Jellyfish became a threat to France's Gravelines plant after clogging cooling systems
In a striking environmental incident, a massive jellyfish swarm has compelled the shutdown of reactors at France's Gravelines nuclear plant. The clogged seawater cooling systems have brought significant disruption to power generation. Following a related incident in 2025, the plant introduced enhanced monitoring and fishing strategies. This occurrence underscores the vulnerabilities faced by coastal nuclear installations amidst the challenges posed by extreme summer temperatures affecting France's nuclear output.
