2,200,000,000,000 Bq of All β nuclides leaked to the Pacific in the recent 314 days

On 3/25/2015, Tepco reported to NRA (Nuclear Regulation Authority) that 2,200,000,000,000 Bq of All β nuclide (including Strontium-90) leaked from the plant area to the plant port in the recent 314 days.

The term is from 4/16/2014 to 2/23/2015.

Regarding Tritium, 4,800,000,000,000 Bq leaked to the port, Tepco reported.

These nuclides are contained in groundwater from the plant area. Tepco cannot complete building the underground wall to to separate the land and port because the wall would cause groundwater overflow in the plant area.


They announced approx. 10% of the same amounts directly flowed to the Pacific, outside of the plant port.

Sur ces 314 derniers jours, 2 200 milliards de Bq de radioactivité β ont fuit dans le Pacifique


Le 25 mars 2015, Tepco rapporte à la NRA (Nuclear Regulation Authority) que 2 200 000 000 000 Bq (2 200 milliards) de radioactivité β (dont le strontium 90) ont, sur ces derniers 314 jours,  fuit de la centrale dans son port.

La période est celle du 16 avril 2014 au 23 février 2015.
Concernant le tritium, 4 800 000 000 000 Bq (4 800 milliards) en ont fuit dans le port, rapporte Tepco.
Ces nucléides sont dans les eaux souterraines de la centrale. Tepco ne peut pas terminer la construction des murs souterrains pour couper la terre du port parce que les murs provoqueraient l’inondation de la centrale par les eaux souterraines.

Ils ont déclaré qu’environ 10% de ces quantités sont directement parties dans le Pacifique sans passer par le port de la centrale.


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.
