Tepco failed in TIP pipe soundness inspection in reactor2 again

Tepco failed in TIP pipe soundness inspection in reactor2 again

Since 7/8/2013, Tepco has been trying to inspect TIP guide pipe soundness in reactor2 but they failed with all of the 4 cable lines.

It was the second attempt to follow their inspection of February.

Tepco lost another clue to know what is inside of reactor2.

Since 7/8/2013, Tepco has been inserting 4 cable lines into TIP (Traversing In-core Probe) guide pipe of reactor2 PCV.

Tepco found unverified substance (~ 0.2 Sv/h, γ&β) on the top of the 4 cables but they couldn’t have a cable reach longer than 9.6m.

They don’t have a next plan yet.

Tepco échoue encore une inspection de la fiabilité du tuyau du TIP du  réacteur 2


Tepco failed in TIP pipe soundness inspection in reactor2 again

Depuis le 8 juillet 2013, Tepco essaye d’inspecter le guide de TIP du réacteur 2 mais ils ont échoué avec 4 câbles.
C’est leur deuxième tentative de reprendre les inspections depuis celle de février.
Tepco perd un autre moyen de savoir ce qu’il y a dans le réacteur 2.

Depuis le 8 juillet 2013, Tepco a inséré 4 câble dans le tuyau-guide du TIP (Traversing In-core Probe = sonde traversière du cœur) de la PCV2 (Primary Containment Vessel of Reactor2 = Enceinte primaire de confinement du réacteur 2).
Tepco a remonté une substance inconnue (~ 0.2 Sv/h, γ & β) au bout de leurs 4 câbles mais ils n’ont pu aller au delà de 9,60 m.
Ils n’ont pas encore de nouveau plan.

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.
