Cs-134 detected from “steam” in reactor3 / Tepco “not sure if it was rain”

Following up this article..[Steaming reactor3] Tepco “The steam is the heated rain, same thing happened last year but didn’t report it” [URL]

According to Tepco, the steam was not observed at 8:00 AM of 7/19/2013. The temperature was 22.9 ℃, humidity was 78.5 %.

Having commented it was the heated rain on 7/18, in the press conference of 7/19/2013 they stated they are not sure about what it was.

They announced the dust sampling result of the steaming area. The highest readings were below,

Cs-134 : 1.3×10^2 Bq/m3

Cs-137 : 2.7×10^2 Bq/m3.

Tepco states this is within the range of past 6 months.

However, in the dust sampling of the same location on 7/4/2013, Cs-134 was under the detectable level.

The reason why Cs-134 was detected from the “steam” was not announced.

Du césium 134 dans la “vapeur” du réacteur 3 / Tepco : “pas certain que ce soit la pluie”

 

Article lié : [Réacteur 3 “à valeur”] Tepco : “La vapeur est provoquée par la pluie, il est arrivé la même chose l’an dernier mais on ne l’avait pas rapporté”

Selon Tepco, ce 18 juillet 2013 à 08:00 on ne voit plus de vapeur. La température est de 22,9 ℃, l’humidité de 78,5 %.

Après avoir déclaré le 18 juillet que c’était de l’eau de pluie réchauffée, au cours de la conférence de presse du 19 juillet 2013 ils affirment qu’ils n’en sont plus aussi sûrs.
Ils ont donné les résultats de l’analyse des poussières échantillonnées dans la zone du panache de vapeur. Les records sont les suivants :
Cs 134 : 1 30 Bq/m³
Cs 137 : 270 Bq/m³.
Tepco affirme que c’est dans la moyenne des 6 mois précédents.
Or, le 4 juillet 2013, ils disaient que le Cs 134 était à un niveau non-détectable dans les résultats d’analyse  des poussières du même endroit.
La raison pour laquelle le césium 134 est détecté dans cette “vapeur” n’est pas précisée.

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.
