Water level is still decreasing at reactor 4

Following up this article http://fukushima-diary.com/2012/01/emergency-mail-from-tepco-to-mass-media-about-reactor-4/

From the article of Tokyo newspaper(1/8/2012 JST), it turned ou that the decreasing water level problem at reactor 4 was not stopped, it has been on-going at least until 1/7/2012.
It is assumed that the water in the cooling system is flowing into the container vessel instead.
Because nothing has been done to this trouble caused by the earthquake of 1/1/2012, the water will keep flowing into the container vessel. M4~5 level of the earthquake has started to happen frequently around Fukushima plants. We still need to keep our eyes on the reactors.

4号機タンクの水位低下

2012年1月8日
一月一~七日の一週間、福島第一原発では、一日午後に4号機の使用済み核燃料プールに隣接したタンクの水位が急に下がった。直前に東北や関東で震度4を記録した地震の影響とみられる。
タンクの水は蒸発で減るが、この時は通常時の約五倍のペースで低下。当初、東京電力は水漏れを疑った。その後の調査で、水漏れはなく、地震の影響により、プールからタンクに流れ込む水が一時的に止まっていただけの可能性が高いと分かった。
一方、高濃度汚染水を処理した水が流れるホースに雑草のチガヤが刺さり、小さな穴から水漏れを起こす現象に現場は悩まされてきた。東電が集計したところ、昨年七月以降、二十二件もあった。
原子炉への循環式注水は長期にわたって続ける必要があり、こうした小さな問題は早いうちに解決しておくことが重要。東電は対応策を練っている。

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.
