Tanks designed to hold radioactive filtrate at the Fukushima No. 1 nuclear plant are proving too fragile to be used, and the operator has announced a further delay in starting up machinery that cleans contaminated water.

[… It was] to begin operation at the plant in September.

[…] they are unable to predict when the equipment may finally come online.

The vessels are hoisted and lowered as they are filled and replaced by empty containers. In the event of an accident, they need to be strong enough to withstand a fall without releasing their radioactive contents.

TEPCO confirmed that the vessels could sustain a fall from a height of 6 meters in an upright position. But tests found the tanks were breaking and spilling their contents when dropped on from a height of only 3 meters in an upside-down position. […]

    Can anything we build survive an earthquake… I mean usually they level everything.

    • amberlight amberlight

      An earthquake doesn't need to level the structures in order to trigger a global end-of-life scenario. Right now, it's only a catastrophe, but the right amount of shaking up will turn the Fukushima Failure into an extinction level event.

      • Time Is Short Time Is Short

        "Right now, it's only a catastrophe, but the right amount of shaking up will turn the Fukushima Failure into an extinction level event."

        Oh, we're waay past that. It was an ELE on 3/11. The biosphere is accumulating over 100,000 Hiroshima-sized nuclear bombs worth of radiation per year, increasing exponentially. Life cannot withstand this.

        Any further serious degradation of the Fukushima architecture will simply increase the speed/rate at which all living life on this planet dies.

  • And I wonder if they remember that things freeze in winter, and that causes pipes and tanks to break…maybe that is beyond their "design basis"

    LOL, sick to my stomach

  • amberlight amberlight

    How would the tanks get tipped into an upside-down position? With 21st century "advanced" technology, they can't devise a way to lift and move the tanks securely? Oh, I forgot. Procuring state-of-the-art equipment would eat into Ineptco's profits…

  • WorkerBee

    The design basis is that the tanks will land upright and level and not on either a corner or an edge when dropped? Has TEPCO ever watched crane accidents on You Tube or dropped buttered toast? Why do I not feel warm and fuzzy about this level of engineering?

    use a rubber polymer rubber insulation wrap about 2 inches thick absorbs the vibrations
