(New disclosure: Fukushima nuclear power plant)
Jiji Press has reported that the following reports are performed and there is a possibility that contaminated water will begin to leak from a No. 1 building.
The problem has come out in the next from No. 1 No. 2 or 3 and the next, and if it goes as it is, a Fukushima Daiichi nuclear power plant may develop into the situation which is abandoned completely.
A No. 1 building is also pointed out in a pollution source or the radioactivity groundwater regulation committee task force in = Fukushima 1st.
In the problem out of which the groundwater polluted with the 1st nuclear power plant of Tokyo Electric Power Fukushima by the radioactive material is flowing into the sea, the task force of the Nuclear Regulatory Commission which argues about the measure against contaminated water was held on the 24th, the high-level radioactive water with which No. 1 turbine building underground was covered leaked, and the opinion which points out a possibility of soiling groundwater succeeded one another.
Toden explains that the high-level radioactive water which flowed into the trench (underground pipelines, such as a cable) of No. 2 or 3 just behind the accident might ooze out in soil, and may have soiled groundwater until now.
In order to prevent an outflow to the sea, neighboring groundwater was pumped up, and the soil near the shore protection is hardened, but the disclosure from a building etc. is not accepted.
A new measure is needed if contaminated water has leaked from the No. 1 building.
According to the data submitted to the task force, the concentration of radioactive material tritium was so low in the well for observation which was about 45 meters away from shore protection by the No. 1 turbine building sea side the middle of November, last year that it is undetectable, but he is the Noboru Gokami.
With the groundwater extracted on the 19th of this month, the peak price of this well was updated at 5600 Bq per liter.

(新たな漏えい:福島原発)
時事通信は、以下のような報道を行っており、一号機建屋から汚染水が漏れ出している可能性があると報じています。
1号機2,3号機、次から次へと問題が出てきており、このままいけば、完全に福島第一原発は放棄するような事態に発展するかも知れません。
1号機建屋も汚染源か=福島第1の放射能地下水―規制委作業部会で指摘
東京電力福島第1原発で放射性物質に汚染された地下水が海に流出している問題で、汚染水対策を議論する原子力規制委員会の作業部会が24日開かれ、1号機タービン建屋地下にたまった高濃度汚染水が漏れ、地下水を汚している可能性を指摘する意見が相次いだ。
東電はこれまで、事故直後に2、3号機のトレンチ(ケーブルなどの地下管路)に流れ込んだ高濃度汚染水が土壌にしみ出して地下水を汚した可能性があると説明。海への流出を防ぐため付近の地下水をくみ上げ、護岸近くの土壌を固めているが、建屋などからの漏えいは認めていない。
1号機建屋から汚染水が漏れていれば、新たな対策が必要となる。
作業部会に提出された資料によると、1号機タービン建屋海側で護岸から約45メートル離れた観測用井戸では、放射性物質トリチウムの濃度が昨年11月中旬は検出不能なほど低かったが、その後上昇。今月19日に採取した地下水では1リットル当たり5600ベクレルで、この井戸の最高値を更新した。
