Analysis of Sludge Batch 4 (Macrobatch 5) for Canister S02902 and Sludge Batch 5 (Macrobatch 6) for Canister S03317 DWPF Pour Stream Glass Samples

Analysis Of DWPF Sludge Batch 7a (Macrobatch 8) Pour Stream Samples

“…Similar surface films have been observed on the surfaces of previous pour stream samples 17,18 and have been attributed to salt deposits. There did not appear to be a surface film on the SB7a PS#3 sample and the bulk of the sample was black and shiny.…”

Examination Of Sulfur Measurements In DWPF Sludge Slurry And SRAT Product Materials

“…The second observation concerns the rinsates from SB5 and SB6 pour stream glass samples that have been positive for SO 4 2-thus indicating there is S in the melter that is not being incorporated into the glass matrix or forming on the glass surface upon cooling. 13,14 The latter was observed throughout DWPF cold runs. …”

Analysis of DWPF Sludge Batch 6 (Macrobatch 7) Pour Stream Glass Samples

“…i Noble metal inclusions have been observed in previous pour stream samples, including SB4 and SB5. 16 Ru was also detected via XRD in SB6 PS#1 as shown in Figure 3-1. No crystalline phases were detected in SB6 PS#2 and #3.…”
