Nuclear power, the use of sustained nuclear fission to generate heat and electricity, contributes nearly 20 percent of the electricity generated in America. The United States has used nuclear power for more than 60 years to produce reliable, low-carbon energy and to support national defense activities.
The Energy Department's Office of Nuclear Energy’s primary mission is to advance nuclear power as a resource capable of making major contributions in meeting our nation’s energy supply, environmental, and energy security needs. By focusing on the development of advanced nuclear technologies, NE supports the Administration’s goals of providing domestic sources of secure energy, reducing greenhouse gases, and enhancing national security.
Nuclear power remains an important part of our nation’s energy portfolio, as we strive to reduce carbon emissions and address the threat of global climate change.
