BBC: The Marcoule nuclear site in southern France experienced an explosion earlier today, in which one person was killed and four injured. Because it was caused by a fire near a furnace, the accident was deemed industrial rather than nuclear by the plant’s owner, national electricity provider EDF. According to Interior Ministry spokesman Pierre-Henry Brandet, there was no leak of radiation, either inside or outside the plant. And none of the injured workers was contaminated by radiation, said officials. All of France’s 58 nuclear reactors have been put through stress tests in recent months, following the March disaster at Japan’s Fukushima Daiichi nuclear plant, which was hit by an earthquake and a tsunami.
