As North America transitions towards a low-carbon future, nuclear power is becoming a critical part of the energy strategy. With rising energy demand and aggressive decarbonization goals, nuclear energy presents a scalable, reliable, and carbon-free solution. Recent investments are growing in both traditional reactors and cutting-edge nuclear technologies like Small Modular Reactors (SMRs). North American governments and private companies are committing billions to bolster nuclear infrastructure as a key component of the continent's clean energy landscape.
The Case for Nuclear: Why It’s Critical for North America’s Energy Future
Nuclear power has a significant role in providing baseload energy—the constant, reliable power needed to meet around-the-clock demand. Unlike renewables such as wind and solar, which depend on weather conditions, nuclear provides uninterrupted electricity generation. In North America, nuclear power currently generates 18.2% of the United States' electricity and 15% of Canada’s, according to the U.S. Energy Information Administration (EIA) and Natural Resources Canada.
As both nations aim to reach net-zero emissions by 2050, nuclear power is recognized as an essential part of achieving those goals. According to a 2023 McKinsey report, nuclear energy capacity would need to expand by 60-100% in North America by 2050 to meet decarbonization targets, replacing coal and natural gas while complementing renewables.
Key Investments in Nuclear Power
1. Small Modular Reactors (SMRs): The Future of Flexible Nuclear Power
The potential for Small Modular Reactors (SMRs) is driving the bulk of new nuclear investments in North America. These reactors are smaller, scalable, and faster to deploy than traditional nuclear plants, making them ideal for various applications from powering remote communities to supplementing industrial power needs.
Canada’s $1.6 Billion SMR Push: Canada has committed $1.6 billion to SMR development, with Ontario Power Generation (OPG) leading the charge. The first commercial SMR at the Darlington Nuclear Site is set to be operational by the late 2020s, and Canada is collaborating with U.S. partners to advance SMR technology across North America. Natural Resources Canada estimates SMRs could contribute 5,000 MW of new capacity by 2040.
NuScale’s $6 Billion SMR Project in the U.S: In the U.S., NuScale Power is leading the SMR race, with its modular reactor design receiving approval from the U.S. Nuclear Regulatory Commission (NRC). NuScale plans to build its first SMR plant in Idaho by 2029, with a total cost of $6 billion. The plant will deliver 462 megawatts (MW) of carbon-free power, potentially expanding to other regions as demand increases.
2. Advanced Reactor Technologies: The Next-Gen Nuclear Revolution
Beyond SMRs, North America is also investing heavily in advanced reactor technologies, which promise greater efficiency, safety, and the ability to use alternative fuels.
TerraPower’s $4 Billion Natrium Reactor: Backed by Bill Gates, TerraPower is developing its Natrium Reactor, a sodium-cooled fast reactor that promises enhanced safety and flexibility. The company received $2 billion in funding from the U.S. Department of Energy (DOE) to build a demonstration plant in Wyoming by 2028. The total project cost is estimated at $4 billion, with additional private investments expected to follow.
Molten Salt Reactors in Canada: In Canada, companies like Terrestrial Energy are working on molten salt reactors, which offer increased fuel efficiency and produce less waste. Terrestrial Energy is receiving government support, including part of Canada’s $120 million investment into next-gen nuclear technologies. The company aims to have a commercial molten salt reactor operational by 2035.
While new technologies are crucial, maintaining and extending the life of existing nuclear reactors is equally important. Many plants in North America are undergoing multi-billion-dollar refurbishment projects to extend their operational lifespans by decades.
Bruce Power’s $13 Billion Life Extension: Ontario’s Bruce Nuclear Generating Station, one of the largest nuclear plants in the world, is undergoing a $13 billion life extension project. This program, running until 2033, will allow Bruce Power to continue producing 6,200 MW of clean energy until 2064, providing about 30% of Ontario’s electricity.
Vogtle Nuclear Plant Expansion ($34 Billion): In the U.S., the Vogtle nuclear plant in Georgia is in the process of bringing two new reactors online. Once complete in 2024 and 2025, the expansion will have cost $34 billion, making it the first new nuclear construction in the U.S. in over 30 years. The two new reactors will add 2,200 MW of clean energy to the grid.
Financial Metrics: Nuclear Investments in Perspective
In the U.S., government support for nuclear power is substantial. The Inflation Reduction Act (IRA) passed in 2022 allocates $30 billion in tax credits, grants, and subsidies for clean energy projects, with a significant portion directed toward nuclear development.
Canada’s Strategic Innovation Fund and the Net-Zero Accelerator Initiative are providing billions in funding to support nuclear energy, including a $1 billion fund for SMR projects by 2030. Moreover, Canada’s investments in its national nuclear program could unlock $15 billion in economic activity by 2050, according to the Canadian Nuclear Association.
Metrics on Energy Demand and Carbon Reduction
As North America moves toward carbon neutrality, nuclear power will play a key role in displacing fossil fuel generation. According to the International Energy Agency (IEA), nuclear power could avoid up to 6 billion metric tons of CO2 emissions** by 2050 globally, with North America accounting for nearly 20% of that reduction.
For example, extending the life of the Bruce Nuclear Plant alone will avoid 500 million tons of CO2 over its lifetime, equivalent to taking **3 million cars off the road each year. Similarly, the Vogtle reactors will supply enough energy to avoid 10 million tons of CO2 annually, contributing significantly to U.S. climate goals.
Challenges Facing Nuclear Power
While nuclear power is an attractive clean energy solution, there are challenges to scaling these investments.
1. High Upfront Costs: While nuclear power provides long-term, low-cost energy, the initial capital costs are steep. A large reactor can cost upwards of $10 billion, and SMRs, while cheaper, still require significant investment for initial deployment.
2. Public Perception: Despite its low carbon footprint, nuclear energy faces skepticism, especially after high-profile accidents like Chernobyl and Fukushima. The industry will need to focus on public engagement and education to overcome safety concerns and promote its role in a clean energy future.
3. Waste Management: The disposal of nuclear waste remains a critical issue. Though advances in reactor technology aim to minimize waste, finding long-term solutions for storage, such as deep geological repositories, is still a challenge that must be addressed.
The Road Ahead: Scaling Nuclear for a Clean Energy Future
Nuclear power is no longer just a relic of the past but a key pillar in North America's future energy landscape. With billions in investments flowing into SMRs, advanced reactors, and plant refurbishments, the nuclear industry is poised to grow significantly. According to Bloomberg NEF, nuclear power investments in North America could exceed $120 billion by 2050, contributing up to 25% of total electricity generation.
As governments and industries align on the need for sustainable energy, nuclear power is proving to be a reliable, scalable solution. With continued investment, innovation, and public support, nuclear energy could help North America achieve its net-zero targets, ensuring a stable and clean energy future for decades to come.
