The advancement of new nuclear fuel compositions requires accurate knowledge of the material’s nuclear and thermal properties. The use of mixed fuel compositions could transmute fission products into lower level waste. However, the thermal properties of new fuel compositions require better understanding. The purpose of the research was to investigate the applicability of an adapted four-point probe (4PP) electrical resistivity measurement technique to determine the thermal conductivity of metallic fuels and to develop a technique and apparatus that could be used to make the measurements within a Hot Cell. In this study, a standard 4PP was used to measure the electrical resistivity of the material and determine the thermal conductivity using the Wiedemann-Franz Law. The 4PP was selected for its resistance to radiation damage and ease with which it could be used in a Hot Cell. The thermal conductivity of Steel and Aluminum samples of various geometries were measured and compared to known values to validate the approach. The approach was found to accurately measure the thermal conductivity within 5 W/m-K. The technique and apparatus developed in this study can be used in Hot Cells to measure the thermal properties of new nuclear fuel compositions.
