The Bruce Heavy Water Plant is operated by Ontario Hydro at the Bruce Nuclear Power Development at Douglas Point, Ontario. The plant uses as its principal working fluids, hydrogen sulfide and water. These are corrosive to carbon steel but may, under favourable conditions, rapidly form an adherent passivating iron sulfide film. Piping so passivated is called “conditioned”. New units have been added at Bruce and these have been preconditioned by circulating hydrogen sulfide and water under controlled conditions as part of the commissioning program.
