In a flurry of press releases, blog articles, and LinkedIn posts all released August 18, Kairos Power, Google, and the Tennessee Valley Authority announced a new power purchase agreement (PPA) between Kairos and TVA to supply up to 50 MW to the TVA grid, which powers two data centers owned by Google.

This agreement marks a significant milestone: It’s the first time a U.S. utility has entered into a PPA to buy power from a Gen IV reactor.

Kairos Power has received the go-ahead from the Nuclear Regulatory Commission to build its Hermes demonstration reactor at the Heritage Industrial Park in Oak Ridge, Tenn., making it the first non–light water reactor approved for construction in the United States in more than 50 years.

Kairos Power, an Alameda, Calif.–based advanced reactor developer, announced yesterday that it has been named to Cleantech Group’s list of the 100 most innovative and promising private companies in the cleantech sector for 2023. Cleantech Group is a research and consulting services firm headquartered in San Francisco.

Kairos Power has signed an agreement to produce TRISO fuel pebbles for the Hermes demonstration reactor at Los Alamos National Laboratory's Low Enriched Fuel Fabrication Facility (LEFFF) in New Mexico. Hermes is being deployed in Oak Ridge, Tennessee. The agreement was announced last week.

The Nuclear Regulatory Commission recently issued a draft safety evaluation report indicating initial acceptance of Kairos Power’s source term methodology for its fluoride salt–cooled high-temperature reactor (KP-FHR).
