Analytical Results of DWPF Glass Sample Taken During Filling of Canister S01913

Abstract

The Defense Waste Processing Facility (DWPF) began processing Sludge Batch 2 (SB2) in December 2001 as part of Sludge Receipt and Adjustment Tank (SRAT) Batch 208. Sludge Batch 2 consists of the contents of Tank 40 and Tank 8 in approximately equal proportions. The sludge slurry is received into the DWPF Chemical Processing Cell and is processed through the SRAT and Slurry Mix Evaporator Tank. The treated sludge slurry is then transferred to the Melter Feed Tank and fed to the melter. During the processing of each sludge batch, the DWPF is required to take at least one glass sample. This glass sample is taken to meet the objectives of the Glass Product Control Program1 and to complete the necessary Production Records so that the final glass product may be disposed of at a Federal Repository.The DWPF requested analysis of a radioactive glass sample obtained from the melter pour stream during the processing of Macrobatch 3 (MB3) (Sludge Batch 2)2 with Frit 320. A glass sample was obtained while pouring Canister S01913 and was sent to the Savannah River National Laboratory Shielded Cells for characterization. Canister S01913 was the 267th canister poured during vitrification of Sludge Batch 2 (364 canisters of glass were prepared from SB2). The glass sample arrived from DWPF in primary container PC0034. The primary container contained pieces of glass. The glass had been extracted from the sample holder in the DWPF. This report contains the visual observations of the as-received glass sample, results for the density, the chemical composition, the Product Consistency Test and the calculated and measured radionuclide results needed for the Production
