Characterization of a Washed 241-C-106 Sludge Sample

An Envelope D Tank 241-C-106 sample was characterized for solids, elemental, and radioactive isotope content. The work was done by the Savannah River Technology Center (SRTC) to support the Hanford River Protection Project (RPP). The sludge from Hanford Tank 241-C-106 is high level waste that is to be included in the first ten years of processing by the RPP Waste Treatment Plant (WTP). The sample was a composite of caustic-leached and washed sludge from previous work at the Pacific Northwest National Lab (PNNL). Sludge analysis results were found to compare well with those of previous researchers analyzing leached samples from Tank 241-C-106. Composition of the liquid accompanying the sample was also measured
