Thermometer of Reactor 2 indicates rapid increase in temperature again / 79℃ on 5/10/2015

Following up this article.. A thermometer of Reactor 2 indicates a rapid increase of temperature / From 20℃ to 70℃ within 6 hours [URL]


Tepco’s plant parameter is showing that one of the thermometers is indicating a rapid increase in Reactor 2 temperature again.

The parameter is updated every 6 hours. This thermometer is installed in PCV (Primary Containment Vessel) of Reactor 2, and it is not considered to be out of order.

The temperature started rising in the end of April. It was below 55℃, however it got in the constant increasing trend. At the moment of 23:00 on 5/10/2015 (JST), the temperature is already 79℃.

Tepco has made no announcement on this abnormality in reactor temperature.

Les paramètres de la centrale de Tepco montrent qu’un des thermomètres indique à nouveau une montée rapide de la température dans le réacteur 2.

Ce paramètre est mis à jour toutes les 6 heures. Ce thermomètre est installé dans la PCV (Primary Containment Vessel = Enceinte de Confinement Primaire) du réacteur 2 et il n’est pas considéré comme déficient.
La température a commencé à monter fin avril. Elle était en-dessous de 55 ℃ mais est restée sur la tendance ascendante. Au 10 ma 2015 23:00 (JST), la température est déjà à 79 ℃.
Tepco n’a fait aucune déclaration sur cette anomalie de la température du réacteur.

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.
