Decontamination support for Ontario hydro operation and maintenance
The decontamination of various systems and equipment has been a key element in the operation and maintenance programs of Ontario Hydro CANDU reactors. Currently, 16 reactors are in service and 4 under construction. Decontamination is used both to control external radiation fields as well as to minimize loose contamination. Additional benefits invariably accrue, such as a reduced number of maintenance workers required, increased productivity, and increased morale. A central technical service organization was established to provide decontamination recommendations, expertise, and equipment to our station. To provide an all-around service, a variety of decontamination techniques have been developed. The success of the program is best demonstrated by discussion of two examples: primary heat transport system decontamination using the CANDECON process and steam generator channel head decontamination using high-pressure water jetting.
