The Nuclear Company, a two-year-old startup, just bagged $51.3 million in a Series A round to build massive nuclear reactors using tried-and-true designs, sidestepping the hype around newfangled small modular reactors (SMRs). Announced on May 16, 2025, the funding, led by Eclipse with CIV, Goldcrest Capital, MCJ Collective, True Ventures, and Wonder Ventures, brings their total haul to $70 million. Here’s why this matters and what’s at stake.

What’s the Plan?

Founded in 2023 by Jonathan Webb (ex-AppHarvest CEO), Kiran Bhatraju (Arcadia CEO), and Patrick Maloney (CIV CEO), The Nuclear Company is sticking to existing reactor designs to avoid the regulatory and technical headaches of new tech. They’re eyeing fewer than a dozen U.S. sites with existing permits—think old coal plants or nuclear facilities—where they can break ground faster. Each site could handle reactors pumping out over 1 gigawatt (GW) of power, and the company’s aiming for a 6 GW fleet to start.

Why the rush? U.S. electricity demand is set to jump 16% by 2029, driven by data centers that could guzzle four times more power by 2030, per Grid Strategies. Tech giants like Google (teaming with Kairos for 500 MW of SMRs), Amazon (backing X-energy with $700M), Meta (seeking 4 GW), and Microsoft (reviving Three Mile Island) are scrambling for clean, steady energy. Nuclear fits the bill, but it’s not quick.

Why It’s a Big Deal

The Nuclear Company’s strategy is clever: use proven designs and pre-approved sites to cut costs and delays. Big reactors can churn out way more power than SMRs—6 GW is enough for millions of homes or dozens of data centers. Their Columbia, South Carolina, office, opened in April 2025, will create 100+ jobs to kick things off. But it’s not all smooth sailing. Nuclear faces stiff competition from solar farms, which are cheaper and faster to build (18 months vs. nuclear’s decade-long slog). Solar-plus-battery setups are stealing tech’s attention. Worse, a new House bill could ax nuclear’s $15/MWh tax credits from the Inflation Reduction Act, hiking costs. And with only 20 new U.S. reactors online since 1990, per the EIA, the industry’s track record for speed is shaky.

What’s Next?

The Nuclear Company’s reactors won’t hum until the early 2030s, which could miss the boat if data center demand spikes sooner. Still, their focus on big, permitted sites could make them a go-to for utilities and tech firms desperate for carbon-free power. If they pull it off, they could help nuclear reclaim its spot as a climate hero—9% of global electricity today, per the World Nuclear Association. But if solar keeps outpacing or subsidies vanish, these big plants might end up as costly dinosaurs.

Keep an eye on their site picks and how Congress handles nuclear funding. With 83% of Americans wanting clean energy, per a 2024 Pew survey, the pressure’s on to deliver.
