Hermes Mandatory Hearing - Over view Panel

MICHAEL LAUFER, CHIEF EXECUTIVE OFFICER PER PETERSON, CHIEF NUCLEAR OFFICER OCTOBER 19, 2023

Kairos Power s mission is to enable the worlds transition to clean energy, with the ultimate goal of dramatically improving peoples quality of life while protecting the environment.

Over view of Kairos Power

Kairos Power is a privately owned nuclear energy engineering, Kairos Power Headquarters 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 Kairos Power Team 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

Hermes Reactor

What? KP-X / U-Facility A low power demonstration reactor that will prove Kairos Power s capability to deliver low-cost nuclear heat

Why? Operations Cost: Establish competitive cost through iterative learning cycles ETU / Hermes 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

Hermes will ultimately demonstrate the U.S. aptitude to license an advanced reactor in a timely manner

Hermes Over view

Fluoride-salt cooled, high temperature reactor (FHR)

Pebble bed core with Tri-structural, isotropic (TRISO) fuel particles, graphite moderator/refle ctor

Reactor Thermal Power: 35 MWth

Coolant Operating Temperature:550°C - 650°C

316H stainless steel reactor vessel

Passive safety systems Shutdown elements insert via gravity D ecay heat removal system removes heat during postulated events without active components

Hermes Site

The site is located in Oak Ridge, Tennessee in Roane County within the East Tennessee Technology Park (ET TP)

The Hermes test reactor will be located on former Department of Energy gaseous diffusion plant (K-33) building site

The site boundary encompasses approximately 185 acres About 30 acres would be permanently disturbed for operations of the facility
