b'Seeing Fuel Damage in 3D Similar to how automobile engineers crash test cars, nuclear researchers test new fuels, materials and sensors by intentionally damaging them with neutron bombardment inside a test reactor. To assess the damage, researchers must conduct careful examinations. INL and the Heinz Maier-Leibnitz Institute at Technical University of Munich developed a digital neutron computed tomography (CT) system for INLs Neutron Radiography Reactor (NRAD). In the same way that a CT scan makes 3D X-rays of the human body, the digital neutron CT system can make 3D images of nuclear fuels and reactor components using multiple neutron radiographs. The system allows researchers to automate the imaging process, which can require hundreds of radiographs.A computer thenassembles the 2Dradiographs into a 3D image, revealingdetails impossibleto see in 2D.15'
