Lawrence Livermore National Laboratory
Lawrence Livermore National Laboratory (LLNL) applies its world-class experimental and computing resources and its multidisciplinary science and engineering expertise to help solve the important problems of our time.
Livermore's defining responsibility is ensuring the safety, security and reliability of the nation's nuclear deterrent without nuclear testing. As part of the Stockpile Stewardship Program, LLNL researchers are tackling the grand challenge of understanding the scientific details of nuclear weapons performance through nonnuclear tests and experimentally validated computer simulations. The Laboratory also is leveraging science and technology to help achieve a smaller, safer, more secure and cost-effective nuclear weapons complex that meets 21st century needs.
LLNL's national security mission is broader than stockpile stewardship, as dangers from nuclear proliferation and terrorism to energy shortages and climate change threaten both national security and global stability. Livermore's multidisciplinary science and engineering are being applied to achieve breakthroughs for counterterrorism and nonproliferation, defense and intelligence, domestic security and energy and environmental security. In addition, Laboratory expertise in scientific computing, materials science, nanotechnology, lasers and other fields is advancing basic and applied science and enhancing U.S. economic competitiveness.
LLNL is managed for the U.S. Department of Energy, National Nuclear Security Administration by Lawrence Livermore National Security, LLC.
