ALAMEDA, Calif. — September 21, 2026 — Kairos Power and Samsung C&T Engineering & Construction Group (“Samsung C&T”) today announced the signing of a binding term sheet for Samsung C&T to make a strategic investment in Kairos Power and for the companies to collaborate on the commercial deployment of Kairos Power’s fluoride salt-cooled, high-temperature reactor technology (KP-FHR) to address rising global energy demand.
Samsung C&T has agreed to provide up to $100 million through a combination of direct investment and in-kind engineering services, subject to regulatory approvals, to enable the successful delivery of the Hermes 2 Demonstration Plant in Oak Ridge, Tennessee. The investment will further strengthen Kairos Power’s financial readiness as the company advances Hermes 2 and prepares for broader commercial deployment of KP-FHR technology.
In addition, Samsung C&T has agreed to join Kairos Power’s integrated engineering, procurement, and construction (EPC) team alongside other partners, providing expertise and capabilities to collaborate on selected engineering and constructability reviews to validate technical and execution readiness, initially focused on power-generation systems.
Kairos Power received construction permits from the U.S. Nuclear Regulatory Commission for the Hermes 2 plant in December 2024 and broke ground in Oak Ridge, Tennessee, in April 2026. The grid-connected, 50 MWe reactor will demonstrate KP-FHR technology at a relevant scale to mitigate technical, licensing, manufacturing, and construction uncertainty for the full-size commercial plants that will follow it.
In 2023, Kairos Power received the first U.S. construction permit for a non-water-cooled reactor to be issued in over 50 years. Kairos Power broke ground in April 2026 on the Hermes 2 Demonstration Plant in Oak Ridge, Tennessee, which will supply 50 MW of clean electricity to the TVA grid, under a multi-plant development agreement with Google.
