Abstract Scope |
A study of the effects of ion irradiated microstructure on corrosion of 304SS in simulated Pressurized Water nuclear Reactor conditions was conducted. Coupons of 304SS were irradiated with 10 MeV Au ions to 10 displacements per atom (averaged over 1 μm thickness below surface). Corrosion was conducted in a recirculating autoclave in simulated PWR primary water condition (325 ℃, 2200 psi, 30 cc H2/kg of H2O at STP) for 1, 8,14, 21 and 35 days and 63 days. Transmission Electron Microscopy (TEM) of cross-sectional samples was used to characterize the oxide and its growth kinetics through oxide-thickness measurements in both irradiated and non-irradiated regions. Results showed differences in oxide thickness and shape between irradiated and non-irradiated regions although the oxide phases were similar. A discussion was conducted to substantiate the effects of irradiation. |
