Around 30 Greenpeace activists climbed a fence at a nuclear power plant in France on Monday in what they say was an attempt to expose the flimsy security. EDF, France’s main electrical company, said the protesters did not get into any sensitive areas and production was not affected. Greenpeace France’s Yannick Rousselet called the plant, Tricastin, “one of the five most dangerous” in the country. Most of the protesters were arrested by 2:30 a.m. local time, but some were still clinging to metal structures and ladders. French President François Hollande has vowed to reduce the country’s dependence on nuclear power by 25 percent by 2025 and to close the oldest plant, but Hollande fired the energy and environment minister earlier this month for criticizing his budget.
