@lillymunster cooling is when ther is closed loop... but if rpv and drywell are leaking... those leaks are unfixable because extream radiation and water which cant be stoped
by xxx 6/5/2011 1:56:15 PM

@lillymunster they must inject water without breaks, because if they will stop corium can start fire and release extream hight radiation
by xxx 6/5/2011 1:57:09 PM

for unit 1 it is hard to say where corium is, it could be in drywell, but also in concrede under drywell
by xxx 6/5/2011 1:58:23 PM

@nancy the wonderful cesium capture device eh :) I think what happens is all these teoco gremlins of which they seem to have many come dashing out at night waving their arms and shepherd all the cesium to this horizontal tower where dear old cesium sits pondering the logic of a horizontal tower until all it's energy is spent and it can no longer escape

@Markfm concerning #2 temp www.houseoffoust.com the sensor that jumps up and and down is marked as malfunctioning. www.tepco.co.jp

@xxx That is what I was wondering, if they could stop watering or if there was still the ability for that to burn.
@Elaine, it seemed odd that they suddenly had this system in place and had not mentioned it before. If they can rig something that actually filters water and even removes some of the radiation it would be an improvement. But if they have to water for the next 5 years we are talking massive contamination.
by lillymunster 6/5/2011 2:01:23 PM

@lillymunster: on your webpage www.houseoffoust.com you point to japanese tepco sites, but they have athe same in english, too: www.tepco.co.jp
by Edano 6/5/2011 2:03:03 PM

this is bad if you searching for something bad, reactor 1 sfp water level from 5/16 to 6/5 measured 2 times per day: img841.imageshack.us

If we will be lucky it should drop to zero around now, and there will be fuel fire, weee...
by xxx 6/5/2011 2:04:50 PM

@edano the problem with tepco is that like with the water post I did yesterday they give only basic info in english I had to use the japanese for all the diagrams I added to the post and the diagrams are what made it so clear
by elainekirk 6/5/2011 2:05:00 PM

@xxx I believed you yesterday and still do
by elainekirk 6/5/2011 2:06:22 PM

@Edano Malfunctioning my butt. Looks to me like several drops of corium to me, the last one being a large chunk. Other sensors showing exactly where the corium fell also (rise in temps)... unless they're ALL malfunctioning which is what I'm sure Tepco would say. How about a radiation reading from inside #2 anyone?
by Dennis Tucker Jr 6/5/2011 2:06:59 PM

@elainekirk yes, but I dont understand why they arent injecting water, or there is leak...
by xxx 6/5/2011 2:07:10 PM

@xxx Because on a MCCI event, adding water to the concrete/corium mix would cause too rapid an increase of internal pressure resulting in a large explosion. We covered this back in late March.
by Dennis Tucker Jr 6/5/2011 2:08:14 PM

@elainekirk : when i compare the diagrams, they are the same in japanese and english, and i did not understand them before i stumbled over the translation yesterday.
by Edano 6/5/2011 2:08:24 PM

@Dennis Tucker Jr if there is no "skin" on corium, this is like lava, not so hot outside but extream hot inside, if there is "skin" corium can melting via concredu under this "skin" without increasing temperature and pressure
by xxx 6/5/2011 2:12:38 PM

Time for tepco to release an announcement of being ahead of schedule, all three reactors down near atmospheric pressure.
by Markfm 6/5/2011 2:12:40 PM

@Markfm "near" because of steam for clarification
by xxx 6/5/2011 2:13:58 PM

@edano are these in english now? if so do you have links ? it will make it much easier as you say
talking water problems theymust be severe tepco have published a English doc here there are diagrams in Japanese so maybe if I post the English doc then links I add under are the Japanese diagrams you techi's may be able to connect them

by elainekirk 6/5/2011 2:14:28 PM

@xxx WTH are they letting the sfp go dry? They have a cooling recirculator on it now but it still needs water.
by lillymunster 6/5/2011 2:16:08 PM

@Dennis Tucker Jr www.houseoffoust.com but you do not mean this, i think.
by Edano via Houseoffoust 6/5/2011 2:21:27 PM

@lillymunster Guys, this might relate to the MCCI- if they add water to the SFP and it leaks down to the MCCI event [haven't proven MCCI yet either although it appears obvious from the data that it is at least very close] we are back to rapid production of noncondensable gases, which would lead to an explosion. Only thing really bothering me about this theory is that they say the lower two levels are flooded already and well, we saw the steam coming from the pipe already....

@xxx I don't care if it has a skin or not. Corium is 'alive' constantly shifting, remelting etc. The heat is there whether it has 'skinned' or not. And now the concrete is just as hot.

wowee thank you so much!!!

@Dennis Tucker Jr MCCI?
by lillymunster 6/5/2011 2:25:47 PM

@Edano Thanks but yes, you are correct. I am looking for Ambient radiation levels inside the bldg or nearto the bldg- like they say #1 has 4 S/hr inside.... Any data on that at all that you know of?
by Dennis Tucker Jr 6/5/2011 2:26:16 PM

@lillymunster Molten Corium-Concrete Interaction. It's what China Syndrome is.
by Dennis Tucker Jr 6/5/2011 2:26:48 PM

Good morning! This Natural Resource Defense Council statement relayed to the White House May 26 provides comprehensive insights, particularly on the rating of radiation releases from Fukushima power station and the anticipated effects on public health. I cannot judge whether the projections are realistic, but the report gives an idea on the philosophy applied in such prognosis. The considerations on plant safety are also interesting: docs.google.com
by Peter Melzer 6/5/2011 2:28:08 PM

I believe the 4 sv reading was from a robot, it isn't anything with continuous measurement
by Markfm 6/5/2011 2:29:22 PM

Spray and Pray - New video today of the inhibitor spray operation. No more pretty blue sky or clouds on those buildings :(

I keep wondering how much these guys have been told about the radiation round there - they're either incredibly brave, oblivious... or both.

@Edano Hey man. That chart for #2.... It looks to me as if the corium DID drop, as indicated by the very sharp rise in Torus B reading followed by slow decline (as corium melts thru presumably??) over time..... Lack of info kinda keeping us from absolutely proving the melt.
by Dennis Tucker Jr 6/5/2011 2:29:26 PM

@Dennis Tucker Jr : of course. who doubts it ?
by Edano 6/5/2011 2:29:58 PM

@Markfm True, but that # is already way too high for inside a reactor bldg to ignore the fact that there is a breach somewhere. But I guess we already realize that there is a breach tho?
by Dennis Tucker Jr 6/5/2011 2:30:51 PM

@Edano Tepco does.
by Dennis Tucker Jr 6/5/2011 2:31:14 PM

there should be ~0 radiation in drywell, normally.
by Edano 6/5/2011 2:31:22 PM

@Dennis Tucker Jr They found a pipe in #1 maybe 2 weeks ago that had really high radiation coming from it. That was around the time they announced some areas of #1 were too dangerous to be near. They were going to come up with alternative work plans and shielding to put in place to protect workers.
by lillymunster 6/5/2011 2:33:37 PM

@lillymunster And then the steam pipe yesterday/Friday??
by Dennis Tucker Jr 6/5/2011 2:34:18 PM

@xxx I'm pretty sure that they must have one heck of a reason to NOT add water to that #1 SFP. Those guys don't want it to get worse if they can help it- so perhaps they can't help it....
