Reactor1 losing water and temperature is in increasing trend

RPV water level is decreasing in reactor1, and PCV temperature is in the reverse trend to be picking up.

Every time RPV water level drops, PCV temperature picks up.

Reactor1 losing water and temperature is in increasing trend

 

The original version of the graph above is from a Japanese forum, 2ch but it was confirmed to be correct from Tepco’s parameters. [Link]

 

圧力制御プールの水位が 1号機で 下がっていますし 水温は 反対に 上昇傾向にあります。

毎回 水位が下がると 水温が上がっているようです。

この上のグラフの元は 日本語のフォーラム、2チャンネルからですが 東電の表からも 正しいことが 確認されました。[Link]

Le réacteur 1 perd de l’eau et sa température augmente

Le niveau d’eau du RPV (enceinte primaire) du réacteur 1 décroit et la température de celle de confinement (PCV) suit la tendance inverse, en montant.
Chaque fois que le niveau descend dans la RPV, la température de la PCV monte en flèche.

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.
