Kairos Power and Samsung C&T Engineering & Construction Group signed an agreement under which Samsung C&T will invest up to $100 million in Kairos Power.
This funding includes direct cash and engineering services, meant to help build the Hermes 2 Demonstration Plant in Oak Ridge, Tennessee, pending regulatory approvals. The goal is to roll out Kairos Power’s fluoride salt-cooled, high-temperature reactor technology to help meet growing global energy needs.
A Major Investment in Advanced Nuclear Reactors

Samsung C&T is officially joining Kairos Power’s engineering, procurement, and construction team. This builds on an August 18 agreement that also included Barnard Construction.

“Samsung C&T’s investment and partnership reinforce the disciplined delivery model at the core of our commercialization strategy,” Mike Laufer, CEO and co-founder of Kairos Power, said. “We look forward to working with the Samsung C&T team to strengthen the integrated capabilities needed to deliver high-quality advanced reactors to customers with greater cost and schedule certainty.”
For the Hermes 2 project, the companies are splitting the work based on what they do best. Kairos Power will handle the reactor technology and the engineering and construction of the nuclear island. Samsung C&T will focus on the power-generation systems and the rest of the plant. Kairos will manage the overall project to keep it on time and on budget.
“Deploying advanced nuclear energy at a commercial scale requires strong, capable partners across the full project lifecycle,” Ed Blandford, Chief Technology Officer and co-founder of Kairos Power, added. “Our integrated EPC team brings together the complementary technology, engineering, manufacturing, and project-delivery capabilities needed to advance Hermes 2 and establish a foundation for broad deployment of KP-FHR technology.”
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.
