Oxygen concentrations were measured in existing phases in the wall of Zr1Nb nuclear fuel cladding tubes after the high temperature oxidation. The oxygen concentrations at the α/α+β phase boundary in the α-Zr(O) layer have been determined using WDS method. Oxygen concentrations in the prior β-Zr were measured using two experimental methods (SIMS and TEA). Consequently, the ceiling of the oxygen concentration in β-Zr has been assessed based on the results of SIMS, TEA, and microhardness measurements. Eventually, the experimental results were compared to the pseudobinary Zr1Nb-O phase diagram, calculated using CALPHAD software, with satisfactory agreement. The effect of hydrogen was also examined.
