OSTI ID:773111
Non-elutable ion exchange technology using crystalline silicotitanate (CST) has been studied at the Savannah River Site (SRS) for removing cesium from SRS soluble radioactive waste. The authors developed a transient model to describe the process of gas generation due to radiolysis and bubble formation in CST ion exchange (IX) columns using the Aspen Custom Modeler (ACM) software package. The model calculates gas concentrations and onset of bubble formation for large CST IX columns. The calculations include cesium loading as a function of time, gas generation as a function of cesium loading, and bubble formation as a function of gas solubility.
