On the press conference of 2/7 AM, Tepco announced they ended up injecting 1094 Kg of boric acid to reactor 2 though they were planning to inject 960Kg.
At this moment, Nuclear Safety Commission stated they need to distribute potassium iodide tablet to the citizens in 30km area or even 50km area for possible nuclear accident. They say it is because they couldn’t give potassium iodide tablet to people in 311, but you can’t help questioning, why now ?
Mr. Koide talked on the radio show “Tanemaki journal” like below.
The actual problem is there is not even the way to know what’s going on inside of the container vessel.
Probably the fuel is as melted as mud. It’s attached to everywhere in the vessel, and the place that the mud is attached gets heated.
If they increase the water amount, the mud may move and the new place may get heated again.
so some place may get cool but other place may get extremely hot. so other places where no heat gauge is near may be over 100℃.
Even robot can’t get into the vessel. We can not see inside of the vessel for longer than several decades.
