Tepco to restart nitrogen gas injection into reactor1 again

From 2/26/2013, Tepco is going to restart injecting nitrogen gas into S/C of reactor1. (5m3/h)

S/C is a part of PCV. If the hydrogen gas density goes over 2%, there is a possibility of further hydrogen explosion.

Tepco still needs to inject nitrogen gas into PCV to push out hydrogen gas out of PCV.

Tepco va encore relancer les injections d’azote gazeux dans le réacteur 1


A partir du 26 février 2013, Tepco va recommencer ses injections d’azote gazeux dans la S/C du réacteur 1. (5 m³/h)

La S/C (= salle en surpression) fait partie de la PCV (= enceinte de confinement primaire). Si la concentration d’hydrogène y dépasse 2 %, le risque d’explosion d’hydrogène devient possible.

Tepco a toujours besoin d’injecter de l’azote gazeux dans la PCV pour en pousser l’hydrogène au dehors.


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.
