This Second Amended Determination follows the approval of additional funding, period of performance, and new project milestones to support the project team's small-scale research and development activities to further advance their solution for effectively managing complex fluoride salt waste from reactors under the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems (ONWARDS) program. Specifically, the project team will test, validate, and finalize critical mineral capture from waste elements in fluoride salt wastes from advanced reactors. If successful, this project would dramatically reduce advanced nuclear reactor waste volume and create a system to capture valuable elements from reactor waste, ultimately reducing dependence on foreign energy sources and other minerals, thereby increasing U.S. energy security.
