Nano Nuclear and Supermicro Want to Put Microreactors in AI Data Centers
AI data centers are consuming so much electricity that some companies are looking past the grid entirely. On May 6, 2026, Nano Nuclear Energy and server hardware maker Supermicro signed a non-binding memorandum of understanding to explore integrating compact nuclear microreactors with AI server infrastructure. The IEA projects global data center electricity consumption will roughly double from around 485 TWh today to 945 TWh by 2030 — and the companies are betting nuclear can fill that gap without waiting years for grid upgrades.
The reactor
The plan centers on Nano Nuclear's KRONOS MMR, a high-temperature gas-cooled microreactor designed to deliver around 15 megawatts of power. It is compact enough to be transported by truck, and the design targets 20-plus years of continuous operation without refueling. Supermicro's role would be to adapt its server platforms, storage systems, and — critically — cooling infrastructure to work alongside on-site nuclear generation. When power is produced at the source, waste heat from both the servers and the reactor can be managed in a single closed loop, potentially improving efficiency.
The pitch is grid independence: build a modular data center anywhere, add more server racks and another reactor module as demand grows, and never wait on a utility company.
The catch
This is an exploratory agreement, not a construction contract. The MOU is explicitly non-binding, and per TS2, Nano Nuclear's own filings warn the collaboration may never lead to binding deals or revenue-generating projects. The company has reported around $64 million in cumulative losses through the end of 2025 with no material revenue. US Nuclear Regulatory Commission design reviews for microreactor concepts remain in early stages, and realistic commercial deployment timelines sit in the early 2030s at the most optimistic.
The broader nuclear-for-AI trend is real. Microsoft restarted Three Mile Island under an 837 MW, 20-year power purchase agreement with Constellation. Amazon locked in a 1.92 GW, 17-year deal with Talen Energy near the Susquehanna plant. Meta has committed to sourcing 1–4 GW of new nuclear capacity. But those deals involve existing, already-licensed reactors — microreactors like KRONOS have yet to be commercially deployed anywhere.
What comes next
The Trump administration issued executive orders in May 2025 aimed at accelerating small modular reactor licensing, which could help compress timelines. Still, the gap between a signed MOU and a humming reactor under a server farm is wide. For now, this is a signal of where the industry wants to go — not where it has arrived.
