Tepco decided to continue using the bypass well that exceeding level of Tritium was measured from

Following up this article.. Tritium density exceeded the safety limit at one of the bypass wells one day after they discharged 1,600 t to the sea [URL]


On 6/12/2014, Tepco announced that they are going to keep using the bypass well that they detected the exceeding density Tritium.

In that well, Tritium density increased from 1,100,000 Bq/m3 to 1,700,000 Bq/m3 since the end of May. From Tepco’s own simulation, it is assumed to jump up to 2,300,000 Bq/m3 where the desired safety limit is 1,500,000 Bq/m3.


Tepco states the volume of water from this well is only 7% of total. Even if they continue pumping up water from this well, the average Tritium density would be 231,800 Bq/m3 because they mix it up with less contaminated water.


At 19:20 of 6/12/2014, Tepco restarted pumping up contaminated water from this well to discharge to the sea.

Tepco décide de continuer d’utiliser le puits de dérivation qui dépasse la limite en tritium

Le 12 juin 2014, Tepco annonce qu’ils vont continuer d’utiliser le puits de dérivation dans lequel ils avaient relevé une radioactivité en tritium supérieure à leur limite de sécurité.
Dans ce forage, la radioactivité en tritium est passée de 1,1 à 1,7 millions de Bq/m³ depuis la fin du mois de mai. Selon les propres simulations de Tepco, on suppose que ça va monter à 2,3 millions de Bq/m³ alors que la limite de sécurité désirée est de 1,5 millions de Bq/m³.

Tepco affirme que le volume d’eau de ce puits ne représente que 7 % du total. Même en continuant de pomper l’eau de ce puits et parce qu’ils la mélangent avec des eaux moins radioactives, la moyenne de la radioactivité en tritium sera de 231 800 Bq/m³.

Le 12 juin 2014 à 19:20, Tepco a relancé le pompage de l’eau radioactive de ce puits pour la balancer en mer.

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.
