I hear it is at chernobyl.. at as you can imagine a huge cost and time effort.. it is supposed to be the largest movable structure ever built

@Dean Just look at NASA's shuttle transporter..... same thing.
by Dennis Tucker Jr 3/26/2011 3:22:59 PM
@Dean: In a few weeks they will declare the situation as "stable" (even if might not really be), and the media will stop reporting, so we won't know what'll happen afterwards. They will probably spend a couple of years trying to clean it up after.

Between 5:35 am and 4:05 pm on the 24th, 120 tons of sea water was injected into the SFP of Unit 3. However, between 1:28 pm and 4:00 pm on the 25th, water was sprayed by a fire truck. Injecting water via the coolant system must surely be a better and more efficient way, so could this indicate that those systems are not working as they should? Source: www.meti.go.jp (in Japanese)

@Dawn Here is a link to CDC that refrences water treatment, etc. www.cdc.gov

I would have to have other articles on removing radioactive iodine from water to be safe
by Dean 3/26/2011 3:24:36 PM
@Dean Thanks for the link to the CNIC MOX dangers report. Here's the part that jumped out at me: "When MOX fuel is burned in nuclear plants designed for burning uranium fuel, many safety problems arise. For example, the control rods worth are reduced, the emission of radioactive gasses increase, and difficulties arise due to the lower delayed neutron ratio. (See International MOX Assessment report published by CNIC.) Using MOX fuel which is of a low quality, or which exceeds the reactor's design criteria, further increases the likelihood of accidents. "

@Dean, I think they will still be working on containment in a year from now :(

I said it last night, but I'll mention it again. Some of the brightest minds in the world are on the ground or in a supporting position. It's inherent to its culture. Japan is a proud nation. Not going to go religious here, but pride is the greatest sin. It took Obama 5 days to call the PM of Japan. After all that I've learned over the past two weeks, it is now beginning to make sense. US wanted to know what was going on at Fukushima. GoJ wasn't 'forthcoming' with its answers and still isn't.

By the way, in units 2 and 4, seawater is being injected (as opposed to sprayed).

@George Gibb; @Ralph Unger : TYVM for setting this up, i love this format. I'll be here around the clock checking the news and trying to provide useful info. when relevant. Thanks again!

@kb: Pumps are not working. What is the date of that report? I thought that they converted to fresh water. Anyone?
by Karen Warren 3/26/2011 3:27:04 PM
mox was loaded last fall ~ what I do not understand is why there would already mox in the spent fuel pool for reactor 3, isnt the fuel used for years?

@Karen Warren ...yeh, but I'll bet GoJ didn't know themselves because TEPCO didn't know themselves but had an awful suspicion...
by MaryMary 3/26/2011 3:27:18 PM
@kb they can't start again the cooling system, because high radioactivity water on the underground: since yesterday, they rely again on external pomps

Here is the (more detailed) report by a water purification company, Lenntech, on iodine in drinking water and its removal. www.lenntech.com

I feel like developments are moving at a turtle pace. I'm very concerned about what is going on over there- all of this plutonium talk, etc. Japan would almost be uninhabitable after this, wouldn't it?
by stef 3/26/2011 3:27:43 PM
Dawn, still on the subject of drinking water, from my understanding iodine is fairly easy to remove. What scares the life out of me is what happens if the other heavy metals get into the water.
by Janis 3/26/2011 3:27:53 PM
@elise There was not any in the spent fuel pool.
by borrrden 3/26/2011 3:28:06 PM
@Karen Warren We're all trying to determine the picture, when we have just a few pieces of the jigsaw puzzle.
by Bobby1 3/26/2011 3:28:10 PM
first comment here... George Gibb thank you for this. @dean, that MOX story is a very disconcerting read.
by nls 3/26/2011 3:28:19 PM
I enjoyed this Fukashima/Chernobyl comparison. www.spiegel.de
can anyone diredt me to a link to convert atmospheric pressur, kPa vs. mpa?
by marie rich 3/26/2011 3:29:25 PM
@ Dean at 8:06- Thanks for the link to the 'abovetopsecret' article. Interesting read. I have friends in Tokyo with a 4 month old infant, and I will be sending the link on to them. Thank you, very much, for the time you take to contribute to our knowledge.
by JPH 3/26/2011 3:29:47 PM
the physics of operating with MOX fuel had to be compensated for by the content or ration of Uranium oxide to plutonium oxide so, the plutonium is lower on percentage content to make the fuel act like uranium then compensated for in the reactor
by Dean 3/26/2011 3:29:49 PM
@radioguy Maybe I can find the link, but one scientist reported that only about 1.5% of the plutonium in MOX actually undergoes fission and it is put in there to thwart terrorism because "it is too hot to handle" ???
by Jim Carver 3/26/2011 3:30:03 PM
@dean - I'm a little perturbed at the fact that reactor 3 has been "stable" pressure for some time now. Is it possible the level is "stable" because of the loss of containment? I would think with the immense changes in temperature it would be impossible to achieve stable pressure without venting of the chamber (which they have said they have not done recently) I would imagine a small leak in the reactor would give a stable reading because pressure can't build.
@Jim: I thin that it's in the white paper report that Bev posted last night.
by Karen Warren 3/26/2011 3:30:47 PM
Thanks, Dean & Janis - I am concerned as well with the safety of our water. It's all the same world; we drink the same water, eat food that relies on that water, and breathe the same air. As I understand it, water is the only substance that boils at 100C, and so distilled water would likely be 'pure'. But I have a really lousy concept of chemistry, so I may be wrong...
@Dean : I don't think you are the Dean who posted previously at reuters and here this morning. May be a paranoia, may be i'm right. Because your way of thinking seem to have changed ...
@I don't know, may be someone wanting to have respect, or audience.
by futureisnow 3/26/2011 3:34:55 PM
From yesterdays report Union of Concerned Scientists ~ Unit 3 reactor vessel, the Unit 3 containment building, and those pressures would seem to suggest that the reactor vessel is still intact, because the pressures are different. If there had been a substantial breach, those two pressures would have equalized over time. So, it's contradictory data. I think that's reflective of the situation over there"
by elise 3/26/2011 3:34:56 PM
future: the forum is looser than Reuters, i.e., more relaxed.
by Karen Warren 3/26/2011 3:35:24 PM
@dean the links you gave, for instance. there is a lot of differences.
by futureisnow 3/26/2011 3:35:26 PM
@futureisnow I think here Dean has a little bit more latitude than he did at Reuters so he is more freely sharing information/opinion perhaps.
