An irradiation experiment on copper alloys in the Fast Flux Test Facility (FFTF) at 430{degree}C has been completed. Four exposure levels were reached with the maximum at 98 dpa. Immersion density measurements of a wide variety of copper alloys show swelling values ranging from 1 to 64% at 98 dpa. Copper that is dispersion- strengthened with 0.25% Al{sub 2}O{sub 3} (designated Al25) appears to be the most swelling resistant and promising high conductivity alloy. The steady-state swelling rate of relatively simple copper alloys was found to be {approximately}0.5%/dpa at 430{degree}C. Both the swelling and conductivity changes of the pure copper reference alloy were found to be very reproducible. 11 refs., 4 figs., 1 tab.
