Dec. 02--YORK, Pa. -- A nuclear-powered plant that produces enough electricity to continuously power 800,000 homes came back on line last month.

Three Mile Island returned to service on Nov. 26 and reached full power a couple of days later after workers completed a routine refueling and maintenance outage at the station.

The plant went off line last month.

More than 1,700 technical workers supplemented Exelon's personnel during the outage by replacing nearly a third of the reactor's fuel, performing inspections and upgrading to the plant.

Those improvements included replacing a large reactor coolant pump motor and overhauling turbines used to make electricity.

Additionally, TMI partnered with nuclear services vendor AREVA to install new control rod drive mechanisms safely and in record time.

Control rod drive mechanisms control the nuclear reaction inside the reactor.
