Tepco is going to give up the preceding water wall project and simply pour cement instead, they announced in the press conference of 9/22/2014.

Extremely highly contaminated water is “retained” in the underground trenches, which are connected to the plant buildings.

Though Tepco is denying this, there is a possibility that these trenches are also severely damaged by the continuous explosions and earthquake, keep letting the coolant water leak underground and sea directly from plant buildings.


Tepco was attempting to separate the plant buildings and trenches by frozen water wall in order to pump up the extrenely highly contaminated water retained in the trenches.


However the frozen water wall has never been completed.

Instead of the frozen water wall, Tepco announced they developed the special type of cement to fill the entire trenches.

In the simple math, if they pour cement, the same volume of contaminated water would be pushed out of the trenches. However Tepco states it would not leak out because they would pump up the contaminated water as they pour cement.


Because the trenches and the plant buildings are connected, they would end up having to pump up the same volume water as the entire capacity of the trenches. Tepco hasn’t announced if they prepare the enough contaminated water storage.

Tepco abandonne le mur congelé et, à la place, va combler les tranchées avec du ciment

Tepco va abandonner le précédent projet de mur congelé et en revenir simplement au béton, ils l’ont annoncé à la conférence de presse du 22 septembre 2014.

Des eaux extrêmement radioactives sont “retenues” dans les tranchées souterraines qui sont reliées aux bâtiments de la centrale.
Bien que Tepco le nie, il est possible que ces tranchées soient aussi gravement endommagées par les interminables explosions et séismes, laissant ainsi fuir le liquide de refroidissement en continu dans le sous-sol puis la mer, directement depuis les bâtiments de la centrale.

Tepco était en train d’essayer d’isoler les bâtiments de la centrale et les tranchées avec des murs d’eau congelée pour pouvoir pomper les eaux extrêmement radioactives des tranchées.

Cependant, les murs congelés n’ont jamais été terminés.
Tepco a déclaré qu’au lieu du mur d’eau congelée, ils développaient un type particulier de ciment pour en combler totalement les tranchées.
En respectant les mathématiques les plus élémentaires, s’ils les remplissent de ciment, le même volume d’eau radioactive va être repoussé hors des tranchées. Néanmoins, Tepco affirme qu’il n’y aura pas de fuite parce qu’ils vont pomper l’eau au fur et à mesure qu’ils combleront avec le ciment.

Ils vont devoir pomper un volume d’eau au moins égal à la capacité totale des tranchées puisque les tranchées et les bâtiments sont reliés. Tepco n’a pas annoncé s’ils préparaient assez d’espace de stockage pour ces eaux extrêmement radioactives.


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.
