Former Fukushima worker, “β dose of the new leaking desalination system is up to 1~2 Sv/h.”

Following up this article..New leakage from desalination system, 26 giga Bq/m3 of all β, Tepco, “250L, no overflow from the warehouse” [URL]

The former Fukushima worker Happy11311 commented on twitter the leaking system is severely contaminated.



The leakage of the desalination system used to happen frequently when I was there. It depends on the leaking part, but I think the β dose is really high. Usually it’s about 300 ~ 500 mSv/h. It can be 1 ~ 2 Sv/h. ・・・




Fukushima Diary plans to research Svalbard as a temporary / permanent shelter. It will be in one month from now but there is least budget now. The planned term is 2 weeks. The estimate is 5,000 €. It would be a great help if you consider supporting it.
Thank you.

L’ancien travailleur de Fukushima Happy11311 déclare sur Twitter que le système qui fuit est gravement contaminé :

Il y avait souvent des fuites dans le système de désalinisation quand j’y étais. Ça dépend de l’endroit de la fuite mais je pense que la dose en β est vraiment grave. D’habitude c’est autour de 300 ~ 500 mSv/h. Là, ça doit aller jusqu’à 1 ~ 2 Sv/h. ・・・

Le Fukushima Diary prévoit de faire des recherches à Svalbard en tant que refuge provisoire/ permanent. Ce sera dans un mois mais l’argent manque actuellement . C’est prévu sur 2 semaines. L’estimation porte sur 5 000 €. Votre soutien serait d’une grande aide.

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.
