【 摘 要 】

In 2001, the first measurements of cesium distribution behavior in actual waste samples during the Caustic-Side Solvent Extraction (CSSX) process were reported. These measurements showed acceptable behavior across the extraction, scrubbing and stripping stages of the CSSX process. However, extraction performance was not consistent with developed thermodynamic models. Therefore, additional batch tests were performed to measure the distribution coefficients with samples from F- and H-Area high level waste Tanks.
