Startup Proposes Nuclear-Powered Data Center Complex on Utah Public Land

A startup called Valar Atomics has proposed building a massive data center complex powered by nuclear energy on public land in Utah, according to the company's plans.

The proposal calls for placing more than 450 nuclear reactors across more than 9,500 acres, an arrangement the company says would provide the substantial and consistent power supply needed to run large-scale computing infrastructure.

The project reflects a broader trend among technology companies and energy startups seeking new power sources to meet the rapidly growing electricity demands of data centers, which are increasingly used to train and run artificial intelligence systems.

Regulatory and community questions ahead

Any project of this scale would require extensive federal and state regulatory review, including assessments tied to nuclear safety, land use and environmental impact, before construction could begin on public land.

Details on the specific reactor technology involved, the project's cost, and its expected timeline were not immediately available. The scale of the proposal — hundreds of reactors across thousands of acres — would represent one of the largest nuclear-power buildouts associated with the data center industry to date.

Public land management agencies typically require lengthy environmental review processes for projects of this size, and it remains unclear how long approval could take if Valar Atomics moves forward with formal applications.
