A swarm of jellyfish has shut down a reactor at one of France's biggest nuclear power stations after swimming inside a series of filters in the water pumping station.

Electricity production at the Paluel nuclear plant in northern France was almost halved on Wednesday after the number 4 reactor was shut down and power at the number 3 reactor was reduced to protect infrastructure at the plant, according to a statement from provider EDF.

Newsweek contacted EDF for more information on the situation via email.
