Tepco to dismantle the entire roof of Reactor 2 / “Largely emits radioactive material but fast”

On 11/26/2015, Tepco and METI (Ministry of Economy, Trade and Industry) announced they plan to dismantle the entire roof of Reactor 2 building.

This is to remove the nuclear fuel stocked in the SFP 2 (Spent Fuel Pool of Reactor 2). It is reported that it stores 587 spent fuel assemblies and 28 new fuel assemblies. The pool is located on 5th floor. They plan to remove the entire wall and roof above the floor.

They commented that the construction is going to start in the end of 2016, but the exact date is not announced yet.

Tepco turned down all the other ideas to remove only a part of the roof in order to minimize the radioactive material that can be spread out. They state it is because the estimated construction duration is the shortest.

Tepco va démanteler l’ensemble du toit du réacteur 2 : “Importante dispersion radioactive mais courte”


Le 26 novembre 2015, Tepco et le METI (Ministère de l’Économie, du Commerce et de l’Industrie) annoncent qu’ils prévoient de démanteler l’ensemble du toit du bâtiment du réacteur 2.

Ceci en vue de retirer les combustibles nucléaires encore stockés dans la SFP 2 (Piscine à Combustibles Usagés du réacteur 2). Il est dit qu’elle contient 587 assemblages usagés de combustibles et 28 assemblages neufs. La piscine se trouve au 5e étage. Ils prévoient de retirer tout le toit et les murs de l’étage.
Ils déclarent que ce chantier commencera fin 2016 mais que la date exacte n’est pas encore fixée.
Tepco a écarté toute idée de retrait partiel du toit pouvant limiter la quantité de matières radioactives qui vont se répandre. Ils affirment que la durée du chantier est la plus courte possible.


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.
