Initial SB4 Melt Rate Furnace Testing (U)

Sludge Batch 4 Baseline Melt Rate Furnace and Slurry-Fed Melt Rate Furnace Tests With Frits 418 and 510 (U)

“…The SMRF runs were recorded in notebook WSRC-NB-2004-00123 and performed per Run Plan SRNL-PSE-2007-00114. 10 However, a shift in the melt rate of the standard used does not allow comparison with these results and the previous SB3/Frit 418 MRF result. The frits that indicated a possible positive impact on SB4 melt rate were Frits 510 and 511.…”

Accelerated Processing of SB4 and Preparation for SB5 Processing at DWPF

“…4 This finding was equally important since initial SB4 melt rate testing had little success in finding a frit that would provide melt rate that was considered acceptable for DWPF processing. 5,6 However, shortly after SRNL recommended the use of Frit 503, whoich appeared to have a throughput equivalent to that seen for the Sludge Batch 3 (SB3)-Frit 418 system 4 , the LWO had to change the final composition of SB4. A confirmation sample of SB4 taken from Tank 51 near the end of sludge preparation indicated rheological properties that exceeded the transfer pump criteria.…”
