I live 30 miles from the most polluted nuclear site in America, the Hanford Nuclear Reservation. While the idea of nuclear energy is intriguing and practical, there are huge drawbacks from my view. Maintaining our huge nuclear waste stockpile is incredibly expensive, and we'll be dealing with it, in practical terms, forever.
Hanford has never been profitable because of these costs, and since alternative forms of energy, wind, solar, tidal, etc. exist and are getting better all the time, I would rather invest in other forms of clean, renewable energy.
