Hydraulic Performance and Gas Behavior of a Tall Crystalline Silicotitanate Ion-Exchange Column
- ORNL
Crystalline silicotitanate (CST) sorbent is one of several technologies being evaluated by the Savannah River Site (SRS) for removing cesium from high-level tank-waste supernatant. As currently envisioned, three large 5-ft-diam, 20-ft-high ion-exchange columns will be operated in series at a superficial velocity of 4.1 cm/min. The CST will be subjected to a high radiation field from the sorbed cesium. The tests described in this work were conducted to evaluate column hydraulics, to identify changes in the CST particles during operation, to explore how radiolytic gases generated during operation behave, and to demonstrate sluicing of CST into and out of columns.
