【速報】(東電からのメール)1)○昨日(1月31日)午後10時30分頃、福島第一原子力発電所4号機原子炉建屋1階にあるジェットポンプ計装ラック内の計器テストラインより漏えいしていることを当社社員が発見。(続 Source

【速報】2)○その後、午後10時43分、計装ラックに繋がる元弁を閉めることにより、水の漏えいは停止。○床面は瓦礫が散乱した状態であり、漏れた水の量は確認できた範囲で約6リットル。なお、原子炉建屋外への流出はない。(続 Source

【速報】3)○テストライン内の水を採取し、放射能濃度を測定した結果、漏れた水は原子炉ウェル水と推定。(分析結果:35.5 Bq/cm3)(参考:昨年12月8日に原子炉ウェル水を分析した結果、39 Bq/cm3)(続 Source

【速報】4)○本件について、福島においては本日(2月1日)午前の定例レクで、本店においては午前11時に説明。(以上、東京電力からのメール)(35.5Bq/cm3は35500Bq/Lなので、けっこう濃度高いと思います)Source

<Translation>
1/31/2012, 10:30PM, Tepco employee found water leakage from the test line of jet pump calculation rack located on the first floor of reactor 4.
10:43 PM, they stopped it by turning off the tap connected to the rack. The floor is full of the debris. As long as they confirmed, more than 6L of water leaked. None of it leaked to the outside of the reactor building.
From the result of the measurement, it was contaminated as 35.5 Bq/cm3 (= 35,500 Bq/L), they assume the water is from the well of the reactor. (Cf. The measurement data of the well of reactor was 39 Bq/cm3 on 12/8/2012.)
They are going to explain it on the press conference of 2/1/2012 11:00AM.

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.
