Next-Gen Nuclear Power: Valar Atomics Aims to Revolutionize Energy

USATue Nov 11 2025

Valar Atomics, a tech startup based in the Los Angeles area, is making waves in the energy sector with its advanced nuclear technology. The company has recently secured $130 million in funding, bringing its total funding to over $150 million. This investment round was led by Snowpoint Ventures, Day One Ventures, and Dream Ventures, with notable backers including Palmer Luckey, founder of Anduril Industries, and Shyam Sankar, CTO of Palantir.

A New Wave in Nuclear Power

Valar Atomics is not just another tech startup; it's part of a new wave of companies aiming to make nuclear power more accessible and efficient. The company's goal is to build thousands of advanced nuclear fission reactors within the next decade. To achieve this, Valar Atomics is focusing on creating small modular reactors that can be mass-produced and clustered at "gigasites." These sites could potentially power high-demand facilities like AI data centers and industrial manufacturers.

Milestones and Achievements

  • Construction Begins: The company has already begun construction on its first reactor in Utah and aims to demonstrate 100 kilowatts of thermal energy by July 4.
  • Legal Challenges: Valar Atomics is one of several nuclear startups benefiting from President Trump's push to accelerate advanced reactor deployment. The company has filed a lawsuit against the Nuclear Regulatory Commission, arguing that the current licensing process stifles innovation. Although the case has been temporarily paused due to the government shutdown, Valar Atomics expects progress soon following Trump's executive order on regulatory reform.
  • Pilot Program: In August, the Department of Energy selected Valar Atomics and other developers for a pilot program to deploy at least three advanced test reactors by July 2026.
  • Innovative Technology: The company's design uses helium as a coolant and operates at much higher temperatures than traditional plants. This technology is believed to deliver cleaner, more efficient, and factory-scale nuclear power.

Future Vision

Valar Atomics broke ground in September at Utah’s San Rafael Energy Lab, operated by the Utah Office of Energy Development. Its test reactor will serve as the foundation for the company's vision of building hundreds of small, high-temperature reactors on a single site. This approach could redefine how nations think about reliable power generation in the age of AI.
