Sure, there are plenty of interesting proposals for Uranium extraction and breeders. What worries me is that despite decades of large-budget research, most of them have never been successfully demonstrated. I don't think that hoping for all the technological problems to disappear is a very good strategy. On top of that, even with current easily accessible Uranium sources, nuclear energy is significantly more expensive than both fossil fuels and renewables. I don't see that getting better with even more complicated reactor technologies.
