2,029,900,000 Bq of Cs-134/137 leaked as contaminated water in Fukushima plant

According to Tepco, a leakage detector of waste incineration building went off around noon of 3/23/2016.

Tepco reports the leaked volume was 5.3 t. The leaked contaminated water was from the cesium absorption facility to contain extremely high density of Cs-134/137.

From Tepco’s announcement, Cs-134/137 density was 383,000,000 Bq/m3.

All β nuclides to include Sr-90 was 480,000,000 Bq/m3.

At the moment of the press release, Tepco had not completed removing the leaked water but they state the building is designed to retain contaminated water inside.

The pipe from the cesium absorption facility was cut off due to a construction however somebody turned on the facility to cause the large leakage.

Fuite de 2 029 900 000 Bq de Cs-134/137 d’eau extrêmement radioactive dans la centrale nucléaire de Fukushima


Selon Tepco, le 23 mars 2016 un détecteur de fuite du bâtiment d’incinération des déchets s’est déclenché vers midi.

Tepco rapporte un volume de fuite de 5,3 T. L’eau extrêmement radioactive de la fuite provient de l’appareillage d’absorption du césium qui contient des concentrations extrêmement élevées en Cs-134/137.
Selon le communiqué de Tepco, la radioactivité en Cs-134/137 y est de 383 000 000 Bq/m³ (383 millions). Celle des β-nucléides dont le Sr-90, de 480 000 000 Bq/m³ (480 millions).

Au moment du communiqué de presse, Tepco n’avait pas fini de récupérer les eaux de la fuite mais ils affirment que le bâtiment est construit pour les retenir à l’intérieur.
Le tuyau de l’appareil d’absorption du césium a été sectionné à cause d’une construction et quelqu’un a mis en marche l’appareil, ce qui a provoqué la fuite.


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.
