I remember in the 1960s about experimental fast-breeder reactors that promised enough fuel for all humanity as far as anyone could anticipate. These marvels not only produced electricity from U235, they also created more fuel than they used: the ultimate recycling dream.
Then, the Jane Fonda Intellectual Society-types quickly pointed out that the fuel they produced was an enriched grade of radioactive danger and could be used for bombmaking that would kill us all. Besides, more uranium was being found for mining, so the problem became if we aren't going to recycle the spent fuel rods, where are we going to bury them?
Well, they looked and looked and decided that Yucca Mountain would be a good place. This sounded like a good idea until the folks who had Yucca in their backyards heard about it and that was the end of that; so far.
I doubt reason will prevail until it absolutely has to.
