Kairos Power

Designs, licenses, and demonstrates advanced reactors

Overview

Kairos Power designs, licenses, and demonstrates advanced nuclear reactors, headed by the KP-FHR which uses fluoride salt coolant and high operating temperatures to generate electricity. The system focuses on low water use and near-zero carbon emissions, pursuing an integrated path from design to regulatory licensing and demonstration to prove safety and economics. The company distinguishes itself by aiming to beat natural gas on cost and by a clear licensing/demo program coupled with environmental and grid-resilience performance. Its goal is to scale safe, affordable nuclear technology through government support, investments, licensing deals, and long-term service agreements to help decarbonize electricity.
