Massive amounts of jellyfish have forced the shutdown of nuclear power plants in Japan, Scotland and Israel in the past few weeks.
All of these nuclear power plants use seawater to cool its reactors. Marine life is constantly being sucked in by the coolers, but now hundreds of jellyfish are invading the cooling systems causing the plants to be shut down.
The plants that have been shut down include the Orot Rabin Electric Power Station in Hadera on Israel’s west coast, the Torness power station on the south-east coast of Scotland and the Shimane plant in western Japan.
Jellyfish blooms are not uncommon in the summer but they have been an increasing concern for the ocean for quite some time. The sudden blooms can be due to warmer water temperatures, an increase in nutrients from fertilizers and overfishing.
