Central Va., East Coast recovering from 5.8 quake, Richmond Times Dispatch, August 23, 2011:
[...] Dominion spokesman Richard Zuercher [...] said North Anna’s operators were preparing to manually shut down the units after the quake when the power station’s operating system automatically powered down both units, which supply about 10 percent of the state’s electricity.
“Their staff is obviously looking at every inch of that plant,” the governor said. [...]
UPDATE: North Anna’s 2 nuclear reactors shut down after quake, Richmond Times-Dispatch, August 23, 2011:
Dominion Virginia Power shut down its two North Anna reactors as a result of the earthquake, according to the company.
“The earthquake was felt at the North Anna Power Station and the reactor operators, following procedures, shut down the reactors,” said company spokesman Jim Norvelle. “It was a manual shutdown.” [...]

…who knows with these nukers?

Anyone seen a video clip of North Anna?
Report Comment
I have. On fox news. Posted about it under a different topic. Saw steam or smoke, probably exhaust of some kind. But I don’t know. Wonder if anyone else saw it and had any ideas
Report Comment
sorry for crosspost but:
They said officially that they are venting steam and that there are no nuclear releases…
Anybody near there with a geiger counter?

I hope this link works. This is pretty much what was on fox. Seems odd that they have footage from the air. I’m not sure this is from today.

And now I remember his name from the video conference:
“We did lose on-site power, but all the diesel generators are up and running,” Dominion spokesman Richard Zuercher said 30 minutes after the quake. “Everything appears to be operating just fine.”
SP: Yep…except for the one dead generator you conveniently forgot to mention.

I really expect that all 4 run when needed. This is totally unacceptable.

Someone didn’t want us to know that their automatic system failed.

First time poster but found ene during the fuku crisis and have checked daily. My father works for the largest nuclear power plant owner and operator in the US. A lot of misinfo appears to come around during times of high tension. Hoping to shed some light on this situation after talking to my father. During normal operation a plant’s generators snyc to the power grid. After the quake struck plant operators decided for safetys sake to manually shut down the reactor. During manual shutdown, power fluctuation from the decreased generation of electricity caused a de-sync from the power grid causing an automatic shutdown of the reactor due to an operator error. This is not ideal but dominion will not claim operator error causing the buffeting (power flucuations). Remeber these people were victims of the quake ans stress was high. So they claim automatic shutdown after the quake. The buffeting is also more then likely responsible for the lose of off site power due to a failure at the transmission switch station.

Release of steam is also needed becuase power is not being generated yet the reactor is still red hot and producing steam and this is all normal procedures. Lets just hope off site power is restored in a timely manner and until that happens remaing diesel generators continue to operate. Along with the plant being in sound condition. So far we both suspect there is not any danger as long as the generators work and coolant is circulating. If they fail they have batteries for several hours. Sorry for such a long post and double posting.

Thank you for posting jdotg. Are neither of you worried about piping and other things that might have been damaged by the quake (which the operator admits was at the very edge of the design basis of 5.9-6.1). Does your father have any insider info about ft. Calhoun or Fukushima you could share with us? I would very much like to know what people in the industry like your father are really thinking -privately- as we suddenly find nuclear peril and danger looming on all sides. Has he lost faith in the nuclear industry at all? Does he think that Northern Japan will be uninhabitable in the near future? Does he think nuclear power is worth the almost unquantifiable risks involved? Does he not think a nuclear disaster like fukushima is inevitable in the US if nuclear power plants continue to operate here?

Plant is relatively new in terms of others across the nation. But yes quake damage is concerning but no reports of leakage yet. Maybe they wouldnt tell us if it was. Praying it lived up to the safety standards.
Mum on ft calhoun but says exelon employees are in fuku.neither US plants are owned by exelon so hard to say. He hasnt discredited the nuke industry but would you bite the hand that feeds? He hasnt said much other about japan other than when it blew saying they have big problems. Hes a man of few words. But feels that although US plants are aging they are still safe through there design. Feels ultimately fuku will have little impact on actual regulations.

I read somewhere that nuclear power stations were only designed to run safely for 20 years. This energy is exorbitantly expensive and no insurance company will touch them. Please stop fascistic nuclear power.

Please stop the government handouts to the nuclear industry. No more welfare for the nuclear industry.

Energy doesn’t need subsidy, it needs to freely compete in a true market. There are subsidies for all kinds of power: oil & gas, coal, solar, wind, etc. but the biggest is nuclear. As Gunderson pointed out, the insurable premise behind coverage for reactors is that any meltdown could never become a melt-through. Ooops three times over. If you demanded any company wanting to build a nuclear power plant be responsible for even 2% of damages from any accident, there would never be a private reactor built again. Get rid of all energy subsidies together, not just nuclear – level the playing field, that will gain the support of non-nuclear energy sources.

Hi radegan, in general, I agree with you, but I think the “insurance point” is even more important.
A Swiss institute (prognos) has calculated way back in the 90′s that IF a nuke plant had to be insured against the damage it can cause, the price for energy per Kw/h would be 20 times higher than what we pay today.
The sheeple just don’t get that the real price tag for nuke electricity is not on the electricity bill, but on their tax slip.

ALERT DECLARED DUE TO AN EARTHQUAKE IN THE AREA AND A LOSS OF OFFSITE POWER
At 1403 hrs. EDT, North Anna Power Station declared an Alert due to significant seismic activity onsite. The Alert was declared under EAL HA6.1. Both units experienced automatic reactor trips from 100 % power and are currently stable in Mode 3. All offsite electrical power to the site was lost. All four emergency diesel generators (EDG) automatically started and loaded and provided power to the emergency buses.
While operating, the 2H EDG developed a coolant leak and was shutdown. As a result, the licensee added EAL SA1.1 to their declaration.
All control rods inserted into the core. Decay heat is being removed via the steam dumps to atmosphere. No personnel injuries were reported.
!!all 4 ???!! Which is it???? This is the report sent to the nrc!

I would think that a failure or a back up generaor would be a leading news story. Why would we need to find it what happebed the next day from the nrc report.
