Ontario’s bold nuclear expansion: BWXT secures contracts for Pickering and Darlington projects

Ontario’s nuclear energy strategy has reached a significant milestone with BWX Technologies, Inc. (BWXT) securing contracts exceeding C$1 billion for two transformative projects. These initiatives focus on extending the life of the Pickering Nuclear Generating Station and deploying Canada’s first small modular reactor (SMR) at the Darlington New Nuclear Project.

BWXT, known for its advanced nuclear manufacturing capabilities, will play a key role in these projects, which aim to address Ontario’s increasing electricity demand while reducing carbon emissions. The contracts are expected to bolster local economies, create thousands of high-paying jobs, and reinforce Canada’s position as a global leader in clean nuclear energy.

What Is the Pickering Life Extension Program and Why Is It Crucial?

The Pickering Nuclear Generating Station, located 45 kilometres east of Toronto, has been a cornerstone of Ontario’s energy grid for over five decades. Under the Pickering life extension program, BWXT will manufacture 48 steam generators at its Cambridge facility. These components will enable four CANDU reactors in the station’s “B” fleet to continue operating until the mid-2060s.

This project will help Ontario meet its projected 75% increase in electricity demand by 2050, driven by population growth and industrial expansion. Pickering currently accounts for 10% of Ontario’s electricity supply, making its continued operation vital for maintaining reliable baseload power.

The initiative is expected to create more than 250 highly skilled trades jobs, including welders, fitters, and machinists. Additionally, it will secure over 4,500 jobs across Ontario’s nuclear sector, reinforcing the province’s position as a hub for nuclear innovation.

Nicolle Butcher, President and CEO of Ontario Power Generation (OPG), emphasized the importance of collaboration:

“Refurbishing existing assets like Pickering and deploying new technologies at Darlington allows us to meet growing energy demands while maintaining our commitment to clean, affordable electricity for Ontarians.”

How Does the Darlington SMR Project Lead Canada’s Nuclear Advancements?

BWXT’s second major contract involves manufacturing the reactor pressure vessel (RPV) for the GE Hitachi BWRX-300 SMR, which is set to be Canada’s first grid-connected SMR. This 300-MWe water-cooled reactor employs passive safety systems and is designed to offer high efficiency while reducing construction and operational costs.

The Darlington New Nuclear Project is on track to make history as the first SMR deployment among G7 nations, cementing Canada’s leadership in next-generation nuclear technology. Stephen Lecce, Ontario’s Minister of Energy and Electrification, highlighted the SMR’s potential:

“Ontario’s highly skilled workers and strong nuclear supply chain are making it possible to deploy innovative technologies like the BWRX-300, ensuring a reliable and clean energy future.”

As the largest manufacturer of nuclear components in North America, BWXT’s Cambridge facility is undergoing an C$80 million expansion to meet growing demand. This investment reflects the rising importance of nuclear energy in global clean energy strategies.

Why Is CANDU Technology Vital for Ontario’s Energy Security?

CANDU reactor technology, developed in Canada, is a key pillar of Ontario’s energy strategy. Unlike traditional reactors, CANDU units use natural uranium fuel and can be refueled without shutting down, ensuring high efficiency and minimal operational disruptions.

Beyond power generation, CANDU reactors support critical global health initiatives by producing Cobalt-60, a medical isotope used in cancer treatments. The Pickering station alone accounts for 20% of the global supply of this essential resource, making it indispensable to the healthcare industry.

Joe St. Julian, President of Nuclear at AtkinsRéalis, underscored the value of CANDU technology:

“It’s a source of national pride and a cornerstone of Canada’s energy security. Projects like Pickering ensure clean, reliable energy while supporting thousands of jobs across Ontario.”

What Are the Economic and Environmental Impacts of These Projects?

The Pickering life extension and Darlington SMR projects bring substantial economic and environmental benefits. The refurbishment of Pickering will help maintain Ontario’s status as a leader in low-carbon energy. By avoiding the equivalent of emissions from over 600,000 gas-powered cars annually, the station contributes significantly to Canada’s climate goals.

The projects also represent a major economic stimulus, creating jobs in engineering, manufacturing, and skilled trades while supporting local businesses. For example, the Pickering initiative will inject billions into Ontario’s economy over the next decade, further solidifying the province’s nuclear supply chain.

How Does Ontario’s Nuclear Strategy Shape Its Energy Future?

Ontario’s broader nuclear strategy includes refurbishing 19 CANDU reactors, constructing four SMRs at Darlington, and exploring new nuclear sites in southern Ontario. Together, these efforts aim to provide a stable, weather-independent energy source as the province transitions away from fossil fuels.

In October 2024, the Canadian government approved the extension of Pickering’s operations until 2026, underscoring the station’s critical role in meeting Ontario’s energy needs. As one of the world’s largest nuclear plants, Pickering currently generates 11% of the province’s electricity, powering approximately 1.5 million homes annually.

A Blueprint for Clean Energy Growth

Ontario’s investments in the Pickering life extension and Darlington SMR projects demonstrate its commitment to clean, reliable, and affordable energy. By leveraging innovations like CANDU technology and collaborating with industry leaders such as BWXT, AtkinsRéalis, and Aecon, the province is setting a global standard for sustainable energy development.

As the world seeks to address rising energy demands and climate change, Ontario’s nuclear strategy offers a roadmap for balancing economic growth with environmental stewardship.
