Global warming poses unusual threats to nuclear power plants

Jellyfish Invasions Force Shutdowns at 3 Separate Nuclear Plants– MSNBC.com By Natalie Wolchover, 7 July 11, A nuclear power plant on the coast of Israel was forced to shut down this week when its seawater cooling system became clogged with jellyfish. A similar incident temporarily disabled two nuclear reactors at the Torness power station on the Scottish coast last week. A week before, a reactor in Shimane, Japan was crippled by yet another jellyfish infiltration.

Amid speculation that warm waters and ocean acidification — both driven by climate change — are boosting jellyfish populations, are these three incidents signs of a growing trend?…………

Some researchers do suspect that populations are rising, as jellyfish may thrive in warmer oceans. “Jellyfish populations spike and wane with climate variability, so it’s not hard to make the logical leap that if climate is changing long-term, we’ll likely see a population change,” Graham said. He is conducting research to investigate whether jellyfish populations are increasing globally, and if so, why.
