Japan Earthquake

Japan Earthquake | Page 1069

@RBeaner I don't know enough (or care enough) to argue which went first, and why. I don't do liability for TEPCO, so whether a crappy design failed at the EQ stage or the tsunami stage is irrelevant to me. Best I can tell, it failed everywhere at the same time because the planners (in that brash arrogance we humans are known for), went with the cheaper hundred-year tsunami records rather than the expensive and extraordinary historic records.

@radioguy I don't either. It did stand up to design parameters, which, of course, wasn't good enough.

"Oh yes, there was that, but in 600 years we've never seen it again, so that must have been a once-in-a-planet occurance."
by radioguy 5/9/2011 8:38:48 PM

@Edano Ouch. There it is, and it could have been worse, but that's terrible placement.
by radioguy 5/9/2011 8:40:34 PM

@radioguy I raed somewhere through this today that the likelyhood of a quake greater than 8 in 100 years was estimated to be 10%, and they thought that was great. 10% is a lot. So they went liberal and designed it for 8.2-8.4.

www.technologyreview.com Do you think the solid blue line fits the plots? Shouldn't the slope be greater? www.technologyreview.com

@Jim i am confused now (not hard).... yesterday or the day before i thought we were certain that the reactors 1-4 were on bedrock.... was that incorrect or is it a termenolgy/transltion problem as to bedrock vs what we are looking at now???
by fitter 5/9/2011 8:55:32 PM

@Jim Funny how bad 10% looks as odds when you really think about the consequences.
by radioguy 5/9/2011 8:55:46 PM

@Jim Yes, but the blue dots are measurements from seawater.

@dean not sure I think so...Just looked tbs cam first time in hrs and #4 looks terrible
by elainekirk 5/9/2011 9:07:08 PM

well...I have some research into the intial events after the earthquake and want to finish putting together the information, along with emergency action procedures and plant recovery procedures for recover from a scram, going to cold shutdown from a scram, actions in the event of the seismic trips, and then some observations on the whole mess. This will include what was lost at the EQ, best identifed systems that were lost or did not function due to the loss of power from the EQ, then the actions from the TSUNAMI..
by dean 5/9/2011 9:11:05 PM

nancy was working on this as of this morning. we want to have the best idea for the first hours as we can, specifically what happened in the plant from the seismic scram until the tsunami and the resultant fuel melt etc.
by dean 5/9/2011 9:13:10 PM

@fitter There is differing info on that, What is Bedrock? is Indurated Shale at 17 meter depth bedrock, or is it granite strato at 46 meters depth. mdn.mainichi.jp or is it at 17meter www.iitk.ac.in
by RBeaner 5/9/2011 9:14:33 PM

Can someone post a link for the 'TBS cam'? I've heard it mentioned frequently, never seen a link (looked in the sticky area and the fukishimafaq page, couldn't find it.

@you I saw you'rs.tryin to pull one over @me huh ? ))
I did I was sure I would beat you there but oh no super speedy veen oui got there first

Gotgo but, still looking for a tabnle I saw before, include radioactivity samples, 1 centimeter rediatio0n readings an 1 meter (or some 36 cm) radiation readings at the same point, I think from TEPCO, but not their normal info release.

@dean That seems to be the huge data gap, that hour between EQ and Tsunami. I am going to dig into TEPCO and some of the agency documents a bit more tomorrow. Also going to see if CNIC has data, they seem to know more than the media regarding those first hour and hours.
by Nancy 5/9/2011 9:28:38 PM

RBeaner the first source listed about the bed rock was from a quote made by Nan and I don't think he's demonstrated any credibility to know anything about reactors not to mention bedrock,, the second source was on a paper which was considering the #6 plant and I didn't see bedrock mentioned

tippycam is massively hazey today. www.youtube.com
by Nancy 5/9/2011 9:29:33 PM

fantastic Nancy,, I'd like to work with you and feed you the information I have as well,,, and I must say that I'm going to try to look at the input made by RBeaner who has had some good points... I want us to all be in agreement the best we can

Small amount of radioactive gas leaks from Tsuruga nuke plant

FUKUI, Japan, May 9, Kyodo

A small amount of radioactive gas leaked from a nuclear power plant in Tsuruga, Fukui Prefecture, but there is no impact on the surrounding environment, the plant's operator Japan Atomic Power Co. said Monday. english.kyodonews.jp

this is the plant where water was spilled last week. maybe we have to keep an eye on that plant.
by Edano 5/9/2011 9:32:22 PM

@dean sounds like a plan. I have a rough working outline, mainly just so I can keep links and such arranged in a logical manner. When you have things on your end ready let me know, I will want to run anything I have found by you and the group to make sure I have things right that I found. Hope to get some more data tomorrow.. here's the outline I am working with. docs.google.com
by Nancy 5/9/2011 9:33:29 PM

@dean can you also post your raw data here so we can also look at it, while nancy is putting hers tother
by fitter 5/9/2011 9:34:10 PM

@? I was starting dinner. 46-47m to consolidated igneous rock.
by Jim 5/9/2011 9:36:04 PM

'Bedrock' is not a geological term, it is a builders term.
by Jim 5/9/2011 9:36:45 PM

@Jim well that sums it up in a heartbeat.... I am a builder,what is the correct term?
by fitter 5/9/2011 9:40:39 PM

looks good nancy I will add to that and insert some things that I find and will put my stuff in red ok?

I have been out all day so you may have seen this video of workers inside unit 1 - what the hell is the green slime on the floors ???????

by elainekirk 5/9/2011 9:41:59 PM

@fitter We use a descriptive term that tells what it is. I.e. a basic basaltic intrusion or whatever.
by Jim 5/9/2011 9:42:53 PM

jim is definitely right on the bedrock comment.... what they build on is more from a construction term,,,, bedrock
by dean 5/9/2011 9:44:10 PM

@dean The first source was a quote from Kan saying bedrock was 46 meters below ground, talking about tanking cintaninated water. The second quote never uses the word bedrock, it says the plant is sitting on "mudstone"....Read'er
by RBeaner 5/9/2011 9:44:19 PM

@fitter Actually geologist do use that term, but it's informal.
by Jim 5/9/2011 9:44:20 PM

I never know what's been passed along, and these came up in a search: www.technologyreview.com <== Chain Reactions Reignited At Fukushima After Tsunami

which cites this: arxiv.org <== Deciphering the measured ratios of Iodine-131 to Cesium-137 at the Fukushima reactors
