Irradiation creep and swelling of annealed type 304L stainless steel at @390 degree C and high neutron fluence

The objective of this effort is to determine the mechanisms involved in radiation-induced deformation of structural materials and apply these insights toward extrapolation of available fast reactor data to fusion-relevant conditions. The irradiation-induced creep and swelling of annealed AISI 304L in EBR-II at {approximately}390{degree}C have been investigated to exposures on the order of 80 dpa and compared with the behavior of AISI 316 stainless steel. It is shown that swelling and creep of various austenitic steels are strongly interactive phenomena. While swelling depends on stress, displacement rate, composition and cold-work level, the creep rate directly depends only on the stress level and the instantaneous swelling rate. The creep-swelling coupling coefficient does not appear to be very sensitive to composition, cold work level or temperature. 14 refs., 6 figs.
