Massive Jellyfish Swarm Halts French Nuclear Power Plant

A massive jellyfish swarm forced the shutdown of France's Gravelines nuclear plant after clogging cooling systems. Operator EDF confirms no safety risks while specialists assess the situation. Scientists link the unprecedented bloom to warming North Sea temperatures.

Unprecedented Jellyfish Invasion Forces Nuclear Shutdown

France's Gravelines nuclear power plant experienced an emergency shutdown today after an enormous swarm of jellyfish infiltrated its cooling systems. Located between Calais and Dunkirk, this facility is one of France's largest nuclear sites with six reactors.

Incident Details

The jellyfish bypassed initial filtration systems due to their gelatinous composition before clogging critical filter drums in the seawater cooling intake. This caused automatic safety systems to trigger, shutting down four reactors. With the remaining two reactors already undergoing maintenance, the entire facility ceased operations.

Safety and Environmental Impact

Plant operator EDF confirmed the shutdown posed no safety risks to personnel, facilities, or surrounding communities. Specialist teams are conducting inspections and necessary repairs. Marine biologists attribute the unprecedented jellyfish bloom to rising North Sea temperatures, which accelerate jellyfish reproduction cycles.

Broader Implications

This incident highlights infrastructure vulnerabilities to climate change. Similar jellyfish-related disruptions have occurred at coastal power plants in Japan, Sweden, and Israel. Experts warn such events may increase as ocean temperatures continue rising.
