Breaking News: M7 hits Japan and water leakage at reactor4

14:34 1/1/2012 JST, magnitude 7 hit Japan. Epicenter is 31.416°N, 138.155°E

It was scale 3 ~ 4 in Tokyo ,and also Fukushima but the scale of Fukushima nakadori, where Fukushima plant is, is not announced on the page of Japan Meteorological Agency.

Though the connection with this earthquake is not clear, Tepco announced water is leaking from the cooling system of spent fuel pool in reactor 4.

The water level of the tank to pool overflowed water from spent fuel pool decreased by 8cm from 2PM to 5PM on 1/1/2012.

This tank is to give back the water to the spent fuel pool after purifying the water. Tepco assumes the leakage is at a joint of pipe but it’s not detected yet.

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.
