550,000 Bq/m3 of Cs-134/137 measured outside of the impervious wall / Contaminated water overflowing the wall

According to Tepco, high level of Cesium-134/137 was detected outside of the impervious wall, where is only 2m from the sea.

Tepco built the underground wall on the coastal line of reactor2 in order to stop contaminated groundwater flowing to the Pacific.

It caused the unexpected side effect as the rising groundwater level inside of the wall, so Tepco also had to pump up the water.

Regardless of all the costs and the exposure of the workers, it turned out that the wall doesn’t stop the contaminated groundwater that they detected high level of Cs-134/137 outside of the wall.

The readings were 170,000 Bq/m3 of Cs-134 and 380,000 Bq/m3 of Cs-137. This is 7~15 times much as the near seawater.

Tepco filtered the water because “impurities were found in the sample”, but Cs-134/137 reading was still 186,000 Bq/m3.








You can ignore the truth but the truth won’t ignore you.

550 000 Bq/m³ de césium à l’extérieur du mur étanche : Les eaux extrêmement radioactives débordent par dessus le mur


Selon Tepco, une haute radioactivité en césium 134/137 a été relevée à l’extérieur du mur étanche qui n’est qu’à 2 m de la mer.

Tepco avait construit ce mur étanche le long du rivage du réacteur 2 pour empêcher la contamination souterraine de rejoindre le Pacifique.
Ça a provoqué l’effet de bord imprévu de faire remonter les eaux souterraines du côté interne de ce mur, alors Tepco a aussi décidé de les pomper.
Indépendamment des coûts et de l’exposition de travailleurs, ce mur se révèle incapable de contenir les eaux souterraines puisqu’ils relèvent autant de Cs-134/137 de l’autre côté du mur.
Les relevés sont de 170 000 Bq/m³ de Cs 134 et 380 000 Bq/m³ de Cs 137. C’est entre 7 et 15 dois plus que ce qu’on a à proximité dans l’eau de mer.
Tepco a filtré les eaux parce que “on avait trouvé des impuretés dans l’échantillon” mais le relevé du Cs 134/137 est resté à 186 000 Bq/m³.

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.
