| The mission of the National Nuclear Security Administration�s Second Line of Defense (SLD) program is to strengthen the capability of foreign governments to deter, detect, and interdict illicit trafficking in nuclear and other radioactive materials across international borders and through the global maritime shipping system. The goal is to reduce the probability of these materials being fashioned into a weapon of mass destruction or a radiological dispersal device (�dirty bomb�) to be used against the United States or its key allies and international partners.       |
