French electricity group EDF announced today that three reactors at the Gravelines nuclear power plant in northern France have been forced to shut down due to a massive influx of jellyfish. Currently, only one of the six reactors at the plant is operating at full capacity, another is running at 50%, one is under maintenance, and the remaining three are offline due to the large number of jellyfish. EDF stated that the current situation does not pose a risk to the safety of the nuclear facility, the staff, or the environment. The Gravelines nuclear power plant also experienced a complete shutdown last year due to a large number of jellyfish entering the cooling system, and it took about three days before the first reactor was restarted.
