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.

Position-sensitive detectors (PSDs) have been used in neutron tomography and nanostructural characterization of material using neutrons that scattered from a monochromator of highly oriented pyrolytic graphite type, placed directly in the neutron beam in the Small Angle Neutron Scattering (SANS) facility at the Malaysian Nuclear Agency. PSD uses the 3He(n,p) reaction to detect neutrons. Because of the 3He high neutron cross section of 5333 b at 25.3 meV, a PSD is suitable for neutron detection across its axial direction at a low neutron flux of 103 cm−2‧s−1. Because of its insensitivity toward gamma radiation, the signals from the PSD for real neutrons are relatively easy to analyze. This paper discusses the use of a PSD in neutron tomography and nanostructural characterization of material in the SANS facility at the Malaysian Nuclear Agency.
