Could US Nuclear Reactors Survive Military Hits in Saudi Arabia?

The National Interest | Henry Sokolski

Saudi Arabia's proposed civilian nuclear program faces severe security risks from regional military strikes, potentially causing catastrophic radiological releases if facilities are targeted. A pending US-Saudi civilian nuclear cooperative agreement could soon clear the way for reactor exports, thrusting commercial energy infrastructure directly into a highly volatile regional war zone.

This development occurs amid a persistent regional pattern of targeting nuclear infrastructure, highlighted by a May 2026 Iranian drone strike on auxiliary generators at the United Arab Emirates' Barakah nuclear power plant. While passive defenses like cope cages and active air defenses can mitigate drone and missile threats, they remain ineffective against advanced penetrating ballistic missiles. The potential Saudi purchase of Westinghouse's AP-1000 reactor features containment structures hardened to 6,000 pounds per square inch. Penetrating warheads can bypass these barriers. A successful strike on spent fuel storage could force millions to evacuate, presenting severe long-term geopolitical and humanitarian consequences. Riyadh's nuclear ambitions thus introduce profound regional vulnerabilities.

Comment

The deployment of the Westinghouse AP-1000 reactor in the Middle East exposes a critical gap between civilian containment designs and modern precision-guided munitions. While the AP-1000 features a reinforced containment dome, its 6,000 pounds per square inch rating is mismatched against modern kinetic threats. Active air defences, such as Patriot PAC-3 batteries, offer only partial mitigation against high-velocity ballistic trajectories. This technological deficit shifts the safety of the Al Dhafra or Riyadh sites from passive structural resilience to continuous, high-readiness tactical interception.

To resist dedicated bunker-busting munitions, containment facilities require ultra-high-performance concrete rated up to 40,000 pounds per square inch. However, the application of such advanced materials remains cost-prohibitive and structurally complex for large-scale commercial reactor domes. Consequently, even highly fortified AP-1000 spent fuel pools remain vulnerable to specialized kinetic penetrators like the GBU-28.

Strategic Question for Discussion

If the AP-1000 reactor containment structure cannot be realistically hardened against kinetic penetrators like the GBU-28, does the security of these facilities depend entirely on the interception rates of active air defences like the Patriot PAC-3, or does it introduce an unacceptable single point of failure?

The available evidence points toward an unavoidable reliance on active interception, as passive structural hardening alone cannot defeat modern precision-guided kinetic penetrators. My assessment is that this dependency elevates the strategic value of air defence networks like the Patriot PAC-3 to a critical point of failure, where even a single leakage rate of one percent could result in a catastrophic radiological release. Consequently, the operational viability of these nuclear sites becomes hostage to the adversary's saturation capacity rather than the plant's physical resilience.
