@Scilla I hope none of them happen. The constant quakes off Japan are a worry and nobody is getting any sort of reports about how the buildings are coping with them. I doubt TECPO really knows since they can't get inside to gather enough data.

Does anyone have the youtube link for the new thawk video. I saw either Markfm or Reed I think posted it last night and forgot to grab it.
by Nancy 4/27/2011 2:34:38 PM

@Scilla With a SFP that is leaking hundreds of tons of water/day, has experienced two fires, and is on the fourth floor of a building that has been subjected to a blast equivalent to thousands of sticks of dynamite...hope may be the only thing keeping it together.

TEPCO to build giant underground tank to store water? www.istockanalyst.com
by Nancy 4/27/2011 2:40:23 PM

@Reed I keep thinking through how to shore up #4 and without the ability to get under the SFP shoring it up seems impossible. They have not been able to get a good image inside the undernearth through those holes. I would not want to be the guys under there prepping the concrete molds. I wonder what the sVh would be under there.
by Nancy 4/27/2011 2:42:57 PM

@Nancy Read underground tank as "pit" down to the bedrock.
by Reed 4/27/2011 2:43:48 PM

@Reed I wonder if it has to do with the "wall" they talked about putting in to prevent radioactive water from leeching off site. I guess it is all in the marketing. Unintended leaking and run off becomes an underground tank. :-)

@Reed Just popping out of my lurker's cave to thank you for two of your comments this morning -- the one minutes ago on the 'power of hope' at Fukushima #4 SFP, and the one earlier on mankind's use of the ocean as a toilet "When will Man learn that the ocean is not a toilet for anything with a half-life longer than his own lifespan ?" -- both strike me as quite profound, and I have saved them to share with my clients and friends.
@All (esp. the regulars) A million thanks for keeping this discussion going, and for all the links and information. This continues to be my primary hub for monitoring the state of the planet following this unprecedented disaster.

@ll Here's a pretty good decay calculator: www.radprocalculator.com for online use. Looks like there's some android apps for download and this is the equation A=Aoe-( 0.693t/T1/2 ) where Ao is the initial activity, t is the time elasped since the initial activity and T1/2 is the half-life of the isotope. If you're not used to fractional exponents 'T to the one-half means the square root of T'

@Askwhy You are more than welcome, and I thank you for your kind words.
by Reed 4/27/2011 2:57:16 PM

Notice that the value will be negative, this is because radiation is coming out of the system and towards the outside. The measure of particles Bqs or Ci's are always positive, forget the US rad sheets, they're worse than worthless.
by Jim Carver 4/27/2011 2:58:22 PM

Both boards on this one:

Sayer Ji of testthewater.org was one of the people who actually followed through on Corexit testing in the BP disaster, has a video out about toxicity from Fukushima. I found it in a search for health mitigation info, and found it on this site, which is a pay site, but gives the top level, and as such, the list of things that are possibly useful, with how many references. In other words, you can get a lot of info for free. The 16 minute video lays out the lies used to hide the danger. I lve the line comparing the response to BPO and the response to Daiichi: "responding to 3 dimensional problems with 2 dimensional solutions." Flatlanders trying to understand and deal with avalanches. He gives a big hat tip to Dutchsinse.

www.greenmedinfo.com

We may want to pin the link to the video itself, but I wanted to give you the whole page (and site).

@Nancy Like someone asked yesterday, "Where in the Hell is the supertanker ?!"
by Reed 4/27/2011 3:00:33 PM

@Reed Mitubishi builds the largest tanker in the world last I heard.
by Jim Carver 4/27/2011 3:03:22 PM

@Jim Carver Irony abounds then.
by Reed 4/27/2011 3:05:00 PM

@radioguy Good one, like mountain men dealing with the ocean.

Morning dean!

@dean Good morning.
by Reed 4/27/2011 3:07:43 PM

I am reposting this for the benefit of the people who jumped in later this morning. I received this from a reporter anyone have any thoughts on the air cooled thing or the other statements they gathered? Some updated information about the plant.(updated 26th April Japan Local time)
Source of the imformation below is electricity mechanic who has been
working in the plant, and Government Official realated to nuclear
development.

<<<< 1 >>>>
One of the electricity mechanic told me that it is almost impossible
to recover the original power bord in plant2. Half of the circuit
breaker is under water, and the water it self is highly contaminated.

<<<< 2 >>>>
For plant1, it has been decided that they are going to use air-cooling
heat exchange system, instead of water-cooling system.(Government
official)They say that they will have it ready by next month, and
begin cooling the plant as soon as it arrives.

<<<< 3>>>>
For plant4, though there is no nuclear fuel rod inside the plant,
there are used ones gathered in pool to be cooled douwn.
The problem is that the main frame of the building that sustains the
pool is badly damaged by fire, and if next quake strikes the plant,
they are not sure if it could hold.
To solve this problem,Tokyo Electric Company is planning to build an
iron frame column from the bottom of the pool to prevent it from
breaking up. They say that this could be done by the end of June.
Hope that no quake will strike until then....

Radiation Readings at Tepco Plant Rise to Highest in Crisis. April 27, 2011, 5:20 AM EDT www.businessweek.com
by Debra Beckham 4/27/2011 3:08:43 PM

by Jim Carver 4/27/2011 3:09:07 PM

@Debra Beckham Re that:

"Two robots sent into the reactor No. 1 building at the plant yesterday took readings as high as 1,120 millisierverts of radiation per hour, Junichi Matsumoto, a general manager at Tokyo Electric Power Co., said today. That’s more than four times the annual dose permitted to nuclear workers at the stricken plant."
by radioguy 4/27/2011 3:10:46 PM

Adding that's more than four time the annual dose PER HOUR.
by radioguy 4/27/2011 3:11:46 PM

@radioguy - 9811.2 Sieverts per year.........
by Lethbridgean 4/27/2011 3:15:31 PM

@radioguy ty for that site. Yeah might as well drop the 'milli'. It's just Sv's at that scale. I guess they don't like the way it looks 1.12 Sv
by Jim Carver 4/27/2011 3:23:19 PM

Did we ever figure out what caused the explosion at #3? It makes a big difference regarding which isotopes were ejected at a high altitude.
by Bobby1 4/27/2011 3:23:26 PM

@Nancy , cooling #1 with conditioned air seems an odd idea. When I grew up, we used to own VW bugs. The engines were air-cooled. If you wished to visit a hot country, you needed to install an extra oil cooler and had to carry an extra-large fire extinguisher next to the driver's seat. I cannot imagine air cooling works more efficiently than water cooling and wonder why they resort to this option.

@Jim Carver, 1 Sv corresponds to 100 rem. People are acutely sick at about 150 rem.
by Peter Melzer 4/27/2011 3:26:51 PM

@Peter Melzer Yepper, no bloody nano, milli or micro here.
by Jim Carver 4/27/2011 3:28:10 PM

@Bobby Gunderson speculated on that today
by hudebnik 4/27/2011 3:28:27 PM

@ALL - I think there must be a cover-up of the rad sickness of the workers at this point. Because this HAS to be causing the non-robots to become the living dead. I think this needs to be exposed by our group. We can speculate all we want on what happened and what colour a piece of steel is, or what they should do but won't. But keeping them honest of the ongoing inpact on human life should be a focus of this group. In the end I think it would make the most IMPACT..
by Lethbridgean 4/27/2011 3:29:17 PM

@Nancy, on second thought, they might think of a water-cooled system using a cooling tower.
by Peter Melzer 4/27/2011 3:29:58 PM

@hudebnik A spent fuel pool criticality explosion would have released less strontium, than a hydrogen explosion following a corium leak.
by Bobby1 4/27/2011 3:31:33 PM

@Peter Melzer - a week or so ago there was discussion of using an air cooler water system not unlike a car radiator (or an aircon unit) but of course all this supposes that they can get close enough to anything to connect pipes etc.
by hudebnik 4/27/2011 3:31:50 PM

@ethbridgean: That is where local Japanese media outlets will come into picture. We cannot speculate or even find out any news info. sitting one ocean across. Local media has to take responsibility and state real news even if it is disturbing... Maybe, Greenpeace can play a bigger role if they get hold of some info.
by Optim 4/27/2011 3:32:05 PM

@Lethbridgean I have been thinking that for a wwhile now. These workers have got to be the walking dead and I don't think they are rotating them like they should. That may be speculation but it sure seems right.
by Jim Carver 4/27/2011 3:32:13 PM

@Nancy when the "us assesment" back in march was released they said the one of the reactors (i thiought it was one) was not getting water in the "core"... but in the contaninment vessel.... I have not heard any more and thought they had found a pipe that wounld provide water in the core... that is also about the time they started talking about using the nitrogen and air cooled system... maybe someone could look at the "US assemt" and see if my info is right and if any one has heard that they fixed that problem
by fitter 4/27/2011 3:32:14 PM

@Lethbridgean, extended hospitalizations are one way to find out. If you are suffering from acute radiation syndrome, you need a bone marrow transplant.

@Jim Carver They hide behind mixed numbers in the US. They know most Americans look at millis and meters and liters and the eyes glaze over.
