Precipitation and ion-exchange methods are being developed to decontaminate Oak Ridge National Laboratory process wastewaters containing small amounts of {sup 90}Sr and {sup 137}Cs while minimizing waste generation. Many potential processes have been examined in laboratory-scale screening tests. Based on these data, five process flowsheets were developed and are being evaluated under pilot- and full-scale operating conditions. Improvements in the existing treatment system based on this study have resulted in a 66 vol % reduction in waste generation. 19 refs., 26 figs., 45 tabs.
