KP-FHR
Kairos Power Fluoride salt-cooled High temperature Reactor
KP-FHR is Kairos Power's 140 MWe fluoride salt-cooled high-temperature reactor using TRISO pebble fuel.
It operates at 650°C with salt coolant for high efficiency and process heat. Design emphasizes factory fabrication and passive safety. Kairos has Google PPA for 500 MW by 2030.
Why it matters now
KP-FHR targets hyperscaler PPAs for reliable carbon-free power. NRC pre-application and Hermes demo progress key for 2026 licensing steps.
