Abstract Scope A study was conducted to characterize the effects of pre-irradiated microstructure on the corrosion behavior of I600 in hydrogenated water at 2200 psi and 325 °C (representative of Pressurized Water Reactor conditions). Coupons were polished to a mirror finish and partially irradiated with either 1 MeV Ar ions or 5 MeV Ni ions to 10 dpa (as averaged over the first 100 nms). The samples were corroded in the simulated PWR environment inside a recirculating autoclave. The hydrogen level was kept around 30 cc/kg H2O at STP by continuously bubbling in an overpressure of hydrogen. Transmission Electron Microscopy (TEM) characterization was conducted after testing for several durations (7 days, 14 days, 28 days). The oxide thicknesses were measured and the oxide microstructure was characterized and compared in the irradiated vs. unirradiated areas. The effect of the irradiated microstructure on oxide growth kinetics and mechanisms is discussed.
