Kairos Power's customers, including major energy consumers like Google and communities seeking reliable, clean energy, face the significant challenge of transitioning away from fossil fuels while meeting escalating electricity demands, particularly with the rise of AI and data centers. The intermittent nature of many renewable sources like solar and wind also presents a hurdle for maintaining grid stability and providing consistent 24/7 power. This is why Kairos Power is dedicated to commercializing the Fluoride Salt-Cooled High-Temperature Reactor (KP-FHR), an advanced nuclear technology designed to provide a safe, affordable, and dependable clean energy solution. Our customers need an energy source that is not only carbon-free but also cost-competitive with natural gas and capable of complementing variable renewables to ensure a resilient and secure energy future.

The KP-FHR technology addresses these challenges by leveraging proven concepts like TRISO fuel pebbles and a low-pressure molten fluoride salt coolant. This innovative design enhances safety, as the reactor operates at near-atmospheric pressure, eliminating the need for massive, expensive containment structures typically associated with conventional nuclear power. This inherent safety, combined with a modular design, aims to reduce construction timelines and costs, making nuclear power more accessible and predictable. Kairos Power's iterative development approach, involving multiple design-build-test cycles with both nuclear and non-nuclear systems like the Engineering Test Units (ETUs), allows us to rapidly learn, mitigate risks in technology, licensing, manufacturing, and construction, and ultimately achieve cost certainty. Our commitment to vertical integration, including in-house manufacturing of critical components and fuel, further supports this goal of delivering an affordable and reliable clean energy solution to help our customers and the world transition to a sustainable energy future, dramatically improving people's quality of life while protecting the environment.
