[Video] Tepco investigated equipment hatch of Reactor 3 PCV / “Next time, use robot with a smartphone”

On 9/9/2015, Tepco investigated the equipment hatch of PCV 3 (Reactor 3 PCV) with a portable camera.

They reported the hatch is not leaking coolant water from the inside of PCV 3, nor was damaged however the floor was wet and didn’t confirm where the water was leaking.

None of the atmospheric dose or nuclide analysis data was released. On the other hand, the video shows the white noise caused by extremely high level of radiation.

 

Considering what they have found in this investigation, Tepco is to decide to send a remote-controlling robot for the next phase. The robot is planned to carry a “smartphone camera” for some reason.

[Vidéo] Tepco a exploré la trappe de la PCV du réacteur 3 : “La prochaine fois on utilisera un robot avec un smartphone”

 

Le 9 septembre 2015, Tepco a exploré la trappe de l’équipement de la PCV 3 (enceinte de confinement primaire du réacteur 3) avec une caméra portable.

Ils rapportent que l’eau de refroidissement de la trappe ne fuit pas de l’intérieur de la PCV 3 et que la trappe n’est pas endommagée mais le sol est humide et ils n’ont pas pu confirmer d’où l’eau fuit.
Aucune donnée de dose ambiante, ni d’analyse des nucléides atmosphériques n’est communiquée. De son côté, la vidéo présente le caractéristique bruit blanc provoqué par un niveau extrêmement élevé de radioactivité.

Compte tenu de ce qu’ils ont trouvé au cours de cette exploration, Tepco a décidé d’utiliser un robot télécommandé pour la prochaine phase. Ce robot est prévu équipé d’un “appareil photo de type smartphone”.

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.
