SOLIDIFICATION OF RADIOACTIVE LIQUID WASTE BY POT CALCINATION

Technical Report ·
OSTI ID:4064226
The pot calcination process for conventing high-activity waste to solids for permanent disposal consists of evaporation to dryness and calcination at 900 deg C in a portable stainless-steel pot, which can be used as the final storage container. Off-gases are processed by condensation, absorption and fractionation. Calcination rates corresponding to 20 liters of concentrated waste per hour were demonstrated in 6- and 8-in.-diameter by 84-in.-high stainless-steel pots with a total noncondensable off-gas production of less than 200 liters/hr. The process is simple and versatile enough to handle the variety of wastes produced by a multipurpose power-reactor fuel-processing plant. (auth)
