Coolant system of SFP in reactor2 is stopped

Since 14:01 of 6/27/2012, the coolant system of SFP2 has been stopped.
They confirmed the cooling pump of systemA automatically stopped by the web camera of the seismic isolation building at 14:22. They caused the short circuit to set a digital recorder of a flow meter.

The water temperature was 22.9℃, it is estimated to increase at 0.24℃/h by Tepco.
Tepco states they confirmed no water leakage at 14:40, and the water temperature is under control.

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.
