报告内容简介：

Material thermophysical properties are important for the design and development of advanced nuclear energy systems. Nuclear fuels and materials, for instance, undergo significant microstructure and property changes in the harsh reactor environment. The understanding of property degradation due to neutron irradiation relies on experimental capabilities to determine material properties at different length scales. This talk will present experimental techniques based on thermal wave excitation, specifically the laser photothermal reflectance method, to determine thermal diffusivity and thermal conductivity. They can be used to measure properties of thin films or bulk material with surface lateral length of tens of micrometers, which is important for measuring thermal resistance of interfaces and ion irradiated samples. The talk will also introduce methods for determining grain boundary interface resistance of irradiated samples. The research provides not only thermal property data for the basic understanding of irradiation effect, but also tools for post irradiation examination in hot cells.
