So they have followed that report why? on goj orders ? international prssure? it puts the cat amongst the pidgeons legally if it doesnt work
by elainekirk 4/10/2011 1:28:02 AM

@elainekirk good point about the legal angle. I've been assuming that NRC got impatient with things and leaked to apply public pressure.
by marie rich 4/10/2011 1:31:22 AM

There is a rider in the report along the lines of - recs are valid for the situation as it is known to us at this moment but, if they were asked to confirm and given up to the minute data and still said nitrogen then...

@Jim Carver what do you think about radioguy and his chemistry of crating amonnia, there are brine cooling/freezing systems with amonia refregernt and brine water, do nt know the paticulars of the science but had worked on several back in the early 80's.... do you think they maybe trying to create a chemical reaction to create the refregernt, they already have the salt.... or they could just being using as a purge.... the article last week did state they were looking at Air Conditiong

@fitter Hmm, let me chew on that one a bit.
by Jim Carver 4/10/2011 1:35:22 AM

Success with installing the Micro Sim Tech (MST) Personal Computer Transient Analyzer (PCTran). The simulator models a number of variable catastrophies in real time or faster. Various stand alone programs allow a wide variety of plant configurations and test suites. There is even a module for simulating the only nuclear powered de-salinization plant.
The company states that:
“PCTRAN is the most successful desktop simulator for all types of light water nuclear reactors. It is specifically designed for many different plant types, including PWR, BWR, advanced AREVA EPR, Westinghouse AP1000, GE ABWR, and ESBWR.” www.microsimtech.com
Analysis of the spread of radioactive material release is made possible by the DirtyBomb program, aka 'puff’. These programs run on windoes and after some early frustration last night, I was able to solve some dependencies and file permission issues. I’ve already blown up two reactors and seriously crippled a third, just by not knowing the controls. These babies are IAEA approved and endorsed, so you should get 'em while they’re hot.
by Jim Carver 4/10/2011 1:36:55 AM

Deirdre, I end up directly checking against file names, as they do not list when they release many things, like the files of plant parameters.
by Markfm 4/10/2011 1:37:59 AM

Before we get deep into nitrogen chemistry, let's be aware that this is nuclear chemistry, and all those chemical equations we've seen, and adding up pluses and minuses, goes out the window when you throw in ionizing radiation (think of the meaning) and transient criticalities that , whenever one happens, shift the energy level and flood the space with new neutrons. Am I right about that?
by radioguy 4/10/2011 1:40:38 AM

I was wondering how that program for the fukushima showed results for parameters in and around the plant Jim,,, and if they compare at all to what we're seeing now..
by dean 4/10/2011 1:41:09 AM

To me, the critical fact is that nitrogen in an ionic state easily bonds with either hydrogen or oxygen, and the oxidant reactions are sometimes very violent.
by radioguy 4/10/2011 1:42:50 AM

@fitter That is interesting. @radioguy just posted what I was going to say, jinx. You really can't tell what's going to happen in that environment, because we really don't know what the conditions are. so it's a crap shoot. I voiced my concerns the other day for that reason.

Some residents returning to evacuation zones near crippled nuke plant

FUKUSHIMA, Japan, April 10, Kyodo

Residents are temporarily returning to the government-designated evacuation zone near the crippled Fukushima Daiichi nuclear power plant to collect belongings needed for their new lives elsewhere, despite the radiation risk. english.kyodonews.jp

I sure hope they have rad meters,,, I can't imagine the next report... residents walk by highly radioactive particles and receive lethal dose
by dean 4/10/2011 1:44:39 AM

Dean, why do you think that we're not finding more reports about Strontium ?
by Reed 4/10/2011 1:45:08 AM

@dean I know. As soon as you see "Plutonium a mile from the plant" that's the time to get the hell outta Dodge."
by radioguy 4/10/2011 1:45:37 AM

@Reed Because TEPCO doesn't have to test for it if they're not asked, and .. um ... apparently ...uh... no one cared enough to ask? WOW that's hard to type with a straight face.
by radioguy 4/10/2011 1:47:16 AM

they have to be testing for all the isotopes but finding the data has been hard..
by dean 4/10/2011 1:48:29 AM

IAEA is sampling and DOE is as well... .
by dean 4/10/2011 1:48:45 AM

you got it radioguy,, ,and.. from the reports of fuel elements or parts of fuel elements being blown as far as a mile from what I read... it's time
by dean 4/10/2011 1:49:28 AM

@dean that thing's pretty cool. It's been the only thing to drag me away from the blog. I still need to check out DB and see what that looks like. Very fascinating. (DB, dirty bomb, aka 'poof')
by Jim Carver 4/10/2011 1:49:59 AM

@dean Would the St-90 travel as well as the Cesium did away from the initial explosions ?

@all Remeember when we were looking at those pics and saying, "are THOSE fuel rods?"
by Jim Carver 4/10/2011 1:54:55 AM

yes reed... and depending on the status of the pellets a whole lot of isotopes would be released..
by dean 4/10/2011 1:56:30 AM

@Jim Carver - Yes, don't leave us hanging, whe have had enough drama.
by Lethbridgean 4/10/2011 1:56:53 AM

Everyone.. I have just begin to make contact with the IAEA and encourage interfacing with them.. I asked for information on these isotopes from their sampling .. will see how it works out..
by dean 4/10/2011 1:57:21 AM

I encourage all of us to begin going to our sources to get information.. even DOE by using the FOIA requests.. we will find data if we all collectively begin the search

[Great, @Dean. Ditto, ALL, especially if you have contacts on the ground in Japan. Heck, even a sanitation or public works guy can hold some precious key to information. Thanks. - Alblee]

@dean Thank you.
by Reed 4/10/2011 1:59:02 AM

@dean Seems like the US is getting more antsy with the Japanese government and Tepco of late. Certainly are doing a dancing act and in the process--creating confusion.
by Jim Carver 4/10/2011 2:00:06 AM

@dean I've got a call in to UCBerkeley NUC to see if I can find contacts there that are useful.
by radioguy 4/10/2011 2:00:18 AM

@radioguy Right! That is what I remember.

by fitter 4/10/2011 2:01:39 AM

@dean sorry I mean the fuel bundles that the rods go in
by fitter 4/10/2011 2:02:45 AM

Hi everyone. Can anyone give me the link for an earlier posted site that gave a list of faults for all 6 Fukushima Daichi reactors, plus the Daini ones. All reported the same cracked coolant line amongst other faults. Some had apparently remained unrepaired since 1993. There were other cracked components mentioned too.

sounds good radioguy.. I will contact two universities I deal with ..
by dean 4/10/2011 2:05:19 AM

fitter. I think the tube bundle frame is probably stainess but could be a lighter material like inconel
by dean 4/10/2011 2:06:00 AM

@NHK Listener @dean ty if ss and or zin..... would they rust faster if out of water.... ss will rut just very slowly, but i don't know about the link from nkl.... also don't know if the radioation would have a speeding up effect if removed from water..... when they bring up ship reaked artifates they keep them summerged until they can do ? something to stabalize the metal or it accerates the rusting process (of carbon steel) it has to do with the exposure to oxygen i believe....

@all If you're like me, you're feeling like it is so sureal. I'm just trying to let it soak in..I was looking back in the archives, reuters and here also. Amazing how most of us here now were spot on. Just makes me wonder what's next? A long and drawn out battle, I'm afraid.
