LFA in Nuclear Applications: Thermal Properties for High-Reliability Materials

In nuclear applications, thermal properties play a critical role in material performance, safety and long-term reliability. Laser Flash Analysis provides valuable data for understanding heat transport in materials exposed to demanding operating conditions.

In this session, Melinda Tucker presents how LFA is used in the context of nuclear materials and related high-reliability applications. Participants will gain insight into why precise Thermal DiffusivityThermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature.thermal diffusivity and Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity data are essential, which material questions can be addressed with LFA, and how the method supports advanced research and qualification processes.
