"In fall 2007, workers at the Byron nuclear power plant in Illinois were using a wire brush to clean a badly corroded steel pipe — one in a series that circulate cooling water to essential emergency equipment — when something unexpected happened: The brush poked through. The resulting leak caused a 12-day shutdown of the two reactors for repairs. The plant’s owner, the Exelon Corp., had long known that corrosion was thinning most of these pipes. But rather than fix them, it repeatedly lowered the minimum thickness it deemed safe." (05/08/11)
