Another leakage at reactor 4. 100 microSv/h on surface 2

 

Tepco failed in pipe pressure resistant test to have contaminated water leak.
1/20/2012, Tepco tested the pressure resistant by using low level of contaminated water before transferring high level of contaminated water from the basement floor of turbin building of reactor 2. They found it leaking from a joint on the first floor of the turbin building for reactor4 for some reason.
Tepco measured 100 microSv/h from the surface of leaked water.

漏れた汚染水は低濃度=配管の耐圧テストで使用―東電
時事通信 1月21日(土)19時25分配信
東京電力福島第1原発4号機のタービン建屋1階で水漏れが見つかった問題で、同社は21日午後、漏れたのは低濃度汚染水で表面線量は毎時0.1ミリシーベルトだったと発表した。
東電は20日、2号機タービン建屋地下から高濃度汚染水を集中廃棄物処理施設内の建屋へ移送する前に、低濃度汚染水を使って配管の耐圧テストを実施。漏れたのはその際、配管に残った低濃度汚染水とみられ、漏えい場所は配管のつなぎ目だったという。

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.
