A loose bull isn't a problem until it gores one of your cows.

And yes, they worked as advertised...this time.

Apparent tornado causes Surry nuclear reactors to shut down

RICHMOND, Va. --

An apparent tornado touched down at Dominion Virginia Power's Surry Power Station Saturday, cutting power and causing the two nuclear reactors to shut down, the utility said in a release early this morning.

"Both reactors at the station shut down automatically as designed and back-up diesel generators started immediately to provide electricity necessary to maintain both units in a safe and stable condition, Richmond-based energy company said in the statement.

The apparent tornado touched down in the station's switchyard and access road. The utility said an off-site power source has been restored to both units.

"No release of radioactive material has occurred beyond those minor releases associated with normal station operations," Virginia Power said. "These minor releases are below federally approved operating limits, and pose no threat to station workers or the public,

The apparent tornado did not strike the two nuclear units, which are designed to withstand natural events such as tornados, hurricanes and earthquakes," the utility said.

No injuries were reported at the station and crews were working to restore full electrical service to the station.

Dominion reported the incident to the U.S. Nuclear Regulatory Commission and state and local officials.

Surry Power Station is located on the James River across from Jamestown.

U.S. Nuclear Power Output Hits Lowest in 4 Years After Tornado

U.S. nuclear-power output fell to the lowest level in almost 4 ˝ years after a tornado forced Surry Units 1 and 2 in Virginia to shut yesterday, the Nuclear Regulatory Commission said.

Power generation nationwide fell 3,730 megawatts, or 4.9 percent, from April 15 to 72,425 megawatts, or 71 percent of capacity, the smallest amount since Oct. 22, 2006, according to an NRC report today and data compiled by Bloomberg. Twenty-nine of the nation’s 104 reactors were offline.

The Surry reactors, operated by Dominion Resources Inc. with a capacity of 799 megawatts each, automatically shut down when a tornado touched down in the switchyard and knocked out offsite power, the NRC said. The incident was declared an “unusual event,” the lowest of four categories in the federal agency’s emergency classification system. Unit 1 was operating at full power and Unit 2 at 98 percent of capacity on April 15. .......

The reactors are good to go.  Sundowner, settle down dude.  Maybe Simaril can get ya some Xanax.

Zomg close call, shut down all nuclear power and go solar.

you killed the last surveyor we sent up the mountain in a jeep looking for the best place to put solar panels.

Isn't it kind of ironic that a nuclear powered electrical generator, needs outside power in order to function to generate electricity......
 :huh

Wait, so now you decide to not feed your over-sensationalism and to not over-react because things are under control and working as intended?   :rofl  :lol

Thank you for making my day.

OK. Who would like to explain to me how an electrical power plant loses electrical power while in normal operation?  :confused:

Some need power from an external source to run the backup systems.  There are some that are built on lakes that provide hydro power from the dam to run the backup systems.

I understand for back up.  What I don;t get is how can a plant that produces electricity lose power while its reactors are in operation.   Are they shutting them down and hope the backups kick in?  Sounds more dangerous than letting them continue normal operation.  At list we know that is working  :lol

Reminds me of that movie I saw once, tornado hit a nuclear reactor and it went hay wire and almost had a melt down. It was pretty funny cause it was so cheesy.

On my last drive to the store I wasn't hauling plutonium or uranium.  :aok

If I didn't make it back few, if any, would be affected.

Risk= Probability X Consequence.
It's a math thing.

Lot's of risk assessment web pages available.  :D
