My dear friends, Grueling effort and no breaks.
Has not Japan's recent nuclear meltdown (with, now, four nuclear reactors) proven that we are all vulnerable (and don't think that this does not affect everyone on the planet - because the pollution into the oceans will penetrate every living thing through known ocean current patterns)?
Remember Chernoble and Three Mile Island? Nuclear energy is a ready source for power. But, it's up to you. Whether we will, collectively, find a solar power solution (which is free and silicon is also plentiful for photovoltaic cells).
But, if we want to live in a decently, harmonized world; let's all go solar.
There are too many dangers in transporting nuclear waste to secure depositories, primarily, because, during transport itself, there are dangers of spillage and, then again, deposits are generally still radioactive for at least more than 217+ years: Pu-239 decays to U-235, which has a very long half life (roughly 109 years).
Cheers,

P.S.: 109 years means that nuclear waste is still radioactive even after that time has elapsed (109 + 54.5 + 27.25 + 13.625 + 6.8125 + 3.41 + 1.7 + .85 = 217.1475 years). But then, calculate in that India has at least 56 nuclear reactors (potential - Tsunamis abound?); America has at least 104 reactors; and the list goes on and on.
Do the math, dudes! Nuclear waste will never be un-radioactive for more than your grand-grand-grand-grand-grand-grand-childrens' lives - and even beyond that. I just got tired of using the word, "grand," for each generation is only, on average, 25 years in length.
