Security upgrades at the Lawrence Livermore National Laboratory

Major upgrades to the physical security systems of Lawrence Livermore National Laboratory are in the form of two integrated multiyear projects: SSE-1 (Safeguards and Security Enhancements-Phase I) is a five-year effort that started in late 1984; the second five-year phase, SSE-2, began in 1986. SSE-1 upgrades obsolete operating systems and constructs the facilities needed to house the equipment. Its subprojects replace the existing alarm system, automate access-control functions, restructure security command and control, upgrade the security radio network, modernize nuclear materials accountability, construct two communications centers, and add perimeter-security features. SSE-2 consolidates and protects operations involving special nuclear materials in an area called the Superblock, as well as improving the lab-wide physical security system. SSE-2 subprojects add perimeter protection to the Superblock, construct processing facilities for special nuclear materials, construct an office complex with a secondary command and control center, build security training and housing facilities, and improve roads, fencing, and lighting
