Jellyfish Shut Down Swedish Nuke Reactor
It wasn’t a tsunami but it had the same effect: a huge cluster of jellyfish forced one of the world’s largest nuclear reactors to shut down — a phenomenon that marine biologists say could become more common.
Operators of the Oskarshamn nuclear plant in southeastern Sweden had to scramble reactor number three after tons of jellyfish clogged the pipes that bring in cool water to the plant’s turbines. It took workers over two day to clean the pipes of the jellyfish and engineers are preparing to restart the reactor, which at 1,400 megawatts of output is the largest boiling-water reactor in the world, says Anders Osterberg, a spokesman for OKG, the plant operator.
