Tepco punched an access hole to PCV of reactor1

On 9/26/2012, Fukushima diary reported the rapidly increasing temperature in PCV1. (cf. PCV temperature is rapidly increasing in reactor1, “10℃ in 2 days”)

On 9/27/2012, Tepco reported they punched an access hole to PCV of reactor1.

It is not clear if it affected the increasing temperature, but it’s not starting to decrease yet.

Tepco fait un trou dans l’enceinte du réacteur 1 (PVC1) pour y accéder

Le 26 septembre 2012, Le Fukushima Diary a rapporté l’augmentation rapide de la température dans la PCV1. (cf. La température de l’enceinte primaire du réacteur 1 augmente rapidement, 10℃ en 2 jours)

le 27 septembre 2012, Tepco a rapporté qu’ils perçaient un trou d’accès dans la PCV1 (= Enceinte de confinement primaire du réacteur 1).

On ne sait pas si ça influe sur l’augmentation de température mais elle n’a toujours pas commencé à décroître.

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.
