[Video/Photo] The dead robot reported 10 Sv/h in Reactor 1 / Grating covered with something like yellow glue

Following up this article.. The first robot that entered Reactor 1 died in 5 hours [URL]

 

On 4/13/2015, Tepco announced the dead robot had reported it measured approx. 10 Sv/h in Reactor 1 before it went out of order.

The robot was investigating the ground floor of PCV (Primary Containment Vessel) in Reactor 1.

The report shows the atmospheric dose was 7 〜 10 Sv/h. Temperature was around 20℃.

The video of 2:39 length shows steam coming up from the basement floor of PCV, where Tepco assumes molten fuel is retained, and grating was covered with something like yellow glue. The screen is full of white spots due to the extremely high level of radiation.

 

Tepco announced they gave up collecting the robot. They will cut off the cable and will not send the second robot until they figure out the reason why the robot went out of order.

[Vidéo/Photos] Le robot “mort” a indiqué 10 Sv/h dans le réacteur 1 / Grille couverte d’une sorte de colle jaune

 

Article lié : Le premier robot introduit dans le réacteur 1 est mort en 5 heures

Le 13 avril 2015, Tepco annonce qu’avant de tomber en panne le robot mort avait transmis relever environ 10 Sv/h dans le réacteur 1.
Le robot explorait le plancher de la PCV (Primary Containment Vessel = Enceinte de confinement primaire) du réacteur 1.
Le compte-rendu montre que la dose ambiante était entre 7 et 10 Sv/h. La température autour de 20 ℃.
Une vidéo de 2:39 montre de la vapeur sortant du plancher de la PCV, là où Tepco suppose que le combustible fondu se trouve et les grillages sont recouverts de quelque chose comme de la colle jaune. L’écran est plein de points blancs à cause de la radioactivité extrême.

Tepco déclare qu’ils abandonnent l’idée de récupérer le robot. Ils vont couper le câble et n’en enverront pas d’autre tant qu’ils ne trouvent pas pourquoi celui-ci est tombé en panne.

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.
