The fall of the Soviet Union and the end of the Cold War in the early 1990s provided impetus for establishing a Comprehensive Nuclear-Test-Ban Treaty (CTBT), and in 1992 the U.S. ceased all nuclear explosive testing. The Advanced Simulation and Computing (ASC) Program was established in 1995 to support the Department of Energy's National Nuclear Security Administration (NNSA) Defense Programs as their emphasis shifted from test-based confidence in the nuclear stockpile to simulation-based confidence. Under ASC, computer simulation capabilities are developed to analyze and predict the performance, safety, and reliability of nuclear weapons and to certify their functionality. ASC integrates the work of three Defense programs laboratories (Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories) and university researchers nationally into a coordinated program administered by NNSA.
For more information, also see the NNSA ASC Web site.
Historical information about ASC can be found in the following documents: Delivering Insight: The History of the Accelerated Strategic Computing Initiative (ASCI), The Mission of the Advanced Simulation and Computing Program, and The Role of ASC in Stockpile Stewardship. Additionally, although several years old, this video provides informative background on the ASC Program.
