Reactor1 reaching 49℃, increased by 3℃ within 24 hours

On 5/14/2013, Fukushima Diary reported ”3 thermometers indicating the rapid increase of temperature in reactor1 [URL]”

One of the thermometers indicated the temperature of PCV reached 49℃ at 11:00 of 5/15/2013.

It increased by 3℃ since 11:00 of 5/14/2013.

The increase of temperature indicated by these three thermometers is accelerating. There is no official explanation of Tepco.

Le réacteur 1 atteint les 49°C, une montée de 3° en 24 heures


Le 14 mai 2013, le Fukushima Diary publiait 3 thermomètres indiquent une hausse brutale de la température dans le réacteur 1

Le 15 mai 2013 à 11:00, un des thermomètres indique que la température de la PCV (enceinte primaire) a atteint 49°C.
C’est monté de 3°C depuis le 14 mai à 11:00.
L’augmentation de température indiquée par ces trois thermomètres accélère. Il n’y a aucune explication officielle de Tepco.

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.
