Further Info] The Darlington Nuclear Generating Station (DNGS) is a 3524 MW(net), 4-unit CANDU station on the shore of Lake Ontario about 70 km east of Toronto, Ontario. Darlington is Ontario Power Generation’s (OPG’s) newest and largest nuclear station, providing about 20% of Ontario’s electricity supply (the equivalent of about 2 million homes), or about CDN$1 billion per year worth of electricity at an arbitrary market price of $0.04/kWh. Darlington was designed and built by Ontario Power Generation (then Ontario Hydro), and brought into service between 1990 and 1993 at a final cost of CDN$14.5 billion (1993 dollars). This represents almost twice the estimated final cost (capital + construction) of CDN$7.4 billion (1993 dollars) projected at the time that construction started in 1981 [1]. About 70% of this c
