JP Gov to decide to abort the preceding “frozen water wall” project on 8/19/2014

NRA (Nuclear Regulation Authority) is going to decide to abort the frozen water wall project in underground trench on 8/19/2014.

This is the frozen water wall  project followed by frozen ground wall project, which is to separate the underground trench from turbine buildings.

Because it needs to freeze the water, it is considered to be more difficult than frozen ground wall. However the decision of NRA may affect the entire frozen wall projects.


Tepco started injecting the coolant material in the end of April. They also put 250 t of ice and even dry ice but it hasn’t been frozen by now.

NRA is going to hold a feedback session on 8/19/2014 to decide if they should continue the frozen water wall project or not.

Le gouv JP décide d’abandonner le projet précédent de “mur d’eau congelée” au 19 août 2014


La NRA (Nuclear Regulation Authority) va décider d’abandonner le projet de mur d’eau congelée de la tranchée souterraine à partir du 19 août 2014.
Il s’agit du projet de mur d’eau congelée prolongé par celui de mur souterrain congelé qui devait séparer la tranchée souterraine des bâtiments de la turbine.
C’est considéré comme plus difficile que le mur de terre congelée parce qu’il faut congeler l’eau. Cette décision de la NRA pourrait concerner tous les projets de murs congelés.

Tepco avait commencé à injecter le liquide refroidisseur à la fin avril. Ils ont également mis 250 tonnes de glace et même de glace sèche mais ça n’a toujours pas congelé à ce jour. (cf. Tuyaux d’évacuation bouchés par la glace sèche pour le mur congelé)

La NRA va tenir une réunion de bilan le 19 août 2014 pour décider si ils continuent le projet de mur d’eau congelée ou non.

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.
