Following up this article.. Tepco to start building frozen water underground wall tomorrow (6/2/2014) / 1.5 km, 30m deep, 1550 pipes [URL]

 

On 4/28/2015, Tepco announced they were going to experimentally freeze the water underground wall from 12:00 of 4/30/2015.

It is the 3 mountain sides of the wall to surround 4 crippled reactors. The seaside will not be frozen yet.

Tepco is going to freeze 58 frozen ducts to see the earth temperature trend. The collected data is supposed to be weekly reported from the 3rd week of May.

[Photos] Tepco démarre la congélation du mur souterrain autour des 4 réacteurs dévastés à titre expérimental

 

Article lié : Tepco va commencer demain (6 juin 2014) la construction du mur souterrain congelé : 1,5 km, hauteur de 30 m , 1 550 tuyaux

Le 28 avril 2015, Tepco a annoncé qu’ils allaient tenter une congélation expérimentale de l’eau du mur souterrain le 30 avril 2015 à partir de 12:00.

Il s’agit des trois pans côtés montagne du mur qui encercle les 4 réacteurs dévastés. Le côté mer ne sera pas congelé tout de suite.
Tepco va congeler 58 canalisations de congélation pour observer l’évolution de la température dans la terre. Les données récupérées sont supposées être publiées hebdomadairement à partir de la 3e semaine de mai.

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.
