Since 1990, nuclear power has consistently supplied about 19% to 20% of the electricity used in the U.S. However, very few nuclear plants have been added to the U.S. fleet over that time. Currently, the only new nuclear project in the U.S. is Southern Company’s Plant Vogtle expansion, which is expected to add two new reactors to the grid by the end of next year. Still, there are 50 reactors under construction around the world—12 of them in China—and several countries are considering adding more.
