The Hanford Tank Waste Treatment and Immobilization Plant (WPT) project is completing solubility models for nitrate salts to evaluate control of the Cesium Nitric Acid Recovery Process (CNP) in order to avoid precipitation of solids in the evaporator concentrate. In order to do this, bench scale tests to determine salt solubility in nitric acid solutions at expected feed and final evaporated concentrations will be done. This work will provide the necessary data to verify predicted salt solubilities and basic physical / thermodynamic data for the modeling of the evaporator system.
