Work to reinforce No.4 reactor building starts soon, hoping done by August — To prevent bottom of spent fuel pool from falling out

Work to reinforce No.4 reactor building to begin, NHK, May 23, 2011:

Work is beginning on Monday at the Fukushima Daiichi nuclear plant to reinforce the structure supporting the No.4 reactor’s spent fuel pool.

Tokyo Electric Power Company, the plant’s operator, says the work is necessary to install a cooling system for the stored spent fuel. […]

TEPCO’s plan calls for building a new concrete structure under the pool to prevent its bottom from falling out. […]

TEPCO says it hopes to erect the columns next month and complete the reinforcement by the end of July. […]

Previous reports on the structural integrity of Reactor No. 4 include “Very, Very Serious”: Unit No. 4 leaning, in danger of falling — Gov’t confirms stabilization efforts underway (PHOTO & VIDEO) and TEPCO discusses installing structure to support No. 4 spent fuel pool from underneath

  • Poor Daddy

    What a relief! After August, all we’ll have to worry about is #1, #2, #3, #5 and #6, and maybe the Tsuruga plant.
    Wonder why we can’t make energy conservation, or even rationing as part of the national conversation? Probably not as painful as cancer.

    • Poor Daddy

      Make that part of the GLOBAL conversation.

      I sad to report that everyone I talk to they not concern. They say you over react to three melt down. No problem they say. No scare the women and children. See nice day. Everything same. No problem.

      No more baby can have. Very bad for everyone.
      Fish poison, very bad. Rice poison, very bad.
      Air very bad. Baby die, very bad.

      Sorry I think I will move now.

  • Jean Tanner

    Let’s hope they can finish this before the typhoon season sets in.

    • Cindy

      I was thinking they finish before the next large aftershock.. They should have already started the work. Maybe they figure if it has held for 2 months , it’ll be ok until they get to it ….

      • Jean Tanner

        Given the radioactivity as reported in the area and the scope of the proposed solution, I’m surprised TEPCO is starting the work so soon.
        But then, my opinions are based on what I read here, at NHK, at BNC and EX-SKF’s blog.

  • Watt

    What would happen if the bottom falls out?

    • glenn

      We’ll find out 2 months later and there’ll be no ‘immediate’ health risks. (pfff)

    • Steven

      1535 fuel rods (unfortunately not all ‘spent’, because relatively fresh rods, unsure of the number, probably anywhere from a third to half, a reactor load in fact, were moved there from the reactor for regular maintenance prior to the earthquake/tsunami) fall out into the general debris and people run away, and stay away.

      You can probably figure the rest out.

    Looking at the way reactor 4 building is at the moment, a decent fart could bring it tumbling down.

    Nuclear Inspectors Arrive in Japan to Probe Fukushima Accident
    International nuclear experts have begun arriving in Japan to probe the causes of the Fukushima nuclear disaster and make recommendations to prevent future accidents.

    Six experts from the International Atomic Energy Agency arrived in Japan Monday from the agency’s headquarters in Vienna. They will be joined by another 14 experts from 12 countries for an investigation that will begin Tuesday and run through June 2.

    The experts, led by British chief nuclear bullshit inspector captain Mike anyone seen the core Weightman, will spend most of their time in a 5 star hotel in Tokyo. they are expected to visit the Fukushima nuclear plant if it still exists by june.
    mike stated he would like to send his pa sooner to the slightly damaged plant, but she has to stay with me for sex and taking notes as we have much to talk about with old friends.
    mike also stated that the hotels spa area is just great and is looking forward to hitting the roppongi ladyboy bars later tonight.
    this sure is better than working in an office in the uk, correcting down uranium,plutonium discharge figures for Sellafield MOX Plant.
    it was also stated depending on the expenses and roppongi situation, the investigation into this extinction level event could take a little longer.
    when asked which one of the thunderbirds puppets mark liked best, he said brains cos that’s the part that always hurts me most.

    in celebration of mike and his teams heroic talking and chit chat work,here is a little clip.

      They are not experts if they cannot manage the outcomes of their industry. They lack any demonstrated ability or willingness to do whats needed when its needed. If they were true experts they would advise and help Japan eliminate this problem. They are are *experts* at boiling water in a stupid and dangerous way. I think I am pissed at the nuclear industry today again.

      • Jack

        I’d hope that somebody in Yakuza would kidnap
        the IAEA contingent and deliver them directly to the reactors for
        their “Inspection”. Hard to believe Mikey would expose himself to any

    • misitu

      lol well said

  • Dr.Stranglelove

    Shoring up the gates of Hell with balsa wood.

  • Regrettably, compressive load bearing of balsa insufficient for 135 tons of hot rods {8> – even WaPo published that one ( then ‘lost it’ so it ended up here:-

    The total tonnage of spent rods at Fukushima is utter insanity. Pray for the people of Honshu.

    Condolences go out also to residents of Joplin…latest victims of ‘climate change’ or perhaps Zhirinovski?
