【 摘 要 】

The Defense Waste Processing Facility (DWPF) requested that a radioactive demonstration of the next batch of sludge slurry (Sludge Batch 3) be completed in the Shielded Cells Facility of the Savannah River Technology Center (SRTC). Sludge Batch 3 (SB3) consists of the heel in Tank 51, which included Plutonium (Pu) and Americium/Curium (Am/Cm); sludge slurry from Tank 7 (including sludge transferred into Tank 7 from Tanks 18 and 19); additional Pu transferred from H Canyon; a Neptunium (Np) transfer also from H Canyon; and the remaining Sludge Batch 2 material in Tank 40. Because the current contents of Tank 40 (Sludge Batch 2) have already been qualified, this qualification work did not include the contribution of Tank 40. Documented in this report are: preparation of a SB3 slurry using a Tank 51 sample from June 2003; a demonstration of the DWPF Sludge Receipt and Adjustment Tank (SRAT) cycle using SB3 slurry; a demonstration of the DWPF Slurry Mix Evaporator (SME) cycle using SRAT product; glass fabrication and subsequent chemical durability evaluation using SB3 material; and evaluation of adding formic acid to the SME cycle product.
