Google Inks Deal with Kairos for Nuclear Micro-Reactor Powered Data Centers

Scheduled to be operational by the decade’s end, these nuclear micro-reactors represent a shift in energy procurement for tech giants, with Google joining the likes of Microsoft and Amazon. These companies have also turned to nuclear power to meet their substantial electricity needs. For instance, Microsoft recently engaged Constellation Energy to rejuvenate a previously closed reactor at Three Mile Island, and Amazon is establishing a massive data center linked directly to a nuclear facility in Pennsylvania.

Kairos Power aims for a 2030 completion of these reactors, slightly ahead of its initial “early 2030s” timeline, as reported by the U.S. Department of Energy. The company is part of a growing sector focused on developing small modular reactors (SMR), which are anticipated to be less costly and quicker to construct than traditional nuclear power plants.

Unlike conventional reactors that use water for cooling, Kairos’s innovative design utilizes molten salts, specifically a mix of lithium fluoride and beryllium fluoride. This approach has received approval from the Nuclear Regulatory Commission for a 35-megawatt demonstration reactor, marking a significant milestone for the startup.

Despite these advancements, Kairos faces numerous challenges, particularly in terms of economic feasibility and public acceptance. The economics of small modular reactors are yet to be proven as no commercial units have been commissioned to date. Moreover, public opinion on nuclear energy remains divided. While a majority supports nuclear power, there is considerable resistance against installing reactors in local areas, indicating potential hurdles in site selection and community acceptance.

As the deadline approaches, Kairos not only competes with traditional nuclear technology but also with emerging fusion energy companies, setting the stage for a critical period in the evolution of nuclear energy technology within the tech industry.
