Tepco “Molten fuel may be in various parts of reactor, takes up to 35 years to remove, international help is needed”

Tepco "Molten fuel may be in various parts of reactor, takes up to 35 years to remove, international help is needed"

On 2/21/2013, Tepco released their report that was submitted to IEM held by IAEA from 1/27 to 2/1/2013.

In this report, Tepco admitted, they cannot deny the possibility that molten fuel debris were scattered to recirculation pipes, suppression chamber or torus room.
(cf, [Column] 3 facts to support the hypothesis that fractured nuclear fuel is in individual stages of nuclear reaction [URL 1])

They estimate the defueling process takes up to 10 years to start and up to 25 years to complete.
In the end report, they are asking for the international advice and counsel.

Tepco : Le combustible fondu peut être éparpillé dans le réacteur, 35 ans pour l’en retirer, l’aide internationale est requise

Tepco "Molten fuel may be in various parts of reactor, takes up to 35 years to remove, international help is needed"Le 21 février 2013, Tepco publie le rapport qu’ils avaient communiqué au cours du meeting international (IEM) de l’AIEA qui s’est tenu du 27 janvier au 1er février 2013.

Dans ce rapport, Tepco admet qu’ils ne peuvent nier la possibilité que les débris du combustible fondu soient éparpillés dans les tuyaux de recirculation, la chambre de surpression ou celle du tore.
(cf. [Édito] 3 faits soutenant l’hypothèse que les débris de combustibles sont en différents états de réaction nucléaire)

Tepco : Le combustible fondu peut être éparpillé dans le réacteur, 35 ans pour l'en retirer, l'aide internationale est requise

Ils estiment que le processus de retrait du combustible pourrait prendre jusqu’à 10 ans pour commencer et jusqu’à 25 ans pour se terminer.
A la fin du rapport, ils en appellent à des conseils et avis internationaux.

  1. Well it’s about freakin time tepco calls for international help.

    It’s taken 2 years for them to ask and the “international community” has been sitting on their hands for the last two years and ya gotta wonder why.

    Keep in mind folks, the Soviets had the sarcophagus built over Chernobyl within 280 days of the accident; we’re approaching day 730 here in a couple of weeks in Fukushima.

    Hope you’re well Iori.

  2. Solution : burry it deep in the ground

    How , for this particular case : subway trains tunels of wide diameter have been drilled horizontally . This time do it Vertically and right bellow the reactor .
    Once the 500 meter deep hole is drilled and stabilized , blow-up the layer of earth used to separate the tunel during digging , and let the entire reactor drop deep inside the tunel . Then cover it up with appropriate agregate .

    Matter of fact , if the Nuclear Barons will sucede in building more reactors , than it should be applyed the new standard of having a wide-enough and one kilometer deep hole with a ‘mouth’ just below the reactor , designed to guide the Melt in case of structural damage and breach of reactor containment vessel .

    But … they can’t even figure out if a G-D silly thermometer works or not ! The Planet of the Apes Disney Land !

    1. Iori , you are a civil engineer so you can have a professional opinion about the 500 to 1,000 Meters vertical hole under the reactor as an emergency drop-and-burry-in-a-hurry ( DEBUH ) device .

      I didn’t address the ground water because it can be contained during drilling OR beter yet , the location of the reactor should be choosen to avoid it .
      The aggregate to cover it , as a stand-by hill with remote-controlled belt-delivery ( conveyor belt ) machinery , should be determined too .

      Like it ? Than send it to the Govern-ment and the Media + the international ‘body’ .

      Oh , Did you find a Translator yet ?

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.
