Microsoft’s nuclear power plan for AI

Microsoft is considering powering its large language models and data centers with small modular nuclear reactors (SMRs), as revealed in a recent job listing. While SMRs are theoretically cheaper and more flexible than full-scale nuclear power stations, Microsoft faces several challenges in implementing this strategy. 

In addition to nuclear fission, Microsoft is investing in nuclear fusion, having signed a power purchase agreement with Helion, a fusion startup, with plans to purchase electricity from it by 2028. The tech giant faces rising power and water bills due to its growing AI infrastructure and data centers.

Microsoft’s ambitious move to power its AI infrastructure with nuclear reactors highlights the company’s dedication to tackling the environmental footprint of large language model training.
