Natural gas may be cheap right now, but pound for pound you can get an order of magnitude more energy from a pound of uranium than a pound of natural gas.

Six orders of magnitude would be a better estimate.

I agree, definitely. Fission reactors are a mature technology now, with all of the groundwork laid out by our predecessors. The only things we can improve are cycle efficiency, and going back to fuel reprocessing and breeder reactors, along with the possibilty of using thorium as as fuel feedstock for a new generation of plants.
