We have been thoroughly investigating the hidden danger which lies with the reactor 4.
And we have discovered a new fact.

When it reached the latter part of 700 degree C, what has happened to the fuel rod?
This is the new hidden danger of the fuel rods.
During the heat test, a change has occurred when the temperature of the fuel rod reached latter part of 700 degree C.
The fuel cladding has ruptured now.
When it ruptured, the temperature was at 780 degree C.
You can see the rod is red hot.
The fuel cladding is supposed to contain the radioactive fuels but it has expanded and a hole has appeared.
This is the ruptured hole after it has been heated.
In reality, other than meltdown, there was another way in which the fuel rods could be damaged.
Furthermore, when fuel rods are subjected to a rapid temperature change, not only it creates holes, the whole fuel rod could disintegrate completely.
When the temperature rises, the strength of the fuel cladding, which holds the fuel pellets, is reduced.
At the same time, internal pressure rises so generally the fuel cladding ruptures when the temperature reaches over 700 degree C.
According to the previous experiment conducted by the JAEA, most of the fuel cladding ruptured when the temperature reached between 700 to 900 degree C.
If the spent fuel pool or the reactor 4 building collapses for whatever the reasons, and if spent fuel rods pile up in one place, cooling becomes impossible, which means that even before meltdown occurs, it is possible that the fuel rods could rupture, as a result, there is a possibility that gradual release of the radioactive materials could occur.
What would TEPCO says?
Q: We’ve obtained an experiment result which shows that the fuel rods rupture above 700 degree C.
Did you know about this?
TEPCO: Did you say rupture?
Q: Yes.
TEPCO: I have no knowledge about it.
TEPCO: I think it is possible that cracks or rupture could occur due to weakened fuel rods.

Didn't Arnie do a demo about a year ago showing how the fuel case shatters easily when heated…..they are always rupturing and that is one reason reators have to have emergency shut down for unexplained power generation….the fuel fissions all along the ruptures…it's a frequent occurence in the industry.

The temperature here (780*C) appears to be lower than Gundersen's:
"When you see hydrogen explosions, that means that the outside of the fuel has gone past 1000 degrees Celsius and the inside of the fuel is well over 2000 degrees Celsius. At that point the fuel gets brittle, and the zirconium coating burns, giving off hydrogen gas."

The demo I saw, Arnie used a blow torch for a minute or two to heat the zirconium…not sure how hot it got but his point was to demonstrate how fragile and at what a low point the ziroconium became brittle and shattered with ease. His demo didn't take 10 minutes…so I truly believe the temperature is low for the incapacity of the ziroconium to remain a protector of the fuel.

The JAEA tests that you are referring to were most likely tests simulating large break loss-of-coolant accidents (LB LOCA). It is true that in a LB LOCA the fuel rod cladding would rupture when it locally reached about 780 C (1436 F) or lower; and once the fuel rod cladding locally reached about 1000 C (1832 F) it would start to "burn" (rapidly oxidize) in steam. Please keep in mind this is for a LB LOCA. I am not discussing a spent fuel accident.
But in the cores of Fukushima Units 1, 2, and 3, it is likely that the fuel rod cladding started to locally "burn" (rapidly oxidize) once it locally reached about 1000 C (1832 F), causing the temperature of the fuel rod cladding to locally rapidly increase up to the point at which zirconium melts–just above 1815 C (3300 F)–within a few minutes. This what leads to a meltdown.
Also, in the Fukushima accident–assuming that there were complete meltdowns–more than 3000 kilograms of hydrogen could have been produced per unit (Units 1, 2, and 3).
Here is a link with some information discussing some of these safety issues (with a photo of a "burnt" (heavily oxidized) zirconium fuel rod bundle from a LB LOCA test conducted by Westinghouse around 1969):

Does anybody have an english translation/subtitled version of this video? What are sites are you guys checking daily to see if SFP #4 is still standing?
There's many theorists out there saying nothing is being done because TPTB are calling for population reduction anyways …. if this is true why is it that TPTB don't seem to realize that by irradiating the planet they are destroying the the world they seek to hoard for themselves? durrrrp.

Maybe they are throwing a little radiation out there before they send out the huge amount of radioactive material that has a 30 day half life…where they will run down their holes and tunnels and stay till the rest of us are all exterminated like those foggers for the cockroaches….whoever then survives will crawl out of their holes then blame the whole thing on fukushima…at which point they will discover there really was no fukushima it was all smoke and mirrors…just sayin!

There's a video that a lot of Nuke-lovers show that has a piece of zircalloy cladding under a blow torch. That's their proof that they won't burn.
Now it seems that they don't actually have to burn and can still be catastrophically damaged. Who woulda guessed?

Holes in cladding, from the Wikipedis article on Zirconium: "One disadvantage of zirconium alloys is their reactivity toward water at high temperatures leading to the formation of hydrogen gas and to the accelerated degradation of the fuel rod cladding:
Zr + 2 H2O → ZrO2 + 2 H2
This exothermic reaction is very slow below 100 °C, but at temperature above 900 °C the reaction is rapid. Most metals undergo similar reactions. The redox reaction is relevant to the instability of fuel assemblies at high temperatures."
http://en.wikipedia.org/wiki/Zirconium
Also, cesium + zirconium = BANG!
What happens when cesium touches water even at room temperature? Take a look:

This lab video is the smoking gun that will end the nuclear industry. This cannot be. Kept a secret. Water is definitely not to be used anywhere near cesium. Boiling WATER Reactors are a very bad idea, one gigantic design flaw.

These are the allowable stresses for zirconium as the temperature changes. These allowables are from an old copy of B31.3. You can see how the allowable stresses fall off as temperature increases. The allowable stress is almost nothing at 700 deg F. A couple hundred degrees and there would be no allowable stress in the material. Nothing to hold the pressure. Nothing to hold its own weight. Nothing. This is no where close to the temperature TEPCO is talking about. I can not say this enough. The material does not have to melt to cause a failure. The material will fail long before it melts.

Typical TEPCO response. Probably a translation issue, but will TEPCO keep saying "we didn't know about this" as a means of denial and not accepting responsibility?
So what's the actual status of all the spent fuel in the SFP's? And what about places like Ft. Calhoun (are their spent rods in dry cask storage) or any of the other facilities housing SFP's which lose cooling during natural disasters (fires, earthquakes, hurricanes)?

I have long suspected some of the "flashing" we have seen in the sky, as the cranes worked (but were being photoshoped) were fuel rods being moved, and the flash was the heated zirconium reacting to air… looked like a flash from a camera.. another example of (hu)man not being nearly as smart as he thinks he is..and they are moving ahead rapidly with generation IV tech.. absurd and outrageous, and unable to do so without a tremendous amount of tax dollars from willing governments..

here's another fact; without knowing where the melted 180 tons of corium fuel from #'s 1,2,3, is, you cannot make valid decisions for spf#4 "stabilization" and if they know where they are and the status quo reflects that,,,or if they dont know where they are and the status quo reflects that.

These beta flares we are seeing are from what and where?.
Are they from the corium interactions or and from the disintegration
of fuel rods in the SFP's
" if spent fuel rods pile up in one place, cooling becomes impossible, which means that even before meltdown occurs, it is possible that the fuel rods could rupture, as a result, there is a possibility that gradual release of the radioactive materials could occur."
do we really know the state of the fuel rods in all the SFP's at Fukushima?
we've been told SFP4 lost it water and then was filled up again?
what happened in that space of time? do we have a fuel rod puddle at the bottom that
is releasing lots of free nuetron's thus causing beta flashes?
how deadly is this ongoing fall out from the beta flashes?

I have questions.
What caused the hydrogen explosion in Unit #4? I have heard from one source it was caused from hydrogen in Unit#3, but the Unit #4 building is more damaged. So that is doubtful.
There were fires in the #4 fuel pool so if the hydrogen explosion was from the fuel in Unit #4 fuel pool then how has that affected the fuel pools integrity?
What has happened in the fuel pool and what is the condition of the fuel bundles there? If there was enough temperature increase and loss of water, then the fuel bundles could be greatly damaged.
At TMI they first thought there was little damage to the fuel because the top of the fuel bundles seemed to be in good shape. After they started work they realized that the most damage was lower in the core.
The condition of the fuel bundles matters because it will change any kind of work to remove them, but it also brings up the question of the integrity of the inside of the fuel pool. I do not believe that fuel pools are not meant to withstand the same temperatures as the reactor vessel.
They have checked the levelness of the pool, and the outside shape of the building, but that is neither the scientific or nuclear way of verifying the integrity of anything. TEPCO would be better off just shutting up.

"I estimate that it will only take a short time to empty the spent fuel pool
should the pipes get damaged and cause leak."
"there is not enough support"
"If water drains, I am not certain how long it will take
before the fuel rods start to melt"
….release of radioactive materials and radiation wold be so great

Two years ago, Mark Leyse, son of a former GE researcher, and the New England Coalition on Nuclear Pollution, gave the US Nuclear Regulatory Commission a report from GE research done in the late 1970s that showed zircaloy cladding would begin to strip oxygen atoms out of steam at above 1852 degrees F., oxidizing, and rising in temperature to 3000 F. in about a minute. The NRC guidelines said zircaloy was good to 2250 degrees F. The research report included photographs of fuel rods that had been destroyed in this way.
The response to this was that the NRC would think about whether anything had to be done about this, a process that lasts around three years. The next step would normally be to spend a few years figuring out what to do. Since the temperatures involved are well above any a nuclear plant would normally encounter, the final step would probably be to tell everyone to take extraordinary action at a somewhat lower themperature than previously thought necessary.
This article tells me, once more, there is a good deal more to this sad saga the NRC really doesn't know about.
But don't worry, some time after the Germans close their last nuclear plant, the NRC will understand something is wrong, and something should be done. And it will only take until about 2030 to figure out the plants they relicensed to go to 2032 were dangerous.
I just realized, that is optimistic. It assumes no meltdown in the meantime.

@GH, I believe this is called a pyrophoric reaction. Couldn't find a source that states at what temperature the zircalloy starts to strip oxygen out of H2O, but when it statrts it just gets hotter. The 'byproduct' apart from more heat and more damage to rods and assemblies, is hydrogen…x2 molecules for every one of oxygen which is burning.
Result = high concentrations of hydrogen = plant shattering explosions in Daiichi Units 1-4. Assume then pyrophoric reactions have occurred at least once, in all of them…are there any more that you dont want us to kow about TEPKILL?
