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.

What believers are saying

  • Google-TVA deal secures 50 MWe offtake for Hermes 2 by 2030.
  • DOE Nuclear Dominance program accelerates TRISO fuel supply by 2033.
  • BWXT partnership scales commercial TRISO production for deployments.

What critics are saying

  • Hermes 1 completion slips to 2029, delaying Hermes 2 operations.
  • TerraPower's 42-month Wyoming reactor steals Google data center contracts.
  • NRG PALLAS tests expose TRISO cracking, forcing NRC redesigns.

What makes Kairos Power unique

  • KP-FHR uses TRISO pebble fuel and Flibe salt coolant from Oak Ridge origins.
  • First NRC-permitted power-producing Gen IV reactor with Hermes 2.
  • Factory-built modules from Albuquerque campus enable modular SMR assembly.
