World Nuclear News reported an update on Kairos' progress on constructing the Hermes low-power demonstration reactor in Oak Ridge, Tennessee. As a part of their construction permit application, the US company (co-founded by UCB Professor Per Peterson, Michael Laufer, and Edward Blandford), has submitted the preliminary safety analysis report (PSAR) for its fluoride salt-cooled, high-temperature reactor (KP-FHR) to the US Nuclear Regulatory Commission (NRC).
Kairos established a cooperative development agreement with the Tennessee Valley Authority earlier this year, and will collaborate with Materion Corporation, Oak Ridge National Laboratory, Idaho National Laboratory, and the Electric Power Research Institute on the development and demonstration for Hermes. The development is also supported over seven years by a US Department of Energy Advanced Reactor Demonstration Program cost-shared award.
World Nuclear News stated that along with Kairos, there are 6 other non-light water reactor designers that have formally notified the NRC of their intent to engage in regulatory interactions. Namely "General Atomics for the Energy Multiplier Module; X-Energy for the XE-100; TerraPower and GE Hitachi for the Natrium reactor; TerraPower for its Molten Chloride Fast Reactor; Westinghouse Electric Company for its eVinci micro reactor; and Terrestrial Energy USA for its Integral Molten Salt Reactor."
