BRIDGMAN, Mich., July 31, 2013 – Indiana Michigan Power’s Cook Nuclear Plant Unit 2 returned to service at 8:19 p.m. Tuesday. The unit was taken off-line on Sunday morning.
The cause of the shutdown was a leak in the air supply line to an actuator on a steam supply valve. The valve closed when the air leaked out and water flow to the unit’s steam generators was reduced. Cook Operators took the appropriate action to take the unit off-line and the issue has been fully addressed.
Cook Unit 2 had run for 452 consecutive days leading up to the shutdown, 19 days short of the unit record of 471 days.
