@talisker Put it thise way, if you're right next to a spent rod, that's 10 000 Sv/hr. And yes #4 was supposed to be empty and that's why they say there's no problem. I can't figure that out except figures don't lie, but liars sure can figure.
by Jim Carver 4/29/2011 11:09:32 AM
@Jim Carver good to have an insight on the maximum Sv/hr of a rod. Sorry if it is common knowledge here, but want to ask where is the information for the reactor sensors coming from, are there any published tables?
by talisker 4/29/2011 11:11:43 AM
Oh but that's the spent fuel pool so yeah, that's the one that leaks but doesn't have a leak.
by Jim Carver 4/29/2011 11:12:02 AM
@talisker Tepco is the one putting out the data. It gets posted other places like nisa, but it all comes from the company originally.
by Jim Carver 4/29/2011 11:13:47 AM
Sorry, just waking up.
by Jim Carver 4/29/2011 11:14:48 AM
Jim Carver "Liars sure can figure" thats great I will remember that one
by standbybarry 4/29/2011 11:15:29 AM
@talisker The biggest worry pups right now is the SFP in #4 and the reactors in #1 , and 2 and 3 to a lesser degree. What do you bet that the brown smoke we've been seeing is SFP #4?
by Jim Carver 4/29/2011 11:18:53 AM
Ponder this.. if the reactor lid is off #4, wouldn't it be possible for the SFP to overflow into the empty vessel ?
by WolfDK 4/29/2011 11:21:08 AM
@wolf OMG ~I would say yes
by elainekirk 4/29/2011 11:22:06 AM
And #4 had the freshest spent fuel because then just took it out of the reactor. Best thing to do if you see one of those rods is to go and grab it and hold on, cuz you're already dead. 10 000 Sv/hr, that's 167 Sv/min or 2,7 Sv/sec
by Jim Carver 4/29/2011 11:23:37 AM
@Jim Carver but still, how would they get to the S/C? Because the reading is from the S/C
by talisker 4/29/2011 11:23:47 AM
tepco made a theory about #4 vessel. there is water and debris in from sfp.
by Edano 4/29/2011 11:23:59 AM
"The utility believes one possible answer is that water pumped into the spent rod pool is flowing back across the damaged gate into the No. 4 reactor well located next to the pool." www.yomiuri.co.jp
by Edano 4/29/2011 11:25:59 AM
@Edano but the pool has a leak but there is no evidence it's leaking. NHK reports ON THE SAME DAY.
@Jim Carver : maybe it was leaking, then they put kitty tape and now no evidence for leaking anymore.
by Edano 4/29/2011 11:35:19 AM
Assuming #4 SFP is overflowing into the reactor vessel, we would have a rough reading of the overflow from the SC readings, right ?
by WolfDK 4/29/2011 11:37:15 AM
the extra thing in the sfp in last picture, could that be a casket ?
by Edano 4/29/2011 11:37:31 AM
Re: Unit 4 reading -- That 6000 is mm of water (not Sv), the previous level was 4250 mm. I think that whoever is creating the graph needs to double-check their source data. If you look at the raw summary stats chart, you can see the readings for the other units are 3000mm, 6000mm,and no reading for Unit 3. See Attachment 3 in www.meti.go.jp
by Deirdre 4/29/2011 11:40:28 AM
@Edano Yeah, good ole Tapeco
by Jim Carver 4/29/2011 11:40:50 AM
@WolfDK : y'day there was a press conference they said the neutron beams came from outer space and the plutonium foundings are from bomb tests. so everything is possible.
by Edano 4/29/2011 11:41:05 AM
Good morning! Looks like we are still here. :-)
by Nancy 4/29/2011 11:41:24 AM
@Nancy : nancy, the extra thing in stolfis last picture in the sfp, is that a casket ??
by Edano 4/29/2011 11:42:44 AM
@Deirdre It says this at the top though "6100Sv/h" I copied and pasted that from above the chart.
by Jim Carver 4/29/2011 11:43:00 AM
Then again if the fuel rods are damaged which we assume they are, would it be unreasonable to believe that X amount of pellets and or debris could escape the same way ? know they wont float but the pressure and flow from a putzmeister pump surely must stir things up
by WolfDK 4/29/2011 11:43:17 AM
@Edano not seeing said picture?
by Nancy 4/29/2011 11:44:33 AM
@Nancy : the last one here, 11 posts down.
by Edano 4/29/2011 11:45:04 AM
@Edano the drawing? It looks like a lautrine toilet...
by Nancy 4/29/2011 11:45:40 AM
Is tepco still playing leaking/not leaking on #4?
by Nancy 4/29/2011 11:46:14 AM
@Nancy, nothing is leaking at Fuku its just unusual wet around there
by WolfDK 4/29/2011 11:47:15 AM
@WolfDK some random moisture, they are seaside. Nothing to worry about. Just the downstairs Olympic swimming pool they are installing.
by Nancy 4/29/2011 11:49:02 AM
@Deirdre In three it says a tame 10.6 Sv/hr, 2 is 24.9 and 1 is , well burnt to a crisp. No report.
by Jim Carver 4/29/2011 11:49:26 AM
@Nancy : don't make me sad :( it's not a toilet. this drawing could explain my question how they get the rods in and out. they put a casket in the sfp and this could be that element in the picture.
by Edano 4/29/2011 11:49:55 AM
@Edano Not sure what they are representing with the toilet. The upper corner of the SFP has racks in it up to the edge gap as do the other sides. Maybe they were trying to represent where some of the equipment for maintaining the pool is?
by Nancy 4/29/2011 11:50:51 AM
@Edano, your 3D drawings are perfect, they explained what i were getting at in a previous post
by WolfDK 4/29/2011 11:51:07 AM
@Edano Have you see such in a picture or trying to propose where they would put a casket in? From what I have read on the fuel moving process, yes, they sink the inner casket into the pool, load rods into it underwater and then pull that casket out after they seal it and put it in the bigger outer casket.
@Edano what is the offshoot from the tool pit that shows in that one drawing?
by Nancy 4/29/2011 11:53:32 AM
@Nancy : yes, that i meant. and the casket has a gate for the rods, i assume. so this in the corner could be a casket.
by Edano 4/29/2011 11:53:49 AM
@Nancy : stolfi made a bunch of povray drawings. i cannot find an explanation, but there are a whole lot and veeerrry interesting: www.ic.unicamp.br maybe this is a link to his private home drive ;)
by Edano 4/29/2011 11:55:17 AM
@Edano I would need to go back through the casket info I have. I don't think it has pictures of the loading but there might be some mention on the tour posters but it would be written in Japanese. There were some signs by the caskets that might have an illustration. Those would be in the #3 tour on my site.
