| Abstract Scope |
Nuclear fuel and materials are used in services under extreme environments such as high radiation field, high temperature, corrosion, and pressure conditions. Significant advancement was made in recently years to detect and observe the defects in radioactive materials and to understand its properties and behaviors via advanced characterization tools, such as high resolution 4D transmission electron microscopy (4D-TEM), atom probe tomography (APT), x-ray and neutron imaging and radiography, spacial domain thermoreflectance (SDTR), nanoscale and microscale testing, and real time in-situ tests. In this talk I will discuss defects characterization and evaluation and their impact on mechanical properties and thermal properties for novel fuel and nuclear materials for the light water reactors and the next generation advance reactors at the Post Irradiation Examination facilities at Idaho National Laboratory. The materials of interest include UN and composite fuels, TRISO fuels, metallic fuels, SiC Composites, advanced manufactured and coating materials. |
