Tepco stocking contaminated water in the leaking reservoir No.1 again, Tepco “diluting”

In order to control the increasing contaminated water, Tepco tried to stock contaminated water in 7 reservoirs.

However, since they found the leakage from those reservoirs this April, Tepco have transferred it to spare tanks again.

On 6/12/2013, Fukushima Diary reported the radiation level of the leakage detector hole of the “nearly empty” reservoir is not decreasing having declared all the water was transferred.

(cf, Radiation level increasing in leakage detector hole of “nearly empty” reservoir No.1 [URL])

According to Tepco, they are starting to stock contaminated water to the reservoir No.1 again since 6/19/2013 in order to “dilute” the retained water.

They state the newly stocked water is processed by desalination system, which contains “only” 10,000,000 Bq/m3 of all β nuclides.

The retained water contains 66,000,000,000 Bq/m3 of all β nuclides.

They transferred 24m3 on 6/19/2013, 16m3 on 6/20 to the leaking reservoir No.1. Tepco states they are going to transfer the newly added water to another temporary tank on 6/21/2013. They will continue to “dilute” retained water by early July.

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.

Tepco recommence son stockage d’eaux extrêmement radioactives dans le réservoir percé n°1, Tepco : ” pour diluer”

 

Tepco avait essayé de stocker les eaux extrêmement radioactives dans 7 réservoirs en gestion de leurs quantités croissantes.

Cependant, depuis qu’ils leurs ont découvert des fuites en avril dernier, Tepco les transvase à nouveau dans les citernes disponibles.
Le 12 juin 2013, le Fukushima Diary publiait La radioactivité augmente dans le trou de détection des fuites du réservoir 1 “pratiquement vide”
Selon Tepco, ils ont recommencé à en transvaser dans ce réservoir n°1 depuis le 19 juin 2013, pour “diluer” les eaux qui y sont encore.
Ils affirment que l’eau ajoutée est traitée par le système de désalinisation qui ne titre “que” à 10 000 000 Bq/m³ pour l’ensemble des β nucléides (10 millions).
Les eaux résiduelles du réservoir 1 titrent à 66 000 000 000 Bq/m³ de β nucléides (66 milliards).
Dans ce réservoir percé n°1, ils ont transvasé 24 m³ le 19 et 16 m³ le 20 juin 2013. Tepco affirme qu’ils vont re-transvaser l’eau ajoutée dans une autre citerne provisoire dès le 21 juin 2013. Ils recommenceront à “diluer” ces eaux résiduelles début juillet.

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.
Merci.

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.
