Supernatant treatment technology development: Report for the second quarter FY 1994
- and others
This report describes the experimental work conducted at the Pacific Northwest Laboratory during the Second Quarter FY 1994 under the Supernatant Treatment Technology Development Task of the Tank Waste Remediation System (TWRS) Pretreatment Technology Development Project. The project goal is to remove enough cesium-137 from the tank waste so that the resulting low-level waste form will meet Nuclear Regulatory Commission requirements. Experiments were performed in the areas of batch equilibrium studies of ion exchangers, ion exchanger loading, ion exchanger elution, and radiation and chemical stability of selected ion exchangers. Column loading experiment results showed that cesium removal efficiency was lower than predicted. Elution experiments showed that BSC-210 material for cesium removal was superior to another material tested. Radiation and chemical stability studies were continued on Resorcinol-Formaldehyde resins. 10 refs., 11 figs., 3 tabs.
