I've been around older plants and I've not see a conduit with a pneumatic inside unless t was some penetration through a wall etc. I can remember one where some FIRE WATER INJECTION lines were surrounded by a thick walled pipe 1/2 section to protect it .. but most of the time its just the old stainless tubing

@dean i am really staring to wonder about the weather

There was video of unit #4 on nhk some days ago ( from time before earthquaqe) and there was no water in core, but I dont know, maybe they fil it with water after video
by xxx 4/28/2011 1:47:45 PM

just make sure you have a place to seek shelter,, I have never been in a tornado area other than viet nam and when they said.. a storm was brewing.. you better tie up to something firmly fixed
by dean 4/28/2011 1:48:02 PM

@dean we do run them inside due to fork truck traffic etc.. or else ss heavey walles tubing... do't know where that one was located...But it did have a equpit ID tag on it
by fitter 4/28/2011 1:48:18 PM

@fitter So you have no definitive word yet on his safety? That's painful... I'm sure all is well though...
by Rob in SF 4/28/2011 1:48:23 PM

xxx.. they do lower water levels in the core to do mechanical changes.. the one that I saw was changing the spray header inside the vessel...
by dean 4/28/2011 1:48:57 PM

also fitter it could have been a modification made subsequent to when they built the place

@Rob in SF i'm sure he is VT has had some strange issue the last several years... I have five parent call before my son... so he is problably in class,,, doing engineering all his class are early

@fitter "doing engineering all his class are early" Smart man. Saves the PM to party...

@dean did you see the post top nancy .. I have a full 3x4 drawing of the evelation... now i might be able to figure some of the pipe out...

@e123 "trying but not wanting to look at the reality of what is going on, but having to. This is the worst nuclear disater the world had ever faced and will kill god knows how many folks down the line, and affect so many more. At this time there are so few voices to speak what is going on but dont be dissheartened because the truth has to be told and we can only hope the message of reality will get heared. --- No One has died. Last night, 138 people died as a result of tornados (natural weather). Lets not be melodramitic. Is this going to have a negative impact? sure. It might raise the Worldwide cancer rate for women from 37.0% to 37.001% and for men from 44.0% to 44.oo1%, lets not get carried away with are exclamations of disaster. This is still really only a regional problem. There has been no "significant" international effect as yet. Within several miles of the site, yeah they have radioactivity and radiation problems to deal with. The rest of the world has MINUTE increases (in radioactivity) to deal with.

@Rob in SF i wished he would slow down and enjoy colloge a little.. he's set on doing five years in four and he's on the deans list .... worries me to overstree..

In France (with translate google) : "Nicolas Sarkozy, who will visit next week Gravelines power plant in the North, has once again resorted to an argument summary already taken during his vows to the rural world, in January: "We're not going back to the candle ". Out nuclear power would "cut an arm, " he said.

Returning to the catastrophe of Fukushima, the head of state has held that "the accident in Japan is not a nuclear accident, it is due to the tsunami. But a tsunami in the center of France would be a novelty. " For him, "France can be both leader of nuclear and renewables. "

@dean @Rob in SF is the NCR brodcast being blocked or am i just not able to connect
by fitter 4/28/2011 1:58:40 PM

@RBeaner-if it was from patient excretion, I would think the levels would be more consistent? Instead there are these periodic large jumps/peaks. I don't know if the level of rain water/drought would impact them but they had these peaks in different seasons (August, October, January, and April). I have read that Philadelphia is down river of several hospitals, but I would think other cities would still experience similar elevations from patient excretion if that was the sole cause. The peaks are really interesting and the latest peak (post Japan) is actually one of the smallest "peaks" if you look at the historical data. They've been up near 4 piC/L 2 times (August 2010, and 3.95 piC/L in Jan 2009).

@dean ty do you know if surry can back on line yet....

@dean tink they just said seven killed VA so far, we have already had four conformed tornados and the watch/warnig goes until thee this afternoon.... going to be a wild ride in VA today
by fitter 4/28/2011 2:06:44 PM

cant find a link fitter.. I'm sure that NRC would probably intervene on that one since it was a major switchgear upset

prayin for you all

@xxx (and others?) I'm still very new so don't know if this was resolved, but it seems like it's still a bit in play. But anyway, I found this on www.physicsforums.com post #5268

I'll quote from the post:

"Here is TEPCO's latest thinking on what happened to Unit 4:

www.yomiuri.co.jp

They now think the fuel rods in SFP4 came very close to melting, and were saved from doing so by the the explosion in the building, which damaged the gate between the SFP and the reactor well, allowing water from the reactor well to flow into the SFP.

This brings up a point that I don't think had been clear previously, which is that apparently the reactor well was still filled with water. The illustration accompanying the above article shows the reactor well and the equipment storage pool both full of water:
www.yomiuri.co.jp "

I dragged the first yomiuri link through Google translate and I guess it might say what the poster says.

@momof3 I honestly have no idea of the source. This site is talking about Fukushima, and that is obviosly not the source, because last years were higher. I am saying to look at more of a local source for your high I-131 readings. It is not catastrophic levels, but it is reason for concern. If you get more data upstream, and find out where the radioactivity is being introduced then you can be more infomed in the discussion. I don't want to preach, but here I go, the government is neither the most trustworthy or exhauastive source of data. They don't care untikl it becomes an actual hazard, if then, and this isn't.. IMHO. Take samples to an unaffiliated lab, college/university if you're cheap, or an actual commercial lab. Step up! Be informed, rather than ..... ok I shut up!

by Edano via Ic.unicamp.br 4/28/2011 2:12:37 PM

@General Armchair Unit #4 was under mantainace repairs.... due to the lack of information as to 1) what procedure they were using 2) what stage they were in 3) other variables... unless Tepco or someone has "documented proof" you can not know weather the reator had or did not have water... so you have to go buy what Tepco is saying regarding the water in reator.... (BUT also the water chemistary might not have been what would normally be there for "operation" if infact they were welding underwater.. the paramitors would be set to what they need for the auto welding machines....

@dean We are having so many "warnigs on the radio" I hope i don't confuse the beeping sequence for tornadoes and NPP.... HA HA

Without providing documentation, a post (#5273) on www.physicsforums.com has this to say:

"Anyway they pumped 100t on the 20th, 140t on the 21st, 200t on the 22nd, 140t on the 23rd, 165t on the 24th, 210t on the 25th and 130t on the 26th, so it was not a one-off decision to pump more. During this time period the water level was reported as being 4200mm and 4250mm. In an earlier period from 1st April->15th April the water level tended to average around 4900mm, starting as high as 5150mm and dropping as low as 4700mm during some points. Over this period of time they sometimes pumped 180t in one go, but between the 5th and the 12th they only pumped 3 times, amounts of 20t, 38t and 90t, yet the water level only fell from 4900mm to 4700mm."
by General Armchair 4/28/2011 2:16:42 PM

@RBeaner-they stopped testing for a lot of isotopes at that location in 2006-2007, which I think would make it much more difficult to identify the source.
by momof3 4/28/2011 2:17:13 PM

@RBeaner-I realize they probably don't want to identify the source, or know the source and just don't want to disclose it ;)
by momof3 4/28/2011 2:18:33 PM

@General Armchair have you looked at the #1 blueprint in detail.... its not the same as all buildings but should still be close.... if you look at it in detail it has quite a lot of info hidden in it...... good source of base info
by fitter 4/28/2011 2:19:06 PM

@RBeaner have to agree about "truth in information" I would bet there are a lot of MEMO's being deleted that go back years......
by fitter 4/28/2011 2:21:33 PM

@momof3 Limerick PA is the only place (that I have seen via RadNet) that has routinely shown elevated levels of I-131. I too am curious of these levels, though they don't affect me. I say go test it up and down stream. Get some community action group involved to pay the minimal cost. The lab is like $30 per sample (commercial) to id all isotopes and levels. Just do it! whats the problem if it is a concern to you, and it would be of some little concern to me as well if I and my kids were drinking it.
by RBeaner 4/28/2011 2:21:36 PM

To many questions about #4... and not enought data
by xxx 4/28/2011 2:23:14 PM

@RBeaner I think that site has been in some of the reports that list it as "not a threat to public health" but has had problems.... i reconize the name from stuff i was reading... but do not remember were i say the name...
