> Maintaining waste for hundreds of years is feasible, and on a whole different scale than a 30,000 year storage plan.

Maintining nuclear waste for 500 years is not feasible. I agree that it's on a different level than 30.000 year, but we cannot predict what happens in the next 50 years, let alone the next 500 or 1000 years. The thought experiment is real simple. Look back 500 years - there is no comparison. I'm still afraid that there will be some kind of destruction of society, and who is going to take care of this stuff?
