Breaking News: Hydrogen keeps coming up

10/8/2011

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.

ただいまっ(^O^)今日は昨日よりもマイカーいたよ。1号機の配管内の水素置換したけど…、また上がってきちゃって…。明日、配管切る予定なんだけど水素濃度が1%未満にならないと切らないのだ。

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%.

続き:東電は当該配管部だけの溜まりって言ってたけど、やっぱり地下のトーラス内から廻ってくるんじゃないかなぁ…?水系の隔離弁じゃ止まらないよなぁ…。明日切れるかなぁ?因みにオイラは明日休みなんだけど心配でし。

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.
