Extremely radioactive debris found on the top of reactor3 North side, Tepco “Safely moved to the South side”

On 5/4/2013, Tepco released the press release to announce they found the extremely radioactive debris on the top of reactor3.

At this moment, English version of the report is not published yet.

The debris was found in the North side of the top, where used to be the operation floor.

When they loaded it onto the remote controlling truck, they measured 540 mSv/h. However it is not announced how far they measured it from the surface of debris.

At 13:45, they regulated entering around the truck, but they moved the debris to the temporary storage facility of highly radioactive debris on the south side of the reactor building.

Tepco announced they are going to move it to the solid radioactive waste storage facility on the North side of the seismic isolation building within 5 days.

Des gravas extrêmement radioactifs côté Nord au sommet du réacteur 3. Tepco : “déplacés côté Sud en toute sécurité”


Le 4 mai 2013, Tepco publie un communiqué de presse pour annoncer qu’ils on trouvé des gravas extrêmement radioactifs au sommet du réacteur 3.

Pour l’instant, la version anglaise du communiqué n’est pas encore publiée.

Ces gravas ont été trouvés au sommet, côté Nord, à l’étage utilisé pour les opérations.
Lorsqu’ils l’ont chargé sur le camion télécommandé, ils ont relevé 540 mSv/h. Ils ne disent toutefois pas à quelle distance ils ont fait la mesure.
A 13:45, ils ont contrôlé les entrées autour du camion. Ils ont déplacé ces gravas dans l’entrepôt temporaire de stockage des gravas extrêmement radioactifs qui est situé au Sud du bâtiment du réacteur.
Tepco annonce qu’ils vont le déplacer d’ici 5 jours vers l’entrepôt de stockage des déchets radioactifs solides situé au nord du bâtiment d’isolation sismique.

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.
