    Yeah but come on, we've got unrest in the middle east, a failing economy, natural disasters happening like nobodies business, and now we've got what could be a nuclear disaster. They just all kind feels like things that happen right before a major ****storm.

    Simple - the time is up and the civilization is exhausted.
    Besides, we haven't reached Super Moon yet. We'll see. But better pray too.

    Rolfchopter, I do however wonder if this might have something to it know. I mean with the Haiti earthquake, and the Japanese earthquake it really makes me wonder along with the earthquake in Arkansas. My sister said that with the event in Haiti it messed up the plates a lot so we should here a lot more about earthquakes this year. Thought this is also probably due to the moon as well as it will be at it closet to earth in the coming week which can effect the earth in a geocentric stance but don't worry I am not saying it will cause catastrophic events but we might see a few strong earthquakes. This is one of the strongest since 1900's on the pacific coast which as a armature geologist I find this both sad and cool at the same time.

    Everything you just mentioned could be used to describe the 1970s and nobody would think twice about it.

    As GhostlyJoe said, the world has always been screwed up in some way or another. This is not something new.

    Maybe I'm just being overly-imaginative.

    Yikes... also, it is hard to see, but is the report also showing a graphic with 1400 dead so far??? this still has a lot of legs to it... this is bad... Given the winds in the region, the northwest coast of North America (including Alaska) and parts of Russia will have to keep an eye on this...

    Well, that's news. The maintenance technology for boiling water and pressurized water reactors is that required to keep water in pipes, with pumps and valves, too. That's reasonably simple tech and when proper maintenance and operational protocols are followed, safe and non-explosive.

    What's almost certainly happened in Japan is a complete loss of flow due to breakdown in the electrical system leading to a loss of coolant accident. This will pull a bubble over the core and the buildup of heat from fission product decay almost certainly cracked the H2O into a gaseous mixture of hydrogen and oxygen. That was the biggest concern at Three Mile Island, and the US didn't have a megaquake shaking their reactor to pieces.

    So the bubble probably burst, and that was because the japanese didn't engineer their reactor to handle such shocks.

    Oops.

    Nobody in their right mind uses hydrogen to cool anything. Outside the expense of making the hydrogen in the first place, it's not an optimal coolant.

    WATER, that's what's used practically everywhere, cheap, accessible, chemically benign, simple to handle.

    Edit:

    in certain circumstances hydrogen is a desired coolant. Like for the combustion chamber cooling fluid in rocket engines...which serves to preheat the hydrogen and ensure it's vaporized before combustion.

    But it's not a routine thing, and it's fraught with hazards.

    can't agree with your diagnosis
    engineering the facility to withstand shocks of an earthquake does not appear to be the problem
    losing power - resulting from the flood waters knocking out the power system to cool the reactor - was

    I've lived a long time, seen a lot of scary sh*t happen around the globe, but this quake/tsunami/nuclear disaster in Japan is the worst natural catastrophe I've seen. 10,000 people are missing, well over a thousand confirmed dead, three nuclear workers are confirmed to have been contaminated with radiation... My god, that poor country.

    Edit: I should back up a bit and acknowledge that the overall devastation and immense loss of life caused by the Indonesian tsunami was worse, but the potential destruction by Japan's nuclear meltdowns could potentially be much worse, and spread the result globally.
