Actual Fukushima worker concerns reactor can’t last so long

 

Following up this article ..Video of endoscope operation to reactor 2

Actual Fukushima worker Happy20790 concerns reactor can not last until they manage to take out the fuel debris. He tweeted about it on 1/20/2012.

ただいまっ(^O^)今日は昨日と違ってさぶかったでし(;_;)昨日の2号機の写真じゃよくわかんない部分が映像だとよくわかるでし。SUS配管の腐食はみられなかったけどカーボン配管の腐食はかなり進んでる。燃料デブリ取出し開始の10年後までは絶対にもたないと思う。Source

<Translation>

From the video of endoscope, SUS pipes were not so corroded but carbon pipes have gone so corroded. We are supposed to start taking out the fuel debris in 10 years from now but I bet it does not last so long.

続き1:PCV壁面の塗装もシステム7以上の仕様だけど塗装が浮き上がって壁面の腐食も進んでる。かなりの高温だったんだね。機器ハッチやエアロックはもっと薄いから心配なんだけど…。きっとゴムパッキンもダメだろうなぁ…。Source

The coating of the PCV wall is also being ripped off and the wall itself is very corroded though it’s better spec than system7. It must have been such a heat. Hatch of the operation control or airlock are even thinner so I’m worried about that too. I suppose rubber packing is also damaged..

続き2:あと上部からの落ちてくる水なんだけど、ドライウェル内の温度から考えて結露水にしては量が多すぎる感じがする。配管の破断もかんがえられるけど可能性は低いと思う。Source

The dripping water is too much for the temperature of dry well. feel like it’s not the evaporated water. It could be the pipes cut off, but it’s least likely.

続き3:オイラはどこか上部のフランジ部分が開いてるか、バルブのグランド部分やボンネットからの漏洩の可能性が高いと思うんだ。2号機は他の号機より謎が多く感じる。オイラは2号機の配管爆発も謎なんだよなぁ…。Source

<Translation>

I think some flange parts are opened in the upper part of reactor or grand parts of valve or bonnet are leaking water. There are a lot of the things I can’t figure out about reactor 2. For me, the explosion of the pipes of reactor 2 is a mystery too..

Tepco started endoscope operation from reactor 2 because it is the least damaged, but the worker tells even reactor 2 will not last until they take out fuel debris in 10 years from now. Also, he thinks the water dripping from the above is too much for evaporated water, there must be some open part because of damaged valve or bonnet.
