What is the solution to the nuclear power station fiasco in Japan? We all wonder why the hell the diesel generators failed when they surely should be encased in a very sturdy enclosure. Was the generator's exhausts the weakness do you think? How do they move forward? The water needs to get into the reactor core. I suppose their setup isn't designed for modern cooling fluids as such. Is there a danger of a meltdown melting radioactive material down into the earth, through the crust? What under ground cooling sytems are they likely to have in place anyway? Do they need to crane some big structures back over the reactors (where buildings have now gone) and vent the hydrogen into the ocean. Could this help to prevent the ejection of heavy radioactive material into the atmosphere? Would forest firefighting planes be of any use if the reactors did meltdown, in stopping said ejection? Lastly. Do you guys think that if one reactor meltsdown the whole lot are bound to follow?
