  1. The huge size of those beams say they expect furter explosions or/and a major earthquake .

    But if that’s so , shouldn’t they expect as well the colapse of the Spent Fuel Pool , the water to drain and a start of Chernobyl-like nuclear fires ? We’ll see if they will install Water Pipes and Water Nozels on those beams as a preparation . If not , we’ll have something to speculate about …

  2. One level in almost 2 years. I hope the next 3 levels are installed faster so TEPCO can finally mitigate the danger here.

  3. lol. Joke mitigation at work. In some sense, better than nothing, though if greater urgency were made known, more lives would be safe. In this sense, Japan is like China. Lives are like dimes and nickels.

  4. The whole proposed new structure seems unstable , ready to topple , the size of those beams hanging over the SFP must put a lot of pull on the rest of the new structure that seats on the ground .

    Which brings us to how they fastened those huge beams to the existing pavement ? For such size one needs a Foundation of pilons but we didn’t see that . Is the new structure mounted on the ground using just bolts ?

    If that’s the case I bet the new stucture will topple on top of the SFP during a M8 because of the bolts being sheared ( the shear/scissor action acts on the weaker , cross section , of the special airplane-grade bolts ) .
    Iori , you are a civil engineer , what do you think ?

  5. Perhaps I am missing something here? Do I not recall that the ground under Number 4 Fuel Pool is subsiding, that it had subsided more than 80 cm some months ago and that is was still subsiding?
    So how does layering huge girders on either the building or the land that supports the land (poorly) help the situation, exactly?
    True, I am not an engineer so I may very well be missing something vitally important. It would really help me out if someone would explain it clearly and simply so that it actually made sense to increase the weight on failing terrain by a huge amount.
    Of course, all of this is only important because if the fuel pool collapses (as it may well do faster with extra weight on the ground there) the cataclysmic impact for the entire Northern Hemsphere (and planet) is beyound horrifying.
    Thanks in advace for the clarification.

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.
