This presentation is focused on the current development, modeling, and implementation status of non-traditional thermal characterization techniques. These techniques are the Fluorescent Scanning Thermal Microscope (FSTM) and Raman thermometry-based techniques (RTT). The FSTM is a low cost, modular, laser-based device that uses variations in fluorescent light from a deposited dye to determine the thermal properties of a material. The FSTM has been specifically designed as a modular unit for use in hot cells. Results from the FSTM on reference materials are presented and compared to results from Idaho National Laboratory’s Thermal Conductivity microscope. Additional, FSTMv2 is presented to address the need for improved accuracy compared to the first design. A numerical comparison of potential uncertainties of multiple RTTs applied to UO2 are also presented to determine the suitability of using Raman-thermometry to measure the thermal conductivity of UO2.
