Kairos Power

Kairos Power is an American nuclear energy company founded in 2016 that is developing fluoride salt-cooled high-temperature reactors (KP-FHR). The technology uses TRISO particle fuel and molten fluoride salt coolant, representing a departure from conventional water-cooled reactor designs. The company pursues a vertically integrated approach, encompassing reactor design, licensing, and manufacturing.

The company's Hermes 1 and Hermes 2 reactors, under construction in Oak Ridge, Tennessee, are the first non-water-cooled reactors to receive construction permits from the U.S. Nuclear Regulatory Commission (NRC). Kairos Power operates from three sites: its headquarters in Alameda, California; a Manufacturing Development Campus in Albuquerque, New Mexico; and the Reactor Demonstration Campus in Oak Ridge, Tennessee.

Technical domains at the company span nuclear reactor design, high-temperature reactor engineering, molten salt coolant systems, TRISO fuel manufacturing, and vertical integration manufacturing. The company's stated mission is to deliver clean, affordable energy to support the global clean energy transition.
