The primary mission of the Nuclear Energy (NE) program is to advance nuclear power as a resource capable of contributing toward the nation’s energy supply, environmental, and national security needs. To ensure that nuclear energy remains a viable energy option for the nation, NE supports research, development, and demonstration activities, when appropriate, designed to resolve the technical, cost, safety, waste management, proliferation resistance, and security challenges of increased use of nuclear energy. NE leads the federal research effort to develop nuclear energy technologies, including generation, safety, waste storage and management, and security technologies to help meet energy security, proliferation resistance, and climate goals.
