NNSA: Working to Prevent Nuclear Proliferation
Feb 1, 2011

NNSA’s Office of Nonproliferation and International Security (NIS) provides leadership in the formulation and implementation of nonproliferation, nuclear security, and arms control strategies to advance U.S. national security objectives. NIS draws on and contributes to a wide range of technical resources within the U.S. National Laboratory complex, working in concert with international organizations and more than 70 countries.

NIS draws on and contributes to a wide range of technical resources within the U.S. National Laboratory complex, working in concert with international organizations and more than 70 countries.

The President’s FY 2012 budget request provides the resources required to the Administration’s nuclear security agenda. It requests $2.5 billion in FY 2012 and $14.2 billion over the next five years to reduce the global nuclear threat by detecting, securing, safeguarding, disposing and controlling nuclear and radiological material, as well as promoting the responsible application of nuclear technology and science.

Nuclear Safeguards and Security

NIS works to prevent the diversion or theft of nuclear materials and sabotage of nuclear facilities through programs that strengthen international safeguards and the security of nuclear materials and facilities worldwide. NIS implements the Next Generation Safeguards Initiative (NGSI) to develop the policies, concepts, technologies, expertise, and international safeguards infrastructure necessary to sustain and strengthen the international safeguards system as it evolves to meet new challenges over the next 25 years. Working in tandem with NGSI,  the International Nuclear Security Program strengthens global physical protection norms and practices by conducting bilateral assessments, training foreign officials, and developing and implementing new guidelines in conjunction with the IAEA and other Member States.

Nuclear Controls

NIS supports foreign governments and regional organizations in achieving nonproliferation implementation objectives by improving national systems of control and building regional capacity to detect and deter proliferation.  NIS works with more than 70 international partners to strengthen national capacities in areas such as WMD-related commodity identification training, export control licensing, border security, and nuclear forensics.  This work includes programs that mitigate the risk of expertise proliferation through science and technology engagement.

Nuclear Verification

NNSA’s nuclear verification programs negotiate, monitor, and verify compliance with international nonproliferation and arms control treaties and agreements.  The United States must maintain the ability to verify nuclear reduction agreements and detect violations of treaties and other commitments, as well as other illicit activities in violation of international law.  NIS develops technologies and procedures tailored for application at specific foreign facilities, as well as technologies designed to detect potential clandestine weapons programs or illicit diversions.

Nuclear Nonproliferation Policy

NIS provides technical and scientific expertise to assist with developing and implementing nonproliferation and arms control policy to reduce WMD risk. Containing global proliferation and implementing presidential initiatives requires the development of innovative policies and approaches.  NIS facilitates engagement in proliferation-sensitive regions and actively participates in multilateral supplier regimes.
