[Express] “Common usage pool may be more heated than SFP of reactor3”

Introducing important tweets as [Express] for simultaneous update.


[Express] "Common usage pool's temperature increasing rate is higher than SFP of reactor3 by 160%"
The temperature increasing rate while the coolant system is stopped for SFP of reactor3, 4 and common spent fuel pool.
SFP of reactor3 : 0.088 ℃/h (12/19/2012)
SFP of reactor4 : 0.25 ℃/h (10/24/2012)
Common spent fuel : 0.143 ℃/h (12/19/2012)

Common spent fuel pool has 6,375 assemblies of spent fuel, is located in only 50m west of reactor4. SFP of reactor3 has 514 assemblies of spent fuel and 52 assemblies of new fuel.

[Express] "Common usage pool's temperature increasing rate is higher than SFP of reactor3 by 160%"
La température monte alors que le système de refroidissement est arrêté dans les SFP (ndt: piscines à combustibles usagés) des  réacteurs 3 et 4 et dans la piscine de dégagement commune (ndt : qui reçoit des barres de tous les réacteurs).
SFP3 : 0,088 ℃/h (19 dec. 2012)
SFP4 : 0,25 ℃/h (24 oct. 2012)
Piscine commune: 0,143 ℃/h (19 dec. 2012)

La piscine de dégagement commune contient 6 375 assemblages de combustible usés, elle est à seulement 50 m à l’ouest du réacteur 4. La SFP3 contient 514 assemblages usés et 52 neufs.

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.
