@Jim Carver i guess i misspelled the proper plant name by accident and the softwere thougth i was swearing

@Jim Carver Has there been any thought or discussion here about the possibility tha #3 explosion may have occurred OUTSIDE the plant, say in the exhaust pipes that carry stuff to the stack? I note that the big exhaust pipes lie mangled and busted on the ground next to #3, though mostly look intact next to #4. The fireball seems to start outside the plant, and after the initial burst it even gets sucked INTO #3 building -- at any rate there is no large follow up along the building -> fireball vector, just the strong vertical explosion that follows the fireball. If memory serves weren't they trying to vent hydrogen gas from #3 when the explosion occurred?

Hmm, speaking of which, is it possible that when venting steam they would send it up through the stack?

@dean same here

@dean still could not get the one link to open, but the srould replacement was good and changes the procrdure of the first one i saw...hey i'm getting good at typing in the dark/dim lights

@dean the one you posted this moring here them put above karro

@dean did you ever get a chance to look at the srould replacement article that used the mrchanicl fit ups at (i think it was the water jets) instead of welding them out

Yup, the 2 NISA reports (118 and 119) list the same 6:00 #s.

@General Armchair now that i have a full size drawing, like to color code everythig... i want to try chasing the systems as best i can.... i think (need to review the layout) that i have suspicions about the first explosion at #3 and were it started... the evlev drawing has lots of good infor if you enlarge it and chase the equipmet layout in respects to the vedio and still pics.....

@dean No kicked me out and stut my wireless off again... its only that site

From JAIF, "Tokyo Electric Power Company now says it is unlikely that water is leaking from the spent fuel rod pool of the Fukushima Daiichi power plant's No.4 reactor." Has anyone seen anything newer contradicting this? Personally I don't see how it is possible unless there is a heck of a rod load in #4 SFP, and it doesn't square with the > 5m of water in #4 basement.

@fitter Did you see my comment to Jim Carver before he left? I was wondering if the idea of #3 explosion originating OUTSIDE the building had been considered. My comment is below, still on this page.

@markfm Yes, there was yet another announcement about 10am CST saying again yes it is leaking. They can't make up their minds.

@General Armchair i have been gone for four days and way behind on the info, but the air system on some of the buildings sit to the offset side and (maybe the main system maybe the begining of the secondry system.... don't know which side it is on building3 but i agree that the system needs traced before "shot down"

@Nancy have you seen the skimmer tank in any of your pics...,

@dean @Nancy are you two going to be here a mimt.. need to put on coffee.. but wnated to ask you two and any one else something

@Markfm, temp is down on #1, but looks like pressure is up a bit, what you would expect, but still no increase in where the water levels have been in the RPV, makes you wonder if there is a pipe broken at that water line, and they can't fill it up any higher. Also keep an eye on the "CAMS" (Radioactive levels) for #2 & 3, they seem to be going up, and it is showing really high readings in the SPV and DW, places it shouldn't normally be hot.

wtm, I'm seeing CAMS in 2 continuing down, though nothing like that huge, unexplained, drop in S/C B reading yesterday. Also looks like a slight decrease in #3 radiation. #1 pressure does seem to show a slight decrease, too. This is comparing the 6:00 28 Apr data to the 6:00 27 Apr data.

@Markfm, really hard to get a good consistant reading from anyone, if you look at all the agencies and TEPCO for the same date and time, they will all be different a bit. Makes you wonder if you are really getting the correct info ?

@dean @nancy now that I have a real drawing..... i need to do a lot more looking, but you may be able to set me in the right direction... they list several pieces of equipment that are on the outer walls... deminerlizer tank, skimmer tank, precoat ank and cooler.. etc.. was wondering how much Radiation these would still show on thermals if they were now outside the building.... also there is a filter sludge reciever tank.... collection drum, ( i think the drum shows in one of the pic's..) but the sludge tank and items like it that are used to maintain the water chemesity.. acorrding toe the infor i read... remove the decay/contaiment to keep the chemisty correct in the pool and reactor.. these should have "waste" that might have been propelled it the equipment was or if the equipment was outside... what type of heat signiture would they show.... would it even be detectable ??? how about rad readinging if it got spread on the ground???
