[Express] “It took 160 people, cost 4 million yen to tighten a screw of a nuclear plant”

Introducing an important tweet as [Express] for simultaneous update.


Once a large screw became loose at a running nuclear plant. When a nuclear reactor is generating power, the radiation level is extremely high, so 30 workers were prepared to tighten the screw. They were queued to run for the screw 7 meters away one after one.


The dosimeter beeps when you get to the screw and count 1, 2, 3. Some of them had the dosimeter beep before they even found a wrench. Only to tighten the screw required 160 workers and 4 million yen in total.

Une fois, un gros boulon s’est un peu dévissé dans une centrale nucléaire en activité. Quand un réacteur nucléaire produit de l’électricité,  le niveau de radioactivité est extrêmement élevé, donc 30 ouvriers ont été préparés pour resserrer le boulon. Ils ont été mis en file pour courir vers le boulon à 7 m les uns des autres.

Le dosimètre bipe quand vous approchez du boulon et compte 1, 2, 3.  Certains d’entre eux avaient leur dosimètre bipant avant même de prendre une clé. Pour resserrer le boulon il a fallu 160 ouvriers et 4 millions de yens au total.

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.
