I'm going to take my best crack at answering as many people's questions as I can in one go, so stay with me I will try to make this easy to manage
and as quick as possible with enough data to satisfy.
I've seen this one a few times, and in reality the reason they can not tell you what areas will be affected first, or last or how " Bad " They will
be hit is because for the most part, Radioactive material will be spread by Airstreams, Sea currents, rain, and winds. Some of these are easily
predictable and again, based on any given conditions the easiest answer is the northern hemisphere, although it is entirely probable the radiation
from fukushima will reach every nook and cranny around the globe. IF the nuclear material is exposed to air and catches fire it will melt down,
releasing enormous amounts of radiation into the surrounding air, if it rains the water vapour will carry radioactive material back up into the
clouds, which can later be rained down anywhere around the globe. The same goes for the ocean, water running into the ocean will pick up radioactive
particles and through ocean currents end up really anywhere!
this is a general idea, weather changes mind you...
Now, for MOX Fuel. Here is a Wiki, where I will gather most of my info for this reply. I will try to keep it simple, and what is pressing to this
situation how ever I suggest you check out the link and give it a read for yourself.
MOX fuel is a blend of surplus weapons grade plutonium and natural uranium, depleted uranium or reprocessed uranium, it's basically a convenient way
to get rid of " Excess" plutonium as well as cut corners on enriching uranium. MOX Fuel Burns Hotter and faster than typical Uranium fuel, the
plutonium contained in MOX decays faster than uranium, releasing more radiation with a shorter halflife but produces another isotope which is more
radioactive with a much longer half life. Summed, up in laymens, MOX fuel is more volatile when exposed to Air which could lead to quicker melt
down/explosion more radiation, and more danger than LEU Fuel. I tried to break it down in quick points that are of concern. MOX fuel has the potential
to release more radiation as well as form more radioactive isotopes that as well release more radiation the LEU fuel.
I can not even believe someone said this but I will give my two cents anyways, don't feed the trolls. WE can not nuke, a radioactive material spill.
This would simply take a Meltdown which is a slower process with extremely dangerous amounts of radiation and the potential to devastate Earth's
ecosystem and make the process instantaneous. Atomic bomb, + 1600 fuel rods = Atomic bomb spraying those rods obliterated into single molecules all
around the globe in minutes as opposed to years. It would still take just as long for the fall out to kill you from the instant bomb blast Dispersal(
unless you're with in the effects of the initial blast), as it would the melt down scenario. It would just be a good ol US of A version of a dirty
Why can't we place a concrete Sarcophagus over the fukushima site? Well, I suppose we could but the sarcophagus would have to be ohhhhh 85times
thicker, as well the heat produced by 85times the amount of fissile material may not allow the concrete to set successfully, and today The chernobyl
sarcophagus is falling apart and that quick fix isn't gonna hold out forever. Two different disasters can not be solved with the same band aid. Would
you use a band-aid to reattach a limb?? As well, the cracked leaky containment "pond" holding all the fuel rods is on one of the upper floors of a
building that is barely standing under it's own weight, how do we pour millions of tons of concrete over it with out compromising the structure and
potentially exposing a fuel rod to air which would cause a fire and or potentially an explosion. Nuclear fuel has to remain submerged in water at all
times, or else it will react with the air very violently. As well, there poses the same risks as chernobyl. Who wants to die to go near the plant let
alone try to work over top of it to try and encase the fuel, secure the structure of the building and make sure the fuel is in the center of several
hundred to several thousands of feet of concrete. Oh, and you'd have to get all that concrete to the site in question. I'm not trying to be harsh or
come off rude, but these are real issues one would face trying to deal with it like chernobyl. Not to mention, most people know what radiation is and
that it will kill you. Many of those that perished at chernobyl had no idea what they were in for.
