Tepco trying to stop 30,000,000 Bq/m3 of Cs-134/137 water with sandbag and blue sheeting

Following up this article.. 29,400,000 Bq/m3 of Cs-134/137 from water on the roof of Reactor 2 / kept flowing to the Pacific for 4 years [URL]

 

At this moment, Tepco has nothing better than sandbag and blue sheeting to stop extremely contaminated water flowing to the sea, Tepco reported on 3/2/2015.

It is the water that they detected 29,400,000 Bq/m3 of Cs-134/137 from.

According to Tepco, they installed sandbags at TWO drainage outlets on 2/27/2014. On 3/2/2015, they covered the roof with blue sheeting. The superposing section was even taped.

It is not announced how they plan to drain rainwater retained on the blue sheeting.

 

Tepco states even though the sandbag contains zeolite, it is a provisional measure. They plan to remove the main contamination source but it has not been identified yet.

The roof of the main part of Reactor 2 building has not been investigated due to the excessively high level of radiation.

Tepco essaye de stopper 30 millions de Bq/m³ de césium 134/137 d’eau avec des sacs de sable et des feuilles de plastique

Tepco rapporte le 2 mars 2015 que pour l’instant, ils n’ont rien de mieux que des sacs de sable et des feuilles de plastique bleu pour bloquer les eaux extrêmement radioactives s’écoulant vers la mer.
Il s’agit des eaux où ils avaient relevé 29,4 millions de Bq/m³ de Cs 134/137.
Selon Tepco, le 27 février 2015 ils ont installé des sacs de sable à DEUX déversoirs. Le 2 mars 2015, ils ont couvert le toit de feuilles bleues. Les zones de jointure ont même été scotchées.
Ils ne disent pas comment ils prévoient d’évacuer les eaux retenues sur les feuilles de plastique.

Tepco affirme que même si les sacs sont remplis de zéolite, c’est une solution provisoire. Ils prévoient d’éliminer la principale source de contamination mais elle n’est pas encore connue.
La majeure partie du toit du bâtiment du réacteur 2 n’a pas été examinée à cause de sa radioactivité trop élevée.

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.
