“…These additional-water cases also indicate that there.are no adverse effects for waste retrieval operation as well. Although the current TEM also identified Al2S4010 as one of the solids present in the sludge, several measurements of a Si amount in the sludge indicate that the sludge has much smaller amount of Si than the amount of AI (DiCenso et al 1995). Thus, a majority of Al is not expected to form a solid with Si.…”

“…The most recent Tank Characterization Report by DiCenso et al (1995) reported the distribution of particle sizes for a sample of Tank SY-102. It is clear that the particle size distributions presented in the current report are significantly smaller and more broad-band than the results in DiCenso.…”

“…This Phase I conclusion was based on simplified assumptions and conditions, e.g., tank wastes are fully mixed; data in the Tank 241-SY-102 characterization report (DiCenso et al 1995) are accurate; and formulas for fluid and slurry rheology are applicable. Most of the uncertainties on the preliminary assessment was related to data of waste characteristics and the assumption of the-tank being fully mixed.…”

Executive SummaryWastes stored in Hanford Tank 241-SY-10 are planned to be retrieved from the tank and transferred to 200 East Area through the new pipeline Replacement Cross Site Transfer System (RCSTS). This report describes results of the second phase (the detailed assessment) of a the SY-102 waste retrieval study, which is a part of the efforts to establish a technical basis for mobilization of the slurry, waste retrieval, and slurry transport. This second-phase study was performed to close uncertainty issues on Tank SY-102 waste retrieval identified under the previous preliminary assessment (Onishi and Hudson 1996). The uncertainties on the preliminary assessment were primariiy related to lack of data on waste characteristics and the assumption of the tank being fully mixed. To resolve these issues, this Phase 11 study 1) identified solid phases of the SY-102 waste by using transmission electron microscopy (TEMJ, 2) conducted laboratory experiments to measure rheology, zeta potential to evaluate solid agglomeration, and sedimentation, 3) measured particle size distributions of the wastes, and 4) simulated time-varying, three-dimensional, tank pump jet mixing.The Phase 11 study results confirms the validity of the assumptions and parameter selections used in the preliminary assessment (Onishi and Hudson 1996) and supports its conclusion that the SY-102 waste m i h g and heating do not adversely impact the waste retrieval operation. . Specific conclusions of this study are briefly summarized below.The Transmission Electron Microscopy results show that the morphology of the agglomerates is dominated by large size (2-5 pm x 10-30 pm) NaOH rods s~o u n d e d by finer primary particles of various materials. A large population of amorphous silica and iron hydroxide primary particles in the nanometer size range was' observed. Also, needle-like FeO(0H) agglomerates and sharp-edged plate-like y-A1203 particles were found. Irregt&x U-containing agglomerates and rectangular MCrcontaining particles were also present. The major 'crystalline phases observed include: micrometersized y-Al2O3, needle-like FeO(0H) and Al2Si4010. The minor crystalline phases observed were rodlike particles of hydroxylapatite, Cas(PO)3(OH) and single crystalline gibbsite, Al(OH)3. t rod-like particles of hydroxylapatite, Ca5(PO)3(OH) and single crystalline gibbsite, Al(Orn.3. The preliminary assessment study (Onishi and Hudson 1996) assumed the all Al solids to be gibbsite for the chemical reaction modeling. The current TEM identified Al solids to be y-Al2O3, Al$34010, and gibbsite.Gibbsite and y-A1203 are chemically similar. Moreover, existence of y-Al2O3 would slightly increase the amount of water in the solution, as compared with gibbsite. Moreover, since the sludge has a much smaller amount of Si than the amount of Al, the majority of Al is not expected to form a solid with Si. Thus, the prelimina...
