Effects of Neutron Irradiation to 98 dpa on the Swelling of Various Copper Alloys

An irradiation series on copper alloys in the Fast Flux Test Facility (FFTF-MOTA) at about 450°C has been completed. Four exposure levels were reached, with the maximum at 98 dpa. Immersion density measurements of various copper alloys show swelling values ranging from 1 to 64% at 98 dpa. Minor solute additions have a pronounced influence on the irradiation resistance of the high-conductivity copper alloys. Copper dispersion-hardened with 0.25% Al2O3 (designated Al25) and precipitation-strengthened alloys MZC and CuBe are the most swelling resistant of the materials investigated. A second-generation experimental series of copper alloys to further explore the results of the current series is being irradiated in FFTF-MOTA.
