Last M5.8 did cause plant abnormality / Coolant water volume to reactor2 “spontaneously” increased

On 9/20/2013 (JST), M5.8 of the earthquake hit Fukushima plant area.

Tepco was reporting the plant parameters showed no abnormality, but on 10/4/2013, they announced it was observed that the water volume to inject into reactor2 was increased from 1.8 to 2.0 m3/h after the earthquake.

According to Tepco, it wasn’t operated manually. Also, the water volume is not designed to be in sync with the temperature or the pressure inside of the reactor. Tepco stated probably it had something to do with the earthquake.

Le dernier séisme M5,8 a perturbé la centrale : le volume des eaux de refroidissement du réacteur 2 a “spontanément” augmenté


Le 20 septembre 2013 (JST), un séisme de magnitude 5,8 avait frappé la région de la centrale de Fukushima.

Tepco avait rapporté que les paramètres de la centrale ne présentaient aucune anomalie mais le 4 octobre 2013 ils déclarent qu’ils ont observé que le volume d’eau à injecter dans le réacteur 2 était passé de 1,8 à 2,0 m³/h après le séisme.
Selon Tepco, ça n’a pas été changé manuellement. En outre, le volume d’eau n’est pas conçu pour rester synchrone avec la température ou la pression dans le réacteur. Tepco affirme que c’est sans doute lié au séisme.

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.
