🌎 The SMR shake-up #284

Small reactors, big power rankings

CTVC

Happy Monday!

Small nuclear startups are hitting milestones, but are they at critical mass? We’ve been tracking the big moves, and have a new leaderboard out now for the SMR space.

In deals, $11.4bn for AI data center across two deals, $230m for independent power production, and $200m for solid state transformers across two deals.

In other news, more tariff turbulence, the new US Farm Bill, and the new Octopus-California partnership.

Ranking the big names in small nuclear

Small modular reactors (SMRs) were catapulted into the spotlight late last year by massive raises, the second coming of SPACs, and high-profile partnerships with hyperscalers. But it’s a David and Goliath story: SMRs are being deployed first by major nuclear incumbents, while startups dominate the headlines by linking their solutions to the data center power crunch. 

Last week, two more developments continued the shakeup: SMR developer Nuscale reached final investment decision (FID) on its Romanian project, just the third OECD SMR project to reach FID and the largest capacity yet. Meanwhile, the NRC approved a partial construction permit for nuclear supply chain company Holtec for its project on the Palisades site in Michigan.

With so many milestones, tech nuance, and interest in nuclear for energy security, it’s difficult to cut through the noise and figure out who’s actually making progress. To give you a data-based, expert opinion, Sightline Climate created its SMR leaderboard, ranking the top 20 reactor vendors globally across four metrics: technology, deployment, finance, and supply chains.

Clients can see the full list on the platform here. CTVC is previewing the top 5 below, and you can read more on Sightline’s website here.

What’s included

This leaderboard shows which reactor vendors are furthest along the path to bankability, and will be updated every six months to capture all the moves in the space. The ranking considers credible licensing progress, the status of their real-world projects, availability of durable financing, and an executable supply chain. (It excludes the speculative likely economics or operational performance of different reactors.)

What you need to know

Despite last week’s milestones, OECD companies are still playing catch up. The early lead in small modular reactors belongs to Moscow and Beijing. Their state-owned nuclear bodies, CNNC and Rosatom, respectively, lead across almost every dimension Sightline tracks — technology maturity, available financing, and supply chain readiness. 

China’s CNNC sits at #1, as the owner of the only SMR currently in commercial operation anywhere in the world: the HTR-PM reactor. Its ACP100 is also the only SMR expected to reach operation in 2026. No Western vendor is close on either metric.

But excluding China and Russia, US vendors like TerraPower, X-energy, Kairos Power, and Oklo are climbing as hyperscaler offtake agreements and DOE support strengthen their finance and deployment scores.

Key takeaways 

  • Deployment and demand are early differentiators. CNNC has a slim lead thanks to its operational capacity, with TerraPower and GE Hitachi close behind due to larger order books.
  • The concentration isn’t as dramatic as it looks. After China and Russia’s dominance, the more consequential movement may be further down the table. Hyperscaler offtake and DOE support have materially improved the finance, deployment, and fuel outlook for TerraPower, X-energy, Kairos Power, and Oklo, accelerating their first projects. Large nuclear incumbents may have the benefit of capital and experience, but scrappy startup vendors are closing the gap.
  • Smaller players will need state support to compete. Nuclear incumbents are often owned or heavily funded by the state. To compete, startups and OECD players will need support from governments on capex funding, streamlining permitting, and ensuring firm offtake through procurement mandates.
  • Supply chains are make-or-break for novel technologies. Technologies that reuse existing designs and supply chains are currently leading, but we’re watching to see how capacity for novel fuels and components shape up over the next year. More firm capacity announcements and offtake timelines will tell us when startups can really start to scale.
