Byron Nuclear Power Plant Back On-line

Operators at Byron Generating Station returned Units 1 and 2 to
service on Wednesday, October 31.
Both units were taken off line on Friday, October 19, to repair a water pipe leak caused by external corrosion. During an inspection, workers discovered the small leak as they prepared the pipe for
ultrasonic testing, which is a method used to test the thickness of the pipe.
The pipe is one of eight pipes that is part of the station’s service water system that carries river water used to cool plant equipment.
Operators at Byron Generating Station returned Units 1 and 2 to
service on Wednesday, October 31.
The system is located on the non-nuclear side of the plant and not in
direct contact with any reactor components. While the plant was off line, workers replaced six of the eight pipes on the system that showed
similar signs of corrosion. Repairs to the two remaining pipes are in progress.
To replace the pipe, workers had to remove concrete around the pipe, cut out the portion of corroded pipe and install new
24-inch carbon-steel pipes. Workers also will apply a coating to the pipes as a preventive measure to reduce future corrosion.
“I appreciate the hard work of our employees and the number of local specialty vendors who assisted us. They worked together as a team to complete the tasks needed to return the units to service,” said
Dave Hoots, Byron site vice president.
With both units back in normal operation, residents will see the water vapor clouds coming out of
the two large cooling towers.
