Low Temperature Aluminum Dissolution (LTAD) Real Waste Testing of the November 2017 Tank 51 Slurry Sample

Speciation of Mercury in Sludge Solids: Unwashed Sludge

“…The weight percent total solids, dissolved solids (supernate basis), insoluble solids, as well as the supernate and slurry densities were reported previously on this pre-SB10 Tank 51 sample 11 and are summarized in Table 3-1 There was insufficient sample to apply Purge & Trap methods to this second tank slurry sample. Since it was not possible to measure volatile mercury species via purge and trap on the parent sample, the volatile species were measured on diluted samples of supernatant liquid as discussed in the next section.…”

Evaluation of Thermolytic Production of Hydrogen from Glycolate and Common Tank Farm Organics in Simulated Waste

“…The validation data set may be included in the linear regression to improve the quality and robustness of the Reillex HGR model. The enhanced model achieved by including the validation data set in the linear regression is given in Equation [30].…”

“…The HGR results of all Reillex testing are plotted against the enhanced Reillex model described in Equation [30] in Figure 3-37. The results plotted in Figure 3-37 show that the majority of testing with Reillex HPQ resin digestion product material are generally well-described by the model expression given in Equation [30]. All the original model generation data and the validation data sets fall within the 95% confidence limit for a single prediction.…”

“…The linearized model presented in Equation [30] is transformed for ease of implementation in Equation [31]. Given the improved fitting and robustness available with the revised model, it is recommended to use the expression given in Equation [31] to estimate the thermolytic HGR from the digestion products of Reillex HPQ and similar polyvinylpyridine-based resins in CSTF caustic waste media.…”
