Ontario Hydro has 5500 MW of nuclear generating capacity presently about 1/5 of total capacity and this proportion is expected to increase markedly over the next decade. The units are all CANDU pressurized heavy water reactors. The largest station, Bruce NGS, has 4 units with a total capacity of 3200 MW. Each Bruce unit has vertical inverted U-tube Inconel 600 steam generators with triple foil broached carbon steel tube support plates. The proposed Darlington NGS will have 3600 MW capacity with similar steam generators to the Bruce station but tubed with Sanicro 30 alloy. Both these stations are on fresh water sites; typical Lake Huron water analyses (Bruce NGS) and Lake Ontario water analyses (Darlington NGS) are shown in Table 1.
