The steady-state swelling rate of EBR-II irradiated ternary alloys with less than or equal to 35% nickel appears to be approximately 5% per 10/sup 22/ n cm/sup -2/ (E > 0.1 MeV) or 1%/dpa, independent of chromium and/or nickel content and also independent of the irradiation temperature in the range 400 to 600/sup 0/C. The duration of the transient regime of swelling is sensitive to these three variables, however, tending to increase with increasing nickel or temperature or decreasing chromium content. A similar relative independence of the steady-state swelling rate on temperature has been also observed in commercial stainless steels, which also appear to be approaching a swelling rate of 1%/dpa at high fluence. There is some evidence that elemental segregation plays a role in the compositional dependence of swelling.
