Tepco and Nuclear and Industrial Safety Agency are going to take out 2 of the 204 new fuel assemblies soon in order to check the damage on cladding tube caused by sea water injected just after 311, but they are not going to announce the date. The reason is supposed to be the protection of nuclear material.
Tepco is planning to start taking out all the nuclear assemblies by the end of 2013.
The fuel assemblies will be taken out by the crane, put into the cast on the top of the reactor building. Large crane will take them down to the ground to shared pool to check the surface of fuels in detail.
The radiation level of new fuel assemblies is usually about 25μSv/h, but if the radiation level exceeds 30mSv/h on surface of the pool, they are to stop taking out the fuel assemblies.
If I was in Tokyo with my child, I would stay away from Tokyo just in case.
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.
