Oxygen embrittlement of fuel sheathing resulting from high temperature oxidation in steam is a potential fuel failure mechanism during a loss-of-coolant accident (LOCA). In high temperature steam, Zr alloys from an outer layer of (ZrO/sub 2/) and an inner layer of oxygen-stabilized ..cap alpha..--Zr immediately below. The metal/steam reaction for Zr--2.5Nb in the temperature range 1000 to 1600/sup 0/C was studied and compared with earlier results for Zircaloy-2 and Zircaloy-4.
