Radioactivity density of sub-drain in reactor1 remaining in high level

On 3/7/2013, Fukushima Diary reported “Radiation level in sub-drain of reactor1 and 2 picking up [URL]”

According to Tepco, the radioactivity density is still staying high.

(When you look at the trend in the graph below, you should be careful about the divisions. It’s 1.0, 10.0, 100.0, 1000.0,, the divisions are not equalized.)

La radioactivité des évacuations du réacteur 1 reste à un haut niveau élevé


Le 7 mars 2013, le Fukushima Diary rapportait Le niveau de radioactivité des canalisations d’évacuation des réacteurs 1 et 2 ré-augmente
Selon Tepco, la radioactivité reste toujours élevée.

(Lorsqu’on examine la tendance dans le graphique suivant, on doit faire attention à l’échelle. C’est 1, 10, 100, 1000, les divisions ne sont pas linéaires mais arithmétiques.)

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.
