Lawrence Livermore National Laboratory (LLNL or Livermore) is a Department of Energy national
security laboratory whose principal responsibility is ensuring the safety, security
and reliability of the nation's nuclear weapons through the application of advanced science,
engineering and technology. LLNL also works to prevent the spread and use of nuclear and other
weapons of mass destruction and to strengthen homeland security. LLNL supports capabilities in a
broad range of scientific and technical disciplines, applying current capabilities to existing
programs and developing new science and technologies to meet future national needs.
LLNL is managed in part by the University of California, on behalf of the Department of Energy's
National Nuclear Security Administration (NNSA). LLNL employs approximately 6,300 people and has an annual budget of
approximately $1.5 billion. The largest part of that budget supports "stockpile stewardship" - the
DOE program to maintain the safety, security, and reliability of the nation's nuclear weapons.
LLNL's sponsors include - in decreasing order of support - the Department of Energy, the Department
of Defense, the Department of Homeland Security, the intelligence community, the National Institutes
of Health, NASA, and others, including industry and other federal, state, and local agencies.
