How may the Nuclear Power Plant energy production method change in the future?

The future of nuclear energy depends on safe and efficient reactor designs. In the past, the United States took the approach of having a few reactor types, but every plant was basically unique. This means that personnel can not easily switch facilities without relearning the plant's design. France, on the other hand, started out with a basic plant design. While they have improve the design with newer technologies, it still means that there is a much shorter learning curve to get personnel familiar with a new plant.
