Work kicks off on Darlington Unit 1 refurbishment
Work on the third of four nuclear reactors at the Darlington Nuclear Generating Station has officially begun.
Ontario Power Generation (OPG) announced the start of refurbishment work at the Darlington station’s Unit 1 on February 15.
The beginning of work at the reactor means that OPG has passed the mid-point in its 10-year, $12.8-billion project to extend the life of the Darlington station. The refurbishments will enable the station to produce energy for at least another 30 years. Work on the project kicked off in October 2016.
“Refurbishing Darlington Nuclear Generating Station is key to OPG’s Climate Change Plan,” said OPG President and CEO Ken Hartwick. “This workhorse generates over 20 percent of Ontario’s electricity without greenhouse gas or carbon emissions each year. Thanks to this mid-life overhaul, Darlington will continue to cleanly power Ontario’s homes, hospitals and businesses for decades to come.”
The first refurbishment unit, Unit 2, was returned to service in June 2020. After a brief delay related to the COVID-19 pandemic, work on Unit 3 began in September 2020. Now, with Unit 3 in the midst of reassembly, refurbishment of Unit 1 begins. For the first time on the project, two units are being refurbished at once.
Work on Unit 4, the final unit to be refurbished, is scheduled to begin in the third quarter of 2023.
The overall project remains on track for completion by the end of 2026.
“The refurbishment team’s successful track record on Units 2 and 3, combined with detailed planning for Unit 1, position us well for continued success,” said Subo Sinnathamby, OPG Senior Vice President, Nuclear Refurbishment. “Continuous learning and working as a team with our vendor partners and Bruce Power have been key to our success to date. We continue to apply innovations and lessons learned to ensure even better performance as we move forward through this project.”
According to a report by the Conference Board of Canada, the Darlington refurbishment project and the subsequent 30 additional years of station operation are expected to generate a total of $89.9 billion in economic benefits for Ontario, create 14,200 jobs per year, and boost personal income by an average of $1.6 billion on an annual basis.
With 96 percent of project costs spent in the province and a heavy reliance on Ontario-based contractors, for every $1 spent on the project, Ontario’s GDP will increase by an average of $1.40.
Continued operation of the Darlington station is also key to helping Ontario meet its climate change goals. An independent report prepared by Intrinsik Environmental Sciences noted that the continued operation of Darlington Nuclear to 2055 will take the equivalent of two million cars off Ontario’s roads per year by avoiding significant greenhouse gas emissions.
In December, OPG announced it will work with GE Hitachi Nuclear Energy to deploy a Small Modular Reactor at the Darlington new nuclear site, the only site in Canada currently licensed for a new nuclear build.
