Tepco injected nitrogen gas into reactor2 and 3 as well

On 10/23/2012, Fukushima Diary reported Tepco started injecting nitrogen gas into suppression chamber of reactor1 to avoid the risk of explosion. [Link]

According to Tepco’s report “Mid/long term roadmap of decommissioning Fukushima plant”,

Tepco has actually been injecting nitrogen gas into the pressure vessels of reactor1, 2 and 3 at least since10/21/2012. 

About reactor3, the nitrogen gas amount to inject is increasing, which was 16.86 Nm3/h on 10/21/2012 and 17.15 Nm3/h on 12/2/2012.

Tepco a injecté de l’azote gazeux dans les réacteurs 2 et 3 aussi

Le 23 octobre 2012, le Fukushima Diary avait rapporté que Tepco commençait à injecter de l’azote gazeux dans la salle de surpression du réacteur 1 pour parer au risque d’explosion. [Lien]

Selon le rapport de Tepco “Mid/long term roadmap of decommissioning Fukushima plant“,

Tepco a effectivement injecté de l’azote gazeux dans les enceintes pressurisées des réacteurs 1, et et 3 au moins depuis le 21 octobre 2012.

Pour le réacteur 3, le volume d’azote injecté a été augmenté, il était de 16,86 Nm³/h le 21 oct 2012 et de 17,15 Nm³/h le 2 dec 2012.

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.
