"The bad valve was part of a residual heat removal system that cools the reactors after they shut down. The problem was discovered when the unit was being refueled in October, said Joey Ledford, a spokesman for the NRC regional office in Atlanta.

Also says the faulty valve was in place since the 60s since it was built. Good thing the tornados didn't hit this plant directly. Nevermind all the spent fuel...there's faulty valves too!
