4 fuel assemblies found deformed after removing the debris in SFP of Reactor 3

Following up this article.. Tepco released the video and photos to remove debris from SFP 3 [URL]

 

On 8/4/2015, Tepco announced they found 4 fuel assemblies deformed in SFP 3 (Spent Fuel Pool Reactor 3).

These assemblies were under the removed 20 t of the debris. Tepco investigated it by underwater camera.

The deformed parts are called handle on the top of the assembly. It will be more difficult to remove the fuel assemblies.

It has not been announced how Tepco is going to remove the stored fuel assemblies from SFP 3 yet.

In those released photos, the pool looks blue for some reason.

4 assemblages de combustible trouvés déformés après le retrait de 20 T de gravas de la SFP 3

Le 4 août 2015, Tepco annonce qu’ils ont trouvé 4 assemblages de combustible déformés dans la SFP 3 (Spent Fuel Pool Reactor 3 = piscine à combustibles usagés du réacteur 3).

Ces assemblages étaient sous les 20 t de gravas retirés. Tepco les a examinés avec une caméra amphibie.
Les parties déformées sont les poignées de saisie du haut des assemblages. Il sera plus difficile de retirer ces assemblages.
Il n’est pas encore précisé comment Tepco va retirer les assemblages de combustible de la SFP 3.
Dans ces photos publiées, la piscine est bleue.

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.
