Abstract Scope |
Understanding irradiation effects in nuclear fuels is paramount to advancing nuclear power generation, though bulk characterizations of irradiated fuels are difficult due to extreme radiation environments (>100 R/hr) resulting in a lack of non-destructive tools capable of interrogating irradiated materials. The ability of neutrons to penetrate containers as well as fuel material offer unique advanced post-irradiation examination capabilities to close this gap and potentially guide further destructive examination of smaller volumes of interest. Short pulsed neutron sources, such as LANSCE, enable characterization modalities ranging from time-of-flight diffraction to energy-resolved neutron imaging to neutron absorption resonance spectroscopy. We will present preliminary results on a 6 mm diameter, ~2mm thick slice of ATR-irradiated U-10Zr-1Pd characterized with these modalities (NSUF supported) as well as our pathway to characterize irradiated minor actinide bearing MOX pellets of the AFC-2C/2D irradiation campaign, including a cask designed to enable characterization of these samples in beamlines at LANSCE. |
