Tank characterization report for single-shell tank 241-U-109

“…The highest one-sided 95 percent confidence interval upper limit on the mean was 493.4 Jlg (dry weight), slightly above the safety screening and organic complexant safety DQO decision threshold. However, this result was attributed to variability in the data (Baldwin 1996a). …”

“…0 'Agnew et al (Baldwin 1996a) T h e HTCE predictions have not been validated and should be used w i t h caution.…”

“…The drainable liquid sample from segment 3 of core 124 was diluted with acid before ICP analysis. An ICP analysis for aluminum, chromium, and sodium was also performed on a water-leached aliquot from each of the core composite samples, and on the segments that were selected for the secondary historical analyses as most representative of their waste type based on the key analyte analysis (Baldwin 1996a). Additional analytes required by the historical model evaluation DQO included bismuth, calcium, iron, manganese, nickel, phosphorus, silicon, and uranium.…”

“…Data locations for this tank characterization report are displayed in Table 4-1. 1975 historical sampling data (Baldwin 1996a) and have been summarized in Section 4.1. Sections 4.1.1, 4.1.2, 4.1.3, and 4.1.4 present the chemical data, the physical data, the headspace flammability results, and the HHF contamination check results, respectively.…”

“…No exothermic reactions with a change in enthalpy greater than 301.9 J/g were observed in any of the samples, as compared with the safety screening and organic complexant safety DQO decision criteria threshold of 480 Jlg, and the organic safety test plan decision threshold of 1,200 J/g. Although one of the one-sided 95 percent confidence interval on the mean upper limits was 493.4 J/g, this was attributed to variability in the data (Baldwin 1996a). All TOC results were below the decision thresholds of 30,000 pg C/g for the organic complexant safety DQO and 45,000 pg C/g for the organic safety test plan.…”
