Canada’s Independent Electricity System Operator has confirmed that the 6550 MW Bruce Power nuclear plant has met the terms and conditions of the company’s Basis of Estimate to proceed with the unit’s Major Component Replacement Project, scheduled to begin in 2026.
The eight pressurised heavy-water Candu reactor units at the Bruce site in Ontario (Bruce A, units 1-4, and Bruce B, units 4-8) began commercial operation between 1977 and 1987. Bruce Power’s CAD 13 billion ($10bn) Life Extension Programme and MCR Projects are aimed at extending the operational life of each reactor by 30-35 years.
The progamme began in 2016. MCR, which began with unit 6 and also includes units 3-8, will extend the life of the site until 2064. Units 1&2 have already been refurbished and were returned to service in 2012.
Work began on unit 3 in March 2023. Unit 6 was taken offline for the refurbishment in January 2020 and was returned to service in 2023.
“Our government is squarely focused on delivering affordable power while building, buying, and securing more energy that is built by and for Canadians,” said Stephen Lecce, minister of Energy & Mines. “I am proud that well over 90% of all materials purchased are stamped with ‘Made in Canada,’ creating over 20 000 jobs for Ontario’s skilled workforce.”
IESO CEO & president Lesley Gallinger noted: “With demand for electricity forecast to rise over the next 25 years, ongoing refurbishments of Bruce Power’s nuclear units … supports the long-term reliability, affordability and sustainability of Ontario’s electricity system. and contributes significantly to the economic and social well-being of communities across the province.”
