| Abstract Scope |
Advanced nuclear power is only made possible with a deep understanding of the nuclear materials deployed in these applications. The techniques to understand the mechanical degradation of materials or microstructural evolution have come a long way and are now standard in nuclear materials investigation. However, more unusual spectroscopy-based techniques have a lot to offer in providing additional insight into the nuclear materials world.
In this talk, we will feature two lesser-used techniques to characterize nuclear materials. We investigate laser-based techniques such as Laser Induced Breakdown Spectroscopy (LIBS), Laser Ablation ICP-MS, approaches with lasers to characterize fuel forms, liquids, and irradiated materials to obtain an understanding of elemental and isotope distribution in the material.
Additionally, we will present positron annihilation spectroscopy experiments conducted on irradiated material to gain insight into defects too small to observe with other techniques. We will investigate vacancy-type defects and their evolution under external stimuli. |
