Saltstone Processing
• Processed 3.7M gallons of salt solution total• Processed 1.4M gallons since start of current
campaign in March 2007• Processing Rate – 120K gallons / wk• Vault 2 Under Construction
6
Salt Waste Processing Facility
• 98M Gallons Salt Solution to be processed• Full Construction Authorization (CD-3)• Transition to Radioactive Operation - May 2013
7
Salt Disposition Integration Project
• Prepare initial macrobatch feed for SWPF• Ready to feed SWPF by a rate of:
– 3.75M gallons / yr – first year – 6M gallons / yr – normal rate
• Ready to process 220K gal/wk from SWPF to Saltstone• Ready to process Strip Effluent and MST Sludge Solids
from SWPF to DWPF

HLW Processing Overview
• 2696 Canisters Produced (thru March 31)• 2.82 M Gallons transferred from HTF • 97 Canisters – FY 09 (thru March 31)• Processing Sludge Batch 5 thru May 2010• Melter 2 – Operational Since March 2003• Melter 3 – Ready as Spare• Melter 4 - Vessel and Frame contract awarded
• K3 Refractory – Manufacturing In progress• Components – Under construction • Assembly completion date – November 2013

Issues and Challenges
• Tank Closure• Canister Fissile Loading – Processing limitations
– 897 g/m3 – Sludge Batch 5 limited to 33 wt % waste loading
• Construction and Startup of SWPF• Total Canister Production• Availability of Federal Repository
