It would take at 10 years to permit and build a new reactor.
This is a long term 50 year plan.
Understood, but this plan is only for the US, not the world. Also, the US oil reserves are declining and our population is increasing. Since the 1990 census, we have added 53 million people and the Census Brueau projects that we will have 364 million by 2030 and 400 million by 2050. We currently have 301 million people.
Nuclear power plants provide about 20% of our electricity now with coal providing more than half of it. Nuclear power won't affect gasoline consumption to power our cars. And the rest of the world isn't about to discard the internal combustion engine. As long as oil remains competitive in terms of costs, it will continue to be the major source of energy. The marketplace will/should determine where we get our energy.
