[Video / Photo] Reactor 1 investigation result by second robot / Grating covered with blue-green stuff
Following up this article.. Tepco sent the second robot to Reactor 1 [URL]
From 4/16 to 4/17/2015, Tepco published the report of the second investigation in Reactor 1 PCV (Primary Containment Vessel).
This second robot is still remaining in Reactor 1. They published 10 photos and 1 video in total, but images of the basement floor, where molten fuel is assumed to be retained were not published for some reason.
As far as Tepco reports, the atmospheric dose was 4.7 – 8.3 Sv/h. Temperature was approx. 20℃.
The video shows steam coming up from the basement floor, and the grating is covered with something like yellow glue as the first robot reported.
Some parts in the screen look blue-green. It’s not identified.
Les 16 et 17 avril 2015, Tepco a publié un rapport sur la seconde exploration de la PCV (Primary Containment Vessel = Enceinte de confinement primaire) du réacteur).
Ce second robot est toujours dans le réacteur 1. Ils publient 10 photos et 1 vidéo en tout mais les images des fondations où le combustible fondu est supposé se trouver ne sont pas publiées.
Pour ce que Tepco en rapporte, la dose ambiante variait entre 4,7 et 8,3 Sv/h. La température était d’environ 20 ℃.
La vidéo montre le panache de vapeur sortant des fondations et la grille est couverte d’une sorte de pâte jaune comme le premier robot l’avait montré.
Certaines parties de l’écran apparaissent bleu-vert.
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.
