| Abstract Scope |
Non-destructive characterization of nuclear materials such as cladding materials or nuclear fuels are often difficult to perform due to the scarcity of samples prepared under conditions similar to commercial reactor environments, but also because handling some of these materials at a research facility (where neutrons sources are often located) requires special radiation precautions. In addition, penetration through high-Z materials in nuclear fuels causes a major challenge for most probing techniques.
Neutrons are sensitive to light elements such as hydrogen and are not easily attenuated by heavy elements. Hence, neutron scattering techniques offer a unique insight into materials that are critical to nuclear industry. At research reactors, neutron computed tomography is a 3D technique capable of identifying defects such as cracks and porosity, but also the presence of hydrogen in cladding material for example. Spallation neutron sources offer unique neutron-wavelength dependent characterization capabilities (i.e. the material’s crystalline structure and isotopic content).
