1- fission gasses can be released.. even in spontaneous fission
by dean 11/5/2011 1:20:06 PM

@Dean, excellent idea about the radiometry on vehicles from earlier.

2-heat flux generated from the fissions, unless removed, can reach the heat can reach the critical heat flux level where boiling would occur. heat transfer becomes extremely complicated to analyze

too bad that the decay lines do not end with gold - would make it easier.
by Edano 11/5/2011 1:26:24 PM

3. corrosion can cause stress cracks in the metals, chemical interaction with remaining cladding causes accelerated degradation of cladding and release of fission products..
by dean 11/5/2011 1:27:32 PM

@ Edano.. you mean wait long enough and then just mine the gold.. yeh

4-It has been shown that iodine causes the rate of cracking in pressurised zircaloy-4 tubing to increase
by dean 11/5/2011 1:28:51 PM

In looking for news this morning I noticed a trend all week where power industry trade news sites are all making the same proclamation, that fuku is in cold shutdown and the conditions are perfect for commercial nuclear power to run ahead with new reactors etc. Either they are not paying attention in Japan or this is a self preservation technique hoping if they keep telling the same PR statement enough investors won't flee?
by lillymunster 11/5/2011 1:29:40 PM

@Dean, MIA mentioned yesterday that she found a series of isotopes that decayed into the xenon in question and one of the initial isotopes was I-131. TEPCO keeps posting it as none detected with a footnote that they are using a rather high threshold of where they consider it none detected. So there is I-131, TEPCO is just playing games about the existence. This might explain the iodine in rice if some factors like a release and wind dumped a bunch on that rice field? Or maybe that field was in a constant wind path from the plant? Of course we didn't get details on where exactly the field was.

So could all these corium reactions account for the increasing hydrogen in 2?
by lillymunster 11/5/2011 1:33:33 PM

@lilly.. cold shutdown is when the temperature of reactor vessel remains at a specific temp... that's about it.. in my opinion it has nothing to do with the nucleonics or physics of the core and is as if the fuel were out of the picture.. all the fuel does is generate heat and slow up the process to cool..
by dean 11/5/2011 1:33:51 PM

@dean yes, it seems to be being abused to imply more than that via the media and various PR people including TEPCO. As if it means safe, stable etc.
I didn't realize how much new understanding came out of Chernobyl. Makes me wonder what new surprises they will find when they can finally go inside Fuku.
by lillymunster 11/5/2011 1:35:39 PM

@lilly.. if you could remove all of the parts of the building that do not contribute to hydrogen generation I'm thinking you have piping with pockets of trapped hydrogen and that as the result of interactions in the corium..
by dean 11/5/2011 1:35:56 PM

@lilly,,, they can't even say the reactor is shutdown now... they have no idea what the Keff is in the cores,,, it was <1 initially when all the safety rods when in .. and the reactor was subcritical.. but since then explosions, melts etc have occured and so things are very unstable..
by dean 11/5/2011 1:37:45 PM

@Dean, sidenote from yesterday. The woman that owns EDI, the company that does RadNet maint. She was getting DOD/Army contracts when she was undersecretary of DOD for personnel. OOPS. They did overlap. The hubby thought they were in violation of what he had been told at work as far as conflicts etc. If she had retired/left and then gotten them it would be no big deal but I do think she did violate federal rules. She was employed there into 2009. I can compile what I found into notes if you want to take a look.

Edano says dump nuclear in Japan but sell it elsewhere:
(Asahi Shimbun) 28 minutes 05 November 2011 20:00
Economy, Trade and Industry Minister Yukio 枝野 5th, nuclear exports have stagnated after the earthquake East, announced that the opinion should be requested from any other country exports. In the lecture at Waseda University in Tokyo, "the answer to foreign technology assessment is now our country has, but rather an international responsibility," he said.
枝野 said, the risk of nuclear power pointed out that while there is also positive aspects. "How much emphasis do vary from country to country risk. Some countries do not have earthquakes and tsunamis, Japan is by far not suitable for nuclear use," said the new location of nuclear power in the country is negative showed idea.

@lillymunster wow !
by Edano 11/5/2011 1:45:10 PM

I would like to see it.. I have already sent off an email to my senator
by dean 11/5/2011 1:45:42 PM

I hope that table shows up ok..

I will put it into a peer review document and post the link here.

Prof Kodama doing rad surveys in Fukushima to show prefectures how radiation isn't linear but hot spots so understanding can be realized.

@all - I have the update to the condensate tank article done if anyone wants to give it another look and let me know if it is ready or not.

news.goo.ne.jp Trade and Industry Minister 枝野 two days, as of late prime minister's call to NISA of METI issues radioactive xenon was detected in Unit 2 TEPCO's Fukushima Daiichi Nuclear Power Station, "available for fission There was also conveyed to the situation immediately, "the president noted in verbal and 深野 Hiroyuki security.
Revealed at a press conference two days Fujimura Chief Cabinet Secretary. Fujimura said, but NISA TEPCO received a call from a day at midnight, was secretary to the prime minister to call at 7:00 am after two days. Noda says Secretary to Prime Minister immediately reported.
NISA is "on or about not being able to find a tentative detection of the xenon, by itself, result in immediate danger from the temperature of the reactor was determined not to" have it explained.

There has just been a tweet that fukushima diary are reporting 120,000 bq in a schoolyard on phone so unable to follow it up

@elainekirk can they get any comment on location?

Here is the link for my documentation on Bradshaw and the DOD contract. Dean did you get this?

@all - after MIA gave me the hint to get into old EPA graphs I am making a list of all the stations that were out of service during March-June. The list is pretty big and I am not even half done.
by lillymunster 11/5/2011 2:18:38 PM

have it lilly.. ty .. be back
by dean 11/5/2011 2:22:20 PM

Have a good one Dean!
by lillymunster 11/5/2011 2:25:02 PM

Something I am noticing with radnet. Stations near major US installations or close to Washington DC all work. The ones that don't work are everywhere else. I also noticed that between the link MIA gave me to get into the original data vs. what you see if you look at those graphs through the normal EPA website links is a different graph. The new ones show readings when the stations were out of order and have multiple colored graphs. I have to wonder if this is the data provided by NEI in these new graphs. It would also explain why the new data doesn't show the spikes some of the original working radnet sites did.
by lillymunster 11/5/2011 2:34:34 PM

@dicko will go look
by lillymunster 11/5/2011 2:44:31 PM

Hard to say for sure but that looks like smoke or steam down by the common pool building. It is 11:46pm there. A bit early for fog, we usually see that roll in during the early morning but depends on the weather also. I did notice we are still seeing radiation flashes on the camera.
by lillymunster 11/5/2011 2:47:31 PM

They have the big spotlight over by 4 turned on now also. They must be doing something
by lillymunster 11/5/2011 2:48:11 PM

@dicko They have a big spotlight over by or on top of the common pool. There is sometimes a flurry of activity at night. They will turn it on and there is usually steam or smoke. There is never anything corresponding in the next plant status report from TEPCO. Nobody knows exactly what is going on.
by lillymunster 11/5/2011 3:00:01 PM

@dicko Thanks for pointing it out. I don't watch the cameras as much as I used to and that may be the case with others so if someone does see something it is good to let people know so it doesn't get missed.
