LONDON (AFP) - A nuclear power station in eastern Scotland had to shut down its reactors after "high volumes" of jellyfish were found on its seawater filter screens, the operating company said Thursday. "Both units at Torness power station were manually shut down on 28 June, due to the high volumes of jelly fish fouling the cooling water screens," said a statement from EDF Energy, which runs the power station near Dunbar. It explained that the shutdown was purely a precautionary measure and insisted that "at no time was there a danger to the public", nor had there been any impact on the environment.
