2. Savannah River Downblending Program for Surplus, Non-Pit Plutonium BACKGROUND Current K-Area Interim Surveillance (KIS) Glovebox/VaultCapabilities: Performing Non-Destructive Examination (NDE) of 9975s and 3013 containers Performing Destructive Examination of 3013 containers, sampling and repackaging of oxide into can-bag-can, and repackaging plutonium oxide into 9975 shipping container Performing nuclear material verification measurements DOE-SR requested K-Area in FY14 to make preparations to downblend Pu oxide DOWNBLENDING PROJECT JUSTIFICATION Downblending Pu oxide reduces safeguards attractiveness level Pu oxide downblending previously demonstrated at SRS, Hanford, Rockflats Prepares Pu oxide for disposition to WIPP or final repository Supports removal of plutonium from State of South Carolina 2
