The Nova Scotia Wind Debate Goes Nuclear

For some, particularly older activist types, it's hard to understand any advocates for nuclear power, but new technologies mean some sane and reasonable communities are choosing the nuclear option.

What’s an SMR—and Why Are People Talking About Them?

SMR stands for Small Modular Reactor—a new generation of nuclear power that’s smaller, safer, and more flexible than the giant nuclear plants of the past.

A SMR should never be confused with ASMR… totally different.

Instead of building one massive, expensive nuclear station, SMRs are factory-built reactors that can be shipped, installed, and connected where needed—like energy Lego blocks. They’re designed with passive safety features, meaning they can shut themselves down without human intervention or external power. Think of it as nuclear reimagined for the 21st century.

Supporters say SMRs could provide clean, reliable electricity around the clock, without the emissions of coal or gas, and without the intermittency of wind or solar. Countries like Canada, the U.S., and the U.K. are investing in SMR development, and the first models are now under construction.

But the pitch isn’t perfect. Critics worry about nuclear waste, long-term costs, and the risk of repeating past mistakes. And some argue that we should focus on renewables we can build faster and cheaper.

Still, in a world racing to decarbonize, SMRs are gaining momentum as part of a diverse mix of low-carbon energy. Whether they succeed will depend not just on the technology—but on trust, transparency, and the choices Canada makes next.

How Do SMR’s Work?

Like so many engines. Ultimately. It’s a steam engine.

Are SMRs Readily Available in Canada Today?

Yes—small modular reactors (SMRs) are actively moving into commercial reality in Canada.

Ontario Power Generation (OPG) is already building the GE‑Hitachi BWRX‑300 at Darlington, set to produce ~300 MW (~300,000 homes) by about 2030, with four units planned—marking Canada’s and the G7’s first commercial SMR deployment.

Canada's SMR roadmap and vendor reviews (CNSC) indicate multiple SMR designs—like GE‑Hitachi, Terrestrial Energy’s molten salt designs, and Moltex SSR—are under active licensing and development.

Bottom line: SMRs are moving from concept to construction—but none are yet operational on the grid in Canada today. The first is expected to be operational by 2030.

To understand if SMRs are the answer, it's important that we know the question.

To understand if SMRs are the answer, it's important that we know the question.

Nova Scotia doesn’t just need electricity. We need a way to build lasting wealth from something we already have. Something rooted in our land, our sea, and our people.

If the question is, “What machine can we buy to power our homes?”—then maybe SMRs will do. They’re compact, clever, and quiet. But if the question is, “How do we build a future that belongs to us?”—then buying someone else’s machine, built somewhere else, with money that flows out as fast as the power flows in, won’t be enough.

We’ve spent too long being the end of the line, the place power gets sent to, not from. Offshore wind offers something different. It gives us a chance to build, to export, to own the work and the reward. Not just electricity, but an economy.

Do SMRs Present a Better Option Than Offshore Wind?

Let’s compare key dimensions:

1. Technology & Timing

• SMRs: First unit under construction, but grid connection likely by 2030.

• Offshore Wind: Proven global tech, with floating turbines rapidly scaling. NS’s wind resource is ready now.

  
  Advantage: Wind — speed and maturity.

2. Cost & Value

• SMRs: Initial costs ~C$6.1 billion per 300 MW; levelized cost estimated $214–319 CAD/MWh

• Offshore Wind: Global LCOE trends declining; NS’s Canada-specific estimates range C$105–113/MWh

  
  Advantage: Wind — cost-effective at scale.

3. Ownership & Wealth Creation

• SMRs: Likely manufactured elsewhere (OECD supply chain), with limited Nova Scotia content.

• Wind: Build-it-here: turbines, ports, service fleets, hydrogen gateways—local jobs and supply chain.

  
  Advantage: Wind — economic sovereignty.

4. Grid Integration

• SMR: Baseload power, good for stable supply—but single point of output, smaller in scale per unit.

• Wind: Intermittent, widespread; paired with storage or market exports, needs grid upgrades.

  
  Advantage: Context-dependent—wind scales but demands grid investment.

5. Environmental & Public Perception

• SMRs: Low emissions, nuclear waste management concerns, requires long permitting and Indigenous engagement.

• Wind: Low emissions, minimal waste, but subject to siting, wildlife, and NIMBY objections.

  
  Advantage: Even, depending on policy and public trust.

Latest Thinking & Factual Summary

• SMRs in Canada are real—OPG is building the first—but costlier on a per‑MWh basis and tied to external supply chains

• Offshore wind is cheaper, faster to deploy (globally proven), locally owned, and suited to Nova Scotia’s geography. It can scale into an export economy tied to hydrogen, supply chains, and interconnectivity —the physical and functional linking of electricity grids across regions, provinces, or countries so that power can be shared, bought, sold, or balanced between them.

Which One Is Better for Nova Scotia?

Our goal is sustainable, exportable wealth creation—not just energy.

• SMRs could help diversify energy, but cost more per unit and deliver limited local economic gain.

• Offshore wind offers scalable, cheaper clean power—and the opportunity to own the infrastructure, the jobs, and the returns.

For Nova Scotia’s needs—sovereignty, economic scale, and regional leadership—offshore wind wins on almost every metric. SMRs can play a supporting role in Canada, but they aren't a replacement for this chance to build something that’s ours and contribute to the Canadian project.
