Following up this article.. Tepco “Analysis data is checked by someone in charge before publishing” [URL]


Tepco actually found the fact that they had been analyzing Strontium-90 in the wrong manner out on 10/2/2013. Tepco stated in the press conference of 2/10/2014.

However they didn’t announce that until last week.


NRA (Nuclear Regulation Authority) realized the randomness in Tepco’s measurement result by August. They sent the inspectors to the laboratory of Tepco on 10/8/2013, but they didn’t find anything to prove that Tepco has been analyzing in the wrong matter because Tepco changed it 6 days before.

It is not clear if Tepco intentionally covered up their wrong analysis before NRA came.

There is a possibility that the actual accident evaluation will be raised from now as Tepco gradually reveals the facts that they have been concealing since 311.

Tepco savait que ses analyses du strontium 90 étaient fausses dès le 2 octobre 2013, 6 jours avant que la NRA envoie ses inspecteurs

Tepco avait découvert en fait qu’ils se trompaient dans leurs analyses du strontium 90 dès le 2 octobre 2013. Tepco l’a affirmé au cours de la conférence de presse du 10 février 2014.
Ils ne l’ont néanmoins pas rendu public avant la semaine dernière.

La NRA (Nuclear Regulation Authority) avait réalisé le caractère aléatoire des relevés de Tepco courant août. Ils avaient envoyé leurs inspecteurs au laboratoire de Tepco le 8 octobre 2013 mais ils n’avaient rien pu trouver pour prouver que Tepco suivait une mauvaise méthode parce que Tepco en avait changé 6 jours plus tôt.
On ne sait pas si Tepco a intentionnellement caché leurs erreurs d’analyse avant que la NRA arrive.
Il est possible que l’évaluation de l’accident réel soit augmentée à partir de maintenant au fur et à mesure que Tepco révèle les faits qu’ils censurent depuis le 11-3.

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.
