[100m3 leakage] Someone possibly turned on the wrong valve for malicious purpose

Following up this article.. 100m3 of highly contaminated water overflowed from a tank / 24,000,000,000,000 Bq of All β nuclides leaked [URL]


The leakage might have been caused due to the malicious operation of the valve, according to Tepco.

In the press conference of 2/21/2014, Tepco announced a pump sent contaminated water to a wrong tank up to over capacity, which ended up causing the overflow.

The pump was supposed to send the water to another tank, but the wrong valve of the pipe was turned on and another wrong valve was turned off to lead the water in the wrong direction.

Tepco found this out from the valve photos taken on 2/19/2014 for irrelevant purpose.

From those photos, the water level gauge of the overflowed tank started indicating abnormality when the wrong valve was turned on and another one was turned off. However strangely, when Tepco employees went to the overflowing tank area in order to settle it down, the valves were fixed. Someone must have touched the 2 valves when not recognized. Those photos even caught a lever remaining on the valve, but the workers who took the photos didn’t know what it meant.


At the moment of 2/21/2014, Tepco was still interrogating the relevant workers. However nobody was supposed to operate the valves during the issued time, so it’s hard to assume someone touched the valves by mistake.






Downplay it in the beginning, and quietly add more information so nobody notices it. All for not letting the cattle escape. This is their strategy.

[fuite des 100 m³] Quelqu’un a changé les vannes exprès

Selon Tepco, la fuite est peut-être due à une opération malveillante des vannes.

Au cours de la conférence de presse du 21 février 2014, Tepco a annoncé qu’une pompe a envoyé de l’eau extrêmement radioactive vers une mauvaise citerne jusqu’à la faire déborder.
La pompe était supposée envoyer l’eau dans une autre citerne mais une mauvaise vanne était ouverte sur le tuyau et une autre était fermée ce qui envoyait l’eau dans une mauvaise direction.
Tepco l’a découvert à partir de photos des vannes prises le 19 février 2014 pour autre chose.
Sur ces photos, la jauge de niveau d’eau de la citerne qui a débordé a commencé à indiquer une anomalie lorsque la mauvaise vanne a été ouverte et l’autre fermée. Or, de façon étrange, lorsque les employés de Tepco sont allés dans la zone de la citerne en débordement  pour le corriger, les vannes étaient déjà corrigées. Quelqu’un a forcément touché à ces 2 vannes sans se faire connaître. Ces photos ont même pris un niveau à bulle resté à côté d’une vanne mais ceux qui ont pris les photos ne savaient pas ce que ça pouvait dire.

Au 21 février 2014, Tepco interrogeait toujours les travailleurs impliqués. Or, aucun d’eux n’a été supposé toucher aux vannes pendant la période en question, il est donc difficile de croire qu’on ait modifié ces vannes par erreur.


Le minimiser au début et ajouter tranquillement de nouvelles information pour que personne ne le remarque. Tout pour que le troupeau ne s’échappe pas. C’est leur stratégie.

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.
