Its sadder everyday that somehow humanity has failed to become a nuclear society. All our problems could have been solved decades ago but we are still nowhere near a solution.
I used to think nuclear was the way forward, and I kind of still do, but it's understandable why it isn't prevalent. It's all about magnitude of loss/failure. Traditional power plants are much safer and failure isn't nearly as catastrophic as with nuclear. If a nuclear plant fails, look at what can happen - you can lose an entire city indefinitely - Chernobyl. The potential for loss is much higher with nuclear power.
To get a perspective of how nuclear accidents compare with those of other energy production methods, have a look at: https://en.wikipedia.org/wiki/Energy_accidents
