“…15 The radionuclide I-129 is a U-235 fission product with a long half life of 1.6 × 10 7 years. Previously it has only been measured successfully in the Sludge Batch 4 and 5 (SB4, SB5) Waste Acceptance Product Specifications (WAPS) studies 9,11 and SB5 Acceptance Evaluation 16 , where its concentration was reported.…”

“…It was first measured successfully in the SB4 Waste Acceptance Product Specifications (WAPS) studies 9 and the Sludge Batch (SB5) Acceptance Evaluation. 17 Earlier reported concentrations for sludge batches are based on the WCS database. For I-129 the average measured from four aliquots of the sludge slurry was 5.31 × 10 -3 µCi/g of total dried solids or 3.01 × 10 -3 wt%.…”

Presented in this report are radionuclide concentrations required as part of the program of qualifying Sludge Batch 9 (SB9) for processing in the Defense Waste Processing Facility (DWPF). The SB9 material is currently in Tank 51 and has been washed and prepared for transfer to Tank 40. The acceptance evaluation needs to be completed prior to the transfer of the material in Tank 51 to Tank 40. The sludge slurry in Tank 40 has already been qualified for DWPF processing and is currently being processed as Sludge Batch 8 (SB8). i The radionuclide concentrations were measured or estimated in the Tank 51 SB9 Washed Qualification Sample prepared at Savannah River National Laboratory (SRNL). This sample was prepared from a three liter sample of Tank 51 sludge slurry (HTF-51-15-81) taken on July 23, 2015. The sample was delivered to SRNL where it was initially characterized in the Shielded Cells. ii Under the direction of Savannah River Remediation (SRR) it was then adjusted per the Tank Farm washing strategy as of October 20, 2015. iii This final slurry now has a composition iv expected to be similar to that of the slurry in Tank 51 after final preparations have been made for transfer of that slurry to Tank 40.
