Reactor3 coolant water leakage → 1/3 of injected water was leaking / Tepco doesn’t know when it started

Following up this article.. [Video] Possible direct leakage of reactor3 coolant water to the building [URL]

 

1.5 m3/h of possible coolant water was directly leaking from the PCV (Primary Containment Vessel) of reactor3, according to Tepco.

They inject 5.5 m3 of coolant water per hour. This means approx. 27% of the coolant water was leaking out of the vessel.

 

Tepco also stated they got to see the leakage because they removed the debris, so they don’t know since when it has been leaking.

It is reported that the volume of leakage significantly decreased on 1/21/2014, however it is not known what caused the change of volume, such as because the molten fuel moved inside of PCV.

Fuite du liquide de refroidissement du réacteur 3  → 1/3 de ce qui était injecté / Tepco ne sais pas depuis quand

Selon Tepco, 1,5 m3/h de liquide de refroidissement a du fuir directement de la PCV3 (Enceinte de Confinement Primaire du réacteur 3).
Ils en injectent 5,5 m3 par heure. Ça signifie que environ 27 % du liquide de refroidissement sortait de l’enceinte.

Tepco a aussi affirmé qu’ils avaient remarqué la fuite pendant qu’ils enlevaient les gravas, alors ils ne savent pas depuis quand ça fuit.
Il est rapporté que le volume de la fuite a grandement diminué depuis le 21 janvier 2014. Néanmoins, on ne sait ce qui a provoqué ce changement de volume, genre une partie de corium qui a bougé dans l’enceinte.

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.
