In-reactor creep correlation for 20% cold-worked AISI 316 stainless steel

Conference ·
OSTI ID:5332287
An empirical in-reactor creep equation has been developed for 20% cold worked 316SS. This equation is based upon creep data obtained predominately from pressurized tube specimens irradiated in the Experimental Breeder Reactor EBR-II at specific irradiation temperatures between 400 and 730/sup 0/C and to a peak fluence of 7x10/sup 22/n/cm/sup 2/ (E > 0.1 MeV). The correlation includes both thermal and irradiation-induced creep terms to model the observed primary, steady-state, and tertiary creep behaviors for this alloy. The thermal creep tertiary term has been modified to reflect the observed delay in the onset of tertiary creep for the in-reactor creep data. The correlation is compared to the in-reactor data base and the 1sigma uncertainty has been found to 30% of the calculated strain where data exist.
