ASC (Advanced Simulation and Computing) Program

The Advanced Simulation and Computing (ASC) Program is a U.S. Department of Energy effort that develops high-performance computer models to simulate nuclear weapons behavior safely and reliably. Rather than conducting physical tests, ASC uses advanced supercomputers and sophisticated software to predict how weapons perform, ensuring their safety, security, and effectiveness. This approach helps maintain the nuclear stockpile without the need for actual detonations, supporting national security and scientific innovation through cutting-edge computational science.
