Water leakage from air-conditioning duct of reactor4, Tepco”It’s rain water, not from SFP”
On 12/13/2012, Tepco found water leaking from air-conditioning duct of the reactor4 disposal building of radioactive waste.
Tepco immediately denied the possibility that the water is from SFP because it doesn’t include cobalt-60 and hydrazine.
In SFP of reactor4, 2.5E+5 Bq/m3 of cobalt-60 and 3ppm of hydrazine are supposed to be contained.
Tepco states it’s rain water but it contains 4.2E+7 Bq/m3 of Cs-134 and 7.2E+7 Bq/m3 of Cs-137.
Le 13 décembre 2012, Tepco a trouvé une fuite d’eau à partir d’un tuyau d’air conditionné dans le bâtiment des déchets radioactifs du réacteur 4.
Tepco a immédiatement nié toute possibilité que ce soit de l’eau de la SFP (pîscine des combustibles) parce qu’il n’y a ni cobalt-60, ni hydrazine dedans.
Dans la SFP du réacteur 4 il est supposé y avoir 250 000 Bq/m³ de cobalt-60 et 3 ppm d’hydrazine.
Tepco affirme que c’est de l’eau de pluie mais elle est à 42 000 000 Bq/m³ de Cs-134 et 72 000 000Bq/m³ de Cs-137.
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.
