The cause of a cooling pump malfunction that forced operators to shut down the Unit 2 reactor at Byron nuclear plant is now under investigation.

Operators shut down the reactor manually just before 8 p.m. Wednesday after the cooling pump malfunctioned on a generator the served the non-nuclear area of the Byron Generating Station, said Neal Miller a spokesman for Exelon Generaton, which owns the plant.

He said the plant responded as expected, and the shutdown was performed safely. Unit 1 continues to operate at full power.

The plant is about 95 miles northwest of Chicago.

Last year, an electrical insulator failed and fell off a metal structure, interrupting power to Unit 2 and causing the reactor to automatically shut down. Officials fixed the problem and the plant resumed operations the next week.
