Gas generation from Tank 241-SY-103 waste

“…The organic components of the convective layer will be analyzed under the Actual Waste Organic Analysis task according to procedures outlined in Campbell et al 1994. The organic analysis is still under way; these data will be reported in a subsequent report that will also include the gamma enhanced gas generation data.…”

The Chemistry of Flammable Gas Generation

“…Early work (Delegard 1980(Delegard , 1987 implied that new organic compounds derived from the original organic substances were being formed and were accumulating in the waste tanks. This suggestion was confirmed by subsequent work that demonstrated the presence of new substances such as iminodiacetate ion (IDA) -NH(CH2COY)z -and oxidized compounds such as formate ion, neither of which had been employed in waste processing operations (Campbell et al 1994). These results strongly suggested that the organic constituents were being oxidized under the influence of the radiation field.…”

“…The organic compounds in the wastes have been identified by gas and liquid chromatography, mass spectrometry, and other advanced analytical methods (Campbell et al 1994Pool and Bean 1994;Wahl et al 1995). The concentrations of the original complexants and their principal oxidation products have been determined in the laboratories at the Hanford Site and the Pacific Northwest National Laboratory for samples from more than 20 single-shell and double-shell tanks (Campbell et al 1994Pool and Bean 1994;Wahl et al 1995).…”

“…The concentrations of the original complexants and their principal oxidation products have been determined in the laboratories at the Hanford Site and the Pacific Northwest National Laboratory for samples from more than 20 single-shell and double-shell tanks (Campbell et al 1994Pool and Bean 1994;Wahl et al 1995). The results compiled by Meacham and Camaioni et al (Meacham et al 1998;Camaioni et al 1998) for single-shell tanks are summarized in Table 2-3.…”

“…The relative standard deviations for the TOC and oxalate analyses provided in the characterization reports were used to estimate the standard deviation in the percentage of organic carbon in oxalate. For tanks 241-SY-101 and 241-SY-103, the best basis inventory for TOC was adopted, but the oxalate ion inventory was assessed from the oxalate ion analysis provided by speciation reports (Campbell et al 1994, 1995~1, 1995b.…”
