This report presents a pilot fractional distillation plant designed for decontaminating the residual solvents produced by the Centre's Waste Processing Station. These contaminated solvents come from the decontamination of a screw extrusion apparatus with perchlorethylene; this equipment is used for coating the radioactive sludges with bitumen. The pilot plant operates discontinuously and is used to decontaminate the perchlorethylene, to separate the perchlorethylene from the water, and to process the distillation residue.

The electrically heated boiler is fitted with a removable base in the form of a disposable container. The installations decontamination factor is 3. The decontamination factor for the installation is better at atmospheric pressure than in a vacuum. Decontamination par distillation fractionnee d'un melange radioactif constitue par du perchlorethylene, du bitume et des boues de coprecipitation chimique.
