Five years later, Fukushima remains a huge challenge for Japan

March 11 2016 Le Figaro

GRAPHICS / VIDEO - The March 11 2011, a powerful earthquake struck Japan, triggering a tsunami and a nuclear accident including the assessment of consequences is not complete. Five years later, hundreds of thousands of people remain exiled and technical means to clean the center and the irradiated areas remain to imagine.

Five years after Fukushima, the accident is still ongoing

By Ludovic Dupin Usine Nouvelle on March 11 2016

Japan collects on the fifth anniversary of the tsunami of March 11 2011 and nuclear accident he caused. On the Fukushima site, work continues because the three damaged reactors are barely under control.

The March 11 2011, an earthquake and tsunami hit Japan. Flooding in the Fukushima causes loss after another for power and water supply. The hearts are warming, eventually bursting into releasing massive amounts of hydrogen. Gas explodes, ripping three of the six reactors on the site.

Since then, the operator TEPCO is working to stabilize the situation of the site for its dismantling. "Five years after the accident, efforts continue to control facilities in a persistently difficult environment linked to a still limited knowledge of the state of the reactors and damaged buildings"Judge Institute of Radiation Protection and Nuclear Safety (IRSN) in an information note compiling the state of knowledge.


He adds : "The groundwater pollution due to containment barriers degradation always leads to diffuse radioactive releases into the environment".

always fuel cooling

"The reactors 1, 2 3 and are maintained at a temperature between 20 ° C and 50 ° C by injection of about 5 cubic meters per hour of fresh water per reactor", ensures SNRIs which states that a nitrogen injection is maintained within the containment to avoid further risk of explosion.

Swimming pools, in turn, are cooled by a closed water circuit in order to stay below 30 ° C. Emptying the spent fuel they contain should have started from 2015, but Tepco had to postpone these operations. "The withdrawal of fuel present in the pools (provided) from 2017 for the pool of reactor No. 3, 2020 from those for reactor No. 1 and 2 No." reports IRSN.

As for the withdrawal of fuel in the reactors degraded, it is anticipated that between 2020 and 2025. The note states that these deadlines are to be considered as indicative as many characterization work of the state of the facilities are still needed.

contaminated water volumes of accumulating

For five years, the work on the management of contaminated water - the water used for cooling cores and the end of the natural runoff - is the first fight. "The volume of water accumulated in storage tanks and basements of buildings to reach early 2016 900 000 near cubic meters" IRSN reports, the equivalent of 300 Olympic swimming pools.

Part of this water has been treated to extract the cesium and strontium. Even if there are traces of radioactivity, primarily tritium, Tepco expects a discharge authorization of these waters. According IRSN, Tepco today would have a storage capacity of 1 million cubic meters.

In addition to these water stored in about 3 000 containers, Tepco must also manage about 70 000 cubic meters of heavily irradiated water in basements rough buildings. "In addition, they suffer significant water inflows (about 200 m3 / day) from the table," added the IRSN.

5 years after the frightening balance Fukushima ...

VIDEO. The number of victims of radioactive leaks caused by the tidal wave which hit Japanese nuclear power plant continues to grow.

The Fukushima disaster, which began on March 11 2011, is it really over? Five years later, the radioactive leakage caused by the tidal wave which hit Japanese nuclear power plant, medical authorities note with dismay that the human toll of the accident continues to increase. According to calculations by Tokyo Electric Power Company (Tepco), which operated the affected plant, toxic emissions would have been ten times less than those of Chernobyl, the April 26 1986. The fact remains that almost 32 million Japanese were exposed to iodine fallout 131, consecutive to runaway of the three reactors at the nuclear power plant.

By searching this topic here: search.php

I had some "fun" pubs:

Pub_fukushima.png


And some complain that the ad is not targeted well enough !! No but !!
So you have a choice: 1 2 flight and hotels in Fukushima to study the reconstruction of a nuclear plant !! : Cheesy: : Cheesy:

Good without laughter are still a few marketers who deserve slaps ... obviously this is robotic but still ... a small blacklist of not great destination would be welcome ... it also works with you Mururoa and Chernobyl believe?

Like wild life in Chernobyl, the population of wild pigs, or wild boar, has increased very rapidly in the Fukushima area. A situation that worries local authorities

Yes, it is glorious! This is a tool closer to the reality that the angelic reportage and obsolete ARTE Chernobyl ...!
That said at least the way things are in the field.

The population explosion (in enormous suffering) is easily explained by the shortening of life expectancy (high mortality due to radiation, the animals know it) then offset by the increase in the number of small and litters necessarily "unhealthy" tasks females. (It is noted that even in the human species or population explosion there in all countries with high infant mortality ... when famine reign)

Because experience proves it Radon, since we are exposed there it has been almost 5'000 years, there has been no kind of adaptation of the human species on this radioactive gas, yet original natural. It is always so deadly and we must always preserve.

The author of a study on this subject, JT Smith, had said: "(The growth of wildlife populations at Chernobyl) does not mean that radioactivity promotes life, but human activities (perpetuated in normal times; ed) do more damage than you might think".
Goes in the direction of what I wanted to express. When will stop you distort my words :?:

Yes that I understood the background of your thought Izentrop, but it should not obscure the general discourse on bogus "resistance" radiation is still FALSE (or unacceptable from a human point of view of the balance sheet given the losses that means ... 1 millions of deaths "admitted" currently on 70 years, not counting the Fukushima disaster ...).

By the way I do not know where you hold this idea, but concerning the breeding birds, their population quintupled in 15 years:

I do not know what you mean, we're not on the right topic, Fukushima is too fresh.
Besides breeding birds in Switzerland are not representative of biodiversity elsewhere.
They are not stopped by the obstacles that man inflicts on the flora and fauna, especially in the mountains or the man has less impact.
It is mostly land animals and insects who suffer most. Incidentally, the fish also.

Concretely an example: One of the last French predator, lynx is disappearing des Vosges. By lack of staff, it is not reproduced and the little that remains is crushed on the roads. I did not find a link on the Internet. The Pyrenean bears is replaced by Slovenians in recent years and the lobby of hunters and herders take precedence over ecology.

I do not want nuclear disasters, but does not prevent areas where man is prohibited are "biodiversity haven," far more than the reserves that are not on many points.

Edit: The fox like pigeon adapt very well to humans, especially in London and the parks are everywhere.
And then the Swiss and London are representative of biodiversity in the world?

yes, I take very different examples and places far away (or not) and find that nature is not so bad, in my corner there are fish ladders so they can go up the rivers for the spawning. Roads are built under the roads to allow animals to pass etc. I also live in France figure you, and you should get out of your hole because nature does not go so bad! In short, I do not know why, but you bring some "beautiful" forumWhat is your goal?
