@fitter It will just speed up the rate that the hydrogen and oxygen are diluted down.. Seems to imply they are in a hurry.

@Radioguy, that Arkansas was a 2.1, but only .1 km deep (that's scary, Japan just had a 4.9 one. What's interesting is the Arkansas quakes are all only within 5 miles of each other, if you look at the satellite, they are in the middle of some guys farm !!!! He must be really wondering if all heck is breaking loose, most of them are shallow
by wtm 4/10/2011 12:35:16 AM

@NHK Listener wonder if they are worried about yesterdays or the day before shake up having done something??? I really think they are just holding on by a thread..... that crew you were talking about last night thats on stand by (biol guys) that isn't cheap to just have there waiting, unless they thought that they were needed, granted we have a lot of our own military there to protect .....

Another Japan 4.8 this time.

Chemistry is not my forte but this could help understand the nitrogen maybe docs.google.com

@NHK Listener doesn't sound like they are building what i would call a coffer dam,with that sheet piling.... it would overflow, but the slit fence i don't think is going to stop much.... do you get the impresion that they are blocking the intake !100% or is it two completely different operations
by fitter 4/10/2011 12:43:12 AM

@Markfm - you may do this already, but check out the Japanese-only listings.
www.meti.go.jp
The current press releases are in the low 80's (e.g., 82, 83). For example, click on the line with (83). It will lead you to

Then look for the PDF attachment with about 374KB.

@elainekirk ok now that made my head hurt!!!!!! but ty it will make for good reading but that i need to print
by fitter 4/10/2011 12:44:59 AM

@fitter There are always a lot of tiny quakes in California and Japan. The constant barrage of them is high, and it's no stretch to attribute extra activity to plate movement. We know we've been seeing a lot of it, particularly on the Western edge in Japan. I'm happy to see all the little relief quakes here, but it doesn't seem to be balancing out. I don't know if that's unusual given plate dynamics or not.

@fitter Sheet pile dam around the intake and silt screen on the inlet opening.
by NHK Listener 4/10/2011 12:46:03 AM

@elainekirk We think alike LOL. I went looking,too, and came up with oxygen is heavier than nitrogen and hydrogen. Air doesn't separate, usually, but maybe they're worried about a layer of oxygen forming near the floor? Idk...
by marie rich 4/10/2011 12:47:38 AM

@LM So that answers where they were going to move the water.. Thanks
by NHK Listener 4/10/2011 12:48:03 AM

@NHK Listener The silt screen seems to be a cosmetic joke for the press' cameras.
by Reed 4/10/2011 12:49:24 AM

@NHK did you or @thunder have any luck with Sr-90 "hunting? @All did @nancy compile data readings of radionuclide findings?
by Isotope 4/10/2011 12:50:52 AM

@marie I think so too they are increasing purity from 98% to 99.8% that oxygen must be critical
by elainekirk 4/10/2011 12:51:03 AM

@Reed I think it is just a large filter for particulate matter and to keep fish out.. Pretty sure it wasn't a tepco idea.. Nisa I think
by NHK Listener 4/10/2011 12:53:23 AM

@LM Is that the same facility as this? 31Mar. tepco release On March 28th, a puddle of water was found at a centralized environmental
facility process main building. As a result of a radioactivity analysis,
on March 29th, we detected approximately 1.2 x 10Bq/cm3 in a full dose at
a radiation controlled area and 2.2 x 10Bq/cm3 in a full dose at a
non-controlled area.

Just watching it spread :( .... english.kyodonews.jp

I tried to work that nitrogen issue out too. I understand adding it as an inert gas to dull the hydrox flammability, and other than ammonia, I can't think what else it might make, but if you think about it, nitrogen makes some pretty explosive products. TNT and nitroglycerin come to mind, but there are others, like ammonium nitrate, NH4NO3. Note the ingredients: N, O, H. Period.

From wiki: "Ammonium nitrate decomposes into gases including oxygen when heated (non-explosive reaction); however, ammonium nitrate can be induced to decompose explosively by detonation. Large stockpiles of the material can be a major fire risk due to their supporting oxidation, and may also detonate, as happened in the Texas City disaster of 1947, which led to major changes in the regulations for storage and handling."

@NHK thanks, I am now thinking "conspiracy"? Which I hate to do!
by Isotope 4/10/2011 1:01:05 AM

@Dennis Tucker Jr Hi Dennis. I know that you were watching the trees and may have this link already, but I pulled this for you... www.youtube.com
by Reed 4/10/2011 1:01:31 AM

@Reed You can get all the pics here as well pointscope01.jp
by NHK Listener 4/10/2011 1:02:47 AM

@radioguy Wouldn't it be super fun to make nitrogen triiodide in-situ? If things are dry enough, all you need is a little shake to make it go boom.
by pj 4/10/2011 1:02:56 AM

No sheets. I made some of that in the lab in chem.
by radioguy 4/10/2011 1:03:38 AM

And now an interlude to all the drama.

AHd no idea how dangerous it was.
by radioguy 4/10/2011 1:04:03 AM

@radioguy A little is okay, a lot is, frankly, terrifying.
by pj 4/10/2011 1:05:01 AM

We made too much... luckily we broke it up before it dried. We learned later that cracking as a layer dries can set it off. I'm trying not to imagine nitrogen triiodide made with radioactive iodine.
by radioguy 4/10/2011 1:07:12 AM

@radioguy so they are introducing a potential trigger ??
by elainekirk 4/10/2011 1:10:12 AM

Wonder if the salt brine causes any mixture with it ?

Thought's ??...........

Still a little bit of smoke from #4 ?
by wtm 4/10/2011 1:12:48 AM

@radioguy We made some of that in high school also. Gun cotton too. But you can't do that no more man. Got to do it on tv.
by Jim Carver 4/10/2011 1:12:50 AM

@veenoui yeah but stumped
by elainekirk 4/10/2011 1:13:35 AM

Radiation standards for school children in Japan 1 - 20 mSv. Does this seem right? tinyurl.com
by ColorMeRed 4/10/2011 1:14:17 AM

@ColorMeRed Is that in a year?
by Jim Carver 4/10/2011 1:15:23 AM

@Reed Thank you sir, I hadn't seen that at all yet!! Watching the footage, I started by comparing the original pre accident images to current ones. Paying very close attention, it seems that the trees took on some discoloration right after the 12th/13 and again after the 23rd, and I believe that they have atrophied even more since, albeit a slow rate. Many things affect this though, the wind blowing in whatever direction (particulate accumulation) and who knows? Maybe the trees in the area develop a tolerance to certain types of radiation over time, like humans with alcohol and chemicals?
by Dennis Tucker Jr 4/10/2011 1:18:15 AM

@Dennis Tucker Jr two of the biggest releases were on the 12th and 20-21st Mar., hmmm..
by marie rich 4/10/2011 1:20:41 AM

and two more smaller blips on the 25th and 28th, if that helps
by marie rich 4/10/2011 1:21:33 AM

@Dennis Tucker Jr You're welcome. It's nice to see just how much the the light changes the view from hour to hour in that format. NHK Listener followed up the post with another link that you may want as well pointscope01.jp
by Reed 4/10/2011 1:24:14 AM

@elainekirk I think that may be their worry. Nitrogen is relatively inert only in that it doesn't burn, but it forms things that do when you heat it and mix it with organics. I'd want to be sure there wasn't still much seawater in it under those conditions, just because it's too many variables.

Dean:

How tall are those ventilation stacks at Fukushima Daiichi?

Thanks.

@marie rich @Reed @NHK Listener Yes, Thank you NHK for that link, very valuable now. I can't read Japanese but I figured out the drop box for last month and the prev/next link buttons lol. Intuition. Thanks again guys/girls!!!
