Oh, One of France's Nuclear Reactors Is on Fire (Updated)

France, which draws 75% of its electricity from nuclear reactors, is currently using ten fire trucks to try to stop one of those reactors from being on fire.

The BBC reports "Fire crews have been rushed to a nuclear reactor in northern France after an escape of smoke," but that the reactor has been shut down and the company managing the plant claims "the site is secure." We'll wait and see. [BBC]

Update: Reuters reports the fires, "caused by hot oil leaking from a pump inside the reactor building," have been extinguished.

How is it that a water pump inside a nuclear reactor plant loses enough oil to start smoking? These water pumps are, to say the least, extremely important. At least if you don't want your plant to melt down.
