NISA investigated chemical complex in Iwakuni

Following up this article..Chemical complex had second explosion and radiation measurement is nearly impossible

After fire was finally extinguished at 14:30 of 4/23, when 36 hours had passed from the first explosion, Nuclear and Industrial Safety Agency investigated the plant in AM of 4/24 with police and fire department. 

The state of radioactive contamination is still not known.  The depleted uranium was stocked at 400m away from the exploded point but glasses of the windows were broken at 6km north to the plant and the explosion caused an earthquake of scale 1 in Iwakuni city, Waki cho and Otake city.

On 4/24, 6 tones and 6m’s long debris was found at the outlet of Oze river between Yamaguchi and Hiroshima prefecture, where is 700m away from the plant.

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.
