Microsoft Hires Industry Experts to Develop Nuclear-Powered Datacenters

Microsoft eyes nuclear power for datacenters, hires Archana Manoharan to lead efforts.


has appointed Archana “Archie” Manoharan as director of nuclear technologies, signaling the company's commitment to exploring nuclear energy as a sustainable power source for its . Manoharan, an energy industry veteran with over 15 years of experience, joins the tech giant coming from a notable tenure at Ultra Safe Nuclear Corporation (USNC), where she was instrumental in developing Micro Modular Reactor (MMR) technologies and engaged with the Department of Energy (DOE) loan program applications.

Last September we reported that  was actively seeking to hire a Principal Program Manager of Nuclear Technology. The new role to emphasize “maturing and implementing a global small modular reactor (SMR) and microreactor energy strategy” to power the company's data centers. This initiative follows Microsoft's procurement of Clean Energy Credits (CECs) from Ontario Power Generation (OPG) last year, which included power from traditional nuclear sources.

The Road to Nuclear-Powered Datacenters

In Microsoft's quest for alternatives for datacenters, the consideration of MMRs or small modular reactors (SMRs) plays a pivotal role. These reactors, characterized by their small output – up to 300 MW – and modularity, offer the potential for lower construction costs and increased adaptability compared to traditional large-scale fission reactors. Prefabrication and subsequent shipping to sites is a considered approach, aiming to streamline integration and affordability.

Microsoft anticipates that the deployment of these reactors, particularly to power datacenters, might span within a timeline of 10 to 15 years, suggesting a forward-looking stance on energy innovation. Additionally, Microsoft's recent agreement with Helion Energy reflects its broader strategy to invest in cutting-edge nuclear technologies, including the prospect of nuclear fusion. Helion Energy sets out to construct what could be the world's first operational fusion power plant, ambitiously expected to produce electricity by 2028 – although this timeline remains a matter of considerable skepticism within industry circles.

Carbon Neutral Goals and Expanding Energy Consumption

The integration of nuclear power into the datacenter space is driven by two pressing factors: the urgent need to reduce carbon dioxide emissions and the rising energy demands stemming from increased AI processing capabilities. With the announcement of Erin Henderson as the new director of nuclear development acceleration, who brings valuable experience from her position as general manager of transmission projects at the Tennessee Valley Authority, Microsoft underscores its strategy to not only decrease its but also to sustain its expanding infrastructure without relying on fossil fuels.

As the datacenter industry continues to explore innovative energy sources, Microsoft's approach aligns with a larger vision to empower organizations while also meeting global decarbonization efforts. With the recruitment of experts like Manoharan and Henderson, Microsoft is advancing its renewable energy initiatives, positioning itself as a leader in the transition to sustainable datacenter operations.
