NSUF 21-4237: Understanding Metallic Fuel Relocation Using Neutron Computed Tomography
This project seeks to better understand relocation behavior of fuel in severe accident scenarios through 3D volumetric analysis using neutron computed tomography (nCT). Pin Bundle Metallic Fuel Relocation (PBR) specimens were prepared at Argonne National Laboratory (ANL) and examined with X-ray radiography which, unfortunately, did not provide the necessary penetration through the depleted uranium (DU) to visualize the internal geometric condition of the test section. However, neutron imaging is likely to have the necessary penetration to provide information about the void structure of the thickest portions of the test sections. Three samples were prepared and shipped to INL’s Neutron Radiography Reactor (NRAD) for non-destructive examination using neutrons. This project will support NRAD reactor runtime, subsequent tomographic reconstruction and image analysis of these samples.
