Former Fukushima worker “Pumping up ground water may cause Fukushima plant a land subsidence”

Currently 400 tones of ground water is flowing into Fukushima nuclear plant every single day.

To reduce the water volume, Tepco is pumping up the ground water in the upstream of the vein. Tepco is already about to discharge the pumped water to the sea soon after they obtain the approval of the stakeholders. (The pumped water is not purified.)

(cf, Tepco is about to discharge pumped ground water to sea, “They won’t remove 21,000 Bq/m3 of Tritium” [URL])

The former Fukushima worker Happy11311 commented on Twitter that it may cause a land subsidence of the plant area.

(Happy11311 had an interview with Tokyo newspaper. The article was published on 5/5/2013.)



An expert of ground water stated there are several veins in Fukushima nuclear plant. If there is another vein downstream of the pumping wells, the water volume to flow into the plant wouldn’t be changed. Besides, the plant area may have a land subsidence depending on the volume of water to pump up. I think Tepco knows that…

Actuellement, 400 tonnes d’eaux d’infiltration inondent la centrale nucléaire de Fukushima chaque jour.


Pour réduire le volume d’eau, Tepco pompe les eaux souterraines en amont de la veine. Tepco prêt à déverser ces eaux pompées directement en mer dès qu’ils auront l’aval des parties prenantes. (les eaux pompées ne sont pas purifiées) (cf. Tepco est sur le point de déverser en mer les eaux souterraines pompées. Ils ne retireront pas les 21 000 Bq/m³ de tritium)
L’ancien travailleur de Fukushima Happy11311 déclare sur Twitter que ça peut provoquer une subsidence du terrain de la centrale.
(Happy11311 a été interviewé par un journal de Tokyo : l’article a été publié le 5/5/2013.)

Un expert des eaux souterraines a affirmé qu’il existe plusieurs veines dans la centrale nucléaire de Fukushima. S’il y a une autre veine en aval des puits de pompage, le volume d’eau qui inonde la centrale ne sera pas changé. En outre, la zone de la centrale peut subir une subsidence de terrain (descente de tout le terrain) selon le volume d’eau qu’ils vont pomper. Je pense que Tepco le sait…

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.
