Over the period from 14 September 2014 to 16 November a total of 31 overflights by unmanned aerial vehicles – drones – had taken place at 19 French nuclear installations, 14 of which were nuclear power plant (NPP) sites. The motivation for and purpose of the drone flights remain a mystery. The overflights are unauthorised and blatantly flout the restriction orders for airspace above and around NPPs and, of course, there are very serious nuclear safety and security implications. In view of the mounting public concern EdF, along with the national security and nuclear safety authorities, has not been able to anticipate, detect and deter the drone flights, nor identify and restrain the human perpetrators from continuing with this activity.
