Jellyfish force partial shutdown of French nuclear plant

AI-summarized · Neutrality-checked

A massive influx of jellyfish forced the partial shutdown of the Gravelines nuclear power station in northern France after the creatures clogged the seawater filtration system used for cooling. EDF reported that units three, four, and six were closed, while units one and two operated at reduced power as a preventative measure. The plant, which features six units each capable of producing 900 megawatts, experienced similar disruptions in August of the previous year.

Consequences

The continued presence of jellyfish in the plant's cooling intake may necessitate ongoing operational adjustments or power reductions at the facility. EDF has already implemented mitigation strategies, including a partnership with local fishermen to remove jellyfish from the water, in an effort to maintain grid stability.
