| Abstract Scope |
Post-irradiation examination (PIE) of reactor fuel components is essential to the analysis of reactor operating conditions. However, the various analysis techniques paired with the process of sample preparation is expensive and time intensive. To combat this, we have designed a multifaceted, optical analysis system that can prepare samples for mechanical testing and microscopy, as well as perform various PIE techniques within a hot cell environment. These measurements include surface element analysis, released isotope analysis, and thermal conductivity. The system utilizes laser ablation-inductively coupled plasma mass-spectroscopy (LA-ICP-MS), along with light induced breakdown spectroscopy (LIBS) to perform PIE on spent fuel materials. We expect this system to accelerate nuclear fuel materials research. We have shown the basic setup is viable to perform laser processing on hot samples in a safe manner, as well as the ability to detect gases released from laser processing. |
