| 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. |
