Thanks Sin, it seems very odd that something that has regulatory oversight, critical to disaster management and needed for any modifications was not put on computer systems. Tepco's corporate headquarters should have had those blueprints in both hard copy and data files.

So finally we hear the P-word.
by Bobby1 3/28/2011 3:04:43 PM
Anyone got more details on the plutonium finding? Like amounts, are they going to release findings for other areas outside the plant?
by Nancy 3/28/2011 3:05:10 PM
I thought the thought process with the highly radioactive Chlorine isotope was that it would most likely have been produced inside the reactor(s) which were flooded with seawater for cooling before they switched over to freshwater a few days ago. Since seawater and sodium chloride were inside the reactors and had a chance to get bombarded with radiation, the chlorine isotope was thought to indicate recent leakage from inside of a reactor(s).

@Jeff I think they abandoned the idea that there was no meltdown or release themselves a while back, and are only now publicly abandoning it.
by radioguy 3/28/2011 3:05:32 PM
@Nancy @ Sin I'd never thought of that- vy good point
by marie rich 3/28/2011 3:05:43 PM
@ Jeff...The US has already withdrawn their troops away from the site and sent the women and children home. Given the financial repercussions they would not want to alarm the public outright with a evacuation, but I bet they are not drinking the tapwater, or eating the local food.
by Sin 3/28/2011 3:06:08 PM
has anyone heard news about robots to go in... france has some, so do we....
by fitter 3/28/2011 3:06:12 PM
@Sky You could be right. Either way it implies core leak
by marie rich 3/28/2011 3:06:27 PM
@Sky Except for one thing. Things only become radioactive when bombarded with nuetrons.
by Jim Carver 3/28/2011 3:06:55 PM
@Bobby1, we should not be surprised, since we were discussing the mysterious "neutron beams" since last Thursday.
by Peter Melzer 3/28/2011 3:07:22 PM
I'm still stuck on this: If they found radioactivity in soil the first time they looked for it, think how much there is around the plant.
by radioguy 3/28/2011 3:07:25 PM
@Sin I believe they're there to go to the next phase of evac. should it become necessary
by marie rich 3/28/2011 3:07:32 PM
Plutonium i mean.
by radioguy 3/28/2011 3:07:32 PM
and here comes the spin: Tepco says "no risk for health" (Reuters)
by Dom 3/28/2011 3:07:36 PM
@sin also we are very overextend...2/3 of my brother unit have been deploying the last two week for the"no fly zone"
by fitter 3/28/2011 3:08:16 PM
@Jim Carver , yeah like the icons in Chernobyl.
by Peter Melzer 3/28/2011 3:08:27 PM
Posted by Katz on his chat stream "TEPCO: Where TEPCO sampled the soil that had plutonium ->http://plixi.com/p/87602186
The issue with the CL38 is that it has such a short half0life that if you find it outside a reactor it indicates ongoing fission.
by radioguy 3/28/2011 3:09:31 PM
@all I think the facade is near the breaking point.

My heart breaks for the people of Japan.
by Debra Beckham 3/28/2011 3:09:44 PM
Can we PLEASE stop repeating the "plutonium is the most toxic substance known to man" trope? It was invented by Ralph Nader, and is NOT based upon actual science. In fact, the most toxic substance known to man is Botulinum toxin. See en.wikipedia.org and atomicinsights.com
by Joshua Diamond 3/28/2011 3:10:11 PM
@Joshua Diamond Can we say one of the most toxic, the most toxic element, etc?
by Jojo 3/28/2011 3:10:56 PM
@Joshua Diamond Good point Joshua, Thanks
by George Gibb 3/28/2011 3:11:03 PM
@fitter. What I read over the weekend was that US was sending over a couple of large heavy equipment robots that belong to the DOE. IRobot also sent over a batch of various combat and industrial robots. IIRC these are the size of their combat robots (about human sized). They have them in Japan and were working with the teams to get things set to work in the environment. They refused to disclose more citing security.
by Nancy 3/28/2011 3:11:13 PM
@Joshua Diamond And a microgram can kill you? Well maybe, at least my immune system has a chance.
by Jim Carver 3/28/2011 3:11:24 PM
Cyanide is also much more lethal than plutonium.
by borrrden 3/28/2011 3:11:35 PM
Plutonium is also a by-product in the other reactors (1,2,4) I thought, would be present in the old assemblies in all of the SFPs. That's why the Japanese have been working on their reprocessing center (not activated), to extract Pu from the old rods to use in the creation of new MOX rods. I could be wrong, but believe that is the case.
by Markfm 3/28/2011 3:11:43 PM
@Jase, one circle is on a structure with a label. Anyone knows what it says?
by Peter Melzer 3/28/2011 3:11:45 PM
@Jase So are they showing they found it in three samples. ALL THREE SAMPLES?
by radioguy 3/28/2011 3:11:54 PM
Opinion: The weight of the burden is on TEPCO. The GofJ and all of its assorted agencies have been putting pressure on the company to not only ramp up its reporting, but also advised TEPCO to find 'replacement' workers (burn out is in full force now). Good news is that TEPCO has now enlisted the help of France. Hopefully, it will open the gateway to more international expert assistance.
by Karen Warren 3/28/2011 3:11:59 PM
Another mention was Germany & France have sets of industrial large robots to deal with nuke disasters but have not sent them to Japan. Apparently the Japanese agency now in charge of industry and safety thought about creating a hazardous disaster type group of robots and just suddenly did an about face and scrapped the program. So all of their robot development has mostly been these fake human types for residential tasks
by Nancy 3/28/2011 3:12:54 PM
Any estimates of how much Plutonium was spread, and how FAR??? In the ocean? Inland in towns???
by Jojo 3/28/2011 3:13:05 PM
@ALL OPINION: I think we all can read between the lines here. If we just accept the data as given to us, I would just be appalled at the lack of ability to handle this situation. Of course they have blueprints, and of course they know exactly the condition of everything that is going on....technology has come a long way since 1986. I think this is a situation where survival of the fittest equates to the fittest being the more intelligent segment of the local populace who can figure out that they need to relocate without being made to do so...and this situation currently is one of stalling and posturing while the wealthy relocate their assets and they put measures in place to ensure their own security.
@Jojo The one saving grace about plutonium is that it can't spread far since it is so heavy.
by borrrden 3/28/2011 3:14:09 PM
@Markfm That's what I thought too. It wouldn't be just in the R3 SFP.
by radioguy 3/28/2011 3:14:14 PM
@Sin Agree
by Jim Carver 3/28/2011 3:14:32 PM
@Sin: Well put. My concern is for the average person who are just trying to cope and keep some assemblance of normalcy to their every day life.
by Karen Warren 3/28/2011 3:15:11 PM
@borrrden That's funny, California has detected lead emissions from China, which is also heavy. www.environmentalhealthnews.org
by Bobby1 3/28/2011 3:15:40 PM
What Kyodo has, not much. Can they tell the difference between plutonium from regular rods and plutonium from the MOX fuel? english.kyodonews.jp
by Nancy 3/28/2011 3:16:07 PM
Plutonium soil pollution reporting is far more relevant if they tell you how many samples at what distances it took to find it.
by radioguy 3/28/2011 3:16:11 PM
@Jojo Thus far they're stressing it's at the plant only.
by es 3/28/2011 3:16:17 PM
My heart is very heavy with the latest news. Like most of you, I have not been able to tear my eyes away from this incident since the tsunami because my mind extrapolates out the possible horrific consequences. I just want to go on record expressing love and compassion and sorrow for what is occurring and all of the human suffering that is occuring. This is such a tragedy.
