Sludge Batch 2/3 Blend SRAT Cycle in the SRNL Shielded Cells

PDF Version Also Available for Download.

Description

The work conducted for this report was done to determine whether any processing problems could be anticipated with the blended material from Tank 40 and 51. The purpose of this report is to document the results of a SB2/3 blend Sludge Receipt Adjustment Tank (SRAT) cycle performed at the Savannah River National Laboratory (SRNL) Shielded Cells Facility (SCF). The following conclusions are drawn from this work: the SB2/3 blend supernate has a surface tension significantly higher than SB2 simulants and close to that of water; SB2/3 blend rheology is slightly more viscous and visually more cohesive than a SB3 sample ... continued below

Description

The work conducted for this report was done to determine whether any processing problems could be anticipated with the blended material from Tank 40 and 51. The purpose of this report is to document the results of a SB2/3 blend Sludge Receipt Adjustment Tank (SRAT) cycle performed at the Savannah River National Laboratory (SRNL) Shielded Cells Facility (SCF). The following conclusions are drawn from this work: the SB2/3 blend supernate has a surface tension significantly higher than SB2 simulants and close to that of water; SB2/3 blend rheology is slightly more viscous and visually more cohesive than a SB3 sample alone; SRAT cycle processing of a SB2/3 blend was accomplished with no significant issues. Nitrite was destroyed at 140 per cent of acid stoichiometry. Hydrogen generation was well within DWPF limits. Nitrous oxide generation was well within DWPF limits. Considerable soluble uranium was measured in the SRAT product, likely as a result of the final pH of the SRAT product. SB2/3 blend SRAT product is less viscous than the starting feed with both the consistency and yield stress below the recommended DWPF operating region. The demonstration of simulated DWPF SRAT cycle processing of a radioactive SB2/3 blend based upon the expected tank volume ratios, at the time of the experimentation, in the SRNL Shielded Cells was accomplished successfully.
