Steal beam truss on the top of reactor3 possibly starting to be deteriorated

At this moment, the worst crippled reactor3 still has its spent fuel pool on the top of the building.

It is still directly exposed to the atmosphere. Tepco is trying to install the pool cover but the broken steal beam truss is preventing it from being completely installed.

On 5/27/2013, they released the latest image of the top of reactor3 building.

The images are the screen capture of a video, which are unfairly small to see details. However, as long as the images show, the exposed steal beam trusses are turning to be red.

It suggests the possibility that the steal beam trusses are possibly starting to be rusted. The reliability of reactor3 building is becoming one of the major concerns.

La cage de poutres d’acier du sommet du réacteur 3 a sans doute commencé à se détériorer

 

En ce moment, la piscine à combustibles usagés  du réacteur 3, le plus endommagé, est toujours en haut du bâtiment.

Elle est toujours au contact direct avec l’atmosphère. Tepco essaye d’installer un couvercle mais  la cage en poutres d’acier effondrée les empêche de le terminer.
Le 27 mai 2013, ils publient l’image la plus récente du sommet du bâtiment du réacteur 3.
Ces images sont des capture d’écran d’une vidéo qui est déloyalement petite pour empêcher de voir les détails. Cependant, pour autant que les images le montrent, les poutrelles d’acier de la cage virent au rouge.
Ceci laisse penser que ces poutres d’acier ont commencé à rouiller. La fiabilité du réacteur 3 est en train de devenir un des soucis majeurs.

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.
