Nuclear power plant enters refueling outage

Exelon Corp. (NYSE: EXC) said more than 2,000 supplemental workers are at the 2,345 MW Limerick Generating Station near Pottstown, Pa., to support the plant’s 2012 refueling outage.  Exelon Nuclear employees and supplemental workers will perform over 13,000 outage-related activities, including equipment upgrades, safety inspections and plant improvements.

Major work to be performed includes the replacement of service water piping systems, an integral part of the plant’s cooling systems; installation of new automatic speed drives that supply power to vital systems; and a number of electrical upgrades. Exelon said these activities cannot be performed while Unit 1 is online.

Limerick Unit 2 will continue to generate electricity during the Unit 1 outage.

Units 1 and 2 received their operating licenses from the U.S. Nuclear Regulatory Commission (NRC) in 1984 and 1989.
