Tritium density continuously increasing upstream of groundwater bypass wells since October of 2013

Tritium density in groundwater has been constantly increasing since October of 2013, according to Tepco.

The graph below published by Tepco shows the increasing trend but it is not entirely clear because the density is represented logarithmically.


The sampling location is upstream of groundwater bypass wells. Tepco plans to discharge the water pumped up from those wells, and Tritium can’t be filtered out.

Tepco hasn’t made any announcement about the increasing trend and the reason is not identified.

Depuis octobre 2013, la radioactivité en tritium augmente continuellement en amont des forages de dérivation

Selon Tepco, la radioactivité en tritium des eaux souterraines a continuellement augmenté depuis octobre 2013.
Le graphique ci-dessous publié par Tepco montre la tendance à l’augmentation mais ce n’est pas parfaitement évident parce que l’échelle des concentrations utilisée est logarithmique.

L’endroit échantillonné est en amont des puits de la dérivation des eaux souterraines . Tepco prévoit de déverser directement en mer l’eau pompée de ces puits et le tritium ne peut pas en être filtré.
Tepco n’a fait aucun communiqué sur cette augmentation continue et sa cause n’en est pas déterminée.

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.
