Nuclear Ambitions Face Regulatory Friction in Data Center Expansion

Data Center Knowledge covers SMR deployment in Texas, with insight from Bill Kosik, PE, CEM, LEED AP, on feasibility and timing challenges

Emerging energy technologies are constrained as much by policy as by engineering

The search for scalable, low-carbon power has pushed data center operators toward small modular reactors, particularly in regions where grid capacity lags behind demand. Yet the promise of nuclear innovation is colliding with the slower cadence of federal oversight and public scrutiny.

Bill Kosik, PE, CEM, LEED AP, Mission Critical Sector Leader at HED, offered perspective on the practical realities shaping SMR adoption. His comments addressed the gap between conceptual momentum and deployable infrastructure, noting the layered regulatory processes and extended timelines that complicate near-term integration into data center energy strategies.

In Data Center Knowledge, writer Matt Vincent examines a recent Nuclear Regulatory Commission intervention in Texas that challenges assumptions around how quickly SMRs can support hyperscale development. The article situates the debate within broader questions of permitting, risk, and long-term energy planning, highlighting the tension between urgency in the data economy and the deliberate pace of nuclear approval.

NRC Intervention Tests the Data Center Case for SMRs in Texas

The Texas SMR project’s regulatory setback highlights the financial and licensing challenges facing small modular reactors.

The promise of carbon-free nuclear power for data centers encountered a regulatory test this month, when the Nuclear Regulatory Commission’s Atomic Safety and Licensing Board (ASLB) allowed formal opposition to a Texas small modular reactor (SMR) project on financial-qualification grounds.

The ASLB’s decision to permit intervention against Dow and X-energy’s proposed four-reactor facility in Calhoun County, Texas, marks a critical moment for the nuclear industry, which has attracted billions in commitments from tech giants like Microsoft, Google, Amazon, and Meta. The ruling raises questions about whether SMRs can meet their ambitious timelines and cost projections at the scale data centers require.

What Are Small Modular Reactors?

SMRs are nuclear plants designed to generate roughly 50-300 MW of power per unit. Unlike traditional gigawatt-scale reactors, which are custom-built on-site, SMRs use standardized designs intended for factory fabrication and faster deployment. These qualities have drawn interest from technology companies aiming for commercial deployment by the early 2030s.

The Texas Challenge

The Texas SMR project, which would deploy X-energy’s Xe-100 SMR model, faced opposition from the against, which questioned whether the project’s backers had sufficient financial qualifications. Bill Kosik, sector leader for mission critical at architecture and engineering firm HED, told Data Center Knowledge that while ASLB’s move is not project-ending, it signals the scrutiny future SMR applications will face.

“While the project is still viable, it does raise concerns for future projects like this, including schedule and financial cost risks,” Kosik said. “It’s just another type of issue that will probably be raised in future reactor installations.”

Dow plans to host four X-energy XE-100 units at its Seadrift, Texas, site, for a combined capacity of 320 MW.

The Data Center Case for SMRs

The rapid growth of AI workloads has fundamentally changed data center energy requirements, creating step-function increases rather than incremental growth. In several regions, interconnection delays and transmission bottlenecks are slowing capacity expansion more than capital availability.

Kosik emphasized the importance of nuclear power in meeting greenhouse gas targets. “It’s not feasible to have the amount of renewable energy available to meet the greenhouse gas emissions targets without nuclear power,” he said.

Kevin Renninger of Montrose Environmental Group highlighted the scalability of SMRs, noting that their modular design allows operators to match energy output with demand growth without overbuilding infrastructure. Additionally, SMRs require significantly less land than most renewable energy sources.

Kevin Kong, CEO of Everstar, pointed out that SMRs offer 24/7 firm, carbon-free power with a small footprint and long-term price stability. Unlike solar and wind, SMRs provide consistent baseload power without large-scale storage, and compared with traditional large nuclear plants, they promise shorter construction timelines and lower capital commitments per module. “If AI load growth keeps outpacing grid buildout, nuclear becomes less of an interesting option and more of a strategic hedge,” Kong said.

Regulatory and Environmental Challenges

Nuclear power, by its nature, faces stricter regulatory requirements than non-nuclear energy sources. Renninger noted that many SMR designs aim for inherent safety improvements over traditional boiling-water and pressurized-water reactors and may reduce some radioactive waste-management challenges.

Mark Coates, vice president of Bentley’s Infrastructure Policy Advancement think tank, said that regulatory success depends as much on trust and consent as on engineering. “If you lose confidence with regulators, communities, or planning authorities, the project slows down or stops,” Coates said.

In the UK, the process includes reactor design assessment, site licensing, environmental permitting, and planning consent. The Generic Design Assessment evaluates reactor designs before construction but does not eliminate the need for site-specific permissions.

In the US, licensing remains a critical bottleneck. The Nuclear Regulatory Commission is developing Part 53, a performance-based framework tailored to advanced reactors like SMRs. This voluntary alternative to traditional regulations is currently expected to be finalized by March 27, 2026. While promising for the long term, it underscores the importance of regulatory clarity and timelines alongside technology readiness, Coates said. Operators should treat regulatory friction as a structural feature of the nuclear energy space.

The Path Forward for SMRs

The financial-qualification challenge in the Texas case shouldn’t necessarily deter data center operators from considering SMRs. Coates outlined five practical steps for operators and power partners to navigate the regulatory and operational landscape:

1. Engage Early. Begin discussions with regulators, planners, and communities early to build trust and address concerns proactively. Use plain language to explain safety, environmental, and resilience benefits.
2. Address Hard Topics Upfront. Tackle issues like waste management, emergency planning, water use, environmental impacts, and grid interactions directly and early in the process.
3. Build Realistic Commercial Structures. Treat SMRs like major infrastructure. Include milestones, off-ramps, and risk allocation in contracts, and avoid assuming licensing will be routine.
4. Design Holistic Power Systems. Plan for maintenance outages, backup arrangements, and grid interactions. Hybrid approaches that combine SMRs with renewables, storage, and flexibility are often more defensible on policy grounds because they address reliability and carbon together.
5. Maintain Near-term Decarbonization Efforts. While SMRs mature, continue advancing grid capacity, power purchase agreements, efficiency measures, and demand management to maintain credibility.

Beyond these steps, the broader challenge is transitioning SMRs from pilots to proven, repeatable infrastructure. According to Carmen Li, CEO of Silicon Data, the inflection point will come when SMRs demonstrate predictable deployment timelines and bankable financing structures.

“Power is becoming the limiting reagent in AI infrastructure expansion,” Li said. “SMRs are one potential solution, but they should be evaluated not just as a technology but as a long-term financial and regulatory commitment.”
