The Department of Energy's National Nuclear Security Administration (NNSA), which has unique expertise in nuclear weapons and nuclear material, plays a key role in the U.S. government's comprehensive effort to secure high-priority radiological material.
The National Nuclear Security Administration is responsible for designing and maintaining a nuclear stockpile that is safe, reliable and effective in order to meet the national security requirements outlined by the President.
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...
The National Nuclear Security Administration (NNSA) helps convert research reactors around the world from the use of highly-enriched uranium (HEU) fuel to low-enriched uranium (LEU) fuel as a crucial part of its nuclear security mission. Reactor Conversion is part of NNSA’s Global Threat Reduction Initiative (GTRI) to develop and implement technologies to minimize and, to the extent possible...
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.
Molybdenum-99 (Mo-99) is used to produce technetium-99m (Tc-99m), a medical isotope that is used in about 100,000 diagnostic medical procedures globally every day. Today, Mo-99 is produced at aging facilities in Europe, Canada and South Africa primarily using highly-enriched uranium (HEU) – a weapons-usable material.
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.
For nearly two decades, the United States and Ukraine have cooperated on a broad range of nuclear security and nonproliferation issues. Ukraine has a long and significant history in supporting nuclear nonproliferation. Starting in 1990s, following the breakup of the Soviet Union, Ukraine voluntarily gave up its remaining nuclear weapons and joined the Nuclear Nonproliferation Treaty as...
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 National Nuclear Security Administration (NNSA) helps convert research reactors around the world from the use of highly-enriched uranium (HEU) fuel to low-enriched uranium (LEU) as a key part of its nuclear nonproliferation mission.

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.
Under International Atomic Energy Agency (IAEA) safeguards agreements, States are required to establish a “state system of accounting and control” (SSAC) to keep track of all nuclear material (quantity and type), note changes in material inventories (imports/exports), and monitor all material balance areas (for material use and/or processing) within safeguarded nuclear facilities.
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.
A Center of Excellence (COE) for nuclear security is a centralized location where a country or region can send professionals for training in various aspects of nuclear security. These Centers advance the U.S. nuclear security agenda by highlighting the importance of strengthening nuclear security worldwide and working to address the need for capacity building, technology development,...
Since the events of September 11, 2001, security requirements for nuclear facilities have increased primarily due to changes in the Design Basis Threat against which planned facilities are designed and existing physical security systems are tested. As a result, security costs and operational impacts have increased significantly because facilities originally were not designed with...
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.
The permanent disposition of Highly Enriched Uranium (HEU) permanently reduces nuclear security vulnerabilities. In 1996, the Department of Energy (DOE) announced plans to reduce stockpiles of surplus HEU by down-blending, or converting, it to low-enriched uranium (LEU).
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).
