Description: The Savannah River Site (SRS) is a key Department of Energy (DOE) industrial complex responsible for the disposition of nuclear materials, waste management, environmental cleanup, and environmental stewardship. SRS processes and stores nuclear materials in support of national defense and US nuclear nonproliferation efforts. The site also develops and deploys technologies to improve the environment and treat solid and liquid nuclear and hazardous wastes left from the Cold War. While current missions remain the highest priority, SRS leadership places great importance on developing broader missions for SRS that use its unique capabilities to address critical national missions.
