Nuclear accident in Japan, a Japanese Chernobyl?

[Obamot]

"it goes away and it comes back ...."

http://www.romandie.com/news/n/Fukushim ... 110811.asp

The operator of the damaged nuclear power plant in Fukushima announced Wednesday that he had started injecting a mixture of water and boric acid into one of the reactors. The fuel could have melted there.

"We cannot rule out the possibility of a localized merger"

If at least by this sentence they meant that the place where the molten fuel is (more than 7 months after the start of this accident) is known precisely ...

But no, obviously, we do not know where the fuel is and we are unable to say in what state it is. As far as controlling it

Difficult to understand the procrastination of Tepco!

Yes we know where the fuel rods are => in the reactor and the compartments provided for this purpose!

How would it be, if the reactor had not melted, that they had not tried to extract the bars from their housing, one after the other? => incomprehensible except that => either they do not have the necessary equipment => or the bars were already in fusion since the successive explosions of the reactors! I opt for the second reason, and we only learn it today because Tepco has always lied to save time while waiting for "the soufflé to come down" ...

Still, if there were only one conclusion: it would always be the same => we absolutely have to get out of nuclear as soon as possible, because we are incapable of controlling this industry and its risk minimization lies, since it is completely powerless once the criticality threshold is reached, which brings its exploitation to a kind of perpetual experimental stage in vivo, uncontrollable and leaving us completely at his mercy.

This is what the nuclear sorcerer's apprentices sold to the municipalities to set up their shit, taking care to hide the truth from us! Since it claimed safety from 1 accident per million years and since we are already in a major accident with reactor fusion, every ten years on average!

And the Belgians are also coming out of nuclear power ...

And in France, it has been two or three times that I hear about in the "mainstream media" (News from France2, newspaper Le Monde, etc.), the risks of supply disruption during the cold peaks this winter: finally, it is widely displayed that France, if it boasts loud and clear that it is globally a net exporter, is clearly importing during winter cold peaks because of our obsession with electric heating / heat pump... We fear that this winter, Germany will not be able to provide us with the equivalent (from memory) of two or three tranches (or central units) that we miss at the end of the day / in the slot around 18 to 21 p.m. .

It's nice to make fun of these "irresponsible people sold to the greens" and ... to depend on them !!!

[dedeleco]

It is complex because Tepco cannot measure anything located under the reactor !!
They do not say for how long precise scientific measurements of the outgoing gases have been carried out, which testify to uncontrolled fission reactions, at a perfectly unknown date, but weak and very slowed down by the injected water !!
Nevertheless they inject borated water for the first time to stop the neutrons which maintain the fission reaction, which they had never done or said before ???
Everything is conditional because impossible to know what is really going on in this inaccessible corium !!
It is still not impossible that it concentrates without water in it to cool it and really farts, which was feared very strongly in Chernobyl by the Russians and involved the work and sacrifice of the Russian liquidators.

TEPCO: Reactor may have gone critical

The operator of the crippled Fukushima Daiichi nuclear power plant says it found in the facility's No.2 reactor radioactive substances that could have resulted from continuous nuclear fission.

The Tokyo Electric Power Company, or TEPCO, said on Wednesday that it detected xenon-133 and xenon-135 in gas taken from the reactor's containment vessel on the previous day. The substances were reportedly in concentrations of 6 to more than 10 parts per million becquerels per cubic centimeter.

Xenon-135 was also detected in gas samples collected on Wednesday.

Radioactive xenon is produced during nuclear fission.
The half-life of xenon-133 is 5 days, and that of xenon-135 is 9 hours.

TEPCO says the findings suggest that nuclear fission may have occurred recently, not just after the March 11th accident, and that a state of criticality could have occurred temporarily in some areas.

TEPCO workers poured a boric acid solution into the reactor on Wednesday to suppress nuclear fission.

The utility says it has not found any significant change in temperature and pressure of the reactor, and that large-scale criticality did not occur.

TEPCO says the reactor's cooling process is continuing and that the firm expects to achieve cold shutdown at the plant this year as planned. But the utility also says it wants to take a close look at the situation of the plant's No.1 and 3 reactors.

Xenon suggests possible nuclear fission

A nuclear energy expert says the presence of xenon in the No. 2 reactor leaves open the possibility that localized and temporary fission could still occur.

Professor Koji Okamoto of the University of Tokyo Graduate School says substances from melted fuel that could undergo fission are probably scattered around, but are unlikely to react.

He says, however, that neutrons from radioactive materials could react with the uranium fuel and other substances.

Okamoto says a self-sustaining chain reaction that creates criticality is unlikely to happen because huge amounts of boric acid have been poured into the reactor.

He adds that these neutrons must be closely monitored to make sure fission does not take place.

The professor also referred to a plan by the government and TEPCO to achieve a state of cold shutdown by the end of the year. He says that if fission reactions are not under control, it would not be a cold shutdown.

Okamoto says TEPCO must locate the melted fuel inside and outside the reactor in order to prevent further reactions.

TEPCO: Radiation levels unchanged

TEPCO says the radiation reading taken on Wednesday near the No.2 reactor at the Fukushima Daiichi nuclear plant was basically unchanged from the day before.

The utility says the reading, taken at a monitoring post about 500 meters northwest of the reactor, stood at 293 microsieverts per hour at 9 AM, up only one microsievert from 24 hours earlier.

It says the radiation level near the compound's west gate, about one kilometer from the No.2 reactor, was also unchanged at 11.2 microsieverts per hour, and that no neutron radiation was detected.

Readings at 8 other monitoring posts on Wednesday were also the same as Tuesday.

Temperature, pressure unchanged in No.2 reactor

TEPCO says temperature and pressure in the No. 2 reactor at the Fukushima Daiichi nuclear power plant is basically unchanged in a 24-hour period between Tuesday and Wednesday.

The company says the temperature at the bottom of the reactor was 76 degrees Celsius as of 5 AM on Wednesday. That was down 1.4 degrees from 24 hours earlier.

The reactor's pressure gauge registered 0.007 megapascals at 5 AM on Wednesday, down one part per thousand from the same time on Tuesday.

Fukushima nuclear disaster: potential evacuation from Tokyo (35 million inhabitants)

Bonjour à tous

I hesitated for a few weeks before sending you the information below, concerning the nuclear disaster of Fukushima in Japan, not wanting to put too many dark notes for the next few years. But, ultimately, I don't think the ostrich head-in-the-sand policy is appropriate, because we have important decisions to make about the future of nuclear power plants, and you can't get away from it.

First, in his latest information video (March 25, 2012), Arnie Gundersen, a world renowned specialist in the field of nuclear power plants, tells us that he went to Japan in February 2012, and took advantage of it. to collect 5 soil samples in Tokyo, at various locations. Upon his return home to the United States, he had them analyzed and all of these samples would be considered nuclear waste in his country, and should be sent to Texas for processing. See

http://www.fairewinds.com/fukushima

Then, it should not be forgotten that a year ago already the Japanese authorities recommended to the population of Tokyo not to use tap water for children, because the threshold of radioactivity was too high. See

http://www.ctv.ca/CTVNews/TopStories/20 ... ns-110323/

To "avoid legal problems" the Japanese government simply increased the radiation thresholds considered safe for people!?!

Now, what you need to know is that this contamination is linked to the reactors of the Fukushima power station, whose fuel rods are contained in closed 15 cm steel enclosures. We now know that the lack of water in 3 of the reactors melted their hearts and produced a lot of hydrogen (by thermal decomposition of the water) which caused the explosions that we know when demolishing buildings, as well than the huge cranes (overhead cranes) on their ceilings, when their function was to remove and move the spent fuel rods to store them in swimming pools (one per reactor).

However, the amount of nuclear fuel in these pools is ten times greater than that of reactors, after more than 30 years of operation of power plants, and all nuclear waste is there, including plutonium, including a few millionths of a gram ingested is enough to give deadly cancer (there are tons)!

What worries Arnie Gundersen and many other world nuclear specialists is precisely what can happen with the fuel stored in swimming pools. The reactor 4 pool, in particular, is in very poor condition and steel pillars had to be installed to prevent it from collapsing (the pools are at the top of the buildings). If an earthquake of magnitude 7 or more occurs, there is a good chance that this pool will collapse or have a major breach that empties its water. And geological experts know that the chances of having such an earthquake are very great over a horizon of a few years. Japan is located on the Pacific Ring of Fire.

If such damage were to happen to this pool or another, the spent fuel rods no longer cooled would ignite, sending far greater quantities of radioactive elements into the environment than we have known. till today. It should not be forgotten that swimming pools are in the open air, and do not have a thick steel enclosure to contain them, as is the case for reactors. And as it would be impossible for all personnel to approach, due to the too intense radioactivity, there is a good chance that the other pools at the Fukushima site will do the same, being left abandoned.

In the event that a single pool empties of its water, and its fuel is projected into the environment, IT SHOULD EVACUATE TOKYO (35 million inhabitants). And if all the pools pass by, it is the whole of Japan that should be evacuated !!!!!!

According to experts, if such an event were to occur, the survival of the human race and many animals is at stake. See

http://www.globalresearch.ca/index.php? ... &aid=30207

Let us hope that the Japanese authorities will have enough humility to ask for the help of the best independent world experts and to remove the management of this disaster from TEPCO (Tokyo Electric Power Corporation) which is in conflict of interest in this case and is trying to cover up the gravity of the situation as much as possible.

So if some of you were still hesitant about the future of the Gentilly 2 nuclear power plant, the only one in Quebec, which supplies less than 2% of our electricity, then we are in surplus for the next 10 years , you should no longer hesitate to ask loudly for its CLOSURE.

Just play the sorcerer's apprentice! Let's quickly return to clean renewable energy.

Bonjour à tous

I have just read another excellent article (dated May 4, 2012) on the problem of the reactor 4 pool at Fukushima, which relates a visit to Japan by the United States senator Ron Wyden (member of the Senate committee on energy and natural resources). In this article, the author mentions that there are 31 reactors similar to those of Fukushima in the United States, with the guard pools of irradiated fuel rods 32 meters (100 feet) in the air. The difference is that many of these American reactors have a much higher amount of spent fuel, or irradiated fuel as it is called, than the pools at Fukushima!

The only protection between these pools and the outside, says the author, is a simple roof like those found at Wall-Mart.

These pools were to be only temporary, until we set up a secure nuclear waste warehouse in the depths of the earth in 1998. But all these projects failed. In addition, in the United States, irradiated fuel rods are left longer in swimming pools than necessary because encapsulation in a vitrified solid material, which should follow the stay in the swimming pool, is very expensive ... hidden costs of the nuclear industry.

It is also mentioned in the article, that if the spent fuel from the reactor 4 pool caught fire due to a lack of water, the cesium 137 emitted would be 10 times greater than the amount emitted during the Chernobyl accident! And if all the pools of Fukushima pass it is 85 times Chernobyl !!! Cesium 137 is an easily evaporated radioactive element which is absorbed by living organisms and is mainly found in the muscles, including the heart. Its half-life being 30 years (half is disintegrated in 30 years), this single element (and there are others) would cause contamination which would last 200 to 300 years ...

For those who have the courage to read the article, and understand why governments don't talk about it, here is the link

The Oï nuclear power plant in Fukui prefecture in Japan should restart soon:



http://fr.wikipedia.org/wiki/Centrale_n ... re_d%27Ohi
http://en.wikipedia.org/wiki/%C5%8Ci_Nu ... ower_Plant

It concerns units 3 and 4 of the plant. These are Westinghouse 4 loop PWRs like ours. They have twenty years of service.

The power plant is installed by the sea. The ground of the power plant is about forty meters above sea level against eleven meters in Fukushima.

Coordinates: 35 ° 32 ′ 26.25 ″ N, 135 ° 39 ′ 7.32 ″ E

Cesium in Tokyo Bay, in dangerous quantities, if you eat shellfish.

the rats even 70km from Fukushima are full of Cesium !!
and men will do the same, and alive 40 times longer, they will suffer much more, by accumulation of doses !!

The photo of the power plant shows that there is a big risk of mountain collapse on the power plant, especially if a strong earthquake !!!!
Madness to believe in infallibility !!!!

40 times longer than the rat? Knowing that a rat lives 2,5 to 3 years, that makes 100 to 120 years of life expectancy in irradiated humans, not bad ... What is the life expectancy of a rat according to its contamination with cesium 134 or 137?

.... The photo of the power plant shows that there is a big risk of mountain collapse on the power plant, especially if a strong earthquake !!!!

No, no earthquake or tsunami. This time there will be torrential rains causing torrents of mud. There will be an emergency shutdown of the plant, followed by difficulties in starting and / or operating the emergency circuits submerged in the mud, the impossibility of intervention by the rescue teams because of the mud and a new nuclear disaster.

In recent years, torrential rains have become frequent in Japan.
