[Mystery] Reactor 3 trench water is extremely “salty”

Related to this article..36,000,000,000 Bq/m3 of Cs-134/137 measured from retained water of reactor2 trench / Tritium density under analysis [URL]

According to Tepco, the salinity concentration in the retained water in reactor3 trench is 157 times higher than the retained water in reactor2 trench.

The former is at 3.2m above the sea level. The latter is at 2.76 m above the sea level. The latter is more likely to have been affected by Tsunami but it’s less salty.

On 7/17/2013, Tepco collected the retained water in the cable trench of reactor2. Salinity concentration was 70 ppm.

On the other hand, the salinity concentration of the retained water in reactor3 trench vertical shaft was 11,000 ppm at the highest.

There is no other source of salinity but seawater.

Tepco hasn’t made any explanation about this significant gap of salinity concentration.

[Mystère] L’eau de la tranchée du réacteur 3 est extrêmement “salée”

 

Article lié : 36 milliards de Bq/m³ de Cs-134/137 dans les eaux retenues dans la tranchée du réacteur 2 / le tritium en cours d’analyse

Selon Tepco, la salinité de l’eau retenue dans la tranchée du réacteur 3 est 157 fois plus élevée que dans celle de la tranchée du réacteur 2.

La première est à 3,20 m au-dessus du niveau de la mer, l’autre en est à 2,76 m. La dernière a certainement été plus concernée par le tsunami et elle est pourtant moins salée.
Le 17 juillet 2013, Tepco a échantillonné les eaux retenues dans la tranchée de câblage du réacteur 2. La salinité était à 70 ppm.
De l’autre côté, La salinité des eaux retenues dans le puits vertical du réacteur 3 allait jusqu’à 11 000 ppm.
Il n’y a pas d’autre source de sel que la mer.
Tepco n’a donné aucune explication sur cette énorme différence de salinité.

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.
