Japan Nuclear Operator Postpones Plan To Flood Reactor Vessel, Dow Jones, April 28, 2011:

A plan to flood the containment vessel of one of the reactors at the stricken Fukushima Daiichi nuclear complex to better cool off its nuclear core was postponed Thursday, as concerns about possible leakage in the vessel made workers cautious about filling it with tens of thousands of tons of water. […]

A test run for an operation to flood Reactor No.1’s containment vessel began Wednesday morning[…]

The trial run saw a more-than-anticipated drop in the temperature and the pressure inside the reactor, raising the possibility that adding water could deflate the containment vessel too much, allow the atmosphere to enter, and spark a hydrogen-oxygen explosion similar to ones that hit the plant in the first week of the crisis in March. […]

    “Ok, we are now admitting that plan was stupid. It was submitted by Mrs. Hashimoto’s First Grade Class and it was a good try. Keep thinking up new ideas for us to try and send them in, right away!”

    wait a minute..it was cooling and the pressure dropped….isn’t that the whole idea

    • HARRY you been clubbing too much or clubbed. The pressure rose in effect creating hydrogen. This is no better then NUKE the friggn place now. We can die faster which I would prefer. Then uglying out of this world. Blow it up then deal with it. Or Cover it in Concrete and let it burn down to water and blow up. Then deal with it. I see a win win for HOMER SIMPSON only.

        succinct analysis. this is only the beginning of a nightmare of gigantic huge orwellian proportions.

    They have a dilemma. If they DON’T flood it, there will certainly be a meltdown.
