Tepco to consider freezing ground for 1400m to stop ground water flowing into the plant

On 5/30/2013, the committee of experts suggested Tepco to stop ground water flowing into the plant by freezing the ground.

This is the technology to install freezing ducts underground to circulate the coolant material (eg, -40℃) inside so it freezes the soil around.

Currently 400 tones of ground water flow into the plant on the daily basis. Tepco is running out of the contaminated water storage.

It is to surround reactor1 ~4 by the underground wall of frozen soil for 1400m.

Tepco considered the feasibility of building the underground wall of frozen soil in 2011. However, in order not to let contaminated water overflow from the plant backward, they would need to recharge the ground water on purpose. Also, the lifetime of the wall is up to 2 years, when they need it to last over 10 years.

The real problem behind Fukushima accident was “Everyone wanted a LIE.”
Fukushima accident was physically an end. However, it was socially nothing but a check point. As time passes, it’s becoming clear.
By taking advantage of their old brand as “hardworking and honest”, they were depraved to blind themselves from reality.
Media blackout can’t stand without the demand.
By sacrificing the long-term benefit, they will increasingly seek short-term benefit. We don’t have a long way to convergent point.
Not to mention, Fukushima Diary says No to it, anytime, anywhere.

Tepco envisage de congeler le sol sur 1 400 m pour empêcher l’eau d’inonder la centrale

 

Le 30 mai 2013, le comité d’experts a suggéré à Tepco d’empêcher les eaux souterraines d’inonder la centrale en congelant le sol.

La technique consiste à installer des tuyaux de congélation en sous-sol pour y faire circuler le liquide congélateur (ie.  -40 °C)  de façon à congeler le sol qui est autour.

400 tonnes d’eaux souterraines entrent actuellement dans la centrale tous les jours. Tepco est en manque d’espace de stockage pour les eaux extrêmement radioactives.

L’idée est de ceinturer les réacteurs 1 à 4 avec un mur souterrain de sol gelé sur 1 400 m.

Tepco avait examiné la faisabilité de cette construction en 2011. Ceci dit, pour empêcher les eaux extrêmement radioactives de sortir de la centrale, ils vont  avoir besoin de recharger exprès le sous-sol en eau. De plus, l’espérance de vie de ce mur est de 2 ans, alors qu’ils en ont besoin pendant plus de 10 ans.

Derrière l’accident de Fukushima le vrai problème était que “Tout le monde voulait du MENSONGE”.
L’accident de Fukushima était physiquement une fin. Socialement cependant, ce n’était rien d’autre qu’un point de passage. Plus le temps passe, plus c’est clair.
Ils se sont pervertis eux-mêmes en s’aveuglant contre la réalité en se cachant derrière leur ancienne image de marque de “travailleurs honnêtes”.
La censure médiatique ne tient pas sans demande.
Ils vont de plus en plus chercher des avantages à court-terme en sacrifiant le long terme. Nous ne sommes plus très loin du point de convergence.
Il va sans dire que le Fukushima Diary le refuse, en tout temps et en tout lieu.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
