Fukushima worker “Human-wave tactics will be needed, problem is if they can collect human workers”

Following up this article..Fukushima worker “Shortage of nuclear worker is becoming serious”


Having finished the radiation survey in reactor1 [Link], actual Fukushima worker Happy11311 tweeted like these below,,




Tepco conducted the robot survey of reactor1 as they announced yesterday. We haven’t received the details of data (Tepco had not published the data at this time) yet, but sounds like the radiation level was high as usual. It was 4000mSv/h around where the steam was coming up from the pipe sleeve on the South-East side of the building last year.

*It was not 4000mSv/h, but 5000mSv/h. He misunderstood the number.





Maybe it was 4700mSv/h last year, so it slightly decreased (* Because it was actually 5000mSv/h, it slightly increased. He misunderstood the number.) but human can never approach it yet. Today robot didn’t work at the beginning, the ending time was later than they scheduled. Anyway, we must rely on the robots at the highly contaminated places in reactor building for a while.





Anyway, there are still a lot of highly radioactive places where human workers have to go. Probably we must take the “human-wave tactics” where is about 100 ~ 120 mSv/h. but the problem is if we can collect enough human workers, even now sub-contract companies are struggling to collect nuclear workers.

    Ayant fini l’exploration du réacteur 1 sur sa radioactivité, Happy11311, le travailleur à Fukushima, a tweeté :

    (Traduction) Tepco a dirigé le robot d’exploration dans le réacteur 1 comme ils l’ont dit hier. Nous n’avons pas encore le détail des résultats (Tepco ne les a pas encore publiés) mais on parle de hauts niveaux de radoactivité, comme d’habitude. On avait 4 000 mSv/h autour, par où la vapeur sortait de la manche du tuyau au Sud-Est du bâtiment l’an dernier.(Fin)

    *Ce n’était pas 4 000 mSv/h mais 5 000 mSv/h. Il a mal compris le nombre.

    (Traduction) Peut-être était-ce 4 700 mSv/h l'an denier, alors ça a un peu diminué (*parce que c'était 5000mSv/h, ça a un peu augmenté, il a mal compris le nombre) mais les humains ne pouront jamais s'en approcher. Aujourd'hui le robot n'a pas marché au départ, l'opération a pris fin plus tard que prévu. De toute façon, nous devons nous appuyer sur les robots pendant un moment pour les endroits hautement contaminés du bâtiment du réacteur.(Fin)

    (Traduction) De toute façon, on a toujours un paquet d'endroit hautement radioactifs où des travailleurs humains doivent aller. Nous allons probablement devoir appliquer la "tactique des vagues humaines" là où on a 100 à 120 mSv/h mais le problème est de savoir si on va pouvoir recruter assez de monde pour ça, même les sociétés sous-traitantes se battent pour trouver des travailleurs du nucléaire à présent.(Fin)

  2. NOBODY should join any wave effort until Japan FIRST renounces nuclear power and decommissions ALL of its nuclear reactors. So long as Japan continues to operate nuclear reactors, any sacrifice of life in fixing TEPCO’s Fukushima disaster would be pointless.

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.
