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.
Our fluoride salt-cooled high-temperature reactor closes the gap between vision and commercial viability. We're transforming the clean energy ecosystem by reimagining how advanced reactors are developed, built, and deployed at scale.
We build, test, and iterate, with thousands of hours of operational data to fine-tune our technology and eliminate uncertainty. With NRC permits in hand, the Hermes reactors are de-risking nuclear construction, the supply chain, and future operations for our commercial fleet.
