[Out of control] Tepco admitted another contaminated water reservoir leaking as well

On 4/6/2013, Fukushima Diary suggested the possibility that another contaminated water reservoir (No.3) is also leaking water.

(cf, [Leakage] Density of beta nuclide increased by 17%, radiation detected from 2 more reservoirs [URL])

On 4/7/2013, Tepco admitted No.3 reservoir is also leaking the contaminated water.

From the detection drain of the south west side in No.3, they measured 1.8×10^9 Bq/m3 of β nuclide and 350 ppm chloride concentration at 22:20 4/6/2013.

5 hours later, it picked up to be 2.2×10^9 Bq/m3 of β nuclide and 380 ppm chloride concentration at 3:45 4/7/2013.

Tepco comments the water level doesn’t show a significant change, they assume it’s not a large leakage. They are not planning to transfer the water to other reservoirs.

However, there’s a possibility that rain water is being flowing into the reservoir now.

[Perte de contrôle] Tepco admet qu’une autre cuve d’eaux contaminées fuit aussi


Le 6 avril 2013, le Fukushima Diary suggérait la possibilité qu’un autre réservoir d’eau contaminée (No.3) fuyait aussi. (cf. [Fuites] La concentration en bêta nucléides a augmenté de 17 %, de la radioactivité détectée sur 2 autres réservoirs)

Le 7 avril 2013, Tepco admet que le réservoir N°3 perd aussi son eau contaminée.
Leur détection du 6 avril 2013 à 22:20 des évacuations du sud-ouest du N°3 relève 1 800 000 000 Bq/m³ de β-nucléides et 350 ppm de chlorures.
5 heures plus tard, à 03:45 ce même 7 avril 2013, c’est monté à 2 200 000 000 Bq/m³ de β-nucléides et 380 ppm de chlorures.
Tepco déclare que le niveau d’eau ne présente pas de changement significatif, ils pensent que ce n’est pas une grosse fuite.
Ils ne prévoient pas de transférer cette eau dans d’autres réservoirs.

Il est cependant possible que l’eau de pluie s’infiltre dans ce réservoir à présent.

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.
