Waste disposal issues disappear if they're allowed to make next-gen reactors. Much less waste and much easier to store.
That is like the blind men with the elephant. You have a much larger problem than what you realize.
You've never been on a mining site. Nuclear waste needs to include the stream of unnaturally enriched uranium tillings, the water you destroy permanently to get at it from in-situ type mining, the area contaminated by good ol' wind in the processing, the waste generated during processing and further refinement to actually get a usable product, then you get to the plant itself, the daughter products, the fact that anything that actually runs water through it *leaks*, and everything else down the road.
Insane liabilities that are largely externalized, huge capital costs, higher electricity rates, and the risk of losing say 1/3 of the United States productive capacity in the event of a major accident. All of this for a system that even if it works out right produces hundreds of tons of radioactive waste for every hour that plant runs. Oh, you didn't figure the mining into your equation? Of course not, you think that stuff just magically appears at Wal-Mart?
