ARP – Actinide Removal Process – removal of actinides (AN #89 through A# Thorium, Protactinium, Uranium, Neptunium, Plutonium, Americium, Curium etc) and Strontium
MCU – Modular Caustic Side Solvent Extraction Unit – Removal of Cs 137
ARP / MCU - Radioactive operations – spring 2008 – one year of operation to date – will run until SWPF comes online .
About 365,000 gallons have been fed to ARP / MCU to date (about 4000 gallons per batch).
Processing flow rate is 4 gpm.
Complex system - note that ARP / MCU is in H Tank Farm

5. 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
Background – 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 Ci
Vault M gallons grout / 134,000 Ci total inventory
Original design – Ci/gal
Current design – 0.1 to 0.2 Ci/gal
Original Design capacity K gallons / week
Recent failure of grout pump hose - expect to return to Tank 50 processing by approximately mid-April.
Vault 2 construction completion in July 2010
Vault 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.

6. Salt Waste Processing Facility
98M Gallons Salt Solution to be processed
Full Construction Authorization (CD-3)
Transition to Radioactive Operation - May 2013
CD-3 received late FY08
Schedule contingency – 124 weeks (31 months) to January 2016

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

8. 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 Vessel and Frame contract awarded
K3 Refractory – Manufacturing In progress
Components – Under construction
Assembly completion date – November 2013
Over 10.5 Million Pounds of HLW Glass
18.4 Million Ci
canisters poured by Melter 1
canisters poured by Melter 2
Planning basis – High Fe sludge – 250 canisters per year / High Al sludge – 186 canisters per year.
Sludge Batch 5 – low temperature Aluminum dissolution conducted for this batch
Sludge Batch 6 processing in progress – will also undergo LTAD
System Plan Rev 15 – Sludge processing complete in FY30

9. 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
Recently completed acid cleaning in two type I waste tanks in F Area. 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 Area
SWPF – 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 operation
Total 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 canisters
No mitigation (no new melter technology or higher waste loading) additional canisters - need to confirm numbers
2244 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 baseline
Planning Basis was to start shipments in FY 17
FY17 – 130 canisters/ year
FY canisters / year
FY19 – 500 canisters / year
