Nuclear Company – Kairos Power
Kairos Power is a mission-driven engineering company focused on the delivery of a clean, affordable and safe energy solution through the integrated design, licensing and demonstration of advanced reactor technology. Their mission is to enable the world’s transition to clean energy, with the ultimate goal of dramatically improving people’s quality of life while protecting the environment. In 2021, Kairos Power selected the East Tennessee Technology Park as the site for the Hermes demonstration reactor to support development of our fluoride salt-cooled, high-temperature reactor (KP-FHR) technology. Kairos Power received a construction permit from the U.S. Nuclear Regulatory Commission in December 2023 and commenced nuclear safety-related construction at the Hermes site in May 2025.
The Hermes 2 Demonstration Plant will build on lessons learned from the first Hermes reactor to demonstrate KP-FHR technology at a larger scale and supply clean electricity to the grid. The NRC issued construction permits for Hermes 2 in November 2024. The plant will be co-located with the Hermes demonstration reactor at Kairos Power's Oak Ridge campus.
In the coming years, the company will invest over $100 million and create more than 55 high-paying jobs in East Tennessee to support Hermes' construction and operations.
