Spent fuel in JP amounts 26,000 vitrification, “50yrs cooling before 100,000yrs geographical disposal,1500Sv/h surface”

The Science Council of Japan suggested JAEC (Atomic Energy Commission of Japan) to review geographical disposal of radioactive vitrified object.

Vitrified object is produced by reprocessing spent nuclear fuel. The surface dose is 1500Sv/h, which reaches fatal dose in 20 seconds beside the object.
The total spent fuel amounts 26,000 vitrified objects in Japan. They need 30 ~ 50 years to cool before they are stocked 300m deep underground for more 100,000 years.
Japan is a volcanic country. It is impossible to find a proper ground to keep them for 100,000 years.

Le combustible usagé du Japon représente 26 000 vitrifications, 50 ans de refroidissement avant 100 000 ans de décharge en profondeur, objets à 1 500 Sv/h

Le Science Council of Japan a proposé à la JAEC (Atomic Energy Commission of Japan) de revoir les lieux de décharge des objets vitrifiés radioactifs.

Les objets vitrifiés sont produits en retraitant les combustibles nucléaires usagés. Leur rayonnement de surface est de 1 500 Sv/h, c’est à dire la dose mortelle en 20 seconds à côté de l’objet.
La quantité totale de combustibles usagés vitrifiés du Japon est de 26 000. Ils nécessitent de 30 à 50 ans de refroidissement avant d’être entreposés à 300 m de profondeur dans le sol et pour plus de 100 000 ans.
Le Japon est un pays volcanique. Il est impossible d’y trouver un emplacement pouvant les garder y maintenir pendant 100 000 ans.

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.
