Read nhk who begins to admit a reality of Chinese syndrome in progress (65cm ???? but they can not know in reality, apart from informing on the low thicknesses of cement in the construction of the reactor):

TEPCO: Melted fuel ate into containment vessel

The operator of the damaged Fukushima Daiichi nuclear power plant has announced the results of an analysis of the production of 1 unit.

The Tokyo Electric Power Company, or TEPCO, and several research institutes made public their analyzes of the fuel rods at 3 of the plant's units at a government-sponsored study meeting on Wednesday. The analyzes were based on temperatures, amounts of cooling water and other data.

TEPCO said that in the worst case, all fuel rods in the plant 1 number of reactor may have melted and dropped through its bottom into a containment vessel. The bottom of the vessel is covered with a steel plate.

The utility said the fuel may have been eroded to the depth of 65 centimeters. The thinnest part of the section is only 37 centimeters thick.

TEPCO also said that 57 percent of the fuel in the plant's 2 number and 63 number may have melted, and that some of the melting fuel may have fallen through the reactor vessels.

Fukushima plant chief to go on sick leave

The head of the Fukushima Daiichi nuclear power plant is stepping down for health reasons.

Masao Yoshida of Tokyo Electric Power Company has been in charge of dealing with the situation at the earthquake and tsunami damaged.

The utility says Yoshida, who will be replaced on Thursday, is resigning in a hospital. The company says it can not disclose its situation.

In a statement issued on Monday, Yoshida expressed regret for leaving the plant at a crucial time and apologized to all the people involved. He said that he has gone through a health check-up.

Yoshida spoke to reporters on November 13th when the accident occurred. He said that he had to wait several times during the first week of the crisis.

He added that when he saw the hydrogen explosions at the 1 Number and 3 reactors, and when his team was unable to pump into the 2 reactor, he thought it was the end.

The utility says Takeshi Takahashi, who is a manager at TEPCO headquarters, will succeed Yoshida.

I found a video "C'est pas Sorcier"
(Dys) operation of a nuclear power station

where Jammy simply explains, but precisely the security and risks of an atomic power plant, including hydrogen recombiners, which are intended to extract H2 from the enclosure and expel H2O form outside.

The conclusion of the video is particularly highlighted by the events coming from the country of the Rising Sun ... I let you listen.

Description: Nuclear energy, explained by balls;)

By or for? : Cheesy: : Cheesy: One wonders who is the ball ...
Also I do not understand the intro editing video either ...

The description is completely rotten, The ball is the guy who wrote that.

Because this report is excelently done. Jammy Gourmaud is very good on this show. The models are nice and the speech is accurate and balanced.

If you want to create a subject for your idea, I let you do 8)

Jammy is always excellent!

I already bought the integral (truck + trailer) for the son ... for later (in anticipation if it does not exist in a few years ...)!

In fact, C not sorcerer is even frustrating: I think I have never found 1 wrong with their explanations! : Mrgreen: : Mrgreen: (and yet you know that I am a pro Kritiker!)

Sometimes there is rarely something to complain about, but it is clearly the fault of the French scientists who advised them, instead of foreigners.

Levels of external contamination, not the unknown internal one, much more difficult to measure, if not impossible if locally radioactive dust !!
Jancovici will say that it is not documented and therefore nothing !!

They still believe in being able to decontaminate !!

Fukushima residents' radiation exposure revealed

Health checkups show that some Fukushima residents are exposed to 15 millisieverts of radiation in the first 4 months after the nuclear disaster.

The government has set a target for one millisievert per year as a safe exposure level.

Fukushima Prefecture has been testing all 2 million residents following the Fukushima Daiichi nuclear plant in March.

The authorities announced the Estimated external exposure levels 1,700 people living in 3 municipalities, including Namie Town and Iitate Village.
These areas have been designated as evacuation zones after the accident.

The results show residents, excluding those working at the Daiichi plant, were exposed to a maximum of 15 millisieverts of radiation during the first 4 months after the accident. About 10 people were exposed to more than 10 millisieverts.

These figures have been made public.

Radiation levels of over 1,100 people, or two-thirds of the residents in the 3 municipalities, were less than the annual permissible limit of one millisievert.

98 percent of those tested to be exposed to less than 5 millisieverts.

Some residents working at the nuclear plant have been exposed to 30 millisieverts.

Former Fukushima plant chief has esophageal cancer

Tokyo Electric Power Company says the head of the disaster-stricken Fukushima nuclear power plant has been diagnosed with esophageal cancer. The company quotes his doctor as saying that he is very unlikely to be exposed.

Masao Yoshida had the efforts to stabilize the plant after the severe accident of the earthquake and tsunami. The company connects him to his post last week, one week after he was admitted to hospital.

On Monday last week, the firm announced its hospitalization but did not reveal its disease or how much it had been exposed to the disease. The company cited the 56-year-old train plant's need for privacy.

On Friday, Tokyo Electric announced that it had obtained Yoshida's consent to disclose that it has esophageal cancer.

It has been exposed to accumulated radiation doses of about 70 millisieverts. The upper limit for plant workers is 100 millisieverts.

Quoting experts' views, the utility said it takes at least a few years to develop this type of cancer and the chances are slim that Yoshida's disease is linked to its exposure to radioactive fallout from the nuclear accident.

Yoshida reportedly visited the Fukushima plant on Friday.

Full decontamination to start in Fukushima in Mar.

Japan's Environment Ministry says it will take place in Fukushima Prefecture until late March.

A law requires the next day to be decontaminated with high radiation levels. The Daiichi nuclear power plant. The government is now conducting a model project to seek effective ways to clean up the contaminated areas.

The Environment Ministry said it would start decontamination work for these areas in January or later. However, it is revealed on Sunday that full decontamination efforts for houses and farmland will begin in late March.

The ministry said it will start decontaminating infrastructure, including roads and electricity supply systems, in late January.

The ministry said it would take time to get permission to evacuate to decontaminate their homes and agricultural land. It also cited the difficulty of securing temporary storage sites for topsoil removed during decontamination work.

Regarding areas with annual radiation far above 20 millisieverts, the ministry said it will only start decontamination after launching a new model project to decide ways to do so and ensure the safety of workers.

The government is legally obligated to endorse the transfer of decontaminated soil by the end of March 2014, except for areas with particularly high radiation levels.

Govt compiles decontamination guidelines

Japan's Environment Ministry has compiled guidelines for the removal of radioactive materials discharged from the Fukushima Daiichi nuclear plant.

The 164-page document with illustrations was made at a meeting of experts on Sunday. It was compiled for residents of cities and municipalities.

The 4-part guidelines cover ways to measure radiation levels and remove radioactive substances. They also show how to collect, deliver and store radiation-tainted soil and other materials.

The decontamination process will be different for buildings, roads, soil and plants.

The guidelines recommend that water volume and pressure for decontaminating buildings should be increased.

It says moss and dead leaves should be manually removed before high-pressure sprays are used to save water.

It adds that it should not be drained but collected in buckets.

The guidelines proposes the use of separate containers for different levels of radiation-contaminated soil. They also give the safe distances from storage of residential areas.

Ministry officials say they hope the guidelines will facilitate the implementation of a plan to build temporary storage facilities.

The Ministry is expected to release the document on Wednesday and explain to the residents of Tohoku and Kanto regions.

Now we are going to say that the tsunami of Japan was an impossible accident:
There was not one, but two tsunamis the 11 march in Japan
http://www.7sur7.be/7s7/fr/2664/Catastr ... apon.dhtml

gold a double or more, vague on the surfaces of the seas and ponds is very usual, for very nonlinear waves (very visible by throwing a simple stone in a pond, because not linear and complex, to film)!

So this statement of very rare and improbable, that two initial waves gather in amplifying, is arch-false and a lie.
It is very usual !!
There have been several waves (as very visible for the late 2004 tsunami in the Indian Ocean), but the finding of scarcity is false:
there were tsunamis as high on Japan, less than a century ago (in 1933 and 1896 see wikipedia) and so it was a tsunami that would happen sooner or later, and not at all improbable.

It's about manipulation, most strong disasters always seem improbable but real (even economic), because one always underestimates oneself, thinking oneself infallible, as for the French nuclear, which sooner or later will have its unforeseeable catastrophe, emptying for centuries a whole region, humans are not infallible in perpetuity !!.

Hello,
I do not know if it was said:
The nukleaire accident of fukushima was easily avoidable.
The jap did not know their plant well, and did not know that it was necessary to manually open the condenser valves.
Condenser that works very well without electricity.
Unforgivable, lamentable

It is true that seen as this, human error is unforgivable.

A translation error on the rican manual and jap zaps a basic manipulation.
At least: no mistake, but misunderstanding ...
