Abstract
The structural-phase state has been investigated and content of oxygen and hydrogen in the E110 type alloy after high-temperature oxidation simulating an accident of the LOCA type has been determined. Tubular samples with a diameter of 9.13 mm and a wall thickness of 0.7 mm from the Zr—1% Nb alloy obtained on the electrolytic zirconium basis (E110), the zirconium sponge basis (E110G), and from a modified alloy Zr—1% Nb—0.12% Fe—0.13% O (E110M) were selected for the study. The samples were subjected to a steam oxidation at a temperature of 1100 °C to 18% local oxidation depth. It was found that the E110G alloy based on a zirconium sponge absorbed oxygen and hydrogen less under LOCA conditions.
