Abstract

The flow rates and pipeline pressures required to deliver high-level waste (HLW) slurries to the planned Waste Treatment Plant depend in part on the quantities, sizes and densities of the particles in the waste sludges. A laboratory program has been performed to provide more firmly grounded information regarding these properties for seven HLW feed tanks, namely Tanks AW-103, AY-101, AY-102, AZ-102, C-104, C-107, and SY-102. The program consisted of eight interdependent efforts. They were: (1) Assess the accuracy and comparability of light scattering particle size distribution (PSD) analysis in the laboratory used for routine analysis of tank wastes (the 222-S Laboratory, operated by Fluor Hanford, Inc.) and an independent laboratory (the 325 Building Laboratory, operated at the Pacific Northwest National Laboratory by Battelle Memorial Institute) by parallel determinations on the size distributions of two certified standards. Also assess the possible effects of instrumental parameter settings on the values returned. (2) Prepare representative composite samples of seven HLW slurries for determination of PSD. (3) Assess the comparability of the same two instruments as a function of instrumental parameter adjustments by parallel particle size determinations of the sludges from three HLW tanks. (4) Use the 2224 particle size analyzer to determine themore »« less

CHARACTERIZATION OF A PRECIPITATE REACTOR FEED TANK (PRFT) SAMPLE FROM THE DEFENSE WASTE PROCESSING FACILITY (DWPF)

Technical Report Crawford, C.; Bannochie, C.

A sample of from the Defense Waste Processing Facility (DWPF) Precipitate Reactor Feed Tank (PRFT) was pulled and sent to the Savannah River National Laboratory (SRNL) in June of 2013. The PRFT in DWPF receives Actinide Removal Process (ARP)/ Monosodium Titanate (MST) material from the 512-S Facility via the 511-S Facility. This 2.2 L sample was to be used in small-scale DWPF chemical process cell testing in the Shielded Cells Facility of SRNL. A 1L sub-sample portion was characterized to determine the physical properties such as weight percent solids, density, particle size distribution and crystalline phase identification.

In-Tank Elutriation Test Report And Independent Assessment

Technical Report Burns, H.; Adamson, D.; Qureshi, Z.; ...

The Department of Energy (DOE) Office of Environmental Management (EM) funded Technology Development and Deployment (TDD) to solve technical problems associated with waste tank closure for sites such as Hanford Site and Savannah River Site (SRS). One of the tasks supported by this funding at Savannah River National Laboratory (SRNL) and Pacific Northwest Laboratory (PNNL) was In-Tank Elutriation. Elutriation is the process whereby physical separation occurs based on particle size and density. This report satisfies the first phase of Task WP_1.3.1.1 In-Tank Elutriation, which is to assess the feasibility of this method of separation in waste tanks at Hanford Sitemore »« less

Feasibility Study on Using Two Mixer Pumps for Tank 241-AY-102 Waste Mixing

Technical Report Onishi, Yasuo; Wells, Beric

The current waste retrieval plan at Hanford calls for using two mixer pumps to mix the waste stored in double-shell Tank 214-AY-102. The objective of this evaluation was to determine whether two rotating 300-hp mixer pumps placed 22 ft (6.7 m) off-center in the tank could adequately mix the AY-102 waste. The tank currently contains high-level waste that is 248 inches (6.3 m) deep, comprising 62 inches (1.58 m) of sludge and 186 inches (4.72 m) of supernatant liquid (Galbraith et al. 2002). Based on the available data, AY-102 waste properties were determined, including the densities of liquid and agglomeratedmore »« less

Discovery of the First Leaking Double-Shell Tank - Hanford Tank 241-AY-102

Conference Harrington, Stephanie; Sams, Terry

Full text - Long Abstract. A routine video inspection of the annulus region of double-shell tank 241-A Y-102 in August of 2012 indicated the presence material in the annulus space between the primary and secondary liners. A comparison was made to previous inspections performed in 2006 and 2007. which indicated that a change had occurred. The material was observed at two locations on the floor of the annulus and one location at the top of the annulus region where the primary and secondary top knuckles meet (RPP-ASMT-53793). Subsequent inspections were performed. leading to additional material observed on the floor ofmore »« less

Results of Characterization and Retrieval Testing on Tank 241-C-109 Heel Solids

Technical Report Callaway, William

Eight samples of heel solids from tank 241-C-109 were delivered to the 222-S Laboratory for characterization and dissolution testing. After being drained thoroughly, one-half to two-thirds of the solids were off-white to tan solids that, visually, were fairly evenly graded in size from coarse silt (30-60 μm) to medium pebbles (8-16 mm). The remaining solids were mostly strongly cemented aggregates ranging from coarse pebbles (16-32 mm) to fine cobbles (6-15 cm) in size. Solid phase characterization and chemical analysis indicated that the air-dry heel solids contained ≈58 wt% gibbsite [Al(OH){sub 3}] and ≈37 wt% natrophosphate [Na{sub 7}F(PO{sub 4}){sub 2}·19H{sub 2}O].more »« less
