Japan declares 'nuclear emergency' after quake - PART 2

a reply to: TheWetCoast


Actually the evidence doesn't support on going fission.... the temperature is too low. I suspect there may be too much groundwater for there to be anymore fission.... unless the groundwater is somehow removed allowing the coriums to heat to the point where fission is possible...(cough cough ice wall).

Building an ice wall to change the flow of groundwater without knowing the actual location of the melted cores is pure craziness. Personally, and I know I could be wrong, but I strongly suspect that the massive amount of groundwater flow is beneficial in keeping what is left of the cores cool. Tepco has already admitted that the containment vessels are leaking water... it really makes no sense to remove the groundwater at this point.

It is much much more likely that the cores would heat back up hot enough to produce steam, which is a bad enough idea in itself, without actual fission.

a reply to: RickinVa Uranium-238/235 and Plutonium-239 etc. go though the process of nuclear decay; that means fission. The core of Reactor #3 WILL GO CRITICAL eventually. If the only isotope involved was Uranium-238, the process would take at least a million years. With Uranium-235 and Plutonium-239 involved the Corium could become unstable at any moment.

The ice wall "solution" seems to be a total bust:

Thanks for posting it. 250,000 tons of bagged, radioactive dirt laying around and Tepco has no time to answer questions. Yes, I'm sure they're full time busy covering their butts, er I mean solving the problems. *sigh*

Does anyone know why they can't recycle the water being used to cool it instead of continually contaminating fresh water?

Yes.

Way back in the original thread we discussed surface boiling and galvanic transfer. Due to the excellent collective nature of the collaboration it became apparent that, with insufficient cooling, tepco's game of 'cooling by whack-a-mole' caused the #5 and 6 reactor pools to become contaminated ( as evidenced by cesium being found in the drains evidencing uncontrolled criticalities ( fission)) . This led to the prediction ( by yours truly ) over two years ago of EXACTLY the condition we see today; "boy howdy ...!!!..."surprise" leaking" .

So , in short, they cannot 're-use' water now ( the same as in the beginning, meaning little has really changed ) because it becomes too 'hot' ( radio active ) because each pass of re-circulation liberates more hot particles ( which remain in solution where they can and will create criticalities ( uncontrolled fission ) just like when Tepco killed three unskilled or possibly untrained employees by allowing them to mix liquid uranium solutions and thus be exposed to a purely aqueous criticality that burned and killed them ...well before the accident)

Thus....given their mindset ( cover thy ass and lie as a rule ) they HAVE TO HAVE LEAKS because they cannot AFFORD to keep 'warehousing' (storing) all the liquid waste.

This is not the first time I have said this here.

It also CLEARLY illustrates that uncontrolled criticalies are STILL occurring at fuku...

as an aside; the core of three is LONG gone, a melt mass from it's it's broken ( and mostly EMPTY) storage pool is almost certainly in the remains of the torus and CV

wow

corium is an easily understood process if one considers ; the square to cube relation , the fact that surface area ( not volume ) defines both chemical reactions ( contact time) and heat dissipation ( or retention ) and water ( or other ) immersion ( slow neutrons = fission ( i.e. water present) or fast neutrons = no fission ( no mediator ( normally water) )

"corium" is much less likely to "become unstable" ( because it is finding a 'natural balance' to heat produced as to heat lost ( in the square vs cube relation) ) than "spent", WASTE rods.

Ask anyone whom lives near the Ural mountains what happens to "spent" waste rods when they get exposed to air .

a reply to: Silverlok The Corium from reactor #3 should be considered to be VERY unstable. When Plutonium-239 absorbs neutrons it can create Plutonium-240(which is considered to be unstable). I guess we will have to just wait and see what happens.

they are covering something up:

TEPCO to transfer unused fuel rods to new location

The operator of the crippled Fukushima Daiichi plant will alter its plan to transfer the fuel rods from the number 4 damaged reactor building. Some fuel rods will be stored at a new location in the plant.

Tokyo Electric Power Company says it will apply for approval for the change of plan to the Nuclear Regulation Authority shortly.

As part of the decommissioning efforts of the reactor, work has been underway since last November at the damaged reactor building to transfer more than 1,500 assemblies of spent and unused fuel rods from its pool to a common fuel storage pool in the compound.

In the run-up to the transfer, TEPCO planned to make space in the common pool by removing fuel rods which had already been stored there. It decided to place them in casks.

But the utility says delayed confirmation of the casks' safety has prevented it from preparing the rods in time for the planned transfer.

The company says that with the common pool remaining partially occupied, it will be obliged to transfer and store part of the fuel rods from the number 4 building in the number 6 reactor building instead. Specifically, it will transfer the 180 assemblies of unused fuel rods that are emitting comparatively lower levels of radiation.

The number 6 reactor was offline at the time of the 2011 disaster and escaped serious damage.

TEPCO officials say they hope to begin the transfer to the number 6 building in November. They plan to remove all rods from the number 4 building by the end of this year as scheduled.

They have transferred 1078 out of 1533 fuel assemblies out of Unit 4. They probably kept the most difficult ones (broken, burned, melted) till the end.

17,000 Bq/Kg of Cs-134/137 from soil of a public drinking fountain in Yaita city Tochigi Posted by Mochizuki on June 19th, 2014 · 10 Comments Share on facebookShare on twitterShare on emailShare on printMore Sharing Services A Japanese citizen posted on Twitter his radiation analysis result to measure 17,000 Bq/Kg of Cesium-134/137. The sampling date was 6/17/2014. It was soil taken from a public drinking fountain of Happo-gahara parking lot (The picture and map are attached below) in Yaita city Tochigi. Cs-134 density was 4,221 Bq/Kg, Cs-137 density was 12,353 Bq/Kg (16,574 Bq/Kg in total). It is not clear if the soil could have been mixed with water, but still extremely high level of radioactive material is found in Kanto area.

Also, some of the member doctors have already evacuated themselves to be absent from the meeting. 9:34 6/17/2014 “A pediatrician that I always consult said that it was reported in the recent academic meeting that nursery school children have nosebleed unusually increasingly in Tokyo. Some doctors made eye signals at each other to stay silent. Some other doctors spat out “Recent children are weak.”. The rest of the doctors didn’t attend the meeting, which means, they have already left here.”

WHY should corium (as opposed to poolium)(at three, if there is any , because that core blew to pieces ) be more unstable than any other corium that exhibits no instability what-so-ever; once rods become "corium" thermodynamics and radioactive decay and excitement are very well defined.

perhaps you can define what you mean by "instability" ( as any radioactive material is , fissioning or not , inherently unstable,) unless the periodic table and hundreds of years of scientific observation have missed something that you can apparently provide that defines or constitutes stability.

confusing elemental'chemical stability with situational stability is why so few architects are also engineers

Sorry ive been watching the Crane,, and cable



things are getting shaky ,, little farther North,,,well not that far,, geophisicaly.

a reply to: Silverlok
The SFP of Reactor #3 blew to pieces but the core did not. The core of Reactor #3 did melt down 100% and is somewhere underneath the building. I took the time to figure out what the MOX fuel used in Reactor #3 was made of; once you know WHAT that core of Reactor #3 was made of you can understand what it will do.

a reply to: TheWetCoast

"Reactor #3 was made of" was found spread all over fucushima,, there are analysis of the Atomic sig. that match's.
and there are pictures,, of one such area/site,,, its out there,,already,,

as well as pieces as u state,,,and when it goes critical it gets really really foggy,,
called heat / moisture = fog.

Kamikaze....

So they drill 25 meters and ground pressure problems start to occur....the frozen wall is to 100 meters deep.

TEPCO: Contamination could spread in deep water

The deep layer of water is about 25 meters below the surface. Water there was found to be contaminated on June 4th, when 4,700 becquerels of tritium per liter were detected in a well near the No. 1 reactor building.

And Delay freezing barrier:

Nuclear body to examine delay in freezing water

Japan's nuclear regulatory body will examine the delay in efforts to prevent radiation-contaminated wastewater from flowing into underground tunnels at the damaged Fukushima Daiichi nuclear power plant.

About 11,000 tons of water used to cool melted-down fuel has leaked out of reactor buildings into underground utility tunnels, from where it is believed to be flowing out to sea.

Tokyo Electric Power Company began pouring a chemical solution into the joints between the reactor buildings and the tunnels in April. This process is designed to freeze the wastewater and create a wall of ice to prevent more water from coming in. But the water has not fully frozen as planned.

At a meeting of the Nuclear Regulation Authority on Wednesday, Commissioner Toyoshi Fuketa said work to stop water flowing into the tunnels, the part of the problem with the highest risk, has been slow. He said until this work succeeds, there can be no discussions on a larger plan to freeze soil around the reactor buildings.

Chairman Shunichi Tanaka said the work needs to be monitored and guided, to ease public concern.

The authority plans to convene a meeting of experts to study why the water hasn't frozen as planned, and how to proceed.

Hey everyone - I suspect posting has stalled because there's (seemingly) nowhere to go but down with this mega-catastrophe. Here's some *breathe deep* updates from Fukushima-Diary...

fukushima-diary.com...

Nuclear Expert “Fukushima plant is now like a swamp of radioactive material due to the contaminated water”

710,000 Bq/Kg of Cesium-134/137 detected from “iron sand” gathered by neodymium magnets

Google trend shows “Joint hurts” is searched increasingly since 2011 in Japan / Sr-90 accumulates in bone

Cesium-134/137 detected from the body of 20 citizens in Kashiwa city Chiba / 11 are under 6 years old

I've also seen reports of Fukushima tomatoes selling for a fraction of tomatoes from other regions, reports of plants shooting through the bags of contaminated soil that was bagged and left in piles and reports of thyroid problems in young children highly under-reported. Anyone have any good news about Fukushima?
