Jellyfish vs. Nuclear Powerplants

By Anupum Pant

Nuclear power plants need have a massive intake of water to cool down their scorching hot interiors like fuel rods and turbines. So, they are preferably built near the coast where water can be sucked up from the sea in big quantities.

The intake valves located at the coast create a suction that can make tiny and simple, yet menacing creatures like jellyfish and sea salps can clog the pipeline very easily. Especially when there’s a group of them hanging around the intake.

This has caused several nuclear power plants around the globe to shutdown several times and is often detected when there’s a serious difference in pressure at the intake pipelines.

And probably many others around the world…
