The New York Times reports on how the world ends:
In an episode that evokes B-grade sci-fi movie plots, but actually reflects a continuing global problem, nuclear engineers in 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 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.
Nuclear power plants are often placed next to large bodies of water, so jellyfish clogs are a recurring problem. The plant had a similar episode in 2005.
The Oskarshamn nuclear power plant uses the same technology employed at Japan’s Fukushima Daiichi nuclear complex, where a powerful earthquake and tsunami in 2011 caused the worst nuclear disaster since Chernobyl.
