Tepco temporarily stopped updating the plant parameters of reactor2 including the temperature data

In reactor2, two thermometers are still indicating the increasing temperature in RPV even after Tepco declared they were broken. [Link1]

In the afternoon of 1/16/2013 (JST), Tepco stopped updating the plant parameter (*1) of reactor2, which includes the issued temperature data. (1/15/2013 17:00 ~ 1/16/2013 11:00) The reason is not announced.

About 6 hours behind their schedule, they published the data but those two thermometers recorded the huge increase of temperature, 112.8 → 120.3 and 96.3 → 104.4 .

Due to the lack of contaminated water storage, Tepco can no longer increase the volume of water to increase even if those thermometers are valid to show the increasing temperature. (cf, Tepco plans to discharge contaminated water into the environment, “Getting permission of related departments” [Link2])

Tepco stopped updating the plant parameters of reactor2 for nearly 20 hours

Tepco a temporairement arrêté de mettre à jour les paramètres usine du réacteur 2, dont les températures

Dans le réacteur 2, deux thermomètres indiquent toujours que la température augmente dans la RPV même après que Tepco les ait déclarés cassés. [Lien1]

Dans l’après-mid du 16 janvier 2013 (JST), Tepco a arrêté de mettre à jour les paramètres usine (*1) du réacteur 2, ce qui inclue les données de température. (15 janvier 2013 17:00 ~ 16 janvier 2013 11:00) La raison n’en est pas donnée.

Environ 6 heures avant, ils avaient publié les données mais celles des deux thermomètres enregistraient une grosse montée de température, 112,8 → 120,3 et 96,3 → 104,4 .

A cause de la pénurie en espace de stockage des eaux, Tepco ne peut plus augmenter le volume de l’eau même si ce qu’indiquent ces thermomètres sont valides. (cf. Tepco se prépare à jeter les eaux contaminées dans l’environnement, “Avec la permission des services concernés” [Lien2])

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.
