Boring survey around reactor 2 is coming to the climax. As a result, the announcement of the government and Tepco has to be denied. If it’s soft material, they can do horizontal boring with such a weak equipment (like the top picture ) but when it comes to the concrete of the reactor building it’s impossible. They need to do boring with a foreign heavy equipment at an angle. They do boring to reach to under the container vessel. (like the bottom 2 pictures)
When they do boring where they don’t need to take a sample they drill roughly with this green rotary diamond bit but the dust is lethal because it’s too radioactive. When they need to take a sample, they change the diamond bit to hole saw type of bit. However, diamond is weak for the heat so when it’s hotter than 500℃ they use the standard type of the tungsten carbide instead. The bottom 3 pictures are the samples taken.
Taking a part of the concrete slag sample. Put it into the lead case (Chiyoda technol) and take it to a lab.
I don’t know if it’s because they gave sea water to cool down or because it’s brackish area, if natrium (sodium salt) of sea water made a chemical reaction with calcium carbonate in the concrete to become diuranate natrium (sodium diuranate) or not, it looks yellow as yellow cake.
Probably the iron part of the core is uranium pellet unreacted – not sure yet because it’s still before the analysis.
It’s beyond the max reading of 500X100 CPM. These yellow concrete slags come out from under the building one after one. It means that the container vessel is melting like honeycomb at least – doesn’t it? Otherwise why would metal uranium comes out of there ?
made up my mind to take out the slags from the shelter to take pictures of them.
wore protective clothing. When it’s taken out, it was over 400 ℃ but now it’s cooled down to 100 ℃.
Can you see this big metal crystal (extremely radioactive) and the oxidized concrete looking like yellow cake? Can you believe it is out of the container vessel. It’s over 500 mSv/h, my geiger counter went over the limit.
was scared so put it back to the shelter soon as I took a couple of the pictures.
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.
