Pure iron and nickel were irradiated in the range of 2 to 15 x 10-7 dpa/sec at 345-650 degrees C to very high neutron exposures in two fast reactors, BOR-60 and BN-350, to study void swelling and changes in mechanical properties of these two metals. Both nickel and iron swell in this temperature range with the maximum swelling rate at ~500 degrees C in nickel but possibly at <350 degrees C for iron. It also appears that the swelling rate in nickel may be dependent on the dpa rate, increasing with decreasing dpa rate.
