One of the gravest threats the United States and the international community face is the possibility that terrorists or rogue nations will acquire nuclear weapons or other weapons of mass destruction (WMD). NNSA, through its Office of Defense Nuclear Nonproliferation (DNN), works closely with a wide range of international partners, key U.S. federal agencies, the U.S. national laboratories, and the private sector to secure, safeguard, and/or dispose of dangerous nuclear and radiological material, and detect and control the proliferation of related WMD technology and expertise.


Working in close collaboration with DOE laboratories, DNN develops and tests new technologies to advance U.S. capabilities to monitor nonproliferation and arms control treaty and agreement implementation, provides unique training and capacity-building programs, and engages internationally to promote nonproliferation norms and best practices through bilateral and multilateral work. The International Atomic Energy Agency (IAEA) is a core partner in these efforts.

Another primary DOE/NNSA mission is to address both state- and non-state-based proliferation of nuclear and radiological materials and associated technology and expertise. Through the Office of Defense Nuclear Nonproliferation, DOE and NNSA remove, eliminate, secure, safeguard, and manage dangerous materials, develop technologies to detect nuclear and radiological proliferation worldwide, and collaborate internationally to ensure the secure and safe expansion of global nuclear energy and other peaceful uses of the atom. 

Vision: We are committed to making the world a safer place by reducing nuclear and radiological dangers. 

Mission: To develop and implement policy and technical solutions to eliminate proliferation-sensitive materials and limit or prevent the spread of materials, technology, and expertise related to nuclear and radiological weapons and programs around the world.

Core Competencies:

  1. Remove, eliminate, and minimize the use of proliferation-sensitive materials.
  2. Safeguard and secure materials, technologies, and facilities.
  3. Detect and prevent the illicit trafficking of nuclear/radiological materials, technology, information and expertise.
  4. Provide R&D technology solutions for treaty monitoring, minimizing the use of proliferation-sensitive materials, and the application of safeguards and security.
  5. Provide unique technical/policy solutions and develop programs/strategies to reduce nuclear/radiological dangers.
