Jellyfish Swarm Forces Shutdown of French Nuclear Plant

A massive jellyfish swarm shut down four reactors at France’s Gravelines nuclear power station, one of the largest in Europe. The swarm clogged cooling water intake filters, forcing an automatic shutdown and affecting power for millions. While authorities say safety was never at risk, such jellyfish disruptions have hit power plants worldwide—from the US to Japan—raising concerns about a growing global challenge as warming waters fuel bigger blooms.
