French police arrested 34 Greenpeace activists on Tuesday who forced their way into a nuclear power plant operated by EDF in Fessenheim, eastern France, the company said, reports Reuters.
The activists hung anti-nuclear banners from the plant, France's oldest in operation, but France's nuclear safety authority said they did not enter into its buildings and its security was not compromised.
The protesters used a truck to force their way into the site early in the morning, according to activists outside. Police gendarmes subsequently surrounded and entered the plant.
"Gendarmes have 56 activists under control and 34 have been arrested," an EDF spokesman said. "There has been no impact on the security of the plant, which continues to function normally."
President Francois Hollande has promised to close Fessenheim by 2016 and cut France's reliance on nuclear energy to 50 percent of its electricity mix from 75 percent now.
