Use of Modeling for the Prevention of Solids Formation During Canyon Processing of Legacy Nuclear Materials

Description

This report describes the effort to develop a predictive model of the stability of aqueous solutions of nuclear materials will enable the avoidance of concentrations that may cause salts to precipitate. Therefore, for the processing of off-normal material, the risk of producing unwanted solids that require processing to stop will be reduced. Processing delays result in higher operating costs. In addition, the improved model may reduce the work scope for future flowsheet development by identifying the concentration of dissolver solutions that avoid the precipitation of salts. As an initial impact, the improved INEEL model should reduce costs for the processing ... continued below

Description

This report describes the effort to develop a predictive model of the stability of aqueous solutions of nuclear materials will enable the avoidance of concentrations that may cause salts to precipitate. Therefore, for the processing of off-normal material, the risk of producing unwanted solids that require processing to stop will be reduced. Processing delays result in higher operating costs. In addition, the improved model may reduce the work scope for future flowsheet development by identifying the concentration of dissolver solutions that avoid the precipitation of salts. As an initial impact, the improved INEEL model should reduce costs for the processing of difficult-to-dissolve residues from the Rocky Flats Environmental Technology Site by shortening the time it takes to determine dissolving solutions. As a long-term impact, this model should improve schedules to dissolve other off-normal nuclear materials and process aqueous solutions that are stored throughout the DOE complex.
