Tank 241-B-203 tank characterization plan

Tank characterization report for single-shell tank 241-B-104

“…A-4. No results were greater than the tank characterization plan notification limit of 100 pglg (Jo 1995b). The upper half of core 88 segment four, both halves of core 89 segment two, both halves of core 89 segment four, and the lower half of core 89 segment 7 exhibited lithium results greater than the analytical detection limit (see.…”

“…From the two core samples, four primary analyses were performed as directed in the Tank (Jo 1995b). These analyses were differential scanning calorimetry @SC) (to evaluate fuel level and energetics), thermogravimetric analysis (TGA) (to determine moisture content), total alpha activity (to evaluate criticality potential), and flammable gas concentration.…”

“…WHC-SD-WM-ER-552, &v. 0 Push-mode core samples were taken to satisfy the requirements of the Tank Safety Screening Data Quality Objective (Babad and Redus 1994), and the Interim Data Quality Objectives for Waste Pretreafment and VitnJcm'on (Kupfer et al 1994). The sampling and analyses were performed in accordance with the Tank 241-E-104 Tank Charactenm'on Plan (Jo 1995b).…”

“…The only physical analyses required by the tank characterization plan (Jo 1995b) were TGA and DSC. Density, percent solids, particle size, and rheology were neither requested nor performed.…”

“…Lithium bromide was added to the HHF to act as a tracer. Analyses for lithium and bromide were performed in accordance with the tank charactehtion plan (Jo 1995b) to detect contamination of the waste samples with HHF. All subsegments and both drainable liquid samples from each core were analyzed for lithium.…”
