Breaking News: Possibility of hydrogen explosion

Over 1% of hydrogen was found in 2 parts of the pipe in reactor 1.

In order to take off the radioactive gas from container vessel,Tepco was planning to cut off the pipes connected to the container vessel.

In the process,near the pipes which they were planning to cut off on the first floor of the plant 1,they detected over 10,000ppm of hydrogen at 2 places.

Tepco announce that hydrogen explosion can happen only when 4% of hydrogen and 5% of oxygen are mixed together,so there is least explosion risk now.


However,they are injecting nitrogen to reduce hydrogen for now.

They have not checked if there is hydrogen left in reacor 2 and 3 yet.

“Expert”,Okamoto from Tokyo university suggests 3 possibilities.

1.The gas that caused the hydrogen explosion in March still remained there.

2.Water in the reactor produced hydrogen because of radiation.


They are still injecting nitrogen,but there may be hydrogen left in other places still.

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.
