Gravelines: A French nuclear power plant temporarily shut down on Monday after a massive and unpredictable swarm of jellyfish clogged its filters. The jellyfish blocked the cooling system at the Gravelines plant in northern France, causing four of its units to automatically switch off. According to Emirates News Agency, the site's two other units were already down for maintenance. Its operator, EDF, stated there was "no impact on the safety of the facilities, the safety of personnel, or the environment." The incident highlights challenges faced by coastal plants in managing marine life interactions.
