ABSTRACT:
This is a process for producing material for lining reactor fuel element claddings. Rather than using unalloyed zirconium, this invention provides for an alloy liner for the cladding. The process uses ultra-slow electron beam melting of zirconium, to give 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. Oxygen is controlled to a very low level as well, and preferably only 0.1-0.4 tin is added to provide a low, but fabricable, hardness in the alloyed liner material.
