Ontario Power Generation (OPG) said June 28 that it has received detailed construction plans, schedules and cost estimates for two potential nuclear reactors at the Darlington site.
The submissions, by Westinghouse Electric Canada and SNC-Lavalin Nuclear/Candu Energy, were commissioned last year and will help inform the government’s decision on whether to move forward with new nuclear at Darlington.
The two reactor designs that were studied were:
- The Enhanced Candu 6 reactor designed by Candu Energy, a unit of SNC-Lavalin;
- The AP 1000 reactor designed by Westinghouse.
The completed submissions will be analyzed by a team from OPG and the ministries of Energy, Finance, and Infrastructure Ontario. This review process will take a number of months to complete, OPG pointed out.
In May 2012, the federal government approved the Darlington New Nuclear Project Environmental Assessment. It concluded the project will not result in any significant adverse environmental effects, as long as there is mitigation. The Canadian Nuclear Safety Commission has also granted a site preparation license, but no work has been done at the site to this point.
All decisions on whether to move forward with the two potential nuclear reactors will be made by the government of Ontario, OPG said.
The existing Darlington Nuclear Generating Station is OPG’s newest CANDU (CANadian Deuterium Uranium) nuclear station. It is a four-unit facility with a total output of 3,512 MW and is located 70 kilometers east of Toronto.
The Darlington addition project involves the possible construction and operation of up to four nuclear reactors and up to 4,800 MW of electrical capacity and associated facilities. The early need would be for only 2,000 MW of the total new capacity.
