The nuclear waste problem was the biggest driver for germany's nuclear exit decision, for 30 years this was discussed and determined to be basically unsolvable. (The incident in japan led to a re-think of the exit-of-the-exit decision, but the doubts about waste handling had been there at all times).
To me, this is nuclear's biggest threat, and whenever I see discussions on slashdot this does not really seem to be an issue to US citizens at all. Why is this the case? Are these problems properly addressed in school and media? In germany, we have constantly very critical journalism regarding nuclear waste disposal, as we also have a site where waste is leaking and this proves to be a huge and expensive problem. Generally, storing waste for 10.000 years in a safe manner is not considered to be possible. (And think about the costs which occur in those timelines).
When reading slashdot, I always get the impression that people still think nuclear has a future, and that we simply have not got the right technology in place yet. To me, nuclear has been a dead end for years, and its only a matter of time that everyone needs to switch to renewables (which would happen in 20 years max). Is nuclear really considered as a real option by the general US population? Are the implications properly educated? Total costs of waste disposal and storage and the risks which remain?
