TEPCO to begin operations to prepare for spent fuel removal at Reactor 4

TEPCO released plans for workers to begin preparations for more intensive work at the Number 4 reactor. Experts around the world have warned of the extremely compromised state of the damaged building that holds over 1,500 fuel rods.

As reported last week, TEPCO will begin attaching a special crane to take the fuel out of the pool and constructing a cover to prevent the spread of radioactive materials from the building. The cover will be 31 meters long and 69 meters wide and 53 meters high.

At Reactor 1 the cover was constructed to enclose the entire reactor building, however at Reactor 4, the structure will cover only the upper part of the pool for the reactor.

The cover is expected to be completed by autumn next year. Spent nuclear fuel will then be removed from the pool and stored on the plant compound.

    TEPCO is NOW Putting Life on Earth at RISK…

    If the SFP (Spent Fuel Pool) in #4 collapses or fails to be kept cool FOR ANY REASON, in a very short time, all the fuel rods in it will destroy themselves by becoming a huge molten mass. This new radioactive mass will make the ENTIRE Fukushima complex (including reactors #5 and #6 (and their SFP’s) into not only the Worlds biggest nuclear disaster but it will be so radioactive that the entire complex will be off limits to humans! This new uncontrollable molten mass will spew so much radioactivity (and keep doing so for the rest of our lives) that it will change life as we know it, because it will be spread Globally by the jet stream and or Ocean currents.

    BTW: If you have not seen the 1959 movie “On the Beach” you should, it describes a very similar situation…

    TEPCO MUST DO 3 THINGS ASAP TO PREVENT THIS:

    1. TEPCO should be filling the entire #4 building with concrete ASAP in order to create a “Seismic Vessel” to completely encapsulate the SFP making it impossible for it to collapse, because the new “Seismic Vessel” would be one gigantic unit…

    2. TEPCO should have no less than 4 backup generators and 4 pumps that EACH could provide ENOUGH emergency power and water should ANYTHING happen to prevent the normal pumps from functioning. Note this includes protecting all the fuel, storage tanks, piping and controls so that it would make these pumps and their generators completely BOMB PROOF so nothing could prevent them from functioning 24/7/365 and then TEST ONE UNIT EVERY DAY UNDER ACTUAL LOAD, so that the on site workers become expert at shifting pumps!

    3. TEPCO should build and then fill enough tanks to provide standby cooling freshwater for at least one week, so that no matter what happens, the #4 SFP will be kept cool without using seawater, (which could serve as another backup source of water) if the freshwater proved to not be enough for some unknown reason!

    I think the design of the new steel addition to SFP #4 will act like a can opener if there is a BIG Quake and actually make thing worse!

    I challenge TEPCOP’s structural Engineers to produce a software simulation for a 9.0 quake strike Fukushima…

    Then do the same thing after modeling filling the SFP complex with concrete making the SGP a huge “block” as I mentioned in my comment above…
