• Completed removal of 386 Multi-Canister Overpacks containing spent fuel from K Basins
• K Basins fuel MCOs now stored at Canister Storage Building
– 252 Mark IV MCOs
• 6 contain some Mark IA or SPR fuel
• 3 “short-stacked” MCOs
– 133 Mark IA MCOs
– 1 Single-Pass Production Reactor MCO

• Scrap inventory in MCOs
– Approximately 70,000 pounds of scrap
– 66 Mark IV scrap baskets used
• 4 MCOs contain 2 Mark IV scrap baskets
• 4 Mark IV scrap baskets contain some Mark IA or SPR scrap
– 1 Mark IA scrap basket used

• 1-2 additional MCO(s) anticipated for fuel and scrap discovered during sludge removal, some found fuel
– Fuel inventoried as unknown SPR, likely PRTR fuel
– 2+ SPR elements at B/C Reactor burial grounds
– 2 SPR elements and 1 N Fuel element at KW Basin
• Completed welding of >350 Welded N Stamped MCOs
– No defects to date
– Scheduled to complete welding of 383 K Basins MCOs and 18 Shippingport MCOs in Fiscal Year 2005
– 3 MCOs scheduled to be welded in Fiscal Year 2007 to complete planned 2 year sampling/monitoring period; remaining 1-2 MCOs from K Basins will be welded at that time.

Fast Flux Test Facility Fuel
Right: Interim Storage Cask receipt at 200 Area Interim Storage Area
• Off-load of fuel at FFTF into Interim Storage Casks (ISCs) over 2/3 complete. Loaded ISCs stored at 200 Area Interim Storage Area and Plutonium Finishing Plant (PFP).
• Off-load of all remaining FFTF spent fuel, including sodium bonded fuel, into ISCs to resume in July, 2005.
• Transfer of all remaining ISCs from FFTF to 200 Area ISA to complete by March 31, 2006.
• Plans being modified to extend storage of Hanford slightly irradiated fuel, including FFTF slightly irradiated fuel, with other PFP materials.

Oregon State University TRIGA Fuel• Fuel currently contained in 13 drums, which
were buried in 1986 at Low-Level Burial Grounds
• Evaluating funding to retrieve the 13 drums of fuel in Fiscal Year 2006, then overpack, and store the drums in Rad Vaults at the 200 Area Interim Storage Area
