Jellyfish keep attacking nuclear power plants

Jellyfish Keep Attacking Nuclear Power Plants. Jellyfish are continuing to clog the cooling pipes of nuclear power plants around the world. GG, By Gabriel Geiger  3 Nov 21, Jellyfish are continuing to clog the cooling intake pipes of a nuclear power plant in Scotland, which has previously prompted a temporary shutdowns of the plant.

The Torness nuclear power plant has reported concerns regarding jellyfish as far back as 2011, when it was forced to shut down for nearly a week—at an estimated cost of $1.5 million a day—because of the free-swimming marine animals………

Like many other seaside power plants, the Torness plant uses seawater to prevent overheating. While there are measures in place to prevent aquatic life from entering the intake pipes, according to the Bulletin of the Atomic Scientists, they are no match for the sheer number of jellyfish that come during so-called “jellyfish blooms.”

“Usually, screens prevent aquatic life and similar debris from being drawn into the power plants’ cooling system,” the Bulletin of the Atomic Scientists wrote in a 2015 blog post. “But when sufficiently large volumes of jellyfish or other aquatic life are pulled in, they block the screens, reducing the volume of water coming in and forcing the reactor to shut down.” ……

“Any industry on the coast which uses seawater can find its operations complicated when seaweed or jellyfish blooms impact protective systems,” Angus Bloomfield, a marine biologist, is quoted as saying in a press release from the University of Cranfield. “They can damage machinery and even stop power generation, which could threaten stability of the electricity grid. An early warning system involving drones could allow industries in marine environments to act early and avoid the most dramatic effects these events can bring.” https://www.vice.com/en/article/epx4mj/jellyfish-keep-attacking-nuclear-power-plants
