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.
