Rising Tritium level in Bypass water / Became the highest density again

On 6/25/2014, Fukushima Diary reported the Tritium density reached the highest level in one of the bypass wells.


Tritium density reached the highest in one of the bypass wells again / Already double as one month ago [URL]

From Tepco’s report on 6/25/2014, the Tritium density from the issued bypass well became the highest since they started measuring again.

The sample was taken on 6/23/2014. The reading was 2,100,000 Bq/m3. This is over the desired safety limit by 600,000 Bq/m3.

Tepco is still stating that the average Tritium density will be lower by mixing with lower contaminated water.


However based on the research of Fukushima Diary, the Tritium density is in the increasing trend since the end of May. Now it’s already 1.9 much of one month ago.


On 7/2/2014, Tepco announced they measured even higher density of Tritium from the issued well.

The reading was 2,300,000 Bq/m3. It was higher than the last highest reading by 200,000 Bq/m3. The sampling date was 6/30/2014.


Since the end of May, it has been in the increasing trend. At the moment of 6/30/2014, it’s already 2.1 times much as the reading of 5/22/2014.

Tepco has made no explanation about the potential cause of the increasing Tritium density.

Le tritium augmente encore dans la dérivation : un nouveau record


Le 25 juin 2014, le Fukushima Diary rapportait que la radioactivité en tritium avait atteint un record dans l’un des puits de forage de la dérivation :

La radioactivité en tritium atteint un nouveau record dans l’un des puits de la dérivation / déjà double du mois dernier

Selon un rapport de Tepco du 25 juin 2014, la radioactivité en tritium du fameux puits est en record depuis qu’ils ont repris sa mesure.
L’échantillon est du 23 juin 2014. Le relevé, de 2 100 000 (2,1 millions de) Bq/m³. C’est au-delà, de 600 000 Bq/m³, de leur limite de sécurité.
Tepco continue d’affirmer que la radioactivité moyenne en tritium restera plus faible en la mélangeant avec des eaux moins radioactives. Néanmoins, en se basant sur les recherches du Fukushima Diary, la radioactivité du tritium augmente continuellement depuis fin mai. A présent elle est déjà à 190% de ce qu’elle était il y a un mois.

Ce 2 juillet 2014, Tepco annonce qu’ils ont relevé encore plus de radioactivité en tritium dans le puits en question.
Le relevé est de 2 300 000 (2,3 millions de) Bq/m³. C’est plus radioactif de 200 000 Bq/m³ que le dernier relevé. L’échantillonnage est du 30 juin 2014.

Ça augmente depuis fin mai. Au 30 juin 2014, on est déjà à 210% du relevé du 22 mai 2014.
Tepco n’a fourni aucune hypothèse probable sur cette augmentation de la radioactivité en tritium.

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.
