Unexplained Drone Activity Over U.S. Nuclear Facilities
NRC records reveal dozens of mysterious drone sightings near critical nuclear energy infrastructure sites.
1Surge in Aerial Sightings
Between February 2024 and March 2026, facility operators filed 67 reports regarding unexplained drones near 28 nuclear sites across 17 states. These incidents, documented by the Nuclear Regulatory Commission, remain officially classified as closed and unresolved. The data highlights a persistent pattern of aerial activity targeting critical national energy infrastructure assets.
2Concentrated Activity Windows
A significant portion of these events occurred within a tight timeframe, with 33 of the 67 reported incidents taking place during an eight-week window between December 3, 2024, and January 24, 2025. Most sightings were recorded after dark, complicating identification efforts and raising questions about the operational intent behind these nocturnal flight patterns.
3Specific Site Vulnerabilities
Multiple high-profile locations reported repeated incursions, including Virginia's Surry Power Station, which experienced five separate incidents in December 2024. One notable event involved at least eight drones appearing in two distinct waves. Meanwhile, the Byron Nuclear Station in Illinois reported drone activity persisting for over two hours, indicating sophisticated and sustained operational presence.
4Proximity and Reactor Risks
The incidents involved close-range maneuvers, such as five drones flying approximately 100 feet above the 970-megawatt reactor building at River Bend Station in Louisiana. Such proximity to critical reactor infrastructure underscores the potential security risks. These reports were released following a freedom of information request filed by the publication The Liberation Times.
5Operational Security Challenges
Despite the frequency of these sightings, none of the records successfully identified a drone operator. Security teams at sites like Waterford, Connecticut, observed drones flying back and forth, yet the source of these vehicles remains unknown. The lack of attribution suggests a high level of operational security maintained by the unidentified parties involved.
6Historical Risk Assessments
A 2024 Nuclear Regulatory Commission paper referenced a 2019 analysis regarding drone threats. That study concluded that U.S. plants possessed no risk-significant vulnerabilities that adversaries could exploit with commercially available drones to cause radiological sabotage or theft of nuclear material. This assessment predates the recent surge in unexplained aerial activity across the country.
7Infrastructure Context
The reports include sites like the Three Mile Island facility near Middletown, Pennsylvania, where Constellation Energy plans to restart Unit 1 as the Crane Clean Energy Center. As these facilities undergo operational changes or restarts, the presence of unexplained drones adds a layer of complexity to the security protocols required for nuclear power generation.
8Implications for Future Security
The persistent nature of these drone incursions challenges existing security assumptions regarding nuclear site protection. With 28 sites affected across 17 states, the phenomenon is widespread rather than localized. Moving forward, the inability to identify operators or motives will likely necessitate a reevaluation of detection capabilities and airspace defense strategies for nuclear operators.
