Microreactor Market to Reach $6.8B by 2034 as University Demo Powers AI Node
Nuclear microreactor market will expand from $850 million in 2025 to $6.8 billion by 2034, with AI data-center power set to hit $2.1 billion by 2030. Elemental Nuclear’s University of Utah demo will convert 50 kW of reactor heat into 2–3 kW of electricity to run a mini AI node.
1. Market Forecast and Growth
Global nuclear microreactor market was valued at $850 million in 2025 and is projected to reach $6.8 billion by 2034, driven by remote electrification, defense uses and on-site AI compute needs. The broader nuclear-powered data-center infrastructure market could grow from $563 million in 2025 to $3.4 billion by 2035.
2. AI Data-Center Power Opportunity
AI training clusters require 50–200 MW of continuous power, creating a fast-growing niche expected to reach $2.1 billion by 2030. Hyperscale operators are exploring on-site microreactors to avoid grid connection delays of five to nine years and secure carbon-free baseload energy next to compute campuses.
3. Demonstration Project Details
Elemental Nuclear and the University of Utah plan to convert 50 kW of reactor heat into roughly 13 kW turbine output and 2–3 kW net electricity using a compact Brayton Cycle system. The demonstration will power a GPU-based AI node and validate small reactor viability for data-center deployment.
