@Alblee Pretty sure they melt together into corium from wikipedia Corium, also called fuel containing material (FCM) or lava-like fuel containing material (LFCM), is a lava-like molten mixture of portions of nuclear reactor core, formed during a nuclear meltdown, the most severe class of a nuclear reactor accident. It consists of nuclear fuel, control rods, structural materials from the affected parts of the reactor, products of their chemical reaction with air, water and steam, and, in case the reactor vessel is breached, molten concrete from the floor of the reactor room. en.wikipedia.org

Different bucket then the reactors ,but same result.

NHK was that not in air from Chernobyl? Not like this case.There is still water here.
by Ralph Unger 4/12/2011 8:52:27 AM

@Ralph Unger so what would be there charicteristis... think some are just floating in ocean, laying in dirt, explosion IMOP put some in to "peas going every where" will they just cool faster, does it depend on what there land on etc...
by fitter 4/12/2011 8:52:42 AM

@Ralph Unger There have been a few reports stating the rods have melted.. Melting means corium.

@NHK Listener any ideal the wall thickness and tensile strenth of the bundle and rod containers

Kan is currently speaking on: www.ustream.tv (Japanese only). Just switched it on, so no details.

@Sinthia Domina thank

@fitter The concrete wall? It is 2 meters thick.
by borrrden 4/12/2011 8:54:52 AM

Thanks, @NHK_Listener. So that means something like this is extremely difficult to stage and control - and study/observe - under lab conditions.

One more: Might there be some polyurethane foaming materials that can be used to spray onto loose fuel material (say, strewn ejecta on the ground around ground zero) that would make the now fuel-particle-garbed-in-foam-that-has-set-some to be more easily picked up with less risk of it breaking apart into smaller pieces, so net effect is easier harvesting of these fragments and quicker clean-up work? Thanks.

Fission is caused by a certain amount of material being in close proximity. That is why they put it into rods, to control how much is close to other amounts. If it is a bunch of pellets at the bottom of a pool, who can say what might happen?
by Ralph Unger 4/12/2011 8:55:09 AM

@fitter Not sure off hand.. They are made by Areva
by NHK Listener 4/12/2011 8:55:14 AM

It could never blow up like an atom bomb, the fuel is not rich enough, it could make a good bit of radioactivity though.
by Ralph Unger 4/12/2011 8:56:46 AM

@borrrden i meant the steel containers, could you translate that title block for me...did see your responnse until ten hours later.....What are we doing with the avatars ...is that u nkl.... be nice to use older folks

@fitter Which steel container? And what title block are you talking about? I'm not catching your meaning....

@Alblee its common to spray the ground for "dust" conditions.... most plants run water truck every day....BUT i bet the reason they spayed the blue/green gunk on the ground was partualy due to rad contamination and would bet they know they have loose pellets they are trying to hold in place
by fitter 4/12/2011 8:59:42 AM

Speaking of the fuel assemblies, they are talked about in part 2 of the documentary that I translated yesterday: www.youtube.com
by borrrden 4/12/2011 9:01:02 AM

There has been no evidence of a major breach in the primary reactors. They are just spraying to stop the dust from getting the air from the releases that happened earlier which made a lot of radioactive dust..
by Ralph Unger 4/12/2011 9:02:07 AM

@NHK Listener great drawing, now ifffff only in US, i spend to much time have to convert,,,,, where do you find all this stuff
by fitter 4/12/2011 9:02:12 AM

@borrrden i could only find that in japanese
by fitter 4/12/2011 9:02:40 AM

@Alblee I suspect they don't want to add anything to the pile of things to store forever. I suspect they will use mechanical separation (robots) to remove the contaminates to long term storage
by NHK Listener 4/12/2011 9:02:56 AM

@fitter Only find what? Point me to it!
by borrrden 4/12/2011 9:03:09 AM

@Ralph Unger but let us not forget the spent flul pools....
by fitter 4/12/2011 9:03:17 AM

Why not? just because there is more fuel there then in the reactors? :-)
by Ralph Unger 4/12/2011 9:04:18 AM

@NHK Listener how do i find the elevation drwing of #1 reator bluiding to show borrrden
by fitter 4/12/2011 9:04:26 AM

@fitter well, it depends upon the type of radiation as to how "radioactive" it is, meaning the energy ie:gamma,beta,alpha. This in turns depends upon the amount of the radioactive particles ie: particulates that have been made radioactive by the fission process. All this talk about the radiation spewing or leaking is just wrong. Radiation is energy, that is much like light, as it travels in waves and particles. It doesn't do anything but emit energy, as it IS energy. It can only travel by particles of radioactive material being moved by an external force such as wind, in water etc. The energy emitted only goes a certain distance, much like the beam of a flashlight, and so it is hard to measure exposure in my opinion unless you have more details. Such as age of the person, method of contamination such as ingestion,inhalation,skin, the source of the contamination, length of time of exposure and the measurement of the radioactivity of the substance encountered. Anything else is just speculation and not good science. So far as height, the inverse square is law is applied...so the farther away the less active the energy, or the dimmer the flashlight beam...if that makes sense. If I am wrong about any of this someone please educate me. The only way it would rise through heat would be in steam or smoke.

@fitter I am a team member of a very large forum. I just ask and I can usually get the answer

Gamma is at 590 uSv at Fukushima, That is not too much. but breathing anything or eating it means that you get a little bit of radioactivity for a very long time. Fallout is always the big problem, not dosage from the source.
by Ralph Unger 4/12/2011 9:09:50 AM

@borrrden if you are still there nhk posted drawing, the bottom right hand conor is the Tilte box, it will say who designed, the year, threse are differnt but it should give the name of the engin/drafter MOST inportant is there are five number that run up the left side look like dates they would usaually be the dates and rev to the drawings,,,,
by fitter 4/12/2011 9:10:56 AM

43 people died at Chernobyl from gamma, some say that 200,000 died from cancer later from the fallout.
by Ralph Unger 4/12/2011 9:11:33 AM

@fitter You'll have to be a bit more specific....NHK has many drawings.... :-S
by borrrden 4/12/2011 9:12:36 AM

@Ralph Unger its like asbetoes exposure, how many are still dying
by fitter 4/12/2011 9:13:16 AM

OH nvm, you mean NHK here...not the news channel
by borrrden 4/12/2011 9:13:25 AM

I can tell you how many, just pay me to tell you the facts you want to hear. Lies, damned lies, and statistics. en.wikipedia.org
