The Kairos Power FHR (KP-FHR) is a novel advanced reactor technology that leverages TRISO fuel in pebble form combined with a low-pressure fluoride salt coolant. The technology uses an efficient and flexible steam cycle to convert heat from fission into electricity and to complement renewable energy sources.

The Kairos Power fluoride salt-cooled high temperature reactor (KP-FHR) is a novel advanced reactor technology that aims to be cost competitive with natural gas in the U.S. electricity market and to provide a long-term reduction in cost.

Kairos Power is pursuing the design, licensing, and deployment of a Fluoride Salt Cooled, High Temperature Reactor (FHR). The KP-FHR design relies on a combination of tri-structural isotropic (TRISO) particle fuel coupled with molten fluoride salt coolant.

2025年2月4日 · Kairos Power is an Alameda, CA company designing a fluoride salt-cooled high temperature reactor (FHR) using Triso-coated particle fuel in a pebble bed configuration. For more information, please see the Kairos pre-application documents (NRC Docket 99902069).
