    @korvelo Robots don’t work in high levels of radiation it eats their circuits. They tried that at Chernobyl. Just saying

    @endthedisease japan doesnt need solar energy to be a renewable energy country. They live on the pacific ring of fire. You would obviously use Geo-thermal. much better than solar energy.

    some of the things those rods are made up of dont become non radioactive for 240,000 years, now thats scarry, someone needs to get in there and get those damm things cooled down again

    @TheEgg185
    if the pressure in the tank is high(overheating), boiling point is also getting high and less evaporation. But too high pressure makes pouring work hard. Engineers are measuring best point of pressure and temperature by manual or physical work.

    @TheEgg185 If you’re referring to the 3rd safety mechanism this is the reason for the continued overheating:

    The 3rd safety mechanism is supposed to cool down the rods using the evaporated water which is then condensed and send back. This failed because of the mere reason that; at this point when the 2 other safety mechanisms failed, the rods were too hot for the condensing proces to catch up. The water evaporated faster than the condenser could cool down the steam again.

    This was a self-inflicted problem, due to poor engineering and poor leadership.

    Now the solution is a “SIMPLE ENGINEERING PROBLEM” and the proper leadership.

    They must make/adapt robots and unmanned vehicles to go there and either fix the problems, or remove the fuel rods to a temporary pool!……….This simple.

    Money not being a problem, this could be solved in 2 weeks or less by a team of 1000′s, working 24/7.

    They can contact me for the details!

    @TheEgg185 – Nuclear fission doesn’t produce completely stable atoms, these atoms undergo further decay until they reach a stable state. While this decay occurs, heat is produced. Immediate decay heat from a long running nuclear reactor can be about 8% of the reactors usual power. In a reactor that producded around 2,000 Megawatts thermal, this still a really large amount of power.

    @sagorevach i think that would be possible for u but it is impossible for most of people nowadays. They don’t really care if it safe or not, as long as they have enough power to waste.

    there’s a leakage thats why water does not stay inside and the rods remain overheated.

    @Arxidianomeas The reactors went into SCRAM mode when the earthquake struck. Control rods were inserted and the fission reaction ceased, meaning the reactors were in fact “shut down”. NOW the problem is, the nuclear fuel rods are still highly radioactive which in turn produces extreme heat and the rods can still meltdown without coolant. Even “spent” fuel rods that are no longer usable still produce massive heat. Thus they have to be stored in cooling ponds for up to several years.

    @Arxidianomeas even if you covered the whole town with solar panels it wouldn’t put out %10 of the energy that the nuclear plant did. Probably not even %5

    @sagorevach wind and solar energies are good alternatives IMO.

    @Arxidianomeas they turned off reactors but they can`t shut it down like it`s computer. Inside the reactor the fuel still had high temperature and cooling system failed… and that`s it. If cooling systems didn`t fail, nothing would happen. Temperature would be decreased and safe. Maybe we should take this as warning and lesson for every country to never build nuclear plant EVER again and to shutdown every plant in the wolrd. I`d rather live in a dark but healthy and alive. God help you Japan

    But hang on a second ?
    Didn’t they stopped the process after the earthquake ?
    Didn’t they pushed a “shut down” button that would stop the whole process that heats up the bars ?

    Japanese authorities have told the U.N.’s atomic watchdog they are making preparations to distribute iodine to people living near nuclear power plants. Concerns about the nuclear situation in Japan have sparked runs on iodine tablets in places as far away as Finland. (Finnish pharmacy reps said that some of their stores in central Finland ran out of iodine completely on Saturday.)

    wow. this video explains a lot. the news doesnt explain shit. i have so many questions they’re not answering. one thing THIS video doesnt explain is why the thing is STILL overheating even with the sea water????
