Japan television station FTV reported on the 9.9°C (17.8°F) rise in temperature at the Reactor No. 1 containment vessel on Sept. 26, 2012, translation by Fukushima Diary:
- 55.9℃ at 5AM of 9/24
- 65.8℃ at 5AM of 9/26
[...]
The Fukushima worker, Happy11311 tweeted like this
“Now they are doing the construction to install an alternative thermometer to reactor2, and also investigating inside of PCV of reactor1. Speaking of which, they say they opened a through hole on PCV1. Finally they are going to see inside of PCV1.”
Other gauges in the containment vessel are showing an upward trend beginning near the same time. See the temperatures here

Containment1 has a Corium Exit Tunnel connecting it to Rogue Nuclear Reactor1 located in the bedrock below Unit1. The Corium Exit Tunnel is probably full of water, since TEP.gov continues to inject water into Containment1. I'm going to call this temperature spike a "transient criticality event" until someone with nuclear engineering experience corrects me. As ground water ebbs and flows around the cooling corium lava, moderating the speed of neutrons released by fissioning within the blob of sputtering and sparking corium, transient criticalities will occur when conditions are right from time to time. Nearby water boils, and a steam event will be spotted by the sharp-eyed monitors of video feeds here on ENEnews. Boiling water reconfigures the moderation in the hot pocket of corium, shutting down the fission reaction in the pocket. The water column in the Corium Exit Tunnel eventually conducts this heat to Containment1, where it is picked up as a temperature spike. I would expect the heat to dissipate in the coming days, and the temperature in Containment1 to fall 10 degrees C back to "normal". This sort of transient criticality event will occur because Rogue Nuclear Reactor1 lacks control rods and operators to keep output temperatures constant. Still no plan for locating and "decommissioning" the 3 Rogue Nuclear Reactors at Fuku, TEP.gov?

"COLD SHITDOWN CONDITIONS", eh, omniversling? Actually, Rogue Nuclear Reactors1,2,&3 will achieve cold shutdown someday, but probably centuries from now. A Rogue Nuclear Reactor has no reactor pressure vessel, no control rods, no containment, no secondary containment building, no pressure or temperature guages, no control room, and no operators. Rogue Nuclear Reactors are contained by bedrock, and cooled by ground water, which continues to flow around the 3 Rogue Nuclear Reactors and into the Pacific Ocean. The Pacific Ocean Fishery has already been destroyed. Who wants to eat radioactive seafood? There is no operating manual for Rogue Nuclear Reactors, no plan for controlling the reactions within Rogue Nuclear Reactors, and no plan for "decommissioning" Rogue Nuclear Reactors. Since this is the case, all nuclear power plants must be shut down at least for several years, while The Rogue Nuclear Reactors at Fukushima are studied and the accident is fully understood. This shutdown will allow fixes to be designed for some of the serious design flaws in nuclear power plants that may have contributed to the Fukushima Disaster. Fukushima demonstrates that no nuclear power plant is safe. Since ALL NPPs are proven by the Fukushima Disaster to be unsafe, they all must be shut down. Peace.

The control rods melted down along with the rest of the material inside the reactor, then thoroully admixed with the neclear material. Doing a much better job of preventing induced fission reactions. Not that theywould have occurred after a meltdown, because that would mean that the uranium would have had to stay solid and seperated from the rest of the material and then fall to the bottom of the melt and get close enough to other uranium to produce a chain reaction. Once the stuff melts it can't happen, it gets mixed with neutron absorbing material which prevent fission chains from occuring. Then natural decay becomes less and less and so the heat produced becomes less, IE cvooler and also safer over time. A reactor in one place getting hit by double natural occurence does not prove that all nuke reactors are unsafe.

Fury: You live in some kind of dream world, don't you?
Nitrogen injection are on going in all (3) units due to hydrogen production, why it that, is it because the blobs are stable over a year and a half later?
Concrete can't stand vibration so, it is embedded with reinforcing bar (rebar). Not only is sand and rock (the main aggregates in concrete) reacting with the highly radioactive blobs but so is metal of the rebar.
So all the reactors and spent fuel pools and dry cask storage are shielded from releasing tritium, is that what you are saying, not all reactors are dangerous?
Report Comment
Excuse me but concrete is used in construction specifically because it CAN withstand vibration. Cements are available which make concrete stronger than the same weight of steel. I have only seen statements from there that say nitrogen is being used on and off primarily as a precaution as cooling or to clear out other gases not just hydrogen. Nothing i've seen says they are using it continously. Not just cement but the water alone will release hydrogen when it reacts with any metal, called rusting, even when the metal is cold. A precaution is a good thing to have, especially in an enclosed building. And there are still many parts of those buildings which are enclosed.

The liability of nuke power is: it is safe until it is not safe. That is what many rely on. Smiling does not help when nuke reactors pop like corn.

you really think the molten cores could get through the thick mass of basement-concrete, below the reactor ?
I believe that the nuclear fuel lies up there, while the water filters to the underground around through cracks.
It will be there for a century, until Tepco gets money (or one million sacrificing nuclear workers) for a retrieval.

Andres asks: "you really think the molten cores could get through the thick mass of basement-concrete, below the reactor ?"
Yes. Coriums1,2,&3 melted through the concrete and exited Buildings1,2,&3 during March of 2011. Look at the temperature of the corium, even 2,500 F is a low estimate. Look at what happens to concrete, which loses structural integrity at far lower temperatures. Corium cuts right through steel and concrete. Hell, steam and smoke are seen coming from the ground between the buildings almost every day on the webcams. The physics of concrete at high temperatures was much discussed in threads on ENEnews in late March and April of last yer. The concensus here seems to be that coriums have left the buildings.
BTW, although TEP.gov will admit that "melt-through" has occurred, they have not publically admitted that corium has escaped the buildings, and is in the mudrock under the plant.

Oh I don;t know, I think they will eventually get to most of the ground leaks and seal them off, after they get the stuff on top vacuumed up and out of the way. Any ways better for it to be underground than on top. That's where it came from originally.
Report Comment
Fury, your optimism may be warranted, You'd need to explain a plan to "get most of the ground leaks sealed off". It has been discussed here previously.
I have no science training to assess the complexities. I rely on posters here, many with strong relevant training/study and understanding. I also place full confidence in information shared by Arnie Gunderson at http://www.fairewinds.com/. Arnie was a career engineer in the industry. He's been scrupulously careful to 'stick to science'. His assessments and conclusions stay with problem solving but his warnings can only be understood as dire.

Maggie123: As far as the stuff which has already leaked into the ground I believe most of it will not move very far, and that most of the rest of the stuff inside the buildings is cool enough to not dissolve and leak more, provided that they don't have to use seawater (so corrosive) to cool or wash out anything. As far as anything that has leaked into the ground, when they can get close enough to the outside of the buildings, (many different safety factors here), they could drill holes in the ground and pump in compounds which would combine with the nuclear materials and "tie them up". larger molecules and particles move less than large ones. After the primary clean-up IE the buildings removed to the bottom floors or basement, cement could be pumped into the ground setting it up like concrete. And Arnie Gunderson IS the person whom I rely on for the most factual interpretation of what information comees out of Fukushima. However recently he has seemed to be forgetting the basic general construction problem of having TOO many workers on site getting in each others way, and too many engineers with too many conflicting ideas. No matter what you are working with there is a safety limit on how fast something can get done. Any faster and mistakes get made and you have to back up and do over.

Also as far as the leakage through any cracks in the concrete basement and floors those have probably sealed themselves off already by deposition of solids. look at what happens to the pipes that feed water into and out of reactors, boilers and anything else. they get coated with sediment and either have to be replaced or cleaned out, or else they plug up. We are not dealing with a solvent here but dissolved solids that sediment out (deposit) when they come in contact with metals or other solids.
Report Comment
Also one simple way now might be at a distance from the Plants to drill holes and pump latex into the ground to capture anything that MIGHT be traveling away from the plant. Look at what happened at Pantex. The only material that moved outside the immediate area of the Plant was dissolved in various strong solvents NOT water. None of those solvents are in the Fukushima materials.
Report Comment
And you also have to understand that Mr. Gundersons warnings are so dire because he is erring on the side of caution because no one can stay close enough to the buildings long enough to take the measurements needed to determine how much stress those walls and buildings can still stand. Did any of the rebar get broken in the supporting walls? I don't see any indication of this but as far as is known no one knows for certain. However they are still standing in much the same position as they were before, only the wall facades have come loose. They do not look as if they were tied in as part of the structural support. If any rebar had broken in the structure support it should show as a lot of concrete damage in that area, spalling of large amounts of concrete around the breaks, settling of areas above that. I see none of this in the videos shown. I wish that for my own satisfaction I could go over there and just look at some of that but I can't for various reasons an won't because I won't get in the way of people who are doing as well as any one can in this situation.

Radiation can split off the hydrogen in water, besides reacting with concrete.
I've never seen a solid concrete building, bridge or any type of structure, it is always reinforced concrete or it would crumble to the ground.
