Abstract

Simultaneous exposure of 316L stainless steel to a proton beam and high purity water containing 3 wppm H2 was used to study the effect of radiation on corrosion. Protons create displacement damage in the solid and radiolysis products in the water. Irradiations lasted 24 h at a damage rate of 7 × 10−7 dpa/s. The 316L was solution annealed at 1050 °C for 30 min, 5% cold worked, and heat treated at 1100 °C for 10 min resulting in 23 μm grains. Samples were pre-characterized by EBSD to correlate grain orientation with oxide properties measured by Raman spectroscopy and TEM. Following irradiation, hematite was identified exclusively in areas exposed to radiolyzed water, both under the beam and downstream. Inner oxide layers in the unirradiated region had a strong dependence on grain orientation, whereas the irradiated region has little to no grain orientation dependence.
