【 摘 要 】

The proposed use of crystalline silicotitanate (CST) for removal of radiocesium from Savannah River high level waste has received significant research over the past few years. Engineering evaluations of the proposed flow sheet identified several risks. These risks include chemical and thermal stability of the resin, gas generation in the large ion exchange columns, and size reduction and sampling issues for interfacing with the Defense Waste Processing Facility. Research into these potential risks provided information that mitigates or eliminates these risks.
