Check this from the 21st and 22nd:
MARCH 21, 9:40 PM
Radioactive isotopes of cobalt, iodine and cesium are found in seawater near the discharge canal of the reactor.
MARCH 22: 11:00 PM
Like the day before, radioactive isotopes of cobalt, iodine and cesium are found in seawater near the discharge canal of the reactor.by RadioGuy 8/28/2011 8:49:27 PM- Isn't that when we saw that big radioactivity spike...22nd 23rd of March?by RadioGuy 8/28/2011 8:49:59 PM
Just on the side, note the smoke hovering over the reactor buildings. Highly radioactive and seemingly not all going out to sea!by Peter Melzer 8/28/2011 8:50:37 PM- @Peter Melzer Like the fog that's always hanging around the site these days.by RadioGuy 8/28/2011 8:51:39 PM
@M.I.A. How these events could possibly be related is anyone's guess but it seems we can't yet rule out a connection between the crushing wall damage that still bothers us and the noise of a loud explosion from somewhere in the plant, possibly Unit 2's SC.
@Edano Can your magic plots tell us anything here?by es 8/28/2011 8:51:49 PM
@RadioGuy that is for #4 also? All that excess radiation out #4 into the sea sort of goes against the #3 is the sole cause theory.by lillymunster 8/28/2011 8:52:49 PM- Yesby RadioGuy 8/28/2011 8:53:01 PM
- That's from the R4 status update.by RadioGuy 8/28/2011 8:53:18 PM
- We know for a fact #4 was hot, boiled dry and was burning off and on. So maybe the top looks fairly pristine because the fuel never itself exploded and wasn't the point of ignition?by lillymunster 8/28/2011 8:54:00 PM
- Though R3 says the same. so maybe they share a discharge? Or they're close?by RadioGuy 8/28/2011 8:54:08 PM
- As in it had fuel melting, created the hydrogen but wasn't where it ignited. THere was also welding equipment in the building and possibly a solvent tank that could have added to the explosion.by lillymunster 8/28/2011 8:54:52 PM
@lillymunster a piece of metal just getting hot can 'jump' so a piece of equipment getting radioactively hot would 'JUMP' and if it hit anything else metal as it 'jumped' ie inner framework the sparks would ignite the hydrogen?by elainekirk 8/28/2011 8:54:53 PM- @elainekirk oooh.by lillymunster 8/28/2011 8:55:53 PM
- I need coffee..:-)by lillymunster 8/28/2011 8:56:03 PM
- @lillymunster The melt diagrams from the three reactors show that even the minimal cooling (neutron diminishment) of being on the periphery instead of the middle pushes the middle to melt first. The top of the pool would be the best cooled of everything that was exposed by the dropping water.by RadioGuy 8/28/2011 8:56:14 PM
- We need one of our nuclear engineers to thumbnail the amount of cladding that would need to react to create that much hydrogen (and at what time you start getting it producing oxygen as well) and whether the reaction would stop when the fuel was cooled again. I assume it was compromised but not breached, but who knows. The possibility of damaged assemblies in R4 complicates things immensely.by RadioGuy 8/28/2011 9:01:17 PM
- Am I wrong to be paranoid that we've seen no revelations abut R4 amidst all the TEPCO Confession and Bowing Sessions?by RadioGuy 8/28/2011 9:03:16 PM
- it would be good to know where the old shroud wasby elainekirk 8/28/2011 9:03:35 PM
- @elainekirk Yes it would.by RadioGuy 8/28/2011 9:03:57 PM
G'day @allby hudebnik 8/28/2011 9:05:07 PM- @RadioGuy long ago I found reference to extra storage being applied for tepco wanted to store in 4 but we couldnt think where they would storeby elainekirk 8/28/2011 9:05:24 PM
- Do you think the SFP Cs figures that Arnie G found a couple of days ago shed any light on things?by hudebnik 8/28/2011 9:05:46 PM
- @hudebnik greetingsby elainekirk 8/28/2011 9:05:49 PM
- Hi @Elaine - we're at opposite sides of the globe at the moment!by hudebnik 8/28/2011 9:07:34 PM
- Hmm. the ones from August. ?by lillymunster 8/28/2011 9:08:25 PM
- @hudebnik are you visiting down under?by elainekirk 8/28/2011 9:09:23 PM
- Don't relative levels of Cs-137 and Cs-134 tell you a lot about how long ago fission stopped? They might be useful that way, though the measurements would have to be pretty precise to get anything meaningful this close to the event, I suppose. Beyond my skill set.by RadioGuy 8/28/2011 9:10:05 PM
- @Elaine - I'm in NZ visiting our daughter and familyby hudebnik 8/28/2011 9:11:35 PM
- I'll post Gundy's stuff in a minute, just finding it on a v. slow connectionby hudebnik 8/28/2011 9:12:16 PM
- @RadioGuy I think that might be a Dean question..by lillymunster 8/28/2011 9:12:49 PM
- @lillymunster Yep.
OK, I'm off for a while.by RadioGuy 8/28/2011 9:14:04 PM - This is the Tepco document www.tepco.co.jpby hudebnik 8/28/2011 9:14:20 PM
- Maybe somebody could pls unlock it and post the contents? I'm on minimal facilities here!by hudebnik 8/28/2011 9:17:33 PM
- this doc could be useful it isnt your usual spent fuel doc docs.google.comby elainekirk 8/28/2011 9:18:08 PM
- @hudebnik just doing itby elainekirk 8/28/2011 9:18:49 PM
@hudebnik is this what you wanted done ? :) www.tepco.co.jp
by elainekirk 8/28/2011 9:20:45 PM- @Elaine - TY!by hudebnik 8/28/2011 9:21:49 PM
- We need our experts on this but two things struck me - that #4SFP Cs is surprisingly low if there was any recriticality there, and that #2 is very high. The Cs in #2 can't have come from debris from the explosion in #3 because #2
still has a roof.by hudebnik edited by elainekirk 8/28/2011 9:26:35 PM - Like most things from Tepco, curiouser and curiouser...by hudebnik 8/28/2011 9:28:17 PM
- @hudebnik as alice said ...by elainekirk 8/28/2011 9:31:22 PM
- @you reading the temps in the spent fuell doc suprised me as a non techiby elainekirk 8/28/2011 9:32:06 PM
- @Elaine - which temps?by hudebnik 8/28/2011 9:35:39 PM
- BTW our daughter here in NZ is called Alice ;)by hudebnik 8/28/2011 9:36:26 PM
- @hudebnik my youngest was going to be alice but somehow she became Jennyby elainekirk 8/28/2011 9:49:07 PM
- I'm going to take a break now - may pop up (much) laterby hudebnik 8/28/2011 10:08:56 PM
