5 Saltstone Processing Processed 3.7M gallons of salt solution total Processed 1.4M gallons since start of current campaign in March 2007Processing Rate – 120K gallons / wkVault 2 Under ConstructionBackground – just in case it comes up –March 5, DDA processing initiated (Deliquification, dissolution, and adjustment)Late March 2007 – legal appeal filed, Saltstone processing suspended.October 2007 – Legal appeal resolved. Processing resumes.Vault M gallons grout / 192 CiVault M gallons grout / 134,000 Ci total inventoryOriginal design – Ci/galCurrent design – 0.1 to 0.2 Ci/galOriginal Design capacity K gallons / weekRecent failure of grout pump hose - expect to return to Tank 50 processing by approximately mid-April.Vault 2 construction completion in July 2010Vault 2 – two concrete tanks with a total useful volume of 667,000 ft3. Equivalent to about 3 cells of the old vault design. About 35 weeks operating volume.

Started mechanical cleaning in two type IV waste tanks in F Area (sand mantis to remove zeolite resin mounds from CRC units) Two type IV tanks previously closed in F AreaSWPF – Current operational date of May Parsons is responsible for the design, construction, and first year of operation of the facility.High Al Sludge – higher viscosity melt – lower heat transfer rate – lower melt rate – lower canister production rate - investigating new frit formulations, improvements to existing melter operationTotal Canister Production – System Plan Rev canisters (with mitigation – new melter technology, higher waste loading, with Al removal)Maintaining all future canisters below 897 g/m additional canistersNo mitigation (no new melter technology or higher waste loading) additional canisters - need to confirm numbers2244 canisters stored in GWSB#1 (99.6% of capacity)449 canisters stored in GWSB#2 (19.2% of capacity)GWSB #3 - needed by FY Is in the planning baselinePlanning Basis was to start shipments in FY 17FY17 – 130 canisters/ yearFY canisters / yearFY19 – 500 canisters / year
