The high temperature uniaxial tensile in full and/or partial-recrystallized Zr-Nb alloys were performed under temperature range below 973 K in order to assess the high temperature strength anisotropy of advanced fuel cladding material in light waste reactor. The strength anisotropy was decreased with increasing the testing temperature, as well as the ruptured-strain was exceeded 100 % under 973K condition without dependence on the tensile direction and microstructure.
