How To Take Apart Fukushima's 3 Melted-Down Reactors 167

the_newsbeagle writes "In Japan, workers have spent nearly three years on the clean-up and decommissioning of the ruined Fukushima Daiichi nuclear power station. They only have 37 years to go. Taking apart the plant's three melted-down reactors is expected to take 40 years and cost $15 billion. The plant's owner, TEPCO, admits that its engineers don't yet know how they'll pull off this monumental task. An in-depth examination of the decommissioning process explains the challenges, such as working amid the radioactive rubble, stopping up the leaks that spill radioactive water throughout the site, and handling the blobs of melted nuclear fuel. Many of the tasks will be accomplished by newly invented robots that can go where humans fear to tread."

    I figure a small 50-20 kiloton atomic bomb should do the trick...

    Some tasks are difficult because of the assorted parameters that you have to adhere to while doing them. In this case, relatively low tolerance for irradiation of workers and human morbidity and mortality are probably major inconveniences.

    This being so, it seems only logical to employ TEPCO management as decommisioning operators. It's not like they were good for whatever their existing job descriptions are, and we can safely value their radiation exposure as unimportant, or even a benefit.

    Meh, you just need to engineer it so it blows UP.
    Vertical, one shot, with enough pressure to propel each reactor at escape velocity.
    I'd do the math for you, it's elegant, but there isn't enough space in this comment.

    The "37 years remaining" reminded me of the old joke: A museum guide tells visitors "...and this ancient artifact is six thousand and thirteen years old". A tourist asks: "How do the scientists know that so precisely?" The guide responds: "I don't know how they did that, but when I got the job thirteen years ago, they told me it was six thousand years old". (Or something along the lines of this...)
