Phase I (FY01 – 2Q, FY09):
CH Drums (~30,500 drums or ~ 6,000 m3)
Emptied 7 TRU Pads (Pads 7 -13)
Exceeded the original target of 30,000 drums for the TRU Drum Program
Lessons learned incorporated into the Phase II Process

200 m3 of Very Difficult Waste
• High Gamma Emitting Wastes – NDA issues• Concrete casks from SRNL• Silver Saddles from F- & H-Canyons
• High Curie Content Wastes – over WIPP and/or NC limits • Mound and Los Alamos wastes on Pad 1
• Highly Contaminated Wastes – up to 400 million dpm alpha• Stainless steel boxes from H-Canyon Hot Sample Aisle• MSM from 235-F• One-pack plywood boxes from HBL
• Waste with Integral Lead Shielding – NDA and NDE issues• Stainless steel boxes from H-Canyon Hot Sample Aisle
• Oversized RH Debris – size reduction needed

SummarySummary
Worker Safety Highest Priority
30,000 Drum Inventory Complete
Multiple Size Reduction/Remediation Facilities Needed to Complete the Remaining Legacy Inventory
Significant Technical Challenges Remain
Overall Project Still in Early Phase of Execution
Progress to Date Is a Little Behind Plan
