Method for improving performance of irradiated structural materials
This patent describes a process for reducing radiation damage of nuclear reactor components. It comprises: selecting an alloy of a strong, ductile, crystalline material obtained by devitrification of a metallic glass; wherein the amorphization temperature of the metallic glass alloy is less than the melting temperature of the alloy, and greater than the lower limit of the operating temperature of the nuclear reactor; wherein the alloy does not undergo thermal neutron reactions; and wherein the alloy has low activation; processing the alloy to form components for use in a nuclear reactor; installing the components in a nuclear reactor; and operating the nuclear reactor at a temperature slightly above the amorphization temperature of the alloy.
