Kairos Power has a mission to enable the world&rsquo;s transition to clean energy, with the ultimate goal of dramatically improving people&rsquo;s quality of life while protecting the environment.
We are an engineering company focused on the delivery of a clean, affordable and safe energy solution through the integrated design, licensing and demonstration of advanced reactor technology.
Growing from a broad research effort at U.S. universities and national laboratories, Kairos Power was founded to accelerate the development of an innovative nuclear technology that has the potential to transform the energy landscape in the United States and internationally.
Kairos Power is focused on reducing technical risk through a novel approach to test iteration often lacking in the nuclear space. Our schedule is driven by the goal of a U.S. demonstration plant before 2030 and a rapid deployment thereafter.
