For generations, Arizona鈥檚 firefighters have answered the call, training to run toward danger, not away from it, and preparing for the worst, often with limited resources and information about evolving technologies.

As interest in new advanced nuclear reactors such as small modular reactors, or SMRs, grows, some are beginning to ask whether local fire departments are prepared because SMRs are smaller, more advanced, and could be deployed in more locations?

It鈥檚 a fair question. The idea of responding to a nuclear-related incident does raise legitimate questions. Many fire departments, particularly in rural areas, operate with limited budgets, rely on mutual aid agreements, and do not have the advanced hazmat or radiological certifications necessary to respond to a fire at a nuclear site.

Add to that the fact that Arizona has not built a new nuclear plant in more than 40 years, since Palo Verde Nuclear Generating Station was constructed in the mid-1980s. Since then, entire generations have come and gone without ever having to think about the rigorous permitting requirements new nuclear plants must undergo to ensure public safety. And outside Maricopa County, most departments have never had to consider it at all.

But the evidence is clear: if a new SMR were sited in a rural county, no firefighter would be expected to walk into an unknown chemical or radiological hazard for which they were not prepared. 

SMRs are not the Cold War-era systems people associate with radioactive release or nuclear fallout. Advanced reactor designs like TerraPower鈥檚 Natrium reactor, X-energy鈥檚 Xe-100, and Oklo鈥檚 Aurora use passive safety features that make them effectively 鈥榤eltdown-proof鈥� and 鈥榳alk-away safe,鈥� virtually eliminating the risk of high-pressure explosions and radioactive plumes.

Nuclear facilities are among the most heavily regulated energy infrastructure in the county. Federal law requires every nuclear plant to maintain a fully dedicated, on-site fire brigade capable of handling fire, hazmat and radiological incidents independently.

10 CFR 搂 50.48 (Fire Protection), for example, requires plants to be equipped to respond to emergencies without relying on local jurisdictions. That鈥檚 why Palo Verde has its own on-site fire department with no mutual aid agreements with surrounding jurisdictions. It is not by choice. It is because federal law requires it, and federal law would require the same for new SMRs.

10 CFR Part 100 (Site Criteria) requires reactors to be located far from populated areas, at least 1.333 times the distance from the reactor site to the outer boundary of its low-population zone. Although this zone will be smaller for SMRs because they are inherently safer, locations will still be 3 to 5 miles or more beyond municipal boundaries.

10 CFR 50.47 (Emergency Planning Zone) makes clear that local jurisdictions participate in a purely supplemental off-site role, such as facilitating community coordination, evacuations, or sheltering in the event of an emergency. That demonstrates that local jurisdictions are not expected to enter plant operations or contaminated areas during an event, including for new SMRs.

In short, nuclear energy does not depend on local firefighters to manage complex on-site emergencies. It is designed, regulated and operated to be self-contained.

Arizona has a proven track record with nuclear energy. Palo Verde has safely powered our state for decades while supporting thousands of jobs and contributing billions to the economy.

Now, as we consider the deployment of new energy technologies, we have an opportunity to build on that success. Nuclear plants contribute millions annually in local tax revenue, which provides critical funding for local fire departments, including new fire trucks, upgraded fire stations, and state-of-the-art training facilities. They also provide hundreds of good-paying jobs, including for local fire departments and districts in rural areas.

With these new designs, Arizona鈥檚 fire departments and districts are being given an opportunity to benefit. Let鈥檚 take advantage of that.

The rules are in place. The technology is safe. And the benefits are real. Let鈥檚 move forward with confidence and ensure Arizona remains a leader in powering the future.
