6/14/2012, Tepco announced 3 tones of contaminated water leaked from the decontamination system of Areva. It contains 4.4E+8 Bq/m3 of cesium.
1.32E+9 Bq/m3 of cesium was leaked in total. The leaked amount of Strontium or Tritium is not announced.This system was stopped but it has been under circulation operation from 5/21/2012.

The leaking point is not identified yet. Tepco states it didn’t leak out of the system of Areva.

At 7:00 6/14/2012, decontamination system alerted to stop the operation. Nuclear worker confirmed 3 tones of contaminated water was leaking on the 1st floor of the building.

 
東京電力は14日、福島第一原子力発電所の高濃度汚染水の除染装置(仏アレバ社製)から汚染水3トンが漏れた、と発表した。

漏えいか所の特定を進めているが、外部への流出はないという。

東電によると、同日午前7時頃に除染装置の異常警報が鳴って、運転を停止。作業員が確認したところ、装置のある建屋1階の床に濃度の低い汚染水3トンがたまっていた。1立方センチ・メートルあたり440ベクレルの放射性セシウムが検出された。

除染装置は運用を停止していたが、5月21日から装置配管内の放射性物質を取り除くために循環運転を行っていた。

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.
