    NRC has been routinely relicensing aging nuke plants so utility won't have to pay to decommission them. All this does is increase the risk of broken nuke accidents. Do we have to lose a state or two to make the NRC see how foolish this is?

    Reactors have broken like glass during the accident at Fukushima Npp.- Neutrons change the properties of steel.

    Only new reactors?
    Ya..right..

    This is why Arnie Gundersen has been raising the red flag on re-liscensing nuclear power plants beyond 40 years.

    The NRC and the Obama administeration are criminals for pushing these designs beyond the breaking point.

    Test projections don't predict real life findings, no problem, blame the test projection procedures and declare the reactors safe to operate based on previous experience. No sense in using fact finding to discover safe working parameters, might have to shut down and decommission using bona fide figures. Keep running tests to get results in your favor.

    This is the exact same reason that nuclear waste can't be stored safely for very long. The radiation breaks down the materials surrounding it. Besides that what other material lasts for 24,400 years, which is just the halflife of plutonium?
    Let's face it, unless we can find a safe way to send nuclear waste into space, we're doomed.
    Consider it a fact that the bastards have killed us, and all other living thing on this planet. But don't blame anyone but yourselves. Remember; You let this happen. You were the one who was thinking that you were to busy, and someone else could take care of it.

      @Gnyf: there is a safe way of moving high-level nuclear waste into space, which is then pushed into the sun…

        My son was touting this exact same solution but I said what if it fails and falls back to earth but I guess it is certainly worth a try what other solutions are there.

          it is totally doable moonshellblue. I've outlined a process for how it would be done. It would require the cooperation of all nations.

          The only reasons it wouldn't 'fly' will be do to a lack of support from the nuclear power crowd; who'd be reluctant to acknowledge the problem and incumbent expense. The other impediment is in garnering public support. Given the horrendous history of those who have handled these materials in the past, most people would be suspicious of supporting such an effort. I've developed the process flow of material handling that ensures its safe transfer, from source point to final destination in space. I've even worked-out how to alleviate failed launches and the recovery of 'payloads'. I could go on…

          • What is your method? Has it been published and reviewed throughout the world?Have an online gate for viewing it? What has been the critique of your method by adversarial agents? America is known to succeed in complexity due to adversarial expertise so they can vastly improve their designs. In view of the felt critical nature of the proposal people like Gates may be open!

      Thoughts of sending nuclear wastes into the space sounds scary to me. In theory, it sounds good but tons of highly radioactive (even encased in a heavy lead/steel casing) wastes could malfunction the circuit boards and computer parts, what if it don't make it to the space and something happens in the air. It's like shooting up a….nuclear weapon to explode…precisely. :O

        your fears are not unfounded GlowInTheDark. The solution rests in how the waste is processed. There's a way to process the material to make it inert; thereby making it 'safe' for recovery if there's a 'launch' failure. Such a remediation project has to factor failed transfers into space, if it's to be successful. Anything less is playing with fire. And this process is not-only fault tolerant, it's also cost-effective…

      Hey Gnyf…Don't include me in your "you" accusation of letting this happen. I've been protesting nukes since the mid 1950s. Did all I could, including blaming others for not joining me. Just sayin'–Careful you don't blame with too broad a brush!

    Maybe taking it to study for 'cracks'.

    I don't think this was an 'advertisement' opportunity like some may have suggested.

    I think it was a statement by the workers of Fukushima Daiichi pointing out some of those who ARE responsible for this world changing historic mega catastrophe.

    …makers of the 'cannot be breached' containment vessel.
