The question of nuclear waste, hammered home by the anti-nuclear crowd, has long since been answered. And the answer is: it's far from being a problem.
As for the cost of storage and decommissioning, it makes no sense if we do not give a financial order of magnitude.
At French current electricity price, a 915MW reactor will produce 1.1 billion euros of electricity over one year. A 1500MW reactor will produce 1.8 billion euros of electricity over one year.
When you sell 60 billions of euros worth of electricity per year for 60 years, even if you pay 50 billions for storage and 2 billions to decommission an entire plant, it's still quite profitable.
Responding to sarcastic, disrespectful and immature one-liners from someone obviously ignorant on the subject is neither exciting nor productive, so I'll just throw out a few points in response to your last comment without bothering to expand on them and then move on.
