Utah Coal Country Pushes Back on Valar's Nuclear Plan

TL;DR: Valar Atomics plans 456 small modular reactors in Utah's Carbon County to power a data center, per Grist, and many residents are resisting, according to High Country News. Valar is private, so you can't buy it. The useful signal for you is how hard it is to site, finance and build nuclear power for AI.

I spent years as a nuclear power plant operator on a fast-attack submarine, and as a quality assurance supervisor I signed off on more than 1,000 jobs. Nothing counted until someone verified it. A plan on paper is not a reactor, and 456 of them is a lot of paper. I covered the filing itself in our earlier piece on Valar's Project Beehive plan. This one is about the people in the way.

What is Valar planning in Carbon County?

According to Grist, the company plans a mega-complex of 456 small modular reactors on Bureau of Land Management land in the county. Grist calls the technology "still largely untested and unproven" in the United States. Separately, the Utah Trust Lands Administration agreed to lease a square mile of state land to Valar for up to 100 years. Staff told the board the site should generate $35 million in lease rents over 50 years, per the same report.

There is a second project nearby. Grist reports that Altigen, which builds natural gas plants for data centers, picked a 1,200-acre site east of Wellington for its "Jurassic Spark" project, nearly double the size of the Valar campus.

Why are locals resisting?

Carbon County has lived through a boom and a bust. Its coal mines produced nearly 10 million tons in 2006, and according to High Country News, not a single pound has been mined there since 2023. You might expect a county in that position to want any large employer. Many residents don't. They are asking who carries the risk of an unproven technology on their land.

For some, the word "nuclear" is personal. High Country News reports that Lupo's mother was 38 when she died, and Lupo believes the cause was downwind effects from radioactive weapons testing in Nevada during the 1950s.

State leaders are on the other side. Per Grist, Senator John Curtis and other high-ranking Utah officials welcomed Valar earlier this year, letting it test its Ward250 microreactor at the San Rafael Energy Lab in neighboring Emery County. A 30-megawatt AI data center is planned there with Nvidia. Which side wins, I can't tell you.

Why does this matter if you are an accredited investor?

Valar is private, and nothing in the reports I read describes an offering. So you can't join this as a deal. It is a data point on execution risk, which is where I always start: downside first.

The record for building nuclear on schedule is poor. A study cited by the Bulletin of the Atomic Scientists examined 180 nuclear power projects and found 175 had exceeded their initial budgets and timelines. Small reactors have their own history. Inside Climate News reports that NuScale's 2023 project in Utah for 12 modules and 600 MW fell through as costs kept increasing.

That last row matters for pricing. Inside Climate News notes this is still more expensive than wind and solar, which Lazard puts at under $40 to $86 per megawatt-hour. If you hold a fund with nuclear-linked power exposure, ask what cost per megawatt-hour its underwriting assumes.

What should you watch next?

Watch three things. Does the Trust Lands lease survive local opposition? Does the Nvidia-linked Emery County project get built at its planned 30 megawatts? And does the gas plant move faster than the reactors? If it does, gas carries the load for years. Our look at the gas and solar rush behind AI data centers covers why developers keep reaching for it.

Common mistakes

The first mistake is treating a filing as a financing. A plan for 456 reactors tells you what a company wants, not what anyone has funded. The second is reading state-level enthusiasm as permission, when the county and the neighbors still have a say. The third is chasing the theme without checking fees and lockups. Our overview of data centers as alternative investments lays out how funds package that exposure, and you should read the fee stack before the pitch.

FAQ

Can I invest in Valar Atomics? Not through anything in these reports. The company is private, and the coverage describes permitting and land leases, not an offering. Be wary of anyone who offers you access and calls it early.

Are small modular reactors proven in the U.S.? Grist describes the technology as largely untested and unproven in the country. Inside Climate News says two NuScale designs have NRC approval for deployment, out of 22 designs under development.

Why would data centers want their own power? Some developers plan generation next to the data center. Grist reports that Altigen builds natural gas plants for data centers and picked a 1,200-acre site east of Wellington, while Valar plans reactors for its own campus.

Before you put money behind any nuclear-for-AI story, pull the sponsor's stated cost per megawatt-hour and its schedule, and compare both with the overruns above. If the sponsor can't give you either, you have your answer. And if you want me to keep tracking how this one moves, subscribe to the free AIN briefing.
