Overview of Kairos Power

Kairos Power is a privately owned nuclear energy engineering, design, and manufacturing company singularly focused on the commercialization of the fluoride salt-cooled high-temperature reactor (FHR)

Founded in 2016 and headquartered in Alameda California 360+ Employees with a majority engineering and manufacturing

Kairos Power is pursuing a novel approach to nuclear development, highly informed by the success of SpaceX, that includes iterative hardware demonstrations and in-house manufacturing to achieve disruptive cost reduction and provide true cost certainty for commercialization

Our cost target objectives are set to be competitive with natural gas in the US electricity market

We are targeting a US commercial demonstration by 2030 (or earlier) and rapid deployment ramp in 2030s Kairos Power Headquarters Kairos Power Team

What?

A low power demonstration reactor that will prove Kairos Powers capability to deliver low-cost nuclear heat

Why?

Cost: Establish competitive cost through iterative learning cycles Supply Chain: Advance the supply chain for KP-FHR specialized components and materials while vertical integrating critical systems Design / Test: Deliberate and incremental risk reduction Licensing Approach: NRC will license Hermes as a non-power reactor and facilitate licensing certainty for KP-FHR Operations: Provide a complete demonstration of nuclear functions including reactor physics, fuel and structural materials irradiation, and radiological controls Operations Hermes will ultimately demonstrate the U.S. aptitude to license an advanced reactor in a timely manner Hermes Reactor ETU / Hermes KP-X / U-Facility
