With the progressive demand for domestic energy security has driven some renewed interest in nuclear power. Since Pressure Tube (PT) is the primary containment of nuclear reactor and experience the harshest environment; thus, developing a reliable structural material is very crucial and challenging. Zr-Excel (Zr-3.5% Sn-0.8%Nb-0.8%Mo) alloy has been chosen as candidate structural material for Super Critical Water Reactor. Due to design differences of the fuel channel, a substantial improvement in deformation behavior is necessary compared to the current CANDU PT material (Zr-2.5Nb). We have investigated the effect of different heat-treatments on the Zr-Excel PT microstructures and their associated thermal creep behavior. Heat-treatments have significantly altered the initial crystallographic texture. In addition, substantial microstructural evaluation occurred which have been also estimated. Finally, thermal creep behavior has been studied at different test conditions, which are eventually correlated to their microstructure to establish a structure property relationship of the current materials.
