove most of the settled sludges followed by chemical dissolving of residual sludges. Dissolving tests were carried out with small samples of sludge from SRP Tank 16H. Over 95 percent of the sludge was dissolved by 8 wt percent oxalic acid at 85°C with agitation in a two-step dissolving process (50 hours per step) and an initial reagent-to-sludge volume of 20. Oxalic acid does not attack the waste tank material of construction, appears to be compatible with the existing waste farm processes and equipment after neutralization, and with future processes planned for fixation of the waste into a high-integrity solid for packaging and shipping.
