Kairos Power

Kairos Power's fluoride salt-cooled high-temperature (KP‑FHR) reactor technology is an advanced energy solution built for reliability, scalability, and robust inherent safety. Combining TRISO fuel with molten salt coolant in a compact, modular design, KP-FHR delivers affordable, carbon-free energy when and where you need it.

Kairos Power's commercial reactor is informed by thousands of hours of operational data. The compact unit is designed for modular deployment with a two-over-one plant configuration that balances complexity, efficiency, and cost.

Kairos Power's commercial plant is an efficient, reliable generation source that complements renewables, delivers affordable electricity for a range of applications, and supports future growth in a diverse energy portfolio.

Our approach is driven by strategic technology selection, enabling the use of conventional fabrication methods, off-the-shelf components, and in-house production to target costs competitive with natural gas. KP-FHR's passively safe design and optimized safety footprint reduce reliance on high-cost, nuclear-grade structures.

Our long-running engagement with the U.S. Nuclear Regulatory Commission (NRC) and demonstrated progress in siting and permitting advanced reactor projects are helping us de-risk licensing for the commercial KP-FHR fleet.

Our commercial-scale demonstration plant. The first electricity-producing Gen IV reactor to receive an NRC construction permit.

We've brought together key partners to support KP-FHR commercialization, forming a strategic alliance with industry leaders and giving them a front row seat to our iterative development process.

Kairos Power assembled a first-of-its-kind advanced nuclear alliance with North America’s leading nuclear utilities and generating companies to support KP-FHR technology development, licensing, manufacturing, construction, and commercialization.

Kairos Power and Google signed the world's first corporate agreement for multiple advanced reactor deployments, committing to develop a fleet of U.S. nuclear power projects delivering up to 500 MW of clean electricity by 2035.

By integrating a rapid iterative development approach with in-house manufacturing and pre-fabrication, we solve challenges early, gain a deep understanding of cost, and unlock more efficient, affordable construction.

Our mission is to enable the world's clean energy transition to improve people's quality of life while protecting the environment.

The world needs clean, reliable, and affordable energy now more than ever. At Kairos Power, we believe nuclear is an essential part of the solution. That’s why we take a focused approach to delivering it—building and testing real hardware and prioritizing learning at every step.

At this critical moment for U.S. energy, we're accelerating innovation to meet the challenge head on. The work is complex, but our objectives are clear: proving a new model for nuclear energy deployment, delivering with certainty, and making a positive impact on humans and the environment.

At Kairos Power, we’re united by our shared sense of purpose, driven by our mission, and grounded in our culture. We value innovation, accountability, and collaboration, believing that real progress comes from learning together. This mindset shapes not just how we work, but why we work: to build solutions to some of the world’s most pressing challenges.

Kairos Power began with a belief: nuclear is essential to a clean energy future. Today, we’re turning belief into reality. Through iterative development, in-house manufacturing, and deliberate innovation, our approach drives meaningful progress with unmatched momentum.

Kairos Power's footprint spans the U.S. We invest in the people and places that make innovation possible, helping us transform how clean energy is developed and deployed.

Our mission is clear, and so is our path forward. For those who prefer doing, we need the best minds-and the best teammates-to deliver the future of clean energy.
