The Salt Disposition Systems Engineering Team selected three cesium removal technologies for further development to replace the In Tank Precipitation (ITP) process: small tank tetraphenyl-borate (TPB) precipitation, crystalline silicotitanate (CST) ion exchange, and caustic solvent extraction. As a pretreatment step for the CST and solvent extraction flowsheets, the incoming salt solution that contains entrained sludge is contacted with monosodium titanate (MST) to adsorb strontium and plutonium. The resulting slurry is filtered to remove the sludge and MST. The filtrate is either contacted with CST in an ion exchange column or processed through a solvent extraction system to remove cesium.This report describes the evaluation of alternate solid -liquid separation technologies. The other tasks will be described in separate reports.
