Sole EM-sponsored national lab addresses disposition challenges of ‘to be determined’ legacy nuclear materials

AIKEN, S.C. — The U.S. Department of Energy (DOE) keeps a detailed inventory of legacy nuclear materials housed across its complex, including disposition pathways for the materials. The National Nuclear Security Administration's Nuclear Materials Integration Division has chartered Savannah River National Laboratory (SRNL) to identify and begin developing a solution to challenges associated with the materials categorized as having a “to be determined” disposition path, such as unique fuel debris. SRNL is the sole national laboratory sponsored by DOE’s Office of Environmental Management.
