Fourty-five day safety screen results for Tank 241-C-107, push mode, cores 68 and 69

摘要

Reported are the safety-screening analytes required by the C-107 tank characterization plan. Also included are copies of the differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) scans. Two core samples from tank C-107, obtained by the push-mode core sampling method, were received, extruded, and analyzed by the 222-S Laboratories. Drainable liquid was analyzed at the segment level for a separable organic layer, energetics by DSC, and percent water by TGA. Sludge samples were analyzed at the half-segment level by DSC, TGA, and for total alpha activity. No safety-screening notification limits were exceeded on any samples.
