Le nucléaire au Canada

Le Canada projette un site de stockage géologique en profondeur de longue durée.
Canada’s nuclear waste to be buried in deep underground repository

May 29 2019

Canada's nuclear industry is generating enormous amounts of waste that will remain radioactive for centuries to come. As Eric Sorensen reports, plans are underway to store that used fuel in a repository deep underground, but the plan is not without controversy.

Fred Kuntz of OPG said, “The rock at 680 metres deep is impermeable. It’s dry. It’s strong. The geology at that depth below the site has been isolated from any groundwater or the lake for hundreds of millions of years.”

The deep geological repository was approved by an environmental review panel in 2015, but both the Harper and Trudeau governments have put off giving the final go ahead. It now appears to hinge on the approval by indigenous people in the region.

Projet de construction d'un SMR de 300 MWe au Canada en Ontario :
OPG applies for construction licence for Darlington SMR

02 November 2022

Ontario Power Generation (OPG) has submitted an application for a Licence to Construct a small modular reactor (SMR) at the Darlington site, where it plans to build Canada's first commercial, grid-scale SMR.

This licence is required before any nuclear construction work on the SMR at Darlington can begin. Site preparation work - which consists of non-nuclear infrastructure activities, such as clearing and grading parts of the site to build roads, utilities and support buildings, and for which the site is already licensed - began in October and is planned to continue into 2025.

The Licence to Construct application, lodged with the Canadian Nuclear Safety Commission (CNSC) on 31 October, was developed collaboratively between OPG and GE Hitachi, the designer of the BWRX-300. A number of information packages will be submitted to the CNSC in sequence, over the next six months.

According to the CNSC, a Licence to Construct requires an applicant to demonstrate that the design of the proposed facility "conforms to regulatory requirements and will provide for safe operation over the proposed plant life, and responsibility for all activities pertaining to design, procurement, manufacturing, construction and commissioning."

The regulatory review process includes opportunities for Indigenous Nations and Communities and the public to discuss the application, ask questions and raise areas of interest, OPG said, culminating in a public hearing, held by the CNSC. This is likely to take place in 2024.

The Darlington site is the only site in Canada currently licensed for a new nuclear build, with an accepted environmental assessment and site preparation licence. OPG expects to make a construction decision by the end of 2024 and has set a preliminary target date of 2028 for plant operations.

The BWRX-300 is a 300 MWe water-cooled, natural circulation SMR with passive safety systems that leverages the design and licensing basis of GEH's ESBWR boiling water reactor. It is currently undergoing a CNSC pre-licensing Vendor Design Review.

The Canada Infrastructure Bank recently committed CAD970 million (USD713 million) towards the Darlington New Nuclear Project in the bank's largest investment in clean power to date, providing financial certainty and signalling federal support for the project.

Additional SMRs in the pipeline for Darlington

07 July 2023

The Ontario government announced it is working with Ontario Power Generation (OPG) to begin planning and licensing for three additional GE Hitachi Nuclear Energy (GEH) BWRX-300 small modular reactors, for a total of four, at the Darlington plant site.

The announcement about three potential additional units builds on January's announcement about a contract to build a single BWRX-300 at OPG's Darlington site. Construction of that unit is scheduled to be completed by late 2028, with the supplying of power to the grid set to start in 2029.

Subject to Ontario Government and Canadian Nuclear Safety Commission (CNSC) regulatory approvals on construction, the additional SMRs could come online between 2034 and 2036.

This timing would allow OPG to apply learnings from the construction of the first unit to deliver cost savings on subsequent units, the government noted. Building multiple units will also allow common infrastructure such as cooling water intake, transmission connection and control room to be utilised by all four units instead of just one, reducing costs even further.

"Once deployed, these four units would produce a total 1200 megawatts of electricity, equivalent to powering 1.2 million homes, helping to meet increasing demand from electrification and fuel the province's strong economic growth," the government said.

"A fleet of SMRs at the Darlington New Nuclear Site is key to meeting growing electricity demands and net-zero goals," said OPG President and CEO Ken Hartwick. "OPG has proven its large nuclear project expertise through the on-time, on budget Darlington Refurbishment project. By taking a similar approach to building a fleet of SMRs, we will deliver cost and schedule savings, and power 1.2 million homes from this site by the mid-2030s."

"OPG and the Province of Ontario have staked a leading position in the deployment of new nuclear with a project that will offer significant energy and economic benefits to Ontario and Canada," said GEH President & CEO Jay Wileman. "As a global clean energy leader, the Province of Ontario is an ideal home for this innovative project. We look forward to working closely with the SMR project partners as we build a fleet of new reactors together and demonstrate nuclear project excellence here in Canada."

On 31 October last year, OPG submitted an application to the CNSC for a licence to construct a BWRX-300 at the Darlington site. This licence is required before any nuclear construction work on the SMR can begin. However, site preparation work is already under way at the site. OPG expects to make a construction decision by the end of 2024.

The BWRX-300 is a 300 MWe water-cooled, natural circulation SMR with passive safety systems that leverages the design and licensing basis of GEH's ESBWR boiling water reactor. The CNSC issued a positive decision in March, making the BWRX-300 the first SMR to complete such a pre-licensing Vendor Design Review in Canada.

The announcement of the additional SMRs comes days after the Ontario government announced it is starting pre-development work to build up to 4800 MWe of new nuclear capacity at Bruce Power's existing site, in what would be Canada's first large-scale nuclear build in more than 30 years.

Projet de construction de 4800 MW de centrales nucléaires en Ontario :
Ontario government announces support for nuclear expansion

06 July 2023

The province's government has announced it is starting pre-development work to build up to 4800 MWe of new nuclear capacity at Bruce Power's existing site, in what would be Canada's first large-scale nuclear build in more than 30 years.


Electricity demand in Ontario is rising for the first time since 2005, the government said. It has already implemented a plan to meet rising demand in the current decade, but Ontario's Independent Electricity System Operator (IESO) last year issued a report forecasting that the province could need to more than double its electricity generation capacity from today's 42,000 MWe to 88,000 MWe by 2050.

The IESO report recommended that Ontario begin planning, siting and environmental assessment work for long-lead assets, including nuclear power, as a "no regret" action towards meeting decarbonisation goals and increasing electricity demand driven by strong economic growth, electrification and population growth beyond 2030.

Bruce Power's eight existing Candu reactors already produce some 30% of Ontario's electricity, and the company said the site has space for "incremental infrastructure development". President and CEO Mike Rencheck said nuclear power had been the "stable backbone" of Ontario's electricity system for decades, and the long-term planning and consultation activities will determine how it can further contribute to Ontario's clean energy and economic development goals. The long-term planning and consultation activities will not impact the company's ongoing programme to secure the site's operation until 2064.

Minister of Energy Todd Smith said Ontario's "open for business approach" has led to "unprecedented" investments across the province. "With our plan already in place to meet demand this decade, we are starting the pre-development work to identify future generation options, including reliable, affordable and clean nuclear energy, that will power our province into the future," he said.

The process for approving and building new nuclear capacity could take a decade or longer, and federal approval is the first step in this process, the government said. The pre-development work will take several years to complete and will help evaluate the suitability of the site by examining the impacts of a new facility on the environment, the public and Indigenous communities, with significant public input and community consultations. It is also a prerequisite for the Canadian Nuclear Safety Commission's licensing process for a new large-scale reactor.

The Ministry of Energy said it is working with the IESO and Bruce Power on a contractual approach to address the costs associated with the pre-development work to minimise the impact on ratepayers and will also look for ways to use funds collected from the sale of clean energy credits through the Future Clean Electricity Fund to help reduce the costs for ratepayers.

Eighteen of Canada's 19 operating Candu reactors are in Ontario, where they provide around half the province's electricity. Although nuclear capacity played a key role in enabling the province to entirely phase out coal-fired electricity generation in 2014, plans for new large-scale reactors had been shelved in favour of projects by Bruce and Ontario Power Generation (OPG) to refurbish existing reactors to allow them to continue operating well beyond the middle of the century. The province is also - alongside Alberta, New Brunswick and Saskatchewan - pursuing a strategic plan to develop and deploy small modular reactors (SMRs), and OPG has begun site preparation for a grid-scale SMR at a site adjacent to its existing Darlington plant.

"Ontario's electricity system is already cleaner than California or Germany and the Bruce Power nuclear site was instrumental in helping to phase out coal and establishing Ontario's clean energy advantage," Dave Butters, president of the Association of Power Producers of Ontario, said. "Today's announcement to identify future generation options to meet rising electricity demand creates a tremendous option for the province both to meet our coming power needs, and support our transition to net-zero."

Bruce Power is located in the traditional and treaty territory of the Saugeen Ojibway Nation and the harvesting territories of the Métis Nation of Ontario and the Historic Saugeen Métis.

Remise en route du réacteur Bruce 6 aprés travaux de modernisation/extension de vie
Bruce 6 back on the grid after refurbishment

08 September 2023

The unit has been reconnected to Ontario's grid following a successful Major Component Replacement (MCR) outage that was completed ahead of schedule and on budget.

Beginning its MCR outage in January 2020, Bruce 6 is the first of six units to undergo the refurbishment process under Bruce Power's Life Extension Program, extending their operation to 2064 and beyond. According to Bruce Power, the programme is Ontario's largest clean-energy initiative and one of Canada's largest private sector infrastructure projects, funded by private-sector investors.

Bruce Power President and CEO Mike Rencheck expressed the company's pride in the people and partners, including suppliers and trades unions, who have contributed to the project. "As one of the largest nuclear operators in the world, refurbishing our units is key to providing clean, reliable energy to the people of Ontario well into the future. We have shown strong performance and we’ve committed to providing the lowest-cost nuclear energy in Ontario and to bettering our performance in each successive MCR outage," he said.

The company also thanked Ontario Power Generation (OPG) for sharing lessons learned and operating experience. OPG has completed the refurbishment of the first two of four units at its Darlington site in a ten-year programme that will enable the plant to continue operations until 2055.

Bruce 3 - which began its MCR outage earlier this year - is reaping the benefits of lessons learned in Unit 6 to achieve time and cost savings, the company said. Innovations realised in Bruce 6's refurbishment will be carried forward to improve performance and quality in subsequent MCR outages, including tooling and inspection automation and robotics, and advanced modelling and training.

Hundreds of companies, and thousands of tradespeople, are involved in each MCR. The refurbishment includes replacing and upgrading key equipment - 480 fuel channels, 960 feeders and eight team generators - in addition to thousands of other modifications and tasks, before 5,760 new fuel bundles are loaded into the reactor core.
