Contaminated water leaked like blowing mist

Contaminated water leaked like blowing mist

 

Tepco was improving soil. The trouble happened near the pump room to push filtered water for soil improvement operation.

12:45 5/9/2012 Monitoring camera caught contaminated water was leaking like blowing mist.
13:00 Stopped the pump to confirm the water leakage was stopped by monitoring camera.(13:03)
13:07 Turned off the bulb of filtered water to find a crack on the hose connected to the pump.
No leakage to outside of the plant area. The surface dose of the leaked water was 300 ~ 400 μSv/h.

Note : You can see the trail of shoe under the leaking hose.

前回からの主な変更点は以下のとおり。

1.原子力発電所関係
・2号機タービン建屋地下の滞留水を雑固体廃棄物減容処理建屋へ移送(5月3日14:52から5月9日10:30)
・地盤改良工事用のろ過水を送るポンプ室付近から水が霧状に吹き出していることを監視用カメラにより確認(5月9日12:45頃)。ポンプを停止(同日13:00)し、水の漏えいが停止していることを監視用カメラにより確認(同日13:03頃)。ろ過水の供給元弁を閉止(同日13:07)。その後、現場確認により、ポンプに接続しているホース(ろ過水用)にき裂が発生していたことを確認。
漏えいした水はろ過水であり、敷地外への漏えいはない。今後、ホースの交換を行う予定。(なお、水の表面線量率は300から400μSv/h程度

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.
