From the article of Tokyo newspaper(1/8/2012 JST), it turned ou that the decreasing water level problem at reactor 4 was not stopped, it has been on-going at least until 1/7/2012.
It is assumed that the water in the cooling system is flowing into the container vessel instead.
Because nothing has been done to this trouble caused by the earthquake of 1/1/2012, the water will keep flowing into the container vessel. M4~5 level of the earthquake has started to happen frequently around Fukushima plants. We still need to keep our eyes on the reactors.
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.
