Radiation level was picked up from 0.22~9.31 to 0.44~9.31 μSv/h around the depleted uranium after explosion. It was measured from 9:00 ~ 9:30 of 4/22/2012, when 7 hours had passed since first explosion.
9.31 μSv/h is extremely high. It shows it was severely radioactive even before explosion.
Depleted uranium was kept in 3379 of the 200 L drum cans, which are made of double stainless steel.
They were stocked in the warehouse located at 500m north west to the explosion point. From 1968 to 1973, they were used for catalyst containing uranium oxide in the process of manufacturing textile materials.
The blast broke the windows of the warehouse, but it is reported that the drum cans were not broken.
Iwakuni city government and Otake city government were not informed of the depleted uranium stocked in the chemical complex.

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.
