Japan’s ‘Great Tohoku’ Quakes Have Recurred, Data Show
[link to www.bloomberg.com]

[snip]

The “Great Tohoku Earthquake” that shook Japan, unleashed a tsunami and killed 20,000 people last year wasn’t as unusual as geologists first supposed, according to new geological data collected near the fault lines.

Earthquakes like the March 11, 2011, temblor have probably occurred at least three other times in history, according to German, Swiss and Japanese scientists who drilled into sediment 7,000 meters (22,967 feet) beneath the sea. The discovery will help planners measure the risk of such events recurring, said Michael Strasser, a Swiss scientist who led a research expedition to the quake zone this month.

EGU2012: tracking Fukushima’s radioactive dust
[link to environmentalresearchweb.org]

[snip]

After the first problems at the plant on March 11th, the potential gradient measurements at Kakioka dropped by an order of magnitude; ionising radiation increases atmospheric electrical conductivity and decreases potential gradient.

The potential gradient also dropped on March 14th and March 20th. Yamauchi believes the March 14th drop was due to contamination by surface winds, which left radioactive fallout suspended near the Earth’s surface. This is potentially a health risk, especially for children as they breathe closer to the ground.

The March 20th drop was probably down to transport by a relatively low-altitude wind followed by rain, which caused the dust to settle on the ground.

Pressure builds for decommissioning of Tsuruga nuclear plant after fault zone report
[link to mainichi.jp]

[snip]

NISA is the first among government bodies to have pointed out the possibility of the fracture zone beneath the reactors moving in tandem with an active fault nearby. Civic groups and other parties who have urged the government to conduct thorough research on the nuclear power plant run by Japan Atomic Power Co. are calling for the decommissioning of the power station, saying, "It's impossible to take measures (against the possible movement of the faults)." Some nuclear experts have also pointed out the danger posed by the faults.

(UPDATED) Ashes from Sewer Sludge with 16,670 Bq/kg Cesium Dumped in the Final Disposal Site in Kiryu City, Gunma Prefecture

Kiryu City's assemblyman Hidenori Nishimaki and Assemblywoman Yuki Niwayama visited the final disposal site for sewer sludge and took some pictures. The site is maintained by the city's water department.

--Snip from bottom of article--
N: That doesn't count as you being at a loss. The neighbors don't want it here. Return to TEPCO.

O: Uh, that would be a bit difficult...

N: A bit difficult? Lost property should be returned to the owner. [TEPCO's Chairman] Katsumata seems to have a huge mansion. Return it.

O: We don't know.

N: If 8000 becquerels/kg is safe, take everything below 8,000 becquerels/kg to people who say it is safe. For example, your own water processing plant, City Hall, Mayor Kameyama's house. Take it there, if it's safe.

O: Ummm.

N: I am not kidding.

Pretty funny.

Remember tepco saying that material[substances] not on tepco property didn't belong to tepco?

That's exactly what I thought of when I read this. Did you look at the pics? The ashes are covered by a blue tarp held down by sandbags.

@ Southern OR,

what else they can do?

I think many People here do not understand
the scale of this F'Shima-Disaster as well as the
Tsunami-Catastrophe!

When someone pointing a Gun on you or your Baby
your possibilities get very limited!

Work on leakage-prevention wall at Fukushima plant fully in progress
The operator of the crippled Fukushima Daiichi nuclear power plant said Wednesday that work is now fully in progress to build a wall along the Pacific coast, where the nuclear complex is located, to reduce the risks of further contaminating the sea with radioactive substances.

The wall is intended to prevent highly radioactive water accumulating in the plant's reactor turbine buildings from leaking out into the sea by getting mixed with groundwater, although Tokyo Electric Power Co. believes that such an incident is unlikely to happen.

Thread: 60% VOTES THE FELON OUT OF OFFICE..WAKE UP AMERICA

The Solution
Generally speaking, most Radiation cannot escape into the atmosphere if it is covered by water. Honshu, Japan is an island and the Pacific Ocean is conveniently located nearby.

Subsidence charges from multiple nuclear weapons buried by drilling rigs 500 ft (152.4 meters) below and inland of the string of six reactors must be engineered to slide the reactors into the sea. This method works best if there is igneous or volcanic rock behind the subsidence charges, to “bounce” the blast and pressure wave from and “push” the trashed reactors area of the beachfront into the sea.

Specially equipped submarines can then pick up the pieces of reactor cores from under water. The surface of the ocean blocks the escape of radiation. The submarines must work fast to limit killing more of the Earth’s Oceans.

THE TWO WITNESSES THEY STATED IN THE BIBLE .FIRST ONE I TOLD ABOUT WAS IN MAY 16-2008.THYE SECOND EXPLODED THE PLANT.BIBLE VERIFIES MY STORY.
IT CAME AT A TIME OF PARTYING,XMAS 45
SEVENTY YEARS LATER WE SEEN IT RISE TO HEAVEN.
ANY QUESTIONS? I WAS SENT TO REVEAL ALL

WRONG ,WE PUT THE RODS DOWN THE VOLCANO ALSO CLOSE BY AND BURN UP THE RADIATION NATURALLY

I did. Not a great situation.
Burning any radioactive material is stupid.
The place is already a wasteland.
Put the radioactive debris inside the dead zone, same with any other material that is radioactive.
What will it harm that isn't harmed already?
Why burn it, creating concentrated contamination, that still must be handled?
And why store it in the open, next to a school?

Passing the buck between regional and national gov't is a tactic that will only work for so long.
The assemblywoman was not happy....

hey crew, what was the link?

The problem arises when trying to move the fuel assemblies, which are damaged, from the SFPs. They must be isolated and shielded.

And the reactor cores, 1500 tons or so of 2000-5000F molten radioactive death, are immoveable, even if they were accessible.

And, no one is quite sure exactly where they are...

I would say they are somewhere underneath the reactor vessels, if gravity is still in effect in japan.

Nothing can get near those puppies...

~

the two things needed to get the rods out are humans and robots.... neither can get near it.....

if they throw concrete and boron at it, well a minor fix... they can't get anything onto SFP 4, because it would topple over and then ELE......

the reason the media is not covering this is because this is true, and they don't know what to do, as this has never occured before... is what we keep trying to tell everyone...

there is a solution to everything.... but what?

The learning curve is way behind the situation...

The situation is known, for the most part.
The solution is unknown, and after the fact is the wrong way to develop a strategy and technology to deal with the situation effectively.

Ultimately, this is the fault of the industry for being so short-sighted and arrogant as to believe this couldn't happen, and for failing to fabricate a viable plan in case it ever did.

And a very costly fail it will be..

debris map of spent fuel pool 4, and heat overlay...

The temporary "solution" for SFP 4 might be to support it and shore it up by filling in with concrete below and on the sides, rather than the "scaffolding" they say they have in place now. The ELE disaster could be caused by a simple leak in the concrete as it is now.

If filling the lower area with concrete causes problems for pumps or pipes, perhaps some pipes and pumping could be rigged above.

No?

if after more than 12 months, we have heard no sollutions from the IAEA, TEPCO, Universities etc etc etc.... then i think we are truly screwed.... even the US nuke fleet headed off.... they have heaps of nuke engineers working for them......

@ ehecatl,

the SFP is more stable than many People here think,
in theory it is even safer than before!

There are now support Pillars
and Concrete Fillings of the smaller Rooms
on the Side!

Hope you're right.


Hear that folks? We've got to put our hope in what Atom-boy says or all is lost.....

I'm goin to sleep now, and wishing myself good dreams. You got to stick with the point of view of the spirit or soul to do that.

@ ehecatl,

No, are you crazy?

Fukushima governor apologizes for deletion of data about predicted spread of radiation
[link to mainichi.jp]

[snip]

The Fukushima Prefectural Government reprimanded its officials, including Hiroyuki Aratake, then deputy chief of the Fukushima Disaster Emergency Center, for their improper supervision. It also issued a strong warning to two prefectural government employees who had actually deleted the data from the System for Prediction of Environmental Emergency Dose Information, known as SPEEDI, which predicts the dispersion of radioactive materials.

Well... don't be TOO hard on them.... sheesh.

Restart of Tsuruga reactor difficult due to faults
Japan's Nuclear Safety Commission says an idling reactor along the Sea of Japan coast will not be allowed to restart if a fault running directly underneath proves active.

The operator of the Tsuruga plant in Fukui Prefecture was ordered earlier by the Nuclear and Industrial Safety Agency to check the fault, which runs just below the number 2 reactor.

Operator, Japan Atomic Power Company, has taken the reactor offline for regular safety checks.

Govt. briefs on restart to people near Ohi plant
People living near the Ohi nuclear plant in central Japan are wrestling with whether to sign off on a plan to restart two of the facility's four reactors. The plant could be the first unit to resume operation in the year since an earthquake and tsunami triggered an accident at the Fukushima Daiichi plant.

Local residents brought various concerns to a public meeting to hear a government briefing Thursday on why it wants to restart the reactors.

Some 550 people attended the gathering that was open only to local residents. Activists opposed to the resumption of the reactors held a rally outside the venue.

Cesium contaminated fish found in Tone river
Radioactive cesium exceeding the new legal limit has been found in fish in the Tone River, which passes north of Tokyo. Authorities have taken measures to stop the shipment of fish caught in the river.

Chiba prefectural officials say a silver crucian carp caught in the river contained 110 becquerels of radioactive cesium per kilogram. The new limit is 100 becquerels per kilogram.
