Jellyfish swarms have triggered the unexpected shutdown of France’s Gravelines nuclear power station for the second year in a row, disrupting energy production as cooling systems are overwhelmed by the marine intruders. Operators have repeatedly cited the jellyfish as the primary reason for halting operations, raising concerns over the plant’s resilience to environmental disruptions. The closures highlight growing challenges for nuclear facilities in coastal areas, where rising sea temperatures and shifting ecosystems may increase such incidents. Authorities are now assessing long-term solutions to prevent further interruptions.
It is the second consecutive year that jellyfish has forced the closure of the Gravelines power station in northern France.
