ABSTRACT:
This is a material for lining reactor fuel element cladding. Rather than using unalloyed zirconium, this invention utilized for a 0.1-4% tin alloy liner for the cladding. The very low metallic impurities to reduce solid solution strengthening and second phase formation and property variability from lot to lot, while using alloying to reduce the susceptibility to steam corrosion. Preferably, oxygen is controlled to a very low level as well, to provide a low, but fabricable, hardness in the alloyed liner material.
