| Abstract Scope |
Neutrons are an ideal probe for characterizing nuclear fuels and moderator materials for next generation nuclear reactors as their interactions with matter create complex attenuations that result in a unique combination of isotopic specific contrast mechanisms and penetrabilities, thus making neutrons well suited for investigating both high-z materials (actinides in nuclear fuels) and low-z materials (metal hydrides). Furthermore, the high material penetrability with neutron imaging allows for in-situ measurements at extreme conditions (high temperatures or activity) where bulky sample environments are required. Presented work will include the ongoing efforts at the Los Alamos Neutron Science Center (LANSCE) to develop advanced neutron imaging capabilities on Flight Path 5 (FP5) specifically for characterizing materials for advanced reactor designs. These efforts range from thermophysical property measurements of chloride-based molten salt-, to hydrogen characterization in metal hydrides moderator materials, to post-irradiation examination with energy resolved neutron imaging of actinides in fresh and irradiated fuels. |
