But here's one thing operators and security guards at America's nuclear energy plants and warhead storage sites will hope they don't catch a glimpse of tomorrow: a loud, hovering Superman imposter flying toward their facility.
Activists of the global non-governmental environmental organization "Greenpeace" explained his actions by a desire to prove that the building of nuclear power plants very vulnerable to external threats.
France derives about 75 percent of its electricity from 19 state-controlled plants, according to the World Nuclear Association. They targeted the facility's spent-fuel pool building, which can hold the equivalent of several reactor cores in concrete pools outside the highly reinforced reactor building.
"This action has once again demonstrated the extreme vulnerability of French nuclear installations, designed for the most part in the 1970s and unprepared for external attacks", the post says, according to a translation from the ABC.
EDF said that two drones had flown over the Bugey site, of which one had been intercepted by French police.
The current feat adheres to a collection of organized burglaries by Greenpeace protestors in French nuclear plants.
Back in October Greenpeace activists broke in and managed to launch fireworks over EDF's Cattenom nuclear plant, despite security barriers.
"The fuel building is key for security, designed in particular to withstand natural or accidental damage, which ensures its high degree of robustness", the company said, adding that it would lodge a complaint with police.
In October a year ago, Greenpeace activists breached security and launched fireworks over EDF's Cattenom nuclear plant.
Last week, 19 Greenpeace activists were handed suspended sentences for another incursion, this time at the Cruas power plant in the southern Ardeche region in November 2017.
Greenpeace's security breaches have sparked a parliamentary investigation into nuclear security, which is due to present its report on Thursday.
