[The only countermeasure] Tepco pumping up leaked water to return to the crippled reservoirs

About the major leakage of highly contaminated water reservoir, Tepco announced the press release.

In the report, Tepco states they are pumping up the leaked water to return to the crippled reservoirs. According to Tepco, those reservoirs are leaking until early June.

Now pumping up water to give it back to the reservoirs is their only countermeasure.

In order to prevent the water leaked into the leakage detection hole of the underground reservoir No.1 from leaking into the ground in the surrounding area, the water in the leakage detection hole in the northeast side was returned to the underground reservoir from 3:40 PM to 3:41 PM (approx. 1 minute) via a temporary pump. The same was done for the leakage detection hole in the southwest side at 4:05 PM (approx. 30 seconds).

Also, the soil covering the penetration of the leakage detection hole (in the northeast side) of the underground reservoir No.2 has been removed in order to perform visual inspection on the penetration. The removal of the impermeable sheet, gravels, etc. will be continued tomorrow (April 11) and on later days.

Furthermore, for the boring investigation to be performed the purpose of confirming the contamination condition near the underground reservoirs and contamination expansion into the area in the sea side, equipment installation and trial drilling work are currently being carried out. The work will be continued tomorrow and on later days.

[La seule contre-mesure] Tepco pompe l’eau qui fuit pour la remettre dans les réservoirs endommagés


Sur la fuite majeure des réservoirs à eaux extrêmement radioactives, Tepco émet un communiqué de presse.

Dans ce rapport, Tepco affirme qu’ils sont en train de pomper l’eau qui fuit pour la remettre dans les réservoirs percés. Selon Tepco, ces réservoirs vont fuir jusqu’à début juin.

Actuellement, pomper l’eau pour la remettre dans les réservoirs est leur seule contre-mesure :

“Pour empêcher l’eau qui fuit par le trou de détection du réservoir N°1 de fuir dans le sol environnant, l’eau de la fuite du trou de détection du côté nord-est a été remis dans le réservoir souterrain de 15:40 à 15:41 (approx. 1 minute) via une pompe provisoire. La même chose a été faite au trou de détection côté sud-ouest à 16:05 (approx. 30 secondes).

De plus, le sol recouvrant le point de fuite du trou de détection (côté nord-est) du réservoir enfoui N°2 a été retiré pour permettre des inspections visuelles de la fuite. Le retrait des feuilles d’étanchéité, des graviers, etc. sera poursuivi demain (11 avril) et les jours suivants.

En outre, pour permettre les investigations par sondage devant confirmer l’état de la contamination près des réservoirs enfouis et de l’extension de la contamination dans la zone côté mer, l’installation d’équipements et des travaux d’essais de forages sont actuellement en cours. Ce travail se poursuivra demain et les jours suivants.”

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.
