Kairos
Project Overview
The U.S. Nuclear Regulatory Commission (NRC) is currenlty engaged in pre-application activities with Kairos Power starting in November 2018. 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).
To subscribe to the Kairos Fluoride Salt-Cooled High Temperature Reactor (HFR) email service choose Kairos Power HFR from the Advanced Reactors after scrolling to the Lyris subscription services section and entering your email on the NRC Listserv page.
