A survey was made to investigate the current and future use of evaporation as a method for treating liquid radioactive streams at light-water-cooled nuclear reactor (LWR) power plants. Pertinent data were obtained by contacting utility companies, nuclear-steam-supply system vendors, and architect-engineers, as well as evaporator manufacturers and vendors. Principal interest was placed upon obtaining operating data on the performance of evaporators used at LWR plants to treat radioactive liquid streams containing primarily (a) several tens to several thousand ppm of boron (pH of ~4 to 10), (b) several tens to ten thousand ppm of boron plus several hundred to ten thousand ppm of sodium and ammonium sulfates (pH of ~3 to 11), and (c) up to several ten thousand ppm of sodium sulfate (pH of ~6 to 9).
