Japan Earthquake | Page 750

been in moderation since an hour, but i want to say, even if it too late now, i think it is the hot reactor vessel, but now the water has been vaporized that's why it seems hotter now than before. but possibly those tepco freaks may have forgotton some rods in the vessel. shit happens.

the reactor cap ? the metal one, not the yellow one.
by Edano 4/18/2011 2:55:54 PM

@Mexico_lurker that is about where I was thinking it is. Going to double check what xxx thought about the wall line being off on the heat image.

@Nancy look now on those two pictures and compare distance between wall and 2 big steam pipes

@all I find it a might strange they cut off the spent fuel pool in the thermal image.... isn't that what they are trying to get pictures of?
by Mexico_lurker 4/18/2011 3:00:27 PM

went back and double checked the heat image for today. If I used a shorter building width line to account for a perspective angle the heat still sits at the midline of the building.
by Nancy 4/18/2011 3:03:01 PM

I was just reading this article, and for some reason (duh) there is a high humidity level inside the #1 Reactor building. Also, I wonder if someone could tel me what they mean by the "air-locks".
by Sinthia Domina 4/18/2011 3:03:18 PM

@Mexico_lurker Yes it is odd to be cut off that much. Tepco has been doing some really odd editing of images that cut out key info.
by Nancy 4/18/2011 3:03:31 PM

@Sinthia Domina air-locks = en.wikipedia.org
by xxx 4/18/2011 3:09:21 PM

@Nancy: given Mexico_lurker overlay pic, isn't the heat coming from the steam dryer separator ? May there be a "hole" in that area that would show the water in the building basement ? This water, coming from the boiling SFP, is likely to be hot, isn't it ?

by Sinthia Domina 4/18/2011 3:14:27 PM

@Sinthia Domina: there is water boiling in #1 building, which is not vented a lot (not like #3 & #4); then humidity level is likely to be high... There may even be rain in there, as steam would condenses on walls, roof, ... #2 is likely to be the same...
by Jocelyn Mayer 4/18/2011 3:14:31 PM

@Jocelyn Mayer I agree. In the article is says that they do not know why.
by Sinthia Domina 4/18/2011 3:20:18 PM

@Jocelyn Mayer good catch! Yes, that would be the location of the steam dryer separator if it is in the same location as on #3.
by Nancy 4/18/2011 3:21:00 PM

@xxx I know WHAT an air lock is, I do not know what section of the plant has an air-lock. I am assuming the room containing the reactor itself.

This thing is perplexing me, this green structure off to the right. The fueling crane and overhead crane are both to the left off view of this. www.houseoffoust.com
by Nancy via Houseoffoust 4/18/2011 3:23:12 PM

one comment.. I will attach a document which goes into mark 1 clear up to future reactor designs. in the document this is stated "several utilities and plant operators condidered suing GE in the late 1980's after the disclosure of internal company documents dating back to 1975 that suggested the containment vessel designs were either insufficiently tested or had flaws that could compromise safety. The key concern was that the containment structure was undersized and that a potential accident could overwhelm and rupture it. the BWR Mark I CONTAINMENTS in the USA have undergone a variety of modificaittions since these initial concerns were raised. Among these were changes to the doughnut-shaped torus pressure suppression pool. Steam being "quenched" from the primary vessel into the torus under high pressure would act as a rocket and could cause vessel displacement.... netfiles.uiuc.edu

@dean I read something over the weekend that talked about a water hammer effect into the torus if some sort of drastic change happened? Similar thing?
by Nancy 4/18/2011 3:26:30 PM

@Nancy: looks like the small crane on the left, no ? (did hit enter too fast...)
by Jocelyn Mayer 4/18/2011 3:26:45 PM

Did we already know this and I just missed it?
Small amount of strontium was detected from some samples of soil and plants taken in the area that is 20-80 km far from the power station. (No date given)
by marie rich 4/18/2011 3:27:28 PM

@Jocelyn Mayer that isn't fukushima. I see what your pointing at though. Must be some sort of equipment crane over the steam dryer?
by Nancy 4/18/2011 3:27:32 PM

@Jocelyn Mayer The top part looks identical that would lean towards the steam dryer being in the same spot as 3. Now trying to figure out of the object in the right corner could hold a RPV cap or not. Still trying to determine if CNIC's image of 4's work floor is accurate or not and just from a funky angle.

Robots detect high levels of radiation

Remote-controlled robots have detected high levels of radiation inside the reactor buildings at the damaged Fukushima Daiichi nuclear power plant.

The plant operator, Tokyo Electric Power Company, on Monday released radiation data and photos taken by the US-made robots. The company conducted the survey using the robots on Sunday and Monday. www3.nhk.or.jp
The video here includes a map of each reactor showing where the robots took their measurements.

@all have to go get some work done. Will be back later today.
by Nancy 4/18/2011 3:33:32 PM

@marie rich Yes, it was reported. I posted articles about it.

@Nancy: yes, that's what I meant: looks like the same sort of a crane... Probably some equipment crane, as you say...
Me too, have to work...
by Jocelyn Mayer 4/18/2011 3:36:57 PM

@Sinthia Domina Thanks. 80km is alot more than 'more than 30km from plant'. Sheesh
by marie rich 4/18/2011 3:41:14 PM

@marie rich I know, I am looking for the article I posted that said 30-70km away,and the locations, but I am having trouble finding it now.

@Nancy that is the design flaw with the steam relief and it supposetly will tear apart the torus.... in the us they added a relief line fron the tourus to somewere.... do not know if japn did.... goes back to 90's

@Jocelyn Mayer @Nancy Some time back NKL istener had posted a article "rad control in the core shroud replacemnt Unit #2... it dates back to the late 90's and i am sure things have change in the procedures since then.... 1) do we know if "they were doing a shrould" re[acement on 4 and if so when they might have started.... if you can find this article and there is a second one that with the details ans weld procedures that are very informited.... if the were doing a shroud replace ment and depending on the stage they were in you have to go outside the box... they have to disconnect the piping system and they do quite a bit of temp changes to the reator during an outage.... these items have to come into the senerio as a variable if they were doing that work..... gotta run .... tornado issues to deal with...
