Sandia has a long history of leading the world on research into geologic salt deposits, especially for permanent disposal of radioactive waste.
The DOE Office of Nuclear Energy (DOE-NE) repository research and development program previously sought to provide a sound technical basis for multiple viable disposal options, increase confidence in the robustness of generic disposal concepts, and develop science and engineering tools needed to support disposal concept implementation. Sandia, Los Alamos, and Lawrence Berkeley National labs conducted research into salt, which includes the Brine Availability Test in Salt (BATS) field test at the Waste Isolation Pilot Plant (WIPP), a DOE Office of Environmental Management facility. BATS leveraged the WIPP infrastructure to advance science informing generic disposal concepts.
