PARIS — One person was killed and four were injured Monday afternoon in an explosion at a nuclear waste treatment site in southern France, according to the French Nuclear Safety Authority.
The authority and local police officials said there had been no radiation leak. About five hours after the explosion, the authority announced that the episode was over. The site, about 20 miles from Avignon, has no nuclear reactors, the authority said. A spokesman for the French power utility Électricité de France, which owns the site, said, “It is an industrial accident, not a nuclear one.”
