Irradiation creep of annealed 304L stainless steel at low dose levels

Abstract A detailed analysis was performed with previously reported solution-annealed 304L irradiation creep data. The test was irradiated in EBR-II at a temperature of 390 °C to a maximum dose of 93.3 dpa. The test samples were un-pressurized and pressurized tubes. The stress values covered the range of 69–188 MPa. Previous investigations of the data have focused on the high dose behavior. This evaluation performed a detailed evaluation of the low dose data. The results show that the swelling independent steady state irradiation creep coefficient is equal to 0.380 × 10 −6 /MPa-dpa.
