Tepco to stop coolant system of SFP in reactor3 from 12/12 to 12/18 in the risk of aftershock after M7.4

At 14:02 of 12/12/2012, Tepco stopped the coolant system of SFP in reactor3 to add valves and check clack valves. It will be stopped until 12/18 while Meteorological agency is warning about the possibility of M8.0 after the M7.4 on 12/7/2012.

Tepco states the water temperature increases at 0.16℃/h without coolant system. It would be increased up to 24℃, but still it’s cooler than the safety limit of 65℃.

Tepco coupe le système de refroidissement de la SFP3 du 12 au 18 décembre en plein risque de réplique du M7.4

Le 12 décembre 2012 à 14:02 , Tepco a stoppé le système de refroidissement de la  SFP (piscine des combustibles) du réacteur 3 pour changer des valves et contrôler des clapets. Il est arrêté jusqu’au 18 décembre alors que l’agence météo émet un avis d’alerte sur la possibilité d’un séisme M8.0 après le M7,4 du 7 décembre 2012.

Tepco affirme que la température de l’eau monte de 0,16 ℃/h sans système de refroidissement. Elle devrait monter jusqu’à 24 ℃ ce qui reste toujours loin de la limite des 65℃ de sécurité.


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.
