All power generation has tradeoffs. I like nuclear because it can be small, tucked away, generate _lots_ of power, and has few day to day environmental risks. Spent fuel is an issue, but there's very likely a virtuous cycle that will evolve if we start ramping up nukes again. Dry cask storage is no big deal IMHO, and something will likely evolve that either can use spent fuel or can deal with it better.
