There are currently 104 non-military U.S. nuclear reactors operating across the country. Together, the reactors provide roughly 20 percent of the nation's power supply. Most of the reactors are located near major population centers.
There also are dozens of reactors, weapons labs and other nuclear facilities associated with national defense.
A new nuclear plant has not been commissioned since the Three Mile Island event, although dozens that were under construction at the time have since come on line.
More recently, increased electricity use, a desire to generate homegrown energy and concern over global warming have made carbon-free nuclear power more attractive.
The government has set aside $18 billion for new nuclear plants, and the Obama administration wants to spend an additional $36 billion.
Federal regulators are currently reviewing 20 applications to build nuclear plants, and several existing facilities have applied to extend their operating licenses.
A number of Democrats, however, have questioned the U.S. commitment to nuclear power since the start of the crisis.
