Kairos Power Completes Fabrication and Installation of First Internally Produced Reactor Vessel for Engineering Test Unit

FOR IMMEDIATE RELEASE KAIROS POWER COMPLETES FABRICATION AND INSTALLATION OF FIRST INTERNALLY PRODUCED REACTOR VESSEL FOR ENGINEERING TEST UNIT ALBUQUERQUE, N.M. – January 30, 2025 – Kairos Power has successfully completed design, construction, and installation of the reactor vessel for its second non-nuclear Engineering Test Unit (ETU 2.0). It is the first reactor vessel to be fabricated in-house at Kairos Power’s Manufacturing Development Campus in Albuquerque, N.M. The reactor vessel is a central component of the Engineering Test Unit, which Kairos Power is building to advance the iterative development of its Fluoride Salt-Cooled High-Temperature Reactor (KP-FHR) technology. ETU 2.0 will demonstrate KP-FHR system integration in an optimized, fully modular design, building on lessons learned from its predecessor (ETU 1.0). A primary objective of the ETU program is to mature Kairos Power’s internal manufacturing capabilities, mitigating supply chain risk for the Hermes demonstration reactor series and Kairos Power’s commercial fleet. With ETU 2.0, the company is ramping up output of ASME U-stamped pressure vessels, advancing the production of specialized reactor components, and gaining proficiency in modular construction methods. To deliver the ETU 2.0 reactor vessel, Kairos Power established a dedicated shop inside its Albuquerque facility for KP-FHR vessel production, featuring large-scale...
