[Video] Tepco started discharging contaminated groundwater beside crippled reactor buildings

Following up this article.. Fukushima fishing cooperative allowed Tepco to discharge the contaminated groundwater to the sea [URL]

 

Tepco started discharging the contaminated groundwater to the Pacific on 9/14/2015, Tepco reported.

It was discharged for nearly 6 hours in daytime. The reported volume of contaminated water was 838 t.

The discharged water was pumped up from 20 of 41 wells called “sub-drain” situated beside crippled reactor buildings 1 ~ 4.

10,800,000 Bq/m3 of Cs-134/137 and 16,000,000 Bq/m3 of Tritium were measured from the water pumped this August. Tepco announced they purified water before discharging, however unremovable nuclide Tritium still remains in water. 390,000 ~ 600,000 Bq/m3 of Tritium was detected from “filtered” water from third party organization’s analysis.

Tepco rapporte avoir commencé ce 14 septembre 2015 à déverser dans le Pacifique les eaux souterraines extrêmement radioactives .

Ils en ont déversé pendant près de six heures pendant la journée. Le volume déclaré d’eau extrêmement radioactive est de 838 T.
L’eau déversée a été pompée à partir de 20 des 41 puits dits «sous-drain” situés à côté des bâtiments dévastés des réacteurs 1 à 4.
En août, on relevait 10 800 000 Bq/m³ de Cs 134/137 et 16 000 000 Bq/m³ de tritium dans les eaux pompées. Tepco a déclaré avoir purifié l’eau avant de la déverser, cependant l’infiltrable tritium reste dans ces eaux.
Selon l’analyse d’une entreprise tierce, de 390 000 à 600 000 Bq/m³ de tritium ont été relevés dans les eaux “filtrées”.

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.
