Reactive Transport Modeling Approach and its Initial Saltcake Dilution Chemical Modeling

Description: During waste retrieval, chemical reactions, waste property changes, and waste movements/mixing interact. Thus,to be accurate, a waste process assessment methodology must account for these physical and chemical waste characteristics and mechanisms. This study provides suggestions for column tests and simulation modeling efforts to investigate saltwell pumping of Hanford Tank S-112. In addition, GMIN chemical modeling was initiated for S-112 saltcake dilution with 50% and 100% water as the first … more

Numerical Modeling of Mixing of Chemically Reacting, Non-Newtonian Slurry for Tank Waste Retrieval

Description: In the U.S. Department of Energy (DOE) complex, 100 million gallons of radioactive and chemical wastes from plutonium production are stored in 281 underground storage tanks. Retrieval of the wastes from the tanks is the first step in its ultimate treatment and disposal. Because billions of dollars are being spent on this effort, waste retrieval demands a strong scientific basis for its successful completion. As will be discussed in Section 4.2, complex interactions among waste chemical reaction… more

Numerical Modeling of Mixing of Chemically Reacting, Non-Newtonian Slurry for Tank Waste Retrieval

Description: Many highly radioactive wastes will be retrieved by installing mixer pumps that inject high-speed jets to stir up the sludge, saltcake, and supernatant liquid in the tank, blending them into a slurry. This slurry will then be pumped out of the tank into a waste treatment facility. Our objectives are to investigate interactions-chemical reactions, waste rheology, and slurry mixing-occurring during the retrieval operation and to provide a scientific basis for the waste retrieval decision-making p… more
