    I have not been able to understand the reason for injecting nitrogen into the reactors for a blanket. I say reactors. I'm not sure where TEPCO is injecting nitrogen. I have seen nitrogen blankets used in tanks to prevent explosive fumes from collecting at the top of the tank. Nitrogen is heavier than hydrogen so it seems to me TEPCO is pushing the hydrogen to the top where it can mix with oxygen. Since the corium is out of the building, the reactor and containment is shot full of holes. Puzzling.

      as far as i know and i know preciously little about it, the nitrogen is also used to starve the corium of oxygen in order to starve the fire. this has been successfully used in the Windscale accident.

    If one looks at the chemical properties of Nitrogen. And if one looks at the nuclear configuration of Nitrogen. One must conclude that, if one must put something on the spent fuel or corium, it should be Nitrogen. It seems to be the lesser of 92 evils. Lucky number 7, crap. We lose.

  • Didn't hydrogen cause several of the other units to go 'poof'.

    Poof sounds much nicer than EXPLODE!

    Note: There is "no way" anybody human can even enter Unit #2 to truly ascertain what's going on.

    This should be the NBC/CBS Nightly News lead story followed by the "Special Report" of the Obama speech declaring a world emergency, how to take mitigation efforts and that there would be an immediate cessation of all Nuclear Power Plants under U.S. Control. (okay, I'm a dreamer)

    Wake up Brain Williams, Katie Couric… somebody speak up and do it NOW! Break the SILENCE! Don't let Katie scoop you Brian.

    There are hydrogen in the reactor building!
    This only means that there is something going on there that makes hydrogen H2.
    I spoke to an experienced nuclear power safety engineer last year after the explosions, and he had no clear idea where did all this hydrogen come from. There are three possibilities. 1. The zirconium shield around the fuel elements reacts with water at some higher temperature (not so high), and makes enormous amounts of hydrogen from the water. (a similar reaction if you let sodium or potassium metal in water). 2. Water dissembles into hydrogen and oxygen from radiation – so called radiolysis. And the third hydrogen can be dissolved from water at very high temperatures.
    So what we see here is a proof that there is some of these three going on. My guess is that it is radiolysis – and that it has become a re-criticality, water and fuel in a mix can start a chain reaction in some part of the fuel. When this happens, the power increases drastically. And also the radioactivity multiplies.
    There is also a spend fuel pool in this building. We dont hear much of it. But in there must also be fuel with zirconium shielding. If temperature rises in that of course enormous amounts of hydrogen can be produced.

    Thank you Urban27. That is way more analysis than we are getting from MSM … or from the nuclear shills at MIT, or from our friendly GE folk, where they designed and built these devices!!

    Has TEPCO tried a warranty claim, for defective manufactiring design? … which has cost them their whole country? …

    Hello! World? Anyone home?

    Peace everyone. Stay strong!

      Since they were using the reactors long past their use by dates as well as using fuel not specified in the original designs (MOX), I'd guess this will void any warranty claim. :)
