On 10/30/2014, Tepco announced they postponed removing molten fuel from Reactor 1 until 2025, when is 5 years later than planned.

Currently Tepco is trying to remove the existing cover, but this is already 6 months behind the schedule.


Their delaying the schedule is due to the change of fuel removing process.

Originally they planned to remove the fuel from Spent Fuel Pool 1 by transforming the existing cover. In the revised plan, they are to build a new structure over Reactor 1 like Reactor 4. Also, in order to remove the molten fuel, they are to replace the cover again.

After all, fuel removal from Spent Fuel Pool 1 is going to be postponed by 2 years, molten fuel removal is going to be postponed by 5 years.

However, neither of the state nor the location of molten fuel is verified. They rescheduled the plan but it is still baseless.


Tepco states the entire decommissioning will be still ending in 30 ~ 40 years, but this is also baseless. The actual decommissioning may take over a century.

Le 30 octobre 2014, Tepco annonce qu’ils repoussent le retrait des combustibles fondus du réacteur 1 jusqu’en 2025, soit 5 ans plus tard que prévu.
Tepco essaye actuellement de retirer la toiture existante mais c’est déjà avec 6 mois de retard sur le planning.

Leur report de calendrier est du au changement de méthode de retrait du combustible.
Au départ, ils avaient prévu de retirer les combustibles de la piscine du réacteur 1 (SFP1) en transformant la toiture existante. Dans leur planning révisé, ils vont construire une nouvelle structure par dessus le réacteur 1 comme avec le 4. De plus, ils vont refaire encore une fois la couverture pour pouvoir enlever le combustible fondu.
Au bout du compte, le retrait des combustibles de la piscine à combustibles usagés du réacteur 1 (SFP1) est repoussé de deux ans et celui des combustibles fondus de 5.
Néanmoins, ni la localisation, ni l’état des combustibles fondus ne sont établis. Ils ont revu leur calendrier mais c’est toujours sans fondement.

Tepco affirme toujours que le démantèlement complet sera terminé d’ici 30 à 40 ans mais c’est également au pif. Le démantèlement réel peut très bien demander plus d’un siècle.


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.
