Lawrence Livermore National Laboratory

Lawrence Livermore National Laboratory (LLNL) is a national security laboratory with responsibility for ensuring that the nation’s nuclear weapons remain safe, secure, and reliable. LLNL also applies its special expertise and multidisciplinary capabilities to prevent the spread and use of nuclear and other weapons of mass destruction and strengthen homeland security.

LLNL has pioneered the application of many technologies—from high-performance computers to advanced lasers—to meet national security needs. Today, the special capabilities developed for our stockpile stewardship and nonproliferation activities enable us to also meet enduring national needs in conventional defense, energy, environment, biosciences, and basic science. Research programs in these areas enhance the competencies needed for the Laboratory’s national security mission.

With an outstanding workforce of more than 8,000 employees, the Laboratory attains its missions goals and sustains public trust in the institution through safe, secure, and efficient operations and scientific and technical excellence. LLNL is located on a one-square-mile site in Livermore, CA. A larger (10 square miles) remote explosives testing site (Site 300) is situated 18 miles to the east. LLNL is managed by the University of California (UC) for the National Nuclear Security Administration (NNSA) within the Department of Energy (DOE).
