2006 Department of Energy Strategic Plan - Ensuring America’s nuclear security

In 2000, the National Nuclear Security Administration (NNSA) was established as a new element within the Department in response to a Congressional mandate to reinvigorate the security posture throughout the nuclear weapons program and to reaffirm the Nation’s commitment to maintaining the nuclear deterrence capabilities of the United States. NNSA was chartered to better focus management attention on enhanced security, proactive management practices, and mission focus within the Department’s national defense and nonproliferation programs. The Department performs its national security mission involving nuclear weapons and nuclear materials and technology through the NNSA.
