1.2 Sv/h measured on unidentified substance overflowing of Reactor 2 / Two parts concealed on Tepco’s source

On 6/29/2015, Tepco announced they detected 1197 mSv/h near unidentified substance overflowing from PCV 2 (Primary Containment Vessel of Reactor 2). Because the highest detectable level of the used dosimeter was 1000 mSv/h, the actual radiation level can be higher than 1197 mSv/h.

 

In order to collect image data of the inside of PCV 2, Tepco was investigating the access hole on the wall.

The substance was found overflown from the lid of the hole by a remote control robot called “PackBot”.

The second highest reading was 1150 mSv/h. The composition of the substance has not been announced.

 

Additionally, on Tepco’s source to indicate the location of the issued hole, there are two parts concealed. (Blue circled on the photo attached below)

It is not known what they tried to hide from the press release.

1.2 Sv/h relevé sur une substance inconnue débordant du réacteur 2 / Deux parties censurées dans la source de Tepco

Le 29 juin 2015, Tepco annonce qu’ils ont relevé 1197 mSv/h à proximité d’une substance inconnue débordant de la PCV2 (Primary Containment Vessel of Reactor 2 = Enceinte de confinement primaire du réacteur 2). La radioactivité réelle peut être supérieure à 1197 mSv/h car le maximum détectable par le dosimètre utilisé était de 1000 mSv/h.

Tepco explorait le trou d’accès dans le mur pour obtenir des images de l’intérieur de la PCV2,
La substance a été découverte en train de déborder du couvercle posé sur le trou par les caméras d’un robot télécommandé nommé “PackBot”.
Le second relevé record a été de 1150 mSv/h. La composition de la substance n’est pas communiquée.

De plus, dans le document source de Tepco localisant le trou en question au moins deux éléments sont censurés (cercles bleus sur la photo ci-dessous).
On ne sait pas ce qu’ils essayent de cacher dans le communiqué de presse.

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.
