Tepco finally admitted irregular sinking in Fukushima plant

On 7/21/2015, Tepco announced Fukushima plant area has irregularly sunk since 311.

It has been known that the reference point sank by 709 mm but Tepco has not reported the height above the sea level of each building.

The report reads Reactor 1 turbine building sank by 730 mm, Reactor 2 by 725 mm, Reactor 3 by 710 mm, Reactor 4 by 712 mm.

However the readings of reactor buildings were not published for some reason.

The buildings can be inclining due to this irregular sinking but the inclining degree has not been announced either.

Tepco finit pas reconnaître des affaissements irréguliers dans la centrale de Fukushima

 

Le 21 juillet 2015, Tepco déclare que depuis le 11-3 le domaine de la centrale de Fukushima s’est affaissé de façon irrégulière.
On savait que le point de référence s’était affaissé de 709 mm mais Tepco n’avait pas donné la position de chaque bâtiment par rapport au niveau de la mer.

On lit dans ce rapport que le bâtiment de la turbine du réacteur 1 s’est enfoncé de 730 mm, celui du réacteur 2 de 725 mm, celui du réacteur 3 de 710 mm, et celui du réacteur 4 de 712 mm.

Néanmoins, les relevés des bâtiments des réacteurs ne sont pas publiés.
Des bâtiments se sont inclinés cause de l’irrégularité de ces affaissements mais leur degré d’inclinaison n’est pas communiqué non plus.

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.
