Jellyfish invaded the cooling water at a Scottish nuclear power plant this week. There were so many of these aquatic creatures floating around, the plant had to shut down.
The jellyfish are more than annoying, they pose a hazard to the cooling system of the plant. The nuclear reactors need unobstructed access to the cool sea water to keep them from overheating. A big pile of jellyfish stuck in the filters would seriously get in the way.
Plant workers are taking this jellyfish incident in stride. Most are doing odd jobs during this downtime, while others are stuck cleaning out those pesky Cnidarians. [Scientific American]
