Jellyfish prompt nuclear shutdown

It was spineless jellyfish, not politicians, that caused the shutdown in Sweden.

STORY HIGHLIGHTS

• Jellyfish in a cooling-water intake prompted reactor shutdown, company says
• The reactor is now operational again, according to numerous media outlets
• The Oskarshamn nuclear plant generates about 10% of Sweden's electricity

There's been another shutdown, but instead of spineless politicians, you can blame invertebrate sea creatures.

A large amount of jellyfish inhabiting a cooling-water intake at a major Swedish nuclear plant caused operators to manually shut down production at its largest reactor this week, according to OKG, the company that runs the plant.

"The operations management at unit O3 chose to disconnect the facility from the grid at noon on Sunday due to a large amount of jellyfish present at the cooling water intake," an OKG statement said. "This decision is a preventive safety measure in order for the unit to not be automatically shut down due to too-low cooling in the condenser."

OKG did not immediately return CNN calls seeking comment, but numerous media outlets reported that Oskarhamn Unit 3 was back up and running Wednesday.
