Reactor2 temperature jumped up by 120℃ within 12 hours

The temperature of reactor2 is almost reaching 265℃.

The thermometer attached on the upper part of RPV2 recorded the rapid increase of temperature from 143.4℃ to 262.3℃, when was from 23:00 of 2/15/2013 to 11:00 of 2/16/2013.

On 2/10/2013, Fukushima Diary reported the temperature of bottom part of RPV was reaching 250℃. Now it is 284.4℃.

According to Tepco, both of the thermometers are supposed to be disordered.

La température du réacteur 2 est montée de 120 °C en 12 heures

 

La température du réacteur 2 atteint presque les 265 ℃.

Le thermomètre fixé dans la partie supérieure de la RPV2 (enceinte principale de confinement du réacteur 2) a enregistré une montée rapide de la température de 143,4 °C à 262,3 °C, à partir de ce 15 février 2013 à 23:00 et jusqu’à 11:00 le lendemain.

Le 10 février 2013, le Fukushima Diary rapportait que la température de la partie basse de la RPV atteignait les 250 ℃. A présent elle est à 284,4 °C.

Selon Tepco, les deux thermomètres sont soi-disant en panne.

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.
