Breaking News: Fukushima in recriticality

At four different places in Japan,Iodine 131 was detected between 15th-25th August.

The half life time of Iodine 131 is about 8 days.

It’s natural to think Fukushima got into the recriticality state.

1) Between 8/15~16,they detected 150 Bq/kg of Iodine 131 from sewage sludge in Tokyo.

2) Between 8/25~9/6,they also detected 2,300 ~ 4,800 Bq/kg of Iodine 131.

Sludge sampled on August 25th from Maesawa sewage clarification center in Oshu city, marked 2,300 becquerel in iodine131. What the heck is this…

Klärschlammproben vom 25. August aus der Maesawa Kläranlage in der Stadt Oshu weisen 2,300 Becquerel Iod 131 auf. . Was zum Teufel ist das…

3) and today,they announced they detected Iodine 131 in Niigata and Nagano.

Having Iodine 131 detected in four different places nearly at once,it’s very likely that Fukushima nuc plant has got into recriticality state again.

For now,no public announcement was made as always.They will announce it when it’s too late.

Now it is not sure that in which reactor the recriticality is starting,but from a source,it might be in the spent fuel pool in the third reactor or the forth reactor ,however it’s still an unconfirmed information.

It has been 6 months,but nothing has been improved. Still even a temperature indicator is not properly set at each reactor.It’s almost 100% sure that fuel rods have melted out and started sinking into the ground in some of the reactors.

It’s rational that recriticality will keep happening continuously for decades ,until all of fuel rods are taken out and kept safe.

The future of this blog is bright.

About this site

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.
