| Abstract Scope |
Thermal conductivity, a thermal property which characterizes the capacity for a material to conduct heat energy under a specific temperature gradient and these properties can be assessed on the global (bulk) and the local (micro, nano) scales, using several techniques. Variations or anomalies of material properties on the micro/nano scale may disturb the thermal properties of the bulk material, thus having a possible effect on the overall thermomechanical performance of the bulk counterpart. In this study, we are investigating the effect of material variations –packing fraction and uranium content – to the overall thermal properties of fueled TRi-structural ISOtropic (TRISO) compacts (surrogate (ZrO2), and natural Uranium). To measure bulk thermal conductivity of TRISO fuel compacts, a steady-state measurement system based on the guarded-comparative-longitudinal heat flow technique will be designed, built, and analysis will be made for use at high temperatures. |
