  Kairos Power is an Alameda, California-based advanced nuclear fission
  company developing the KP-FHR (Kairos Power Fluoride salt-cooled
  High-temperature Reactor), a Generation IV reactor design that uses
  TRISO (tri-structural isotropic) fuel pebbles cooled by molten
  fluoride salt (FLiBe) at low pressure and high temperature. Kairos
  Power is building Hermes, a low-power demonstration reactor at the
  East Tennessee Technology Park in Oak Ridge, Tennessee, which became
  the first non-light-water reactor authorized for construction by the
  U.S. Nuclear Regulatory Commission in over 50 years (construction
  permit issued December 2023). A second unit, Hermes 2, will pair two
  reactors with a 28 MWe electricity-generating turbine. In October
  2024 Google signed a corporate power purchase agreement with Kairos
  Power for up to 500 MW of nuclear electricity from multiple small
  modular reactors, with the first deployment targeted by 2030 and
  additional capacity through 2035 — the first corporate PPA for new
  advanced nuclear in the United States. The company's revenue model
  is reactor sales, electricity PPAs, and federal cost-share
  partnerships (DOE Advanced Reactor Demonstration Program). Kairos
  Power is privately held, does not expose a public developer API or
  SDK, and operates under NRC regulatory oversight as a
  safety-critical nuclear licensee.
