Tepco’s own data shows filtration system cannot remove Tritium from potentially discharged water at all

Following up this article.. Tepco to pump up highly contaminated groundwater for potential discharge today / Drainage plan submitted to NRA [URL]


Tepco’s filtration system does not remove Tritium at all. Tepco admitted this on their report published this August and October.

They are planning to discharge the highly contaminated groundwater pumped up just beside the crippled reactor buildings.

From their analysis, Tritium density was 660,000 Bq/m3 in the unfiltered water, and it remained to be 670,000 Bq/m3 even after the “filtration”.


Tepco states 47 other nuclides can be reduced to be 1/1,500 level, however this is only based on their subjective analysis.

Les propres données de Tepco montrent que le système de filtration ne peut pas filtrer le tritium des eaux déversées en mer

Le système de filtration de Tepco ne filtre pas du tout le tritium. Tepco le reconnaît dans ses rapports publiés en août et en octobre.
Ils prévoient de déverser en mer les eaux souterraines extrêmement radioactives pompées juste à côté des bâtiments des réacteurs dévastés.
Selon leurs analyses, la radioactivité en tritium était de 660 000 Bq/m³ dans les eaux non-filtrées et elle est restée à 670 000 Bq/m³ même après “filtration”.

Tepco affirme que 47 autres nucléides sont réduits par un facteur de 1 500, néanmoins ce n’est affirmé que sur une base subjective.


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.
