Evaluation of ferritic alloy Fe-2 1/4Cr-1Mo after neutron irradiation: irradiation creep and swelling

Description

Irradiation creep and swelling measurements are reported for Fe-2 1/4Cr-1Mo after irradiation by fast neutrons over the temperature range 370 to 5700C. Diameter change measurements on thin walled pressurized tubes in a bainitic condition and density change measurements on rods in a nonstandard condition were made following irradiation in the Experimental Breeder Reactor II. The irradiation creep specimens were irradiated to a fluence of 5.7 x 1022 n/cm2 (E > 0.1 MeV) or 30 dpa and the swelling specimens were irradiated to a peak fluence of 2.4 x 1023 n/cm2 or 115 dpa. These results have been used as a basis to establish in-reactor creep and swelling correlations for 2 1/4Cr-1Mo in a bainitic condition. The correlations predict moderate swelling and moderate irradiation enhanced creep at 3900C to 4800C. The in-reactor creep data at 5700C indicates that thermal creep mechanisms become important at this irradiation temperature
