Fukushima Daiichi: the situation (one year) after (ASN and IRSN)

[Bardal]

... / ...

PS: I did not find the documentation announced on the theory of the absence of threshold or linear rule without threshold.

The problem is not too badly explained in https://fr.wikipedia.org/wiki/Linéaire_sans_seuil , as well as the precautionary principle applied by the bodies responsible for radiation protection, applying, and it is fair, a rigorous precautionary principle in matters of prevention.

but "However, although the LNT model remains a scientifically plausible element for its practical system of radiological protection, the Commission stresses the fact that biological / epidemiological information which would allow to unambiguously verify the assumptions underlying the LNT model are lacking ( see UNSCEAR, 2000; NCRP, 2001). Due to this uncertainty about the health effects of low doses, the Commission considers it inappropriate, for public health purposes, to calculate the hypothetical number of cases of cancers or hereditary diseases that could be associated with very low doses of radiation received by large numbers of people over very long periods of time.

Is it true that the Fukushima nuclear accident caused no deaths? https://www.liberation.fr/checknews/201 ... rt_1720075

In summary for workers in the plant: one dead and five sick were associated with the radiation, 10 dead were not associated with the radiation and 16 were injured due to the explosions.

and none in the population.

Excuse me but it is (again) to show a sacred euphemism and even to be more precise: a shocking untruth if we stick to the elements of answer given by the article to its title! Yes Fukushima has caused deaths in the population. We no longer speak here of deaths induced directly by radioactivity but of deaths due to evacuation, to the stress of rehousing, to the maintenance of certain categories of these populations in refugee situations because of the contamination of their place of life. origin for 7 years, and finally, lately, to the forced returns to these deserted areas of (for example) elderly people without resources, some of whom prefer to choose suicide rather than considering an atomically artificialized life because cut off from its cultural, natural environment and social!

And if we follow the scientific results of 3 different analyzes, including one from an official Japanese institution, mentioned in the Liberation article on this subject (are they "irrational", "ideological"?, Do they show a will to play with our childhood fears?) the number of deaths in question would be 2211 or 2267 (according to studies) and therefore greater than those attributable specifically to the natural disaster (tsunami, earthquake) in the Fukushima sector (whose number is 1605)! Rationality, so much praised by some, forcing us here obviously to avoid comparing the sector of Fukushima (area of ​​40 km in diameter) with the region of Tōhoku affected by the tsunami (400 km of coastline and 18 dead for the record )!

I also encourage you to read one of these analyzes in full. The observation is entirely in line with what I mentioned earlier on the incredible and impossible situation of atom refugees. Everyone knows a minimum about Japanese culture ... How can a Japanese native of this rural and wooded region choose for himself to come back, when he will not be able to pick wild mushrooms, which he will strongly hesitate to buy locally caught fish (if it is not prohibited for sale), when he will have no neighbor, while the maintenance of the rice fields has been abandoned for 7 years, that his house is perhaps to be devastated since time, that nature is strongly contaminated and that it regains on habitable areas?

And I could bet that we will review this kind of situation during (probable) future nuclear accidents, especially when we see the state of discourse and reflection on nuclear power, in France in particular, and on certain forums in particular.

The death toll is serious due to the IDPs and the tsunami, but the radiation damage is limited to one death.
Believe it or not, this is what emerges from this article, as official documents.

It will run out of space in 3 years in Fukushima for the storage of contaminated water.
Currently 1 million m3 stored.

The utility company operating Fukushima's tsunami-devastated nuclear power plant said Friday it will run out of space to store massive amounts of contaminated water in three years, adding pressure on the government and the public to reach a consensus on what to do with it.

Three reactors at the Fukushima Dai-ichi plant suffered meltdowns in a massive 2011 earthquake and tsunami that devastated northeastern Japan.

Radioactive water has leaked from the damaged reactors and mixed with groundwater and rainwater at the plant. The water is treated but remains slightly radioactive and is stored in large tanks.

The plant has accumulated more than 1 million tons of water in nearly 1,000 tanks. Its operator, Tokyo Electric Power Co., says it plans to build more tanks but can accommodate only up to 1.37 million tons, which it will reach in the summer of 2022.

But where to swing all this piss? Some have ideas.

Tokyo Electric Power (Tepco) will release radioactive water directly into the Pacific Ocean, Japanese Environment Minister Yoshiaki Harada announced on Tuesday September 10, 2019.

Why don't their closest neighbors like it?

By the way, the estimates keep going up (when I think I was so small arm with my 100 billion!) And
Fukushima is now considered the most expensive industrial disaster in history.

The Japanese Institute for Economic Research (JIER) estimated last July that the total cost of this industrial disaster, dismantling and decontamination included, should reach over 40 years 35 to 000 billion yen, between 80 and 000 , 295,5 billion euros.

No problem, nuclear Kw is the cheapest in the world, and it doesn't pollute.

Latest news: Welding problems on "certain French nuclear power plants", EDF shares are down 8% (France-Inter).

The primary circuit of our reactors leaks permanently, it is "normal".
Above 400 liters per day we worry about it and we can shut down the reactor for repair.
Below this limit, the water is collected and reinjected into the primary circuit.
About twenty years ago, AREVA filed a patent for an expansion vessel which allows precise knowledge of the water level in the primary circuit. Before, it was a bit off the cuff.
