Secondary pressures should be 75 PSI, anything over that might lead to leaks.

@talisker I just find it interesting that he included Fukushima in the statement that the "main lesson of what happened at Chernobyl and the most recent Japanese tragedy as the necessity to tell people the truth".
Does that not say that Medvedev believes that GoJ and TEPCO are not telling the truth? Has any other world leader made such a statement?

Containment nominal design was 75 psi, about 5 atm (not sure if that is gauge or absolute). Unfortunately it doesn't work since the earthquakes -- #1 was leaking before they reached 200 kPa, 2 atm.

@RBean Maybe, probably, but you still have to look at what they are putting out to have some basis to make a fair judgement. I don't 100% buy those graphs down there, but it does give a place to start.
by Jim Carver 4/25/2011 4:57:37 PM

@RB I respect your viewpoint. But most Japanese are used to reading between the lines. It is a fact of life there. For reasons I have already mentioned.
by Ralph Unger 4/25/2011 4:59:22 PM

@Ralph Unger ditto
by Jim Carver 4/25/2011 4:59:45 PM

@RBean : the japanese society is very conformist, especially when you exclude "extremists, enviornmentalist or whacko". there are no non-conformist journalist, except "extremists, enviornmentalist or whacko".

#1 core beats me. Nominal design, operational, is up around 7000 kPa (70 atmospheres), and it is supposed to have a decent margin on top of that. The thing is, how much damage is there to the RPV, and particularly to any penetrations? As IAEA clearly states, #1 - #3 are not at cold shutdown points, #1 pressure continues to rise, though slowly. I'd expected them to try knocking the pressure down, a planned venting -- either they cannot or they have faith that it is structurally sound (yeah, right...)
by Markfm 4/25/2011 5:00:28 PM

It has been argued that #3 explosion may be a nuke blast in combination with hydrogen, so here a question from me, based on the graphs and other partial info from the past on the pressure vessels, if #3 had exploded, would we still see several atmospheres pressure developing in there?

I'm going to take the liberty to rewrite the headline for this story: "Russian President Dimitri Medvedev to Japan on Chernobyl Anniversary: 'Tell the truth'" www.bbc.co.uk

@UKVal the cryptome link is 404. Need to go hunt down tenzig's post.

If you are Japanese, what is unsaid is as important as what is said. That is important in reading Japanese articles.
by Ralph Unger 4/25/2011 5:03:14 PM

@talisker : you are right, that is the question.
by Edano 4/25/2011 5:03:55 PM

@ Nancy - trying to post link again cryptome.org

be back in a bit
by dean 4/25/2011 5:04:00 PM

@talisker #2 and #3 cores are actually at a slight vacuum -- core pressure a bit below atmospheric. I don't know of anyone who has been claiming a nuclear explosion (at least not anything more than some material being ejected when it initially exploded, which is not a nuclear explosion)
by Markfm 4/25/2011 5:04:38 PM

@talisker : of course, there would be no pressure left if the containment exploded. either the theory is wrong or the readings.
by Edano 4/25/2011 5:05:50 PM

@UKVal The link keeps failing. If you can tell me what set from Crytome and what number of image on the page I can go take a look at this. The original person that Tenzig quoted seems to honestly be just babbling nonsense. The piping exposed is just lower level routing by the catwalks. It isn't piping of the reactor. It is right next to the wall. So his claim that "omg I see pipes" means nothing because he is misunderstanding what he is looking at. I do want to look at the cryptome images specfically in question to double check but I think the person that originally wrote that has no clue what they are talking about.
by Nancy 4/25/2011 5:06:45 PM

@Nancy I get the index page. Now where?
by Jim Carver 4/25/2011 5:09:13 PM

@Jim Carver ???
by Nancy 4/25/2011 5:10:06 PM

@Nancy The first page, where to from there?

@Jim Carver on what site? you totally lost me.
by Nancy 4/25/2011 5:11:55 PM

@Markfm well, interesting because a few pages back I was called argumentative for supporting that if the #3 core was exposed we would be seeing a completely different scenario (in response to James Ward). That said, I can't tell if the drywell is intact or the pressure vessel has no damage. These giant "kettles" have pipes going in and out all over and those pipes are now certainly broken and leaking.

The link posted by @UKVal. I thought you were having probs.

by Jim Carver 4/25/2011 5:13:47 PM

I dunno but these numbers do scare me. atmc.jp
by Ralph Unger 4/25/2011 5:14:22 PM

@Jim Carver Keeps posting a cryptome link that goes nowhere. I just need to know what collection of images on cryptome and what number for those images in that collection so I can go look at them.
by Nancy 4/25/2011 5:14:54 PM

@Nancy I'm not having any problems with that link. @Ralph, did you see 4? To the limit of the scale straight across.
by Jim Carver 4/25/2011 5:21:19 PM

A new hydrogen blast at the plant would not necessitate an extension of the exclusion zone roughly 12 miles around the facility, Japan's Nuclear and Industrial Safety Agency indicated on Sunday.

"Another hydrogen explosion (at the plant) is one possibility that we can think about," NISA Deputy Director General Hidehiko Nishiyama said. "Even if that happens, I don't think we need to change the current evacuation zone." www.globalsecuritynewswire.org

Anybody else having problems with the fukushimawikispaces pages? Not responding!
by hudebnik 4/25/2011 5:27:36 PM

@Jim Carver I finally got it to work. I do not see anything in those images that show containment is gone as in a visual piece of it is gone. The original person did not specify visually or even really with a discription other than the sighting of pipes exposed on the 3 & 4th floor. Those pipes are not the inside of the reactor, they are on the outer wall of the building frame.

@Nancy K cool. Wanted to see if I could snag em all, but the dir of ~/daiichi-npp/ is 403, forbidden.
by Jim Carver 4/25/2011 5:32:00 PM

@Nancy How much of that has been archived? If you know.
by Jim Carver 4/25/2011 5:33:03 PM

@ Nancy -the person may have babbling - the issue for me was the 2nd pic in the link which showed the object on the roof of #4 from an angle different to those I had seen. However you may have seen that pic before
by UKVal 4/25/2011 5:33:12 PM

@Jim Carver I have all or almost all of the cryptome images saved. I need to go through and do a final double check to make sure I have all and I was going to move an archive over to your server along with the videos and articles I nabbed in the last week
by Nancy 4/25/2011 5:34:31 PM

the photo is headed 24th march ( added 2nd April)
by UKVal 4/25/2011 5:34:51 PM

@UKVal yes, that angle has been nabbed and added into things.
by Nancy 4/25/2011 5:36:16 PM

haha, just remembering the "floating pool" ? where is it by now ? was it just a tepco fantasy ? www.aargauerzeitung.ch
by Edano 4/25/2011 5:36:58 PM

@Nancy I have the fukushima.faq page in there. If it's in there, then it's there. Reason I don't know is because there's too much to go through and the only way I would know is if I did a search. Just to let you know :)

@Nancy Not that I would be worried about any redundantcy anyway. We've got lots of space. Load it up!
by Jim Carver 4/25/2011 5:42:12 PM

@Edano They had the super float there for a few days. I remember seeing images. But were they talking about some sort of giant floating pool they were going to have made and set it up in the ocean?
