Innovation for advanced fuels at SRNL
As the only Department of Energy Office of Environmental Management–sponsored national lab, Savannah River National Laboratory has a history deeply rooted in environmental stewardship efforts such as nuclear material processing and disposition technologies. SRNL’s demonstrated expertise is now being leveraged to solve nuclear fuel supply -chain obstacles by providing a source of high-assay low-enriched uranium fuel for advanced reactors.

Data from a single defected fuel element operating in-reactor are used to develop a physically based model for describing the increased release of iodine and noble gas fission products to the primary coolant following a reactor shutdown and start-up. Iodines are only released on reactor shutdown, whereas both species are observed on start-up. A dependence on the decay constant of λ-3/2 is typically observed for these transient releases, indicative of a source of release from fuel cracking with little holdup due to transport in the fuel-to-sheath gap.
