Tepco doesn’t plan to build sacrophagus in Fukushima nuclear plant

On 6/6/2013, Fukushima decommissioning management team held a meeting for medium and long term road map.

The team consists of Ministry of Economy, Trade and Industry, Ministry of Education, Culture, Sports, Science and Technology and Tepco et al..

The newly published decommissioning plan revealed they don’t plan to build sacrophagus in Fukushima nuclear plant.

The decommissioning management team still sticks to removing molten fuel debris and fuel assemblies by building upper or entire containers over the reactor buildings.

They announced to start removing the fuel debris up to 1.5 years sooner than originally planned (12. 2021) at the soonest, most of the major media reported this since 6/8/2013.

However it is based on none of the new technical development.

According to their new plan, they are to start removing fuel debris from reactor1 in the last half of 2022, from reactor2 in the first half of 2024, from reactor3 in the last half of 2023 at the latest.

In any senario, building sacrophagus is not planned. The reason is not announced.

Tepco ne prévoie pas de sarcophage pour la centrale nucléaire de Fukushima


Le 6 juin 2013, l’équipe de gestion du démantèlement de Fukushima s’est réuni sur la feuille de route à moyen et long terme.

Cette équipe est constituée du Ministère de l’Économie, du Commerce et de l’Industrie, du Ministère de l’Éducation, de la Culture, des Sports, de la Science et des Technologies, de Tepco et all…
Le nouveau plan de démantèlement publié révèle qu’ils ne prévoient pas de construire de sarcophage sur la centrale de Fukushima.
L’équipe du démantèlement reste collée sur l’idée de retirer les gravas de combustibles fondus et les assemblages en construisant un cadre d’extraction et de transport des combustibles au-dessus des bâtiments des réacteurs, sur tout ou partie du dernier étage.
Ils annoncent qu’ils pourraient commencer au plus tôt à retirer les débris de combustibles jusqu’à un an et demi avant la date prévue à l’origine (décembre 2021), la plupart des grands médias le rapportent depuis le 8 juin 2013.
Ceci n’est cependant fondé sur aucun nouveau développement technique.
Selon leur nouveau plan, ils commenceront à retirer les débris de combustibles du réacteur 1 durant la 2e moitié de 2023 au plus tard.
La construction d’un sarcophage n’est prévue dans aucun de leurs scénarios. La raison n’en est pas donnée.

  1. So, basically this means it’s over? Reassembling, carrying around debris won’t help any. As far as I understand the situation, the radiation is still increasing. For machines it is already too much. For humans (like the liquidators of Chernobyl, rest in peace) it is becoming too much just the same. So this is it? People wait out until soon we pass the Point of No Return and then that’s it?

  2. TEPCO has no containment, a sacrophagus would be pointless unless for dust control but the majority of continuing radioactive fallout is from water contacting uncontained and melted fuel areas then flowing into the aguafiers continuing out to sea and can’t be stopped.

    How much radioactivity is available to continue poisoning the surrounding envoirnment? Unlimited amounts.

  3. But didn’t the sarcophagus of Chernobyl save a good part of the world from total meltdown? If in Fukushima there was a sarcophagus all around it would prevent water to get into water cycle and pacific? Of course there had to be no more water coolant system. In Chernobyl there was none to begin with and it worked combined with a sarcophagus. If a sarcophagus doesn’t work, then I don’t know what could work. They can’t get everything unstopped into environment. Can’t. That’s overkill.

  4. The sarcophagus of Chernobyl was an after thought, temporary,leaky and had nothing to do with stopping a meltdown. The meltdown there already happened when the reactor exploded sending most of the vaporized core airbone around Europe.

    The difference between Chernobyl and Fukushima is that with Chernobyl, they know where the lava remains of the melted core are. Flowed onto the lower floors until it cooled in place. The sarcophagus there is only to try and prevent radioactive dusts from leaving the building. The new sarcophagus will be airtight containment as they try to acutally remove the radioactive parts of the building and melted core.

    At Fukushima the melted cores still interact with groundwater, surrounding air and environment. Why? Because they are not sure where the melted cores are and/or even if they knew exactly where they were they can’t contain them, containment is lost on units 1,2 & 3. Worse, the melted cores still can react with water either to produce hydrogen and/or continue frizzling at will. At Chernobyl the melted core is high and dry. At Fukushima any water is free to carry off radioactive contamination.

    ‘Can’t’is realitive to the next 3 or 4 generations, if lucky. TEPCO can say what they want but you won’t be around to see the results of their predications.

  5. I may have phrased it wrong but still the sarcophagus limits the radiation causing material to a reginoal problem. It won’t poison the seas like it actually does and like you said it keeps materials where they can be found and however treated if we ever find a way to reverse. Which I hope very much.

    Without a sarcophagus the whole world will be increasingly contaminated with material that won’t last only for 3 or 4 generations. We talk about hundredthousand years in case of some of the Fukushima related particles…

    So I’m Not Here, as far as I understand we agree that environment isn’t save anymore. What are your measures to protect yourself? I don’t buy green tea, I don’t buy any Japanese traditional goods (it is hard), no rice, no black tea except it’s from India (good but still hurtful, I love Earl Grey). I try to buy only European vegetables and those not from South Germany or France. If I buy meat I get it from a local butcher from whom I know where his animals live. I get eggs from my city. And I watch out for sunflowers and dandelions so I can see when mutation is starting here, too.

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.
