Energy supplier EDF Energy plans to sue 29 protestors for trespassing at one of their French nuclear plants.

Hot on the heels of their climb up the Shard last week, protest group Greenpeace struck again today, targeting EDF’s Tricastic nuclear station in southern France.

Police arrested the activists after they had managed to unfurl a banner reading “Nuclear Accident: François Hollande, President of Catastrophe?” on the side of the power station (pictured). Other activists projected images of a ‘crack’ forming on one of its reactors.

EDF Energy said work at the plant had not been affected by the incident. In a statement, the French supplier said: “Activists have at no time been able to penetrate into the sensitive areas of the facility. This intrusion has had no impact on plant safety, or the safety of people on the site.”

Earlier this year EDF backed down from suing 21 English protestors for £5million after they broke into the West Burton gas plant in the UK and occupied it for a week. They decided against it following an online campaign which garnered around 50,000 signatures.

France generates more than three-quarters of its electricity from nuclear but recently French President Hollande has pledged to cut down the country’s reliance on the power source.
