Palisades nuclear plant accident investigatedIt began with a light bulb.
Trying to fix a burned-out light bulb on an indicator button led to a serious incident that left the Palisades nuclear plant on Lake Michigan without half its electrical power on Sept. 25, 2011. A piece of equipment slipped while a worker was troubleshooting on a live electrical panel, causing an arc of electricity and a loss of half the indicators in the room that controls the reactor. Signals went haywire for a while. The plant shut down.
