From a technical standpoint Pebble-Bed reactors are a perfectly valid solution to the nuclear issue. Waste storage and disposal is much easier. Though the half-life is the same, the pebble containment lowers risk of leakage by a tremendous amount. Needs more money for further development which has been stopped by anti-nukers.
Just read about Chernobyl, Three Mile Island, not to mention Fukushima.
The anti-nuke movement, like so many others is driven by fear. the NIMBY (not in my backyard) effect reigns supreme.
However, that does not make me an anti-nuke. I believe it is a valid power source if handled properly.
