Decontamination Experience in Ontario Hydro

This paper describes the decontamination of a Bruce Nuclear Generating Station heat exchanger. The heat exchanger, tubed with Incoloy-800 was contaminated with both neutron activated corrosion products and fission products. Sequential decontaminations using the CANDECON process, followed by alkaline permanganate (AP) and Decon-Turco 4521A, were used. Decontamination factors of between 8 to 12 and 10 to 50 were achieved on the tube bundle and tubesheet, respectively. The cost effectiveness of these and their effects on system materials will be discussed.
