N2 - An isotopic tailoring experiment utilizing 59Ni has been conducted in the Fast Flux Test Facility (FFTF) to study the influence of helium/dpa ratio on neutron-induced microstructural evolution. The influence of other variables, namely composition (nickel and phosphorous variations), and cold work on swelling was also examined. The alloys, Fe-25Ni-15Cr, Fe-25Ni-15Cr-0.04P, and Fe-45Ni-15Cr, were each irradiated in four conditions: solution annealed or 20% cold worked both with and without 9Ni additions, yielding He/dpa ratios of 0.35 and 4.7 at 25Ni and 0.57 and 4.9 at 45Ni. Increases in helium were found to alter the details of microstructural evolution somewhat at 495°C, but the effect of helium was small compared to the effects of other variables studied.
