Kairos Power IPO

Kairos Power is developing next-generation nuclear reactors using fluoride salt-cooled, high-temperature reactor (FHR) technology. Their approach combines the safety benefits of molten salt cooling with TRISO fuel particles, which are designed to retain fission products even under extreme conditions. The company is building a demonstration reactor called Hermes in Tennessee, scheduled to begin operations in the late 2020s, which will serve as a stepping stone to their commercial KP-FHR reactor design. Kairos has received significant backing from the U.S. Department of Energy and represents part of the advanced nuclear renaissance, focusing on smaller, safer reactor designs that could provide carbon-free baseload power. Their technology aims to address traditional nuclear concerns around safety and waste while maintaining the reliable, high-density energy output that makes nuclear attractive for grid-scale decarbonization.
