Why did jellyfish shut down a French nuclear facility? An unusual tale of nature versus technology

AI Summary

A nuclear power plant in Gravelines, northern France, was temporarily shut down after a swarm of jellyfish clogged cooling system pumps. The automatic shutdown of four units posed no safety or environmental risks, according to EDF. The incident, caused by a massive influx of jellyfish, resulted in a full site shutdown as two other units were already offline for maintenance. EDF expects to restart the affected units on Thursday, assuring no power shortage risk. This isn't the first jellyfish-related nuclear plant shutdown, with similar incidents reported globally.
