* North Anna reactors shut after earthquake in August
* NRC must grant permission before North Anna returns
Oct 21 Virginia based power company Dominion said Friday it was ready to restart the 1,806-megawatt
North Anna nuclear power plant as soon as federal nuclear
regulators grant permission.
The U.S. Nuclear Regulatory Commission (NRC) is holding a
meeting at its headquarters in Rockville, Maryland, on Friday

The NRC has so far been unwilling to allow the two North
Anna reactors to restart without a thorough investigation so
soon after the Fukushima nuclear disaster in Japan.
In March, an earthquake and tsunami damaged the Fukushima
Daiichi nuclear power plant, causing reactor fuel meltdowns and
Dominion said both North Anna units are ready to restart
once the agency completes its independent review, analysis, and
on-site inspections and grants permission.
"The lack of damage from the Aug. 23 earthquake clearly
demonstrated that North Anna's true seismic capability is
greater than design basis of the station," David Heacock,
president and chief nuclear officer of Dominion, said in a
"While the quake lasted about 25 seconds, only 3.1 seconds
of intense motion occurred. The station could have withstood
significantly more," Heacock said.
At the NRC's request, Dominion said it agreed to perform
additional seismic analysis on certain components after restart
to quantify and further demonstrate they can meet specific
