Kairos Power featured prominently this week as it advanced its Hermes 2 fluoride salt‑cooled high‑temperature reactor project in East Tennessee and underscored progress in materials testing. The private nuclear developer is positioning Hermes 2 as its first power‑producing unit and the initial deployment under its agreement with Google to supply clean power to data centers.

Hermes 2 is expected to provide up to 50 megawatts of electricity to the Tennessee Valley Authority grid, targeting decarbonization of data center operations in Tennessee and Alabama. Company commentary frames the project as a commercial proving ground for its advanced reactor design, project delivery capabilities, and a potential template for a replicable fleet model.
Kairos Power emphasized Tennessee’s role as a long‑term hub for nuclear construction and operations, citing an experienced, pro‑nuclear workforce and infrastructure around Oak Ridge. CEO and Co‑Founder Mike Laufer highlighted that this regional depth is intended to lower execution risk and support more predictable timelines and costs for Hermes 2 and future deployments.
On the technology front, the company reported significant progress in qualifying ET‑10 graphite supplied by Ibiden, machining nearly 3,000 specimens to tight tolerances for destructive testing. The work is aimed at de‑risking core reactor components for its Hermes design by validating key physical and mechanical properties, which could support future licensing and deployment efforts.
The developer also received the 28th National Award for Nuclear Science and History from the National Museum of Nuclear Science and History in Albuquerque. Kairos Power pointed to collaborations with Sandia National Laboratories, Los Alamos National Laboratory, and the University of New Mexico, as its Manufacturing Development Campus in New Mexico supports systems and components for future multi‑state deployments.
Across these updates, the company is combining project execution, supply‑chain and materials validation, and regional workforce strategy to strengthen its position in advanced nuclear and data‑center energy markets. Taken together, the week’s developments underscore growing institutional recognition and incremental de‑risking of Kairos Power’s pathway from demonstration to commercial power production.
