Radiation enhanced corrosion behavior of commercial and model FeCrAl alloys was examined by in-situ corrosion-irradiation tests. Corrosion experiments on 80 µm thick FeCrAl alloy samples were conducted in pure water with 2 wppm of dissolved oxygen at 288˚C, or in 320°C water containing 3 wppm of dissolved hydrogen during irradiation with 5.4 MeV protons to evaluate the corrosion behavior. The thin sample acts as a “window” to allow protons to fully penetrate and deposit their energy in the water to induce radiolysis while creating displacement damage in the metal. Under normal corrosion behavior, spinel-type oxides were found to be present under hydrogen water chemistry, while the oxygenated water tests resulted in the formation of hematite-type oxides. Under proton irradiation, only hematite was found, and oxide dissolution was also observed.
