@Nancy, that might be where that 1 foot ground drop is at, one side of the tower is lower.by wtm 5/16/2011 8:35:53 PM
@Dean I know it's not floating on water. I wondered if they were now implying that the slag at the BOTTOM wasn't completely covered by water because of the leaks. Just wondered. Trying tovread between the lines.by LM 5/16/2011 8:36:26 PM
@Edano IIRC, it's a 9 month process just to tent #1. They first build a giant steel frame.by Rob in SF 5/16/2011 8:36:54 PM
@Rob in SF : ah, it sounded like ready tomorrow.by Edano 5/16/2011 8:37:32 PM- @Dean. So they can let the corium alone, it will cool? stop with the water, and it will cool? Then what are we fussed up about (I'm fussed up, at any rate)?by Scilla 5/16/2011 8:37:38 PM
- @Lethbridgean "explain that previous comment" I was wondering what that meant as well...by Rob in SF 5/16/2011 8:38:43 PM
@wtm I think the 1 foot ground drop is more widespread -IIRC that's how much the coast has dropped all along. I haven't seen anything that implies a specific change of level at part of the siteby UKVal 5/16/2011 8:38:50 PM- @Rob, what good are the tents ? Can't close them up, you have to let the steam out of them, or you are back in the possible hydrogen buildup situation again. So if you have tents that leak, what good is it keeping the radiation in? Nope, they are mostly just to cover up things so you can't see whats going on underneath. Just "PR" covers !!!!by wtm 5/16/2011 8:39:47 PM
@dean: I agree. Pouring water on it is like putting out a propane fire with diesel. If there were a way to feed it with dry bentonite, silica, and lime I think it would die faster.by DonnerT 5/16/2011 8:40:09 PM
Robot pics show damage in reactor building www.yomiuri.co.jp (I know this is old, just that it's nominally 16 May story)by Markfm edited by Markfm 5/16/2011 8:40:51 PM
Scilla they are on PLAN S by now.. who knows what they will do next.. not faulting but it's very complicated .. never before stuffby dean 5/16/2011 8:41:02 PM- @wtm They 'tents' are designed to be "sealed" with filtration for hydrogen and radiation.by Rob in SF 5/16/2011 8:41:29 PM
- the tents would have to have some pressure control also.. if sealed to the buildingby dean 5/16/2011 8:41:59 PM
- @Rob, that will be interesting then ?by wtm 5/16/2011 8:42:01 PM
By now they probably expect there's a healthy pool of water below where they have hot radioactive stuff. I expect they don't want hot radioactive stuff to burn through whatever steel and concrete is still there, to avoiid a big steam explosion.by Markfm 5/16/2011 8:42:07 PM
@Maureen Burke It sounds like his job, and the emergency was over. Thanks for his service.... But being the ...inquisitive person that you are, you probably want more.. If I was a tepco employee at that plant, I have no doubtt (ok believe) that I would stick around and do what I could. If I was a subcontrctor, I would run away.by RBeaner 5/16/2011 8:42:10 PM- @wtm It'll never work.by Rob in SF 5/16/2011 8:42:45 PM
- @Rob, I agree !!by wtm 5/16/2011 8:43:10 PM
- @Rob in SF Something like London's O2 arenaby UKVal 5/16/2011 8:43:18 PM
- try an experiment at home.. put a nice sauce pan on your stove and turn the control on high,,, after it gets nice and hot,, start with 1/2 cup of water and see what happens...by dean 5/16/2011 8:43:55 PM
- @Rob, UKVal, it will blow up like a baloon.by wtm 5/16/2011 8:44:03 PM
- @dean The tents are rubberized (?) fabric, so pressure should be minor issue, but that filtration system better be high-capacity...by Rob in SF 5/16/2011 8:44:17 PM
- I wonder if the new cooling method involves hiring the frost giants from Thor.by Markfm 5/16/2011 8:44:19 PM
@dean i would, but i don't know how to turn on my stove.by Panserbjorne9 5/16/2011 8:44:21 PM- But, I mean, what you said sounded like they could just let the corium "be". Wouldn't that melt on through to the containment vessel and on out? You know, the way reporting lags reality, I wonder if we're already there.by Scilla 5/16/2011 8:44:35 PM
Wow, warp speed news today! @nancy are you around?by hudebnik 5/16/2011 8:44:47 PM- lol Panserby dean 5/16/2011 8:44:47 PM
- @Markfm LOL sorry, i know we're supposed to limit commentary but LOLby Panserbjorne9 5/16/2011 8:44:54 PM
- @Markfm. The ice queen from Narnia. Kinder, gentler cooling Than Thor.by Scilla 5/16/2011 8:45:56 PM
- corium is suposed to be able to melt through and then be dispersed on the concrete floor which will tend to cool some .. only the WHAT if question that takes it out of the building.. assumption onlyby dean 5/16/2011 8:46:03 PM
- You don't think, then, that it's a case where there's a likely air gap, water below, so if the corium melts through the RPV it'll drop and contact sitting water, steam flash explosion?by Markfm 5/16/2011 8:47:21 PM
- @Dean, that what if, is the assumption the Drywell concrete is intact, but we pretty much know that these may have cracks in them, since they leak water out down there.by wtm 5/16/2011 8:48:07 PM
- (I don't have a good mental image of the water in the basement relative to the RPV, etc.)by Markfm 5/16/2011 8:48:22 PM
- @dean If you thought your life was at risk, as an RO, would you stay (and what do you think...opinion) of the rest of the ro'by RBeaner 5/16/2011 8:49:36 PM
- @dean I remember being chastised on the original Reuters blog for speculating on Corium reaching the basemat.by Rob in SF 5/16/2011 8:49:47 PM
- @Markfm Yes I wish I had a better understanding of the 'basement' layout etcby UKVal 5/16/2011 8:49:54 PM
- Markfm. I don't either. I know the turbine rooms are flooded. Are the basements flooded? Are the SC's covered in water?by Scilla 5/16/2011 8:50:05 PM
- the other day i calculated the corium volume. it think it was like ~20 m³. this is like ~ 1 mheight in the vessel, a bit more because the bottom is round.by Edano 5/16/2011 8:50:14 PM
- I'm reading about water in the basements of 1 and 3 both, pretty sure 2 also had it.by Markfm 5/16/2011 8:50:52 PM
- Your math from the other day seemed correct, basic volume calculation.by Markfm 5/16/2011 8:51:38 PM
- @Markfm yes I've read that too, but I still can't visualise how that relates to the containment vessel, RPV etcby UKVal 5/16/2011 8:51:52 PM
- Dean. I think the Corium has left the building. Or, Maybe it was Elvis. Now I'm not sure :)by Scilla 5/16/2011 8:52:13 PM
- @Markfm : cannot find it anymore, but i think that was the result.by Edano 5/16/2011 8:52:19 PM
@RBeaner - Who are you talking about? the guy that died? He had just started! His job had just begun! Let me see if I can dig up a job posting...btw- early on I read that they were hiring homeless people. Most recently, I read that they were having trouble keeping workers at the plant. I'll post links once I gather them, Beener. And, yes, I am very inquisitive.by Maureen Burke 5/16/2011 8:52:22 PM- RBeaner what I am used to is.. the evacuation system monitors showing that evacuation is needed then every one evacuates.. We have a remote emergency control center and from there plan the re-entries to do anything... once that is set up I would be involved in re-entries.. but it gets to a level of VOLUNTEER onlyby dean 5/16/2011 8:52:38 PM
