Greenpeace France on Tuesday crashed a drone dressed as Superman into the Bugey nuclear energy plant, located about 20 miles east of Lyon, to expose how vulnerable that facility is to a terrorist attack and highlight the broader dangers of this type of power generation.The activists told AFP that the drone struck \u0022a storage pool for spent nuclear fuel next to a reactor, one of the most radioactive areas at the site.\u0022\u0026nbsp;\u0022This is a highly symbolic action: it shows that spent fuel pools are very accessible, this time from the air, and therefore extremely vulnerable to attack,\u0022 Yannick Rousselet, head of Greenpeace France\u0026#039;s anti-nuclear campaign, said in a statement.Watch:Is it a bird?

EDF also claimed, \u0022The fuel building is key for security, designed in particular to withstand natural or accidental damage.\u0022Greenpeace EU, on Twitter, called EDF\u0026#039;s response \u0022worrying.\u0022Worrying repsonse from @EDFofficiel to @greenpeacefr\u0026#039;s action at the Bugey nuclear plant: they said they \u0022intercepted 1 of the 2 drones\u0022. Reality check: 2 drones were crashed on purpose... and there was also a remote control plane they didn\u0026#039;t even see... #SafetyFirst pic.twitter.com/P9wr5O7NuH— Greenpeace EU (@GreenpeaceEU) July 3, 2018France derives about 75 percent of its electricity from 19 state-controlled plants, according to the World Nuclear Association. Activists worldwide have repeatedly sought to draw attention to the dangers of this type of power generation—but particularly in France, where it is so prevalent.Last October, Greenpeace France activists entered another of EDF\u0026#039;s nuclear plants and set off fireworks. At the time, the group emphasized on Twitter, \u0022These installations are vulnerable.\u0022 AFP reports that in February, \u0022eight activists were sentenced to jail terms or fines\u0022 for participating in the firework action.
