Nuclear Plant: One of Europe’s largest nuclear power stations, the Gravelins Nuclear Power Station (Northern France) suddenly shut down this week. The reason was not a technical fault, but a huge herd of Jellyfish. According to the report of The New York Times, the EDF company, which operates this plant, said that three of the six reactors were closed before Sunday midnight. The fourth reactor also had to be closed on Monday morning.
No effect on security
According to the company, the filter drums of the pumping stations of the Jailified plant got stuck in the drum. These parts fall in the non-east part of the plant. EDF clarified that it had no effect on security, employees or environment. Closing the reactors was part of the security system and now experts are trying to resume them safely.
Why does this problem happen after all?
Nuclear plants require large amounts of sea water to keep the reactor cool. Usually the screen debris and sea creatures in pipes prevent them from entering. But when the huge herd of Jellyfish reaches together, these screens are blocked by themselves. Not only this, due to 95% water of the dead jellyfish, it reaches within the system by changing a liquid state like gel and can cause problems inside.
Increasing heat and increasing number of jellyfish
Gravelins power station is located on the banks of North Sea. The hot water released from here is used to raise fish in a commercial fish farm. Experts say that along with the rising temperature of the sea, the number of jellyfish is also constantly increasing.
Gelibish has become a global challenge
According to marine research institutes, the herds of Jellyfish are now visible more often than before and on a large scale. Reasons like overfing, climate change and coastal development are considered responsible. Many nuclear plants around the world have been affected due to gelibish before. In 2011, nuclear plants from Israel, Japan and Scotland had to be discontinued. In 2013, a reactor from Sweden was completely paralyzed by Jelifish.
