Three Mile Island Unit 1 Returned to Service

Thousands of Equipment Upgrades and Maintenance Tasks Completed Safely, Additional Workers Bring Economic Boost to Region

LONDONDERRY TWP., PA (November 27, 2011) – Following a safe and successful refueling outage, station operators placed Three Mile Island Unit 1 back in service on Friday, Nov. 25 at 3:50 p.m. and the plant reached full power this afternoon. During the outage, workers replaced nearly a third of the reactor’s fuel and safely performed more than 17,000 inspections and maintenance activities on a variety of plant components and systems. This year, workers also upgraded the plant’s main electrical generator and installed a new digital control rod drive system.

“TMI’s refueling outage was a big success thanks to the dedication and talent of our full-time personnel and the many supplemental workers who supported us,” said Site Vice President, Glen Earl Chick. “We completed a host of maintenance activities and equipment upgrades that will help us run the plant safely and efficiently for many years to come.”

Three Mile Island used the talents and expertise of more than 1,700 supplemental workers to support this year’s refueling outage. Many of these workers traveled to Three Mile Island from outside the area, providing a significant boost to the local economy.

Three Mile Island Unit 1 generates 852 megawatts of carbon free power - enough electricity for about 800,000 homes. Electric customers were not affected by the plant being off line.
