Perry Nuke Coasts Down to Refuel;Posts 98.2 Percent Capacity Factor

LCG, Feb. 16, 2001First Energy Corp.'s Perry nuclear power plant was reported at 87 percent of capacity this morning in the Nuclear Regulatory Commission daily plant status report. The reactor is coasting down to a refueling outage after running for 655 days at a capacity factor of 98.2 percent.

Perry was on-line for all but 11 of those 644 days and during the period ran off its longest continuous run a stretch of 399 days.

During the refueling outage, workers will replace a turbine rotor, which will be the final step in boosting the plant's output from 1,250 megawatts to 1,320 megawatts. About 1,000 workers will also attend to replacing more than a third of the reactor's fuel assemblies and performing other maintenance and repair operations that require a cold plant.

"Our work schedule is ambitious, but I am confident our employees will meet the challenge," saidJohn Wood, site vice president at Perry. "We expect to complete some 7,500 maintenance activities during the refueling to help continue strong operations until our next refueling in 2003."
