Abstract
Results have been obtained on the post-irradiation properties of various oxide dispersion strengthened copper alloys irradiated from 34 to 150 dpa at 415{degrees}C in the Fast Flux Test Facility. The GlidCop alloys strengthened by Al{sub 2}O{sub 3} continue to outperform other alloys with respect to swelling resistance, and retention of both electrical conductivity and yield strength. Several castable ODS alloys and a Cr{sub 2}O{sub 3}-strengthened alloy show increasingly poor resistance to radiation, especially in their swelling behavior. A HfO{sub 2}-strengthened alloy retains most of its strength and its electrical conductivity reaches a constant level after 50 dpa, but it exhibits a higher residual radioactivity.
