A Modern Interpretation of the Barney Diagram for Aluminum Solubility in Tank Waste

Description: Experimental and modeling studies of aluminum solubility in Hanford tank waste have been developed and refined for many years in efforts to resolve new issues or develop waste treatment flowsheets. The earliest of these studies was conducted by G. Scott Barney, who performed solubility studies in highly concentrated electrolyte solutions to support evaporator campaign flowsheets in the 1970's. The 'Barney Diagram', a term still widely used at Hanford today, suggested gibbsite ({gamma}-Al(OH){su… more

The fate of organics from hot semiworks in CR vault

Description: The 244-CR vault contains four tanks: two 40,000-gallon carbon steel tanks and two 15,000-gallon stainless steel tanks. On occasion, the waste from 201-C Semiworks was routed through the tanks in 244-CR. This had the potential for mixing the organics from 201-C Semiworks and a residual heel in 244-CR which may be acidic. The purpose of this study is to determine if there is a possibility that a reactive waste could be present in 244-CR vault.

Practical Modeling of aluminum species in high-pH waste

Description: One of the main components of the nuclear waste stored at the Hanford Site is aluminum. As efforts are made to dispose of the waste, the need to predict the various phases of the aluminum becomes important for modeling of the disposal processes. Current databases of the aluminum species are not adequate as they stand. This study is not an attempt to present a rigorous discussion of aluminum chemistry, but to approach aluminum solubility as a practical application. The approach considers two dif… more

Mitigation of the most hazardous tank at the Hanford Site

Description: Various tanks at the Hanford Site have been declared to be unresolved safety problems. This means that the tank has the potential to be beyond the limits covered by the current safety documentation. Tank 241-SY-101 poses the greatest hazard. The waste stored in this tank has periodically released hydrogen gas which exceeds the lower flammable limits. A mixer pump was installed in this tank to stir the waste. Stirring the waste would allow the hydrogen to be released slowly in a controlled manne… more

Tank 101-SY Window E core sample: Interpretation of results

Description: A full depth core sample was taken for tank 241-SY-101 in December 1991 during a time period called ``Window E.`` This was the second full depth core sample from this tank during the year. The core had two major portions that are known as the convective zone and the nonconvective zone. A crust was on the top of tank but as poorly sampled. The analysis of the Window E core sample stressed segment composite chemical analysis instead of segment by segment as in Window C. Adiabatic calorimetry on s… more
