[Video] Over 48 Sv/h was detected by the robot in Reactor 1 / Tepco did not officially report

Following up this article.. Tepco to abandon the second robot in Reactor 1 again / Camera went out of order due to high level of radiation [URL]


Tepco’s own video captured the moment when the second robot detected over 48 Sv/h.

On 4/20/2015, Tepco announced they were going to abandon even the second robot, and added two videos to the photos that were already released.

Both of the videos capture the steam coming up from the basement floor of PCV (Primary Containment Vessel), and the second video shows the atmospheric dose rose up to 48.2 Sv/h.


On 4/20/2015, Tepco was reporting the detected atmospheric dose was 4.1 – 5.9 Sv/h.

La propre vidéo de Tepco a capturé le moment où le the second robot a détecté plus de 48 Sv/h.

Le 20 avril 2015, Tepco annonçait qu’ils abandonnaient même le second robot et ajoutaient deux vidéos aux photos qui étaient déjà publiées.

Les deux vidéos montrent la vapeur sortant des fondations de la PCV (Primary Containment Vessel = Enceinte de confinement primaire) et la seconde vidéo montre une dose ambiante montant jusqu’à 48.2 Sv/h.

Le 20 avril 2015, Tepco rapportait que la dose ambiante relevée se situait entre 4,1 et 5,9 Sv/h.

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.
