What happened

A sudden influx of jellyfish forced EDF to shut down three reactors at a plant in northern France.

Why it matters

In early August, heatwave and jellyfish left a fifth of France's nuclear capacity offline.

Common ground

The French government has authorised energy producer and supplier EDF (100% owned by the state) to begin preparatory work for the construction of two future EPR2 reactors at the Gravelines nuclear power station in the Nord département.

Perspective signals
