Density change measurements have been completed on the Generation 2.0 copper alloy experiment at 411{degree}C after reaching 100 dpa. The Glidcop alloy CuAl25 continues to exhibit excellent resistance to void swelling. Welding and high oxygen levels both degrade the swelling resistance of oxide dispersion-strengthened alloys. The alloy Cu-2.0Be also resists swelling and appears to be densifying in response to the continued formation of the transmutant nickel.
