N-fuel pool, ruined structure seen up close
The Daily Yomiuri
May 28, 2012

Goshi Hosono, the nuclear disaster management minister, spent half an hour Saturday inside the Fukushima No. 1 nuclear power plant’s No. 4 reactor building [...]

Hosono was accompanied by four representatives of the news media. [...]

On the fifth floor, the group inspected the surface of the pool, in which 1,535 rods are stored–equivalent to the number necessary for three reactors. The rods are kept seven meters below the surface. Due to poor transparency and no lighting in the water, the rods were not visible when a sheet covering the pool was removed.

In addition to the four members of the press accompanying Hosono, a Yomiuri Shimbun reporter and other journalists were allowed to look at the building from much closer than before. [...]

  • Question

    (sorry: re-posted from discussion forum)

    I have screen shots of unit 4 from the TBS-JNN cam. In these shots it appears that one can see through the building to the ocean.

    Second, I've screen shots of the #4 building that depict collapsed walls.

    These same walls appear intact in the recently released images of building 4

    For instance, the screen shots I have look NOTHING like this shot from NHK
    http://www3.nhk.or.jp/daily/english/20120528_09.html

    Has anyone else noticed the disconnect?

    Can anyone offer an opinion on this?

    Why do the images look so different?

      Hi majia, Whoopie posted new pics from cryptome.org yesterday. There are barely wall structures left, so yes, from the right angle you could surely see through to the ocean.

      That's a picture of the spent fuel rod pool shot from above. It's not the ocean.

      Also, the pictures NHK used in their report were the pictures from the internal pool examination done earlier. Since there wasn't a similar examination done yesterday, they used the pictures they had on hand while discussing the fuel rods. There's nothing strange about it. All news organizations run images they have multiple times until they have new ones to replace them.

      Smokingsess, it's not that some of the assemblies are empty. The assembiles have covers placed on top of them when they're put into storage. Some were shaken off either by the explosion or earthquake. That's what you're seeing in the video.

    It was so clear that the assemblies were (partially) empty. Why else should Tepco cover it with a sheet? To hide something. Same as Unit 1.
    There was definitely a critically in SFP 4 and no Hydrogen-Gas coming from pipes by unit 3 – BS.

    Tepco, we have the right to know if our health gets affected by your failure. I hope you will burn in hell for that.

    The usual mistake citing the number of fuel rods, when the number refers to fuel assemblies and there were actually closer to 100 times the number of fuel rods as these BWR took some 93 fuel rods per assembly according to some accounts.

      In modern BWR fuel bundles, there are either 91, 92, or 96 fuel rods per assembly depending on the manufacturer.

      1976: Falsification of safety records by TEPCO
      “The Fukushima Daiichi nuclear power complex was central to a falsified-records scandal that led to the departure of a number of senior executives of TEPCO. It also led to disclosures of previously unreported problems at the plant,[49] although testimony by Dale Bridenbaugh, a lead GE designer, purports that General Electric was warned of major design flaws in 1976, resulting in the resignations of several designers who protested GE's negligence.[50][51][52]…

        “Physicist Amory Lovins has said: "Japan is poor in fuels, but is the richest of all major industrial countries in renewable energy that can meet the entire long-term energy needs of an energy-efficient Japan, at lower cost and risk than current plans. Japanese industry can do it faster than anyone — if Japanese policymakers acknowledge and allow it".[285] Benjamin K. Sovacool has said that, with the benefit of hindsight, the Fukushima disaster was entirely avoidable in that Japan could have chosen to exploit the country's extensive renewable energy base. Japan has a total of "324 GW of achievable potential in the form of onshore and offshore wind turbines (222 GW), geothermal power plants (70 GW), additional hydroelectric capacity (26.5 GW), solar energy (4.8 GW) and agricultural residue (1.1 GW)."[406]…”
