Kairos Power’s reactor plans for Oak Ridge and beyondOAKRIDGER by Carolyn Krause 3/1/2025
Excavating land at the old K-25 site began last yearThis is the first of two stories on Kairos Power’s plans for building test reactors in Oak Ridge this decade and nuclear power plants next decade using two technologies based on Oak Ridge National Laboratory (ORNL) innovations.
Three construction permits from the U.S. Nuclear Regulatory Commission (NRC) for three proposed advanced nuclear reactors that will be cooled with molten salt instead of the water used in conventional reactors. A partnership with Google, which wants nuclear power as a reliable source of electricity for its power-hungry data centers to be used to test artificial intelligence chatbots and other models.
A completed excavation of an Oak Ridge site for the new reactors that will use uranium fuel, located where a gaseous diffusion plant once produced enriched uranium for nuclear power plants.
Those were some of Kairos Power’s achievements in the past year or so, starting in December 2023 when the first construction permit was granted to the company based in Alameda, California.
An update on Kairos Power’s progress in 2024 and timelines over the next decade for its advanced Generation IV nuclear reactor projects in Oak Ridge and elsewhere was provided by company officials during a recent Zoom call with a volunteer reporter for The Oak Ridger.
Edward Blandford, Kairos Power’s co-founder and chief technology officer, and Ashley Lewis, senior marketing communications manager, were on the call from California.
On Dec. 12, 2023, the NRC voted to issue a construction permit to Kairos Power for the Hermes Low-Power Demonstration Reactor. Kairos Power said that its first test reactor will show the company’s capability to deliver nuclear heat as part of its quest to provide safe, affordable, carbon-free nuclear power to meet growing demands for electricity and to delay climate change.
The 35-megawatt-thermal (35 MWt) high-temperature nuclear reactor, which will be cooled by a molten fluoride salt, was the first U.S. non-water-cooled reactor to receive a construction permit in more than 50 years. The company calls its concept the Kairos Power fluoride-salt-cooled, high-temperature reactor (KP-FHR) technology.
