Swarm of jellyfish shuts nuclear power plant in France

A massive jellyfish swarm clogged the cooling water intake at France’s Gravelines nuclear power plant, forcing all four reactors offline late Sunday. Three reactors shut down automatically, while a fourth was already offline for maintenance. EDF said there was no safety risk or impact on power exports. The North Sea–fed plant, which can power 5 million homes, joins a long list of coastal facilities worldwide — from Scotland to China — disrupted by sudden jellyfish blooms, The Guardian has reported. Scientists have been developing early-warning tools to predict such swarms.
