Offsite power restored to Dominion’s North Anna Power Station
- August 24, 2011
Dominion Virginia Power’s North Anna Power Station has restored off-site power, eliminating the need to rely on back-up generators. Following a 5.8 earthquake Tuesday, the station remains in an “alert” status, the second lowest of the four emergency classifications of the U.S. Nuclear Regulatory Commission.
The company said in a release that power was restored Tuesday night. The station’s two nuclear reactors shut down after the quake, which occurred shortly before 2 p.m. The epicenter was near Mineral, a small town just a few miles from the power station. The release said reactors shut down automatically, and there was no damage to the plant’s safety systems. Several aftershocks felt in the region last night did not affect the station. Its four diesel generators supplied power while off-site power was unavailable. Dominion Virginia Power said 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 offsite power was restored. At this time, repairs are complete to the diesel generator. The company did not say when the plant’s two nuclear reactors would be restarted.
It inspected the Lake Anna Dam after the earthquake and found no damage. Dominion Virginia Power is a subsidiary of Dominion. With a Richmond headquarters, Dominion is one of the nation’s largest producers of energy.
