Actual Fukushima worker talks: water purifying system has never worked

Following up this article 220 tons of highly radioactive water leaked and a part of it leaked to the sea

The water purifying system has never worked properly.

It was urgently constructed, the whole system can’t stand anymore.

These are the tweets of actual Fukushima worker Happy20790.

He explains how it is on the sight.

ただいまっ(^O^)今日は月曜日でお疲れ気味でし。汚染水処理システムも色々ガタが出てきました。昨日はたまたま建屋の外に汚染水が漏れたから報道あったけど…、最近いろんな場所でよく漏れてるんだ。

建屋って報道で言ってるけどコンクリートで基礎の土間を打って固めた場所に蛇腹ハウス建ててその中に装置があるんだ。装置稼働した初期も漏れたから途中からハウス内に堰を作ったんだ。堰の高さは20センチくらいかなぁ…。

オイラは最近蛇腹ハウスの中は線量高いから入ってないけど、前は水中ポンプで漏洩水を片付けたよ。だけどβ線量が高いからいつもより注意が必要なんだ。今回もβ線110mSv/hって報道してたけど、もっと高い場所もあるんだ。

蛇腹ハウスのコンクリート土間もまだ新しくて半年位しかたってないんだけど、突貫工事の短期間でコンクリート流して十分な乾燥期間もなくて装置設置してハウス組立たから割れが出たんだね。他の棟もひび割れてるかもしれないなぁ…。

各メーカーは通常の契約とは違って装置の運転やメンテナンス契約してないから装置設置して東電に納入したら完了で、あとは東電社員や直営企業で作業してるんだ。手に負えない時はメーカー使ってるけどね。ここにも予算の弊害があると思うんだけど…。

前にもつぶやいたけど、汚染水処理システムはまともな設計期間もなく応急処置で集めたり作ったものだから、早く恒久的な対策を取り入れて汚染水を完全に浄化するシステムを伴った海洋投棄システム作らなきゃダメだと思うんだ。

:側溝の事も前につぶやいたけど、早く今の側溝は流れて行かないようにつぶすか、下流に受けタンク設置して処理システムの一部に加えないとダメなんだ。雨が降ると地面の汚染も草木についた汚染も側溝から海に流れてしまうよ(;_;)

メーカーや作業員は減ってきてるけど、東電は行き当たりばったりの何か問題あったら対処する今のままじゃなくて、常に先手を打って欲しいんだけどね。今日は新たなプロジェクトの話したかったけど、またね。

Translation:

The contaminated water leaks a lot recently. This time, it went out of the “building” so it was reported but actually it happens frequently.

I called it “a building”, but it’s actually a temporary tent on a temporary concrete basement. It leaked from the first operation, so they made a tiny dam in it. Maybe it’s only 20cm high.

I don’t get into the tent recently because it’s too radioactive, but I used to pump up leaked contaminated water. The contaminated water emits a lot of beta ray, so you need to be careful.

This time, Tepco’s spokesman said it was 110 mSv/h, but it is higher at some points.

The concrete basement was constructed really urgently. They built the tent even before the concrete dried so it got cracked already. Other tent may have the same problems too.

Unlike our ordinary contract, makers only set the facility, they don’t take responsibility of handing or maintenance.

As I tweeted before, this water purifying system is not a long-lasting system. It is a temporary system without proper planning process. In order to release cooling water to the sea, we must install more proper facility.

Now the gutter is directly connected to the sea. They must be shut down or a dam must be made. Currently every time it rains, radiation on the ground and radiation stuck to the plants flow into the sea directly.

Makers and workers are already withdrawing from Fukushima plants, but Tepco has no long term plan. They need to predict the future risk and prevent it from happening in advance.

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.
