875,000,000,000,000 Bq of Tritium contained in total contaminated water / Over 60 times much as safety limit

Following up this article.. [Column] Contaminated water will be discharged to the Pacific [URL]


The total volume of Tritium contained in the stocked contaminated water is 875 trillion Bq. Tepco submitted the data to Tritium task force of Ministry of Economy, Trade and Industry.

Currently 400,000 tonnes of contaminated water is stocked in the tanks. 817 trillion Bq of Tritium is contained in it.

Additionally contaminated water is also stocked in reactor buildings etc.. The part of contaminated water outside of the tanks contain 58 trillion Bq of Tritium.

Tritium is not going to be filtered.

This is 59 times much as the annual safety limit of 4 reactors to discharge to the sea. This means, they would take over 59 years to resolve the current water problem even if they choose to discharge it to the sea. In reality, the volume of contaminated water is increasing by over 400m3 per day.





Thank you for reading Fukushima Diary. Your support is the energy of my restless work.

Le volume total de tritium contenu dans les eaux extrêmement radioactives est de 875 trilliards de Bq. Tepco a transmit ces données au groupe de travail du ministère de l’Économie, du Commerce et de l’Industrie.

Actuellement, les citernes contiennent 400 000 tonnes d’eau extrêmement radioactive. On a 817 trilliards de Bq de tritium dedans.
D’autres eaux extrêmement radioactives sont stockées aussi dans les bâtiments des réacteurs, etc. La portion qui n’est pas en citernes représente 58 trilliards de Bq de tritium.
Le tritium ne sera pas filtré.
C’est, pour les 4 réacteurs, 59 fois la limite annuelle autorisée pour les déversements en mer. Ça signifie qu’il leur faudra plus de 59 ans pour résoudre le problème actuel avec ces eaux même s’ils choisissent de les déverser en mer. En réalité, le volume des eaux extrêmement radioactives augmente de plus de 400 m³ par jour.

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.
