Nov. 26, 2002 — FirstEnergy Nuclear Operating Company (FENOC) announced that Beaver Valley Power Station Unit 1 returned to service following scheduled maintenance work designed to improve plant performance and reliability. The unit, one of two at the plant, was taken off-line late Monday, November 11, 2002.

The unit began producing electricity early Saturday morning. Currently, it is operating at 93% and is expected to achieve full power later this week.

During the outage, maintenance was performed on more than 20 plant systems, including the steam supply and cooling water systems. Other maintenance activities included replacing numerous valves and cleaning and inspecting the reactor head and vessel.

The inspections found no signs of leakage from the control rod drive mechanisms or the incore tubes at the bottom of the vessel. The reactor head also was washed and reinspected to confirm its safe condition. In accordance with NRC regulations, the reactor head will be inspected again during the unit’s next refueling in the first quarter of 2003.

Beaver Valley is owned by Akron-based FirstEnergy Corp. (NYSE: FE – News), and operated by its subsidiary FENOC. FirstEnergy is a registered public utility holding company.
