A Radioactive Liquid Waste Concentration facility utilizing wiped-film evaporation and mixed-bed ion exchange treatment has been constructed and evaluated. Low-level wastes to be treated include reactor primary coolant water, liquid decontamination waste generated at reactor sites, and decontamination, laboratory, and laundry waste generated by research laboratories utilizing radioactive isotopes. Some data are reported for processing of alkaline permanganate, hydrazine versenate, ammonium citrate, and potassium tetraborate tetrahydrate solutions. The evaporator operated trouble free and antifoam agents were not required since foaming was not a problem. Operating experience and a cost evaluation are included. (Author).
