On 10/29/2015, Tepco announced they measured 9.4 Sv/h in Reactor 2.
The measurement point was outside PCV 2 (Primary Containment Vessel of Reactor 2) to show the possibility that the molten fuel has leaked out of PCV 2.
This investigation was implemented this September. Tepco was planning to inspect the inside of PCV 2 this August by sending a robot from a penetration pipe, but it was suspended due to the excessively high level of radiation.
Le 29 octobre 2015, Tepco déclare avoir relevé 9,4 Sv/h dans le réacteur 2.
Le point relevé est en dehors de la PCV2 (Primary Containment Vessel of Reactor 2 = enceinte de confinement primaire du réacteur 2) pour établir si le combustible fondu avait fuit hors de la PCV2.
Cette recherche date de septembre dernier. Tepco prévoyait d’explorer l’intérieur de la PCV2 en août dernier en envoyant un robot par un tuyau de pénétration mais ils ont arrêté à cause d’une radioactivité trop intense.
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.
