Analysis of organic carbon and moisture in Hanford single-shell tank waste

“…Notice that the log transformed data appears normally distributed. This transformation is reported in detail in Toth et al (1994). Also, similar observations have been made for the data within any particular phase.…”

“…The information provided in this report is a continuation of the initial Pacific Northwest Laboratory study (PNL)'") completed in April 1994 (Toth et al 1994) that estimated TOC based on available tank characterization datasets. This initial study used historical TOC laboratory data from WHC characterization datasets.…”

“…The first step in conducting this study was to thoroughly review the earlier investigation "Organic Carbon in Hanford Single-Shell Tank Waste" (Toth et al 1994). Those results were reexamined in this study to reflect new laboratory data.…”

“…The TOC and moisture measurement data were the primary source for estimating the contents of the tank. The TOC values previously reported in Toth et al (1994) formed the framework for the dataset presented here. All data are reported as wet basis TOC.…”

Safety evaluation of interim stabilization of non-stabilized single-shell watch list tanks

“…If no current waste List Tank to be interim stabilized would need to be determined prior to pumping to assess if the TOC (dry basis) is 5 3.0 wt.%. sample analysis was available to make this determination, (Toth et al 1994) which is based upon a review of laboratory analytical data performed by Pacific Northwest Laboratory (PNL), could be used.…”
