Unverified highly radioactive sediment collected from 8.6m inside of reactor2 PCV again, “30 mSv/h of γ&β dose”

Unverified highly radioactive sediment collected from 8.6m inside of reactor2 PCV again, "30 mSv/h of γ&β dose"

Following up this article..[Elephant foot ?] Tepco collected highly radioactive sediment in reactor2 PCV, “0.2 Sv/h of γ and β” [URL]

In the second TIP (Traversing In-core Probe) guide pipe soundness test, Tepco collected the same highly radioactive sediment again.

TIP is the sensoring system to monitor gamma and neutron.

They inserted the dummy TIP cable for 8.6 m into reactor2 PCV. The sediment was attached on the top of the cable.

It was 2~3mm, looks gray gold. γ dose was 14 mSv/h, γ & β dose was 30 mSv/h.

It is not verified what this substance is made of.

Encore de la boue radioactive au bout du câble introduit dans la PCV2 : 30 mSv/h de γ & β

 

Unverified highly radioactive sediment collected from 8.6m inside of reactor2 PCV again, "30 mSv/h of γ&β dose"Article lié : [Pied d’éléphant ?] Tepco ramasse un sédiment hautement radioactif dans la PCV2 : 0,2 Sv/h de γ+β

Au cours du second examen de fiabilité du tube guide du TIP (Traversing In-core Probe), Tepco a encore ramassé un peu de la même boue hautement radioactive.

Le TIP est le système de de capteurs qui gère les neutrons et les radiations gamma.
Ils ont introduit un câble sur 8,6 m dans le TIP de l’enceinte primaire du réacteur 2 (PCV2). La boue était collée à l’extrémité du câble.
Ça faisait 2 à 3 mm, d’apparence gris-doré. La dose en γ était de 14 mSv/h, les γ & β de 30 mSv/h.
On ne sait pas de quoi est constituée cette substance.

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.
