Underground wall not frozen for 2 months

Following up this article.. [Photo] Tepco experimentally started freezing the underground wall to surround 4 crippled reactors [URL]


On 7/1/2015, Tepco announced 12 of 18 underground thermometers still indicate temperature to be above 0 ℃.

The freezing test started over 2 months ago, however still they don’t manage to freeze the ground.

The highest temperature was + 10.1 ℃, which was observed in the west side of Reactor 4. At this point, temperature has almost not been decreased since the end of April.

The reason was not even mentioned in their report.

Originally Tepco planned to complete the freezing test within a few weeks but they officially announced they can’t predict when they manage to freeze the tested area of the ground.

Le 1er juillet 2015, Tepco déclare que 12 des 18 thermomètres souterrains indiquent toujours une température au-dessus de 0 ℃.

Le test de congélation a commencé il y a plus de 2 mois, ils n’arrivent néanmoins toujours pas à congeler le sol.
Le record de température est de + 10,1 ℃, il a été relevé sur le côté ouest du réacteur 4. La température n’a pratiquement pas diminué depuis fin avril à cet endroit.
Leur rapport n’en donne aucune explication.
Au départ, Tepco prévoyait de terminer le test de congélation en quelques semaines mais ils annoncent officiellement qu’ils ne peuvent prédire quand ils vont arriver à congeler le sol de la zone de test.


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.
