Four of the six nuclear reactors at France's Gravelines nuclear power plant were shut down after an intake pipe used to draw water for cooling from a canal became clogged with jellyfish, Reuters reported.

Four of the plant’s reactors shut down after swarms of jellyfish clogged its pumping stations. It isn’t the first time the creatures have thwarted nuclear plants.

The Swiss government has presented draft legislation to end its ban on building new nuclear power plants, reversing a policy adopted in 2018 to phase out the technology.
