Breaking News: Hydrogen keeps coming up


Tepco tried to reduce hydrogen in the pipes of reactor 1 but they failed.

When there is more than 1% hydrogen, it may cause hydrogen explosion.

Apart from other flammable kinds of the gas, hydrogen is assumed be at 63% in the pipes.

At first they managed to reduce it to be under 0.1%,but 1~2 hours later, it increased to 3.9% again.

There is an explosion risk in this process.

Actual worker of Fukushima tweeted like below.

Today we reduced the hydrogen in the pipes but it came up again.. Tomorrow we are planning to cut off the pipe but hydrogen needs to be less than 1%.

Tepco says extra hydrogen comes up from other pipes but I suspect it comes from underground..

We don’t have proper equipment..I wonder if they can really cut off the pipe. I’ll take a day off tomorrow but I’m worried.


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.
