News: Nuclear and Industrial Safety Agency calculated China syndrome
Nuclear and Industrial Safety Agency conducted a trial calculation of China Syndrome on 3/25.
Though they kept stating “Just a part of nuclear fuel rods are damaged” at press conference, Japan Nuclear Energy Safety Organization was ordered to estimate the scale of china syndrome by Nuclear and Industrial Safety Agency and they released the data today.
They assumed that all the nuclear fuel rods melt and penetrate the bottom of the container vessels.
According to their estimation, in case the water supply is stopped, melted nuclear rods keep penetrating the pedestal, which is the 3 m thickness of the floor made of concrete under the container vessels, for 10 days at reactor 2 and 3.
At reactor 1, penetration keeps continuing for 8 days and stop at 1.8m deep.
They also calculated the case of when all the fuel rods drop down at once, and also the case of when melted fuel splashed as jet.
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.
