Data Observations on Double Shell Tank (DST) Flammable Gas Watch List Tank Behavior

“…This effect is generally consistent with the behavior observed in simulant studies by Barefield et al (1996), Camaioni et al (1995Camaioni et al ( , 1996, and Meisel et al (1993). It has also been mentioned as an explanation for higher hydrogen concentrations in the floating crust layer whose surface is exposed to the air in the tank headspace [RGS measurements reported by Mahoney et al (1999) showed 32 to 40% hydrogen in the SY-101 crust layer].…”

“…It may be possible to indirectly prove that waste solids do contain energetic species by comparing the amount of degradation of CA compared to the increase in oxalic acid. Citric acid appears to be less reactive than either HEDTA and EDTA; these results have been confirmed by Camaioni et al (1996) and by analyzing the heated SY-103 samples (Bryan et a]. 1996).…”

The Chemistry of Flammable Gas Generation

“…For clarity, the important byproducts of the reactions, oxalate, formate, and carbonate ion, are shown only in the final reaction in the figure. The products designated in bold face have been detected in tank waste or in simulants by several investigators (Campbell et al 1994Ashby et al 1994;Barefield et al 1995Barefield et al , 1996Camaioni et al 1996aCamaioni et al , 1996bCamaioni et al , 1997Camaioni et al , 1998Evans et al 1999). …”
