Every once in a while, nature’s humbler creatures take on humankind’s technological behemoths.

The British tabloid The Sun is reporting today that jellyfish have clogged a filter screen at a nuclear power plant in Scotland. This forced a shutdown on Tuesday “with no threat to the public” (of course!). The plant is still shut down as the cleanup continues, with no word on when it will start up again.

And in New York, the Federal Aviation Administration ordered runway 41 at JFK International to be closed for a time yesterday morning, after several pilots reported a “turtle incursion,” with several turtles on the runway. The reptiles caused some delays, “but nothing serious” according to an FAA spokesperson. Ground crews were sent out to hurry them along.

This is getting to be an annual event at JFK, as the turtles climb out of Jamaica Bay to go lay their eggs in the sand on the other side of the runway.

It may not be a living creature, but a flooding river has a life of its own. Two nuclear power plants in Nebraska are being threatened by flood waters from the Missouri River. At the Ft. Calhoun plant, machinery there poked through an inflatable dam that had been set up around the reactor. Water poured into the electrical transmission room, forcing operators to switch to their emergency generators.

The plant has been shut down since April, but the reactor still needs power to keep the cooling system operating. Sounds a lot like Fukashima – but don’t worry! Nuclear Regulatory Commission chairman Gregory Jaczko toured the plant Monday, and afterwards a statement was issued stating that the public was “in no immediate danger.”
