The AI Boom Just Revived an Industry Thought Dead

The world’s return to nuclear power is not a fad but the product of converging pressures—AI-driven electricity demand, war and geopolitical risk, and the physics of climate mitigation—yet this “third wave” of nuclear promotion will only matter if countries such as Canada can turn ambitious reactor plans into real steel, fuel, and safely managed waste.

Key Points

Canada’s plan for up to ten new reactors and first-of-a-kind SMR deployment positions it as a North American anchor of nuclear fuel and baseload supply.
AI and data center growth, climate targets, and war-driven energy insecurity are jointly reviving interest in nuclear, but global deployment still lags political rhetoric.
Cost, construction timelines, and the unresolved waste problem remain the core constraints; waste and weapons linkages are the most potent sources of public opposition.
Whether this nuclear “renaissance” sticks will depend less on technology and more on financing, regulation, and credible answers to proliferation and waste risks.

Canada’s Nuclear Bet: Reactors, Uranium, and Workforce

Canada’s current strategy represents one of the most aggressive nuclear expansion plans in the Western world. The federal Nuclear Energy Strategy lays out a pathway for up to ten new large-scale reactors, with two units targeted by 2035 and five more by 2040, alongside further opportunities identified thereafter.^[6] This is not an offhand political promise; it is an official planning document giving nuclear a central role in doubling grid capacity by mid‑century. Ontario’s government has complemented this with direction to Ontario Power Generation to study new nuclear generation at the Wesleyville site, a location assessed as capable of hosting roughly 10 gigawatts of capacity—enough to power on the order of 10 million homes.^[1] Taken together, the federal and provincial signals are explicit: nuclear is expected to carry a significant share of Canada’s future baseload.

Canada is unusually well positioned to underpin such an expansion because it sits on the world’s third‑largest uranium resources and is already ramping up production.^[4] The Rook One project in Saskatchewan, newly approved after a long hiatus in green‑lighting uranium mines, is touted by the energy minister as capable of supplying up to 20% of global uranium demand once fully operational.^[5] If those production levels are realized, Canada would not just be self‑reliant in fuel; it would be a decisive node in international nuclear fuel security, particularly for the United States, which currently relies heavily on imports.^[8]

Domestically, nuclear already provides about 15% of Canada’s electricity, and the government is treating the sector as a jobs engine as much as a climate tool.^[3] Plans call for nuclear‑related employment to roughly double from around 90,000 positions today to more than 180,000, supported by new construction, fuel cycle facilities, and an expanded export footprint.^[3] Ottawa has backed that intent with capital, committing roughly $2.2 billion over ten years to nuclear expansion and innovation, including advanced designs and SMRs.^[5] That funding level is modest compared with total energy investment needs, but politically significant: it signals that nuclear has re‑entered the core of Canada’s industrial strategy.

SMRs and First-Mover Advantage

One of the most visible symbols of this new phase is the Darlington New Nuclear Project, which will deploy a small modular reactor (SMR) and make Canada the first G7 country to bring such a unit into grid service.^[5]^[10] The specific design, the GE Hitachi BWRX‑300, is intended to supply power for roughly 300,000 homes with a smaller physical footprint and a standardized, factory‑built approach that in theory should cut construction time and cost per kilowatt compared with bespoke gigawatt‑scale reactors.^[7]^[10] Canadian policymakers are betting that early SMR deployment can create an exportable template: a set of regulatory precedents, supply chains, and operating experience that other countries can adopt rather than learning on their own.

Internationally, SMRs occupy a peculiar space. The IAEA’s high‑case projections now assume that by 2050, global nuclear capacity could reach nearly 1 terawatt, with about a quarter of new capacity additions coming from SMRs.^[22] Yet historical base rates are sobering. Outside Asia, only a small fraction of announced nuclear projects actually reach completion, and global nuclear generation has been largely stagnant for two decades despite periodic bursts of rhetoric.^[23] In other words, Canadian SMR leadership could matter greatly—but only if these units are delivered broadly on time and budget, rather than repeating the pattern of decade‑long delays and multi‑billion‑dollar overruns that have plagued several recent large reactor projects.^[21]

AI, Data Centers, and the Return of Baseload

The most novel driver behind this latest nuclear push is not the climate crisis alone, but the extraordinary growth of AI and data centers. At a recent workshop convened by the Global America Business Institute and partners, energy and AI experts argued that data centers currently use on the order of 2% of world electricity, with demand plausibly rising toward 3–4% by 2030, and requiring at least 55 gigawatts of additional power capacity within just a few years.^[4] They emphasized a simple physical constraint: hyperscale AI infrastructure needs 24/7 power with high reliability, a profile that variable wind and solar cannot supply without massive storage and grid reinforcement, and that gas can supply but at the cost of greater carbon emissions and exposure to fuel price volatility.

Nuclear power, by contrast, inherently provides continuous output and is indifferent to weather, which makes it attractive as a backbone energy source for AI‑driven load growth. The same workshop underscored that while large reactors still take close to a decade to permit and build, SMRs and other advanced concepts could compress timelines, and several European countries that lack cheap gas or strong solar resources—such as the Czech Republic and Slovakia—are already treating nuclear as a strategic necessity.^[4] This is the backdrop against which Canada’s nuclear plans sit: not only decarbonization, but a global digital economy that is rapidly becoming as energy‑hungry as heavy industry.

Climate Imperatives vs. Deployment Reality

From a climate perspective, nuclear’s appeal is straightforward. Analysis of historical expansions in Sweden and France shows that once industrial capacity and regulatory competence are in place, nations have been able to add nuclear generation rapidly, displacing a significant fraction of fossil‑fuel electricity.^[25] The IAEA’s own climate‑focused work estimates that reaching its high‑case nuclear scenario would require investments in the range of $90 billion between 2024 and 2030 and about $125 billion per year thereafter, but would more than double operating nuclear capacity by mid‑century.^[2]^[22] Life‑cycle assessments generally find nuclear’s greenhouse‑gas footprint far below that of coal and gas, and similar in magnitude to wind; it typically exceeds solar, but the difference is modest relative to the gulf separating all three from fossil fuels.^[26]

Yet, globally, nuclear construction has not matched its theoretical promise. The World Nuclear Industry Status Report documents that between 2005 and 2024 there were 104 reactor startups and 101 closures worldwide, with more than half of the new builds in China alone.^[23] In the Americas, there are currently no new reactors under construction, and the number of countries with active nuclear building projects has fallen from 16 to just 11.^[23] Even with record nuclear generation in 2024, solar and battery capacity additions have been growing far faster, driven by sharp cost declines and shorter deployment cycles.^[23] Canada’s strategy thus runs against the grain of recent Western experience: it is trying to reignite a technology class that has stagnated outside a handful of state‑driven programs.

Cost, Timelines, and the Economics of Nuclear

Cost and time are the central economic constraints. Critics point out, with significant empirical support, that new nuclear plants in liberalized markets often require 10–20 years from conception to operation, and that capital cost overruns are common, forcing governments to rely on loan guarantees, production tax credits, and other subsidies.^[11]^[21] Such support is not unique to nuclear—renewables also benefit from policy incentives—but the scale and duration of nuclear support has sparked debate about whether resources would be better spent accelerating wind, solar, and storage instead.

Industry analyses, by contrast, argue that nuclear can be cost‑competitive with other forms of generation in systems without access to abundant cheap fossil fuels and that building multiple identical reactors on a single site can reduce per‑kilowatt construction cost by roughly 15%.^[17] Moreover, the economic calculus changes when reliability is priced properly: when grid planners value firm capacity and resilience to fuel shocks, nuclear’s dispatchability and long fuel cycles become assets rather than mere engineering curiosities. Canada, with its hydro backbone and cold climate, is precisely the kind of system where firm low‑carbon power has outsized value, which partly explains the country’s willingness to shoulder nuclear’s upfront costs.^[4]^[6]

The Waste Problem and Weapons Linkages

No issue in nuclear policy carries more emotive weight than waste. In the United States, over 80,000 tons of high‑level waste sit in interim storage, largely at reactor sites, because there is no operational permanent geological repository; Yucca Mountain never came online, and even its statutory capacity would be insufficient to handle all future waste.^[11]^[15] A 2026 Supreme Court ruling that allowed an above‑ground interim facility to proceed underscored the fragility of the national waste strategy rather than resolving it.^[15] These realities feed a narrative, advanced by groups such as Friends of the Earth and medical organizations like International Physicians for the Prevention of Nuclear War Canada, that nuclear waste is an unsolved problem after eight decades of production and that its radioactivity constitutes a novel planetary pollutant with uncertain long‑term effects.^[3]^[11]

Canada’s own strategy acknowledges the need for “world‑class” long‑term waste management, but does not yet point to a licensed, operational deep geological repository sized specifically for the waste burden from ten new reactors.^[6] Instead, it relies on ongoing processes led by the Nuclear Waste Management Organization, which has been working for years to select and license a DGR site. Until those decisions are final and construction is underway, critics will have a straightforward rejoinder: expansion without final disposal remains an open‑ended liability.

Waste also intersects with proliferation. Spent fuel and some reprocessing streams contain materials that can in principle be repurposed for weapons, and opponents argue that any global expansion of civilian nuclear capacity increases the volume of nuclear material that must be safeguarded, monitored, and protected against theft or diversion.^[11]^[3] In a world where Iran’s nuclear ambitions are already pushing the Middle East toward a potential regional arms race, and where AI‑driven military technologies may alter crisis dynamics, this linkage between electricity production and weapons risk is not merely theoretical.^[24]^[7] Policymakers therefore face a dual burden: designing waste systems that are technically secure and proving to skeptical publics that those systems genuinely reduce, rather than amplify, security risks.

War, Geopolitics, and Nuclear Anxiety

The psychological environment in which nuclear policy is made remains shaped by weapons, not reactors. Historical brinkmanship—from Khrushchev’s “missiles like sausages” era and tank stand‑offs in Berlin to Tsar Bomba tests—cemented an association between the word “nuclear” and existential threat. Contemporary scholarship shows that even advanced AI models, when placed in simulated war games, tend to escalate quickly to nuclear signalling; in one recent King’s College study, 95% of scenarios involved nuclear threats by at least one side.^[7] That is a telling measure of how deep the concept of nuclear escalation runs in strategic thought and, by extension, in public imagination.

Current tensions around Iran’s nuclear program, the emergence of informal blocs like CRINK (China, Russia, Iran, North Korea), and debates about NATO cohesion all occur against this backdrop of anxiety. Panels of former officials and scholars warn that failure to cap Iran’s ambitions could trigger a cascade of proliferation across Saudi Arabia, Turkey, Egypt, and beyond.^[24] For civilian nuclear projects in Canada or elsewhere, this atmosphere is both a curse and a constraint: it fuels opposition by conflating power reactors with weapons, but it also forces nuclear advocates to reckon seriously with governance, safeguards, and diplomatic context. Energy policy cannot be insulated from geopolitics when the underlying technology straddles both domains.

North America’s Nuclear Renaissance in Global Perspective

The recent announcement that both the United States and Canada intend to pursue ten new nuclear reactors each has been described as the biggest coordinated nuclear push in North America in decades.^[1] In Canada’s case, the plan is backed by a strategy, sites, and a clear role for uranium exports; in the U.S., the emphasis has been on federal financing and restoring industrial capacity.^[1] Both moves respond to the same pressures: AI‑driven load growth, climate commitments, and concern that China’s addition of roughly 34 gigawatts of nuclear capacity in the past decade compared with a single new U.S. plant has tilted the geostrategic balance.^[1]

Importantly, however, the global nuclear landscape is bifurcated. The IAEA’s projections show rising capacity under both high and low cases, and a growing role for SMRs.^[22] At the same time, independent status reports underscore stagnation and declining participation in reactor construction outside a cluster of determined states.^[23] Canada therefore sits at a crossroads. If it can execute its program with disciplined project management, transparent waste solutions, and realistic cost control, it could demonstrate that a liberal democracy can still deliver nuclear at scale in the 21st century. If projects stall or overrun, Canada will join a long list of countries whose nuclear ambitions were ultimately outpaced by economic and political friction.

What Will Decide Whether This Wave Lasts?

Looking ahead, three factors will decide whether the current nuclear wave endures. First, financing: nuclear requires large, patient capital. Public‑private structures that allocate risk sensibly and keep borrowing costs manageable are indispensable, especially as interest rates and competing investment demands fluctuate.^[2] Canada’s initial $2.2 billion commitment signals intent, but sustained, predictable frameworks will matter more than headline figures.^[5]

Second, regulatory competence and speed. Large reactors still have lead times measured in years; SMRs can shorten that, but only if regulators learn to treat standard designs differently from bespoke ones and if safety assessments are both rigorous and streamlined. Canada’s early SMR deployment will test whether such regulatory innovation is possible without compromising protection.^[10]

Third, social license. Waste management, proliferation concerns, and the memory of accidents like Chernobyl and Fukushima will continue to shape public attitudes. Evidence assembled by epidemiological studies suggests that, outside immediate disaster zones, long‑term radiation health impacts have been far lower than early fears and that nuclear’s death rate per unit of electricity is substantially below that of fossil fuels.^[26] That empirical record is powerful, but facts alone do not dispel fear. Governments and industry will need to pair technical performance with credible, independent oversight and honest communication if they want citizens to accept new reactors in their backyards.

Canada’s nuclear trajectory, framed by AI demand, war‑time energy insecurity, and climate pressure, encapsulates the broader dilemma facing advanced economies. The physics and geopolitics both favor some expansion of nuclear; the politics and project economics still resist it. Whether the world truly goes “back to nuclear” will depend less on declarations at COP or ministerial press conferences than on the quiet, demanding work of building reactors, managing waste, and proving over decades that this technology can serve as infrastructure rather than threat.

The Strategic Stakes for a Nuclear-Enabled Future

For a reader watching these developments from the vantage point of an energy‑hungry, digitally saturated economy, the stakes are straightforward. If nuclear expansion succeeds, it offers a pathway to reconcile relentless AI and data growth with serious climate policy, while reducing exposure to gas price spikes and geopolitical fuel disruptions. It could enable new forms of industry, from nuclear‑powered shipping and floating SMR plants to stable electricity for remote resource operations and urban centers alike.

If it fails—if projects falter under cost, delay, or public opposition—the burden of decarbonization will fall more heavily on renewables and storage, and AI’s energy appetite will be met largely by fossil fuels or a patchwork of regional solutions. Canada’s choices, and its ability to execute on those choices, will ripple far beyond its borders. In that sense, watching how one country navigates the hard realities behind a nuclear “renaissance” is not a parochial exercise; it is a way of gauging whether the world can align its digital ambitions, climate responsibilities, and security anxieties around a technology that has been both feared and needed for more than half a century.
