Tepco to restart nitrogen gas injection into reactor1

According to Tepco, they are going to restart the nitrogen gas injection into the suppression chamber of reactor1 on 5/8/2013.

6~7m3/h will be injected in order to “push out the retained hydrogen gas” and also “look into the effect of radiolysis of water within suppression chamber”, which implies Tepco admits hydrogen gas is being produced from the radiolysis of water.

If the hydrogen gas density goes over 2%, there is a possibility of further hydrogen explosion.

They injected nitrogen gas only one month ago. There is a possibility that hydrogen gas is being constantly produced in reactor1.

Tepco relance les injections d’azote gazeux dans le réacteur 1

Selon Tepco, ils vont relancer les injection d’azote gazeux dans la salle en surpression du réacteur 1 à partir du 8 mai 2013.

6 à 7 m³/h seront injectés pour “pousser dehors l’hydrogène gazeux” et aussi “examiner l’effet de radiolyse de l’eau dans la salle en surpression”, ce qui implique que Tepco admet que de l’hydrogène gazeux est produit par la radiolyse de l’eau.
Si la densité de l’hydrogène gazeux dépasse 2 %, une autre explosion d’hydrogène devient possible.
Ils avaient injecté de l’azote il n’y a qu’un mois. Ils est probable que cet hydrogène soit produit dans le réacteur1 de façon constante.

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.
