[Reservoir Leakage] Tepco not to weld the new emergency tanks of 19,000m3

About the major leakage of highly contaminated water, Tepco is transferring the water from the leaking reservoirs to the “safer” tanks.

According to Tepco, they are going to transfer 8,400 m3 in reservoir No.3 and 7,500 m3 in reservoir No.6 to the new tanks from late May.

The new tanks are to have 19,000 m3 of capacity, but they haven’t been built. Tepco is still improving the ground.

On the press conference of 5/2/2013, Tepco’s spokesman stated these potential tanks will not be welded.

Tepco is going to choose the flange type of the tanks because it’s easier to build.

In 3/11/2013, Fukushima Diary reported “27% of the highly contaminated water tanks will need repairs in 2016, “1,000 tones for each” [URL]”

Tepco is running out of the capacity to stock contaminated water, they are planning to discharge it to the sea.
However, 270 of 1,000 existing tanks will need repairs from around the spring of 2016 too.
These tanks (1,000 tones per each) were built provisionally just after 311. They are not even welded, only made by bolts and water stops. The gasket parts don’t last for over 5 years.

In 2016, Tepco will also run out of the spaces to build new tanks as well. Because Tepco needs to repair the tanks and also find the space to build new tanks while they build new tanks, they might discharge further volume of contaminated water to the sea.


The major leakage happened due to their provisional measures. For the countermeasure, they are going to take another provisional means.

[Fuites des réservoirs] Tepco n’a pas soudé les nouvelles citernes d’urgence de 19 000 m³


Concernant la fuite majeure d’eau extrêmement contaminée, Tepco va transvaser l’eau des réservoirs percés vers des citernes “plus sures”.

Selon Tepco, ils vont transvaser 8 400 m³ du réservoir N°3 et 7 500 m³ du réservoir N°6 dans les nouvelles citernes pour fin mai.
Les nouvelles citernes auront une capacité de 19 000 m³ mais elles sont encore à construire. Tepco est toujours en train de stabiliser le sol.
A la conférence de presse du 2 mai 2013, le porte-parole de Tepco a affirmé ces futures citernes ne seront pas soudées.
Tepco a choisi un type de citernes à emboitements parce que c’est plus facile à monter.

Le 11 mars 2013, le Fukushima Diary rapportait 27% des réservoirs à eaux hautement contaminées vont nécessiter des réparations en 2016, “1 000 tonnes chacun” :

Tepco arrive au bout de ses capacités de stockage des eaux contaminées, ils prévoient de les déverser en mer.
Cependant, 270 des 1 000 réservoirs existants ont et auront besoin de réparations à l’horizon du printemps 2016.
Ces réservoirs (de 1 000 tonnes chacun) ont été construits de façon provisoire juste après le 11-3. Ils ne sont même pas soudés, seulement boulonnés et étanchéifiés. Les joints ne dureront pas plus de 5 ans.

En 2016, Tepco va aussi manquer de place pour construire de nouveaux réservoirs. Parce que Tepco a besoin de réparer les réservoirs et aussi de trouver de la place pour en construire de nouveaux, ils se pourrait qu’ils déversent plus d’eaux contaminées en mer.

La fuite majeure a été provoquée à cause de leurs mesures provisoires. Leurs contre-mesures le sont tout autant.

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.
