CANDU reactors in Ontario
CANDU units at Ontario Power Generation’s Darlington and Pickering sites, as well as those at Bruce Power, were brought on line in the 1970s, 1980s and 1990s. Since then, they have continuously played an important role in providing Ontarians with a safe and reliable source of baseload electricity. Nuclear energy powers approximately half of Ontario’s home and business needs.
The CANDU 6 reactor offers a combination of proven and superior, state-of-the-art technology. It was designed specifically for electricity production, unlike other major reactor types that evolved from other uses. This focused development is one of the reasons that CANDU has such high fuel efficiency. Candu is proud of the excellent performance of its domestic and international fleet of CANDU 6 reactors.
Candu is currently marketing its Enhanced CANDU 6 reactor, a 700-MWe class heavy-water moderated and cooled reactor. It is an evolutionary design based on the successful CANDU 6 model.
In June 2013, the EC6 completed its third and final pre-licensing review by the Canadian Nuclear Safety Commission (CNSC). Read the executive summary.
Candu has also developed the Advanced CANDU Reactor® (ACR-1000®), an evolutionary, Generation III+, 1200 MWe class heavy water reactor, designed to meet industry and public expectations for safe, reliable, environmentally friendly, low-cost nuclear generation. The ACR-1000 development program has been completed to the point that the design is ready for bidding or for discussion with interested utilities.
Advanced Fuel CANDU Reactors
One of the unique features of CANDU reactor design is its ability to use alternative fuels such as recovered uranium (RU) from the reprocessing of used light water reactor fuel, low-enriched uranium (LEU) and plutonium (Pu) mixed oxide, thorium and actinides, in addition to the conventional natural uranium. Candu is currently working with China to further develop thorium as an alternative fuel source.
