[Where is the fuel ?] Cs-134/137 density is 6 times higher in torus room than inside of reactor2 vessel

Tepco released the data about the radioactive density in reactor retained water.

The report was submitted to the secretariat meeting for Fukushima decommissioning on 8/29/2013.

From the data, Cesium-134/137 density is 37,000,000,000 Bq/m3 in retained water of reactor2 torus room, which is a part of the coolant system surrounding the vessel from the outside.

On the other hand, it is only 6,400,000,000 Bq/m3 in retained water of reactor2 vessel (PCV), which is just 17% of torus room.

Tepco is cooling the reactor2 on the assumption that the molten fuel is still in the vessel. However, this reading contradicts their theory.





You can ignore the truth but the truth won’t ignore you.

[Où est le combustible ?] La radioactivité du césium 134/137 est 6 fois plus élevée dans la salle du tore que dans l’enceinte du réacteur 2


Tepco publie des données sur la radioactivité des eaux à l’intérieur du réacteur.

Ce rapport a été remis au secrétariat du meeting sur le démantèlement de Fukushima du 29 août 2013.

Selon ces données, la radioactivité en Cs-134/137 est à 37 000 000 000 (37 milliards) Bq/m³ dans les eaux de la salle du tore du réacteur 2 qui font partie des eaux de refroidissement entourant l’enceinte depuis l’extérieur.
D’un autre côté, on n’a que 6 400 000 000 Bq/m³ (6,3 milliards) dans les eaux à l’intérieur de l’enceinte principale du réacteur 2 (PCV), soit seulement 17 % de la salle du tore.
Tepco refroidit le réacteur 2 sur l’hypothèse que le combustible fondu est toujours dans l’enceinte. Les relevés la contredisent.


Vous pouvez ignorer la vérité mais la vérité ne vous ignorera pas.

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.
