The radioactive density of SFP of reactor 1 is 24 billion Bq/m3, 5266 times much as reactor4

From the power blackout since 18:57 of 3/18/2013, the coolant system of the spent fuel pool of reactor1, 3 and 4 have been stopped.

(cf, [Breaking] Power blackout in Fukushima plant, coolant system of the pools in reactor 1,3,4 lost power [URL])

According to Tepco, the pool water of reactor1 is extremely contaminated compared to other 3 spent fuel pools, which is 5266 times worse than the spent fuel pool of reactor4.

Le niveau de radioactivité de la SFP1 est de 24 milliards de Bq/m³, 5266 fois plus que la SFP4

 

Depuis la coupure de courant du 18 mars 2013 à 18:57, les systèmes de refroidissement des piscines à combustibles usagés (SFP) des réacteurs 1, 3 et 4 sont arrêtés. (cf. [Breaking] Panne de courant dans la centrale de Fukushima, le système de refroidissement des piscines des réacteurs 1,3 et 4 n’ont plus de courant)

Selon Tepco, la piscine du réacteur 1 est extrêmement contaminée par rapport aux 3 autres SFPs, 5 266 fois plus que la SFP4.

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.
