Actual Fukushima worker suspects an explosion caused 8.5t of water leakage

 

 

Following up this article ..301,750,000 Bq leaked from reactor 4

A Fukushima worker Happy20790 commented 8.5tones of water would take too long to leak from the pipe (Internal diameter 6mm).

続き4:ジェットポンプの計装ラインは炉内のジェットポンプを構成してるディフューザっていう配管に付いててセンシングラインっていうチュービング配管でジェットポンプ内の流量を計測してるラインなんだ。炉内で付いてる位置は燃料域でいうと下の方なんだよね。Source

The gauge of jet pomp, where the 8.5 tones of water is supposed to have leaked is attached to diffuser. It’s at the low part of the reactor.

続き5:…という事は炉水現在の高さからしてかなりの水頭圧がかかるはずでかなりの勢いで漏れたはずだけどその形跡は見当たらない。ドライウェル内のバルブリーク量が少しならポタポタもわかるんだけど、それだったら8.5t漏れるのに相当日数がかかると思うんだ。Source

That means the water must have “splashed” with strong hydraulic head pressure but there is no evidence to prove such a “splash” have happened. Another possibility is that water leaked slowly from the valve in dry well, but it must have taken days to leak no less than 8.5 tones of water.

続き6:それと配管が外れた原因もわからない。写真見たけど配管は切れたんじゃなくて抜けてるんだよね、ナットも緩んでないし。あそこは袋ナットで締め付けるタイプでセージロックタイプなんだけど、抜けるにはかなりの衝撃応力を加えないと外れないよ。地震か爆発かなぁ…?Source

and I can’t understand why the plug was taken off. I saw the picture but the pipe wasn’t cut. It’s gotten the plug taken off. The nut wasn’t loose. It must have needed a lot of impact stress to take off the plug because it uses hexagon cap nut. I wonder if it was because earthquake or explosion..

続き7:凍結で外れたっていう理由も考えられない、何故ならヤードにも同じようなのあるけど今までオイラはそんな事象を見たことも聞いたこともないんだよね。それに、他にも沢山あるのにあの一カ所だけ外れてるし…。Source

It can’t be congelation because I haven’t seen such an accident outside. and there are a lot similar to this but all the rests are safe.

続き8:だからオイラはあそこから漏れたのは6リットルだけでドライウェル内のバルブからあのバルブ間の溜まり水が漏れたんじゃないのかなって勝手に推測してるんだ。内径6mmの配管から8.5t漏れるのにはどの位の時間がかかるんだろ?あとで計算しなきゃでし。ん~誰か計算して欲しいでし。Source

I suspect the 8.5tones of leaked water is from a different part of the 6L of leakage. I guess it’s from the valve in dry well. They announced the water is from the jetpomp pipe but the internal diameter is only 6mm. It takes too long to leak 8.5 tones of water.

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.
