The mission of the Nuclear Smuggling Detection and Deterrence program (NSDD) (formerly Second Line of Defense) is to strengthen the capabilities and commitment of partner countries to deter, detect, and interdict illicit trafficking of nuclear and other radioactive materials within the interiors of partner countries, across international borders, and through the global maritime shipping system.
NSDD provides partner countries with the tools and training necessary to counter nuclear smuggling, thus making an essential contribution to the global nuclear detection architecture. It does this by installing radiation detection systems at high-priority locations around the world and by building a community of states that possess an indigenous capacity to deter, detect, and interdict nuclear and radioactive materials. NSDD employs the following three-pronged strategy in support of this critical global nuclear security effort:
Implementation: install and deploy fixed and mobile radiation detection systems at border checkpoints, airports and seaports, internal country locations, and maritime borders.
Sustainability: provide guidance, methodology, and practical transition support for the partner country as they assume full operational, maintenance, and management responsibilities of the implemented radiation detection systems; this includes the provision of training, workshops, and exercises.
Nuclear Forensics: work bilaterally, multilaterally, and through international organizations to increase global understanding of nuclear forensic science and support states as they develop a pre-detonation nuclear forensics capability.
