The Counter-Drone Drill
D-FEND SOLUTIONS BLOG
In the ever-evolving landscape of security threats, critical infrastructure sites like nuclear facilities face an increasingly complex challenge: commercially available drones. Once viewed as mainly recreational devices, these versatile platforms now pose a potentially significant security risk.
This blog post explores the growing threat of unauthorized drone activity around nuclear facilities and discusses effective strategies for implementing effective drone defense systems.
Nuclear facilities encompass a range of vital national assets, including power plants that generate electricity, research institutions focused on nuclear science and engineering, reprocessing plants for recycling nuclear materials, and secure storage sites for nuclear waste.
Additionally, some facilities are responsible for the development and maintenance of nuclear weaponry. Each of these facilities requires stringent security measures due to the hazardous nature of the materials housed within and the critical role they play in energy production and national security.
However, the growing accessibility of drones introduces a layer of complexity to safeguarding these facilities. Drones can bypass traditional ground-based security measures, potentially:
Under the Freedom of Information Act (FOIA), the UK has recently revealed multiple drone sightings near British nuclear facilities from 2021 to 2023. While specific locations were withheld for national security reasons, the report provides valuable insights into the nature and frequency of these occurrences.
2021: Ten episodes were recorded, including unauthorized drone flights that led to alarm activations and substantial searches, although no substantial threats were detected.
2022: Nine incidents were reported, including a particularly alarming report from a pilot about a drone sighted at an extraordinary altitude of 20,000 feet.
2023: Through August, there were six drone sightings, mostly followed by thorough but unsuccessful searches.
The Ministry of Defence Police has maintained confidentiality over specific details of these incidents. This discretion underscores the seriousness of these drone sightings and the critical need for stringent security measures at such sensitive sites.
Between 2015 and 2019, the U.S. witnessed a disturbing rise in drone activities over nuclear sites, with at least 57 drone incursions reported across 24 facilities, according to data obtained through the Freedom of Information Act (FoIA). This series of incidents highlights significant ongoing challenges in securing critical infrastructure against new technological threats.
Notably, the Palo Verde Nuclear Power Plant in Arizona—a major facility contributing approximately 35% of Arizona’s total power output—faced several security breaches during this period. Reports detail multiple incidents where small groups of about five or six drones were observed flying around the plant’s three-unit site. Security personnel observed but could not respond as the drones carried out their incursions before disappearing.
France has witnessed a series of unidentified drone flights over several of its nuclear facilities, sparking considerable concern due to the strategic importance and high security of these sites.
Électricité de France (EDF), the state-run power firm, reported that drones were spotted over seven nuclear plants, including facilities in operation. The sightings occurred primarily at night or early in the morning prompting EDF to file multiple complaints with the police.
These incidents have not impacted the safety or operation of the plants, according to EDF. However, the pattern of flights—especially the simultaneous drone activity over four plants—suggests a coordinated effort that could signify a significant security threat.
As demonstrated in the incidents discussed above, drones can bypass conventional ground-based security measures making them a serious threat. The repercussions of unauthorized drone activities in such sensitive zones are potentially severe. This reality accentuates the urgent need for comprehensive and robust drone defense systems.
Effective drone defense strategies are crucial for preserving the operational integrity of nuclear facilities, safeguarding sensitive information, and upholding public and environmental safety.
Currently, nuclear facilities have detailed and significant ground surveillance and detection systems. However, these should be augmented with a reliable drone detection system that provides early warning, including the drone’s flight path, place of origin, and the location of the drone pilot. This is critical not only for early warning of an incoming drone, but also to allow the Nuclear Site Protection services to develop their deterrence plan, and if required, to contact local police authorities to deal with the drone operator who is often several kilometers away from the site.
A crucial step in managing drone threats at nuclear facilities is the development of a comprehensive reporting protocol. This protocol is indispensable for documenting and swiftly addressing all drone sightings in a systematic manner. It involves setting clear guidelines on who should be notified upon the detection of a drone, tailored to the severity of the incursion. The protocol must also specify the information to be collected from observers, including the time of sighting, drone behavior and appearance, and its last known location. This information is vital for assessing threat levels and determining the appropriate response by security personnel.
With a robust reporting protocol in place, ongoing monitoring and assessment become fundamental to maintaining security at nuclear facilities. This process integrates advanced detection technologies, such as RF Cyber-Takeover systems, enabling the detection of unauthorized drones in real time.
Continuous monitoring facilitates the immediate identification of anomalies and potential threats, allowing for swift responses by authorized personnel. Additionally, data collected from these monitoring efforts are analyzed to detect trends and identify typical drone activity patterns, allowing for preemptive adjustments to defense strategies, and enhancing the facility’s resilience against existing and emerging threats.
As several nuclear facilities do not have policing powers outside of their protected areas, it is imperative that they can interact rapidly with local police departments for enforcement, ideally, sharing information about nuisance and nefarious drones and their operators.
The nuclear power industry prides itself on being risk averse to the point at which it ensures that there are sufficient redundancies in place to ensure the safety of both their operations and that of the public. Public safety is the number one concern of the nuclear industry. This level of safety will be further enhanced as regulations evolve to confront the rogue drone problem and support C-UAS protection around critical infrastructure sites such as nuclear facilities, defending them against the targeting of these facilities by nefarious drone operators.
Building upon a robust reporting protocol and continuous monitoring, RF Cyber-Takeover C-UAS technology serves as a critical component of the defense strategy. This advanced system empowers security teams to effectively manage and neutralize potential drone threats.
By taking control of unauthorized drones, the technology allows for these drones to be redirected without causing collateral damage or disruption. This approach is instrumental in maintaining the security of the facility, minimizing the risk of breaches, and protecting the integrity of the infrastructure.
