U.S. Nuclear Industry Tested by Twin Threats From Mother Nature www.sfgate.comby Panserbjorne9 8/24/2011 3:29:10 AM- "One of the plant's four diesel generators, which power the reactors' cooling systems during the blackout, stopped working as a result of a coolant leak, Roger Hannah, a spokesman for the U.S. Nuclear Regulatory Commission, said in an interview." I call bullshit on this. The NRC report from MAY showed a busted generator. They just never fixed it.by Panserbjorne9 8/24/2011 3:31:17 AM
@Panserbjorne9 Do you have a link to the report? Thxby Cryptococcus 8/24/2011 4:20:33 AM- "If Fukushima wasn't a wake-up call, this really needs to be to get the NRC and industry moving to do seismic reviews of all the nuclear power plants in the country." www.reuters.comby Cryptococcus 8/24/2011 4:21:45 AM

Dominion's North Anna Power Station Restores Offsite Power: dom.mediaroom.com
"Dominion Virginia Power's North Anna Power Station has restored off-site power, eliminating the need to rely on its back-up generators. The station remains in an Alert, the second lowest of the four emergency classifications of the U.S. Nuclear Regulatory Commission.
The station's two nuclear reactors shut down following an earthquake near the station that occurred at 1:51 p.m. EDT today. The reactors shut down automatically and no damage has been reported to systems required to maintain the station in a safe condition. Several aftershocks felt in the region that occurred later today did not affect the station.
As designed, four diesel generators supplied power to the station while the off-site power was unavailable. 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 the offsite power was restored. Repairs are complete to the diesel generator."by es 8/24/2011 9:13:40 AM

Tokyo Tower lit up with human-generated power [24 August, 2011]: www3.nhk.or.jp
"Thousands of people have pedaled bicycles to generate electricity to light up Tokyo Tower in an energy-saving campaign.
An event was held at the Japanese capital's landmark on Tuesday night.
Participants, including professional cyclists, took turns pedaling 10 power-generating bicycles in front of the tower.
Shortly after 8 PM, 9 lights illuminated the tower against the night sky, drawing cheers from the participants.
The night-time illumination of the tower has been shortened following the March nuclear accident in Fukushima, which caused power shortages."by es via Www3.nhk.or.jp 8/24/2011 9:25:49 AM

- About the french EPR... Of "gaps" and "weaknesses." That's what found by an inspection of the construction site of the Flamanville EPR reactor, the Nuclear Safety Authority (ASN), which has asked EDF to "make significant efforts to demonstrate the quality of construction ".In its edition of Wednesday, August 24, Le Canard Enchaîné reported an "explosive inspection." After "inspecting review", allowing a thorough review, conducted between March 1 and May 13, Jean-Luc Lachaume , the Director General of the ASN, refers to "findings of thirteen gap "in a letter addressed to the management of EDF.

@All Hi! The lightning man means it's weather time again....sorry!:-) Yes, I am not usually one to jump on something this far out but currently there is two systems in the north west pacific(ignore the third most northern system-not of great concern-check here for sat image- www.usno.navy.mil ) TS-14W is already consolidating and forming into an organized system and is currently in a strengthening pattern, the system labeled "high" has already had TCFA issued for it (check at JTWC), it is forecast to consolidate and strengthen also. Currently all models are in agreement of formation and growth of these two systems side by side, models also indicate at least one if not both systems affecting Japan but as the scenario continues to this may change and it is early days to be relying on weather models to predict anything too definite but with such widespread agreement between the models and the conditions in the area definitely able to sustain such a scenario it is a very freighting prospect indeed! It is actually a very rare event for two systems to do this, it is really an unknown thing if they begin to interact with each other and from my learning it has only ever been witnessed a very few times.....it is also a very dangerous situation as the steering and final location of the systems becomes very hard to predict should they begin to interact in such a manner. It is definitely something that needs watching over the next 120 hours, by that time a definite on what will happen should be obvious. Frankly I hope I and the models are completely wrong about this…..”Japan” and “worst case” are not two things I like to put in a sentence anymore but…well…. All I can say is I am no meteorologist! :-)
by Thunder via Usno.navy.mil 8/24/2011 10:06:07 AM- One thing that did come out of Chernobyl was the knowledge that the main source of radiation that people got was from the food- so why are they still putting cattle/ crops etc into the market translate.google.comby elainekirk 8/24/2011 10:06:27 AM
- Radiation limits to be tightened at schools [24 August, 2011]: www3.nhk.or.jp
"The Japanese government will tighten radiation exposure limits for children at schools in Fukushima Prefecture.
The education ministry says it will lower the threshold for ***ulative external radiation permitted at schools and kindergartens to a maximum annual exposure of one millisievert. The figure translates to less than one microsievert per hour.
The previous standards of a maximum 20 millisieverts per year and 3.8 microsieverts per hour were set in April following the accident at the Fukushima Daiichi nuclear power plant.
The ministry says the subsequent removal of topsoil from playgrounds has pushed radiation readings at all schools below the 3.8 benchmark.
It says it will not require schools to keep children indoors even if radiation levels exceed the new limits, but recommends that they be promptly decontaminated if they go outside.
The ministry is to inform Fukushima Prefecture of its decision to change standards on Friday."by es 8/24/2011 10:07:28 AM - hi @Thunder :)by es 8/24/2011 10:07:42 AM
- @Thunder 120hrs that is 5 days then and fuku is in no way in any state to deal with it :(by elainekirk 8/24/2011 10:07:58 AM
- @Panserbjorne9 thanks for looking for source of generator not being fixed. Good morning everyone. Catching up.by Cryptococcus 8/24/2011 10:15:39 AM
- translate but I will ask rockhopper to verify
tepco 4 days before the earthquake had actually submitted they seismic studies and they said the expected height of any tsunami in the area was 10 mtrs and not the 5.7 that tepco and nisa have been reporting translate.google.comby elainekirk 8/24/2011 10:17:13 AM - @es Hi! Hope you have been well! @Elaine(@All) lets just hope it's all wrong or they get off lucky like in the past, again winds shouldn't be too great, no 300km/h or anything but enough to stop work most likely, and in worst case perhaps a prolonged stoppage of watering the SFP's and cores, not to mention blowing crap everywhere and the slight possibility of further damage??? But of course the biggest problem as usual will be the rain should it happen. oh and they have about a week, should current forecasting hold the systems will begin to affect Japan starting next Tuesday/Wednesday, by the weekend or Monday at the latest we should have a good idea of what the situation will be.... HERE's HOPING for NOTHING!!!
On the quite....I am actually a little excited to see this should it come off, I just like cyclones, they don't need to hit Japan but can't help but wish it a little!:-(by Thunder 8/24/2011 10:20:56 AM - @Thunder ty :)by elainekirk 8/24/2011 10:34:58 AM
- @Elaine no problem, anytime!!! I love weather and weather is about all I have left to contribute anymore, the whole reactor/radiation thing is just such a mess...where to start??? In the end all their denials and ass covering will cost dearly I think, the problem is those who should pay for it the most won't be the ones most greatly affected.....it's a sucky world most days!by Thunder 8/24/2011 10:42:24 AM
- @Thunder yes it is that's for sureby elainekirk 8/24/2011 10:53:39 AM
- got confirmation on the news report translation from rockhopper
@ElaineKirk "TEPCO reported Nuke Safety Agency on March 7th that tsunami of 10m-high could hit Fukushima plants." TEPCO admitted. @ElaineKirk Until this third-party investigation, TEPCO kept saying that their highest estimation was 5.7m. But, they knew 10m could.by elainekirk 8/24/2011 11:07:18 AM - The group also found out that radiation from Fukushima will only decrease by one-tenth per year, which is about 100 times slower than radiation from the bomb. search.japantimes.co.jpby Cryptococcus 8/24/2011 11:25:22 AM

- One thing is for sure, Japan and the Japanese are going to become experts at radiation cleanupby Cryptococcus 8/24/2011 11:33:16 AM
- In May, the federal government simulated an earthquake so massive, it killed 100,000 Midwesterners instantly, and forced more than 7 million people out of their homes. At the time, National Level Exercise 11 went largely unnoticed; the scenario seemed too far-fetched — states like Illinois and Missouri are in the middle of a tectonic plate, not at the edge of one. A major quake happens there once every several generations. www.wired.comby Cryptococcus 8/24/2011 11:42:06 AM
- North Anna shut down because of the nuclear plant lost access to power.by Cryptococcus 8/24/2011 11:54:01 AM
- Jim Norvelle, director of media relations for Dominion Resources Inc., operator of the North Anna plant, said its workers inspected the switch yard, through which electricity enters and leaves the installation, and believe problems there caused the nuclear plant to lose access to grid power. When the plant lost access to grid power, it automatically shut down. online.wsj.comby Cryptococcus 8/24/2011 11:54:14 AM
Morning! (afternoon-evening)by lillymunster 8/24/2011 12:09:20 PM- Thank you Thunder and Oliver for the news, if your still here. :-) Going to run those as stories this morning. Let me know if anyone found anything else major overnight.by lillymunster 8/24/2011 12:15:24 PM
- @Cryptococcus Any word if they have offsite power back yet?by lillymunster 8/24/2011 12:15:43 PM
Good morning, the astounding aspect of the North Anna npp shutdown to me is that the reactor buildings themselves should be outfitted with seismic sensors that should trigger reactor scrams automatically in an event two notches away from design basis. That just did not happen.by Peter Melzer 8/24/2011 12:39:11 PM- @Peter Melzer do we know for sure if the seismic equipment for the plant was removed as reported?by lillymunster 8/24/2011 12:43:13 PM
- @lillymunster , the report states that sensors installed around the plant were removed. In addition, sensors should be built into the buildings like in Japan I believe. If not that would be a grave mistake with a plant near a fault.by Peter Melzer 8/24/2011 12:47:22 PM
- @lillymunster oh yes they got power back long ago I thinkby Cryptococcus 8/24/2011 12:55:14 PM
- This VEPCO report, from a seismic event in December 2003, suggests there was some seismic monitoring equipment at North Anna NPP back then which "was not actuated by the seismic activity". The same brief report also specifies that, "The plant alarm setpoint is set to actuate at 0.01g": pbadupws.nrc.govby es 8/24/2011 1:01:11 PM
