Nano Nuclear and Tillman Digital announced a non-binding agreement to deploy up to 6 gigawatts (GW) of micro nuclear reactor capacity by 2040 to power artificial intelligence (AI) data centers across the United States. The partnership aims to supply low-carbon, reliable energy to meet the rising power demands of AI infrastructure operators, according to a report by Data Center Dynamics.
The agreement, formalized in early 2026, establishes a framework for deploying advanced micro nuclear reactors either adjacent to or within AI data center campuses nationwide over the next two decades. These reactors are engineered to provide stable, carbon-free electricity, addressing the rapid growth in data center power consumption driven by intensive AI workloads.
Nano Nuclear develops compact, modular nuclear reactor technology significantly smaller than traditional nuclear plants. This design allows flexible siting closer to major data center hubs. Tillman Digital, a leading data center developer and operator, intends to integrate this nuclear capacity into its portfolio of AI-focused data centers, reducing reliance on fossil fuels and grid electricity.
The planned 6GW capacity is equivalent to the output of roughly six large conventional nuclear reactors or dozens of utility-scale solar farms but offers the advantage of continuous 24/7 power generation unaffected by weather or daylight cycles. This scale marks one of the largest announced commitments to micro nuclear power in the AI sector to date.
The AI data center industry faces increasing scrutiny over its environmental impact and energy costs. AI workloads, particularly those supporting large language models and generative AI, demand vast computational resources, translating into higher electricity consumption. Data center operators must balance uptime, power expenses, and sustainability targets.
Nano Nuclear’s micro reactors are designed for high reliability and low emissions, addressing the need for dependable power while reducing carbon footprints. The reactors can be deployed incrementally, enabling Tillman Digital to scale capacity in line with AI workload growth, according to Data Center Dynamics.
While the agreement remains non-binding and subject to regulatory approvals, it reflects renewed interest in nuclear energy for data center applications. Historically, nuclear power has been underutilized in this sector due to concerns over scale, cost, and regulatory complexity. However, advances in micro reactor design and growing sustainability priorities have revived its appeal.
Traditionally, AI data centers rely on grid electricity sourced from a mix of fossil fuels and renewables. The intermittency of renewables and carbon emissions from fossil fuels have prompted operators to seek more stable and cleaner energy alternatives. Micro nuclear reactors offer a potential solution by providing constant baseload power with near-zero carbon emissions.
Tillman Digital’s CEO stated in a recent interview that integrating micro nuclear power aligns with the company’s long-term vision for sustainable data center operations. He noted that the partnership with Nano Nuclear would help meet increasing AI power demands without compromising environmental commitments.
The deal also aligns with broader trends in the energy sector, where advanced nuclear technologies are gaining attention as part of the clean energy transition. Both the U.S. government and private sector have increased funding and support for small modular reactors (SMRs) and micro reactors, recognizing their potential to complement intermittent renewables and reduce greenhouse gas emissions.
Nano Nuclear’s micro reactor technology is designed for factory-based construction and shipment to sites, which reduces construction time and costs compared to traditional nuclear plants. The reactors incorporate advanced safety features and passive cooling systems to minimize risk, potentially easing regulatory approvals and increasing public acceptance.
Experts caution that significant challenges remain before micro nuclear reactors become widespread in data center energy supply. These include navigating complex nuclear regulatory frameworks, securing financing, and building public trust. Nevertheless, the Nano Nuclear–Tillman Digital agreement signals growing confidence in the technology’s viability and relevance to AI infrastructure needs.
Beyond environmental and reliability benefits, micro nuclear reactors may offer economic advantages by stabilizing power costs over the long term. Energy price volatility has been a concern for AI data centers, where electricity can represent a substantial portion of operational expenses.
As AI technologies continue to expand, supporting infrastructure must evolve accordingly. Deploying micro nuclear reactors at scale could represent a significant step toward decarbonizing AI data centers and ensuring their reliable operation.
According to Data Center Dynamics, the partnership expects to advance through feasibility studies, site selection, and regulatory processes in the coming years, with initial deployments potentially starting in the late 2020s.
This deal highlights the increasing intersection between advanced energy technologies and AI infrastructure development, underscoring the growing role of innovative power generation solutions in the future of computing.
