Fukushima Daiichi Area Off-limits for Fall Fish Favorite
The eagerly awaited season for Pacific saury, the fish known as sanma here, has just begun.
But this year fishermen will have to hunt a little farther and wider than usual to catch the slender, silvery staple of Japanese cooking. And customers may have to pay more.
That’s because a cooperative representing the country’s saury fishing industry said this week that it will not catch any sanma in waters within a 100-kilometer (62-mile) radius of the stricken Fukushima Daiichi nuclear plant, a move to address concerns among wholesalers, retailers and consumers about possible radioactive contamination of seafood in the area. With trace amounts of radioactive cesium already detected in some Hokkaido samples in early July, at levels far below the Japanese government’s regulatory limit, the precaution seems sound.

Japan's nuclear regulator says the operator of the Fukushima Daiichi nuclear plant predicted an over 10-meter-high tsunami in 2008, but failed to report its prediction to the government until just before the March 11th disaster.
A spokesperson for the government's Nuclear and Industrial Safety Agency told reporters on Wednesday that the Tokyo Electric Power Company, or TEPCO, reported the prediction to the agency on March 7th.
TEPCO says it made the estimation in 2008 when calculating the maximum tsunami height in the event of a very powerful earthquake near the plant.
The maximum possible wave height originally assumed by TEPCO when it designed the plant was 5.7 meters.
The agency says it ordered the company to submit a detailed report as quickly as it could and suggested the need to reform the facilities when the company provided the prediction.
The agency's official in charge of nuclear disasters, Yoshinori Moriyama, says it takes seriously its failure to fully predict the possibility of a major tsunami before the disaster.
TEPCO says it didn't mean to disclose the assessment since it was a tentative calculation for research purposes based on a simulation.

@RadioGuy , back, true.It happens all the time in PR releases.by Peter Melzer 8/24/2011 5:37:14 PM- @Dean:
Tokyo Tower lit up with human-generated power
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.

- Eye-opening blog of Fukushima robot operator taken offline
Tokyo Electric Power Co. (TEPCO), which owns the Fukushima plant, is attempting to get things back to normal by using military robots provided by U.S. company iRobot. Due to the lack of communications in the area of the plant, these robots are being operated by individuals who are put in danger every day close by the reactors as they go about their clean-up tasks.
One of those operators decided to write a blog talking about his work, and it has proved very telling and informative about both the conditions at the plant and the robots themselves.
Working conditions are less than perfect. Long hours, ignored warnings, and the link to the robots during crucial clean-up work being put in jeopardy due to stupid decisions are all touched upon. We also get to learn about the limitations and advantages of each robot in this rather unique situation.
The identity of the blogger is unknown as he/she signed off simply as S.H. There is hope that the blog posts will return at some point in the future, or that the operator will come forward once his work is done to present his findings and help robot designers make better robots for these situations.

Just as an aside, Dominion's initial press release yesterday mentioned that "The earthquake also caused the company's newest power station, Bear Garden in Buckingham County, to shut down automatically.": dom.mediaroom.com
It's not clear whether this shutdown was triggered by seismic monitoring equipment or something else, but Bear Garden was officially opened just last week and is circa 60 miles SW of North Anna NPP, burns natural gas and, according to this report is "literally the most powerful new employer and biggest taxpayer in Buckingham County": www2.dailyprogress.com

@Peter Melzer yep. We've got the technology and more coming. embedded piezoelectric sensors in concrete for example
by Cryptococcus 8/24/2011 5:56:08 PM
@peter hello! did you feel MOVED yesterday? The office had a seismic event, not one I care to repeat! On the articles floating around about the removal of "seismic monitors" do you happen to know if they were "monitors" that belonged to DP (domion power) or were they an outside source? The only detailed one I have seen seemed to infer that they were the property of a "college" or "reshearch" facility... in which case would/should not effect plant safety systems (may have been Virginia Tech, from the acromon) Do you have any other sources or links.... ?????? thanks fitterby FITTER 8/24/2011 5:56:43 PM
Very odd, Bear Garden is cited as being seismic tripped but it is a natural gas power station, not a nuke plant as the media was framing it yesterday. www.power-eng.comby lillymunster 8/24/2011 5:57:17 PM- What the east coast earthquake means for US nuclear plants

- @Peter @lillymunster okay these are called seismic trip (scram) systemsby Cryptococcus 8/24/2011 6:13:44 PM
Hi @all I have been out have you seen this I posted a news report this morning
TEPCO reported to NISA that the possibility of 15m class tsunami may hit Fuku nuke plant 4 days before 311 cont
but NISA instructed TEPCO to remain silence, as it's not worth reporting. Fuku chief facility mgr Matsumoto cont
explained that it was still research level result and didn't think we have to inform public. NISA Moriyama cont
Nuclear emergency preparedness offc provided this to accident investigation/test committee to validate the issueby elainekirk 8/24/2011 6:13:50 PM- @FITTER , hello, we were moved three times, once around 1:00, then around dinnertime and lastly shortly after midnight. But there is no visible damage here. Schools are open. Nothing like the pictures from D.C. This only goes to show that seismic waves do not travel evenly. In fact, I came across a research study on the Haiti quake last year which found a rocky ridge near Port-au-Prince where the nature of the rock had amplified the waves. The opposite may also be possible.
To North Anna, someone posted this report www.rawstory.com last night which I read the way that sensors outside the premises were removed as you say. At Fukushima sensors are installed at all strategic locations in the reactor buildings, and I assumed that would be the same in the States. Otherwise an automated seismic scram is impossible. However, in the CNN interview I posted last night the utility spokesman was saying that the operators were about to shutdown the reactors, when the reactors were tripped by the power outage. That meant to me that there was no automatic seismic trip, and the operators in the control room shut down the reactors manually after they got shaken.by Peter Melzer 8/24/2011 6:13:55 PM - @elainekirk Do you have a link for that? The Japanese lang. source I found off twitter said 10m but was a pretty garbled translation.by lillymunster 8/24/2011 6:18:09 PM

@lillymunster Japan utility knew of tsunami threat: government
www.lakewyliepilot.comby Panserbjorne9 8/24/2011 6:20:42 PM- @Peter Melzer that was the basis I took it under also, the media is reporting no seismic scram. That is why I contacted Dominion's PR dept to give them an opportunity to set the record straight if they think these media account are incorrect. So far no response.by lillymunster 8/24/2011 6:20:43 PM
- Ah, here's a company that sells these systems. Now just have to find the ones used in Bear Garden. Is there a way to access architectural drawings on Bear Garden? See the download "Seismic Early Warning System for a Nuclear Power Plant" www.seismicsystems.netby Cryptococcus 8/24/2011 6:21:36 PM
- Japan nuclear operator warned plant not tsunami-ready
The Nuclear and Industrial Safety Agency said the operator informed it just four days before Japan's massive March 11 earthquake and tsunami that waves exceeding 10 metres could hit the Fukushima Dai-ichi nuclear plant.
www.cbc.caby Panserbjorne9 8/24/2011 6:21:46 PM - @Peter Melzer thanks for the link... it links to a more detailed article that seems to confirm the monitors removed were a reshearch project of VT and not any that would be associated with Domion Power... It would make sence that VT would remove monitors due to "budget constrantes". I would image the NPP's monitors, would be a seperate system... I really don't know if I felt the aftershock, we were still trying to get it together from the shock of the actual EQ... You might say the "plates" shifted under our carpet!!! we now have an elevation difference in were the concrete sections meet! Glad you are all well!by FITTER 8/24/2011 6:32:40 PM
- @all I think Virginia Tech has a dept that follows the EQ's, We got our first readings yesterday from the student/parent alert system... the way it read it seemed as though they have a program that is doing research or monitoring on EQ's.. anyone should be able to acess public info from thier school web site...by FITTER 8/24/2011 6:32:57 PM
- @FITTER , take good care over the weekend. Irene may bring tons of rain and lengthy power outages to our area to say the least.by Peter Melzer 8/24/2011 6:35:43 PM

Today's morning rain was fairly radioactive with a count of 10500cpm. The hot spot tested slightly over 1000cpm indicating radioactive rain in the 10000cpm / sq meter range.
I tested panel 1 which is always much cleaner than the other solar panels and I was puzzled to see it testing in the 2000-2500 range. This is low since the hot spot was over 1000cpm. There is a direct correlation between the hot spot where the rain drips off the roof and what the solar panels collect.by Majj 8/24/2011 6:44:30 PM- @Peter Melzer We were already getting the generators ready, no one was figureing on the EQ.. but they use the schools and public buildings as evacuation centers during the hurricance .... but some are now closed due to damage or needing inspected.... Good thing Irene seems to be hooking to the right, so winds will be less... I have road out about six or seven here, but after the last one I am not so sure I would stay if the land fall was above the Outer banks... We are looking forward to the rain.. we have had a lot of days were the smoke from the dismal swamp gets so bad you can not be outside... the rain will be a big help there!by FITTER 8/24/2011 6:45:36 PM
- FYI on N Anna. Both Old Dominion and NRC were reporting that plant staff was doing a manual shutdown then the loss of offsite power caused the automatic scram. If they do have internal seismic equipment still it failed to scram the reactor.by lillymunster 8/24/2011 6:46:56 PM

@ElaineKirk "TEPCO reported Nuke Safety Agency on March 7th that tsunami of 10m-high could hit Fukushima plants." TEPCO admitted.by elainekirk 8/24/2011 6:58:43 PM - @lillymunster @peter Do you know what are the seismic paramaters for SCRAMing the reactors are? It could make sence to have a seismic event and not want the reactors to SCRAM automaticly, if there is no failure in the systems... they might want to do a manual "may be more controled and safer" shutdown.. would really have to know more about the systems.... 5.8 would be very close to any design factor for this area I would think.by FITTER 8/24/2011 6:59:53 PM
- @FITTER Yes they said 5.9-6.1 and I saw that acceleration factor in some document I read below. Maybe the NRC evaluation.by RadioGuy 8/24/2011 7:03:48 PM

- Plant seismic scram set point was .01g. In 2003 a 4.2 quake (.02g)
The Operating Basis Earthquake for North Anna is 0.06 g (5.4 on
the Richter Scale) and the Design Basis Earthquake for North Anna is 0.12 g (5.9 on the Richter Scale). The plant alarm
setpoint is set to actuate at 0.01 g.
pbadupws.nrc.gov
According to this if operating basis is the scram point it should have tripped and did not back in 2003. The scram should be set below the design basis.
