Hydrogen concentration in reactor1 is increasing

According to plant parameter released by Tepco, hydrogen concentration in PCV of reactor1 is increasing since 5AM of 12/8/2012.

At 9:10 of 12/7/2012, Tepco restarted the nitrogen gas injection into suppression chamber of reactor1 but the connection is unknown. [Link]

La concentration en hydrogène du réacteur 1 augmente

Selon les paramètres usine publiés par Tepco, la concentration en hydrogène de la PCV (enceinte de confinement primaire) du réacteur 1 augmente depuis le 8 décembre 2012 à 05:00.

La veille à 9:10, Tepco avait relancé les injections d’azote gazeux dans la chambre en surpression du réacteur 1 mais il n’y a pas de lien connu entre ces deux faits. [Lien]

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.
