Dominion’s North Anna Power Station Restores Offsite Power

RICHMOND, Va., Aug. 23, 2011 /PRNewswire/ — Dominion Virginia Power’s North Anna Power Station has restored off-site power, eliminating the need to rely on its back-up generators. The station remains in an Alert, the second lowest of the four emergency classifications of the U.S. Nuclear Regulatory Commission.

The station’s two nuclear reactors shut down following an earthquake near the station that occurred at 1:51 p.m. EDT today. The reactors shut down automatically and no damage has been reported to systems required to maintain the station in a safe condition. Several aftershocks felt in the region that occurred later today did not affect the station.

As designed, four diesel generators supplied power to the station while the off-site power was unavailable. One of the four generators was taken off-line to repair a generator coolant leak, but a fifth generator at the station was activated to replace it until the offsite power was restored. Repairs are complete to the diesel generator.

The company also inspected the Lake Anna Dam after the earthquake and determined it sustained no damage. Station inspections are continuing to assure no damage has resulted from the seismic event.

No release of radioactive material has occurred beyond those minor releases associated with normal station operations.

The earthquake was felt at the company’s other nuclear power station, Surry Power Station in southeast Virginia, but not as strongly. Both units at Surry continue to operate safely. Surry has exited a Notification of Unusual Event (NOUE) it declared earlier today, the least serious of four NRC emergency classifications.

U.S. nuclear power stations, including Dominion’s four stations, were built to seismic standards for their regions.

Dominion Virginia Power is a subsidiary of Dominion (NYSE: D). Headquartered in Richmond, Va., Dominion is one of the nation’s largest producers of energy. For more information about Dominion, visit the company’s Web site at www.dom.com.

Epicenter was located approximately 4 miles south-southeast of Louisa, VA; 4 miles southwest of Mineral, VA; 41 miles northwest of Richmond, VA; and 83 miles southwest of Washington, DC. Depth of earthquake is report at approximately .6 mile.

FEMA has approved federal disaster assistance for individuals, renters and business owners in Louisa County who experienced damage as a result of a 5.8-magnitude earthquake that struck Virginia on Aug. 23 and caused more than 40 aftershocks. The governor appealed FEMA’s initial decision to deny federal disaster aid to Louisa County.

Since the original request was made Sept. 20, officials have found more extensive damage than what was originally reported in more than 1,400 homes. Some damage that was first categorized as minor has become worse as a result of more than 40 aftershocks. The appeal included a letter from Virginia’s entire congressional delegation supporting the request.

Individuals and families in need of earthquake recovery aid can register immediately by calling 1-800-621-FEMA (3362) or 1-800-462-7585 (TTY) Monday –Friday from 6 a.m. – midnight Central time, 7 a.m. – 1 a.m. Eastern time, and Saturday and Sunday from 7 a.m. – 10 p.m. Eastern time.
