Abstract Scope |
Neutrons offer bulk, non-destructive characterization of irradiated materials for which other bulk methods, e.g. X-ray diffraction or tomography, are not suitable due to the immense gamma background emitted from the samples. In particular, pulsed neutrons provide information from the ability to resolve the neutron energy or wavelength using their time-of-flight. This enables the potential to utilize neutron absorption resonance spectroscopy to characterize the spatial distribution of isotopes, so-called energy-resolved neutron imaging or neutron resonance imaging. Here, we report on characterization of an irradiated U-10Zr-1Pd fuel (6mm diameter, <2mm thick, 3R/hr dose rate) at LANSCE as well as our efforts to develop a cask enabling pulsed neutron characterization of entire irradiation capsules (<12mm diameter, <20cm length, 900R/hr dose rate), the so-call SHERMAN (Sample Handling Environment for Radioactive Material Analysis using Neutrons) cask. |
