Fact Sheets | National Nuclear Security Administration

The National Nuclear Security Administration established the Global Threat Reduction Initiative (GTRI) in the Office of Defense Nuclear Nonproliferation to, as quickly as possible, identify, secure, remove and/or facilitate the disposition of high risk vulnerable nuclear and radiological materials around the world that pose a threat to the United States and the international community....

The primary goal of the W76-1 LEP is to extend the life of the Submarine Launched Ballistic Missile (SLBM) W76 warhead and to complete production no later than the end of fiscal year 2021.

Sweden has been a global leader on nonproliferation, and was one of the first countries to return highly enriched uranium based spent fuel under the U.S. Foreign Research Reactor Spent Nuclear Fuel (FRR SNF) Acceptance Program, which began in 1996 as part of the Department of Energy’s National Nuclear Security Administration (NNSA). NNSA has worked collaboratively with Sweden to remove all...

As one of the leaders in nuclear technology development, Belgium’s nuclear program has covered all aspects of nuclear fuel cycle including reprocessing and operated a reprocessing plant between 1966 and 1974.

Between the 1960s and mid-1980s, Italy had an ambitious nuclear power research program which included heavy water, boiling water, light water, and fast reactors.  In 1979, Italy signed the NPT which reaffirmed its commitment to be nuclear weapons free.

At the 2012 Nuclear Security Summit, the United States, Mexico and Canada announced the successful removal of HEU from Mexico and conversion of the TrigaII Research Reactor to LEU. The HEU removal and reactor conversion were completed with international cooperation from Canada, Mexico and the United States and was supported by the IAEA.

The goal of United States Government’s nuclear security programs is to prevent the illegal possession, use or transfer of nuclear material, technology and expertise or radioactive material. Successful nuclear security relies on the integration of technology, policy, operational concepts and international collaboration to prevent acts of nuclear terrorism.

The Department of Energy’s National Nuclear Security Administration (DOE/NNSA) led the five-year effort by the U.S. Government and other International Atomic Energy Agency (IAEA) Member States to strengthen the international guidelines for the security of nuclear material. 

The threat of a nuclear facility insider, either individually or in collusion with an outsider, stealing fissile material or committing sabotage at a nuclear facility is a difficult one to accept and prevent.   The skills, knowledge, access, and authority held by some insiders make the threat difficult to mitigate. 

The Plutonium Management Disposition Agreement (PMDA) supports President Obama’s U.S. nonproliferation and energy security agenda by disposing of enough plutonium in total for 17,000 nuclear weapons, prohibiting the United States and Russia from generating any new stockpiles of separated weapon-grade plutonium from the reactors that will be used for disposition, demonstrating U.S. and Russian...

Radioactive materials are a critical and beneficial component of global medical, industrial, and academic efforts. The National Nuclear Security Administration (NNSA), along with international and domestic partners, addresses radiological material security as part of its nuclear nonproliferation mission.

As part of its nuclear nonproliferation mission, the National Nuclear Security Administration (NNSA) is working to develop a sustainable means of producing the life-saving medical isotope molybdenum-99 (Mo-99), without using highly enriched uranium (HEU).
