Small Modular Nuclear Reactors Face Siting Hurdles in Iowa and Beyond
As demand for electricity surges from data centers and other large users, small modular nuclear reactors (SMRs) are emerging as a promising solution. But a key question remains: where will they go? In Iowa and across the country, local zoning battles and regulatory uncertainty threaten to slow the rollout of this next-generation energy technology, echoing the opposition that has stalled wind, solar, and natural gas projects.
The Promise of SMRs for Iowa's Energy Future
SMRs offer a flexible, low-cost, and emission-free alternative to traditional power plants. They take up less space and are designed with enhanced safety features. For Iowa, a state that values energy independence and agricultural productivity, SMRs could provide reliable baseload power without the land-use conflicts that plague wind and solar farms. However, as with any new infrastructure, siting remains the biggest obstacle.
Lessons from Wind and Solar Opposition
Renewable energy projects once enjoyed broad support, but that has changed. By early 2024, 15% of U.S. counties had enacted bans or moratoria on new wind and solar developments, according to a USA Today analysis. Local opposition, amplified by social media, has made it difficult to build anything new. In some cases, state legislatures have stepped in to override local restrictions, but the pattern is clear: public sentiment can shift quickly.
“When utilities suggested new natural gas turbines, opposition was just as strong,” noted Bret Dublinske, an attorney at Fredrikson & Byron P.A. who specializes in energy siting issues. “The lesson is that no technology is immune from local backlash.”
Iowa Counties Already Taking Action
In Iowa, several counties have adopted specific zoning provisions to regulate nuclear energy facilities. These measures aim to provide clarity without outright prohibition, but they signal that local governments are paying close attention. Dublinske pointed out that SMRs have one key advantage: federal preemption on radiological safety, which limits local control. But legal battles are already brewing.
In Arizona, the governor vetoed a bill that would have preempted local zoning for SMRs, calling for a more responsible regulatory framework. New Hampshire and Louisiana have launched task forces to study the issue. Indiana passed a law ceding permitting authority to the federal government, sparking debate over jurisdictional lines.
What SMR Developers Must Do Now
To avoid the same fate as wind and solar, Dublinske argues that SMR developers must engage early with local communities and regulators. “Energy advocates need to get a positive story out ahead of the inevitable disinformation,” he said. “They need to ensure a solid, workable legal framework exists that provides clarity and support.”
This means working with large-load partners like data centers to identify suitable sites, and proactively addressing concerns about safety, property values, and environmental impact. The debate is ramping up, and history shows it can escalate quickly.
Conclusion: A Critical Moment for Nuclear Energy
Siting has become a significant drag on other energy technologies. For SMRs to reach critical mass, the industry must learn from past mistakes and build a foundation of trust and regulatory certainty. Iowa, with its strong agricultural roots and growing energy needs, could be a proving ground for this new wave of nuclear power — but only if the right groundwork is laid now.
