"In an episode that evokes B-grade sci-fi movie plots from the 1950s, but actually reflects a continuing global problem, nuclear engineers in southeastern Sweden have been wrestling with a giant swarm of jellyfish that forced the shutdown of the world’s largest boiling-water reactor."
"The plant’s operator said that over the weekend, a huge cluster of moon jellyfish clogged the cooling water intake pipes at the Oskarshamn nuclear power plant on the Baltic Sea coast, forcing the complex’s 1,400-megawatt Unit 3 to shut down.
But Anders Osterberg, a spokesman for the operator, Oskarshamns Kraftgrupp AB, said Tuesday that the jellyfish had been cleared and that engineers were preparing to restart the reactor. The outlook was uncertain, he said."
