Kairos Power Advances Modular Reactor Hardware with Engineering Test Unit 2

According to a recent LinkedIn post from Kairos Power, the company is progressing with Engineering Test Unit 2 (ETU 2), described as a non‑nuclear hardware demonstration focused on modular reactor construction. The post indicates that more than 30 modular equipment skids are being built in-house under factory conditions and assembled like building blocks in its Manufacturing Development Facility in Albuquerque, N.M.

The company’s LinkedIn post highlights that ETU 2 is intended to yield a fully standardized plant design based on prefabricated skids that can be transported by truck. The post suggests that lessons from ETU 2 in design, integration, and assembly will inform future reactor modules, which are planned to be fabricated in Albuquerque and shipped to Oak Ridge, Tenn., with ETU 2 operations expected to begin later this year.

For investors, the described activity may signal tangible progress along Kairos Power’s commercialization pathway, moving from concept toward repeatable, factory-based manufacturing processes. If successful, a modular and transportable design could enable lower capital costs, faster deployment timelines, and improved scalability compared with traditional nuclear projects, potentially strengthening the firm’s long-term economic proposition.

The focus on non-nuclear hardware testing also suggests a staged risk-reduction strategy, where engineering and construction challenges are addressed ahead of nuclear licensing and fuel use. This approach could help de-risk future project execution, enhance credibility with regulators and partners, and improve the company’s positioning in the advanced nuclear and small modular reactor market as commercialization efforts advance.
