In-reactor creep experiments were performed on two heats of 20 percent cold worked Type 316 stainless steel at temperatures ranging from 380 to 720/sup 0/C. At low temperatures, irradiation creep dominated the deformation process and higher creep rates were observed in-reactor than out-of-reactor. At higher temperatures, thermal creep was dominating and in-reactor creep strains were found to be below the levels measured in pre- and postirradiation creep tests. Irradiation creep strains were generally found to increase with increasing temperatures in both the irradiation and thermal creep domain, except for temperatures near the domain boundary where the two deformation processes are of equal importance. In this region, the creep strains increased with increasing temperature, passed through a maximum, and went through a minimum near the domain boundary and subsequently increased with increasing temperature.
