How AI-driven data center demand is triggering nuclear PPAs, SMR/microreactor projects, and grid-planning reforms

The interplay between AI-driven data center electricity demand and nuclear power generation continues to shape an increasingly complex and pivotal energy landscape. While recent trends indicate a near-term moderation in data center expansion, the strategic importance of nuclear energy—as the carbon-free, reliable backbone for continuous AI compute workloads—remains undiminished. Recent developments spanning advanced nuclear fuel licensing, uranium supply dynamics, policy reforms, and regional nuclear initiatives underscore a sector in flux, grappling with both unprecedented opportunities and emerging challenges.

AI Data Center Demand: Moderation, But Nuclear Remains Central to Future Growth

The insatiable electricity demands of AI workloads initially sparked a surge in nuclear power purchase agreements (PPAs) and accelerated plans for small modular reactors (SMRs) and microreactors. However, new reports from early 2026 reveal a softening in the pace of new data center construction, driven by:

• Rising construction and operational costs,
• Regulatory and permitting hurdles, and
• Community opposition in major hubs like Virginia and Texas.

The 1012 Industry Report (Feb 2026) highlights that some planned projects have been delayed or canceled, easing immediate grid pressure. Nonetheless, major tech players—including Microsoft, Meta, and Amazon—continue to aggressively pursue multi-gigawatt nuclear PPAs and co-located SMR developments, reaffirming nuclear’s pivotal role in providing the 24/7 low-carbon power essential for AI’s uninterrupted compute demands.

Advanced Nuclear Fuel and Uranium Supply: Breakthroughs Amid Tightening Markets

As nuclear deployments scale to meet AI-driven electricity needs, fuel supply chains tighten, prompting both breakthroughs and warnings:

• TRISO-X’s NRC License Approval (Feb 25, 2026)
  TRISO-X achieved a critical regulatory milestone by securing a Special Nuclear Material license for its advanced fuel fabrication facility. This accelerates commercial availability of TRISO fuel, a high-assay, accident-tolerant fuel designed for SMRs and microreactors, directly supporting near-term reactor deployments.

• X-Energy Advances HALEU Fuel Production
  Complementing TRISO-X, X-Energy’s progress in federal licensing for HALEU (High-Assay Low-Enriched Uranium) manufacturing enhances the fuel pipeline critical to advanced reactor commercialization.

• Uranium Supply Tightens with New Mines and Strategic Deals
  The Canadian government’s approval of its first uranium mine in two decades signals renewed confidence in domestic mining capacity. Kazakhstan’s Kazatomprom expanded long-term uranium supply agreements with India, aligning with India’s nuclear expansion ambitions to power its growing digital economy.

• Supply Gap Concerns and Geopolitical Tensions
  Centrus Energy’s CEO recently warned of a looming uranium enrichment supply gap that threatens the U.S. nuclear resurgence, a concern echoed by market analysts highlighting risks from delayed infrastructure and fuel availability.

  Meanwhile, geopolitical frictions persist: former President Donald Trump’s moves targeting Canadian uranium imports have raised alarms over potential disruptions to the U.S. nuclear fuel supply chain, which could complicate AI data center energy security and elevate fuel costs.

Market Dynamics: Investor Sentiment Shifts as SMRs Face Commercialization Hurdles

Wall Street is recalibrating its expectations amid the transition from nuclear hype to operational realities:

• NuScale’s Stock Decline Pre-Q4 2025 Earnings
  NuScale’s anticipated revenue drop to $8.76 million reflects the challenges facing SMR developers, including regulatory delays and the difficulty of converting project milestones into steady cash flow.

• Uranium Equities and Energy Suppliers Attract Renewed Interest
  In contrast, uranium mining companies and fuel suppliers have garnered increased investor attention, buoyed by concerns over supply constraints and strategic importance.

Demonstrations, Policy Reforms, and Regional Nuclear Initiatives Gain Momentum

Several key projects and regulatory reforms illustrate accelerating integration of nuclear energy with AI-driven grid needs:

• DOE and DoD Microreactor Airlift Success
  The first-ever airlift of a fully operational microreactor aboard a C-17 demonstrates rapid deployment capabilities for off-grid AI data centers and military applications, enhancing resilient, carbon-free power options.

• Romania’s NuScale SMR Final Investment Decision
  Romania’s recent FID on its first NuScale SMR project marks a European breakthrough, positioning the country as a regional clean energy leader supporting AI infrastructure growth.

• Floating Nuclear Plant on Track for 2028
  Plans for a 300 MW floating nuclear plant continue as scheduled, promising flexible, low-carbon power solutions for coastal AI data centers and isolated grids.

• South Korea Advances SMR Legislation Implementation
  The Ministry of Science and ICT has begun drafting enforcement decrees following landmark SMR legislation, signaling concrete national commitment to advanced nuclear aligned with emerging AI electricity demands.

• Regional Transmission Organizations (RTOs) Reform Capacity Markets and Tariffs
  PJM and other RTOs are overhauling capacity planning and interconnection processes to accommodate large AI data center loads without destabilizing the grid. Tariff reforms aim to equitably allocate costs for necessary grid upgrades amid growing political pressure from residential customers and utilities.

• U.S. State-Level Nuclear Ambitions Accelerate
  New state initiatives illustrate growing local support for nuclear expansion:

  • Illinois: Governor JB Pritzker’s Executive Order signals full-throttle state commitment to new nuclear projects.
  • Rural Utah: Communities express hope to benefit from the state’s nuclear ambitions, reflecting grassroots enthusiasm for nuclear-driven economic development.

AI-Enabled Nuclear Operations Drive Safety, Efficiency, and Licensing Advances

Artificial intelligence is increasingly embedded in nuclear operations, enhancing reliability critical for always-on AI workloads:

• Digital Twins Enable Predictive Maintenance
  Real-time reactor core and fuel condition monitoring through digital twins reduces unplanned outages, ensuring uninterrupted AI compute power.

• Machine Learning Accelerates Licensing and Risk Assessment
  AI-powered simulations streamline regulatory reviews by providing faster, more accurate safety evaluations, reducing deployment timelines and capital risk for SMRs and microreactors.

• National Lab Collaborations Foster Innovation
  Partnerships such as Idaho National Laboratory with NVIDIA optimize nuclear fuel performance via machine learning, while Oak Ridge National Laboratory and Australian counterparts pioneer “flowing” nuclear fuel concepts promising higher energy extraction and greater economic efficiency.
