The North Anna nuclear power plant, which had to be shut down following the August 23 earthquake that struck the D.C. region, is reported to have leaked as many as 272 gallons of cooling water into a nearby lake, according to a report released by the Nuclear Regulatory Commission.
The leak was reportedly caused by a faulty motor operated valve in the system's cooling tower, which prompted a report to the Virginia Department of Environmental Quality when it was detected on October 14.
The spilled water does not post a danger to the public's health, according to the NRC report.
"Samples of the bearing cooling water were analyzed by Chemistry," says the report. "All chemical parameters analyzed were within VPDES (Virginia Pollutant Discharge Elimination System) limits."
The North Anna plant, which is operated by Dominion, has been under scrutiny from the NRC after it was automatically taken offline following the 5.8-magnitude earthquake, which is believed to have shaken the plant more strongly than it is licensed to withstand. The NRC just recently concured with Dominion's claims that the plant suffered no damage.
