Tepco failed in purifying all the contaminated water by deadline

Following up this article.. Tepco decided to break their promise with Abe to purify all contaminated water by this April [URL]

 

On 5/27/2015, Tepco announced they could not purify 29% of the stocked contaminated water. Tritium has not been removed at all.

Tepco ended up prolonging the deadline by 2 months. However, ALPS (Advanced Liquid Processing System) purified only 440,000 m3 of 620,000 m3 and 180,000 m3 remained un-purified.

Tepco insists they removed Cs-134/137 and Sr-90 from the remaining 180,000 m3, so it can be said all the contaminated water has been purified.

 

Groundwater still flows into the basement of the plant buildings to be mixed with highly contaminated water, which is causing additional 400 m3 contaminated water everyday.

Tepco n’est pas arrivé à filtrer toutes les eaux extrêmement radioactives dans le temps imparti

Le 27 mai 2015, Tepco a annoncé ne pas avoir pu purifier 29 % des eaux extrêmement radioactives stockées. Le tritium n’en a pas du tout été traité.

Tepco en avait fini par repousser l’échéance de 2 mois. Néanmoins, le système ALPS (Advanced Liquid Processing System) n’a “purifié” que 440 000 des 620 000 m³, il en reste 180 000 m³ en l’état.
Tepco insiste sur le fait que dans les 180 000 m³ restants le filtrage des Cs 134/137 et Sr 90 est fait, donc ils se sentent autorisés à dire que toutes les eaux extrêmement radioactives sont purifiées.

Des eaux souterraines s’infiltrent toujours dans les fondations des bâtiments de la centrale, se mélangeant ainsi à des eaux extrêmement radioactives. Ceci ajoute 400 m³ d’eaux extrêmement radioactives de plus chaque 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.
