Surface laser treatment of zr-alloy fuel bundle material

摘要

A method for treating a Zr-alloy fuel bundle material in a nuclear reactor includes treating a surface of the Zr-alloy fuel bundle material with a laser beam generated by a solid-state laser, and a nuclear reactor including a treated Zr-alloy fuel bundle material (14). This may reduce the generation of shadow corrosion and/or reduce the propensity for interference between control blade (12) and flow channel during operation of the nuclear reactor.
