[Concealed explosion at reactor2?] D/W pressure jumped up twice on 3/16/2011

On 11/19/2012, Fukushima Diary reported Tepco may be hiding unknown explosion occurred on 3/16/2011. [Link]

The next day, 11/20/2012, Tepco quietly released the missing data, which was the D/W (Dry well) pressure of reactor2 at 1:35 and 12:25 of 3/16/2011.

The newly released data shows the D/W pressure jumped up twice on 3/16/2011.

Reactor water level, ambient dose of D/W and suppression chamber are still missing for some reason.

According to Tepco, reactor2 did not explode after 311 supposedly but the sharp increase of the pressure in D/W suggests a hidden accident happened in PCV of reactor2.

[Explosion censurée du réacteur 2 ?] la pression de l’enceinte sèche a sauté deux fois le 16 mars 2011

Le 19 novembre 2012, le Fukushima Diary a rapporté que Tepco a pu cacher qu’une explosion a eu lieu le 16 mars 2011. [Lien]

Le jour suivant, le 20 novembre 2012, Tepco publie tranquillement les données manquantes, celles de la pression de l’enceinte sèche (= D/W = Dry well) du réacteur 2 du 16 mars 2011 à 1:35 et à 12:25.

Ces données nouvellement publiées montrent que la pression dans la D/W a fait deux pics ce 16 mars 2011.

Le niveau d’eau du réacteur, la dose ambiante dans la D/W et dans la chambre de surpression sont toujours manquantes.

Selon Tepco, le réacteur 2 n’a soi-disant pas explosé après le 11-3 mais la montée brutale de la pression dans la D/W suggère qu’un accident a bien eu lieu dans la PCV2 (enceinte de confinement du réacteur 2).

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.
